The heating element 20, the support member 30, and the mouthpiece 40 are arranged side by side on the central axis C1. Then, the heating element 20, the support member 30, and the mouse piece 40 are wound and integrated by a sheet-like outer member 10. The outer member 1 0 is made of, for example, paper.

[0012] Here, the cartridge 1 for a smoking device shown in FIG. 1 has, for example, a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. The heating element 20 has a length of 10 to 25 mm Of course, the cartridge for a smoking device may be formed in other dimensions.

[0013] The heating element 20 is formed in a cylindrical shape by winding an aerosol-forming substrate 23, which is a filler, with a sheet-like packaging member 25, and the aerosol-forming substrate 23 is exposed at both ends thereof. That is, both ends of the heating element 20 are not covered by a lid member (for example, paper). The packaging member 25 is made of, for example, paper, but the material is not limited as long as it is a sheet-like member.

[0014] The aerosol-forming substrate 23 is composed of a smoking material made from a tobacco plant or a non-tobacco plant as a raw material, which will be described in detail later. The aerosol-forming substrate 23 is composed of, for example, bundling strip-shaped members and is arranged such that its longitudinal direction is along the central axis C1.

In these cases, it is preferable that at least a part of the raw materials of each member is different, as the aroma and taste will be improved. The mouthpiece 40 is a part that constitutes the suction port of the smoking implement cartridge 1 and is formed using, for example, paper

[0017] etc. Also, the mouthpiece 40 may include a cellulose acetate filter or the like that removes fine particles. A part of the fine particles in the water vapor or aerosol generated by the heated body 20 is filtered by the filter of this mouthpiece 40. The support member 30 includes a first wall portion 31 and a shaft portion 34. The support member 30 is composed of, for example, silica cone, and the first wall portion 31 and the shaft portion 34 are integrally formed. Of course, the two may be formed separately

[0018] If the shaft portion 34 is provided separately from the first wall portion 31, the shaft portion is preferably made of a material having a higher heat resistance than the first wall portion 31. formed. When the shaft portion 34 is provided separately from the first wall portion 31, the shaft portion As the configuration of 34, for example, a rolled paper or a crumpled polymer sheet can be used. It can be used.

[0019] The first wall portion 31 is formed in a disk shape. The diameter of the first wall portion 31 is substantially equal to the diameter of the aerosol forming substrate 23. Here, "substantially equal" means the case where it is equal to the diameter of the aerosol forming substrate 23, and the dimension including the thickness of the packaging member 25 in the diameter of the aerosol forming substrate 23, that is, it includes the case where it is equal to the diameter of the heated body 20. Note that the diameter of the first wall portion 31 may be smaller than the diameter of the aerosol forming substrate 23. The first wall portion 31 is disposed at a position facing the aerosol forming substrate 23, and the end face of the first wall portion 31 is in contact with the end portion (end face) of the aerosol forming substrate 23. including the case where it is equal to the diameter of the aerosol forming substrate 23, and the dimension including the thickness of the packaging member 25 in the diameter of the aerosol forming substrate 23, that is, it includes the case where it is equal to the diameter of the heated body 20. Note that the diameter of the first wall portion 31 may be smaller than the diameter of the aerosol forming substrate 23. The first wall portion 31 is disposed at a position facing the aerosol forming substrate 23, and the end face of the first wall portion 31 is in contact with the end portion (end face) of the aerosol forming substrate 23. it may be smaller than the diameter of the aerosol forming substrate 23. The first wall portion 31 is disposed at a position facing the aerosol forming substrate 23, and the end face of the first wall portion 31 is in contact with the end portion (end face) of the aerosol forming substrate 23. The first wall portion 31 is disposed at a position facing the aerosol forming substrate 23, and the end face of the first wall portion 31 is in contact with the end portion (end face) of the aerosol forming substrate 23. It is in contact with the end portion (end face) of the aerosol forming substrate 23.

[0020] The shaft portion 34 is formed in a columnar shape. The shaft portion 34 extends coaxially with the central axis C1 from the first wall portion 31 toward the mouthpiece 40. The end portion 34a of the shaft portion 34 is in contact with the end face of the mouthpiece 40. The shaft portion 34 extends coaxially with the central axis C1 from the first wall portion 31 toward the mouthpiece 40. The end portion 34a of the shaft portion 34 is in contact with the end face of the mouthpiece 40. It is in contact with the end face of the mouthpiece 40.

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

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

[0023] Also, the space S1 between the shaft portion 34 and the outer member 10 is a flow path through which the aerosol flows. The space S1 functions as an alternating portion where the aerosol flowing through each through-hole 32 alternates, and also functions as a cooling portion for cooling the aerosol. That is, the support member 30 guides the aerosol generated by the heated body 20 to the mouthpiece 40. At this time, the aerosol is alternated and cooled by the space S1 between the shaft portion 34 and the outer member 10, and is sucked into the smoker's mouth through the mouthpiece 40. Here, the thickness of the first wall portion 31 can be in the range of about 1 / 3 to 1 / 10 of the length of the shaft portion 34. By doing so, while having the effects of alternating and cooling the aerosol by the space S1, the strength of the support member 30 can be ensured. Next, specific examples of the 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 following raw materials. The aerosol-forming substrate 23 uses tobacco plants or non-tobacco plants as raw materials. 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 (bulbous roots, tuberous roots, etc.), stems, tubers, skins (stem skins, tree barks, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches, etc.

[0024]

[0025]

[0026]

[0027] ​​​​​​​​​​​ In this specification, the term "plants" refers to a group of plants, such as grasses and trees, in contrast to animals. In addition to organisms that have roots and live in fixed locations, there are also organisms such as microalgae and seaweed. This also includes algae, mushrooms, and other fungi.

[0028] The aerosol-forming substrate 23 is, for example, a dried and ground non-tobacco plant. Aerosol formers, microcrystalline cellulose, flavor additives, preservatives, The mixture is mixed with an adhesive or thickener, crushed or classified into powder or granules, or coated with a sheet. After forming the material into a ball shape, it is cut into strips or rods having a specified width and length. can be.

[0029] For example, when the non-tobacco plant part is a leaf, tea can be preferably used. Not only are the plants that produce tea different, but even the same plants can produce different teas depending on how they are processed. Specifically, for example, Japanese tea, black tea, angelica tea, sweet tea, gynostemma tea, aloe tea, Ginkgo leaf tea, oolong tea, turmeric tea, salicylate tea, Eleuthero tea, plantain tea, Kiodoshi tea, persimmon leaf tea, chamomile tea, chamomile tea, Kawara Kemei 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, saffron tea, shiitake tea, shiso tea, jasmine tea, Ginger tea, horsetail tea, Japanese parsley tea, Swertia japonica tea, Buckwheat tea, Aralia aralia tea, Dandelion tea, Sweet tea Tea, Houttuynia tea, Eucommia tea, Sword bean tea, Elderberry tea, Ragweed 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 These include eucalyptus tea, monk fruit tea, rooibos tea, and bitter melon tea. Alternatively, the tea leaves after drinking may be used. By using tea leaves or the like, expensive tea or the like can be reused and effectively utilized.

[0030] Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts or processed products can also be used. Examples of the form of the extract include liquid, water candy-like, powder, granule, solution, etc.

[0031] The aerosol former as a raw material of the aerosol forming base material 23 is glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and the like. Among them however, glycerin and propylene glycol are preferred.

[0032] The microcrystalline cellulose as a raw material of the aerosol forming base material 23 is, for example, obtained by partially depolymerizing α-cellulose obtained from the pulp of fibrous plants with an acid, and is obtained by removing the soluble part from cellulose and appropriately crystallizing the insoluble part. .

[0033] The microcrystalline cellulose may remain in powder form or may be dispersed in a solvent such as water to form a suspension. In this case, for dispersion in the solvent, a high-speed stirrer, a high-pressure homogenizer, or the like can be used.

[0034] Furthermore, a flavor additive for adding flavor as a raw material of the aerosol forming base material 23 is preferably used as needed. Examples of the flavor additive include perilla, cocoa, coffee, tea extract, Examples include powders of catechins in tea extracts. As preservatives, those used in foods are preferred. Examples include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc.

[0035] The aerosol-forming substrate 23 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpyrrolidone). Combining menthol with a water-insoluble crosslinked polymer can effectively suppress the sublimation of menthol and maintain the flavor of menthol for a long time. Here, menthol is not limited to those obtained from natural products and may be a synthetic product. Also, peppermint, mint, peppermint oil, and other substances containing menthol may be used.

[0036] The flavor additive is provided in the mouthpiece 40, for example, by impregnating the wall of the mouthpiece 40. The mode in which the flavor additive is provided in the mouthpiece 40 is not limited to such a mode. For example, a capsule containing the flavor additive may be embedded in the wall of the mouthpiece 40 so that the flavor additive is provided in the mouthpiece 40. Or, a capsule 60 containing the flavor additive may be arranged between the mouthpiece 40 and the heated body 20 (see FIGS. 19 and 20). When the flavor additive is enclosed in the capsule 60, the smoker can break the capsule 60 by pressing it with a finger and volatilize the aromatic components of the flavor additive at a desired timing.

[0037] Furthermore, when the flavor additive is enclosed in microcapsules, for example, ​​​​​​​​​​​​​​The microcapsules present may be provided on the object to be heated 20.

[0038] Examples of the binder or thickener as the raw material of the aerosol-forming substrate 23 include gums such as guar gum, xanthan gum, gum arabic, and locust bean gum, for example, cellulose binders such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose, for example, organic acids such as starch, alginic acid, and polysaccharides such as conjugate base salts of organic acids such as sodium alginate, sodium carboxymethyl cellulose, carrageenan, agar, and pectin, and combinations thereof.

[0039] (Method for producing the aerosol-forming substrate) The method for producing the aerosol-forming substrate 23 described above will be described separately for each step. The production process of the aerosol forming substrate 23 includes a drying and pulverizing step of drying and pulverizing the tobacco plant or non-tobacco plant as the main raw material, weighing, etc., a preparation step of performing pretreatment, weighing, etc. of other raw materials, and a mixing step of mixing the raw materials to form a composition, and a filler forming step of forming the composition.

[0040] In the drying and pulverizing step, in order to use the tobacco plant or non-tobacco plant as the main raw material (for example, leaves, seeds, dried fruits, stems, barks, roots, etc.) as a composition, it is processed into a predetermined pulverized product. At this time, it is preferable to adjust the water content to a convenient amount for absorbing or supporting the aerosol former, water, and other components to be added later. In drying, the temperature is preferably 60°C or higher and 80 °C or lower. By setting it within this range, while avoiding the dissipation of the required flavor components, the desired ​​​​It is easy to reach the desired moisture content. Further, in the drying and pulverizing process, a sieving step of sieving the pulverized material can be provided, and it can be adjusted to a desired particle size and introduced into the mixing step.

[0041] In the preparation step, the raw materials necessary for producing the aerosol-forming substrate 23 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and introduced into the mixing step.

[0042] In the mixing step, an ordinary mixer can be used. For example, a form in which the raw materials in the mixing tank are mixed while applying a shearing force with a stirring blade is preferably used.

[0043] In the filler forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form the aerosol-forming substrate 23 in the shape of a strip or a rod. In this embodiment, in order to form a thin sheet, a three-roll mill is prepared. When using a three-roll mill, by compression due to being pushed into the narrow roll gap and shearing due to the roll speed difference, kneading, dispersion, etc. are performed while it is possible to form a sheet of a desired thickness with a doctor blade, which is preferable. It can also be produced using a press roller or a press machine.

[0044] In addition, to obtain the aerosol-forming substrate 23 in powder or granular form, it is preferable to appropriately pulverize or classify the above composition. The average particle size of the aerosol-forming substrate 23 in powder or granular form is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less. This average particle size is obtained, for example, by the sieving method described in JIS K 0069:1992. That is, this average particle size is determined by a plurality of sieves. ​​​​​​ Regarding the test results, the mass is integrated starting from the larger eye opening, and the diameter corresponding to 50% of that mass is referred to. Also, the particle size at the integrated value of 50 % in the particle size distribution obtained by the laser diffraction / scattering method may be used as the average particle size.

[0045] In the filler forming step, other means such as passing the composition through an orifice under pressure for forming may be used. Also, in the filler forming step, if necessary, flavor additives such as non-tobacco plants, aerosol solformers, binders or thickeners, preservatives may be further added, or water or the like may be added.

[0046] The thickness of the sheet obtained in the filler forming 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 , such as a rotary cutter of the rotary blade type.

[0047] Here, when imparting adhesiveness to the surface of the aerosol forming substrate 23, there is no particular limitation as long as it is a means capable of imparting adhesiveness, but it is sufficient to adhere at least a part of the aforementioned binder . By imparting adhesiveness, when combining the strip-shaped or rod-shaped aerosol forming substrate 23 with the powdery or granular aerosol forming substrate 23, the powdery or granular aerosol forming substrate 23 can be stably held on the surface of the strip-shaped or rod-shaped aerosol forming substrate 23. substrate 23. can be achieved.

[0048] (Method of using a cartridge for a smoking device) The method of using the cartridge 1 for a smoking device will be described. FIG. 3 is a cross-sectional view of the cartridge 1 for a smoking device inserted into the smoking device 70. The cartridge 1 for a smoking device is a heated smoking It is mounted on and used with the smoking device 70. The smoking device 70 has an insertion part 72 for inserting the smoking device cartridge 1. A needle-shaped or blade-shaped heating part 75 is provided in the insertion part 72. When the heating part 75 generates heat with the smoking device cartridge 1 inserted into the insertion part 72, an aerosol is generated from the aerosol-forming substrate 23. In this state, when the smoker holds the mouthpiece 40 and sucks, the aerosol flows through the space S1 and the mouthpiece 40 in sequence and flows into the smoker's mouth.

[0049] According to the smoking device cartridge 1 according to the first embodiment configured as described above, the following effects can be achieved.

[0050] Since the support member 30 is composed of the first wall part 31 and the shaft part 34, the configuration of the support member 30 can be simplified compared with the prior art, and the manufacturing cost of the support member 30 can be reduced.

[0051] Further, since the support member 30 is interposed between the aerosol-forming substrate 23 and the mouthpiece 40 and restricts the axial movement of the aerosol-forming substrate 23, when the smoking device cartridge 1 is inserted 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 part 75 is stabilized, and a good aerosol is generated.

[0052] In addition, since the exterior member 10 is supported by the outer peripheral surface of the first wall part 31, radial deformation when the smoking device cartridge 1 is grasped by hand can be prevented. Further, by providing the support member 30, axial deformation when the smoking device cartridge 1 is inserted into the smoking device 70 can also be prevented.

[0053] ​​​​​​​​​​​ Moreover, the aerosol passing through the four through-holes 32 is cooled while being exchanged by the space S1 so that the aroma and taste of the aerosol are improved.

[0054] Next, a modification of the smoking implement cartridge 1 according to the first embodiment will be described.

[0055] (Modification 1-1) FIG. 4 is a cross-sectional view of the first wall portion 31-1 according to Modification 1-1. Note that FIG. 4 is a cross-sectional view taken at the same position as the line I I-II in FIG. 1. In the first wall portion 31-1 shown in FIG. 4, a plurality (for example, four) of notches (first notches) 32-1 are provided at the outer peripheral edge. These four notches 32-1 are arranged at 90-degree intervals in the circumferential direction and constitute the first flow path through which the aerosol passes. Even with such a configuration, the same operational effects as those of the above-described first embodiment can be obtained. Note that the number of notches 32-1 is not limited. For example, one large notch 32-1 may be provided. Alternatively, the plurality of notches 32-1 may have different sizes from each other.

[0056] (Modification 1-2) FIG. 5 is a cross-sectional view of the first wall portion 31-2 according to Modification 1-2. Note that FIG. 5 is a cross-sectional view taken at the same position as the line I I-II in FIG. 1. In the first wall portion 31-2 shown in FIG. 5, the outer shape as viewed from the axial direction is formed in a regular hexagon. Six flow paths 32-2 are formed between the outer peripheral edge of the first wall portion 31-2 and the outer member 10 wound so as to be in contact with each vertex of the first wall portion 31-2. These six flow paths 32-2 constitute the first flow path through which the aerosol passes. Even with such a configuration, the same operational effects as those of the above-described first embodiment can be obtained. Note that the outer shape of the first wall portion 31-2 may be a polygon other than a regular hexagon.

Note that the diameter of the through hole 138 is , and is of a size suitable for the aerosol to flow through. Here, in the present embodiment, the through hole 132 and the through hole 138 have the same diameter, but the number of both is different.

[0066] Also, the space S1 between the shaft portion 134 and the outer member 10 is a flow path through which the aerosol flows , and, similar to the first embodiment, functions as an alternating portion where the aerosol flowing through each through hole 132 alternates and also functions as a cooling portion for cooling the aerosol.

[0067] According to the smoking implement cartridge 2 according to the second embodiment configured as described above, the following effects can be achieved.

[0068] Since the support member 130 is composed of the first wall portion 131, the shaft portion 134, and the second wall portion 137 , the configuration of the support member 130 can be simplified compared to the conventional one, and the manufacturing cost of the support member 130 can be reduced.

[0069] Also, since the support member 130 is interposed between the aerosol forming substrate 23 and the mouthpiece 40 and restricts the axial movement of the aerosol forming substrate 23, when the smoking implement cartridge 2 is inserted into the smoking implement 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 portion 75 is stabilized, and a good aerosol is generated.

[0070] Also, since the outer member 1 0 is supported by the outer peripheral surface of the first wall portion 131 and the outer peripheral surface of the second wall portion 137, radial deformation when gripping the smoking implement cartridge 2 with fingers is prevented Furthermore, by providing the support member 130, the cartridge 2 for the smoking article can be It is also possible to prevent deformation in the axial direction when inserting into 70.

[0071] In addition, the aerosol that has passed through the four through holes 132 is cooled while being exchanged by the space S1. Then, the air is inhaled from the mouthpiece 40 through the six through holes 138. The aroma and taste of the sol are improved. Moreover, the number of through holes 138 in the second wall portion 137 is Since the number of the through holes 132 in the wall portion 131 is larger than that of the through holes 132 in the wall portion 131, the aerosol can be inhaled from the mouthpiece 40. This reduces resistance when smoking, resulting in a more comfortable smoking experience for the smoker.
