Description

[Technical Field]

[0001] The present invention relates to a support member for a heated tobacco product having a tobacco filler made from tobacco or a non-tobacco plant, and a cartridge for a heated tobacco product having the same. [Background technology]

[0002] In recent years, in line with the trend toward smoking cessation, heated tobacco products have become popular, allowing people to enjoy tobacco by heating a cartridge containing tobacco components without using a flame and inhaling the vaporized tobacco components. A heated tobacco cartridge comprises a tobacco filler that is heated by inserting a heating element such as a blade of a heated tobacco product body, a filter provided at the mouthpiece, and a support member provided between the tobacco filler and the filter, and is formed by wrapping these components in a packaging material such as paper. Examples of such heated tobacco support members and heated tobacco cartridges include those listed in Patent Document 1.

[0003] In addition, in the heated tobacco product of Patent Document 2, a heating element is inserted into the aerosol-forming substrate of a heated tobacco cartridge to heat the aerosol-forming substrate and generate an aerosol containing tobacco components. The heated tobacco cartridge has a hollow tubular support member that supports the aerosol-forming substrate, and the support member resists the force that the cartridge receives when the heating element is inserted into the aerosol-forming substrate. The tobacco components released from the aerosol-forming substrate by heating are transported through the hollow part of the support member to a mouthpiece located downstream and are inhaled by the user. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3212228 [Patent Document 2] Patent No. 6000451 Summary of the Invention [Problem to be solved by the invention]

[0005] The heated tobacco support member allows airflow from the tobacco filler to pass through, and supports the tobacco filler from one end to prevent the filler from collapsing when a heating element is inserted into the tobacco filler. For this purpose, the heated tobacco support member has a hole that penetrates it in the length direction, and supports the tobacco filler in the remaining part.

[0006] In a cross section of the heated tobacco support member cut along a plane perpendicular to the longitudinal direction, the area of ​​the holes is a void. If the void ratio in the cross section is high, the fluidity of the airflow from the tobacco filler toward the mouthpiece can be improved, but if the void ratio is too high, the function of supporting the tobacco filler is reduced. Furthermore, the positioning of the holes in the cross section affects the function of supporting the tobacco filler. Therefore, by optimizing the shape and positioning of the holes, it is possible to achieve both good fluidity of the airflow and the function of supporting the tobacco filler.

[0007] The present invention has been made in consideration of the above-mentioned problems, and aims to provide a heated tobacco support member and a heated tobacco cartridge in which the shape and arrangement of the holes are optimized.

[0008] Furthermore, in the heated tobacco product of Cited Document 2, the support member is hollow and tubular, and therefore when the heating element is inserted into the aerosol-forming substrate, it may not be able to fully support the center of the aerosol-forming substrate, which could result in the filler spilling out into the support member. If the porosity of the support member is high, the fluidity of the airflow from the aerosol-forming substrate toward the mouthpiece can be improved, but if the porosity is too high, the function of supporting the aerosol-forming substrate is reduced. Therefore, it is necessary for the support member to achieve both the fluidity of the airflow and the function of supporting the aerosol-forming substrate.

DETAILED DESCRIPTION OF THE INVENTION

[0044] An embodiment of the present invention will be described in detail with reference to the drawings. Fig. 1 shows a cross-sectional view of a heated tobacco cartridge 1 having a tobacco filler assembly 10 in this embodiment. As shown in this figure, the heated tobacco cartridge 1 is formed by arranging a substantially cylindrical tobacco filler assembly 10 filled with a large number of tobacco fillers 20, a heated tobacco support member 12 (hereinafter simply referred to as the support member 12), and a filter 14 serving as a mouthpiece along the length direction and wrapping them together in a sheet-like packaging member 16.

[0045] The tobacco filler assembly 10 is formed by bundling long strips of tobacco filler 20 along their length and wrapping them in a sheet-like wrapping material 25 to form a substantially cylindrical shape. The tobacco filler 20 is made from a non-tobacco plant. However, the tobacco filler 20 may also be made from tobacco.

[0046] The tobacco filler 20 is formed by mixing dried and ground non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, adhesives or thickeners, etc., forming the mixture into a sheet, and then cutting the sheet into a predetermined width and length. However, the tobacco filler 20 may also be formed into a dust form.

[0047] The support member 12 allows the airflow containing the aerosol generated in the tobacco filler accumulation 10 to flow toward the filter 14. A first end face 30 of the support member 12 abuts against the end face of the tobacco filler accumulation 10, and a second end face 31 of the support member 12 abuts against the end face of the filter 14. The support member 12 has holes 40 extending from the first end face 30 to the second end face 31, and the airflow flows through the holes 40. The filter 14 is a sponge-like porous body formed in a cylindrical shape.

[0048] In this embodiment, the heated tobacco cartridge 1 is formed to have a diameter of 6.5 to 7.5 mm and a length of 40 to 49 mm. The tobacco filler assembly 10 has a length of 11 to 13 mm. However, it may have other dimensions.

[0049] FIG. 1 shows a cross-sectional view illustrating a usage form of a heated tobacco cartridge 1. The heated tobacco cartridge 1 is used by being attached to a heated tobacco body 2. The heated tobacco body 2 has an insertion section 51 into which the heated tobacco cartridge 1 is inserted. The insertion section 51 is provided with a needle-shaped or blade-shaped heating section 50 that is inserted into the tobacco filler 20 of the inserted heated tobacco cartridge 1. The heating section 50 generates heat while inserted into the tobacco filler 20, thereby generating an aerosol from the tobacco filler 20. In this state, the user can inhale an airflow containing the aerosol by inhaling through the filter 14.

[0050] The support member 12 will be described in detail. Fig. 2 shows a perspective view of the support member 12. The support member 12 is a cylindrical member made of a resin material. Examples of the resin material that forms the support member 12 include silicone. However, the support member 12 may be made of other resin materials, or materials other than resin materials such as wood or metal (aluminum, etc.) that have a greater cooling effect.

[0051] 2, the support member 12 has a first end face 30, a second end face 31, and a peripheral surface portion 32. The support member 12 has a hole portion 40 that penetrates from the first end face 30 to the second end face 31. The hole portion 40 functions as a flow path that allows the airflow containing the aerosol generated in the tobacco filler assembly 10 to flow toward the filter 14.

[0052] 3 is a front view of the first end face 30 of the support member 12. In a cross section of the support member 12 taken along a plane perpendicular to the longitudinal direction, the shape is the same from the first end face 30 to the second end face 31. Therefore, the cross section is also the same as that shown in FIG.

[0053] As shown in FIG. 3, the hole portion 40 has first through holes 41 arranged on the outer periphery so as not to include the central axis C of the peripheral surface portion 32. The first through holes 41 are elliptical in shape and are longer in the circumferential direction than in the radial direction of the support member 12. Three first through holes 41 are provided along the circumferential direction. The ellipse centers P of the first through holes 41 are each located on an imaginary circle V having a constant radius from the central axis C. Furthermore, the ellipse centers P are arranged at intervals of 120° in the circumferential direction around the central axis C. Therefore, the three first through holes 41 are arranged at equal intervals in the circumferential direction.

[0054] The first end face 30 has a void at the hole 40 and a solid portion at the other end, which abuts against the end face of the tobacco filler assembly 10. When the heating unit 50 of the heated tobacco body 2 is inserted, the tobacco filler assembly 10 receives a force in the longitudinal direction, and the abutting solid portion of the support member 12 can support the tobacco filler assembly 10. The hole 40 of this embodiment is disposed on the outer periphery of the support member 12 so as not to include the central axis C of the peripheral surface portion 32, and has a first through hole 41 that is longer in the circumferential direction than in the radial direction of the support member 12. This allows for a large wall thickness between the outer periphery of the first end face 30 and the outer periphery of the first through hole 41. This allows for a wide solid portion at the outer periphery of the first end face 30, thereby enabling reliable support of the tobacco filler assembly 10. Furthermore, the wide solid portion at the outer periphery of the first end face 30 makes it less likely for the support member 12 to be crushed when held by hand.

[0055] The area of ​​the holes 40 relative to the area of ​​the first end face 30 is calculated as the porosity. The porosity can be set in a range of 50% or less or 75% or more. Preferably, the porosity is set to 35 to 50%. In FIG. 3, the porosity is 34.3%. By making the first through holes 41 elongated in the circumferential direction of the support member 12, the porosity can be ensured to improve the fluidity of the airflow, while a thick solid portion can be formed in the outer periphery to improve the retention of the tobacco filler assembly 10.

[0056] Next, a first modified example of the support member will be described. Fig. 4 shows a perspective view of a support member 13 according to the first modified example. As shown in this figure, the support member 13 has a first end face 30, a second end face 31, and a peripheral surface portion 32, and is formed with a hole 40 that penetrates from the first end face 30 to the second end face 31. The hole 40 has a shape similar to that of the support member 12 shown in Figs. 2 and 3.

[0057] 4 has a large number of uneven portions 45 on the peripheral surface portion 32. The uneven portions 45 have a fine uneven shape along the circumferential direction of the support member 13. The uneven portions 45 are formed over the entire length of the peripheral surface portion 32 of the support member 13 from the first end face 30 to the second end face 31.

[0058] 5 shows a cross-sectional view of a support member 13 according to a first modified example provided in a heated tobacco cartridge 1, taken along a plane perpendicular to the longitudinal direction. As shown in this figure, a number of small gaps are formed by uneven portions 45 between the packaging member 16 wrapped around the outer periphery of the support member 13 and the peripheral surface portion 32 of the support member 13. These gaps are formed so as to continue from the first end face 30 to the second end face 31 of the support member 13, allowing a portion of the airflow to pass from the tobacco filler assembly 10 to the filter 14. This expands the airflow flow path by adding to the holes 40, thereby improving fluidity.

[0059] Furthermore, by forming the uneven portion 45 on the peripheral surface portion 32, the support member 13 can be easily gripped by an assembly machine during the manufacture of the heated tobacco cartridge 1, making the manufacture easier.

[0060] Next, a second modified example of the support member will be described. Fig. 6 shows a front view of a first end face 61 of a support member 60 according to the second modified example. The support member 60 of this example differs from the support member 12 of Fig. 2 in the shape of the hole 63. As shown in Fig. 6, the hole 63 does not include the central axis C of the peripheral surface portion 62, and has a first through hole 64 that is longer in the circumferential direction than in the radial direction.

[0061] The first through-hole 64 has a crescent shape with an elliptical arc S on the side facing the peripheral surface portion 62 of the support member 60 and a straight portion T on the side facing the central axis C of the support member 60. The center position P of the ellipse having the elliptical arc S is located on an imaginary circle V having a certain radius from the central axis C of the peripheral surface portion 62. Three first through-holes 64 are formed along the circumferential direction, and the center positions P of each are all on the imaginary circle V, and are arranged at intervals of 120° from each other.

[0062] The first through hole 64 has an elliptical arc S on the outer periphery side facing the peripheral surface portion 62, making it possible to ensure a sufficient thickness between the outer periphery of the first through hole 64 and the peripheral surface portion 62. In the case of Fig. 3, the entire first through hole 41 is an elliptical arc, whereas in Fig. 6, only a portion of the first through hole 64 is an elliptical arc. It is desirable that the first through hole have an elliptical arc at least within a range of 60° with the center position P of the ellipse as the center.

[0063] Furthermore, the hole portion 63 has a second through hole 65 that includes the central axis C of the peripheral surface portion 62. The second through hole 65 has a circular shape centered on the central axis C. By providing the second through hole 65, the porosity of the support member 60 can be increased.

[0064] Next, a third modified example of the support member will be described. Fig. 7 shows a front view of a first end surface 71 of a support member 70 according to the third modified example. The support member 70 of this example also differs from the support member 12 of Fig. 2 in the shape of the hole 73. As shown in Fig. 7, the hole 73 has a first through hole 74 that does not include the central axis C of the peripheral surface portion 72, and a second through hole 75 that includes the central axis C.

[0065] The first through holes 74 have a circular shape, and four of them are arranged at 90° intervals in the circumferential direction. The second through holes 75 also have a circular shape and are arranged with the central axis C as their center position. In this example, the diameter of the first through holes 74 is made small to ensure the thickness of the outer periphery of the support member 70, while the number of first through holes 74 is increased to ensure the porosity. The porosity in this example is 24.8%.

[0066] Next, a fourth modified example of the support member will be described. Fig. 8 shows a front view of a first end surface 81 of a support member 80 according to the fourth modified example. The support member 80 of this example also differs from the support member 12 of Fig. 2 in the form of the hole 83. As shown in Fig. 8, the hole 83 has a first through hole 84 that does not include the central axis C of the peripheral surface portion 82, and a second through hole 85 that includes the central axis C.

[0067] The first through holes 84 have a circular shape, and five of them are arranged at intervals of 72°. The second through holes 85 also have a circular shape, and are arranged with the central axis C as their center position. In this example, the number of first through holes 84 is further increased to ensure the porosity. In this example, the porosity is 29.7%.

[0068] Next, a fifth modified example of the support member will be described. Fig. 9 shows a front view of a first end surface 91 of a support member 90 according to the fifth modified example. The support member 90 of this example also differs from the support member 12 of Fig. 2 in the shape of the hole portion 93. As shown in Fig. 9, the hole portion 93 has a first through hole 94 that does not include the central axis C of the peripheral surface portion 92, and a second through hole 95 that includes the central axis C.

[0069] The first through holes 94 have an arc shape that is convex toward the outer periphery on the outer periphery side facing the peripheral surface portion 92, and the central axis C side also has an arc shape that is convex toward the outer periphery. The centers of the circles that form the arcs on the outer periphery side of the first through holes 94 are spaced apart at 72° intervals, as in the fourth modified example, and five first through holes 94 are arranged along the circumferential direction. The second through holes 95 have a circular shape and are arranged with the central axis C as their center. The porosity in this example is 27.4%.

[0070] Next, a sixth modified example of the support member will be described. Fig. 10 shows a front view of the first end face 101 of a support member 100 according to the sixth modified example. The support member 100 of this example also differs from the support member 12 of Fig. 2 in the shape of the hole portions 103. As shown in Fig. 10, the hole portions 103 have three first through holes 104 in the circumferential direction that do not include the central axis C of the peripheral surface portion 102. The first through holes 104 have a circular shape, and their centers are arranged at intervals of 120° around the circumferential direction of the first end face 101. The porosity in this example is 34.5%.

[0071] Although the embodiment of the present invention has been described above, the application of the present invention is not limited to this embodiment, and various applications are possible within the scope of the technical concept. For example, in this embodiment, only the support member 12 is provided between the tobacco filler assembly 10 and the filter 14, but a cooling member may be provided between the support member 12 and the filter 14.

[0072] Furthermore, the first through-hole 41, which is longer in the circumferential direction than in the radial direction of the first end face 30, may have a shape other than an elliptical shape.

[0073] Furthermore, as an example of a modification of the support member 12 shown in Figure 2, support member 13 having an uneven portion 45 on the peripheral surface portion 32 is shown, but uneven portions may also be provided on the peripheral surface portion of the support members according to the second to sixth modified examples.

[0074] Fig. 11 shows a cross-sectional view of a heated tobacco cartridge 1001 according to this embodiment. As shown in this figure, the heated tobacco cartridge 1001 is formed by integrating an aerosol-forming substrate 1010 provided at one end, a heated tobacco support member 1012 (hereinafter simply referred to as the support member 1012), and a filter 1014 serving as a mouthpiece, which are arranged along the length direction and wrapped in a sheet-like packaging member 1016. Note that the support member 1012 is shown schematically in Fig. 11. The configuration of the heated tobacco cartridge 1001 according to this embodiment is common to all embodiments, except for the support member 1012.

[0075] The aerosol-forming substrate 1010 is formed into a substantially cylindrical shape by bundling a long tobacco filler 1020 along its length and wrapping it in a sheet-like wrapping material 1025. The tobacco filler 1020 is formed from a non-tobacco plant. However, the tobacco filler 1020 may also be formed from tobacco.

[0076] The tobacco filler 1020 is formed by mixing dried and ground non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, adhesives or thickeners, etc., forming the mixture into a sheet, and then cutting it to a predetermined width and length. However, the tobacco filler 1020 may also be formed into different shapes, such as fine dust or granules.

[0077] The support member 1012 has a flow path 1012c that allows the airflow containing the aerosol generated in the aerosol-forming substrate 1010 to flow toward the filter 1014. A first end surface 1012a of the support member 1012 abuts against the end surface of the aerosol-forming substrate 1010, and a second end surface 1012b of the support member 1012 abuts against the end surface of the filter 1014. The support member 1012 allows the airflow to flow between the aerosol-forming substrate 1010 and the filter 1014, and also supports the aerosol-forming substrate 1010 in the longitudinal direction. The filter 1014 is a sponge-like porous body and is formed in a cylindrical shape.

[0078] In this embodiment, the heated tobacco cartridge 1001 is formed to have a diameter of 6.5 to 7.5 mm and a length of 40 to 49 mm. The aerosol-forming substrate 1010 has a length of 11 to 13 mm. However, it may have other dimensions.

[0079] FIG. 12 shows a cross-sectional view illustrating a usage form of the heated tobacco cartridge 1001. The heated tobacco cartridge 1001 is used by being attached to a heated tobacco body 1002. The heated tobacco body 1002 has an insertion part 1051 into which the heated tobacco cartridge 1001 is inserted. The insertion part 1051 is provided with a needle-shaped or blade-shaped heating part 1050 that is inserted into the tobacco filler 1020 of the inserted heated tobacco cartridge 1001. The heating part 1050 generates heat while inserted into the tobacco filler 1020, thereby generating an aerosol from the tobacco filler 1020. In this state, the user can inhale an airflow containing the aerosol by inhaling through the filter 1014.

[0080] The support member 1012 will be described in detail. The support member 1012 is made of a resin material. An example of the resin material that forms the support member 1012 is silicone. However, the support member 1012 may be made of other resin materials, or materials other than resin materials such as wood or metal (aluminum, etc.) that have a greater cooling effect.

[0081] A support member 1030 according to a first embodiment will now be described. Fig. 13 shows a side view of the support member 1030, and Fig. 14 shows a front view (Fig. 14(a)) and a rear view (Fig. 14(b)) of the support member 1030. The support member 1030 has a first end face 1035 and a second end face 1036 that constitute both end faces along the longitudinal direction of the heated tobacco cartridge 1001. The support member 1030 has a support portion 1031 that is provided at an angle with respect to the central axis C1 of the heated tobacco cartridge 1001 along the longitudinal direction of the heated tobacco cartridge 1001, and lateral extension portions 1032 that extend outward from the support portion 1031. The lateral extension portions 1032 extend from the support portion 1031 in four directions that are mutually orthogonal. The support portion 1031 is inclined relative to the central axis C1 in the Y and Z directions in the figure, but is not inclined in the X direction in the figure. However, the support portion 1031 may be inclined in all of the X, Y, and Z directions in the figure.

[0082] An outer edge 1033 of the lateral extension 1032 contacts the packaging member 1016 of the heated tobacco cartridge 1001, which is shown by the dashed line in Fig. 14. The four regions surrounded by the lateral extension 1032 and the packaging member 1016 each become a flow path 1037 that penetrates from the first end face 1035 to the second end face 1036 of the support member 1030, and allow the airflow containing the aerosol generated from the aerosol-forming substrate 1010 of the heated tobacco cartridge 1001 to flow toward the filter 1014.

[0083] In the support member 1030 of this example, the flow path 1037 is inclined with respect to the central axis C1, which increases the flow distance of the airflow containing the aerosol generated from the aerosol-forming substrate 1010, thereby enhancing the cooling effect of the airflow. In addition, the cross-sectional area of ​​the flow path 1037 changes along the longitudinal direction, which produces turbulence in the airflow and makes it uniform. Furthermore, the outer edge 1033 of the lateral extension portion 1032 that contacts the packaging member 1016 is inclined, which strengthens support for the packaging member 1016 and makes the flow path 1037 less likely to collapse due to external forces from the side.

[0084] A support member 1040 according to a second embodiment will now be described. Fig. 15 shows a front view of the support member 1040, and Fig. 16 shows an enlarged perspective view of the support member 1040 near a support portion 1041. The support member 1040 has four side extensions 1042 whose outer edge portions 1043 contact the packaging member 1016. The side extensions 1042 are arranged so as to extend in four mutually perpendicular directions from the central axis C2 of the support member 1040. The side extensions 1042 are connected by support portions 1041 provided at any position in the longitudinal direction of the support member 1040, and the side extensions 1042 are not directly connected to each other.

[0085] In this example, the support portion 1041 is provided in the center of the support member 1040. The support portion 1041 is formed by connecting rod-shaped members in a cross shape. The lateral extension portion 1042 has a recess 1042a that opens in the direction of the central axis C2 of the support member 1040, and the four ends of the support portion 1041 are respectively disposed in and connected to the recess 1042a. The support portion 1041 is not limited to being rod-shaped, and may have other shapes such as a plate shape.

[0086] In the support member 1040, the four regions surrounded by the lateral extending portions 1042 and the packaging member 1016 form flow paths 1047 through which the airflow containing the aerosol generated from the aerosol-forming substrate 1010 flows. The four lateral extending portions 1042 may each have a different shape. The lateral extending portions 1042 are connected by the support portion 1041 that does not extend in the longitudinal direction, and therefore the shape of each can be designed relatively freely. Furthermore, because the lateral extending portions 1042 are not directly connected to each other, slight gaps are created between the flow paths 1047, and the airflow in each flow path 1047 is made uniform.

[0087] A support member 1060 according to a third embodiment will now be described. Fig. 17 shows an end view of the support member 1060 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1060 has the same cross-sectional shape along the longitudinal direction. Hereinafter, only end views will be shown for support members that have the same cross-sectional shape along the longitudinal direction.

[0088] The support member 1060 has two side extensions 1062 extending radially from a center position C3 (not shown) of the end face shape. The side extensions 1062 form an angle of 180° with each other. Therefore, the two side extensions 1062 are arranged in a straight line. An outer edge 1063 of the side extensions 1062 contacts the packaging member 1016. Two flow paths 1067 are formed by the side extensions 1062 and the packaging member 1016.

[0089] A support member 1070 according to a fourth embodiment, which is a modification of the third embodiment, will now be described. FIG. 18 shows an end view of the support member 1070 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1070 has four lateral extensions 1072 extending radially from a center position C4 (not shown) of the end face shape. The lateral extensions 1072 are at 90° angles to each other. Therefore, the four lateral extensions 1072 form a cross-shaped end face shape. The outer edges 1073 of the lateral extensions 1072 contact the packaging member 1016. The lateral extensions 1072 and the packaging member 1016 form four flow paths 1077.

[0090] As in the support member 1060 according to the third embodiment and the support member 1070 according to the fourth embodiment, by providing a side extension portion extending radially from the center position of the end face shape, the shape of the support member can be simplified and manufacturing can be facilitated. Furthermore, by adjusting the thickness of the side extension portion, it is possible to easily balance the supporting force for the aerosol-forming substrate 1010 and the fluidity of the airflow. Note that the number of side extension portions is not limited to two or four and may be any other number.

[0091] A support member 1080 according to the fifth embodiment will now be described. FIG. 19 shows a perspective view of the support member 1080. The support member 1080 has four side extensions 1082 similar to the support member 1070 according to the fourth embodiment. The support member 1080 is provided with lid portions 1084 at both ends of the side extensions 1082, with outer edge portions 1084a contacting the packaging member 1016. The outer shape of the lid portion 1084 is circular, with the outer edge portion 1084a contacting the packaging member 1016 along the entire circumference. The lid portion 1084 also has communication holes 1084b that communicate with spaces 1086 formed between circumferentially adjacent side extensions 1082. Since four spaces 1086 are formed in the circumferential direction, four communication holes 1084b are also formed. Since the support member 1080 has the lid portion 1084, the area of ​​the end face that comes into contact with the aerosol-forming substrate 1010 can be increased, and the aerosol-forming substrate 1010 can be supported more firmly.

[0092] The support members according to the first to fourth embodiments may have a connecting portion that connects at least two circumferentially adjacent lateral extension portions together in the circumferential direction. The connecting portion may be formed around the entire circumference of the support member, or may be formed around a portion of the circumference of the support member. A support member 1090 according to a sixth embodiment shown in FIG. 20 is the support member 1060 according to the third embodiment, to which a connecting portion 1093 is provided. The support member 1090 has two lateral extension portions 1092 that extend radially from the central axis C1 of the heated tobacco cartridge 1001, and outer edge portions 1921 of the lateral extension portions 1092 contact the packaging member 1016. The lateral extension portions 1092 are connected by a connecting portion 1093 that has an arc-shaped cross section. An outer peripheral surface 1093a of the connecting portion 1093 contacts the packaging member 1016. As a result, the connecting portion 1093 is present at the periphery of the support member 1090, and therefore the support function of the aerosol-forming substrate 1010 can be improved.

[0093] A support member 1100 according to a seventh embodiment will now be described. FIG. 21 shows an end view of the support member 1100 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1100 has a support portion 1101 with a circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, and an outer peripheral portion 1002 with a circular cross section that is disposed outside the support portion 1101. In this specification, the term "along the central axis" broadly includes a mode of extending in the direction of the central axis C1 of the heated tobacco cartridge 1001. Specifically, in addition to a mode of extending linearly in the direction of the central axis C1, it also includes a mode of extending in a curved shape, a mode of extending in a wave shape, a mode of extending in a spiral shape, or a combination of these. The outer peripheral portion 1002 is connected to the outer edge of the support portion 1101 by a connecting portion 1104. An outer edge 1103 of the outer peripheral portion 1002 contacts the packaging material 1016. The support portion 1101 and the outer peripheral portion 1102 are arranged concentrically, and the connecting portion 1104 is arranged along the radial direction. The support portion 1101 has a through-hole portion 1106 in the center.

[0094] An outer edge 1103 of the outer periphery 1102 contacts the packaging member 1016, but since the outer edge 1103 is provided around the entire periphery, there is almost no gap between the support member 1100 and the packaging member 1016. In the support member 1100, a flow path 1107 is formed between the support part 1101 and the outer periphery 1102. In addition, the through-holes 1106 of the support part 1101 also serve as flow paths for the airflow.

[0095] In this way, the support member 1100 has the support portion 1101 and the outer peripheral portion 1102, and therefore the support member 1100 supports both the radial support portion and the peripheral portion of the aerosol-forming substrate 1010. This effectively prevents the aerosol-forming substrate 1010 from falling off. Note that the support portion 1101 does not necessarily have to have the through-hole portion 1106.

[0096] A support member 1110 according to an eighth embodiment, which is a modified example of the seventh embodiment, will now be described. FIG. 22 shows an end view of the support member 1110 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1110 has a support portion 1111 with a circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, and four plate-shaped outer peripheral portions 1112 that are connected to the outer edge of the support portion 1111. Through-holes 1116 are formed in the support portion 1111. The outer peripheral portions 1112 are each arranged at an angle of 90° in the circumferential direction and extend radially. An outer edge portion 1113 of the outer peripheral portion 1112 contacts the packaging member 1016.

[0097] In the support member 1110, four flow paths 1117 are formed in the circumferential direction by the support portion 1111, the outer circumferential portion 1112, and the packaging member 1016. Furthermore, the through-hole portions 1116 of the support portion 1111 also serve as flow paths for the airflow. In this manner, the outer circumferential portion 1112 may be formed in a plate shape, and the flow paths 1117 may be formed between the outer circumferential portion 1112 and the packaging member 1016. Note that the support portion 1111 does not necessarily have to have the through-hole portions 1116.

[0098] A support member 1120 according to a ninth embodiment, which is a modified example of the seventh embodiment, will be described. FIG. 23 shows an end view of the support member 1120 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1120 has a support portion 1121 with a circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, and four outer peripheral portions 1122 connected to the outer edge of the support portion 1121. A through-hole portion 1126 is formed in the support portion 1121. The outer peripheral portions 1122 have a fan-shaped cross section that widens from the center toward the outer peripheral portion. The outer peripheral portions 1122 are arranged at angles of 90° in the circumferential direction. An outer edge portion 1123 of the outer peripheral portion 1122 contacts the packaging member 1016.

[0099] In the support member 1120, four flow paths 1127 are formed in the circumferential direction by the support part 1121, the outer circumferential part 1122, and the packaging member 1016. In addition, the through-hole parts 1126 of the support part 1121 also serve as flow paths for the airflow. By making the outer circumferential part 1122 fan-shaped in this way, the area for supporting the aerosol-forming substrate 1010 is increased. Note that the support part 1121 does not necessarily have to have the through-hole parts 1126.

[0100] A support member 1130 according to a tenth embodiment, which is a modification of the embodiment in Fig. 17, will now be described. Fig. 24 shows an end view of the support member 1130 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1130 has a support portion 1131 with a square cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, and four plate-like outer peripheral portions 1132 that are connected to the outer edge of the support portion 1131. A through-hole portion 1136 is formed in the support portion 1131. The outer peripheral portions 1132 extend radially from the corners of the support portion 1131. An outer edge portion 1133 of the outer peripheral portion 1132 contacts the packaging member 1016.

[0101] In the support member 1130, four flow paths 1137 are formed in the circumferential direction by the support portion 1131, the outer peripheral portion 1132, and the packaging member 1016. Furthermore, the through-holes 1136 of the support portion 1131 also serve as flow paths for the airflow. In this manner, the support portion 1131 can take various forms, such as a square cross section. Note that the support portion 1131 does not necessarily have to have the through-holes 1136.

[0102] A support member 1140 according to an eleventh embodiment will now be described. FIG. 25 shows a perspective view of the support member 1140. The support member 1140 has a support portion 1141 with a circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, and a lateral extension portion 1142 that extends outward from the support portion 1141. The support portion 1141 has a through-hole portion 1146. The lateral extension portion 1142 is formed in a spiral shape along the longitudinal direction of the support portion 1141. An outer edge portion 1143 of the lateral extension portion 1142 contacts the packaging member 1016. Therefore, the area surrounded by the support portion 1141, the lateral extension portion 1142, and the packaging member 1016 becomes the airflow path. Because the lateral extension portion 1142 is spiral-shaped, the airflow path is longer, thereby enhancing the cooling effect of the airflow. Furthermore, since outer edge portion 1143 in contact with packaging member 1016 extends in the circumferential and longitudinal directions, the flow path is less likely to be crushed by an external force from the side. Note that support portion 1141 does not necessarily have to have through-hole portion 1146.

[0103] A support member 1150 according to a twelfth embodiment will now be described. Fig. 26 shows a side view of the support member 1150, and Fig. 27 shows a front view of the support member 1150. The support member 1150 has a support portion 1151 with a circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001, a lateral extension portion 1152 that extends outward from the support portion 1151, and a second lateral extension portion 1158 that extends from the lateral extension portion 1152.

[0104] The lateral extending portion 1152 is formed in a plate shape extending radially from the central portion 1151. An outer edge portion 1153 of the lateral extending portion 1152 contacts the packaging member 1016. The lateral extending portion 1152 is longer in the longitudinal direction than the central portion 1151, and a connecting portion 1154 is provided on the lateral extending portion 1152 on the tip side of the end face of the central portion 1151, extending along the radial direction of the central portion 1151. One end of the connecting portion 1154 is connected to the lateral extending portion 1152, and the other end of the connecting portion 1154 is connected to the second lateral extending portion 1158.

[0105] The second lateral extension 1158 is a plate-shaped member extending radially from the central portion 1151. The second lateral extension 1158 is connected only to the lateral extension 1152 by the connecting portion 1154, and a gap is formed between the second lateral extension 1158 and the central portion 1151. An outer edge 1159 of the second lateral extension 1158 contacts the packaging member 1016. The area surrounded by the central portion 1151, the lateral extension 1152, the second lateral extension 1158, and the packaging member 1016 forms an airflow flow path 1157. In this example, there is only one second lateral extension 1158; however, by changing the shape of the connecting portion 1154, two or more second lateral extensions 1158 can be provided in the circumferential direction. Because the second lateral extension 1158 is connected only to the lateral extension 1152 via the connecting portion 1154, the number of second lateral extensions 1158 can be easily changed as needed.

[0106] A support member 1160 according to a thirteenth embodiment will now be described. Fig. 28 shows an end view of the support member 1160 cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge 1001. The support member 1160 has a main body 1161 with a generally circular cross section that is provided along the central axis C1 of the heated tobacco cartridge 1001. An outer edge 1163, which is the outer peripheral surface of the main body 1161, contacts the packaging member 1016. The main body 1161 has a notch 1162 formed by cutting out a portion of the outer edge 1163. The main body 1161 also has a through-hole 1166 in its center.

[0107] The notch 1162 is in the form of a narrow groove, and the bottom has an arc-shaped cross section. The notch 1162 serves as a flow path for the airflow. The through-hole 1166 also serves as a flow path for the airflow. The balance between the support function of the aerosol-forming substrate 1010 and the fluidity of the airflow can be adjusted by the shape and number of the notch 1162 and the presence or absence, shape, and number of the through-hole 1166. Below, a modified example having a notch will be described.

[0108] The support member 1170 in Fig. 29(a) has two notches 1172 that are arranged at an angle of 180° from each other. The support member 1180 in Fig. 29(b) has two notches 1182 that are arranged at an angle of approximately 45° from each other. The support member 1190 in Fig. 29(c) has two notches 1192 with a straight cross-section at the bottom, and has a through-hole 1196.

[0109] Support member 1200 in Fig. 30(a) has one slightly wide cutout 1202. Support member 1210 in Fig. 30(b) has a slightly wide cutout 1212 and a through-hole 1216 in the center. Support member 1220 in Fig. 30(c) has two cutouts 1222, and through-hole 1226 has an elliptical cross-section. Support member 1230 in Fig. 30(d) has three cutouts 1232 and two through-holes 1236.

[0110] A support member 1240 in Fig. 31(a) has a cutout portion 1242 having a substantially triangular groove-shaped cross section. A support member 1250 in Fig. 31(b) has a cutout portion 1252 having a substantially triangular groove-shaped cross section and a through-hole portion 1256. A support member 1260 in Fig. 31(c) has two cutout portions 1262 having a substantially triangular groove-shaped cross section and a through-hole portion 1266. A support member 1270 in Fig. 31(d) has four cutout portions 1272 having a substantially triangular groove-shaped cross section.

[0111] A support member 1280 in FIG. 32(a) has a number of notches 1282, each having a substantially triangular groove cross section and smaller than the notch 1242 in FIG. 31(a), all around the circumference. A support member 1290 in FIG. 32(b) has a number of notches 1292, each having a substantially triangular groove cross section, all around the circumference, and has a through-hole 1296 in the center. A support member 1300 in FIG. 32(c) has a number of notches 1302, each having a substantially triangular groove cross section, in a partial region in the circumferential direction, and has two through-holes 1306. A support member 1310 in FIG. 32(d) has a number of notches 1312, each having a substantially triangular groove cross section, in a partial region in the circumferential direction.

[0112] A support member 1320 in FIG. 33(a) has a number of notches 1322 formed by smoothly curved grooves all around the circumference. A support member 1330 in FIG. 33(b) has a number of notches 1332 formed by smoothly curved grooves all around the circumference, and also has a through-hole 1336 in the center. A support member 1340 in FIG. 33(c) has a number of notches 1342 formed by smoothly curved grooves in a portion of the circumference, and also has two through-holes 1346. A support member 1350 in FIG. 33(d) has a number of notches 1352 formed by smoothly curved grooves in a portion of the circumference, and also has three through-holes 1356.

[0113] A support member 1360 in FIG. 34(a) has a number of cutouts 1362 with a substantially square cross section all around the circumference. A support member 1370 in FIG. 34(b) has a number of cutouts 1372 with a substantially square cross section all around the circumference, and has a through-hole 1376 in the center. A support member 1380 in FIG. 34(c) has a number of cutouts 1382 with a substantially square cross section at a portion of the circumference, and has three through-holes 1386. A support member 1390 in FIG. 34(d) has a number of cutouts 1392a with a substantially square cross section, a cutout 1392b with a substantially triangular cross section, and a cutout 1392c formed with a smoothly curved surface, each at different positions in the circumference.

[0114] As described above, the support member having a cutout can take various forms. In each case, the gap between the cutout and the packaging member 1016 can serve as a flow path for the airflow. In each embodiment having a cutout, the area of ​​the solid portion of the support member is increased, thereby improving the support function of the aerosol-forming substrate 1010.

[0115] A support member 1400 according to a fourteenth embodiment will now be described. Fig. 35 shows an end view of the support member 1400 according to the fourteenth embodiment, cut along a plane perpendicular to the central axis C1 of the heated tobacco cartridge. The support member 1400 has five through-holes 1406 in the central and peripheral portions.

[0116] The support member 1400 can adjust the fluidity of the airflow from the aerosol-forming substrate 1010 by adjusting the porosity, which is the ratio of the cross-sectional area of ​​the through-holes 1406 to the cross-sectional area of ​​the support member 1400. In addition, the airflow resistance can be adjusted by the thickness and material of the packaging member 1016. Because there is a slight gap between the packaging member 1016 and the support member 1400, when the filter 1014 is sucked and the inside of the packaging member 1016 becomes negative pressure, external air is taken in through the packaging member 1016. The degree to which external air is taken in varies depending on the airflow resistance of the packaging member 1016.

[0117] When the airflow resistance of the packaging member 1016 is less than 30 kPa, the low airflow resistance allows outside air to be easily taken in, and a mild taste can be obtained in combination with the airflow from the aerosol-forming substrate 1010. In this case, the porosity of the support member 1400 is preferably less than 50%.

[0118] When the airflow resistance of the packaging member 1016 is 30 kPa or more and less than 70 kPa, the airflow resistance is in the medium range, and by taking in a moderate amount of outside air, a good balance can be achieved with the airflow from the aerosol-forming substrate 1010. In this case, the porosity of the support member 1400 is preferably 30 to 70%.

[0119] If the airflow resistance of the packaging member 1016 is 70 kPa or more, the high airflow resistance makes it difficult for outside air to be taken in, and the airflow from the aerosol-forming substrate 1010 becomes dominant, resulting in a strong, satisfying taste. In this case, the porosity of the support member 1400 is preferably 50% or more.

[0120] When the porosity (%) of the support member 1400 is A and the airflow resistance (kPa) of the packaging member 1016 is B, it is desirable that one of the following relational expressions (1) to (4) be satisfied. A×B=1050~10500 (1) A2×B=5000~25000 (2) A3×B=160,000~400,000 (3) A4×B=5,000,000~6,500,000 (4)

[0121] Although the embodiments of the present invention have been described above, the application of the present invention is not limited to these embodiments and can be applied in various ways within the scope of its technical concept. For example, in this embodiment, only the support member 1012 is provided between the aerosol-forming substrate 1010 and the mouthpiece 1014, but another member such as a cooling member may be provided between the support member 1012 and the mouthpiece 1014. Furthermore, the number of lateral extension portions in each example may be one or more. [Explanation of symbols]
