Mode 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 smoking article cartridge 1 according to a first embodiment of the present invention. As shown in FIG. 1 the smoking article cartridge 1 according to the first embodiment includes a heatable body 20, a support member 3 0, and a mouthpiece 40. The heatable body 20, the support member 30, and the mouthpiece 40 are arranged side by side on the central axis C1. Then, the heatable body 20, the support member 30, and the mouse piece 40 are wound and integrated by a sheet-like outer member 10. The outer member 1 0 is made of, for example, paper.

[0012] Here, the smoking article cartridge 1 shown in FIG. 1 has, for example, a diameter of 6.5 to 7.5 mm, and a length of 40 to 60 mm. Further, the heatable body 20 has a length of 10 to 25 mm Of course, the smoking article cartridge 1 may be formed in other dimensions.

[0013] The heatable body 20 is located inside the outer member 10 and is disposed in a cylindrical space extending from one end portion facing the support member 30 to the other end portion which is the side to be inserted into a heating type smoking device 70 described later. And the "outer diameter of the heatable body" in the present invention is defined as the outer diameter of this cylindrical space. In the present embodiment, the heatable body 20 (aerosol-forming substrate )( ​(23) has a configuration directly covered by the exterior member 10 (see Fig. 1), and the outside of the object to be heated 20 The outer diameter D is the outer diameter of this cylindrical space and is equal to the inner diameter of the exterior member 10. And This outer diameter D has a generally constant value along the central axis C1.

[0014] The object to be heated 20 contains an aerosol-forming substrate 23 that generates an aerosol when heated. Note that the object to be heated 20 contains the aerosol-forming substrate 23 in any form. Such Examples of the form of the aerosol-forming substrate 23 include, for example, a form in which members such as strip-shaped, rod-shaped, and granular members described later are filled at high or low density, a form in which a plurality of strip-shaped, rod-shaped, granular members are provided with a predetermined gap therebetween, and a form composed of a plurality of capsules containing a flavor additive, etc. Of course, forms of the aerosol-forming substrate 23 described below that are not listed above may also be used. Even if the filling state of the aerosol-forming substrate 23 contained in the object to be heated 20 changes inside the exterior member 10 according to the orientation of the smoking implement cartridge 1, the outer diameter D of the object to be heated 20 always remains unchanged and, in the case of this embodiment, is equal to the size of the inner diameter of the exterior member 10 as described above.

[0015]

[0016]

[0016] In addition, in the above, the case where the object to be heated 20 (aerosol-forming substrate 23) is directly covered by the exterior member 10 has been described. However, when the object to be heated 20 has a configuration in which the aerosol-forming substrate 23 is wound by a sheet-like packaging member described later, the size of the outer diameter D of the object to be heated 20 is equal to the size of the outer diameter of the packaging member. For example, when the strip-shaped, rod-shaped, granular aerosol-forming substrate 23 described above is filled in the packaging member at low density, the aerosol-forming substrate Although 23 may move inside the packaging member, the form of the packaging member itself remains unchanged. Therefore, the outer diameter D of the object to be heated 20 also remains unchanged.

[0017] Furthermore, as long as the support member 30 has a function of preventing the movement of the object to be heated 20 regardless of the filling density of the aerosol-forming substrate 23 that constitutes the object to be heated 20, it is included in the "support member" of the present invention. That is, the configurations of the object to be heated 20 and the support member 30 in all the above-described modes are included in the technical scope of the present invention. For example, when the object to be heated 20 is a strip-shaped, rod-shaped, granular, or particulate member and the aerosol-forming substrate 23 is filled with a low density, even if the smoker inserts the needle-shaped or blade-shaped heating part 75 of the smoking device 70 into the aerosol-forming substrate 23 and the aerosol-forming substrate 23 is pushed toward the support member 30, the support member 30 can prevent the movement of the aerosol-forming substrate 23 toward the support member 30 side. For example, when the aerosol-forming substrate 23 that constitutes the object to be heated 20 is composed of strip-shaped, rod-shaped, granular, or particulate members and is filled with a low density, even if the smoker inserts the needle-shaped or blade-shaped heating part 75 of the smoking device 70 into the aerosol-forming substrate 23 and the aerosol-forming substrate 23 is pushed toward the support member 30, the support member 30 can prevent the movement of the aerosol-forming substrate 23 toward the support member 30 side.

[0018] The aerosol-forming substrate 23 is wound by the exterior member 10 and formed into a cylindrical shape. The outer diameter D of the aerosol-forming substrate 23 is equal to the outer diameter D of the object to be heated 20 and is generally a constant value along the central axis C1. The size of this outer diameter D is preferably in the range of, for example, 4.0 mm to 7.5 mm, and more preferably in the range of 5.0 mm to 7.0 mm. If the size of the outer diameter D is set to 4.0 mm or more, it becomes possible to generate a minimum required amount of aerosol. Also, if the size of the outer diameter D is set to 5.0 mm or more, it becomes possible to generate a sufficient amount of aerosol. Furthermore, if the size of the outer diameter D is set to 7.5 mm or less, the object to be heated 20 can be attached to the smoking device 70. Also, if the size of the outer diameter D is set to 7.0 mm or less, the object to be heated 20 can be easily attached to the smoking device 70.

[0019] Also, both ends of the aerosol-forming substrate 23 are not covered by a lid member (e.g., paper) and are exposed. One end 23a of the two ends of the aerosol-forming substrate 23 is the side facing the support member 30, and the other end 23b is the side to be inserted into the insertion portion 72 of the smoking device 70. Here, the "end" as used in this specification includes the end face and the portion within a predetermined range along the central axis C1 from the end face. Note that the heated body 20 may be configured to be wound with a sheet-like packaging member made of, for example, paper, or may be configured to cover the

[0020] aerosol-forming substrate 23 with a lid member. 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. The

[0021] aerosol-forming substrate 23 is configured by bundling strip-shaped members, and is arranged such that its axial direction (longitudinal direction) is along the central axis C1. When the aerosol-forming substrate 23 is composed of strip-shaped members, 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 1:1 to 30:1. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, more preferably in the range of 0.1 mm to 3.0 mm. The length of the short side is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 0.5 mm. The long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

[0022] Of course, the aerosol-forming substrate 23 is not limited to strip-shaped members. For example, it may be a rod-shaped member or a powdery or paste-like member. Also, 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 or a combination of a rod-shaped member and a powdery member, or a configuration consisting of a combination of a strip-shaped member, a rod-shaped member, and a powdery member. In these cases, it is preferable to make at least part of the raw materials of each member different, as the aroma and taste will be improved.

[0023] The mouthpiece 40 is a part that constitutes the suction port of the smoking device cartridge 1 and is formed using, for example, paper or the like. Also, the mouthpiece 40 is formed, for example, to have a diameter of 6.5 mm to 7.5 mm and a length along the central axis C1 of 50 mm or less. Further, the mouthpiece 40 may be formed into a cylindrical shape by winding a sheet-like member made of, for example, paper, or may contain 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 heated body 20 is filtered by the filter of this mouthpiece 40

[0024] The support member 30 is formed into a cylindrical shape by winding a sheet-like member 31 made of, for example, paper once or a plurality of times The support member 30 is disposed between the aerosol-forming substrate 23 and the mouthpiece 40 such that its axial direction is along the central axis C1. The support member 30 is formed, for example, to have a length along the central axis C1 of 50 mm or less. One end of both ends of the support member 30 ​​​​The first end portion 30a is on the side facing one end portion 23a of the aerosol-forming substrate 23, and the other end portion, which is the second end portion 30b, is on the side opposite to the first end portion 30a, that is, the side facing the mouthpiece 40. The first end portion 30a of the support member 30 abuts against the aerosol-forming substrate 23, and the second end portion 30b abuts against the mouthpiece 40. Then, the aerosol passes through the inside of the support member 30.

[0025] The support member 30 has a frustum-shaped through-hole 31a through which the aerosol passes inside, and the shape of the first end portion 30a is different from the shape of the second end portion 30b. Specifically, the sheet-like member 31 constituting the support member 30 is wound so that the diameter becomes smaller toward the second end portion 30b than the first end portion 30a, and thus the inner diameter r1 of the first end portion 30a is larger than the inner diameter r2 of the second end portion 30b. Also, the inner diameter of the support member 30 gradually decreases from the first end portion 30a toward the second end portion 30b. Further, the outer diameter R1 of the first end portion 30a of the support member 30 is larger than the outer diameter R2 of the second end portion 30b.

[0026] The size of the inner diameter r1 of the support member 30 is preferably in the range of, for example, 0.5 mm to 6.5 mm, more preferably in the range of 1.0 mm to 5.0 mm. If the size of the inner diameter r1 is set to 0.5 mm or more, the minimum necessary size of the flow path can be ensured for the aerosol to flow through the through-hole 31a of the support member 30. Also, if the size of the inner diameter r1 is set to 1.0 mm or more, a sufficient size of the flow path can be ensured for the aerosol to flow through the through-hole 31a of the support member 30. Further, if the size of the inner diameter r1 is set to 6.5 mm or less, the minimum necessary thickness of the support member 30 for supporting the heated body 20 can be ensured. Also, the inner diameter r1 ​ If the size is set to 5.0 mm or less, a sufficient support member 3 for supporting the object to be heated 20 can ensure a thickness of 0.

[0027] In addition, the size of the inner diameter r2 of the support member 30 is preferably in the range of, for example, 0.5 mm to 6.5 mm , more preferably in the range of 0.5 mm to 4.5 mm. If the size of the inner diameter r2 is set to 0 .5 mm or more, the minimum necessary flow path size can be ensured for the aerosol to flow through the through hole 31a of the support member 30. Furthermore, if the size of the inner diameter r2 is 6.5 mm or less , the minimum necessary thickness of the support member 30 for supporting the object to be heated 20 can be ensured. Also, if the size of the inner diameter r2 is set to 4.5 mm or less, a sufficient thickness of the support member 30 for supporting the object to be heated 20 can be ensured .

[0028] When manufacturing the support member 30, the sizes of the inner diameters r1 and r2 are appropriately selected within the above ranges so that the flow path size of the support member 30 can be adjusted to ensure a flow path for transferring the aerosol to the mouthpiece 40. Also, the support strength of the object to be heated 20 (aerosol forming substrate 23) by the support member 30 is adjusted so that the object to be heated 20 can be appropriately supported according to the material of the aerosol forming substrate 23 .

[0029] In addition, by appropriately selecting the length along the central axis C1 of the support member 30 and the inner diameters r1 and r2 within the above ranges according to the form of the aerosol forming substrate 23, the inclination angle of the outer peripheral portion of the support member 30 can be adjusted to prevent the aerosol forming substrate 23 from moving toward the mouthpiece 40 . For example, when the aerosol forming substrate 23 is in powder form, granular form or granule (e.g., capsule) ​​​​​In such a case, if the length of the support member 30 is set to be short and the size of the inner diameter r1 is set to be sufficiently larger than the size of the inner diameter r2, the inclination angle of the outer peripheral portion of the support member 30 with respect to the first end portion 30a can be set small. And at this time, the outer peripheral portion of the support member 30 inclines downward from the first end portion 30a toward the second end portion 30b. By doing so, even if the aerosol-forming substrate 23 enters the through hole 31a of the support member 30, the aerosol-forming substrate 23 abuts against the outer peripheral portion of the support member 30 and cannot move toward the mouthpiece 40 side. Therefore, it is possible to prevent the aerosol-forming substrate 23 from moving toward the mouthpiece 40 side within the through hole 31a of the support member 30. Incidentally, if the inner diameter r1 of the support member 30 is made small and the aerosol-forming substrate 23 can be sufficiently supported by the thickness portion between the inner diameter r1 and the outer diameter R1 of the support member 30, regardless of the inner diameter r2, it becomes difficult for the aerosol-forming substrate 23 to enter the through hole 31a of the support member 30. The size of the outer diameter R1 of the support member 30 is preferably in the range of, for example, 4.0 mm to 7.5 mm, and more preferably in the range of 5.0 mm to 7.0 mm. Also, the size of the outer diameter R2 of the support member 30 is preferably in the range of, for example, 1.0 mm to 7.5 mm, and more preferably in the range of 1.5 mm to 6.5 mm. It is preferable to set the size of the outer diameter R1 to be equal to the size of the outer diameter D of the aerosol-forming substrate 23. That is, it is preferable that the dimension of the outer diameter R1 and the dimension of the outer diameter D are the same. By doing so, it is possible to prevent the aerosol-forming substrate 23 from moving toward the support member 30 side through between the first end portion 30a of the support member 30 and the exterior member 10.

[0030]

[0031] ​​​​​​​​​​​​​​​Next, referring to FIG. 2, the relationship between the outer diameter R1 and inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 2 is a longitudinal section of the aerosol-forming substrate 23 viewed from the support member 30 side of a cross-section obtained by cutting the smoking article cartridge 1 shown in FIG. 1 along the line II-II, and the right diagram in FIG. 2 is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side of the same cross-section. Note that in FIG. 2, L1 is a straight line passing through the tops of the aerosol-forming substrate 23 and the support member 30, L2 is a straight line passing through the top of the inner peripheral portion of the support member 30 (sheet-like member 31), L3 is a straight line passing through the bottom of the inner peripheral portion of the support member 30, and L4 is a straight line passing through the bottoms of the aerosol-forming substrate 23 and the support member 30. The outer diameter R1 of the support member 30 is set equal to the outer diameter D of the aerosol-forming substrate 23. As shown in FIG. 2, both the outer diameter R1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Therefore, the first end portion 30a of the support member 30 can support the outer peripheral portion at one end portion 23a of the aerosol-forming substrate 23. Note that if the first end portion 30a of the support member 30 can support the outer peripheral portion of the aerosol-forming substrate 23, the outer diameter R1 may be smaller than the outer diameter D. Also, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3 and is smaller than the outer diameter D of the aerosol-forming substrate 23. Specifically, the inner diameter r1 of the support member 30 is the length obtained by excluding the length (Δr) between L1 and L2 and the length (Δr) between L3 and L4, that is, the thickness (2Δr) of the support member 30 (sheet-like member 31) from the outer diameter R1 (≦ outer diameter D) of the support member 30.

[0032]

[0033]

[0034] ​ corresponds to. Therefore, the first end portion 30a of the support member 30 can be supported by the thick portion of the sheet-like member 31 from the outer peripheral portion of the aerosol-forming substrate 23 to the portion inside the predetermined range.

[0035] The size of the above-described Δr is preferably in the range of, for example, 0.5 mm to 3.5 mm, more preferably in the range of 1.0 mm to 3.25 mm. If the size of Δr is set to 0.5 mm or more, it is possible to secure the minimum thickness of the support member 30 required to support the heated body 20. Further, if the size of Δr is set to 1.0 mm or more, it is possible to secure a sufficient thickness of the support member 30 to support the heated body 20. Furthermore, if the size of Δr is set to 3.5 mm or less, it is possible to secure the minimum size of the flow path required for the aerosol to flow through the through hole 31a of the support member 30. Also, if the size of Δr is set to 3.25 mm or less, it is possible to secure a sufficient size of the flow path for the aerosol to flow through the through hole 31a of the support member 30.

[0036] As described above, since the outer diameter R1 and the inner diameter r1 of the support member 30 have the above-described relationship with respect to the outer diameter D of the aerosol-forming substrate 23, the support member 30 can support not only the outer peripheral portion of the aerosol-forming substrate 23 but also the portion from the outer peripheral portion to the portion inside the predetermined range.

[0037] In FIG. 1, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, but the present invention is not limited to this configuration. As long as one end portion 23a of the aerosol-forming substrate 23 can be supported by the thick portion of the support member 30 (sheet-like member 31), the inner diameter r2 of the support member 30 may be equal to or larger than the inner diameter r1. When the inner diameter r2 of the support member 30 is equal to the inner diameter r1 or larger than the inner diameter r1. ​​​​​​​​When it is equal to, the inner diameter of the support member 30 may be uniform from the first end portion 30a to the second end portion 30b. When the inner diameter r2 of the support member 30 is larger than the inner diameter r1 , the inner diameter of the support member may increase even in the middle of going from the first end portion 30a to the second end portion 30b , or may gradually increase from the first end portion 30a to the second end portion 30b. Furthermore , in both the case where the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and the case where it is larger than the inner diameter r1 , the outer diameter R1 and the outer diameter R2 of the support member 30 may be made equal.

[0038] Note that the support member 30 may be configured such that various fillers are filled in its through hole 31a. Examples of such fillers include granular materials, fibrous materials, porous materials, and flavor additives and the like.

[0039] When granular materials are filled, for example, plastic particles can be adopted. The shape of the granular materials is not particularly limited, and for example, the cross-sectional shape may be round, elliptical, or polygonal. Also, the granular materials may be solid or hollow, and its particle size is preferably, for example, 0.5 mm to 1 mm.

[0040] When fibrous materials are filled, for example, cellulose acetate (CA) fibers or polyester fiber bodies such as polyethylene terephthalate (PET) can be adopted.

[0041] When porous materials are filled, for example, polyolefin resins such as PE and PP, PET resin , CA resin, polylactic acid (PLA), metal foils such as aluminum and the metal itself can be adopted .

[0042] Furthermore, when the above-mentioned granular materials and the like are filled, as the filler, it is mixed into the aerosol Activated carbon, which can remove certain chemicals (such as tar) that have been absorbed, and ceramics and glass, etc. Particles made of inorganic materials such as those mentioned above may be used, and a mixture of these types of particles may be used. In addition, the above-mentioned chemical substances (e.g., formaldehyde) may be used in part or all of the filling material. A remover (e.g., chitosan) capable of removing aldehydes such as aldehyde may be added.

[0043] Alternatively, when the above-mentioned granular material is filled, the filling material is a material for extracting coffee. Alternatively, plant-based raw materials such as coffee grounds after brewing or used tea leaves after tea leaves are extracted may be used. These plant-based materials are porous and have a high deodorizing effect, so they are used as support parts with deodorizing effect. In addition, when using coffee grounds, the coffee grounds can be used as is. Because the particle size is small, it is recommended to use it in a ball-like form using starch or other materials. When using tea leaves, if the aerosol-forming substrate 23 is made of tea leaves, Both 23 and support member 30 can be made of the same material.

[0044] When flavor additives are added, for example, mint, cocoa, coffee, black tea extract, tea extract, etc. The flavor additive can be filled into the through hole 31a of the support member 30. The filling mode may be any of various modes as described below.

[0045] For example, when the flavor additive is enclosed in a capsule, the capsule is inserted into the through hole 31a. This allows smokers to press the capsule with their fingers to destroy it. This allows the flavor additive's aromatic components to volatilize at the desired timing. If the capsule has melting properties, it will melt when exposed to an aerosol and add flavor. The additive can be released to the outside. Further, when this capsule is a microcapsule, this micro capsule may be buried in the inner peripheral surface of the support member 30. Of course, the microcapsule may be disposed in the through-hole 31a. When the flavor additive is not encapsulated in the capsule, for example, the flavor additive may be impregnated in the inner peripheral surface of the support member 30.

[0046] Next, specific examples of the raw materials used as the aerosol forming base material 23 will be described. The air aerosol forming base material 23 is composed of any one or a combination of the following raw materials. It is.

[0047] The aerosol forming base material 23 uses a tobacco plant or a non-tobacco plant as a raw material. As the tobacco plant Examples include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. As the non-tobacco plant Examples include plants other than tobacco plants. Preferred parts of non-tobacco plants 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. It is.

[0048] In addition, the "plant" referred to in this specification means a group relative to animals, and in addition to organisms such as grass and trees that have roots and are fixed in place and alive, microalgae and seaweeds such as algae, and fungi such as mushrooms are also included. It is.

[0049] The aerosol forming base material 23 is, for example, a dried and pulverized non-tobacco plant, an aerosol former that generates an aerosol, microcrystalline cellulose, an additive that adds flavor, a preservative, a binder or a thickener, etc. are appropriately mixed, pulverized or classified to form a powder or granule, or a paste It is. It is formed into a strip shape. Further, after the aerosol-forming substrate 23 is formed into a sheet shape, it is cut to have a predetermined width and length and made into a strip shape or a rod shape.

[0050] 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 mustard tea, ezoukog tea, big leaf tobacco tea, ka kichodoshi tea, persimmon leaf tea, chamomile tea, camomile tea, kawaragemme 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, seisho tea, senburi tea, buckwheat tea, tara no ki tea, dandelion tea, sweet tea, dokudami tea, eucommia tea, adzuki bean tea, nira tea, nezumimochi tea, pearl barley tea, habu tea tea, loquat leaf tea, puer tea, red flower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea tea, eucalyptus tea, luohanguo tea, rooibos tea, bitter melon tea, etc. can be mentioned. Regarding these teas the tea leaves after drinking may be used. By using tea leaves or the like, expensive teas and the like can be reused and effectively utilized.

[0051] Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts and processed products can also be used. Examples of the form of the extract include liquid, water candy, powder, granule, solution, etc.

[0052] The aerosol former as a raw material of the aerosol-forming substrate 23 is glycerin, propylene Ethylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerol triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and the like can be mentioned. Among them However, glycerin and propylene glycol are preferred.

[0053] 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. .

[0054] 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 the solvent, a high-speed stirrer, a high-pressure homogenizer, or the like can be used.

[0055] Furthermore, a flavor additive for adding flavor as a raw material for the aerosol-forming substrate 23 is also preferably used. Examples of the flavor additive include peppermint, cocoa, coffee, tea extract, powder of catechin of tea extract, and the like. As preservatives, those used in foods are preferred. For example, sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, and the like can be mentioned.

[0056] Menthol and a water-insoluble crosslinked polymer (preferably poly vinylpyrrolidone) 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 can also be used. That's fine.

[0057] 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 can 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 can be arranged between the mouthpiece 40 and the heated body 20. That's fine too. When the flavor additive is encapsulated, the smoker can break the capsule by pressing it with a finger, and it becomes possible to volatilize the aromatic component of the flavor additive at a desired timing.

[0058]

[0058] Furthermore, when the flavor additive is encapsulated in microcapsules, for example, the microcapsules containing it can be provided on the heated body 20. Of course, the microcapsules can also be provided on the support member 30.

[0059] As the binder or thickener as the raw material of the aerosol-forming base material 23, gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, for example, cellulose binders such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose, for example, starch, al Organic acids such as ginic acid, sodium alginate, sodium carboxymethyl cellulose, polysaccharides such as conjugate base salts of organic acids such as carrageenan, agar, and pectin, and combinations thereof are exemplified.

[0060] (Method for producing aerosol-forming substrate) The method for producing the aforementioned aerosol-forming substrate 23 will be described separately for each step. The production process of the aerosol forming substrate 23 includes a drying and pulverizing step of drying and pulverizing the tobacco plant or non-tobacco plant as the main raw material, weighing, etc., a preparation step of performing pretreatment, weighing, etc. of other raw materials, and a mixing step of mixing the raw materials to form a composition, and a filler forming step of forming the composition. has. Yes.

[0061] In the drying and pulverizing step, 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.) as a composition, it is processed into a predetermined pulverized product. At this time, it is preferable to adjust the water 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 water content while avoiding the dissipation of the required flavor components. Furthermore, a sieving step for sieving the pulverized product can also be provided in the drying and pulverizing step, and it can be adjusted to the desired particle size and put into the mixing step.

[0062] In the preparation step, the raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and put into the mixing step.

[0063] ​​​In the mixing process, a normal mixer can be used. For example, the raw materials in the mixing tank are preferably mixed in such a form that a shearing force is applied while stirring with a stirring blade.

[0064] In the filler forming process, after forming the composition in which various raw materials are mixed into a thin sheet shape, it is cut to form the aerosol forming substrate 23 in the shape of a strip or a rod. 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 being pressed between the narrow rolls for compression and shearing 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.

[0065] Also, to make the aerosol forming substrate 23 in powder or granular form, it is preferable to appropriately grind or classify the above composition. The average particle size in the powder or granular aerosol forming substrate 23 is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less. This average particle size is, for example, determined by the sieving method described in JIS K 0069:1992. That is, this average particle size is 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 size at the integrated value of 50% in the particle size distribution determined by the laser diffraction / scattering method may be used as the average particle size.

[0066] In the filler forming process, other methods such as passing the composition through an orifice by pressure to form it, ​​​​​You may use the means. Also, in the filler forming step, if necessary, non-tobacco plants, aerosol formers, flavor additives such as binders or thickeners, preservatives may be further added, or water and the like may be added.

[0067] 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 , a rotary cutter of a rotary blade type or the like.

[0068] 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.

[0069] (Method of using a cartridge for a smoking device) The method of using the cartridge 1 for a smoking device will be described. FIG. 3 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 through-hole 31a of the support member 30 and the mouthpiece 40 in this order and enters the smoker's mouth.

[0070] According to the cigarette cartridge 1 according to the first embodiment configured as described above, the following effects can be achieved.

[0071] Since the inner diameter r1 of the support member 30 is smaller than the outer diameter D of the aerosol-forming substrate 23, the heating element 20 (aerosol-forming substrate 23) can be supported by the thickness portion between the inner diameter r1 and the outer diameter R1 of the support member 30. Therefore, movement of the heating element 20 (aerosol-forming substrate 23) toward the support member 30 can be suppressed.

[0072] Also, the dimension of the outer diameter R1 of the support member 30 and the dimension of the outer diameter D of the heating element 20 (aerosol-forming substrate 23) can be set to be the same. When both are the same, the entire first end portion 30a of the support member 30 can come into contact with the aerosol-forming substrate 23. Therefore, since the aerosol-forming substrate 23 can be sufficiently supported by the support member 30, movement of the heating element 20 (aerosol-forming substrate 23) toward the support member 30 can be further suppressed. Also, movement of the aerosol-forming substrate 23 between the first end portion 30a of the support member 30 and the exterior member 10 toward the support member 30 side can be prevented.

[0073] Also, since the shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b, the shape of the through-hole 31a of the support member 30 does not become uniform along the central axis C1. Therefore, even if a part of the aerosol-forming substrate 23 enters the through-hole 31a, it is difficult for it to move inside.

[0074] Furthermore, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, and the diameter of the through hole 31a of the support member 30 is smaller at the second end portion 30b than at the first end portion 30a. Therefore, the movement of the aerosol forming base material 23 that has entered the inside of the through hole 31a can be made more difficult. Moreover, since the support member 30 is formed such that the inner diameter gradually decreases from the first end portion 30a toward the second end portion 30b, the aerosol forming base material 23 that has entered the through hole 31a of the support member 30 collides with the inner peripheral portion of the through hole 31a. Moreover, the escape space for the collided aerosol forming base material 23 is restricted. Therefore, the movement of the aerosol forming base material 23 that has entered the through hole 31a can be prevented.

[0075] Also, since the support member 30 is formed by winding the sheet-like member 31, friction is likely to occur between the aerosol forming base material 23 and the sheet-like member 31. Therefore, the movement of the aerosol forming base material 23 that has entered the through hole 31a of the support member 30 can be further prevented.

[0076] Furthermore, since the support member 30 has a simple configuration formed by winding the sheet-like member 31 into a cylindrical shape, the manufacturing cost can be suppressed.

[0077]

[0078] (Second Embodiment) Next, a cigarette holder cartridge according to the second embodiment will be described. The cigarette holder cartridge 2 according to the second embodiment has basically the same configuration as the cigarette holder cartridge 1 according to the first embodiment, except that the support member 30 is composed of a resin molded product 32 having a frustum of a cone shape. Therefore, in the following description, the description will focus on this difference, and the description overlapping with the first embodiment will be omitted.

[0079] Figure 4 is a cross-sectional view of the cartridge 2 for a smoking device according to the second embodiment. As shown in Figure 4 , the support member 30 (resin molded product 32) is arranged such that its lower bottom surface faces the aerosol forming substrate 23 , and its upper bottom surface faces the mouthpiece 40. The shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b. The support member 30 has a frustum -shaped through hole 32a inside it, and the inner diameter r1 of the support member 30 is larger than the inner diameter r2. Also, the outer diameter R1 of the first end portion 30a of the support member 30 is larger than the outer diameter R2 of the second end portion 30b. Fur thermore, a plurality of recesses 32c are formed on the outer peripheral surface 32b of the support member 30. Note that instead of the plurality of recesses 32c, a plurality of protrusions may be formed.

[0080] Next, referring to Figure 5, the relationship between the outer diameter R1 and the inner diameter r1 of the support member 30, and the outer diameter D of the aerosol forming base material 23 will be described. The left figure in Figure 5 is a longitudinal cross-section of the aerosol forming substrate 23 viewed from the support member 30 side of the cross-section obtained by cutting the cartridge 2 for a smoking device shown in Figure 4 along the V-V line, and the right figure in Figure 5 is a longitudinal cross-section of the support member 30 viewed from the aerosol forming substrate 23 side of the same cross-section .

[0081] As shown in Figure 5, both the outer diameter R1 of the support member 30 (resin molded product 32) and the outer diameter D of the aerosol forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 is the length between L2 and L3, that is, from the outer diameter R1 (= outer diameter D) of the support member 30 excluding the thickness (2Δr) of the thick portion of the support member 30.

[0082] According to the cartridge 2 for a smoking device according to the second embodiment configured as described above, as described above The same effects as those of the first embodiment can be achieved. Further, according to the second embodiment, since the outer diameter R1 of the support member 30 is larger than the outer diameter R2, the support member 30 can contact one end portion 23a of the aerosol-forming substrate 23 over a large area. In particular, since the support member 30 is formed of a frustum-shaped resin molded article 32, one end portion 23a of the aerosol-forming substrate 23 can be reliably supported by the thick portion thereof, and the movement of the object to be heated 20 (aerosol-forming substrate 23) toward the support member 30 side can be reliably suppressed.

[0083] Further, since a plurality of concave portions 32c are formed on the outer peripheral surface 32b of the support member 30, it becomes easier to grip the support member 30 during the manufacture of the cartridge 2 for a smoking device, and the manufacture can be made more efficient. Of course, instead of the plurality of concave portions 32c, a plurality of convex portions may be formed, and the same operational effects can be achieved in that case.

[0084] In FIG. 4, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, but the configuration is not limited to this. As long as one end portion 23a of the aerosol-forming substrate 23 can be supported by the thick portion of the support member 30 (resin molded article 32), the inner diameter r2 of the support member 30 may be equal to the inner diameter r1 or larger than the inner diameter r1. When the inner diameter r2 of the support member 30 is equal to the inner diameter r1, the inner diameter of the support member 30 may be formed to be uniform from the first end portion 30a to the second end portion 30b. When the inner diameter r2 of the support member 30 is larger than the inner diameter r1, the inner diameter of the support member 30 may increase on the way from the first end portion 30a to the second end portion 30b, or may gradually increase from the first end portion 30a to the second end portion 30b. Further, when the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and when the inner diameter r2 of the support member 30 is larger than the inner diameter r1 ​​​​​​​​​​​In any of these cases, the outer diameters R1 and R2 of the support member 30 may be made equal.

[0085] (Third Embodiment) Next, a cartridge for a smoking implement according to the third embodiment will be described. The cartridge 3 for a smoking implement according to the third embodiment comprises a support member 30 formed of a cylindrical body formed by winding a sheet-like member 33, and is different from the first embodiment in that a plurality (four in this embodiment) of ridge portions 33b are provided on the inner peripheral surface 33a thereof.

[0086] The four ridge portions 33b are each formed by forming an incision obliquely with respect to the longitudinal direction in a part (four locations) of the outer peripheral surface 33c of the sheet-like member 33, and folding the portion where the incision is formed inward. The four ridge portions 33b extend along the central axis C1 and are arranged at equal intervals (90-degree intervals) in the circumferential direction of the support member 30 (see FIG. 7 described later). Each ridge portion 33b is formed such that the width W1 on the first end portion 30a side of the support member 30 is narrower than the width W2 on the second end portion 30b side. Also, the width of each ridge portion 33b gradually increases from the first end portion 30a to the second end portion 30b of the support member 30. Note that the shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b.

[0087] The size of the width W1 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm, more preferably in the range of 1.0 mm to 3.0 mm. If the size of the width W1 is set to 0.5 mm or more, it becomes possible to secure the minimum width of the support member 30 necessary for supporting the heated body 20. Also, if the size of the width W1 is set to 1.0 mm or more, it becomes possible to secure a sufficient width of the support member 30 for supporting the heated body 20. Furthermore, if the size of the width W1 is 4.0 m ​​​​​If it is set to m or less, in order for the aerosol to flow through the region within the circle C indicated by the dotted line in FIG. 7, the minimum required channel size can be ensured. Also, if the size of the width W1 is set to 3.0 mm or less then, in order for the aerosol to flow through the region within the circle C indicated by the dotted line in FIG. 7, a sufficient channel size can be ensured.

[0088] Also, the size of the width W2 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm more preferably in the range of 1.25 mm to 3.25 mm. If the size of the width W2 is set to 0 .5 mm or more, the minimum required width of the support member 30 for supporting the heated body 20 can be ensured. Also, if the size of the width W2 is set to 1.25 mm or more, a sufficient width of the support member 30 for supporting the heated body 20 can be ensured. Further, if the size of the width W2 is set to 4.0 mm or less, in order for the aerosol to flow through the region within the circle C' indicated by the dotted line in FIG. 7 the minimum required channel size can be ensured. Also, if the size of the width W2 is set to 3.2 5 mm or less, a sufficient channel size for the aerosol to flow through the region within the circle C' indicated by the dotted line in FIG. 7 can be ensured.

[0089] When manufacturing the support member 30, by appropriately selecting the sizes of the widths W1 and W2 within the above ranges the channel size of the support member 30 can be adjusted. Also, the support strength of the heated body 20 ( the aerosol-forming substrate 23) by the support member 30 can be adjusted to appropriately support the heated body 20 according to the material of the aerosol-forming substrate 23.

[0090] Hereinafter, for convenience of explanation, among the four ridge portions 33b, the ridge portion 33b formed at the top of the support member 30 (the sheet-like portion material 33) is referred to as the "first ridge portion 331b", and this first​​​ The protruding strip portion 33b formed at a position rotated 90 degrees clockwise with respect to the strip portion 331b is sequentially referred to as the "second protruding strip portion 332b", the "third protruding strip portion 333b", and the "fourth protruding strip portion 334 b".

[0091] Next, with reference to FIG. 7, the relationship between the outer diameter R and the inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 7 is a longitudinal section of the aerosol-forming substrate 23 viewed from the support member 30 side of the cross-section obtained by cutting the cigarette lighter 3 shown in FIG. 6 along the line VII-VII, and the right diagram in FIG. 7 is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side of the same cross-section. In FIG. 7, L2 is a straight line passing through the tip of the first protruding strip portion 331b at the first end portion 30a of the support member 30, and L3 is a straight line passing through the tip of the third protruding strip portion 33b.

As shown in FIG. 7, both the outer diameter R of the support member 30 (sheet-like member 33) and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 is the length between L2 and L3 corresponding to the diameter of the circle C, that is, the outer diameter R (= outer diameter D) of the support member 30 minus the width (W1) of the first protruding strip portion 331b and the width (W 1) of the third protruding strip portion 333b. In the right diagram of FIG. 7, the portion protruding inside the circle C in each protruding strip portion 33b is a portion that widens from the first end portion 30a to the second end portion 30b of the support member 30.

Further, according to the third embodiment, since the support member 30 has a plurality of protruding ridges 33b extending along the central axis C1 on its inner peripheral surface 33a, the aerosol forming base material 23 can be firmly supported on the first end portion 30a side of the support member 30. Moreover, since the plurality of protruding ridges 33b are arranged at equal intervals in the circumferential direction of the support member 30, the aerosol forming base material 23 can be supported in a well-balanced manner. Also, the support member 30 is formed by winding a sheet-like member 33, and the plurality of protruding ridges 33b are each formed by bending a part of the outer peripheral surface 33c of the sheet-like member 33 inward, so that the support member 30 can have a simple configuration and the manufacturing cost can be suppressed. Incidentally, the support member 30 may be configured to be made of a resin molded product as in the second embodiment. In this case, the plurality of protruding ridges may be formed so as to protrude from the inner peripheral surface of the support member 30 by resin molding. Also, the number of the plurality of protruding ridges 33b is not limited to four, and may be one or more. In addition, in FIG. 6, the width W1 of the support member 30 is formed to be narrower than the width W2, but the present invention is not limited to this configuration. As long as one end portion 23a of the aerosol forming base material 23 can be supported by the plurality of protruding ridges 33b of the support member 30, the width W2 of the support member 30 may be equal to or wider than the width W1. When the width W2 of the support member 30 is equal to the width W1, the width from the first end portion 30a to the second end portion 30b of the support member 30 is from the first end portion 30a to the second

Further, when the width W2 of the support member 30 is larger than the width W1, the width from the first end portion 30a to the second end portion 30b of the support member 30 may increase in the middle of going from the first end portion 30a to the second end portion 30b, or may gradually increase from the first end portion 30a toward the second end portion 30b.

[0097] (Fourth Embodiment) Next, a cartridge for a smoking device according to the fourth embodiment will be described. The cartridge 4 for a smoking device according to the fourth embodiment is different from the first embodiment in that a blocking portion 34 for blocking the axial movement of the heating body 20 (the aerosol forming base material 23) is formed at the first end portion 30a of the support member 30.

[0098] The blocking portion 34 is composed of a plurality (six in this embodiment) of protruding portions 34a protruding from the inner peripheral surface toward the central axis C1 at the first end portion 30a of the support member 30. The support member 30 has a cylindrical portion 35 arranged along the central axis C1, and the six protruding portions 34a are provided on the side of the aerosol forming base material 23 of the cylindrical portion 35. These protruding portions 34a are arranged at equal intervals (60-degree intervals) in the circumferential direction so as to face one end portion 23a of the aerosol forming base material 23.

[0100] Next, with reference to FIG. 9, the relationship between the outer diameter R and the inner diameter r1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 9 is a longitudinal section of the aerosol-forming substrate 23 viewed from the support member 30 side of a cross-section obtained by cutting the trigger 4 for the smoking device shown in FIG. 8 along the line IX-IX, and the right diagram in FIG. 9 is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side of the same cross-section. In FIG. 9, L2 is a straight line passing through the tip of the first protrusion 341a of the support member 30, and L3 is a straight line passing through the tip of the fourth protrusion 344a of the support member 30. Also, in the right diagram of FIG. 9, the circle C' indicated by the dotted line is drawn by connecting the tips of the first to sixth protrusions 341a to 346a in an arc shape, and its diameter represents the inner diameter r1 of the support member 30. The size of this inner diameter r1 is, for example, 6.5 mm or less. As shown in FIG. 9, both the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3, which corresponds to the diameter of the circle C', that is, from the outer diameter R (= outer diameter D) of the support member 30 minus the length corresponding to the protrusion amount (T) of the first protrusion 341a and the protrusion amount (T) of the fourth protrusion 344a. The size of the protrusion amount (T) is preferably in the range of, for example, 0.5 mm to 3.5 mm, and more preferably in the range of 1.0 mm to 3.25 mm. If the size of the protrusion amount (T) is set to 0.5 mm or more, it becomes possible to secure the minimum necessary protrusion amount of the support member 30 for supporting the heating element 20. Also, when the size of the protrusion amount (T) is 1.0 m m to the sixth protrusions 341a to 346a in an arc shape, and its diameter represents the inner diameter r1 of the support member 30. The size of this inner diameter r1 is, for example, 6.5 mm or less.

[0101] As shown in FIG. 9, both the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3, which corresponds to the diameter of the circle C', that is, from the outer diameter R (= outer diameter D) of the support member 30 minus the length corresponding to the protrusion amount (T) of the first protrusion 341a and the protrusion amount (T) of the fourth protrusion 344a. The size of the protrusion amount (T) is preferably in the range of, for example, 0.5 mm to 3.5 mm, and more preferably in the range of 1.0 mm to 3.25 mm. If the size of the protrusion amount (T) is set to 0.5 mm or more, it becomes possible to secure the minimum necessary protrusion amount of the support member 30 for supporting the heating element 20. Also, when the size of the protrusion amount (T) is 1.0 m to the sixth protrusions 341a to 346a in an arc shape, and its diameter represents the inner diameter r1 of the support member 30. The size of this inner diameter r1 is, for example, 6.5 mm or less. mm, and more preferably in the range of 1.0 mm to 3.25 mm. The protrusion quantity (T) is set to 0.5 mm or more, it is possible to ensure the minimum necessary protrusion amount of the support member 30 for supporting the heating element 20. Also, when the size of the protrusion amount (T) is 1.0 m quantity (T) is set to 0.5 mm or more, it is possible to ensure the minimum necessary protrusion amount of the support member 30 for supporting the heating element 20. Also, when the size of the protrusion amount (T) is 1.0 m If it is set to m or more, a sufficient protruding amount of the support member 30 for supporting the object to be heated 20 can be ensured. Furthermore, if the size of the protruding amount (T) is set to 3.5 mm or less, the minimum necessary size of the flow path for the aerosol to flow through the region within the circle C' shown by the dotted line in FIG. 9 can be ensured. If the size of the protruding amount (T) is set to 3.25 mm or less, a sufficient size of the flow path for the aerosol to flow through the region within the circle C' shown by the dotted line in FIG. 9 can be ensured. .

[0102] When manufacturing the support member 30, by appropriately selecting the size of the protruding amount (T) within the above range, the size of the flow path on the first end portion 30a side of the support member 30 can be adjusted. Also, the support strength of the object to be heated 20 (the aerosol-forming substrate 23) by the support member 30 can be adjusted, and the object to be heated 20 can be appropriately supported according to the material of the aerosol-forming substrate 23.

[0103] According to the smoking implement cartridge 4 according to the fourth embodiment configured as described above, the same effects as those of the first embodiment described above can be achieved. Furthermore, according to the fourth embodiment, since the blocking portion 34 that blocks the axial movement of the object to be heated 20 (the aerosol-forming substrate 23) is formed at the first end portion 30a of the support member 30, the movement of the object to be heated 20 (the aerosol-forming substrate 23) toward the support member 30 side can be reliably suppressed. Moreover, since the six protruding portions 34a are provided along the circumferential direction of the support member 30, the outer peripheral portion and the portion within a predetermined range from the outer peripheral portion of the aerosol-forming substrate 23 can be reliably supported.

[0104] Also, since the six protruding portions 34a are arranged at equal intervals in the circumferential direction, the aerosol-forming substrate 23 can be supported in a well-balanced manner.

[0105] In addition, the blocking portion 34 (plurality of protruding portions 34a) is formed only on the first end portion 30a of the support member 30. Therefore, the support member 30 can be made to have a simple structure, and the manufacturing cost can be reduced. .

[0106] In FIG. 8, the blocking portion 34 is formed only on the first end portion 30a side of the support member 30. However, it may also be formed on the second end 30b side. In this case, The protruding amount is equal to the protruding amount (T) of the blocking portion 34 on the first end portion 30a side, or In this case, the blocking portion 34 on the first end 30a side and the blocking portion 35 on the second end 30b side may be different from the blocking portion 35 on the first end 30a side. The blocking portion on the second end 30b side may be formed so as to be connected to the blocking portion on the second end 30b side. When the protruding amount of the blocking portion 34 on the first end 30a side is equal to the protruding amount (T) of the blocking portion 34 on the first end 30a side, The protruding amount of the blocking portion from the first end 30a to the second end 30b is The amount of protrusion of the blocking portion on the second end 30b side may be uniform. When the protruding amount (T) of the blocking portion 34 on the first end portion 30a side is different from that of the blocking portion 34 on the second end portion 30a side, The protrusion amount of the blocking portion reaching the end 30b side is The size may vary from the first end 30a to the second end 30b. It's okay if it gets bigger.

[0107] Fifth embodiment Next, a cartridge for a smoking article according to a fifth embodiment will be described. The cartridge 5 for a smoking article is different from the fourth embodiment in that it has a mesh member 34b as the blocking portion 34. Different from the form.

[0108] The mesh member 34b covers the first end portion 30a of the support member 30 (cylindrical portion 35), and the shape of the first end portion 30a of the support member 30 is different from the shape of the second end portion 30b. The mesh member 34b is made of, for example, a wire mesh member, and the size of its mesh is set to a size through which the aerosol-forming substrate 2 3 cannot pass. Note that the material of the mesh member 34b may be any material with relatively high heat resistance. Also, it can be substituted with a punching plate or the like.

[0109] Next, with reference to FIG. 11, the relationship between the outer diameter R and the inner diameter r1 of the support member 30, and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 11 is a longitudinal section of the aerosol -forming substrate 23 viewed from the support member 30 side of a cross section obtained by cutting the cigarette cartridge 5 for a smoking device shown in FIG. 10 along the line XI-XI, and the right diagram in FIG. 11 is a longitudinal section of the support member 30 viewed from the aerosol -forming substrate 23 side of the same cross section.

[0110] As shown in FIG. 11, both the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3, and corresponds to the length obtained by excluding the length (Δr) between L1 and L2 and the length (Δr) between L4 and L5 from the outer diameter R (= outer diameter D) of the support member 30, that is, the thickness (2Δr ) of the cylindrical portion 35.

[0111] According to the cigarette cartridge 5 for a smoking device according to the fifth embodiment configured as described above, the same effects as those of the first embodiment described above can be achieved. Furthermore, according to the fifth embodiment, the mesh member 34b as the blocking portion 34 is provided so as to cover the first end portion 30a of the support member. ​​Therefore, it can support the entire surface of the aerosol-forming substrate 23 and reliably prevent the heated object 20 (aerosol-forming substrate 23) from moving toward the support member 30 side.

[0112] In addition, since it is only necessary to form the blocking portion 34 (mesh-like member 34b) only at the first end portion 30a of the support member 30, the support member 30 can have a simple configuration, and the manufacturing cost can be suppressed.

[0113] In FIG. 10, the mesh-like member 34b is formed only on the side of the first end portion 30a of the support member 30, but it may also be formed on the side of the second end portion 30b. In this case, the diameter of the mesh-like member on the side of the second end portion 30b (inner diameter r2 of the support member 30) is equal to the diameter of the mesh-like member 34b on the side of the first end portion 30a (inner diameter r1 of the support member 30), or may be larger than the diameter of this mesh-like member 34b. Also, when the diameter of the mesh-like member on the side of the second end portion 30b is equal to the diameter of the mesh-like member 34b on the side of the first end portion 30a, the second end portion 30b of the support member 30 (cylindrical portion 35) shown in FIG. 10 may be covered with the mesh-like member. Also, when the diameter of the mesh-like member on the side of the second end portion 30b is larger than the diameter of the mesh-like member 34b on the side of the first end portion 30a, the amount of protrusion inward of the cylindrical portion 35 may change in size on the way from the first end portion 30a to the second end portion 30b, or may gradually increase from the first end portion 30a toward the second end portion 30b. Furthermore, in this case, a configuration in which the cylindrical portion 35 is filled with the mesh-like member may also be used.

[0114] (Sixth Embodiment) Next, a cartridge for a smoking device according to the sixth embodiment will be described. The cartridge 6 for a smoking device according to the sixth embodiment differs from the fourth embodiment in that the blocking portion 36 has a saw blade shape.

[0115] The blocking part 36 is composed of a plurality (eight in this embodiment) of protruding parts 36a that protrude from the inner peripheral surface toward the central axis C1 at the first end part 30a of the support member 30. The tip of each protruding part 36a is sharp, and the plurality of protruding parts 36a are arranged at equal intervals (at 45-degree intervals) in the circumferential direction on the aerosol-forming substrate 23 side of the cylindrical part 35 of the support member 30. As a result, the blocking part 36 has a saw blade shape. Note that the shape of the first end part 30a of the support member 30 is different from the shape of the second end part 30b. In the following, for convenience of explanation, among the eight protruding parts 36a, the protruding part 36a formed at the top of the support member 30 (cylindrical part 35) is referred to as the "first protruding part 361a", and the protruding parts 36a formed at positions rotated by 45 degrees each clockwise with reference to this first protruding part 361a are sequentially referred to as the "second protruding part 362a", the "third protruding part 363a", the "fourth protruding part 364a", the "fifth protruding part 365a", the "sixth protruding part 366a", the "seventh protruding part 367a", and the "eighth

[0116] protruding part 368a". Next, with reference to FIG. 13, the relationship between the outer diameter R and the inner diameter r1 of the support member 30, and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 13 is a longitudinal section of the aerosol-forming substrate 23 viewed from the support member 30 side of the cross-section obtained by cutting the cartridge 6 for the smoking device shown in FIG. 12 along the XIII-XIII line, and the right diagram in FIG. 13 is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side of the same cross-section. In FIG. 13, L2 is a straight line passing through the tip of the first protruding part 361a of the support member 30, and L3 is the first of the support member 30. protruding part 36a formed at a position rotated by 45 degrees each clockwise with reference to this first protruding part 361a are sequentially referred to as the "second protruding part 362a", the "third protruding part 363a", the "fourth protruding part 364a", the "fifth protruding part 365a", the "sixth protruding part 366a", the "seventh protruding part 367a", and the "eighth

[0117] Next, with reference to FIG. 13, the relationship between the outer diameter R and the inner diameter r1 of the support member 30, and the outer diameter D of the aerosol-forming substrate 23 will be described. The left diagram in FIG. 13 is a longitudinal section of the aerosol-forming substrate 23 viewed from the support member 30 side of the cross-section obtained by cutting the cartridge 6 for the smoking device shown in FIG. 12 along the XIII-XIII line, and the right diagram in FIG. 13 is a longitudinal section of the support member 30 viewed from the aerosol-forming substrate 23 side of the same cross-section. In FIG. 13, L2 is a straight line passing through the tip of the first protruding part 361a of the support member 30, and L3 is the first protruding part 36a formed at a position rotated by 45 degrees each clockwise with reference to this first protruding part 361a are sequentially referred to as the "second protruding part 362a", the "third protruding part 363a", the "fourth protruding part 364a", the "fifth protruding part 365a", the "sixth protruding part 366a", the "seventh protruding part 367a", and the "eighth protruding part 368a". protruding part 36a formed at a position rotated by 45 degrees each clockwise with reference to this first protruding part 361a are sequentially It is a straight line passing through the tip of the protrusion 365a. Also, in the right figure of FIG. 13, it is indicated by a dotted line The circle C´ is drawn by connecting the tips of the first to eighth protrusions 361a to 368a in an arc shape, and its diameter represents the inner diameter r1 of the support member 30.

[0118] As shown in FIG. 13, both the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 is the length between L2 and L3 corresponding to the diameter of the circle C´, that is, the outer diameter R (= outer diameter D) of the support member 30 minus the lengths corresponding to the protrusion amount (T) of the first protrusion 361a and the protrusion amount (T) of the fifth protrusion 365a. It corresponds to the value excluding the lengths corresponding to the protrusion amounts (T) of the first protrusion 361a and the fifth protrusion 365a.

[0119] According to the cigarette cartridge 6 according to the sixth embodiment configured as described above, the same effects as those of the first embodiment and the fourth embodiment described above can be achieved. Furthermore, according to the sixth embodiment, since the plurality of protrusions 36a of the blocking portion 36 have a saw blade shape, even if a part of the aerosol-forming substrate 23 enters the inside of the support member 30, the aerosol-forming substrate 23 is caught by the sharp tips of the plurality of protrusions 36a, making it difficult to move. Therefore, the movement of the heated body 20 (aerosol-forming substrate 23) toward the support member 30 can be reliably suppressed.

[0120] Also, since it is only necessary to form the blocking portion 36 (a plurality of protrusions 36a) only at the first end portion 30a of the support member 30, the support member 30 can have a simple configuration, and the manufacturing cost can be suppressed. .

[0121] In FIG. 12, the blocking portion 36 is formed only on the side of the first end portion 30a of the support member 30. ​​​​​​However, it may also be formed on the second end portion 30b side. In this case, the protruding amount of the blocking portion on the second end portion 30b side is equal to the protruding amount (T) of the blocking portion 36 on the first end portion 30a side, or may be formed to be different from this protruding amount (T). At this time, the blocking portion 34 on the first end portion 30a side and the blocking portion on the second end portion 30b side may be formed to be connected. When the protruding amount of the blocking portion on the second end portion 30b side is equal to the protruding amount (T) of the blocking portion 36 on the first end portion 30a side, the protruding amount of the blocking portion from the first end portion 30a side to the second end portion 30b side may be formed to be uniform from the first end portion 30a to the second end portion 30b. Also, when the protruding amount of the blocking portion on the second end portion 30b side is different from the protruding amount (T) of the blocking portion 36 on the first end portion 30a side, the protruding amount of the blocking portion from the first end portion 30a side to the second end portion 30b side may change in size during the process from the first end portion 30a to the second end portion 30b, or may gradually increase from the first end portion 30a to the second end portion 30b.

[0122] Note that the present invention is not limited to the above-described 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-described embodiments show preferred examples, but those skilled in the art can realize various alternative examples, correction examples, modification examples, or improvement examples from the content disclosed in this specification, and these are included in the technical scope described in the appended claims.

[0123] For example, in the present invention, it is not necessarily essential to provide the mouthpiece 40 of the above-described first to sixth embodiments. It can be appropriately determined according to the design specifications of the cartridge for the smoking device. ​​​​​​​​​​​If the axial length of the support member 30 is extended, for example, about 2.5 times the axial length of the aerosol-forming substrate 23, and the aerosol passing through the support member 30 can be sufficiently cooled, the mouthpiece 40 may not be provided. Also, for example, in the smoking implement cartridge 1 according to the first embodiment, the support member 30 may be constituted by a resin molded product, and convex portions or concave portions may be formed on the outer peripheral surface of this resin molded product.

[0124] Further, in the first embodiment, a shaft portion extending along the central axis C1 may be provided in the through hole 31a of the support member 30. In this case, by providing a holding member for holding the shaft portion from the inner peripheral surface of the through hole 31a, the posture of the shaft portion may be maintained.

[0125] Furthermore, in the above embodiment, if the support member 30 is formed in a cylindrical shape, its shape is not limited. For example, a cylindrical body having a triangular, quadrilateral, or other polygonal cross-section may be used.

[0126] Also, in the second to sixth embodiments, similar to the first embodiment, the outer diameter R (R1) of the support member may be smaller than the outer diameter D of the aerosol-forming substrate 23.
