Description

The present invention relates to cartridges for smoking devices.

In recent years, various tobacco products have become popular. Among these tobacco products, so-called heating type tobacco products can be heated without using a flame by attaching a cartridge containing tobacco components to a heating type smoking tool. Smokers can enjoy tobacco by inhaling the vaporized tobacco components through heating. Cartridges containing ingredients from plants other than tobacco are also becoming popular.

As a heating type smoking device, for example, a smoking device including an induction heating element is known. Smoking devices that include induction heating elements use cartridges that have a susceptor within an aerosol-forming substrate (for example, Patent Document 1). By induction heating the susceptor, the aerosol forming substrate is heated and an aerosol is generated.

<Configuration of smoking article cartridge 10>
The smoking article cartridge 10 includes, for example, a lid member 11, an aerosol forming base material 12, a susceptor 13, a support member 14, a mouthpiece 15, and a packaging member 16. The susceptor 13 is placed within the aerosol-forming substrate 12 . In the smoking article cartridge 10, a lid member 11, an aerosol forming base material 12 including a susceptor 13, a support member 14, and a mouthpiece 15 are provided in this order along the Y direction. The packaging member 16 is provided over the extending direction (Y direction) of the smoking article cartridge 10, and the packaging member 16 covers everything from the lid member 11 to the mouthpiece 15. Here, the packaging member 16 corresponds to a specific example of the first packaging member of the present invention.

The aerosol forming base material 12 is provided between the lid member 11 and the support member 14, and has an extending direction (Y direction) and a circumferential direction. This aerosol forming base material 12 is, for example, formed into a cylindrical shape and has one end E1 and the other end E2 in the Y direction. One end E1 of the aerosol forming base material 12 is covered with a lid member 11. The other end E2 of the aerosol forming base material 12 is in contact with the support member 14, for example.

FIG. 3 shows the configuration of the end surface (XZ end surface) on the one end E1 side of the aerosol forming base material 12. As shown in FIG. Although not shown, the end surface of the aerosol forming base material 12 on the other end E2 side also has a similar configuration. For example, the susceptor 13 is exposed on both end surfaces of the aerosol forming base material 12. The side surface (peripheral surface) of the cylindrical aerosol forming substrate 12 is covered with a packaging member 16 .

The aerosol-forming substrate 12 contains a tobacco plant or a non-tobacco plant as a raw material. Tobacco plants are, for example, tobacco leaves, tobacco stems, expanded tobacco or homogenized tobacco. A non-tobacco plant is a plant other than a tobacco plant. The aerosol forming substrate 12 includes leaves, pulp, seeds, roots (scaly roots, tuberous roots, etc.), stems, tubers, skins (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), and stems of non-tobacco plants. It is also preferable that it includes a portion such as a branch or a branch.

Here, "plant" means a biological category in contrast to animals. Plants here include not only organisms that have roots and live in a fixed location, such as grass and trees, but also algae such as microalgae and seaweed, and fungi such as mushrooms. .

The aerosol-forming substrate 12 may be, for example, dried and crushed non-tobacco plants, and an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives and binders or thickeners, etc., as appropriate. It is a powder or granular aggregate that is mixed and then crushed or classified. The aerosol forming base material 12 may be in the form of a paste. Further, the aerosol forming substrate 12 may be formed by forming a raw material containing a non-tobacco plant into a sheet shape and then cutting the sheet to have a predetermined width and length.

When the part of the non-tobacco plant is a leaf, the aerosol-forming substrate 12 can preferably be made of tea. This is because tea includes various types of tea plants, and even the same plant can produce different teas depending on the processing method. Specifically, for example, Japanese tea, black tea, tomorrow leaf tea, sweet tea, Jiaogulan tea, aloe tea, ginkgo biloba tea, oolong tea, turmeric tea, eulogna tea, eleuthero tea, plantain tea, persimmon leaf tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara Keimei tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, goji tea, soft leaf tea, black soybean tea, gennoshoko tea, genmaicha, burdock tea, comfrey tea, bifu tea , cherry blossom tea, saffron tea, shiitake tea, perilla tea, jasmine tea, ginger tea, horsetail tea, red scallion tea, Japanese japonica tea, buckwheat tea, ataranoki tea, dandelion tea, sweet tea, dokudami tea, duchu tea, nut bean tea, elderberry tea , rat glutinous tea, pearl barley tea, habu tea, loquat leaf tea, puerh tea, safflower tea, pine needle tea, yerba mate tea, barley tea, meguslin tea, mugwort tea, eucalyptus tea, Luohan tea, rooibos tea, and bitter melon tea. The aerosol forming base material 12 may be used used tea leaves after drinking. By using used tea leaves, you can reuse expensive tea and other items.

Furthermore, the aerosol-forming substrate 12 may be made of non-tobacco plant extracts, so-called extracts, processed products, and the like. Examples of the form of the extract include liquid, syrup, powder, granules, and solution.

The aerosol former contained in the aerosol forming base material 12 is, for example, glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate. , triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedioate or dimethyl tetradecanesanedionate. Among them, glycerin and propylene glycol are preferred.

The microcrystalline cellulose contained in the aerosol-forming base material 12 is formed by, for example, first producing α-cellulose from the pulp of a fibrous plant, and then partially depolymerizing this α-cellulose with an acid. do. In this microcrystalline cellulose, the soluble portion is removed from the cellulose, and the insoluble portion is crystallized. Microcrystalline cellulose may be a powder or a suspension dispersed in a solvent such as water. For dispersion in a solvent, for example, a high speed stirrer or a high pressure homogenizer can be used.

Preferably, the aerosol-forming substrate 12 contains a flavor additive. Examples of flavor additives include mint, cocoa, coffee, and black tea extracts, or catechin powder from tea extracts. The preservative contained in the aerosol-forming base material 12 is preferably a preservative used for food products, such as sorbic acid, potassium sorbate, benzoic acid, or sodium benzoate.

Aerosol-forming substrate 12 may contain menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone). By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed and the flavor of menthol can be maintained for a long period of time. Here, menthol is not limited to those obtained from natural products, and may be synthetic products. The aerosol-forming substrate 12 may contain peppermint, mint, peppermint oil, or other materials containing menthol.

The flavor additive may be provided in the mouthpiece 15. For example, the wall of the mouthpiece 15 may be impregnated with a flavor additive, or a capsule containing the flavor additive may be embedded in the wall of the mouthpiece 15. Alternatively, a capsule containing a flavor additive may be placed between the mouthpiece 15 and the aerosol-forming substrate 12. When the flavor additive is encapsulated in a capsule, when the smoker presses the capsule with his/her finger, the capsule is destroyed and the aromatic components of the flavor additive are volatilized. Therefore, the smoker can generate aroma components at a timing of his/her preference. The encapsulated flavor additive may be provided on the aerosol-forming substrate 12 or on the support member 14.

The binder or thickener contained in the aerosol-forming substrate 12 is, for example, guar gum, xanthan gum, rubber, cellulose binder, organic acid, conjugated base salt of an organic acid, polysaccharide, and combinations thereof. Gums include, for example, gum arabic and locust bean gum. Cellulose binders include, for example, hydroxypropylcellulose, carboxymethylcellulose, hydroxyethylcellulose, methylcellulose, and ethylcellulose. Conjugate base salts of organic acids include, for example, sodium alginate and sodium carboxymethylcellulose. Polysaccharides include caranagin, agar and pectin.

The susceptor 13 provided within the aerosol forming base material 12 is, for example, a plate-like member having a rectangular plane (XY plane) shape. The susceptor 13 is made up of, for example, a single plate-like member. The susceptor 13 is provided, for example, along the central axis of the aerosol-forming base material 12, and is arranged at the center of the aerosol-forming base material 12 in the XZ plane (FIG. 2). The size of the susceptor 13 in the Y direction (hereinafter referred to as length) is approximately the same as the size of the aerosol forming base material 12 in the Y direction. The length of the susceptor 13 is, for example, 12 mm to 18 mm. The width (size in the X direction) of the susceptor 13 is, for example, 1.0 mm to 2.5 mm. The thickness (size in the Z direction) of the susceptor 13 is, for example, 0.11 to 0.63 mm.

The susceptor 13 is configured to be capable of induction heating. The susceptor 13 is inserted into a smoking tool (for example, the smoking tool 20 in FIG. 8 described below), and an induced current flows through the susceptor 13, so that the susceptor 13 is heated by induction. As a result, the aerosol forming base material 12 is heated to a sufficient temperature, and an aerosol is generated.

The susceptor 13 is made of, for example, an alloy containing a plurality of magnetic metal materials. The plurality of magnetic metal materials have different Curie temperatures. Magnetic metal materials include ferromagnetic metal materials, paramagnetic metal materials, and diamagnetic metal materials. Ferromagnetic metal materials are materials that are strongly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and remain strong magnetically even when the external magnetic field is reduced to zero, such as iron, nickel, cobalt, and ferritic stainless steel. It is. The relative magnetic permeability of ferromagnetic metal materials is extremely larger than 1. For example, the relative magnetic permeability of iron is about 5000, the relative magnetic permeability of nickel is about 600, the relative magnetic permeability of cobalt is about 250, and the relative magnetic permeability of ferritic stainless steel is about 250. The relative magnetic permeability is about 1000 to 1800.

Paramagnetic metal materials are materials that become weakly magnetic in the same direction as the external magnetic field when an external magnetic field is applied, and cease to be magnetic when the external magnetic field is reduced to zero, such as aluminum, chromium, platinum, and manganese. The relative magnetic permeability of paramagnetic metal materials is slightly larger than 1. For example, the relative magnetic permeability of aluminum is about 1.000021, the relative magnetic permeability of platinum is about 1.000265, and the relative magnetic permeability of manganese is 1.000830. That's about it.

Diamagnetic metal materials are materials that are weakly magnetized in the opposite direction to the external magnetic field when an external magnetic field is applied, and cease to be magnetic when the external magnetic field is reduced to zero, such as copper, graphite, and bismuth. The relative magnetic permeability of diamagnetic metal materials is slightly smaller than 1. For example, the relative magnetic permeability of copper is about 0.999990, the relative magnetic permeability of graphite is about 0.99980, and the relative magnetic permeability of bismuth is about 0.99990. It is about 999834.

When an alternating magnetic field is generated in a ferromagnetic metal material, an induced current flows and Joule heat is generated, and heat (hysteresis loss) is generated due to friction and vibration between molecules. Therefore, ferromagnetic metal materials are more easily induction heated than paramagnetic metal materials and diamagnetic metal materials. For this reason, it is preferable that the susceptor 13 includes a plurality of ferromagnetic metal materials having mutually different Curie temperatures.

Further, ferromagnetic metal materials have a high Curie temperature; for example, the Curie temperature of nickel is about 358°C. Therefore, even if the smoking article cartridge 10 is heated to a high temperature of, for example, 200° C., the susceptor 13 will not reach the Curie temperature, and its ferromagnetic properties will be maintained. Therefore, the aerosol forming base material 12 can be stably heated. The susceptor 13 is made of an alloy containing, for example, nickel, chromium, aluminum, silicon, manganese, carbon, phosphorus, sulfur, iron, and the like. The susceptor 13 may be made of an alloy containing iron and nickel, or may be made of an alloy containing iron and cobalt.

The susceptor 13 may be made of an alloy containing a ferromagnetic metal material and a paramagnetic metal material, such as an alloy containing iron, chromium, and aluminum. The susceptor 13 may be made of an alloy containing a ferromagnetic metal material and a diamagnetic metal material, such as an alloy containing iron and copper.

The support member 14 provided between the aerosol forming base material 12 and the mouthpiece 15 supports the other end E2 of the aerosol forming base material 12 and plays a role of cooling the aerosol generated in the aerosol forming base material 12. ing. The support member 14 is in contact with the other end E2 of the aerosol forming base material 12, for example. The support member 14 is, for example, formed into a cylindrical shape having approximately the same diameter as the aerosol forming base material 12, and its side surface is in contact with the packaging member 16. Thereby, the position of the support member 14 in the Y direction is fixed. The side surface of the support member 14 may be adhered to the packaging member 16.

This support member 14 is provided with a flow path 14P extending in the Y direction. The flow path 14P is configured, for example, by a through hole that penetrates the support member 14 in the Y direction. Gas passes between the aerosol forming base material 12 and the mouthpiece 15 in the Y direction via this flow path 14P.

The support member 14 is, for example, an assembly of a plurality of cylindrical members, and a flow path 14P is configured by a cavity of each cylindrical member. That is, the support member 14 is provided with a plurality of channels 14P. By configuring the support member 14 with a plurality of cylindrical members, the surface area of the support member 14 becomes large, and it becomes possible to enhance the cooling function. The support member 14 may be composed of one cylindrical member. The size of the support member 14 is, for example, an outer diameter of 4.0 mm to 7.5 mm, and a length in the Y direction (length along the central axis) of 50 mm or less. Note that the support member 14 may have a size and shape different from those exemplified above depending on its function, configuration, etc.

It is preferable that the support member 14 is made of a heat-resistant material. Examples of heat-resistant materials include rubber-based materials such as silicone rubber. For example, the support member 14 can be formed from a plurality of cylindrical members made of rolled silicone rubber sheets. By constructing the support member 14 from a heat-resistant material, the support member 14 can be provided adjacent to the aerosol-forming substrate 12. The support member 14 may be made of a paper-based material, a resin-based material, a metal-based material, or the like in addition to the above-mentioned rubber-based material, or may be made of a sheet of these materials. As the paper-based material, for example, paper or cardboard can be used, and as the resin-based material, a polymer or the like can be used.

The support member 14 may be constituted by one cylindrical member, and the flow path 14P may be formed by providing a through hole in this cylindrical member. The cylindrical member constituting the support member 14 includes, for example, glass, ceramic, or a heat-resistant resin material.

The mouthpiece 15 is provided in contact with the support member 14 and is connected to the other end E2 of the aerosol forming base material 12 via the support member 14. This mouthpiece 15 constitutes the other end in the Y direction of the smoking article cartridge 10, that is, the mouthpiece. The mouthpiece 15 is made of, for example, paper. Mouthpiece 15 may include a filter for removing particulates, such as a cellulose acetate filter. This filter filters out water vapor generated in the aerosol-forming substrate 12 and part of the fine particles in the aerosol.

The lid member 11, which constitutes the end opposite to the mouthpiece 15, covers one end E1 of the aerosol forming base material 12. Here, "covering one end E1 of the aerosol-forming base material 12" refers to a state in which the lid member 11 exists on an extension of one end E1 of the aerosol-forming base material 12 in the Y direction, and the lid member 11 covers the aerosol-forming base material 12. The lid member 11 may be in contact with one end E1 of the forming base material 12 (FIG. 1), or the lid member 11 may be provided apart from the one end E1 of the aerosol forming base material 12 (not shown). For example, the lid member 11 covers the entire surface of one end E1 of the aerosol forming base material 12. By providing this lid member 11, one end of the cylindrical smoking device cartridge 10 is closed, so that the constituent materials of the aerosol forming base material 12 and the susceptor 13 are prevented from forming into the smoking device due to impact or the like. cartridge 10 can be prevented from coming out.

The lid member 11 is constituted by, for example, a circular plate-like member having approximately the same diameter as the diameter of the aerosol forming substrate 12. The circumferential surface of the lid member 11 is in contact with the packaging member 16. Thereby, the position of the lid member 11 in the Y direction is fixed, and the positions of the aerosol forming base material 12 and the susceptor 13 between the lid member 11 and the support member 14 are maintained. The circumferential surface of the lid member 11 may be adhered to the packaging member 16.

The lid member 11 is made of a non-porous material and blocks the flow of gas through one end of the smoking cartridge 10. It is preferable that the lid member 11 has heat resistance. Examples of heat-resistant non-porous materials include rubber-based materials, resin-based materials, metal-based materials, and paper-based materials, and the lid member 11 includes at least one of these materials. Examples of rubber-based materials include silicone rubber, examples of resin-based materials include polypropylene, polyethylene, acrylic, vinyl chloride, fluororesin, PET (polyethyleneterephthalate), and PTFE (polytetrafluoroethylene), and metal-based materials include , for example, aluminum (Al), iron (Fe), brass (Cu--Zn), etc. Examples of paper-based materials include compression-molded paper and cardboard.

The packaging member 16 covers the lid member 11, the aerosol forming base material 12, the support member 14, and the mouthpiece 15 in the circumferential direction. For example, the packaging member 16 can be formed by winding a sheet-like member such as paper into a cylindrical shape in the circumferential direction of the lid member 11, the aerosol forming base material 12, the support member 14, and the mouthpiece 15. The packaging member 16 may be formed using a plurality of sheet-like members.

In this embodiment, this packaging member 16 has an opening 16M (first opening). For example, the packaging member 16 has a plurality of openings 16M, and the plurality of openings 16M are arranged at equal intervals over the entire surface of the packaging member 16. For example, a portion of each of the lid member 11, aerosol forming base material 12, support member 14, and mouthpiece 15 is exposed from the opening 16M. Gas flows into the aerosol forming base material 12 from the outside through the plurality of openings 16M, and gas flows out from the smoking article cartridge 10 to the outside through the plurality of openings 16M. That is, the plurality of openings 16M provided in the packaging member 16 ensure a gas flow path within the smoking article cartridge 10.

The plurality of openings 16M have, for example, a circular planar shape (FIG. 2). The plurality of openings 16M have, for example, the same diameter.

4, 5, 6, and 7 each show other examples of the opening 16M. The plurality of openings 16M may have a planar shape other than a circle, for example, a quadrangular planar shape (FIG. 4). Although not shown, the plurality of openings 16M may have other polygonal planar shapes such as triangles, pentagons, and hexagons, or may have elliptical planar shapes.

The plurality of openings 16M may be selectively arranged in some regions of the packaging member 16 (FIG. 5). It is preferable that the plurality of openings 16M be provided in a region covering the aerosol forming base material 12 (FIG. 6). In other words, the packaging member 16 preferably has an opening 16M that exposes a portion of the aerosol forming base material 12. This allows external air to flow into the aerosol forming base material 12 more efficiently.

The sizes of the plurality of openings 16M provided in the packaging member 16 may be different from each other (FIG. 7). For example, the size of the opening 16M in some areas of the packaging member 16 may be larger than the size of the opening 16M in other areas. Although not shown, the packaging member 16 may be provided with a plurality of openings 16M non-uniformly. For example, in some areas of the packaging member 16, the openings 16M have a higher density than in other areas. may be provided.

<How to use the smoking article cartridge 10>
FIG. 8 shows an example of how to use the smoking article cartridge 10. The smoking implement cartridge 10 is used by being attached to an induction heating type smoking implement 20. The smoking device 20 includes an insertion port 21, a coil 22, and a circuit board (not shown).

The insertion port 21 is a hole for inserting the smoking article cartridge 10 into the smoking article 20, and is provided extending from the end of the smoking article 20 in a predetermined direction. The smoking implement cartridge 10 is inserted into the smoking implement 20 through this insertion port 21. The coil 22 is provided so as to circumferentially surround the smoking tool cartridge 10 inserted into the smoking tool 20. The circuit board includes a CPU that controls the supply of alternating current to the coil 22.

When a smoker inserts the smoking article cartridge 10 into the insertion port 21 and then turns on the smoking article 20, an alternating current is supplied to the coil 22 by the circuit board. As a result, an induced current flows through the susceptor 13 provided within the aerosol forming base material 12, and heat resulting from Joule heat and hysteresis loss is generated in the susceptor 13. That is, the susceptor 13 is heated by induction. The heat transferred from the induction-heated susceptor 13 heats the aerosol-forming base material 12 around the susceptor 13 and generates an aerosol.

At this time, when the smoker holds the mouthpiece 15 in his/her mouth and inhales, air flows into the aerosol forming base material 12 from outside the smoking article cartridge 10 through the opening 16M of the packaging member 16. Due to this inflow of air, the aerosol generated by the aerosol-forming base material 12 flows into the smoker's mouth via the flow path 14P of the support member 14 and the mouthpiece 15.

<Actions and effects of the smoking implement cartridge 10>
In the smoking article cartridge 10 of this embodiment, the packaging member 16 that covers the aerosol forming base material 12 in the circumferential direction has an opening 16M. Thereby, gas flows into the smoking article cartridge 10 from the outside through the opening 16M. Therefore, it is possible to secure a gas flow path within the smoking article cartridge 10.

Furthermore, in the packaging member 16, the number, position, shape, size, etc. of the openings 16M can be easily adjusted. Therefore, the opening 16M can be adjusted according to the specifications of the smoking article cartridge 10 and the smoking article 20, and a gas flow path suitable for each specification can be secured. For example, the opening 16M can be adjusted according to the position of the susceptor 13, heating temperature, etc.

In addition, by providing the opening 16M over the entire circumference of the aerosol forming base 12, air can flow into the aerosol forming base 12 from the entire circumferential area of the aerosol forming base 12. This promotes heating of the susceptor 13 more efficiently, allowing the smoker to enjoy a stronger smoking sensation and a deeper taste of tobacco plants or non-tobacco plants.

Further, since the smoking article cartridge 10 has a lid member 11 that covers one end E1 of the aerosol forming base material 12, one end of the smoking article cartridge 10 is closed by the lid member 11. This can prevent the constituent materials of the aerosol-forming substrate 12 and the susceptor 13 from coming out of the smoking device cartridge 10 due to impact or the like. For example, when a smoker takes out the smoking implement cartridge 10 from the smoking implement 20, the constituent material of the aerosol forming base material 12 and the susceptor 13 are prevented from remaining in the smoking implement 20, and the smoking implement cartridge 10 and the smoking implement are prevented from remaining in the smoking implement 20. 20 durability can be increased.

Hereinafter, a modification of the smoking implement cartridge described in the above embodiment will be described. Note that, in order to avoid duplication of explanation, detailed explanations of the same structures as those of the smoking implement cartridge described in the above embodiments will be omitted below.

FIG. 9 shows a cross-sectional (YZ cross-section) configuration of a smoking implement cartridge (smoking implement cartridge 10A) according to Modification 1. This smoking article cartridge 10A has a packaging member 17 between the packaging member 16 and the aerosol forming base material 12. In this point, the smoking article cartridge 10A is different from the smoking article cartridge 10 (FIG. 1) of the above embodiment. Except for this point, the smoking article cartridge 10A according to Modification 1 has the same configuration as the smoking article cartridge 10 described in the above embodiment, and has the same effects. Here, the packaging member 17 corresponds to a specific example of the second packaging member of the present invention.

The packaging member 17 covers the aerosol forming base material 12 in the circumferential direction. The packaging member 16 covers the aerosol forming base material 12 with the packaging member 17 in between. In other words, the packaging member 17 covers the aerosol-forming base material 12 , and the packaging member 16 covers the aerosol-forming base material 12 together with the packaging member 17 . The packaging member 17 is made of a sheet-like member such as paper.

The packaging member 17 has, for example, a plurality of openings 17M (second openings). The plurality of openings 17M are provided, for example, over the entire surface of the packaging member 17. The plurality of openings 17M have, for example, a circular planar shape. The opening 17M may have other planar shapes such as a polygon and an ellipse. In the smoking article cartridge 10A, gas flows into the aerosol-forming base material 12 from the outside through the openings 16M and 17M, and gas flows out from the aerosol-forming base material 12 to the outside through the openings 16M and 17M. do. The opening 17M may be provided at a position overlapping the opening 16M, or may be provided at a position shifted from the opening 16M. The opening 17M may have the same size as the opening 16M, or may have a different size from the opening 16M. The openings 17M may be provided at the same pitch as the openings 16M, or may be provided at a different pitch from the openings 16M.

[Modification 2]
FIG. 10 shows a cross-sectional (YZ cross-section) configuration of a smoking implement cartridge (smoking implement cartridge 10B) according to modification 2. This smoking article cartridge 10B has a lid member 11, an aerosol forming base material 12 including a susceptor 13, and a mouthpiece 15 in this order along the Y direction. Piece 15 is in contact. That is, the smoking article cartridge 10B does not have a support member (support member 14 in FIG. 1). In this point, the smoking article cartridge 10B differs from the smoking article cartridge 10 (FIG. 1) of the above embodiment. Except for this point, the smoking article cartridge 10B according to the second modification has the same configuration as the smoking article cartridge 10 described in the above embodiment, and has the same effects.

In the smoking article cartridge 10B, the aerosol forming base material 12 is supported by the packaging member 16. In other words, by using the packaging member 16 that can support the aerosol forming substrate 12, it is possible to omit the support member. Since such a smoking article cartridge 10B is not provided with a support member, it is possible to reduce the number of parts and reduce costs.

The present invention is not limited to the embodiments described above, and can be variously modified within the scope of the claims.

For example, in the above-described embodiments and modifications, the smoking implement cartridge 10 used in the induction heating type smoking implement 20 (FIG. 8) was explained as an example, but the smoking implement cartridge of the present invention May be used in smoking devices including bodies. That is, the smoking article cartridge of the present invention does not need to have a susceptor (the susceptor 13 shown in FIG. 1, etc.).

Further, in the above-described embodiments and modifications, the specific configuration of the smoking implement cartridge 10 has been described, but the smoking implement cartridge 10 may not have all of the above configurations, or may have other configurations. It may have the following configuration. For example, the smoking article cartridge 10 does not need to have the lid member 11. Alternatively, the lid member 11 may have air permeability. Specifically, the lid member 11 may be made of a porous material, and the lid member 11 may be provided with holes.

Further, in the above-described embodiment, an example in which the susceptor 13 is provided on the central axis of the aerosol forming base material 12 is illustrated (FIG. 3), but the susceptor 13 may be provided at another position.

FIG. 11 shows another example of the arrangement of the susceptor 13. The susceptor 13 may be provided at a position off the central axis of the aerosol forming base material 12.

Furthermore, in the above-described embodiment, the smoking implement cartridge 10 has one susceptor 13 (see FIG. 1, etc.), but the smoking implement cartridge 10 has a plurality of susceptors 13. It's okay.

Further, in the above-described embodiment, an example in which the susceptor 13 is a plate-like member has been described, but the susceptor 13 may have another shape. For example, the susceptor 13 may be made of a particulate member.

Furthermore, in the above-described embodiments and modified examples, the packaging member 16 covers all of the lid member 11, the aerosol forming base material 12, the support member 14, and the mouthpiece 15 (for example, as shown in FIG. 1). , a portion of the lid member 11, the aerosol forming base material 12, the support member 14, and the mouthpiece 15 may be exposed from the packaging member 16.

FIG. 12 shows another example of covering with the packaging member 16. For example, a portion of the lid member 11 may protrude from the packaging member 16 and be exposed from the packaging member 16 in this way.

Furthermore, in the above-described embodiments and modifications, the packaging member 16 corresponds to a specific example of the first packaging member of the present invention, but the packaging member 17 is one of the first packaging members of the present invention. It may correspond to a specific example.
