Since the support element (support) described in Patent Document 1 is composed of a hollow cylindrical member having a flow path formed in the central portion, there is a problem that the structure is complicated and the manufacturing cost is high. Further, in Patent Document 1, since the outer peripheral portion (thick portion) of the support element is in contact with the aerosol forming base material, there is also a problem that the amount of aerosol generated and the flow become uneven.

The present invention has been made in view of such circumstances, and an object of the present invention is to provide a cartridge for smoking equipment in which the structure of a support is simplified while suppressing the amount of aerosol generated and uneven flow. be.

In order to achieve the above object, one aspect of the present invention includes an aerosol-forming substrate made from a tobacco plant or a non-tobacco plant, a mouthpiece arranged coaxially with the aerosol-forming substrate, and the aerosol forming. A cigarette cartridge comprising a support disposed between the base material and the mouthpiece to support the aerosol-forming base material, wherein the support is formed by winding a sheet-like member. The shaft-shaped member is composed of a shaft-shaped member, the axial direction of the shaft-shaped member is arranged along the central axis of the cigarette cartridge, and the aerosol produced by heating the aerosol-forming base material is the aerosol. It is characterized in that it is formed so as to be able to pass through the inside of the shaft-shaped member.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(First Embodiment)
FIG. 1 is a cross-sectional view of a cartridge 1 for smoking equipment according to the first embodiment of the present invention. As shown in FIG. 1, the smoking equipment cartridge 1 according to the first embodiment includes a heated body 20, a support 30, and a mouthpiece 40. The heated body 20, the support 30, and the mouthpiece 40 are arranged side by side on the central axis C1. The heated body 20, the support 30, and the mouthpiece 40 are wound and integrated by a sheet-shaped exterior member 10. The exterior member 10 is made of, for example, paper.

Here, the smoking equipment cartridge 1 shown in FIG. 1 is formed, for example, having a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. Further, the heated body 20 has a length of 10 to 25 mm. Of course, the cartridge 1 for smoking equipment may be formed with other dimensions.

The body 20 to be heated is formed by winding an aerosol-forming base material 23, which is a filling material, around a sheet-shaped packaging member 25 to form a cylindrical shape, and the aerosol-forming base material 23 is exposed at both ends thereof. That is, both ends of the heated body 20 are not covered with a lid member (for example, paper). The packaging member 25 is made of, for example, paper, but any material may be used as long as it is a sheet-shaped member. The packaging member 25 may be omitted by directly winding the aerosol-forming base material 23 around the exterior member 10, or the aerosol-forming base material 23 may be covered with a lid member.

The aerosol-forming base material 23 is composed of a smoking material made from a tobacco plant or a non-tobacco plant, which will be described in detail later. The aerosol-forming base material 23 is, for example, configured by bundling strip-shaped members, and is arranged so that its axial direction (longitudinal direction) is along the central axis C1.

When the aerosol forming base material 23 is composed of a strip-shaped member, the cross section orthogonal to the central axis C1 is substantially rectangular, and the ratio of the long side to the short side of the cross section is, for example, 1.5: 1 to 30 :. It is preferably in the range of 1. Further, it is preferable that the length of the aerosol-forming base material 23 is substantially the same as the length of the object to be heated 20. To give an example of the dimensions of the aerosol-forming base material 23, the long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

Of course, the aerosol-forming base material 23 is not limited to the strip-shaped member. For example, it may be a rod-shaped member, or may be a powder-grained or paste-shaped member. Further, the aerosol forming base material 23 is a combination of a strip-shaped member and a powder-granular member, a combination of a strip-shaped member and a rod-shaped member, a combination of a rod-shaped member and a powder-granular member, or a strip-shaped member. It may be configured by a combination of a rod-shaped member and an aerosolized member. In these cases, it is preferable that at least a part of the raw materials of each member is different because the aroma and taste are improved.

The mouthpiece 40 is a portion constituting the mouthpiece of the cartridge 1 for smoking equipment, and is formed by using, for example, paper or the like. Further, the mouthpiece 40 may include a cellulose acetate filter or the like for removing fine particles. A part of the water vapor generated by the heated body 20 and the fine particles in the aerosol is filtered by the filter of the mouthpiece 40.

The support 30 is composed of one shaft-shaped member 31 formed in a cylindrical shape by winding a thin sheet-shaped member (for example, paper, polymer sheet, rubber sheet, metal sheet, etc.). The axial member 31 is arranged so that its axial direction (longitudinal direction) is along the central axis C1 of the smoking equipment cartridge 1. Then, one end of the shaft-shaped member 31 comes into contact with the aerosol-forming base material 23, and the other end comes into contact with the mouthpiece 40, whereby the movement of the aerosol-forming base material 23 in the axial direction is restricted. In other words, the aerosol-forming substrate 23 is prevented from falling off from the heated body 20.

In the present embodiment, the diameter of the shaft-shaped member 31 is smaller than the diameter of the heated body 20, and is about 2/3. An annular space S1 is formed between the outer peripheral surface of the shaft-shaped member 31 and the exterior member 10. This space S1 constitutes a flow path through which the aerosol flows. The diameter of the shaft-shaped member 100 is arbitrary, and may be substantially equal to the diameter of the heated body 20. In this case, the space S1 is hardly formed. Further, the shaft-shaped member 100 may be arranged so as to be substantially along the central axis C1 of the smoking equipment cartridge 1, and may be arranged in a slightly tilted state.

FIG. 2 is a cross-sectional view taken along the line II-II of FIG. 1, and FIG. 3 is a perspective view of the support 30 (axial member 31). As shown in FIGS. 2 and 3, the shaft-shaped member 31 is formed by spirally winding a sheet-shaped member in multiple layers, and is formed so that an aerosol can pass through the inside thereof. Specifically, in the cross section orthogonal to the axial direction of the axial member 31, the spirally formed flow path 35 is uniformly formed along the axial direction of the axial member 31. The aerosol reaches the mouthpiece 40 while being cooled in the process of flowing through the flow path 35.

Further, the width W of the flow path 35 is such a size that the aerosol forming base material 23 cannot pass through. This prevents the aerosol-forming substrate 23 from being clogged in the flow path 35. For example, when the aerosol-forming base material 23 is formed in powder particles, the width W of the flow path 35 may be smaller than the average particle diameter of the aerosol-forming base material 23. When the aerosol-forming base material 23 is formed in a strip shape or a rod shape, the width W of the flow path 35 may be smaller than the long side of the cross section of the aerosol-forming base material 23.

Next, a specific example of the raw material used as the aerosol forming base material 23 will be described. The aerosol-forming substrate 23 is composed of any one or a plurality of combinations of the raw materials shown below.

The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant. Examples of tobacco plants include tobacco leaves, tobacco stems, swollen tobacco, homogenized tobacco and the like. Examples of non-tobacco plants include plants other than tobacco plants.

The aerosol-forming substrate 23 is appropriately provided with, for example, an aerosol former that generates an aerosol, microcrystalline cellulose, an additive that adds a flavor, a preservative, a binder, a thickener, or the like, to a dried / crushed non-tobacco plant. It is mixed, crushed or classified into powder or granules, or formed into a paste. Further, the aerosol-forming base material 23 is formed into a sheet shape and then cut into a strip shape or a rod shape so as to have a predetermined width and length.

For example, if the part of the non-tobacco plant is a leaf, tea can preferably be used. Not only are the plants that make tea different, but even the same plants are different depending on the processing method. Specifically, for example, Japanese tea, tea, tomorrow's leaf tea, sweet tea, Amachazuru tea, aloe tea, ginkgo leaf tea, oolong tea, corn tea, urajirogashi tea, eleuthero tea, obaco tea, kakiodoshi tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara deceased tea, karin tea, chrysanthemum tea, gymnema tea, guaba tea, kuko tea, soft leaf tea, black soybean tea, gennoshoko tea, brown rice tea, gobo tea, comfrey tea, bifu tea , Sakura tea, Saffron tea, Shiitake tea, Shiso tea, Jasmine tea, Ginger tea, Sugina tea, Sekisho tea, Senburi tea, Soba tea, Taranoki tea, Dandelion tea, Jin tea, Dokudami tea, Tochu tea, Natamame tea, Niwatoko tea , Mouse mochi tea, Hatomugi tea, Hub tea, Biwa leaf tea, Poor tea, Benihana tea, Matsuba tea, Mate tea, Wheat tea, Megusurinoki tea, Yomogi tea, Eucalyptus tea, Rakan fruit tea, Louis Bosti, Goya tea and the like.

The microcrystalline cellulose as a raw material of the aerosol-forming base material 23 is, for example, obtained by partially depolymerizing α-cellulose obtained from the pulp of a fibrous plant with an acid, and is a soluble portion from the cellulose. Is removed, and the insoluble portion is appropriately crystallized.

The microcrystalline cellulose may be a powder as it is, or may be dispersed in a solvent such as water and used as a candlepower solution. In this case, a high-speed stirrer, a high-pressure homogenizer, or the like can be used for dispersion in the solvent.

Further, if necessary, a flavor additive that adds flavor as a raw material for the aerosol-forming substrate 23 is also preferably used. Examples of the flavor additive include hakka, cocoa, coffee, black tea extract, catechin powder of tea extract and the like. As the preservative, those used in foods are preferable, and examples thereof include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate and the like.

The aerosol-forming substrate 23 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to those obtained from natural products, but may be synthetic products. It may also contain peppermint, mint, peppermint oil and other menthol.

The flavor additive is provided on the mouthpiece 40, for example, by impregnating the wall portion of the mouthpiece 40. The mode in which the flavor additive is provided in the mouthpiece 40 is not limited to such a mode. For example, the mouthpiece is formed by embedding a capsule containing the flavor additive in the wall portion of the mouthpiece 40. A flavor additive may be provided in 40. Alternatively, a capsule containing a flavor additive may be arranged between the mouthpiece 40 and the heated body 20. When the flavor additive is encapsulated, the smoker can break the capsule by pressing the capsule with a finger, allowing the aromatic component of the flavor additive to be volatilized at the desired timing. Become.

Further, when the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided in the heated body 20. Of course, the microcapsule (capsule 60) may be provided on the support 30 (see FIG. 7B).

(Manufacturing method of aerosol forming base material)
The method for producing the aerosol-forming substrate 23 described above will be described separately for each step. The manufacturing process of the aerosol forming base material 23 includes a drying / crushing step of drying / crushing a tobacco plant or a non-tobacco plant as a main raw material and weighing them, and a pretreatment step of performing pretreatment and weighing of other raw materials. It has a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition.

In the drying / crushing step, since the part of the tobacco plant or non-tobacco plant used as the main raw material (for example, leaves, seeds, dried fruits, stems, bark, roots, etc.) is used as a composition, it is processed into a predetermined crushed product. .. At that time, it is preferable to adjust the amount of water to be convenient for absorbing or supporting the aerosol former, water and other components to be added later. In drying, the temperature is preferably 60 ° C. or higher and 80 ° C. or lower. Within this range, it is easy to reach the desired water content while avoiding the dissipation of the required flavor component. Further, the drying / crushing step may be provided with a sieving step for sieving the crushed product, and the pulverized product can be adjusted to a desired particle size and put into the mixing step.

In the preparation step, the raw materials necessary for producing the aerosol-forming base material 23 can be prepared. The microcrystalline cellulose described above is weighed in the preparatory step and charged into the mixing step.

In the mixing step, a normal mixer can be used. For example, a form in which the raw materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used.

In the filler forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form a strip-shaped or rod-shaped aerosol-forming base material 23. In this embodiment, a plurality of roll mills are prepared in order to make a thin sheet. By using multiple roll mills, it is possible to obtain a sheet of the desired thickness by the doctor blade while performing kneading, dispersion, etc. by compression by being pushed between narrow rolls and shearing by the difference in roll speed. ,preferable. It can also be manufactured using a press roller or a press machine.

Further, in order to obtain a powdery or granular aerosol-forming substrate 23, it is preferable to appropriately grind or classify the above composition. The average particle size of the powdery or granular aerosol-forming substrate 23 is preferably, for example, 0.1 to 3.0 mm, more preferably 0.5 mm or less. The average particle size is determined by, for example, the sieving method described in JIS K 0069: 1992. That is, this average particle diameter refers to a diameter corresponding to 50% of the mass obtained by integrating the masses of the test results using a plurality of sieves from the one having the largest opening. Further, the particle size at an integrated value of 50% in the particle size distribution obtained by the laser diffraction / scattering method may be used as the average particle size.

In the filling molding step, other means such as molding the composition by passing it through an orifice by pressurization may be used. Further, in the filling molding step, if necessary, flavor additives and preservatives such as non-tobacco plants, aerosol formers, binders or thickeners may be further added, or water or the like may be added. Is also good.

The thickness of the sheet obtained in the filler molding step is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut to a predetermined width by a cutter, a rotary blade type rotary cutter, or the like.

Here, the case of imparting adhesiveness to the surface of the aerosol-forming base material 23 is not particularly limited as long as it is a means capable of imparting adhesiveness, but the above-mentioned binder may be attached to at least a part thereof. By imparting adhesiveness, when the strip-shaped or rod-shaped aerosol-forming base material 23 is combined with the powder-like, granular or paste-like aerosol-forming base material 23, the surface of the strip-shaped or rod-shaped aerosol-forming base material 23 The powdery, granular or paste-like aerosol-forming substrate 23 can be stably held.

(How to use the cartridge for smoking equipment)
The method of using the cartridge 1 for smoking equipment will be described. FIG. 4 is a cross-sectional view showing a state in which the smoking tool cartridge 1 is inserted into the smoking tool 70. The smoking tool cartridge 1 is attached to the heated smoking tool 70 and used. The smoking tool 70 has an insertion portion 72 for inserting the smoking tool cartridge 1. The insertion portion 72 is provided with a needle-shaped or blade-shaped heating portion 75. When the heating unit 75 generates heat with the smoking equipment cartridge 1 inserted in the insertion unit 72, an aerosol is generated from the aerosol forming base material 23. When the smoker holds the mouthpiece 40 and sucks it in this state, the aerosol flows in the order of the support 30 (flow path 35 and the space S1) and the mouthpiece 40, and flows into the smoker's mouth.

According to the smoking equipment cartridge 1 according to the first embodiment configured in this way, the following effects can be obtained.

Since the support 30 is composed of a shaft-shaped member 100 in which a thin sheet-shaped member is spirally wound, the structure of the support 30 is simple and the manufacturing cost can be reduced. Further, since the shaft-shaped member 100 has a structure in which a sheet-shaped member is wound in a spiral shape and a spiral flow path 35 is formed inside, the shaft-shaped member 100 is thick as in the above-mentioned prior art (Patent Document 1). Does not have a large outer peripheral part. Therefore, the end portion (one side of the sheet-shaped member) of the shaft-shaped member 100 is dispersed and abuts on the end surface of the aerosol-forming base material 23. In other words, unlike the above-mentioned prior art, the outer peripheral portion of the support element does not locally abut on the end portion of the aerosol-forming substrate. Therefore, the amount of aerosol generated by heating the aerosol-forming base material 23 and the unevenness of the flow are suppressed. As a result, the aroma and taste of the aerosol are improved. Further, the aerosol is effectively cooled by passing through the space S1 and the spiral flow path 35. In particular, since the support 30 has a structure in which a sheet-shaped member is wound, the contact area between the aerosol and the sheet-shaped member is large when the aerosol passes through the flow path 35. Therefore, the heat of the aerosol is exchanged with the sheet-shaped member, and the aerosol is effectively cooled. As a result, the smoker's aerosol sucking comfort is improved.

Further, since the support 30 is interposed between the aerosol-forming base material 23 and the mouthpiece 40 to restrict the axial movement of the aerosol-forming base material 23, the smoking tool cartridge 1 is used as the smoking tool 70. The position of the aerosol-forming base material 23 is prevented from being displaced during insertion. Therefore, the heating of the aerosol-forming base material 23 by the heating unit 75 is stable, and a good aerosol is generated. Further, by providing the support 30, it is possible to prevent deformation in the axial direction when the smoking tool cartridge 1 is inserted into the smoking tool 70.

When the diameter of the support 30 is substantially equal to the diameter of the heated body 20, the exterior member 10 is supported by the outer peripheral surface of the support 30, and therefore the deformation in the radial direction when the smoking equipment cartridge 1 is grasped by a finger. Can also be prevented.

Next, a modification of the smoking equipment cartridge 1 according to the first embodiment will be described.

(Modification 1-1)
FIG. 5 is a cross-sectional view of the support 30-1 according to the modified example 1-1. Note that FIG. 5 is a cross-sectional view cut at the same position as the line II-II in FIG. The shaft-shaped member 31-1 shown in FIG. 5 is formed by winding a sheet-shaped member in a spiral shape to form a square cylinder, and its cross-sectional outer shape is substantially rectangular. Then, in the cross section shown in FIG. 5, a spiral flow path 35-1 is formed.

Even with such a configuration, the same effect as that of the first embodiment described above can be obtained. The outer shape of the cross section may be a square or a polygon such as a pentagon or a hexagon.

(Modification 1-2)
FIG. 6 is a cross-sectional view of the support 30-2 according to the modified example 1-2. Note that FIG. 6 is a cross-sectional view taken at the same position as the line II-II in FIG. The shaft-shaped member 31-2 shown in FIG. 6 is formed by winding a sheet-shaped member in a spiral shape to form a triangular cylinder, and its cross-sectional outer shape is a substantially equilateral triangle. Then, in the cross section shown in FIG. 6, a spiral flow path 35-2 is formed.

Even with such a configuration, the same effect as that of the first embodiment described above can be obtained. The outer shape of the cross section may be an isosceles triangle, a right triangle, or the like.

(Modification 1-3)
FIG. 7A is a diagram showing a state before completion of the support 30-3 according to the modified example 1-3, and FIG. 7B is a perspective view (after completion) of the support 30-3 according to the modified example 1-3. In this example, as shown in FIG. 7A, a sheet-shaped member formed in a trapezoidal shape is prepared by cutting the portion of the two-dot chain line among the rectangular sheet-shaped members. Then, when this trapezoidal member is wound around the short side in the direction of the arrow in the drawing, a conical recess 37 is formed as shown in FIG. 7B.

Then, as shown in FIG. 7B, the support 30-3 according to the modified example 1-3 is provided with a capsule 60 in the recess 37 formed at the end thereof. The capsule 60 changes the aroma and taste with respect to the aerosol, and the above-mentioned various flavor additives can be used.

According to this modification 1-3, since the aerosol is flavored by the capsule 60, the aroma and taste can be improved. Further, by crushing or chewing the capsule 60 by hand, a deeper taste can be realized. Further, since the capsule 60 is provided inside the support 30-3, it is difficult for the impact to be transmitted to the capsule 60 even if vibration or impact is applied to the cartridge for smoking equipment. As a result, the capsule 60 is prevented from being torn and the flavor is prevented from flying. Further, since the capsule 60 is provided at a position substantially along the central axis C, when the capsule 60 is crushed, the flavor additive spreads uniformly inside the support 30-3 and is uniformly mixed with the aerosol. Therefore, it has a deeper taste.

(Second Embodiment)
Next, the smoking equipment cartridge 2 according to the second embodiment of the present invention will be described. The smoking equipment cartridge 2 according to the second embodiment has basically the same configuration as the smoking equipment cartridge 1 according to the first embodiment, but the configuration of the support is different. Therefore, in the following description, this difference will be mainly described, and the description overlapping with the first embodiment will be omitted.

FIG. 8 is a cross-sectional view of the smoking equipment cartridge 2 according to the second embodiment of the present invention, and FIG. 9 is a perspective view of the support 130 shown in FIG. As shown in FIG. 8, the smoking equipment cartridge 2 according to the second embodiment includes a heated body 20, a support 130, and a mouthpiece 40.

As shown in FIG. 9, the support 130 is a single axial member 131 formed by spirally winding a thin sheet-like member (for example, paper, polymer sheet, rubber sheet, metal sheet, etc.) into a cylindrical shape. Consists of. Inside the shaft-shaped member 131, a flow path 135 through which an aerosol flows is formed in a spiral shape. The shaft-shaped member 131 is configured such that the end portion 132 thereof is stretched in the axial direction (longitudinal direction) so that the diameter is reduced toward the tip end side. As a result, the shaft-shaped member 131 has some elasticity in the axial direction. When the shaft-shaped member 131 is arranged so that its axial direction is along the central axis C1 of the smoking equipment cartridge 1, one end of the shaft-shaped member 131 abuts so as to slightly press the aerosol-forming base material 23, and the other end 132. Touches the mouthpiece 40 so as to slightly press it. In this way, the axial movement of the aerosol-forming substrate 23 is restricted.

According to this configuration, in addition to exhibiting the same action and effect as in the first embodiment, since the axial member 131 has elasticity in the axial direction, the support of the aerosol-forming base material 23 becomes even better. Further, when the smoking tool cartridge 2 is inserted into the smoking tool 70, the aerosol forming base material 23 may be pressed by the heating portion 75 and pushed out to the inside. The extruded aerosol-forming substrate 23 will press the axial member 131 in the axial direction. However, according to the present embodiment, since the end surface of the shaft-shaped member 131 facing the aerosol forming base material 23 is recessed and has elasticity in the axial direction, it responds to the pressing by the aerosol forming base material 23. Then, the central part of the end face is displaced so as to escape inward. As a result, the smoking tool cartridge 2 can be smoothly inserted into the smoking tool 70.

Next, a modified example of the smoking equipment cartridge 2 according to the second embodiment will be described.

(Modification 2-1)
FIG. 10 is a perspective view of the support 130-1 according to the modified example 2-1. The shaft-shaped member 131-1 shown in FIG. 10 spirals a flexible sheet-shaped member (for example, a thermoplastic resin such as PPS (polyphenylene sulfide) or a thermosetting resin such as PI (polyimide)). It is formed by rolling it into a shape. Then, a flow path 135-1 through which the aerosol flows is formed inside the shaft-shaped member 131-1.

Even with such a configuration, since the elastic force can be applied in the axial direction of the support 130-1, the same action and effect as those of the second embodiment described above can be obtained.

(Modification 2-2)
FIG. 11 is a cross-sectional view of a smoking equipment cartridge 2 including the support 132-2 according to the modified example 2-2, and FIG. 12 is a smoked equipment showing a state in which the support 132-2 according to the modified example 2-2 is displaced. It is sectional drawing of the cartridge 2.

As shown in FIG. 11, the support 132-2 according to the modified example 2-2 is composed of one axial member 131-2 formed in a cylindrical shape by spirally winding a thin sheet-shaped member. Inside the shaft-shaped member 131-2, a flow path 135-2 through which an aerosol flows is formed in a spiral shape. Then, when one end of the shaft-shaped member 131-2 is pushed in the axial direction, the central portion of one end surface is recessed and the end portion on the other end side is stretched as shown in FIG. Then, when the external force applied in the axial direction is released, the shaft-shaped member 131-2 returns to its original shape. That is, the shaft-shaped member 131-1 is configured to be elastically deformable in the axial direction.

This configuration itself is the same as that of the shaft-shaped member 31 shown in FIG. 1, but the axial length of the shaft-shaped member 131-2 is shorter than that of the shaft-shaped member 31. Therefore, a space S1 is formed between the shaft-shaped member 131-2 and the mouthpiece 40. Further, the outer peripheral surface of the shaft-shaped member 131-2 is in contact with the inner peripheral surface of the exterior member 10. That is, the diameter of the support 130-2 and the diameter of the exterior member 10 are configured to be substantially equal to each other.

According to this configuration, the same effect as that of the second embodiment described above is obtained. Further, the outer peripheral surface of the shaft-shaped member 131-2 suppresses the radial deformation of the exterior member 10.

Further, when the smoking tool cartridge 2 is inserted into the smoking tool 70, even if the aerosol forming base material 23 is pressed by the heating portion 75 and pushed out to the inside, as shown in FIG. 12, the shaft-shaped member 131 Since the central portion of -2 is displaced so as to be recessed in the axial direction (dotted line in the figure), the smoking tool cartridge 2 can be smoothly inserted into the smoking tool 70.

(Third Embodiment)
Next, the smoking equipment cartridge 3 according to the third embodiment of the present invention will be described. The smoking equipment cartridge 3 according to the third embodiment has basically the same configuration as the smoking equipment cartridge 1 according to the first embodiment, but the number of supports is mainly different. Therefore, in the following description, this difference will be mainly described, and the description overlapping with the first embodiment will be omitted.

FIG. 13 is a cross-sectional view of a support 230 used in the smoking equipment cartridge 3 according to the third embodiment of the present invention. Note that FIG. 13 is a cross-sectional view taken at the same position as the line II-II in FIG. As shown in FIG. 13, in the present embodiment, the support 230 is composed of two shaft-shaped members 231. The shaft-shaped member 231 is configured in the same manner as the shaft-shaped member 31 according to the first embodiment. That is, the shaft-shaped member 231 is formed by spirally winding a thin sheet-shaped member in a cylindrical shape, and the flow path 235 through which the aerosol flows is formed in a spiral shape. The two shaft-shaped members 231 are bundled together by the sheet-shaped binding member 15. The binding member 15 is made of, for example, paper, but a rubber member, a film sheet, or the like may be used.

According to this configuration, the same action and effect as those of the first embodiment are obtained. Further, since the two shaft-shaped members 231 are bundled and integrated by the binding member 15, the support 230 is easy to handle. Therefore, the work of winding the heated body 20, the support 230, and the mouthpiece 40 with the exterior member 10 becomes easy. Further, since the support 230 is formed by the two shaft-shaped members 231, the rigidity of the support 230 is increased, and the axial deformation of the smoking equipment cartridge 3 can be further prevented. The number of shaft-shaped members 231 is not limited to two, and may be three or more.

Next, a modification of the smoking equipment cartridge 3 according to the third embodiment will be described.

(Modification 3-1)
FIG. 14 is a cross-sectional view of the support 230-1 according to the modified example 3-1. It should be noted that FIG. 14 is a cross-sectional view cut at the same position as the line II-II in FIG. The support 230-1 shown in FIG. 14 has a configuration in which two shaft-shaped members 231 and 232 are bundled by a binding member 15 and integrated, but the shaft-shaped member 231 and the shaft-shaped member 232 have a shaft. The cross-sectional shape (outer shape) orthogonal to the direction (longitudinal direction) is different. Specifically, the shaft-shaped member 231 has a substantially round cross-sectional outer shape (see FIG. 2), whereas the shaft-shaped member 232 has a substantially triangular cross-sectional outer shape (see FIG. 6). Even if it is configured in this way, it has the same effect as that of the third embodiment. The cross-sectional outer shapes of the shaft-shaped member 231 and the shaft-shaped member 232 may be different from each other, and are not limited to the combination of the round shape and the triangular shape shown in FIG.

(Modification 3-2)
FIG. 15 is a cross-sectional view of the support 230-2 according to the modified example 3-2. It should be noted that FIG. 15 is a cross-sectional view cut at the same position as the line II-II in FIG. The support 230-2 shown in FIG. 15 is consistent with the third embodiment in that it includes two shaft-shaped members 231 but the configuration for bundling the two shaft-shaped members 231 is different. Specifically, in this example, one shaft-shaped member 231 (left-side shaft-shaped member) is wrapped with a binding portion 231a that is a part of the other shaft-shaped member 231 (right-side shaft-shaped member), and the other shaft. The two shaft-shaped members 231 are bundled by adhering the end portion 231b of the binding portion 231a to the outer peripheral surface of the shaped member 231. Even with this configuration, the same action and effect as those of the third embodiment can be obtained. Further, in this example, since the binding member 15 is unnecessary, there is an advantage that the number of parts can be reduced.

Here, in this example, the configuration in which one shaft-shaped member 231 is wrapped by the binding portion 231a of the other shaft-shaped member and bundled has been described, but one sheet-shaped member is spirally wound from both ends and two. It is also possible to form a shaft-shaped member. Even with this configuration, since the two shaft-shaped members are integrated without using the binding member 15, handling is easy and the number of parts can be reduced.

The present invention is not limited to the above embodiment, and various modifications can be made without departing from the gist of the present invention, and all of the technical matters included in the technical idea described in the claims are the present invention. It is the subject of the invention. Although the above embodiment shows a suitable example, those skilled in the art can realize various alternative examples, modified examples, modified examples, or improved examples from the contents disclosed in the present specification. These are included in the technical scope set forth in the appended claims.

For example, as the sheet-shaped member constituting the shaft-shaped member 31, 131,231, any material such as paper, a polymer sheet, a rubber sheet, a metal sheet, and a resin sheet can be used as described above, but the aerosol can be used. If you want to enhance the cooling effect, it is better to use a metal sheet. Further, when a shape memory alloy is used as the sheet-shaped member, the shape is stable, so that the aerosol-forming base material 23 can be satisfactorily supported.

Further, as the sheet-shaped member constituting the shaft-shaped member 31, 131,231, the member impregnated or printed with the above-mentioned flavor additive can be used. In these cases, it is possible to easily increase the variation in aroma and taste simply by changing the flavor additive to be impregnated or printed on the shaft-shaped members 31, 131, 231 without changing the raw material of the aerosol-forming base material 23. .. The same effect can be obtained by supporting microcapsules containing flavor additives on the shaft-shaped members 31, 131, 231.

Further, when the support 230 includes a plurality of shaft-shaped members 231 (see, for example, FIG. 13), the flavor additives impregnated in each shaft-shaped member 231 may be different. This adds a different flavor to the aerosol, improving its aroma and taste.

Further, as the sheet-shaped member constituting the shaft-shaped member 31, 131,231, any kind such as a porous one and an embossed one can be used.

Further, although the embodiment of the present invention has been described by taking the case where the number of the shaft-shaped members 231 is two as an example, the number of the shaft-shaped members is not limited in the present invention. That is, the number of shaft-shaped members may be three or more.

Further, the shaft-shaped members 31, 131, 231 do not necessarily have a structure in which a thin sheet-shaped member is spirally wound. As long as the aerosol-forming base material 23 can be supported, for example, it may be a hollow cylinder formed by winding a sheet-shaped member once.

As the raw material of the aerosol forming base material 23, various raw materials can be used in addition to those exemplified above. For example, the raw materials disclosed in Japanese Patent No. 6371927, Japanese Patent No. 6371928, and Japanese Patent No. 6516907 can also be applied to the present invention.

The shape of the aerosol-forming base material 23 is, for example, rod-shaped, granular, powder-shaped, strip-shaped, wound sheet, folded sheet, fibrous, crimped sheet, or crimped fiber. Examples include lumps, lumps, flakes, viscous, highly viscous clays, gels, slimes, tablets, and pastes. Those having these shapes can be used alone or in combination of two or more thereof.

Further, the shape of the aerosol-forming base material 23 may be, for example, a strand, a porous shape, or the like. In order to make it porous, it can be formed by, for example, piercing a dried sheet several times with a plurality of needles (other methods may be used).

The shape of the powdery or granular aerosol-forming substrate 23 may be, for example, in the form of granules, pellets, or the like.

The powdery or granular aerosol-forming substrate 23 may be hardened into a block, or may be made into a paste by adding a little water or oil.
