[0004] In a non-combustion heating type flavor inhalation stick that is heated by being inserted into a flavor inhaler, a capsule may be located in the area where heat is applied. With the flavor inhalation stick inserted into the flavor inhaler, it may be desired to destroy the capsule with heat and release the contents from the capsule to impart a new flavor flavor. However, it is difficult to destroy the capsule with heat from outside the flavor inhalation stick. The object of the present disclosure is to make it easier to destroy the capsule compared to a configuration in which the flavor inhalation stick is heated from the outside.

[0005] One aspect of the present disclosure provides a non-combustion-heating type flavor inhalation stick that is heated when inserted into a flavor inhaler. The flavor inhalation stick includes a capsule that is destroyed by heat to release at least a flavor component, and a storage unit that has a heating element for heating the capsule and stores the capsule. The heating element may be sheet-shaped. The heating element may be a porous body, or a porous sheet may be attached to the surface of the heating element. A plurality of heating elements may be dispersedly disposed in the storage unit. The capsule may be disposed so as to be in contact with the heating element. The capsule may be bonded to the heating element or sandwiched between the heating elements. A solid element may be disposed upstream of the storage unit. The storage unit may be filled with a flavor source that generates an aerosol when heated. The storage unit may include a substrate that generates an aerosol when heated, and the storage unit may be disposed adjacent to the substrate. The heating element may generate heat by induction heating. Furthermore, one aspect of the present disclosure provides a flavor inhalation system including the flavor inhalation stick and a flavor inhaler that heats the heating member of the flavor inhalation stick.

[0006] According to the present disclosure, the destruction of the capsule can be assisted by a flavor inhalation stick.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings, in which the same parts are designated by the same reference numerals.

[0009] First Embodiment Fig. 1 is a longitudinal cross-sectional view of a flavor inhalation stick 1 according to a first embodiment. The flavor inhalation stick (hereinafter sometimes referred to as a "stick") 1 according to the first embodiment includes a capsule 50, a heating member 70, and a storage section 13. The stick 1 also includes a cooling section 20 and a filter section 30. In the example of Fig. 1, the storage section 13 is included in the heated section 10, which may be heated by the heating member 70 induction-heated by a heating section 121 (see Fig. 2) of a flavor inhaler 100 (described later). The capsule 50 and the heating member 70 are disposed within the storage section 13 of the heated section 10. The stick 1 also includes tipping paper 40 connecting the heated section 10, the cooling member 20, and the filter section 30. The tipping paper 40 has a communication passage 60 formed therein, which connects the outside and the inside of the stick 1. Hereinafter, the direction of the center line CL of the heated section 10 may be referred to as the "center line direction." The stick 1 has a heated portion 10, a cooling portion 20, and a filter portion 30 arranged in this order along the center line, and is wrapped with tipping paper 40 to unite these together.

[0010] In this specification, one end side in the center line direction (the left side in FIG. 1 ) may be referred to as the first side, and the other end side in the center line direction (the right side in FIG. 1 ) may be referred to as the second side. The first side is the end side that is inserted into the flavor inhaler 100. The second side is the end side opposite the first side that the user holds in their mouth for inhalation. In addition, a cross section along the center line direction is referred to as a "longitudinal cross section," and a cross section cut along a plane perpendicular to the center line direction is defined as a "transverse cross section."

[0011] (Flavor inhalation system) FIG. 2 is a schematic diagram showing an example of the internal configuration of the flavor inhaler 100. The flavor inhalation system according to this embodiment includes the stick 1 according to the first embodiment and a non-combustion heating flavor inhaler 100 that heats the heated portion 10 of the stick 1 from the inside. The stick 1 according to the first embodiment is inserted into the non-combustion heating flavor inhaler 100 for use. As shown in FIG. 2, the main body 130 of the flavor inhaler 100 includes a heating unit 121 that heats the heating member 70 of the stick 1. The main body 130 also includes a power supply unit 131 that stores power and supplies power to each component of the main body 130, a sensor unit 132 that detects various information related to the main body 130, and a notification unit 133 that notifies the user of the information. The main body 130 also includes a memory unit 134 that stores various information for the operation of the main body 130, a communication unit 135 that transmits and receives information between the main body 130 and other devices, and a control unit 136 that controls overall operation within the main body 130. In the flavor inhaler 100, the user inhales a stick 1 inserted through the insertion opening 142 of the holding part 140 while the stick 1 is held in the space 141. Although not shown, the main body 130 of the flavor inhaler 100 may have an air flow path that penetrates from the bottom surface, which is the innermost part of the holding part 140, to the outer surface. The shape of this air flow path is not particularly limited, and may penetrate from the bottom surface of the holding part 140 to the outer surface in a straight line or in an L-shape, for example.

[0012] The power supply unit 131 supplies power for operating the heating unit 121. The power supply unit 131 supplies, for example, DC current. The control unit 136 controls the heating unit 121. The control unit 136 has, for example, a DC / AC inverter for supplying high-frequency AC current to the heating unit 121. When the flavor inhaler 100 is operated, high-frequency AC current passes through an induction coil that forms part of the heating unit 121. This causes the heating unit 121 to generate a fluctuating electromagnetic field. The frequency of the electromagnetic field is, for example, from 1 MHz to 30 MHz, preferably from 2 MHz to 10 MHz, and more preferably from 5 MHz to 7 MHz.

[0013] The heating unit 121 is an inductor that inductively heats the heating member 70. The heating unit 121 is arranged to cover the holding unit 140. Specifically, the heating unit 121 is arranged on the inner side surface of the holding unit 140, at a position corresponding to the heating member 70 when the stick 1 is inserted into the space 141 of the holding unit 140. The heating unit 121 generates a fluctuating electromagnetic field when current is supplied. The fluctuating electromagnetic field of the heating unit 121 may be generated, for example, when a user presses a switch (not shown), or may be generated automatically when the stick 1 is held in the space 141 of the holding unit 140. Eddy currents are generated within the heating member 70 located within the fluctuating electromagnetic field generated by the heating unit 121, resulting in heating of the heating member 70. Further heating is provided by magnetic hysteresis loss within the heating member 70. The heated heating member 70 heats the heated portion 10 of the stick 1 to a temperature sufficient to destroy the capsule 50. The flavor and aroma components released from the capsule 50 are inhaled by the user through the cooling unit 20 and the filter unit 30. The supply of current to the heating unit 121 may be continued, for example, while the sensor unit 132 detects that the user has inhaled, or may be stopped when the sensor unit 132 detects that the user has performed a predetermined operation.

[0014] (Stick 1) The stick 1 can be exemplified as a non-combustion heating type flavor inhalation article that releases flavor components when the capsule 50 is heated, for example. The cross section of the stick 1 is, for example, substantially circular, and the outer diameter and the size in the center line direction thereof can be appropriately changed according to the desired size.

[0015] The airflow resistance in the direction of the center line of each stick 1 is not particularly limited, but from the viewpoint of ease of smoking, it is usually 100 mmH ２ 0 or less, preferably 80 mmH ２ 0 or less, and more preferably 60 mmH ２ The airflow resistance in the center line direction of each stick 1 is usually 8 mmH ２ 0 or more, preferably 10 mmH ２ 0 or more, more preferably 12 mmH ２ The airflow resistance of the stick 1 is measured in accordance with the ISO standard method (ISO 6565) using, for example, a filter airflow resistance measuring device manufactured by Cerulean Co., Ltd. The airflow resistance of the stick 1 refers to the air pressure difference between the first side and the second side when air is flowed at a predetermined air flow rate (17.5 cc / sec) from the first side to the second side in a state where air does not pass through the side of the stick 1. The unit is generally mmH. ２ It is represented by O. It is known that the relationship between the size in the centerline direction and the airflow resistance of a non-combustion and heating type flavor inhalation article is proportional for normal sizes (e.g., 5 mm to 200 mm). Specifically, if the size in the centerline direction of a non-combustion and heating type flavor inhalation article is doubled, the airflow resistance will double.

[0016] (Cooling section 20) In the example shown in FIG. 1 , the cooling section 20 is disposed adjacent to the heated section 10 and the filter section 30, and is a section formed by wrapping a sheet 21 around it so that the cross section of a cylinder or the like is hollow (hollow). Because the cooling section 20 is a cylindrical member, it can cool the steam generated when the heated section 10 is heated, thereby generating an aerosol. The cooling section 20 is, for example, a paper tube formed by wrapping a sheet 21 made of paper around it.

[0017] The cross section of the cooling section 20 is substantially circular, and its outer diameter can be changed as appropriate to match the size of the stick 1, but is preferably approximately the same as the outer diameter of the filter 31 described below. If the cross section is not circular, the outer diameter is assumed to be a circle having the same area as the cross section, and the outer diameter of that circle is applied. The size of the cooling section 20 in the center line direction can be changed as appropriate to match the size of the stick 1, but a size that can ensure a sufficient cooling effect while obtaining a good flavor and that can suppress losses due to adhesion of the generated vapor and aerosol to the sheet 21 is desirable.

[0018] The material of the sheet 21 is not particularly limited, and may be, for example, a material primarily composed of pulp, or may be a material primarily composed of any of polyethylene, polypropylene, polyvinyl chloride, polyethylene terephthalate, polylactic acid, cellulose acetate, and aluminum foil, or any combination thereof. The cooling section 20 is formed by rolling the sheet 21, but is not limited to this configuration as long as the cross section is hollow. The cooling section 20 may be formed, for example, from a pipe made of synthetic resin or the like that already has a hollow cross section.

[0019] ((Filter section 30)) The filter section 30 is located on the second side (downstream side) of the cooling section 20. The filter section 30 has a filter 31 through which the aerosol passes. The filter section 30 is connected (coupled) by integrally winding up the second side end of the cooling section 20 and the first side end of the filter section 30 using tipping paper 40, which will be described later. The filter section 30 may also have a wrapping paper 32 wound between the outer peripheral surface of the filter 31 and the tipping paper 40.

[0020] The cross section of the filter 31 is substantially circular, and the diameter and perimeter of the circle can be changed as appropriate to match the size of the stick 1. If the cross section is not circular, the diameter is assumed to be that of a circle having the same area as the cross section, and the diameter of that circle is applied. In the example shown in FIG. 1 , the filter unit 30 has a plain filter consisting of a single filter 31, but this is not limited to this. The filter unit 30 may also have a multi-segment filter consisting of multiple filters, such as a dual filter consisting of two types of filters or a triple filter consisting of three types of filters. When the filter unit 30 has a multi-segment filter, it is preferable that the wrapper 32 is made up of each of the multiple filters, and then wrapped around another wrapper.

[0021] The airflow resistance per 12 mm of the size in the center line direction of the filter part 30 is not particularly limited, but is usually 40 mmH ２ O or more 300mmH ２ 0 or less, preferably 70 mmH ２ O or more 280mmH ２ 0 or less, and more preferably 90 mmH ２ O or more 260mmH ２ The airflow resistance of the filter unit 30 is measured in accordance with the ISO standard method (ISO 6565) using, for example, a filter airflow resistance measuring device manufactured by Cerulean Co., Ltd. The airflow resistance of the filter unit 30 refers to the air pressure difference between the first side and the second side when air is allowed to flow at a predetermined air flow rate (17.5 cc / min) from the first side to the second side in a state where air does not pass through the side surfaces of the filter unit 30. The unit is generally mmH. ２ It is represented by O. It is known that the relationship between the size of the filter unit 30 in the center line direction and the airflow resistance is proportional for normal sizes (e.g., 5 mm to 200 mm). Specifically, if the size of the filter unit 30 in the center line direction is doubled, the airflow resistance will double.

[0022] The filter 31 is not particularly limited as long as it contains a filter material and has the general functions of a filter. Examples of general filter functions include reducing unpleasant sensations such as irritation, and reducing nicotine and tar, but it is not necessary for the filter 31 to have all of these functions. Furthermore, since sticks 1 tend to produce fewer components and have a lower aerosol source filling rate than cigarette products, preventing the aerosol source from falling off while suppressing the filtering function and adjusting the airflow resistance to provide a moderate ease of inhalation are also important functions.

[0023] The filter material constituting the filter 31 is, for example, a columnar filler made of acetate, charcoal, cellulose fiber, nonwoven fabric, pulp paper, or the like. Alternatively, a paper filter filled with sheet-like pulp paper may be used. The filter 31 may also contain, as appropriate, known flavorings (e.g., menthol), adsorbents, granular activated carbon, flavor-retaining materials, and the like.

[0024] The wrapping paper 32 may be made primarily of pulp. Pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by blending non-wood pulp commonly used in tobacco wrapping papers, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in any combination of two or more types. The wrapping paper 32 may also contain fillers such as calcium carbonate.

[0025] The basis weight of the roll 32 is not particularly limited, but is usually 20 gsm to 100 gsm, preferably 22 gsm to 95 gsm, and more preferably 23 gsm to 90 gsm. The thickness of the roll 32 is not particularly limited, but is usually 20 μm to 140 μm, preferably 30 μm to 130 μm, and more preferably 30 μm to 120 μm.

[0026] The form of the wrapping paper 32 is not particularly limited, and may include one or more rows of seams containing adhesive. The adhesive may include a hot melt adhesive, and the hot melt adhesive may further include polyvinyl alcohol. The adhesive may also include a vinyl acetate adhesive. The wrapping paper 32 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. The wrapping paper 32 may be made of plastic, a polymer sheet, or the like. The wrapping paper 32 may also be a porous member having a plurality of pores formed therein.

[0027] (Tipping Paper 40) The tipping paper 40 is wound around the outer peripheral surfaces of the heated section 10, the cooling section 20, and the filter section 30. The shape of the tipping paper 40 is not particularly limited and may be, for example, square or rectangular. The configuration of the tipping paper 40 is not particularly limited and may be a common form, for example, tipping paper containing pulp as the main component. Pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing non-wood pulp commonly used in cigarette paper for tobacco products, such as flax pulp, hemp pulp, sisal pulp, or esparto. These pulps may be used alone or in combination of multiple types in any ratio. The tipping paper 40 may also contain a filler, such as calcium carbonate, in order to improve whiteness and opacity and increase the heating rate. The tipping paper 40 may also contain various auxiliary agents, such as a water resistance improver including a wet strength agent (WS agent) and a sizing agent.

[0028] The basis weight of the tipping paper 40 is not particularly limited, but is usually 32 gsm or more and 40 gsm or less, preferably 33 gsm or more and 39 gsm or less, and more preferably 34 gsm or more and 38 gsm or less. The air permeability of the tipping paper 40 is not particularly limited, but is usually 0 Coresta units or more and 30,000 Coresta units or less, and preferably more than 0 Coresta units and 10,000 Coresta units or less. "Air permeability" is a value measured in accordance with ISO 2965:2009, and is the rate at which an area of ​​1 cm2 is blown out per minute when the differential pressure between both sides of the paper is 1 kPa. ２ Flow rate of gas passing through (cm ３ 1 C.U. is expressed as cm under 1 kPa. ３ / (min cm ２ )

[0029] A coating agent may be added to at least one of the two surfaces, the front and back surfaces, of the tipping paper 40. While there are no particular limitations on the coating agent for the tipping paper 40, a coating agent that can form a film on the surface and reduce liquid permeability is preferred. A portion of the outer surface of the tipping paper 40 may also be coated with a known lip release material. The lip release material refers to a material configured to help the user easily separate the tipping paper 40 from their lips without causing substantial adhesion when they hold the filter portion 30 of the stick 1 in their mouth. The lip release material may include, for example, ethyl cellulose, methyl cellulose, etc. For example, the outer surface of the tipping paper 40 may be coated with the lip release material by applying an ethyl cellulose-based or methyl cellulose-based ink to the outer surface of the tipping paper.

[0030] ((Communicating passage 60)) The communicating passage 60 connects the outside and the inside of the stick 1. Therefore, the communicating passage 60 allows air from outside the stick 1 to flow into the inside during inhalation. Examples of the shape of the communicating passage 60 include a cylindrical shape, an elliptical cylindrical shape, a polygonal prism, a rounded polygonal prism, and a mortar shape. The communicating passage 60 is formed by a through-hole (also referred to in the technical field as a "ventilation filter (Vf)") formed in at least the region of the tipping paper 40 where the cooling section 20 is arranged. In the example shown in FIG. 1 , a plurality of communicating passages 60 are formed in the cooling section 20, and are formed concentrically in the circumferential direction of the cooling section 20. Note that the communicating passages 60 are not limited to being formed around the entire circumference of the cooling section 20, but may be formed in part of the circumferential direction of the cooling section 20. Furthermore, if a plurality of concentric communicating passages 60 are considered to be one communicating passage group, there may be one communicating passage group, or there may be two or more communicating passage groups.

[0031] The presence of the communication passage 60 that connects the outside and inside of the stick 1 allows air to flow from the outside into the inside of the cooling section 20 when the user inhales on the stick 1. This makes it possible to adjust the concentration of the inhaled flavor components and aerosol. It also promotes the cooling of the vapor and air that flow in from the heated section 10. Furthermore, when the heated section 10 is heated, the vapor generated using the aerosol as a condensation nucleus comes into contact with the air from the outside, lowering its temperature and liquefying, thereby promoting the generation of the aerosol.

[0032] The position of the communication passage 60 in the center line direction is preferably a position where air can flow in from outside the stick 1, for example, a position within the area protruding from the insertion opening 142 when the stick 1 is held in the holding portion 140 of the flavor inhaler 100. Furthermore, from the viewpoint of improving the delivery efficiency of aerosols and the like generated by heating, the position of the communication passage 60 in the center line direction is preferably 4 mm or more away from the boundary between the cooling portion 20 and the filter portion 30 toward the first side (upstream side). The position of the communication passage 60 in the center line direction is more preferably 4.5 mm or more away, even more preferably 5 mm or more away, and even more preferably 5.5 mm or more away. Furthermore, from the viewpoint of ensuring the cooling function of the cooling portion 20, the position of the communication passage 60 in the center line direction is preferably within 15 mm toward the first side (upstream side) from the boundary between the cooling portion 20 and the filter portion 30. The position of the communication passage 60 in the center line direction is more preferably within 10 mm, even more preferably within 7 mm. Furthermore, from the viewpoint of improving the delivery efficiency of aerosols and the like generated by heating, the position of the communicating passage 60 in the center line direction is preferably at least 24 mm away from the end face of the second side of the stick 1 toward the first side (upstream side). The position of the communicating passage 60 in the center line direction is more preferably at least 24.5 mm away, even more preferably at least 25 mm away, and even more preferably at least 25.5 mm away. From the viewpoint of ensuring the cooling function of the cooling unit 20, the position of the communicating passage 60 in the center line direction is preferably within 35 mm toward the first side (upstream side) from the end face of the second side of the stick 1. The position of the communicating passage 60 in the center line direction is more preferably within 30 mm, even more preferably within 27 mm. Furthermore, when the size of the cooling unit 20 in the center line direction is 20 mm or more, from the viewpoint of improving the delivery efficiency of aerosols and the like generated by heating, the position is preferably within 16 mm toward the second side (downstream side) from the boundary between the heated portion 10 in which the heating member 70 is housed and the cooling unit 20. The position of the communication passage 60 in the center line direction is more preferably within 15.5 mm, even more preferably within 15 mm, and even more preferably within 14.5 mm.Furthermore, from the viewpoint of ensuring the cooling function of the cooling section 20, the position of the communication passage 60 in the center line direction is preferably 5 mm or more away in the direction of the second side (downstream side) from the boundary between the heated section 10 and the cooling section 20. The position of the communication passage 60 in the center line direction is more preferably 10 mm or more away, and even more preferably 13 mm or more away.

[0033] The communicating passages 60 are arranged so that the air inflow rate through the communicating passages 60 is 10% by volume or more and 90% by volume or less when an automatic smoking machine inhales a cigarette at 17.5 ml / sec. This "air inflow rate" refers to the volumetric rate of air inflowing through the communicating passages 60 when the volumetric rate of air inhaled from the second end of the stick 1 is taken as 100% by volume. The air inflow rate is preferably 50% by volume or more and 80% by volume or less, and more preferably 55% by volume or more and 75% by volume or less. These air inflow rates can be achieved, for example, by selecting the number of communicating passages 60 per communicating passage group from the range of 5 to 50, selecting the diameter of the openings of the communicating passages 60 from the range of 0.1 mm to 0.5 mm, and combining these selections. The air inflow rate can be measured using a roll quality measuring device (e.g., a SODIMAX D74 / SODIM manufactured by SAS) in accordance with ISO 9512.

[0034] The communicating path 60 is composed of a through hole formed in the tipping paper 40 and a through hole formed in the sheet 21 of the cooling unit 20. The through hole is formed, for example, by a laser. The through hole in the tipping paper 40 is preferably formed directly above the through hole formed in the sheet 21. When producing such a stick 1, tipping paper 40 with a through hole overlapping the through hole in the sheet 21 may be prepared and wrapped around the stick 1. However, from the viewpoint of ease of production, it is preferable to produce a stick 1 without a communicating path 60 and then drill holes that penetrate both the sheet 21 and the tipping paper 40 at the same time. Note that the intensity of the laser light irradiated after wrapping the tipping paper 40 around the sheet 21 may be such that it penetrates the tipping paper 40 but not the sheet 21. Even in such a case, if the sheet 21 has a plurality of pores and is breathable, the through holes in the tipping paper 40 and the pores in the sheet 21 form a communicating path 60 that connects the outside of the stick 1 with the inside of the cooling unit 20.

[0035] (Capsule 50) The capsule 50 includes a content 51 containing a flavor component and a coating 52 that holds the content 51. The content 51 may include, for example, an aerosol source that generates an aerosol when heated, or may include only the aerosol source without the flavor component. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3-butanediol, and the like, or a combination thereof. The capsule 50 is disposed inside the container 13. The position of the capsule 50 in the vertical cross section of the container 13 is preferably such that the content 51 does not leak from the first end face and the second end face of the container 13 when the capsule 50 is broken. In other words, the capsule 50 is preferably disposed in a position where the diffusion of the content 51 is contained within the container 13.

[0036] The shape of the capsule 50 is not particularly limited and may be, for example, spherical, cylindrical, or truncated conical. A plurality of capsules 50 may also be arranged. The size of the capsule 50 is not particularly limited and is typically 2 mm or more and 5 mm or less in diameter. It is preferable that the size of the capsule 50 is such that it contains a sufficient amount of the contents 51, while the airflow resistance of the stick 1 due to the capsule 50 does not increase significantly compared to a stick without the capsule 50. This makes it possible to achieve appropriate airflow resistance even in a stick 1 in which the capsule 50 is not broken.

[0037] The state of the contents 51 is not particularly limited and may be liquid, gel, solid, or the like. The state of the contents 51 may also change. For example, the contents 51 may be solid at room temperature but may be transformed into a liquid by heat from the heating element 70. When the contents 51 are liquid or gel, the boiling point of the contents 51 is preferably higher than the temperature at which the coating 52 melts. When the released contents 51 are liquid or gel, the viscosity of the contents 51 is preferably such that the contents 51 penetrate the storage section 13 without leaking from the first end face and the second end face of the storage section 13. The amount of liquid in the contents 51 is preferably such that the contents 51 sufficiently penetrate the storage section 13 and do not reach the first end face of the stick 1 and spill into the flavor inhaler 100. This prevents the contents 51 from seeping out of the stick 1 while imparting a new flavor and taste when the contents 51 spread within the storage section 13.

[0038] The flavor component contained in the contents 51 is, for example, a flavor component. Specifically, the contents 51 is, for example, a flavor component that volatilizes when heated. The flavor component is not particularly limited, and examples include powdered flavors and oil-based flavors. Main powdered flavors include powdered chamomile, fenugreek, menthol, peppermint, cinnamon, herbs, etc. Main oil-based flavors include lavender, cinnamon, cardamom, celery, clove, cascarilla, nutmeg, sandalwood, bergamot, geranium, honey essence, rose oil, vanilla, lemon, orange, peppermint, cinnamon bark, caraway, cognac, jasmine, chamomile, menthol, cassia, ylang-ylang, sage, spearmint, fennel, pimento, ginger, anise, coriander, coffee, tobacco, etc. The flavor component may be used alone or in combination of two or more. When a powdered flavoring is used, its particle size is preferably 500 μm or less. The flavor and aroma components contained in the contents 51 may include not only flavoring components but also, for example, taste components. Examples of taste components include citric acid, tartaric acid, sodium glutamate, neotame, thaumatin, stevia, sorbitol, xylitol, erythritol, aspartame, rutin, hesperidin, oxalic acid, tannic acid, catechin, naringin, quinine, quinic acid, limonin, caffeine, capsaicin, vitamins, amino acids, polyphenols, alginic acid, flavonoids, and lecithin.

[0039] The contents 51 may contain a foaming component that foams when heated. The foaming component is a substance that generates gas when heated by the heating element 70, and examples of such a foaming component include hydrocarbons, sodium bicarbonate, and carbonated water. The contents 51 may also contain a coloring agent, such as a synthetic coloring agent or a natural coloring agent. Food additives such as Red No. 3,106, beta-carotene, copper chlorophyllin, gardenia blue pigment, and Yellow No. 4 are preferred coloring agents. The contents 51 may also contain a solvent that dissolves flavor and aroma components. Examples of the solvent include medium-chain fatty acid triglycerides, glycerin, propylene glycol, water, and ethanol.

[0040] The coating 52 enclosing the contents 51 is destroyed when heat is applied from the heating element 70. Here, "destroyed" includes a state in which the coating 52 is cracked to the extent that the contents 51 are released all at once, or a state in which the coating 52 is melted. "Destroyed" also includes a state in which the coating 52 is cracked to the extent that the contents 51 are released gradually, a state in which a hole is formed in the coating 52, or a state in which flavor and aroma components volatilized from the contents 51 permeate the coating 52. The strength of the coating 52 is such that it is destroyed when heat is applied from the heating element 70. Furthermore, the strength of the coating 52 is such that it is not destroyed when heat from a human body temperature is applied, for example.

[0041] The composition of the coating 52 is not particularly limited as long as it is destroyed when heated by the heating member 70. 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. Examples of lipophilic materials include oils and fats, fatty acids, sugar fatty acid esters, hydrocarbons, aromatic hydrocarbons, linear ethers, higher fatty acid esters, higher alcohols, and hydrogenated products thereof. Examples of fats and oils include glycerin fatty acid esters of safflower oil, linseed oil, sesame oil, olive oil, soybean oil, mustard oil, rapeseed oil, corn oil, castor oil, evening primrose oil, palm kernel oil, jojoba oil, cottonseed oil, coconut oil, peanut oil, and cocoa oil. Examples of sugar fatty acid esters include sucrose fatty acid esters. Examples of hydrocarbons include terpenes, paraffin, and beeswax. Examples of hydrogenated fats and oils include margarine and shortening. The coating 52 may also contain a flavoring component, a foaming component, a plasticizer, a coloring agent, and the like. The composition of the coating 52 may be primarily composed of any of the above materials, or any combination thereof.

[0042] (Heated portion 10) Fig. 3 is a diagram showing an example of a cross section of the flavor inhalation stick 1 according to the first embodiment, taken along line III-III in Fig. 1. The heated portion 10 has a wrapping paper 12 that covers the outer periphery of the heated portion 10, and a storage portion 13 that stores the capsule 50. The heated portion 10 also has disposed therein the capsule 50 and a heating member 70 that heats the capsule 50. The heated portion 10 is formed, for example, in a cylindrical shape. The heated portion 10 is connected (coupled) to the cooling portion 20 by winding the cooling portion 20 and the heated portion 10 together using tipping paper 40. Note that the heated portion 10 may not have the wrapping paper 12, and may be connected (coupled) to the cooling portion 20 by winding the cooling portion 20 and the storage portion 13 together.

[0043] The storage section 13 is a section that has the heating member 70 and stores the capsule 50. At least a portion of the storage section 13 is stored in the space 141 when the stick 1 is held in the holding section 140. Specifically, at least a portion of the storage section 13 is stored in the space 141 so that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 1 is held in the holding section 140. The cross section of the storage section 13 is substantially circular, and the diameter of the circle and the perimeter of the cross section can be changed appropriately according to the size of the stick 1. Note that if the cross section is not circular, the above diameter is assumed to be a circle having the same area as the area of ​​the cross section, and the diameter of that circle is applied.

[0044] The storage section 13 may be a hollow (hollow) cylindrical member or a solid columnar member. The material constituting the storage section 13 is not particularly limited, but is preferably a material through which the contents 51 of the capsule 50 can permeate. Examples of materials constituting the storage section 13 include cellulose acetate fiber, nonwoven fabric, pulp paper, a processed product obtained by molding a raw material containing flavor components into a sheet (hereinafter referred to as a "flavor sheet"), a processed product obtained by molding a resin into a sheet (hereinafter referred to as a "resin sheet"), and plastic molded into a desired shape. When two or more components are filled in the storage section 13, the multiple components may differ from one another in composition, physical properties, size, shape, etc.

[0045] Here, a case where the storage section 13 is composed of a sheet-like member (hereinafter referred to as a "sheet member") such as pulp paper, a flavor sheet, or a resin sheet will be described. When the storage section 13 is composed of a single sheet member, for example, a sheet member having one side approximately the same size as the centerline of the storage section 13 is filled in a state where it is folded back multiple times horizontally relative to the centerline of the storage section 13 (a so-called gathered sheet). Another example is a sheet member having one side approximately the same size as the centerline of the storage section 13, wound in a direction perpendicular to the centerline of the storage section 13. When the storage section 13 is composed of two or more sheet members, for example, a multiple sheet member having one side approximately the same size as the centerline of the storage section 13 is filled in a state where it is wound in a direction perpendicular to the centerline of the storage section 13 so as to be concentrically arranged. "Concentrically arranged" means that the centers of all the sheet members are arranged at approximately the same position. The sheet material constituting the storage section 13 may be in a cut state. Furthermore, the storage section 13 may be a so-called strand type in which a sheet material having a size approximately the same as the size of the storage section 13 in the center line direction is filled and cut approximately horizontally to the center line direction.

[0046] Furthermore, when the storage unit 13 is formed of a sheet member, the capsules 50 and the heating member 70 may be fixed to the sheet member. Specifically, the storage unit 13 may be formed by filling the sheet member to which the capsules 50 and the heating member 70 are fixed. By fixing the capsules 50 and the heating member 70, the arrangement of the capsules 50 and the heating member 70 in the storage unit 13 can be maintained. By filling the sheet member to which the capsules 50 and the heating member 70 are fixed, the arrangement of the capsules 50 and the heating member 70 in the storage unit 13 can be easily adjusted to a desired arrangement.

[0047] The storage section 13 may also be a location where aerosol is generated by heating, and may contain, for example, a flavor source. The flavor source contained in the storage section 13 may be tobacco-derived, such as a processed product obtained by molding tobacco shreds or tobacco raw materials into granules, sheets, or powder, or dried tobacco leaves (dried tobacco leaves). The flavor source may also include non-tobacco-derived sources made from plants other than tobacco (e.g., mint and herbs). The aerosol source may also contain a flavoring. The flavor source may also include dried tobacco leaves and a flavoring-containing material in which a flavoring is encapsulated in a polysaccharide gel. The type of flavoring is not particularly limited, and menthol is particularly preferred from the perspective of imparting a good flavor. The flavoring contained in the flavor source may be used alone or in combination of two or more types. When the flavor inhaler 100 is a medical inhaler, the flavor source may also include a medication to be inhaled by the patient. The components constituting the flavor source are not limited to solid materials, but may include, for example, polyhydric alcohols such as glycerin and propylene glycol, and liquid materials such as water. The form of the flavor source is not limited to solid or semi-solid, but may be, for example, a capsule containing a liquid material.

[0048] Furthermore, when the flavor source contained in the storage section 13 is derived from tobacco, the type of tobacco used is not particularly limited, and various known types can be used. Examples of tobacco types include flue-cured tobacco, burley tobacco, oriental tobacco, native tobacco, other Nicotiana tabacum varieties, Nicotiana rustica varieties, and mixtures thereof. Mixtures are used by appropriately blending various varieties to achieve the desired flavor. Furthermore, even when the flavor source is derived from tobacco, various extracts and / or their constituents from natural products may be included depending on the intended use. Examples of extracts and / or their constituents include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.

[0049] Furthermore, when the flavor source contained in the storage section 13 is tobacco shreds or a processed product obtained by forming tobacco raw materials into a sheet (hereinafter referred to as "tobacco sheet"), it can be appropriately manufactured by known methods such as papermaking, slurrying, rolling, etc. The tobacco sheet may also be made by grinding dried tobacco leaves to obtain tobacco grounds, homogenizing this using known means, and then processing it into a sheet. The tobacco sheet is an example of a sheet member. The number of tobacco sheets may be one, two, or more.

[0050] The cigarette paper 12 is not particularly limited in composition and may be of a general type, such as one primarily composed of pulp. Pulp may be made from wood pulp, such as softwood pulp or hardwood pulp, or may be made by blending non-wood pulp, such as flax pulp, hemp pulp, sisal pulp, or esparto, which are commonly used in cigarette papers 12 for tobacco products. Pulp types that can be used include chemical pulp produced by kraft cooking, acidic, neutral, or alkaline sulfite cooking, or soda cooking, ground pulp, chemi-ground pulp, and thermomechanical pulp. The cigarette paper 12 may also be made from, for example, a tobacco sheet, a flavor sheet, or a resin sheet. The cigarette paper 12 may contain a filler, such as calcium carbonate, in order to improve whiteness and opacity and increase the heating rate. The wrapping paper 12 may also contain various additives, and may have a coating agent added to at least one of its two surfaces, the front and back surfaces.

[0051] The lower limit of the basis weight of the cigarette paper 12 is, for example, usually 20 gsm or more, and preferably 25 gsm or more. On the other hand, the upper limit of the basis weight of the cigarette paper 12 is, for example, usually 65 gsm or less, preferably 50 gsm or less, and more preferably 45 gsm or less. The lower limit of the thickness of the cigarette paper 12 is not particularly limited, and from the viewpoints of rigidity, breathability, and ease of adjustment during papermaking, it is usually 10 μm or more, preferably 20 μm or more, and more preferably 30 μm or more. On the other hand, the upper limit of the thickness of the cigarette paper 12 is usually 100 μm or less, preferably 75 μm or less, and more preferably 50 μm or less.

[0052] The shape of the wrapping paper 12 wound around the outer peripheral surface of the storage section 13 can be, for example, a square or a rectangle. The size of the wrapping paper 12 can be determined depending on the size of the storage section 13. When the material constituting the storage section 13 is wrapped in the wrapping paper 12 into a cylindrical shape, for example, an end of the wrapping paper 12 and an end of the wrapping paper 12 on the opposite side in the circumferential direction are overlapped by about 2 mm and glued together to form a cylindrical paper tube, which is filled with the material constituting the storage section 13. Furthermore, when a cylindrical paper tube is formed in advance using the wrapping paper 12, the material constituting the storage section 13 may be filled into the paper tube formed by the wrapping paper 12, for example.

[0053] The heating member 70 is a member that heats the capsule 50. Specifically, the heating member 70 is a member that heats the capsule 50 by electromagnetic induction. The heating member 70 is heated by eddy currents generated within the heating member 70 by the fluctuating electromagnetic field generated by the heating unit 121. The heated heating member 70 heats the surrounding capsule 50 and destroys it. The material constituting the heating member 70 may be any material that converts electromagnetic energy into heat, such as metal or carbon. When the material constituting the heating member 70 is metal, examples of the material include aluminum, iron, iron alloy, stainless steel, nickel, nickel alloy, or a combination of two or more of these. The heating member 70 may have a layered structure, such as a three-layer structure in which two layers of stainless steel cover a nickel alloy (permalloy).

[0054] The heating member 70 extends within the storage portion 13 along the centerline (longitudinal) direction of the stick 1. The storage portion 13 may have one heating member 70 or two or more heating members 70. In the example shown in FIG. 3 , the storage portion 13 stores the capsules 50 with one heating member 70 positioned toward the center in the cross section. Specifically, the thin, plate-like heating member 70 extending in the centerline direction is positioned so that its cross section is flat (approximately linear) in the cross section of the storage portion 13. The capsules 50 are stored near the heating member 70. This allows the capsules 50 to be destroyed by the heat generated by the heating member 70 within the storage portion 13. Furthermore, from the viewpoint of improving the heating efficiency of the capsules 50, it is preferable that the heating member 70 be in contact with the capsules 50. In other words, it is preferable that the capsules 50 be positioned so that they are in contact with the heating member 70. Furthermore, it is preferable that the capsules 50 be adhesively attached to the heating member 70. The placement of the capsule 50 is not limited to being near the center of the cross section of the storage section 13, but may be near the outer periphery of the cross section of the storage section 13, specifically near the wrapping paper 12, as long as it can be heated by the heating member 70. When the heating member 70 inside the storage section 13 generates heat, heat is more easily transferred to the capsule 50, making it easier to destroy the capsule 50, compared to a configuration in which heat is applied to the capsule 50 from outside the storage section 13.

[0055] The length of the heating member 70 is not particularly limited in the cross section of the storage section 13, and may be shorter than or equal to the diameter of the storage section 13 as shown in FIG. 3 . The thickness of the heating member 70 is not particularly limited, but a thinner heating member is preferable from the viewpoint of suppressing an increase in airflow resistance due to the heating member 70. The shape of the heating member 70 is not limited to a rectangular shape, and at least one end of the heating member 70 in the center line direction may be sharp. The heating member 70 may have a protrusion protruding in its thickness direction or a recess recessed in its thickness direction. The cross-sectional shape of the heating member 70 may be polygonal, circular, or elliptical.

[0056] From the viewpoint of preventing the contents 51 from leaking to the outside of the stick 1, the heating member 70 is preferably a member that serves as a destination for the contents 51 released from the capsule 50. For example, the heating member 70 is a porous body having a plurality of pores through which the contents 51 can enter. Furthermore, for example, the heating member 70 may have different properties between a first layer 71 that does not contact the capsule 50 and a second layer 72 that contacts the capsule 50. Specifically, the heating member 70 may have a second layer 72 that contacts the capsule 50, the second layer 72 being formed by surface treatment such as attaching a sheet that has better water absorption than the first layer 71, which is the base material of the heating member 70. In other words, the surface of the heating member 70 may be surface-treated, such as by attaching a sheet with better water absorption. An example of a "sheet with better water absorption" is a porous sheet. Alternatively, for example, the heating member 70 may have a depression formed on its surface that can serve as a receptacle for the contents 51. The contents 51 released from the capsule 50 remain inside or on the heating member 70, thereby improving the heating efficiency of the contents 51 while preventing the contents 51 from leaking out of the stick 1. Furthermore, the evaporation of flavor and aroma components contained in the contents 51 can be promoted.

[0057] The heating member 70 is not limited to the example shown in FIG. 3 . Specifically, the heating member 70 does not have to be a single member, as shown in FIG. 3 , and its cross-sectional shape does not have to be flat. FIG. 4 is a diagram showing another example of a cross-section of the flavor inhalation stick 1 according to the first embodiment, taken along line III-III in FIG. 1 . In the example shown in FIG. 4 , the storage section 13 stores capsules 50 in a state in which multiple heating members 70 are arranged so that each has a curved cross-sectional shape. Specifically, two heating members 70 are arranged so that their cross-sectional shapes are S-shaped in the cross-section of the storage section 13, and the capsules 50 are stored sandwiched between the heating members 70. When the heating member 70 has a curved shape, it is preferable that the heating member 70 contact the wrapping paper 12 at two or more locations in the cross-section of the storage section 13, from the viewpoint of suppressing movement of the heating member 70 itself. Note that the capsule 50 may not only be sandwiched between the heating members 70, but also be adhered to at least one of the heating members 70. Furthermore, the placement of the capsule 50 is not limited to being near the center of the cross section of the storage section 13, but may be near the outer periphery of the cross section of the storage section 13, specifically near the wrapping paper 12.

[0058] By providing multiple heating members 70 within the storage unit 13, the heating efficiency of the capsule 50 within the storage unit 13 can be improved compared to a configuration having only one heating member 70. Furthermore, by sandwiching the capsule 50 between multiple heating members 70, the surface area of ​​the heating members 70 in contact with the capsule 50 can be increased, improving the heating efficiency of the capsule 50. Furthermore, by providing a curved cross-sectional shape for the heating members 70, the surface area of ​​the heating members 70 can be increased, improving the heating efficiency within the storage unit 13, compared to a configuration in which the cross-sectional shape of the heating members 70 is flat.

[0059] Fig. 5 is a diagram showing another example of a cross-section of the flavor inhalation stick 1 according to the first embodiment, taken along line III-III in Fig. 1 . In the example shown in Fig. 5 , the storage unit 13 stores the capsules 50 with one heating element 70 arranged so that it is curved at multiple locations. Specifically, the heating elements 70 are arranged so that their cross-sectional shape is Ω-shaped in the cross-section of the storage unit 13, and the capsules 50 are sandwiched between the heating elements 70. By having the Ω-shaped cross-section of the heating element 70, even with a single heating element 70, the surface area of ​​the heating element 70 can be increased to the same extent as when two heating elements 70 with S-shaped cross-sections are arranged, thereby improving the heating efficiency within the storage unit 13. Furthermore, when the capsules 50 are sandwiched between the heating elements 70, the adjustment of the relative positions of the heating elements 70, which is required when sandwiching the capsules 50 between multiple heating elements 70, is not required.

[0060] FIG. 6 is a diagram showing another example of a cross-section of the flavor inhalation stick 1 according to the first embodiment, taken along line III-III in FIG. 1 . In the example shown in FIG. 6 , the storage unit 13 stores the capsules 50 with multiple heating elements 70 arranged in a dispersed manner. Specifically, multiple heating elements 70 with circular cross-sections are arranged in the storage unit 13, and the capsules 50 are stored surrounded by the heating elements 70. The capsules 50 may be in contact with multiple heating elements 70. Furthermore, the heating elements 70 are not particularly limited, and their cross-sectional shapes may be elliptical, polygonal, or the like, or may be columnar or granular extending in the direction of the centerline. Distributing the multiple heating elements 70 in a dispersed manner allows the entire storage unit 13 to be efficiently heated. Furthermore, the heating efficiency of the capsules 50 can be improved. Distributing the heating elements 70 allows the storage unit 13 to be heated even when a portion of the storage unit 13 is not located within the fluctuating electromagnetic field of the heating unit 121.

[0061] As described above, the stick 1 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a capsule 50 that is broken by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a storage section 13 that stores the capsule 50. Note that, from the viewpoint of compact size in the center line direction, the stick 1 does not need to include a cooling section 20 that cools the vapor and aerosol when the user inhales.

[0062] Here, assume that the heating member 70 generates heat due to induction heating. A user inserts the stick 1, with the capsule 50 still intact, into the holding portion 140 of the flavor inhaler 100. The heating member 70 in the storage portion 13 is heated by eddy currents generated within the heating member 70 by the fluctuating electromagnetic field of the heating portion 121, and generates heat. As the heating member 70 generates heat, heat is applied to the capsule 50 from within the storage portion 13. As a result, the heat applied to the capsule 50 placed within the storage portion 13 is more likely to be high compared to a configuration in which heat is applied to the capsule 50 from the outside. The stick 1 can more easily destroy the capsule by heat compared to a configuration in which heat is applied from the outside of the stick 1.

[0063] For example, the heating member 70 may be in a sheet shape. This makes it easy to form the cross-sectional shape of the heating member 70 in the transverse cross section of the storage section 13 into a desired shape. In addition, it is easy to ensure the surface area of ​​the heating member 70. By ensuring the surface area of ​​the heating member 70, the heating efficiency of the capsules 50 by the heating member 70 can be improved. By making it easier for the heat from the heating member 70 to be applied to the capsules 50, it is possible to easily destroy the capsules by heat.

[0064] It is also preferable that the heating member 70 is made of a porous material, or that a porous sheet is attached to the surface of the heating member 70. This ensures a place for the content 51 released from the capsule 50 to go, and prevents the content 51 from leaking out of the stick 1.

[0065] It is also preferable that a plurality of heating members 70 are dispersedly disposed in the storage unit 13. This allows the entire storage unit 13 to be heated efficiently, making it easier to apply heat to the capsules 50. Furthermore, by dispersing the heating members 70, the storage unit 13 can be heated even when a part of the storage unit 13 is not located within the fluctuating electromagnetic field of the heating unit 121.

[0066] Furthermore, the capsule 50 is preferably disposed so as to be in contact with the heating member 70. By directly transmitting the heat of the heating member 70 to the capsule 50, the heating efficiency of the capsule 50 can be improved.

[0067] Furthermore, the capsule 50 may be adhered to the heating member 70 or sandwiched between the heating members 70. This makes it possible to restrict the arrangement of the capsule 50 within the storage section 13. Specifically, the capsule 50 may be held in contact with the heating member 70.

[0068] Furthermore, it is preferable that the storage section 13 is filled with a flavor source that generates an aerosol when heated. By filling the storage section 13 with the flavor source, the variety of flavors and tastes can be expanded. Furthermore, the amount of heating member 70 can be reduced compared to a configuration in which the flavor source is filled in a location other than the storage section 13 having the heating member 70. In other words, by filling the storage section 13 having the heating member 70 with the flavor source, there is no need to prepare a heat-generating member separate from the heating member 70.

[0069] <Second embodiment> Fig. 7 is a diagram showing a longitudinal section of a flavor inhalation stick 2 according to a second embodiment. The stick 2 according to the second embodiment differs from the stick 1 according to the first embodiment in that it has a heated portion 210 corresponding to the heated portion 10. Differences from the first embodiment will be described below. The same reference numerals are used for the same components in the first and second embodiments, and detailed descriptions thereof will be omitted. In this embodiment, the size and arrangement of the heating portion 121 in the flavor inhaler 100 (see Fig. 2) are appropriately changed so as to inductively heat at least a portion of the heating member 70 in the heated portion 210.

[0070] The heated portion 210 differs from the heated portion 10 according to the first embodiment (see FIG. 1 ) in that it includes a solid member 214 that prevents the capsule 50 and the heating member 70 from falling off from the first end surface of the heated portion 210. The heated portion 210 includes a wrapping paper 212, a storage portion 213, and the solid member 214. The heated portion 210 also includes a capsule 50 and a heating member 70 disposed therein. The heated portion 210 is formed, for example, in a cylindrical shape. The heated portion 210 is connected (coupled) to the cooling portion 20 by integrally winding the cooling portion 20 and the heated portion 210 using tipping paper 40. The material constituting the wrapping paper 212 may be, for example, the same as the material constituting the wrapping paper 12 according to the first embodiment. In addition, when the heated portion 210 is made up of two or more members, such as having the storage portion 213 and the solid member 214, it is preferable that each of these two or more members is wrapped in a different wrapping paper before being wrapped together with the wrapping paper 212.

[0071] The storage section 213 is a section that has the heating member 70 and stores the capsule 50. At least a portion of the storage section 213 is stored in the space 141 so that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 2 is held in the holding section 140. The material that forms the storage section 213 can be, for example, the same as the material that forms the storage section 13 according to the first embodiment. The cross section of the storage section 213 is substantially circular, and the diameter of the circle and the perimeter of the cross section can be changed appropriately according to the size of the stick 2. Note that if the cross section is not circular, the above-mentioned diameter is assumed to be a circle having the same area as the area of ​​the cross section, and the diameter of that circle is applied.

[0072] The solid member 214 prevents the capsule 50 and the heating member 70 from falling off the first end face of the heated portion 210 and is disposed on the first side (upstream side) of the storage portion 213. The cross section of the solid member 214 is substantially circular, and the diameter and perimeter of the circle can be appropriately changed to match the size of the stick 2. If the cross section is not circular, the diameter is assumed to be that of a circle having the same area as the cross section, and the diameter of that circle is applied. The material constituting the solid member 214 is not particularly limited, but is preferably a material through which the contents 51 of the capsule 50 can permeate. For example, the material constituting the solid member 214 may be a paper filter filled with sheet-like pulp paper, or a filter formed into a cylindrical shape using a filling such as cellulose acetate fiber, nonwoven fabric, or pulp paper.

[0073] As described above, the stick 2 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a capsule 50 that is destroyed by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a storage section 213 that stores the capsule 50. Note that, from the viewpoint of compact size in the centerline direction, the stick 2 does not need to include the cooling section 20 that cools the vapor and aerosol when the user inhales. Similar to the stick 1, the stick 2 makes it easier to destroy the capsule by heat compared to a configuration in which heating is performed from the outside of the stick 2.

[0074] Furthermore, the stick 2 may preferably include a solid member 214 on the upstream side of the storage section 213. If the end face of the first side (upstream side) of the stick 2 is the end face of the storage section 213, the capsule 50 and heating member 70 stored in the storage section 213 may fall out from the first side of the stick 2. Furthermore, if the capsule 50 stored in the storage section 213 is broken and the content 51 released may leak out from the end face of the first side of the stick 2. In this embodiment, even if the capsule 50 and heating member 70 fall out of the storage section 213, they can be prevented from falling out from the first side of the stick 2. Furthermore, leakage of the content 51 of the capsule 50 into the flavor inhaler 100 can be prevented.

[0075] <Third embodiment> Fig. 8 is a diagram showing a longitudinal section of a flavor inhalation stick 3 according to a third embodiment. The stick 3 according to the third embodiment differs from the stick 2 according to the second embodiment in that the heated portion 310 corresponds to the heated portion 210. Differences from the second embodiment will be described below. The same reference numerals are used for the same components in the second and third embodiments, and detailed descriptions thereof will be omitted. In this embodiment, the size and arrangement of the heating portion 121 in the flavor inhaler 100 (see Fig. 2) are appropriately changed so as to inductively heat at least a portion of the heating member 70 in the heated portion 310.

[0076] The heated portion 310 differs from the heated portion 210 according to the second embodiment (see FIG. 7 ) in that it includes a substrate portion 311 that generates aerosol when heated. The heated portion 310 includes the substrate portion 311, a wrapping paper 312, a storage portion 313, and a solid member 314. The storage portion 313 contains a capsule 50 and a heating member 70. The heated portion 310 is formed, for example, in a cylindrical shape. The heated portion 310 is connected (coupled) to the cooling portion 20 by integrally winding the cooling portion 20 and the heated portion 310 using tipping paper 40. The material constituting the wrapping paper 312 may be the same as the material constituting the wrapping paper 12 according to the first embodiment. In addition, when the heated portion 310 is made up of two or more components, such as the substrate portion 311, the storage portion 313, and the solid member 314, it is preferable that each of these two or more components is wrapped in a different wrapping paper before being wrapped together with the wrapping paper 312.

[0077] The storage section 313 is a section that has the heating member 70 and stores the capsule 50. At least a portion of the storage section 313 is stored in the space 141 so that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 3 is held in the holding section 140. The material that forms the storage section 313 can be, for example, the same as the material that forms the storage section 13 according to the first embodiment. The cross section of the storage section 313 is substantially circular, and the diameter of the circle and the perimeter of the cross section can be changed appropriately according to the size of the stick 3. Note that if the cross section is not circular, the above-mentioned diameter is assumed to be a circle having the same area as the cross section, and the diameter of that circle is used.

[0078] The solid member 314 is a member that prevents the capsule 50 and the heating member 70 from falling off from the first end face of the heated portion 310, and is arranged on the first side (upstream side) of the storage portion 313. The cross section of the solid member 314 is substantially circular, and the diameter of the circle and the perimeter of the cross section can be changed as appropriate to match the size of the stick 3. If the cross section is not circular, the above diameter is assumed to be a circle having the same area as the cross section, and the diameter of that circle is applied. The material that constitutes the solid member 314 can be, for example, the same as the material that constitutes the solid member 214 according to the second embodiment.

[0079] The substrate portion 311 is a portion where aerosol is generated by heating, and contains a flavor source. The substrate portion 311 is disposed on the second side (downstream side) of the storage portion 313. Specifically, the substrate portion 311 is disposed adjacent to the end face on the second side of the storage portion 313. The cross-sectional area and size in the center line direction of the substrate portion 311, as well as the content of the flavor source, can be changed as appropriate to match the size of the stick 3. The flavor source contained in the substrate portion 311 can be the same as the flavor source exemplified in the first embodiment.

[0080] The substrate 311 may include a heat-generating member 80 that generates heat to heat the flavor source. The heat-generating member 80 generates heat due to eddy currents generated within the heat-generating member 80 by the fluctuating electromagnetic field generated by the heating unit 121. The heated heat-generating member 80 heats the surrounding flavor source, generating vapor and aerosol. The material constituting the heat-generating member 80 may be the same as the material constituting the heating member 70. The length, shape, and arrangement of the heat-generating member 80 are not particularly limited and may be modified appropriately to match the size of the substrate 311. The heat-generating member 80 may be one or more. The heat-generating member 80 is not limited to a member that generates heat through electromagnetic induction, but may also be a member that becomes hot when heated by the heating member 70. Specifically, the heat-generating member 80 may be a member with high thermal conductivity (e.g., metal) and whose temperature increases when heated by the heating member 70. The heat-generating member 80 may also be a member whose temperature increases when the stick 3 is heated from the outside.

[0081] When the substrate 311 has a heat-generating member 80, the substrate 311 is accommodated in the space 141 such that the heat-generating member 80 is located within the varying electromagnetic field generated by the heating unit 121 when the stick 3 is held in the holding unit 140. Furthermore, when the substrate 311 having the heat-generating member 80 has a heater that generates heat when the flavor inhaler 100 is powered, the substrate 311 is accommodated in the space 141 such that the heat-generating member 80 is located within the range of heat generated by the heater when the stick 3 is held in the holding unit 140. By positioning the heat-generating member 80 within the varying electromagnetic field generated by the heating unit 121 or within the range of heat generated by the heater, the temperature of the heat-generating member 80 is increased, thereby heating the substrate 311 from the inside. Note that when the substrate 311 does not have a heat-generating member 80, the substrate 311 may be heated by the heat propagating from within the accommodation unit 313 heated by the heating member 70. Furthermore, if the flavor inhaler 100 has a heater that generates heat when power is supplied, the base material portion 311 that does not have the heat-generating member 80 may be heated from the outside by the heater.

[0082] As described above, the stick 3 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a capsule 50 that is destroyed by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a housing portion 313 that houses the capsule 50. Note that, from the viewpoint of compact size in the centerline direction, the stick 3 does not need to include the cooling portion 20 that cools the vapor and aerosol when the user inhales. Similar to the stick 1, the stick 3 makes it easier to destroy the capsule by heat compared to a configuration in which the stick 3 is heated from the outside.

[0083] The stick 3 also includes a substrate 311 that generates aerosol when heated. The storage section 313 is preferably disposed adjacent to the substrate 311. Here, it is assumed that the substrate 311 does not include the heat-generating member 80 and is not heated from the outside by a heater. The heated section 310 of the stick 3 inserted into the holding section 140 of the flavor inhaler 100, which may be exposed to heat from the heating member 70, includes the substrate 311 and the storage section 313. Specifically, at least a portion of the storage section 313 is heated by the heating member 70. Furthermore, heat from within the storage section 313 heated by the heating section 121 may propagate to the substrate 311, which is disposed adjacent to the storage section 313. Since the substrate 311 is disposed adjacent to the storage section 313 that includes the heating member 70, the substrate 311 is heated by heat propagated from the storage section 313 heated by the heating member 70. Furthermore, since the substrate portion 311 is disposed downstream of the storage portion 313, the high-temperature air that has passed through the storage portion 313 passes through the substrate portion 311, further increasing the temperature inside the substrate portion 311. This makes it possible to improve the delivery amount of the aerosol generated from the substrate portion 311.

[0084] It is also assumed that the substrate 311 has a heat-generating member 80, or that the substrate 311 is heated from the outside by a heater. By heating the substrate 311 with the heat-generating member 80 or a heater, the temperature inside the substrate 311 can be further increased. Furthermore, by arranging the substrate 311 having the heat-generating member 80 adjacent to the accommodation section 313, it becomes possible to heat not only the heating member 70 but also the heat-generating member 80 with the varying electromagnetic field of the heating section 121. This eliminates the need for a configuration that generates a varying electromagnetic field for the heat-generating member 80, separate from the heating section 121.

[0085] <Fourth embodiment> Fig. 9 is a diagram showing a longitudinal section of a flavor inhalation stick 4 according to a fourth embodiment. The stick 4 according to the fourth embodiment differs from the stick 3 according to the third embodiment in that the heated portion 410 corresponds to the heated portion 310. Differences from the third embodiment will be described below. The same reference numerals are used for the same components in the third and fourth embodiments, and detailed descriptions thereof will be omitted. In this embodiment, the size and arrangement of the heating portion 121 in the flavor inhaler 100 (see Fig. 2) are appropriately changed so as to inductively heat at least a portion of the heating member 70 in the heated portion 410.

[0086] The heated portion 410 differs from the heated portion 310 according to the third embodiment (see FIG. 8 ) in that a storage portion 413 corresponding to the storage portion 313 is disposed on the second side (downstream side) of the substrate portion 411 corresponding to the substrate portion 311. The heated portion 410 includes a substrate portion 411, a wrapping paper 412, a storage portion 413, and a solid member 414. The heat-generating member 80 is disposed in the substrate portion 411, and a capsule 50 and a heating member 70 are disposed in the storage portion 413. The heated portion 410 is formed, for example, in a cylindrical shape. The heated portion 410 is connected (coupled) to the cooling portion 20 by integrally winding the cooling portion 20 and the heated portion 410 using tipping paper 40. The material constituting the wrapping paper 412 may be the same as the material constituting the wrapping paper 12 according to the first embodiment. In addition, when the heated portion 410 is made up of two or more components, such as a substrate portion 411, a storage portion 413, and a solid member 414, it is preferable that each of these two or more components is wrapped in a different wrapping paper before being wrapped together with the wrapping paper 412.

[0087] The substrate portion 411 is a portion that has the heat generating member 80 and includes a flavor source that generates an aerosol when heated. The substrate portion 411 is arranged on the first side (upstream side) of the storage portion 413. Specifically, the substrate portion 411 is arranged adjacent to the end face of the first side of the storage portion 413. The cross-sectional area and size in the center line direction of the substrate portion 411, as well as the content of the flavor source, can be changed as appropriate to match the size of the stick 4. The flavor source included in the substrate portion 411 can be the same as the flavor source exemplified in the first embodiment.

[0088] The storage section 413 is a portion that includes the heating member 70 and accommodates the capsule 50. The storage section 413 is disposed on the second side of the heated section 410. Specifically, the storage section 413 is disposed adjacent to the second end surface of the base section 411, and is disposed so that the second end surface of the storage section 413 is the second end surface of the heated section 410. At least a portion of the storage section 413 is accommodated in the space 141 so that the heating member 70 is positioned within the fluctuating electromagnetic field generated by the heating section 121 when the stick 4 is held in the holding section 140. The material constituting the storage section 413 may be the same as the material constituting the storage section 13 according to the first embodiment. The cross section of the storage section 413 is substantially circular, and the diameter and perimeter of the circle may be appropriately changed according to the size of the stick 4. If the cross section is not circular, the above-mentioned diameter is determined by assuming a circle having the same area as the cross section, and the diameter of the circle is used.

[0089] The solid member 414 is a member that prevents the capsule 50 and the heating member 70 from falling off from the first end face of the heated portion 410 and is disposed on the first side (upstream side) of the substrate portion 411. The cross section of the solid member 414 is substantially circular, and the diameter and perimeter of the circle can be appropriately changed to match the size of the stick 4. If the cross section is not circular, the diameter is assumed to be that of a circle having the same area as the cross section, and the diameter of that circle is applied. The material constituting the solid member 414 is not particularly limited, but is preferably a material that allows the contents 51 of the capsule 50 to penetrate after passing through the substrate portion 411. The material constituting the solid member 414 can be, for example, the same as the material constituting the solid member 214 according to the second embodiment.

[0090] As described above, the stick 4 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a capsule 50 that is destroyed by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a housing portion 413 that houses the capsule 50. Note that, from the viewpoint of compact size in the centerline direction, the stick 4 does not need to include the cooling portion 20 that cools the vapor and aerosol when the user inhales. Similar to the stick 1, the stick 4 makes it easier to destroy the capsule by heat compared to a configuration in which the stick 4 is heated from the outside.

[0091] The storage section 413 may be disposed adjacent to the downstream side of the substrate section 411. When the storage section 413 is disposed on the first side (upstream side) of the substrate section 411, heat from the heating member 70 is applied to the capsule 50, but the air passing through the storage section 413 is air flowing in from the first end face of the stick 4. On the other hand, when the storage section 413 is disposed on the second side (downstream side) of the substrate section 411, heat from the heating member 70 is applied to the capsule 50, and the air passing through the storage section 413 is air that has passed through the substrate section 411. The temperature of the air that has passed through the substrate section 411 is increased by the heat-generating member 80 and is higher than the temperature of the air flowing in from the first end face of the stick 4. In this embodiment, increasing the temperature of the heat applied to the capsule 50 can improve the destruction efficiency of the capsule 50. Furthermore, when the capsule 50 is destroyed, the delivery efficiency of the flavor and aroma components contained in the contents 51 can be improved.

[0092] <Modifications> (1) Although the embodiments of the present disclosure have been described above, the technical scope of the present disclosure is not limited to the scope described in the above-described embodiments. It is clear from the claims that various modifications or improvements to the above-described embodiments are also included in the technical scope of the present disclosure.

[0093] (2) The heating member may be a member with high thermal conductivity. Here, assume that a non-combustion heating flavor inhaler heats the stick 1 from the outside. The flavor inhaler includes, for example, a heater that generates heat when power is supplied, and when this heater generates heat, the container included in the stick is heated from the periphery of the stick. If the heating member disposed in the container is a member with high thermal conductivity, heat generated from the periphery is easily transferred. An example of a member with high thermal conductivity is a member containing metal. The capsule 50 can be heated by the temperature of the heating member rising due to heating from the periphery. When the stick is heated from the outside, the capsule can be destroyed more easily compared to a configuration in which the container does not have a heating member with high thermal conductivity.
