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 implement cartridge 1 according to a first embodiment of the present invention. As shown in FIG. 1 the smoking implement cartridge 1 according to the first embodiment includes a heating element 20, a support member 3 0, and a mouthpiece 40. The heating element 20, the support member 30, and the mouthpiece 40 are arranged side by side on the central axis C1. Then, the heating element 20, the support member 30, and the mouth 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 implement 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 heating element 20 has a length of from 10 to 25 mm Of course, the smoking implement cartridge 1 may be formed with other dimensions.

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

[0014] The object to be heated 20 includes an aerosol-forming substrate 23 that generates an aerosol when heated. The heated object 20 includes any form of aerosol-forming substrate 23. As for the form of the aerosol-forming substrate 23, for example, strip-shaped, rod-shaped, granular members described later are highly A form filled with a certain density or low density, consisting of multiple strip-shaped, rod-shaped, granular, or other components in a predetermined gap. Examples include a form provided via an intermediary, and a form consisting of multiple capsules containing flavor additives. Of course, in the form of the aerosol-forming substrate 23 described below, which is not listed above. That's good too.

[0015] Furthermore, the aerosol-forming substrate 23 contained in the heated object 20 is used in the smoking device cartridge 1. Even if the filling state inside the outer material 10 changes depending on the orientation, the outer diameter of the heated object 20 The size of D is always constant, and in this embodiment, as described above, the inner diameter of the exterior member 10 is It is equal in size.

[0016] Furthermore, in the above case, the heated object 20 (aerosol-forming substrate 23) directly contacts the exterior member 10 The case where the heated object 20 is covered by the aerosol-forming substrate 23 will be described later. In the case of a configuration in which the heated object 20 is wrapped with a sheet-like packaging material, the outer diameter D of the heated object 20 is This will be equal to the outer diameter of the packaging material. For example, the strip-shaped, rod-shaped, and granular aero packs mentioned above. When the sol-forming substrate 23 is filled into the packaging material at a low density, the aerosol-forming substrate 23 may move inside the packaging material, but the shape of the packaging material itself remains unchanged. Therefore, the outer diameter D of the heated object 20 remains unchanged.

[0017] Furthermore, the support member 30 is the packing density of the aerosol-forming substrate 23 that constitutes the heated object 20. Regardless, as long as it has the function of preventing the movement of the heated object 20, the "support member" of the present invention This is included in the above-mentioned configuration of the heated object 20 and the support member 30. It falls within the technical scope of the present invention. For example, if the object to be heated 20 is a strip-shaped, rod-shaped, granular, or granular material. If the aerosol-forming substrate 23 is filled at a low density, the smoker will use the smoking device 7 By inserting the needle-shaped or blade-shaped heating element 75 into the aerosol-forming substrate 23, Even if the allosol-forming substrate 23 is pushed toward the support member 30, the support member 30 will not allow air to pass through. This prevents the rosol-forming substrate 23 from moving toward the support member 30.

[0018] The aerosol-forming substrate 23 is wound by the outer material 10 to form a cylindrical shape. The outer diameter D of the sol-forming substrate 23 is equal to the outer diameter D of the heated object 20, and along the central axis C1 The value remains roughly constant. The size of this outer diameter D is, for example, 4.0 mm to 7.5 mm. The range is preferred, and more preferably, in the range of 5.0 mm to 7.0 mm. Setting the gap to 4.0 mm or more will enable the generation of the minimum necessary amount of aerosol. By setting the outer diameter D to 5.0 mm or larger, it becomes possible to generate a sufficient amount of aerosol. Furthermore, if the outer diameter D is set to 7.5 mm or less, the heated element 20 will be connected to the smoking device 70. This makes it possible to attach it. Also, if the outer diameter D is set to 7.0 mm or less, the smoking device 70 can be attached. The object to be heated 20 can be easily attached.

[0019] Furthermore, both ends of the aerosol-forming substrate 23 are not covered by a lid member (e.g., paper). , exposed. One end 23a of the two ends of the aerosol-forming substrate 23 is a support member The side facing 30, and the other end 23b is the side that is inserted into the insertion part 72 of the smoking device 70. Here, the term "end" as used in this specification refers to the end face and the area along the central axis C1 from the end face. This includes the portion inside a defined range. The object to be heated 20 is, for example, an aerosol-forming substrate 23. It may also be constructed by wrapping it with a sheet-like packaging material made of paper, or as an aerosol-forming substrate. Alternatively, the 23 may be covered with a lid member.

[0020] The aerosol-forming substrate 23 is made from tobacco plants or non-tobacco plants, as will be described in more detail later. It is composed of smoking materials. The aerosol-forming substrate 23 is, for example, made by bundling strip-shaped members. It is constructed in such a way that its axial direction (longitudinal direction) is aligned with the central axis C1.

[0021] When the aerosol-forming substrate 23 is made of strip-shaped members, the cross section perpendicular to the central axis C1 is approximately It is rectangular in shape, and the ratio of the long side to the short side of its cross-section is, for example, in the range of 1:1 to 30:1. Preferably, the length of the long side is in the range of 0.1 mm to 7.5 mm, and more preferably... More specifically, it is in the range of 0.1 mm to 3.0 mm. The length of the shorter side is 0.1 mm to 1.0 mm. A range of 0.1 mm to 0.5 mm is preferred, and more preferably a range of 0.1 mm to 0.5 mm. The length of the rosol-forming substrate 23 is preferably approximately the same as the length of the heated object 20. The length of the forming substrate is preferably in the range of 10 mm to 25 mm, and more preferably 10 mm to The range is 20 mm. An example of the dimensions of such an aerosol-forming substrate 23 is the length The sides are 1.5 mm, the shorter 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, a rod-shaped member. It may be a powder or paste-like material, or it may be an aerosol. The forming substrate 23 is a combination of strip-shaped members and granular members, and strip-shaped members and rod-shaped members. A combination of a rod-shaped member and a granular member, or a combination of a strip-shaped member and a rod-shaped member. The configuration may consist of a combination of a solid component and a granular component. In these cases, each component It is preferable to use different ingredients, at least in part, as this improves the aroma and flavor.

[0023] The mouthpiece 40 is the part that makes up the mouthpiece of the smoking device cartridge 1, and is made of, for example, paper. It is formed using the like. Also, the mouthpiece 40 has a diameter of, for example, 6.5 mm to 7.5 mm. The length along the central axis C1 is formed to be 50 mm or less. Furthermore, the mouthpiece 40 For example, a sheet-like material made of paper may be rolled up to form a cylindrical shape, or fine particles may be removed. It may include cellulose acetate filters, etc., but not the water produced in the heated body 20. Some of the fine particles in the vapor and aerosol are filtered out by the filter of this mouthpiece 40. It can be done.

[0024] The support member 30 is formed by winding a sheet-like member 31, for example, made of paper, once or multiple times to form a cylindrical shape. The support member 30 is formed such that its axial direction is aligned with the central axis C1 and the aerosol forming group It is positioned between material 23 and mouthpiece 40. The support member 30 is, for example, on the central axis C1. The length along it is formed to be 50 mm or less. This is one of the ends of the support member 30. The first end portion 30a is the side facing one end portion 23a of the aerosol-forming substrate 23, and the other end portion is the side facing the other end portion 23a. The second end 30b, which is the end of one side, is on the opposite side from the first end 30a, that is, the mouthpiece 40. This is the opposing side. The first end portion 30a of the support member 30 is in contact with the aerosol-forming substrate 23. The second end portion 30b contacts the mouthpiece 40. Then, the inside of the support member 30 is aerozo A vehicle passes through.

[0025] The support member 30 has a frustoconical through-hole 31a through which an aerosol passes, The shape of the first end 30a and the shape of the second end 30b are different. Specifically, the support member The sheet-like member 31 constituting 30 has a smaller diameter at the second end 30b than at the first end 30a. By winding it in a way that makes it thin, the inner diameter r1 of the first end 30a becomes the inner diameter r2 of the second end 30b. It is larger than that. Also, the inner diameter of the support member 30 is from the first end 30a to the second end 30 It gradually decreases as it approaches b. Also, the outer part of the first end 30a of the support member 30 The diameter R1 is larger than the outer diameter R2 of the second end portion 30b.

[0026] The inner diameter r1 of the support member 30 is preferably in the range of 0.5 mm to 6.5 mm. More preferably, the size is in the range of 1.0 mm to 5.0 mm. The size of the inner diameter r1 is 0.5 mm. If set to m or higher, the minimum required amount of aerosol is needed for it to flow through the through-hole 31a of the support member 30. This makes it possible to secure the necessary flow path size. Also, the inner diameter r1 can be set to 1.0 mm or larger. This ensures that the flow path is large enough for the aerosol to flow through the through-hole 31a of the support member 30. This makes it possible to maintain the temperature. Furthermore, if the inner diameter r1 is set to 6.5 mm or less, the heated object 20 This makes it possible to secure the minimum thickness of the support member 30 necessary to support it. Also, the inner diameter r1 If the size is set to 5.0 mm or less, a sufficient support member 3 will be provided to support the object to be heated 20. This makes it possible to secure a thickness of 0.

[0027] Furthermore, the inner diameter r2 of the support member 30 is preferably in the range of 0.5 mm to 6.5 mm. It is more preferably in the range of 0.5 mm to 4.5 mm. The size of the inner diameter r2 is 0 If set to 0.5 mm or more, the aerosol will flow through the through hole 31a of the support member 30. This makes it possible to secure the minimum required flow path size. Furthermore, the inner diameter r2 can be reduced to 6.5 mm or less. By setting it to this value, it is possible to secure the minimum thickness of the support member 30 necessary to support the object to be heated 20. This is possible. Also, if the inner diameter r2 is set to 4.5 mm or less, the heated object 20 will be supported. This makes it possible to ensure sufficient thickness for the support member 30.

[0028] When manufacturing the support member 30, the inner diameters r1 and r2 should be appropriately selected within the above range. Then, the size of the flow path in the support member 30 is adjusted to transfer the aerosol to the mouthpiece 40. A path can be secured. Also, the heating element 20 (aerosol-forming substrate 23) by the support member 30 The support strength can be adjusted to appropriately support the heated object 20 according to the material of the aerosol-forming substrate 23. Cut.

[0029] Furthermore, the length and inner diameters r1 and r2 along the central axis C1 of the support member 30 are aerosol forming Depending on the shape of the base material 23, the outer circumference of the support member 30 can be appropriately selected within the above range. By adjusting the tilt angle, the aerosol-forming substrate 23 is prevented from moving toward the mouthpiece 40. It can be stopped. For example, if the aerosol-forming substrate 23 is in the form of a powder, granules or capsules. In that case, the length of the support member 30 is set to be shorter, and the size of the inner diameter r1 is set to be larger than the size of the inner diameter r2. If set to be sufficiently larger than the width, the inclination of the outer circumference of the support member 30 with respect to the first end 30a will be The angle can be set to a small value. And at this time, the outer circumference of the support member 30 is the first end portion 30a It slopes downward from there toward the second end 30b. In this way, if the aerosol-forming substrate 23 Even if it enters the through hole 31a of the support member 30, the aerosol-forming substrate 23 will remain in the support member The outer circumference of 30 comes into contact with the mouthpiece 40, preventing it from moving toward the mouthpiece 40. Therefore, the support member 30 The movement of the aerosol-forming substrate 23 toward the mouthpiece 40 can be prevented within the through-hole 31a. Furthermore, the inner diameter r1 of the support member 30 is reduced, and the space between the inner diameter r1 and the outer diameter R1 of the support member 30 is reduced. If the thickness portion of the inner diameter r is sufficient to adequately support the aerosol-forming substrate 23, then the inner diameter r Regardless of 2, the aerosol-forming substrate 23 enters the through hole 31a of the support member 30. This will become difficult.

[0030] The outer diameter R1 of the support member 30 is preferably in the range of 4.0 mm to 7.5 mm. More preferably, it is in the range of 5.0 mm to 7.0 mm. Also, the outer diameter R of the support member 30. The size of 2 is preferably in the range of 1.0 mm to 7.5 mm, and more preferably 1. The range is 5mm to 6.5mm. The size of the outer diameter R1 is equal to the outer diameter D of the aerosol-forming substrate 23. It is preferable to set it to be equal to the size of the outer diameter R1 and the outer diameter It is preferable that the dimensions of D are the same. This way the aerosol-forming substrate 23 supports The first end 30a of the holding member 30 and the exterior member 10 move towards the support member 30. This can prevent it.

[0031] Next, referring to Figure 2, the outer diameter R1 and inner diameter r1 of the support member 30 and the aerosol forming group The relationship between the outer diameter D of material 23 and the following will be explained. The left side of Figure 2 shows the smoking device shown in Figure 1. A cross-section of Tridge 1 cut along line II-II, viewed from the support member 30 side. This is a longitudinal cross-section of the forming substrate 23, and the right-hand diagram of Figure 2 shows the same cross-section from the aerosol forming substrate 23 side. This is a longitudinal cross-section of the support member 30 as seen from the rear.

[0032] In Figure 2, L1 passes 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 circumference portion of the support member 30 (sheet-like member 31), and L3 is a support A straight line L4 passing through the bottom of the inner circumference of the support member 30 is the aerosol-forming substrate 23 and the support member. It is a straight line passing through the bottom of 30.

[0033] The outer diameter R1 of the support member 30 is set to be equal to the outer diameter D of the aerosol-forming substrate 23. As shown in 2, the outer diameter R1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 are both This corresponds to the length between L1 and L4. Therefore, the first end 30a of the support member 30 is E The outer peripheral portion of one end 23a of the allosol-forming substrate 23 can be supported. If the first end portion 30a of material 30 can support the outer periphery of the aerosol-forming substrate 23, then the outer diameter R 1 can be smaller than the outer diameter D.

[0034] Furthermore, the inner diameter r1 of the support member 30 corresponds to the length between L2 and L3, and aerosol formation It is smaller than the outer diameter D of the base material 23. Specifically, the inner diameter r1 of the support member 30 is smaller than the outer diameter D of the support member 30 The length (Δr) between L1 and L2 and between L3 and L4 from the outer diameter R1 (≤ outer diameter D) Length (Δr), that is, length excluding the thickness (2Δr) of the support member 30 (sheet-like member 31). This corresponds to the first end portion 30a of the support member 30, which is the thickness portion of the sheet-like member 31. This allows the aerosol-forming substrate 23 to be supported from its outer periphery to a predetermined inner range.

[0035] The magnitude of Δr described above is preferably in the range of 0.5 mm to 3.5 mm, and more preferably... The range is 1.0 mm to 3.25 mm. The size of Δr is set to 0.5 mm or larger. This makes it possible to secure the minimum thickness of the support member 30 necessary to support the object to be heated 20. Furthermore, if the size of Δr is set to 1.0 mm or more, in order to support the heated object 20 This makes it possible to ensure sufficient thickness for the support member 30. Furthermore, the size of Δr can be reduced to 3.5 mm or less. Once configured, the minimum necessary flow path is required for the aerosol to flow through the through-hole 31a of the support member 30. This makes it possible to secure the necessary size. Also, if the size of Δr is set to 3.25 mm or less, air This ensures that the flow path is large enough for the rosol to flow through the through hole 31a of the support member 30. ru.

[0036] Thus, the outer diameter R1 and inner diameter r1 of the support member 30 are equal to the outer diameter D of the aerosol-forming substrate 23. Because of the above-described relationship, the support member 30 is located on the outer circumference of the aerosol-forming substrate 23. It can support not only a portion of the area, but also the area from the outer periphery to the inside of a predetermined range.

[0037] Note that in Figure 1, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, The configuration is not limited to this. The thickness portion of the support member 30 (sheet-like member 31) is used to aerosol If one end 23a of the forming substrate 23 can be supported, the inner diameter r2 of the support member 30 is equal to the inner diameter r1 It may be equal to or greater than the inner diameter r1. The inner diameter r2 of the support member 30 is equal to the inner diameter r1 If this is the case, the inner diameter of the support member 30 is uniform from the first end 30a to the second end 30b. It should be formed in such a way. Also, if the inner diameter r2 of the support member 30 is larger than the inner diameter r1 Even if the inner diameter of the support member increases in the process from the first end 30a to the second end 30b That's fine, and it's also fine if it gradually increases from the first end 30a to the second end 30b. When the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and when it is greater than the inner diameter r1 In either case, the outer diameters R1 and R2 of the support member 30 may be made equal.

[0038] Furthermore, the support member 30 is configured such that various fillers are filled into its through hole 31a. It may be present. Such fillers include, for example, granular materials, fibrous materials, porous materials, and Flavoring additives are one example.

[0039] When granular material is used for filling, for example, plastic particles can be used. The shape of the granular material is particularly It is not limited to the above; for example, the cross-sectional shape may be round, elliptical, or polygonal. Also, granular material The particles can be solid or hollow, and their particle size is preferably, for example, 0.5 mm to 1 mm.

[0040] When fibrous materials are used as filling, for example, cellulose acetate (CA) fibers or polyethylene. Polyester fibers such as terephthalate (PET) can be used.

[0041] When a porous material is used as a filling, for example, polyolefin resins such as PE and PP, or PET resin. CA resin, polylactic acid (PLA), aluminum foil and other metals are used. can.

[0042] Furthermore, when the above-mentioned granular material is used as a filler, it is mixed into the aerosol. Activated carbon that can remove specific chemical substances (such as tar), as well as ceramics and glass, etc. Inorganic particles may be used as the material, and a mixture of multiple types of these particles may be used. It may be used. Also, the above chemical substances (e.g., formaldehyde) may be included in part or all of the filler. A removal agent (such as chitosan) that can remove aldehydes (such as hydrides) may be added.

[0043] Alternatively, if the granular material described above is used as the filling, coffee may be extracted from it. You can also use plant-based ingredients such as coffee grounds after brewing or tea leaves after extraction. These plant-based materials are porous and have a high deodorizing effect, so the support part has a deodorizing effect. Material 30 can be achieved. Furthermore, if coffee grounds are used, the coffee grounds will remain as they are. Because of its small particle size, it is preferable to use it in the form of small balls made with starch or other ingredients. If shells are used, the aerosol-forming substrate 23 will be made of tea leaves. Both 23 and the support member 30 can be manufactured from the same material.

[0044] If flavorings are added, for example, mint, cocoa, coffee, tea extract, etc. The resulting catechin powder can be used. The flavor additive is filled into the through-hole 31a of the support member 30. Various methods of filling can be described below.

[0045] For example, if a flavor additive is enclosed in a capsule, this capsule is placed inside the through-hole 31a. It can be placed in this way. This way, the smoker can destroy the capsule by pressing it with their finger. This allows the aromatic components of the flavor additive to volatilize at the desired timing. If it is molten, the capsule will melt when exposed to an aerosol, and the flavor will be enhanced. The additive can be released to the outside. Furthermore, if this capsule is a microcapsule, this The microcapsule may be embedded in the inner circumferential surface of the support member 30. Of course, the microcapsule may be It may also be placed inside the through-hole 31a. Note that if the flavor additive is not enclosed in the capsule, For example, a flavoring additive may be impregnated into the inner surface of the support member 30.

[0046] Next, specific examples of raw materials used as aerosol-forming substrates 23 will be described. The rosol-forming substrate 23 is composed of any one or more combinations of the raw materials shown below. It will be done.

[0047] The aerosol-forming substrate 23 is made from tobacco plants or non-tobacco plants. Examples include tobacco leaves, tobacco stems, expanded tobacco, and homogenized tobacco. Non-tobacco plants Examples of desirable materials include plants other than tobacco plants. Desirable parts of non-tobacco plants include: , leaves, pulp, seeds, roots (scaly roots, tuberous roots, etc.), stems, tubers, skin (stem bark, bark, etc.), flowers (petals, male Examples include the stamens, pistils, trunk, and branches.

[0048] In this specification, "plants" refers to a group of things as opposed to animals, such as grass and trees. Besides organisms that have roots and are fixed in place, there are also microalgae and seaweed, etc. This includes algae, fungi such as mushrooms, and other similar organisms.

[0049] The aerosol-forming substrate 23 generates aerosols, for example, on dried and crushed non-tobacco plants. Aerosol former to be generated, microcrystalline cellulose, flavoring additives, preservatives, Adhesives or thickeners are mixed as appropriate, and then crushed or classified to form powder or granules, or paper It is formed into a strip shape. In addition, the aerosol-forming substrate 23 is formed into a sheet shape and then a predetermined They are cut to have a certain width and length, resulting in strips or rods.

[0050] For example, if the part of a non-tobacco plant is the leaves, tea can preferably be used. It's not just that different plants are used to make tea; even with the same plant, different processing methods result in different types of tea. Specifically, for example, Japanese tea, black tea, Angelica keiskei tea, hydrangea tea, Gynostemma pentaphyllum tea, aloe vera tea, Ginkgo leaf tea, oolong tea, turmeric tea, evergreen oak tea, Eleutherococcus senticosus tea, plantain tea, Kiodoshi tea, persimmon leaf tea, chamomile tea, cassia seed tea, quince tea, chrysanthemum tea, Gymnema tea, guava tea, goji berry tea, yalanthus leaf tea, black bean tea, geranium tea, brown rice tea, burdock Tea, comfrey tea, hibi tea, cherry blossom tea, saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, shi Ginger tea, horsetail tea, sweet flag tea, swertia tea, buckwheat tea, angelica tree tea, dandelion tea, sweet Tea, Houttuynia cordata tea, Eucommia ulmoides tea, Sword bean tea, Elderberry tea, Privet tea, Job's tears tea, Senna tea Loquat leaf tea, Pu-erh tea, safflower tea, pine needle tea, mate tea, barley tea, Japanese star anise tea, mugwort tea Examples include eucalyptus tea, monk fruit tea, rooibos tea, and bitter melon tea. You can also use the tea leaves after drinking. Using tea leaves allows you to reuse expensive tea. It can be put to good use.

[0051] Furthermore, extracts of non-tobacco plants, so-called extracts and processed products, as exemplified above, can also be used. Yes, it is possible. The extract can take the form of liquid, syrup, powder, granules, solution, etc.

[0052] The aerosol former used as a raw material for the aerosol-forming substrate 23 is glycerin, propylene Glycerin glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin Diacetate, triacetin (glycerin triacetate), triethylene glycol Diacetate, triethyl citrate, isopropyl myristate, methyl stearate, Examples include dimethyl dodecanedione and dimethyl tetradecanedione. However, glycerin and propylene glycol are preferred.

[0053] Microcrystalline cellulose as a raw material for the aerosol-forming substrate 23 is, for example, from fibrous plants. It is obtained by partially depolymerizing α-cellulose obtained from pulp with acid. It is made by removing the soluble portion from cellulose and crystallizing the insoluble portion as appropriate. .

[0054] Microcrystalline cellulose can be used as a powder or dispersed in a solvent such as water to form a suspension solution. In this case, a high-speed stirrer or a high-pressure homogenizer can be used to disperse the mixture into the solvent.

[0055] Furthermore, if necessary, flavor additives can be used as raw materials for the aerosol-forming substrate 23 to add flavor. It is preferably used. Flavoring additives include mint, cocoa, coffee, and tea extracts. Examples include catechin powder from tea extract. Food preservatives are preferred. Examples include sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate. It can be done.

[0056] The aerosol-forming substrate 23 contains menthol and a water-insoluble crosslinked polymer (preferably poly It may also contain vinylpolypyrrolidone. A non-water-soluble crosslinked polymer is combined with menthol. By combining them, the sublimation of menthol can be effectively suppressed, preserving the menthol flavor for a longer period. This is possible. Here, menthol is not limited to that obtained from natural products, but also includes synthetic products. That's also good. You can also use peppermint, mint, peppermint oil, or other menthol-containing products. good.

[0057] Flavoring additives can be used, for example, by impregnating the walls of the mouthpiece 40. It is provided in part 40. The embodiment in which the flavor additive is provided in the mouthpiece 40 is this The following is not limited to such embodiments; for example, the capsule containing the flavor additive can be used as a mouthpiece. The mouthpiece 40 is provided with a flavor additive by embedding it in the wall of the mouthpiece 40. Alternatively, a flavor additive may be sealed between the mouthpiece 40 and the heated object 20. The capsules may be arranged in such a way that flavoring additives are sealed inside the capsules. In this case, the smoker can break the capsule by pressing it with their finger. This makes it possible to volatilize the aromatic components of flavor additives at the desired timing.

[0058] Furthermore, if the flavor additives are encapsulated in microcapsules, for example, they are enclosed in microcapsules. The microcapsules may be placed on the heated object 20. Of course, the microcapsules may be supported It may also be provided on the support member 30.

[0059] The binder or thickener used as a raw material for the aerosol-forming substrate 23 is guar gum, ki Gums such as santhan gum, acacia gum, and locust bean gum, for example, hydroxy Propylcellulose, carboxymethylcellulose, hydroxyethylcellulose, Cellulose binders such as cellulose and ethylcellulose, for example, starch, aluminum Organic acids such as ginic acid, sodium alginate, sodium carboxymethylcellulose, Polysaccharides such as caranagin, agar, and conjugated base salts of organic acids such as pectin, and these One possible combination is...

[0060] (Method for manufacturing aerosol-forming substrate) The method for manufacturing the aerosol-forming substrate 23 described above will be explained step by step. The manufacturing process for the sol-forming substrate 23 involves drying and powdering the main raw material, either tobacco or non-tobacco plant. The process includes a drying and grinding step where materials are crushed and weighed, and a preparation step where other raw materials are pre-treated and weighed. The process comprises a mixing step of mixing raw materials to form a composition, and a filling molding step of molding the composition. ru.

[0061] In the drying and grinding process, the main raw material is the tobacco plant or the part of the non-tobacco plant used (for example) The composition is made from (leaves, seeds, dried fruits, stems, bark, roots, etc.) and is processed into a predetermined pulverized material. At that time, the aerosol former, water, and other components to be added later are absorbed or supported. It is preferable to adjust the moisture content to a level that is convenient for this purpose. During drying, the temperature should be 60°C or higher and 80°C or higher. A temperature of ℃ or lower is preferable. By keeping it within this range, the desired flavor components are avoided from dissipating. It is easy to reach the desired moisture content. Furthermore, the drying and grinding process includes a sieving process to separate the ground material. A filter can also be provided, allowing the material to be adjusted to the desired particle size before being introduced into the mixing process.

[0062] In the preparation process, the raw materials necessary for producing the aerosol-forming substrate 23 are prepared. This can be done. The aforementioned microcrystalline cellulose is weighed in the preparation step and added to the mixing step. To be admitted.

[0063] In the mixing process, a standard mixer can be used. For example, raw materials in a mixing tank A preferred method involves mixing the mixture using stirring blades while applying shear force.

[0064] In the filling molding process, the composition, which is a mixture of various raw materials, is formed into a thin sheet, and then cut. By cutting, a strip-shaped or rod-shaped aerosol-forming substrate 23 is formed. To make a thin sheet, multiple roll mills are prepared. Then, due to compression caused by being pressed between the narrow rolls and shear caused by the difference in roll speed, By kneading, dispersing, etc., the material can be formed into a sheet of the desired thickness using a doctor blade. It is possible and preferable. It can also be manufactured using a press roller or press machine. Cut.

[0065] Furthermore, in order to obtain a powder or granular aerosol-forming substrate 23, the above composition may be appropriately... It is preferable to perform grinding or classification. The average particle size is preferably, for example, 0.1 to 3.0 mm, and 0.5 mm or less. It is more preferable that this be the case. The average particle size is, for example, as defined in JIS K 0069:1992. It is determined by the sieving method described. In other words, this average particle size is determined by multiple sieves. Regarding the test results, the mass was calculated by summing the mass from the side with the larger opening, and this corresponds to 50% of that mass. This refers to the diameter. Also, the integrated value of the particle size distribution obtained by laser diffraction and scattering method 50 The particle size in percent may be used as the average particle diameter.

[0066] In the filling molding process, the composition is molded by passing it through an orifice under pressure, and other processes are also involved. The means may be used. In addition, in the filling molding process, non-tobacco plants and aero may be used as needed. You may also add solformer, binders or thickeners, flavorings, and preservatives. You may add water or other liquids.

[0067] The thickness of the sheet obtained in the filling molding process is preferably in the range of 0.1 mm to 1.0 mm. More preferably, the thickness is in the range of 0.1 mm to 0.5 mm. The resulting sheet is cut with a cutter. The material is then cut to a predetermined width using a rotary cutter or the like.

[0068] Here, if tackiness is to be imparted to the surface of the aerosol-forming substrate 23, tackiness can be imparted. The method is not particularly limited, but it is sufficient to apply the aforementioned binder to at least a portion of it. By imparting tackiness, the strip-shaped or rod-shaped aerosol-forming substrate 23 and the powder-like or granular material can be combined. Alternatively, when combined with a paste-like aerosol-forming substrate 23, strip-shaped or rod-shaped A powder, granular, or paste-like aerosol-forming substrate 23 is applied to the surface of the aerosol-forming substrate 23. It can be held stably.

[0069] (How to use smoking accessory cartridges) This section explains how to use the smoking accessory cartridge 1. Figure 3 shows the smoking accessory cartridge 1. This is a cross-sectional view of the cartridge inserted into the smoking device 70. The smoking device cartridge 1 is a heated smoking device It is used when attached to the smoking device 70. The smoking device 70 is used to insert the smoking device cartridge 1. It has an insertion portion 72. The insertion portion 72 is provided with a needle-shaped or blade-shaped heating portion 75. It can be inserted. When the smoking device cartridge 1 is inserted into the insertion part 72, the heating part 75 generates heat. As a result, an aerosol is generated from the aerosol-forming substrate 23. In this state, the smoker When the user puts the mouthpiece 40 in their mouth and inhales, the aerosol enters the through hole 31a of the support member 30. The liquid flows through the mouthpieces in order, into the smoker's mouth.

[0070] According to the smoking device cartridge 1 configured in this manner according to the first embodiment, the following effects are achieved. It can be effective.

[0071] Since the inner diameter r1 of the support member 30 is smaller than the outer diameter D of the aerosol-forming substrate 23, support The thickness portion between the inner diameter r1 and outer diameter R1 of member 30 causes the heated object 20 (aerosol type) to be heated. The base material 23) can be supported. Therefore, the heating element 20 (aerosol-forming base material 23) can be supported. Movement toward the holding member 30 can be suppressed.

[0072] Furthermore, the dimensions of the outer diameter R1 of the support member 30 and the heated object 20 (aerosol-forming substrate 23) The outer diameter D dimension and the first can be set to be the same, and if the two are the same, the first of the support member 30 The entire end portion 30a can come into contact with the aerosol-forming substrate 23. Therefore, the support member 30 Therefore, the heated object 20 (aerosol-forming substrate 23) can be sufficiently supported. The movement of 23) toward the support member 30 can be further suppressed. Also, the aerosol-forming substrate 23 , moving towards the support member 30 side, passing between the first end 30a of the support member 30 and the exterior member 10. This can prevent that from happening.

[0073] Furthermore, the shape of the first end 30a of the support member 30 is different from the shape of the second end 30b, The shape of the through-hole 31a of the support member 30 is not uniform along the central axis C1. Therefore, if Even if a portion of the aerosol-forming substrate 23 enters the through-hole 31a, it will not move inside it. That is difficult.

[0074] Furthermore, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, and the through hole 3 of the support member 30 The diameter of 1a is smaller at the second end 30b than at the first end 30a. Therefore, the through hole 31 This makes it even more difficult for the aerosol-forming substrate 23 that has entered the interior of a to move.

[0075] Furthermore, the support member 30 gradually moves inward from the first end 30a towards the second end 30b. Because it is formed to have a small diameter, the aerozoites that enter the through hole 31a of the support member 30 The aerosol-forming substrate 23 and the inner circumference of the through hole 31a collide. Moreover, this colliding aerosol The space for the air-forming substrate 23 to escape is restricted. Therefore, air that enters the through hole 31a This prevents the movement of the rosol-forming substrate 23.

[0076] Furthermore, since the support member 30 is formed by winding a sheet-like member 31, the aerosol-forming substrate Friction is likely to occur between 23 and the sheet-like member 31. Therefore, the through hole 31 of the support member 30 This further prevents the movement of the aerosol-forming substrate 23 that has entered into a.

[0077] Furthermore, since the support member 30 has a simple structure in which a sheet-like member 31 is wound into a cylindrical shape, Manufacturing costs can be reduced.

[0078] (Second Embodiment) Next, a cartridge for a smoking device according to the second embodiment will be described. The smoking device cartridge 2 is basically the same as the smoking device cartridge 1 according to the first embodiment. Although the configuration is the same, the difference is that the support member 30 is made of a frustoconical resin molded product 32. Therefore, the following explanation will focus on these differences, and will omit explanations that overlap with the first embodiment. do.

[0079] Figure 4 is a cross-sectional view of the smoking device cartridge 2 according to the second embodiment. As shown in Figure 4 The support member 30 (resin molded product 32) has its lower bottom surface facing the aerosol forming substrate 23. The upper bottom surface is positioned opposite the mouthpiece 40. The first end of the support member 30 The shape of part 30a differs from the shape of the second end portion 30b. The support member 30 has a frustoconical shape inside. It has a through hole 32a, and the inner diameter r1 of the support member 30 is larger than the inner diameter r2. The outer diameter R1 of the first end 30a of the support member 30 is larger than the outer diameter R2 of the second end 30b. Furthermore, multiple recesses 32c are formed on the outer circumferential surface 32b of the support member 30. Instead of the recess 32c, multiple protrusions may be formed.

[0080] Next, referring to Figure 5, the outer diameter R1 and inner diameter r1 of the support member 30 and the aerosol forming group The relationship between the outer diameter D of material 23 and the following will be explained. The left side of Figure 5 shows the smoking device shown in Figure 4. Aerosol formation observed from the support member 30 side of the cross-section obtained by cutting the cartridge 2 along the VV line. This is a longitudinal cross-section of the substrate 23, and the right-hand diagram in Figure 5 shows the same cross-section viewed from the aerosol-forming substrate 23 side. This is a vertical cross-section of the support member 30.

[0081] As shown in Figure 5, the outer diameter R1 of the support member 30 (resin molded product 32) and aerosol formation The outer diameter D of the base material 23 corresponds to the length between L1 and L4. Also, the support member 30 The inner diameter r1 is the length between L2 and L3, that is, from the outer diameter R1 (= outer diameter D) of the support member 30. This corresponds to the length of the support member 30 excluding the thickness (2Δr) of the thickened portion.

[0082] According to the second embodiment of the smoking device cartridge 2 configured in this way, The same effects as in the first embodiment can be achieved. Furthermore, according to the second embodiment, support Since the outer diameter R1 of member 30 is larger than the outer diameter R2, the support member 30 has a large aerodynamic area. It can contact one end 23a of the sol-forming substrate 23. In particular, the support member 30 is a frustoconical tree Since it is made of a resin molded product 32, one end of the aerosol-forming substrate 23 is formed by its thickness 23a can be reliably supported, and the heated object 20 (aerosol-forming substrate 23) is on the support member 30 side. It can reliably suppress their movement.

[0083] Furthermore, since multiple recesses 32c are formed on the outer peripheral surface 32b of the support member 30, smoking device During the manufacturing of the cartridge 2, the support member 30 becomes easier to grip, thus improving manufacturing efficiency. Of course, instead of multiple recesses 32c, multiple protrusions may be formed, and in that case as well. It produces the following effects.

[0084] Note that in Figure 4, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, The configuration is not limited to this. The thickness of the support member 30 (resin molded product 32) determines the aerosol shape. If one end 23a of the base material 23 can be supported, the inner diameter r2 of the support member 30 is equal to the inner diameter r1. It may be equal to or greater than the inner diameter r1. The inner diameter r2 of the support member 30 is equal to the inner diameter r1. If equal, the inner diameter of the support member 30 is uniform from the first end 30a to the second end 30b. It should be formed in such a way. Also, if the inner diameter r2 of the support member 30 is larger than the inner diameter r1, The inner diameter of the support member 30 increases as it moves from the first end 30a to the second end 30b. It is also fine if it gradually increases from the first end 30a to the second end 30b. In addition, when the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and when it is greater than the inner diameter r1 In either case, the outer diameters R1 and R2 of the support member 30 may be made equal.

[0085] (Third embodiment) Next, a cartridge for a smoking device according to the third embodiment will be described. The cartridge 3 for the smoking device consists of a support made of a cylindrical body formed by winding a sheet-like member 33. The member 30 has multiple (four in this embodiment) protrusions 33b on its inner circumferential surface 33a. This differs from the first embodiment.

[0086] The four protruding portions 33b are each part (4 locations) of the outer circumferential surface 33c of the sheet-like member 33. A diagonal cut is made along the longitudinal direction, and the portion with this cut is folded inward. It is formed by extending the four protrusions 33b along the central axis C1 and the support member 30 They are arranged at equal intervals (90-degree intervals) in the circumferential direction (see Figure 7 below). Each protruding portion 33b is The width W1 of the support member 30 on the first end 30a side will be narrower than the width W2 of the second end 30b side. It is formed in a manner. Furthermore, the width of each protruding portion 33b is from the first end 30a of the support member 30 to the second It gradually widens towards the end 30b. Note that the first end 30 of the support member 30 The shape of a is different from the shape of the second end portion 30b.

[0087] The width W1 of the support member 30 is preferably in the range of 0.5 mm to 4.0 mm. More preferably, the width W1 is in the range of 1.0 mm to 3.0 mm. Setting it upwards ensures that the minimum width of the support member 30 necessary to support the heated object 20 can be secured. It becomes possible. Also, if the width W1 is set to 1.0 mm or more, it will support the heated object 20. This makes it possible to secure a sufficient width for the support member 30. Furthermore, the width W1 is 4.0m If set to m or less, the aerosol will flow within the region of circle C shown by the dotted line in Figure 7, which is the minimum required. This makes it possible to secure the necessary flow path size. Also, the width W1 can be set to 3.0 mm or less. Therefore, the flow path size is sufficient for the aerosol to flow through the region within circle C, indicated by the dotted line in Figure 7. This makes it possible to secure [something].

[0088] Furthermore, the width W2 of the support member 30 is preferably in the range of 0.5 mm to 4.0 mm. More preferably, it is in the range of 1.25 mm to 3.25 mm. The size of the width W2 is 0 If set to 0.5 mm or more, the minimum support member 30 required to support the heated object 20 will be This allows for sufficient width. Also, if the width W2 is set to 1.25 mm or more, the heated body This makes it possible to secure a sufficient width for the support member 30 to support 20. Furthermore, the size of the width W2 If the gap is set to 4.0 mm or less, the aerosol will flow within the area of ​​circle C' indicated by the dotted line in Figure 7. This makes it possible to secure the minimum necessary flow path size for this purpose. Also, the width W2 is 3.2 If set to 5 mm or less, the aerosol will flow within the region of circle C' shown by the dotted line in Figure 7. This makes it possible to secure a sufficient channel size.

[0089] When manufacturing the support member 30, the widths W1 and W2 can be appropriately selected within the above range. The size of the flow path of the support member 30 can be adjusted. Also, the heat source 20 of the support member 30 The support strength of the aerosol-forming substrate 23) is adjusted according to the material of the aerosol-forming substrate 23. The heated object 20 can be properly supported.

[0090] In the following explanation, for the sake of convenience, of the four protruding parts 33b, the support member 30 (sheet-like part) will be referred to as the support member 30 (sheet-like part). The protruding portion 33b formed at the top of material 33) is called the "first protruding portion 331b", and this first protruding portion The protruding ridges 33b are formed at positions rotated 90 degrees clockwise from the ridge 331b. These are then sequentially referred to as "second protrusion 332b", "third protrusion 333b", and "fourth protrusion 334 "b"

[0091] Next, referring to Figure 7, the outer diameter R and inner diameter r1 of the support member 30 and the aerosol-forming substrate. The relationship between the outer diameter D of 23 and the following will be explained. The left side of Figure 7 shows the smoking accessory car shown in Figure 6. A cross-section of ridge 3 cut along line VII-VII, viewed from the support member 30 side. This is a longitudinal cross-section of the aerosol-forming substrate 23, and the right-hand diagram of Figure 7 shows the same cross-section from the aerosol-forming substrate 23 side. This is a vertical cross-section of the support member 30 as viewed from the front. In Figure 7, L2 is the third of the support member 30. L3 is a straight line passing through the tip of the first projection 331b at end 30a, and L3 is the third projection It is a straight line passing through the tip of part 33b. Also, in the right-hand diagram of Figure 7, the circle C shown by the dotted line is the It is drawn by connecting the tips of the 1st to 4th protrusions 331b to 334b ​​in an arc, and its diameter is supported This represents the inner diameter r1 of member 30.

[0092] As shown in Figure 7, the outer diameter R of the support member 30 (sheet-like member 33) and aerosol formation The outer diameter D of the base material 23 corresponds to the length between L1 and L4. Also, the support member 30 The inner diameter r1 is the length between L2 and L3, which corresponds to the diameter of circle C, i.e., the outer diameter of the support member 30. From R (=outer diameter D), the width (W1) of the first protrusion 331b and the width (W) of the third protrusion 333b This corresponds to the value excluding 1). Note that in the right-hand diagram of Figure 7, each protruding part 33b is a circle The portion protruding inward from C is directed from the first end 30a to the second end 30b of the support member 30. This is the part that was once wider.

[0093] According to the third embodiment of the smoking device cartridge 3 configured in this way, The same effects as in the first embodiment can be achieved. Furthermore, according to the third embodiment, support Member 30 has a plurality of protrusions 33b extending along the central axis C1 on its inner circumferential surface 33a. Therefore, the aerosol-forming substrate 23 can be firmly supported at the first end 30a side of the support member 30. Furthermore, since the multiple protrusions 33b are arranged at equal intervals of four in the circumferential direction of the support member 30, The aerosol-forming substrate 23 can be supported in a well-balanced manner.

[0094] Furthermore, the support member 30 is formed by winding a sheet-like member 33, and has multiple protruding portions 33b Each of these is formed by folding a portion of the outer surface 33c of the sheet-like member 33 inward. Therefore, the support member 30 can have a simple structure, and manufacturing costs can be reduced.

[0095] Furthermore, the support member 30 may be made of a resin molded product, as in the second embodiment. In this case, the multiple protruding portions are formed by resin molding so as to protrude from the inner circumferential surface of the support member 30. It would be fine if there were more than four protrusions 33b. That would be good.

[0096] In Figure 6, the width W1 of the support member 30 is formed to be narrower than the width W2. However, the configuration is not limited to this. Multiple protrusions 33b of the support member 30 create an aerosol shape If one end 23a of the base material 23 can be supported, the width W2 of the support member 30 will be equal to the width W1. It may be wider than or equal to width W1. If the width W2 of the support member 30 is equal to width W1, The width of the support member 30 from the first end 30a to the second end 30b is It is sufficient to form it so that it is uniform toward the end 30b. Also, the width W2 of the support member 30 is If the width is greater than W1, the width of the support member 30 from the first end 30a to the second end 30b is It may also increase in size on the way from the first end 30a to the second end 30b, and the first end 3 It is acceptable for the value to gradually increase from 0a towards the second end 30b.

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

[0098] The blocking portion 34 protrudes from the inner circumferential surface toward the central axis C1 at the first end portion 30a of the support member 30. It consists of multiple (six in this embodiment) protrusions 34a. The support member 30 is located on the central axis C1. It has a cylindrical portion 35 arranged along it, and six protrusions 34a form aerosols in the cylindrical portion 35. These protrusions 34a are provided on the substrate 23 side. The support members 3 are arranged at equal intervals (60-degree intervals) in the circumferential direction, facing 23a. The shape of the first end 30a of 0 is different from the shape of the second end 30b.

[0099] In the following explanation, for the sake of convenience, of the six protruding parts 34a, the support member 30 (cylindrical part 35 The protrusion 34a formed at the top of ) is called the "first protrusion 341a", and this first protrusion 3 The protrusions 34a, formed at positions rotated 60 degrees clockwise from 41a, are sequentially , "second protrusion 342a", "third protrusion 343a", "fourth protrusion 344a", "fifth protrusion These are referred to as "protrusion 345a" and "sixth protrusion 346a".

[0100] Next, referring to Figure 9, the outer diameter R and inner diameter r1 of the support member 30 and the aerosol forming substrate. The relationship between the outer diameter D of 23 and the following will be explained. The left side of Figure 9 shows the smoking accessory car shown in Figure 8. The cross-section of Tridge 4 cut along the IX-IX line, viewed from the support member 30 side, is an aerosol shape. This is a longitudinal cross-section of the substrate 23, and the right-hand diagram in Figure 9 shows the same cross-section from the aerosol-forming substrate 23 side. This is a vertical cross-section of the support member 30. In Figure 9, L2 is the first projection of the support member 30. L3 is a straight line passing through the tip of the protrusion 341a, and L3 is the fourth protrusion 344a of the support member 30. It is a straight line passing through the tip. Also, in the diagram on the right in Figure 9, the dotted circle C' represents the 1st to 6th The tip of the protruding parts 341a to 346a is connected in an arc, and its diameter is the same as that of the support member 30 This represents the inner diameter r1. The size of this inner diameter r1 is, for example, 6.5 mm or less.

[0101] As shown in Figure 9, the outer diameter R of the support member 30 and the outer diameter D of the aerosol forming substrate 23 are Also, it corresponds to the length between L1 and L4. Furthermore, the inner diameter r1 of the support member 30 is the length of circle C'. The length between L2 and L3, which corresponds to the diameter, that is, from the outer diameter R (= outer diameter D) of the support member 30. The amount of protrusion (T) of the first protrusion 341a and the amount of protrusion (T) of the fourth protrusion 344a correspond to the above. This corresponds to the value excluding the length. Note that the magnitude of the protrusion (T) is, for example, 0.5 mm to 3.5 mm. A range of mm is preferred, and more preferably a range of 1.0 mm to 3.25 mm. If the size of the quantity (T) is set to 0.5 mm or more, then the minimum amount of material required to support the heated object 20 is This makes it possible to secure the required amount of protrusion of the support member 30. Also, the size of the protrusion amount (T) can be set to 1.0 m Setting it to m or more ensures sufficient protrusion of the support member 30 to support the object to be heated 20. This becomes possible. Furthermore, if the protrusion amount (T) is set to 3.5 mm or less, the aerosol This ensures that the minimum required channel size is secured for the flow to occur within the region of circle C' indicated by the dotted line in Figure 9. It becomes possible. Also, if the protrusion amount (T) is set to 3.25 mm or less, the aerosol In Figure 9, it is possible to ensure a sufficient channel size for flow within the region of circle C' indicated by the dotted line. .

[0102] When manufacturing the support member 30, the size of the protrusion amount (T) can be appropriately selected within the above range. The size of the flow path on the first end 30a side of the support member 30 can be adjusted. The support strength of the heated object 20 (aerosol-forming substrate 23) is adjusted by the aerosol-forming substrate The heated object 20 can be appropriately supported depending on the material of 23.

[0103] According to the smoking device cartridge 4 configured in this way according to the fourth embodiment, The same effects as in the first embodiment can be achieved. Furthermore, according to the fourth embodiment, support The first end portion 30a of member 30 is used to move the heated object 20 (aerosol-forming substrate 23) in the axial direction. Because a blocking portion 34 is formed to prevent movement, the heated object 20 (aerosol-forming substrate 23) The movement of the support member 30 towards the support member 30 can be reliably suppressed. Moreover, the six protrusions serve as the blocking portion 34. Since part 34a is provided along the circumferential direction of the support member 30, the outside of the aerosol-forming substrate 23 The circumferential portion and the portion inside a predetermined range from the outer periphery can be reliably supported.

[0104] Furthermore, since the six protrusions 34a are arranged at equal intervals in the circumferential direction, a well-balanced aerozo It can support the lubricating substrate 23.

[0105] Furthermore, a blocking portion 34 (multiple protrusions 34a) is formed only at the first end portion 30a of the support member 30. Therefore, the support member 30 can be made with a simple structure, and manufacturing costs can be reduced. .

[0106] Note that in Figure 8, the blocking portion 34 is formed only on the first end 30a side of the support member 30. However, it may also be formed on the second end 30b side. In this case, the blocking portion on the second end 30b side The amount of protrusion is equal to the amount of protrusion (T) of the blocking portion 34 on the first end 30a side, or this amount of protrusion (T) may be formed differently, in which case the blocking portion 34 on the first end 30a side and the It may be formed so as to connect with the blocking portion on the second end 30b side. Blocking portion on the second end 30b side If the amount of protrusion is equal to the amount of protrusion (T) of the blocking portion 34 on the first end 30a side, then the first end 30a The amount of protrusion of the blocking portion from the side to the second end 30b is from the first end 30a to the second end 30b. It should be formed so that it is uniform toward the end. Also, the amount of protrusion of the blocking portion on the second end 30b side If the amount of protrusion (T) of the blocking portion 34 on the first end 30a side is different, the second The amount of protrusion of the blocking portion leading to end 30b is determined by the time it is moving from the first end 30a to the second end 30b. The size can change, and it can gradually increase from the first end 30a to the second end 30b. It's okay if it gets louder.

[0107] (Fifth embodiment) Next, a cartridge for a smoking device according to the fifth embodiment will be described. The fourth embodiment of the smoking device cartridge 5 is that it has a mesh-like member 34b as a blocking part 34. It differs in form.

[0108] The mesh-like member 34b covers the first end portion 30a of the support member 30 (cylindrical portion 35), and The shape of the first end 30a of the holding member 30 is different from the shape of the second end 30b. Mesh-like part Material 34b consists of, for example, a wire mesh member, and the size of its mesh is such that the aerosol-forming substrate 2 The size is set so that 3 cannot pass through. The material of the mesh-like member 34b is relatively heat-resistant. Any high-quality material will suffice. Alternatively, perforated plates can be used as a substitute. can.

[0109] Next, referring to Figure 11, the outer diameter R and inner diameter r1 of the support member 30 and the aerosol forming group The relationship between the outer diameter D of material 23 and the following will be explained. The left side of Figure 11 shows the smoking device shown in Figure 10. A cross-section of the cartridge 5 cut along the XI-XI line, viewed from the support member 30 side. This is a longitudinal section of the sol-forming substrate 23, and the right-hand figure in Figure 11 shows the same cross-section of the aerosol-forming substrate 2 This is a vertical cross-section of the support member 30 as viewed from side 3.

[0110] As shown in Figure 11, the outer diameter R of the support member 30 and the outer diameter D of the aerosol forming substrate 23 are Both correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 is L2 and This corresponds to the length between L1 and L2, and is the distance between the outer diameter R (=outer diameter D) of the support member 30 and L1 and L2. Length (Δr) and length between L4 and L5 (Δr), that is, the thickness of the cylindrical part 35 (2Δr This corresponds to the length excluding ().

[0111] According to the smoking device cartridge 5 configured in this manner according to the fifth embodiment, The same effects as in the first embodiment can be achieved. Furthermore, according to the fifth embodiment, The mesh-like member 34b, which is part 34, is provided so as to cover the first end 30a of the support member. Therefore, it can support the entire surface of the aerosol-forming substrate 23 and reliably prevent the heated body 20 (aerosol-forming substrate 23) from moving toward the support member 30 side.

[0112] Also, 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 be made to 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 first end portion 30a side of the support member 30, but it may also be formed on the second end portion 30b side. In this case, the diameter of the mesh-like member on the second end portion 30b side (the inner diameter r2 of the support member 30) is equal to the diameter of the mesh-like member 34b on the first end portion 30a side (the inner diameter r1 of the support member 30), or it may also be larger than the diameter of this mesh-like member 34b. Also, when the diameter of the mesh-like member on the second end portion 30b side is equal to the diameter of the mesh-like member 34b on the first end portion 30a side, 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 second end portion 30b side is larger than the diameter of the mesh-like member 34b on the first end portion 30a side, 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 it 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 adopted.

[0114] (Sixth Embodiment) Next, the cartridge for a smoking implement according to the sixth embodiment will be described. The cartridge 6 for a smoking implement according to the sixth embodiment

[0115] is different from the fourth embodiment in that the blocking portion 36 has a saw blade shape. ]

[0115] The blocking portion 36 protrudes from the inner circumferential surface toward the central axis C1 at the first end portion 30a of the support member 30. It consists of multiple (eight in this embodiment) protrusions 36a. The tip of each protrusion 36a is pointed. Therefore, the multiple protrusions 36a are on the aerosol-forming substrate 23 side of the cylindrical portion 35 of the support member 30. They are arranged at equal intervals (45-degree intervals) in the circumferential direction. As a result, the blocking portion 36 has a sawtooth shape. The shape of the first end portion 30a of the support member 30 is the same as the shape of the second end portion. Its shape is different from that of 30b.

[0116] In the following explanation, for the sake of convenience, of the eight protrusions 36a, the support member 30 (cylindrical portion 35 The protrusion 36a formed at the top of ) is called the "first protrusion 361a", and this first protrusion 3 The protrusions 36a, formed at positions rotated 45 degrees clockwise from 61a, are sequentially , "second protrusion 362a", "third protrusion 363a", "fourth protrusion 364a", "fifth protrusion "Protrusion 365a", "Sixth Protrusion 366a", "Seventh Protrusion 367a", and "Eighth Protrusion" It says "Exit 368a".

[0117] Next, referring to Figure 13, the outer diameter R and inner diameter r1 of the support member 30 and the aerosol forming group The relationship between the outer diameter D of material 23 and the following will be explained. The left side of Figure 13 shows the smoking device shown in Figure 12. A cross-section of the cartridge 6 cut along line XIII-XIII, viewed from the support member 30 side. This is a longitudinal cross-section of the aerosol-forming substrate 23, and the right-hand figure of Figure 13 shows the same cross-section in an aerosol shape. This is a vertical cross-section of the support member 30 as viewed from the base material 23 side. In Figure 13, L2 is the support L3 is a straight line passing through the tip of the first projection 361a of the support member 30, and L3 is the first projection of the support member 30 5. This is a straight line passing through the tip of the protruding portion 365a. Also, in the right-hand diagram of Figure 13, it is shown as a dotted line. Circle C' is drawn by connecting the tips of the first to eighth projections 361a to 368a in an arc, The diameter of the support member 30 represents the inner diameter r1.

[0118] As shown in Figure 13, the outer diameter R of the support member 30 and the outer diameter D of the aerosol forming substrate 23 are Both correspond to the length between L1 and L4. Also, the inner diameter r1 of the support member 30 is circle C'. The length between L2 and L3, which corresponds to the diameter, that is, the outer diameter R (= outer diameter D) of the support member 30. The protrusion amount (T) of the first protrusion 361a and the protrusion amount (T) of the fifth protrusion 365a correspond to these values. This corresponds to the value excluding the length.

[0119] According to the smoking device cartridge 6 configured in this manner according to the sixth embodiment, The same effects as those of the first and fourth embodiments can be achieved. Furthermore, the sixth embodiment Depending on the configuration, the multiple protrusions 36a of the blocking portion 36 have a sawtooth shape, so if aerozo Even if a portion of the aerosol-forming substrate 23 enters the interior of the support member 30, the aerosol-forming substrate 23 Because it gets caught on the pointed tips of the multiple protrusions 36a, it becomes difficult to move. Therefore, the object being heated The movement of the body 20 (aerosol-forming substrate 23) toward the support member 30 can be reliably suppressed.

[0120] Furthermore, a blocking portion 36 (multiple protrusions 36a) is formed only at the first end portion 30a of the support member 30. Therefore, the support member 30 can be made with a simple structure, and manufacturing costs can be reduced. .

[0121] Note that in Figure 12, the blocking portion 36 is formed only on the first end 30a side of the support member 30. However, it may also be formed on the second end portion 30b side. In this case, the projection amount of the blocking portion on the second end portion 30b side is equal to the projection amount (T) of the blocking portion 36 on the first end portion 30a side, or may be formed to be different from this projection 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 so as to be connected. When the projection amount of the blocking portion on the second end portion 30b side is equal to the projection amount (T) of the blocking portion 36 on the first end portion 30a side, the projection 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 projection amount of the blocking portion on the second end portion 30b side is different from the projection amount (T) of the blocking portion 36 on the first end portion 30a side, the projection amount of the blocking portion from the first end portion 30a side to the second end portion 30b side 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 to the second end portion 30b. In addition, 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, modified examples, variation examples or improvement examples from the content disclosed in this specification, and these are included in the technical scope described in the appended claims. 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.

[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. The axial length of the support member 30 is, for example, about 2.5 times the axial length of the aerosol-forming substrate 23. If the extension is doubled and the aerosol passing through the support member 30 can be sufficiently cooled, then the mouthpiece It is not necessary to include -40.

[0124] Furthermore, for example, in the smoking device cartridge 1 according to the first embodiment, the support member 30 is It may be made of resin molded product, and the outer surface of this resin molded product may have protrusions or recesses. It's okay if it's done.

[0125] Furthermore, in the first embodiment, the through hole 31a of the support member 30 extends along the central axis C1. A shaft portion may be provided. In this case, a retaining member that holds the shaft portion from the inner circumferential surface of the through hole 31a By providing this, the orientation of the shaft can be maintained.
