DESCRIPTION OF PERFORMANCE OPTIONS

[0008] Embodiments of the present invention will now be described with reference to the drawings. Identical reference numerals in the drawings denote the same or corresponding components as described below, but such components will not be described again.

[0009] FIG. 1 is a schematic side view of an aroma inhaler according to the present embodiment. The flavor inhaler 100 according to the present embodiment is designed to generate aerosols containing a aroma substance by heating the aerosol source and the aroma source. As shown in the drawing, the aroma inhaler 100 includes a first body 110, a second body 120, and a mouthpiece 130. The first body 110 and the second body 120 can be configured to be attached to and detached from each other. Here, the expression "capable of being attached to and detached from" includes not only the case in which the first body 110 and the second body 120 are completely separated from each other, but also the case where the first body 110 and the second body 120 are partially connected by a hinge or similar element, as described below. The mouthpiece 130 may be attached/detachable connected to one end of the second body 120 or may be integrally formed with the second body 120.

[0010] FIG. 2 is a schematic view of one example of an aromatic inhaler 100. As illustrated, the aromatic inhaler 100 includes a battery 140 that is located inside the first housing 110, a heating portion 150, a control circuit 170, and a cooling portion 160 located inside the second housing 120. As depicted in 1, the first body 110 and the second body 120 are connected to each other in a rotatable manner by means of a hinge. The first housing 110 and the second housing 120 can be connected to each other in such a way that they can be completely separated from each other, for example, connected by snapping, screwing or the like. Thus, the cooling portion 160, the mouthpiece 130, and the heating portion 150 can be easily cleaned by completely separating the first housing 110 and the second housing 120 from each other.

[0011] The battery 140 is configured to supply electrical power to the heating portion 150, the control circuit 170, and the like. For example, battery 140 is a lithium ion battery. Battery 140 may be charged from an external power source. The cooling portion 160 is designed to cool the aerosols generated in the cartridge 10. The cooling portion 160 may be a space in which the aerosols passing through are cooled, for example, naturally. Alternatively, one or more materials selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate and aluminum foil may be located in or fill the cooling portion 160. By placing these materials in or filling the cooling portion 160, it is possible to provide more efficient cooling of the aerosols.

[0012] In the illustrated example, the heating portion 150 includes heating plates 150a that are inserted into the cartridge 10. In other words, the heating portion 150 is an internal type heater that heats the cartridge 10 from within the cartridge. The heating plates 150a include substrates made of, for example, resin, where heat conductive paths are formed on the surfaces of the substrates, and the thickness of the heating plates may be, for example, about 0.5 mm. Moreover, in the illustrated example, the heating portion 150 includes two heating plates 150a. In the aroma inhaler 100, one cartridge 10 may be attached to any of the heating plates 150a, or two cartridges 10 may be attached to the heating plates 150a, respectively. In this way, the amount of aerosols produced from the cartridge 10 can be controlled. The aroma inhaler 100 may include one or two or more heating plates 150a. For example, the heating portion 150 is configured to heat the cartridge 10 to a temperature equal to or greater than 200°C and equal to or less than 300°C.

[0013] The control circuit 170 is composed of a central processing unit, a memory, and the like, and controls the operation of the aroma inhaler 100. For example, the control circuit 170 initiates the heating process of the cartridge 10 in response to user action on an input device such as a push button or slide switch, which is not shown in the drawing, and completes heating of the cartridge 10 after a certain period of time. The control circuit 170 may stop heating the cartridge 10 even before a certain period of time has elapsed from the start of heating the cartridge 10 if the number of times the user puffs exceeds a certain value. For example, a tightening event is detected by a sensor not shown in the drawing.

[0014] Alternatively, control circuit 170 may start heating the cartridge 10 in response to the start of puffs and stop heating the cartridge 10 in response to the end of puffs. The control circuit 170 may stop heating the cartridge 10 even before the puffs are completed, if a certain period of time has elapsed since the puffs began. In the illustrated example, control circuit 170 is located between battery 140 and heating portion 150, and limits the transfer of heat from said portion 150 to battery 140.

[0015] The cartridge 10 is heated by the heating portion 150 and thereby generates vapor and aerosols from the aerosol source or aroma source. The vapor and aerosols generated in the cartridge 10 are cooled by passing through the cooling portion 160 and reach the user's oral cavity through the mouthpiece 130 by being sucked by the user. The steam generated in the cartridge 10 is cooled by the cooling portion 160 and can be sprayed into aerosols. In the present embodiment, the cartridge 10 is in the form of a thin plate or card. The cartridge 10 is positioned such that a portion thereof protrudes from the first body 110 in a state in which the heating plate 150a of the heating portion 150 is inserted into the said cartridge. Thus, the user can easily detach the cartridge 10 from the heating plate 150a after use.

[0016] FIG. 3 is a schematic view of another example of the aroma inhaler 100. The aroma inhaler 100 shown in FIG. 3 is different from the aroma inhaler 100 shown in FIG. 2, by the configuration of the heating portion 150. Specifically, the heating portion 150 includes an induction coil 150b for inductively heating the current collector. The susceptor may be located in the aroma inhaler 100 or in the cartridge 10. For example, the aroma inhaler 100 may include a susceptor that is intended to fit into the cartridge 10 when said cartridge is located in the heating portion 150. Alternatively, the cartridge 10 may contain a metallic material that is inductively heated by the induction coil 150b. It should be noted that the aroma inhaler 100 illustrated in FIG. 3 may include an electromagnetic shield (not shown in the drawing) located between the heating portion 150 and the control circuit 170 to prevent an electromagnetic wave generated by the induction coil 150b from entering the control circuit 170.

[0017] Next, details of the cartridge 10 will be described. In FIG. 4 is a perspective view of a cartridge 10. The cartridge 10 contains a feed part 30, which is heated and thereby generates aerosols, and a shell 20 in which said part 30 is located. The cartridge 10 shown in FIG. 4 does not contain a mouthpiece or filter and a cooling part, but only contains a raw material part 30. In other words, since the cartridge 10 has a simple configuration, it can be easily produced continuously and the waste mass of the cartridge after use can be comparatively reduced. In addition, since the cartridge 10 does not need to provide a cooling function and a filtration function, freedom of choice in designing the cooling portion 160 and the mouthpiece 130 (or filter) in the aroma inhaler 100 is increased. In particular, the cooling function can be easily improved by providing an increase in the surface area of the cooling portions 160 of the aroma inhaler 100 to aid heat dissipation.

[0018] The shell 20 has a flattened, substantially tubular shape and includes a first wall 20a, a second wall 20b, and a pair of connecting walls 20c. The first wall 20a is a wall containing the largest plane of the shell 20. The second wall 20b faces the first wall 20a. A pair of connecting walls 20c connects the first wall 20a to the second wall 20b. Specifically, one of the connecting walls 20c extends between one end of the first wall 20a and one end of the second wall 20b, and the other of the connecting walls 20c extends between the other end of the first wall 20a and the other end of the second wall 20b. Thus, a substantially tubular shell 20 is formed by a first wall 20a, a second wall 20b, and a pair of connecting walls 20c, and one or more air flow paths through which aerosols pass are provided within the shell 20, as will be described later.

[0019] In addition, the shell 20 has a first hole 21, a second hole 22 facing the first hole 21, a first end surface 21a formed with the first hole 21, and a second end surface 22a formed with the second hole 22. The first hole 21 and the second opening 22 is formed by a first wall 20a, a second wall 20b, and a pair of connecting walls 20c. The heating plate 150a of the heating portion 150 or the current collector of the above-described aroma inhaler 100 may be inserted into the second opening 22. Aerosols directed from the feed portion 30 to the cooling portion 160 may pass through the first opening 21. The first opening 21 and the second opening 22 may each have essentially the same shape.

[0020] The thickness of the shell 20 (the length between the outer side surface of the first wall 20a and the outer side surface of the second wall 20b) can be, for example, from about 1.5 mm to 4 mm. The length of the shell 20 (the length between the first end surface 21a and the second end surface 22a) is, for example, approximately 18 mm to 25 mm. The width of the shell 20 (length perpendicular to the thickness direction and length direction) is, for example, about 12 mm. The shell 20 can be made, for example, from special cardboard. In particular, the shell 20 can be made, for example, of paper with a density equal to or greater than 100 g/m ² and equal to or less than 300 g/m ² .

[0021] Since the raw material part 30 is located in the shell 20, the cartridge 10 can be removed from the heating part 150 without the user directly touching the raw material part 30, which is at a high temperature after use. In addition, by being housed in the shell 20, it is possible to maintain the shape of the raw material portion 30, which is relatively easy to deform, and easily maintain a constant size of the first gap 33 or the second gap 34 formed in the portion 30 and described later. Moreover, it is possible to ensure that some of the vapor or aerosols generated from the raw material part 30 is absorbed by the shell 20 made of paper, and the vapor or aerosols are prevented from condensing inside the aroma inhaler 100.

[0022] A metal foil, such as aluminum, may be located on the inner surface of the shell 20. In this way, it is possible to limit heat dissipation due to heat transfer between the heating portion 150 and the raw material portion 30 heated by the portion 150, and ensure efficient heating of the portion 30.

[0023] The raw material portion 30 made according to the present embodiment includes a web having fold lines. Fig. 5 is an enlarged cross-sectional view of a portion of a raw material portion 30. As shown in the drawing, the raw material portion 30 includes a base material layer 31 and a raw material layer 32. The base material layer 31 and the raw material layer 32 are superimposed on each other. In the present embodiment, the base material layer 31 is a metal-bonded paper formed by a metal layer 31a composed of aluminum, stainless steel or the like and a paper layer 31b bonded to each other. By using the base material layer 31 containing the metal layer 31a, heat from the heating plate 150a of the heating portion 150 to the raw material layer 32 can be efficiently transferred. In addition, in the case where the base material layer 31 includes a metal layer 31a, the metal layer can also be used as a current collector. In one embodiment, the base material layer 31 may be paper that does not have a metal layer 31a. In particular, the base material layer 31 may be made of only a layer of cellulose paper or the like. The thickness of the metal layer 31a is equal to or greater than 5 μm and is 30 μm or less, for example, in the case where the metal is aluminum, and if the amount of metal used is reduced and heat transfer is taken into account, the preferred thickness is equal to or greater than 5 μm and is 15 μm or less and , in particular, can be about 10 µm.

[0024] The raw material layer 32 is not attached to the base material layer 31 using an adhesive such as glue, but is formed integrally with said layer 31 by overlapping. Although the raw material layer 32 may be attached to the base material layer 31 using an adhesive such as glue, attachment without any adhesive is preferable from the standpoint of smoking taste and ease of manufacturing of the raw material portion 30. The raw material layer 32 may be tobacco. a web containing, for example, tobacco (corresponding to a sample from a flavor source), a polyhydric alcohol (corresponding to a sample from an aerosol source), and the like. Polyhydric alcohol may contain glycerin, propylene glycol, sorbitol, xylitol and erythritol. For the feed layer 32, only one of these polyhydric alcohols may be used, or two or more types thereof may be used in combination. In particular, the raw material layer 32 may be formed by mixing a binder with powdered tobacco and polyhydric alcohol, applying the mixture to the paper layer 31b of the base material layer 31 and then evaporating part of its moisture. As the binder, for example, guar gum, xanthan gum, carboxymethylcellulose (CMC), sodium carboxymethylcellulose (CMC-Na), pullulan and hydroxypropylcellulose (HPC), methylcellulose or hydroxylmethylcellulose can be used.

[0025] In addition, cellulose may be added to the raw material layer 32. Cellulose can increase the strength of the raw material layer 32. However, cellulose may not be added to the raw material layer 32 unless there is a need to improve the strength of said layer, for example, in the case where the raw material portion 30 contains a base material layer 31, as in this embodiment. If cellulose is not used, the proportion of tobacco in the raw material layer 32 increases by a corresponding amount and, thus, the taste of the smoke is expected to improve.

[0026] Although a binder may be added to the raw material layer 32 to control proper application of the raw materials, the binder may not be added. For example, the percentage by weight of binder that may be added to the raw material layer 32 is preferably from 0% to 60% inclusive, and more preferably from 0% to 10% inclusive, based on the weight of said layer.

[0027] For example, the feed layer 32 may have the following blend ratios (in percent by weight): 5% to 40% polyhydric alcohol, 50% to 90% tobacco, 0% to 10% binder, and 0 % to 10% cellulose. In addition, an acid such as lactic acid, palmitic acid, or benzoic acid may be added to the feed layer 32.

[0028] Moreover, with regard to manufacturing, the raw material portion 30 preferably has a tensile strength equal to or greater than 3 N/15 mm, more preferably equal to or greater than 5 N/15 mm, and even more preferably equal to or greater than 10 N/15 mm. It should be noted that the tensile strength of the raw material portion 30 can be measured by performing a dry tensile strength test (ISO 1924-2) performed on a 250 mm x 15 mm test piece. The raw material portion 30 can be easily bent if the portion is manufactured in the following manner, and the raw material portion 30 can be easily prevented from breaking if it has the above tensile strength.

[0029] Even if the base material layer 31 does not contain the paper layer 31b, the types and speeds of mixing the raw materials can be selected so that the raw material layer 32 can be applied to the metal layer 31a of the base material layer 31. On the other hand, the ability to attach the raw material layer 32 to the base material layer 31 can be improved if said layer 31 includes a paper layer 31b as described above. In particular, proper application and adhesion of the raw material layer 32 to the base material layer 31 can be improved if said layer 31 includes a paper layer 31b. It is believed that the reason for this is that the affinity between the paper layer 31b and the raw materials is high, and the adhesion is enhanced because the raw materials become entangled with fine cellulose irregularities present on the surface of the paper layer 31b. In addition, the paper layer 31b functions as an absorbent material during drying and can provide flexibility to the raw material portion 30 including the raw material layer 32 and the base material layer 31.

[0030] In addition, the raw material layer 32 may be a non-tobacco web containing, for example, an aerosol source as well as the aforementioned tobacco web. Non-tobacco web means non-tobacco material formed in the form of a sheet and may contain tobacco material. In particular, the feed layer 32 may comprise a non-tobacco fiber, such as cellulose fiber or nonwoven material, and an aerosol source. The non-tobacco fiber used for the non-tobacco web may contain non-cellulose fiber. Non-cellulose fiber is a fiber other than cellulose fiber. Cellulose fiber is a group of cellulose fibers extracted from plant material such as wood material and commonly used as raw material for paper. Examples of cellulose fiber include waste paper pulp, chemical pulp, wood pulp and the like.

[0031] The non-tobacco web may contain a binder. A binder is an adhesive that binds fiber and similar materials. As a binder, a binder known in the art can be used. The non-tobacco fabric may contain an emulsifier. The emulsifier enhances the affinity between the lipophilic aerosol-forming base material and the hydrophilic non-valved fiber. A known emulsifier can be used, examples of which contain an emulsifier whose hydrophilic-lipophilic balance (HLB) value is 8-18.

[0032] An aerosol source is a material that gasifies when heated, then cools and thereby forms aerosols, or a material that forms aerosols when sprayed. A known aerosol source may be used, examples of which include polyhydric alcohols such as glycerin and propylene glycol (PG), triethyl citrate (TEC) and triacetin. An aerosol source may also be added to the raw material layer 32 of the aforementioned tobacco web.

[0033] The non-tobacco web may contain a flavor-generating base material. The aroma generating base material is a material that provides the aroma and flavor of smoke, and is preferably a tobacco material. Specific examples of the tobacco material include dried chopped tobacco leaves, ground leaf tobacco, and tobacco extract (an extract obtained using water, an organic solvent, or a mixture thereof). Ground leaf tobacco means shreds obtained by grinding leaf tobacco. The average particle diameter of the ground leaf tobacco may be, for example, from 30 µm to 120 µm. Grinding can be done using a known mill and can be dry or wet. Thus, ground leaf tobacco is also called leaf tobacco crumb. In the present embodiment, the average diameter of the particles is determined by laser diffraction scattering method, and in particular, said size is measured using a laser diffraction particle diameter distribution measuring device (for example, LA-950 laser analyzer manufactured by Horiba Ltd.) . In addition, the type of tobacco is not limited, and cultivated varieties can be used: yellow, burley, oriental, local, as well as other varieties such as "Nicotiana tabacum" or "Nicotiana rustica". Although the amount of the aroma generating base material in the non-tobacco web is not particularly limited, the amount is preferably from 1% by weight to 30% by weight, and more preferably from 10% by weight to 20% by weight.

[0034] The non-tobacco web may contain a flavoring agent. A flavoring is a substance that imparts aroma and taste. The flavoring can be natural or synthetic. One type or a mixture of several types of flavorings can be used as a flavoring agent. As the flavoring agent, any flavoring agent commonly used in a smoking article may be used, and specific examples thereof will be described below. The flavoring agent may be contained in the non-tobacco web in such an amount that the smoking article can provide an appropriate aroma and taste, and, for example, the amount of said flavoring in the non-tobacco web is preferably from 1% by weight to 30% by weight, and more preferably from 10% by weight up to 20% by weight.

[0035] The flavoring agent can be any commonly used flavoring agent, such as, for example, an essential oil, natural or synthetic. In addition, the flavoring agent may be liquid or solid, and may be of any type. Suitable examples of flavoring agents include tobacco extracts and tobacco components, sugar and sugar-based flavorings, licorice, cocoa, chocolate, fruit juices and fruits, spices, European liqueurs, herbs, vanilla, flavoring selected from floral flavors, and combinations thereof. Specific examples contain a flavoring agent selected from isothiocyanates, indole and its derivatives, ethers, esters, ketones, fatty acids, higher aliphatic alcohols, higher aliphatic aldehydes, higher aliphatic hydrocarbons, thioesters, thiols, terpene-based hydrocarbons, phenolic esters, phenols , furfural and its derivatives, aromatic alcohols, aromatic aldehydes, lactones, etc., or combinations thereof.

[0039] In addition, the non-tobacco web may contain a refreshing additive or seasoning. The type of refreshing additive is not particularly limited, and from the viewpoint of imparting a corresponding taste when smoking, examples of the additive include menthol, camphor, isopulegol, cineole, peppermint oil, peppermint oil, eucalyptus oil, 2-1-mentoxyethanol (COOLACT (registered trademark) 5 ), 3-1-menthoxypropane-1,2-diol (COOLACT (registered trademark) 10), 1-menthyl-3-hydroxybutyrate (COOLACT (registered trademark) 20), p-menthane-3,8-diol ( COOLACT (registered trademark) 38D), N-(2-hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide (COOLACT (registered trademark) 370), N-(4-( cyanomethyl)phenyl)-2-isopropyl-5,5-dimethylcyclohexanecarboxamide (COOLACT (registered trademark) 400), N-(3-hydroxy-4-methoxyphenyl)-2-isopropyl-5,5-dimethylcyclohexanecarboxamide, N-ethyl- p-menthane-3-urea (WS-3), ethyl 2-(p-menthane-3-carboxamide) acetate (WS-5), N-(4-methoxyphenyl)-p-menthanecarboxamide (WS-12), 2-isopropyl-N,2,3-trimethylbutylamide (WS-23), 3-1-mentoxy-2-methylpropane-1,2-diol, 2-1-mentoxyethan-1-ol, 3-1-mentoxypropan-1 -ol, 4-1-mentoxybutan-1-ol, menthyl lactate (FEMA3748), menthone glycerol acetal (FrescolatMGA, FEMA3807, FEMA3808), 2-(2-1-menthyloxyethyl)ethanol, menthyl glyoxylate, 2-pyrrolidone-5- menthyl carboxylate, menthyl succinate (FEMA3810), N-(2-(pyridin-2-yl)-ethyl)-3-p-methnanocarboxamide (FEMA4549), N-(ethoxycarbonylmethyl)-p-menthan-3-carboxamide, N- (4-cyanomethylphenyl)-p-menthanocarboxamide and N-(4-aminocarbonylphenyl)-p-menthane. Only one refreshing additive may be used, or two or more types may be used together.

[0040] The type of seasoning is not particularly limited, and from the point of view of imparting a corresponding taste when smoking, examples of the seasoning contain sweeteners (sugar (glucose, fructose, isomerized sugar, caramel and the like)), acidifiers (organic acids and the like) and other flavoring agents components (materials with exquisite taste, bitter taste, salty taste and the like). In addition, a fatty component (wax, waxy material, fatty acids (short-chain, medium-chain and long-chain fatty acids and the like) can be added as an option).

[0041] Although in one aspect the total content of flavoring, flavoring and seasoning is not particularly limited, in case they are contained in shredded tobacco and from the viewpoint of imparting a suitable smoking taste, the total content is generally 10,000 ppm or more, preferably 20,000 ppm or more, more preferably 25,000 ppm or more, and also typically 70,000 ppm or less, preferably 50,000 ppm or less, more preferably 40,000 ppm or less, and even more preferably 33,000 or less parts per million. Moreover, according to another aspect, the total amount is preferably equal to or greater than 2% by weight, more preferably equal to or greater than 5% by weight, and preferably 20% by weight or less, and more preferably 10% by weight or less.

[0042] In FIG. 6 schematically illustrates an example of the raw material portion 30 in cross-section and with the said portion positioned in the shell 20. In the illustrated example, the raw material portion 30 has three fold lines, namely, F1, F2 and F3. Specifically, the raw material portion 30 is folded along fold line F1 and fold line F2 so that the raw material layer 32 faces itself, and along line F3 is folded so that the base material layer 31 faces itself. Thus, the raw material portion 30 has first gaps 33 formed by the raw material layer 32 facing toward itself and a second gap 34 formed by the base material layer 31 facing toward itself. In other words, it is possible to form the first gaps 33 and the second gap 34 by bending the raw material portion 30 of the web along the fold lines F1, F2 and F3 without forming a full contact of the web by using the reaction force caused by the plastic deformation of the metal layer 31a of the layer 31 base material, and the reaction force caused by elastic deformation due to folding of the paper layer 31b interacting with each other and maintaining mutual balance. It should be noted that even in the case that the base material layer 31 is formed only of the metal layer 31a or the paper layer 31b, the first gaps 33 and the second gap 34 can also be formed without forming a complete tight contact of the web due to the force generated in the metal layer 31a and supporting the shape caused by plastic deformation or the reaction force caused by elastic deformation resulting from folding of the paper layer 31b. In the illustrated example, the raw material portion 30 has a pair of first gaps 33, between which a second gap 34 is located. Thus, it is possible to provide substantially uniform heating of the raw material layer 32 located on both sides of the second gap 34 by means of a heating plate 150a or a current collector located in the specified gap 34, and as a result uniformize the aerosols generated from the first pair of gaps 33.

[0043] FIG. 7 is another schematic example of the raw material portion 30, in cross-section and positioning the said portion in the shell 20. In the illustrated example, the raw material portion 30 has three fold lines, namely, F4, F5 and F6. Specifically, the raw material portion 30 is folded along fold line F4 and fold line F5 so that the raw material layer 32 faces itself, and along line F6 is folded so that the base material layer 31 faces itself. The direction in which the raw material portion 30 shown in FIG. 7 is folded along the folding line F6, opposite to the folding direction along the folding line F3 of the raw material portion 30 shown in FIG. 6. Thus, the raw material portion 30 has first gaps 33 formed by the raw material layer 32 facing toward itself and a second gap 34 formed by the base material layer 31 facing toward itself. In other words, the first gaps 33 and the second gap 34 can be formed without causing the web to be in full contact by folding the web raw material portion 30 along fold lines F4, F5 and F6. In the illustrated example, the raw material portion 30 has a pair of first gaps 33, between which a second gap 34 is located. Thus, it is possible to provide substantially uniform heating of the raw material layer 32 located on both sides of the second gap 34 using a heating plate 150a or a current collector located in the specified gap 34, and as a result uniformize the aerosols generated from the first pair of gaps 33.

[0044] As shown in FIG. 6 and 7, the feedstock portion 30 has first gaps 33 formed by the feedstock layer 32 facing itself, and thereby aerosols generated from said layer can pass through the first gaps 33. In other words, the first gaps 33 can define air flow channels through which aerosols pass. In this way, it is possible to ensure efficient delivery of aerosols generated from the feed layer 32 to the downstream side. In addition, since the raw material portion 30 has a second gap 34 formed by the base material layer 31 facing itself, effective heating of the raw material layer 32 can be achieved by inserting the heating plate 150a of the heating portion 150 or the current collector of the aroma inhaler 100 into the second gap 34 and not driving the plate or pantograph into contact with the layer 32. Thus, contamination of the heating plate 150a or pantograph by the raw material layer 32 is limited, and the frequency of cleaning operations of the heating plate 150a or pantograph can be reduced.

[0045] The raw material portion 30 is not limited to the examples illustrated in FIGS. 6 and 7, and can have any fold lines. In addition, the raw material portion 30 may not have any fold lines, and a flat raw material portion 30 may be disposed in the shell 20. It should be noted that in the case where the heating portion 150 of the aroma inhaler 100 includes an induction coil 150b, the raw material metal layer 31a 30 performs the function of a current collector. In other words, the raw material layer 32 can be heated by the induction coil 150b to inductively heat the metal layer 31a. In this case, the aroma inhaler 100 may not have a current collector.

[0046] In FIG. 8 is a schematic view of another example of a raw material part 30, in cross-section and with said part positioned in the shell 20. The raw material part 30 shown in FIG. 8 has a pair of inner folded portions 30b that are folded along fold line F1 and folded line F2 and located inside said portion, and a pair of outer folded portions 30a that are folded along fold line F3 and located outside of portion 30. It should be noted that in the unfolded state of the raw material part 30, the fold line F3 is located between the fold line F1 and the fold line F2.

[0047] The raw material portion 30 shown in FIG. 8 contains the raw material part 30 shown in FIG. 6, wherein the first gaps 33 of said portion are formed by the raw material layer 32 facing toward itself using similar fold lines, and the second gap 34 is formed by the base material layer 31 facing toward itself. However, the raw material part 30 shown in FIG. 8 is different from the raw material part 30 shown in FIG. 6 in that one portion of the second gap 34 is larger than the other portion of said gap 34 for the purpose of introducing a heating plate 150a or a current collector. Specifically, in the example illustrated in FIG. 8, the size of the second gap 34a between the fold line F1 and the fold line F2 is larger than the size of the second gap 34b between the end portions 30b' on the side of the pair of inner folded portions 30b opposite the fold line F1 or the fold line F2. Thus, the heating plate 150a or current collector easily fits into the relatively large second gap 34a. Therefore, it is possible to prevent the heating plate 150a or the current collector from being inserted into the first gap 33 by mistake.

[0048] The size of the second gap 34a between the fold line F1 and the fold line F2 can be set to be larger than the size of the second gap 34b between the end portions 30b' of the inner folded portions 30b, as shown in FIG. 8 by adjusting the length of said portions 30b. In particular, the length of the outer folded portions 30a (the length from the fold line F1 or fold line F2 to the folded line F3 in the section shown in FIG. 8) can be set, for example, to a value of 10.5 mm, and the length of the inner folded portions 30b ( the length from the fold line F1 or fold line F2 to the end portions 30b' located on the opposite side in the section shown in Fig. 8) can be set, for example, to a value of 9.5 mm. Here, when the raw material portion 30 is folded along the fold line F1, the fold line F2 and the fold line F3, the end portions 30b' of the inner folded portions 30b come into contact with the area near the fold line F3 of the outer folded portions 30a, as shown in the drawing. At this time, each of the inner folded portions 30b experiences a load directed toward the fold line F1 or fold line F2 from the outer folded portions 30a. Thus, each of the inner folded portions 30b is bent to become curved, the fold line F1 and the fold line F2 are separated from each other, and the size of the second gap 34a between the fold line F1 and the fold line F2 is increased.

[0049] Without being limited to this, and in the case in which the raw material part 30 can maintain its shape, for example, through plastic deformation, the said part can be bent so that the size of the second gap 34a between the fold line F1 and the fold line F2 is larger than the size of the second a gap 34b between the end portions 30b' on the side opposite the fold line F1 of the inner folded portions 30b, which is accomplished by adjusting the force generated when bending the raw material portion 30. It should be noted that the length of the raw material portion 30 shown in FIG. 6-8. in a direction orthogonal to the insertion direction of the heating plate 150a (the length in the direction extending from left to right in the drawing), that is, the width of the raw material portion 30 is preferably larger than the width of the heating plate. Alternatively, the length of the raw material portion 30 in the insertion direction of the heating plate 150a (the depth direction of the surface of the drawing paper) is preferably longer than the length of the plate. Thus, a region is formed in the stock portion 30 that does not come into contact with the heating plate 150a, and the heating plate 150a can gradually heat the stock portion 30 so that at a later stage of the smoking process, the tendency of aerosol generation to decrease can be limited.

[0050] Although the raw material portion 30 shown in FIG. 8 is formed by folding, which is similar to the folding of the raw material part 30 shown in FIG. 6, the present invention is not limited to the above. The raw material portion 30 may have any fold lines so that the size of the second gap 34a between the fold lines is larger than the size of the second gap 34b between the end portions 30b' of the inner fold portions 30b.

[0051] In FIG. 9 is a side view of the cartridge 10 as viewed from the side of the first hole 21. As shown in the figure, a pair of shell connecting walls 20c is formed in the shape of an arc, more specifically in the shape of a circular arc, when viewed in section from the side of the first hole 21. It should be noted that that the expressions “arc shape” or “circular arc shape” in the present description include essentially “arc shape” or “circular arc shape”, as well as the case in which the connecting walls 20c form an angle that can be visually distinguished. The connecting walls 20c on their inner surfaces, that is, the surfaces facing the inside of the shell 20, have cuts or recesses 25. The cuts or recesses 25 extend between the first end surface 21a and the second end surface 22a of the shell 20. The cuts or recesses 25 can be formed by cutting grooves on the inner surfaces of the shell 20, cutting out portions of the inner surfaces, or compressing the inner surfaces. Additionally, the cuts or recesses 25 may be formed using laser processing. In other words, the notches or recesses 25 can also be called notch lines or recess lines formed on the inner surfaces of the connecting walls 20c. The connecting walls 20c are bent along the cuts or recesses 25, and as a result, said walls take the shape of an arc or a circular arc when viewed in section from the first hole 21.

[0052] According to the cartridge 10 shown in FIG. 9, since the shell 20 has a plurality of cuts or recesses 25, the material of the shell is easily bent along these cuts or recesses when the connecting walls 20c of the shell 20 are formed, even if it is made of a material having a certain degree of rigidity, such as cardboard. As a result, the connecting walls 20c of the shell 20 can be bent accordingly. In addition, the shape of the shell 20 having the connecting walls 20c is easily maintained compared with the shell in which the first shell wall 20a and the second shell wall 20b are connected by flat walls. Particularly, according to the shell 20 described in the present embodiment, the cuts or recesses 25 are deformed by contracting even if a force is applied to the shell 20 in a direction inclined relative to the first wall 20a, for example, the inner surfaces of the connecting walls 20c in which the the cuts or recesses 25 oppose each other by coming into mutual contact, and thus the shape of the shell 20 shown in FIG. 9, easy to store.

[0053] In addition, since each of the pair of connecting walls 20c of the shell 20 is formed in the form of an arc when viewed in section from the first hole 21, the stress exerted on the connecting walls 20c is dissipated, and the strength of the shell 20 can be increased compared to the shell , in which the first wall 20a and the second wall 20b are connected by flat walls. In addition, the cartridge 10 has air flow passages formed inside the shell 20 as described above. In particular, the air flow channels are provided by the first gaps 33 of the raw material part 30. Therefore, due to the ease of maintaining the shape of the shell 20, it is possible to limit the overlap of the air flow channels within the said shell.

[0054] The distance between the cuts or recesses 25 is preferably equal to or greater than 0.5 mm and 3 mm or less, and more preferably 0.5 mm or more and 1.5 mm or less. Here, the distance between cuts or recesses 25 means the distance between adjacent cuts or recesses 25 in the section shown in FIG. 9. If the distance between the cuts or recesses 25 is less than 0.5 mm, too short an interval may cause manufacturing difficulties. In addition, if the distance between the cuts or recesses 25 exceeds 3 mm, it becomes necessary to increase the size of the shell 20 itself to form the connecting walls 20c, and there is a possibility that its size does not fit the size of the cartridge 10 of the aroma inhaler 100. Moreover, if the distance between the notches or recesses 25 is 1.5 mm or less, the shapes of the connecting walls 20c can approximate the shape of a circular arc and will better distribute the load exerted on the shell 20. Thus, if the distance between the notches or recesses 25 falls within the above range, it is possible to securely form said cuts or recesses and form connecting walls 20c the size of which corresponds to the size of the cartridge 10.

[0055] The depth of the cuts or recesses 25 is preferably 30% or more and 90% or less, and more preferably 50% or more and 80% or less of the thickness of the connecting walls 20c. If the depth of the cuts or recesses 25 is less than 30% of the thickness of the connecting walls 20c, the material forming the shell 20 is difficult to bend and fold, and it may be difficult to form the connecting walls 20c properly. In addition, if the depth of the cuts or recesses 25 exceeds 90% of the thickness of the connecting walls 20c, there is a concern that the strength of the shell 20 itself will be too degraded. Therefore, if the depth of the cuts or recesses 25 falls within the above range, the formation of the connecting walls 20c can be ensured accordingly thus, and also preserves the strength of the shell 20 itself.

[0056] Although the connecting walls 20c are formed in the shape of an arc, which is provided by cuts or recesses 25 made in the shell 20 shown in FIG. 9, the present invention is not limited thereto, and the connecting walls 20c may have any fold lines (angle portions). For example, the shell 20 may have a substantially hexagonal cross-section formed by connecting walls 20c having a notch or recess 25 located at the boundary of each of the first wall 20a and the second wall 20b, and another notch or recess 25. By increasing the number of notches or recesses 25, it is possible ensure that the cross-sectional shapes of the connecting walls 20c approach the shape of an arc.

[0057] The angle formed by the surface of the inner wall adjacent to the notches or recesses 25, which are considered extreme when the notches or recesses 25 are formed in the inner surfaces of the connecting walls 20c, is preferably greater than 90° and less than 180°, and more preferably is 100° or more and 150° or less. If the cross-section of the shell 20 has, for example, a quadrangular shape, a portion is formed in which the angle made by the wall surfaces adjacent to the cuts or recesses 25, which are considered to be extreme, is 90° or less. The shape of the shell 20 made of cardboard having sufficient rigidity is difficult to maintain even when cuts or indentations 25 are formed due to the large reaction force of the cardboard resulting from bending the shell 20 at an angle that is 90° or less. If the shell 20 is made of cardboard whose rigidity is so low that the shape of the shell can be maintained, the strength of the shell is degraded. If the above angle is equal to or greater than 100° and 150° or less, the cross sections of the connecting walls 20c can be formed into a substantially arcuate shape.

[0058] The notches or recesses 25 are preferably located over an extent of at least 50% of the length between the first end surface 21a and the second end surface 22a of the shell 20. If the notches or indentations 25 are located over an extent of less than 50% of the length between the first end surface 21a and the second end surface 22a of the shell 20, the effect of facilitating the formation of the connecting walls 20c when folding the material forming the shell 20 is reduced. Therefore, if the length of the arrangement of all the cuts or recesses 25 is equal to or greater than the above numerical value, the connecting walls 20c can be easily bent along the said cuts or recesses.

[0059] In addition, as shown in the drawing, the cartridge 10 may include an adhesive 44 applied to the cuts or recesses 25. Thus, the adhesive 44 can maintain the curved shapes of the connecting walls 20c and, therefore, more firmly hold the shape of the shell 20 Additionally, the adhesive 44 may be configured to create an adhesion between the shell 20 and the raw material portion 30, as shown in FIG. 9. Here, the adhesive 44 can maintain the curved shapes of the connecting walls 20c and limit the deviation of the raw material part 30 relative to the shell 20. As the adhesive 44, for example, a vinyl acetate resin adhesive or a carboxymethylcellulose (CMC) adhesive can be used.

[0060] In addition, as shown in the drawing, the shell 20 and the raw material part 30 can be joined using an adhesive 40. Specifically, the inner surface of the shell 20 and at least a portion of the raw material part 30 are bonded with the adhesive 40. Thus, the deviation of the position of the raw material is limited portion 30 relative to the shell 20 when the heating plate 150a or current collector is inserted into the second gap 34 of the portion 30. As the adhesive 40, for example, a vinyl acetate resin adhesive or a carboxymethylcellulose (CMC) adhesive can be used.

[0061] As shown in FIG. 9, at least the first gaps 33 of the raw material portion 30 are exposed into the first opening 21. In the example illustrated in FIG. 9, the first opening 21 opens the first gaps 33 and the second gap 34 of the raw material portion 30. Aerosols generated from the raw material portion 30 can enter the user's mouth from the first opening 21 through the first gaps 33 since the said gaps open into the opening. Additionally, although not illustrated in FIG. 9, at least a second gap 34 of the raw material portion 30 is exposed into the second opening 22. Similar to the example shown in FIG. 9, the first gaps 33 and the second gap 34 of the raw material portion 30 extend into the second hole 22. In the present embodiment, the heating plate 150a or the current collector can be inserted into the second hole 22 since the second gap 34 opens into the hole.

[0062] FIG. 10 is a schematic side sectional view illustrating a cartridge 10 according to another embodiment. In fig. 10 shows a state in which the heating plate 150a of the aroma inhaler 100 is inserted into the cartridge 10. In the example shown in FIG. 10, the aroma inhaler 100 includes one heating plate 150a, and a vent hole 110a is provided in a side surface of the first body 110. As shown in the drawing, the second end surface 22a of the shell 20 is inclined relative to the first wall 20a. In this way, it is possible to allow air to flow into the cartridge 10 from the vent hole 110a formed in the side surface of the first housing 110.

[0063] FIG. 11 is a schematic side sectional view illustrating a cartridge 10 according to another embodiment. As shown in FIG. 11, the second end surface 22a of the shell 20 is inclined relative to the first wall 20a. Specifically, in the illustrated example, the second end surface 22a of the shell 20 is wedge-shaped. In this way, it is possible to allow air to flow into the cartridge 10 from the vent hole 110a formed in the side surface of the housing 110.

[0064] It should be noted that in the example depicted in FIG. 10, the first end surface 21a of the shell 20 is also inclined relative to the first wall 20a. Moreover, in the example shown in FIG. 11, the first end surface 21a of the shell 20 has a shape that corresponds to the second end surface 22a. This is because the second end surface 22a of the cartridge 10 (shell 20) and the first end surface 21a of the other cartridge 10 are formed simultaneously by cutting the raw material 10' (see FIG. 14) of the cartridge 10, as will be described later. As shown in FIG. 10 and 11, the first end surface 21a may intersect the first wall 20a in a perpendicular manner.

[0065] FIG. 12A is a perspective view illustrating the cartridge 10 according to another embodiment, FIG. 12B is a schematic sectional view along arrow 12B-12B in FIG. 12A. As shown in FIG. 12A and FIG. 12B, the shell 20 of the cartridge 10 includes guide portions 45 extending between a second end surface 22a defining the second opening 22 and a second gap 34 of the feed portion 30. In the illustrated example, the shell 20 includes a pair of guide portions 45, with each of the guide portions 45 extending between the second end surface 22a located on the side of the first wall 20a of the shell 20 and the second gap 34. Thus, the heating plate 150a or pantograph is guided by the guide parts 45 into the second gap 34 when the said plate or pantograph is inserted from the side of the second hole 22 , in this case it is possible to prevent their erroneous introduction into the first gaps 33.

[0066] Although the above example has been described on the assumption that the raw material portion 30 contains a base material layer 31 and a raw material layer 32, the present invention is not limited thereto, and the raw material portion 30 may not have a base material layer 31. In other words, the raw material portion 30 may consist of only the raw material layer 32. Here, the raw material portion 30 may be the aforementioned tobacco or non-tobacco web. The raw material portion 30 may be folded along fold lines that are similar to the fold lines made in the example in which the base material layer 31 is provided. However, since in this case the raw material part 30 does not have a base material layer 31, there is no formation of a second gap 34 in which the said layer faces itself. On the other hand, the first gaps 33 can be formed by folding the raw material portion 30 along the fold lines F1, F2 and F3 or fold lines F4, F5 and F6, without making full contact of the web using the reaction force caused by the elastic deformation resulting from the folding of the layer 32 raw materials.

[0067] Next, a method for manufacturing the cartridge 10 will be described. FIG. 13 is a schematic diagram of the manufacturing process of the raw material part 30 shown in FIG. 6. Fig. 14 is a schematic diagram of the manufacturing process of the cartridge 10 shown in FIG. 9. In FIG. 13 and 14 also show the length direction L1 and the width direction W1. As shown in FIG. 13, the web 30' constituting the raw material portion 30 moves to one side of the length direction L1 (to the left in the drawing) in a state in which the base material layer 31 is drawn into a suction conveyor, for example. During movement, the web 30' is first folded inward along fold line F1 and fold line F2, and thus the raw material layer 32 faces itself. The web 30' is then folded inwards along the fold line F2 and thus the base material layer 31 faces itself.

[0068] The folded web 30' is then placed on the shell web 20' as shown in FIG. 14. The casing web 20' is moved to one side (to the left in the drawing) of the length direction L1 in a state in which said web is drawn into, for example, a suction conveyor. The adhesive 40 is applied to the web 30' along the length direction L1 simultaneously with the movement of the shell web 20' and the web 30'. Then, one side (bottom side in the drawing) of the shell web 20' is folded in the width direction W1, and the connecting walls 20c shown in FIG. 4 and 9 are formed to surround the web 30', and an adhesive 42 is applied along the length direction L1 of the folded shell web 20'. In addition, the other side (upper side in the drawing) of the shell web 20' is folded in the width direction W1 , while the connecting walls 20c shown in FIG. 4 and fig. 9 are formed so as to surround the web 30', and the end portions of the shell web 20' are fastened in the width direction W1 by an adhesive 42, and the shell web 20' and the folded web 30' are fastened using an adhesive 40. In this way, a preform 10' is produced. cartridge 10. The cartridge 10 is made by cutting the workpiece 10' to a given length, for example, with a knife with a rounded blade. It should be noted that the cartridge 10 shown in FIG. 10 and 11 can be made by adjusting the cutting angle and the number of cuts made at this stage using a knife with a rounded blade or the like. As the adhesive 42, for example, a vinyl acetate resin adhesive or a carboxymethylcellulose (CMC) adhesive can be used.

[0069] FIG. 15 is a schematic perspective view of a cartridge according to another embodiment. The cartridge 12 shown in FIG. 15 contains any of the cartridges 10 shown in FIG. 4, 10, 11, 12A and 12B, a cooling portion 60, and a mouthpiece portion 70. The cooling portion 60 is for cooling aerosols generated from the feed portion 30 of the cartridge 10. Specifically, the cooling portion 60 may be a tube made of paper or a tube made of paper attached to metal, such as paper attached to aluminum. In case the cooling part 60 is made of paper attached to a metal, the cooling part 60 is preferably formed in a tubular form so that the aluminum surface is located inside the cooling part 60. Moreover, the cooling part 60 has a flattened tubular shape corresponding to the shape of the cartridge 10, as shown in the drawing. Thus, it is possible to improve the cooling efficiency compared to the case where the cooling portion 60 is a cylinder because the area in which steam or aerosols passing through the cooling portion 60 comes into contact with the inner surface of the portion is increased. The cooling portion 60 may be located or filled with one or more materials selected from the group consisting of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil. The cooling efficiency of aerosols with these materials can be increased by placing them in the cooling part 60 or filling it with these materials. It should be noted that the cooling part 60 may be configured with a vent hole to draw air from outside. By drawing air from outside into the cooling portion 60, the cooling efficiency can be improved. For example, the length of the cooling portion 60 may be 20 mm or more and 50 mm or less. It should be noted that the vent hole is preferably provided in the cooling portion 60 near the cartridge 10 because when the vent hole is located closer to the cartridge 10 (ie, the raw material portion 30), an enhanced cooling effect is achieved. In addition, the amount of outside air supplied from the vent to the cooling portion 60 is preferably 10% or more and 80% or less, and more preferably 20% or more and 50% or less of the main smoke flow.

[0070] The mouthpiece 70 is configured such that aerosols generated by the raw material portion 30 pass therethrough. In the illustrated example, the aerosols passing through the cooling portion 60 reach the user through the mouthpiece 70. The mouthpiece 70 may have a length such that the user could hold the said part in his mouth. The mouthpiece portion 70 may be a hollow tubular member or may be provided with a filter, such as an acetate or carbon filter, disposed within the member. Alternatively, the mouthpiece portion 70 may be a thin nonwoven material or the like. For example, the length of the mouthpiece portion 70 may be 5 mm or more and 25 mm or less. In addition, by increasing the length of the cooling part 60, a portion thereof can be used as a mouthpiece part 70.

[0071] The cooling portion 60 is located in the first end surface 21a of the cartridge 10 (shell 20). The mouthpiece portion 70 is located in the cartridge 10 on the reverse side of the cooling portion 60. The cartridge 12 may be formed by the cartridge 10, the cooling portion 60, and the mouthpiece portion 70 connected to each other, for example, by tipping paper, in an aligned state, as shown in the drawing.

[0072] FIG. 16 is a schematic sectional view illustrating an aroma inhaler 100 according to another embodiment. As shown in the drawing, the aroma inhaler 100 does not have a second body 120, a cooling part 160 and a mouthpiece 130 when compared with the aroma inhaler 100 shown in FIG. 2. The end portion of the first body 110 of the aroma inhaler 100 is open to the heating portion 150 and is configured such that the cartridge 12 shown in FIG. 15. The heating portion 150 may include a heating plate 150a or an induction coil 150b.

[0073] In the aroma inhaler 100 shown in FIG. 16, the cartridge 10 containing the cartridge 12 is inserted into the heating portion 150. Aerosols are generated by the feed portion 30 of the cartridge 10 heated by the heating portion 150, and the user can inhale the aerosols through the mouthpiece portion 70 of the cartridge 12. Since the illustrated example uses a cartridge 12 containing a cooling agent portion 60 and the mouthpiece portion 70, the aroma inhaler 100 may not have the second body 120, the cooling portion 160, and the mouthpiece 130. Thus, the adhesion of contaminants to the aroma inhaler 100 can be further reduced since contaminants do not adhere to the second body 120, the cooling portion 160 and mouthpiece 130.

[0074] FIG. 17 is a schematic perspective view showing a cartridge according to another embodiment. The cartridge 14 shown in FIG. 17 contains any of the cartridges 10 shown in FIG. 4, 10, 11, 12A and 12B, and a cooling portion 60. In other words, compared with the cartridge 12 shown in FIG. 15, cartridge 14 shown in FIG. 17, does not have a mouthpiece part 70.

[0075] FIG. 18 is a schematic sectional view illustrating an aroma inhaler 100 according to another embodiment. The aroma inhaler 100 shown in the drawing does not have a second body 120 and a cooling part 160 compared to the aroma inhaler 100 shown in FIG. 2. In other words, the aroma inhaler 100 shown in FIG. 18 is different from the aroma inhaler 100 shown in FIG. 16 in that it includes a mouthpiece 130. The end portion of the first body 110 of the aroma inhaler 100 is open on the side of the heating portion 150 and is configured such that the cartridge 12 shown in FIG. 17 may be inserted into the heating portion 150. The heating portion 150 may include a heating plate 150a or an induction coil 150b.

[0076] In the aroma inhaler 100 shown in FIG. 18, the cartridge 10 containing the cartridge 14 is inserted into the heating portion 150. Aerosols are generated by heating the feed portion 30 of the cartridge 10 by the heating portion 150, and the user can inhale the aerosols through the cooling portion 60 of the cartridge 14 and the mouthpiece 130 of the aroma inhaler 100.

[0077] FIG. 19 is a schematic perspective view illustrating a cartridge according to another embodiment. The cartridge 16 shown in FIG. 19 is different from the cartridge 14 shown in FIG. 17 in that the connecting walls 20c have a third hole 23. The cartridge 16 can be heated by inserting a heating plate 150a or a current collector from the third hole 23 of said cartridge. It should be noted that the cartridge 16 may not have a cooling portion 60 and may consist only of the cartridge 10. Moreover, the cartridge 10 may have a second opening 22, or the second end surface 22a may be closed.

[0078] In cartridges 12, 14 and 16 shown in FIGS. 15, 17 and 19, the shell 20 may serve as an outer layer of the cooling portion 60 and/or the mouthpiece portion 70, which is achieved by increasing the length of the shell 20 of the cartridge 10. In this case, the length of the shell 20 of the cartridge 10 shown in FIG. 15 (the length between the first end surface 21a and the second end surface 22a), for example, is preferably equal to or greater than 50 mm and 100 mm or less. In addition, the length of the shell 20 of the cartridge 10 shown in FIG. 17 and 19 (the length between the first end surface 21a and the second end surface 22a) is preferably equal to or greater than 25 mm and 95 mm or less. For example, as the cooling portion 60, a hollow portion of the shell 20, that is, a portion in which metal-attached paper such as aluminum-affixed paper is attached to the inner surface of the shell 20, a portion in which the above-mentioned cooling material is disposed, can be used. aerosols, or a portion filled with the above material, or the like. In addition, the hollow part of the shell 20 or the part in which the filter is located can be used as a mouthpiece part 70. As described above, since the shell 20 has cuts or recesses 25, the shape of the shell 20 is easily maintained even if the shell 20 is extended in length.

[0079] FIG. 20 is a schematic sectional view illustrating a cartridge 10 according to another embodiment. As shown in FIG. 20, the raw material portion 30 of the cartridge 10 is folded along three fold lines F1, F2 and F3, which are similar to the fold lines of the raw material portion 30 shown in FIG. 6. Here, the raw material portion 30 includes a first end portion 35 on which a fold line F1 or a fold line F2 is located, and a second end portion 36 located on a side opposite to the first end portion 35. In the illustrated example, a fold line F3 is located on the second end portion 36. The second gap 34 extends from the first end portion 35. Specifically, the second gap 34 extends from the first end portion 35 to the second end portion 36, as shown in FIG. 20. In the illustrated example, a heating plate 150a is inserted into the second gap 34.

[0080] The cartridge 10 shown in FIG. 20 is different from the cartridge 10 shown in FIG. 4, the directionality of the raw material part 30. In particular, in the cartridge 10 shown in FIG. 20, the raw material portion 30 is located inside the shell 20 such that the first end portion 35 faces the second opening 22 (second end surface 22a) of the shell 20. In other words, the raw material portion 30 is located inside the shell 20 such that the distance between the first end portion 35 of the raw material portion 30 and the second hole 22 (second end surface 22a) of the shell 20 is less than the distance between the second end portion 36 and the second hole 22 (second end surface 22a). Thus, the second gap 34 is open into the second hole 22. Therefore, when the heating plate 150a or the current collector of the heating part 150 is inserted through the second hole 22 as shown in the drawing, the heating part 150 easily fits into the second gap 34 where the base material layer 31 faces to yourself. Here, it is possible to effectively heat the raw material layer 32 without bringing the heating plate 150a or susceptor into contact with the layer by heating the raw material portion 30 with the heating plate 150a, susceptor or the like located in the second gap 34. Thus, preventing contamination of the heating plate 150a or susceptor by the raw material layer 32, and the frequency of cleaning operations of the heating plate 150a or susceptor can be reduced. In addition, steam or aerosols generated from the raw material layer 32 can pass through the second gap 33, where said layer 32 faces itself. Thus, steam or aerosols generated from the feed layer 32 can be effectively supplied to the downstream side. It should be noted that although in the example shown in FIG. 20, the shell 20 houses the raw material part 30 shown in FIG. 6, the raw material part 30 shown in FIG. can be inserted into the shell 20. 7 or fig. 8, in a direction similar to that shown in FIG. 20.

[0081] FIG. 21A is a schematic side view illustrating the cartridge 10 according to another embodiment. In fig. 21A shows the side surface of the cartridge 10 as viewed from the first opening 21. The cartridge 10 shown in FIG. 21A is different from the cartridge 10 shown in FIG. 4, in that several raw material parts 30 are located in the shell 20. In particular, the cartridge 10 shown in FIG. 21A, comprises two raw material portions 30. In the illustrated example, each of the raw material portions 30 may have a web in which a base material layer 31 and a raw material layer 32 are superimposed on each other, wherein the raw material portion may be formed in a tubular shape such that the layer 32 raw material is located inside. In addition, the raw material parts 30 are arranged facing each other in the thickness direction. As a result, the cartridge 10 has a second gap 34 formed by the base material layers 31 of the raw material parts 30 facing each other. In addition, each of the raw material parts 30 has a first gap 33 in which the raw material layer 32 faces itself. Each of the raw material parts 30 is preferably adhered to the inner surface of the shell 20 using an adhesive 40.

[0082] FIG. 21B is a schematic side view illustrating the cartridge 10 according to another embodiment. In fig. 21B is a side view of the cartridge 10 as viewed from the first opening 21. The cartridge 10 shown in FIG. 21B is different from the cartridge 10 shown in FIG. 21A in that it contains three raw material portions 30. In the illustrated example, each of the raw material portions 30 may comprise a web in which a base material layer 31 and a raw material layer 32 are superimposed on each other, wherein the raw material portion may be formed in a tubular shape such that that the raw material layer 32 is located inside. In addition, two of the three raw materials portions 30 are arranged to be adjacent to each other in the width direction, and the remaining one raw material portion 30 is located in the thickness direction and faces the two raw materials portions 30 that are adjacent to each other in the width direction. As a result, the cartridge 10 has a second gap 34 formed by facing each other of the base material layers 31 of two raw material parts 30 adjacent to each other in the width direction, and the base material layer 31 facing the remaining raw material part 30. Each raw material part 30 is preferably bonded to the inner surface of shell 20 using adhesive 40.

[0083] Since the cartridge 10 shown in FIG. 21A and 21B, multiple raw material parts 30 are included, and it is also possible to use raw material parts 30 with different raw material layers 32. Although the cartridge 10 shown in FIG. 21A and 21B, the raw material portions 30 are formed in a tubular shape, the present invention is not limited thereto, and the raw material portions may be webs that are simply folded so that the raw material layers 32 are not in a tubular shape but face each other. Moreover, in the cartridge 10 shown in FIG. 21A and 21B, the orientation of the raw material parts 30 can be changed relative to the cartridge 10 shown in FIG. 20. In other words, although the raw material parts 30 are arranged such that the axial direction of the tubular raw material parts 30 is oriented towards the second hole 22 (second end surface 22a) in the cartridge 10 shown in FIG. 21A and 21B, the raw material parts 30 may be arranged such that a radial direction of the tubular raw material parts 30 extends toward the second hole 22 (second end surface 22a).

[0084] Although the examples presented in FIGS. 20, 21A and 21B have been described on the assumption that the raw material parts 30 have base material layers 31 and raw material layers 32, the present invention is not limited thereto, and the raw material parts 30 may not contain base material layers 31. In other words, the raw material portions 30 may only consist of raw material layers 32 . Here, the raw material parts 30 may be the aforementioned tobacco or non-tobacco webs.

[0085] Although in the above-described embodiments, the heating plate 150a or pantograph is inserted into the second gap 34 and heats the cartridge 10, the present invention is not limited thereto, and the raw material portion 30 can be heated on one side of the surface by moving the heating plate 150a or pantograph to the side surface of the specified part. In this case, heat is gradually transferred from one side of the surface of the raw material part 30, and the smoking process can be extended in time.

[0086] Although embodiments of the present invention have been previously presented, the present invention is not limited to the above embodiments, and various modifications may be made without departing from the technical idea disclosed in the claims, specifications and drawings. It should be noted that any forms and materials not expressly described in the specification and not illustrated by the drawings are also within the scope of the technical idea of this practice of the invention, provided that the effects and advantages of these practical applications of the invention can be achieved.

[0087] Certain aspects discussed herein will now be described.

According to a first aspect, a cartridge for an aroma inhaler is provided. The cartridge contains: a raw material part, which heats up and thereby generates aerosols; and a shell in which the raw material is located. The shell has a first wall, a second wall facing the first wall, a pair of connecting walls that connect the first wall to the second wall, a first end surface formed with a first opening formed by the first wall, the second wall and a pair of connecting walls, and a second end surface, facing the section of the first end surface. On the inward facing surfaces of the shell, a pair of connecting walls have cuts or recesses extending between the first end surface and the second end surface, said connecting walls being bent along the cuts or recesses.

[0088] According to the first aspect, since the inner surfaces of the shell connecting walls have cuts or recesses, the shell material is easily folded along the cuts or recesses when forming the shell connecting walls, even if the shell is made of a material having a certain degree of rigidity, such as cardboard . As a result, the connecting walls of the shell can be bent accordingly. In addition, the first wall and the second wall are connected by a pair of connecting walls having cuts or recesses. Thus, the shape of the shell is easily maintained even if a force is applied to it in a direction inclined relative to the first wall, since the cuts or recesses are deformed by flattening, and the inner surfaces of the connecting walls in which the cuts or recesses are formed come into contact with each other.

[0089] According to the second aspect and in accordance with the first aspect, an air flow channel through which aerosols pass is formed in the shell.

[0090] According to the second aspect, the shape of the shell is easily maintained even if a force is applied to it in a direction inclined relative to the first wall, and thus blocking the air flow path inside the shell can be limited.

[0091] According to the third aspect and in accordance with the first or second aspect, the connecting walls have an arc shape when viewed in section and from the side of the first opening.

[0092] According to the third aspect, the connecting walls have arcuate cross-sections, so that stress applied to the connecting walls is dissipated, and the strength of the shell can be improved compared with the case where the first and second walls are connected by flat walls.

[0093] According to the fourth aspect and according to any of the first third aspects, the distance between the cuts or recesses is equal to or greater than 0.5 mm and is 3 mm or less.

[0094] The distance between cuts or recesses means the distance between adjacent cuts or recesses. If the distance between cuts or recesses is less than 0.5 mm, too short a spacing may cause manufacturing difficulties. In addition, if the distance between the cuts or recesses exceeds 3 mm, it becomes necessary to increase the size of the shell itself to form the connecting walls, and there is a possibility that its size does not fit the size of the aroma inhaler cartridge. According to a fourth aspect, it is possible to securely form the cuts or recesses and form connecting walls the size of which corresponds to the size of the aromatic inhaler cartridge.

[0095] According to the fifth aspect and according to any of the first fourth aspects, the depth of the cuts or recesses is 30% or more and 90% or less of the thickness of the connecting walls.

[0096] If the depth of the cuts or recesses is less than 30% of the thickness of the connecting walls, the material forming the shell is difficult to bend and fold, and it may be difficult to form the connecting walls accordingly. In addition, if the depth of the cuts or recesses exceeds 90% of the thickness of the connecting walls, there is a concern that the strength of the shell itself will be too degraded. According to the fifth aspect, it is possible to ensure that the connecting walls are formed appropriately and also to maintain the strength of the shell itself.

[0097] According to the sixth aspect and in accordance with any of the first fifth aspects, the angle formed by the surfaces of the inner wall adjacent to the cuts or recesses that are considered to be extreme is greater than 90° and less than 180°.

[0098] In the case where the cross-section of the shell has, for example, a quadrangular shape, there is a portion in which the angle formed by the wall surfaces adjacent to the cuts or recesses, which are considered to be extreme, is 90° or less. Even if cuts or depressions are formed in a casing made of cardboard having sufficient rigidity, the reaction force of the cardboard resulting from bending the casing at an angle that is 90° or less is significant, and therefore it is difficult to maintain the shape of the casing. If the shell is made of cardboard, the rigidity of which is so low that the shape of the shell can be maintained, the strength of the shell is degraded. According to the sixth aspect, the shape of the shell can be maintained even if it is made of cardboard having sufficient rigidity.

[0099] According to the seventh aspect and in accordance with any of the first sixth aspects, the cuts or recesses are located over an extent of at least 50% of the distance between the first end surface and the second end surface of the shell.

[0100] If the notches or recesses are located at an extent of less than 50% of the distance between the first end surface and the second end surface of the shell, the effect of facilitating the formation of connecting walls when folding the material forming the shell is reduced. According to the sixth aspect, the connecting walls can be easily bent along the cuts or recesses.

[0101] According to the eighth aspect, and according to any of the first to seventh aspects, an adhesive is provided that is applied to the cuts or recesses.

[0102] According to the eighth aspect, by using an adhesive, it is possible to maintain the curved shape of the connecting walls and thereby more stably maintain the shape of the shell.

[0103] According to the ninth aspect and in accordance with the eighth aspect, the adhesive is designed to provide adhesion between the shell and the raw material part.

[0104] According to the ninth aspect, by using an adhesive, it is possible to maintain the curved shape of the connecting walls and limit the deviation of the raw material part relative to the shell.

[0105] According to the tenth aspect and in accordance with any of the first ninth aspects, the raw material portion includes a web containing a raw material layer, and the cartridge has a first gap formed by the raw material layer facing itself.

[0106] According to the tenth aspect, the first gap defines an air flow path and therefore aerosols generated by the raw material layer can pass through the first gap. In this case, it is possible to ensure efficient delivery of aerosols generated by the raw material layer to the downstream side.

[0107] According to the eleventh aspect and in accordance with the tenth aspect, the raw material part web includes a layer of base material disposed on the raw material layer, and the cartridge has a second gap formed by the base material layer facing itself.

[0108] According to the eleventh aspect, the cartridge has a second gap and thus it is possible to efficiently heat the raw material layer by inserting the heating plate or current collector of the aroma inhaler into the second gap without bringing it into contact with the said layer. This prevents contamination of the heating plate or current collector with a layer of raw materials, and therefore the frequency of cleaning operations of the heating plate or current collector can be reduced.

[0109] According to the twelfth aspect and in accordance with the eleventh aspect, one portion of the second gap is larger than the other portion of said gap.

[0110] According to the twelfth aspect, in the second gap portion, a portion containing a large gap is formed, and thus the heating plate or pantograph easily fits into a relatively large portion of the second gap. Therefore, it is possible to prevent the heating plate or current collector from being inserted into the first gap by mistake.

[0111] According to the thirteenth aspect and in accordance with the twelfth aspect, the raw material portion includes a pair of inner folded portions that are folded along a first fold line and a second fold line and located within the raw material portion, and a pair of outer folded portions that are folded along a third fold line, located between the first and second fold lines, and located outside the raw material portion, wherein the size of the second gap between the first fold line and the second fold line is greater than the size of the second gap between the end portions of a pair of internal folded sections on the side opposite the first fold line or the second line fold.

[0112] According to the thirteenth aspect, a relatively large second gap is formed between the first fold line and the second fold line, and thus the heating plate or current collector easily fits into the relatively large portion of the second gap. Therefore, it is possible to prevent the heating plate or current collector from being inserted into the first gap by mistake.

[0113] According to the fourteenth aspect and according to any of the first to thirteenth aspects, the raw material layer comprises a non-tobacco web containing an aerosol source.

[0114] According to the fifteenth aspect, an aroma inhaler is provided. The aroma inhaler includes: a heating portion for heating a raw material portion of an aroma inhaler cartridge configured in accordance with any of the first to twelfth aspects; and a battery that supplies electricity to the heating part.
