TECHNICAL FIELD The present invention relates to a heated tobacco support member used in a heated tobacco having a tobacco filler made of tobacco or non-tobacco plants, and a heated tobacco cartridge having the same.

In recent years, in line with the trend towards quitting smoking, heat-not-burn tobacco products have become popular, allowing users to enjoy tobacco by heating a cartridge containing tobacco ingredients and inhaling the vaporized tobacco ingredients without using a flame. It's starting to happen. A heated tobacco cartridge includes a tobacco filling that is heated by inserting a heating element such as a blade of the heating tobacco main body, a filter provided in the mouthpiece, and a support member provided between the tobacco filling and the filter. It is formed by wrapping these with a packaging material such as paper. Examples of such heated tobacco support members and heated tobacco cartridges include those listed in Patent Document 1.

Furthermore, in the heated tobacco disclosed in 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 to generate an aerosol containing tobacco components. The heated tobacco cartridge has a hollow tubular support member that supports an aerosol-forming substrate and resists forces experienced by the cartridge when a heating element is inserted into the aerosol-forming substrate. The tobacco components released from the aerosol-forming substrate upon heating are transferred through the hollow portion of the support member to the mouthpiece located downstream and inhaled by the user.

Embodiments 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 according to the present embodiment. As shown in this figure, the heated tobacco cartridge 1 includes a substantially cylindrical tobacco filler assembly 10 filled with a large number of tobacco fillers 20, and a heated tobacco support member 12 (hereinafter simply referred to as the support member 12). ) and a filter 14 serving as a suction port are arranged along the length direction and are integrally formed by being wrapped with a sheet-like packaging member 16.

The tobacco filler assembly 10 is formed into a substantially cylindrical shape by bundling long tobacco fillers 20 along the length direction and wrapping them with a sheet-like packaging body 25. . Tobacco filler 20 is formed from non-tobacco plants. However, the tobacco filler 20 may also be formed of tobacco.

The tobacco filling 20 is made by mixing dried and crushed non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, flavor additives, preservatives, adhesives, thickeners, etc. It is formed by molding it into a shape and then cutting it to have a predetermined width and length. However, the tobacco filling 20 may also be formed in the form of dust.

The support member 12 allows the airflow containing the aerosol generated in the tobacco filler assembly 10 to flow toward the filter 14 side. A first end surface 30 of the support member 12 abuts an end surface of the tobacco filler stack 10 , and a second end surface 31 of the support member 12 abuts an end surface of the filter 14 . The support member 12 has a hole 40 extending from the first end surface 30 to the second end surface 31, and airflow flows through the hole 40. The filter 14 is a sponge-like porous body and is formed in a cylindrical shape.

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. Further, the tobacco filling assembly 10 has a length of 11 to 13 mm. However, it may have dimensions other than this.

FIG. 2 shows a cross-sectional view showing how the heated tobacco cartridge 1 is used. The heated tobacco cartridge 1 is used by being attached to a heated tobacco main body 2. The heated tobacco main body 2 has an insertion portion 51 into which the heated tobacco cartridge 1 is inserted. The insertion portion 51 is provided with a needle-shaped or blade-shaped heating portion 50 that is inserted into the tobacco filling 20 of the inserted heated tobacco cartridge 1 . The heating unit 50 can generate aerosol from the tobacco filling 20 by generating heat while inserted into the tobacco filling 20. In this state, the user can inhale airflow containing aerosol by inhaling through the filter 14.

The support member 12 will be explained in detail. FIG. 3 shows a perspective view of the support member 12. The support member 12 is a cylindrical member made of resin material. Examples of the resin material forming the support member 12 include silicone. However, the support member 12 may be formed of a resin material other than this, or a material other than the resin material, such as wood or metal (aluminum, etc.) that increases the cooling effect.

As shown in FIG. 3, the support member 12 has a first end surface 30, a second end surface 31, and a peripheral surface portion 32. The support member 12 has a hole 40 penetrating from the first end surface 30 to the second end surface 31. The hole portion 40 functions as a flow path through which an airflow containing aerosol generated in the tobacco filler assembly 10 flows to the filter 14 side.

FIG. 4 is a diagram showing the first end surface 30 of the support member 12 as the front. The support member 12 has the same shape from the first end surface 30 to the second end surface 31 in a cross-sectional shape cut along a plane perpendicular to the length direction. Therefore, the cross-sectional shape is also the same as that in FIG. 4 .

As shown in FIG. 4, the hole portion 40 has a first through hole 41 arranged at the outer peripheral portion so as not to include the central axis C of the peripheral surface portion 32. As shown in FIG. The first through hole 41 has an elliptical shape and is 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 elliptical centers P of the first through holes 41 are each arranged on a virtual circle V having a constant radius from the central axis C. Further, the ellipse centers P are arranged at intervals of 120° in the circumferential direction with the center axis C as the center. Therefore, the three first through holes 41 are arranged at equal intervals in the circumferential direction.

The first end surface 30 has a void in the hole 40 portion and is solid in the other portion, and this solid portion abuts the end surface of the tobacco filler aggregate 10. Since the tobacco filler stack 10 receives force in the longitudinal direction when the heating part 50 of the heated tobacco main body 2 is inserted, the tobacco filler stack 10 is pushed by the solid portion of the supporting member 12 that comes into contact with the tobacco filler stack 10. can be supported. The hole 40 of this embodiment is arranged at the outer peripheral part of the support member 12 so as not to include the central axis C of the peripheral surface part 32, and the first through hole 41 has a shape that is longer in the circumferential direction than in the radial direction of the support member 12. Therefore, the wall thickness between the outer peripheral end of the first end surface 30 and the outer peripheral end of the first through hole 41 can be increased. Therefore, the solid portion of the outer peripheral portion of the first end surface 30 can be made wider, so that the tobacco filler assembly 10 can be supported reliably. Further, since the solid portion of the outer peripheral portion of the first end surface 30 is wide, the shape of the support member 12 can be prevented from being easily crushed when the support member 12 is held by hand.

The area of the hole 40 relative to the area of the first end surface 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 35-50%. In FIG. 4, the porosity is 34.3%. By making the first through hole 41 long in the circumferential direction of the support member 12, the porosity is ensured to improve the fluidity of airflow, and a thick solid part is formed on the outer periphery to accumulate tobacco filling. The retainability of the body 10 can also be improved.

Next, a first modified example of the support member will be described. FIG. 5 shows a perspective view of the support member 13 according to the first modification. As shown in this figure, the support member 13 has a first end surface 30, a second end surface 31, and a peripheral surface portion 32, and a hole portion 40 penetrating between the first end surface 30 and the second end surface 31 is formed. There is. The hole 40 has a similar shape to the support member 12 shown in FIGS. 3 and 4.

The support member 13 in FIG. 5 has a large number of uneven portions 45 on the peripheral surface portion 32. As shown in FIG. The uneven portion 45 has a fine uneven shape along the circumferential direction of the support member 13. Further, the uneven portion 45 is formed to span the entire length of the peripheral surface portion 32 of the support member 13 from the first end surface 30 to the second end surface 31.

FIG. 6 shows a cross-sectional view of the support member 13 according to the first modification provided in the heated tobacco cartridge 1, taken along a plane perpendicular to the length direction. As shown in this figure, a large number of small voids are formed by the uneven portions 45 between the packaging member 16 wound around the outer periphery of the support member 13 and the peripheral surface portion 32 of the support member 13. Since this gap is formed so as to be continuous from the first end surface 30 to the second end surface 31 of the support member 13, a portion of the airflow from the tobacco filler assembly 10 to the filter 14 can flow therethrough. Thereby, the air flow path can be expanded in addition to the hole 40, and fluidity can be improved.

Further, by forming the uneven portion 45 on the peripheral surface portion 32, the supporting member 13 can be easily held by an assembly machine when manufacturing the heated tobacco cartridge 1, and manufacturing can be facilitated. can.

Three first through holes 64 are formed along the circumferential direction, and the center positions P of each are located on the virtual circle V, and are spaced apart from each other by 120°.

Since the first through hole 64 has an elliptical arc S on the outer periphery side facing the peripheral surface portion 62, a sufficient wall thickness can be ensured between the outer periphery of the first through hole 64 and the peripheral surface portion 62. . In the case of FIG. 4, the entire first through hole 41 is an elliptical arc, whereas in FIG. 7, a part of the first through hole 64 is an elliptical arc. It is desirable that the first through hole has an elliptical arc within a range of at least 60 degrees around the center position P of the ellipse.

Further, 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.

Tobacco filler 1020 is formed from non-tobacco plants. However, tobacco filler 1020 may also be formed of tobacco.

Tobacco filling 1020 is made by mixing dried and crushed non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, adhesives, thickeners, etc. It is formed by molding it into a shape and then cutting it to have a predetermined width and length. However, the tobacco filler 1020 may be formed into a different shape, such as fine dust or granules.

The support member 1012 has a flow path 1012c that allows airflow containing the aerosol generated in the aerosol forming base material 1010 to flow toward the filter 1014 side. The first end surface 1012a of the support member 1012 contacts the end surface of the aerosol forming base material 1010, and the second end surface 1012b of the support member 1012 contacts the end surface of the filter 1014. The support member 1012 allows airflow to flow between the aerosol-forming base material 1010 and the filter 1014, and supports the aerosol-forming base material 1010 in the length direction. Filter 1014 is a sponge-like porous body and is formed in a cylindrical shape.

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. Further, the aerosol forming substrate 1010 has a length of 11 to 13 mm. However, it may have dimensions other than this.

FIG. 13 shows a cross-sectional view showing how the heated tobacco cartridge 1001 is used. The heated tobacco cartridge 1001 is used by being attached to the heated tobacco main body 1002. The heated tobacco main body 1002 has an insertion portion 1051 into which the heated tobacco cartridge 1001 is inserted. The insertion portion 1051 is provided with a needle-shaped or blade-shaped heating portion 1050 that is inserted into the tobacco filling 1020 of the inserted heated tobacco cartridge 1001. The heating unit 1050 can generate aerosol from the tobacco filling 1020 by generating heat while inserted into the tobacco filling 1020. In this state, the user can inhale airflow containing aerosol by inhaling through the filter 1014.

The support member 1012 will be explained in detail. Support member 1012 is made of resin material. Examples of the resin material forming the support member 1012 include silicone. However, the support member 1012 may be made of a resin material other than this, or a material other than the resin material, such as wood or metal (aluminum, etc.) that increases the cooling effect.

The support member 1030 according to the first example will be explained. FIG. 14 shows a side view of the support member 1030, and FIG. 15 shows a front view of the support member 1030 (FIG. 15(a)) and a rear view of the support member 1030 (FIG. 15(b)). The support member 1030 has a first end surface 1035 and a second end surface 1036 that constitute both end surfaces along the longitudinal direction of the heated tobacco cartridge 1001. The support member 1030 includes a support portion 1031 provided along the longitudinal direction of the heated tobacco cartridge 1001 at an angle with respect to the central axis C1 of the heated tobacco cartridge 1001, and a side portion extending outward from the support portion 1031. It has an extending portion 1032. The lateral extension portions 1032 extend from the support portion 1031 in four directions orthogonal to each other. The support portion 1031 is inclined along the Y direction and the Z direction in the figure with respect to the central axis C1, and 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.

An outer edge 1033 of the lateral extension 1032 contacts the packaging member 1016 of the heated tobacco cartridge 1001, which is shown by a dashed line in FIG. The four areas surrounded by the lateral extensions 1032 and the packaging member 1016 serve as channels 1037 that penetrate from the first end surface 1035 to the second end surface 1036 of the support member 1030, and serve as a flow path 1037 for forming an aerosol forming base of the heated tobacco cartridge 1001. Airflow containing aerosol generated from the material 1010 can be made to flow toward the filter 1014 side.

In the support member 1030 of this example, since the flow path 1037 is inclined with respect to the central axis C1, the flow distance of the airflow containing the aerosol generated from the aerosol forming base material 1010 is increased, and the cooling effect of the airflow is enhanced. be able to. Further, since the cross-sectional area of the flow path 1037 changes along the longitudinal direction, turbulence is generated in the airflow, which has the effect of making it uniform. Furthermore, since the outer edge portion 1033 of the lateral extension portion 1032 in contact with the packaging member 1016 is sloped, the packaging member 1016 is strongly supported and the channel 1037 is prevented from being crushed by external force from the side. be able to.

A support member 1040 according to a second example will be explained. FIG. 16 shows a front view of the support member 1040, and FIG. 17 shows an enlarged perspective view of the vicinity of the support portion 1041 of the support member 1040. The support member 1040 has four lateral extensions 1042 whose outer edges 1043 are in contact with the packaging member 1016. The lateral extensions 1042 are arranged to extend in four directions perpendicular to each other from the central axis C2 of the support member 1040. The lateral extensions 1042 are connected by a support 1041 provided at an arbitrary position in the longitudinal direction of the support member 1040, and the lateral extensions 1042 are not directly connected to each other.

The support portion 1041 is provided at the center of the support member 1040 in this example. The support portion 1041 is formed by connecting rod-shaped members in a cross shape. The lateral extension 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 1041 are respectively arranged and connected to the recess 1042a. The support portion 1041 is not limited to a rod shape, and may have other shapes such as a plate shape.

In the support member 1040 as well, the four regions surrounded by the lateral extensions 1042 and the packaging member 1016 serve as channels 1047 through which the airflow containing the aerosol generated from the aerosol forming base material 1010 flows. The four lateral extensions 1042 may each have a different configuration. Since the lateral extension parts 1042 are connected by the support part 1041 that does not extend in the longitudinal direction, the shape of each part can be designed relatively freely. Further, since the side extending portions 1042 are not directly connected to each other, a slight gap is created between the flow channels 1047, and the airflow in each flow channel 1047 is made uniform.

A support member 1060 according to a third example will be explained. FIG. 18 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 of support members having the same cross-sectional shape along the longitudinal direction are shown.

The support member 1060 has two lateral extensions 1062 extending in the radial direction from a center position C3 (not shown) of the end face shape. The lateral extensions 1062 are at an angle of 180° with respect to each other. Therefore, the two lateral extensions 1062 are arranged in a straight line. An outer edge 1063 of the lateral extension 1062 contacts the packaging member 1016. Two channels 1067 are formed by the lateral extension 1062 and the packaging member 1016.

A support member 1070 according to a fourth example, which is a modification of the third example, will be described. FIG. 19 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 in the radial direction from a center position C4 (not shown) of the end face shape. The lateral extensions 1072 are at a 90° angle with respect to each other. Therefore, the four lateral extensions 1072 form a cross-shaped end face shape. An outer edge 1073 of the lateral extension 1072 contacts the packaging member 1016. Four channels 1077 are formed by the lateral extensions 1072 and the packaging member 1016.

Like the support member 1060 according to the third embodiment and the support member 1070 according to the fourth embodiment, the shape of the support member can be changed by having a lateral extending portion along the radial direction from the center position of the end face shape. It can be made simple and easy to manufacture. Further, by adjusting the wall thickness of the side extending portion, it is possible to easily balance the supporting force for the aerosol forming base material 1010 and the fluidity of the airflow. Note that the number of lateral extensions is not limited to two or four, and may be any other number.

A support member 1080 according to a fifth example will be explained. FIG. 20 shows a perspective view of the support member 1080. The support member 1080 has four lateral 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 lateral extension portion 1082, the outer edge portions 1084a of which are in contact with the packaging member 1016. The outer shape of the lid part 1084 has a circular shape in which the outer edge part 1084a is in contact with the packaging member 1016 over the entire circumference. Further, the lid portion 1084 has a communication hole portion 1084b that communicates with a space portion 1086 formed between circumferentially adjacent side extension portions 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 surface in contact with the aerosol-forming base material 1010 can be increased, and the aerosol-forming base material 1010 can be supported more firmly.

The support members according to the first to fourth embodiments may have a connecting portion that connects at least two circumferentially adjacent side extending portions to each other in the circumferential direction. The connecting portion may be formed over the entire circumference of the support member, or may be formed over a portion of the support member in the circumferential direction. A support member 1090 according to the sixth embodiment shown in FIG. 21 is obtained by providing a connecting portion 1093 in the support member 1060 according to the third embodiment. The support member 1090 has two lateral extensions 1092 extending in the radial direction from the central axis C1 of the heated tobacco cartridge 1001, and an outer edge 1921 of the lateral extensions 1092 contacts the packaging member 1016. The lateral extending portions 1092 are connected by a connecting portion 1093 having an arcuate cross section. An outer circumferential surface 1093a of the connecting portion 1093 contacts the packaging member 1016. Accordingly, since the connecting portion 1093 is present at the peripheral edge of the support member 1090, the support function of the aerosol forming base material 1010 can be enhanced.

A support member 1100 according to a seventh example will be explained. FIG. 22 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 part 1101 with a circular cross section provided along the central axis C1 of the heated tobacco cartridge 1001, and an outer peripheral part 1002 with a circular cross section located outside the support part 1101. .

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 at the center.

The outer edge portion 1103 of the outer circumferential portion 1102 contacts the packaging member 1016, but since the outer edge portion 1103 is provided over the entire circumference, 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 portion 1101 and the outer peripheral portion 1102. Furthermore, the through hole portion 1106 of the support portion 1101 also serves as a flow path for airflow.

In this way, since the support member 1100 has the support part 1101 and the outer peripheral part 1102, the support member 1100 supports both the radial support part and the peripheral part of the aerosol forming base material 1010. Thereby, falling off of the aerosol forming base material 1010 can be effectively prevented. Note that the support portion 1101 does not need to have the through hole portion 1106.

In the support member 1110, four channels 1117 are formed in the circumferential direction by the support portion 1111, the outer peripheral portion 1112, and the packaging member 1016. Furthermore, the through hole portion 1116 of the support portion 1111 also serves as a flow path for airflow. In this way, the outer peripheral portion 1112 may be formed into a plate shape, and the flow path 1117 may be formed between it and the packaging member 1016. Note that the support portion 1111 does not need to have the through hole portion 1116.

A through hole portion 1126 is formed in the support portion 1121 . The outer peripheral portion 1122 has a fan-shaped cross-sectional shape that widens from the center side toward the outer peripheral side. The outer peripheral portions 1122 are each arranged at an angle of 90° in the circumferential direction. An outer edge portion 1123 of the outer peripheral portion 1122 contacts the packaging member 1016.

In the support member 1120, four channels 1127 are formed in the circumferential direction by the support portion 1121, the outer peripheral portion 1122, and the packaging member 1016. Furthermore, the through hole portion 1126 of the support portion 1121 also serves as a flow path for airflow. By making the outer peripheral portion 1122 fan-shaped in this way, the area for supporting the aerosol forming base material 1010 becomes larger. Note that the support portion 1121 does not need to have the through hole portion 1126.

A support member 1130 according to a tenth example, which is a modification of the example shown in FIG. 18, will be described. FIG. 25 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 part 1131 with a rectangular cross section provided along the central axis C1 of the heated tobacco cartridge 1001, and four plate-shaped outer peripheral parts 1132 connected to the outer edge of the support part 1131. There is. A through hole portion 1136 is formed in the support portion 1131 . The outer peripheral portion 1132 extends from the corner of the support portion 1131 along the radial direction. An outer edge portion 1133 of the outer peripheral portion 1132 contacts the packaging member 1016.

In the support member 1130, four channels 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 hole portion 1136 of the support portion 1131 also serves as a flow path for airflow. In this way, the support portion 1131 can take various shapes such as a rectangular cross section. Note that the support portion 1131 does not need to have the through hole portion 1136.

A support member 1140 according to an eleventh example will be explained. FIG. 26 shows a perspective view of the support member 1140. The support member 1140 has a support portion 1141 having a circular cross section and provided along the central axis C1 of the heated tobacco cartridge 1001, and a lateral extension portion 1142 extending outward from the support portion 1141. The support portion 1141 has a through hole portion 1146. The lateral extension part 1142 is formed in a spiral shape along the longitudinal direction of the support part 1141. An outer edge 1143 of the lateral extension 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 an air flow path. Since the side extending portion 1142 has a spiral shape, the airflow path becomes long, and the cooling effect of the airflow can be enhanced. Further, since the outer edge portion 1143 in contact with the packaging member 1016 extends in the circumferential direction and the longitudinal direction, the flow path can be made less likely to be crushed by external force from the side. Note that the support portion 1141 does not need to have the through hole portion 1146.

A support member 1150 according to a twelfth example will be explained. FIG. 27 shows a side view of the support member 1150, and FIG. 28 shows a front view of the support member 1150.

The lateral extending portion 1152 is formed in a plate shape extending from the center portion 1151 in the radial direction. An outer edge 1153 of the lateral extension 1152 contacts the packaging member 1016. The lateral extending portion 1152 is longer than the center portion 1151 in the longitudinal direction, and a connecting portion 1154 extending in the radial direction of the center portion 1151 is provided on the distal end side of the end surface of the center portion 1151 in the lateral extending portion 1152. A lateral extending portion 1152 is connected to one end of the connecting portion 1154, and a second lateral extending portion 1158 is connected to the other end of the connecting portion 1154.

The second lateral extending portion 1158 is a plate-shaped member extending in the radial direction of the center portion 1151, and is connected only to the lateral extending portion 1152 at a connecting portion 1154, with a gap between the second lateral extending portion 1158 and the center portion 1151. has. An outer edge 1159 of the second lateral extension 1158 contacts the packaging member 1016. A region surrounded by the center portion 1151, the lateral extensions 1152, the second lateral extensions 1158, and the packaging member 1016 becomes an air flow path 1157. In this example, there is one second lateral extending portion 1158, but by changing the shape of the connecting portion 1154, two or more second lateral extending portions 1158 can be provided in the circumferential direction. Since the second lateral extending portions 1158 are connected only to the lateral extending portions 1152 via the connecting portions 1154, the number of the second lateral extending portions 1158 can be easily changed as necessary.

A support member 1160 according to a thirteenth example will be explained. FIG. 29 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 portion 1161 that is provided along the central axis C1 of the heated tobacco cartridge 1001 and has a substantially circular cross section. An outer edge portion 1163, which is an outer circumferential surface of the main body portion 1161, contacts the packaging member 1016. The main body portion 1161 has a cutout portion 1162 in which a portion of the outer edge portion 1163 is cut out. Further, the main body portion 1161 has a through hole portion 1166 in the center portion.

The notch 1162 has a narrow groove shape, and the bottom has an arcuate cross section. The cutout portion 1162 becomes a flow path for airflow. Further, the through hole portion 1166 also serves as a flow path for 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 notches 1162 and the presence or absence, shape, and number of the through-holes 1166. Hereinafter, a modification having a notch will be described.

The support member 1170 in FIG. 30(a) has two notches 1172, and these notches 1172 are arranged at an angle of 180° with respect to each other.

The support member 1350 in FIG. 34(d) has a plurality of notches 1352 in which grooves are formed with smooth curved surfaces in a portion of the circumferential direction, and three through holes 1356.

The support member 1360 in FIG. 35(a) has a large number of notches 1362 having a substantially rectangular cross-sectional shape all around the circumferential direction. The support member 1370 in FIG. 35(b) has a large number of notches 1372 with substantially rectangular cross-sectional shapes all around the circumference, and has a through hole 1376 in the center. The support member 1380 in FIG. 35(c) has a plurality of notches 1382 each having a substantially rectangular cross-sectional shape in a portion of the circumferential direction, and three through-holes 1386. The support member 1390 in FIG. 35(d) has a notch 1392a having a substantially rectangular cross-sectional shape, a notch 1392b having a substantially triangular cross-sectional shape, and a notch 1392c having a smooth curved surface, respectively. A plurality of them are provided at different positions in the circumferential direction.

In this way, the support member having the notch can take various forms. In either case, the gap between the notch and the packaging member 1016 can be used as an air flow path. In each of the embodiments in which the notch is provided, the area of the solid portion of the support member is increased, so that the support function of the aerosol forming base material 1010 can be enhanced.

A support member 1400 according to a fourteenth example will be explained. FIG. 36 shows an end view of the support member 1400 of the fourteenth embodiment taken 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 center and the periphery.

The support member 1400 can adjust the fluidity of the airflow from the aerosol forming base material 1010 by adjusting the porosity, which is the ratio of the cross-sectional area of the through-hole portion 1406 to the cross-sectional area of the support member 1400. Further, the ventilation resistance can be adjusted by changing the thickness and material of the packaging member 1016. Since there is a slight gap between the packaging member 1016 and the support member 1400, when the inside of the packaging member 1016 becomes a negative pressure state by sucking the filter 1014, outside air is taken in through the packaging member 1016. The degree to which outside air is taken in changes depending on the ventilation resistance of the packaging member 1016.

When the airflow resistance of the packaging member 1016 is less than 30 kPa, the airflow resistance is low, so it is easy to take in outside air, and when combined with the airflow from the aerosol forming base material 1010, a mild taste can be obtained. In this case, the porosity of the support member 1400 is preferably less than 50%.

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

When the airflow resistance of the packaging member 1016 is 70 kPa or more, the airflow resistance is high, making it difficult to take in outside air, and the airflow from the aerosol forming base material 1010 becomes dominant, making it possible to obtain a strong and satisfying taste. In this case, the porosity of the support member 1400 is preferably 50% or more.

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=160000~400000 (3)
A4×B=5,000,000 to 6,500,000 (4)
