JP 2022-118979 A

In a flavor inhalation stick that generates an aerosol by heating a base part including an aerosol source, a capsule may be disposed in an area where heat is applied. When the flavor inhalation stick is inserted into a flavor inhaler, it may be desired to destroy the capsule by heat and impart a new flavor by the contents released from the capsule. However, it is difficult to destroy a capsule by heat alone.
An object of the present disclosure is to provide a flavor inhalation stick and a flavor inhalation system that can impart a new flavor flavor by using a capsule placed in an area where heat is applied.

The present disclosure, which has been completed with respect to this objective, is a flavor inhalation stick that is heated when inserted into a flavor inhaler, and includes a heated portion that is subjected to heat when inserted into the flavor inhaler, and a capsule that is disposed within the heated portion and releases its contents when destroyed, wherein the capsule is not destroyed when either the heat or an external physical force is applied thereto, and is destroyed in part or in whole when both the heat and the external physical force are applied thereto.
Here, the breaking strength of the capsule, at which the capsule is broken to the extent that the content is released, may be reduced by application of the heat.
In addition, the capsule may not be destroyed if an external physical force is applied to it before the heat is applied, and may be partially or completely destroyed if the external physical force is applied to it after the heat is applied.
The capsule may also be configured so that the amount of the content released varies based on the number of times the external physical force is applied.
Furthermore, the breaking strength of the capsule, at which the capsule is broken to the extent that the content is released, may be reduced by application of the external physical force.
In addition, the capsule may not be destroyed if the heat is applied before the external physical force is applied, and may be partially or completely destroyed if the heat is applied after the external physical force is applied.
The capsule may be partially or completely destroyed when the heat and the external physical force are applied simultaneously.
Furthermore, the capsule may be partially or completely destroyed when the capsule is subjected to both heat of 100° C. or higher and a physical external force.
Furthermore, the present disclosure, which has been completed with the above object in mind, is a flavor inhalation system comprising the flavor inhalation stick and a flavor inhaler that heats the flavor inhalation stick.

According to the present disclosure, it is possible to provide a flavor inhalation stick that can impart a new flavor and taste by using a capsule placed in an area where heat is applied.

Below, an embodiment of the present disclosure will be described in detail with reference to the attached drawings. In each drawing, the same parts are denoted by the same reference numerals.

First Embodiment
FIG. 1 is a diagram showing a vertical cross section of a stick 1 according to a first embodiment.
The flavor inhalation stick (hereinafter, sometimes referred to as "stick") 1 according to the first embodiment includes a heated portion 10, a cooling portion 20, a filter portion 30, and a capsule 50. The heated portion 10 is formed in a cylindrical shape. Hereinafter, the direction of the center line CL of the heated portion 10 may be referred to as the "center line direction". The stick 1 further includes a tip paper 40 that integrates the heated portion 10, the cooling portion 20, and the filter portion 30 by winding them in a state in which they are arranged in the center line direction. Hereinafter, one end side in the center line direction (left side in FIG. 1) may be referred to as the first side, and the other end side in the center line direction (right side in FIG. 1) may be referred to as the second side. The first side is the end side that is inserted into the flavor inhaler 100. The second side is the end side opposite to the first side, which is the end side that the user holds in his mouth for inhalation. Moreover, a cross section along the center line direction is referred to as a "longitudinal cross section", and a cross section cut along a plane perpendicular to the center line direction is defined as a "transverse cross section".

[Flavor suction system]
Fig. 2 is an overall perspective view of the flavor inhaler 100 according to the first embodiment. Fig. 3 is a cross-sectional view of the flavor inhaler 100 according to the first embodiment. Note that in Fig. 3, the internal configuration of the flavor inhaler 100 that is not normally visible to the user is omitted.
The flavor inhalation system according to the present embodiment includes the stick 1 according to the first embodiment and a non-combustion heating type flavor inhaler 100 that externally heats the heated portion 10 of the stick 1. The stick 1 according to the first embodiment is inserted into the non-combustion heating type flavor inhaler 100 for use.
2, the flavor inhaler 100 includes a front cover 110 that buffers heat released from inside the device to the outside, a pushing member 115 that pushes the stick 1, a main body housing 120 to which the front cover 110 can be attached and detached, and a shutter 150 that opens and closes an insertion port into which the stick 1 is inserted. The main body housing 120 accommodates a main body 130 of the flavor inhaler 100. As shown in FIG. 3, the main body 130 includes a holding portion 140 that holds the stick 1, and an insertion port 142 that connects an internal space 141 to the outside and into which the stick 1 is inserted.

2 shows the shutter 150 blocking the insertion opening 142. The shutter 150 has a sliding mechanism and is movable along the surface of the outer shell between a first position that blocks the insertion opening 142 and a second position that opens the insertion opening 142. The insertion opening 142 is opened when the user places a finger on the shutter 150 and slides it along the side. As a result of the insertion opening 142 being opened, the user inserts the stick 1 into the holding portion 140 that holds the stick 1, as shown in FIG. 3.

3 is, for example, a screw-shaped member. As shown in FIG 3, the pressing member 115 is located adjacent to the internal space 141 and is movable into the internal space 141.
When the pushing member 115 moves into the internal space 141, it applies a physical external force to at least a part of the region of the stick 1 where the capsule 50 is disposed. Specifically, the pushing member 115, which is moved into the internal space 141 by the user turning it, indirectly applies pressure to the capsule 50.
The pushing member 115 is not limited to a screw-shaped member, and may be any member that is movable into the internal space 141. The pushing member 115 may be, for example, a member that moves into the internal space 141 when pressed by a user.
The means for applying a physical external force to the capsule 50 is not limited to the means described above, and any known technology may be used.

FIG. 4 is a schematic diagram showing an example of the internal configuration of the flavor inhaler 100.
As shown in Fig. 4, the main body 130 of the flavor inhaler 100 includes a power supply unit 131 that accumulates power and supplies power to each component of the main body 130, a sensor unit 132 that detects various information related to the main body 130, and a notification unit 133 that notifies the user of the information. The main body 130 also includes a storage unit 134 that stores various information for the operation of the main body 130, a communication unit 135 for transmitting and receiving information between the main body 130 and other devices, and a control unit 136 that controls the overall operation within the main body 130. The main body 130 also includes a heating unit 121 that heats the stick 1, and a heat insulating unit 144 that prevents heat transfer from the heating unit 121 to other components of the main body 130. In the flavor inhaler 100, the user inhales with the stick 1 held in the holding unit 140.

The heating unit 121 heats the heated portion 10 of the stick 1. The heating unit 121 is made of any material, such as metal or polyimide. For example, the heating unit 121 is configured in a film shape and arranged to cover the outer periphery of the holding unit 140. When the heating unit 121 generates heat, the aerosol source contained in the base material portion 11 (see FIG. 1) of the stick 1 is heated from the outer periphery of the stick 1. The heating unit 121 generates heat when power is supplied from the power supply unit 131. As an example, power may be supplied when the sensor unit 132 detects that a specific user input has been made. When the temperature of the stick 1 heated by the heating unit 121 reaches a specific temperature, the user can inhale. Thereafter, when the sensor unit 132 detects that a specific user input has been made, power supply may be stopped. As another example, power may be supplied and aerosol may be generated during the period in which the sensor unit 132 detects that the user has inhaled.

The insulating section 144 is arranged so as to cover at least the outer periphery of the heating section 121. For example, the insulating section 144 is made of a vacuum insulating material, an aerogel insulating material, or the like. Note that a vacuum insulating material is an insulating material in which, for example, glass wool and silica (silicon powder) are wrapped in a resin film and placed in a high vacuum state, thereby reducing the thermal conduction of gas to as close to zero as possible.

[Stick 1]
The stick 1 is a non-combustion heating type flavor inhalation article.
The cross section of the stick 1 is substantially circular, and its outer diameter and size in the direction of the center line can be appropriately changed according to the size of the product.

[Cooling section 20]
The cooling unit 20 is disposed adjacent to the heated unit 10 and the filter unit 30, and is a part formed so that the cross section of a cylinder or the like is hollow (hollow) by wrapping the sheet 21 around it. The cooling unit 20 cools the steam generated by heating the heated unit 10 to generate an aerosol. The cooling unit 20 is, for example, a paper tube formed by wrapping the sheet 21 made of paper around it.

The cross section of the cooling section 20 is substantially circular, and the outer diameter thereof may be appropriately changed according to the size of the product, but is preferably approximately the same as the outer diameter of the first filter 31 described below. If the cross section is not circular, the outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of the circle is applied.
The size of the cooling section 20 in the center line direction can be changed as appropriate to suit the size of the product, but it is desirable for the size to be such that a sufficient cooling effect can be ensured while obtaining a good flavor and that loss due to the generated steam and aerosol adhering to the sheet 21 can be suppressed.

The material of the sheet 21 is not particularly limited, and may be, for example, a material whose main component is pulp, or may be a material whose main component is any of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil, or any combination of these.
Although the cooling section 20 is formed by rolling the sheet 21, the cooling section 20 is not limited to this configuration as long as the cross section is hollow. The cooling section 20 may be formed, for example, by a pipe of synthetic resin or the like that already has a hollow cross section.

The cooling section 20 is provided with a plurality of through holes 60 (also referred to as "ventilation filters (Vf)" in this technical field) arranged circumferentially and concentrically. The through holes 60 are holes that penetrate the sheet 21. Examples of the hole shapes include polygonal, rounded polygonal, circular, and elliptical. The through holes 60 are present in an area through which air can flow in from outside the stick 1, in other words, in an area that protrudes from the insertion opening 142 when the stick 1 is held in the holding section 140 of the flavor inhaler 100.

The presence of the through-holes 60 allows the concentration of the inhaled flavor components and aerosol to be adjusted. In addition, the presence of a plurality of through-holes 60 allows air to flow from the outside into the cooling section 20 during inhalation, thereby lowering the temperature of the steam and air flowing in from the base section 11.
In addition, when the base material 11 is heated, the vapor generated using the aerosol as a condensation nucleus is liquefied by contacting air from the outside and decreasing in temperature, thereby promoting the generation of the aerosol.

When a plurality of through holes 60 that are concentrically arranged in the cooling section 20 are treated as one through hole group, the number of through hole groups may be one or may be two or more.
Furthermore, when the stick 1 is configured such that the heated portion 10, the cooling portion 20, and the filter portion 30 are wound with tipping paper 40, the tipping paper 40 is preferably provided with an air hole at a position directly above the through hole 60 provided in the cooling portion 20. When producing such a stick 1, tipping paper 40 provided with an air hole that overlaps with the through hole 60 may be prepared and wound, but from the viewpoint of ease of production, it is preferable to produce a stick 1 without a through hole 60 and then open a hole that penetrates the cooling portion 20 and the tipping paper 40 at the same time.

[Filter section 30]
The filter section 30 has a first filter 31 connected to the second side of the cooling section 20, and a second filter 32 located on the second side of the first filter 31. The first filter 31 has a hollow cross section, and the second filter 32 has a solid cross section.
The filter unit 30 is connected (coupled) to the second end of the cooling unit 20 by integrally winding up the first end of the filter unit 30 using tipping paper 40 described later. The first filter 31 and the second filter 32 may also have a winding paper 33 wound between the outer circumferential surfaces of the first filter 31 and the second filter 32 and the tipping paper 40.

The cross sections of the first filter 31 and the second filter 32 of the filter section 30 are substantially circular, and the diameter of the circle and the circumference of the cross section can be changed as appropriate to suit the size of the product. If the cross section is not circular, the above diameter is assumed to be a circle having the same area as the cross section, and the diameter of that circle is applied.

The first filter 31 and the second filter 32 are not particularly limited as long as they contain a filter material and have a general function of a filter. The general function of a filter includes, for example, reduction of undesirable sensations such as irritation, reduction of nicotine and tar, and adjustment of the amount of air mixed in when inhaling an aerosol or the like when an opening corresponding to the through hole 60 is present on the second side of the filter, but it is not necessary for them to have all of these functions. In addition, in the stick 1, which tends to generate fewer components and has a lower filling rate of the aerosol source in the base material 11 compared to cigarette products, preventing the aerosol source from falling off while suppressing the filtering function and adjusting the air resistance to provide appropriate ease of inhalation when inhaling are also important functions.
The filter material constituting the first filter 31 and the second filter 32 is, for example, a filler such as cellulose acetate fiber, nonwoven fabric, pulp paper, etc., formed into a cylindrical shape. Alternatively, a paper filter filled with sheet-shaped pulp paper may be used.

The form of the wrapping paper 33 is not particularly limited, and may include one or more rows of seams containing adhesive. The adhesive may include a hot melt adhesive, and the hot melt adhesive may further include polyvinyl alcohol. In addition, when the filter part 30 is composed of two or more members, it is preferable that the wrapping paper is wound around each of these two or more members, and then wrapped with another wrapping paper.
The material of the wrapper 33 is not particularly limited, and any known material can be used, which may contain a filler such as calcium carbonate.
Furthermore, the wrapper 33 may be either coated or uncoated, but is preferably coated with a desired material from the standpoint of imparting functions such as strength and structural rigidity.

[Tip Paper 40]
The tipping paper 40 is wound around the outer peripheral surfaces of the heated portion 10, the cooling portion 20, and the filter portion 30. The shape of the tipping paper 40 is not particularly limited, and is, for example, a square or rectangular shape.
The configuration of the tipping paper 40 is not particularly limited and may be a general embodiment, for example, one in which pulp is the main component. The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing non-wood pulp that is generally used in cigarette papers for tobacco products, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in combination in any ratio.
In addition to the above-mentioned materials, the tipping paper 40 may contain fillers, for example, calcium carbonate from the viewpoint of improving whiteness and opacity and increasing the heating rate. In addition to the above-mentioned materials and fillers, the tipping paper 40 may contain various auxiliary agents, and may contain water resistance improvers including wet strength agents (WS agents) and sizing agents.

A coating agent may be added to at least one of the two surfaces, the front surface and the back surface, of the tipping paper 40. There are no particular limitations on the coating agent, but a coating agent that can form a film on the surface and reduce liquid permeability is preferred.
A portion of the outer surface of the tipping paper 40 may be coated with a known lip release material, by which is meant a material configured to assist in easy release of contact between the lips and the tipping paper 40 when the user holds the filter portion 30 of the stick 1 in their mouth, without substantial sticking.

[Heated part 10]
The heated part 10 has a substrate part 11 including an aerosol source, a wrapping paper 12 covering the outer periphery of the substrate part 11, a solid member 13 preventing the substrate part 11 from falling off from the end face on the first side of the heated part 10, and a capsule 50 that releases a content 51 when a coating 52 is destroyed. The heated part 10 is connected (coupled) to the cooling part 20 by winding up the cooling part 20 and the heated part 10 together using tipping paper 40.
The heated portion 10 is formed into a cylindrical shape by winding the substrate portion 11 and the solid member 13 with the wrapping paper 12. When the heated portion 10 is made of two or more members such as the substrate portion 11 and the solid member 13, it is preferable that the wrapping paper 12 is wound with each of these two or more members, and then the two or more members are further wrapped with another wrapping paper 12.

The aerosol source filled in the base material 11 may be tobacco-derived, such as tobacco shreds or a processed product formed into granules, sheets, or powder from tobacco raw materials. The aerosol source may also include non-tobacco-derived aerosol sources made from plants other than tobacco (e.g., mint and herbs). As an example, the aerosol source may include a flavoring. The type of flavoring is not particularly limited, and menthol is particularly preferred from the viewpoint of imparting a good flavor. When the flavor inhaler 100 is a medical inhaler, the aerosol source may include a drug for the patient to inhale. Note that the aerosol source is not limited to a solid, and may be, for example, a polyhydric alcohol such as glycerin and propylene glycol, and a liquid such as water. At least a portion of the base material 11 is accommodated in the internal space 141 of the holding part 140 when the stick 1 is held by the holding part 140.

The size of the base material 11 in the center line direction and the content of the aerosol source can be appropriately changed according to the size of the product.
The aerosol source may also include tobacco shreds. The material of the tobacco shreds is not particularly limited, and known materials such as lamina and ribs can be used. Alternatively, the tobacco shreds may be made by crushing dried tobacco leaves to obtain tobacco shreds, homogenizing the shreds using known means, and processing the shreds into a sheet (hereinafter, simply referred to as homogenized sheet). Furthermore, the aerosol source may be a so-called strand type, in which homogenized sheets having a size similar to the size of the center line direction of the substrate 11 are filled with shreds approximately horizontal to the center line direction of the substrate 11.
Examples of tobacco types include flue-cured, burley, orient, native, other Nicotiana tabacum varieties, Nicotiana rustica varieties, and mixtures thereof. The mixtures are appropriately blended to achieve the desired flavor.

The shape of the wrapping paper 12 is, for example, a square or a rectangle. When the aerosol source is wrapped in the wrapping paper 12 into a cylindrical shape, for example, an end of the wrapping paper 12 and an end of the wrapping paper 12 on the opposite side are overlapped by about 2 mm in the circumferential direction and glued together to form a cylindrical paper tube shape in which the aerosol source is filled.
The material of the cigarette paper 12 is not particularly limited, and examples thereof include those mainly composed of pulp. Pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing with non-wood pulp that is generally used for cigarette paper 12 for tobacco products, such as flax pulp, hemp pulp, sisal pulp, or esparto.
As the type of pulp, chemical pulp produced by the kraft cooking method, acidic/neutral/alkaline sulfite cooking method, soda salt cooking method, etc., ground pulp, chemi-ground pulp, thermomechanical pulp, etc. can be used.

The solid member 13 is a member that prevents the base member 11 from falling off from the end face on the first side of the heated portion 10, and has a capsule 50 embedded therein. For example, the capsule 50 is embedded in the center of the cross section of the solid member 13.
The cross section of the solid member 13 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the product. If the cross section is not circular, the above diameter is assumed to be a circle having the same area as the cross section, and the diameter of the circle is applied.

The material constituting the solid member 13 is not particularly limited, but is preferably a material through which the contents 51 of the capsule 50 can permeate. For example, the material constituting the solid member 13 may be a paper filter filled with sheet-like pulp paper, or a filter formed into a cylindrical shape from a filling such as cellulose acetate fiber, nonwoven fabric, or pulp paper.

The capsule 50 includes a content 51 including a flavor component and a coating 52 that holds the content 51. The content 51 may include, for example, an aerosol source, or may include only the aerosol source without including a flavor component.
The capsule 50 is a filling placed inside the heated portion 10. The capsule 50 is preferably embedded in the vertical cross section of the heated portion 10 at a position where the contents 51 do not leak out from the first end face and the second end face of the solid member 13. In other words, the capsule 50 is preferably placed at a position where the diffusion of the contents 51 is contained within the solid member 13.

The contents 51 include, for example, a flavor component as a flavor component. The contents 51 may also include, for example, a taste component as a flavor component.
The flavoring ingredient is not particularly limited, and examples thereof include powder flavorings and oil-based flavorings. Major powder flavorings include powdered chamomile, fenugreek, menthol, peppermint, cinnamon, herbs, etc. Major oil-based flavorings include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, peppermint, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, coffee, tobacco, etc. The flavoring ingredient may be used alone or in combination of two or more kinds. When using a powder flavoring, its particle size is preferably 500 μm or less.
Examples of flavor components include citric acid, tartaric acid, sodium glutamate, neotame, thaumatin, stevia, sorbitol, xylitol, erythritol, aspartame, rutin, hesperidin, oxalic acid, tannic acid, catechin, naringin, quinine, quinic acid, limonin, caffeine, capsaicin, vitamins, amino acids, polyphenols, alginic acid, flavonoids, lecithin, etc. The flavor component is preferably substantially soluble in liquid or in the oral cavity.

In addition to the flavor components, the contents 51 may contain coloring agents such as synthetic coloring agents, natural coloring agents, etc. The coloring agents are preferably food additives such as Red No. 3, 106, beta-carotene, copper chlorophyllin, gardenia blue pigment, and Yellow No. 4.
The contents 51 may further contain a solvent for dissolving the flavor components and coloring agents. Examples of the solvent include medium-chain fatty acid triglyceride, glycerin, propylene glycol, water, and ethanol.

When the contents 51 are liquid or gel-like, the boiling point of the contents 51 is preferably higher than the temperature at which the coating 52 melts.
Furthermore, when the contents 51 are liquid or gel-like, the viscosity of the contents 51 is preferably such that the contents 51 permeate the solid member 13 and do not leak out from the first end face and the second end face of the solid member 13. Furthermore, the liquid amount of the contents per cross-sectional area of the solid member 13 is preferably such that the contents 51 permeate sufficiently into the solid member 13 and do not reach the first end face of the stick 1 and spill into the flavor inhaler 100. This makes it possible to impart a new smoking flavor when the contents 51 spreads within the solid member 13 while preventing the contents 51 from seeping out to the outside of the stick 1.

The coating 52 enclosing the contents 51 is not destroyed when either the heat from the heating unit 121 or the physical external force from the pushing member 115 is applied, but is partially or completely destroyed when both the heat from the heating unit 121 and the physical external force from the pushing member 115 are applied. Here, "partially destroyed" means that the coating 52 is cracked to the extent that the contents 51 are gradually released, or that a hole is opened in the coating 52. Also, "completely destroyed" means that the coating 52 is cracked to the extent that the contents 51 are released all at once, or that the coating 52 is melted.

The temperature at which the coating 52 melts is not particularly limited, but is preferably 100°C or higher from the viewpoint of maintaining the shape of the capsule 50 when only heat from the heating unit 121 is applied. Also, the temperature at which the coating 52 melts is preferably 300°C or lower from the viewpoint of destroying the capsule 50 when both heat from the heating unit 121 and a physical external force from the pushing member 115 are applied.

The strength of the coating 52 is such that it is destroyed when both heat from the heating unit 121 and a physical external force from the pushing member 115 are applied to it. The strength of the coating 52 is also such that it will not be destroyed when only a physical external force from the pushing member 115 is applied to it. The strength of the coating 52 is such that it will not be destroyed when the area where the capsule 50 is located is pressurized, for example, by pressing the stick 1 held between the user's thumb and index finger with the thumb and index finger. In other words, the strength of the coating 52 is such that it will not be destroyed when heat from a person's body temperature and a physical external force from a person are applied to it.

The composition of coating 52 is not particularly limited, so long as it is a composition that is not destroyed when either heat or a physical external force is applied, and is destroyed when both heat and a physical external force are applied.
Examples of materials for the coating 52 include starch, dextrin, polysaccharides, agar, gellan gum, gelatin, polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene-acrylonitrile copolymers, styrene-butadiene-acrylonitrile copolymers, polyethylene, polypropylene, cellulose acetate, polyethylene terephthalate, polyamide, ethylene-acrylic acid plastics, ethylene-vinyl acetate plastics, ethylene-vinyl alcohol plastics, lipophilic materials, various natural gelling agents, etc. Furthermore, the coating 52 may contain fragrance components, plasticizers, colorants, etc.
Examples of lipophilic materials include fats and oils, fatty acids, sugar fatty acid esters, hydrocarbons, aromatic hydrocarbons, linear ethers, higher fatty acid esters, higher alcohols, and hydrogenated products thereof. Examples of fats and oils include glycerin fatty acid esters of safflower oil, linseed oil, sesame oil, olive oil, soybean oil, mustard oil, rapeseed oil, corn oil, castor oil, evening primrose oil, palm kernel oil, jojoba oil, cottonseed oil, coconut oil, peanut oil, cacao oil, and the like. Examples of sugar fatty acid esters include sucrose fatty acid esters. Examples of hydrocarbons include terpenes, paraffin, beeswax, and the like. Examples of hydrogenated products include hydrogenated fats and oils such as margarine and shortening.
The composition of coating 52 may be based on any of the above materials, or any combination thereof.

When the capsule 50 is subjected to both heat of 100° C. or higher and a physical external force, the coating 52 of the capsule 50 is destroyed partially or entirely.
In this embodiment, the breaking strength of the capsule 50 at which the capsule 50 is broken to the extent that the content 51 is released changes when heat is applied from the heating unit 121. Specifically, the breaking strength of the coating 52 of the capsule 50 at which the capsule 50 is broken to the extent that the content 51 is released decreases when heat is applied from the heating unit 121.
In other words, in the present embodiment, the strength of the coating 52 changes when heat is applied from the heating unit 121. Specifically, when heat from the heating unit 121 is applied to the coating 52, the coating 52 becomes brittle.

Here, the breaking strength is the degree to which the capsule 50 is not broken to the extent that the contents are released.
For example, the breaking strength may be the maximum value of the stress immediately before the capsule 50 is broken. The maximum value of the stress immediately before the capsule 50 is broken can be measured using a rheometer such as CR-3000EX-S manufactured by Sun Scientific Co., Ltd., which uses contacts designed for compressive strength tests. As the contacts continue to descend, the capsule 50 begins to distort, generating stress on the contacts.
Also, for example, the breaking strength may be the temperature applied to the capsule 50 just before the capsule 50 is broken, or a value related to the hydrophilicity or hydrophobicity of the coating of the capsule 50. Alternatively, for example, the breaking strength may be determined based on at least two of the above contents.

For example, if a physical external force is applied by the pushing member 115 before the heat from the heating unit 121 is applied to the capsule 50, the coating 52 will not be destroyed, but if a physical external force is applied by the pushing member 115 after the heat from the heating unit 121 is applied to the capsule 50, the coating 52 will be destroyed.
In addition, for example, if a physical external force is applied by the pushing member 115 before the heat from the heating unit 121 is applied to the capsule 50, the coating 52 will not be destroyed, but if the heat from the heating unit 121 and the physical external force from the pushing member 115 are applied to the capsule 50 simultaneously, the coating 52 will be destroyed.

The amount of contents 51 released when coating 52 is ruptured varies based on the external physical force applied to capsule 50 .
When a physical external force sufficient to destroy a part of the coating 52 is applied multiple times to the capsule 50 after it has been heated by the heating unit 121 or while it is being heated, the amount of the contents 51 held in the coating 52 is reduced and a larger amount of the contents 51 is released, compared to when the physical external force is applied only once. Also, when a gradually increasing physical external force is applied to the capsule 50 after it has been heated by the heating unit 121 or while it is being heated, the contents 51 are released as if they are seeping out from the coating 52, and the concentration of the flavor and aroma can be adjusted by the capsule 50.
In addition, if a physical external force sufficient to destroy the entire coating 52 is applied all at once to the capsule 50 after it has been heated by the heating unit 121 or while it is being heated, the contents 51 are forcefully released from the capsule 50, making it possible to increase the concentration of the flavor and aroma imparted by the capsule 50.

In the present embodiment, the breaking strength of the capsule 50 at which the capsule 50 is broken to the extent that the content 51 is released may be changed by application of a physical external force by the pushing member 115. Specifically, the breaking strength of the capsule 50 at which the capsule 50 is broken to the extent that the content 51 is released may be decreased by application of a physical external force by the pushing member 115.
For example, if heat is applied by the heating unit 121 before a physical external force is applied to the capsule 50 by the pushing member 115, the coating 52 will not dissolve to the extent that part or all of the capsule will be destroyed, but if heat is applied by the heating unit 121 after a physical external force is applied to the capsule 50 by the pushing member 115, the coating 52 will dissolve and be destroyed.
In addition, for example, if heat is applied by the heating unit 121 before the physical external force by the pushing member 115 is applied to the capsule 50, the coating 52 will not melt, but if the heat by the heating unit 121 and the physical external force by the pushing member 115 are applied to the capsule 50 simultaneously, the coating 52 will melt and be destroyed.
Additionally, the amount of contents 51 released when coating 52 is ruptured may vary based on the temperature of heat applied to capsule 50 .

Additionally, in this embodiment, the state of the content 51 of the capsule 50 may change. Specifically, the content 51 may be solid at room temperature, but may be changed into liquid by heat from the heating unit 121.
For example, when the pushing member 115 applies a physical external force to the capsule 50 while the contents 51 are in a solid state, the coating 52 will not be destroyed, but when the pushing member 115 applies a physical external force to the capsule 50 while the contents 51 are in a liquid state due to the heat from the heating unit 121, the coating 52 may be destroyed. In other words, the breaking strength of the capsule 50 at which the capsule 50 is broken to the extent that the contents 51 are released may be reduced by the contents 51 of the capsule 50 being liquefied by the heat from the heating unit 121.

The shape of the capsule 50 is not particularly limited, and may be a sphere, a cylinder, a truncated cone, etc. Furthermore, a plurality of capsules 50 may be arranged.
The capsule 50 is preferably an elastic body that elastically deforms when an external physical force is applied, but returns to its original shape when the external physical force is no longer applied, and generates no stress. Alternatively, the capsule 50 may be an object that maintains the deformed shape when an external physical force is applied, and generates stress even when the external physical force is no longer applied.
The method for producing the capsule 50 is not particularly limited, but it is preferable to use, for example, a dropping method that can produce a capsule 50 having a seamless coating 52.

As explained above, the stick 1 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a heated portion 10 that is heated when inserted into the flavor inhaler 100, and a capsule 50 that is disposed within the heated portion 10 and releases contents 51 when destroyed. The capsule 50 is not destroyed when either heat from the heating portion 121 or a physical external force from the pushing member 115 is applied to it, but is partially or completely destroyed when both heat from the heating portion 121 and a physical external force from the pushing member 115 are applied to it. Note that the stick 1 does not need to have the cooling portion 20 shown in FIG. 1 from the viewpoint of compact size in the center line direction.

The stick 1 is inserted into the holding section 140 of the flavor inhaler 100. After the temperature of the base material section 11 heated by the heating section 121 reaches a predetermined temperature, the user inhales and an aerosol is generated. When the user inhales, the vapor and aerosol are cooled by the cooling section 20.

The heated portion 10 has a substrate portion 11 filled with an aerosol source, and a solid member 13 in which a capsule 50 is disposed.
Here, it is assumed that the heating unit 121 of the flavor inhaler 100 is in contact with the region where the base material 11 is arranged but is not in contact with the region where the solid member 13 is arranged. Heat is applied to the capsule 50 by the heating unit 121. Specifically, the heat in the base material 11 heated by the heating unit 121 is transmitted to the solid member 13, and the heat from the heating unit 121 is applied to the capsule 50.
Further, a physical external force is applied to the capsule 50 by the pushing member 115. Specifically, a region of the stick 1 in which the solid member 13 is arranged is pushed by the pushing member 115, and the physical external force is applied to the capsule 50 by the pushing member 115.
When both heat from the heating unit 121 and a physical external force from the pushing member 115 are applied to the capsule 50, the coating 52 is partially or entirely destroyed, releasing the contents 51. This allows the stick 1 to be imparted with a new flavor or aroma by the capsule 50 placed in the heated area.

The breaking strength of the capsule 50 , at which the capsule 50 is broken to the extent that the content 51 is released, is preferably reduced by applying heat from the heating unit 121 .
The capsule 50, whose breaking strength is reduced by the heat from the heating unit 121, can impart a new flavor and aroma.

For example, the capsule 50 will not be destroyed if a physical external force is applied by the pushing member 115 before heat is applied by the heating unit 121, and may be partially or completely destroyed if a physical external force is applied by the pushing member 115 after heat is applied by the heating unit 121.
In comparison with a configuration in which the capsule 50 is broken only by the physical external force of the pushing member 115, unintended breakage of the capsule 50 can be suppressed. In addition, compared with a configuration in which the capsule 50 is broken only by the physical external force of the pushing member 115, a larger amount of flavor components contained in the contents 51 can be inhaled by the user together with the aerosol generated by heating the base material portion 11, in a configuration in which the capsule 50 is broken only by the physical external force of the pushing member 115, it is difficult to change the flavor of the aerosol while the user is inhaling. The capsule 50 is broken when a physical external force is applied by the pushing member 115 after heat is applied by the heating unit 121, so that the capsule 50 can impart a new flavor at the timing desired by the user.

Furthermore, it is preferable that the amount of the content 51 released from the capsule 50 varies based on the number of times that a physical external force is applied by the pushing member 115 .
The capsule 50 can be given a flavor and taste of a desired concentration based on the number of times that the pressing member 115 exerts a physical external force on the capsule 50 .

In addition, it is preferable that the breaking strength of the capsule 50 , at which the capsule 50 is broken to the extent that the content 51 is released, is reduced by applying a physical external force from the pushing member 115 .
After application of the external physical force, the capsule 50 can be destroyed by heat.

For example, the capsule 50 will not be destroyed if heat is applied by the heating unit 121 before the external physical force is applied by the pushing member 115, and may be partially or completely destroyed if heat is applied by the heating unit 121 after the external physical force is applied by the pushing member 115.
Specifically, the capsule 50 will not be destroyed when only heat is applied from the heating unit 121, but it is preferable that a physical external force is applied from the pushing member 115 so that the capsule 50 is partially or completely destroyed by the heat from the heating unit 121.
After application of the external physical force, the capsule 50 can be destroyed by heat.

In addition, it is preferable that the capsule 50 is partially or completely destroyed when the heat from the heating unit 121 and the physical external force from the pressing member 115 are simultaneously applied thereto.
Heat can be used to destroy the capsule 50 .

It is preferable that the capsule 50 is partially or completely destroyed when it is subjected to both heat from the heating unit 121 that heats the capsule 50 to 100° C. or higher, and a physical external force from the pushing member 115 .
In comparison with a configuration in which the coating 52 is destroyed when the capsule 50 is subjected to heat of less than 100° C. by the heating unit 121, unintentional destruction of the capsule 50 can be suppressed.

Second Embodiment
FIG. 5 is a diagram showing a vertical cross section of the stick 2 according to the second embodiment.
The stick 2 according to the second embodiment is different from the stick 1 according to the first embodiment in that the heated portion 210 corresponds to the heated portion 10. The differences from the first embodiment will be described below. The same reference numerals are used for the same parts in the first and second embodiments, and detailed descriptions thereof will be omitted.

The heated part 210 differs from the heated part 10 in that the capsule 50 is disposed in a substrate part 211. The heated part 210 has a substrate part 211 including an aerosol source, a wrapping paper 212 corresponding to the wrapping paper 12, and a solid member 213 that prevents the substrate part 211 from falling off from the end face on the first side of the heated part 210. The heated part 210 is connected (coupled) to the cooling part 20 by winding the cooling part 20 and the heated part 210 together using tipping paper 40. The material constituting the solid part 213 can be, for example, the same as the material constituting the solid part 13.
The heated portion 210 is formed into a cylindrical shape by winding a base material portion 211 and a solid member 213 with a wrapping paper 212. When the heated portion 210 is made of two or more members, it is preferable that the wrapping paper is wound around each of these two or more members, and then the two or more members are further wrapped with another wrapping paper.

The substrate portion 211 is filled with an aerosol source, and has the capsules 50 embedded therein.
The aerosol source filled in the base portion 211 may be, for example, the same as the aerosol source filled in the base portion 11 .

The capsule 50 is embedded, for example, in the center in the transverse section of the base material part 211. The position of the capsule 50 in the longitudinal section of the heated part 210 is preferably embedded in a position where the contents 51 do not leak out from the first end face and the second end face of the base material part 211. In other words, the capsule 50 is preferably disposed in a position where the diffusion of the contents 51 is contained in the base material part 211.
Furthermore, the capsule 50 may be embedded, for example, closer to the solid member 213 in the transverse cross section of the substrate 211. The position of the capsule 50 in the longitudinal cross section of the heated portion 210 is preferably embedded at a position where the contents 51 do not leak out from at least the end face on the second side of the substrate 211. In other words, the capsule 50 is preferably disposed at a position where the diffusion of the contents 51 is contained within the substrate 211 and the solid member 213.

In this embodiment, the pushing member 115 (see FIG. 3) of the flavor inhaler 100 is provided at a position where, when it moves into the internal space 141, it can apply a physical external force to at least a part of the area of the stick 2 where the capsule 50 is arranged. Specifically, in this embodiment, the pushing member 115 is provided at a position where, when it moves into the internal space 141, it can apply a physical external force to the base part 211 where the capsule 50 of the stick 2 is arranged. It is preferable that the position of the pushing member 115 is a position where, when it moves into the internal space 141, it can apply a physical external force to the area of the base part 211 where the capsule 50 is arranged.

As explained above, the stick 2 is a flavor inhalation stick that is heated when inserted into the flavor inhaler 100, and includes a heated portion 210 that is heated when inserted into the flavor inhaler 100, and a capsule 50 that is disposed within the heated portion 210 and releases the contents 51 when destroyed. The capsule 50 is not destroyed when either the heat from the heating portion 121 or the physical external force from the pushing member 115 is applied to it, but is partially or completely destroyed when both the heat from the heating portion 121 and the physical external force from the pushing member 115 are applied to it.

　Similar to stick 1, stick 2 can provide a flavor inhalation stick that can impart a new flavor and taste by using a capsule placed in the heated area.

The capsule 50 is disposed within the base material portion 211 .
When the capsule 50 is placed in the solid member 213, the heat applied to the capsule 50 is heat propagated from the substrate 211 heated by the heating unit 121, and the temperature in the solid member 213 becomes the same as or lower than the temperature in the substrate 211. In this embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to destroy the capsule 50.

The above-mentioned example is not limiting, and each of the multiple capsules 50 may be arranged in a different region. Specifically, the capsules 50 may be arranged in the base material 211, and the capsules 50 may also be arranged in the solid member 213. By arranging each of the multiple capsules 50 in different regions, it is possible to provide a difference in the way heat and physical external forces are applied to the capsules 50. By providing a difference in the way heat and physical external forces are applied to the capsules 50, it is possible to shift the timing at which the multiple capsules 50 are destroyed. Furthermore, by providing a difference in the way heat and physical external forces are applied to the capsules 50, it is possible to simultaneously destroy multiple capsules 50 with different destruction strengths.
In addition, the flavor inhaler 100 may be equipped with a plurality of heating units 121 and a plurality of pushing members 115, and heat and external physical force may be applied separately to each of a plurality of capsules 50 arranged in different regions.

Third Embodiment
FIG. 6 is a diagram showing a vertical cross section of the stick 3 according to the third embodiment.
The stick 3 according to the third embodiment is different from the stick 2 according to the second embodiment in that the heated portion 310 corresponds to the heated portion 210. The differences from the second embodiment will be described below. The same reference numerals are used for the same parts in the second and third embodiments, and detailed descriptions thereof will be omitted.

The heated part 310 differs from the heated part 210 in that it does not have a solid member 213. In addition, the heated part 310 has a base material part 311 including an aerosol source, and a wrapping paper 312 corresponding to the wrapping paper 212. The heated part 310 is connected (coupled) to the cooling part 20 by winding up the cooling part 20 and the heated part 310 together using tipping paper 40.
The heated portion 310 is formed into a cylindrical shape by wrapping a base material portion 311 in wrapping paper 312 .

The substrate portion 311 is filled with an aerosol source, and has the capsule 50 embedded therein. For example, the capsule 50 is embedded in the center of the substrate portion 311 in cross section.
The aerosol source filled in the base material portion 311 can be, for example, the same as the aerosol source filled in the base material portion 11 according to the first embodiment, like the base material portion 211.

The capsule 50 is embedded in the center of the cross section of the base material 311. The position of the capsule 50 in the vertical section of the heated portion 310 is preferably embedded in a position where the contents 51 do not leak out from the first end face and the second end face of the base material 311. In other words, the capsule 50 is preferably positioned in a position where the diffusion of the contents 51 is contained within the heated portion 310.

In the case of this embodiment, in the flavor inhaler 100 (see FIG. 4 ), the size and arrangement of the heating unit 121 that heats the stick 3 are appropriately changed so as to heat the entire base material unit 311. The size and arrangement of the heat insulating unit 144 correspond to the heating unit 121.
Furthermore, the pushing member 115 (see FIG. 3 ) is provided at a position where, when the pushing member 115 moves into the internal space 141, it can apply a physical external force to at least a part of the region of the stick 3 where the capsules 50 are arranged. Specifically, in the case of this embodiment, the pushing member 115 is provided at a position where, when the pushing member 115 moves into the internal space 141, it can apply a physical external force to at least a part of the region of the base material portion 311 where the capsules 50 are arranged.

As explained above, the stick 3 is a flavor inhalation stick that is heated when inserted into the flavor inhaler 100, and includes a heated portion 310 that is heated when inserted into the flavor inhaler 100, and a capsule 50 that is disposed within the heated portion 310 and releases the contents 51 when destroyed. The capsule 50 is not destroyed when either the heat from the heating portion 121 or the physical external force from the pushing member 115 is applied to it, but is partially or completely destroyed when both the heat from the heating portion 121 and the physical external force from the pushing member 115 are applied to it.

　Similar to stick 2, stick 3 can provide a flavor inhalation stick that can impart a new flavor and taste by using a capsule placed in the heated area.

Moreover, the heated portion 310 does not have a solid member 213 (see FIG. 5 ), and the capsule 50 is disposed within the substrate portion 311 .
When the heated portion 310 has the solid member 213, the size of the base material 311 in the center line direction is reduced, and the content of the aerosol source is less than the content of the aerosol source when the heated portion 310 does not have the solid member 213. In addition, the heat applied to the capsule 50 is the temperature inside the base material 311 heated by the heating portion 121. In this embodiment, it is possible to easily destroy the capsule 50 while increasing the concentration of the aerosol to be inhaled.

Fourth Embodiment
FIG. 7 is a diagram showing a vertical cross section of the stick 4 according to the fourth embodiment.
The stick 4 according to the fourth embodiment is different from the stick 1 according to the first embodiment in that the heated portion 410 corresponds to the heated portion 10. The differences from the first embodiment will be described below. The same reference numerals are used for the same parts in the first and fourth embodiments, and detailed descriptions thereof will be omitted.

The heated portion 410 differs from the heated portion 10 in that a solid member 413 corresponding to the solid member 13 is disposed on the second side of the heated portion 410. The heated portion 410 has a substrate portion 411 including an aerosol source, a wrapping paper 412 corresponding to the wrapping paper 12, and a solid member 413 that prevents the substrate portion 411 from moving to the cooling portion 20. The heated portion 410 is connected (coupled) to the cooling portion 20 by winding up the cooling portion 20 and the heated portion 410 together using tipping paper 40.
The heated portion 410 is formed into a cylindrical shape by wrapping a base material portion 411 in wrapping paper 412 .

The substrate 411 is disposed on the first side of the heated portion 410. Specifically, the end face on the first side of the substrate 411 is disposed so as to become the end face on the first side of the stick 4. It can be shown, for example, that the aerosol source filled in the substrate 411 is the same as the aerosol source filled in the substrate 11.

The solid member 413 is a member that prevents the base member 411 from moving toward the cooling unit 20, and has the capsules 50 embedded therein. For example, the capsules 50 are embedded in the center of the solid member 413 in a cross section.
The material constituting the solid member 413 may be the material constituting the solid member 13. The material constituting the solid member 413 may include a cooling element that undergoes a phase transition at the temperature inside the solid member 413 to cause heat absorption while maintaining the temperature inside the solid member 413 at a temperature that can destroy the coating 52 and volatilize the components of the contents 51. The type of the cooling element is not particularly limited, and may be, for example, a biodegradable polymer or an edible polymer. Specific examples of the cooling element include polylactic acid, polyvinyl alcohol (PVA), cellulose acetate, trehalose, maltose, sucrose, maltitol, glucose, WAX, wax, hardened oil, etc., or a combination thereof.

The capsule 50 is embedded in the center of the cross section of the solid member 413. The position of the heated portion 410 of the capsule 50 in the vertical section is preferably embedded in a position where the contents 51 do not leak out from the first end face and the second end face of the solid member 413. In other words, the capsule 50 is preferably positioned in a position where the diffusion of the contents 51 is contained within the solid member 413.

In the case of this embodiment, in the flavor inhaler 100 (see FIG. 4 ), the size and arrangement of the heating unit 121 that heats the stick 4 are appropriately changed so as to heat the entire base material unit 411. In addition, the size and arrangement of the heat insulating unit 144 correspond to the heating unit 121.
Furthermore, the pushing member 115 (see FIG. 3 ) is provided at a position where, when the pushing member 115 moves into the internal space 141, it can apply a physical external force to at least a part of the region of the stick 4 where the capsule 50 is disposed. Specifically, in the case of this embodiment, the pushing member 115 is provided at a position where, when the pushing member 115 moves into the internal space 141, it can apply a physical external force to the solid member 413 of the heated portion 410 where the capsule 50 is disposed.

As explained above, the stick 4 is a flavor inhalation stick that is heated when inserted into the flavor inhaler 100, and includes a heated portion 410 that is heated when inserted into the flavor inhaler 100, and a capsule 50 that is disposed within the heated portion 410 and releases the contents 51 when destroyed. The capsule 50 is not destroyed when either the heat from the heating portion 121 or the physical external force from the pushing member 115 is applied to it, but is partially or completely destroyed when both the heat from the heating portion 121 and the physical external force from the pushing member 115 are applied to it.

　Similar to stick 1, stick 4 can provide a flavor inhalation stick that can impart a new flavor and taste by using a capsule placed in the heated area.

Moreover, the solid member 413 in which the capsules 50 are embedded is disposed on the second side of the heated portion 410. In other words, according to the stick 4, the solid member 413 in which the capsules 50 are embedded is disposed on the second side with respect to the base portion 411.
Here, it is assumed that the heating unit 121 of the flavor inhaler 100 is in contact with the region where the base material 411 is arranged but is not in contact with the region where the solid member 413 is arranged. When the solid member 413 is arranged on the first side with respect to the base material 411, the heat applied to the capsule 50 is heat propagated from the base material 411 heated by the heating unit 121, but the air passing through the solid member 413 is air flowing in from the end face on the first side of the stick 4. On the other hand, when the solid member 413 is arranged on the second side with respect to the base material 411, the heat applied to the capsule 50 is heat propagated from the base material 411 heated by the heating unit 121, and the air passing through the solid member 413 is air that has passed through the base material 411. The temperature of the air that has passed through the base material 411 is higher than the temperature of the air that flows in from the end face on the first side of the stick 4. In this embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to destroy the capsule 50.

The above-mentioned example is not limiting, and each of the multiple capsules 50 may be arranged in a different region. Specifically, the capsules 50 may be arranged in the base material 411, and the capsules 50 may also be arranged in the solid member 413. By arranging each of the multiple capsules 50 in different regions, it is possible to provide a difference in the way heat and physical external forces are applied to the capsules 50. By providing a difference in the way heat and physical external forces are applied to the capsules 50, it is possible to shift the timing at which the multiple capsules 50 are destroyed. Furthermore, by providing a difference in the way heat and physical external forces are applied to the capsules 50, it is possible to simultaneously destroy multiple capsules 50 with different destruction strengths.
In addition, the flavor inhaler 100 may be equipped with a plurality of heating units 121 and a plurality of pushing members 115, and heat and external physical force may be applied separately to each of a plurality of capsules 50 arranged in different regions.

<Modification 1>
The non-combustion heating type flavor inhaler 100 that heats the sticks 1, 2, 3, and 4 is not limited to the above-mentioned configuration, and may include a pushing member that is inserted into the inside of the sticks 1, 2, 3, and 4 to push the capsule 50.
Fig. 8 is a diagram showing an example of the flavor inhaler 200. Fig. 8 shows a cross-sectional view of the flavor inhaler 200, and omits the internal configuration of the flavor inhaler 200 that is not normally visible to the user.
The flavor inhaler 200 according to the modified example 1 shown in Fig. 8 is different from the flavor inhaler 100 shown in Fig. 3 in that it has a pushing member 126 that corresponds to the pushing member 115. The following describes the differences from the flavor inhaler 100 shown in Fig. 3. The same reference numerals are used for the same parts in Fig. 3 and Fig. 8, and detailed descriptions thereof will be omitted.

In the example shown in FIG. 8, the flavor inhaler 200 includes a front cover 110 that buffers heat released from inside the device to the outside, a pushing member 126 that pushes the stick 1, a main body housing 120 to which the front cover 110 can be detached, and a shutter 150 that closes an insertion opening through which the stick 1 is inserted. The flavor inhaler 200 also includes a holding portion 140 that holds the stick 1, and an insertion opening 142 that connects the internal space 141 to the outside.

8, the pushing member 126 protrudes into the internal space 141. The pushing member 126 applies a physical external force to at least a part of the area of the stick 1 where the capsule 50 is arranged. Specifically, the pushing member 126 applies pressure to the capsule 50. The pushing member 126 may also come into contact with the capsule 50.
The pressing member 126 is not limited to a configuration in which it always protrudes into the internal space 141, but may be configured to be movable into the internal space 141 when a button (not shown) is pressed.

When a physical external force is applied by the pushing member 126, the capsule 50 may maintain a state in which it is deformed, for example, from a spherical shape to an elliptical shape as shown in Fig. 8. This allows stress to be continuously applied to the capsule 50 even if the physical external force is not continuously applied by the pushing member 126. In addition, the surface area of the capsule 50 exposed to heat is increased.
In addition, when a physical external force is applied by the pushing member 126, the capsule 50 may move, for example, toward the outer circumferential surface of the stick 1. This brings the capsule 50 closer to the heating unit 121 (see FIG. 4 ) and increases the temperature of the heat applied to the capsule 50.

The shape of the pushing member 126 may be changed as appropriate to match the size of the flavor inhaler 100, but it is preferable that the shape is such that a physical external force can be applied to at least a portion of the area of the stick 1 where the capsule 50 is located. From the viewpoint of ease of insertion into the inside of the stick 1, it is preferable that the pushing member 126 has a shape with a thin tip, for example.

Furthermore, the area reached by the tip of the pushing member 126 is not limited to the area coinciding with the area in which the capsule 50 is placed, but may be just before the area in which the capsule 50 is placed as long as pressure can be applied to the capsule 50.
Furthermore, when the capsule 50 is moved toward the outer circumferential surface of the stick 1 by the pushing member 126, the area reached by the tip of the pushing member 126 may be deeper than the area in which the capsule 50 is disposed. The pushing member 126 may heat the stick 1.

<Modification 2>
The flavor inhaler 100 may also include a pushing member that narrows the internal space 141 and pushes the sticks 1, 2, 3, and 4.
Fig. 9 is a diagram showing an example of a flavor inhaler 300. Fig. 9 shows a cross-sectional view of the flavor inhaler 300, and omits the internal configuration of the flavor inhaler 300 that is not normally visible to the user.
The flavor inhaler 300 shown in Fig. 9 differs from the flavor inhaler 100 shown in Fig. 3 in that it has a pushing member 127 that corresponds to the pushing member 115. The following describes the differences from the flavor inhaler 100 shown in Fig. 3. The same reference numerals are used for the same parts in Fig. 3 and Fig. 9, and detailed descriptions thereof will be omitted.

In the example shown in FIG. 9, the flavor inhaler 300 according to the second modification comprises a front cover 110 that buffers heat released from inside the device to the outside, a pushing member 127 that pushes the stick 1, a main body housing 120 to which the front cover 110 can be detached, and a shutter 150 that closes an insertion opening through which the stick 1 is inserted. The flavor inhaler 300 also comprises a holding portion 140 that holds the stick 1, and an insertion opening 142 that connects the internal space 141 to the outside.

9, the pushing member 127 narrows the internal space 141. The pushing member 127 applies a physical external force to the heated portion 10 in which the capsule 50 is disposed of the stick 1. Specifically, the pushing member 127 applies pressure to the heated portion 10 in which the capsule 50 is disposed.
It is preferable that the pressing member 127 moves into the internal space 141 when the stick 1 is held by the holding portion 140, thereby narrowing the internal space 141. The pressing member 127 may be configured to be movable into the internal space 141 when the user presses a button (not shown).

When a physical external force is applied by the pushing member 127, the capsule 50 may maintain a state in which it is deformed, for example, from a spherical shape to an elliptical shape as shown in FIG. 9. This increases the surface area of the capsule 50 exposed to heat.

The shape of the pushing member 127 may be changed as appropriate to match the size of the flavor inhaler 100, but it is preferable that the shape be such that the internal space 141 can be narrowed from the insertion opening 142 toward the area of the stick 1 where the capsule 50 is located.
The pressing member 127 may be disposed on a part of the outer periphery of the stick 1, or may be disposed so as to cover the outer periphery of the stick 1. The pressing member 127 may heat the stick 1.
