Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional view of a heat-not-burn tobacco cartridge 1 having a tobacco filler aggregate 10 according to the present embodiment. As shown in this figure, the heat-not-burn tobacco cartridge 1 includes a substantially cylindrical tobacco filler aggregate 10 filled with a large number of tobacco fillers 20, and a heat-not-burn tobacco support member 12 (hereinafter, simply referred to as a support member 12). ) And the filter 14 serving as a mouthpiece are arranged along the length direction and are integrally formed by being wound by a sheet-shaped packaging member 16.

The tobacco filling aggregate 10 is formed so that the long tobacco filling 20 is bundled along the length direction and is wound around the sheet-shaped packaging 25 to form a substantially cylindrical shape. .. The tobacco filling 20 is formed from non-tobacco plants. However, the tobacco filling 20 may be made of tobacco.

The tobacco filling 20 is a sheet obtained by mixing an aerosol former that generates an aerosol, microcrystalline cellulose, an additive that adds flavor, a preservative, an adhesive, a thickener, or the like with a dried / crushed non-tobacco plant. It is formed by forming it into a shape and then cutting it so as to have a predetermined width and length. However, the tobacco filling 20 may be formed in the form of dust.

The support member 12 circulates the air flow containing the aerosol generated in the tobacco filling aggregate 10 to the filter 14 side. The first end surface 30 of the support member 12 is in contact with the end surface of the tobacco filling aggregate 10, and the second end surface 31 of the support member 12 is in contact with the end surface of the filter 14. The support member 12 has a hole portion 40 extending from the first end surface 30 to the second end surface 31, and an air flow flows through the hole portion 40. The filter 14 is a sponge-like porous body and is formed in a cylindrical shape.

In the present embodiment, the heat-not-burn 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 aggregate 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 a usage pattern of the heat-not-burn tobacco cartridge 1. The heat-not-burn tobacco cartridge 1 is used by being attached to the heat-not-burn tobacco body 2. The heat-not-burn tobacco body 2 has an insertion portion 51 into which the heat-not-burn tobacco cartridge 1 is inserted. The insertion portion 51 is provided with a needle-shaped or blade-shaped heating portion 50 to be inserted into the tobacco filling 20 of the inserted heated tobacco cartridge 1. The heating unit 50 can generate an aerosol from the tobacco filling 20 by generating heat while being inserted into the tobacco filling 20. In this state, the user can suck the air flow containing the aerosol by sucking it from the filter 14.

The support member 12 will be described in detail. FIG. 3 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 forming the support member 12 include those such as silicon. However, the support member 12 may be made of a resin material other than this, or a material other than the resin material such as wood and metal (aluminum, etc.) having an increased 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 40 functions as a flow path for passing the air flow containing the aerosol generated in the tobacco filling aggregate 10 to the filter 14 side.

FIG. 4 is a view with 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 orthogonal to the length direction. Therefore, the cross-sectional shape is also the same as that in FIG.

As shown in FIG. 4, the hole portion 40 has a first through hole 41 arranged on the outer peripheral portion so as not to include the central axis C of the peripheral surface portion 32. The first through hole 41 has an elliptical shape and has a shape longer in the circumferential direction than the radial direction of the support member 12. Three first through holes 41 are provided along the circumferential direction. The elliptical center P of the first through hole 41 is arranged on a virtual circle V having a constant radius from the central axis C, respectively. Further, the elliptical centers P are arranged with an interval of 120 ° in the circumferential direction about the central axis C. Therefore, the three first through holes 41 are arranged at equal intervals in the circumferential direction.

In the first end surface 30, the portion of the hole 40 is a void and the other portion is solid, and this solid portion abuts on the end surface of the tobacco filling aggregate 10. Since the tobacco filler 10 receives a force in the length direction when the heating portion 50 of the heat-not-burn tobacco body 2 is inserted, the tobacco filler 10 is placed at the solid portion of the support member 12 that abuts. Can be supported. The hole portion 40 of the present embodiment is arranged on the outer peripheral portion of the support member 12 so as not to include the central axis C of the peripheral surface portion 32, and has a shape longer in the circumferential direction than 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, since the solid portion of the outer peripheral portion of the first end surface 30 can be widened, the tobacco filling aggregate 10 can be reliably supported. Further, since the solid portion of the outer peripheral portion of the first end surface 30 is wide, it is possible to prevent the shape from being crushed when the portion of the support member 12 is held by hand.

The area of the hole 40 with respect to the area of the first end face 30 is calculated as a porosity. The porosity can be set in the 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 forming the first through hole 41 into a shape that is long in the circumferential direction of the support member 12, a thick solid portion is formed on the outer peripheral portion while ensuring a porosity and improving the fluidity of the air flow, and the tobacco filling is accumulated. The retention of the body 10 can also be improved.

Next, a first modification of the support member will be described. FIG. 5 shows a perspective view of the support member 13 according to the first modification.

There is. The hole 40 has the same shape as the support member 12 shown in FIGS. 3 and 4.

The support member 13 of FIG. 5 has a large number of uneven portions 45 on the peripheral surface portion 32. 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 so as to extend over the entire length in the length direction from the first end surface 30 to the second end surface 31 of the peripheral surface portion 32 of the support member 13.

FIG. 6 shows a cross-sectional view of the support member 13 according to the first modification provided in the heat-not-burn tobacco cartridge 1 cut along a plane orthogonal to the length direction. As shown in this figure, a large number of small gaps 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 part of the air flow from the tobacco filling aggregate 10 to the filter 14 can be circulated. As a result, the flow path of the air flow can be expanded by adding it to the hole 40, and the fluidity can be further improved.

Further, since the uneven portion 45 is formed on the peripheral surface portion 32, the support member 13 can be easily gripped by the assembling machine at the time of manufacturing the heat-not-burn tobacco cartridge 1, and the manufacturing can be facilitated. can.

FIG. 12 shows a cross-sectional view of the heat-not-burn tobacco cartridge 1001 according to the present embodiment. As shown in this figure, the heat-not-burn tobacco cartridge 1001 has an aerosol-forming base material 1010 provided at one end thereof, a heat-not-burn tobacco support member 1012 (hereinafter simply referred to as a support member 1012), and a filter 1014 serving as a mouthpiece. , Arranged along the length direction, and integrally formed by being wound with a sheet-shaped packaging member 1016. The support member 1012 is schematically shown in FIG. Further, the configuration of the heat-not-burn tobacco cartridge 1001 of the present embodiment is common to all the embodiments except the support member 1012.

The aerosol-forming base material 1010 is formed so that a long tobacco filling material 1020 is bundled along the length direction and wound around a sheet-shaped package 1025 to form a substantially cylindrical shape. Tobacco filling 1020 is formed from non-tobacco plants. However, the tobacco filling 1020 may be made of tobacco.

The tobacco filling 1020 is a sheet obtained by mixing an aerosol former that generates an aerosol, microcrystalline cellulose, an additive that adds flavor, a preservative, an adhesive, a thickener, etc. with a dried / crushed non-tobacco plant. It is formed by forming it into a shape and then cutting it so as to have a predetermined width and length. However, the tobacco filling 1020 may be formed in a different shape such as fine dust or granules.

The support member 1012 has a flow path 1012c that allows an air flow containing the aerosol generated in the aerosol-forming base material 1010 to flow to the filter 1014 side. The first end face 1012a of the support member 1012 abuts on the end face of the aerosol-forming substrate 1010, and the second end face 1012b of the support member 1012 abuts on the end face of the filter 1014. The support member 1012 circulates an air flow between the aerosol-forming base material 1010 and the filter 1014, and supports the aerosol-forming base material 1010 in the length direction. The filter 1014 is a sponge-like porous body and is formed in a cylindrical shape.

In the present embodiment, the heat-not-burn 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 base material 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 a usage pattern of the heat-not-burn tobacco cartridge 1001. The heat-not-burn tobacco cartridge 1001 is used by being attached to the heat-not-burn tobacco body 1002. The heat-not-burn tobacco body 1002 has an insertion portion 1051 into which the heat-not-burn 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 heating type tobacco cartridge 1001. The heating unit 1050 can generate an aerosol from the tobacco filling 1020 by generating heat while being inserted into the tobacco filling 1020. In this state, the user can suck the air flow containing the aerosol by sucking it from the filter 1014.

The support member 1012 will be described in detail. The support member 1012 is made of a resin material. Examples of the resin material forming the support member 1012 include those such as 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 and metal (aluminum and the like) having an increased cooling effect.

The support member 1030 according to the first embodiment will be described. 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 form both end faces along the longitudinal direction of the heat-not-burn tobacco cartridge 1001. The support member 1030 has a support portion 1031 provided so as to be inclined with respect to the central axis C1 of the heat-not-burn tobacco cartridge 1001 along the longitudinal direction of the heat-not-burn tobacco cartridge 1001, and laterally extending outward from the support portion 1031. It has an extension portion 1032. The lateral extending portion 1032 extends from the supporting 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 with respect to all of the X, Y, and Z directions in the figure.

The outer edge portion 1033 of the lateral extending portion 1032 is in contact with the packaging member 1016 of the heat-not-burn tobacco cartridge 1001 shown by the alternate long and short dash line in FIG. The four regions surrounded by the lateral extending portion 1032 and the packaging member 1016 form a flow path 1037 penetrating from the first end surface 1035 to the second end surface 1036 of the support member 1030, respectively, and serve as an aerosol forming group of the heated tobacco cartridge 1001. The airflow containing the aerosol generated from the material 1010 can be flowed to 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 including the aerosol generated from the aerosol forming base material 1010 becomes long, 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, a turbulent flow is generated in the air flow, which has the effect of making it uniform. Further, since the outer edge portion 1033 of the lateral extending portion 1032 in contact with the packaging member 1016 is inclined, the support of the packaging member 1016 is strengthened and the flow path 1037 is less likely to be crushed by an external force from the side. be able to.

The support member 1040 has four laterally extending portions 1042 whose outer edge portion 1043 is in contact with the packaging member 1016. The lateral extending portions 1042 are arranged so as to face four directions orthogonal to each other from the central axis C2 of the support member 1040. The lateral extension 1042 is connected by a support 1041 provided at an arbitrary position in the longitudinal direction of the support member 1040, and the lateral extension 1042 is not directly connected to each other.

The support portion 1041 is provided in the central portion 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 extending portion 1042 has a recess 1042a that opens in the central axis C2 direction of the support member 1040, and the four ends of the support portion 1041 are arranged and connected to the recess 1042a, respectively. The support portion 1041 is not limited to a rod shape, and may have another form such as a plate shape.

Also in the support member 1040, the four regions surrounded by the lateral extending portion 1042 and the packaging member 1016 serve as a flow path 1047 for flowing an air flow containing the aerosol generated from the aerosol forming base material 1010. The four lateral extending portions 1042 may each have a different form. Since the lateral extension 1042 is connected by the support 1041 that does not extend in the longitudinal direction, each shape can be designed relatively freely. Further, since the lateral extending portions 1042 are not directly connected to each other, a slight gap is generated between the flow paths 1047, and the air flow in each flow path 1047 is made uniform.

The support member 1060 according to the third embodiment will be described.

The support member 1390 of FIG. 35 (d) has a notch portion 1392a having a substantially rectangular cross-sectional shape, a notch portion 1392b having a substantially triangular cross-sectional shape, and a notch portion 1392c formed by a smooth curved surface, respectively. It has multiple positions at different positions in the circumferential direction.

As described above, 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 the air flow path. In each embodiment in which the notch is provided, the area of the solid portion of the support member is large, so that the support function of the aerosol-forming base material 1010 can be enhanced.

The support member 1400 according to the fourteenth embodiment will be described. FIG. 36 shows an end view of the support member 1400 of the 14th embodiment cut in a plane orthogonal to the central axis C1 of the heat-not-burn tobacco cartridge. The support member 1400 has five through-hole portions 1406 in the central portion and the peripheral portion.

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 adjusting 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 filter 1014 is sucked and the inside of the packaging member 1016 becomes in a negative pressure state, outside air is taken in through the packaging member 1016. The degree of taking in external air changes depending on the ventilation resistance of the packaging member 1016.

When the ventilation resistance of the packaging member 1016 is less than 30 kPa, the ventilation resistance is low, so that it is easy to take in outside air, and a mild taste can be obtained by combining with the air flow from the aerosol-forming base material 1010. 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 the middle range, and the balance with the air flow from the aerosol-forming base material 1010 can be improved by appropriately taking in the outside air. In this case, the porosity of the support member 1400 is preferably 30 to 70%.

When the ventilation resistance of the packaging member 1016 is 70 kPa or more, the ventilation resistance is high, so that it is difficult to take in outside air, and the airflow from the aerosol-forming base material 1010 becomes dominant, so that a strong and chewy taste can be obtained. 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 ventilation resistance (kPa) of the packaging member 1016 is B, it is desirable to satisfy any of the following relational expressions (1) to (4).
A × B = 1050 to 10500 (1)
A2 x B = 5000-25000 (2)
A3 x B = 160000-400000 (3)
A4 x B = 5,000,000 to 6500000 (4)

Although the embodiment of the present invention has been described above, the application of the present invention is not limited to the present embodiment and can be variously applied within the scope of the technical idea thereof. For example, in the present embodiment, only the support member 1012 is provided between the aerosol forming base material 1010 and the mouthpiece 1014, but another member such as a cooling member is provided between the support member 1012 and the mouthpiece 1014 mouthpiece 1014. It may be provided. Further, the number of lateral extending portions in each embodiment may be only one or may be plural.
