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

[0011] (First Embodiment) Figure 1 is a cross-sectional view of a cartridge 1 for a smoking device according to the first embodiment of the present invention. As described above, the smoking device cartridge 1 according to the first embodiment comprises a heated object 20 and a support 30 The heating element 20, the support 30, and the mouthpiece 40 are comprised of the heating element 20, the support 30, and the mouthpiece 40. They are arranged in a line along the central axis C1. The heated object 20, the support 30, and the mouthpiece are then arranged. 40 is wrapped and integrated with a sheet-like exterior member 10. The exterior member 10 is For example, it is made of paper.

[0012] Here, the smoking device cartridge 1 shown in Figure 1 has, for example, a diameter of 6.5 to 7.5 mm. The length is formed to be 40-60 mm. The heated object 20 has a length of 10-25 mm. Yes. Of course, the smoking device cartridge 1 may be formed in dimensions other than those specified.

[0013] The heated object 20 is wrapped with a sheet-like packaging material 25, which is the aerosol-forming substrate 23 that serves as the filler. It is formed in a cylindrical shape, with the aerosol-forming substrate 23 exposed at both ends. However, both ends of the heated object 20 are not covered by a lid member (for example, paper). The packaging member 25 is For example, it is made of paper, but the material is not limited as long as it is a sheet-like component. By directly wrapping the base material 23 with the outer material 10, the packaging material 25 can be omitted, or aerozo The lubricating substrate 23 may also be covered with a lid member.

[0014] 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.

[0015] 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 1.5:1 to 30:1. It is preferable that this be the case. Also, the length of the aerosol-forming substrate 23 is approximately the same as the length of the heated object 20. It is preferable that it be 1. An example of the dimensions of the aerosol-forming substrate 23 is that the longer side is 1.5 It measures 0.3 mm on the shorter side and 12 mm in length.

[0016] 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.

[0017] 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. In addition, the mouthpiece 40 is made of cellulose acetate which removes fine particles. It may include a filter, etc. in the water vapor and aerosol generated in the heated object 20. Some of the fine particles are filtered out by the filter in this mouthpiece 40.

[0018] The support 30 is a thin sheet-like material (for example, paper, polymer sheet, rubber sheet, metal sheet). It consists of a single axial member 31 formed into a cylindrical shape by winding (such as a rod). The axial direction (longitudinal direction) is positioned to align with the central axis C1 of the smoking device cartridge 1. Then, one end of the axial member 31 is in contact with the aerosol-forming substrate 23, and the other end is a mouthpiece. By contacting the 40, the axial movement of the aerosol-forming substrate 23 is restricted. This prevents the aerosol-forming substrate 23 from detaching from the heated object 20.

[0019] In this embodiment, the diameter of the axial member 31 is smaller than the diameter of the heated object 20, approximately 2 / 3. To that extent, an annular space S1 is formed between the outer circumferential surface of the shaft-shaped member 31 and the exterior member 10. This is done. This space S1 constitutes a channel through which aerosols flow. Note that the axial member 10 The diameter of 0 is arbitrary and may be approximately equal to the diameter of the heated object 20. In this case, space S1 In addition, the shaft-shaped member 100 is located inside the smoking device cartridge 1. It is sufficient if it is positioned roughly along the central axis C1, and even if it is positioned at a slight angle. That's fine.

[0020] Figure 2 is a cross-sectional view taken along line II-II in Figure 1, and Figure 3 is a perspective view of the support 30 (axial member 31). As shown in Figures 2 and 3, the axial member 31 is made by winding a sheet-like material in a spiral shape multiple times. It is formed in such a way that aerosols can pass through its interior. Specifically, the axis In a cross-section perpendicular to the axial direction of the axial member 31, the spirally formed flow channel 35 is located in the axial member It is formed uniformly along the axial direction of 31. The aerosol flows through this channel 35. It is cooled as it reaches mouthpiece 40.

[0021] Furthermore, the width W of the channel 35 is set to a size that prevents the aerosol-forming substrate 23 from passing through. This prevents the aerosol-forming substrate 23 from clogging the channel 35. For example, if the aerosol-forming substrate 23 is formed in powder form, the width W of the flow path 35 is air The average particle size should be smaller than that of the aerosol-forming substrate 23. When formed in the shape of a strip or a rod, the width W of the channel 35 is the aerosol-forming substrate. It just needs to be smaller than the longer side of the 23 cross-section.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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. .

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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 (capsules) The capsule 60) may be provided on the support 30 (see Figure 7B).

[0035] 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...

[0036] (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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] (How to use smoking accessory cartridges) This section explains how to use the smoking accessory cartridge 1. Figure 4 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 flows through the support 30 (flow channel 35 and air). The liquid flows through the mouthpiece 40 in the order of intervening (S1), and then into the smoker's mouth.

[0046] 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.

[0047] Since the support 30 is made up of an axial member 100 which is made by winding a thin sheet-like member in a spiral shape, The structure of the body 30 is simple and manufacturing costs can be reduced. Also, the shaft-shaped member 100 is The structure consists of a spiral-shaped member, and a spiral-shaped channel 35 is formed inside. Therefore, it does not have a thick outer periphery like the conventional technology described above (Patent Document 1). The end of member 100 (one side of the sheet-like member) is dispersed on the end surface of the aerosol-forming substrate 23. They come into contact. In other words, as in the conventional technology described above, the end of the aerosol-forming substrate has a support element. The outer periphery does not make local contact. Therefore, the aerosol is generated by heating the aerosol-forming substrate 23. The amount and flow of aerosols generated are suppressed. As a result, the aroma and taste of the aerosols are reduced. The quality improves. Also, as the aerosol passes through space S1 and the swirling channel 35 The aerosol is effectively cooled. In particular, the support 30 is constructed by winding a sheet-like material. Therefore, when the aerosol passes through the channel 35, contact between the aerosol and the sheet-like member occurs. The contact area is large. Therefore, the heat of the aerosol is exchanged with the sheet-like material, and air The rosol is effectively cooled. As a result, the smoker experiences a better aerosol draw.

[0048] Furthermore, the support 30 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40, Because the axial movement of the allosol-forming substrate 23 is restricted, the smoking device cartridge 1 is controlled. When inserting it into the smoke device 70, the position of the aerosol-forming substrate 23 is prevented from shifting. As a result, the heating of the aerosol-forming substrate 23 by the heating unit 75 becomes stable, and good aerosols are generated. Furthermore, by having a support 30, the smoking device cartridge 1 is connected to the smoking device. This prevents axial deformation when inserting into the 70.

[0049] Furthermore, if the diameter of the support 30 is made approximately equal to the diameter of the heated object 20, the outer surface of the support 30 Because the exterior member 10 is supported by this, the diameter when gripping the smoking device cartridge 1 with your fingers It can also prevent deformation in direction.

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

[0051] (Extreme variation 1-1) Figure 5 is a cross-sectional view of the support 30-1 according to modified example 1-1. Note that Figure 5 is the same as Figure 1 II- This is a cross-sectional view taken at the same position as line II. The axial member 31-1 shown in Figure 5 is a sheet-like material. The material is formed into a rectangular tube shape by spiraling it, and its cross-sectional outer shape is roughly rectangular. In the cross-section shown in Figure 5, a spiral-shaped channel 35-1 is formed.

[0052] Even with this configuration, the same effects and advantages as those of the first embodiment described above are achieved. The shape can be a square, or it can be a polygon such as a pentagon or hexagon.

[0053] (Variations 1-2) Figure 6 is a cross-sectional view of the support 30-2 according to modified example 1-2. Note that Figure 6 is the same as Figure 1 II- This is a cross-sectional view taken at the same position as line II. The axial member 31-2 shown in Figure 6 is sheet-like The material is formed into a triangular tube shape by spiraling it, and its cross-sectional shape is approximately an equilateral triangle. As shown in the cross-section in Figure 6, a spiral-shaped channel 35-2 is formed.

[0054] Even with this configuration, the same effects and advantages as those of the first embodiment described above are achieved. The shape can be an isosceles triangle, a right triangle, etc.

[0055] (Variations 1-3) Figure 7A shows the state of the support 30-3 before completion according to modified example 1-3, and Figure 7B shows the modified example. This is a perspective view (after completion) of the support 30-3 related to 1-3. In this example, as shown in Figure 7A. The rectangular sheet-like material is cut along the dotted line to form a trapezoidal sheet. Prepare a trapezoidal member. Then, with the shorter side as the center, move in the direction of the arrow in the diagram. As it is wound, a cone-shaped recess 37 is formed, as shown in Figure 7B.

[0056] Then, as shown in Figure 7B, the support 30-3 according to modified example 1-3 is formed at its end. A capsule 60 is provided in the recessed 37. This capsule 60 is designed to protect against aerosols. These substances alter the aroma and taste, and the various flavor additives mentioned above can be used. ru.

[0057] According to these modified examples 1-3, the capsule 60 is used to flavor the aerosol. This can improve the aroma and flavor. Also, you can crush or chew the 60 capsules by hand. By doing so, a deeper flavor can be achieved. Also, capsule 60 is supported by support 30-3 Because it is located inside, even if the smoking cartridge is subjected to vibration or shock, the capsule The impact is less likely to reach capsule 60. As a result, capsule 60 is prevented from rupturing and losing its flavor. Furthermore, since the capsule 60 is positioned roughly along the central axis C, the capsule 60 When crushed, the flavor additive spreads uniformly inside the support 30-3 and into the aerosol. They blend together, resulting in a deeper flavor.

[0058] (Second Embodiment) Next, a second embodiment of the present invention, a cartridge 2 for a smoking device, will be described. The smoking device cartridge 2 relating to the application form is a smoking device cartridge 1 according to the first embodiment and Although the basic structure is the same, the structure of the support differs. Therefore, in the following explanation, this This explanation will focus on the differences, and any explanations that overlap with the first embodiment will be omitted.

[0059] Figure 8 is a cross-sectional view of a smoking device cartridge 2 according to a second embodiment of the present invention, and Figure 9 is shown in Figure 8. This is a perspective view of the support 130. As shown in Figure 8, a cart for smoking devices according to the second embodiment. Ridge 2 comprises a heated object 20, a support 130, and a mouthpiece 40.

[0060] As shown in Figure 9, the support 130 is a thin sheet-like material (e.g., paper, polymer sheet). A single axial member formed into a cylindrical shape by spirally winding a material (such as a rubber sheet or a metal sheet). It consists of 131. Inside the axial member 131, there is a swirling channel 135 through which aerosols flow. It is formed such that the end portion 132 of the shaft-shaped member 131 decreases in diameter towards the tip. It is constructed by being stretched in the axial direction (longitudinal direction). As a result, the axial member 13 1 has some elasticity in the axial direction. The shaft-shaped member 131 has its axial direction as a smoking device car When positioned along the central axis C1 of the ridge 1, one end of the axial member 131 is aerosol-shaped The base material 23 is slightly pressed against the mouthpiece 40, and the other end 132 slightly presses against the mouthpiece 40. They come into contact in this manner. In this way, the axial movement of the aerosol-forming substrate 23 is restricted.

[0061] This configuration provides the same effects as the first embodiment, and the axial member 131 is an axis Because it has elasticity in the direction, the support of the aerosol-forming substrate 23 is further improved. Furthermore, when inserting the smoking device cartridge 2 into the smoking device 70, the aerosol-forming substrate 23 is added. It is possible that it is pressed by the heating element 75 and pushed out into the interior. The base material 23 presses the shaft-shaped member 131 in the axial direction. However, in this embodiment According to this, the end face of the shaft-shaped member 131 that faces the aerosol-forming substrate 23 is recessed, and the shaft Because it has elasticity in the direction, in response to the pressure from the aerosol-forming substrate 23, the end face The central part is displaced so as to move inward. As a result, the smoking device 70 of the smoking device cartridge 2 Insertion into it is smooth.

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

[0063] (Variation 2-1) Figure 10 is a perspective view of the support 130-1 according to modified example 2-1. The axial member shown in Figure 10 131-1 is a flexible sheet-like member (for example, PPS (polyphenylene sulfide) A thermoplastic resin such as filtrate or a thermosetting resin such as PI (polyimide) is wound in a spiral shape. A channel 135-1 through which an aerosol flows is formed inside the axial member 131-1. It is formed.

[0064] Even with this configuration, it is possible to apply elastic force in the axial direction of the support 130-1. This provides the same effects and advantages as the second embodiment described above.

[0065] (Variation 2-2) Figure 11 is a cross-sectional view of a smoking device cartridge 2 including a support 132-2 according to modified example 2-2. Figure 12 shows a state in which the support 132-2 of a smoking device cartridge has been displaced according to modified example 2-2. This is a cross-sectional view of edge 2.

[0066] As shown in Figure 11, the support 132-2 in the modified example 2-2 is a thin sheet-like member It consists of a single axial member 131-2 that is formed into a cylindrical shape by being wound in a spiral. Inside 1-2, a swirling channel 135-2 through which aerosols flow is formed. Then, when one end of the shaft-shaped member 131-2 is pushed in the axial direction, as shown in Figure 9, the inside of one end face The central part is concave, and the end on the other end is stretched. The shaft-shaped member 131-2 is in the axial direction. When the external force applied to it is released, it returns to its original shape. That is, the axial member 131-1 is elastic in the axial direction. It is configured to be deformable.

[0067] This configuration itself is the same as the axial member 31 shown in Figure 1, but the axial direction of the axial member 131-2 The length of the shaft member 131-2 is shorter than that of the shaft member 31. A space S1 is formed between -40. Also, the outer circumferential surface of the shaft-shaped member 131-2 is the exterior It is in contact with the inner circumferential surface of member 10. That is, the diameter of the support 130-2 and the diameter of the outer casing member 10. It is structured to be approximately equal to [the other].

[0068] This configuration provides the same effects as the second embodiment described above. Furthermore, the axial part The outer surface of material 131-2 prevents radial deformation of the exterior member 10.

[0069] Furthermore, when inserting the smoking device cartridge 2 into the smoking device 70, the aerosol forming substrate 23 Even when pressed by the heating section 75 and pushed inward, as shown in Figure 12, the axial shape The central part of member 131-2 is displaced so as to be recessed in the axial direction (dotted line in the figure), so the smoking device Insertion of cartridge 2 into smoking device 70 is smooth.

[0070] (Third embodiment) Next, a third embodiment of the present invention, a cartridge 3 for a smoking device, will be described. The smoking device cartridge 3 relating to the application form is a smoking device cartridge 1 according to the first embodiment and Although the basic configuration is the same, the main difference lies in the number of support structures. Therefore, in the following explanation, This explanation will focus on the differences between the two embodiments, and any explanations that overlap with the first embodiment will be omitted.

[0071] Figure 13 shows a support 23 used in a smoking device cartridge 3 according to the third embodiment of the present invention. This is a cross-sectional view of point 0. Note that Figure 13 is a cross-sectional view taken at the same position as line II-II in Figure 1. As shown in Figure 13, in this embodiment, the support 230 has two axial members 231 It consists of the following. The shaft-shaped member 231 is configured in the same way as the shaft-shaped member 31 according to the first embodiment. The shaft-shaped member 231 is formed into a cylindrical shape by winding a thin sheet-like material in a spiral shape, and inside The channel 235 through which the aerosol flows is formed in a spiral shape. And there are two axial members 23 1 is bundled together by a sheet-like binding member 15. The binding member 15 is, for example It is made of paper, but rubber components or film sheets may also be used.

[0072] This configuration provides the same effects as the first embodiment. Furthermore, two axial members Since 231 is bundled and integrated with the binding member 15, handling of the support 230 is easy. It is easy. Therefore, the heated object 20, the support 230, and the mouthpiece 40 are connected to the outer casing member 1 The winding process becomes easier with 0. Also, the support 230 is composed of two axial members 231. Therefore, the rigidity of the support 230 is increased, and the axial deformation of the smoking device cartridge 3 is reduced. This further prevents damage. Furthermore, the number of shaft-shaped members 231 is not limited to two; even if there are three or more, good.

[0073] Next, a modified example of the smoking device cartridge 3 according to the third embodiment will be described.

[0074] (Variation 3-1) Figure 14 is a cross-sectional view of the support 230-1 according to modified example 3-1. Note that Figure 14 is the same as Figure 1. This is a cross-sectional view taken at the same position as line II-II. Support 230-1 shown in Figure 14 is 2 The configuration consists of two axial members 231 and 232 bundled together with a binding member 15 to form a single unit, The axial member 231 and the axial member 232 have cross-sectional shapes (outer shape) perpendicular to the axial direction (longitudinal direction). ) are different. Specifically, the axial member 231 has a roughly circular cross-sectional shape (see Figure 2) In contrast, the axial member 232 has a roughly triangular cross-sectional shape (see Figure 6). Even when configured in this way, it produces the same effects as the third embodiment. Note that the shaft-shaped member 231 and the shaft The cross-sectional outer shapes of the shaped members 232 do not need to be different from each other, and the round shape and triangular shape shown in Figure 14 are not required. Not limited to combinations.

[0075] (Variation 3-2) Figure 15 is a cross-sectional view of the support 230-2 according to modified example 3-2. Note that Figure 15 is the same as Figure 1. This is a cross-sectional view taken at the same position as the line II-II. The support 230-2 shown in Figure 15 is 2 It is consistent with the third embodiment in that it has two axial members 231, but with two axial members 231 The configuration in which they are bundled is different. Specifically, in this example, one of the axial members 231 (left side) The axial member (the first one) is wrapped with the binding portion 231a, which is part of the other axial member 231 (the right-side axial member). Then, the end portion 231b of this fastening portion 231a is bonded to the outer circumferential surface of the other shaft-shaped member 231. Two axial members 231 are bundled together. Even with this configuration, the same operation as in the third embodiment can be performed. This provides an effective solution. Furthermore, in this example, since the binding member 15 is unnecessary, the number of parts can be reduced. There is a dot.

[0076] In this example, one shaft-shaped member 231 is wrapped with the binding portion 231a of the other shaft-shaped member. I explained the bundling configuration, but one sheet-like material is wound spirally from both ends to form two It is also possible to form an axial member. Even in this configuration, the binding member 15 is used. Since the two axial members are integrated without any need for separate parts, handling is easy, and the number of parts is small. This can also be reduced.

[0077] The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention. It is possible to make it into a form, and all the technical matters included in the technical concept described in the claims are included in this. This is the subject of the invention. The above embodiments are shown as preferred examples, but those skilled in the art will understand this Based on the information disclosed in the specification, various alternatives, modifications, variations, or improvements can be realized. These can be achieved, and these fall within the technical scope described in the attached claims.

[0078] For example, the sheet-like members constituting the axial members 31, 131, and 231 are as described above. Any of the following materials can be used: paper, polymer sheets, rubber sheets, metal sheets, resin sheets, etc. While this is possible, if you want to enhance the cooling effect of the aerosol, it is recommended to use a metal sheet. Furthermore, if a shape memory alloy is used as a sheet-like component, its shape becomes stable, thus aerozo The lubrication base material 23 can be well supported.

[0079] Furthermore, the above-mentioned flavor is used as a sheet-like material constituting the axial members 31, 131, and 231. Components impregnated or printed with additives can be used. In these cases, aerosols are used. Without changing the raw materials of the forming substrate 23, the axial members 31, 131, and 231 are impregnated or printed. By simply changing the flavor additives, you can easily increase the variety of aromas and flavors. Microcapsules containing flavor additives are supported on the axial members 31, 131, and 231. However, it produces a similar effect.

[0080] Furthermore, if the support 230 is configured to include multiple axial members 231 (see, for example, Figure 13), each The flavor additive impregnated into the shaft-shaped member 231 may be different. Different flavors are added to allosol, improving its aroma and taste.

[0081] Furthermore, the sheet-like material constituting the axial members 31, 131, and 231 is porous, All kinds of materials can be used, including those with embossed surfaces.

[0082] Furthermore, although the embodiments of the present invention have been described using the case where there are two axial members 231 as an example, In this context, the number of axial members is not limited. That is, there may be three or more axial members. .

[0083] Furthermore, the axial members 31, 131, and 231 are not necessarily made by winding thin sheet-like material in a spiral shape. It is not necessary to have such a configuration. As long as the aerosol-forming substrate 23 can be supported, for example, It may also be a hollow cylindrical body formed by winding a tapered member around once.

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

[0085] The shape of the aerosol-forming substrate 23 can be, for example, rod-shaped, granular, powder-shaped, strip-shaped, or sheet-shaped. Rolled up, folded sheet, fibrous, crimped sheet, crimped fibers Formed into chunks, flakes, viscous, highly viscous clay-like, gel-like, slime-like, tablet-like Examples include paste-like forms. These forms may be mixed with one or more of them. It can be used while present.

[0086] Furthermore, the shape of the aerosol-forming substrate 23 may be, for example, a strand or a porous form. This may also be done. To make it porous, for example, the dried sheet is repeatedly punctured with multiple needles. It can be formed by piercing or other methods (other methods may also be used).

[0087] The shape of the powdery or granular aerosol-forming substrate 23 may be, for example, granules, pellets, etc. It's good in terms of form as well.

[0088] The powdered or granular aerosol-forming substrate 23 may be solidified into a block or slightly hydrated. Alternatively, you can add oil to make a paste. [Explanation of symbols]
