Description

Flavor aspirator

The present invention relates to a flavor inhaler including a carbon heat source and a cylindrical member.

Conventionally, a flavor inhaler having a heat source having a columnar shape and a cylindrical member having a cylindrical shape is known. For example, one end portion of the tubular member constitutes a suction port, and the other end portion of the tubular member constitutes a support portion that supports the heat source.

Here, a technique using a carbon heat source containing 10 to 60 wt% carbon as a heat source has been proposed. A carbon heat source is arrange | positioned so that it may be exposed from a cylindrical member (for example, patent document 1).

Alternatively, it has been proposed to separate the heat source and the flavor source from the holder as a flavor inhaler that can repeatedly use the holder holding the heat source (for example, Patent Document 2).

In patent document 1 mentioned above, since the heat source is previously attached to the cylindrical member, the movement of the flavor component between the heat source and the member inside the cylindrical member (in this case, to the heat source of the component included in the flavor source) ) Occurs, and there is a concern about the deterioration of the flavor.

On the other hand, in Patent Document 2 described above, since the holder is repeatedly used, the structure of the holder is very complicated and the manufacturing cost of the holder is high. Therefore, the holder described in Patent Document 2 is not suitable for disposable use. In addition, since the heat source and the flavor source are separated from the holder, it is necessary to attach the heat source to the holder for storing the flavor source after the flavor source is attached to the holder, and such work is complicated for the user. .

The carbon heat source and the cylindrical member are disposable members. The carbon heat source is provided as a separate body from the cylindrical member that previously stores the flavor source. The said cylindrical member is comprised by the member which has flexibility rather than the said carbon heat source.

In the embodiment, the cylindrical member is a disposable member that stores a flavor source in advance. Therefore, since the user does not need to attach the flavor source to the cylindrical member, the user's work is reduced.

In the embodiment, the carbon heat source is provided as a separate body from the cylindrical member that previously stores the flavor source. Therefore, in the state before using a flavor suction device, the component contained in a flavor source does not transfer to a carbon heat source, but deterioration of flavor is suppressed.

[First Embodiment]
(package)
The package according to the first embodiment will be described below. FIG. 1 is a schematic diagram showing a package 100 according to the first embodiment.

As shown in FIG. 1, the package 100 includes an inner case 10 and an outer case 20.

The inner case 10 has a substantially rectangular parallelepiped outer shape defined by the width direction W, the longitudinal direction L, and the depth direction D. The inner case 10 has a bottom surface 11 defined by a width direction W and a longitudinal direction L. The inner case 10 has a box shape that opens toward the opposite side of the bottom surface 11. For example, the inner case 10 is configured by a flexible member (paper). Details of the inner case 10 will be described later (see FIG. 2).

The outer case 20 has a substantially rectangular parallelepiped outer shape defined by the width direction W, the longitudinal direction L, and the depth direction D. The outer case 20 has a cylindrical shape having a cavity 21 extending along the longitudinal direction L. The outer dimension of the inner case 10 described above is substantially the same as the inner dimension of the cavity 21, and the inner case 10 is accommodated in the cavity 21 of the outer case 20. For example, the outer case 20 is configured by a flexible member (paper). Of course, various materials such as resin and metal as well as flexible members (paper) can be used for the package.

(Inner case)
The inner case according to the first embodiment will be described below. FIG. 2 is a schematic diagram showing the inner case 10 according to the first embodiment.

As shown in FIG. 2, the inner case 10 has a partition portion 12 erected from the bottom surface 11. Specifically, the inner case 10 has a shape that stands up along the depth direction D. The partition part 12 partitions the space in the inner case 10 into a heat source housing space 10A (first space) for housing the carbon heat source and a cylindrical member housing space 10B (second space) for housing the tubular member.

The heat source housing space 10 A has a bottom surface 11 A on which a carbon heat source is to be placed. The bottom surface 11A is substantially parallel to a plane defined by the width direction W and the longitudinal direction L. The heat source housing space 10A has a heat source holding part 13A that holds a carbon heat source. 13 A of heat source holding parts hold | maintain a carbon heat source so that a predetermined direction may face in the direction (for example, perpendicular | vertical direction (depth direction D) with respect to the bottom face 11A) with respect to the bottom face 11A.

The predetermined direction is, for example, a direction from the non-insertion end portion of the carbon heat source toward the insertion end portion. The insertion end of the carbon heat source is an end inserted into the cylindrical member. Specifically, the heat source holding part 13A preferably holds the carbon heat source so that the direction from the non-insertion end of the carbon heat source toward the insertion end is directed in the direction from the bottom surface 11A toward the opening. Thus, the carbon heat source can be easily inserted into the cylindrical member while the carbon heat source is held by the heat source holding portion 13A.

As described above, in the case where the inner case 10, particularly the heat source holding part 13 A is configured by a flexible member (paper), the heat source holding part 13 A can easily arrange the heat source in the inner case 10, and carbon The heat source can be easily held, and the heat source can be easily inserted and removed from the cylindrical member.

The cylindrical member accommodation space 10 B has a bottom surface 11 B on which the cylindrical member is to be placed as the bottom surface 11. As will be described later, the bottom surface 11B may have an inclination with respect to a plane defined by the width direction W and the longitudinal direction L. The cylindrical member accommodation space 10B has a cylindrical member holding portion 13B that holds the cylindrical member. The cylindrical member holding portion 13 B holds the cylindrical member in a state where the cylindrical member is laid along the longitudinal direction L.

In the first embodiment, the carbon heat source and the cylindrical member constitute a flavor inhaler. Specifically, a flavor inhaler is formed by attaching a carbon heat source to a cylindrical member.

(Cylindrical member)
Below, the cylindrical member which concerns on 1st Embodiment is demonstrated. FIG. 3 is a schematic diagram showing the cylindrical member 30 according to the first embodiment.

As shown in FIG. 3, the cylindrical member 30 has a support end 30A and a suction side end 30B. The support end 30A is an end that holds the carbon heat source. The mouth end 30B is an end provided on the mouth side of the flavor inhaler. In 1st Embodiment, the inlet-side edge part 30B comprises the inlet of a flavor suction device. However, the suction port of the flavor suction device may be provided as a separate body from the cylindrical member 30.

The cylindrical member 30 has a cylindrical shape having a cavity 31 that extends along a direction from the support end 30A toward the inlet side end 30B. For example, the cylindrical member 30 has a cylindrical shape or a rectangular tube shape. The cylindrical member 30 accommodates the flavor source 32 in advance. The flavor source 32 is, for example, a powdered tobacco leaf or tobacco molded body used for cigarettes or snuff. Alternatively, the flavor source 32 is obtained by, for example, carrying various flavor components such as menthol on a porous material such as activated carbon or a non-porous material carrier.

Here, the cylindrical member 30 may accommodate a plurality of flavor sources in advance. In such a case, the plurality of flavor sources may be adjacent to each other or may be spaced apart. In addition to the flavor source 32, the tubular member 30 may previously contain a member such as a filter.

In the first embodiment, the cylindrical member 30 is a disposable member that stores the flavor source 32 in advance. The cylindrical member 30 is configured by a member that is more flexible than the carbon heat source. In other words, the members constituting the cylindrical member 30 are more flexible than the carbon heat source in the state of the cylindrical member 30. Here, flexibility means the ease of spreading of the cavity 31, that is, the ease of deformation of the tubular member 30 in the direction from the inside to the outside of the cavity 31. With such a configuration, even when a member such as the carbon heat source 50 that is not easily deformed is used as the heat source of the flavor inhaler, the user can easily attach the heat source to the cylindrical member 30.

The cylindrical member 30 is, for example, a paper tube made of at least one of a heat conductive member bonding paper and cardboard. The cylindrical member 30 may be one in which a heat conductive member is bonded to a part of a paper tube made of cardboard.

Furthermore, the cylindrical member 30 may have a single layer structure constituted by a single layer, or may have a multilayer structure constituted by a plurality of layers. Alternatively, the tubular member 30 may partially have a multilayer structure.

For example, the cylindrical member 30 is formed by winding a sheet-like member formed of at least one of a bonding paper and a cardboard of a heat conducting member into a cylindrical shape and bonding overlapping portions of the sheet-like member. Such a cylindrical member 30 may be a spiral wound paper tube or a flat wound paper tube. The spirally wound paper tube is a type of paper tube in which a thin paper is wound around a shaft called a mandrel in a spiral until a predetermined thickness is reached. The flat-wrapped paper tube is a type of paper tube in which rectangular (rectangular) paper is wound in a direction perpendicular to the mandrel axis.

The cardboard used for the cylindrical member 30 has a basis weight of 100 to 300 g / m 2, a thickness of 150 to 500 μm, and a density of 0.5 g / cm 3 or more, so that the cylindrical member is not greatly deformed by its own weight, It can be used suitably.

Thus, since the cylindrical member 30 is not assumed to be repeatedly used, the cylindrical member 30 is simply formed by winding a sheet-like member constituted by at least one of the bonding paper and the cardboard of the heat conducting member into a cylindrical shape. Paper tube. For example, the cavity 31 of the cylindrical member 30 has a uniform cross-sectional area in an orthogonal cross section orthogonal to a predetermined direction. Specifically, the body portions other than the support end portion 30A and the inlet side end portion 30B have a uniform cross-sectional area in the orthogonal cross section.

(Carbon heat source)
Hereinafter, the carbon heat source according to the first embodiment will be described. FIG. 4 is a schematic diagram showing the carbon heat source 50 according to the first embodiment.

As shown in FIG. 4, the carbon heat source 50 has a non-insertion end portion 50A and an insertion end portion 50B. The non-insertion end portion 50 A is an end portion exposed from the tubular member 30 in a state where the carbon heat source 50 is inserted into the tubular member 30. The insertion end portion 50 B is an end portion that is inserted into the cylindrical member 30.

The carbon heat source 50 has a columnar shape extending along a predetermined direction from the non-insertion end portion 50A toward the insertion end portion 50B. For example, the carbon heat source 50 has a cylindrical shape or a prismatic shape.

In the first embodiment, the carbon heat source 50 is provided as a separate body from the cylindrical member 30 that stores the flavor source 32 in advance. Specifically, as will be described later, the cylindrical member 30 and the carbon heat source 50 are separately accommodated in the state accommodated in the package 100 (see FIGS. 5 and 6).

The carbon heat source 50 is composed of a mixture containing a combustible substance. For example, the mixture containing a combustible substance includes a carbon material, an incombustible additive, a binder (an organic binder or an inorganic binder), and water. As the carbon material, it is preferable to use a material from which volatile impurities have been removed by heat treatment or the like.

The carbon heat source 50 preferably contains a carbonaceous material in the range of 10 wt% to 99 wt% when the weight of the carbon heat source 50 is 100 wt%. From the viewpoint of combustion characteristics such as supply of a sufficient amount of heat and ash tightening, the carbon heat source 50 preferably contains a carbonaceous material in the range of 30 wt% to 70 wt%, and the carbon quality in the range of 40 wt% to 50 wt%. More preferably, the material is included.

As the organic binder, for example, a mixture containing at least one of CMC (carboxymethylcellulose), alginate, EVA, PVA, PVAC and saccharide can be used.

As the inorganic binder, for example, a mineral type such as purified bentonite, or a silica type binder such as colloidal silica, water glass or calcium silicate can be used.

For example, from the viewpoint of flavor, the binder preferably contains 1% by weight to 10% by weight of CMC when the weight of the carbon heat source 50 is 100% by weight, and contains 1% by weight to 8% by weight of CMC. It is preferable.

As the incombustible additive, for example, carbonates or oxides made of sodium, potassium, calcium, magnesium, silicon, or the like can be used. The carbon heat source 50 may include 40% by weight to 89% by weight of an incombustible additive when the weight of the carbon heat source 50 is 100% by weight. Further, in the case of using calcium carbonate as an incombustible additive, the carbon heat source 50 preferably includes 40 to 55% by weight of an incombustible additive.

The carbon heat source 50 may contain an alkali metal salt such as sodium chloride at a ratio of 1 wt% or less when the weight of the carbon heat source 50 is 100 wt% for the purpose of improving combustion characteristics.

In the first embodiment, since the carbon heat source 50 is a combustion body, the non-insertion end portion 50A constitutes an ignition end portion. The carbon heat source 50 has a single cavity 51 extending along a predetermined direction from the non-insertion end portion 50A toward the insertion end portion 50B. The single cavity 51 can suppress fluctuations between the amount of heat supplied during suction (puffing) and the amount of heat supplied during non-suction (puffing), and can secure a stable amount of heat. The non-insertion end portion 50A and the insertion end portion 50B may have the same composition or shape, or may have different compositions or shapes. For example, the non-insertion end portion 50 A may have a notch 52 communicating with the cavity 51 so that the carbon heat source 50 can be easily ignited. Even when the non-insertion end portion 50A and the insertion end portion 50B have different compositions or shapes, the carbon heat source 50 is held in the heat source housing space 10A in a state in which the carbon heat source 50 faces in a predetermined direction in advance. Can be prevented from being inserted.

Here, the cavity 51 has a cross-sectional area in an orthogonal cross section orthogonal to the predetermined direction. The cross-sectional area of the cavity 51 is preferably 1.77 mm ² or more. The carbon heat source 50 is preferably formed with a single cavity 51, and the single cavity 51 is preferably disposed substantially at the center of the carbon heat source 50 in an orthogonal cross section.

In the first embodiment, the outer size of the carbon heat source 50 is substantially equal to the inner size of the cylindrical member 30 (cavity 31). Specifically, at least the outer dimensions of the body portion other than the non-insertion end portion 50A and the insertion end portion 50B are substantially equal to the inner dimension of the cylindrical member 30 (cavity 31), or the cylindrical member 30 (cavity 31). It is more than the inside dimension.

Here, the outer size of the body portion of the carbon heat source 50 is deformed in the circumferential direction without the tubular member 30 being cleaved or broken when the carbon heat source 50 is inserted into the tubular member 30. As long as the carbon heat source 50 can be held, it is preferably larger than the inner dimension of the cylindrical member 30 (cavity 31). For example, when a single-layer cardboard tube is adopted as the cylindrical member 30, the difference between the outer dimension of the body portion of the carbon heat source 50 and the inner dimension of the cylindrical member 30 (cavity 31) is less than 0.2 mm. It is preferable that the range be greater than 0.05 mm and less than or equal to 0.10 mm. With this configuration, when the user inserts the carbon heat source 50 into the cylindrical member 30, the carbon heat source 50 can be easily inserted and the carbon heat source 50 can be prevented from dropping off from the cylindrical member 30.

(Accommodated state of carbon heat source and cylindrical member)
Below, the accommodation state of the carbon heat source and cylindrical member which concern on 1st Embodiment is demonstrated. 5 and 6 are views showing the accommodation state of the carbon heat source 50 and the cylindrical member 30 according to the first embodiment.

As shown in FIGS. 5 and 6, the carbon heat source 50 is disposed in the heat source accommodation space 10 A partitioned by the partition portion 12. As described above, the carbon heat source 50 is held by the heat source holding unit 13A so that a predetermined direction is directed in a direction (for example, the depth direction D) intersecting the bottom surface 11A. Specifically, the carbon heat source 50 is held such that the insertion end 50B faces the opposite side of the bottom surface 11A.

Here, the heat source holding part 13A preferably has a structure for holding the carbon heat source 50 so that the insertion end part 50B protrudes from the upper end of the heat source holding part 13A. The length of the insertion end portion 50B of the carbon heat source 50 protruding from the upper end of the heat source holding portion 13A is preferably substantially equal to the length at which the insertion end portion 50B of the carbon heat source 50 should be inserted into the cylindrical member 30.

In the first embodiment, in the depth direction D, the height H ₁ of the carbon heat source 50 is greater than the height H ₂ of the heat source holding portion 13A. The difference P between the height H ₁ and the height H ₂ is substantially equal to the length at which the insertion end 50B should be inserted into the cylindrical member 30. The height H ₁ is the carbon heat source 50 in a predetermined direction toward the insertion end 50B from the non-insertion end portion 50A is long. The difference P is a length that the insertion end 50B protrudes from the upper end of the heat source holding part 13A.

As shown in FIGS. 5 and 6, the cylindrical member 30 is disposed in the cylindrical member accommodation space 10 B partitioned by the partition portion 12. As described above, the cylindrical member 30 is held by the cylindrical member holding portion 13B in a state where the cylindrical member 30 is laid down along the longitudinal direction L.

In the first embodiment, it is preferable that the bottom surface 11B has an inclination with respect to a plane defined by the width direction W and the longitudinal direction L, as will be described later. In the longitudinal direction L, the length of the tubular member holding portion 13 B is preferably shorter than the length of the tubular member 30. Thereby, the cylindrical member holding portion 13B can be easily taken out from the inner case 10.

(Function and effect)
In 1st Embodiment, the cylindrical member 30 is a disposable member which accommodates the flavor source 32 previously. Therefore, since the user does not need to attach the flavor source 32 to the tubular member 30, the user's work is reduced.

In the embodiment, the carbon heat source 50 is provided separately from the cylindrical member 30 that stores the flavor source 32 in advance. Therefore, the component contained in the flavor source 32 does not transfer to the carbon heat source 50 in a state before the use of the flavor inhaler, and deterioration of the flavor is suppressed.

[Modification 1]
Hereinafter, Modification Example 1 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.

In the first modification, as shown in FIG. 7, the insertion end 50B has a shape in which the outer dimension of the insertion end 50B is small from the non-insertion end 50A toward the insertion end 50B. The outer dimension of the insertion end 50B at the end of the insertion end 50B is smaller than the inner dimension of the support end 30A at the end of the support end 30A. However, the outer dimensions of the body portion other than the non-insertion end portion 50A and the insertion end portion 50B are substantially equal to the inner dimension of the cylindrical member 30 (support end portion 30A).

Thus, the insertion end 50B has a shape with a small outer dimension of the insertion end 50B from the non-insertion end 50A toward the insertion end 50B, so that the carbon heat source 50 can be easily inserted into the cylindrical member 30. . The insertion end portion 50B may have a tapered shape in which the outer dimension of the insertion end portion 50B gradually changes, or only the outer dimension of the end of the insertion end portion 50B may have a small shape. .

[Modification 2]
Hereinafter, Modification Example 2 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.

In the second modification, as shown in FIG. 8, the support end 30A has a shape in which the inner dimension of the support end 30A is small from the support end 30A toward the inlet side end 30B. The inner dimension of the support end 30A at the end of the support end 30A is larger than the outer dimension of the insertion end 50B at the end of the insertion end 50B. However, the inner dimension of the cylindrical member 30 in at least a part of a predetermined length (the length in which the carbon heat source 50 should be inserted) from the support end 30A of the cylindrical member 30 is the non-insertion end 50A and the insertion end. The outer dimensions of the body part other than the part 50B are substantially equal.

As described above, the support end portion 30A has a shape in which the inner dimension of the support end portion 30A is small from the support end portion 30A toward the inlet side end portion 30B, so that the carbon heat source 50 can be easily inserted into the cylindrical member 30. . The support end 30A may have a tapered shape in which the inner dimension of the support end 30A changes gradually, or may have a shape in which only the inner dimension of the end of the support end 30A is large. .

[Modification 3]
Hereinafter, Modification 3 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.

In the third modification, as shown in FIG. 9, the support end 30 A of the cylindrical member 30 is constituted by an outer cylindrical member 35 and an inner cylindrical member 36. The outer dimension of the insertion end 50B at the end of the insertion end 50B is substantially equal to the inner dimension of the outer cylindrical member 35 at the end of the outer cylindrical member 35. The inner cylindrical member 36 is provided inside the outer cylindrical member 35. Here, the length Q from the end of the outer cylindrical member 35 to the end of the inner cylindrical member 36 is preferably equal to the length at which the insertion end portion 50B of the carbon heat source 50 should be inserted into the outer cylindrical member 35. . With such a configuration, the inner cylindrical member 36 functions as a restricting portion that restricts the insertion of the carbon heat source 50, and thus does not depend on the length of the insertion end portion 50B of the carbon heat source 50 protruding from the upper end of the heat source holding portion 13A. The carbon heat source 50 can be inserted into the outer cylindrical member 35 with an appropriate insertion length. Further, the carbon heat source 50 can be inserted into the outer cylindrical member 35 with an appropriate insertion length without bringing the outer cylindrical member 35 and the heat source holding portion 13A into contact with each other at the time of insertion.

[Modification 4]
Hereinafter, Modification 4 of the first embodiment will be described. In the following, differences from the first embodiment will be mainly described.

Although not particularly mentioned in the first embodiment, in the fourth modification, as shown in FIG. 10, the flavor inhaler includes a heat conducting member 200 and a cup member 300 in addition to the tubular member 30 and the carbon heat source 50. Have.

The heat conducting member 200 is provided on the inner surface of the tubular member 30 at the support end 30 A of the tubular member 30. The heat conductive member 200 is preferably formed of a metal material having excellent heat conductivity, and is made of, for example, aluminum. In the predetermined direction, the length of the heat conducting member 200 is preferably at least longer than the length of the cup member 300. That is, the heat conductive member 200 protrudes from the cup member 300 to the suction side end 30B side. The length of the heat conductive member 200 may be the same as the length of the cylindrical member 30.

The cup member 300 has a cup shape, houses the flavor source 32 (here, the flavor source), and holds the carbon heat source 50. The cup member 300 is configured to be inserted into the support end 30 A of the cylindrical member 30. Specifically, the cup member 300 includes a cylindrical side wall 310 and a bottom plate 320 that closes one opening formed by the side wall 310. The flavor source 32 (here, flavor source) and the carbon heat source 50 are inserted into the cup member 300 from one opening formed by the side wall 310. The bottom plate 320 has a plurality of vent holes 320A for allowing air to pass therethrough.

Here, the flavor source 32 (here, the flavor source) is composed of, for example, powdered tobacco leaves. In such a case, the size of the vent hole 320A is smaller than the particle size of the tobacco leaf.

In the fourth modification, the thickness of the side wall 310 is preferably 0.1 mm or less. Thereby, the heat capacity of the side wall 310 is reduced, and the heat generated by the carbon heat source 50 is efficiently transmitted to the flavor source. Moreover, it is preferable that the side wall 310 is comprised by SUS (for example, SUS430). Thereby, even if the thickness of the side wall 310 is 0.1 mm or less, sufficient strength is obtained as the strength of the side wall 310, and the shape of the cup member 300 is maintained. In addition, it is preferable that the baseplate 320 is comprised with the same member (for example, SUS430) as the side wall 310. FIG.

Although not specifically mentioned in the embodiment, the dimensions of the package 100 in the depth direction D are preferably smaller than the dimensions of the package 100 in the longitudinal direction L and the width direction W. However, the embodiment is not limited to this.

Although not specifically mentioned in the embodiment, the dimension of the package 100 in the longitudinal direction L is preferably smaller than the dimension of the package 100 in the width direction W. However, the embodiment is not limited to this.

In the embodiment, in the depth direction D, the height H ₁ of the carbon heat source 50 is larger than the height H ₂ of the heat source holding unit 13A. However, the embodiment is not limited to this. The heat source holding part 13A only needs to have a structure for holding the carbon heat source 50 so that the insertion end part 50B protrudes from the upper end of the heat source holding part 13A. Therefore, the inner case 10 may have a structure in which the bottom surface 11 A rises along the depth direction D in conjunction with the operation of pulling out the inner case 10 from the outer case 20. In such a case, by pulling out the inner case 10 from the outer case 20, the heat source holding part 13A holds the carbon heat source 50 so that the insertion end part 50B protrudes from the upper end of the heat source holding part 13A.

In the embodiment, the case where the carbon heat source 50 is placed on the bottom surface 11 has been described, but the embodiment is not limited thereto. For example, a space may be provided between the bottom surface 11 and the carbon heat source 50, and the carbon heat source 50 may be supported only by the heat source holding part 13A.

In the embodiment, the case where the carbon heat source 50 has a single cavity 51 extending along a predetermined direction from the non-insertion end portion 50A toward the insertion end portion 50B has been described, but the embodiment is not limited thereto. . For example, the carbon heat source 50 may have a plurality of cavities extending along a predetermined direction from the non-insertion end portion 50A toward the insertion end portion 50B, or may not have such a cavity. Moreover, the shape of the cavity can be arbitrarily changed.

Although embodiment demonstrated the case where the cylindrical member 30 of a flavor suction device is a paper tube comprised by at least one of the bonding paper and cardboard of a heat conductive member, embodiment is limited to this. is not. For example, as the cylindrical member 30, in order to impart flame resistance, a cellulose pulp made by adding magnesium hydroxide or aluminum hydroxide may be used, and further, coated with calcium carbonate, polyvinyl alcohol, or the like. Thus, a sheet having a multilayer structure may be used.

In the embodiment, the case where the heat source of the flavor inhaler is a carbon heat source has been described. However, the embodiment is not limited thereto, and any material that releases or sorbs volatile components is preferably employed. can do. For example, instead of the carbon heat source 50, a molded body obtained by molding a mixture containing tobacco powder particles by a technique such as extrusion, tableting, or injection molding may be employed. In such a case, since the tobacco molded product also serves as a flavor source, the arrangement of the flavor source 32 inside the tubular member 30 can be made arbitrary. Even in such a case, by providing the tobacco molded body as a separate member from the tubular member, the tobacco molded body and the tubular member 30 or the tubular member 30 are accommodated in the state before the use of the flavor inhaler. The movement of the component between the members (in this case, the movement of the component contained in the tobacco molded product to the cylindrical member or the member accommodated in the cylindrical member) can be suppressed, and the flavor is deteriorated. Can be suppressed.

Note that the entire content of Japanese Patent Application No. 2013-47284 (filed on March 8, 2013) is incorporated herein by reference.

According to the present invention, it is possible to provide a flavor inhaler capable of reducing the work of the user and suppressing the deterioration of the flavor.
