Modes for Carrying Out the Invention

[0010] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0011] (First Embodiment) FIG. 1 is a cross-sectional view of a cartridge 1 for a smoking device according to a first embodiment of the present invention. As shown in FIG. 1 As shown, the cartridge 1 for a smoking device according to the first embodiment includes a heating element 20, a support 30 and a mouthpiece 40. The heating element 20, the support 30, and the mouthpiece 40 are arranged side by side on the central axis C1. And the heating element 20, the support 30, and the mouthpiece 40 are wound and integrated by a sheet-like outer member 10. The outer member 10 is made of, for example, paper.

[0012] Here, the cartridge 1 for a smoking device shown in FIG. 1 has, for example, a diameter of 6.5 to 7.5 mm and is formed to have a length of 40 to 60 mm. Also, the heating element 20 has a length of 10 to 25 mm Of course, the cartridge 1 for a smoking device may be formed in other dimensions.

[0013] The heating element 20 is formed in a cylindrical shape by winding an aerosol-forming substrate 23, which is a filling material, with a sheet-like packaging member 25, and the aerosol-forming substrate 23 is exposed at both ends thereof. That is The both ends of the heating element 20 are not covered with a lid member (for example, paper). The packaging member 25 is made of, for example, paper, but any sheet-like member may be used regardless of the material. Note that the packaging member 25 may be omitted by directly winding the aerosol-forming substrate 23 with the outer member 10, or the aerosol-forming substrate 23 may be covered with a lid member. substrate 23 with the outer member 10, or the aerosol-forming substrate 23 may be covered with a lid member. substrate 23 with the outer member 10, or the aerosol-forming substrate 23 may be covered with a lid member.

[0014] The aerosol-forming substrate 23 is specifically composed of a smoking material made from a tobacco plant or a non-tobacco plant, which will be described in detail later, as a raw material. The aerosol-forming substrate 23 is, for example, formed by bundling strip-shaped members and is arranged such that its axial direction (longitudinal direction) is along the central axis C1. and is arranged such that its axial direction (longitudinal direction) is along the central axis C1.

[0015] When the aerosol-forming substrate 23 is formed of a strip-shaped member, the cross-section perpendicular 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, in the range of 1.5:1 to 30:1 which is preferable. Also, the length of the aerosol-forming substrate 23 is preferably substantially the same as the length of the body 20 to be heated. As an example of the dimensions of the aerosol-forming substrate 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 substrate 23 is not limited to a strip-shaped member. For example, it may be a rod-shaped member

[0016] or a powdery or paste-like member. Further, the aerosol forming substrate 23 may be a combination of a strip-shaped member and a powdery member, a combination of a strip-shaped member and a rod-shaped member a combination of a rod-shaped member and a powdery member, or a combination of a strip-shaped member, a rod-shaped member and a powdery member. In these cases, it is preferable that at least a part of the raw materials of each member is different, as the aroma and taste are improved. The mouthpiece 40 is a part that constitutes the suction port of the smoking implement cartridge 1 and is formed using, for example, paper or the like. Also, the mouthpiece 40 may include a cellulose acetate filter or the like that removes fine particles. Part of the fine particles in the water vapor or aerosol generated by the body 20 to be heated

[0017] is filtered by the filter of this mouthpiece 40. The support 30 is composed of a single shaft member 31 formed by winding a thin sheet-like member (for example, paper, polymer sheet, rubber sheet, metal sheet etc.) into a cylindrical shape. The shaft member 31 is

[0018] , it is arranged such that its axial direction (longitudinal direction) is along the central axis C1 of the smoking implement cartridge 1 . One end of the shaft-like member 31 abuts against the aerosol-forming substrate 23, and the other end abuts against the mouthpiece 40, thereby restricting the axial movement of the aerosol-forming substrate 23. In other words, the detachment of the aerosol-forming substrate 23 from the heating body 20 is suppressed.

[0019] In this embodiment, the diameter of the shaft-like member 31 is smaller than the diameter of the heating body 20 and is approximately 2 / 3 . An annular space S1 is formed between the outer peripheral surface of the shaft-like member 31 and the exterior member 10. This space S1 constitutes a flow path through which the aerosol flows. Note that the diameter of the shaft-like member 10 0 is arbitrary and may be approximately equal to the diameter of the heating body 20. In this case, almost no space S1 will be formed. Also, the shaft-like member 100 may be arranged generally along the central axis C1 of the smoking implement cartridge 1 and may be arranged in a slightly inclined state without problem.

[0020] FIG. 2 is a cross-sectional view taken along line II-II of FIG. 1, and FIG. 3 is a perspective view of the support 30 (shaft-like member 31). As shown in FIGS. 2 and 3, the shaft-like member 31 is formed by winding a sheet-like member multiple times in a spiral shape, and the inside thereof is formed such that the aerosol can pass through. Specifically, in a cross-section perpendicular to the axial direction of the shaft-like member 31, a spiral flow path 35 is uniformly formed along the axial direction of the shaft-like member 31. The aerosol reaches the mouthpiece 40 while being cooled in the process of flowing through this flow path 35.

[0021] Further, the width W of the flow path 35 is sized such that the aerosol-forming substrate 23 cannot pass through. This prevents the aerosol-forming substrate 23 from clogging in the flow path 35. For example, when the aerosol-forming substrate 23 is formed in powder or granular form, the width W of the flow path 35 may be made smaller than the average particle diameter of the aerosol-forming substrate 23. Also, when the aerosol-forming substrate 23 is formed in strip or rod form, the width W of the flow path 35 may be made smaller than the long side of the cross section of the aerosol-forming substrate 23.

[0022] Next, specific examples of the raw materials used as the aerosol-forming substrate 23 will be described. The aerosol-forming substrate 23 is composed of any one or a combination of the following raw materials.

[0023] The aerosol-forming substrate 23 uses a tobacco plant or a non-tobacco plant as a raw material. Examples of the tobacco plant include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. Examples of the non-tobacco plant include plants other than tobacco plants. Preferred parts of the non-tobacco plant include leaves, pulp, seeds, roots (bulbous roots, tuberous roots, etc.), stems, tubers, skins (stem bark, tree bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches, etc.

[0024] Note that the "plant" referred to in this specification means a group relative to animals, and in addition to organisms such as grasses and trees that have roots and are fixed in place and alive, it also includes algae such as microalgae and seaweeds, and fungi such as mushrooms.

[0025] The aerosol-forming substrate 23 is, for example, obtained by appropriately mixing an aerosol former that generates an aerosol, microcrystalline cellulose, an additive for adding flavor, a preservative, a binder or a thickener, etc. to dried and pulverized non-tobacco plants, and then pulverizing or classifying them into a powder or granular form, or into a paste form. ​​​​​​​​​​​​​ It is formed into a string shape. Further, the aerosol-forming base material 23 is formed into a sheet shape and then cut to have a predetermined width and length to be made into a strip shape or a rod shape.

[0026] For example, when the part of the non-tobacco plant is a leaf, preferably tea can be used. Teas not only differ in the plants that become tea, but also become different teas depending on the processing method even for the same plant . Specifically, for example, Japanese tea, black tea, ashitaba tea, sweet tea, amacha zuru tea, aloe tea, ginkgo leaf tea, oolong tea, turmeric tea, white back nightshade tea, ezoukogii tea, big leaf tobacco tea, ka kichodoshi tea, persimmon leaf tea, chamomile tea, camomile tea, kawarakimei tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, kukicha tea, yawata leaf tea, black soybean tea, gennoshokko tea, brown rice tea, burdock tea, comfrey tea, hibiscus tea, cherry tea, saffron tea, shiitake tea, perilla tea, jasmine tea, shi oga tea, mugwort tea, sekkisho tea, senburi tea, buckwheat tea, tara no ki tea, dandelion tea, sweet tea, dokudami tea, eucommia tea, adzuki bean tea, chickweed tea, nezumimochi tea, coix tea, habu tea , loquat leaf tea, pu-erh tea, red flower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea , eucalyptus tea, luohanguo tea, rooibos tea, bitter melon tea, etc. can be mentioned. Regarding these teas , the tea leaves after drinking can be used. By using tea leaves or the like, expensive teas and the like can be reused and effectively utilized.

[0027] Furthermore, extracts, so-called extracts and processed products of the non-tobacco plants exemplified above can also be used. Examples of the form of the extract include liquid, water candy, powder, granule, solution, etc.

Among them However, glycerin and propylene glycol are preferred.

[0029] Microcrystalline cellulose as a raw material for the aerosol-forming substrate 23 is, for example, obtained by partially depolymerizing α-cellulose obtained from the pulp of fibrous plants with an acid, and removing the soluble part from cellulose and appropriately crystallizing the insoluble part. is. .

[0030] Microcrystalline cellulose may remain in powder form or may be dispersed in a solvent such as water to form a suspension. In this case, for dispersion in a solvent, a high-speed stirrer, a high-pressure homogenizer, or the like can be used.

[0031] Furthermore, a flavor additive for adding flavor as a raw material for the aerosol-forming substrate 23 is also preferably used. Examples of flavor additives include peppermint, cocoa, coffee, tea extracts, powdered catechins of tea extracts, and the like. As preservatives, those used in foods are preferred. For example, sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, and the like are listed.

[0032] Menthol and a water-insoluble crosslinked polymer (preferably poly vinyl pyrrolidone) may be contained in the aerosol-forming substrate 23. A water-insoluble crosslinked polymer is combined with menthol. By combining them, the sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long time. This is possible. Here, menthol is not limited to those obtained from natural products, and synthetic products are also acceptable. Further, those containing peppermint, mint, peppermint oil, and other menthol may be used as well.

[0033] The flavor additive is provided in 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, a capsule containing the flavor additive may be embedded in the wall portion of the mouthpiece 40 so that the flavor additive is provided in the mouthpiece 40. Or, a capsule containing the flavor additive may be disposed between the mouthpiece 40 and the heated body 20 in such a manner. When the flavor additive is encapsulated, the smoker can break the capsule by pressing it with a finger and volatilize the aromatic components of the flavor additive at a desired timing. Further, when the flavor additive is encapsulated in microcapsules, for example, the microcapsules containing the flavor additive may be provided on the heated body 20. Of course, the microcapsules (capsules 60) may be provided on the support 30 (see FIG. 7B). Of course, the microcapsules (capsules 60) may be provided on the support 30 (see FIG. 7B). As the binder or thickener as a raw material of the aerosol forming substrate 23, gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, for example, hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, and methyl

[0034] Further, when the flavor additive is encapsulated in microcapsules, for example, the microcapsules containing the flavor additive may be provided on the heated body 20. Of course, the microcapsules (capsules 60) may be provided on the support 30 (see FIG. 7B). Of course, the microcapsules (capsules 60) may be provided on the support 30 (see FIG. 7B).

[0036] (Method for producing an aerosol-forming substrate) The method for producing the aerosol-forming substrate 23 described above will be described separately for each step. Aero The production process of the sol-forming substrate 23 includes a drying and pulverizing process in which the tobacco plant or non-tobacco plant as the main raw material is dried and pulverized and weighed, etc., and a preparation process in which pretreatment and weighing of other raw materials are performed, and A mixing process in which the raw materials are mixed to form a composition, and a filler forming process in which the composition is formed. have. Yes.

[0037] In the drying and pulverizing process, in order to use the tobacco plant or non-tobacco plant as the main raw material (for example Leaves, seeds, dried fruits, stems, barks, roots, etc.) are processed into a predetermined pulverized product At that time, it is preferable to adjust the moisture content to a convenient amount 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. By setting it within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. Furthermore, the drying and pulverizing process may be provided with a sieving process for sieving the pulverized product, and it can be adjusted to a desired particle size and put into the mixing process. ° C or lower. By setting it within this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. Furthermore, the drying and pulverizing process may be provided with a sieving process for sieving the pulverized product, and it can be adjusted to a desired particle size and put into the mixing process. In the preparation process, the raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation process and put into the mixing process.

[0038] In the preparation process, the raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation process and put into the mixing process. Input.

[0039] In the mixing process, a normal mixer can be used. For example, in the form where the raw materials in the mixing tank are mixed while applying shear force with stirring blades is preferably used.

[0040] In the filler forming process, after forming the composition in which various raw materials are mixed into a thin sheet shape, by cutting it, the aerosol forming substrate 23 in the shape of a strip or a rod is formed. In this embodiment, in order to make a thin sheet, a plurality of roll mills are prepared. When using a plurality of roll mills, by compression due to being pushed into the narrow rolls and shear due to the roll speed difference, while performing kneading, dispersion, etc., it is possible to make a sheet of a desired thickness with a doctor blade, which is preferable. Also, it can be produced using a press roller or a press machine.

[0041] Also, in order to obtain the aerosol forming substrate 23 in powder or granular form, it is preferable to appropriately pulverize or classify the above composition. The average particle diameter of the aerosol forming substrate 23 in powder or granular form is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less. This average particle diameter is obtained, for example, by the sieving method described in JIS K 0069:1992. That is, this average particle diameter refers to the diameter corresponding to 50% of the mass obtained by integrating the mass from the sieve with the larger mesh opening for the test results using a plurality of sieves. Also, the particle diameter at the integrated value of 50% in the particle size distribution obtained by the laser diffraction / scattering method may be used as the average particle diameter.

[0042] In the filler forming process, other methods such as passing the composition through an orifice by applying pressure for forming You may use the means. Also, in the filler forming step, if necessary, non-tobacco plants, aerosol solformers, binders or thickeners, flavor additives, preservatives, etc. may be further added, and water or the like may be added.

[0043] The thickness of the sheet obtained in the filler forming 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 into a predetermined width by a cutter , such as a rotary cutter with a rotary blade method.

[0044] Here, when imparting adhesiveness to the surface of the aerosol forming substrate 23, there is no particular limitation as long as it is a means capable of imparting adhesiveness, but it is sufficient to adhere at least a part of the aforementioned binder . By imparting adhesiveness, when combining the strip-shaped or rod-shaped aerosol forming substrate 23 with the powdery, granular or paste-like aerosol forming substrate 23, the powdery, granular or paste-like aerosol forming substrate 23 can be stably held on the surface of the strip-shaped or rod-shaped aerosol forming substrate 23.

[0045] (Method of using a cartridge for a smoking device) The method of using the cartridge 1 for a smoking device will be described. FIG. 4 is a cross-sectional view of the cartridge 1 for a smoking device inserted into the smoking device 70. The cartridge 1 for a smoking device is used by being mounted on a heated smoking device 70. The smoking device 70 has an insertion portion 72 for inserting the cartridge 1 for a smoking device. A needle-shaped or blade-shaped heating portion 75 is provided in the insertion portion 72. When the heating portion 75 generates heat in a state where the cartridge 1 for a smoking device is inserted into the insertion portion 72, an aerosol is generated from the aerosol forming substrate 23. In this state, the smoker When the mouthpiece 40 is held and suctioned, the aerosol flows through the support 30 (flow path 35 and space S1) and the mouthpiece 40 in that order and into the smoker's mouth.

[0046] According to the smoking implement cartridge 1 according to the first embodiment configured as described above, the following effects can be achieved.

[0047] Since the support 30 is composed of the shaft-like member 100 formed by winding a thin sheet-like member in a spiral shape, the structure of the support 30 is simple and the manufacturing cost can also be reduced. Further, the shaft-like member 100 is configured by winding a sheet-like member in a spiral shape, and a spiral flow path 35 is formed inside, so it does not have a thick outer peripheral portion as in the above prior art (Patent Document 1). Therefore, the end portion (one side of the sheet-like member) of the shaft-like member 100 is dispersed and contacts the end face of the aerosol forming base material 23. In other words, unlike the above prior art, the outer peripheral portion of the support element does not locally contact the end portion of the aerosol forming base material. Therefore, by heating the aerosol forming base material 23, the generation amount and flow unevenness of the generated aerosol are suppressed. As a result, the aroma and taste of the aerosol are improved. Further, as the aerosol passes through the space S1 and the spiral flow path 35, the aerosol is effectively cooled. In particular, since the support 30 is configured by winding a sheet-like member, when the aerosol passes through the flow path 35, the contact area between the aerosol and the sheet-like member is large. Therefore, the heat of the aerosol is exchanged with the sheet-like member, and the aerosol is effectively cooled. As a result, the smoker's feeling of inhaling the aerosol becomes good.

[0048] Further, the support 30 is interposed between the aerosol forming base material 23 and the mouthpiece 40, and the Since the axial movement of the aerosol-forming substrate 23 is restricted, when the smoking implement cartridge 1 is inserted into the smoking implement 70, the position of the aerosol-forming substrate 23 is prevented from shifting. Thus, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stabilized, and a good aerosol is generated. Furthermore, by providing the support 30, axial deformation can be prevented when the smoking implement cartridge 1 is inserted into the smoking implement 70. When the smoking implement cartridge 1 is inserted into the smoking implement 70, the position of the aerosol-forming substrate 23 is prevented from shifting. Thus, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stabilized, and a good aerosol is generated. Furthermore, by providing the support 30, axial deformation can be prevented when the smoking implement cartridge 1 is inserted into the smoking implement 70. Since the axial movement of the aerosol-forming substrate 23 is restricted, when the smoking implement cartridge 1 is inserted into the smoking implement 70, the position of the aerosol-forming substrate 23 is prevented from shifting. Thus, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stabilized, and a good aerosol is generated. Furthermore, by providing the support 30, axial deformation can be prevented when the smoking implement cartridge 1 is inserted into the smoking implement 70.

[0049] If the diameter of the support 30 is made substantially equal to the diameter of the heated body 20, since the outer member 10 is supported by the outer peripheral surface of the support 30, deformation in the diameter direction when the smoking implement cartridge 1 is grasped by a finger can also be prevented. If the diameter of the support 30 is made substantially equal to the diameter of the heated body 20, since the outer member 10 is supported by the outer peripheral surface of the support 30, deformation in the diameter direction when the smoking implement cartridge 1 is grasped by a finger can also be prevented. Furthermore, by providing the support 30, axial deformation can be prevented when the smoking implement cartridge 1 is inserted into the smoking implement 70.

[0050] Next, a modified example of the smoking implement cartridge 1 according to the first embodiment will be described.

[0051] (Modified Example 1-1) FIG. 5 is a cross-sectional view of the support 30-1 according to Modified Example 1-1. Note that FIG. 5 is a cross-sectional view taken at the same position as the II-II line in FIG. 1. The shaft-like member 31-1 shown in FIG. 5 is formed into a rectangular tube shape by winding a sheet-like member in a spiral shape, and its cross-sectional outer shape forms a substantially rectangle. And, in the cross-section shown in FIG. 5, a spiral flow path 35-1 is formed. Even with such a configuration, the same operational effects as those of the above-described first embodiment are exhibited. Note that the cross-sectional outer shape may be a square, or a polygon such as a pentagon or a hexagon. Even with such a configuration, the same operational effects as those of the above-described first embodiment are exhibited.

Note that FIG. 6 is a cross-sectional view taken at the same position as the II-II line in FIG. 1. The shaft-like member 31-2 shown in FIG. 6 is formed into a rectangular tube shape by winding a sheet-like member in a spiral shape, and its cross-sectional outer shape forms a substantially rectangle. And, in the cross-section shown in FIG. 6, a spiral flow path 35-2 is formed. Even with such a configuration, the same operational effects as those of the above-described first embodiment are exhibited. Note that the cross-sectional outer shape may be a square, or a polygon such as a pentagon or a hexagon. The member is wound in a spiral shape to form a triangular tube shape, and its cross-sectional outer shape forms a substantially equilateral triangle. Thus, in the cross-section shown in FIG. 6, a spiral flow path 35-2 is formed.

[0054] Even with such a configuration, the same operational effects as those of the above-described first embodiment are achieved. Note that the cross-sectional outer shape may be an isosceles triangle, a right triangle, or the like.

[0055] (Modification 1-3) FIG. 7A is a view showing the state of the support 30-3 according to Modification 1-3 before completion, and FIG. 7B is a perspective view (after completion) of the support 30-3 according to Modification 1-3. In this example, as shown in FIG. 7A, a trapezoidal sheet-shaped member is prepared by cutting the portion indicated by the two-dot chain line of a rectangular sheet-shaped member. Then, when this trapezoidal member is wound around the short side in the direction of the arrow in the figure, a conical recess 37 is formed as shown in FIG. 7B. And, as shown in FIG. 7B, the support 30-3 according to Modification 1-3 has a capsule 60 provided in the recess 37 formed at its end. This capsule 60 is for changing the aroma and taste with respect to the aerosol, and various flavor additives described above can be used.

[0056] According to this Modification 1-3, since the aerosol is flavored by the capsule 60, the aroma and taste can be improved. Also, by crushing or biting the capsule 60 by hand, a deeper taste can be realized. Further, since the capsule 60 is provided inside the support 30-3, even if vibration or impact is applied to the smoking implement cartridge, it is difficult for the impact to be transmitted to the capsule 60. As a result, it is possible to prevent the capsule 60 from being broken and the flavor from escaping.

[0057] 60. In addition, since the capsule 60 is provided at a position generally along the central axis C, when the capsule 60 is crushed, the flavor additive spreads uniformly inside the support 30-3 and mixes uniformly into the aerosol. Therefore, a deeper flavor is obtained.

[0058] (Second Embodiment) Next, the smoking implement cartridge 2 according to the second embodiment of the present invention will be described. The smoking implement cartridge 2 according to the second embodiment has basically the same configuration as the smoking implement cartridge 1 according to the first embodiment, but the configuration of the support is different. Therefore, in the following description, the description will focus on this difference, and the description overlapping with the first embodiment will be omitted.

[0059] FIG. 8 is a cross-sectional view of the smoking implement 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. 8. As shown in FIG. 8, the smoking implement cartridge 2 according to the second embodiment includes a heated body 20, a support 130, and a mouthpiece 40.

[0060] 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. Inside the axial member 131, a flow path 135 through which the aerosol flows is formed in a spiral shape. The axial member 131 is configured such that its end 132 is stretched in the axial direction (longitudinal direction) so as to have a reduced diameter toward the tip side. As a result, the axial member 131 has some elasticity in the axial direction. When the axial member 131 is arranged such that its axial direction is along the central axis C1 of the smoking implement cartridge 1, one end of the axial member 131 is in the aerosol shape 1 has some elasticity in the axial direction. When the axial member 131 is arranged such that its axial direction is along the central axis C1 of the smoking implement cartridge 1, one end of the axial member 131 is in the aerosol shape 1, one end of the axial member 131 is in the aerosol shape The other end 132 is pressed slightly against the mouthpiece 40. In this way, the movement of the aerosol-forming substrate 23 in the axial direction is restricted.

[0061] According to this configuration, in addition to providing the same effects as those of the first embodiment, the shaft-shaped member 131 Since the aerosol-forming substrate 23 has elasticity in both directions, the aerosol-forming substrate 23 is supported even better. In addition, when the cartridge 2 for a smoking article is inserted into the smoking article 70, the aerosol-forming base material 23 is heated. It is possible that the aerosol is pushed inward by the heat part 75. The base material 23 presses the shaft member 131 in the axial direction. According to this, the end face of the shaft-shaped member 131 facing the aerosol-forming substrate 23 is recessed, and Since the aerosol-forming substrate 23 has elasticity in the direction of the axis, the aerosol-forming substrate 23 is pressed against the aerosol-forming substrate 23, and the aerosol-forming substrate 23 is pressed against the aerosol-forming substrate 23. The central portion is displaced inward. As a result, the smoking article 70 of the cartridge 2 for the smoking article The insertion is smooth.

[0062] Next, a modified example of the cartridge 2 for a smoking article according to the second embodiment will be described.

[0063] (Variation 2-1) Fig. 10 is a perspective view of a support 130-1 according to a modified example 2-1. 131-1 is a flexible sheet-like member (e.g., PPS (polyphenylene sulfide) Thermoplastic resins such as PI (polyimide) or thermosetting resins such as PI (polyimide) are wound in a spiral shape. Then, a flow path 135-1 through which the aerosol flows is formed inside the shaft-shaped member 131-1. is formed.

[0064] Even with this configuration, elastic force can be applied to the support 130-1 in the axial direction. 、It exhibits the same operational effects as those of the above-described second embodiment.

[0065] (Modification Example 2-2) FIG. 11 is a cross-sectional view of the smoking implement cartridge 2 including the support 132-2 according to Modification Example 2-2. 、FIG. 12 is a cross-sectional view of the smoking implement cartridge 2 showing the state in which the support 132-2 according to Modification Example 2-2 is displaced. It is a cross-sectional view of the ridge 2.

[0066] As shown in FIG. 11, the support 132-2 according to Modification Example 2-2 is composed of one axial member 131-2 formed by winding a thin sheet-like member in a spiral shape to form a cylindrical shape. Inside the axial member 13 1-2, a flow path 135-2 through which aerosol flows is formed in a spiral shape. And when one end of the axial member 131-2 is pushed axially, as shown in FIG. 9, the central portion of one end face is recessed and the end portion on the other end side is stretched. Then, when the external force applied in the axial direction to the axial member 131-2 is released, it returns to its original shape. That is, the axial member 131-1 is configured to be axially elastically deformable. This configuration itself is the same as the axial member 31 shown in FIG. 1, but the axial length of the axial member 131-2 is shorter than that of the axial member 31. Therefore, a space S1 is formed between the axial member 131-2 and the mouthpiece 40. Also, the outer peripheral surface of the axial 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. According to this configuration, it exhibits the same operational effects as those of the above-described second embodiment. Further, the radial deformation of the exterior member 10 is suppressed by the outer peripheral surface of the axial member 131-2.

[0067] direction

[0068] According to this configuration, it exhibits the same operational effects as those of the above-described second embodiment. Furthermore, the radial deformation of the exterior member 10 is suppressed by the outer peripheral surface of the axial member 131-2.

[0069] ​​​​​ Also, when inserting the smoking implement cartridge 2 into the smoking implement 70, even when the aerosol-forming substrate 23 is pressed against the heating unit 75 and extruded therein, as shown in FIG. 12, the central portion of the shaft-like member 131-2 is displaced so as to be recessed in the axial direction (dotted line in the figure), and thus the insertion of the smoking implement cartridge 2 into the smoking implement 70 is smooth.

[0070] (Third Embodiment) Next, the smoking implement cartridge 3 according to the third embodiment of the present invention will be described. The smoking implement cartridge 3 according to the third embodiment has basically the same configuration as the smoking implement cartridge 1 according to the first embodiment, but mainly differs in the number of supports. Therefore, in the following description, the description will focus on these differences, and the description overlapping with the first embodiment will be omitted.

[0071] FIG. 13 is a cross-sectional view of the support 23 0 used in the smoking implement 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. 1. As shown in FIG. 13, in the present embodiment, the support 230 is composed of two shaft-like members 231 . The shaft-like member 231 is configured in the same manner as the shaft-like member 31 according to the first embodiment. That is, the shaft-like member 231 is formed into a cylindrical shape by winding a thin sheet-like member in a spiral shape, and a flow path 235 through which aerosol flows is formed in a spiral shape inside. And the two shaft-like members 23 1 are bundled together by a sheet-like binding member 15. The binding member 15 is made of, for example, paper, but a rubber member, a film sheet, etc. may be used.

[0072] According to this configuration, the same operational effects as those of the first embodiment are achieved. Further, the two shaft-like members Since 231 is bundled and integrated by the bundling member 15, the handling of the support 230 is easy. Therefore, the operation of winding the heating element 20, the support 230, and the mouthpiece 40 with the exterior member 10 becomes simple. In addition, since the support 230 is constituted by two shaft-like members 231, the rigidity of the support 230 is increased, and axial deformation of the smoking article cartridge 3 can be further prevented. Note that the number of the shaft-like members 231 is not limited to two, and three or more may be used.

[0073] Next, a modification of the smoking article cartridge 3 according to the third embodiment will be described.

[0074] (Modification 3-1) FIG. 14 is a cross-sectional view of a support 230-1 according to Modification 3-1. Note that FIG. 14 is a cross-sectional view taken at the same position as the line II-II in FIG. 1. The support 230-1 shown in FIG. 14 has a configuration in which two shaft-like members 231 and 232 are bundled and integrated by a bundling member 15. However, the shaft-like member 231 and the shaft-like member 232 have different cross-sectional shapes (outer shapes) orthogonal to the axial direction (longitudinal direction). Specifically, the shaft-like member 231 has a substantially circular cross-sectional outer shape (see FIG. 2), while the shaft-like member 232 has a substantially triangular cross-sectional outer shape (see FIG. 6). Even with such a configuration, the same effects as those of the third embodiment can be obtained. Note that the cross-sectional outer shapes of the shaft-like member 231 and the shaft-like member 232 only need to be different from each other, and are not limited to the combination of the circular shape and the triangular shape shown in FIG. 14.

[0075] (Modification 3-2) FIG. 15 is a cross-sectional view of a support 230-2 according to Modification 3-2. Note that FIG. 15 is a cross-sectional view taken at the same position as the line II-II in FIG. 1. The support 230-2 shown in FIG. 15 has a configuration in which two It coincides with the third embodiment in that it includes one shaft-like member 231, but the configuration for bundling the two shaft-like members 231 is different. Specifically, in this example, one shaft-like member 231 (the left shaft-like member) is wrapped by a bundling portion 231a which is a part of the other shaft-like member 231 (the right shaft-like member), and the end portion 231b of this bundling portion 231a is adhered to the outer peripheral surface of the other shaft-like member 231, so that the two shaft-like members 231 are bundled. Even with this configuration, the same operating effects as those of the third embodiment are achieved. Also, in this example, since the bundling member 15 is unnecessary, there is an advantage of being able to reduce the number of parts.

[0076] Here, in this example, a configuration in which one shaft-like member 231 is wrapped by the bundling portion 231a of the other shaft-like member and bundled has been described, but a configuration in which one sheet-like member is spirally wound from both ends to form two shaft-like members can also be adopted. Even with this configuration, since the two shaft-like members are integrated without using the bundling member 15, it is easy to handle and the number of parts can also be reduced. Note that the present invention is not limited to the above embodiments, and various modifications are possible without departing from the gist of the present invention. All technical matters included in the technical idea described in the claims are the subject of the present invention. The above embodiments show preferred examples, but those skilled in the art can realize various alternative examples, modified examples, deformed examples, or improved examples

[0077] from the content disclosed in this specification, and these are included in the technical scope described in the appended claims. For example, the sheet-like members constituting the shaft-like members 31, 131, and 231 are as described above Although the above embodiments show preferred examples, those skilled in the art can, from the content disclosed in this specification, realize various alternative examples, modified examples, deformed examples, or improved examples and these are included in the technical scope described in the appended claims. For example, the sheet-like members constituting the shaft-like members 31, 131, and 231 are as described above

[0078] For example, the sheet-like members constituting the shaft-like members 31, 131, and 231 are as described above , any material such as paper, polymer sheet, rubber sheet, metal sheet, resin sheet, etc. can be used However, when it is desired to enhance the cooling effect of the aerosol, it is preferable to use a metal sheet. Also, when using a shape memory alloy as the sheet-like member, since the shape is stable, the aerosol forming substrate 23 can be well supported.

[0079] Also, as the sheet-like member constituting the shaft-like members 31, 131, 231, the above-mentioned member impregnated or printed with a flavor additive can be used. In these cases, without changing the raw material of the aerosol forming substrate 23, by simply changing the flavor additive impregnated or printed on the shaft-like members 31, 131, 231, it is possible to easily increase the variations in aroma and taste. Even when microcapsules encapsulating a flavor additive are carried on the shaft-like members 31, 131, 231, the same effect can be achieved.

[0080] Also, when the support 230 includes a plurality of shaft-like members 231 (see, for example, FIG. 13), the flavor additives impregnated in each shaft-like member 231 may be different. By doing so, different flavors are added to the aerosol, and the aroma and taste are improved.

[0081] Also, the sheet-like member constituting the shaft-like members 31, 131, 231 can be of any type, such as a porous one, one subjected to embossing, etc.

[0082] Also, although the embodiments of the present invention have been described by taking the case where there are two shaft-like members 231 as an example, in the present invention, the number of shaft-like members is not limited. That is, the number of shaft-like members may be three or more.

[0083] ​​In addition, the shaft-shaped member 31, 131, 231 does not necessarily have to be a thin sheet-shaped member wound in a spiral shape. As long as it can support the aerosol-forming substrate 23, it is not necessary to use a structure that supports the aerosol-forming substrate 23. It may be a hollow cylinder formed by winding a rod-shaped member once.

[0084] In addition to the above-mentioned examples, various raw materials for the aerosol-forming substrate 23 may be used. Raw materials can be used. For example, Patent No. 6371927 and Patent No. 6371928 and the raw materials disclosed in Japanese Patent No. 6516907 can also be applied to the present invention.

[0085] The shape of the aerosol-forming substrate 23 may be, for example, a rod, a granule, a powder, a strip, or a sheet. Rolled, folded sheet, fibrous, crimped sheet, crimped fiber In the form of lumps, flakes, viscous clay, gel, slime, or tablets These forms include one or more of these mixed together. It can be used in combination.

[0086] The shape of the aerosol-forming substrate 23 may be, for example, a strand, a porous shape, or the like. To make it porous, for example, the dried sheet can be punched several times with multiple needles. It can be formed by piercing or other methods.

[0087] The powder or granular aerosol-forming base material 23 may be in the form of, for example, granules, pellets, etc. It may also be in the form of

[0088] The powder or granular aerosol-forming base material 23 may be solidified into a block shape or may be slightly hydrated. Or you can add oil to make a paste. [Explanation of symbols]
