Description

Technical Field

[0001] The present invention relates to a support member for a heated tobacco product used in a heated tobacco having a tobacco filler made of tobacco or non-tobacco plants, and a cartridge for a heated tobacco product having the same.

Background Art

[0002] In recent years, in order to conform to the trend of tobacco smoking bans, heated tobacco products for enjoying tobacco have begun to spread by heating a cartridge containing tobacco components without using a flame and sucking the vaporized tobacco components. A cartridge for a heated tobacco product has a tobacco filler that is inserted with a heating element such as a blade provided in the heated tobacco main body and heated, a filter provided at the suction port, and a support member provided between the tobacco filler and the filter, and these are formed by being wound with a packaging member such as paper. As such a support member for a heated tobacco product and a cartridge for a heated tobacco product, there is, for example, one as described in Patent Document 1.

[0003] Further, in the heated tobacco of Patent Document 2, a heating element is inserted into an aerosol-forming base material of a heated tobacco cartridge to heat the aerosol-forming base material and generate an aerosol containing tobacco components. The heated tobacco cartridge has a hollow tubular support member that supports the aerosol-forming base material, and the support member resists the force received by the cartridge when the heating element is inserted into the aerosol-forming base material. The tobacco components released from the aerosol-forming base material by heating are transferred through the hollow portion of the support member to a mouthpiece located downstream and sucked by the user.

Embodiments for Carrying Out the Invention

[0022] Hereinafter, embodiments of the present invention will be described with reference to the drawings and the like. However, the present invention can be implemented in many different modes, and is not to be construed as being limited to the description of the embodiments exemplified below. The drawings may be schematically represented for the sake of clarity of explanation, but are merely examples and do not limit the interpretation of the present invention.

[0023] Also, the letters "first" and "second" appended to each element are for convenience of distinguishing each element and have no further meaning unless otherwise specified. In the drawings referred to in this embodiment, the same parts or parts having the same function are given the same reference numerals or similar reference numerals (reference numerals obtained by simply attaching A, B, 1, 2, etc. to the numeral xxx), and repeated description thereof may be omitted. Also, a part of the configuration may be omitted from the drawings. In addition, what can be recognized by those having ordinary knowledge in the field to which the present invention pertains will not be specifically described.

[0024] As used in this specification, the term "tip" means, in the convex or concave portion provided on the peripheral surface of the support member, the top of the single point that protrudes highest from the peripheral surface in the case of the convex portion, and the deepest position of the single point that extends toward the center from the peripheral surface in the case of the concave portion. The shape of the top or the deepest part is not limited to being pointed, but also includes those having a rounded shape.

[0025] <First Embodiment> The 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. Configuration of the Heated Tobacco Cartridge) FIG. 1 is a cross-sectional view of a heated tobacco cartridge 1 having a tobacco filler aggregate 10 according to the present embodiment. As shown in FIG. 1, the heated tobacco cartridge 1 includes a tobacco filler aggregate 10, a support member 20 for heated tobacco (hereinafter simply referred to as the support member 20), a filter 30 serving as a 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 are integrated by being wound with the packaging member 40.

[0027] The tobacco filler aggregate 10 is formed such that a long tobacco filler 11 is bundled along the longitudinal direction D1 and becomes substantially cylindrical by being wound with a sheet-like wrapper. The tobacco filler 11 is formed of a non-tobacco material in this example. Note that the tobacco filler 11 may be formed of a tobacco material.

[0028] The tobacco filler 11 is formed by mixing a dried and pulverized non-tobacco plant with an aerosol former that generates an aerosol, microcrystalline cellulose, an additive for adding flavor, a preservative, an adhesive, or a thickener, etc., forming it into a sheet shape, and then cutting it to have a predetermined width and length. Note that the tobacco filler 11 is not limited to a long shape and may have various shapes. For example, it may be formed in a paste shape or a granular shape.

[0029] When the tobacco filler 11 is formed in a long shape, the cross-section perpendicular to the central axis C is substantially rectangular, and the ratio of the long side to the short side of the cross-section is preferably in the range of, for example, 1:1 to 30:1. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, 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, more preferably in the range of 0.1 mm to 0.5 mm. Also, the length of the tobacco filler 11 is preferably substantially the same as the length of the tobacco filler assembly 10. The length of the tobacco filler 11 is preferably in the range of 10 mm to 25 mm, more preferably in the range of 10 mm to 20 mm. As an example of the dimensions of such a tobacco filler 11, the long side is 1.5 mm, the short side is 0.3 mm, and the length is 12 mm.

[0030] The support member 20 suppresses the movement of the tobacco filler assembly 10 toward the support member 20 side and allows the airflow containing the aerosol generated in the tobacco filler assembly 10 to flow toward the filter 30 side. The support member 20 is provided, for example, in a cylindrical and solid shape, and is arranged between the tobacco filler 11 and the filter 30 such that its axial direction is along the central axis C. The support member 20 is formed, for example, to have a length along the central axis C in the range of 3.0 mm to 50 mm or less. Note that the support member 20 may have dimensions different from the above according to the 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 in the range of 6.5 mm to 7.5 mm and a length along the central axis C in the range of 50 mm or less. The filter 30 is a part that constitutes the suction port of the smoking implement cartridge 1. The filter 30 is formed using, for example, paper or the like. Also, the filter 30 may be provided in a cylindrical shape by winding a sheet-like member made of, for example, paper, or may contain a cellulose acetate filter or the like that removes fine particles. The filter 30 has a function of filtering a part of the fine particles in the water vapor and aerosol generated in the tobacco filler assembly 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. If the diameter of the heated tobacco cartridge 1 is set within the range of 6.5 to 7.5 mm, it will have a diameter smaller than the insertion hole for inserting the heated tobacco cartridge provided in the heated smoking device, making it easier to insert the heated tobacco cartridge 1 into the heated smoking device. If the length of the heated tobacco cartridge 1 is set within the range of 40 to 60 mm, since it will be longer than the length of the insertion hole for receiving the heated tobacco cartridge provided in the heated smoking device, even when the heated tobacco cartridge 1 is inserted into the smoking device, the suction port portion can be exposed from the heated smoking device, ensuring the length necessary for the smoker to smoke.

[0033] Also, the tobacco filler aggregate 10 has a length of 10 to 25 mm. If the length of the tobacco filler aggregate 10 is set to 10 mm or more, it is possible to ensure the minimum length required for inserting the heating element 52. Also, if the length of the tobacco filler aggregate 10 is set to 25 mm or less, it is possible to ensure a length that allows the heat of the heating element 52 to reach every corner of the tobacco filler 11. Note that the heated tobacco cartridge 1 may have dimensions different from the above according to the shape of the heated tobacco main body.

[0034] Figure 2 is a cross-sectional view showing the usage state of the heated tobacco cartridge 1. The heated tobacco cartridge 1 is used by being attached to the heated tobacco main body 5. The heated tobacco main body 5 has an insertion part 50 into which the heated tobacco cartridge 1 is inserted. In the insertion part 50, a needle-shaped or blade-shaped heating element 52 is provided which is inserted into the tobacco filling 11 of the inserted heated tobacco cartridge 1. The heating element 52 is electrically controlled by a control part provided inside the heated tobacco main body 5. The heating element 52 generates heat while being inserted into the tobacco filling 11, thereby enabling the generation of an aerosol from the tobacco filling 11. In this state, when the user sucks from the filter 30, an air flow containing the aerosol can be sucked. Further, the support member 20 is solid and is provided between the tobacco filling aggregate 10 and the filter, thereby preventing the tobacco filling aggregate 10 from moving toward the filter 30 side.

[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 peripheral face 25. The first end face 21 of the support member 20 abuts against the end face of the tobacco filling 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 referred to as a through-hole) extending from the first end face 21 to the second end face 23, and an air flow passes through the hole 27. The support member 20 is provided in a cylindrical shape. For example, a silicone resin is used as the material forming the support member 20. Note that the support member 20 is not limited to a silicone resin and may be formed of a material other than a resin material such as wood or metal (such as aluminum) that increases the cooling effect.

[0037] FIG. 4(A) is a side view of the support member 20. FIG. 4(B) is a view with the first end face 21 of the support member 20 as the front. As shown in FIGS. 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 the cross-sectional shape cut by a plane orthogonal to the longitudinal direction D1.

[0038] The support member 20 has a hole 27 penetrating from the first end face 21 to the second end face 23. The hole 27 functions as a flow path for allowing the airflow containing the aerosol generated in the tobacco filler aggregate 10 to flow toward the filter 30 side.

[0039] As shown in FIGS. 4(A) and 4(B), the hole 27 is arranged so as not to include the central axis C20 of the peripheral surface portion 25. In this example, the hole 27 has a cylindrical shape. Also, in the present embodiment, six holes 27 are provided along the circumferential direction. At this time, the centers P of the holes 27 are arranged at intervals of 60° in the circumferential direction with the central axis C20 as the center. For this reason, 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 at the portion of the hole 27 and is solid at the other portions. This solid portion abuts against the end face of the tobacco filler aggregate 10. Since the tobacco filler aggregate 10 receives a force in the longitudinal direction D1 when the heating element 52 of the heat-not-burn tobacco body 5 is inserted, the tobacco filler aggregate 10 can be supported by the solid portion of the support member 20 that abuts.

[0041] The support member 20 has a plurality of convex portions 251 on the peripheral surface portion 25. The convex portions 251 are provided so as to extend along the longitudinal direction D1. In this example, the convex portions 251 are formed so as to span the entire longitudinal length D1 from the first end face 21 to the second end face 23 of the peripheral surface portion 25 of the support member 20. Also, a plurality of convex portions 251 are provided over the entire circumference in the circumferential direction.

[0042] The plurality of convex portions 251 each have a tip portion 251a. In this example, the tip portion 251a has a round shape. In FIG. 4(B), a virtual line VL1 extending from the center C251 of the convex portion 251 toward the tip portion 251a when viewed from the first end face 21 side is the same as a virtual line extending in the radial direction D2 from the central axis C20 of the support member 20. The convex portion 251 has two side portions S251, and the two side portions S251 connect the tip portion 251a and the peripheral surface portion 25, respectively. At this time, when the support member 20 is viewed from the first end face 21 side, the angle θ formed by the virtual line VL1 and a virtual line VL2 provided along the side portion S251 corresponding to the tip portion 251a of the convex portion 251 is an acute angle.

[0043] In the present embodiment, by providing the convex portion 251 on the peripheral surface portion 25, when the gripping portion of the assembly machine grips the support member 20, a frictional force is generated between the gripping portion of the assembly machine and the tip portion 251a of the convex portion 251. As a result, the gripping portion of the assembly machine can easily grip the support member 20, and the heating tobacco cartridge can be stably manufactured.

[0044] FIG. 5 is a cross-sectional view of a state in which the support member 20 is wrapped by the packaging member 40. As shown in FIG. 5, in the present embodiment, a gap 26 is provided by providing the convex portion 251 between the packaging member 40 wound around the outer periphery of the support member 20 and the peripheral surface portion 25 of the support member 20. As a result, the aerosol gas can flow between the packaging member 40 and the peripheral surface portion 25. Therefore, the flow path of the aerosol gas is enlarged in addition to the hole portion 27, and the fluidity of the aerosol gas can be improved. Further, in the case of the present embodiment, since the gap 26 has a shape that expands toward the packaging member 40, the aerosol flow path can be made larger than, for example, when the convex portion has a substantially square shape. can be taken.

[0045] In addition, in the present embodiment, the convex portions 251 have the same height in the longitudinal direction D1. At this time, the height of the convex portion 251 is preferably 0.05 mm or more and 1 mm or less. This is because when the height of the convex portion 251 is less than 0.05 mm, it becomes difficult to maintain the shape as a convex portion, or the aerosol may not flow smoothly. Further, when the height of the convex portion 251 exceeds 1 mm, the size of the gap between the support member 20 and the packaging member 40 increases, and a part of the tobacco filler 11 may enter the gap, making it difficult to suppress the movement of the tobacco filler assembly 10 toward the filter 30 side. Also, from the viewpoint of maintaining the shape of the convex portion, the above range is desirable.

[0046] In addition, in the present embodiment, together with the porosity between the peripheral surface portion 25 and the packaging member 40, the support member 20 can adjust the fluidity of the aerosol (airflow) from the tobacco filler assembly 10 by adjusting the porosity, which is the ratio of the cross-sectional area of the through-hole to the cross-sectional area of the support member 20. Details of the porosity will be described later.

[0047] When the support member 20 of the present embodiment is packaged with the packaging member 40, a plurality of gaps 26 are provided between the peripheral surface portion 25 and the packaging member 40, and these gaps can be used as the flow path of the aerosol. The gaps at the first end surface of the support member 20 are the gaps 26 and the six hole portions 27, and the ratio of the porosity of the gap 26 to the porosity of the hole portion 27 is preferably in the range of 1:1 to 1:12, for example. The porosity of the gap 26 is preferably in the range of 1% to 5% of the area surrounded by the packaging member 40, and the porosity of the hole portion 27 is preferably in the range of 1% to 60%. When the gap 26 exceeds the upper limit of the above range, when pressure is applied from the outside, the packaging member 40 may be crushed, and the shape of the entire cartridge may not be maintained, or the support function of the support member 20 may not be maintained (for example, the tobacco filler assembly may easily enter the gap 26 and the hole portion 27). Further, when the gap 26 is below the lower limit of the above range, there is a risk of impairing the flow of the aerosol (for example, the flow path becomes narrow, and the flow rate of the aerosol decreases, so more force is required for suction).

[0048] That is, by using this embodiment, when pressure is applied from the outside, the packaging member 40 will not be crushed, the solid portion of the support member 20 suppresses the movement of the tobacco filler aggregate 10 toward the support member 20 side, and a plurality of gaps 26 are provided between the packaging member 40. Thus, in addition to the holes 27, the aerosol can flow through the gaps of the gaps 26, enhancing the effect of allowing the aerosol to flow.

[0049] Also, in conjunction with the porosity, the ventilation resistance may be adjusted according to the thickness and material of the packaging member 40. In this embodiment, since the gap 26 is provided between the packaging member 40 and the support member 20, when the inside of the packaging member 40 becomes a negative pressure state by sucking the filter 30, outside air is taken in through the packaging member 40. At this time, the degree of outside air intake can be changed by the ventilation resistance of the packaging member 40.

[0050] <Second Embodiment> In the first embodiment of the present invention, an example in which the convex portion extends in the longitudinal direction of the peripheral surface portion in the support member is shown, 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 convex portion is provided in a direction inclined with respect to the longitudinal direction will be described. In this embodiment, for the same configurations as those in the first embodiment, the description will be omitted as appropriate.

[0051] FIG. 6 is a side view of the support member 20A. As shown in FIG. 6, the support member 20A has a convex portion 251A on the peripheral surface portion 25A. The convex portion 251A may extend in a direction intersecting the longitudinal direction D1. Specifically, the convex portion 251A is provided in a direction inclined with respect to the longitudinal direction D1. In this case, compared with the case where the convex portion 251A extends in the longitudinal direction D1, the flow path of the aerosol becomes longer, and the cooling time can be increased. Therefore, by using this embodiment, the gripping portion (manufacturing apparatus) of the assembly machine can easily grip the support member 20A, and the heated tobacco cartridge can be stably manufactured, and the convex portion 251A is linear It is possible to change the suction feeling when inhaling the aerosol as compared with the case where it is provided in

[0052] <Third Embodiment> In the first embodiment of the present invention, an example in which a convex portion extends in the longitudinal direction of the circumferential surface portion in the support member has been shown, but the present invention is not limited thereto. In the present embodiment, a support member different from the first embodiment will be described. Specifically, a support member having a convex portion arranged in a curved shape will be described. In the present embodiment, descriptions of the same configurations as those in the first embodiment will be omitted as appropriate.

[0053] FIG. 7 is a side view of the support member 20B. As shown in FIG. 7, in the circumferential surface portion 25B of the support member 20B, the convex portion 251B may have a tip portion and may be arranged in a curved shape from the first end surface 21 toward the second end surface 23. In this case, the flow path of the aerosol can be lengthened as compared with the case where the convex portion 251B extends linearly in the longitudinal direction D1. As a result, it becomes easier for the manufacturing machine (assembly machine) to grip, and the heating cigarette cartridge can be stably manufactured, and it is possible to change the suction feeling when the smoker inhales the aerosol as compared with the case where the convex portion is provided linearly.

[0054] <Fourth Embodiment> In the present embodiment, a support member different from the first embodiment will be described. Specifically, a support member in which the convex portion is provided in a wave shape from the first end surface to the second end surface will be described. In the present embodiment, descriptions of the same configurations as those in the first embodiment will be omitted as appropriate.

[0055] FIG. 8(A) is a side view of the support member 20C. FIG. 8(B) is a view with the first end face 21 of the support member 20C as the front. As shown in FIGS. 8(A) and 8(B), in the support member 20C, the convex portion 251C may be arranged in a wave shape in the longitudinal direction D1 from the first end face 21 toward the second end face 23. In this case, the flow path of the aerosol can be made longer than when the convex portion 251C extends linearly in the longitudinal direction D1. Thereby, the cooling time of the aerosol also changes. Therefore, by using the present embodiment, the gripping portion (manufacturing apparatus) of the assembly machine can easily grip the support member 20C, and the heated tobacco cartridge can be stably manufactured. In addition, compared with the case where the convex portion 251C is provided linearly, it is possible to change the smoking feeling when a smoker inhales the aerosol.

[0056] <Fifth Embodiment> In the present embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member provided with convex portions along the circumferential direction will be described. In the present embodiment, descriptions of the same configurations as those in the first embodiment will be omitted as appropriate.

[0057] FIG. 9(A) is a side view of the support member 20D. FIG. 9(B) is a view with the first end face 21 of the support member 20D as the front. As shown in FIGS. 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 convex portion 251D. The convex portion 251D has a tip portion 251Da and may be provided along the circumferential direction. At this time, in FIG. 9(A), a virtual line VL1 extending from the center C251D of the convex portion 251D toward the tip portion 251Da is the same as a virtual line extending in the radial direction D2 from the central axis C20D of the support member 20D. The convex portion 251D has two side portions S251D, and the two side portions S251D connect the tip portion 251Da and the circumferential surface portion 25D, respectively. At this time, when the support member 20D is viewed from the circumferential surface portion 25D side, an angle θ formed by the virtual line VL1 and a virtual line VL2 provided along the side portion S251D corresponding to the tip portion 251Da of the convex portion 251D is an acute angle.

[0058] The number of the convex portions 251D is controlled by the length of the support member 20D in the longitudinal direction. In the case of the present embodiment, the number of the convex portions 251D that come into contact with the gripping portion of the assembly machine increases as compared with the case where the convex portion 251 extends in the longitudinal direction D1. When the number of the convex portions 251D that come into contact increases, a large frictional force is likely to be generated when the gripping portion of the assembly machine comes into contact with the support member 20D. Therefore, by using the present embodiment, the gripping portion (manufacturing apparatus) of the assembly machine can easily grip the support member 20D, and the cartridge for heating tobacco can be stably manufactured.

[0059] <Sixth Embodiment> In the present embodiment, a support member different from that of the first embodiment will be described. Specifically, a support member in which a plurality of convex portions are provided so as to intersect each other will be described. In the present embodiment, descriptions of the same configurations as those of the first embodiment will be omitted as appropriate.

[0060] FIG. 10(A) is a side view of the support member 20E. FIG. 10(B) is a view with the first end face 21 of the support member 20E as the front. As shown in FIGS. 10(A) and 10(B), the support member 20E includes a plurality of convex portions 251E on the peripheral surface portion 25E. The convex portion 251E has a convex portion 251E1 and a convex portion 251E2. The convex portion 251E1 has a tip portion 251E1a and is provided along the longitudinal direction D1. The convex portion 251E2 has a tip portion 251E2a and is provided along the circumferential direction. The convex portion 251E1 and the convex portion 251E2 may be provided so as to intersect each other.

[0061] At this time, the height of the convex portion 251E1 and the height of the convex portion 251E2 may be different. In this example, the height of the convex portion 251E2 is larger than the height of the convex portion 251E1. Thereby, the number of the convex portions 251E that come into contact with the gripping portion of the assembly machine increases. When the number of the convex portions that come into contact increases, a large frictional force is likely to be generated when the gripping portion of the assembly machine comes into contact with the support member 20E.

[0062] In the case of the present embodiment, the convex portion 251E1 and the circumferential convex portion 251E2 intersect to form a lattice-shaped groove 251EV. The aerosol can partially stay in the groove 251EV. As a result, the flow path of the aerosol diversifies and the cooling time of the aerosol can be varied. Therefore, by using the present embodiment, the gripping portion (manufacturing apparatus) of the assembly machine can easily grip the support member 20E, the heating cigarette cartridge can be stably manufactured, and it is possible to change the smoking feeling when a smoker inhales the aerosol as compared with the case where the convex portion is provided linearly.

[0063] <Seventh Embodiment> In the first embodiment of the present invention, an example in which the support member is provided with irregularities over the entire length in the longitudinal direction D1 and the entire circumferential direction of the circumferential surface portion 25 has been shown, but the present invention is not limited to this. In the present embodiment, a support member 20 different from the first embodiment will be described. A support member 20 in which the convex portion 251 is provided in a partial region of the circumferential surface portion 25 will be described.

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

[0065] At this time, as shown in FIG. 11(A), it may be provided wider in the circumferential direction than in the longitudinal direction D1. Also, as shown in FIG. 11(B), it may be provided wider in the longitudinal direction D1 than in the circumferential direction.

[0066] Further, the support member 20F may be provided in a plurality of regions. For example, as shown in FIG. 12(A), when the convex portion 251F is provided wide in the circumferential direction, the convex portion 251F may be provided in a plurality of regions in the longitudinal direction D1. Also, as shown in FIG. 12(B), when the convex portion 251 is provided wide in the longitudinal direction D1, the convex portion 251F may be provided in a plurality of regions in the circumferential direction.

[0067] Further, as shown in Fig. 13(A), the convex portion 251F may be provided over the entire circumference in the circumferential direction of a part of the circumferential surface portion 25F. At this time, as shown in Fig. 13(B), the convex portion 251F may be provided in a plurality of regions in the longitudinal direction D1.

[0068] Further, as shown in Fig. 14(A), the convex portion 251F may be provided over the entire length in the longitudinal direction D1 of a part of the circumferential surface portion 25F. At this time, as shown in Fig. 14(B), the convex portion 251F may be provided in a plurality of regions in the circumferential direction.

[0069] Also in the configuration of the present embodiment, since the convex portion 251F is provided on the circumferential surface portion 25F, a frictional force is likely to be generated when the assembly machine grips the support member 20F. As a result, the gripping portion of the assembly machine can easily grip the support member 20F, and the heating cigarette cartridge can be stably manufactured.

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

[0071] Fig. 15(A) is a side view of the support member 20G. Fig. 15(B) is a view with the first end surface 21 of the support member 20G as the front. As shown in Fig. 15(A) and Fig. 15(B), the circumferential surface portion 25G has a convex portion 251G. The convex portion 251G has a protruding shape. The convex portion 251G is arranged in the longitudinal direction D1 and the circumferential direction. The convex portion 251G has tip portions 251Ga, respectively. In Fig. 15(B), a virtual line VL1 extending from the center C251G of the convex portion 251 toward the tip portion 251Ga when viewed from the first end surface side is the same as a virtual line extending in the radial direction D2 from the central axis C20G of the support member 20G. The convex portion 251G has two side portions S251 It has G, and the two side portions S251G connect the tip portion 251Ga and the circumferential surface portion 25G respectively. At this time, when the support member 20G is viewed from the side of the first end face 21, the angle θ formed by the virtual line VL1 and the virtual line VL2 provided along the side portion S251G corresponding to the tip portion 251Ga of the convex portion 251G is an acute angle.

[0072] In the case of this embodiment, the convex portions 251G are provided in the same number as the number of protrusions, and the frictional force between the support member 20G when manufacturing the heated tobacco cartridge and the gripping portion of the assembly machine can be increased. Thereby, the gripping portion of the assembly machine can easily grip the support member 20G, and the cartridge for heated tobacco can be stably manufactured.

[0073] In addition, in this embodiment, an example in which the adjacent convex portions 251G are arranged in the longitudinal direction D1 is shown, but the present invention is not limited to this. For example, the other convex portion 251G adjacent to one convex portion 251G may be arranged in a direction intersecting the longitudinal direction D1.

[0074] FIG. 16(A) is a side view of the support member 20H. FIG. 16(B) is a view with the first end face 21 of the support member 20H as the front. As shown in FIG. 16(A), the convex portion 251H may be arranged in a zigzag shape in an oblique direction with respect to the longitudinal direction D1, for example. At this time, as shown in FIG. 16(B), when viewed from the side of the first end face 21, the adjacent convex portions 251H partially overlap. Thereby, the flow path of the aerosol becomes longer than when the aerosol flows linearly. Therefore, the cooling time of the aerosol varies. Accordingly, it becomes easier for the assembly machine to grip, and the cartridge for heated tobacco can be stably manufactured, and it is possible to change the smoking feeling when the smoker inhales the aerosol.

[0075] <Ninth Embodiment> In the first embodiment of the present invention, an example in which a convex portion extends in the longitudinal direction of the peripheral surface portion in the support member has been shown, but the present invention is not limited to this. In the present embodiment, a support member different from the first embodiment will be described. Specifically, a support member having a concave portion extending in the longitudinal direction in the peripheral surface portion will be described. In the present embodiment, descriptions of the same configurations as those in the first embodiment will be omitted as appropriate.

[0076] FIG. 17(A) is a side view of the support member 20J. FIG. 17(B) is a view with the first end face 21 of the support member 20J as the front. As shown in FIGS. 17(A) and 17(B), in the support member 20J, the peripheral surface portion 25J has a concave portion 252. The concave portion 252 is linearly arranged in the longitudinal direction D1 from the first end face 21 toward the second end face 23.

[0077] In FIG. 17(B), the concave portion 252 has two side portions S252, and the two side portions S252J connect the tip portion 252a and the peripheral surface portion 25J, respectively. At this time, when the support member 20J is viewed from the first end face 21 side, an angle θ formed by a virtual line VL1 extending from the center C252 of the concave portion 252 toward the tip portion 252a when viewed from the first end face 21 side and a virtual line VL2 provided along the side portion S252 corresponding to the tip portion 252a of the concave portion 252 is an acute angle.

[0078] In the case of the present embodiment, since the support member 20J has the concave portion 252, the tip of the gripping portion of the assembling machine is likely to be caught by the support member 20J. As a result, the gripping portion of the assembling machine can easily grip the support member 20J, and a heating tobacco cartridge can be stably manufactured.

[0079] In the present embodiment, an example in which the concave portion 252 is linearly arranged in the longitudinal direction D1 from the first end face 21 toward the second end face 23 has been shown, but it may be provided in accordance with the shapes described in the second to seventh embodiments and the like.

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

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

[0082] In the case of the present embodiment, since the support member 20K has a plurality of recessed portions 252K, the tip of the gripping portion of the assembly machine is likely to be caught in the recessed portion 252K of the support member 20K. As a result, the gripping portion of the assembly machine can easily grip the support member 20K, and the heating cigarette cartridge can be stably manufactured.

[0083] Further, in the case of the present embodiment, the aerosol stays in the recessed portion 252K, so that the flow path of the aerosol changes. Thereby, it is possible to change the smoking feeling when a smoker inhales the aerosol.

[0084] <Eleventh Embodiment> In the present embodiment, a support member different from the first embodiment will be described. Specifically, a support member provided with a plurality of fine convex portions in the circumferential direction will be described. In the present embodiment, the description of the same configuration as that in the first embodiment will be omitted as appropriate.

[0085] FIG. 19(A) is a side view of the support member 20L. FIG. 19(B) is a view of the first end face 21 of the support member 20L as a front view and a partial enlarged view. As shown in FIGS. 19(A) and 19(B), a plurality of fine convex portions 251L may be arranged in the longitudinal direction D1 from the first end face 21 toward the second end face 23 on the circumferential surface portion 25L of the support member 20L. The fine convex portion 251L has a shape with a pointed tip portion 251La.

[0086] The support member 20L has six hole portions 27L (through holes). Among the six through holes, five through holes are separated from each other by 72 degrees in the circumferential direction and are evenly arranged. Among the six through holes, the remaining one through hole is arranged at the center of the first end face 21.

[0087] In the present embodiment, 100 or more and 150 or less fine convex portions 251L may be arranged in the circumferential direction. Also, the height of the fine convex portion 251L may be 1 / 100 or more and 1 / 50 or less with respect to the width (diameter) of the support member. In this example, 137 fine convex portions 251L are arranged in the circumferential direction. At this time, the diameter of the support member is 7 mm, and the height T251L of the convex portion 251L is 0.1 mm. The width W251La (also referred to as the pitch) between the tip portions 251La of adjacent convex portions 251L is 0.16 mm.

[0088] By having the present embodiment, the ground contact area (contact points) with the member to be gripped while maintaining the shape of the convex portion increases. Thereby, the frictional force between the gripping portion of the assembly machine and the support member can be increased. Therefore, it becomes easier to grip the support member with the gripping portion of the assembly machine.

[0089] Also, when the support member of the present embodiment is wrapped with a packaging member, a plurality of gaps 26 are provided between the peripheral surface portion 25L and the packaging member 40, and these gaps can be used as the flow path of the aerosol. At this time, the gaps at the first end surface of the support member 20L are the gap 26 and the six hole portions 27L. The ratio of the porosity of the gap 26 to that of the hole portion 27L is preferably in the range of, for example, 1:1 to 1:12. The porosity of the gap 26 is preferably in the range of 2% to 4% of the area surrounded by the packaging member 40, and the porosity of the hole portion 27L is preferably in the range of 2% to 48%. When the gap 26 exceeds the upper limit of the above range, when pressure is applied from the outside, the packaging member 40 may be crushed, and the shape of the entire cartridge cannot be maintained, or the support function of the support member 20 may not be maintained (for example, the tobacco filler 11 of the tobacco filler assembly 10 may easily enter the gap 26 and the hole portion 27). Also, when the gap 26 is below the lower limit of the above range, there is a risk of impairing the flow of the aerosol (for example, the flow path becomes narrow, and the flow rate of the aerosol decreases, so more force is required for suction). In the present embodiment, the porosity of the hole portion 27 is 30%, and the porosity of the gap 26 is 3%.

[0090] That is, by using the present embodiment, the solid portion of the support member 20L suppresses the movement of the tobacco filler assembly 10 toward the filter 30 side, and a plurality of gaps 26 are provided between the support member 20L and the packaging member 40. Thus, in addition to the hole portion 27L, the aerosol flows through the gap of the gap 26, and the effect of allowing the aerosol to flow can be enhanced.

[0091] (Modification example) Those skilled in the art can conceive of various modification examples and correction examples within the scope of the idea of the present invention, and it is understood that those modification examples and correction examples also belong to the scope of the present invention. For example, for each of the above-described embodiments, those obtained by appropriately adding, deleting, or changing the design of components by those skilled in the art, or by adding, omitting, or changing the conditions of the process, also fall within the scope of the present invention as long as they have the gist of the present invention. Also, the configurations of the respective embodiments may be used in appropriate combination.

[0092] In the first embodiment of the present invention, an example is shown in which the heated tobacco cartridge 1 is provided with a tobacco filler aggregate 10, a support member 20, and a filter 30 serving as a suction port. However, the present invention is not limited to this. Another member such as a cooling member or a heat insulating member may be provided between the support member 20 and the filter 30. Further, there may be a cavity for improving air permeability between the support member and the filter. At this time, the cavity may be provided in the range of 1 mm or more and 20 mm or less. As a result, since the cavity portion is provided widely, the suction amount of the aerosol generated by the heated aroma generating body can be improved. Also, since the cavity functions as an alternating current space, it is excellent in terms of taste. Furthermore, even when problems such as the tea leaves and the filter becoming slightly longer due to manufacturing errors occur, the manufacturing defects can be absorbed by providing this cavity.

[0093] Further, the heated tobacco cartridge 1 may be composed of only the tobacco filler aggregate 10 and the support member 20. In this case, the heated tobacco cartridge 1 may not have a filter.

[0094] In the first embodiment of the present invention, an example is shown in which the hole 27 (through hole) has the same radius and has a circular shape, but the present invention is not limited to this. The holes 27 may have different radii. Also, the hole 27 may be elliptical or rectangular.

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

[0096] Note that, in the first embodiment of the present invention, an example is shown in which a plurality of convex portions or concave portions are provided, but the present invention is not limited to this. By providing at least one convex portion or concave portion, the problems of the present application can be solved.

[0097] In the first embodiment of the present invention, an example in which the convex portions 251 have the same height has been shown, but the present invention is not limited thereto. The convex portions 251 may have different heights. Further, when the convex portions 251 extend in the longitudinal direction D1, the heights of the convex portions 251 may be different in the longitudinal direction D1. Further, when the convex portions 251 extend along the circumferential direction, the heights of the convex portions 251 may be different in the circumferential direction. Further, the heights of adjacent convex portions 251 may be different. Thereby, the flow path of the aerosol diversifies. Therefore, it is possible to change the feel of inhaling the aerosol obtained in the heated tobacco cartridge.

[0098] In the first embodiment of the present invention, an example in which the virtual line VL1 extending from the center of the convex portion 251 toward the tip portion 251a when viewed from the first end face side is the same as the virtual line extending in the radial direction D2 from the central axis C20 of the support member 20 has been shown, but the present invention is not limited thereto. FIG. 20 is a view with the first end face 21 of the support member 20M as the front. As shown in FIG. 20, the peripheral surface portion 25M of the support member 20M has convex portions 251M. The virtual line VL1 extending from the center C251M of the convex portion 251M toward the tip portion 251Ma may be different from the virtual line VL3 extending in the radial direction from the central axis C20M of the support member 20M. In this case, it is desirable that the angle formed by the two virtual lines VL1 and VL3 is less than 5 degrees. Thereby, the same effect as the case where the center and the tip portion 251a of the convex portion 251 of the first embodiment are provided on the same virtual line can be obtained.

[0099] Further, in the fourth embodiment of the present invention, an example in which the convex portion 251C is arranged to have a wave shape in the longitudinal direction D1 has been shown, but the present invention is not limited thereto. The convex portions 251N of the support member 20N may be arranged in the circumferential direction or may be arranged in an oblique direction with respect to the longitudinal direction D1. FIG. 21 is a side view of the support member 20N. For example, as shown in FIG. 21, the convex portions 251N may be arranged to have a wave shape in a direction intersecting the longitudinal direction D1.

[0100] In addition, in the sixth embodiment of the present invention, an example in which a plurality of convex portions 251 are provided so as to intersect in the longitudinal direction D1 and the circumferential direction has been shown, but the present invention is not limited thereto. For example, a part of the plurality of convex portions 251E may extend in a direction inclined with respect to the longitudinal direction D1 or the circumferential direction. The convex portion 251E may intersect in the longitudinal direction D1 and the circumferential direction and may have a waveform. Thereby, the flow path of the aerosol is diversified, and it is possible to change the sucking feeling when a smoker sucks in the aerosol.

[0101] In addition, in each embodiment of the present invention, an example in which a concave portion or a convex portion is provided with a certain regularity has been shown, but the present invention is not limited thereto. FIG. 22 is a side view of the support member 20P. As shown in FIG. 22, the support member 20P has a convex portion 251P on the circumferential surface portion 25P. The convex portion 251P may be provided irregularly. At this time, by providing the convex portion 251P, a frictional force is generated between the gripping portion of the assembling machine and the convex portion, the flow path of the aerosol is diversified, and it is possible to change the sucking feeling when a smoker sucks in the aerosol. Therefore, it becomes easier for the assembling machine to grip, the heating tobacco cartridge can be stably manufactured, and the sucking feeling of the aerosol can be made different.

[0102] In addition, in one embodiment of the present invention, an example having a tip portion has been shown, but the present invention is not limited thereto. FIG. 23 is a cross-sectional view of the support member 20Q and an enlarged view of the convex portion 251Q. As shown in FIG. 23, the upper portion 251Qu of the convex portion 251Q on the circumferential surface portion 25Q of the support member 20Q may be flat. At this time, when the support member 20 is viewed from the first end face 21 side, it is desirable that the width W251Qu of the upper portion 251Qu of the convex portion 251Q is 1 / 5 or less of the width W251Qd of the lower portion 251Qd of the convex portion 251. Thereby, the same effect as when the convex portion has a tip portion (top portion) can be obtained.

[0103] In addition, in the first embodiment of the present invention, an example in which one convex portion has a tip portion with one top portion formed thereon has been shown, but the present invention is not limited thereto. FIG. 24 is a cross-sectional view of the support member 20R and an enlarged view of the convex portion 251R. As shown in FIG. 24, the support member 20R has a convex portion 251R on the circumferential surface portion 25R. The convex portion 251R may have a tip portion 251Ra on which a plurality of top portions are formed. At this time, the angle formed by the virtual line VL1R connecting the center C251R of the convex portion and one top portion 251Ra1 at the tip portion 251Ra and the virtual line VL2R provided along the side portion S251R corresponding to the top portion 251Ra1 is an acute angle. Thereby, the grounding area (contact point) with the member to be gripped increases. Therefore, the frictional force between the gripping portion of the assembly machine and the support member can be increased. Accordingly, it becomes easier to grip the support member with the gripping portion of the assembly machine.

[0104] Further, in the first embodiment of the present invention, an example in which the convex portion has two side portions when the first end face 21 is taken as the front has been described, but the present invention is not limited thereto. The convex portion may have an arc.

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

[0106] In this embodiment, by providing the convex portion 251S on the peripheral surface portion 25S, when the gripping portion of the assembly machine grips the support member 20S, a frictional force is generated between the gripping portion of the assembly machine and the tip end portion 21Sa of the convex portion 251S. As a result, the gripping portion of the assembly machine can easily grip the support member 20S, and the cartridge for heating tobacco can be stably manufactured.
