[0010] Embodiments of the present invention will be described below 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 body 20 and a support member 3 It comprises a heating element 20, a support member 30, and a mouthpiece 40. These are arranged in a line along the central axis C1. And the heated object 20, the support member 30 and the mouse Piece 40 is wrapped and integrated with a sheet-like exterior material 10. 0 is made up of, for example, 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, cartridges for smoking accessories may be formed in dimensions other than these.

[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. Furthermore, both ends of the heated object 20 are not covered by a lid member (for example, paper). 25 is made of paper, for example, but the material is not limited as long as it is a sheet-like component.

[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 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-like material, or it may be a granular material. Also, the aerosol-forming substrate 23 This includes combinations of strip-shaped and granular materials, and combinations of strip-shaped and rod-shaped materials. A combination of a rod-shaped member and a powder-like member, or a combination of a strip-shaped member, a rod-shaped member and a powder-like member. It may also be a configuration consisting of a combination of shaped members. In these cases, less raw material is used for each member. If some parts are different, it is preferable because it will improve the aroma and taste.

[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 member 30 includes a first wall portion 31 and a shaft portion 34. The support member 30 is, for example, made of silicone It consists of a cone, with the first wall portion 31 and the shaft portion 34 being formed integrally. Of course, the two are separate. It may be formed. Note that if the shaft portion 34 is provided separately from the first wall portion 31, the shaft portion For example, the composition of 34 may include a rolled-up paper or a crimped polymer sheet. It is possible.

[0019] The first wall portion 31 is formed in a disc shape. The diameter of the first wall portion 31 is the aerosol forming group The diameter of material 23 is approximately equal to the diameter of material 23. Here, "approximately equal to" means that the diameter of the aerosol-forming substrate 23 is approximately equal to the diameter of material 23. When they are equal, the dimensions include the diameter of the aerosol-forming substrate 23 and the thickness of the packaging member 25, i.e. This concept includes the case where the diameter is equal to the diameter of the heated object 20. The diameter of the first wall portion 31 is The diameter may be smaller than that of the aerosol-forming substrate 23. The first wall portion 31 is aerosol-shaped It is positioned facing the base material 23, and the end face of the first wall portion 31 is on the aerosol-forming base material 23 It is in contact with the end (end face) of the part.

[0020] The shaft portion 34 is formed in a cylindrical shape. The shaft portion 34 is coaxial with the central axis C1 from the first wall portion 31. It extends upward toward the mouthpiece 40. The end 34a of the shaft portion 34 is at the end of the mouthpiece 40. It is in contact with the surface.

[0021] The first wall portion 31 is in contact with the aerosol-forming substrate 23, and the end portion 34a of the shaft portion 34 is a mouthpiece By coming into contact with -40, the axial movement of the aerosol-forming substrate 23 is restricted.

[0022] Figure 2 is a cross-sectional view of the first wall portion 31 shown in Figure 1, taken along line II-II. As shown in Figure 2, the first The wall portion 31 has a plurality (four in this embodiment) through holes (first through holes) 32. The two through holes 32 are arranged at equal intervals (90-degree intervals) along the circumferential direction. These four through holes 32 are for air generated when the aerosol-forming substrate 23 is heated. This constitutes the first channel through which the aerosol flows. The diameter of the through-hole 32 is determined by the diameter of the aerosol flow. It is the perfect size for that purpose.

[0023] Furthermore, the space S1 between the shaft portion 34 and the exterior member 10 is a channel through which aerosols flow. Space S1 functions as an exchange area where aerosols flowing through each through-hole 32 interact, It also functions as a cooling unit for cooling the aerosol. That is, the support member 30 is on the heated object 20 The generated aerosol is guided to the mouthpiece 40. At that time, the aerosol is directed to the shaft 34 and The mouthpiece 40 is cooled and interacted with by the space S1 between it and the outer casing member 10. It is inhaled into the smoker's mouth.

[0024] Here, the thickness of the first wall portion 31 is in the range of approximately 1 / 3 to 1 / 10 of the length of the shaft portion 34. This allows for the exchange and cooling effects of aerosols through space S1. This is because it ensures the strength of the support member 30.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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 After being formed into a T-shape, it is cut to have a predetermined width and length to form strips or rods. It can be done.

[0029] 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.

However, glycerin and propylene glycol are preferred.

[0032] 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. .

[0033] 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 material into the solvent.

[0034] 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.

[0035] 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.

[0036] 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 60 may be arranged in this manner (see Figures 19 and 20). If enclosed in capsule 60, the smoker can press capsule 60 with their finger. The capsules 60 can be destroyed, and the aromatic components of the flavor additive can be volatilized at the desired timing. It becomes possible to do so.

[0037] 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.

[0039] (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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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, a three-roll mill is prepared. Using a three-roll mill allows for narrow Compression caused by being pressed between the rollers and shearing due to the difference in roller speeds result in kneading and mixing. By performing processes such as scattering, it is possible to create a sheet of the desired thickness using a doctor blade. This is preferable. It can also be manufactured using a press roller or press machine.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 or granules are combined. When combined with a shaped aerosol-forming substrate 23, strip-shaped or rod-shaped aerosols are formed. The surface of the substrate 23 can be stably held to the powdery or granular aerosol-forming substrate 23. Cut.

[0048] (How to use smoking accessory cartridges) This section explains how to use the smoking accessory cartridge 1. Figure 3 shows the smoking accessory cartridge 1.

The second wall portion 137 has multiple (six in this embodiment) through holes (second through holes) 13 It has 8. The 6 through holes 138 are spaced equally (60-degree intervals) along the circumferential direction. These six through holes 138 are arranged so that the aerosol-forming substrate 23 is heated This constitutes a second channel through which the aerosol generated by the first channel flows. The diameter of the through-hole 138 is The size is suitable for the flow of aerosols. In this embodiment, through holes Holes 132 and through-hole 138 have the same diameter, but their numbers are different.

[0066] Furthermore, the space S1 between the shaft portion 134 and the exterior member 10 is a channel through which aerosols flow. Similar to the first embodiment, the aerosols that flowed through each through-hole 132 are used as an AC section where they interact. In addition to its function as a cooling unit, it also functions as a cooling unit to cool aerosols.

[0067] According to the second embodiment of the smoking device cartridge 2 configured in this way, the following effects are achieved. It can be effective.

[0068] The support member 130 is composed of a first wall portion 131, a shaft portion 134, and a second wall portion 137. Therefore, the structure of the support member 130 can be simplified compared to conventional methods, and the manufacturing cost of the support member 130 can be reduced. It can reduce the amount of waste.

[0069] Furthermore, the support member 130 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40. Because the axial movement of the aerosol-forming substrate 23 is restricted, the smoking device cartridge 2 When inserting it into the smoking device 70, the position of the aerosol-forming substrate 23 is prevented from shifting. Therefore, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stable, resulting in good aerosol formation. This will occur.

[0070] Furthermore, the outer circumferential surface of the first wall portion 131 and the outer circumferential surface of the second wall portion 137 form the exterior member 1 Because 0 is supported, radial deformation when gripping the smoking device cartridge 2 with your fingers is prevented. It can be done. In addition, by having a support member 130, the cartridge 2 for the smoking device can be attached to the smoking device. This also prevents axial deformation when inserting it into the 70.

[0071] Furthermore, the aerosols that pass through the four through holes 132 are cooled while being exchanged in the space S1. Then, because it is inhaled from the mouthpiece 40 through the six through holes 138, aero The aroma and flavor of the sol are improved. Moreover, the number of through holes 138 in the second wall portion 137 is the same as the first Because there are more than the number of through holes 132 in the wall portion 131, aerosols are inhaled from the mouthpiece 40. The resistance during smoking is reduced, resulting in a more pleasant smoking experience for the smoker.

[0072] Next, a modified example of the smoking device cartridge 2 according to the second embodiment will be described.

It is larger than the sum of the opening areas of holes 132 (see Figure 7). In other words, it is a through hole in the first wall portion 131. The configuration is such that the size of the elongated hole 138-2 in the second wall 137-2 is larger than the size of 132. This modified example 2-2 also produces the same effects and advantages as the second embodiment. It is possible.

In other words, in modified example 2-3, the number of notches is the first The same applies to wall section 131-1 and the second wall section 137-2. These four notches 138-3 This constitutes a second channel through which the aerosol flows. The size of each notch 138-3 is Each notch is larger than 132-1. Even with this modified example 2-3, the same process as in the second embodiment is achieved. It can produce a useful effect.

[0081] (Modification 2-4) Figure 13 is a cross-sectional view of the smoking device cartridge 2 according to modified example 2-4. As shown in Figure 13... In the modified example 2-4, the support member 130 has a first wall portion 131 and a second wall portion 137. It has a third wall portion 135 in between. The third wall portion 135 is formed in a disc shape. The diameter of section 135 is less than or equal to the diameters of the first wall section 131 and the second wall section 137. In modified example 2-4, the space between the first wall portion 131 and the second wall portion 137 is the third wall portion 1 It is separated by 35. Therefore, between the first wall portion 131 and the third wall portion 135 Space S1-1 is formed, and space S1-2 is formed between the second wall portion 137 and the third wall portion 135. It is formed. The axial position of the third wall portion 135 is the same as that of the first wall portion 131 and the second wall portion Anywhere between 137 is fine, but in this modified example 204, the third wall portion 135 is the first wall It is positioned approximately midway between section 131 and the second wall section 137.

[0082] Figure 14 is a cross-sectional view of the third wall portion 135 shown in Figure 13, taken from line XIV to XIV. Thus, the third wall portion 135 has a plurality (for example, five) through holes 136. The holes 136 are arranged at equal intervals (72-degree intervals) along the circumference. The five through holes 136 are formed when the aerosol-forming substrate 23 is heated, generating aerosols This constitutes a third flow path through which the fluid flows. In this modified example, through holes 132 and 136 and through holes Hole 138 has the same diameter, but the number of holes differs. The number of through holes 136 can be arbitrary. stomach.

[0083] According to this modified example 2-4, the same effects and advantages as in the second embodiment can be achieved. Furthermore, because it is equipped with a third wall portion 135, the strength of the support member 130 is improved, and the smoking device This further prevents radial and axial deformation of the ridge 2.

[0084] (Variations 2-5) Figure 15 is a cross-sectional view of the smoking device cartridge 2 in modified example 2-5. As shown in Figure 15 In modified example 2-5, the support member 130 is located between the first wall portion 131 and the second wall portion 137. Two shaft portions 134-1 are provided. With this configuration, the rigidity of the support member 130 is As the temperature rises, when inserting the smoking device cartridge 2 into the smoking device 70, the smoking device cartridge This further prevents deformation of part 2. Note that the number of shafts 134-1 may be three or more.

[0085] (Third embodiment) Next, a cartridge for a smoking device according to the third embodiment will be described. The smoking device cartridge 3 is basically the same as the smoking device cartridge 2 according to the second embodiment. Although the overall structure is the same, the main difference lies in the configuration of the support members. Therefore, the following explanation will focus on this difference. This explanation will focus on key points, and any explanations that overlap with the second embodiment will be omitted.

[0086] Figure 16 is a cross-sectional view of a smoking device cartridge 3 according to a third embodiment of the present invention. Figure 16 As shown, the smoking device cartridge 3 according to the third embodiment includes a heated body 20 and a support part It comprises material 230 and a mouthpiece 40.

[0087] The support member 230 includes a first wall portion 231, a shaft portion 234, and a second wall portion 237. The first wall portion 231 is the same as the first wall portion 131 of the second embodiment, and the shaft portion 234 is the same as the second It is the same as the shaft portion 134 of the embodiment. Therefore, the support member 230 and the second according to the third embodiment The structural difference from the support member 130 according to this embodiment is the diameter of the second wall portion. Specifically In the second embodiment, the diameter of the second wall portion 137 is the same as the diameter of the first wall portion 131. However, in the third embodiment, the diameter of the second wall portion 237 is greater than the diameter of the first wall portion 231. It has a small configuration. Specifically, the diameter of the second wall portion 237 is larger than the diameter of the shaft portion 234. Furthermore, it is approximately 1 / 2 to 2 / 3 of the diameter of the first wall portion 231.

[0088] Figure 17 is a cross-sectional view taken along line XVII-XVII of the second wall portion 237 shown in Figure 16. As shown, the second wall portion 237 has a plurality (six in this embodiment) through holes (second through holes It has 238 through holes. The six through holes 238 are spaced equally apart (60 degrees apart) along the circumferential direction. They are arranged at intervals. These six through holes 238 are located when the aerosol-forming substrate 23 is heated. This constitutes a second channel through which the aerosol generated by this process flows. Also, the second wall portion 23 An annular space S2 is formed between the outer edge of 7 and the exterior member 10, and this space S2 This allows aerosols to pass through.

[0089] According to the third embodiment of the smoking device cartridge 3 configured in this way, the following effects are achieved. It can be effective.

[0090] The support member 230 is composed of a first wall portion 231, a shaft portion 234, and a second wall portion 237. Therefore, the structure of the support member 230 can be simplified compared to conventional methods, and the manufacturing cost of the support member 230 can be reduced. It can reduce the amount of waste.

[0091] Furthermore, the support member 230 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40. Because the axial movement of the aerosol-forming substrate 23 is restricted, the smoking device cartridge 3 When inserting it into the smoking device 70, the position of the aerosol-forming substrate 23 is prevented from shifting. Therefore, the heating of the aerosol-forming substrate 23 by the heating unit 75 is stable, resulting in good aerosol formation. This will occur.

[0092] Furthermore, the aerosols that pass through the four through holes 232 are cooled while being exchanged in the space S1. Then, because it is inhaled from the mouthpiece 40 through the six through holes 238, aero The aroma and taste of the sol are improved. Furthermore, in the third embodiment, the aerosol passes through space S2. It is then guided to the mouthpiece 40. This reduces the aerosol inhalation resistance and improves the inhalation comfort. The ground is in good condition.

[0093] Next, a modified example of the smoking device cartridge 3 according to the third embodiment will be described.

[0094] (Variation 3-1) Figure 18 is a cross-sectional view of the smoking device cartridge 3 according to modified example 3-1. As shown in Figure 18... In addition, the smoking device cartridge 3 according to modified example 3-1 has a first supporting member 230 The diameters of wall section 231 and the second wall section 237 are the same, and both are larger than the diameter of the exterior member 10. It is also a small structure. Therefore, between the outer peripheral edge of the first wall portion 231 and the exterior member 10 The configuration forms a ring-shaped space S3.

[0095] In this configuration, the aerosol flows through spaces S3, S1, and S2 and out of the mouthpiece 40. Although it is inhaled, the suction resistance can be reduced by these spaces S1~S3, so the inhalation heart The ground becomes favorable. Also, since both the first wall section 231 and the second wall section 237 have small diameters. This allows for a reduction in the weight of the support member 230. In this modified example 3-1, the second wall The diameter of section 237 may be the same as or smaller than the diameter of the first wall section 231.

[0096] (Variation 3-2) Figure 19 is a cross-sectional view of the smoking device cartridge 3 according to modified example 3-2. As shown in Figure 19... The smoking device cartridge 3 according to modified example 3-2 consists of a support member 230 and a mouthpiece 4 A space S4 is formed between 0 and the capsule 60, and the capsule 60 is placed in this space S4. The capsule 60 is fixed in position by being sandwiched between the second wall portion 237 and the mouthpiece 40. This capsule 60 alters the aroma and taste of the aerosol. The various flavor additives mentioned above can be used.

[0097] According to this modified example 3-2, the capsule 60 is used to flavor the aerosol. This can improve the aroma and flavor. Also, by crushing the 60 capsules by hand, It can achieve a deep flavor.

[0098] (Modified example 3-3) Figure 20 is a cross-sectional view of the smoking device cartridge 3 according to modified example 3-3. As shown in Figure 20... In addition, the smoking device cartridge 3 according to modified example 3-3 includes a support member 230 and an aerosol forming A space S5 is formed between the substrate 23 and the capsule 60, and the capsule 60 is placed in this space S5. Therefore, the capsule 60 is sandwiched between the first wall portion 231 and the aerosol-forming substrate 23. It is rare and its position is fixed.

[0099] According to this modified example 3-3, similar to modified example 3-2, the capsule 60 is used to aerosol Because flavoring is added, the aroma and taste can be improved. Also, 60 capsules Crushing it by hand can result in a deeper flavor.

[0100] Furthermore, the capsule 60 may also be provided between the first wall portion 231 and the second wall portion 237. In this case, multiple capsules smaller than the capsule 60 in modified example 3-3 are placed in space S1. This is also good. Furthermore, if multiple capsules 60 are provided, the flavor additives in each capsule 60 can be different. Doing so will further enhance the aroma and flavor.

[0101] (Modification 3-4) Figure 21 is a cross-sectional view of the smoking device cartridge 3 according to modified example 3-4. As shown in Figure 21... In modification 3-4, instead of the second wall portion 237 of the support member 230, an annular rim is used. The section 255 and the end portion 134a of the shaft portion 134 extend radially from the end portion 134a and the rim portion 25 It has three spoke sections 250 that connect to 5. The material 230 can be simplified. Moreover, it can have the same function as the second wall section 237. Furthermore, it has the advantage of being lighter compared to the case where the second wall portion 237 is used. Section 255 can be omitted.
