Description

The present invention relates to a cartridge for a smoking article.

In recent years, tobacco products that do not use a flame but heat a tobacco cartridge containing tobacco ingredients and inhale the vaporized tobacco ingredients have become widely known. In addition, due to the diversification of tastes, cartridge products that allow you to enjoy the aroma and flavor of plants that do not contain tobacco ingredients, without using a flame like tobacco, are also becoming known.

For example, Patent Document 1 describes 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).

Special Publication No. 2015-519915

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

The present invention was made in consideration of these circumstances, and its purpose is to provide a new structure for the support body, which is part of a cartridge for a smoking article, that is not made of resin.

In order to achieve the above 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, the support being made of a plurality of granular materials, and the aerosol generated by heating the aerosol-forming substrate can pass through the gaps between the plurality of granular materials.

According to the present invention, the support body, which is part of the cartridge for a smoking article, can be made into a new structure that is not based on resin molding. Note that the problems, configurations, and effects other than those described above will become clear from the description of the embodiment below.

Cross-sectional view of FIG. 2 is a cross-sectional view of the smoking article cartridge shown in FIG. 1 inserted into the smoking article. FIG. 6 is a cross-sectional view of a cartridge for a smoking article according to a second embodiment. FIG. 11 is a cross-sectional view showing a modified example of the cartridge for a smoking article according to the second embodiment. FIG. 11 is a cross-sectional view of a cartridge for a smoking article according to a third embodiment.

The following describes an embodiment of the present invention with reference to the drawings.

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 body 20, a support body 30, and a mouthpiece 40. The heated body 20, the support body 30, and the mouthpiece 40 are arranged side by side on a central axis C1. The heated body 20, the support body 30, and the mouthpiece 40 are wrapped and integrated by a sheet-like exterior body 10. The exterior body 10 is made of, for example, paper.

The smoking article cartridge 1 shown in FIG. 1 is formed, for example, with 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 smoking article cartridge may be formed with other dimensions.

The heated object 20 is formed into a cylindrical shape by wrapping the aerosol-forming substrate 23, which is the filler, in a sheet-like packaging material 25, and the aerosol-forming substrate 23 is exposed at both ends. In other words, 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 can be used as long as it is a sheet-like member.

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

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 in the range of, for example, 1.5:1 to 30:1. In addition, it is preferable that the length of the aerosol-forming substrate 23 is substantially the same as the length of the heated body 20. An example of the dimensions of the aerosol-forming substrate 23 is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm.

Of course, the aerosol-forming substrate 23 is not limited to a strip-shaped member. For example, it may be a rod-shaped member or a powder-shaped member. The aerosol-forming substrate 23 may also be configured as a combination of a strip-shaped member and a powder-shaped member, a strip-shaped member and a rod-shaped member, a rod-shaped member and a powder-shaped member, or 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, as this improves the aroma and taste.

The mouthpiece 40 is a part that constitutes the mouthpiece of the smoking device cartridge 1, 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 this mouthpiece 40.

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 may be, for example, a circular, elliptical, or polygonal cross-sectional shape. The granular materials 31 may be solid or hollow, and have a particle size of, for example, 0.5 mm to 1 mm.

The granular material 31 is 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 inorganic materials such as ceramics or glass, or may be a mixture of multiple 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 some or all of the multiple granular materials 31.

Alternatively, plant-based materials such as coffee bean grounds left over after coffee extraction or used tea leaves left over after tea leaves are extracted can be used as the granular material 31. These plant-based materials are porous and have a high deodorizing effect, so it is possible to realize a support 30 with a deodorizing effect. When the multiple 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 when left as is. When the multiple 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.

The support 30 is a porous structure having gaps S between the multiple granular materials 31. The gaps S function as a passageway for the aerosol generated by heating the aerosol-forming substrate 23. One end 30a of the two 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, one end 30a of the support 30 abuts against and supports the aerosol-forming substrate 23, and the other end 30b of the support 30 abuts against and supports the mouthpiece 40.

Figure 2 is a cross-sectional view taken along line II-II of Figure 1. As shown in Figure 2, at the end 30a of the support 30 facing the aerosol-forming substrate 23, multiple granules 31 are bonded together using adhesive 32. This increases the strength of the end 30a of the support 30 facing the aerosol-forming substrate 23, and allows the end 23a of the aerosol-forming substrate 23 to be firmly supported even when a heating member is inserted.

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, if the required 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, which can increase the overall strength of the support 30. 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.

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

The aerosol-forming substrate 23 is made from tobacco plants or non-tobacco plants. 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.

In this specification, "plants" refers to a group of organisms, as opposed to animals, and includes not only 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.

The aerosol-forming substrate 23 is prepared, for example, by mixing aerosol formers that generate aerosols, microcrystalline cellulose, additives that add flavor, preservatives, binders, thickeners, etc. with dried and crushed non-tobacco plants as appropriate, and then crushing or classifying the mixture into powder or granules, or forming it into a paste. The aerosol-forming substrate 23 is also formed into a sheet, which is then cut to a predetermined width and length to form strips or rods.

For example, when the non-tobacco plant part is a leaf, teas can be preferably used. Not only do different plants produce different types of tea, but even the same plant can produce different types of tea depending on the processing method. Specific examples include Japanese tea, black tea, Angelica leaf tea, sweet tea, Gynostemma 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, sekisho tea, swertia tea, buckwheat tea, taranoki tea, dandelion tea, sweet tea, dokudami tea, eucommia tea, sword bean tea, elderberry tea, nelumbo gracilis tea, pearl barley tea, hub 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 can be used. Using tea leaves allows expensive tea to be reused and put to good use.

Furthermore, extracts of non-tobacco plants such as those listed above, 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.

Examples of aerosol formers as raw materials for 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, and dimethyl tetradecanedione. Among these, glycerin and propylene glycol are preferred.

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.

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

Furthermore, flavor additives that add flavor are preferably used as ingredients of the aerosol-forming substrate 23 as needed. Examples of flavor additives include mint, cocoa, coffee, black tea extract, and tea extract catechin powder. Preservatives that are used in food are preferred, such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

The aerosol-forming substrate 23 may contain menthol and a water-insoluble cross-linked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble cross-linked 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, but may also be a synthetic product. Also, peppermint, mint, peppermint oil, and other substances containing menthol may be used.

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 containing the flavor additive in the wall of the mouthpiece 40. Alternatively, a capsule containing the flavor additive may be disposed between the mouthpiece 40 and the heated body 20. When the flavor additive is enclosed in a capsule, the smoker can break the capsule by pressing it with his or her finger, and the aromatic components of the flavor additive can be volatilized at the desired timing.

Furthermore, if the flavor additive is, for example, encapsulated in a microcapsule, the encapsulated microcapsule may be provided in the heated body 20. Of course, the microcapsule may also be provided in the support 30.

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.

(Method for producing an aerosol-forming substrate)
The manufacturing method of the aerosol-forming substrate 23 described above will be described in detail below in terms of each step. 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 dried product, a preparation step of pretreating other raw materials and weighing the raw materials, a mixing step of mixing the raw materials to form a composition, and a filler molding step of molding the composition.

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 fruit, stems, bark, roots, etc.) that are used are processed into a specific ground material to make a composition. In this case, 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 the drying process, 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 loss of the necessary 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.

In the preparation process, the raw materials required to produce the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation process and then fed into the mixing process.

In the mixing process, a conventional mixer can be used. For example, a mixing device that mixes the raw materials in a mixing tank while applying shear force with a stirring blade is preferably used.

In the filling forming process, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form a rectangular or rod-shaped aerosol-forming substrate 23. In this embodiment, multiple roll mills are prepared to make thin sheets. The use of multiple roll mills is preferable because it is possible to compress the material by forcing it between the narrow rolls and shear the material due to the difference in roll speed, while kneading and dispersing the material, and then form a sheet of the desired thickness using a doctor blade. It can also be made using a press roller or a press machine.

To obtain a powdered or granular aerosol-forming substrate 23, it is preferable to crush 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 the sieving method described in JIS K 0069:1992. In other words, this average particle diameter is the diameter equivalent to 50% of the mass obtained by accumulating the mass from the larger openings in the test results using multiple sieves. The particle diameter at 50% of the accumulated value in the particle size distribution determined by the laser diffraction/scattering method may also be used as the average particle diameter.

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, or water may be added as necessary.

The thickness of the sheet obtained in the filling molding process is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut to a specified width using a cutter, a rotary cutter using a rotating blade, etc.

Here, when imparting adhesiveness to the surface of the aerosol-forming substrate 23, there are no particular limitations as long as the means is capable of imparting adhesiveness, and it is sufficient to attach the aforementioned binder to at least a portion of the substrate. By imparting adhesiveness, when a strip-shaped or rod-shaped aerosol-forming substrate 23 is combined with a powdery, granular, or pasty aerosol-forming substrate 23, the powdery, 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.

(How to use a smoking cartridge)
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.

The smoking article cartridge 1 according to the first embodiment configured in this manner can provide the following effects:

Because the support 30 is composed of multiple granular materials 31, it is easier to manufacture than conventional resin molded products, and the manufacturing costs of the support 30 can be reduced.

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

In addition, multiple granular materials 31 are arranged between the aerosol-forming substrate 23 and the mouthpiece 40, and the multiple granular materials 31 arranged on the side facing the aerosol-forming substrate 23 are bonded together, so that 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 multiple granular materials 31 arranged on the other end 30b or the outer peripheral surface side may be partially bonded together, or all of the granular materials 31 may be bonded together.

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 is basically the same in structure 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.

Figure 4 is a cross-sectional view of the smoking article cartridge 2 according to the second embodiment. As shown in Figure 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 Figure 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.

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 smoking article cartridge 1 according to the first embodiment. The second granular material 34 is made of a capsule in which a flavor additive is enclosed within the 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 also 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 fragrance components and tea leaves, and may also include tar removal components, aerosol formers, etc.

The shape of the second granular material 34 is not particularly limited, and may be a sphere or polygonal shape, but is preferably a capsule of a similar shape to the first granular material 33. The mixing ratio of the first granular material 33 to 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.

The cartridge 2 for smoking articles according to the second embodiment configured in this manner 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 that constitute 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.

Next, we will explain a modified example of the smoking article cartridge 2 according to the second embodiment.

(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.

When the modified smoking article cartridge 2-1 is inserted into the heated smoking article 70, the heating section 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 section 75. When the heating section 75 generates heat in this state, the capsule of the second granular material 34 is dissolved by the heat of the heating section 75, and the flavor additive inside is released to the outside. In the modified smoking article cartridge 2-1 configured in this way, the heat of the heating section 75 is directly transmitted to the capsule of the second granular material 34, so that the capsule of the second granular material 34 can be dissolved more reliably.

Third Embodiment
Next, a smoking article cartridge according to a third embodiment will be described. The smoking article cartridge 3 according to the third embodiment has basically the same configuration as the smoking article cartridge 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.

Figure 6 is a cross-sectional view of a smoking article cartridge 3 according to the third embodiment. As shown in Figure 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 the 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.

The smoking article cartridge 3 according to the third embodiment configured in this manner can achieve the same effects as the first embodiment described above. In addition, 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, so that the position of the aerosol-forming substrate 23 is prevented from shifting when the smoking article cartridge 3 is inserted into the smoking article 70. In addition, the exterior body 10 is supported by the outer peripheral surface of the cylindrical member 35, so that radial deformation can be prevented when the smoking article cartridge 3 is grasped with the fingers.

The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the gist of the present invention. All technical matters included in the technical ideas described in the claims are the subject of the present invention. The above-described 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.

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 are 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. In addition, the cylindrical member 35 that fills the plurality of granular materials 31 and the packaging member 25 that covers the aerosol-forming substrate 23 do not necessarily have to be separate bodies, and the two may be formed integrally. In addition, 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 the aerosol-forming substrate 23 is wrapped in the exterior body 10, multiple granular materials 31 are dropped into the interior of the exterior body 10, and finally the mouthpiece 40 is inserted into the exterior body 10 to produce a cartridge for a smoking article.
