[Modes for carrying out the invention]

[0022] Embodiments of the present invention will be described below with reference to the drawings and other figures. However, the present invention can be implemented in many different ways, and should not be interpreted as being limited to the embodiments described below. The drawings may be schematic in order to clarify the explanation, but they are merely examples and should not limit the interpretation of the present invention.

[0023] Furthermore, the letters "First," "Second," etc., appended to each element are merely convenient markers used to distinguish each element and have no further meaning unless specifically explained. In the drawings referenced in this embodiment, identical or similar symbols (simply the number xxx followed by A, B, or 1, 2, etc.) are used to indicate the same part or parts with similar functions, and the explanation of their repetition may be omitted. In addition, some parts of the configuration may be omitted from the drawings. Furthermore, if something is recognizable to a person with ordinary skill in the art to which this invention belongs, no further explanation will be given.

[0024] As used herein, the term “tip” means, in the case of a convex or concave portion provided on the circumferential surface of a support member, the highest point protruding from the circumferential surface in the case of a convex portion, and the deepest point located at the deepest position from the circumferential surface toward the center in the case of a concave portion, and the shape of the tip or deep portion is not limited to pointed portions but also includes rounded portions.

[0025] <First Embodiment> A heated tobacco cartridge according to the first embodiment of the present invention will be described in detail with reference to the drawings.

[0026] (1-1. Components of a heated tobacco cartridge) Figure 1 is a cross-sectional view of a heated tobacco cartridge 1 having a tobacco filler aggregate 10 according to this embodiment. As shown in Figure 1, the heated tobacco cartridge 1 includes a tobacco filler aggregate 10, a heated tobacco support member 20 (hereinafter simply referred to as the support member 20), a filter 30 which serves as the mouthpiece, and a sheet-like packaging member 40. In the heated tobacco cartridge 1, the tobacco filler aggregate 10, the support member 20, and the filter 30 are arranged along the longitudinal direction D1 and integrated by being wound with the packaging member 40.

[0027] The tobacco filler aggregate 10 is formed by bundling elongated tobacco fillers 11 along the longitudinal direction D1 and wrapping them in a sheet-like packaging to form a substantially cylindrical shape. In this example, the tobacco fillers 11 are made of a non-tobacco material. However, the tobacco fillers 11 may also be made of tobacco material.

[0028] The tobacco filling 11 is formed by mixing dried and crushed non-tobacco plants with an aerosol former that generates aerosols, microcrystalline cellulose, flavor enhancers, preservatives, adhesives or thickeners, etc., forming it into a sheet, and then cutting it to have a predetermined width and length. The tobacco filling 11 is not limited to a long shape and may have various shapes. For example, it may be formed into a paste or granules.

[0029] When the tobacco filler 11 is constructed in an elongated shape, the cross-section perpendicular to the central axis C is preferably rectangular, and the ratio of the long side to the short side of the cross-section is preferably in the range of 1:1 to 30:1. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, and more preferably in the range of 0.1 mm to 3.0 mm. The length of the short side is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 0.5 mm. Furthermore, it is preferable that the length of the tobacco filler 11 is approximately the same as the length of the tobacco filler aggregate 10. The length of the tobacco filler 11 is preferably in the range of 10 mm to 25 mm, and more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such a tobacco filler 11 is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm.

[0030] The support member 20 suppresses the movement of the tobacco packing aggregate 10 toward the support member 20 and allows the airflow containing aerosols generated in the tobacco packing aggregate 10 to flow toward the filter 30. The support member 20 is provided, for example, in a cylindrical and solid shape, and is positioned between the tobacco packing 11 and the filter 30 such that its axial direction is along the central axis C. The support member 20 is formed, for example, with a length of 3.0 mm to 50 mm or less along the central axis C. The support member 20 may have different dimensions depending on its function and configuration as appropriate. Other configurations of the support member 20 will be described later.

[0031] The filter 30 is formed in a cylindrical shape, for example, with a diameter of 6.5 mm to 7.5 mm and a length of 50 mm or less along the central axis C. The filter 30 is a part that constitutes the mouthpiece of the smoking device cartridge 1. The filter 30 is formed using, for example, paper. Alternatively, the filter 30 may be formed in a cylindrical shape by winding a sheet-like material made of, for example, paper, or it may include a cellulose acetate filter or the like to remove fine particles. The filter 30 has the function of filtering out some of the fine particles in the water vapor and aerosol generated in the tobacco filling aggregate 10.

[0032] The heated tobacco cartridge 1 according to this embodiment is formed to have a diameter of 6.5 to 7.5 mm and a length of 40 to 60 mm. Setting the diameter of the heated tobacco cartridge 1 to the range of 6.5 to 7.5 mm results in a diameter smaller than the insertion hole for inserting the heated tobacco cartridge provided in the heated smoking device, making it easy to insert the heated tobacco cartridge 1 into the heated smoking device. Setting the length of the heated tobacco cartridge 1 to the range of 40 to 60 mm results in a length longer than the insertion hole for receiving the heated tobacco cartridge provided in the heated smoking device, so that even when the heated tobacco cartridge 1 is inserted into the smoking device, the mouthpiece can be exposed from the heated smoking device, ensuring that the necessary length for the smoker to smoke is secured.

[0033] Furthermore, the tobacco filling aggregate 10 has a length of 10 to 25 mm. Setting the length of the tobacco filling aggregate 10 to 10 mm or more ensures the minimum length required to insert the heating element 52. Setting the length of the tobacco filling aggregate 10 to 25 mm or less ensures a length sufficient to distribute the heat from the heating element 52 to every corner of the tobacco filling 11. Note that the heated tobacco cartridge 1 may have different dimensions than those described above, depending on the shape of the heated tobacco device.

[0034] Figure 2 is a cross-sectional view showing the usage configuration of the heated tobacco cartridge 1. The heated tobacco cartridge 1 is used by being attached to the heated tobacco device body 5. The heated tobacco device body 5 has an insertion section 50 into which the heated tobacco cartridge 1 is inserted. The insertion section 50 is provided with a needle-shaped or blade-shaped heating element 52 that is inserted into the tobacco filling 11 of the inserted heated tobacco cartridge 1. The heating element 52 is electrically controlled by a control unit provided inside the heated tobacco device body 5. When the heating element 52 is inserted into the tobacco filling 11, it generates heat, which can generate an aerosol from the tobacco filling 11. In this state, the user can inhale an airflow containing the aerosol by inhaling from the filter 30. In addition, the support member 20 is solid and is provided between the tobacco filling aggregate 10 and the filter, which prevents the tobacco filling aggregate 10 from moving towards the filter 30.

[0035] (1-2. Configuration of the support member 20) The support member 20 will be described in detail below.

[0036] Figure 3 is a perspective view of the support member 20. As shown in Figure 3, the support member 20 has a first end face 21, a second end face 23, and a circumferential surface portion 25. The first end face 21 of the support member 20 abuts against the end face of the tobacco packing aggregate 10. The second end face 23 of the support member 20 abuts against the end face of the filter 30. The support member 20 has a hole 27 (also called a through hole) that extends from the first end face 21 to the second end face 23, and airflow flows through the hole 27. The support member 20 is provided in a cylindrical shape. For example, silicone resin can be used as the material for forming the support member 20. However, the support member 20 is not limited to silicone resin and may be formed from materials other than resin, such as wood or metal (aluminum, etc.), which increases the cooling effect.

[0037] Figure 4(A) is a side view of the support member 20. Figure 4(B) is a front view of the first end face 21 of the support member 20. As shown in Figures 4(A) and 4(B), the support member 20 has the same shape from the first end face 21 to the second end face 23 in a cross-sectional shape when cut by a plane perpendicular to the longitudinal direction D1.

[0038] The support member 20 has a hole 27 that penetrates from the first end face 21 to the second end face 23. The hole 27 functions as a flow path that allows the airflow containing aerosols generated in the tobacco packing aggregate 10 to flow towards the filter 30.

[0039] As shown in Figures 4(A) and 4(B), the holes 27 are arranged so as not to include the central axis C20 of the circumferential surface 25. In this example, the holes 27 have a cylindrical shape. In this embodiment, six holes 27 are provided along the circumferential direction. At this time, the centers P of the holes 27 are arranged at 60° intervals in the circumferential direction with respect to the central axis C20. Therefore, the six holes 27 are arranged at equal intervals in the circumferential direction. Also, the six holes 27 have the same radius.

[0040] The first end face 21 has a void in the portion with the hole 27, and the rest of the face is solid. This solid portion abuts against the end face of the tobacco packing aggregate 10. When the heating element 52 of the heated tobacco body 5 is inserted into the tobacco packing aggregate 10, it receives a force in the longitudinal direction D1, and the solid portion of the abutting support member 20 can support the tobacco packing aggregate 10.

[0041] The support member 20 has a plurality of protrusions 251 on its circumferential surface 25. The protrusions 251 are provided extending along the longitudinal direction D1. In this example, the protrusions 251 are formed to extend along the entire length of the longitudinal direction D1 from the first end face 21 to the second end face 23 of the circumferential surface 25 of the support member 20. In addition, a plurality of protrusions 251 are provided along the entire circumference in the circumferential direction.

[0042] Each of the multiple protrusions 251 has a tip portion 251a. In this example, the tip portion 251a is rounded. In Figure 4(B), the imaginary line VL1 extending from the center C251 of the protrusion 251 toward the tip portion 251a when viewed from the first end face 21 is the same as the imaginary line extending radially D2 from the central axis C20 of the support member 20. The protrusion 251 has two side portions S251, and the two side portions S251 each connect the tip portion 251a to the circumferential surface portion 25. When the support member 20 is viewed from the first end face 21, the angle θ between the imaginary line VL1 and the imaginary line VL2 provided along the side portion S251 corresponding to the tip portion 251a of the protrusion 251 is acute.

[0043] In this embodiment, the provision of a protrusion 251 on the circumferential surface 25 generates a frictional force between the gripping part of the assembly machine and the tip 251a of the protrusion 251 when the gripping part of the assembly machine grips the support member 20. This makes it easier for the gripping part of the assembly machine to grip the support member 20, enabling the stable manufacture of heated tobacco cartridges.

[0044] Figure 5 is a cross-sectional view of the support member 20 in a state where the packaging member 40 is packaging it. As shown in Figure 5, in this embodiment, a gap 26 is provided between the packaging member 40 wrapped around the outer circumference of the support member 20 and the circumferential surface 25 of the support member 20 by providing a protrusion 251. This allows aerogas to flow between the packaging member 40 and the circumferential surface 25. Therefore, the flow path of the aerogas is expanded in addition to the hole 27, and the fluidity of the aerogas can be improved. Furthermore, in this embodiment, since the gap 26 has a shape that widens toward the packaging member 40, the flow path of the aerosol is larger compared to, for example, when the protrusion has a substantially rectangular shape. It can be taken.

[0045] Furthermore, in this embodiment, the protrusions 251 each have the same height in the longitudinal direction D1. In this case, it is preferable that the height of the protrusions 251 is 0.05 mm or more and 1 mm or less. If the height of the protrusions 251 is less than 0.05 mm, it may become difficult to maintain the shape of the protrusions, or aerosols may not be able to flow smoothly. Also, if the height of the protrusions 251 exceeds 1 mm, the size of the gap between the support member 20 and the packaging member 40 increases, and a portion of the tobacco filler 11 may enter the gap, making it difficult to prevent the tobacco filler aggregate 10 from moving towards the filter 30. Furthermore, the above range is desirable from the viewpoint of maintaining the shape of the protrusions.

[0046] Furthermore, in this embodiment, the support member 20 can adjust the fluidity of the aerosol (airflow) from the tobacco filler aggregate 10 by adjusting the void ratio, which is the ratio of the cross-sectional area of ​​the through-hole to the cross-sectional area of ​​the support member 20, along with the void ratio between the circumferential portion 25 and the packaging member 40. Details of the void ratio will be described later.

[0047] When the support member 20 of this embodiment is packaged with the packaging member 40, a plurality of voids 26 are provided between the circumferential surface 25 and the packaging member 40, and these voids can be used as aerosol passages. The voids at the first end face of the support member 20 consist of voids 26 and six holes 27, and the ratio of the void ratios of the voids 26 to the holes 27 is preferably in the range of 1:1 to 1:12. The void ratio of the voids 26 is preferably in the range of 1% to 5% of the area surrounded by the packaging member 40, and the void ratio of the holes 27 is preferably in the range of 1% to 60%. If the voids 26 exceed the upper limit of the above range, when external pressure is applied, the packaging member 40 may collapse, making it impossible to maintain the shape of the cartridge as a whole, or the support function of the support member 20 may not be maintained (for example, the tobacco filler aggregate may easily enter the voids 26 and holes 27). Furthermore, if the void 26 falls below the lower limit of the above range, it may impair the flow of aerosols (for example, the flow path becomes narrower, reducing the amount of aerosol flowing, thus requiring more force to suction).

[0048] In other words, by using this embodiment, when external pressure is applied, the packaging member 40 does not collapse, the solid portion of the support member 20 suppresses the movement of the tobacco filler aggregate 10 toward the support member 20, and because multiple voids 26 are provided between the packaging member 40 and the support member 20, the effect of aerosol circulation can be enhanced by allowing aerosol to flow through the voids 26 in addition to the holes 27.

[0049] In addition, the air permeability resistance may be adjusted by the thickness and material of the packaging member 40 in conjunction with the void ratio. In this embodiment, since a gap 26 is provided between the packaging member 40 and the support member 20, when the filter 30 draws air in and the inside of the packaging member 40 becomes a negative pressure state, outside air is drawn in through the packaging member 40. At this time, the degree to which outside air is drawn in can be changed by the air permeability resistance of the packaging member 40.

[0050] <Second Embodiment> In the first embodiment of the present invention, an example was shown in which a protrusion extends in the longitudinal direction of the circumferential surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member in which the protrusion is provided in a direction inclined with respect to the longitudinal direction will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the explanation as appropriate.

[0051] Figure 6 is a side view of the support member 20A. As shown in Figure 6, the support member 20A has a protrusion 251A on its circumferential surface 25A. The protrusion 251A may extend in a direction intersecting the longitudinal direction D1. Specifically, the protrusion 251A is provided in a direction inclined with respect to the longitudinal direction D1. In this case, the aerosol flow path becomes longer compared to the case where the protrusion 251A extends in the longitudinal direction D1, and the cooling time can be increased. Therefore, by using this embodiment, the gripping part (manufacturing device) of the assembly machine can more easily grip the support member 20A, enabling the stable manufacture of heated tobacco cartridges, and the protrusion 251A is not linear. This allows for a change in the inhalation sensation when aerosols are inhaled, compared to when they are installed in a different location.

[0052] <Third Embodiment> In the first embodiment of the present invention, an example was shown in which a convex portion extends in the longitudinal direction of the circumferential surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member having a curved convex portion will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the explanation as appropriate.

[0053] Figure 7 is a side view of the support member 20B. As shown in Figure 7, on the circumferential surface portion 25B of the support member 20B, the protrusion 251B may have a tip and be arranged in a curved shape from the first end face 21 to the second end face 23. In this case, the aerosol flow path can be made longer compared to the case where the protrusion 251B extends linearly in the longitudinal direction D1. This makes it easier for the manufacturing machine (assembly machine) to grip the cartridge, enabling stable production of heated tobacco cartridges, and also allows for a change in the smoking sensation when the smoker inhales the aerosol compared to the case where the protrusion is provided linearly.

[0054] <Fourth Embodiment> In this embodiment, a support member different from that of the first embodiment will be described. Specifically, a support member in which the protrusions are arranged in a wave-like shape from the first end face to the second end face will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the explanation as appropriate.

[0055] Figure 8(A) is a side view of the support member 20C. Figure 8(B) is a front view of the first end face 21 of the support member 20C. As shown in Figures 8(A) and 8(B), in the support member 20C, the protrusions 251C may be arranged in a wave shape in the longitudinal direction D1 from the first end face 21 to the second end face 23. In this case, the aerosol flow path can be made longer compared to the case where the protrusions 251C extend linearly in the longitudinal direction D1. This also changes the aerosol cooling time. Therefore, by using this embodiment, the gripping part (manufacturing device) of the assembly machine can grip the support member 20C more easily, enabling the stable manufacture of heated tobacco cartridges, and also making it possible to change the smoking sensation when a smoker inhales the aerosol compared to the case where the protrusions 251C are provided linearly.

[0056] <Fifth Embodiment> In this embodiment, a support member different from that of the first embodiment will be described. Specifically, a support member in which a protrusion is provided along the circumferential direction will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the description as appropriate.

[0057] Figure 9(A) is a side view of the support member 20D. Figure 9(B) is a front view of the first end face 21 of the support member 20D. As shown in Figures 9(A) and 9(B), the support member 20D has a first end face 21, a second end face 23, and a circumferential surface portion 25D. The circumferential surface portion 25D of the support member 20D has a protrusion 251D. The protrusion 251D has a tip portion 251Da and may be provided along the circumferential direction. In this case, in Figure 9(A), the imaginary line VL1 extending from the center C251D of the protrusion 251D toward the tip portion 251Da is the same as the imaginary line extending radially D2 from the central axis C20D of the support member 20D. The protrusion 251D has two side portions S251D, each of which connects the tip portion 251Da and the circumferential portion 25D. When the support member 20D is viewed from the circumferential portion 25D side, the angle θ between the imaginary line VL1 and the imaginary line VL2, which is provided along the side portion S251D corresponding to the tip portion 251Da of the protrusion 251D, is acute.

[0058] The number of protrusions 251D is controlled by the longitudinal length of the support member 20D. In this embodiment, the number of protrusions 251D that contact the gripping part of the assembly machine increases compared to the case where the protrusions 251 extend in the longitudinal direction D1. The increase in the number of contacting protrusions 251D makes it easier for a larger frictional force to be generated when the gripping part of the assembly machine and the support member 20D come into contact. Therefore, by using this embodiment, the gripping part (manufacturing device) of the assembly machine can more easily grip the support member 20D, and heated tobacco cartridges can be manufactured stably.

[0059] <Sixth Embodiment> In this embodiment, a support member different from that of the first embodiment will be described. Specifically, a support member in which multiple protrusions are provided intersectingly will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the description as appropriate.

[0060] Figure 10(A) is a side view of the support member 20E. Figure 10(B) is a front view of the first end face 21 of the support member 20E. As shown in Figures 10(A) and 10(B), the support member 20E includes a plurality of protrusions 251E on its circumferential surface 25E. Each protrusion 251E has a protrusion 251E1 and a protrusion 251E2. The protrusion 251E1 has a tip 251E1a and is provided along the longitudinal direction D1. The protrusion 251E2 has a tip 251E2a and is provided along the circumferential direction. The protrusions 251E1 and 251E2 may be provided intersecting each other.

[0061] In this case, the height of the protrusion 251E1 and the height of the protrusion 251E2 may be different. In this example, the height of the protrusion 251E2 is greater than the height of the protrusion 251E1. This increases the number of protrusions 251E2 that come into contact with the gripping part of the assembly machine. The increased number of contacting protrusions makes it easier for a large frictional force to be generated when the gripping part of the assembly machine and the support member 20E come into contact.

[0062] Furthermore, in this embodiment, the intersecting of the convex portion 251E1 and the circumferential convex portion 251E2 forms a grid-like groove 251EV. Aerosols can partially accumulate in the groove 251EV. This diversifies the aerosol flow path and allows for different aerosol cooling times. Therefore, by using this embodiment, the gripping portion (manufacturing device) of the assembly machine can more easily grip the support member 20E, enabling the stable manufacture of heated tobacco cartridges, and also allowing for a change in the smoking sensation when a smoker inhales the aerosol, compared to the case where the convex portions are provided in a straight line.

[0063] <Seventh Embodiment> In the first embodiment of the present invention, an example was shown in which the support member has irregularities along the entire length of the circumferential surface portion 25 in the longitudinal direction D1 and throughout the entire circumferential direction, but the present invention is not limited thereto. In this embodiment, a support member 20 different from that of the first embodiment will be described. A support member 20 in which a protrusion 251 is provided in a part of the circumferential surface portion 25 will be described.

[0064] Figures 11 to 14 are side views of the support member 20F. As shown in Figures 11 to 14, the support member 20F has a protrusion 251F on its circumferential surface 25F. The protrusion 251F may be provided in a portion of the circumferential surface 25F.

[0065] In this case, as shown in Figure 11(A), it may be provided wider in the circumferential direction than in the longitudinal direction D1. Alternatively, as shown in Figure 11(B), it may be provided wider in the longitudinal direction D1 than in the circumferential direction.

[0066] Furthermore, the support member 20F may be provided in multiple regions. For example, as shown in Figure 12(A), if the protrusion 251F is widely provided in the circumferential direction, the protrusion 251F may be provided in multiple regions in the longitudinal direction D1. Also, as shown in Figure 12(B), if the protrusion 251 is widely provided in the longitudinal direction D1, the protrusion 251F may be provided in multiple regions in the circumferential direction.

[0067] Furthermore, as shown in Figure 13(A), the protrusions 251F may be provided on a part of the circumferential surface 25F and extend over the entire circumference of the circumferential surface 25F. In this case, as shown in Figure 13(B), the protrusions 251F may be provided in multiple regions in the longitudinal direction D1.

[0068] Furthermore, as shown in Figure 14(A), the protrusion 251F may be provided on a part of the circumferential surface 25F along its entire length in the longitudinal direction D1. In this case, as shown in Figure 14(B), the protrusion 251F may be provided in multiple regions in the circumferential direction.

[0069] In this embodiment, since a protrusion 251F is provided on the circumferential surface 25F, frictional force is more easily generated when the assembly machine grips the support member 20F. As a result, the gripping part of the assembly machine can more easily grip the support member 20F, enabling the stable manufacture of heated tobacco cartridges.

[0070] <Eighth Embodiment> In the first embodiment of the present invention, an example was shown in which a protrusion 251 extends in the longitudinal direction D1 of the circumferential surface portion 25 of the support member, but the present invention is not limited thereto. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member provided with a protruding protrusion will be described.

[0071] Figure 15(A) is a side view of the support member 20G. Figure 15(B) is a front view of the first end face 21 of the support member 20G. As shown in Figures 15(A) and 15(B), the circumferential surface portion 25G has protrusions 251G. The protrusions 251G have a projection shape. The protrusions 251G are arranged in the longitudinal direction D1 and the circumferential direction. Each protrusion 251G has a tip portion 251Ga. In Figure 15(B), the imaginary line VL1 extending from the center C251G of the protrusion 251 toward the tip portion 251Ga when viewed from the first end face side is the same as the imaginary line extending radially D2 from the central axis C20G of the support member 20G. The protrusion 251G has two side portions S251 The support member 20G has a G, and the two side portions S251G connect the tip portion 251Ga and the circumferential portion 25G, respectively. When the support member 20G is viewed from the first end face 21 side, the angle θ between the imaginary line VL1 and the imaginary line VL2 provided along the side portion S251G corresponding to the tip portion 251Ga of the convex portion 251G is acute.

[0072] In this embodiment, the number of protrusions equals the number of projections, which increases the frictional force between the support member 20G and the gripping part of the assembly machine when manufacturing heated tobacco cartridges. As a result, the gripping part of the assembly machine can more easily grip the support member 20G, enabling stable manufacturing of heated tobacco cartridges.

[0073] In this embodiment, the adjacent protrusions 251G are shown as being arranged in the longitudinal direction D1, but this is not limited to this. For example, other protrusions 251G adjacent to one protrusion 251G may be arranged in a direction intersecting the longitudinal direction D1.

[0074] Figure 16(A) is a side view of the support member 20H. Figure 16(B) is a front view of the first end face 21 of the support member 20H. As shown in Figure 16(A), the protrusions 251H may be arranged in a zigzag pattern oblique to the longitudinal direction D1, for example. In this case, as shown in Figure 16(B), when viewed from the first end face 21 side, adjacent protrusions 251H partially overlap. As a result, the aerosol flow path becomes longer compared to when the aerosol flows linearly. Therefore, the cooling time of the aerosol is diversified. Consequently, it becomes easier for assembly machines to grip the cartridges, enabling stable production of heated tobacco cartridges, and also making it possible to change the smoking sensation when a smoker inhales the aerosol.

[0075] <Ninth Embodiment> In the first embodiment of the present invention, an example was shown in which a convex portion extends in the longitudinal direction of the circumferential surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member having a recess extending in the longitudinal direction on the circumferential surface will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the explanation as appropriate.

[0076] Figure 17(A) is a side view of the support member 20J. Figure 17(B) is a front view of the first end face 21 of the support member 20J. As shown in Figures 17(A) and 17(B), the circumferential portion 25J of the support member 20J has a recess 252. The recess 252 is arranged linearly in the longitudinal direction D1 from the first end face 21 to the second end face 23.

[0077] In Figure 17(B), the recess 252 has two side portions S252, and the two side portions S252J each connect the tip portion 252a and the circumferential portion 25J. At this time, when the support member 20J is viewed from the first end face 21 side, the angle θ between the imaginary line VL1 extending from the center C252 of the recess 252 toward the tip portion 252a as viewed from the first end face 21 side and the imaginary line VL2 provided along the side portion S252 corresponding to the tip portion 252a of the recess 252 is acute.

[0078] In this embodiment, the presence of a recess 252 in the support member 20J makes it easier for the tip of the gripping part of the assembly machine to catch on the support member 20J. As a result, the gripping part of the assembly machine can more easily grip the support member 20J, enabling the stable manufacture of heated tobacco cartridges.

[0079] In this embodiment, the recess 252 is shown as being arranged linearly in the longitudinal direction D1 from the first end face 21 to the second end face 23, but it may also be provided in accordance with the shapes described in the second to seventh embodiments, etc.

[0080] <Tenth Embodiment> In the eighth embodiment of the present invention, an example was shown in which the support member has a protruding projection on its circumferential surface, but the present invention is not limited thereto. In this embodiment, a support member different from that of the eighth embodiment of the present invention will be described. Specifically, an example having a recessed shape will be described.

[0081] Figure 18(A) is a side view of the support member 20K. Figure 18(B) is a front view of the first end face 21 of the support member 20K. As shown in Figures 18(A) and 18(B), the circumferential surface portion 25K has a plurality of recesses 252K. The recesses 252K have a recessed shape with a tip portion 252Ka. The recesses 252K are arranged in the longitudinal direction D1 and the circumferential direction. Each recess 252K has a tip portion 252Ka.

[0082] In this embodiment, the support member 20K has multiple recesses 252K, which makes it easier for the tip of the gripping part of the assembly machine to catch on the recesses 252K of the support member 20K. As a result, the gripping part of the assembly machine can more easily grip the support member 20K, enabling stable production of heated tobacco cartridges.

[0083] Furthermore, in this embodiment, the retention of aerosols within the recess 252K alters the aerosol flow path. This makes it possible to alter the smoking sensation experienced by the smoker when they inhale the aerosols.

[0084] <Embodiment 11> In this embodiment, a support member different from that of the first embodiment will be described. Specifically, a support member having multiple fine protrusions arranged in the circumferential direction will be described. In this embodiment, the same configuration as in the first embodiment will be omitted from the description as appropriate.

[0085] Figure 19(A) is a side view of the support member 20L. Figure 19(B) is a front view of the first end face 21 of the support member 20L and a partially enlarged view. As shown in Figures 19(A) and 19(B), a plurality of fine protrusions 251L may be arranged on the circumferential surface 25L of the support member 20L in the longitudinal direction D1 from the first end face 21 to the second end face 23. The fine protrusions 251L have a pointed tip 251La.

[0086] The support member 20L has six holes 27L (through holes). Of the six through holes, five are evenly spaced, separated by 72 degrees in the circumferential direction. The remaining through hole is located in the center of the first end face 21.

[0087] In this embodiment, 100 to 150 fine protrusions 251L may be arranged in the circumferential direction. The height of the fine protrusions 251L may be 1 / 100 to 1 / 50 of the width (diameter) of the support member. In this example, 137 fine protrusions 251L are arranged in the circumferential direction. In this case, the diameter of the support member is 7 mm, and the height T251L of the protrusions 251L is 0.1 mm. The width W251La (also called pitch) between the tips 251La of adjacent protrusions 251L is 0.16 mm.

[0088] This embodiment increases the contact area (contact points) with the gripping member while maintaining the shape of the protrusion. This increases the frictional force between the gripping part of the assembly machine and the support member. Therefore, it becomes easier to grip the support member with the gripping part of the assembly machine.

[0089] Furthermore, when the support member of this embodiment is packaged with a packaging member, a plurality of voids 26 are provided between the circumferential surface 25L and the packaging member 40, and these voids can be used as aerosol passages. At this time, the voids at the first end face of the support member 20L are the voids 26 and six holes 27L. The ratio of the void ratios of the voids 26 to the holes 27L is preferably in the range of 1:1 to 1:12. The void ratio of the voids 26 is preferably in the range of 2% to 4% of the area surrounded by the packaging member 40, and the void ratio of the holes 27L is preferably in the range of 2% to 48%. If the voids 26 exceed the upper limit of the above range, when external pressure is applied, the packaging member 40 may collapse, making it impossible to maintain the shape of the cartridge as a whole, or the support function of the support member 20 may not be maintained (for example, the tobacco filling 11 of the tobacco filling aggregate 10 may easily enter the voids 26 and holes 27). Furthermore, if the void 26 falls below the lower limit of the above range, it may impair the flow of aerosols (for example, the flow path becomes narrower, reducing the amount of aerosol flowing, thus requiring more force for suction). In this embodiment, the void ratio of the hole 27 is 30%, and the void ratio of the void 26 is 3%.

[0090] In other words, by using this embodiment, the solid portion of the support member 20L suppresses the movement of the tobacco filler aggregate 10 toward the filter 30, and by providing multiple voids 26 between it and the packaging member 40, the aerosol can flow not only through the holes 27L but also through the voids 26, thereby enhancing the effect of aerosol circulation.

[0091] (modified version) Within the scope of the concept of the present invention, a person skilled in the art can conceive of various modifications and alterations, and it is understood that such modifications and alterations also fall within the scope of the present invention. For example, any addition, deletion, or design change of components, or addition, omission, or modification of processing conditions, made by a person skilled in the art to the above-described embodiments, are also included within the scope of the present invention, as long as they retain the gist of the present invention. Furthermore, the configurations of each embodiment may be used in appropriate combinations.

[0092] In the first embodiment of the present invention, an example was shown in which a heated tobacco cartridge 1 is provided with a tobacco filler aggregate 10, a support member 20, and a filter 30 that serves as the mouthpiece. However, the present invention is not limited thereto. Another member, such as a cooling member or a heat insulating member, may be provided between the support member 20 and the filter 30. Furthermore, a cavity may be provided between the support member and the filter to improve airflow. In this case, the cavity may be provided in a range of 1 mm to 20 mm. This results in a wider cavity, which can improve the amount of aerosol inhaled from the heated aroma generator. The cavity is also an exchange space. It also functions as a filter, resulting in superior flavor. Furthermore, even if manufacturing errors cause the tea leaves or filter to be slightly longer than intended, the presence of this cavity allows it to absorb these manufacturing defects.

[0093] Alternatively, the heated tobacco cartridge 1 may consist only of a tobacco filler aggregate 10 and a support member 20. In this case, the heated tobacco cartridge 1 does not need to have a filter.

[0094] In the first embodiment of the present invention, an example was shown in which the holes 27 (through holes) have the same radius and are circular in shape, but the invention is not limited thereto. The holes 27 may each have different radii. The holes 27 may also be elliptical or rectangular in shape.

[0095] In the first embodiment of the present invention, an example is shown in which the support member 20 has a hole, but the invention is not limited thereto. Depending on the shape of the protrusion 251, the hole 27 may not be provided.

[0096] In the first embodiment of the present invention, an example in which multiple protrusions or recesses are provided is shown, but the invention is not limited thereto. The problem of the present invention can be solved by providing at least one protrusion or recess.

[0097] In the first embodiment of the present invention, an example was shown in which the protrusions 251 each have the same height, but the present invention is not limited to this. The protrusions 251 may each have different heights. Also, if the protrusions 251 extend in the longitudinal direction D1, the heights of the protrusions 251 may differ in the longitudinal direction D1. Also, if the protrusions 251 extend along the circumferential direction, the heights of the protrusions 251 may differ in the circumferential direction. Furthermore, the heights of adjacent protrusions 251 may differ. This diversifies the aerosol flow path. Therefore, it is possible to change the smoking sensation of the aerosol obtained in the heated tobacco cartridge.

[0098] In the first embodiment of the present invention, an example was shown in which the imaginary line VL1 extending from the center of the protrusion 251 toward the tip portion 251a when viewed from the first end face side is the same as the imaginary line extending radially D2 from the central axis C20 of the support member 20, but the invention is not limited to this. Figure 20 is a front view of the first end face 21 of the support member 20M. As shown in Figure 20, the circumferential surface portion 25M of the support member 20M has a protrusion 251M. The imaginary line VL1 extending from the center C251M of the protrusion 251M toward the tip portion 251Ma may be different from the imaginary line VL3 extending radially from the central axis C20M of the support member 20M. In this case, it is desirable that the angle between the two imaginary lines VL1 and VL3 is less than 5 degrees. This makes it possible to have the same effect as when the center and tip portion 251a of the protrusion 251 are located on the same imaginary line in the first embodiment.

[0099] Furthermore, while the fourth embodiment of the present invention shows an example in which the protrusions 251C are arranged with a wave shape in the longitudinal direction D1, the invention is not limited to this. The protrusions 251N of the support member 20N may be arranged in the circumferential direction or obliquely to the longitudinal direction D1. Figure 21 is a side view of the support member 20N. For example, as shown in Figure 21, the protrusions 251N may be arranged with a wave shape in directions intersecting the longitudinal direction D1.

[0100] Furthermore, in the sixth embodiment of the present invention, an example was shown in which the multiple protrusions 251 are arranged to intersect in the longitudinal direction D1 and the circumferential direction, but the present invention is not limited thereto. For example, some of the multiple protrusions 251E may extend in a direction inclined with respect to the longitudinal direction D1 or the circumferential direction. The protrusions 251E may intersect in the longitudinal direction D1 and the circumferential direction and may also have a wave shape. This diversifies the aerosol flow path and makes it possible to change the smoking sensation when a smoker inhales the aerosol.

[0101] Furthermore, while the embodiments of the present invention show examples in which recesses or protrusions are provided with a certain regularity, the invention is not limited thereto. Figure 22 is a side view of the support member 20P. As shown in Figure 22, the support member 20P has protrusions 251P on its circumferential surface 25P. The protrusions 251P may be provided irregularly. In this case, the provision of protrusions 251P generates frictional force between the gripping part of the assembly machine and the protrusions, and also diversifies the aerosol flow path, making it possible to change the smoking sensation when a smoker inhales the aerosol. Therefore, the assembly machine can grip the cartridge more easily, enabling stable production of heated tobacco cartridges, and allowing for variations in the smoking sensation of the aerosol.

[0102] Furthermore, although an example having a tip portion is shown in one embodiment of the present invention, the invention is not limited thereto. Figure 23 is a cross-sectional view of the support member 20Q and an enlarged view of the protrusion 251Q. As shown in Figure 23, the upper part 251Qu of the protrusion 251Q on the circumferential surface portion 25Q of the support member 20Q may be flat. In this case, when viewing the support member 20 from the first end face 21 side, it is desirable that the width W251Qu of the upper part 251Qu of the protrusion 251Q is one-fifth or less of the width W251Qd of the lower part 251Qd of the protrusion 251. This makes it possible to achieve the same effect as when the protrusion has a tip portion (top).

[0103] Furthermore, while the first embodiment of the present invention shows an example in which one protrusion has a tip portion with a single apex, the invention is not limited thereto. Figure 24 is a cross-sectional view of the support member 20R and an enlarged view of the protrusion 251R. As shown in Figure 24, the support member 20R has a protrusion 251R on its circumferential surface portion 25R. The protrusion 251R may have a tip portion 251Ra with multiple apex portions. In this case, the angle between the imaginary line VL1R connecting the center C251R of the protrusion and one apex 251Ra1 on the tip portion 251Ra and the imaginary line VL2R provided along the side portion S251R corresponding to the apex 251Ra1 is acute. This ensures contact with the member being gripped. The contact area (contact points) increases. Therefore, the frictional force between the gripping part of the assembly machine and the support member can be increased. Consequently, the gripping part of the assembly machine can grip the support member more easily.

[0104] Furthermore, although the first embodiment of the present invention described an example in which the convex portion has two sides when the first end face 21 is considered the front, the present invention is not limited thereto. The convex portion may have an arc.

[0105] Figure 25(A) is a side view of the support member 20S. Figure 25(B) is a front view of the first end face 21 of the support member 20S. As shown in Figures 25(A) and 25(B), the support member 20S has protrusions 251S on the circumferential surface 25S. The protrusions 251S are arranged in the longitudinal direction D1 and the circumferential direction. Each protrusion 251S has a tip portion 251Sa. In Figure 25(B), the imaginary line VL1 extending from the center C251S of the protrusion 251S toward the tip portion 251Sa when viewed from the first end face side is the same as the imaginary line extending radially D2 from the central axis C20S of the support member 20. The protrusion 251S includes an arc S251S and connects the tip portion 251Sa and the circumferential surface 25S.

[0106] In this embodiment, the provision of a protrusion 251S on the circumferential surface 25S generates a frictional force between the gripping part of the assembly machine and the tip 21Sa of the protrusion 251S when the gripping part of the assembly machine grips the support member 20S. This makes it easier for the gripping part of the assembly machine to grip the support member 20S, enabling the stable manufacture of heated tobacco cartridges. [Explanation of Symbols]
