[0038] The microcrystalline cellulose used as the raw material for the filler 20 is, for example, a material obtained from the pulp of a fibrous plant. It is obtained by partially depolymerizing α-cellulose with acid. The soluble portion is removed from the base and, if necessary, the insoluble portion is crystallized.

[0039] 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, a high-speed stirrer or a high-pressure homogenizer can be used for dispersion in the solvent.

[0040] Furthermore, if necessary, a flavor additive that adds flavor may be preferably used as an ingredient of the filling 20. Flavor additives include mint, cocoa, coffee, black tea extract, and tea extract. As preservatives, those used in food are preferred, e.g. , sorbic acid, potassium sorbate, benzoic acid, sodium benzoate, etc.

[0041] The filling 20 contains menthol and a water-insoluble cross-linked polymer (preferably polyvinyl polyimide). lolidone) may be included. Combining menthol with a non-water-soluble cross-linked polymer This effectively prevents menthol from sublimating, allowing the flavor of menthol to be maintained for a long period of time. Here, menthol is not limited to that obtained from natural products, but may be a synthetic product. , peppermint, mint, peppermint oil, and other menthol-containing substances may also be used.

[0042] The flavor additive may be added to the filter element 14 by, for example, impregnating the walls of the filter element 14. The flavor additive is provided in the filter member 14. The present invention is not limited to such an embodiment, and for example, a capsule containing the flavor additive may be attached to a filter portion. The flavor additive is provided in the filter element 14 by being embedded in the wall of the material 14. Alternatively, a flavor additive may be provided between the filter member 14 and the packing material assembly 20. The flavor additive may be encapsulated in a capsule. If the capsule is inserted into a cigarette, the smoker can break it by pressing it with his finger. This makes it possible to volatilize the aromatic components of the flavor additive at a desired timing.

[0043] Additionally, the flavor additive may be encapsulated, e.g., in a microencapsulated form. The microcapsules may be provided in the packing material accumulation 10. may be provided on the support member 12.

[0045] (Filling manufacturing process) The manufacturing process of the filling material 20 involves drying and grinding the main raw material, which is a tobacco plant or a non-tobacco plant. The other raw materials are pre-treated and weighed, and the other raw materials are pre-treated and weighed. The method includes a mixing step of mixing the ingredients to form a composition, and a filling molding step of molding the composition.

[0046] In the drying and grinding process, the main raw material, tobacco plant or non-tobacco plant parts (e.g. In order to make a composition, the following materials (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a specified crushed material. At that time, the aerosol former, water, and other components that are added later are absorbed or supported. It is preferable to adjust the moisture content to a level suitable for drying. By setting the temperature in this range, it is possible to prevent the necessary flavor components from scattering while obtaining the desired flavor. It is easy to achieve the desired moisture content. In addition, the drying and crushing process includes a sieving process to sift the crushed material. It is also possible to provide a powder having a desired particle size and then introduce the powder into the mixing step.

[0047] In the preparation step, the raw materials necessary for producing the filling 20 can be prepared. The microcrystalline cellulose is weighed in the preparation step and then added to the mixing step.

[0048] In the mixing step, a conventional mixer can be used. For example, A mixing mode in which the ingredients are mixed while applying shear force with a stirring blade is preferably used.

[0049] In the filling molding process, the composition in which various raw materials are mixed is formed into a thin sheet and then cut. By cutting, a strip-shaped or rod-shaped filler 20 is formed. In order to make the mixture into a uniform shape, multiple roll mills are used. The material is compressed by being pressed between the rolls and sheared by the difference in roll speed, resulting in kneading, dispersion, etc. While performing the above steps, it is possible to form a sheet of the desired thickness using a doctor blade. It is also possible to prepare the sheet by using a press roller or a press machine.

[0050] To prepare the powder or granular filler 20, the above composition is crushed or pulverized as appropriate. It is preferable to classify the powder or granular filler 20. The average particle size of the powder or granular filler 20 is, for example, It is preferably 0.1 to 3.0 mm, and more preferably 0.5 mm or less. The average particle size is determined, for example, by the sieving method described in JIS K 0069:1992. In other words, this average particle size is calculated based on the results of tests using multiple sieves, The diameter is calculated by multiplying the mass of the larger one by 50%. The particle size at 50% of the cumulative value in the particle size distribution obtained by the laser diffraction / scattering method was taken as the average particle size. You can do that.

[0051] In the filling molding process, the composition is forced through an orifice under pressure to form a shape similar to other processes. In the filling forming step, a non-tobacco plant, an aerobic plant, etc. may be used as necessary. Solformers, binders or thickeners, flavor additives, and preservatives may be further added. Water or the like may be added.

[0052] The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm. The thickness of the obtained sheet is preferably in the range of 0.1 mm to 0.5 mm. The sheet is then cut to a specified width using a rotary cutter or the like.

[0053] Here, when the surface of the filler 20 is to be made sticky, any means capable of making the surface sticky can be used. Although there is no particular limitation, it is sufficient that the above-mentioned binder is attached to at least a part of the surface. By adding the filling material, a strip or rod-shaped filling material 20 and a powder, granular or paste-shaped filling material 2 are mixed. When combined with 0, powder, granules or paper are applied to the surface of the strip or rod-shaped filler 20. The filler 20 in a slab shape can be stably held.

[0075] (Configuration of the flow change portion of the 13th embodiment) FIG. 21 shows a cartridge 1 for a heated tobacco product having a flow change portion 170 according to the thirteenth embodiment. FIG. 22 shows a cross-sectional view of the AA section of FIG. 21. The filter unit 170 is disposed between the packing assembly 10 and the filter member 14 and is made of a number of cylindrical members. The cylindrical members 171 are arranged in a stack. A gap 174 is formed between the material 171 and the packaging member 16, and the packed material from the packing material accumulation 10 is prevented from being mixed in. The cylindrical member 171 is a passage for the airflow. In this example, it is formed to be 8.0 mm. The columnar member 171 may be formed with other length dimensions. If the outer diameter is set to less than 3.5 mm, a large number of cylindrical members 171 can be integrated. The voids 174 can be distributed from the center to the periphery.

[0076] As shown in FIG. 23, a wall portion 172, which is an end face of a cylindrical member 171 on the packing accumulation 10 side, , adjacent to the packing stack 10, and the air flow from the packing stack 10 proceeds along the length direction. Therefore, the airflow passes through the gap 17 while changing its radial vector component. 4. In this way, the flow rate from the flow change portion 170 to the outer circumferential side of the filter member 14 increases. Since the airflow can flow in a large area, the radial vector component of the airflow is directed from the inner circumference to the outer circumference. It can change in the following direction.

[0077] The cylindrical member 171 is made of a resin material such as polypropylene or polylactic acid, or a metal material such as aluminum. As the airflow from the packing accumulation 10 flows toward the filter member 14, The air gradually cools as it comes into contact with the surface of the cylindrical member 171. A part of the air adheres to the cylindrical member 171. As a result, the temperature of the air flow in the filter member 14 This reduces the amount of impurities that reach the filter member 14.

The configuration other than that 81 has a hollow portion 183 is the same as that of the thirteenth embodiment.

[0079] As shown in FIG. 26, in this example, the wall of the cylindrical member 181, which is the end face on the packing accumulation 10 side, The airflow is prevented from flowing in the longitudinal direction by the portion 182, and the airflow changes its radial vector component. The flow changes in the flow region 182 and the flow region 183. Since more airflow can flow toward the outer periphery of the filter member 14 from the filter member 80, the airflow The radial vector component can change in a direction from the inner periphery side to the outer periphery side.

[0080] The cylindrical member 181 is made of a resin material such as polypropylene or polylactic acid, or a metal material such as aluminum. The airflow from the packing accumulation 10 flows toward the outer circumferential surface and the inner circumferential surface of the cylindrical member 181, respectively. As the air flows through the air, it gradually cools. The particles adhere to the inner and outer circumferential surfaces of the cylindrical member 181.
