The packaging member 16 can be made of paper or the like. A resin material can be used as the material of the flow changing portion 30 . Examples of the resin material that forms the flow changing portion 30 include polypropylene, polylactic acid, and silicone. However, the flow changing portion 30 may be made of a resin material other than this, or a material other than the resin material such as wood or metal (aluminum, etc.). The directional vector of the aerosol-containing airflow flowing in the heated tobacco cartridge 1 from the filler assembly 10 toward the mouthpiece 14a of the filter member 14 has a component in the central axis direction along the length of the heated tobacco cartridge 1. , a radial vector component that is a component in the radial direction of the heated tobacco cartridge 1 , and a circumferential vector component that is a component in the circumferential direction of the heated tobacco cartridge 1 . As used herein, the term “radial vector component” means a radially resolved component of the directional vector of the aerosol-containing airflow flowing through the heated tobacco cartridge 1 . The radial vector component of airflow can be in both positive and negative directions. For example, if the radial direction vector component of the airflow is defined as the positive direction from the center side to the outer peripheral side of the heated cigarette cartridge 1, the radial direction vector component can also be the negative direction from the outer peripheral side to the central direction. As for the axial vector component, when the direction of flow from the accumulated filler body 10 toward the mouthpiece 14a of the filter member 14 is assumed to be the positive direction, the filler is accumulated from the mouthpiece 14a in a part of the heated cigarette cartridge 1. It can be in the negative direction towards body 10 .

In this embodiment, the heated tobacco cartridge 1 is formed with a diameter of 6.5 mm to 7.5 mm and a length of 40 mm to 80 mm.

For these teas, tea leaves after drinking may be used. Expensive tea can be reused and effectively utilized by using used tea leaves.

Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts and processed products can also be used. The forms of the extract include liquid, starch syrup, powder, granules, solution and the like.

Aerosol formers as raw materials for the filler 20 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, and triethyl citrate. , isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and the like. Among them, glycerin and propylene glycol are preferred.

Microcrystalline cellulose as a raw material of the filler 20 is, for example, obtained by partially depolymerizing α-cellulose obtained from fibrous plant pulp with an acid, and removing the soluble portion from the cellulose. , where appropriate, crystallized insoluble portions.

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

Furthermore, a flavor additive that adds flavor as a raw material of the filling 20 is preferably used as necessary. Examples of flavor additives include mint, cocoa, coffee, black tea extract, catechin powder of tea extract, and the like. As the preservative, those used in foods are preferred, and examples thereof include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate and the like.

Filler 20 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed, and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to those obtained from natural products, and may be synthetic products. Mint, mint, peppermint oil, and others containing menthol may also be used.

The flavor additive is applied to the filter member 14 by, for example, impregnating the walls of the filter member 14 .

(Manufacturing process of filling)
The manufacturing process of the filling 20 includes a drying/pulverizing step of drying/pulverizing a tobacco plant or non-tobacco plant as a main raw material and weighing, etc.; and a filling molding step of molding the composition.

In the drying and pulverizing step, the used parts of tobacco plants or non-tobacco plants (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.), which are the main raw materials, are processed into predetermined pulverized products in order to make compositions. . In this case, it is preferable to adjust the water content to be convenient 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 in this range, it is easy to reach the desired amount of water while avoiding the dissipation of the required flavor component. Furthermore, the drying/pulverizing step can be provided with a sieving step for sieving the pulverized material, and the pulverized material can be adjusted to a desired particle size and fed to the mixing step.

In the preparation process, raw materials necessary for producing the filling 20 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and put into the mixing step.

A normal mixer can be used in the mixing step. For example, it is preferable to use a form in which the raw materials in the mixing tank are mixed with a stirring blade while applying a shearing force.

In the filling forming step, the composition in which various raw materials are mixed is formed into a thin sheet and then cut to form the strip-shaped or rod-shaped filling 20 . In this embodiment, a plurality of roll mills are prepared in order to obtain a thin sheet. When multiple roll mills are used, it is possible to make a sheet of a desired thickness with a doctor blade while performing kneading and dispersion by compression by being pushed between narrow rolls and shearing by roll speed difference. ,preferable. Moreover, it can also be manufactured using a press roller or a press machine.

In order to obtain the powdery or granular filler 20, it is preferable to appropriately pulverize or classify the composition. The average particle size of the powdery or granular filler 20 is preferably, for example, 0.1 to 3.0 mm, more preferably 0.5 mm or less. The average particle size is determined by, for example, the sieving method described in JIS K 0069:1992. In other words, this average particle diameter is the diameter corresponding to 50% of the mass obtained by accumulating the mass from the larger mesh size of the test results with a plurality of sieves. Alternatively, the average particle size may be the particle size at an integrated value of 50% in the particle size distribution determined by the laser diffraction/scattering method.

Other means may be used in the filling molding step, such as molding the composition through an orifice under pressure. In addition, in the filling molding step, if necessary, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be further added, and water etc. may be added. Also good.

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

Here, in the case of imparting adhesiveness to the surface of the filler 20, there is no particular limitation as long as it is a means capable of imparting adhesiveness. By imparting adhesiveness, when the strip-shaped or rod-shaped filler 20 and the powdery, granular or paste-shaped filler 20 are combined, the surface of the strip-shaped or rod-shaped filler 20 can be powdery, granular or pasty. The shaped filling 20 can be stably held.

(Structure of the flow changing section of the first embodiment)
FIG. 5(a) shows a cross-sectional view taken along line AA of FIG. 1, and FIG. 5(b) shows a cross-sectional view taken along line BB of FIG. The support member 12 has four through holes 12a along the circumferential direction. The shape, number, size and position of the through-holes 12a of the support member 12 are not limited to these, and the shape, number, size and position suitable for the embodiment can be set as appropriate. The flow changing portion 30 has a solid conical shape, and is arranged so that the top portion is located on the support member 12 side and the bottom surface is located on the filter member 14 side. In this example, the end portion of the flow changing portion 30 is in contact with the end surface of the support member 12, but the present invention is not limited to this. For example, a hole for receiving the top portion of the flow changing portion 30 may be provided in the end surface of the support member 12 and the flow changing portion 30 may be fitted therein.

As shown in FIG. 1, the flow changing section 30 has an airflow guiding section 32 formed so that the cross-sectional area increases from the packed product 10 side toward the filter member 14 side. Therefore, the flow path from the outlet of the support member 12 on the filter member 14 side to the filter member 14 narrows toward the filter member 14 side at the center. As a result, the flow changing section 30 changes the radial vector component of the airflow containing the aerosol that flows along the longitudinal direction from the packing assembly 10 toward the mouthpiece 14 a of the filter member 14 . Specifically, as indicated by the arrows in the figure, the flow changing section 30 changes the radial direction vector component of the airflow in the direction from the inner peripheral side to the outer peripheral side. The flow changing portion 30 is formed to have a length of 70 mm or less in the longitudinal direction of the heated cigarette cartridge 1 . In this example, it is formed to be 8.0 mm, for example. Of course, the flow changing portion 30 may be formed with other length dimensions. The outer diameter at the position where the flow changing portion 30 contacts the end surface of the filter member 14 is less than 7.5 mm, preferably 3.5 mm to 5.0 mm. By setting the outer diameter to 3.5 mm or more, more airflow can flow to the outer peripheral side of the filter member 14 . Also, if the outer diameter is set to 5.0 mm or less, a sufficient size of the flow path necessary for air flow can be ensured.

Due to the flow changing portion 30, the airflow from the packing assembly 10 side flows into the outer peripheral region of the filter member 14, and flows in the filter member 14 so as to gather toward the mouthpiece 14a side toward the center side. Therefore, since the airflow flows using the entire volume of the filter member 14, it is possible to suppress the concentration of impurities in a part of the region. By leveling the airflow in the filter member 14 in this manner, the fluidity of the airflow can be improved, making it easier to inhale, and the influence of impurities on the movement of the airflow can be reduced. In addition, it is possible to suppress the change in taste due to concentration of impurities in a part of the filter member 14 .

(Structure of the flow changing section of the second embodiment)
FIG. 6 shows an enlarged cross-sectional view of the vicinity of the flow changing portion 60 of the second embodiment. The flow changing portion 60 is disposed between the support member 12 and the filter member 14, and has an airflow guiding portion 61 formed so that the cross-sectional area increases from the packed product 10 side toward the filter member 14 side. is doing. The airflow guiding portion 61 has an uneven portion 62 on the surface that is in contact with the airflow containing the aerosol. The configuration of the flow changing portion 60 of this example is the same as that of the flow changing portion 30 of the first example, except that the surface of the air flow changing portion 61 has an uneven portion 62 . In this example, the uneven portion 62 is formed to protrude from the surface of the airflow guiding portion 61 .

In the filter member 14, a first filter 131, a separation portion 133, and a second filter member 132 are concentrically arranged from the center to the outer peripheral side. In this example, the separating portion 133 is formed integrally by wrapping the outer circumference of the first filter member 131 with a sheet-like member, for example. However, the member is not limited to a sheet-like member, and may be formed in a cylindrical shape and the first filter member may be fitted to the inner peripheral surface of the cylindrical member. The second filter member 132 is formed in a cylindrical shape, and the inner peripheral surface of the second filter member 132 is fitted with the outer peripheral surface of the separating portion 133 to form the filter member 14 . In this example, the cross-sectional area ratio of the first filter member 131 and the second filter member 132 perpendicular to the central axis is 1:9 to 9:1, and in this example, for example, 1:1. Of course, the area ratio of the first filter member 131 and the second filter member 132 may be a ratio other than this.

The support member 12 and the filter member 14 are spaced apart in the longitudinal direction to form a convection space 134 . The convection space portion 134 and the filter member 14 form the flow changing portion 130 .

The second filter member 142 has a higher airflow absorption rate than the first filter member 141. . Support member 12 and filter member 14 are adjacent to each other. The first filter member 141 on the inner peripheral side forms a flow changing portion 140 with an airflow guiding portion 145 formed so that the cross-sectional area increases from the packed product 10 side to the mouthpiece 14a side. As a result, when the airflow from the packing assembly 10 side flows from the support member 12 to the filter member 14, the radial direction vector component is changed by the flow changing portion 140 in the direction from the inner peripheral side to the outer peripheral side. guided by the side. The area ratio of the cross sections perpendicular to the central axis of the first filter member 141 and the second filter member 142 is 1:9 to 9:1, and in this example, it is set to 1:1. Of course, the area ratio of the first filter member 141 and the second filter member 142 may be a ratio other than this. The shape, number, size and position of the through-holes of the support member 12 are not limited to these, and can be appropriately set according to the embodiment.

(Structure of the flow changing section of the eleventh embodiment)
FIG. 15 shows a sectional view of a heated tobacco cartridge 1 having a flow changing portion 150 of an eleventh embodiment. The flow changing section 150 is disposed between the packed material assembly 10 and the filter member 14 and has a first flow path member 151 and a second flow path member 155 that are adjacent along the length direction. The outer diameter of the first channel member 151 and the second channel member 155 is 7.5 mm or less, and the total length of the adjacent first channel member 151 and the second channel member 155 in the longitudinal direction is 70 mm. It is below. In this example, it is formed to be 15.0 mm, for example. Also, the length ratio of the first channel member 151 and the second channel member 155 in the longitudinal direction is 1:9 to 9:1. Of course, the lengths and area ratios of the first channel member 151 and the second channel member 155 may be formed with lengths and ratios other than these.

As shown in FIGS. 16(a) and 17(a), the first flow path member 151 has four first through holes 152 in the circumferential direction through which the air flows through in the longitudinal direction. In this example, the cross section of the first through hole 152 in the cross section perpendicular to the central axis of the first flow path member 151 is substantially rectangular, and the size of each side is set to 3.5 mm or less. A spatial convection space 153 that allows the first through holes 152 to communicate with each other is formed on the end surface of the first flow path member 151 that is adjacent to the second flow path member 155 . In this example, the radial size of the convection space 153 is less than 7.5 mm in diameter, for example, 4.0 mm in diameter.

As shown in FIGS. 16(b) and 17(b), the second flow path member 155 has four second through holes 156 in the circumferential direction through which the air flows through in the longitudinal direction. The second through-hole 156 is arranged at an angular position different from that of the first through-hole 152 in the circumferential direction while the first flow path member 151 and the second flow path member 155 are adjacent to each other. In this example, the cross section of the second through-hole 156 in the cross section perpendicular to the central axis of the second flow path member 155 is substantially rectangular, and the size of each side is set to 3.5 mm or less. A spatial convection space 157 that allows the second through holes 156 to communicate with each other is formed on the end surface of the second flow path member 155 adjacent to the first flow path member 151 . In this example, the radial size of the convection space 157 is less than 7.5 mm in diameter, for example, 4.0 mm in diameter.

By adjoining the first flow path member 151 and the second flow path member 155, the convection spaces 153 and 157 of both members are continuous, and the first through hole 152 and the second through hole 156 are communicated. The total length of the convection space 153 and the convection space 157 is less than 70 mm, for example 3.0 mm. Of course, they may be formed with other lengths and ratios. The airflow from the packing assembly 10 side flows into the first through holes 152 of the first channel member 151 . Since the first through-hole 152 is located on the outer peripheral side of the flow changing portion 150 , the airflow from the first through-hole 152 flows toward the inner peripheral side in the convection spaces 153 and 157 . The airflow that has flowed into the convection spaces 153 and 157 flows into the second through hole 156 . Since the second through-hole 156 is located on the outer peripheral side of the flow changing portion 150, the airflow flowing from the convection spaces 153 and 157 to the second through-hole 156 flows toward the outer peripheral side. In this manner, the flow changing section 150 can change the radial direction vector component of the airflow in the convection space sections 153 and 157 to allow the airflow to flow into the outer peripheral portion of the filter member 14 .

Note that the number, shape, size and position of the first through holes 152 and the second through holes 156 in the circumferential direction, the angle formed by the first through holes 152 and the second through holes 156 in the circumferential direction, etc. are limited to this example. can be set arbitrarily.

Also, the convection space portion 157 of the second flow path member 155 forms a recess 158 in the central portion of the second flow path member 155 . The airflow that has flowed into the convection space 157 collides with the wall surface 158 a of the recess 158 . This makes it possible to cause some of the impurities in the airflow to adhere to the wall surface 158 a and reduce the amount of impurities reaching the filter member 14 .

As shown in FIG. 18, a concave portion 154 may be provided on the end surface of the first flow path member 151 on the packed product 10 side. This allows some of the impurities contained in the airflow from the filler assembly 10 to adhere to the recesses 154 .

(Structure of the flow changing section of the 12th embodiment)
Next, the flow changing section 160 of the twelfth embodiment will be described. FIG. 19 shows a sectional view of a heated tobacco cartridge 1 having a flow changing portion 160 of a twelfth embodiment. 20 shows a front view of the flow changing section 160. As shown in FIG. The flow change portion 160 is adjacent to the support member 12 and the filter member 14 at both ends. The shape, number, size and position of the through-holes of the support member 12 are not limited to these, and can be appropriately set according to the embodiment. A plurality of through-holes 161 passing through the flow changing portion 160 in the lengthwise direction are provided in the circumferential direction on the outer peripheral side. A conical concave portion 162 is formed at the end portion of the flow changing portion 160 on the support member 12 side. The airflow from the filler assembly 10 side flows from the inner peripheral side to the outer peripheral side toward the through hole 161 located on the outer peripheral side in the recess 162 . In addition, part of the airflow goes to the deepest part of the recessed portion 162 , and part of the impurities adhere to the recessed portion 162 . As a result, impurities reaching the filter member 14 can be reduced. In FIG. 19, the recess 162 is formed so that the cross-sectional area decreases from the filler assembly 10 side toward the filter member 14 side. Any suitable shape can be used as appropriate. For example, the recess may have a square cross-section or an arcuate cross-section. Also, the position and quantity of the recesses are not limited, and arbitrary positions and quantities can be used as appropriate. Further, the shape, number, size and position of the through-holes 161 provided in the flow changing portion 160 are not limited to these, and can be appropriately set according to the embodiment.

(Structure of the flow changing section of the thirteenth embodiment)
FIG. 21 shows a sectional view of a heated tobacco cartridge 1 having a flow changing portion 170 of a thirteenth embodiment. Also, FIG. 22 shows a cross-sectional view taken along the line AA of FIG. The flow changing part 170 is arranged between the packed material assembly 10 and the filter member 14 and is formed by stacking a large number of columnar members 171 . Spaces 174 are formed between the cylindrical members 171 adjacent to each other and between the cylindrical members 171 and the packaging member 16 , and serve as flow paths for the airflow from the packing assembly 10 . The cylindrical member 171 is formed to have a length of 70 mm or less in the longitudinal direction of the heated cigarette cartridge 1 . In this example, it is formed to be 8.0 mm, for example. Of course, the cylindrical member 171 may be formed with other length dimensions. The outer diameter of the cylindrical member 171 is less than 3.5 mm. If the outer diameter is set to less than 3.5 mm, a large number of cylindrical members 171 can be accumulated, and the gaps 174 can be distributed from the center to the outer circumference.

As shown in FIG. 23, a wall portion 172, which is an end face of the columnar member 171 on the side of the aggregated filler 10, is adjacent to the aggregated filler 10, and the airflow from the aggregated filler 10 flows along the length direction. prevent you from proceeding. Therefore, the airflow enters the gap 174 while changing its radial vector component. In this way, since more airflow can flow from the flow changing portion 170 to the outer peripheral side of the filter member 14, the radial direction vector component of the airflow can change in the direction from the inner peripheral side to the outer peripheral side.

The cylindrical member 171 can be made of a resin material such as polypropylene or polylactic acid, or a metal material such as aluminum. The airflow from the packing assembly 10 is gradually cooled by coming into contact with the surface of the cylindrical member 171 as it flows toward the filter member 14 side. Also, some of the impurities contained in the airflow adhere to the cylindrical member 171 . As a result, the temperature of the airflow in the filter member 14 can be lowered, and impurities reaching the filter member 14 can be reduced.

(Structure of flow changing section of 14th embodiment)
FIG. 24 shows a sectional view of a heated cigarette cartridge 1 having a flow changing portion 180 of a fourteenth embodiment. Also, FIG. 25 shows a cross-sectional view taken along the line AA of FIG. The flow changing portion 180 is arranged in the same manner as the flow changing portion 170 of the thirteenth embodiment, and is formed by stacking many cylindrical members 181 . The cylindrical member 181 has a hollow portion 183 and serves as an air flow passage. In addition, gaps 184 formed between the cylindrical members 181 adjacent to each other and between the cylindrical member 181 and the packaging member 16 also serve as flow paths for the airflow. In this example, the configuration except that the cylindrical member 181 has a hollow portion 183 is the same as the thirteenth example.

As shown in FIG. 26, in this example as well, a wall portion 182, which is the end face of the packing assembly 10 side of the cylindrical member 181, prevents the airflow from flowing in the longitudinal direction, and the airflow has a radial vector component. While changing, it enters the gap 184 and the hollow portion 183 . In this way, since more airflow can flow from the flow changing portion 180 to the outer peripheral side of the filter member 14, the radial direction vector component of the airflow can change in the direction from the inner peripheral side to the outer peripheral side.

The cylindrical member 181 can be made of a resin material such as polypropylene or polylactic acid, or a metal material such as aluminum. The airflow from the packing assembly 10 is gradually cooled by flowing in contact with the outer peripheral surface and the inner peripheral surface of the cylindrical member 181 . Some of the impurities contained in the airflow also adhere to the inner and outer peripheral surfaces of the cylindrical member 181 . As a result, the temperature of the airflow in the filter member 14 can be lowered, and impurities reaching the filter member 14 can be reduced.
