Description

[Technical field]

[0001] The present invention relates to a cartridge for a smoking article. [Background technology]

[0002] In recent years, tobacco products that use a method of heating a tobacco cartridge containing tobacco ingredients and inhaling the vaporized tobacco ingredients without using a flame have become widely known. In addition, due to the diversification of tastes, cartridge products that allow users to enjoy the aroma and flavor of plants that do not contain tobacco ingredients without using a flame, just like tobacco, are becoming known.

[0003] For example, Patent Document 1 states that "a smoking article for use in an aerosol-generating device includes an aerosol-forming substrate located at the most upstream end of the smoking article and a support element located immediately downstream of the aerosol-forming substrate. The support element abuts the aerosol-forming substrate, and the aerosol-forming substrate is configured to be penetrable by a heating element of the aerosol-generating device having a diameter between about 40 percent and about 70 percent of the diameter of the aerosol-forming substrate without substantially deforming the smoking article. The support element is configured to resist downstream movement of the aerosol-forming substrate during insertion of the heating element of the aerosol-generating device into the aerosol-forming substrate" (see Abstract).

[0004] [Patent Document 1] Special Publication No. 2015-519915 Summary of the Invention [Problem to be solved by the invention]

[0005] The support element (support body) described in Patent Document 1 is a resin molded product having a hollow structure, and therefore manufacturing the support element is time-consuming and there is room for improvement.

[0006] The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a support, which is a part of a cartridge for a smoking article, having a new structure that is not based on resin molding. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, one aspect of the present invention is a cartridge for a smoking device comprising an aerosol-forming substrate, a mouthpiece arranged coaxially with the aerosol-forming substrate, and a support arranged between the aerosol-forming substrate and the mouthpiece and supporting the aerosol-forming substrate, wherein the support is composed of a plurality of granular materials, and an aerosol generated by heating the aerosol-forming substrate can pass through gaps between the plurality of granular materials. Effect of the Invention

[0008] According to the present invention, the support body, which is a part of the cartridge for a smoking article, can have a new structure that is not based on resin molding. Note that problems, configurations and effects other than those described above will become apparent from the description of the embodiments below. [Brief description of the drawings]

[Figure 6] FIG. 11 is a cross-sectional view of a cartridge for a smoking article according to a third embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

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

[0011] (First embodiment) Fig. 1 is a cross-sectional view of a smoking article cartridge 1 according to a first embodiment of the present invention. As shown in Fig. 1, the smoking article cartridge 1 according to the first embodiment includes a heated object 20, a support 30, and a mouthpiece 40. The heated object 20, the support 30, and the mouthpiece 40 are arranged side by side on a central axis C1. The heated object 20, the support 30, and the mouthpiece 40 are integrated by being wrapped around by a sheet-like exterior body 10. The exterior body 10 is made of, for example, paper.

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

[0013] The heated object 20 is formed into a cylindrical shape by wrapping the aerosol-forming substrate 23, which is a filling material, in a sheet-like packaging material 25, and the aerosol-forming substrate 23 is exposed at both ends. That is, both ends of the heated object 20 are not covered with a lid member (e.g., paper). The packaging material 25 is made of, for example, paper, but any material may be used as long as it is a sheet-like member.

[0014] The aerosol-forming substrate 23 is made of a smoking material made from a tobacco plant or a non-tobacco plant, which will be described in detail later. The aerosol-forming substrate 23 is made of, for example, a bundle of rectangular members, and is arranged so that the longitudinal direction of the bundle is aligned with the central axis C1.

[0015] When the aerosol-forming substrate 23 is made of a strip-shaped member, the cross section perpendicular to the central axis C1 is substantially rectangular, and the ratio of the long side to the short side of the cross section is preferably, for example, in the range of 1.5:1 to 30:1. The length of the aerosol-forming substrate 23 is preferably substantially the same as the length of the heated body 20. As an example of the dimensions of the aerosol-forming substrate 23, the long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

[0016] Of course, the aerosol-forming substrate 23 is not limited to a strip-shaped member. For example, it may be a rod-shaped member or a powder-shaped member. The aerosol-forming substrate 23 may be configured to be a combination of a strip-shaped member and a powder-shaped member, a combination of a strip-shaped member and a rod-shaped member, a combination of a rod-shaped member and a powder-shaped member, or a combination of a strip-shaped member, a rod-shaped member and a powder-shaped member. In these cases, it is preferable to use at least a part of the raw materials of each member that are different, since this improves the aroma and taste.

[0017] The mouthpiece 40 is a part that constitutes the mouthpiece of the cartridge 1 for a smoking device, and is made of, for example, paper. The mouthpiece 40 may also include a cellulose acetate filter that removes fine particles. Some of the fine particles in the water vapor and aerosol generated by the heated body 20 are filtered by the filter of the mouthpiece 40.

[0018] The support 30 is composed of a plurality of granular materials 31. The granular materials 31 are made of, for example, plastic particles, and are filled inside the exterior body 10 sandwiched between the aerosol-forming substrate 23 and the mouthpiece 40. The shape of the granular materials 31 is not particularly limited, and the cross-sectional shape may be, for example, a circle, an ellipse, or a polygon. The granular materials 31 may be solid or hollow, and the particle size thereof is, for example, 0.5 mm to 1 mm.

[0019] The granular materials 31 are not limited to plastic particles, but may be particles made of activated carbon capable of removing specific chemical substances (e.g., tar) mixed into the aerosol, or particles made of inorganic materials such as ceramics or glass, or may be a mixture of a plurality of types of particles. Furthermore, a remover (e.g., chitosan) capable of removing the above-mentioned chemical substances (e.g., aldehydes such as formaldehyde) may be added to a part or all of the plurality of granular materials 31.

[0020] Alternatively, plant-based materials such as coffee bean grounds after coffee extraction or used tea leaves after tea leaves are extracted can be used as the granular materials 31. These plant-based materials are porous and have a high deodorizing effect, so that the support 30 with deodorizing effect can be realized. When the plurality of granular materials 31 are made of coffee bean grounds, it is preferable to use them in a dumpling-like state with starch or the like, since the particle size of the coffee bean grounds is small as it is. When the plurality of granular materials 31 are made of used tea leaves, if the aerosol-forming substrate 23 is made of used tea leaves, both the aerosol-forming substrate 23 and the support 30 can be manufactured from the same material.

[0021] The support 30 is a porous structure having gaps S between the multiple granular materials 31. The gaps S function as a passage for the aerosol generated by heating the aerosol-forming substrate 23. One end 30a of both ends of the support 30 faces one end 23a of the aerosol-forming substrate 23, and the other end 30b faces the mouthpiece 40. When a heating member is inserted, the one end 30a of the support 30 abuts against the aerosol-forming substrate 23 to support it, and the other end 30b of the support 30 abuts against the mouthpiece 40 to support it.

[0022] Fig. 2 is a cross-sectional view taken along line II-II in Fig. 1. As shown in Fig. 2, at an end 30a of the support 30 facing the aerosol-forming substrate 23, a plurality of granular materials 31 are bonded together using an adhesive 32. Therefore, the strength of the end 30a of the support 30 facing the aerosol-forming substrate 23 is increased, and the end 23a of the aerosol-forming substrate 23 can be firmly supported even when a heating member is inserted.

[0023] In addition, not only one end 30a of the support 30, but also the other end 30b and the multiple granular materials 31 arranged on the outer peripheral surface side may be partially bonded together. Also, as long as the necessary support strength of the aerosol-forming substrate 23 is ensured, it is not necessary to bond all of the granular materials 31. Furthermore, all of the granular materials 31, including the granular materials 31 on the aerosol-forming substrate 23 side, may be bonded together, and in this way, the overall strength of the support 30 can be increased. In this case, if all of the gaps S between the granular materials 31 are filled with adhesive, the porous structure of the support 30 will be damaged, so it is necessary to bond them while ensuring the gaps S that allow the aerosol to pass through.

[0024] Next, a description will be given of specific examples of raw materials used as the aerosol-forming substrate 23. The aerosol-forming substrate 23 is composed of any one or a combination of the following raw materials.

[0025] The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant. Examples of tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. Examples of non-tobacco plants include plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (scale roots, tuberous roots, etc.), stems, tubers, skin (stem skin, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches, etc.

[0026] In this specification, "plants" refers to a group of animals, and includes not only living organisms that have roots and live in a fixed location, such as grass and trees, but also algae such as microalgae and seaweed, and fungi such as mushrooms.

[0027] The aerosol-forming substrate 23 is prepared, for example, by mixing a dried and pulverized non-tobacco plant with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, binders, thickeners, etc., and pulverizing or classifying the mixture into powder or granules, or forming the mixture into a paste. The aerosol-forming substrate 23 is also formed into a sheet, which is then cut into a strip or rod shape having a predetermined width and length.

[0028] For example, when the part of the non-tobacco plant is a leaf, teas can be preferably used. Not only do different plants produce different teas, but even the same plant can produce different teas depending on the processing method. Specific examples include Japanese tea, black tea, Angelica keiskei tea, sweet tea, Gynostemma pentaphyllum tea, aloe tea, ginkgo leaf tea, oolong tea, turmeric tea, Quercus salicina tea, Eleuthero tea, plantain tea, kakiodoshi tea, persimmon leaf tea, chamomile tea, chamomile tea, Kawara Kesmei tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, wolfberry tea, soft leaf tea, black bean tea, gennoshoko tea, brown rice tea, burdock tea, comfrey tea, bifu tea, cherry blossom tea, Examples include saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, ginger tea, horsetail tea, Japanese laurel tea, swertia tea, buckwheat tea, taranoki tea, dandelion tea, sweet tea, Houttuynia tea, Eucommia tea, sword bean tea, elderberry tea, ratwort tea, Job's tears tea, Habu tea, loquat leaf tea, Pu-erh tea, safflower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea, eucalyptus tea, monk fruit tea, rooibos tea, and bitter melon tea. For these teas, tea leaves after drinking may be used. Using tea leaves allows expensive tea to be reused and put to good use.

[0029] Furthermore, extracts of the above-mentioned non-tobacco plants, so-called extracts and processed products, can also be used. The extracts may be in the form of liquid, starch syrup, powder, granules, solution, etc.

[0030] Examples of the aerosol former as the raw material of the aerosol-forming substrate 23 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, dimethyl tetradecanedione, etc. Among them, glycerin and propylene glycol are preferable.

[0031] The microcrystalline cellulose used as the raw material for the aerosol-forming substrate 23 is obtained, for example, by partially depolymerizing α-cellulose obtained from the pulp of a fibrous plant with an acid, and is obtained by removing the soluble portion from the cellulose and, if necessary, crystallizing the insoluble portion.

[0032] The microcrystalline cellulose may be in the form of a powder or may be dispersed in a solvent such as water to form a suspension. In this case, dispersion in the solvent can be performed using a high-speed stirrer or a high-pressure homogenizer.

[0033] Furthermore, if necessary, a flavor additive that adds flavor is preferably used as a raw material for the aerosol-forming substrate 23. Examples of the flavor additive include mint, cocoa, coffee, and black tea extracts, and powder of catechins from tea extracts. Preservatives that are used in foods are preferable, and examples of the preservatives include sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

[0034] The aerosol-forming substrate 23 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinyl polypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to that obtained from natural products, and may be a synthetic product. In addition, peppermint, mint, peppermint oil, and other menthol-containing substances may be used.

[0035] The flavor additive is provided in the mouthpiece 40, for example, by impregnating the wall of the mouthpiece 40. The manner in which the flavor additive is provided in the mouthpiece 40 is not limited to this manner, and for example, the flavor additive may be provided in the mouthpiece 40 by embedding a capsule in which the flavor additive is encapsulated in the wall of the mouthpiece 40. Alternatively, a capsule in which the flavor additive is encapsulated may be disposed between the mouthpiece 40 and the heated body 20. When the flavor additive is encapsulated in a capsule, the smoker can break the capsule by pressing it with his or her finger, and the aromatic component of the flavor additive can be volatilized at a desired timing.

[0036] Furthermore, when the flavor additive is, for example, encapsulated in a microcapsule, the encapsulated microcapsule may be provided on the heated body 20. Of course, the microcapsule may be provided on the support 30.

[0037] Binders or thickeners as raw materials for the aerosol-forming substrate 23 include gums such as guar gum, xanthan gum, gum arabic and locust bean gum, cellulose binders such as hydroxypropyl cellulose, carboxymethylcellulose, hydroxyethylcellulose, methylcellulose and ethylcellulose, polysaccharides such as starch, organic acids such as alginic acid, sodium alginate, sodium carboxymethylcellulose, caranagin, agar and conjugate base salts of organic acids such as pectin, and combinations thereof.

[0038] (Method of manufacturing an aerosol-forming substrate) Each step of the manufacturing method of the aerosol-forming substrate 23 will be described below. The manufacturing process of the aerosol-forming substrate 23 includes a drying / grinding step of drying / grinding a tobacco plant or a non-tobacco plant as a main raw material and weighing the same, a preparation step of pretreating and weighing the other raw materials, a mixing step of mixing the raw materials to form a composition, and a filler molding step of molding the composition.

[0039] In the drying and grinding process, the parts of the tobacco plant or non-tobacco plant that are the main raw material (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) that are used are processed into a specific ground material to make a composition. At that time, it is preferable to adjust the moisture content to a level that is convenient for absorbing or carrying the aerosol former, water, and other components that are added later. In drying, the temperature is preferably 60°C or higher and 80°C or lower. By setting it in this range, it is easy to reach the desired moisture content while avoiding the dissipation of the required flavor components. Furthermore, the drying and grinding process can also be provided with a sieving process to sieve the ground material, and it can be adjusted to the desired particle size before being fed into the mixing process.

[0040] In the preparation step, it is possible to prepare raw materials necessary for producing the aerosol-forming base material 23. The above-mentioned microcrystalline cellulose is weighed in the preparation step and is then put into the mixing step.

[0041] In the mixing step, a conventional mixer can be used. For example, a mixing device in which the raw materials in a mixing vessel are mixed while applying a shear force with an agitating blade is preferably used.

[0042] In the filling forming step, a composition in which various raw materials are mixed is formed into a thin sheet, which is then cut to form a strip-shaped or rod-shaped aerosol-forming substrate 23. In this embodiment, a plurality of roll mills are prepared to form a thin sheet. When a plurality of roll mills are used, it is possible to form a sheet of a desired thickness using a doctor blade while performing kneading, dispersion, etc. by compression due to being forced between narrow rolls and shearing due to the difference in roll speed, which is preferable. It can also be produced using a press roller or a press machine.

[0043] To obtain a powdered or granular aerosol-forming substrate 23, it is preferable to pulverize or classify the composition as appropriate. The average particle diameter of the powdered or granular aerosol-forming substrate 23 is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less. The average particle diameter is determined, for example, by a sieving method described in JIS K 0069:1992. That is, the average particle diameter is the diameter equivalent to 50% of the mass obtained by integrating the mass from the larger openings in the test results using multiple sieves. The particle diameter at 50% of the integrated value in the particle size distribution determined by a laser diffraction / scattering method may also be used as the average particle diameter.

[0044] In the filling forming step, other means may be used, such as passing the composition through an orifice under pressure to form the composition. In addition, in the filling forming step, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, water, etc. may be added as necessary.

[0045] The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut to a predetermined width by a cutter, a rotary cutter using a rotary blade, or the like.

[0046] Here, when the surface of the aerosol-forming substrate 23 is given adhesiveness, any means capable of giving adhesiveness may be used, but the above-mentioned binder may be attached to at least a part of the surface. By giving adhesiveness, when the strip-shaped or rod-shaped aerosol-forming substrate 23 is combined with the powder-shaped, granular or pasty aerosol-forming substrate 23, the powder-shaped, granular or pasty aerosol-forming substrate 23 can be stably held on the surface of the strip-shaped or rod-shaped aerosol-forming substrate 23.

[0047] (How to use smoking cartridges) A method of using the cartridge 1 for a smoking tool will be described. FIG. 3 is a cross-sectional view of the cartridge 1 for a smoking tool inserted into a smoking tool 70. The cartridge 1 for a smoking tool is attached to a heating type smoking tool 70 for use. The smoking tool 70 has an insertion section 72 for inserting the cartridge 1 for a smoking tool. A needle-shaped or blade-shaped heating section 75 is provided in the insertion section 72. When the cartridge 1 for a smoking tool is inserted into the insertion section 72, the heating section 75 generates heat, and an aerosol is generated from the aerosol-forming substrate 23. When a smoker holds the mouthpiece 40 in his / her mouth and inhales in this state, the aerosol flows through the gap S of the support 30 and the mouthpiece 40, and then flows into the smoker's mouth.

[0048] The cartridge 1 for a smoking article according to the first embodiment configured as above can provide the following effects.

[0049] Since the support 30 is composed of a plurality of granules 31, the production is simpler than that of conventional resin molded products, and the production cost of the support 30 can be reduced.

[0050] In addition, the support 30 is a porous structure having gaps S between the multiple granular materials 31, and the gaps S function as flow paths for the aerosol, so that the aerosol is cooled while being rectified by the gaps S, thereby improving the aroma and taste of the aerosol.

[0051] Furthermore, since the plurality of granular materials 31 are disposed between the aerosol-forming substrate 23 and the mouthpiece 40, and the plurality of granular materials 31 disposed on the side facing the aerosol-forming substrate 23 are bonded together, the end 23a of the aerosol-forming substrate 23 can be firmly supported. Note that not only one end 30a of the support 30, but also the other end 30b and the plurality of granular materials 31 disposed on the outer circumferential surface side may be partially bonded together, or all of the granular materials 31 may be bonded together.

[0052] Second embodiment Next, a smoking article cartridge according to a second embodiment will be described. The smoking article cartridge 2 according to the second embodiment has basically the same configuration as the smoking article cartridge 1 according to the first embodiment, but differs in that the support 30 is composed of a mixture of a first granular material 33 and a second granular material 34. Therefore, the following description will focus on this difference, and descriptions that overlap with the first embodiment will be omitted.

[0053] Fig. 4 is a cross-sectional view of a cartridge 2 for a smoking article according to the second embodiment. As shown in Fig. 4, the support 30 is composed of a first granular material 33 made of plastic particles or the like, and a second granular material 34 made of a capsule. In Fig. 4, the first granular material 33 is shown in white, and the second granular material 34 is hatched, so that the first granular material 33 and the second granular material 34 can be easily distinguished from each other.

[0054] The first granular material 33 is made of plastic particles or inorganic materials, similar to the granular material 31 constituting the support 30 of the cartridge 1 for a smoking article according to the first embodiment. The second granular material 34 is made of a capsule in which a flavor additive is enclosed within a shell layer. The shell layer of the capsule is configured to melt with heat when heated and release the flavor additive inside to the outside, but the flavor additive inside may be released to the outside by crushing it by hand. The flavor additive enclosed in the capsule of the second granular material 34 includes smoking taste components such as flavoring components and tea leaves, and may also include tar removal components, aerosol formers, etc.

[0055] The shape of the second granular material 34 is not particularly limited, and may be a sphere, polygonal shape, or the like, but is preferably a capsule having a similar shape to the first granular material 33. The mixing ratio of the first granular material 33 and the second granular material 34 is not particularly limited, but since the second granular material 34 has a structure that melts when heated, it is preferable that the second granular material 34 contains at least half of the first granular material 33.

[0056] The cartridge 2 for a smoking article according to the second embodiment thus configured can achieve the same effects as those of the first embodiment described above. In addition, of the first granular material 33 and the second granular material 34 constituting the support 30, the second granular material 34 is made of a capsule containing a flavor additive, and this capsule is configured to melt with heat when heated and release the flavor additive inside to the outside. Therefore, when smoking, the flavor additive enclosed in the capsule of the second granular material 34 mixes with the first granular material 33, allowing the user to enjoy a new flavor or aroma, or a complex flavor or aroma.

[0057] Next, a modified example of the cartridge 2 for a smoking article according to the second embodiment will be described.

[0058] (Modification) Fig. 5 is a cross-sectional view of a smoking article cartridge 2-1 according to a modified example inserted into a smoking article 70. As shown in Fig. 5, the smoking article cartridge 2-1 according to the modified example has a shorter axial dimension of the aerosol-forming substrate 23, but other configurations are the same as the smoking article cartridge 2 according to the second embodiment shown in Fig. 4.

[0059] When the cartridge 2-1 for a smoking article according to the modification is inserted into the heated smoking article 70, the heating portion 75 penetrates the short aerosol-forming substrate 23 and enters the inside of the support 30, so that the first granular material 33 and the second granular material 34 constituting the support 30 come into contact with the heating portion 75. When the heating portion 75 generates heat in this state, the capsule of the second granular material 34 is dissolved by the heat of the heating portion 75, and the flavor additive therein is released to the outside. In the cartridge 2-1 for a smoking article according to the modification configured in this manner, the heat of the heating portion 75 is directly transmitted to the second granular material 34 consisting of a capsule, so that the capsule of the second granular material 34 can be dissolved more reliably.

[0060] Third embodiment Next, a description will be given of a cartridge for a smoking article according to a third embodiment. The cartridge for a smoking article 3 according to the third embodiment has basically the same configuration as the cartridge for a smoking article 1 according to the first embodiment, but differs in that the support 30 has a cylindrical member in which a plurality of granular materials 31 are filled.

[0061] Fig. 6 is a cross-sectional view of a cartridge 3 for a smoking article according to a third embodiment. As shown in Fig. 6, the support 30 has a cylindrical member 35 covered with an exterior body 10, and a plurality of granular materials 31 are filled inside the cylindrical member 35. The cylindrical member 35 is formed into a cylindrical shape by rolling up a sheet-like member made of paper, for example, but may be made of a material other than paper. The cylindrical member 35 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40, and abuts against an end face of the packaging member 25 that covers the aerosol-forming substrate 23, thereby restricting the axial movement of the aerosol-forming substrate 23.

[0062] The cartridge 3 for a smoking article according to the third embodiment configured in this manner can achieve the same effects as those of the first embodiment described above. In addition, since the support 30 has a cylindrical member 35 that is filled with a plurality of granular materials 31, and this cylindrical member 35 restricts the axial movement of the aerosol-forming substrate 23, the position of the aerosol-forming substrate 23 is prevented from shifting when the cartridge 3 for a smoking article is inserted into the smoking article 70. In addition, since the exterior body 10 is supported by the outer peripheral surface of the cylindrical member 35, radial deformation can be prevented when the cartridge 3 for a smoking article is grasped with fingers.

[0063] The present invention is not limited to the above-mentioned embodiment, and various modifications are possible without departing from the gist of the present invention, and all technical matters included in the technical ideas described in the claims are the subject of the present invention. The above-mentioned embodiment shows a preferred example, but a person skilled in the art can realize various alternatives, modifications, variations, or improvements from the contents disclosed in this specification, and these are included in the technical scope described in the attached claims.

[0064] For example, in the cartridge 3 for smoking articles according to the third embodiment, the plurality of granular materials 31 filled in the cylindrical member 35 is not particularly limited, and may be made of a single type of material such as plastic particles or inorganic material as in the first embodiment, or may be a mixture including a capsule as in the second embodiment. Moreover, the cylindrical member 35 in which the plurality of granular materials 31 are filled and the packaging member 25 that covers the aerosol-forming substrate 23 do not necessarily need to be separate bodies, and may be integrally formed. Moreover, the plurality of granular materials 31 may be stored in a storage member such as a case in advance, and the storage member may be wrapped in the cylindrical member 35, or, if the cylindrical member 35 is omitted, the storage member may be wrapped in the exterior body 10. Furthermore, the packaging member 25 and the cylindrical member 35 may be omitted, and the aerosol-forming substrate 23, the plurality of granular materials 31, and the mouthpiece 40 may be wrapped in the exterior body 10. In this case, after wrapping the aerosol-forming substrate 23 in the outer casing 10, a plurality of granular materials 31 are dropped into the inside of the outer casing 10, and finally the mouthpiece 40 is inserted into the outer casing 10 to manufacture a cartridge for a smoking device.
