Description

The present invention relates to a heterogeneous heated aroma-generating substrate that contains at least an aroma source material, an aerosol former, and a heat-melting substance, which generates an aerosol and aroma by heat transferred from a heat source such as a heater rather than a flame, a heated aroma-generating source using the substrate, a heated aroma cartridge equipped with the source, and a method for manufacturing the substrate. In particular, the present invention relates to a heated aroma-generating substrate that is easily melted by a heat source, promotes the generation of aerosol and aroma, has high toughness, and has excellent moldability, a heated aroma-generating source using the substrate, a heated aroma cartridge equipped with the source, and a method for manufacturing the substrate.

Conventionally, the above-mentioned "heated aroma-generating substrate" has often been called "aerosol-forming substrate", but since heating causes the aroma source materials such as aromatic plants and the aroma components of the aromatic agent to volatilize along with the aerosol former that forms the aerosol, and the aerosol smoke and the aroma of the aroma source materials and aromatic agent are enjoyed by smoking, in this invention it is called "heated aroma-generating substrate". Based on this, an "aerosol-forming body" filled with an aerosol-forming substrate and an "electronic cigarette cartridge" equipped with an aerosol-forming body are called a "heated aroma-generating source" and a "heated aroma cartridge", respectively.

In recent years, as smoking bans have become more widespread in places where people gather, such as workplaces and restaurants, fewer people are smoking cigarettes by burning them with a flame. On the other hand, there has been a sharp increase in the number of people using heated smoking devices with heated aroma cartridges equipped with a heated aroma generating source formed from an aerosol former that generates an aerosol by heat transmitted from a heat source such as a heater, and a heated aroma generating base material containing an aroma source material including tobacco plants of the Solanaceae family. This heated smoking reduces the inhalation of harmful substances generated by the thermal decomposition and combustion of conventional tobacco, and technological development of various products for enjoying heated smoking is being actively carried out (e.g., Patent Documents 1 to 5).

The mechanism of such heated smoking varies depending on the form of the heated smoking device, heated aroma cartridge, etc., but a typical example is shown below. A heated aroma cartridge has a heated aroma generation source filled with a heated aroma-generating substrate at one end and a mouthpiece at the other end. When the heated aroma generation source is attached so that it comes into contact with the heat source of the heated smoking device and heated, volatiles of the aroma source material including an aerosol former and tobacco plants are released from the heated aroma generation source, and at the same time, these volatiles are sucked into the mouthpiece at the other end along with air when the smoker inhales. In this volatiles transport process, the volatiles of the aerosol former cool and condense to form a smoke-like aerosol, and other volatiles impart an aroma to the smoker's mouth and nose, resulting in the enjoyment of smoking. Therefore, in the case of heated smoking, smoking can be done at about 200 to 350°C, which is the temperature at which the aerosol formers such as glycerin and propylene glycol contained in the heated aroma-generating base material can be volatilized, i.e., the temperature at which the tobacco leaves begin to thermally decompose, and since the tobacco leaves do not burn, very little harmful substances are produced, and the amount of harmful substances inhaled by the smoker and passive smokers around the smoker is greatly reduced.

To further reduce harmful substances, materials have been designed to reduce the tobacco content in the heated aroma-generating substrate that constitutes the heated aroma-generating source. For example, non-tobacco plants that generate various aromas have been used in combination as alternative materials to tobacco plants, and even nicotine-free heated aroma-generating substrates that can be used to enjoy comfortable smoking using only non-tobacco plants without using tobacco plants at all have been developed (Patent Document 5). On the other hand, tobacco stems, leaf pieces, dust, etc. generated during the conventional cigarette manufacturing process have been used to make effective use of materials and reduce material costs.

In contrast, conventional flame smoking, which burns tobacco with a flame, requires a temperature of at least 600°C for combustion, and can reach a maximum of 900°C during smoking, resulting in the production of a significant amount of harmful substances. However, because it does not contain any components other than the tobacco plant, the burning of tobacco produces sufficient smoke to satisfy the smoker's visual desires, nicotine, which is the root cause of the smoker's addiction to tobacco, and a myriad of aromatic compounds.

Due to the fundamental difference in the mechanisms between heat-based smoking and flame-based smoking, the heated aroma-generating substrate filled into the heated aroma-generating source that constitutes the heated aroma cartridge, which corresponds to a cigarette, is made of a material that suppresses not only the aroma and nicotine that smokers desire that are generated from tobacco plants, but also the various aromas generated from non-tobacco plants.

First, as described above, the heated aroma-generating substrate is made up of an aerosol former, which is an essential material for generating an aerosol that looks like smoke without burning.

Patent documents 1 to 5 state that the heated aroma-generating substrate is composed of the following materials, which suppress not only the aroma and nicotine emitted from tobacco plants, but also various aromas emitted from non-tobacco plants.

The aerosol former, an essential component of the heated aroma-generating substrate, is a liquid such as glycerin or propylene glycol, so a highly safe binder is used to ensure that it remains in place even when mixed with tobacco and non-tobacco plants. Typical examples include polysaccharide-based natural polymers and cellulose-based natural polymers. Furthermore, cellulose fiber may be added to increase the binding strength of these and allow them to be molded into a columnar heated aroma-generating substrate.

In addition to serving the same purpose, microcrystalline cellulose may be added as a molding agent to reduce shrinkage of the heated aromatic base material when it dries and to improve its moldability.

When fragrances, such as cooling agents or nicotine, are used to supplement the aromatic components, cross-linked polyvinylpyrrolidone or cyclodextrin, which function as adsorbents, may be included to ensure that these are stably retained without being released until the optimal smoking temperature is reached.

As such, the heated aroma generating substrate that forms the heated aroma generating source provided in the heated aroma cartridge in heated smoking requires the use of a large number of materials that inhibit the generation and volatilization of smoke components and aroma components due to heating, such as binders, molding agents, and sorbents, other than the aerosol former that is the smoke component, and the tobacco plant, non-tobacco plant, and aroma that are the aroma components, and it is not easy to generate smoke and aroma that smokers can fully enjoy.

As a method for solving this problem, Patent Document 6 proposes a homogenized tobacco material, i.e., a homogenous heated aroma-generating substrate, formed by a casting method from a slurry, which is a tobacco powder dispersion liquid of a solution in which natural wax derived from plants with a melting point of 50 to 150°C is dissolved in an aerosol former. However, this method is considered to be insufficient, and Patent Document 7 proposes a solution in which a plant-derived oil with a melting point of 20 to 50°C is introduced.

Special Publication No. 2008-518614 Special Publication No. 2010-520764 Special Publication No. 2013-519384 Special Publication No. 2016-538848 Patent No. 6280287 Patent No. 6433626 Patent No. 6442110

As described in the Background Art, smoking using a heated aroma cartridge equivalent to a cigarette, with at least a heated aroma source and a mouthpiece connected, and a heated smoking device, and by attaching the heated aroma source to the heat source of the heated smoking device, is healthy because it reduces the inhalation of harmful substances such as nicotine. However, the heated aroma generating base material that forms the heated aroma generating source contains an aerosol former that is a smoke component, as well as tobacco plants, non-tobacco plants, and aromatics that are aromatic components, but requires the use of many materials that inhibit the generation and volatilization of smoke components and aromatic components due to heating, such as binders, molding agents, and sorbents, making it difficult to generate smoke and aroma that smokers can fully enjoy.

The present invention aims to provide a heated aroma-generating substrate that generates sufficient volatile substances from the aerosol former, which is a smoke component, and from aroma source materials and aromatic agents, such as tobacco plants and non-tobacco plants, which are aromatic components, using the heat source of a heated smoking device, allowing smokers to enjoy the smoke and aroma to their satisfaction, a heated aroma-generating source using this substrate, a heated aroma cartridge equipped with this source, and a method for manufacturing this substrate.

The inventors of the present invention have hypothesized that if the heated aroma generating substrate forming the heated aroma generating source provided in the heated aroma cartridge has a phase separation structure in which a thermally fusible substance containing an aroma source material and/or an aromatic, i.e., an aromatic thermally fusible powder, is uniformly dispersed, the amount of volatilization of the aroma components and smoke components can be increased based on the following hypothesis.

First, by phase separation between the aroma source material and/or aromatic agent and the aerosol former, each of them becomes more likely to volatilize when contacted with a heat source. In particular, by distributing the aroma source material and/or aromatic agent, which volatilize the aromatic components when exposed to a heat source, unevenly in the thermally melting substance, the concentration of the aroma source material and/or aromatic agent can be locally increased compared to when present throughout the heated aroma-generating substrate, and the aromatic components can be volatilized more efficiently by contact with the heat source. Second, due to the high thermal fluidity of the thermally melting substance, the volatile components of the aroma source material and/or aromatic agent generated therein move together with the aerosol former to the surface of the heated aroma-generating substrate, promoting volatilization. Third, the thermally melting substance, such as wax, has a weaker interaction with the aromatic components than aerosol formers, such as glycerin and propylene glycol, and the aromatic components are more likely to be released from the thermally melting substance.

On the other hand, we believe that heat-melting substances can reliably fix the fragrance source material and/or fragrance at room temperature, and also fulfill the important function of maintaining the heterogeneous structure of the heated aroma-generating base material formed by phase separation from the aerosol former. In particular, we presume that heat-melting substances with poor affinity for the aerosol former would be more preferable for maintaining this heterogeneous structure.

Based on this hypothesis, various studies were conducted on the materials constituting the heated aroma-generating substrate, the manufacturing methods, etc., and it was demonstrated that a heated aroma cartridge equipped with a heated aroma-generating source wound with a heated aroma-generating substrate having a heterogeneous structure in which aromatic heat-meltable powder containing at least an aroma source material, an aerosol former, and a heat-melting substance and in which the aroma source material and/or aromatic agent is mixed in the heat-melting substance is dispersed in the heated aroma-generating substrate, allows the smoke and aroma to be fully enjoyed when smoking with a general heated smoking device, even if the composition excluding the heat-melting substance is the same as that of conventional products, and it was confirmed that the heterogeneous structure of the heated aroma-generating substrate is stably maintained, leading to the completion of the present invention.

That is, the present invention is a heated aroma-generating substrate that forms a heated aroma generation source of a heated aroma cartridge that is attached to a heated smoking device and is heated and inhaled to generate an aerosol and aroma, and is characterized in that the heated aroma-generating substrate contains at least an aroma source material, an aerosol former, and a thermally meltable substance, and that an aromatic thermally meltable powder in which the aroma source material is mixed with the thermally meltable substance is uniformly dispersed in the heated aroma-generating substrate.

The minimum outer diameter of this aromatic heat-meltable powder is preferably 125 to 355 μm, more preferably 150 to 300 μm, and even more preferably 180 to 250 μm. If the outer diameter of the aromatic heat-meltable powder is too large, its total surface area is reduced, reducing the chances of contact with the heat source, leading to insufficient melting of the heat-meltable substance and a reduced amount of volatilization of the aromatic components. On the other hand, if the outer diameter of the aromatic heat-meltable powder is too small, it is difficult for the powder to form a sea-island structure in which it is uniformly dispersed in the heated aroma-generating substrate, and the powder exists as aggregated lumps, creating areas where the melting rate due to contact with the heat source is reduced, resulting in a reduced amount of volatilization of the aromatic components.

The blend ratios of the aromatic source material, aerosol former, and thermal melting substance are preferably 55-75% by mass, 20-40% by mass, and 2-15% by mass, respectively, in order to balance the amount of vaporization of the smoke components and aromatic components, and more preferably 60-70% by mass, 25-35% by mass, and 3-10% by mass.

The heat-melting substance that plays an important role in such a heated aroma-generating substrate is not particularly limited as long as it is "an organic compound that exhibits a melting point or softening point and becomes a non-Newtonian fluid when heated." Organic compounds generally called waxes are preferred, and typical examples of waxes include petroleum-based natural waxes, synthetic waxes, plant-based natural waxes, and animal-based natural waxes. In addition, various tackifiers (adhesive agents) that include rosin, which is also used as waxes, can be used. These can be used alone or as a mixture containing at least one selected from these.

Petroleum-based natural waxes are hydrocarbon compounds and therefore have little interaction with aromatic components and aerosol formers, so there is no particular limitation, and petrolatum, paraffin wax, and microcrystalline wax can be preferably used. However, there are differences in properties based on the molecular structure. Petrolatum is a mixture of branched and alicyclic hydrocarbons, with a wide melting point range of 36 to 60°C. Paraffin wax is mainly composed of linear hydrocarbons, has high crystallinity, and most have a melting point of 40 to 70°C, with a narrow melting point range. Microcrystalline wax is a mixture of branched and saturated cyclic hydrocarbons, has low crystallinity but a high molecular weight, has the highest melting point of 60 to 90°C, and has the second widest melting point range after petrolatum. As such, both are hydrocarbon compounds extracted from crude oil, but paraffin wax and microcrystalline wax have low melt viscosity when thermally melted, low surface energy, and little interaction with aromatic components and aerosol formers, making them the most suitable thermally melting substances for heated aroma-generating substrates.

Such paraffin waxes include, for example, standard products manufactured by Nippon Seiki Ro Co., Ltd., such as Paraffin Wax-115, 120, 125, 130, 135, 140, 145, 150, and 155, all of which are preferably used. In addition, special paraffin waxes, such as the HNP series, which is a high-purity refined paraffin wax special product manufactured by Nippon Seiki Ro Co., Ltd., the SP series for specific applications, and the EMW series, which is mainly composed of isoparaffin and manufactured by a special manufacturing method, are also preferably used. In addition, as for microcrystalline waxes, for example, any of the Hi-Mic series manufactured by Nippon Seiki Ro Co., Ltd. are preferably used.

Preferably usable synthetic waxes include Fischer-Tropsch wax, polyethylene (PE) wax and modified PE wax, polypropylene (PP) wax and modified PP wax, fatty acid amides, fatty acids, fatty alcohols, polyoxyalkylene glycols, polyoxyethylene alkyl ethers, and polyoxyethylene alkyl amines.

In particular, Fischer-Tropsch wax is a linear hydrocarbon-based organic compound, so it has a low melt viscosity when thermally melted, low surface energy, and little interaction with aerosol formers and aromatic components, making it suitable as a thermally meltable material for heated aroma-generating substrates. Standard products such as Sasol's H1 (melting point: about 112°C), mid-melting point product C80 (melting point: about 85-88°C), high-melting point product C105/H105 (melting point: about 117°C), and BYK's CERAFAK (registered trademark) 117 (melting point: about 110°C) and 127N (melting point: about 120°C) can be used.

PE wax and modified PE wax, as well as PP wax and modified PP wax, are also hydrocarbon compounds and can be preferably used. Specifically, HIWAX (registered trademark) manufactured by Mitsui Chemicals, Inc., SANWAX and VISCOL manufactured by Sanyo Chemical Industries, Ltd., and CERAFAK (registered trademark) 929, 950, 913, 914, and 915 manufactured by BYK have melting points of about 94 to 161°C and can be preferably used. In particular, metallocene-catalyzed polyolefin waxes are more preferable because they have a narrow molecular weight distribution. For example, Excelex (registered trademark) manufactured by Mitsui Chemicals, Inc., which is a metallocene-catalyzed PE wax, has a melting point of 89 to 128°C because of its narrow molecular weight distribution and composition distribution, but has a low melt viscosity when thermally melted, making it an excellent polyolefin wax.

As fatty acid amides, monoamides and bisamides are suitable. As monoamides, stearic acid monoamide, oleic acid monoamide, and erucic acid monoamide are preferred, having a melting point of about 72 to 105°C. As bisamides, ethylene bisstearic acid amide and ethylene bisoleic acid amide are preferred, having a melting point of about 140 to 145°C. Although such amides have polar groups, they have a small molecular weight and no molecular weight distribution, so that their thermal melt viscosity is lower than that of waxes and oils derived from plants, and they further promote the movement of the aerosol former. For example, as monoamides, Alflow (registered trademark) S-10, E-10, and P-10 manufactured by NOF Corp. can be used, and as bisamides, Alflow (registered trademark) H series and AD series manufactured by NOF Corp. and Kao Wax EB series manufactured by Kao Corp. can be used.

As fatty acids, capric acid, lauric acid, myristic acid, pentadecylic acid, palmitic acid, margaric acid, stearic acid, arachidic acid, behenic acid, lignoceric acid, and melissic acid are preferably used since they have melting points of about 30 to 94°C. For example, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, and behenic acid are more preferable because they are industrially produced by NOF Corporation and the like.

As fatty alcohols, lauryl alcohol, tridecyl alcohol, myristyl alcohol, pentadecyl alcohol, cetyl alcohol, 1-heptadecanol, stearyl alcohol, cetostearyl alcohol, elaidyl alcohol, nanodecyl alcohol, arachidyl alcohol, heneicosanol, behenyl alcohol, lignoceryl alcohol, ceryl alcohol, 1-heptacosanol, montanyl alcohol, 1-nonacosanol, and myricyl alcohol have melting points of about 23 to 87°C and are preferably used. For example, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, and cetostearyl alcohol are more preferable because they are industrially produced by NOF Corporation and the like.

These higher fatty acids and higher aliphatic alcohols have a carboxyl group and a hydroxyl group bonded to the end of a straight-chain hydrocarbon, respectively, and have no or very narrow molecular weight distribution. Like paraffin wax, they have a low melt viscosity when thermally melted and a narrow melting point range, which is highly effective in promoting the deformation and flow of the heated aroma-generating substrate when heated.

As polyoxyalkylene glycols, those with an average molecular weight of polyethylene glycol of 600 to 11,000 are preferred, as they have a low melting point and low melt viscosity when thermally melted. Also preferred are polyethylene glycol-polypropylene glycol block polymers with 40 to 80 wt% polyethylene glycol units and an average molecular weight of 3,000 to 13,000, which have a melting point of approximately 20 to 60°C. These are also used as nonionic surfactants, but because they have a narrow molecular weight distribution and a narrow melting point range, they have excellent fluidity when thermally melted.

As a polyoxyethylene alkyl ether, polyoxyethylene monomethyl ether with an average molecular weight of 1,000 to 4,000 is preferred, as it has a melting point of approximately 40 to 55°C. This is also used as a nonionic surfactant, but has a narrow molecular weight distribution and a narrow melting point range, so it has excellent fluidity when thermally melted.

As polyoxyethylene alkylamines, polyoxyethylene-stearylamines having a melting point of about 25°C, such as NOF Corp.'s Nymeen (registered trademark) S204, and having a melting point of about 45°C, such as NOF Corp.'s Nymeen (registered trademark) S202, are preferably used. These are also used as nonionic surfactants, but have a linear hydrocarbon unit with 18 carbon atoms, a narrow molecular weight distribution, and a narrow melting point range, so they have excellent fluidity when thermally melted.

While there are no particular limitations on the natural plant waxes and natural animal waxes, preferred natural plant waxes are goby wax, urushi wax, carnauba wax, sugarcane wax, palm wax, and candelilla wax, and preferred natural animal waxes are beeswax, spermaceti wax, privet wax, wool wax, and shellac. These have relatively high melting points, can stably fix the fragrance source material and/or fragrance, and have high thermal fluidity.

However, while natural plant waxes and natural animal waxes are primarily composed of esters of fatty acids and fatty alcohols, they are mixtures of esters of fatty acids and fatty alcohols with various carbon numbers, and also contain free fatty acids, free fatty alcohols, and hydrocarbons. As they have a wide molecular weight distribution, they have a wide melting temperature range and high viscosity when melted. In addition, as they contain organic compounds with ester bonds, free fatty acids, and free fatty alcohols, they also have a large interaction with aerosol formers and aromatic components. Therefore, petroleum-based natural waxes, synthetic waxes, and rosin and rosin derivatives, which are tackifiers described below, are more preferable as heat-melting substances.

As the tackifier, rosin and rosin derivatives, as well as terpene resins and modified terpene resins can be preferably used. Specifically, as the rosin and rosin derivatives, gum rosin, rosin ester (Pencel), maleic acid modified rosin resin, and rosin modified phenolic resin (Tamanol) manufactured by Arakawa Chemical Industries, Ltd. are preferred. As the terpene resin and modified terpene resin, terpene monomer homopolymer resin (YS Resin PX and YS Resin PXN), aromatic modified terpene resin (YS Resin TO), and terpene phenolic resin (YS Polystar series) manufactured by Yasuhara Chemical Co., Ltd. are preferably used. In particular, rosin and rosin derivatives that have little interaction with aromatic components and aerosol formers and have high thermal fluidity are more preferred, and rosin is even more preferred.

As described above, there are a wide variety of heat-melting substances, but in order to uniformly disperse the aromatic heat-melting powder in the heated aroma-generating substrate of the present invention, particularly preferred are hydrocarbon organic compounds such as petroleum-based natural waxes, Fischer-Tropsch waxes, PE waxes and modified PE waxes, PP waxes and modified PP waxes, and rosin and rosin derivatives. Among these, paraffin wax, microcrystalline wax, Fischer-Tropsch wax, PE wax, PP wax,
Metallocene-catalyzed polyolefin waxes are particularly preferred.

These heat-melting substances have a melting point and a softening point. From the viewpoint of reliably fixing the fragrance source material and/or the fragrance at room temperature and of thermal fluidity when contacted with a heat source, it is preferable that the melting point is 20 to 20
A temperature range of 0°C is preferred, and a temperature range of 50 to 200°C is more preferred.

Further, the melting point of the heat-melting substance is more preferably in the temperature range of 150 to 200°C.
This is believed to be due to the following reasons: The heated aroma-generating substrate in which the aromatic thermally fusible powder of the present invention is uniformly dispersed is also formed into a columnar shape as in the conventional method, and is filled and wound in a packaging material so that the sides are in contact to form a heated aroma-generating source, which is provided in a heated aroma cartridge. When a heated aroma cartridge is attached to a heating-type smoking device and used for smoking, a heat source is inserted into such a heated aroma-generating source and heated, so that if the melting point of the thermally fusible substance of the aromatic thermally fusible powder uniformly dispersed in the heated aroma-generating substrate is low, the heated aroma-generating substrates will fuse together and the gas flow path will be blocked. Thus, until the temperature approaches the maximum temperature reached by the heat source,
In order to ensure the inhalation of the volatilized smoke and aromatic components, the melting point of the heat-melting material must be 150
It is preferably at up to 200°C.

Thus, there are few waxes that have a melting point of 150 to 200° C., and they are limited to PP wax, modified PP wax, rosin derivatives, and modified terpene resins. PP wax and modified PP wax are particularly preferably used because they have excellent thermal fluidity.
Specifically, the PP wax and modified PP wax include NP500 of Hiwax (registered trademark) manufactured by Mitsui Chemicals, Inc., and CERAFAK (registered trademark) 913 and 91 manufactured by BYK.
Examples of the rosin derivatives include Rosin Ester (Pensel) D-160 and KK manufactured by Arakawa Chemical Industries, Ltd., and Rosin Modified Phenol Resin (Tamanol) manufactured by Arakawa Chemical Industries, Ltd. Examples of the modified terpene resins include YS Polystar T160 and YS Polystar G150 manufactured by Yasuhara Chemical Co., Ltd.

On the other hand, the aromatic source materials are, in particular, Chinese tea, black tea, roses, plants of the Oleaceae family, lavender, saffron flowers, as well as shallots, garlic, onions, and the rhizomes of konjac, and Chinese quince, plants of the Rutaceae family (bitter orange, unshu mandarin, summer mandarin, ponkan, hassaku, iyokan, ichan lemon, trifoliate orange, orange, mandhari, etc.). Orange, kabosu, Kishu mandarin, quinot, grapefruit, koji, sanboukan, citron, jabara, sudachi, tachibana, tangor, natsumikan, hanayuzu, hyuganatsu, Hirami lemon (shikwasa), pomelo (pomelo), yuzu, lime, lemon, kaffir lime, etc.), plants of the Peach genus of the Rosaceae family, apples, pineapples, mangoes, kumquats, melons, pomegranates, plums, apricots,
In order to provide a pleasant aroma to smokers, the aboveground stems and leaves of plants of the genus Nicotiana in the family Solanaceae are suitable to be included, but are not limited to, blueberries, plants of the genus Fragrance in the family Rosaceae, raspberries, bananas, and grapes, as well as plants of the genus Mentha in the family Lamiaceae (peppermint, Japanese mint, apple mint, water mint, Corsican mint, pennyroyal mint, etc.), plants of the genus Mentha in the family Lamiaceae (spearmint, horse mint, green mentha, chili peppermint, ginger mint, etc.), catnip, lemon balm, savory, willow mint (hyssop), and Nicotiana species in the genus Nicotiana in the family Solanaceae.

However, it is preferable for the heated aromatic cartridge to have all three elements: fragrance, which is defined as the aroma that wafts from the heated aromatic cartridge itself when it is attached to a heated smoking device; aroma, which is defined as the aroma that wafts into the air when the heated aromatic cartridge is heated; and flavor, which is defined as the aroma that wafts into the mouth when the heated aromatic cartridge is heated and inhaled together with the aerosol.

The fragrance preferably contains at least one selected from Chinese tea, black tea, rose, a plant of the genus Osmanthus of the family Oleaceae, lavender, saffron flowers, and above-ground stems and leaves of a plant of the genus Nicotiana of the family Solanaceae.

The aroma preferably includes at least one selected from the underground stems of scallions, shallots, garlic, onions, and konjac, and the above-ground stems and leaves of plants of the genus Nicotiana and Nicotiana species of the family Solanaceae.

Flavors include Chinese quince, plants from the Rutaceae genus (citrus fruit, orange, satsuma mandarin, etc.)
Natsudaidai, Ponkan, Hassaku, Iyokan, Ichan lemon, Trifoliate orange, Orange, Mandarin orange, Kabosu, Kishu mikan, Quinotte, Grapefruit, Koji, Sanboukan, Citron, Jabara, Sudachi, Tachibana, Tangor, Natsumikan, Hanayuzu, Hyuganatsu, Hirami lemon (Shikwasa), Pomelo (Pomelo), Yuzu,
Limes, lemons, kaffir limes, etc.), plants of the Rosaceae family, apples, pineapples,
Mango, kumquat, melon, pomegranate, plum, apricot, blueberry, plants of the genus Fragaria in the family Rosaceae, raspberry, banana, and grape fruit, and plants of the genus Mentha in the family Lamiaceae (peppermint, Japanese mint, apple mint, water mint,
It is preferable that the extract contains at least one selected from among plants of the genus Nicotiana in the family Solanaceae (e.g., Corsican mint, pennyroyal mint, etc.), spearmint-type plants of the genus Mentha in the family Lamiaceae (e.g., spearmint, horse mint, green mentha, chili pepper, ginger mint, etc.), catnip, lemon balm, savory, willow mentha (hyssop), and above-ground stems and leaves of plants of the genus Nicotiana in the family Solanaceae.

The aerosol former may be propylene glycol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, glycerin, monoacetin (glycerin monoacetate), diacetin (glycerin diacetate), etc. Among them, it is particularly preferable to use at least one selected from propylene glycol, ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol, and glycerin, since this has excellent volatility upon contact with a heat source and aerosol formability that appears as smoke upon cooling.

Furthermore, it is preferable to further include an aroma agent for the purpose of supplementing the aroma source material, and it is more preferable to mix it into the thermal melting substance together with the aroma source material. As the aroma agent, at least one selected from a refreshing agent and nicotine can be used. In particular, the refreshing agent is important as a flavor, and is preferably menthol and menthol derivatives, menthone and menthone derivatives, menthane carboxylic acid amide, 2,3-dimethyl-2-(2-propyl)-butyric acid derivatives, menthane and menthane derivatives, L-carvone, xylitol, eucalyptus essential oil,
The aromatic agent is preferably 3 parts by mass of peppermint oil, spearmint essential oil, or spilanthol per 100 parts by mass of the total amount of the aromatic source material, the aerosol former, and the thermal melting substance.
The content should be up to 25 parts by mass, but if it is contained in an amount of 5 to 20 parts by mass, the aromatic components of the aromatic source material can be supplemented and there is no adverse effect such as a decrease in the strength of the heated aroma generating agent, which is more preferable.

In this way, the material constituting the heated aroma-generating substrate can improve the sensory functions such as smoke and aroma generated in contact with a heat source, but in order to mold and process the heated aroma-generating substrate into a heated aroma-generating substrate, the heated aroma-generating substrate must have releasability from a molding machine that comes into contact with the heated aroma-generating substrate, and must be protected from damage such as breakage of the heated aroma-generating substrate during molding. In addition, it is also required to reduce volumetric shrinkage after molding, prevent the heated aroma-generating substrate from falling off, and maintain stability over time such as maintaining the optimal state of the gas flow path. For this reason, it is preferable to further contain a molding agent.

The molding agent is preferably microcrystalline cellulose, and in particular, the average particle size of the microcrystalline cellulose is 7.
It is preferable that the average particle size of the microcrystalline cellulose is 0 to 120 μm. If the average particle size of the microcrystalline cellulose is 70 μm or less, the effect of suppressing the shrinkage of the heated aroma-generating substrate is obtained, and adhesion between the heated aroma-generating substrate and the molding machine cannot be prevented. If the average particle size is 120 μm or more, there is no problem with the releasability of the heated aroma-generating substrate and the molding machine, but the heated aroma-generating substrate is easily broken. In addition, the mass average molecular weight (Mw) of the microcrystalline cellulose is preferably 20,000 to 60,000. If it is 20,000 or less, there is no effect of suppressing the shrinkage of the heated aroma-generating substrate, and if it is 60,000 or more, the heated aroma-generating substrate is easily broken, causing problems in molding. In the case of this molding agent, the total amount of the aroma source material, the aerosol former, and the heat-melting substance is 10
It is sufficient if the content is 2 to 25 parts by mass relative to 0 parts by mass, but it is more preferable to include 3 to 20 parts by mass, as this will fulfill the above function while not causing any adverse effects in terms of the generation of volatile matter from the fragrance source material and the aerosol former.

The heated aroma-generating base material contains at least an aroma source material, an aerosol former, and a heat-melting substance. Since the aerosol former is in a liquid state, it binds these together to maintain a mass state.
In order to solve the above problems in molding, it is preferable to further use a highly safe binder. Representative examples include natural polysaccharide polymers and natural cellulose polymers, and it is more preferable to add cellulose fibers to further increase the binding strength of these polymers and to enable molding into a columnar, heated aroma-generating substrate.

Polysaccharide polymers include konjac mannan (glucomannan), guar gum, pectin, carrageenan, tamarin seed gum, gum arabic, soybean polysaccharides, locust bean gum,
Karaya gum, xanthan gum, agar, and the like can be used. From the viewpoints of strength and the above-mentioned moldability, glucomannan, guar gum, pectin, carrageenan, tamarin seed gum, locust bean gum, karaya gum, and xanthan gum are preferred.
The neutral polysaccharides glucomannan, guar gum, tamarin seed gum, and locust bean gum are more preferred.

As the cellulose-based polymer, carboxymethyl cellulose (CMC), carboxyethyl cellulose, hydroxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, as well as the sodium salt, potassium salt, and calcium salt of CMC, and the sodium salt, potassium salt, and calcium salt of carboxyethyl cellulose can be used. In particular, from the viewpoints of strength and moldability, the sodium salt and potassium salt of CMC, and the sodium salt and potassium salt of carboxyethyl cellulose are preferred.

Polysaccharide-based polymers and cellulose-based polymers may be used in combination. In this case, it is preferable to use glucomannan, guar gum, tamarin seed gum, and locust bean gum as the former, and sodium and potassium salts of CMC, and sodium and potassium salts of carboxyethyl cellulose as the latter, from the viewpoints of strength and moldability.

The cellulose fibers are preferably those of sugar cane, bamboo, wheat, rice, esparto, and jute, because the fiber diameter and fiber length of these are within the ranges of 5 to 25 μm and 0.25 to 6 mm, respectively, and are thinner and shorter than the cellulose fibers of other plants, but it has been found that they are more effective in binding the components of the heated aroma-generating substrate.

The binder is preferably used in an amount of 5 to 30 parts by mass per 100 parts by mass of the total amount of the fragrance source material, aerosol former, and heat-melting substance, and more preferably 8 to 28 parts by mass in order to improve strength and moldability and to avoid adverse effects on the generation of volatile matter from the fragrance source material and aerosol former, etc. The blended amount of cellulose fiber is preferably such that the ratio of polysaccharide-based polymer and cellulose-based polymer to cellulose fiber is 1:1 to 1:25 by mass in terms of binding effect.

On the other hand, if an aromatic agent is introduced without being contained in a thermal melting substance in order to supplement the aroma of the aromatic source material, the aromatic agent may volatilize and be released before the heat source of the heated smoking device reaches the optimum temperature for volatilizing the aerosol former (smoke component) and the aromatic source material (aromatic component). Therefore, the heated aroma-generating material needs to retain the aromatic agent until it reaches a predetermined temperature. Therefore, it is preferable that the heated aroma-generating material further contains a sorbent.

As described above, when the sorbent is intended for cooling agents and nicotine, hydrophilic cross-linked polymers and cyclodextrins are preferred for cooling agents, and cross-linked polyvinylpyrrolidone (PVP) is particularly preferred as a hydrophilic cross-linked polymer, since it adsorbs chemical substances having phenolic hydroxyl groups. In addition, cross-linked PVP has a nitrogen-containing five-membered heterocyclic compound similar to nicotine in its structure, and it is believed that an interaction between the two is formed, so cross-linked PVP is also suitable as a sorbent for nicotine. On the other hand, α, β, and γ-cyclodextrins are known to form inclusion compounds with chemical substances having hydroxyl groups or carboxyl groups of various sizes, and in particular, β-cyclodextrin forms an inclusion compound with menthol, making it the most suitable sorbent for menthol.

The amount of such a sorbent may be 4 to 25 parts by mass, and more preferably 5 to 20 parts by mass, in the case of crosslinked PVP, and 0.1 to 1.2 parts by mass, and more preferably 0.2 to 1.0 part by mass, in the case of cyclodextrin, relative to 100 parts by mass of the total amount of the fragrance source material, the aerosol former, and the thermal melting substance. It is even more preferable to include both.

Finally, in order to preserve the heated aroma-emitting cartridge for a long period of time, the aroma source material used is dried and insecticided, and it is necessary to include a preservative in the heated aroma-emitting substrate. In particular, potassium sorbate and/or sodium benzoate are suitable for the heated aroma-emitting substrate of the present invention, and in this case, it is preferable that the amount of potassium sorbate and/or sodium benzoate is 0.005 to 0.04 parts by mass per 100 parts by mass of the total amount of the aroma source material, the aerosol former, and the thermally melting substance.

The heated aroma generating substrate described above constitutes a heated aroma generating source on the insertion side of a heated aroma cartridge to be attached to a heated smoking device, and this heated aroma generating source is provided in the heated aroma cartridge. The present invention also provides a heated aroma generating source formed using this heated aroma generating substrate, and a heated aroma cartridge using this heated aroma generating source.

First, the heated aroma generating source formed using the heated aroma generating substrate will be described. The heated aroma generating source may be at least an assembly of the heated aroma generating substrate, but it is necessary to form the heated aroma generating source so that the needle-shaped heat source can be easily pierced and a flow path for the gas to be sucked is secured. Therefore, the heated aroma generating source of the present invention is characterized in that a columnar object formed by molding the heated aroma generating substrate is filled and wrapped in a packaging material so that the side surface of the columnar object is in contact with the columnar object. The shape of the columnar object is not particularly limited to a cylindrical shape, a prismatic shape, a granular shape, a scaly shape, etc., but a cylindrical shape is preferable in terms of satisfying the functions required for the heated aroma generating source, and a prismatic shape is more preferable. And, it is even more preferable that the columnar object is an assembly that is in contact with the side surface of the cylindrical object or the prismatic object. As a result, when attaching or detaching the heated aromatic body, the heated aroma-generating substrate does not fall off, the heat source can be easily inserted into the heated aroma-generating source, and a gas flow path is secured in the direction in which the smoke components and aromatic components flow, allowing for a comfortable smoking experience.

Considering the construction of a heated aroma cartridge, a heated aroma generating source in which the above-mentioned assembly of heated aroma generating substrates is wrapped with a heated aroma generating substrate wrapping member that is a cylindrical scroll is easy to handle and is preferable. This heated aroma generating source is also preferable in terms of preventing the heated aroma generating substrate, the collapsed heated aroma generating substrate, and the dust generated by the collapsed substrate from falling off and scattering from the heated aroma generating source. In particular, if the assembly that contacts the side surface of the cylindrical or prismatic heated aroma generating substrate is a heated aroma generating source wrapped with a heated aroma generating substrate wrapping member, it is more preferable because the heat source can be easily inserted and a gas flow path can be secured.

Next, the heated aroma cartridge equipped with the heated aroma generating source of the present invention will be described. One of the heated aroma cartridges with a simple configuration of the present invention is characterized in that the heated aroma generating source is stored in a heated aroma cartridge exterior member that is a cylindrical body, and the cylindrical space of the heated aroma cartridge exterior member excluding the heated aroma generating source is formed as a mouthpiece. Also, one of the heated aroma cartridges with a simple configuration of the present invention is characterized in that the heated aroma generating source and a cylindrical mouthpiece attached to the heated aroma generating source are stored in the heated aroma cartridge exterior member that is a cylindrical body.

This is a form peculiar to the heated aroma cartridge smoked using a heating-type smoking tool. In the case of a paper cigarette, the part where the paper cigarette is added to the mouth is almost always equipped with a filter member, which functions as a mouthpiece, and this filter member plays a role of filtering solid components of the burned smoke and adsorbing nicotine and tar to make it have a mellow taste. However, a heated aroma cartridge using a heating-type smoking tool does not burn a heated aroma source, and allows the smoke of the aerosol in which the aroma of the heated aroma source and the volatile matter of the aerosol former are cooled can be enjoyed, and the smoke does not contain solid components, and contains little or no tobacco plant in the aroma source material, so that the smoke contains little nicotine and tar, and the mouthpiece does not require a filter function. The mouthpiece of the heated aroma cartridge is not particularly limited as long as it is a cylindrical or columnar body with a gas flow path that does not feel heat from the heat source when the smoker holds it in his mouth and smokes, feels good on the lips and tongue, and has a moderate hardness that makes it easy to hold in his mouth. Therefore, the heated aroma cartridge of the present invention allows a user to enjoy a sufficiently comfortable smoking experience.

However, it is necessary to prevent the heated aroma generating substrate and the heated aroma generating source from moving toward the mouthpiece side by inhaling during smoking, and it is desirable to fully waft smoke that enhances the enjoyment of smoking. Therefore, it is preferable that the mouthpiece, which is the cylindrical space of the heated aroma cartridge exterior member, and the cylindrical mouthpiece attached to the heated aroma generating source are provided with a support member that prevents the heated aroma generating substrate and the heated aroma generating source from moving toward the mouthpiece side, or a cooling member that promotes the generation of aerosol, i.e., smoke, by cooling the volatile matter of the aerosol former. Furthermore, it is preferable to provide a filter member in consideration of the habits of cigarette lovers.

The structure of such a support member is not limited as long as it has at least a surface that contacts the heated aroma generating source and through which gas passes, and a gas flow path such as a through hole that supports the surface. Also, the structure of such a cooling member may be, but is not limited to, a porous body with open cells, a honeycomb structure, or the like, which has a gas flow path with a large contact area with the volatile matter.

In addition, the material is not particularly limited, but in the case of the support member, paper, plastic, rubber, wood, metal, ceramic, etc. can be used, but it is more preferable that the support member is made of plastic that can be molded into various shapes. The plastic may be either a thermoplastic resin or a thermosetting resin, and polyolefin resin, polyester resin, polystyrene resin, nylon resin, acrylic resin, silicone resin, fluorine resin, polyurethane resin, ethylene-vinyl acetate (EVA) resin, phenol resin, amino resin, ABS resin, and biodegradable plastic can be used, but since they will eventually become waste, poly(3-hydroxybutyrate) (PHB), poly(ε-caprolactone) (PCL), poly(butylene succinate) (PCL), etc. are preferred from the viewpoint of protecting the natural environment.
It is preferable that the material used is a biodegradable plastic such as polystyrene (PBS) or polylactic acid (PLA).

In the case of cooling members, metal compounds and the like having excellent thermal conductivity are preferable, but they are inferior in moldability and expensive. Therefore, polyolefin resins, polyester resins, polystyrene resins, nylon resins, acrylic resins, silicon resins, fluorine resins, polyurethane resins, EVA resins, phenol resins, and the like, which are inferior in thermal conductivity but excellent in productivity and cost, are used.
Amino resins, ABS resins, biodegradable plastics, etc. can be used, but from the viewpoint of protecting the natural environment, biodegradable plastics such as PHB, PCL, PBS, and PLA are preferable.

As is clear from this structure and material, the support member and cooling member also have the functions of a cooling member and a support member, respectively, but it is more preferable for the mouthpiece to be equipped with at least a support member and a cooling member, and for the support member and filter member to be arranged in this order in the longitudinal direction from the heated aroma source, so that both functions can be combined.

However, as mentioned above, almost all cigarettes are equipped with a filter element,
The habits of cigarette lovers are very important, and it is preferable to attach a mouthpiece equipped with at least a filter member to the heated aroma generating source. This filter member can also function as a support member and a cooling member, just like the support member and the cooling member, and can be used alone. In this case, it is more preferable to fill the entire mouthpiece attached to the heated aroma generating source with the filter member, since this is simple and can effectively exert the functions of the filter member, the support member, and the cooling member.

Such filter members include a plain filter using cellulose acetate fiber, which has been used in conventional cigarettes, a dual charcoal filter containing activated carbon in a plain filter, and an AFT (Advanced Filter) filter having an uneven surface.
Typical cigarette filters such as 100% cellulose acetate (100% cellulose ester) and 100% cellulose ester (100% cellulose ester) can be used, but there is no limitation on the type of fiber or structure as long as the filter has the necessary breathability for smoking. From the viewpoint of protecting the natural environment, plant fibers such as hemp and wood, as well as PHB,
It is preferable that the filter member is made of biodegradable plastic fibers such as PCL, PBS, PLA, etc. Also, it may contain a fragrance or a microcelled fragrance.

In this way, when the filter member provided separately in the mouthpiece is in contact with the heated aroma generating source, it exhibits the function of a support member, but since the heated aroma generating substrate and the heated aroma generating source clog the mesh of the filter member, it is preferable to interpose at least either a support member or a cooling member between the heated aroma generating source and the filter member. This support member or cooling member is also preferably in contact with the heated aroma generating source in order to maximize the function of preventing the heated aroma generating substrate and the heated aroma generating source from moving from the heated aroma generating source to the mouthpiece side.

Furthermore, in order for a mouthpiece to have all the functions required for it to be effective, it is even more preferable that the mouthpiece at least comprises a support member, a cooling member, and a filter member, and that the support member, cooling member, and filter member are arranged in this order in the longitudinal direction from the heated aroma source side.

On the other hand, in a heated aroma cartridge characterized in that a mouthpiece is attached to the longitudinal direction of such a heated aroma generating source and is stored in a heated aroma cartridge exterior member that is a cylindrical body, it is preferable that the heated aroma generating source and the support member, cooling member, and filter member that constitute the mouthpiece are wrapped in a mouthpiece wrapping member that is a cylindrical scroll. This is because if the heated aroma generating source and the support member, cooling member, and filter member that constitute the mouthpiece have the same shape, they are easily stored in the heated aroma cartridge exterior member, and productivity is improved. In particular, by wrapping the heated aroma generating source with a mouthpiece wrapping member, workability is greatly improved, and as described above, the falling off and scattering of the heated aroma generating substrate, the collapsed material of the heated aroma generating substrate, and the dust generated by the collapsed material are reduced.

Here, the support member, cooling member, and filter member constituting the mouthpiece can be wrapped in a mouthpiece wrapping member, which is a cylindrical scroll, in three different ways: first, the support member, cooling member, and filter member are each individually wrapped in a mouthpiece wrapping member;
and a third form in which the support member, cooling member, and filter member are wrapped and integrated with a mouthpiece wrapping material.

A typical example of such a mouthpiece ramping member is cigarette paper made of plant fibers such as hemp and wood, which are used in conventional cigarettes, but unlike cigarettes, it does not burn, so plastic films that can be rolled up can also be used, and the material is not particularly limited. General-purpose resin films such as polyolefin resins, polyester resins, nylon resins, EVA resins, and acrylic resins are preferably used, but from the viewpoint of protecting the natural environment, cigarette paper made of plant fibers and biodegradable plastic films such as PHB, PCL, PBS, and PLA are more preferable.

It is further preferable that the interface between the heated aroma-generating source and the mouthpiece be provided with a mesh to prevent the heated aroma-generating base material, the crumbling of the heated aroma-generating base material, and the dust generated by the crumbling from falling off and scattering into the mouthpiece, in order to prevent these foreign objects from entering the oral cavity due to suction and to prevent the filter member from becoming clogged, etc.

The mesh is not limited as long as it has a structure and material with openings large enough to block the heated aroma-generating substrate, the collapsed material of the heated aroma-generating substrate, and dust generated by the collapsed material, and has a function of not impeding the passage of gas. However, for example, it is preferable to use woven and nonwoven fabrics with excellent breathability made of plant fibers such as hemp and wood, and synthetic fibers such as polyolefin resins, polyester resins, nylon resins, and acrylic resins, and from the viewpoint of protecting the natural environment, plant fibers, PHB, PCL, PBS, and PLA are preferable.
It is preferable that the material used is a biodegradable plastic fiber such as the above.

In order to prevent contamination and breakdown of the heated smoking device, it is preferable that the opposite end surface of the mesh of the heated aroma generating source be provided with a cover that prevents the heated aroma generating substrate, debris from the heated aroma generating substrate, and dust generated by the debris from falling off and scattering into the chamber of the heated smoking device. In particular, since the heat source of the heated smoking device must be inserted into the opposite end surface of the mesh of the heated aroma generating source, it is more preferable that a heat source insertion hole be provided.

In the case where the cover has a heat source insertion hole, the cover may be made of, for example, plant fibers such as hemp and wood, polyolefin resin, polyester resin, or nylon resin. Woven fabrics and nonwoven fabrics made of synthetic fibers such as acrylic resins may be used, and the cover may have a structure and material that is not limited as long as it has an opening large enough to block the heated aroma generating substrate, the collapsed material of the heated aroma generating substrate, and the dust generated by the collapsed material, and does not hinder the passage of gas. From the viewpoint of protecting the natural environment, it is preferable to use plant fibers or biodegradable plastic fibers such as PHB, PCL, PBS, and PLA as the material. However, in the case where there is no heat source insertion hole, the heat source and the cover are in slight contact with each other, so it is preferable to use woven fabrics and nonwoven fabrics made of plant fibers such as hemp and wood, which have excellent breathability.

The heated aroma cartridge wrapped in the cylindrical heated aroma cartridge exterior member of the present invention has the feature that the heated aroma source and the mouthpiece, as well as the support member, cooling member, and filter member constituting the mouthpiece, can be replaced whether the space other than the heated aroma source loaded into the heated aroma cartridge housing member is the mouthpiece or the heated aroma source and the mouthpiece are loaded into the heated aroma cartridge housing member and constructed. Therefore, the heated aroma cartridge equipped with the heated aroma cartridge housing member not only allows various smokes and aromas to be enjoyed by replacing various types of heated aroma sources, but also has excellent economical efficiency because it does not need to be replaced until the support member, cooling member, and filter member deteriorate.

In addition, the heated aroma cartridge wrapped in the cylindrical heated aroma cartridge exterior member of the present invention preferably uses a heated aroma cartridge wrapping member that can be finished into a cylindrical scroll as the cylindrical heated aroma cartridge exterior member. The reason for this is that the heated aroma generating source, and the heated aroma generating source and the mouthpiece are mechanically wrapped to construct the heated aroma cartridge, so that the productivity of the heated aroma cartridge is dramatically improved.

A typical example of such a heated aromatic cartridge wrapping member is a cigarette paper made of plant fibers such as hemp and wood, which is used in conventional cigarettes, but unlike cigarettes, it does not burn, so a plastic film that can be rolled up can also be used, and the material is not particularly limited. General-purpose resin films such as polyolefin resins, polyester resins, nylon resins, EVA resins, and acrylic resins are preferably used, but from the viewpoint of protecting the natural environment, cigarette paper made of plant fibers and biodegradable plastic films such as PHB, PCL, PBS, and PLA are more preferable. However, if paper is used as the heated aromatic cartridge wrapping member and is used alone to make a mouthpiece, it is necessary to make the paper thicker or to increase the number of times the paper is rolled.

In addition, by making the heated aroma cartridge exterior member of the cylindrical body of the heated aroma cartridge of the present invention a heated aroma cartridge housing member that is a cylindrical case, new advantages can be provided. In this case, even if the heated aroma cartridge has a mouthpiece in the space other than the heated aroma source inserted into the heated aroma cartridge housing member,
Even though the heated aroma cartridge is constructed by inserting the heated aroma source and mouthpiece into this heated aroma cartridge housing member, it does not need to be rolled up like the heated aroma cartridge wrapping member, making it easier to replace the heated aroma source and mouthpiece, as well as the support member, cooling member, and filter member that make up the mouthpiece.

In order to fully realize such advantages, a heated aroma cartridge housing member is required to have a structure and material with mechanical strength and low friction coefficient that allows repeated insertion and removal of the heated aroma generating source and mouthpiece, as well as the support member, cooling member, and filter member that constitute the mouthpiece. When paper is used as the material for this housing member, a desired thickness corresponding to the mechanical strength is required, but it is preferable to use plastic, wood, metal, ceramic, etc., because it can be made thinner. In addition, considering that it can be molded into a cylindrical housing, plastic, wood, metal, ceramic, etc. are more preferable than paper, and in particular, plastic, which has excellent moldability, is more preferable.
The plastic may be either a thermoplastic resin or a thermosetting resin, and examples of the plastic include polyolefin resins, polyester resins, polystyrene resins, nylon resins, acrylic resins, silicon resins, fluorine resins, polyurethane resins, ethylene-vinyl acetate (
EVA resins, phenolic resins, amino resins, ABS resins, and biodegradable plastics can be used, but from the viewpoint of protecting the natural environment, PHB, PCL, PBS, P
It is preferable that the material be a biodegradable plastic such as LA.

Furthermore, the heated aroma cartridge exterior member of the cylindrical body of the heated aroma cartridge of the present invention is
By providing a heated aroma cartridge connecting member that is detachably connected at at least one location, it is possible to provide a heated aroma cartridge having various advantages.

First, a heated aroma cartridge can be provided, which is characterized in that a heated aroma cartridge connecting member is divided into a heated aroma source connecting part into which a heated aroma source can be loaded and a mouthpiece connecting part into which a mouthpiece can be formed, and the heated aroma source connecting part into which the heated aroma source is loaded and the mouthpiece connecting part are removably connected.

In this type of heated aroma cartridge, the heated aroma source connecting part of the heated aroma cartridge exterior member can be removed and the heated aroma source can be freely replaced more easily than in the case of a heated aroma cartridge wrapping member or a heated aroma cartridge housing member, so that smokers can enjoy a variety of aromas and smoke according to their preferences.The heated aroma source connecting part can be cleaned and used any number of times.Furthermore, as already explained, this type of heated aroma cartridge has the following features:
In the case of smoking a heated aroma cartridge using a heating-type smoking tool, the mouthpiece is not particularly limited as long as it is a cylindrical body that the smoker can easily hold in his mouth to smoke, so the mouthpiece connecting part is applied to the mouthpiece, and depending on the structure and material of the mouthpiece connecting part, a mouthpiece that is easy to hold in the mouth and has an excellent feel on the lips and tongue can be formed. Furthermore, by making this mouthpiece connecting part a mouthpiece connecting part into which a mouthpiece can be inserted, various mouthpieces that suit the smoker's preferences can be attached.

The mouthpiece inserted into the mouthpiece connecting part can also be in the same preferred form and shape as the mouthpiece described above. That is, a mouthpiece having at least one selected from a support member, a cooling member, and a filter member, a mouthpiece having at least a support member and a cooling member, and in which the support member and the cooling member are arranged in this order in the longitudinal direction from the heated aroma generating source connecting part side, a mouthpiece having at least a support member and a filter member or a cooling member and a filter member, and in which the support member and the filter member or the cooling member and the filter member are arranged in this order in the longitudinal direction from the heated aroma generating source connecting part side, and a mouthpiece having at least a support member, a cooling member, and a filter member, and in which the support member, the cooling member, and the filter member are arranged in this order in the longitudinal direction from the heated aroma generating source connecting part side. In this case, the mouthpiece connecting part can also be removed, so that the mouthpiece can be attached and detached more easily than in the case of the heated aroma cartridge wrapping member or the heated aroma cartridge housing member.

In addition, in order to facilitate insertion of the mouthpiece into the mouthpiece connecting part, it is preferable that the support member, the cooling member, and the filter member are wrapped in a mouthpiece wrapping member that is a cylindrical roll. In this case, there are three types of wrapping: the first type is that the support member, the cooling member, and the filter member are each individually wrapped in the mouthpiece wrapping member, the second type is that the support member and the cooling member, the support member and the filter member, and the cooling member and the filter member are wrapped and integrated in the mouthpiece wrapping member, and the third type is that the support member, the cooling member, and the filter member are wrapped and integrated in the mouthpiece wrapping member.

In this way, the mouthpiece inserted into the mouthpiece connecting portion may be of the same preferred form and shape as the mouthpiece already described above, and the material is also the same, so description of the material will be omitted.

Secondly, it is possible to provide a heated aroma cartridge, characterized in that the mouthpiece connecting part comprises at least two connecting parts selected from a supporting member connecting part in which a supporting member is inserted, a cooling member connecting part in which a cooling member is inserted, and a filter member connecting part in which a filter member is inserted, and at least two connecting parts selected from the supporting member connecting part, the cooling member connecting part, and the filter member connecting part are arranged in this order in the longitudinal direction from the heated aroma generating source connecting part side, and each is detachably connected. In this case, since the supporting member connecting part, the cooling member connecting part, and the filter member connecting part are each detachably connected, the supporting member,
The cooling member and the filter member must each be individually wrapped with the mouthpiece wrapping member.

That is, this heated aroma cartridge has a heated aroma generating source connecting part and a mouthpiece connecting part that are detachably connected, and further, the mouthpiece connecting part is a heated aroma cartridge in which a support member connecting part into which a support member is inserted and a cooling member connecting part into which a cooling member is inserted are detachably connected in this order in the longitudinal direction from the heated aroma generating source connecting part, and a support member connecting part into which a support member is inserted and a filter member connecting part into which a filter member is inserted are detachably connected in this order in the longitudinal direction from the heated aroma generating source connecting part. At least four types of heated aroma cartridges can be provided: a heated aroma cartridge in which a cooling member connecting part into which a cooling member is inserted and a filter member connecting part into which a filter member is inserted are detachably connected in this order in the longitudinal direction from a heated aroma source connecting part; a heated aroma cartridge in which a support member connecting part into which a support member is inserted, a cooling member connecting part into which a cooling member is inserted, and a filter member connecting part into which a filter member is inserted are detachably connected in this order in the longitudinal direction from a heated aroma source connecting part.

The configuration of this heated aroma cartridge not only allows the heated aroma source connecting part and the mouthpiece connecting part to be detachably connected, but also allows the support member connecting part, cooling member connecting part, and filter member connecting part to be detachably connected, so that not only can the mouthpiece be tailored to the smoker's preferences, but each part can be easily cleaned and only worn parts can be replaced, making it economical.

Thirdly, a heated aroma cartridge can be provided, characterized in that when the heated aroma generating source connecting part is connected to the mouthpiece connecting part, a mesh is provided between the heated aroma generating source and the mouthpiece to prevent the heated aroma generating base material, the collapse of the heated aroma generating base material, and the dust generated by the collapse from falling off and scattering into the mouthpiece connecting part.

It is also possible to provide a heated aroma cartridge, characterized in that a cover is provided on the surface of the end of the heated aroma generating source connecting part opposite the mouthpiece connecting part, for preventing the heated aroma generating base material, debris of the heated aroma generating base material, and dust generated by the debris from falling off and scattering into the chamber of the heated smoking device. In particular, it is preferable that this cover is provided with an insertion hole for the heat source of the heated smoking device.

Furthermore, it is possible to provide a heated aroma cartridge, characterized in that the heated aroma generating source connecting portion has both the above mesh and cover.

In this way, by providing the heated aroma source connecting part with a mesh and/or cover, not only can these original functions be performed, but also the heated aroma source can be easily inserted without protruding from the heated aroma source connecting part. In particular, it is preferable that the mesh and cover are detachable so that the heated aroma source can be easily inserted and removed.

Since the connecting member is repeatedly attached and detached, and paper has poor durability, it is preferable to use plastic, wood, metal, ceramic, etc., which have excellent mechanical strength. Also, considering the molding process into the cylindrical housing and the fitting part, plastic, wood, metal, ceramic, etc. are preferable, and plastic, which has excellent moldability, is more preferable. The plastic may be either a thermoplastic resin or a thermosetting resin, and polyolefin resin, polyester resin, polystyrene resin, nylon resin, acrylic resin, silicone resin, fluorine resin, polyurethane resin, ethylene-vinyl acetate (EVA) resin, phenol resin, amino resin, ABS resin, biodegradable plastic, etc. can be used, but from the viewpoint of protecting the natural environment, PHB, PCL,
It is preferable that the material be a biodegradable plastic such as PBS or PLA.

The above-described connecting parts and the method of attaching and detaching the mesh and cover are not particularly limited, but may be, for example, fitting, screwing, meshing, etc.
It is preferable that the connection be made by either a fastening mechanism (g) or a hooking mechanism. Regardless of the connection form, it is preferable to use a magnetic force, since this allows easy attachment and detachment.

The heated aroma-generating substrate of the present invention, the heated aroma-generating source which is an assembly of the heated aroma-generating substrate, the heated aroma-generating source in which the assembly is wrapped with a heated aroma-generating substrate wrapping member, and the heated aroma cartridge equipped with the heated aroma-generating source have been described above. However, the technology that forms the basis of the present invention is that the heated aroma-generating substrate constituting the heated aroma-generating source provided in the heated aroma cartridge has a phase-separated structure in which the thermally fusible substance containing the aroma source material and/or aromatic, i.e., the aromatic thermally fusible powder, is uniformly dispersed, and this is based on the method for manufacturing the heated aroma-generating substrate of the present invention. In particular, the heated aroma-generating substrate of the present invention is a material that contains at least the aroma source material, the aerosol former, and the thermally fusible substance, in which the aroma source material does not dissolve, and has completely different chemical properties from the aerosol former and the thermally fusible substance,
It has been found that the following manufacturing method is suitable for these material properties: The manufacturing method of the heated aroma-generating substrate of the present invention will be described in detail below.

The basic manufacturing method of the heated aroma base material of the present invention includes a mixed powder manufacturing step (A-I) of mixing an aroma source material and/or an aromatic agent with a heat-melting substance, a cellulose fiber manufacturing step (B) of manufacturing cellulose fiber from a fibrous plant, a material preparation step (C-I) of preparing desired materials selected from an aerosol former, an aromatic agent, a molding agent, a binder, a preservative, and water, and the mixed powder manufacturing step (A-I), the cellulose fiber manufacturing step (B), and the material preparation step (C-I).

In particular, when the thermally meltable substance contains an aromatic, it is preferable to adopt the following manufacturing method in order to make the aromatic uniformly present in the thermally meltable substance: That is, the method includes each of the steps of a mixed powder manufacturing step (A-II) of mixing an aromatic source material, an aromatic, and a thermally meltable substance, a cellulose fiber manufacturing step (B) of manufacturing cellulose fiber from a fibrous plant, a material preparation step (C-II) of preparing a desired material selected from an aerosol former, a molding agent, a binder, a preservative, and water, and a heated aroma-generating substrate manufacturing step (D) of manufacturing a heated aroma-generating substrate from the material manufactured in the mixed powder manufacturing step (A-II), the cellulose fiber manufacturing step (B), and the material preparation step (C-II), and is characterized by the mixed powder manufacturing step (A-II).

That is, the mixed powder production process (A-II) includes a drying/killing process (A-1) for drying and killing insects from the fragrance source material, and a crushing process (A-2) for crushing the fragrance source material produced in the drying/killing process (A-1).
A-2), a mixing step of mixing the heat-melting substance and the aromatic at a temperature equal to or higher than the melting temperature of the heat-melting substance (
A mixing step (A-3) and a cooling step (A-4) for cooling the mixture produced in the mixing step (A-3) to 0°C or lower.
The method includes the steps of: (a) crushing the mixture cooled in the cooling step (A-4), (b) crushing the mixture produced in the crushing step (A-4), (c) compressing and shearing the crushed material produced in the crushing step (A-2) and the crushed material produced in the crushing step (A-5) to mix them, (d) cooling the mixture produced in the crushing and shearing step (A-7) to below 0°C, and (e) crushing the mixture cooled in the cooling step (A-7), thereby producing a mixed powder of an aroma source material/aromatic agent/thermo-fusible substance. However, the cellulose fiber production step (B) is exactly the same as the above-mentioned cellulose fiber production step, and the heated aroma-emitting substrate production step (D) is different from the heated aroma-emitting substrate production step (D).
) The basic process is the same as the mixed powder manufacturing process (A-II), except for the materials.
, a cellulose fiber production process (B), and a mixing process (D-1) in which the materials produced in the material preparation process (C-II) are mixed; a compression and shear processing process (D-2) in which the mixture produced in the mixing process (D-1) is compressed and sheared to form a sheet; and a compression and shear processing process (D-
2) The method for producing a heated aroma-generating substrate includes a cutting step (D-3) of cutting the sheet produced in step (D-2).

In this way, in the mixed powder production process (A-II), the thermally fusible substance and the aromatic are mixed at a temperature equal to or higher than the melting temperature of the thermally fusible substance in the mixing process (A-3), the mixture produced in the mixing process (A-3) is cooled to 0°C or lower in the cooling process (A-4), and the mixture cooled in the cooling process (A-4) is pulverized in the grinding process (A-5), thereby converting the aromatic into the thermally fusible substance.
The presence of the aromatic substance can be ensured , and the functions of the thermally fusible substance, such as fixing and sorbing the aromatic substance and releasing the aromatic component , can be fully exhibited.

The heterogeneous heated aroma-emitting substrate manufacturing process (D) includes a compression and shear processing process (D-2)
However, the present invention is not limited to this method. It is also possible to apply a cast processing step (D'-2) using the following paper manufacturing process.

That is, the heated aroma-emitting substrate manufacturing process (D) is a mixed powder manufacturing process (AI) or
A-II), cellulose fiber manufacturing process (B), and material preparation process (C-I) or (C-
II) A slurry production step (D'-1) of mixing the materials produced in step II) to produce a slurry;
The method is characterized by comprising a casting process (D'-2) in which the slurry produced in the slurry production process (D'-1) is made into a sheet by papermaking, compression, and drying, and a cutting process (D-3) in which the sheet produced in the casting process (D'-2) is cut.

However, it must be noted that in the heated aroma-generating substrate manufacturing step (D), whether via the compression/shear processing step or via the casting processing step, temperatures above the melting point of the thermally fusible substance cannot be applied, because this would destroy the phase-separated structure of the aromatic thermally fusible powder containing the aroma source material and/or the aromatic agent dispersed in the heated aroma-generating substrate.

The heated aroma-generating substrate manufactured by any of the above-mentioned manufacturing methods is characterized in that an aromatic thermally meltable powder containing an aroma source material and/or an aromatic agent in the thermally meltable substance is dispersed in the heated aroma-generating substrate, forming a phase-separated structure, and the minimum outer diameter of the aromatic thermally meltable powder is preferably 125 to 355 μm, more preferably 150 to 300 μm, and even more preferably 180 to 250 μm. This minimum outer diameter is determined by the thermal melting property and uniform dispersibility of the aromatic thermally meltable substance, and is selected by sieving the crushed aroma source material and the thermally meltable substance containing the aromatic agent. If the outer diameter of the aromatic thermally meltable powder is too large, its total surface area is reduced, the opportunity for contact with the heat source is reduced, the thermally meltable substance is insufficient melted, and the amount of volatilization of the aromatic component is reduced. On the other hand, if the outer diameter of the aromatic heat-fusible powder is too small, it will be difficult for the powder to form a sea-island structure in which it is uniformly dispersed in the heated aroma-generating base material, and the powder will exist as aggregated lumps, creating areas where the melting rate upon contact with the heat source is reduced, thereby reducing the amount of aromatic components that volatilize.

The heated aroma generating substrate forming the heated aroma generating source provided in the heated aroma cartridge has a phase separation structure in which aromatic heat-fusible powder in which aroma source material and/or aroma agent is mixed into a heat-fusible substance is uniformly dispersed. This allows for sufficient generation of volatile substances from the aerosol former, which is a smoke component, and the tobacco plant, non-tobacco plant, and aroma agent, which are aromatic components, to provide a heated aroma cartridge that allows smokers to enjoy the smoke and aroma to their satisfaction.

First, this is based on the effect that phase separation between the aroma source material and/or aromatic agent and the aerosol former makes each more likely to volatilize when in contact with a heat source. In particular, by distributing the aroma source material and/or aromatic agent, which volatilize their aromatic components when exposed to a heat source, unevenly in the thermally melting substance, the concentration of the aroma source material and/or aromatic agent becomes locally higher than when they are present throughout the entire heated aroma-generating substrate, and this has the effect of volatilizing the aromatic components more efficiently when in contact with the heat source. Second, this is based on the effect that the high thermal fluidity of the thermally melting substance causes the volatile components of the aroma source material and/or aromatic agent generated therein to migrate, together with the aerosol former, to the surface of the heated aroma-generating substrate, promoting volatilization. Third,
This is based on the effect that the aromatic components are more easily released from heat-melting substances such as waxes because the interaction between the aromatic components and heat-melting substances is weaker than that of aerosol formers such as glycerin and propylene glycol.

On the other hand, the heat-melting substance has the effect of reliably fixing the fragrance source material and/or fragrance at room temperature and stably maintaining the structure of the heated fragrance-generating base material formed by phase separation from the aerosol former.

The present invention will be described in more detail below using embodiments, but the present invention is not limited to these, and can be implemented in various modifications within the scope that does not deviate from the gist of the present invention, and is limited only by the technical ideas described in the claims.

First, in order to specifically explain the effects brought about by the phase separation structure in which aromatic heat-meltable powder in which aroma source material and/or aroma agent is mixed into a heat-meltable substance is uniformly dispersed within the heated aroma-generating substrate constituting the heated aroma generating source provided in the heated aroma cartridge, which is the core of the present invention, Examples 1 to 4 and a Comparative Example were carried out.

A heated aroma-emitting substrate, a heated aroma-emitting source, and a heated aroma cartridge were prepared using sodium salt of , sugarcane fiber, cross-linked PVP and β-cyclodextrin as sorbents, and potassium sorbate and sodium benzoate as antibacterial agents in the following compounding ratios, and were attached to commercially available heated smoking devices, and a sensory test of the smoke and aroma was carried out by 10 heated aroma cartridge enthusiasts as subjects. Note that pure water was added to the composition because it is necessary for the molding process, but it was dried and removed after the aroma-emitting source was molded and processed.

As shown in FIG. 1-I, the heated aroma-generating substrate is prepared by a mixed powder production process (A-I) in which an aroma source material and a heat-melting substance are mixed at room temperature, a cellulose fiber production process (B) in which cellulose fiber is produced from a fibrous plant, a material preparation process (C-I) in which an aerosol former, an aroma agent, a molding agent, a binder, a preservative, and water are prepared, a mixed powder production process (A-I), and a cellulose fiber production process (C-I).
B), and the heated aroma-emitting substrate manufacturing step (D) for manufacturing a heated aroma-emitting substrate using compression and shear processing from the material produced in the material preparation step (CI).

More specifically, the process includes a step (A-I) of mixing the aroma source material and the heat-melting substance to produce a mixed powder.
The method includes a drying/killing step (A-1) for drying/killing an aroma source material, a crushing step (A-2) for crushing the aroma source material produced in the drying/killing step (A-1), and a crushing step (A-3) for crushing a thermally fusible substance.
A compression and shear mixing step (A-6) is performed in which the crushed aromatic source material produced in the crushing step (A-2) and the crushed thermally fusible substance produced in the crushing step (A-5) are roughly mixed in a Henschel mixer, and then compressed and sheared to mix. The mixture produced in the compression and shear mixing step (A-6) is heated to 0° C.
The mixture was cooled in the cooling step (A-7) and pulverized in the crushing step (A-8), and an aromatic heat-meltable powder was produced by dispersing the aromatic source material powder in the heat-meltable substance. The aromatic heat-meltable powder produced in this manner was sieved through an 80 mesh sieve to select powder with a minimum outer diameter of about 250 μm for use.

In addition, the cellulose fiber production process (B) for producing cellulose fiber from a fibrous plant uses sugarcane as the fibrous plant and comprises a pressing process (B-1) for pressing the sugarcane, a crushing process (B-2) for crushing the fibrous plant that has undergone the pressing process (B-1), a boiling process (B-3) for boiling the crushed material produced in the crushing process (B-2), a dehydration and drying process (B-4) for dehydrating and drying the boiled material produced in the boiling process (B-3), and a crushing process (B-5) for crushing the dried material produced in the dehydration and drying process (B-4). Sugarcane fiber, which is one type of binder, was produced according to these processes.

From the material thus obtained and the material prepared in the material preparation step (C-I), a heated aroma-generating substrate in which aromatic thermally meltable powder is dispersed was produced according to the heated aroma-generating substrate production step (D). That is, the aromatic thermally meltable powder produced in the mixed powder production step (A-I), the sugarcane fiber produced in the cellulose fiber production step (B), and the material preparation step (C-I) were used.
The aerosol former prepared in I), the fragrance, the sodium salt of CMC which is one of the binders, the sorbent, the preservative, and pure water are mixed in a kneader in a mixing step (D-1), and then:
The composition was formed into a sheet using a three-roll compression/shear process (D-2) so that the sheet had a thickness of 0.28±0.02 mm.
2) was carried out below the melting point of paraffin wax. The sheet thus formed was
In the cutting step (D-3) in which the sheet is cut, it is cut to a width of 1.5±0.1 mm and a length of about 240 mm, and then wrapped in paper to a predetermined filling rate. Next, the paper-wrapped heated aroma-emitting substrate is cut to a length of 11.5 to 12.0 mm and then dried to produce a heated aroma-emitting source.

The heated aroma generating sources thus manufactured were used to manufacture two types of heated aroma cartridges in order to carry out sensory tests by smoking using a heated smoking device equipped with a blade-type heat source using a heater.

As shown in FIG. 3-III-B, one is a heated aroma emitting source 1 in which a heated aroma emitting substrate assembly 1121 manufactured in this embodiment is wrapped with a heated aroma emitting substrate wrapping member 112.
10 is attached to a heated aroma generating source connecting part (I) 1031A having a female thread 10311 for fitting the heated aroma generating source connecting part, while a filter mouthpiece with a support member 123 and a filter member 122 are attached in the longitudinal direction and wrapped with a mouthpiece wrapping member 121 to be attached to a mouthpiece connecting part 1032 having a male thread 10321 for fitting the mouthpiece connecting part,
The heated aroma cartridge connecting member (A) 103A is fitted to form a connecting type heated aroma cartridge (B) 1 having a filter mouthpiece with a support member.
The compound was designated as 00-III-B(a) .

The other is a heated aroma emitting source 1, which is formed by wrapping a heated aroma emitting substrate assembly 1121 manufactured in this embodiment with a heated aroma emitting substrate wrapping member 112, as shown in FIG.
10 is attached to a heated aroma generating source connecting part (I) 1031A having a female screw 10311 for fitting the heated aroma generating source connecting part, while a support member 123, a cooling member 124, and a filter member 122 are attached in this order in the longitudinal direction and wrapped with a mouthpiece wrapping member 121 to form a filter mouthpiece 120-C1 with a support and cooling member.
After being attached to a mouthpiece connecting part 1032 having a male fitting screw 10321 for the mouthpiece connecting part, these heated aroma cartridge connecting members (A) 103A are fitted together to form a connecting type heated aroma cartridge (C) 100-III-C(a) equipped with a filter mouthpiece with a supporting and cooling member.

The support member 123 used here has the function of preventing the heated aroma generating source 110 from moving in the suction direction and cooling the volatile matter generated from the heated aroma generating source 110. As an example, the support member 123 shown in Figures 5-I and 5-II was used. The support member center 1231 is connected to both of the connecting type heated aroma cartridges 100-II and 100-III.
A first support member peripheral portion 1231 is located along the central axis of the X direction of the support member 1231 and extends in the radial direction with the support member central portion 1231 as the center of symmetry.
32A and second support member perimeter 1232B form support member perimeter 1232.
The space formed between the first support member peripheral portion 1232A and the second support member peripheral portion 1232B facing each other becomes the gas flow path 1233. The outermost periphery of this support member peripheral portion 1232 is wrapped around the mouthpiece wrapping member 121 via an adhesive and fixed to its inner surface.

The internal structure of the heated aroma generating source 110 will be described with reference to an example of a heated aroma generating source 110 in which the heated aroma generating substrate 112 is placed in the longitudinal direction on the heated aroma generating substrate wrapping member 111 and rolled up, and the heated aroma generating substrate aggregate 1121 is wrapped around the heated aroma generating substrate wrapping member 111. Figure 4 shows a schematic cross-sectional view. When the heated aroma generating substrates 112 are assembled, a large number of heated aroma generating substrate aggregates 112A are formed, and gas flow paths are generated within the aggregates 112A, such as a primary aggregate flow path 112B created by the positional deviation of the heated aroma generating substrate 112, a secondary aggregate flow path 112C generated between the aggregates 112A, and a substrate-wrapping member gas flow path 112D, which is the space between the heated aroma generating substrate 112 and the heated aroma generating substrate wrapping member 111. Therefore, the volatile matter generated by heating is
The smoker can inhale aroma and smoke with a stable airflow through these gas flow paths. All heated aroma emitting sources of the heated aroma cartridge of the present invention described below have a similar internal structure. A predetermined number of heated aroma emitting sources 111 cut into rectangular columns are bundled together to form heated aroma emitting source 110, so that the smoker can inhale volatiles generated by heating with a stable airflow.

The sensory test involved subjects who were smokers using the two types of connecting type heated aroma cartridges mentioned above.
The heated aroma cartridge 100-III-B(a) and the heated aroma cartridge 100 -III-C(a) were smoked and evaluated as follows.
The connecting type heated aroma cartridge 100 -III-B(a) is attached to the chamber 202 formed in the body 201 of the heated smoking device 200 , and the heat source 203 provided in the center of the bottom of the chamber 202 is inserted into the heated aroma generating source 110, and the heated aroma generating source 110 is heated under electronic control, allowing smoking.
was also used in a sensory test.

As a comparative example, the composition of the heated aroma-generating substrate was exactly the same except that it did not contain paraffin wax, and two types of heated aroma cartridges were produced in the same manner as in Example 1, except that the crushed aroma source material produced in the drying/killing step (A-1) and crushing step (A-2) of the aroma source material was added to the mixing step (D-1) of the heated aroma-generating substrate production step (D). Then, sensory tests were performed in the same manner as in Example 1.

As a result, more than 8 out of 10 subjects said that, for both heated aroma cartridges, Example 1 produced stronger smoke and aroma and was more pleasant to smoke than the Comparative Example. As is clear from this, the effect of distributing the aroma source material unevenly in the thermally melting substance was confirmed. Hereinafter, if this standard was satisfied, it was deemed to have passed.
Example 2

A heated aroma generating source and a heated aroma cartridge were manufactured in the same manner as in Example 1, except that a heated aroma generating substrate was manufactured by the manufacturing method of Fig. 1-II using the same composition as in Example 1. The manufacturing method of Fig. 1-II includes crushing an aroma source material, crushing a heat-melting substance,
The characteristic of this embodiment is that the aromatic heat-melting powder containing the aromatic source material and the aromatic is produced by mixing the aromatic source material and the aromatic, and the compression and shearing step (D-2) was carried out at a temperature below the melting point of the paraffin wax, as in Example 1. As a result of the sensory test, as in Example 1, the product passed the test, but in this case,
All ten subjects reported that the smoke and aroma were stronger and more pleasant to smoke than the comparative example, demonstrating the effect of distributing the aromatic agent unevenly in the thermally fusible substance.
Example 3

A heated aroma generating source and a heated aroma cartridge were manufactured in the same manner as in Example 1, except that a heated aroma generating substrate was manufactured by the manufacturing method of Fig. 1-III using exactly the same composition as in Example 1. The manufacturing method of Fig. 1-III is characterized in that the aroma is mixed at or above the melting point of the heat-melting substance, and solves the operational problems involved in mixing the aroma with the heat-melting substance. In this case, the compression/shearing step (D-2) was performed below the melting point of the paraffin wax, as in Example 1. The results of the sensory test were the same as in Example 2, and were acceptable.
Example 4

A heated aroma generating source and a heated aroma cartridge were manufactured in the same manner as in Example 1, except that a heated aroma emitting substrate was manufactured by the manufacturing method of Figure 1-IV using the same composition as in Example 1. The manufacturing method of Figure 1-IV includes the following steps in the heated aroma emitting substrate manufacturing step:
A slurry production process (D'-1) and a cast processing process (D'-2) using a paper manufacturing process
The method is characterized by the application of the slurry production process (D'-1) and the cast processing process (D'-2), which were carried out at a temperature below the melting point of the paraffin wax, as was the compression and shear process (D-2). This production method also gave the same sensory test results as those of Example 2.

The effects based on the characteristics of the heated aroma-generating substrate of the present invention have been specifically described above, and next, the heated aroma-generating source of the present invention using this heated aroma-generating substrate and the heated aroma cartridge using this heated aroma-generating source will be described in detail with reference to the drawings. However, the present invention is not limited to these, and various modifications can be made within the scope of the present invention, and the present invention is limited only by the technical ideas described in the claims.

As shown in each of (b) of Figures 3-IA to 3-III-C, the heated aroma source 110 is:
At least an assembly 1121 of the heated aroma generating substrates 112 manufactured in Examples 1 to 4 is sufficient. In this embodiment, the heated aroma cartridge exterior member, which is the cylindrical body of the heated aroma cartridge, i.e., the heated aroma cartridge wrapping member 101, which is a cylindrical scroll,
A heated aroma cartridge housing member 102 which is a cylindrical housing, and a heated aroma cartridge connecting member 103 which is a cylindrical housing which is detachably connected at at least one point
The heated aroma cartridge exterior members will be described in detail later in the heated aroma cartridge.

3-IA to 3-III-C (a), the heated aroma generating source 110 may be formed by wrapping an assembly 1121 of heated aroma generating substrates 112 produced in Examples 1 to 4 in a cylindrical roll of heated aroma generating substrate wrapping member 111. The material of this heated aroma generating substrate wrapping member 111 is not particularly limited as long as it can be made into a cylindrical roll, but in this embodiment, thin paper and plastic film are exemplified.

The shape of the heated aroma generating substrate 112 constituting the heated aroma generating source 110 is not particularly limited and may be sheet-like, cylindrical, prismatic, granular, scaly, etc., but a cylindrical or prismatic shape is preferable from the viewpoint of ensuring a flow path for the aroma and smoke. In this embodiment, for example, as shown in the cross-sectional schematic diagram of the heated aroma generating source 110 in which an assembly 1121 of heated aroma generating substrates 112 is wrapped with a heated aroma generating substrate wrapping member 111 in FIG. 4, a rectangular prism-shaped heated aroma generating substrate 112 is used as the heated aroma generating substrate 112.
As is clear from the figure, the aggregate 1121 of the heated aroma-generating substrates 112 is formed into a large number of heated aroma-generating substrate aggregates 112A, so that the aggregates 112
A primary aggregate flow path 112B is created by the misalignment of the heated aroma-generating substrate 112 in the agglomerate 11
2A, and a substrate-wrapping member gas flow path 112D, which is the space between the heated aroma-generating substrate 112 and the heated aroma-generating substrate-wrapping member 111, are generated, so that volatile matter generated by heating passes through these gas flow paths, allowing the smoker to inhale aroma and smoke with a stable airflow.
The shape may be a sheet, a cylinder, a prism, a granule, or a scale.

As embodiments of the heated aroma cartridge of the present invention using such a heated aroma generating source 110, the following three types of heated aroma cartridges 100 are exemplified. First, as shown in Fig. 2-I, the heated aroma generating source 110 is wrapped in a heated aroma cartridge wrapping member 101, which is a cylindrical scroll, and a mouthpiece 120 is formed, thereby forming a wrapped type heated aroma cartridge 100-I in a smokable form. Second, as shown in Fig. 2-II, the heated aroma generating source 11
2-III-1, the heated aroma generating source 110 is wrapped in a heated aroma cartridge housing member 102, which is a cylindrical housing, and a mouthpiece 120 is formed, thereby forming a housing-type heated aroma cartridge 100-II in a smokable form. Thirdly, as shown in FIG. 2-III-1, a heated aroma generating source connecting part 1031 having a female fitting screw 10311 for the heated aroma generating source connecting part in which the heated aroma generating source 110 is inserted, and a mouthpiece connecting part 1032 having a male screw for the mouthpiece connecting part, which becomes the mouthpiece 120, are detachably connected to form a heated aroma cartridge connecting member 103, which is a cylindrical housing.
The connecting type heated aroma cartridge 100-III is a heated aroma cartridge configured in a smokable form.

In particular, as shown in FIG. 2-III-1, the heated aroma generating source connecting part 1031 and the mouthpiece connecting part 1032 constituting the heated aroma cartridge connecting member 103 of the connecting type heated aroma cartridge 100-III are detachable, so that the heated aroma generating source 110 and various mouthpieces 120 described later can be freely replaced according to the smoker's preference.
1 and the mouthpiece connecting part 1032 can be easily cleaned and can be reused.

The heated aroma cartridge of the present invention includes the following components:
The mouthpiece 120 shown in I-1 is a feature of the heated smoking device 200 .
The smoke produced by smoking a heated aroma cartridge using the above is based on the aerosol generated by the aerosol former volatilizing and then cooling, and does not contain any solid components like cigarettes, and contains little or no tobacco plant material in the aroma source material, so it contains little nicotine or tar, and does not require a filter function in the mouthpiece. At least a cooling function is required to condense the volatile components of the aerosol into aerosol, so the wrapping type heated aroma cartridge 100-I and the housing type heated aroma cartridge 100-II shown in Figures 2-I, 2-II, and 2-III-1 are used.
, and the mouthpiece 120 of the connecting type heated aroma cartridge 100-III
4 shows an embodiment which is hollow.

In this case, because the heated aroma cartridge wrapping member 101 is held in the mouth, paper cannot be used, and in this embodiment, a polyolefin-based resin film is used as an example. The heated aroma cartridge housing member 102 and the connecting member 103 are also made of polyolefin-based resin, and a molded housing is used as an example. The materials of the heated aroma cartridge housing members and connecting members are the same as in the following examples.

However, the wrapping type heated aroma cartridge 100-IA and the housing type heated aroma cartridge 100-II shown in Figs. 3-IA, 3-II-A, and 3-III-A are not shown.
As shown in the connecting type heated aroma cartridge 100-III-A and the connecting type heated aroma cartridge 100-III-A, the mouthpiece can be provided with a filter member 122 according to the cigarette smoker's habits. In particular, in this case, the heated aroma cartridge wrapping member 101 of the wrapping type heated aroma cartridge 100-IA is preferably made of wrapping paper similar to that of a cigarette,
In this embodiment, a case where a wrapping paper is used is illustrated. As is clear from the figure, in each of the heated aroma cartridges, the filter member 122 is a mouthpiece wrapping member 1
As shown in the example of the filter mouthpiece 120-A1 wound with the filter member 122 and the filter mouthpiece 120-A2 in which the filter member 122 is directly inserted into the exterior member of the heated aroma cartridge, either one is acceptable, but the housing type heated aroma cartridge 100
In the case of the connecting type heated aroma cartridge 100- II-A and the connecting type heated aroma cartridge 100-III-A , since the filter mouthpieces 120-A1 and A2 are detachable, it is preferable that they are wrapped with the mouthpiece wrapping member 121. In addition, in this embodiment, taking into consideration the resistance to the aerosol former, a mouthpiece wrapping member 121 made of a thin polyolefin resin film is exemplified. The same applies below.

3-IA(b), 3-II-A(b), and 3-III-A(b) show that each heated aroma cartridge 10 is provided with meshes 1011, 1021, and 10312 for preventing the heated aroma-generating substrate, debris of the heated aroma-generating substrate, and dust generated by the debris from falling off and scattering from the heated aroma-generating source 110 to the filter member 122.
0-IA(b) , 100-II-A(b) , and 100-III-A(b) are shown as examples. The meshes 1011 and 1021 of this embodiment are shown as examples of nonwoven fabrics made of polyester-based resin fibers.

Here, in the case of the connecting type heated aroma cartridge 100-III-A(b) ,
As shown in FIG. 2-III-2(b), the mesh 10312 can be detachably attached to the heated aroma source connecting portion 1031B.
The heated aroma emitting source connecting part 1031B to which the heated aroma emitting source 1312 is attached not only prevents the heated aroma emitting source 1312 from falling off and scattering, but also prevents the heated aroma emitting source 1312 from falling off and scattering.
The mesh 10312 can be inserted without protruding, the amount of the mesh 10312 can be adjusted, and the mesh 10312 can be cleaned. Although the mesh 10312 can be provided with a nonwoven fabric made of polyester-based resin fiber, the present embodiment illustrates a woven fabric made of polyester-based resin fiber that has excellent strength for repeated use.

Further, the heated aroma cartridge 100 having a support member 123 for preventing the heated aroma generating source 110 from moving toward the filter member 122 is shown in 100-IB, 100 -II-B , and 100-III -B in Figs . 3-IB , 3-II-B, and 3-III-B.
In this case, similarly to mouthpieces 120-A1 and 120-A2 each having only a filter member 122, mouthpieces 120-B1 and 120-B2 each having a mouthpiece wrapping member 121 and no mouthpiece wrapping member 121 are shown.

In this embodiment, FIG. 3-IB(b), FIG. 3-II-B(b), and FIG.
As shown in B(b), an example of a heated aroma cartridge 100 is shown which, in addition to meshes 1011, 1021, 10312 for preventing the heated aroma-generating substrate, debris from the heated aroma-generating substrate, and dust generated by the debris from falling off and scattering from the heated aroma-generating source 110 to the filter member 122 , also includes covers 1012, 1022, 10313 for preventing the heated aroma-generating substrate, debris from the heated aroma-generating substrate, and dust generated by the debris from falling off and scattering from the heated aroma-generating source 110 to the chamber 202 of the heated smoking device 200 . Since the heat source 203 of the heated smoking device 200 shown in Figure 6 penetrates these and comes into slight contact with the heat source 203, it is preferable that the covers be nonwoven or woven fabric made of vegetable fibers so as not to soil the heat source 203, and nonwoven fabric is exemplified for the covers 1012 and 1022.

In this case, the connecting type heated aroma cartridge 100-III-B(b) has a heated aroma source connecting part 1031C to which a cover 10313 is detachably attached, as shown in Figure 2-III-2(c), and can be used repeatedly. However, since the heat source 203 must be inserted when using it for the first time, it is preferable that the heat source be a nonwoven fabric made of vegetable fibers, and in this embodiment, a nonwoven fabric made of vegetable fibers is exemplified.

A cooling member 12 for cooling the volatile matter of the aerosol former and promoting the generation of smoke.
The heated aroma cartridge 100 having the 4 is shown in FIGS. 3-IC, 3-II-C, and 3
-III-C, 100-IC , 100-II-C , and 100-III-C .
In this case, similarly to mouthpieces 120-A1 and 120-A2 each having only a filter member 122, mouthpieces 120-B1 and 120-B2 corresponding to the presence or absence of a mouthpiece wrapping member 121 are illustrated.

In this embodiment, FIG. 3-IB(b), FIG. 3-II-B(b), and FIG.
As in the case of FIG. 1B(b), in addition to meshes 1011, 1021, 10312 for preventing the heated aroma-emitting substrate, the collapsed material of the heated aroma-emitting substrate, and the dust generated by the collapsed material from falling off and scattering from the heated aroma-emitting source 110 to the filter member 122,
1. A cover 1 for preventing the falling and scattering of the heated aroma-generating substrate, the collapsed material of the heated aroma-generating substrate, and the dust generated by the collapsed material from the heating device 100 to the chamber 202 of the heated smoking device 200.
Illustrated is a heated aroma cartridge 100 equipped with 013, 1023, and 10314.
However, these covers 1013, 1023, and 10314 are not included in the heated smoking device shown in FIG.
Since heat source insertion holes 10131, 10231, 103141 through which heat source 203 of 200 is inserted are provided, these covers 1013, 1023, 10314 do not come into contact with heat source 203. Therefore, heat source 203 can be easily inserted into heated aroma source 110, and covers 1013, 1023, 10314 are not heated and contaminated by heat source 203. Therefore, nonwoven fabric or woven fabric made of plastic fiber can be used as the material for covers 1013, 1023, 10314, and in this embodiment, nonwoven fabric or woven fabric made of polyester fiber is exemplified.

In this case, the connecting type heated aroma cartridge 100-III-C(b) is a heated aroma source connecting part 1031D to which a cover 10314 is detachably attached as shown in FIG. 2-III-2(d), and can be used repeatedly.
Since the heat source insertion hole 103141 through which the heat source is inserted is provided, taking repeated use into consideration, it is preferable that the heat source be a woven fabric made of polyester fiber, and in this embodiment, a woven fabric made of polyester fiber is exemplified.

The above are examples of embodiments of the heated aroma generating source 110, the mouthpiece 120, and the heated aroma cartridge in which the heated aroma generating source 110 and the mouthpiece 120 are wrapped around the heated aroma cartridge exterior material, the heated aroma cartridge wrapping member 101, the heated aroma cartridge housing member 102, and the heated aroma cartridge connecting member 103, but the present invention is not limited to these. The heated aroma generating source and heated aroma cartridge of the present invention can be implemented in various modifications within the scope of the present invention, and are limited only by the technical ideas described in the claims.

The present invention is a technology that can provide the enjoyment of smoking smoke and aroma derived from plants including tobacco, which is a member of the Solanaceae family. When tobacco plants are not included, the smoker can enjoy smoking without adversely affecting the health of not only the smoker but also the surrounding non-smokers, and it is a new smoking tool that brings about alpha waves in the brain, has a healing effect, and is useful for promoting health and beauty. Therefore, the technology of the present invention for promoting the generation of smoke and aroma related to the heated aroma-generating substrate can be applied to incense sticks, burning incense, powdered incense, incense linings, etc., which are similar to the heated aroma-generating substrate, as well as aromatherapy, etc.
