PTL 1 indicates that the aerosol generating mechanism comprises: one or more capsules in which a substance containing an aerosol generating substance that generates an aerosol when heated is encapsulated within a shell layer, the shell layer being configured to melt when heated or to be damaged by the heating element, to thereby release the aerosol generating substance that is within the shell layer; and a holding / carrying member which, before use, functions as a member for holding at least one capsule in a position in which the heating element will come into contact with or approach the at least one capsule when inserted into the heating-type smoking article, and which, when in use, functions as a member for carrying the substance containing the aerosol generating substance released from within the shell layer of the at least one capsule.CITATION LISTPATENT LITERATURE

[0003] PTL 1: JP 2022-118979 ASUMMARY OF INVENTIONTECHNICAL PROBLEM

[0004] In sticks for flavor inhalation that generate an aerosol by heating a substrate portion containing an aerosol source, capsules may be disposed in a region to which heat is applied. In a state in which the stick for flavor inhalation has been inserted into a flavor inhaler, it may be desirable to break the capsule by heat and release the contents from the capsule to impart a new flavor and taste. However, it is difficult to break the capsule by heat alone.

[0005] The objective of the present disclosure is to provide a stick for flavor inhalation and a flavor inhalation system capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.SOLUTION TO PROBLEM

[0006] The present disclosure, completed in light of this objective provides a stick for flavor inhalation that is heated by being inserted into a flavor inhaler, the stick for flavor inhalation comprising a heated portion which is heated when inserted into the flavor inhaler, and a capsule which is disposed within the heated portion and which releases contents when broken, wherein the capsule does not break when subjected to either one of the heat and a physical external force, and breaks partially or fully when subjected to both of the heat and the physical external force.

[0007] Here, a breaking strength of the capsule for breakage to the extent that the contents are released may be reduced by the application of the heat.

[0008] Further, the capsule may not break if the physical external force is applied before the heat is applied, and may break partially or fully if the physical external force is applied after the heat is applied.

[0009] Further, the amount of the contents released by the capsule may vary on the basis of the number of times the physical external force is applied.

[0010] Further, the breaking strength of the capsule for breakage to the extent that the contents are released may be reduced by the application of the physical external force.

[0011] Further, the capsule may not break if the heat is applied before the physical external force is applied, and may break partially or fully if the heat is applied after the physical external force is applied.

[0012] Further, the capsule may break partially or fully when the heat and the physical external force are applied simultaneously.

[0013] Further, the capsule may break partially or fully when the capsule is both heated to at least 100°C and subjected to a physical external force.

[0014] Further, the present disclosure, completed in light of the abovementioned objective, also provides a flavor inhalation system comprising the stick for flavor inhalation, and a flavor inhaler for heating the stick for flavor inhalation.ADVANTAGEOUS EFFECTS OF INVENTION

[0017] Embodiments of the present disclosure will be described in detail below with reference to the appended drawings. In the drawings, identical parts are indicated by identical reference signs.<First Embodiment>

[0018] Fig. 1 is a diagram showing the longitudinal cross section of a stick 1 according to a first embodiment.

[0019] A stick 1 for flavor inhalation (hereinafter sometimes referred to as 'stick') according to the first embodiment comprises 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 a centerline CL of the heated portion 10 may be referred to as the "centerline direction". The stick 1 is additionally provided with a tipping paper that is wrapped around the heated portion 10, the cooling portion 20, and the filter portion 30 arranged in the stated order in the centerline direction, thereby integrating these components. Hereinafter, one end side (the left side in fig. 1) in the centerline direction may be referred to as the first side, and the other end side (right side in fig. 1) in the centerline direction 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 opposite side to the first side, and is the end side that is held in the user's mouth for inhalation. Additionally, a cross section along the centerline direction is referred to as a "longitudinal cross section," and a cross section cut along a plane orthogonal to the centerline direction is defined as a "transverse cross section."[Flavor inhalation system]

[0020] Fig. 2 is an overall oblique view of a 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. It should be noted that in fig. 3, the internal configuration of the flavor inhaler 100, which is not normally visible to the user, is omitted.

[0021] The flavor inhalation system according to the present embodiment comprises a stick 1 according to the first embodiment and a heat-not-burn type flavor inhaler 100 that heats the heated portion 10 of the stick 1 from the outside. The stick according to the first embodiment is inserted into the heat-not-burn type flavor inhaler 100 for use.

[0022] In the example shown in fig. 2, the flavor inhaler 100 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, a pushing member 115 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that opens and closes an insertion opening 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 also comprises a holding portion 140 that holds the stick 1 and an insertion opening 142 which provides communication between an internal space 141 and the outside, and into which the stick 1 is inserted.

[0023] In fig. 2, the shutter 150 is shown to be closing the insertion opening 142. The shutter 150 has a slide mechanism, and is capable of moving along the surface of an outer casing between a first position for closing the insertion opening 142 and a second position for opening the insertion opening 142. The insertion opening 142 is opened by the user sliding the shutter 150 along a side face with a finger. As a result of the opening insertion opening 142 being opened, the stick 1 is inserted by the user into the holding portion 140 that holds the stick 1, as shown in fig. 3.

[0024] The pushing member 115 shown in fig. 3, is for example, a screw-shaped member. As shown in fig. 3, the pushing member 115 is located adjacent to the internal space 141 and is capable of moving into the internal space 141.

[0025] Upon moving into the internal space 141, the pushing member 115 applies a physical external force to at least a portion of a region of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 115, which is moved into the internal space 141 by being turned by the user, indirectly applies pressure to the capsule 50.

[0026] The pushing member 115 is not limited to a screw-shaped member, and may be any member that is capable of moving into the internal space 141. The pushing member 115 may be a member that moves into the internal space 141 by being pushed by the user, for example.

[0027] It should be noted that the means for applying a physical external force to the capsules 50 is not limited to the means described above, and known techniques may be used.

[0028] Fig. 4 is a schematic diagram showing an internal configuration example of the flavor inhaler 100.

[0029] As shown in fig. 4, the main body 130 of the flavor inhaler 100 includes a power source unit 131 for storing electric power and supplying electric power to each component of the main body 130, a sensor unit 132 for detecting various types of information relating to the main body 130, and a notification unit 133 for notifying the user of information. Furthermore, the main body 130 also includes a memory unit 134 for storing various types of 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 for controlling the overall operation within the main body 130. The main body 130 also includes a heating unit 121 for heating the stick 1 and a heat insulating portion 144 for preventing heat transfer from the heating unit 121 to other components of the main body 130. In the flavor inhaler 100, inhalation by the user is performed while the stick 1 is held in the holding portion 140.

[0030] The heating unit 121 heats the heated portion 10 of the stick 1. The heating unit 121 is formed by any material such as a metal or polyimide. For example, the heating unit 121 is configured in a film shape and is disposed so as to cover the outer periphery of the holding portion 140. When the heating unit 121 generates heat, an aerosol source contained in a substrate portion 11 of the stick 1 (see fig. 1) is heated from the outer periphery of the stick 1. The heating unit 121 generates heat when supplied with electricity from the power source unit 131. As an example, power may be supplied when the sensor unit 132 detects a prescribed user input. Inhalation by the user becomes possible when the temperature of the stick 1 heated by the heating unit 121 has reached a prescribed temperature. Thereafter, the supply of power may be stopped when a predetermined user input is detected by the sensor unit 132. As another example, power may be supplied to generate the aerosol during a period in which inhalation by the user is detected by the sensor unit 132.

[0031] The heat insulating portion 144 is disposed so as to cover at least the outer periphery of the heating unit 121. For example, the heat insulating portion 144 is configured by a vacuum heat insulating material or an aerogel heat insulating material, or the like. It should be noted that a vacuum insulating material is a heat insulating material in which a state of high vacuum is created by wrapping glass wool and silica (silicon powder), etc. in a resin film, for example, so that heat conduction by gas is as close as possible to zero.[Stick 1]

[0032] The stick 1 is a heat-not-burn type flavor inhalation article.

[0033] The transverse cross section of the stick 1 is substantially circular, and the outer diameter and size in the centerline direction can be modified as appropriate in accordance with the size of the product.[Cooling portion 20]

[0034] The cooling portion 20 is positioned adjacent to the heated portion 10 and the filter portion 30, and is a part that is formed by wrapping a sheet 21 such that the transverse cross section is hollow (a cavity), such as a cylinder. The cooling portion 20 generates an aerosol by cooling vapor generated by heating the heated portion 10. For example, the cooling portion 20 is a paper tube formed by winding a sheet 21 made of paper.

[0035] The transverse cross section of the cooling portion 20 is substantially circular, and the outer diameter thereof can be changed as appropriate in accordance with the size of the product, but is preferably approximately the same as the outer diameter of the filter 31 discussed hereinafter. It should be noted that when the transverse cross-section is not circular, the aforementioned outer diameter is applied assuming a circle having the same area as the area of the cross-section.

[0036] Although the size of the cooling portion 20 in the centerline direction can be changed as appropriate in accordance with the size of the product, it is desirable that the size be such that a good flavor can be obtained while ensuring a sufficient cooling effect, and such that losses due to adhesion of the generated vapor and aerosol to the sheet 21 can be suppressed.

[0037] The material of the sheet 21 is not particularly restricted and may, for example, be a material having pulp as the main component, a material having polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, or aluminum foil as the main component, or any combination thereof.

[0038] The cooling portion 20 has been described as a part formed by wrapping the sheet 21, but is not limited to this configuration provided that the transverse cross section is hollow. The cooling portion 20 may equally be formed, for example, by a tube of a synthetic resin or the like that already has a hollow transverse cross section.

[0039] The cooling portion 20 is provided with through-holes 60 (also referred to as a "ventilation filter (Vf)" in this technical field) which are provided in the circumferential direction and are concentric. The through-holes 60 are holes that penetrate through the sheet 21. Examples of the shape of the holes include polygonal, rounded-corner polygonal, circular, elliptical, etc. The through-holes 60 are present in a region in which air can flow in from outside the stick 1, in other words, in a region that protrudes from the opening 142 when the stick 1 is held in the holding portion 140 of the inhalation device 100.

[0040] The presence of the through-holes 60 allows the concentrations of the flavor and taste components and the aerosol that are inhaled to be adjusted. Further, the presence of the plurality of through-holes 60 allows air to flow into the cooling portion 20 from the outside during inhalation, enabling the temperature of the vapor and air flowing in from the substrate portion 11 to be lowered.

[0041] It should be noted that vapor generated by heating the substrate portion 11, with the aerosol acting as the condensation nuclei, liquefies as a result of a decrease in temperature upon coming into contact with air from the outside, and this can promote the generation of the aerosol.

[0042] If a plurality of the through-holes 60 that are present concentrically in the cooling portion 20 are treated as one group of through-holes, there may be one group of through-holes, or there may be two or more groups of through-holes.

[0043] Furthermore, if the stick 1 is of a form in which the heated portion 10, the cooling portion 20, and the filter portion 30 are wrapped with tipping paper 40, it is preferable that vent holes are provided in the tipping paper 40 in positions immediately above the through-holes 60 provided in the cooling portion 20. When manufacturing such a stick 1, the tipping paper 40 provided with vent holes overlapping the through-holes 60 may be prepared and wrapped, but, from the point of view of ease of production, it is preferable to manufacture the stick 1 without the through-holes 60, and to then form holes simultaneously penetrating through the cooling portion 20 and the tipping paper 40.[Filter portion 30]

[0044] The filter portion 30 includes a first filter 31, which is connected to the second side of the substrate portion 20, and a second filter 32, which is positioned on the second side of the first filter 31. The first filter 31 has a hollow transverse cross section and the second filter 32 has a solid transverse cross section.

[0045] The filter portion 30 is connected (linked) to the cooling portion 20 by wrapping the second side end of the cooling portion 20 and the first side end of the filter portion 30 together integrally using the tipping paper, which is discussed hereinafter. There may also be a rolling paper 33 which is wrapped between the outer peripheral surfaces of the first filter 31 and the second filter 32, and the tipping paper 40.

[0046] The transverse cross sections of the first filter 31 and the second filter 32 of the filter portion 30 are substantially circular, and the diameter of the circle and the length around the transverse cross section can be changed as appropriate in accordance with the size of the product. It should be noted that if the transverse cross section not circular, the abovementioned diameter is applied assuming a circle having the same area as the area of the transverse cross section.

[0047] The first filter 31 and the second filter 32 are not particularly restricted provided that they include a filter material and have the general functions of a filter. General functions of a filter that may be cited include, for example, reducing undesirable sensations such as stimulation and reducing nicotine and tar, and in addition, if openings corresponding to the through-holes 60 are present on the second side of the filter, adjusting the amount of air that is mixed when the aerosol, etc., is inhaled, but not all of these functions need to be provided. Furthermore, in the stick 1, which generates fewer components and tends to have a lower filling rate of the aerosol source in the substrate portion 11 than a cigarette product, important functions of the filter also lie in preventing the aerosol source 11 from falling out, while controlling a filtration function, and adjusting the ventilation resistance for imparting an appropriate ease of suction during inhalation.

[0048] The filter material constituting the first filter 31 and the second filter 32 is, for example, a filling material such as cellulose acetate fibers, nonwoven fabric, or pulp paper formed into a cylindrical shape. A paper filter filled with sheet-like pulp paper may also be used.

[0049] There is no particular restriction on the form of the rolling paper 33, which may include a seam including one or more lines of adhesive. The adhesive may comprise a hot-melt adhesive, and further, the hot-melt adhesive may comprise polyvinyl alcohol. Additionally, if the filter portion 30 consists of two or more members, it is preferable to wrap each of the two or more members with rolling paper and then further wrap them together with another rolling paper.

[0050] There is no particular restriction on the material of the rolling paper 33, and well-known materials may be used, and the rolling paper may furthermore include a filler such as calcium carbonate, etc.

[0051] Furthermore, the rolling paper 33 may be coated or uncoated, but is preferably coated with a desired material from the viewpoint of imparting functions such as strength and structural rigidity.[Tipping paper 40]

[0052] The tipping paper 40 is wrapped around 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 particular limited, and may be square or rectangular, for example.

[0053] The configuration of the tipping paper 40 is not particularly limited, and can take a general form, examples of which include those having pulp as the main component. The pulp may be made of wood pulp such as softwood pulp and hardwood pulp, or produced with an admixture of non-wood pulp that is typically used in rolling paper for smoking products, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps can be used alone or in combination of multiple types in any ratio.

[0054] In addition to the materials described above, the tipping paper 40 may also contain fillers, for example calcium carbonate from the viewpoint of improving whiteness and opacity and increasing the heating rate. In addition to the materials and fillers described above, various aids may be added to the tipping paper 40, which may also contain water-resistance improving agents, including wet strength agents (WS agents) and sizing agents.

[0055] A coating agent may be added to at least one of the two surfaces of the tipping paper 40, namely the front surface and the rear surface. There is no particular restriction on the coating agent, but a coating agent that is capable of forming a film on the surface and reducing liquid permeability is preferable.

[0056] A portion of the outer surface of the tipping paper 40 may be coated with a lip-release material. A lip-release material means a material configured for assisting in easy separation, substantially without adhesion, of the lips and the tipping paper 40 when the user holds the filter portion 30 of the stick 1 in their mouth.[Heated portion 10]

[0057] The heated portion 10 comprises the substrate portion 11 containing an aerosol source, a rolling paper 12 covering the outer periphery of the substrate portion 11, a solid member 13 preventing the substrate portion 11 falling out from the first side end surface of the heated portion 10, and the capsule 50, which releases contents 51 when a coating 52 thereof is broken. The filter portion 10 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the heated portion 10 using the tipping paper 40.

[0058] The heated portion 10 is formed into a cylindrical shape by wrapping the substrate portion 11 and the solid member 13 with the rolling paper 12. Additionally, if the heated portion 10 consists of two or more members, such as including the substrate portion 11 and the solid member 13, it is preferable to wrap each of the two or more members with the rolling paper 12 and then further wrap them together with another rolling paper 12.

[0059] The aerosol source filling the substrate portion 11 may, for example, be a tobacco-derived substance such as tobacco shreds, or processed products obtained by molding a tobacco raw material into a granular form, a sheet form, or a powder form. Furthermore, the aerosol source may also include non-tobacco-derived substances produced from plants other than tobacco (e.g., mint or herb, etc.). As an example, the aerosol source may include a fragrance. The type of fragrance is not particularly restricted, but 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 to be inhaled by a patient. It should be noted that the aerosol source is not limited to a solid, and may equally be a polyhydric alcohol such as glycerol or propylene glycol, or a liquid such as water, for example. In a state in which the stick 1 is being held in the holding portion 140, at least a portion of the substrate portion 11 is accommodated in the internal space 141 of the holding portion 140.

[0060] The size of the substrate portion 11 in the centerline direction and the aerosol source content thereof can be changed as appropriate in accordance with the size of the product.

[0061] Further, the aerosol source may include tobacco shreds, etc. The material of the tobacco shreds is not particularly restricted, and known materials such as lamina and midrib can be used. Furthermore, ground tobacco may be formed by grinding dried tobacco leaves, then homogenized using a known means and processed into a sheet (also referred to below simply as a "homogenized sheet") which is shredded. Furthermore, filling with a so-called strand type is also possible, this being obtained by shredding, substantially parallel to the centerline direction of the substrate portion 11, a homogenized sheet having a size similar to that of the substrate portion 11 in the centerline direction.

[0062] Examples of tobacco types that may be cited include yellow, Burley, orient, or native type, and other Nicotiana tabacum and Nicotiana rustica varieties, and mixtures thereof. When a mixture is used, each variety is blended as appropriate to achieve the intended taste.

[0063] The shape of the rolling paper 12 can be square or rectangular, for example. When wrapping the aerosol source cylindrically with the rolling paper 12, one end of the rolling paper 12 and the other end of the rolling paper 12 in the circumferential direction, for example, can be overlapped by about 2 mm and glued together to form a cylindrical paper tube shape, with the aerosol source 11 filled inside.

[0064] The material of the rolling paper 12 is not particularly restricted, and examples that can be cited include those having pulp as the main component. The pulp may be made of wood pulp such as softwood pulp and hardwood pulp, or produced with an admixture of non-wood pulp that is typically used in rolling paper 12 for smoking products, such as flax pulp, hemp pulp, sisal pulp, or esparto.

[0065] Types of pulp that can be used include chemical pulps obtained by means of kraft pulping, acid / neutral / alkaline sulfite pulping, and soda pulping, etc., groundwood pulps, chemigroundwood pulps, and thermomechanical pulps, etc.

[0066] The solid member 13 is a member that prevents the substrate portion 11 from falling out from the first side end face of the heated portion 10, and the capsule 50 is embedded therein. For example, the capsule 50 is embedded in the center of the transverse cross section of the solid member 13.

[0067] The transverse cross section of the solid member 13 is substantially circular, and the diameter of the circle and the length around the transverse cross section can be changed as appropriate in accordance with the size of the product. It should be noted that if the transverse cross section not circular, the abovementioned diameter is applied assuming a circle having the same area as the area of the transverse cross section.

[0068] The material constituting the solid member 13 is not particularly restricted, but is preferably a material through which the contents 51 of the capsule 50 can penetrate. For example, the material constituting the solid member 13 may be a paper filter filled with sheet-shaped pulp paper, or a filter obtained by forming a filling material such as cellulose acetate fibers, nonwoven fabric, or pulp paper into a cylindrical shape.

[0069] The capsule 50 comprises the contents 51, including a flavor and taste component, and the coating 52 that holds the contents 51. It should be noted that the contents may, for example, contain an aerosol source or may contain only an aerosol source without flavor and taste components.

[0070] The capsule 50 is a filling material that is disposed inside the heated portion 10. The position in the longitudinal cross section of the heated portion 10 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the solid member 13. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the solid member 13.

[0071] The contents 51 include, for example, a fragrance component serving as a flavor and taste component. Furthermore, the contents 51 may include a flavor component, for example, serving as a flavor and taste component.

[0072] The fragrance components are not particularly limited, and may include, for example, powdered fragrances and oil-based fragrances. Main powdered fragrances include chamomile, fenugreek, menthol, mint, cinnamon, herbs, etc., in powdered form. Main oil-based fragrances include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, mint, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, coffee, tobacco, etc. Fragrance components may be used alone or in combinations of two or more. When using powdered fragrances, the particle size is preferably 500 µm or less.

[0073] Examples of flavor components include citric acid, tartaric acid, monosodium 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. Flavor components are preferably liquid or are substantially soluble in the oral cavity.

[0074] The contents 51 may include colorants such as synthetic colorants and natural colorants in addition to flavor and taste components. Preferred colorants include food additives such as Red No. 3 and No. 106, Beta-Carotene, Copper Chlorophyllin, Gardenia Blue, Yellow No. 4, etc.

[0075] The contents 51 may further include a solvent for dissolving the flavor and taste components and the colorants. Examples of solvents include medium-chain triglycerides, glycerin, propylene glycol, water, ethanol, etc.

[0076] If 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.

[0077] Furthermore, if the contents 51 are liquid or gel-like, it is preferable that the viscosity of the contents 51 is such that the contents 51 penetrate into the solid member 13 and do not leak out from the first side end face and the second side end face of the solid member 13. Furthermore, it is preferable that the amount of liquid contents per area in the transverse cross section of the solid member 13 is such that the contents 51 penetrate sufficiently into the solid member 13 and the contents 51 do not reach the first side end face of the stick 1 and spill into the flavor inhaler 100. This makes it possible to prevent the contents 51 from bleeding out to the outside of the stick 1, while imparting a new flavor and taste when the contents 51 spread inside the solid member 13.

[0078] The coating 52 encapsulating the contents 51 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115. Here, "partially broken" means that the coating 52 is cracked or the coating 52 perforated to the extent that the contents 51 are gradually released. Also, "fully broken" means that the coating 52 is cracked or the coating is melted to the extent that the contents 51 are released all at once.

[0079] The temperature at which the coating 52 melts is not particularly limited, but is preferably 100°C or higher, for example, from the viewpoint of retaining the shape of the capsule 50 when subjected only to heat from the heating unit 121. Furthermore, the temperature at which the coating 52 melts is preferably 300°C or lower, from the viewpoint of breaking the capsule 50 when subjected to both heat from the heating unit 121 and a physical external force from the pushing member 115.

[0080] The strength of the coating 52 is such that the coating 52 breaks when subjected to both heat from the heating unit 121 and a physical external force from the pushing member 115. Also, the strength of the coating 52 is such that the coating 52 does not break if subjected only to a physical external force from the pushing member 115. Moreover, the strength of the coating 52 is such that the coating 52 does not break if, for example, pressure is applied to the region in which the capsule 50 is disposed by sandwiching the stick 1 between the thumb and the index finger of the user and pressing with the thumb and the index finger. In other words, the strength of the coating 52 is such that the coating 52 does not break when subjected to heat due to a person's body temperature and a physical external force exerted by the person.

[0081] The composition of the coating 52 is not particularly restricted, provided that the coating 52 does not break when subjected to either one of heat and a physical external force, and breaks when subjected to both of heat and a physical external force.

[0082] Examples of materials for the coating 52 include starch, dextrin, polysaccharides, agar, gellan gum, gelatin, polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene-acrylonitrile copolymer, styrene-butadiene-acrylonitrile copolymer, polyethylene, polypropylene, cellulose acetate, polyethylene terephthalate, polyamide, ethylene-acrylic acid plastic, ethylene-vinyl acetate plastic, ethylene-vinyl alcohol plastic, lipophilic materials, various natural gelling agents, etc. The coating 52 may also include fragrance components, plasticizers, colorants, etc.

[0083] Lipophilic materials include, for example, fats and oils, fatty acids, sugar fatty acid esters, hydrocarbons, aromatic hydrocarbons, chain ethers, higher fatty acid esters, higher alcohols, and hydrogenated products thereof. Fats and oils include, for example, 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, etc. Examples of sugar fatty acid esters include sucrose fatty acid esters, etc. Examples of hydrocarbons include terpenes, paraffins, beeswax, etc. Examples of hydrogenated products include hydrogenated products of fats and oils such as margarine, shortening, etc.

[0084] The composition of the coating 52 may have any one of the abovementioned materials as the main component, or may be any combination thereof.

[0085] The coating 52 of the capsule 50 breaks partially or fully when the capsule 50 is both heated to at least 100°C and subjected to a physical external force.

[0086] In the present embodiment, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released changes when heat is applied by the heating unit 121. Specifically, the breaking strength of the coating 52 of the capsule 50 for breakage to the extent that the contents 51 are released is reduced when heat is applied by the heating unit 121.

[0087] In other words, in the present embodiment, the strength of the coating 52 changes when heat is applied by the heating unit 121. Specifically, the coating 52 becomes brittle when subjected to heat by the heating unit 121.

[0088] Here, the breaking strength is the degree to which the capsule 50 does not break to the extent that the contents are released.

[0089] For example, the maximum value of stress immediately before the capsule 50 breaks may be defined as the breaking strength. The maximum stress immediately before the capsule 50 breaks can be measured using a rheometer such as the CR-3000EX-S manufactured by Sun Scientific Co., Ltd., which uses a contact for compressive strength testing. As the contact continuously descends, the capsule 50 begins to distort, generating stress on the contact.

[0090] Furthermore, for example, the temperature applied to the capsule 50 immediately before the capsule 50 breaks may be used as the breaking strength, and a value relating to the hydrophilicity or hydrophobicity of the capsule 50 coating may equally be used as the breaking strength. In addition, for example, the breaking strength may be determined on the basis of at least two of the above-mentioned matters.

[0091] For example, the coating 52 does not break if a physical external force from the pushing member 115 is applied to the capsule 50 before heat from the heating unit 121 is applied, but the coating 52 breaks if a physical external force from the pushing member 115 is applied to the capsule 50 after heat from the heating unit 121 is applied.

[0092] In addition, for example, if a physical external force from the pushing member 115 is applied to the capsule 50 before heat from the heating unit 121 is applied, the coating 52 does not break, but if heat from the heating unit 121 and a physical external force from the pushing member 115 are applied to the capsule 50 simultaneously, the coating 52 breaks.

[0093] The amount of contents 51 released when the coating 52 breaks varies on the basis of the external physical force applied to the capsule 50.

[0094] If a physical external force sufficient to break a portion of the coating 52 is applied a plurality of times to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the amount of the contents 51 still held by the coating 52 is reduced, and more of the contents 51 is released, compared to a case in which a physical external force is applied only once. Furthermore, if a gradually increasing physical external force is applied to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the contents 51 are released in such a way as to bleed out from the coating 52, making it possible to adjust the concentration of the flavor and taste provided by the capsule 50.

[0095] Furthermore, if a physical external force sufficient to break the entire coating 52 is applied at once to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the contents 51 are released forcefully from the coating 52, making it possible to increase the concentration of the flavor and taste imparted by the capsule 50.

[0096] Also, in the present embodiment, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may change due to the application of a physical external force from the pushing member 115. In particular, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of a physical external force from the pushing member 115.

[0097] For example, if heat from the heating unit 121 is applied to the capsule 50 before a physical external force from the pushing member 115 is applied, the coating 52 does not melt to the extent that the capsule is partially or fully broken, but if heat from the heating unit 121 is applied to the capsule 50 after a physical external force from the pushing member 115 is applied, the coating 52 melts and breaks.

[0098] In addition, for example, if heat from the heating unit 121 is applied to the capsule 50 before a physical external force from the pushing member 115 is applied, the coating 52 does not melt, but if heat from the heating unit 121 and a physical external force from the pushing member 115 are simultaneously applied to the capsule 50, the coating 52 melts and breaks.

[0099] In addition, the amount of contents 51 released when the coating 52 breaks may vary on the basis of the temperature of the heat applied to the capsule 50.

[0100] Additionally, in the present embodiment, the state of the contents 51 of the capsule 50 may change. Specifically, the contents 51 may be solid at room temperature, but may be changed into a liquid by the heat from the heating unit 121.

[0101] For example, the configuration may be such that the coating 52 does not break if a physical external force from the pushing member 115 is applied to the capsule 50 while the contents 51 are in a solid state, but the coating 52 breaks if a physical external force from the pushing member 115 is applied when the contents 51 have reached a liquid state due to heat from the heating unit 121. In other words, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced as a result of liquefaction of the contents 51 of the capsule 50 due to heat from the heating unit 121.

[0102] The shape of the capsule 50 is not particularly restricted, and may be spherical, cylindrical, truncated conical, or the like. A plurality of capsules 50 may also be arranged.

[0103] The capsule 50 is preferably an elastic body that deforms elastically when subjected to a physical external force, and returns to its original shape and does not generate stress when no longer subjected to the physical external force. The capsule 50 may also be a body that maintains a deformed shape obtained when subjected to a physical external force, and generates stress even when no longer subjected to the physical external force.

[0104] The method for producing the capsule 50 is not particularly limited, but it is preferable to use a dropping method capable of producing capsules with a seamless coating 52.

[0105] As explained above, the stick 1 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 210 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 10 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115. It should be noted that the stick 1 need not include the cooling portion 20 shown in fig. 1, from the viewpoint of making the size more compact in the centerline direction.

[0106] The stick 1 is inserted into the holding portion 140 of the flavor inhaler 100. After the temperature of the substrate 11 heated by means of the heating unit 121 has reached a predetermined temperature, an aerosol is generated when the user inhales. When the user inhales, vapor and aerosol are cooled in the cooling portion 20.

[0107] The heated portion 10 includes the substrate portion 11, which is filled with an aerosol source, and the solid member 13 in which the capsule 50 is disposed.

[0108] Here, we will assume a case in which the heating unit 121 of the flavor inhaler 100 comes into contact with the region in which the substrate portion 11 is disposed but does not come into contact with the region in which the solid member 13 is disposed. The capsule 50 is subjected to heat from the heating unit 121. Specifically, heat within the substrate portion 11 that has been heated by the heating unit 121 propagates to the solid member 13, and the heat from the heating unit is applied to the capsule 50.

[0109] The capsule 50 is also subjected to a physical external force from the pushing member 115. Specifically, the region of the stick 1 in which the solid member 13 is located is pushed by the pushing member 115, thereby subjecting the capsule 50 to a physical external force from the pushing member 115.

[0110] The application of both heat from the heating unit 121 and a physical external force from the pushing member 115 to the capsule 50 causes the coating 52 to break partially or fully, thereby releasing the contents 51. As a result, a new flavor and taste can be imparted to the stick 1 by the capsule 50 disposed in the heated region.

[0111] Furthermore, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of heat from the heating unit 121.

[0112] A new flavor can be imparted by the capsule 50, the breaking strength of which has been reduced by the heat from the heating unit 121.

[0113] For example, the configuration may be such that the capsule 50 does not break if a physical external force from the pushing member 115 is applied before heat from the heating unit 121 is applied, and breaks partially or fully if a physical external force from the pushing member 115 is applied after heat from the heating unit 121 has been applied.

[0114] Unintended breakage of the capsule 50 can be suppressed in comparison with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115. Furthermore, in comparison with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115, the user can inhale more of the flavor and taste components contained in the contents 51 together with the aerosol generated by heating the substrate portion 11. In addition, with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115, it is difficult to change the flavor of the aerosol while the user is inhaling. Arranging that the capsule 50 breaks when subjected to a physical external force from the pushing member 115 after having been subjected to heat from the heating unit 121 allows a new flavor to be imparted by the capsule 50 at the user's desired timing.

[0115] Furthermore, the amount of the contents 51 released by the capsule 50 may vary on the basis of the number of times a physical external force has been applied by the pushing member 115.

[0116] The user's desired concentration of the flavor and taste can be imparted on the basis of the number of times a physical external force from the pushing member 115 has been applied to the capsule 50.

[0117] Furthermore, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of a physical external force from the pushing member 115.

[0118] After the application of a physical external force, the capsule 50 can be broken by heat.

[0119] For example, the configuration may be such that the capsule 50 does not break if heat from the heating unit 121 is applied before a physical external force from the pushing member 115 is applied, and breaks partially or fully if heat from the heating unit 121 is applied after an external force from the pushing member 115 has been applied.

[0120] Specifically, the configuration may be such that the capsule 50 does not break when subjected solely to heat from the heating unit 121, but is broken partially or fully by heat from the heating unit 121 when subjected to an external force from the pushing member 115. After the application of a physical external force, the capsule 50 can be broken by heat.

[0121] In addition, the capsule 50 may break partially or fully when subjected simultaneously to heat from the heating unit 121 and a physical external force from the pushing member 115.

[0122] Heat can be used to break the capsule 50.

[0123] The capsule 50 may break partially or fully when subjected both to heat from the heating portion 121 heating the capsule 50 to 100°C or more, and to a physical external force by the pushing member 115.

[0124] Unintended breakage of the capsule 50 can be suppressed in comparison with a configuration in which the coating 52 breaks when heated to less than 100°C by heat from the heating unit 121.<Second Embodiment>

[0125] Fig. 5 is a diagram showing the longitudinal cross section of a stick 2 according to a second embodiment.

[0126] The stick 2 according to the second embodiment differs from the stick 1 according to the first embodiment in that a heated portion 210 corresponding to the heated portion 10 is different. The differences from the first embodiment will be described below. In the first embodiment and the second embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0127] The heated portion 210 differs from the heated portion 10 in that the capsule 50 is disposed within the substrate portion 211. The heated portion 210 comprises a substrate portion 211 containing an aerosol source, a rolling paper 212 corresponding to the rolling paper 12, and a solid member 213 that prevents the substrate portion 211 from falling out from the first side end face of the heated portion 210. The heated portion 210 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the filter portion 210 using the tipping paper 40. By way of example, the material constituting the solid member 213 may be identical to the material constituting the solid member 13.

[0128] The heated portion 210 is formed into a cylindrical shape by wrapping the substrate portion 211 and the solid member 213 with the rolling paper 212. Moreover, if the heated portion 210 consists of two or more members, it is preferable to wrap each of the two or more members with the rolling paper and then further wrap them together with another rolling paper.

[0129] The substrate portion 211 is filled with an aerosol source, and the capsule 50 is embedded therein.

[0130] By way of example, the aerosol source filling the substrate portion 211 may be identical to the aerosol source filling the substrate portion 11.

[0131] The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 211, for example. The position in the longitudinal cross section of the heated portion 210 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the substrate portion 211. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the substrate portion 211.

[0132] Furthermore, the capsule 50 may equally be embedded toward the solid member 213 in the transverse cross section of the substrate portion 211, for example. The position in the longitudinal cross section of the heated portion 210 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from at least the second side end face of the substrate portion 211. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the substrate portion 211 and the solid member 213.

[0133] In the case of the present embodiment, the pushing member 115 of the flavor inhaler 100 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 2 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to the substrate portion 211 of the stick 2 in which the capsule 50 is disposed. The position of the pushing member 115 is preferably a position in which, when moved into the internal space 141, a physical external force can be applied to the region of the substrate portion 211 in which the capsule 50 is disposed.

[0134] As explained above, the stick 2 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 210 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 10 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0135] According to the stick 2, similarly to the stick 1, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0136] Furthermore, the capsule 50 is disposed within the substrate portion 211.

[0137] When the capsule 50 is disposed within the solid member 213, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 211 heated by the heating unit 121, and the temperature within the solid member 213 is the same as the temperature within the substrate portion 211 or is lower than the temperature within the substrate portion 211. In the present embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to break the capsule 50.

[0138] The present disclosure is not limited to the above examples, and a plurality of capsules 50 may each be disposed in a different region. Specifically, a capsule 50 may be disposed within the substrate portion 211 and a capsule 50 may also be dispose within the solid member 213. By disposing each of a plurality of capsules 50 in a different region, it is possible to provide differences between the ways heat and physical external force are applied to the capsules 50. Providing differences between the ways heat and physical external force are applied to the capsules 50 allows the timings at which the plurality of capsules 50 are broken to be staggered. Furthermore, providing differences between the ways heat and physical external force are applied to the capsules 50 allows a plurality of capsules 50 having different breaking strengths to be broken simultaneously.

[0139] It should be noted that the flavor inhaler 100 may be provided with a plurality of heating units 121 and a plurality of pushing members 115, and heat and physical external force may be applied separately to each of the plurality of capsules 50 disposed in the different regions.<Third Embodiment>

[0140] Fig. 6 is a diagram showing the longitudinal cross section of a stick 3 according to a third embodiment.

[0141] The stick 3 according to the third embodiment differs from the stick 2 according to the second embodiment in that a heated portion 310 corresponding to the heated portion 210 is different. The differences from the second embodiment will be described below. In the second embodiment and the third embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0142] The heated portion 310 differs from the heated portion 210 by not including the solid member 213. Furthermore, the heated portion 310 includes a substrate portion 311 containing an aerosol source and a rolling paper 312 corresponding to the rolling paper 212. The filter portion 310 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the filter portion 310 using the tipping paper 40.

[0143] The heated portion 310 is formed in a cylindrical shape by wrapping the substrate portion 311 with rolling paper 312.

[0144] The substrate portion 311 is filled with an aerosol source and the capsule 50 is embedded therein. The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 311, for example.

[0145] By way of example, the aerosol source filling the substrate portion 311 may be identical to the aerosol source filling the substrate portion 11 according to the first embodiment, as is the case with the substrate portion 211.

[0146] The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 311. The position in the longitudinal cross section of the heated portion 310 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the substrate portion 311. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the heated portion 310.

[0147] In the case of the present embodiment, in the flavor inhaler 100 (see fig. 4), the size and placement of the heating unit 121 for heating the stick 3 are modified appropriately to heat the entire substrate portion 311. Furthermore, the size and placement of the heat insulating portion 144 correspond to those of the heating unit 121.

[0148] In addition, the pushing member 115 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 3 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the substrate portion 311 in which the capsule 50 is disposed.

[0149] As explained above, the stick 3 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 310 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 310 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0150] According to the stick 3, similarly to the stick 2, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0151] Furthermore, the heated portion 310 does not include a solid member 213 (see fig. 5) and the capsule 50 is disposed within the substrate portion 311.

[0152] In a case in which the heated portion 310 includes the solid member 213, the size of the substrate portion 311 in the centerline direction is reduced, and the aerosol source content is lower than the aerosol source content for a case in which the heated portion 310 does not include a solid member 213. Also, the heat applied to the capsule 50 is the temperature within the substrate portion 311 heated by the heating unit 121. In the present embodiment, breaking of the capsule 50 can be facilitated while increasing the concentration of aerosol to be inhaled.<Fourth Embodiment>

[0153] Fig. 7 is a diagram showing the longitudinal cross section of a stick 4 according to a fourth embodiment.

[0154] The stick 4 according to the fourth embodiment differs from the stick 1 according to the first embodiment in that a heated portion 410 corresponding to the heated portion 10 is different. The differences from the first embodiment will be described below. In the first embodiment and the fourth embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0155] 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 includes a substrate portion 411 containing an aerosol source, a rolling paper 412 corresponding to the rolling paper 12, and the solid member 413, which prevents movement of the substrate portion 411 toward the cooling portion 20. The heated portion 410 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the heated portion 310 using the tipping paper 40.

[0156] The substrate portion 410 is formed in a cylindrical shape by wrapping the substrate portion 411 with the rolling paper 412.

[0157] The substrate portion 411 is disposed on the first side of the heated portion 410. Specifically, the first side end face of the substrate portion 411 is disposed so as to become the first side end face of the stick 4. By way of example, the aerosol source filling the substrate portion 411 may be identical to the aerosol source filling the substrate portion 11.

[0158] The solid member 413 is a member that prevents movement of the substrate portion 411 toward the cooling portion 20, and the capsule 50 is embedded therein. For example, the capsule 50 is embedded in the center of the transverse cross section of the solid member 413.

[0159] Also, by way of example, the material constituting the solid member 413 may be the material constituting the solid member 13. Furthermore, the material constituting the solid member 413 may contain a cooling element that undergoes a phase transition at the temperature within the solid member 413 to absorb heat while maintaining the temperature within the solid member 413 at a temperature at which the coating 52 can be broken and the components of the contents 51 can be volatilized. The type of the cooling element is not particularly limited, and it may, for example, be 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, cured oil, etc., or combinations thereof.

[0160] The capsule 50 is embedded in the center of the transverse cross section of the solid member 413. The position in the longitudinal cross section of the heated portion 410 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the solid member 413. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the solid member 413.

[0161] In the case of the present embodiment, in the flavor inhaler 100 (see fig. 4), the size and placement of the heating unit 121 for heating the stick 4 are modified appropriately to heat the entire substrate portion 411. Furthermore, the size and placement of the heat insulating portion 144 correspond to those of the heating unit 121.

[0162] In addition, the pushing member 115 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 4 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to the solid member 413 of the heated portion 410 in which the capsule 50 is disposed.

[0163] As explained above, the stick 4 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 410 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 410 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0164] According to the stick 4, similarly to the stick 1, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0165] Furthermore, the solid member 413 in which the capsule 50 is 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 capsule 50 is embedded is disposed on the second side relative to the substrate portion 411.

[0166] Here, we will assume a case in which the heating unit 121 of the flavor inhaler 100 comes into contact with the region in which the substrate portion 411 is disposed but does not come into contact with the region in which the solid member 413 is disposed. In a case in which the solid member 413 is disposed on the first side relative to the substrate portion 411, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 411 heated by the heating unit 121, while air passing through the solid member 413 is air flowing in from the first side end face of the stick 4. Meanwhile, in a case in which the solid member 413 is disposed on the second side relative to the substrate portion 411, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 411 heated by the heating unit 121, and the air passing through the solid member 413 is air that has passed through the substrate portion 411. The temperature of the air that has passed through the substrate portion 411 is higher than the temperature of the air that flows in from the first side end face of the stick 4. In the present embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to break the capsule 50.

[0167] The present disclosure is not limited to the above examples, and a plurality of capsules 50 may each be disposed in a different region. Specifically, a capsule 50 may be disposed within the substrate portion 411 and a capsule 50 may also be dispose within the solid member 413. By disposing each of a plurality of capsules 50 in a different region, it is possible to provide differences between the ways heat and physical external force are applied to the capsules 50. Providing differences between the ways heat and physical external force are applied to the capsules 50 allows the timings at which the plurality of capsules 50 are broken to be staggered. Furthermore, providing differences between the ways heat and physical external force are applied to the capsules 50 allows a plurality of capsules 50 having different breaking strengths to be broken simultaneously.

[0168] It should be noted that the flavor inhaler 100 may be provided with a plurality of heating units 121 and a plurality of pushing members 115, and heat and physical external force may be applied separately to each of the plurality of capsules 50 disposed in the different regions.<Modified example 1>

[0169] The heat-not-burn type flavor inhaler 100 for heating the stick 1, 2, 3, 4 is not limited to the configuration discussed hereinabove, and may include a pushing member that is inserted into the inside of the stick 1, 2, 3, 4 to push the capsule 50.

[0170] Fig. 8 is a diagram showing an example of a flavor inhaler 200. Fig. 8 shows a cross-sectional view of the flavor inhaler 200, and the internal configuration of the flavor inhaler 200, which is normally not visible to a user, is omitted.

[0171] The flavor inhaler 200 according to the modified example 1 shown in fig. 8 differs from the flavor inhaler 100 shown in fig. 3 in that a pushing member 126 corresponding to the pushing member 115 is different. The differences from the flavor inhaler 100 shown in fig. 3 will be described below. The same reference signs are used for the same components in fig. 3 and fig. 9, and detailed descriptions thereof are omitted.

[0172] In the example shown in fig. 8, the flavor inhaler 200 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, a pushing member 126 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that closes an insertion opening into which the stick 1 is inserted. The flavor inhaler 200 also comprises a holding portion 140 that holds the stick 1 and an insertion opening 142 that provides communication between the internal space 141 and the outside.

[0173] As shown in fig. 8, the pushing member 126 protrudes into the internal space 141. The pushing member 126 applies a physical external force to at least a portion of the region of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 126 applies pressure to the capsule 50. The pushing member 126 may equally come into contact with the capsule 50.

[0174] It should be noted that the pushing member 126 is not limited to a form in which it always protrudes into the internal space 141, and may adopt a form allowing it to move into the internal space 141 when a button, which is not shown, is depressed.

[0175] When a physical external force has been applied by the pushing member 126, the capsule 50 may remain 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 pressing member 126 does not continuously apply a physical external force. This also has the aim of increasing the surface area of the capsule 50 that is exposed to heat.

[0176] Additionally, when subjected to a physical external force from the pushing member 126, the capsule 50 may move toward the outer peripheral surface of the stick 1, for example. This brings the capsule 50 closer to the heating unit 121 (see fig. 4), with the aim of increasing the temperature of the heat applied to the capsule 50.

[0177] The shape of the pushing member 126 may be modified as appropriate in accordance with the size of the flavor inhaler 100, but is preferably a shape that enables a physical external force to be applied to at least a portion of the region of the stick 1 in which the capsule 50 is disposed. The shape of the pushing member 126 is preferably a shape having a narrow tip, for example, from the viewpoint of ease of insertion into the interior of the stick 1.

[0178] Also, the region reached by the tip of the pushing member 126 is not limited to a region that coincides with the region in which the capsule 50 is disposed, and may be a region ahead of the region in which the capsule 50 is positioned, provided that pressure can be applied to the capsule 50.

[0179] Furthermore, in a case in which the capsule 50 is moved by the pushing member 126 toward the outer peripheral surface of the stick 1, the region reached by the tip of the pushing member 126 may be deeper than the region in which the capsule 50 is disposed. Moreover, the pushing member 126 may heat the stick 1.<Modified example 2>

[0180] In addition, the flavor inhaler 100 may include a pushing member that narrows the internal space 141 and pushes the stick 1, 2, 3, 4.

[0181] 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 the internal configuration of the flavor inhaler 300, which is normally not visible to a user, is omitted.

[0182] The flavor inhaler 300 shown in fig. 9 differs from the flavor inhaler 100 shown in fig. 3 in that a pushing member 127 corresponding to the pushing member 115 is different. The differences from the flavor inhaler 100 shown in fig. 3 will be described below. The same reference signs are used for the same components in fig. 3 and fig. 9, and detailed descriptions thereof are omitted.

[0183] In the example shown in fig. 9, the flavor inhaler 300 according to the modified example 2 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, the pushing member 127 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that closes an insertion opening into 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 provides communication between the internal space 141 and the outside.

[0184] As shown in fig. 9, the pushing member 127 narrows the internal space 141. The pushing member 127 applies a physical external force to the heated portion 10 of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 127 applies pressure to the heated portion 10 in which the capsule 50 is disposed.

[0185] It should be noted that the pushing member 127 preferably moves into the internal space 141, thereby narrowing the internal space 141, when the stick 1 is held in the holding portion 140. Furthermore, the pushing member 127 may have a form that allows it to move into the internal space 141 when a button, which is not shown, is depressed by the user.

[0186] When a physical external force has been applied by the pushing member 127, the capsule 50 may remain deformed, for example from a spherical shape to an elliptical shape, as shown in fig. 9. This has the aim of increasing the surface area of the capsule 50 that is exposed to heat.

[0187] The shape of the pushing member 127 may be modified as appropriate in accordance with the size of the flavor inhaler 100, but is preferably a shape that allows the internal space 141 to be narrowed from the insertion opening 142 toward the region of the stick 1 in which the capsule 50 is disposed.

[0188] The pushing member 127 may be disposed on a portion of the outer periphery of the stick 1 or may be disposed so as to cover the outer periphery of the stick 1. Moreover, the pushing member 127 may heat the stick 1.<Summary>

[0017] Embodiments of the present disclosure will be described in detail below with reference to the appended drawings. In the drawings, identical parts are indicated by identical reference signs.<First Embodiment>

[0018] Fig. 1 is a diagram showing the longitudinal cross section of a stick 1 according to a first embodiment.

[0019] A stick 1 for flavor inhalation (hereinafter sometimes referred to as 'stick') according to the first embodiment comprises 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 a centerline CL of the heated portion 10 may be referred to as the "centerline direction". The stick 1 is additionally provided with a tipping paper that is wrapped around the heated portion 10, the cooling portion 20, and the filter portion 30 arranged in the stated order in the centerline direction, thereby integrating these components. Hereinafter, one end side (the left side in fig. 1) in the centerline direction may be referred to as the first side, and the other end side (right side in fig. 1) in the centerline direction 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 opposite side to the first side, and is the end side that is held in the user's mouth for inhalation. Additionally, a cross section along the centerline direction is referred to as a "longitudinal cross section," and a cross section cut along a plane orthogonal to the centerline direction is defined as a "transverse cross section."[Flavor inhalation system]

[0020] Fig. 2 is an overall oblique view of a 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. It should be noted that in fig. 3, the internal configuration of the flavor inhaler 100, which is not normally visible to the user, is omitted.

[0021] The flavor inhalation system according to the present embodiment comprises a stick 1 according to the first embodiment and a heat-not-burn type flavor inhaler 100 that heats the heated portion 10 of the stick 1 from the outside. The stick according to the first embodiment is inserted into the heat-not-burn type flavor inhaler 100 for use.

[0022] In the example shown in fig. 2, the flavor inhaler 100 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, a pushing member 115 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that opens and closes an insertion opening 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 also comprises a holding portion 140 that holds the stick 1 and an insertion opening 142 which provides communication between an internal space 141 and the outside, and into which the stick 1 is inserted.

[0023] In fig. 2, the shutter 150 is shown to be closing the insertion opening 142. The shutter 150 has a slide mechanism, and is capable of moving along the surface of an outer casing between a first position for closing the insertion opening 142 and a second position for opening the insertion opening 142. The insertion opening 142 is opened by the user sliding the shutter 150 along a side face with a finger. As a result of the opening insertion opening 142 being opened, the stick 1 is inserted by the user into the holding portion 140 that holds the stick 1, as shown in fig. 3.

[0024] The pushing member 115 shown in fig. 3, is for example, a screw-shaped member. As shown in fig. 3, the pushing member 115 is located adjacent to the internal space 141 and is capable of moving into the internal space 141.

[0025] Upon moving into the internal space 141, the pushing member 115 applies a physical external force to at least a portion of a region of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 115, which is moved into the internal space 141 by being turned by the user, indirectly applies pressure to the capsule 50.

[0026] The pushing member 115 is not limited to a screw-shaped member, and may be any member that is capable of moving into the internal space 141. The pushing member 115 may be a member that moves into the internal space 141 by being pushed by the user, for example.

[0027] It should be noted that the means for applying a physical external force to the capsules 50 is not limited to the means described above, and known techniques may be used.

[0028] Fig. 4 is a schematic diagram showing an internal configuration example of the flavor inhaler 100.

[0029] As shown in fig. 4, the main body 130 of the flavor inhaler 100 includes a power source unit 131 for storing electric power and supplying electric power to each component of the main body 130, a sensor unit 132 for detecting various types of information relating to the main body 130, and a notification unit 133 for notifying the user of information. Furthermore, the main body 130 also includes a memory unit 134 for storing various types of 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 for controlling the overall operation within the main body 130. The main body 130 also includes a heating unit 121 for heating the stick 1 and a heat insulating portion 144 for preventing heat transfer from the heating unit 121 to other components of the main body 130. In the flavor inhaler 100, inhalation by the user is performed while the stick 1 is held in the holding portion 140.

[0030] The heating unit 121 heats the heated portion 10 of the stick 1. The heating unit 121 is formed by any material such as a metal or polyimide. For example, the heating unit 121 is configured in a film shape and is disposed so as to cover the outer periphery of the holding portion 140. When the heating unit 121 generates heat, an aerosol source contained in a substrate portion 11 of the stick 1 (see fig. 1) is heated from the outer periphery of the stick 1. The heating unit 121 generates heat when supplied with electricity from the power source unit 131. As an example, power may be supplied when the sensor unit 132 detects a prescribed user input. Inhalation by the user becomes possible when the temperature of the stick 1 heated by the heating unit 121 has reached a prescribed temperature. Thereafter, the supply of power may be stopped when a predetermined user input is detected by the sensor unit 132. As another example, power may be supplied to generate the aerosol during a period in which inhalation by the user is detected by the sensor unit 132.

[0031] The heat insulating portion 144 is disposed so as to cover at least the outer periphery of the heating unit 121. For example, the heat insulating portion 144 is configured by a vacuum heat insulating material or an aerogel heat insulating material, or the like. It should be noted that a vacuum insulating material is a heat insulating material in which a state of high vacuum is created by wrapping glass wool and silica (silicon powder), etc. in a resin film, for example, so that heat conduction by gas is as close as possible to zero.[Stick 1]

[0032] The stick 1 is a heat-not-burn type flavor inhalation article.

[0033] The transverse cross section of the stick 1 is substantially circular, and the outer diameter and size in the centerline direction can be modified as appropriate in accordance with the size of the product.[Cooling portion 20]

[0034] The cooling portion 20 is positioned adjacent to the heated portion 10 and the filter portion 30, and is a part that is formed by wrapping a sheet 21 such that the transverse cross section is hollow (a cavity), such as a cylinder. The cooling portion 20 generates an aerosol by cooling vapor generated by heating the heated portion 10. For example, the cooling portion 20 is a paper tube formed by winding a sheet 21 made of paper.

[0035] The transverse cross section of the cooling portion 20 is substantially circular, and the outer diameter thereof can be changed as appropriate in accordance with the size of the product, but is preferably approximately the same as the outer diameter of the filter 31 discussed hereinafter. It should be noted that when the transverse cross-section is not circular, the aforementioned outer diameter is applied assuming a circle having the same area as the area of the cross-section.

[0036] Although the size of the cooling portion 20 in the centerline direction can be changed as appropriate in accordance with the size of the product, it is desirable that the size be such that a good flavor can be obtained while ensuring a sufficient cooling effect, and such that losses due to adhesion of the generated vapor and aerosol to the sheet 21 can be suppressed.

[0037] The material of the sheet 21 is not particularly restricted and may, for example, be a material having pulp as the main component, a material having polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, or aluminum foil as the main component, or any combination thereof.

[0038] The cooling portion 20 has been described as a part formed by wrapping the sheet 21, but is not limited to this configuration provided that the transverse cross section is hollow. The cooling portion 20 may equally be formed, for example, by a tube of a synthetic resin or the like that already has a hollow transverse cross section.

[0039] The cooling portion 20 is provided with through-holes 60 (also referred to as a "ventilation filter (Vf)" in this technical field) which are provided in the circumferential direction and are concentric. The through-holes 60 are holes that penetrate through the sheet 21. Examples of the shape of the holes include polygonal, rounded-corner polygonal, circular, elliptical, etc. The through-holes 60 are present in a region in which air can flow in from outside the stick 1, in other words, in a region that protrudes from the opening 142 when the stick 1 is held in the holding portion 140 of the inhalation device 100.

[0040] The presence of the through-holes 60 allows the concentrations of the flavor and taste components and the aerosol that are inhaled to be adjusted. Further, the presence of the plurality of through-holes 60 allows air to flow into the cooling portion 20 from the outside during inhalation, enabling the temperature of the vapor and air flowing in from the substrate portion 11 to be lowered.

[0041] It should be noted that vapor generated by heating the substrate portion 11, with the aerosol acting as the condensation nuclei, liquefies as a result of a decrease in temperature upon coming into contact with air from the outside, and this can promote the generation of the aerosol.

[0042] If a plurality of the through-holes 60 that are present concentrically in the cooling portion 20 are treated as one group of through-holes, there may be one group of through-holes, or there may be two or more groups of through-holes.

[0043] Furthermore, if the stick 1 is of a form in which the heated portion 10, the cooling portion 20, and the filter portion 30 are wrapped with tipping paper 40, it is preferable that vent holes are provided in the tipping paper 40 in positions immediately above the through-holes 60 provided in the cooling portion 20. When manufacturing such a stick 1, the tipping paper 40 provided with vent holes overlapping the through-holes 60 may be prepared and wrapped, but, from the point of view of ease of production, it is preferable to manufacture the stick 1 without the through-holes 60, and to then form holes simultaneously penetrating through the cooling portion 20 and the tipping paper 40.[Filter portion 30]

[0044] The filter portion 30 includes a first filter 31, which is connected to the second side of the substrate portion 20, and a second filter 32, which is positioned on the second side of the first filter 31. The first filter 31 has a hollow transverse cross section and the second filter 32 has a solid transverse cross section.

[0045] The filter portion 30 is connected (linked) to the cooling portion 20 by wrapping the second side end of the cooling portion 20 and the first side end of the filter portion 30 together integrally using the tipping paper, which is discussed hereinafter. There may also be a rolling paper 33 which is wrapped between the outer peripheral surfaces of the first filter 31 and the second filter 32, and the tipping paper 40.

[0046] The transverse cross sections of the first filter 31 and the second filter 32 of the filter portion 30 are substantially circular, and the diameter of the circle and the length around the transverse cross section can be changed as appropriate in accordance with the size of the product. It should be noted that if the transverse cross section not circular, the abovementioned diameter is applied assuming a circle having the same area as the area of the transverse cross section.

[0047] The first filter 31 and the second filter 32 are not particularly restricted provided that they include a filter material and have the general functions of a filter. General functions of a filter that may be cited include, for example, reducing undesirable sensations such as stimulation and reducing nicotine and tar, and in addition, if openings corresponding to the through-holes 60 are present on the second side of the filter, adjusting the amount of air that is mixed when the aerosol, etc., is inhaled, but not all of these functions need to be provided. Furthermore, in the stick 1, which generates fewer components and tends to have a lower filling rate of the aerosol source in the substrate portion 11 than a cigarette product, important functions of the filter also lie in preventing the aerosol source 11 from falling out, while controlling a filtration function, and adjusting the ventilation resistance for imparting an appropriate ease of suction during inhalation.

[0048] The filter material constituting the first filter 31 and the second filter 32 is, for example, a filling material such as cellulose acetate fibers, nonwoven fabric, or pulp paper formed into a cylindrical shape. A paper filter filled with sheet-like pulp paper may also be used.

[0049] There is no particular restriction on the form of the rolling paper 33, which may include a seam including one or more lines of adhesive. The adhesive may comprise a hot-melt adhesive, and further, the hot-melt adhesive may comprise polyvinyl alcohol. Additionally, if the filter portion 30 consists of two or more members, it is preferable to wrap each of the two or more members with rolling paper and then further wrap them together with another rolling paper.

[0050] There is no particular restriction on the material of the rolling paper 33, and well-known materials may be used, and the rolling paper may furthermore include a filler such as calcium carbonate, etc.

[0051] Furthermore, the rolling paper 33 may be coated or uncoated, but is preferably coated with a desired material from the viewpoint of imparting functions such as strength and structural rigidity.[Tipping paper 40]

[0052] The tipping paper 40 is wrapped around 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 particular limited, and may be square or rectangular, for example.

[0053] The configuration of the tipping paper 40 is not particularly limited, and can take a general form, examples of which include those having pulp as the main component. The pulp may be made of wood pulp such as softwood pulp and hardwood pulp, or produced with an admixture of non-wood pulp that is typically used in rolling paper for smoking products, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps can be used alone or in combination of multiple types in any ratio.

[0054] In addition to the materials described above, the tipping paper 40 may also contain fillers, for example calcium carbonate from the viewpoint of improving whiteness and opacity and increasing the heating rate. In addition to the materials and fillers described above, various aids may be added to the tipping paper 40, which may also contain water-resistance improving agents, including wet strength agents (WS agents) and sizing agents.

[0055] A coating agent may be added to at least one of the two surfaces of the tipping paper 40, namely the front surface and the rear surface. There is no particular restriction on the coating agent, but a coating agent that is capable of forming a film on the surface and reducing liquid permeability is preferable.

[0056] A portion of the outer surface of the tipping paper 40 may be coated with a lip-release material. A lip-release material means a material configured for assisting in easy separation, substantially without adhesion, of the lips and the tipping paper 40 when the user holds the filter portion 30 of the stick 1 in their mouth.[Heated portion 10]

[0057] The heated portion 10 comprises the substrate portion 11 containing an aerosol source, a rolling paper 12 covering the outer periphery of the substrate portion 11, a solid member 13 preventing the substrate portion 11 falling out from the first side end surface of the heated portion 10, and the capsule 50, which releases contents 51 when a coating 52 thereof is broken. The filter portion 10 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the heated portion 10 using the tipping paper 40.

[0058] The heated portion 10 is formed into a cylindrical shape by wrapping the substrate portion 11 and the solid member 13 with the rolling paper 12. Additionally, if the heated portion 10 consists of two or more members, such as including the substrate portion 11 and the solid member 13, it is preferable to wrap each of the two or more members with the rolling paper 12 and then further wrap them together with another rolling paper 12.

[0059] The aerosol source filling the substrate portion 11 may, for example, be a tobacco-derived substance such as tobacco shreds, or processed products obtained by molding a tobacco raw material into a granular form, a sheet form, or a powder form. Furthermore, the aerosol source may also include non-tobacco-derived substances produced from plants other than tobacco (e.g., mint or herb, etc.). As an example, the aerosol source may include a fragrance. The type of fragrance is not particularly restricted, but 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 to be inhaled by a patient. It should be noted that the aerosol source is not limited to a solid, and may equally be a polyhydric alcohol such as glycerol or propylene glycol, or a liquid such as water, for example. In a state in which the stick 1 is being held in the holding portion 140, at least a portion of the substrate portion 11 is accommodated in the internal space 141 of the holding portion 140.

[0060] The size of the substrate portion 11 in the centerline direction and the aerosol source content thereof can be changed as appropriate in accordance with the size of the product.

[0061] Further, the aerosol source may include tobacco shreds, etc. The material of the tobacco shreds is not particularly restricted, and known materials such as lamina and midrib can be used. Furthermore, ground tobacco may be formed by grinding dried tobacco leaves, then homogenized using a known means and processed into a sheet (also referred to below simply as a "homogenized sheet") which is shredded. Furthermore, filling with a so-called strand type is also possible, this being obtained by shredding, substantially parallel to the centerline direction of the substrate portion 11, a homogenized sheet having a size similar to that of the substrate portion 11 in the centerline direction.

[0062] Examples of tobacco types that may be cited include yellow, Burley, orient, or native type, and other Nicotiana tabacum and Nicotiana rustica varieties, and mixtures thereof. When a mixture is used, each variety is blended as appropriate to achieve the intended taste.

[0063] The shape of the rolling paper 12 can be square or rectangular, for example. When wrapping the aerosol source cylindrically with the rolling paper 12, one end of the rolling paper 12 and the other end of the rolling paper 12 in the circumferential direction, for example, can be overlapped by about 2 mm and glued together to form a cylindrical paper tube shape, with the aerosol source 11 filled inside.

[0064] The material of the rolling paper 12 is not particularly restricted, and examples that can be cited include those having pulp as the main component. The pulp may be made of wood pulp such as softwood pulp and hardwood pulp, or produced with an admixture of non-wood pulp that is typically used in rolling paper 12 for smoking products, such as flax pulp, hemp pulp, sisal pulp, or esparto.

[0065] Types of pulp that can be used include chemical pulps obtained by means of kraft pulping, acid / neutral / alkaline sulfite pulping, and soda pulping, etc., groundwood pulps, chemigroundwood pulps, and thermomechanical pulps, etc.

[0066] The solid member 13 is a member that prevents the substrate portion 11 from falling out from the first side end face of the heated portion 10, and the capsule 50 is embedded therein. For example, the capsule 50 is embedded in the center of the transverse cross section of the solid member 13.

[0067] The transverse cross section of the solid member 13 is substantially circular, and the diameter of the circle and the length around the transverse cross section can be changed as appropriate in accordance with the size of the product. It should be noted that if the transverse cross section not circular, the abovementioned diameter is applied assuming a circle having the same area as the area of the transverse cross section.

[0068] The material constituting the solid member 13 is not particularly restricted, but is preferably a material through which the contents 51 of the capsule 50 can penetrate. For example, the material constituting the solid member 13 may be a paper filter filled with sheet-shaped pulp paper, or a filter obtained by forming a filling material such as cellulose acetate fibers, nonwoven fabric, or pulp paper into a cylindrical shape.

[0069] The capsule 50 comprises the contents 51, including a flavor and taste component, and the coating 52 that holds the contents 51. It should be noted that the contents may, for example, contain an aerosol source or may contain only an aerosol source without flavor and taste components.

[0070] The capsule 50 is a filling material that is disposed inside the heated portion 10. The position in the longitudinal cross section of the heated portion 10 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the solid member 13. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the solid member 13.

[0071] The contents 51 include, for example, a fragrance component serving as a flavor and taste component. Furthermore, the contents 51 may include a flavor component, for example, serving as a flavor and taste component.

[0072] The fragrance components are not particularly limited, and may include, for example, powdered fragrances and oil-based fragrances. Main powdered fragrances include chamomile, fenugreek, menthol, mint, cinnamon, herbs, etc., in powdered form. Main oil-based fragrances include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, mint, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, coffee, tobacco, etc. Fragrance components may be used alone or in combinations of two or more. When using powdered fragrances, the particle size is preferably 500 µm or less.

[0073] Examples of flavor components include citric acid, tartaric acid, monosodium 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. Flavor components are preferably liquid or are substantially soluble in the oral cavity.

[0074] The contents 51 may include colorants such as synthetic colorants and natural colorants in addition to flavor and taste components. Preferred colorants include food additives such as Red No. 3 and No. 106, Beta-Carotene, Copper Chlorophyllin, Gardenia Blue, Yellow No. 4, etc.

[0075] The contents 51 may further include a solvent for dissolving the flavor and taste components and the colorants. Examples of solvents include medium-chain triglycerides, glycerin, propylene glycol, water, ethanol, etc.

[0076] If 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.

[0077] Furthermore, if the contents 51 are liquid or gel-like, it is preferable that the viscosity of the contents 51 is such that the contents 51 penetrate into the solid member 13 and do not leak out from the first side end face and the second side end face of the solid member 13. Furthermore, it is preferable that the amount of liquid contents per area in the transverse cross section of the solid member 13 is such that the contents 51 penetrate sufficiently into the solid member 13 and the contents 51 do not reach the first side end face of the stick 1 and spill into the flavor inhaler 100. This makes it possible to prevent the contents 51 from bleeding out to the outside of the stick 1, while imparting a new flavor and taste when the contents 51 spread inside the solid member 13.

[0078] The coating 52 encapsulating the contents 51 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115. Here, "partially broken" means that the coating 52 is cracked or the coating 52 perforated to the extent that the contents 51 are gradually released. Also, "fully broken" means that the coating 52 is cracked or the coating is melted to the extent that the contents 51 are released all at once.

[0079] The temperature at which the coating 52 melts is not particularly limited, but is preferably 100°C or higher, for example, from the viewpoint of retaining the shape of the capsule 50 when subjected only to heat from the heating unit 121. Furthermore, the temperature at which the coating 52 melts is preferably 300°C or lower, from the viewpoint of breaking the capsule 50 when subjected to both heat from the heating unit 121 and a physical external force from the pushing member 115.

[0080] The strength of the coating 52 is such that the coating 52 breaks when subjected to both heat from the heating unit 121 and a physical external force from the pushing member 115. Also, the strength of the coating 52 is such that the coating 52 does not break if subjected only to a physical external force from the pushing member 115. Moreover, the strength of the coating 52 is such that the coating 52 does not break if, for example, pressure is applied to the region in which the capsule 50 is disposed by sandwiching the stick 1 between the thumb and the index finger of the user and pressing with the thumb and the index finger. In other words, the strength of the coating 52 is such that the coating 52 does not break when subjected to heat due to a person's body temperature and a physical external force exerted by the person.

[0081] The composition of the coating 52 is not particularly restricted, provided that the coating 52 does not break when subjected to either one of heat and a physical external force, and breaks when subjected to both of heat and a physical external force.

[0082] Examples of materials for the coating 52 include starch, dextrin, polysaccharides, agar, gellan gum, gelatin, polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene-acrylonitrile copolymer, styrene-butadiene-acrylonitrile copolymer, polyethylene, polypropylene, cellulose acetate, polyethylene terephthalate, polyamide, ethylene-acrylic acid plastic, ethylene-vinyl acetate plastic, ethylene-vinyl alcohol plastic, lipophilic materials, various natural gelling agents, etc. The coating 52 may also include fragrance components, plasticizers, colorants, etc.

[0083] Lipophilic materials include, for example, fats and oils, fatty acids, sugar fatty acid esters, hydrocarbons, aromatic hydrocarbons, chain ethers, higher fatty acid esters, higher alcohols, and hydrogenated products thereof. Fats and oils include, for example, 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, etc. Examples of sugar fatty acid esters include sucrose fatty acid esters, etc. Examples of hydrocarbons include terpenes, paraffins, beeswax, etc. Examples of hydrogenated products include hydrogenated products of fats and oils such as margarine, shortening, etc.

[0084] The composition of the coating 52 may have any one of the abovementioned materials as the main component, or may be any combination thereof.

[0085] The coating 52 of the capsule 50 breaks partially or fully when the capsule 50 is both heated to at least 100°C and subjected to a physical external force.

[0086] In the present embodiment, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released changes when heat is applied by the heating unit 121. Specifically, the breaking strength of the coating 52 of the capsule 50 for breakage to the extent that the contents 51 are released is reduced when heat is applied by the heating unit 121.

[0087] In other words, in the present embodiment, the strength of the coating 52 changes when heat is applied by the heating unit 121. Specifically, the coating 52 becomes brittle when subjected to heat by the heating unit 121.

[0088] Here, the breaking strength is the degree to which the capsule 50 does not break to the extent that the contents are released.

[0089] For example, the maximum value of stress immediately before the capsule 50 breaks may be defined as the breaking strength. The maximum stress immediately before the capsule 50 breaks can be measured using a rheometer such as the CR-3000EX-S manufactured by Sun Scientific Co., Ltd., which uses a contact for compressive strength testing. As the contact continuously descends, the capsule 50 begins to distort, generating stress on the contact.

[0090] Furthermore, for example, the temperature applied to the capsule 50 immediately before the capsule 50 breaks may be used as the breaking strength, and a value relating to the hydrophilicity or hydrophobicity of the capsule 50 coating may equally be used as the breaking strength. In addition, for example, the breaking strength may be determined on the basis of at least two of the above-mentioned matters.

[0091] For example, the coating 52 does not break if a physical external force from the pushing member 115 is applied to the capsule 50 before heat from the heating unit 121 is applied, but the coating 52 breaks if a physical external force from the pushing member 115 is applied to the capsule 50 after heat from the heating unit 121 is applied.

[0092] In addition, for example, if a physical external force from the pushing member 115 is applied to the capsule 50 before heat from the heating unit 121 is applied, the coating 52 does not break, but if heat from the heating unit 121 and a physical external force from the pushing member 115 are applied to the capsule 50 simultaneously, the coating 52 breaks.

[0093] The amount of contents 51 released when the coating 52 breaks varies on the basis of the external physical force applied to the capsule 50.

[0094] If a physical external force sufficient to break a portion of the coating 52 is applied a plurality of times to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the amount of the contents 51 still held by the coating 52 is reduced, and more of the contents 51 is released, compared to a case in which a physical external force is applied only once. Furthermore, if a gradually increasing physical external force is applied to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the contents 51 are released in such a way as to bleed out from the coating 52, making it possible to adjust the concentration of the flavor and taste provided by the capsule 50.

[0095] Furthermore, if a physical external force sufficient to break the entire coating 52 is applied at once to the capsule 50 after heat has been applied by the heating unit 121 or while heat is being applied, the contents 51 are released forcefully from the coating 52, making it possible to increase the concentration of the flavor and taste imparted by the capsule 50.

[0096] Also, in the present embodiment, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may change due to the application of a physical external force from the pushing member 115. In particular, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of a physical external force from the pushing member 115.

[0097] For example, if heat from the heating unit 121 is applied to the capsule 50 before a physical external force from the pushing member 115 is applied, the coating 52 does not melt to the extent that the capsule is partially or fully broken, but if heat from the heating unit 121 is applied to the capsule 50 after a physical external force from the pushing member 115 is applied, the coating 52 melts and breaks.

[0098] In addition, for example, if heat from the heating unit 121 is applied to the capsule 50 before a physical external force from the pushing member 115 is applied, the coating 52 does not melt, but if heat from the heating unit 121 and a physical external force from the pushing member 115 are simultaneously applied to the capsule 50, the coating 52 melts and breaks.

[0099] In addition, the amount of contents 51 released when the coating 52 breaks may vary on the basis of the temperature of the heat applied to the capsule 50.

[0100] Additionally, in the present embodiment, the state of the contents 51 of the capsule 50 may change. Specifically, the contents 51 may be solid at room temperature, but may be changed into a liquid by the heat from the heating unit 121.

[0101] For example, the configuration may be such that the coating 52 does not break if a physical external force from the pushing member 115 is applied to the capsule 50 while the contents 51 are in a solid state, but the coating 52 breaks if a physical external force from the pushing member 115 is applied when the contents 51 have reached a liquid state due to heat from the heating unit 121. In other words, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced as a result of liquefaction of the contents 51 of the capsule 50 due to heat from the heating unit 121.

[0102] The shape of the capsule 50 is not particularly restricted, and may be spherical, cylindrical, truncated conical, or the like. A plurality of capsules 50 may also be arranged.

[0103] The capsule 50 is preferably an elastic body that deforms elastically when subjected to a physical external force, and returns to its original shape and does not generate stress when no longer subjected to the physical external force. The capsule 50 may also be a body that maintains a deformed shape obtained when subjected to a physical external force, and generates stress even when no longer subjected to the physical external force.

[0104] The method for producing the capsule 50 is not particularly limited, but it is preferable to use a dropping method capable of producing capsules with a seamless coating 52.

[0105] As explained above, the stick 1 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 210 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 10 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115. It should be noted that the stick 1 need not include the cooling portion 20 shown in fig. 1, from the viewpoint of making the size more compact in the centerline direction.

[0106] The stick 1 is inserted into the holding portion 140 of the flavor inhaler 100. After the temperature of the substrate 11 heated by means of the heating unit 121 has reached a predetermined temperature, an aerosol is generated when the user inhales. When the user inhales, vapor and aerosol are cooled in the cooling portion 20.

[0107] The heated portion 10 includes the substrate portion 11, which is filled with an aerosol source, and the solid member 13 in which the capsule 50 is disposed.

[0108] Here, we will assume a case in which the heating unit 121 of the flavor inhaler 100 comes into contact with the region in which the substrate portion 11 is disposed but does not come into contact with the region in which the solid member 13 is disposed. The capsule 50 is subjected to heat from the heating unit 121. Specifically, heat within the substrate portion 11 that has been heated by the heating unit 121 propagates to the solid member 13, and the heat from the heating unit is applied to the capsule 50.

[0109] The capsule 50 is also subjected to a physical external force from the pushing member 115. Specifically, the region of the stick 1 in which the solid member 13 is located is pushed by the pushing member 115, thereby subjecting the capsule 50 to a physical external force from the pushing member 115.

[0110] The application of both heat from the heating unit 121 and a physical external force from the pushing member 115 to the capsule 50 causes the coating 52 to break partially or fully, thereby releasing the contents 51. As a result, a new flavor and taste can be imparted to the stick 1 by the capsule 50 disposed in the heated region.

[0111] Furthermore, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of heat from the heating unit 121.

[0112] A new flavor can be imparted by the capsule 50, the breaking strength of which has been reduced by the heat from the heating unit 121.

[0113] For example, the configuration may be such that the capsule 50 does not break if a physical external force from the pushing member 115 is applied before heat from the heating unit 121 is applied, and breaks partially or fully if a physical external force from the pushing member 115 is applied after heat from the heating unit 121 has been applied.

[0114] Unintended breakage of the capsule 50 can be suppressed in comparison with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115. Furthermore, in comparison with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115, the user can inhale more of the flavor and taste components contained in the contents 51 together with the aerosol generated by heating the substrate portion 11. In addition, with a configuration in which the capsule 50 is broken solely by a physical external force from the pushing member 115, it is difficult to change the flavor of the aerosol while the user is inhaling. Arranging that the capsule 50 breaks when subjected to a physical external force from the pushing member 115 after having been subjected to heat from the heating unit 121 allows a new flavor to be imparted by the capsule 50 at the user's desired timing.

[0115] Furthermore, the amount of the contents 51 released by the capsule 50 may vary on the basis of the number of times a physical external force has been applied by the pushing member 115.

[0116] The user's desired concentration of the flavor and taste can be imparted on the basis of the number of times a physical external force from the pushing member 115 has been applied to the capsule 50.

[0117] Furthermore, the capsule 50 breaking strength for breakage to the extent that the contents 51 are released may be reduced by the application of a physical external force from the pushing member 115.

[0118] After the application of a physical external force, the capsule 50 can be broken by heat.

[0119] For example, the configuration may be such that the capsule 50 does not break if heat from the heating unit 121 is applied before a physical external force from the pushing member 115 is applied, and breaks partially or fully if heat from the heating unit 121 is applied after an external force from the pushing member 115 has been applied.

[0120] Specifically, the configuration may be such that the capsule 50 does not break when subjected solely to heat from the heating unit 121, but is broken partially or fully by heat from the heating unit 121 when subjected to an external force from the pushing member 115. After the application of a physical external force, the capsule 50 can be broken by heat.

[0121] In addition, the capsule 50 may break partially or fully when subjected simultaneously to heat from the heating unit 121 and a physical external force from the pushing member 115.

[0122] Heat can be used to break the capsule 50.

[0123] The capsule 50 may break partially or fully when subjected both to heat from the heating portion 121 heating the capsule 50 to 100°C or more, and to a physical external force by the pushing member 115.

[0124] Unintended breakage of the capsule 50 can be suppressed in comparison with a configuration in which the coating 52 breaks when heated to less than 100°C by heat from the heating unit 121.<Second Embodiment>

[0125] Fig. 5 is a diagram showing the longitudinal cross section of a stick 2 according to a second embodiment.

[0126] The stick 2 according to the second embodiment differs from the stick 1 according to the first embodiment in that a heated portion 210 corresponding to the heated portion 10 is different. The differences from the first embodiment will be described below. In the first embodiment and the second embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0127] The heated portion 210 differs from the heated portion 10 in that the capsule 50 is disposed within the substrate portion 211. The heated portion 210 comprises a substrate portion 211 containing an aerosol source, a rolling paper 212 corresponding to the rolling paper 12, and a solid member 213 that prevents the substrate portion 211 from falling out from the first side end face of the heated portion 210. The heated portion 210 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the filter portion 210 using the tipping paper 40. By way of example, the material constituting the solid member 213 may be identical to the material constituting the solid member 13.

[0128] The heated portion 210 is formed into a cylindrical shape by wrapping the substrate portion 211 and the solid member 213 with the rolling paper 212. Moreover, if the heated portion 210 consists of two or more members, it is preferable to wrap each of the two or more members with the rolling paper and then further wrap them together with another rolling paper.

[0129] The substrate portion 211 is filled with an aerosol source, and the capsule 50 is embedded therein.

[0130] By way of example, the aerosol source filling the substrate portion 211 may be identical to the aerosol source filling the substrate portion 11.

[0131] The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 211, for example. The position in the longitudinal cross section of the heated portion 210 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the substrate portion 211. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the substrate portion 211.

[0132] Furthermore, the capsule 50 may equally be embedded toward the solid member 213 in the transverse cross section of the substrate portion 211, for example. The position in the longitudinal cross section of the heated portion 210 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from at least the second side end face of the substrate portion 211. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the substrate portion 211 and the solid member 213.

[0133] In the case of the present embodiment, the pushing member 115 of the flavor inhaler 100 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 2 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to the substrate portion 211 of the stick 2 in which the capsule 50 is disposed. The position of the pushing member 115 is preferably a position in which, when moved into the internal space 141, a physical external force can be applied to the region of the substrate portion 211 in which the capsule 50 is disposed.

[0134] As explained above, the stick 2 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 210 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 10 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0135] According to the stick 2, similarly to the stick 1, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0136] Furthermore, the capsule 50 is disposed within the substrate portion 211.

[0137] When the capsule 50 is disposed within the solid member 213, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 211 heated by the heating unit 121, and the temperature within the solid member 213 is the same as the temperature within the substrate portion 211 or is lower than the temperature within the substrate portion 211. In the present embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to break the capsule 50.

[0138] The present disclosure is not limited to the above examples, and a plurality of capsules 50 may each be disposed in a different region. Specifically, a capsule 50 may be disposed within the substrate portion 211 and a capsule 50 may also be dispose within the solid member 213. By disposing each of a plurality of capsules 50 in a different region, it is possible to provide differences between the ways heat and physical external force are applied to the capsules 50. Providing differences between the ways heat and physical external force are applied to the capsules 50 allows the timings at which the plurality of capsules 50 are broken to be staggered. Furthermore, providing differences between the ways heat and physical external force are applied to the capsules 50 allows a plurality of capsules 50 having different breaking strengths to be broken simultaneously.

[0139] It should be noted that the flavor inhaler 100 may be provided with a plurality of heating units 121 and a plurality of pushing members 115, and heat and physical external force may be applied separately to each of the plurality of capsules 50 disposed in the different regions.<Third Embodiment>

[0140] Fig. 6 is a diagram showing the longitudinal cross section of a stick 3 according to a third embodiment.

[0141] The stick 3 according to the third embodiment differs from the stick 2 according to the second embodiment in that a heated portion 310 corresponding to the heated portion 210 is different. The differences from the second embodiment will be described below. In the second embodiment and the third embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0142] The heated portion 310 differs from the heated portion 210 by not including the solid member 213. Furthermore, the heated portion 310 includes a substrate portion 311 containing an aerosol source and a rolling paper 312 corresponding to the rolling paper 212. The filter portion 310 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the filter portion 310 using the tipping paper 40.

[0143] The heated portion 310 is formed in a cylindrical shape by wrapping the substrate portion 311 with rolling paper 312.

[0144] The substrate portion 311 is filled with an aerosol source and the capsule 50 is embedded therein. The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 311, for example.

[0145] By way of example, the aerosol source filling the substrate portion 311 may be identical to the aerosol source filling the substrate portion 11 according to the first embodiment, as is the case with the substrate portion 211.

[0146] The capsule 50 is embedded in the center of the transverse cross section of the substrate portion 311. The position in the longitudinal cross section of the heated portion 310 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the substrate portion 311. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the heated portion 310.

[0147] In the case of the present embodiment, in the flavor inhaler 100 (see fig. 4), the size and placement of the heating unit 121 for heating the stick 3 are modified appropriately to heat the entire substrate portion 311. Furthermore, the size and placement of the heat insulating portion 144 correspond to those of the heating unit 121.

[0148] In addition, the pushing member 115 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 3 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the substrate portion 311 in which the capsule 50 is disposed.

[0149] As explained above, the stick 3 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 310 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 310 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0150] According to the stick 3, similarly to the stick 2, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0151] Furthermore, the heated portion 310 does not include a solid member 213 (see fig. 5) and the capsule 50 is disposed within the substrate portion 311.

[0152] In a case in which the heated portion 310 includes the solid member 213, the size of the substrate portion 311 in the centerline direction is reduced, and the aerosol source content is lower than the aerosol source content for a case in which the heated portion 310 does not include a solid member 213. Also, the heat applied to the capsule 50 is the temperature within the substrate portion 311 heated by the heating unit 121. In the present embodiment, breaking of the capsule 50 can be facilitated while increasing the concentration of aerosol to be inhaled.<Fourth Embodiment>

[0153] Fig. 7 is a diagram showing the longitudinal cross section of a stick 4 according to a fourth embodiment.

[0154] The stick 4 according to the fourth embodiment differs from the stick 1 according to the first embodiment in that a heated portion 410 corresponding to the heated portion 10 is different. The differences from the first embodiment will be described below. In the first embodiment and the fourth embodiment, the same reference signs are used for the same components, and detailed descriptions thereof are omitted.

[0155] 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 includes a substrate portion 411 containing an aerosol source, a rolling paper 412 corresponding to the rolling paper 12, and the solid member 413, which prevents movement of the substrate portion 411 toward the cooling portion 20. The heated portion 410 is connected (coupled) to the cooling portion 20 by integrally wrapping the cooling portion 20 and the heated portion 310 using the tipping paper 40.

[0156] The substrate portion 410 is formed in a cylindrical shape by wrapping the substrate portion 411 with the rolling paper 412.

[0157] The substrate portion 411 is disposed on the first side of the heated portion 410. Specifically, the first side end face of the substrate portion 411 is disposed so as to become the first side end face of the stick 4. By way of example, the aerosol source filling the substrate portion 411 may be identical to the aerosol source filling the substrate portion 11.

[0158] The solid member 413 is a member that prevents movement of the substrate portion 411 toward the cooling portion 20, and the capsule 50 is embedded therein. For example, the capsule 50 is embedded in the center of the transverse cross section of the solid member 413.

[0159] Also, by way of example, the material constituting the solid member 413 may be the material constituting the solid member 13. Furthermore, the material constituting the solid member 413 may contain a cooling element that undergoes a phase transition at the temperature within the solid member 413 to absorb heat while maintaining the temperature within the solid member 413 at a temperature at which the coating 52 can be broken and the components of the contents 51 can be volatilized. The type of the cooling element is not particularly limited, and it may, for example, be 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, cured oil, etc., or combinations thereof.

[0160] The capsule 50 is embedded in the center of the transverse cross section of the solid member 413. The position in the longitudinal cross section of the heated portion 410 in which the capsule 50 is embedded is preferably a position whereby the contents 51 do not leak from the first side end face or the second side end face of the solid member 413. In other words, the capsule 50 is preferably disposed in a position whereby diffusion of the contents 51 is kept within the solid member 413.

[0161] In the case of the present embodiment, in the flavor inhaler 100 (see fig. 4), the size and placement of the heating unit 121 for heating the stick 4 are modified appropriately to heat the entire substrate portion 411. Furthermore, the size and placement of the heat insulating portion 144 correspond to those of the heating unit 121.

[0162] In addition, the pushing member 115 (see fig. 3) is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to at least a portion of the region of the stick 4 in which the capsule 50 is disposed. Specifically, in the case of the present embodiment, the pushing member 115 is provided in a position in which, when moved into the internal space 141, a physical external force can be applied to the solid member 413 of the heated portion 410 in which the capsule 50 is disposed.

[0163] As explained above, the stick 4 is a stick for flavor inhalation that is heated when inserted into the flavor inhaler 100, and includes the heated portion 410 that is heated when inserted into the flavor inhaler 100, and the capsule 50 that is disposed within the heated portion 410 and that releases the contents 51 when broken. Furthermore, the capsule 50 does not break when subjected to either one of heat from the heating unit 121 and a physical external force from the pushing member 115, and breaks partially or fully when subjected to both of heat from the heating unit 121 and a physical external force from the pushing member 115.

[0164] According to the stick 4, similarly to the stick 1, it is possible to provide a stick for flavor inhalation capable of imparting a new flavor and taste by means of a capsule disposed in a region to which heat is applied.

[0165] Furthermore, the solid member 413 in which the capsule 50 is 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 capsule 50 is embedded is disposed on the second side relative to the substrate portion 411.

[0166] Here, we will assume a case in which the heating unit 121 of the flavor inhaler 100 comes into contact with the region in which the substrate portion 411 is disposed but does not come into contact with the region in which the solid member 413 is disposed. In a case in which the solid member 413 is disposed on the first side relative to the substrate portion 411, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 411 heated by the heating unit 121, while air passing through the solid member 413 is air flowing in from the first side end face of the stick 4. Meanwhile, in a case in which the solid member 413 is disposed on the second side relative to the substrate portion 411, the heat applied to the capsule 50 is heat that has propagated from the substrate portion 411 heated by the heating unit 121, and the air passing through the solid member 413 is air that has passed through the substrate portion 411. The temperature of the air that has passed through the substrate portion 411 is higher than the temperature of the air that flows in from the first side end face of the stick 4. In the present embodiment, the temperature of the heat applied to the capsule 50 can be increased, making it easier to break the capsule 50.

[0167] The present disclosure is not limited to the above examples, and a plurality of capsules 50 may each be disposed in a different region. Specifically, a capsule 50 may be disposed within the substrate portion 411 and a capsule 50 may also be dispose within the solid member 413. By disposing each of a plurality of capsules 50 in a different region, it is possible to provide differences between the ways heat and physical external force are applied to the capsules 50. Providing differences between the ways heat and physical external force are applied to the capsules 50 allows the timings at which the plurality of capsules 50 are broken to be staggered. Furthermore, providing differences between the ways heat and physical external force are applied to the capsules 50 allows a plurality of capsules 50 having different breaking strengths to be broken simultaneously.

[0168] It should be noted that the flavor inhaler 100 may be provided with a plurality of heating units 121 and a plurality of pushing members 115, and heat and physical external force may be applied separately to each of the plurality of capsules 50 disposed in the different regions.<Modified example 1>

[0169] The heat-not-burn type flavor inhaler 100 for heating the stick 1, 2, 3, 4 is not limited to the configuration discussed hereinabove, and may include a pushing member that is inserted into the inside of the stick 1, 2, 3, 4 to push the capsule 50.

[0170] Fig. 8 is a diagram showing an example of a flavor inhaler 200. Fig. 8 shows a cross-sectional view of the flavor inhaler 200, and the internal configuration of the flavor inhaler 200, which is normally not visible to a user, is omitted.

[0171] The flavor inhaler 200 according to the modified example 1 shown in fig. 8 differs from the flavor inhaler 100 shown in fig. 3 in that a pushing member 126 corresponding to the pushing member 115 is different. The differences from the flavor inhaler 100 shown in fig. 3 will be described below. The same reference signs are used for the same components in fig. 3 and fig. 9, and detailed descriptions thereof are omitted.

[0172] In the example shown in fig. 8, the flavor inhaler 200 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, a pushing member 126 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that closes an insertion opening into which the stick 1 is inserted. The flavor inhaler 200 also comprises a holding portion 140 that holds the stick 1 and an insertion opening 142 that provides communication between the internal space 141 and the outside.

[0173] As shown in fig. 8, the pushing member 126 protrudes into the internal space 141. The pushing member 126 applies a physical external force to at least a portion of the region of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 126 applies pressure to the capsule 50. The pushing member 126 may equally come into contact with the capsule 50.

[0174] It should be noted that the pushing member 126 is not limited to a form in which it always protrudes into the internal space 141, and may adopt a form allowing it to move into the internal space 141 when a button, which is not shown, is depressed.

[0175] When a physical external force has been applied by the pushing member 126, the capsule 50 may remain 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 pressing member 126 does not continuously apply a physical external force. This also has the aim of increasing the surface area of the capsule 50 that is exposed to heat.

[0176] Additionally, when subjected to a physical external force from the pushing member 126, the capsule 50 may move toward the outer peripheral surface of the stick 1, for example. This brings the capsule 50 closer to the heating unit 121 (see fig. 4), with the aim of increasing the temperature of the heat applied to the capsule 50.

[0177] The shape of the pushing member 126 may be modified as appropriate in accordance with the size of the flavor inhaler 100, but is preferably a shape that enables a physical external force to be applied to at least a portion of the region of the stick 1 in which the capsule 50 is disposed. The shape of the pushing member 126 is preferably a shape having a narrow tip, for example, from the viewpoint of ease of insertion into the interior of the stick 1.

[0178] Also, the region reached by the tip of the pushing member 126 is not limited to a region that coincides with the region in which the capsule 50 is disposed, and may be a region ahead of the region in which the capsule 50 is positioned, provided that pressure can be applied to the capsule 50.

[0179] Furthermore, in a case in which the capsule 50 is moved by the pushing member 126 toward the outer peripheral surface of the stick 1, the region reached by the tip of the pushing member 126 may be deeper than the region in which the capsule 50 is disposed. Moreover, the pushing member 126 may heat the stick 1.<Modified example 2>

[0180] In addition, the flavor inhaler 100 may include a pushing member that narrows the internal space 141 and pushes the stick 1, 2, 3, 4.

[0181] 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 the internal configuration of the flavor inhaler 300, which is normally not visible to a user, is omitted.

[0182] The flavor inhaler 300 shown in fig. 9 differs from the flavor inhaler 100 shown in fig. 3 in that a pushing member 127 corresponding to the pushing member 115 is different. The differences from the flavor inhaler 100 shown in fig. 3 will be described below. The same reference signs are used for the same components in fig. 3 and fig. 9, and detailed descriptions thereof are omitted.

[0183] In the example shown in fig. 9, the flavor inhaler 300 according to the modified example 2 comprises a front cover 110 that buffers heat released from the interior of the device to the exterior, the pushing member 127 that pushes the stick 1, a main body housing 120 to and from which the front cover 110 can be attached and detached, and a shutter 150 that closes an insertion opening into 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 provides communication between the internal space 141 and the outside.

[0184] As shown in fig. 9, the pushing member 127 narrows the internal space 141. The pushing member 127 applies a physical external force to the heated portion 10 of the stick 1 in which the capsule 50 is disposed. Specifically, the pushing member 127 applies pressure to the heated portion 10 in which the capsule 50 is disposed.

[0185] It should be noted that the pushing member 127 preferably moves into the internal space 141, thereby narrowing the internal space 141, when the stick 1 is held in the holding portion 140. Furthermore, the pushing member 127 may have a form that allows it to move into the internal space 141 when a button, which is not shown, is depressed by the user.

[0186] When a physical external force has been applied by the pushing member 127, the capsule 50 may remain deformed, for example from a spherical shape to an elliptical shape, as shown in fig. 9. This has the aim of increasing the surface area of the capsule 50 that is exposed to heat.

[0187] The shape of the pushing member 127 may be modified as appropriate in accordance with the size of the flavor inhaler 100, but is preferably a shape that allows the internal space 141 to be narrowed from the insertion opening 142 toward the region of the stick 1 in which the capsule 50 is disposed.

[0188] The pushing member 127 may be disposed on a portion of the outer periphery of the stick 1 or may be disposed so as to cover the outer periphery of the stick 1. Moreover, the pushing member 127 may heat the stick 1.<Summary>
