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

First Embodiment
FIG. 1 is a diagram showing a vertical cross section of a flavor inhalation stick 1 according to a first embodiment.
The flavor inhalation stick (hereinafter, may be referred to as "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 heated section 10 to which heat from the heating member 70 inductively heated by a heating section 121 (see FIG. 2) of a flavor inhaler 100 described later may be applied includes the storage section 13. The capsule 50 and the heating member 70 are disposed in the storage section 13 of the heated section 10.
The stick 1 further includes tipping paper 40 that connects the heated portion 10, the cooling portion 20, and the filter portion 30. The tipping paper 40 has a communication passage 60 that connects the outside and the inside of the stick 1.
Hereinafter, the direction of the center line CL of the heated portion 10 may be referred to as the "center line direction." The stick 1 has the heated portion 10, the cooling portion 20, and the filter portion 30 arranged in this order in the center line direction, and the tipping paper 40 wrapped around them to integrate them.

In this specification, one end side in the center line direction (left side in FIG. 1) may be referred to as the first side, and the other end side in the center line direction (right side in FIG. 1) may be referred to as the second side. The first side is the end side that is inserted into the flavor inhaler 100. The second side is the end side opposite the first side that the user holds in their mouth to inhale. 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."

(Flavor suction 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 the present embodiment includes the stick 1 according to the first embodiment and a non-combustion heating type flavor inhaler 100 that heats from the inside the heated portion 10 of the stick 1. The stick 1 according to the first embodiment is inserted into the non-combustion heating type flavor inhaler 100 for use.
As shown in Fig. 2, the main body 130 of the flavor inhaler 100 includes a heating unit 121 for heating the heating member 70 of the stick 1. The main body 130 also includes a power supply unit 131 for storing power and supplying power to each component of the main body 130, a sensor unit 132 for detecting various information related to the main body 130, and a notification unit 133 for notifying the user of the information. The main body 130 also includes a storage unit 134 for storing various information for the operation of the main body 130, a communication unit 135 for transmitting and receiving information between the main body 130 and other devices, and a control unit 136 for controlling the overall operation of the main body 130. In the flavor inhaler 100, the stick 1 inserted from the insertion port 142 of the holding unit 140 is inhaled by the user while being 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, for example, in a straight line or in an L-shape.

The power supply unit 131 supplies power for operating the heating unit 121. The power supply unit 131 supplies, for example, a DC current.
The control unit 136 controls the heating unit 121. The control unit 136 has, for example, a DC/AC inverter for supplying a high-frequency AC current to the heating unit 121. When the flavor inhaler 100 is operated, a high-frequency AC current passes through an induction coil that forms a 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, 1 MHz to 30 MHz, preferably 2 MHz to 10 MHz, more preferably 5 MHz to 7 MHz.

The heating unit 121 is an inductor that inductively heats the heating member 70. The heating unit 121 is disposed so as to cover the holding unit 140. Specifically, the heating unit 121 is disposed 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 a current is supplied. The fluctuating electromagnetic field of the heating unit 121 may be generated, for example, when a switch (not shown) is pressed by the user, or may be generated automatically when the stick 1 is held in the space 141 of the holding unit 140. Then, an eddy current is generated in the heating member 70 located in the fluctuating electromagnetic field by the heating unit 121, and as a result, the heating member 70 is heated. Further heating is provided by magnetic hysteresis loss in 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 pass through the cooling unit 20 and the filter unit 30 and are inhaled by the user.
In addition, the supply of current to the heating unit 121 may be continued, for example, during a period during which the sensor unit 132 detects that the user has performed inhalation, or may be stopped when the sensor unit 132 detects that the user has performed a specified operation.

(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. The cross section of the stick 1 is, for example, substantially circular, and the outer diameter and the size in the center line direction can be appropriately changed according to a desired size.

The airflow resistance in the center line direction per stick 1 is not particularly limited, but from the viewpoint of ease of inhalation, it is usually 100 mmH ₂ O or less, preferably 80 mmH ₂ O or less, and more preferably 60 mmH ₂ O or less. Moreover, the airflow resistance in the center line direction per stick 1 is usually 8 mmH ₂ O or more, preferably 10 mmH ₂ O or more, and more preferably 12 mmH ₂ O or more.
The airflow resistance of the stick 1 is measured according to the ISO standard method (ISO6565), for example, using a filter airflow resistance meter 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 expressed in mmH ₂ O. It is known that the relationship between the size in the center line direction and the airflow resistance of a non-combustion heating type flavor inhalation article is proportional at normal sizes (e.g., 5 mm to 200 mm). Specifically, if the size in the center line direction of a non-combustion heating type flavor inhalation article is doubled, the airflow resistance is doubled.

((Cooling section 20))
In the example shown in Fig. 1, the cooling unit 20 is disposed adjacent to the heated unit 10 and the filter unit 30, and is a part formed so that the cross section of a cylinder or the like is hollow (hollow) by wrapping the sheet 21 around it. Since the cooling unit 20 is a cylindrical member, it is possible to generate an aerosol by cooling the steam generated by heating the heated unit 10. The cooling unit 20 is, for example, a paper tube formed by wrapping the sheet 21 made of paper around it.

The cross section of the cooling section 20 is substantially circular, and its outer diameter can be appropriately changed according to 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 above 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 it is desirable for the size to be such that a sufficient cooling effect can be ensured while obtaining a good flavor and that loss due to the generated steam and aerosol adhering to the sheet 21 can be suppressed.

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

((Filter unit 30))
The filter unit 30 is located on the second side (downstream side) of the cooling unit 20. The filter unit 30 has a filter 31 through which the aerosol passes.
The filter unit 30 is connected (coupled) to the second end of the cooling unit 20 by integrally winding up the first end of the filter unit 30 using tipping paper 40 described later. The filter 31 may also have a winding paper 32 wound between the outer circumferential surface of the filter 31 and the tipping paper 40.

The cross section of the filter 31 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the stick 1. 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 applied.
1, the filter unit 30 has a plain filter composed of a single filter 31, but is not limited to this. The filter unit 30 may have a multi-segment filter composed of multiple filters, such as a dual filter composed of two types of filters or a triple filter composed of three types of filters. When the filter unit 30 has a multi-segment filter, it is preferable that the wrapper 32 is formed by winding each of the multiple filters and then winding them together with another wrapper.

The airflow resistance per 12 mm in the center line direction of the filter portion 30 is not particularly limited, but is usually 40 _mmH2O to 300 _mmH2O , preferably 70 _mmH2O to 280 _mmH2O , and more preferably 90 _mmH2O to 260 _mmH2O .
The airflow resistance of the filter unit 30 is measured according to the ISO standard method (ISO6565), for example, using 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 flowed 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 surface of the filter unit 30. The unit is generally expressed in mmH ₂ O. It is known that the relationship between the size in the center line direction of the filter unit 30 and the airflow resistance is proportional at normal sizes (for example, 5 mm to 200 mm). Specifically, if the size in the center line direction of the filter unit 30 is doubled, the airflow resistance is doubled.

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 functions of a filter include reducing unpleasant sensations such as irritation, and reducing nicotine and tar, but it is not necessary for the filter to have all of these functions. Furthermore, in the stick 1, which tends to produce fewer components and has a lower aerosol source filling rate compared to cigarette products, other important functions include preventing the aerosol source from falling off while suppressing the filtering function, and adjusting the air resistance to provide appropriate ease of inhalation.

The filter material constituting the filter 31 is, for example, a filler such as acetate, charcoal, cellulose fiber, nonwoven fabric, or pulp paper molded into a column shape. It is also possible to use a paper filter filled with pulp paper in sheet form. In addition, the filter 31 may be appropriately supplemented with, for example, known fragrances (e.g., menthol), adsorbents, granular activated carbon, fragrance retention materials, etc.

The material of the wrapping paper 32 can be, for example, one whose main component is pulp. In addition to being made from wood pulp such as softwood pulp or hardwood pulp, the pulp may also be made by mixing non-wood pulp that is generally used in wrapping papers for tobacco products, such as flax pulp, hemp pulp, sisal pulp, and esparto. These pulps may be used alone or in combination of multiple types in any ratio. They may also contain fillers such as calcium carbonate.

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

The embodiment of the paper roll 32 is not particularly limited, and may include one or more rows of adhesive-containing seams. 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.
Additionally, the wrapper 32 may be either coated or uncoated, but is preferably coated with a desired material from the standpoint of imparting functions such as strength and structural rigidity.
The wrapper 32 may be a plastic, polymeric sheet, etc. The wrapper 32 may be a porous member having a plurality of pores formed therein.

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

The basis weight of the tipping paper 40 is not particularly limited, but is usually from 32 gsm to 40 gsm, preferably from 33 gsm to 39 gsm, and more preferably from 34 gsm to 38 gsm.
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 expressed as the flow rate ( ^cm3 ) of gas passing through an area of 1 ^cm2 per minute when the differential pressure between both sides of the paper is 1 kPa. 1 Coresta unit (1 Coresta unit, 1 C.U.) is ^cm3 /(min· ^cm2 ) under 1 kPa.

A coating agent may be added to at least one of the two surfaces, the front surface and the back surface, of the tipping paper 40. There are no particular limitations on the coating agent for the tipping paper 40, but a coating agent that can form a film on the surface and reduce the permeability of liquids is preferred.
Also, a part of the outer surface of the tipping paper 40 may be covered with a known lip release material. The lip release material refers to a material configured to assist in the easy release of contact between the lips and the tipping paper 40 without substantial adhesion when the user holds the filter portion 30 of the stick 1 in the mouth. The lip release material may contain, 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.

((Communication path 60))
The communication passage 60 communicates between the outside and the inside of the stick 1. Therefore, the communication passage 60 allows air outside the stick 1 to flow into the inside when inhaled.
The shape of the communication passage 60 can be, for example, a circular cylinder, an elliptical cylinder, a polygonal prism, a polygonal prism with rounded corners, or a mortar shape.
The communication passages 60 are formed by through holes (also referred to as "ventilation filters (Vf)" in this technical field) formed at least in the region of the tipping paper 40 where the cooling section 20 is arranged. In the example shown in Fig. 1, a plurality of communication passages 60 are formed in the cooling section 20, and are formed in the circumferential direction of the cooling section 20 and concentrically.
The communication passages 60 are not limited to being formed around the entire circumference of the cooling section 20, but may be formed in a portion of the circumference of the cooling section 20. In addition, if a plurality of concentric communication passages 60 are regarded as one communication passage group, the number of communication passage groups may be one or may be two or more.

The existence of a 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 steam and air that flows in from the heated section 10. Furthermore, when the heated section 10 is heated, the steam that is generated using the aerosol as a condensation nucleus comes into contact with air from the outside and its temperature drops, liquefying, promoting the generation of the aerosol.

It is preferable that the position of the communication passage 60 in the center line direction be a position where air can flow in from outside the stick 1, for example a position within the area protruding from the insertion port 142 when the stick 1 is held in the holding portion 140 of the flavor inhaler 100.
In addition, 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 section 20 and the filter section 30 in the direction of the first side (upstream side) from the viewpoint of improving the delivery efficiency of aerosols generated by heating. 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. In addition, in order to ensure the cooling function of the cooling section 20, the position of the communication passage 60 in the center line direction is preferably within 15 mm in the direction of the first side (upstream side) from the boundary between the cooling section 20 and the filter section 30. The position of the communication passage 60 in the center line direction is more preferably within 10 mm, and even more preferably within 7 mm.
In addition, the position of the communication passage 60 in the center line direction is preferably 24 mm or more away from the end face on the second side of the stick 1 in the direction of the first side (upstream side) from the viewpoint of improving the delivery efficiency of aerosols generated by heating. The position of the communication passage 60 in the center line direction is more preferably 24.5 mm or more away, even more preferably 25 mm or more away, and even more preferably 25.5 mm or more away. In addition, in order to ensure the cooling function of the cooling unit 20, the position of the communication passage 60 in the center line direction is preferably within 35 mm from the end face on the second side of the stick 1 in the direction of the first side (upstream side). The position of the communication passage 60 in the center line direction is more preferably within 30 mm, and even more preferably within 27 mm.
In addition, when the size of the cooling part 20 in the center line direction is 20 mm or more, from the viewpoint of improving the delivery efficiency of aerosols generated by heating, it is preferable that the position of the communication passage 60 in the center line direction is within 16 mm in the direction of the second side (downstream side) from the boundary between the heated part 10 in which the heating member 70 is accommodated and the cooling part 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. In addition, from the viewpoint of ensuring the cooling function of the cooling part 20, the position of the communication passage 60 in the center line direction is preferably 5 mm or more away from the boundary between the heated part 10 and the cooling part 20 in the direction of the second side (downstream side). 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.

The communication passage 60 is provided so that the air inflow rate from the communication passage 60 when inhaled at 17.5 ml/sec by an automatic smoking machine is 10% by volume or more and 90% by volume or less. This "air inflow rate" is the volume rate of air inflowing from the communication passage 60 when the rate of air inhaled from the end of the second side 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, 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 communication passages 60 per communication passage group from the range of 5 to 50, selecting the diameter of the opening of the communication passage 60 from the range of 0.1 mm to 0.5 mm, and combining these selections.
The air inflow ratio can be measured by a method conforming to ISO9512 using a winding quality measuring device (for example, SODIMAX D74/SODIM manufactured by SAS).

The communication passage 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 section 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 making such a stick 1, a tipping paper 40 with a through hole that overlaps with the through hole in the sheet 21 may be prepared and wound, but from the viewpoint of ease of manufacture, it is preferable to make a stick 1 without a communication passage 60 and then open a hole that penetrates 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 on the sheet 21 may be an intensity that 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 hole in the tipping paper 40 and the pores in the sheet 21 form a communication passage 60 that connects the outside of the stick 1 to the inside of the cooling section 20.

(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 an aerosol source without containing a flavor component. Examples of the aerosol source include glycerin, propylene glycol, triacetin, 1,3-butanediol, and the like, or a combination of these.
The capsule 50 is disposed inside the storage section 13. The position of the capsule 50 in the vertical cross section of the storage section 13 is preferably such that the contents 51 do not leak out from the first end face and the second end face of the storage section 13 when the capsule 50 is broken. In other words, the capsule 50 is preferably disposed at a position where the diffusion of the contents 51 is contained within the storage section 13.

The shape of the capsule 50 is not particularly limited, and may be, for example, a spherical shape, a cylindrical shape, a truncated cone shape, etc. Furthermore, a plurality of capsules 50 may be arranged.
The size of the capsule 50 is not particularly limited, and is usually 2 mm to 5 mm in diameter. The size of the capsule 50 is preferably such that the capsule 50 does not significantly increase the airflow resistance of the stick 1 compared to a stick without the capsule 50, while still containing a sufficient amount of the contents 51. This makes it possible to achieve an appropriate airflow resistance even in the stick 1 in which the capsule 50 is not broken.

The state of the contents 51 is not particularly limited and may be liquid, gel, solid, etc. The state of the contents 51 may also change. For example, the contents 51 may be solid at room temperature, but may change to liquid due to heat from the heating member 70.
When the contents 51 are liquid or gel-like, the boiling point of the contents 51 is preferably higher than the temperature at which the coating 52 melts.
Furthermore, when the released contents 51 are liquid or gel-like, the viscosity of the contents 51 is preferably such that the contents 51 permeate the storage section 13 and do not leak out from the first end face and the second end face of the storage section 13. Furthermore, the amount of liquid in the contents 51 is preferably such that the contents 51 permeate the storage section 13 sufficiently and do not reach the first end face of the stick 1 and spill into the flavor inhaler 100. This makes it possible to prevent the contents 51 from seeping out to the outside of the stick 1 when the contents 51 spread within the storage section 13 while imparting a new smoking flavor.

The flavor component contained in the contents 51 is, for example, a flavor component. Specifically, the contents 51 is, for example, a flavor component whose flavor component volatilizes when heated.
The flavoring is not particularly limited, and examples thereof include powder flavorings and oil-based flavorings.

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, and a state in which flavor and aroma components volatilized from the contents 51 permeate the coating 52.
The coating 52 has a strength such that it is destroyed when heat is applied thereto by the heating member 70. The coating 52 also has a strength such that it is not destroyed when heat such as human body temperature is applied thereto.

((Heated part 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 of FIG.
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 the capsule 50 and a heating member 70 that heats the capsule 50 arranged therein. 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.
In addition, the heated portion 10 may not have the wrapping paper 12, and may be connected (coupled) to the cooling portion 20 by winding up the cooling portion 20 and the containing portion 13 together.

The storage unit 13 is a portion that has the heating member 70 and stores the capsule 50. At least a portion of the storage unit 13 is stored in the space 141 when the stick 1 is held by the holding unit 140. Specifically, at least a portion of the storage unit 13 is stored in the space 141 such that the heating member 70 is located within the varying electromagnetic field generated by the heating unit 121 when the stick 1 is held by the holding unit 140.
The cross section of the container 13 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the stick 1. If the cross section is not circular, the above 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 storage section 13 may be a hollow (hollow) tubular 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 the material constituting the storage section 13 include cellulose acetate fiber, nonwoven fabric, pulp paper, processed products obtained by forming raw materials containing flavor and taste components into a sheet shape (hereinafter referred to as "flavor sheet"), processed products obtained by forming resin into a sheet shape (hereinafter referred to as "resin sheet"), plastics molded into a desired shape, and the like. In addition, when two or more components are filled in the storage section 13, the multiple components may have different compositions, physical properties, sizes, shapes, and the like.

Here, a case will be described in which the storage section 13 is made of a sheet-like member such as pulp paper, a flavor sheet, a resin sheet, or the like (hereinafter referred to as a "sheet member").
When the storage section 13 is composed of one sheet member, for example, a mode (so-called gathered sheet) can be used in which a sheet member having one side of the same size as the size of the storage section 13 in the center line direction is filled in a state where it is folded back multiple times horizontally to the center line direction of the storage section 13. Another mode can also be used in which a sheet member having one side of the same size as the size of the storage section 13 in the center line direction is filled in a state where it is wound in a direction perpendicular to the center line direction of the storage section 13.
In the case where the storage section 13 is composed of two or more sheet members, for example, a plurality of sheet members, one side of which has a size approximately equal to the size of the storage section 13 in the center line direction, are packed in a state of being wound in a direction perpendicular to the center line direction 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 equal to the size of the storage section 13 in the center line direction is filled with the sheet material cut approximately horizontally to the center line direction.

Furthermore, when the storage section 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 section 13 may be formed by filling it with a 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 section 13 can be maintained. By filling it with a sheet member to which the capsules 50 and the heating member 70 are fixed, it is easy to adjust the arrangement of the capsules 50 and the heating member 70 in the storage section 13 to the desired arrangement.

The container 13 may also be a location where an aerosol is generated by heating, and may contain, for example, a flavor source.
The flavor source contained in the storage section 13 may be derived from tobacco, such as a processed product obtained by forming tobacco shreds or tobacco raw material into a granular, sheet, or powder form, or dried tobacco leaves (dried tobacco leaves). The flavor source may also include a non-tobacco-derived product made from a plant other than tobacco (e.g., mint and herbs). The aerosol source may also include a flavoring. The flavor source may also include dried tobacco leaves and a flavoring-containing material in which a flavoring is contained in a polysaccharide gel. The type of flavoring is not particularly limited, and menthol is particularly preferred from the viewpoint of imparting a good flavor. The flavoring contained in the flavoring source may be used alone or in combination of two or more types. In addition, when the flavor inhaler 100 is a medical inhaler, the flavoring source may include a medicine for the patient to inhale.
The components constituting the flavor source are not limited to solid materials, and 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, and may be, for example, a capsule containing a liquid material.

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 the types of tobacco include flue-cured tobacco, burley tobacco, oriental tobacco, native tobacco, other Nicotiana tabacum varieties, Nicotiana rustica varieties, and mixtures thereof. The mixtures are appropriately blended to achieve the desired flavor.
In addition, even when the flavor source is derived from tobacco, various extracts from natural products and/or their constituents may be included depending on the application. Examples of the extracts and/or their constituents include glycerin, propylene glycol, triacetin, 1,3-butanediol, and mixtures thereof.

Furthermore, when the flavor source contained in the storage section 13 is tobacco shreds or a processed product formed from tobacco raw material 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 produce tobacco pulverized material, homogenizing this using known means, and processing it into a sheet. The tobacco sheet is an example of a sheet member. The number of tobacco sheets may be one or two or more.

The configuration of the cigarette paper 12 is not particularly limited and may be a general embodiment, for example, one containing pulp as a main component. The pulp may be made from wood pulp such as softwood pulp or hardwood pulp, or may be made by mixing non-wood pulp generally used for cigarette papers 12 for tobacco products, such as flax pulp, hemp pulp, sisal pulp, and esparto. The types of pulp that can be used include chemical pulp produced by the kraft cooking method, acidic/neutral/alkaline sulfite cooking method, soda salt cooking method, etc., ground pulp, chemi-ground pulp, thermomechanical pulp, etc. Furthermore, the cigarette paper 12 may be, for example, a tobacco sheet, a flavor sheet, a resin sheet, etc.
The cigarette paper 12 may contain a filler, for example, calcium carbonate from the viewpoint of improving whiteness and opacity and increasing the heating rate. The cigarette paper 12 may also contain various auxiliary agents, and may have a coating agent added to at least one of its two surfaces, the front surface and the back surface.

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 is usually 10 μm or more, preferably 20 μm or more, and more preferably 30 μm or more, from the viewpoints of rigidity, breathability, and ease of adjustment during papermaking. 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.

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 wound in a cylindrical shape with the wrapping paper 12, for example, an end of the wrapping paper 12 and an end of the wrapping paper 12 on the opposite side are overlapped by about 2 mm in the circumferential direction and glued together to form a cylindrical paper tube shape filled with the material constituting the storage section 13. In addition, when a cylindrical paper tube is formed in advance with the wrapping paper 12, the material constituting the storage section 13 may be filled in the paper tube formed by the wrapping paper 12, for example.

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 that are generated in the heating member 70 by a fluctuating electromagnetic field generated by the heating unit 121. The heated heating member 70 heats the capsule 50 around it, destroying the capsule 50.
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 a 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 a nickel alloy (permalloy) is covered with two layers of stainless steel.

The heating member 70 extends within the housing portion 13 along the center line direction (longitudinal direction) of the stick 1. The housing portion 13 may have one heating member 70, or two or more heating members 70.
3, the storage unit 13 stores the capsules 50 with one heating member 70 disposed toward the center in the cross section. Specifically, the heating member 70 is a thin plate extending in the center line direction and disposed so that its cross section is flat (approximately linear) in the cross section of the storage unit 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 in the storage unit 13.
Moreover, from the viewpoint of improving the heating efficiency of the capsule 50, it is preferable that the heating member 70 is in contact with the capsule 50. In other words, it is preferable that the capsule 50 is disposed so as to be in contact with the heating member 70. Furthermore, it is preferable that the capsule 50 is adhered to the heating member 70. Note that the location of the capsule 50 is not limited to near the center of the cross section of the storage section 13, and may be near the outer periphery of the cross section of the storage section 13, specifically near the wrapping paper 12, as long as the capsule 50 can be heated by the heating member 70.
By the heating member 70 inside the storage section 13 generating 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.

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 the diameter of the storage section 13 as shown in FIG. 3, or may be greater than the diameter. The thickness of the heating member 70 is not particularly limited, but is preferably thin from the viewpoint of suppressing an increase in air resistance due to the heating member 70. The shape of the heating member 70 is not limited to a rectangle, and at least one end in the center line direction of the heating member 70 may be sharp. The heating member 70 may have a convex portion that protrudes in the thickness direction or a concave portion that is recessed in the thickness direction. The cross-sectional shape of the heating member 70 may be polygonal, circular, or elliptical.

From the viewpoint of preventing the contents 51 from leaking out 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 holes through which the contents 51 can enter. 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 and is formed by surface processing such as pasting a sheet having 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-processed such as pasting a sheet having better water absorption. An example of the "sheet having better water absorption" is a porous sheet. In addition, for example, the heating member 70 may have a recess formed on its surface that can serve as a tray 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 to the outside of the stick 1. In addition, the volatilization of the flavor and aroma components contained in the contents 51 can be promoted.

The heating member 70 is not limited to the example shown in Fig. 3. Specifically, the heating member 70 does not have to be only one as shown in Fig. 3, and the cross-sectional shape of the heating member 70 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 the line III-III in FIG.
In the example shown in Fig. 4, the storage section 13 stores the capsules 50 in a state where the heating members 70 are arranged so that each of them 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 members 70 have a bend such as a curve, it is preferable that the heating members 70 contact the wrapping paper 12 at two or more points in the cross section of the storage section 13 from the viewpoint of suppressing the movement of the heating members 70 themselves.
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. The location 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.

By having multiple heating members 70 in the storage section 13, the heating efficiency of the capsule 50 in the storage section 13 can be improved compared to a configuration having only one heating member 70. Also, by sandwiching the capsule 50 between multiple heating members 70, the surface area of the heating member 70 in contact with the capsule 50 can be increased, improving the heating efficiency of the capsule 50. Furthermore, by having the cross-sectional shape of the heating member 70 bent, the surface area of the heating member 70 can be increased, improving the heating efficiency in the storage section 13, compared to a configuration in which the cross-sectional shape of the heating member 70 is flat.

FIG. 5 is a view showing another example of a cross section of the flavor inhalation stick 1 according to the first embodiment taken along the line III-III in FIG.
5, the storage unit 13 stores the capsules 50 in a state where one heating member 70 is arranged so as to be curved at multiple points. Specifically, the heating members 70 are arranged so that their cross-sectional shape is Ω-shaped in the transverse section of the storage unit 13, and the capsules 50 are stored sandwiched between the heating members 70.
Since the cross-sectional shape of the heating member 70 is Ω-shaped, even if there is only one heating member 70, it is possible to increase the surface area of the heating member 70 to the same extent as when two heating members 70 having an S-shaped cross-sectional shape are arranged, and improve the heating efficiency inside the storage section 13. Furthermore, when the capsule 50 is sandwiched between the heating members 70, it is not necessary to adjust the positional relationship of each heating member 70, which is necessary when sandwiching the capsule 50 between multiple heating members 70.

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 the line III-III in FIG.
In the example shown in Fig. 6, the storage section 13 stores the capsule 50 in a state in which a plurality of heating members 70 are arranged so as to be dispersed. Specifically, a plurality of heating members 70 having a circular cross-sectional shape are arranged in the transverse section of the storage section 13, and the capsule 50 is stored so as to be surrounded by the heating members 70. The capsule 50 may be in contact with a plurality of heating members 70. The heating member 70 is not particularly limited, and may have a cross-sectional shape of an ellipse, a polygon, or the like, may be a columnar shape extending in the direction of the center line, or may be granular.
By distributing the heating members 70, the entire storage unit 13 can be efficiently heated. Furthermore, the heating efficiency of the capsule 50 can be improved. In addition, by distributing 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.

As explained above, the stick 1 is a flavor inhalation stick that is heated by being inserted into the flavor inhaler 100, and includes a capsule 50 that is broken by heat to release at least the flavor components, a heating member 70 for heating the capsule 50, and a storage section 13 for storing the capsule 50. 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.

Here, we consider a case where the heating member 70 generates heat through induction heating. The user inserts the stick 1, with the capsule 50 still intact, into the holding section 140 of the flavor inhaler 100. The heating member 70 in the storage section 13 is heated by eddy currents generated in the heating member 70 by the fluctuating electromagnetic field of the heating section 121, and generates heat. As the heating member 70 generates heat, heat is applied to the capsule 50 from inside the storage section 13. As a result, the heat applied to the capsule 50 placed inside the storage section 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 makes it easier to destroy the capsule by heat compared to a configuration in which heating is applied from the outside of the stick 1.

For example, the heating member 70 may be in the form of a sheet.
It is easy to form the cross-sectional shape of the heating member 70 in the transverse 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, it is possible to improve the heating efficiency of the heating member 70 for the capsule 50. Since it is easy for the heat from the heating member 70 to be applied to the capsule 50, it is possible to easily destroy the capsule by heat.

Also, it is preferable that the heating member 70 is a porous body, or that a porous sheet is attached to the surface of the heating member 70 .
A place for the contents 51 released from the capsule 50 to go is secured, and the contents 51 are prevented from leaking out to the outside of the stick 1.

In addition, it is preferable that a plurality of heating members 70 are disposed in a dispersed manner in the housing portion 13 .
The entire storage unit 13 is efficiently heated, and heat is easily applied to the capsule 50. In addition, since the heating members 70 are distributed, 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.

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

Furthermore, the capsule 50 may be adhered to the heating member 70 or sandwiched between the heating member 70 .
It is possible to restrict the arrangement of the capsule 50 in the storage unit 13. Specifically, it is possible to hold the capsule 50 in a state where it is in contact with the heating member 70.

The storage section 13 may also be filled with a flavor source that generates an aerosol when heated.
Filling the storage section 13 with the flavor source can expand the variety of flavors and tastes. Also, the amount of the 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, filling the storage section 13 having the heating member 70 with the flavor source eliminates the need to prepare a heat generating member separate from the heating member 70.

Second Embodiment
FIG. 7 is a diagram showing a vertical cross section of the flavor inhalation stick 2 according to the second embodiment.
The stick 2 according to the second embodiment is different from the stick 1 according to the first embodiment in that the heated portion 210 corresponds to the heated portion 10. The differences from the first embodiment will be described below. The same reference numerals are used for the same parts in the first and second embodiments, and detailed descriptions thereof will be omitted.
In this embodiment, in the flavor inhaler 100 (see FIG. 2), the size and arrangement of the heating part 121 are appropriately changed so as to inductively heat at least a part of the heating member 70 in the heated part 210.

The heated portion 210 differs from the heated portion 10 (see FIG. 1) according to the first embodiment in that it has a solid member 214 that prevents the capsule 50 and the heating member 70 from falling off from the end face on the first side of the heated portion 210. The heated portion 210 has a wrapping paper 212, a storage portion 213, and a solid member 214. The heated portion 210 also has a capsule 50 and a heating member 70 arranged therein. The heated portion 210 is formed, for example, in a cylindrical shape. The heated portion 210 is connected (linked) to the cooling portion 20 by winding the cooling portion 20 and the heated portion 210 together using tipping paper 40. The material constituting the wrapping paper 212 can be, for example, the same as the material constituting the wrapping paper 12 according to the first embodiment. In addition, if the heated portion 210 is made up of two or more members, such as the storage portion 213 and the solid member 214, it is preferable that each of these two or more members is wrapped in a separate wrapping paper before being wrapped together in the wrapping paper 212.

The storage section 213 is a section that has the heating member 70 and stores the capsule 50. At least a part of the storage section 213 is stored in the space 141 such that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 2 is held by the holding section 140.
The material constituting the storage section 213 can be, for example, the same as the material constituting 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. 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 the circle is applied.

The solid member 214 is a member that prevents the capsule 50 and the heating member 70 from falling off from the end face on the first side of the heated portion 210 , and is disposed on the first side (upstream side) with respect to the containing portion 213 .
The cross section of the solid member 214 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the stick 2. 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 applied.
The material constituting the solid member 214 is not particularly limited, but is preferably a material through which the content 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 from a filler such as cellulose acetate fiber, nonwoven fabric, or pulp paper.

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 broken by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a storage section 213 for storing the capsule 50. From the viewpoint of compact size in the center line direction, the stick 2 does not need to include a cooling section 20 that cools the vapor and aerosol when the user inhales.
According to the stick 2, like the stick 1, it is possible to easily destroy the capsules by heat, compared to a configuration in which heating is performed from the outside of the stick 2.

The stick 2 may also include a solid member 214 upstream of the container 213 .
When 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 the heating member 70 stored in the storage section 213 may fall off from the first side of the stick 2. Furthermore, the capsule 50 stored in the storage section 213 may be 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 the heating member 70 fall off from the storage section 213, they can be prevented from falling off from the first side of the stick 2. Furthermore, the content 51 of the capsule 50 can be prevented from leaking into the flavor inhaler 100.

Third Embodiment
FIG. 8 is a diagram showing a vertical cross section of a flavor inhalation stick 3 according to the third embodiment.
The stick 3 according to the third embodiment is different from the stick 2 according to the second embodiment in that the heated portion 310 corresponds to the heated portion 210. The differences from the second embodiment will be described below. The same reference numerals are used for the same parts in the second and third embodiments, and detailed descriptions thereof will be omitted.
In this embodiment, in the flavor inhaler 100 (see FIG. 2), the size and arrangement of the heating part 121 are appropriately changed so as to inductively heat at least a part of the heating member 70 in the heated part 310.

The heated portion 310 differs from the heated portion 210 of the second embodiment (see FIG. 7) in that it has a substrate portion 311 that generates an aerosol when heated. The heated portion 310 has a substrate portion 311, a wrapping paper 312, a storage portion 313, and a solid member 314. A capsule 50 and a heating member 70 are disposed in the storage portion 313. The heated portion 310 is formed, for example, in a cylindrical shape. The heated portion 310 is connected (linked) to the cooling portion 20 by winding the cooling portion 20 and the heated portion 310 together using tipping paper 40. The material constituting the wrapping paper 312 can be, for example, the same as the material constituting the wrapping paper 12 of 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 separate wrapping paper before being wrapped together in the wrapping paper 312.

The storage section 313 is a section that has the heating member 70 and stores the capsule 50. At least a part of the storage section 313 is stored in the space 141 such that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 3 is held by the holding section 140.
The material constituting the storage section 313 can be, for example, the same as the material constituting 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. 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 the circle is applied.

The solid member 314 is a member that prevents the capsule 50 and the heating member 70 from falling off from the end face on the first side of the heated portion 310 , and is disposed on the first side (upstream side) with respect to the containing portion 313 .
The cross section of the solid member 314 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the 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 constituting the solid member 314 can be, for example, the same as the material constituting the solid member 214 according to the second embodiment.

The base material portion 311 is a portion where an aerosol is generated by heating, and contains a flavor source. The base material portion 311 is disposed on the second side (downstream side) of the storage portion 313. Specifically, the base material portion 311 is disposed adjacent to an end surface of the storage portion 313 on the second side.
The cross-sectional area and centerline size of the base material portion 311, and the content of the flavor source may be appropriately changed according to the size of the stick 3. The flavor source contained in the base material portion 311 may be the same as the flavor source exemplified in the first embodiment.

The base material portion 311 may have 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 in the heat generating member 80 by the fluctuating electromagnetic field generated by the heating section 121. The heated heat generating member 80 heats the flavor source around it, generating vapor and aerosol.
The material constituting the heat generating member 80 can be, for example, 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 can be changed as appropriate according to the size of the base material portion 311. The heat generating member 80 may be one or two or more.
The heat generating member 80 is not limited to a member that generates heat by electromagnetic induction, but may be a member that becomes hot when heated by the heat from the heating member 70. Specifically, the heat generating member 80 may be a member that has high thermal conductivity (e.g., metal) and whose temperature increases when heat from the heating member 70 is applied to it. The heat generating member 80 may also be a member whose temperature increases when the stick 3 is heated from the outside.

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 fluctuating electromagnetic field generated by the heating unit 121 when the stick 3 is held in the holding unit 140. 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 a range to which the heat from the heater is applied when the stick 3 is held in the holding unit 140. By positioning the heat generating member 80 within the fluctuating electromagnetic field generated by the heating unit 121 or within a range to which the heat from the heater is applied, the temperature of the heat generating member 80 can be increased and the substrate 311 can be heated from the inside.
In addition, when the base material 311 does not have the heat generating member 80, the base material 311 may be heated by the heat propagating from within the storage section 313 heated by the heating member 70. In addition, when the flavor inhaler 100 has a heater that generates heat when power is supplied, the base material 311 that does not have the heat generating member 80 may be heated from the outside by the heater.

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 broken by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a storage section 313 for storing the capsule 50. From the viewpoint of compact size in the center line direction, the stick 3 does not need to include a cooling section 20 that cools the vapor and aerosol when the user inhales.
According to the stick 3, like the stick 1, it is possible to easily destroy the capsules by heat, compared to a configuration in which the heat is applied from the outside of the stick 3.

The stick 3 further includes a base material 311 that generates an aerosol when heated. The container 313 is preferably disposed adjacent to the base material 311.
Here, it is assumed that the substrate 311 does not have the heat generating member 80 and is not heated from the outside by a heater. Of the stick 3 inserted into the holding part 140 of the flavor inhaler 100, the heated part 310 that may be subjected to heat from the heating member 70 includes the substrate 311 and the storage part 313. Specifically, at least a part of the storage part 313 is heated by the heating member 70. In addition, there is a possibility that heat in the storage part 313 heated by the heating part 121 will propagate to the substrate 311 disposed adjacent to the storage part 313.
Since the substrate portion 311 is disposed adjacent to the storage portion 313 having the heating member 70, the substrate portion 311 is heated by heat propagated from the storage portion 313 heated by the heating member 70. Furthermore, since the substrate portion 311 is disposed downstream of the storage portion 313, the air with a high temperature that has passed through the storage portion 313 passes through the substrate portion 311, and the temperature inside the substrate portion 311 increases. This makes it possible to improve the amount of aerosol delivered from the substrate portion 311.

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 by the heat-generating member 80 or a heater, the temperature inside the substrate 311 can be further increased. In addition, by arranging the substrate 311 having the heat-generating member 80 adjacent to the housing 313, it becomes possible to heat not only the heating member 70 but also the heat-generating member 80 by the fluctuating electromagnetic field of the heating unit 121. As a result, it is not necessary to have a configuration for generating a fluctuating electromagnetic field for the heat-generating member 80 separate from the heating unit 121.

Fourth Embodiment
FIG. 9 is a diagram showing a vertical cross section of a flavor inhalation stick 4 according to the fourth embodiment.
The stick 4 according to the fourth embodiment is different from the stick 3 according to the third embodiment in that the heated portion 410 corresponds to the heated portion 310. The differences from the third embodiment will be described below. The same reference numerals are used for the same parts in the third and fourth embodiments, and detailed descriptions thereof will be omitted.
In this embodiment, in the flavor inhaler 100 (see FIG. 2), the size and arrangement of the heating part 121 are appropriately changed so as to inductively heat at least a part of the heating member 70 in the heated part 410.

The heated portion 410 differs from the heated portion 310 according to the third embodiment (see FIG. 8 ) in that the accommodating portion 413 corresponding to the accommodating portion 313 is arranged on the second side (downstream side) of the base portion 411 corresponding to the base portion 311.
The heated portion 410 has 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 the capsule 50 and the 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 the tipping paper 40. The material constituting the wrapping paper 412 can be exemplified as being the same as the material constituting the wrapping paper 12 according to the first embodiment. Note that, when the heated portion 410 is made of two or more members such as the substrate portion 411, the storage portion 413, and the solid member 414, it is preferable that each of these two or more members is wrapped with a different wrapping paper before being wrapped together with the wrapping paper 412.

The substrate portion 411 is a portion that has the heat generating member 80 and includes a flavor source that generates an aerosol by heating. The substrate portion 411 is disposed on the first side (upstream side) of the storage portion 413. Specifically, the substrate portion 411 is disposed adjacent to an end surface of the storage portion 413 on the first side.
The cross-sectional area and centerline size of the base material portion 411, and the content of the flavor source may be appropriately changed according to the size of the stick 4. The flavor source contained in the base material portion 411 may be the same as the flavor source exemplified in the first embodiment.

The storage section 413 is a portion that has the heating member 70 and stores 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 end face on the second side of the base section 411, and is disposed such that the end face on the second side of the storage section 413 becomes the end face on the second side of the heated section 410. At least a portion of the storage section 413 is contained in the space 141 such that the heating member 70 is located within the varying electromagnetic field generated by the heating section 121 when the stick 4 is held by the holding section 140.
The material constituting the storage section 413 can be, for example, 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 of the circle and the perimeter of the cross section can be changed appropriately according to the size of the stick 4. 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 the circle is applied.

The solid member 414 is a member that prevents the capsule 50 and the heating member 70 from falling off from the end face on the first side of the heated portion 410 , and is disposed on the first side (upstream side) with respect to the base portion 411 .
The cross section of the solid member 414 is substantially circular, and the diameter of the circle and the circumference of the cross section can be appropriately changed according to the size of the stick 4. 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 constituting the solid member 414 is not particularly limited, but is preferably a material through which the contents 51 of the capsule 50 can permeate after passing through the base material 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.

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 broken by heat to release at least a flavor component, a heating member 70 for heating the capsule 50, and a storage section 413 for storing the capsule 50. From the viewpoint of compact size in the center line direction, the stick 4 does not need to include a cooling section 20 that cools the vapor and aerosol when the user inhales.
Like the stick 1, the stick 4 makes it easier to destroy capsules by heat compared to a configuration in which heating is performed from the outside of the stick 4.

In addition, the storage section 413 is preferably disposed adjacent to the downstream side of the base section 411 .
When the storage section 413 is disposed on the first side (upstream side) with respect to the substrate section 411, the capsule 50 is subjected to heat from the heating member 70, but the air passing through the storage section 413 is air flowing in from the end face of the first side of the stick 4. On the other hand, when the storage section 413 is disposed on the second side (downstream side) with respect to the substrate section 411, the capsule 50 is subjected to heat from the heating member 70, 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 end face of the first side of the stick 4. In this embodiment, the destruction efficiency of the capsule 50 can be improved by increasing the temperature of the heat applied to the capsule 50. In addition, when the capsule 50 is destroyed, the delivery efficiency of the flavor and aroma components contained in the contents 51 can be improved.

<Modification>
(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-mentioned embodiments. It is clear from the claims that various modifications or improvements to the above-mentioned embodiments are also included in the technical scope of the present disclosure.

(2) The heating member may be a member with high thermal conductivity. Here, it is assumed that a non-combustion heating type flavor inhaler heats the stick 1 from the outside. The flavor inhaler is equipped with a heater that generates heat when power is supplied, for example, and when this heater generates heat, the storage section included in the stick is heated from the outer periphery of the stick. If the heating member disposed in the storage section is a member with high thermal conductivity, heat generated by heating from the outer periphery is easily transmitted. 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 increasing due to heating from the outer periphery. When heating from the outside of the stick, it is possible to easily destroy the capsule compared to a configuration in which the storage section does not have a heating member with high thermal conductivity.
