Description

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.

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 described in Patent Document 1.

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 a tobacco component. 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 component released from the aerosol-forming substrate by heating passes through the hollow part of the support member and is transported to a mouthpiece located downstream, where it is inhaled by the user.

First Embodiment
A heated tobacco cartridge according to a first embodiment of the present invention will be described in detail with reference to the drawings.

(1-1. Configuration of heated tobacco cartridge)
Fig. 1 is a cross-sectional view of a heated tobacco cartridge 1 having a tobacco filler accumulation 10 in this embodiment. As shown in Fig. 1, the heated tobacco cartridge 1 includes a tobacco filler accumulation 10, a heated tobacco support member 20 (hereinafter simply referred to as the support member 20), a filter 30 that serves as a mouthpiece, and a sheet-like packaging member 40. In the heated tobacco cartridge 1, the tobacco filler accumulation 10, the support member 20, and the filter 30 are arranged in a longitudinal direction D1
and are wrapped in a packaging member 40 to be integrated into one piece.

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

The tobacco filler 11 is formed by mixing aerosol formers that generate aerosols, microcrystalline cellulose, flavor additives, preservatives, adhesives or thickeners, etc. with dried and crushed non-tobacco plants, forming the mixture into a sheet, and then cutting it to a predetermined width and length. Note that the tobacco filler 11 is not limited to a long strip, and may have a variety of shapes. For example, it may be formed into a paste or granules.

When the tobacco filler 11 is configured in a long strip 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, and more preferably 0.
The length of the short side is preferably in the range of 0.1 mm to 1.0 mm, and more preferably in the range of 0.1 mm to 0.5 mm.
The length of the tobacco filler 11 is preferably approximately 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, and more preferably in the range of 10 mm to 20 mm.
The short side is 0.3 mm and the length is 12 mm.

The support member 20 inhibits the movement of the tobacco packing accumulation 10 toward the support member 20, and allows the airflow containing the aerosol generated in the tobacco packing accumulation 10 to flow toward the filter 30. The support member 20 is provided, for example, in a cylindrical and solid shape, and is disposed between the tobacco packing 11 and the filter 30 so that its axial direction is along the central axis C. The support member 20 is formed, for example, so that its length along the central axis C is 3.0 mm to 50 mm or less.
The support member 20 may have dimensions different from those described above depending on the function and configuration.
The other configurations will be described later.

The filter 30 is formed in a cylindrical shape, for example, with a diameter of 6.5 mm to 7.5 mm and a central axis C
The filter 30 is formed so that the length along the line is 50 mm or less. The filter 30 is a part that constitutes the mouthpiece of the cartridge 1 for a smoking article. The filter 30 is formed using, for example, paper. The filter 30 may also be formed into a cylindrical shape by rolling up a sheet-like member made of, for example, paper, or
The filter 30 may include a cellulose acetate filter or the like for removing fine particles. The filter 30 has the function of filtering out some of the fine particles in the water vapor and aerosol generated in the tobacco filler assembly 10.

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 length is set in the range of 40 to 60 mm, the diameter will be smaller than the insertion hole provided in the heated smoking device for inserting the heated tobacco cartridge, 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 in the range of 40 to 60 mm, the length will be longer than the length of the insertion hole provided in the heated smoking device for receiving the heated tobacco cartridge, so even when the heated tobacco cartridge 1 is inserted into the smoking device, the mouthpiece can be exposed from the heated smoking device, and the length necessary for the smoker to smoke can be ensured.

The tobacco filler assembly 10 has a length of 10 to 25 mm. Setting the length of the tobacco filler assembly 10 to 10 mm or more ensures the minimum length required for inserting the heating element 52. Setting the length of the tobacco filler assembly 10 to 25 mm or less ensures a length sufficient to spread the heat of the heating element 52 to every corner of the tobacco filler 11. The heated tobacco cartridge 1 may have dimensions different from those described above, depending on the shape of the heated tobacco body.

2 is a cross-sectional view showing a usage state of the heated tobacco cartridge 1. The heated tobacco cartridge 1 is used by being attached to a heated tobacco body 5. The heated tobacco body 5
has an insertion section 50 into which the heated tobacco cartridge 1 is inserted. The insertion section 50 is provided with a needle- or blade-shaped heating element 52 that is inserted into the tobacco filler 11 of the inserted heated tobacco cartridge 1. The heating element 52 is electrically controlled by a control section provided inside the heated tobacco body 5. The heating element 52 generates heat while inserted into the tobacco filler 11, thereby generating an aerosol from the tobacco filler 11. In this state, the user can inhale an airflow containing the aerosol by inhaling through the filter 30. Furthermore, the support member 20 is solid and provided between the tobacco filler accumulation 10 and the filter, thereby preventing the tobacco filler accumulation 10 from moving toward the filter 30.

(1-2. Configuration of Support Member 20)
The support member 20 will be described in detail below.

Fig. 3 is a perspective view of the support member 20. As shown in Fig. 3, the support member 20 has a first end surface 21, a second end surface 23, and a peripheral surface portion 25. The first end surface 21 of the support member 20 abuts against the end surface of the tobacco filler stack 10. The second end surface 23 of the support member 20 abuts against the end surface of the filter 30. The support member 20 has holes 27 (also called through holes) extending from the first end surface 21 to the second end surface 23, and air flows through the holes 27. The support member 20 is provided in a cylindrical shape. The material for forming the support member 20 is, for example, silicone resin. Note that the material for the support member 20 is not limited to silicone resin, and wood, metal (aluminum, etc.), etc., which have an increased cooling effect, may also be used.
The insulating film 10 may be formed of a material other than a resin material, such as

Fig. 4(A) is a side view of the support member 20. Fig. 4(B) is a front view of the first end surface 21 of the support member 20. As shown in Fig. 4(A) and Fig. 4(B), the support member 20 has the same shape from the first end surface 21 to the second end surface 23 in a cross section taken along a plane perpendicular to the longitudinal direction D1.

The support member 20 has a hole 27 that penetrates from the first end surface 21 to the second end surface 23 .
The holes 27 allow the airflow containing the aerosol generated in the tobacco filler accumulation 10 to pass through the filter 30.
It functions as a flow path to allow the fluid to flow to the other side.

As shown in Figures 4A and 4B, 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.
In this embodiment, six holes 27 are provided along the circumferential direction. At this time, the centers P of the holes 27 are arranged at intervals of 60° in the circumferential direction around the central axis C20. Therefore, the six holes 27 are arranged at equal intervals in the circumferential direction.
have the same radius.

The first end surface 21 has a gap at the hole 27 and a solid portion at the other end. This solid portion abuts against the end surface of the tobacco filler accumulation 10. When the heating element 52 of the heated tobacco body 5 is inserted, the tobacco filler accumulation 10 receives a force in the longitudinal direction D1, and therefore the abutting solid portion of the support member 20 can support the tobacco filler accumulation 10.

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

Each of the plurality of protrusions 251 has a tip 251a.
In FIG. 4B, the imaginary line VL1 extending from the center C251 of the protrusion 251 toward the tip 251a when viewed from the first end face 21 side is the same as the imaginary line extending in the radial direction D2 from the central axis C20 of the support member 20. The protrusion 251 has two side portions S25
1, and the two side portions S251 each connect the tip portion 251a and the peripheral surface portion 25. In this case, when the support member 20 is viewed from the first end surface 21 side, the angle θ formed between the imaginary line VL1 and an imaginary line VL2 provided along the side portion S251 corresponding to the tip portion 251a of the convex portion 251 is an acute angle.

In this embodiment, by providing the protrusion 251 on the peripheral surface 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 251 a of the protrusion 251. This makes it easier for the gripping portion of the assembly machine to grip the support member 20, and enables stable production of heated tobacco cartridges.

5 is a cross-sectional view of the support member 20 wrapped in the packaging member 40. As shown in FIG. 5, in this embodiment, the packaging member 40 wrapped around the outer periphery of the support member 20 and the support member 2 are
A gap 26 is provided between the peripheral surface 25 of the nozzle 20 and the projection 251 .
This allows aerogas to circulate between packaging member 40 and peripheral surface portion 25. Therefore, the flow path of the aerogas is expanded in addition to hole portion 27, improving the fluidity of the aerogas. Furthermore, in the present embodiment, gap 26 has a shape that expands toward packaging member 40, so the flow path of the aerosol can be made larger than when, for example, the convex portion has a substantially rectangular shape.

Furthermore, in this embodiment, the convex portions 251 each have the same height in the longitudinal direction D1. In this case, the height of the convex portions 251 is preferably 0.05 mm or more and 1 mm or less. This is because, if the height of the convex portions 251 is less than 0.05 mm, it may be difficult to maintain the shape of the convex portions, or the aerosol may not flow smoothly. Furthermore, if the height of the convex portions 251 exceeds 1 mm, the size of the gap between the support member 20 and the packaging member 40 increases, causing part of the tobacco filler 11 to enter the gap, which may make it difficult to prevent the tobacco filler assembly 10 from moving toward the filter 30. The above range is also desirable from the viewpoint of maintaining the shape of the convex portions.

Furthermore, in this embodiment, the fluidity of the aerosol (airflow) from the tobacco filler assembly 10 can be adjusted by adjusting the porosity between the peripheral surface portion 25 and the packaging member 40, as well as the porosity of the support member 20, which is the ratio of the cross-sectional area of the through holes to the cross-sectional area of the support member 20. Details of the porosity will be described later.

When the support member 20 of this embodiment is packaged in the packaging member 40, the peripheral surface portion 25 and the packaging member 40
A plurality of gaps 26 are provided between the electrodes 22 and the aerosol, and these gaps can serve as flow paths for the aerosol.
The voids in the first end surface of the support member 20 are a void 26 and six holes 27, and the ratio of the void ratio between the void 26 and the holes 27 is preferably in the range of 1:1 to 1:12, for example.
The void ratio of void 6 is preferably in the range of 1% to 5% of the area surrounded by packaging member 40, and the void ratio of hole 27 is preferably in the range of 1% to 60%. If void 26 exceeds the upper limit of the above range, packaging member 40 may be crushed when pressure is applied from the outside, making it impossible to maintain the shape of the cartridge as a whole, or the support function of support member 20 may not be maintained (for example, the tobacco filler accumulation may easily enter void 26 and hole 27).
Furthermore, if the gap 26 is below the lower limit of the above range, the flow of the aerosol may be impaired (for example, the flow path becomes narrower, the amount of aerosol flowing decreases, and therefore, more force is required for suction).

In other words, by using this embodiment, when pressure is applied from the outside, the packaging member 4
The solid portion of the support member 20 prevents the tobacco filler assembly 10 from moving toward the support member 20 without the assembly 0 being crushed, and multiple gaps 26 are provided between the support member 20 and the packaging member 40, allowing the aerosol to flow through the gaps 26 in addition to the holes 27, thereby enhancing the effect of circulating the aerosol.

In addition to the porosity, the airflow resistance may be adjusted by the thickness and material of the packaging member 40. In this embodiment, a gap 26 is provided between the packaging member 40 and the support member 20.
When the filter 30 is sucked and the inside of the packaging member 40 becomes a negative pressure state, outside air is taken in through the packaging member 40. At this time, the degree to which outside air is taken in can be changed by the airflow resistance of the packaging member 40.

Second Embodiment
In the first embodiment of the present invention, an example was shown in which the protrusions were arranged to extend in the longitudinal direction of the peripheral surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member in which the protrusions are arranged in a direction inclined with respect to the longitudinal direction will be described. Note that in this embodiment, descriptions of configurations similar to those of the first embodiment will be omitted as appropriate.

FIG. 6 is a side view of the support member 20A. As shown in FIG. 6, the support member 20A has a protrusion 251A on the peripheral surface 25A. The protrusion 251A may extend in a direction intersecting the longitudinal direction D1. Specifically, the protrusion 251A is provided in a direction inclined relative to the longitudinal direction D1. In this case, the aerosol flow path is longer than when the protrusion 251A extends in the longitudinal direction D1, thereby increasing the cooling time. Therefore, by using this embodiment, the gripping portion (manufacturing device) of the assembly machine can more easily grip the support member 20A, enabling stable production of heated tobacco cartridges and enabling a change in the smoking experience when inhaling the aerosol compared to when the protrusion 251A is provided linearly.

Third Embodiment
In the first embodiment of the present invention, an example was shown in which the protrusions were arranged in the longitudinal direction of the peripheral surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member having protrusions arranged in a curved line will be described. Note that in this embodiment, descriptions of the same configuration as in the first embodiment will be omitted as appropriate.

7 is a side view of the support member 20B. As shown in FIG. 7, on the peripheral surface 25B of the support member 20B, the protrusions 251B may have a tip and be arranged in a curved shape from the first end surface 21 to the second end surface 23. In this case, the aerosol flow path can be made longer than when the protrusions 251B extend linearly in the longitudinal direction D1. This makes it easier for the manufacturing machine (assembly machine) to grip the cartridge, allowing for stable production of heated tobacco cartridges, and can affect the smoking experience when the smoker inhales the aerosol, compared to when the protrusions are arranged linearly.

Fourth Embodiment
In this embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member in which protrusions are provided in a wave-like shape from a first end face toward a second end face will be described.
In this embodiment, the description of the same configuration as in the first embodiment will be omitted as appropriate.

8A is a side view of the support member 20C.
8A and 8B, the end surface 21 of the support member 2 is viewed from the front.
0C, the protrusion 251C extends from the first end surface 21 to the second end surface 23 in the longitudinal direction D1
The protrusions 251C may be arranged in a wave-like shape. In this case, the aerosol flow path can be made longer than when the protrusions 251C extend linearly in the longitudinal direction D1. This also changes the cooling time of the aerosol. Therefore, by using this embodiment, the gripping portion (manufacturing device) of the assembly machine can easily grip the support member 20C, allowing for stable production of heated tobacco cartridges and enabling a change in the smoking experience when a smoker inhales the aerosol compared to when the protrusions 251C are arranged linearly.

Fifth Embodiment
In this embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member in which protrusions are provided along the circumferential direction will be described. In this embodiment,
Description of the same configuration as in the first embodiment will be omitted where appropriate.

9A is a side view of the support member 20D.
9A and 9B, the end surface 21 of the support member 2 is viewed from the front.
The support member 20D has a first end surface 21, a second end surface 23, and a circumferential surface portion 25D. The circumferential surface portion 25D of the support member 20D has a protruding portion 251D. The protruding portion 251D has a tip portion 251Da and may be provided along the circumferential direction. In this case, in FIG. 9A, a virtual line VL1 extending from the center C251D of the protruding portion 251D toward the tip portion 251Da is aligned with the support member 20D.
The line S251D is the same as an imaginary line extending in the radial direction D2 from the central axis C20D of the support member 20. The protrusion 251D has two side portions S251D, and each of the two side portions S251D connects the tip portion 251Da and the peripheral surface portion 25D. In this case, when the support member 20D is viewed from the peripheral surface portion 25D side,
The angle θ formed by the imaginary line VL1 and an imaginary line VL2 provided along the side portion S251D corresponding to the tip end 251Da of the convex portion 251D is an acute angle.

The number of protrusions 251D is controlled by the length of the support member 20D in the longitudinal direction. In this embodiment, the number of protrusions 251D that come into contact with the gripping part of the assembly machine increases compared to when the protrusions 251 extend in the longitudinal direction D1. As the number of contacting protrusions 251D increases, a large frictional force is likely to occur when the gripping part of the assembly machine and the support member 20D come into contact. Therefore, by using this embodiment, the gripping part (manufacturing device) of the assembly machine can easily contact the support member 20D.
This makes it easier to grip, allowing for stable production of heated tobacco cartridges.

Sixth Embodiment
In this embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member in which a plurality of protrusions are provided so as to intersect with each other will be described. Note that in this embodiment, descriptions of the same configuration as in the first embodiment will be omitted as appropriate.

Fig. 10(A) is a side view of the support member 20E. Fig. 10(B) is a front view of the first end surface 21 of the support member 20E. As shown in Figs. 10(A) and 10(B), the support member 20E includes a plurality of protrusions 251E on a peripheral surface portion 25E. The protrusions 251E are
The protrusion 251E1 has a tip end 251E1a and is provided along the longitudinal direction D1. The protrusion 251E2 has a tip end 251E2a and is provided along the circumferential direction. The protrusions 251E1 and 251E2 are
They may be provided so as to intersect with each other.

In this case, the height of the protrusion 251E1 and the height of the protrusion 251E2 may be different. In this example, the height of the protrusion 251E2 is greater than the height of the protrusion 251E1. This increases the number of protrusions 251E2 that come into contact with the gripping portion of the assembly machine. As the number of contacting protrusions increases, a large frictional force is more likely to occur when the gripping portion of the assembly machine comes into contact with the support member 20E.

Furthermore, in this embodiment, the convex portions 251E1 and the circumferential convex portions 251E2 intersect to form grid-like grooves 251EV. The grooves 251EV allow the aerosol to partially accumulate. This diversifies the aerosol flow path and allows the aerosol to cool down over different times. Therefore, by using this embodiment, the gripping portion (manufacturing device) of the assembly machine can easily grip the support member 20E, enabling stable production of heated tobacco cartridges and enabling a change in the smoking experience when the smoker inhales the aerosol compared to when the convex portions are arranged linearly.

Seventh Embodiment
In the first embodiment of the present invention, an example was shown in which the support member has projections and recesses over the entire length of the peripheral surface portion 25 in the longitudinal direction D1 and the entire circumferential direction, but the present invention is not limited to this. In this embodiment, a support member 20 different from that in the first embodiment will be described. The support member 20 will be described in which the projections 251 are provided in a partial region of the peripheral surface portion 25.

11 to 14 are side views of the support member 20F. As shown in Fig. 11 to 14, the support member 20F has a protrusion 251F on a peripheral surface portion 25F. The protrusion 251F may be provided in a partial region of the peripheral surface portion 25F.

In this case, as shown in Fig. 11(A), the grooves 11 may be wider in the circumferential direction than in the longitudinal direction D1, or as shown in Fig. 11(B), the grooves 11 may be wider in the longitudinal direction D1 than in the circumferential direction.

Further, the support member 20F may be provided in a plurality of regions. For example, as shown in FIG. 12A, when the protrusion 251F is provided widely in the circumferential direction, the protrusion 251F may be provided in the longitudinal direction D1.
12B, when the convex portion 251 is provided widely in the longitudinal direction D1, the convex portion 251F may be provided in a plurality of regions in the circumferential direction.

As shown in FIG. 13A, the protrusion 251F is formed on a part of the peripheral surface 25F.
13B, the protrusions 251F may be provided over the entire circumference of the protrusion 251F in the longitudinal direction D1.

As shown in FIG. 14A, the protrusion 251F is formed on a part of the peripheral surface 25F.
The protrusions 251F may be provided over the entire length of the protrusion 251F in the longitudinal direction D1. In this case, as shown in Fig. 14B, the protrusions 251F may be provided in a plurality of regions in the circumferential direction.

In the configuration of this embodiment, the protrusion 251F is provided on the peripheral surface 25F, which makes it easier for frictional force to be generated when the assembly machine grips the support member 20F, making it easier for the gripping portion of the assembly machine to grip the support member 20F, and enabling stable production of heated tobacco cartridges.

Eighth Embodiment
In the first embodiment of the present invention, the support member has a protrusion 251 in the longitudinal direction D1 of the peripheral surface portion 25.
However, the present invention is not limited to this. In this embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member provided with a protruding protrusion will be described.

Fig. 15(A) is a side view of the support member 20G. Fig. 15(B) is a view showing the first end surface 21 of the support member 20G as viewed from the front. As shown in Figs. 15(A) and 15(B), the peripheral surface portion 25G has a convex portion 251G. The convex portion 251G has a protruding shape. The convex portion 251G
are arranged in the longitudinal direction D1 and the circumferential direction.
In FIG. 15B, the center C251 of the convex portion 251 when viewed from the first end face side is
The imaginary line VL1 extending from the center line G to the tip end 251Ga is aligned with the central axis C2 of the support member 20G.
The protrusion 251G is the same as the imaginary line extending from 0G in the radial direction D2.
The two side portions S251G each connect the tip portion 251Ga and the peripheral surface portion 25G. In this case, when the support member 20G is viewed from the first end surface 21 side, the imaginary line VL1
and an imaginary line VL2 provided along the side portion S251G corresponding to the tip end 251Ga of the convex portion 251G, an angle θ formed by the imaginary line VL2 is an acute angle.

In this embodiment, the number of convex portions 251G provided is equal to the number of protrusions, which increases the frictional force between the support member 20G and the gripping portion of the assembly machine when manufacturing the heated tobacco cartridge, making it easier for the gripping portion of the assembly machine to grip the support member 20G, and enabling stable manufacturing of heated tobacco cartridges.

In the present embodiment, the adjacent convex portions 251G are arranged in the longitudinal direction D1, but this is not limiting.
may be arranged in a direction intersecting the longitudinal direction D1.

Fig. 16(A) is a side view of the support member 20H. Fig. 16(B) is a view showing the first end surface 21 of the support member 20H as the front. As shown in Fig. 16(A), the protrusions 251H may be arranged in a zigzag pattern in a diagonal direction with respect to the longitudinal direction D1. In this case, as shown in Fig. 16
As shown in (B), when viewed from the first end face 21 side, adjacent convex portions 251H partially overlap. This makes the aerosol flow path longer than when the aerosol flows linearly. This increases the aerosol cooling time. This makes it easier for the assembly machine to grip, allowing for stable production of heated tobacco cartridges.
This allows smokers to change the sensation of smoking when inhaling aerosol.

Ninth Embodiment
In the first embodiment of the present invention, an example was shown in which the protrusions were arranged to extend in the longitudinal direction of the peripheral surface of the support member, but the present invention is not limited to this. In this embodiment, a support member different from the first embodiment will be described. Specifically, a support member having a recess extending in the longitudinal direction on the peripheral surface will be described. Note that in this embodiment, descriptions of configurations similar to those of the first embodiment will be omitted as appropriate.

Fig. 17(A) is a side view of the support member 20J. Fig. 17(B) is a front view of the first end surface 21 of the support member 20J. As shown in Figs. 17(A) and 17(B), the peripheral surface portion 25J of the support member 20J has a recess 252. The recess 252 is linearly arranged in the longitudinal direction D1 from the first end surface 21 toward the second end surface 23.

17B, the recess 252 has two side portions S252J, and the two side portions S252J each connect the tip portion 252a and the peripheral surface portion 25J.
When the support member 20J is viewed from the end surface 21 side, a virtual line VL1 extending from the center C252 of the recess 252 to the tip end 252a when viewed from the first end surface 21 side and a virtual line VL2 extending from the center C252 of the recess 252 to the tip end 252a are intersected.
The angle θ formed by the imaginary line VL2 along the side portion S252 corresponding to 52a is an acute angle.

In this embodiment, the support member 20J has the recess 252, which makes it easier for the tip of a gripping part of an assembly machine to catch on the support member 20J. As a result, the gripping part of the assembly machine can easily grip the support member 20J, allowing for stable production of heated tobacco cartridges.

In this embodiment, an example is shown in which the recess 252 is arranged linearly in the longitudinal direction D1 from the first end face 21 to the second end face 23, but it may also be arranged to match the shapes described in the second to seventh embodiments, etc.

Tenth Embodiment
In the eighth embodiment of the present invention, an example was shown in which the support member had a protruding convex portion on the peripheral surface thereof.
The present invention is not limited to this. In this embodiment, a support member different from that of the eighth embodiment of the present invention will be described. Specifically, an example having a recessed portion in a recessed shape will be described.

Fig. 18(A) is a side view of the support member 20K. Fig. 18(B) is a view showing the first end surface 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 recesses 252K. Each recess 252K has a hollow shape with a tip end portion 252Ka. The recesses 252K are arranged in the longitudinal direction D1 and the circumferential direction.
2K each have a tip portion 252Ka.

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

In addition, in this embodiment, the aerosol remains in the recess 252K, changing the flow path of the aerosol, which can affect the smoking experience when the smoker inhales the aerosol.

Eleventh Embodiment
In this embodiment, a support member different from that in the first embodiment will be described. Specifically, a support member having a plurality of minute protrusions provided in the circumferential direction will be described. Note that in this embodiment, descriptions of the same configuration as in the first embodiment will be omitted as appropriate.

19(A) is a side view of the support member 20L. FIG. 19(B) is a front view of the first end surface 21 of the support member 20L and an enlarged view of a portion thereof.
), in the peripheral surface portion 25L of the support member 20L, the first end surface 21 to the second end surface 22
A plurality of minute protrusions 251L may be arranged in the longitudinal direction D1 toward the nozzle 3. The minute protrusions 251L have pointed tip portions 251La.

The support member 20L has six hole portions 27L (through holes). Of the six through holes, five are evenly spaced apart at 72 degrees in the circumferential direction.
The two through holes are arranged in the center of the first end surface 21 .

In this embodiment, 100 to 150 fine protrusions 251L may be arranged in the circumferential direction.
In this example, 137 minute protrusions 251L are arranged in the circumferential direction. In this example, the diameter of the support member is 7 mm, and the height T251L of the protrusions 251L is 0.1 mm. The width W between the tip ends 251La of adjacent protrusions 251L is
251La (also called pitch) is 0.16 mm.

This embodiment increases the contact area (contact points) with the gripped member while maintaining the shape of the protrusions. This increases the friction between the gripping unit of the assembly machine and the support member. This makes it easier for the gripping unit of the assembly machine to grip the support member.

Furthermore, when the support member of this embodiment is packaged in a packaging material, the peripheral surface portion 25L and the packaging material 40
A plurality of gaps 26 are provided between the electrodes 22 and the aerosol, and these gaps can serve as flow paths for the aerosol.
In this case, the gaps in the first end surface of the support member 20L are the gap 26 and six holes 27L. The ratio of the void ratios of the gap 26 and the holes 27L is preferably in the range of 1:1 to 1:12, for example. The void ratio of the gap 26 is preferably in the range of 2% to 4% of the area surrounded by the packaging member 40, and the void ratio of the holes 27L is preferably in the range of 2% to 48%. If the gap 26 exceeds the upper limit of the above range, the packaging member 40 may be crushed when pressure is applied from the outside, making it impossible to maintain the shape of the cartridge as a whole, or the support function of the support member 20 may not be maintained (for example, the tobacco filler 11 of the tobacco filler assembly 10 may easily enter the gap 26 and the holes 27). Furthermore, if the gap 26 falls below the lower limit of the above range, the flow of the aerosol may be impaired (for example, the flow path may become narrower, reducing the amount of aerosol flow, requiring more force for suction). In this embodiment, the porosity of the hole 27 is 30
%, and the porosity of the voids 26 is 3%.

In other words, by using this embodiment, the solid portion of the support member 20L suppresses the movement of the tobacco filler assembly 10 toward the filter 30, and by providing multiple gaps 26 between the support member 20L and the packaging member 40, the aerosol can flow through the gaps 26 in addition to the hole portion 27L, thereby enhancing the effect of circulating the aerosol.

(Modification)
Within the scope of the concept of the present invention, those skilled in the art may conceive of various modifications and alterations, and it is understood that these modifications and alterations also fall within the scope of the present invention. For example, those skilled in the art may add, delete, or modify components or add, omit, or change conditions of processing to the above-described embodiments as appropriate, and such modifications and alterations are also included within the scope of the present invention as long as they maintain the gist of the present invention. Furthermore, the configurations of the various embodiments may be combined as appropriate.

In the first embodiment of the present invention, an example was shown in which the heated tobacco cartridge 1 includes a tobacco filler assembly 10, a support member 20, and a filter 30 serving as a mouthpiece. 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. A cavity may also be provided between the support member and the filter to improve breathability. In this case, the cavity may be provided in a range of 1 mm to 20 mm. This results in a wide cavity, which can improve the amount of aerosol generated by the heated aroma-generating element that is absorbed. Furthermore, the cavity also functions as an exchange space, resulting in an excellent taste. Furthermore, even if manufacturing errors cause defects such as tea leaves or filters being slightly longer, the provision of this cavity can absorb the manufacturing defects.

The heated tobacco cartridge 1 includes a tobacco filler assembly 10 and a support member 20
In this case, the heated tobacco cartridge 1 does not need to have a filter.

In the first embodiment of the present invention, the holes 27 (through holes) have the same radius and a circular shape, but are not limited to this. The holes 27 may have different radii. Furthermore, the holes 27 may be elliptical or rectangular.

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

In the first embodiment of the present invention, an example in which a plurality of convex portions or concave portions are provided is shown, but the present invention is not limited to this. The object of the present invention can be achieved by providing at least one convex portion or concave portion.

In the first embodiment of the present invention, the protrusions 251 have the same height, but the present invention is not limited to this. The protrusions 251 may have different heights.
Furthermore, when the convex portions 251 extend in the longitudinal direction D1, the height of the convex portions 251 may vary in the longitudinal direction D1. Furthermore, when the convex portions 251 extend along the circumferential direction, the height of the convex portions 251 may vary in the circumferential direction. Furthermore, the heights of adjacent convex portions 251 may differ. This diversifies the aerosol flow path. Therefore, it is possible to change the drawing comfort of the aerosol obtained in the heated tobacco cartridge.

In the first embodiment of the present invention, the distance from the center of the protrusion 251 to the tip 25
1a is the same as the imaginary line VL1 extending from the central axis C20 of the support member 20 in the radial direction D2, but is not limited to this.
As shown in FIG. 20, the first end surface 21 of the support member 20M is viewed from the front.
The support member 20M has a protrusion 251M. An imaginary line VL1 extending from the center C251M of the protrusion 251M toward the tip 251Ma may be different from an imaginary 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 imaginary lines VL1 and VL3 is less than 5 degrees. This allows the center and tip 251Ma of the protrusion 251 of the first embodiment to be aligned in a straight line.
51a are provided on the same imaginary line, the same effect can be obtained.

Furthermore, in the fourth embodiment of the present invention, the protrusions 251C are arranged to have a wave shape in the longitudinal direction D1, but this is not limiting. The protrusions 251N of the support member 20N may be arranged in the circumferential direction or in a direction oblique to the longitudinal direction D1. FIG. 21 is a side view of the support member 20N. For example, as shown in FIG. 21, the protrusions 251N may each be arranged to have a wave shape in a direction intersecting the longitudinal direction D1.

Furthermore, in the sixth embodiment of the present invention, the plurality of protrusions 251 are arranged to intersect in the longitudinal direction D1 and the circumferential direction, but the present invention is not limited to this. For example, some of the plurality of protrusions 251E may extend in a direction inclined relative to the longitudinal direction D1 or the circumferential direction. The protrusions 251E may intersect in the longitudinal direction D1 and the circumferential direction and have a wavy shape. This diversifies the aerosol flow path, allowing for changes in the smoking experience when the smoker inhales the aerosol.

In addition, although the respective embodiments of the present invention have shown examples in which the recesses or protrusions are provided with a certain regularity, the present invention is not limited to this. Fig. 22 is a side view of the support member 20P.
As shown in FIG. 1, the support member 20P has a protrusion 251P on the peripheral surface 25P.
The protrusions 251P may be arranged irregularly. In this case, the provision of the protrusions 251P generates friction between the gripping portion of the assembly machine and the protrusions, diversifying the aerosol flow path and enabling changes in the smoking experience when a smoker inhales the aerosol. This makes it easier for the assembly machine to grip the protrusions, enabling stable production of heated tobacco cartridges, and enabling different smoking experiences for the aerosol.

Furthermore, in the embodiment of the present invention, an example having a tip portion is shown, but the present invention is not limited to this.
23 is a cross-sectional view of the support member 20Q and an enlarged view of the protrusion 251Q. As shown in FIG. 23, the upper portion 251Q of the protrusion 251Q of the peripheral surface portion 25Q of the support member 20Q may be flat. In this case, when the support member 20 is viewed from the first end surface 21 side, the protrusion 251Q
The width W251Qu of the upper portion 251Qu of the protrusion 251 is
This makes it possible to achieve the same effect as when the convex portion has a tip (apex).

In the first embodiment of the present invention, an example in which one protrusion has a tip end portion with one apex formed thereon is shown, but the present invention is not limited to this.
As shown in FIG. 24, the support member 20R has a protrusion 2 on a peripheral surface 25R.
The protrusion 251R may have a tip 251Ra on which a plurality of apexes are formed. In this case, the center C251R of the protrusion and one apex 251 at the tip 251Ra are
The angle formed by the imaginary line VL1R connecting the top portion 251Ra1 and the imaginary line VL2R along the side portion S251R corresponding to the top portion 251Ra1 is an acute angle. This increases the contact area (contact points) with the gripped member. This increases the frictional force between the gripping portion of the assembly machine and the support member. This makes it easier for the gripping portion of the assembly machine to grip the support member.

In the first embodiment of the present invention, an example has been described in which the convex portion has two sides when the first end face 21 is the front face, but the present invention is not limited to this. The convex portion may have an arc shape.

Fig. 25(A) is a side view of the support member 20S. Fig. 25(B) is a view showing the first end surface 21 of the support member 20S as viewed from the front. As shown in Figs. 25(A) and 25(B), the support member 20S has protrusions 251S on a peripheral surface 25S. The protrusions 251S are arranged in the longitudinal direction D1 and the circumferential direction. Each of the protrusions 251S has a tip end 251Sa.
In (B), the distance from the center C251S of the protrusion 251S to the tip 25
The imaginary line VL1 extending toward the center axis C20S of the support member 20 in the radial direction D2
The protrusion 251S includes an arc S251S, and the tip 251S
a and the peripheral surface portion 25S.

In this embodiment, the protrusion 251S is provided on the peripheral surface 25S, so that when the gripping portion of the assembly machine grips the support member 20S, the gripping portion of the assembly machine and the tip end 21 of the protrusion 251S are in contact with each other.
A frictional force is generated between the support member 20S and the support member Sa. This makes it easier for the gripping portion of the assembly machine to grip the support member 20S, and allows for stable production of heated tobacco cartridges.
