Description

TECHNICAL FIELD The present invention relates to a cartridge for a smoking device and a lid member.

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 heating type smoking implements, for example, smoking implements including a heating element and smoking implements including an induction heating element are known. A smoking device including a heating element is provided with a heating element in the shape of, for example, a blade, a rod, a pin, or a triangle, and the heating element is used by being inserted into a cartridge containing an aerosol-forming substrate. 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 covers everything from the lid member 11 to the mouthpiece 15.

The aerosol forming base material 12 is provided between the lid member 11 and the support member 14, and extends along the Y 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.

Aerosol-forming substrate 12 includes tobacco or non-tobacco plants. 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, and the susceptor 13 is exposed at one end E1 of the aerosol forming base material 12. ing. 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. 4, which will be described later), and an induced current flows through the susceptor 13, thereby inductively heating the susceptor 13. 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, and the like.

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 (for example, FIG. 5, which will be described later). By providing this lid member 11, one end E1 of the aerosol forming base material 12 is not exposed to the outside, so that the aerosol forming base material 12 can be protected.

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.

It is preferable that the lid member 11 is made of a non-porous material and 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 lid member 11 is provided with an opening 11M that penetrates the lid member 11 in the Y direction. A part of the aerosol forming base material 12 is exposed from this opening 11M, and gas flows into one end E1 of the aerosol forming base material 12 from the outside through the opening 11M. Gas is discharged to the outside of the smoking article cartridge 10. That is, by providing the opening 11M in the lid member 11, a gas flow path in the Y direction of the smoking article cartridge 10 is secured. The lid member 11 is provided with, for example, one opening 11M. Although the lid member 11 may be provided with a plurality of openings 11M, by using only one opening 11M, it becomes easier to protect the aerosol forming base material 12. Although it is desirable that the opening 11M penetrates the lid member 11 in the Y direction, the opening 11M does not need to penetrate the lid member 11 in the Y direction, and may be formed of a recess, for example.

The opening 11M is arranged, for example, in the center of the lid member 11 in the X direction and the Z direction (FIG. 2). The opening 11M has, for example, a circular plane (XZ plane) shape. The diameter of this circular opening 11M is, for example, larger than the size of the susceptor 13 in the X direction and the Z direction. For example, when the size of the susceptor 13 in the X direction is 1.8 mm and the size in the Z direction is 0.13 mm, the diameter of the opening 11M is 2.5 mm.

The opening 11M may be provided at a position facing the susceptor 13. Thereby, air flowing into one end E1 of the aerosol forming base material 12 from the outside through the opening 11M efficiently cools the susceptor 13, making it possible to suppress an excessive temperature rise in the susceptor 13.

3(A) and 3(B) each show the heating element 31 together with the lid member 11. The lid member 11 may be used in a cartridge that is inserted into a smoking device that includes this heating element 31. The heating element 31 is, for example, a metal having a blade shape, a rod shape, a pin shape, a triangular shape, or a polygonal shape, and is inserted into the aerosol forming substrate to heat it. For example, the size of the heating element 31 having a blade shape in the X direction is 8 mm or less, preferably 1 mm to 5 mm, and the size in the Z direction is 8 mm or less, preferably 0.1 mm to 3 mm. Preferably, the size in the Y direction is 20 mm or less. For example, the diameter of the heating element 31 having a rod shape, pin shape, or polygon shape is 8 mm or less, preferably 0.1 mm to 5 mm, and the size in the Y direction is 20 mm or less. The heating element 31 may have a shape such as a cylinder, a prism, a cone, or a pyramid, or may have a shape other than the above.

It is preferable that the opening 11M of the lid member 11 has a shape that allows the heating element 31 to pass therethrough. Specifically, it is preferable that the diameter of the opening 11M is larger than the size of the heating element 31 in the X direction and the Z direction. Alternatively, the opening 11M may be deformed to allow the heating element 31 to pass through. Thereby, the lid member 11 can also be used in a smoking implement cartridge for a smoking implement that includes a heating element (for example, the heating element 31). That is, the lid member 11 can be used in a cartridge (for example, the cartridge 10 for a smoking device) used in an induction heating type smoking device (smoking device 20 in FIG. 4, which will be described later), and a cartridge used in a smoking device including a heating element. It becomes possible to share the information with The opening 11M may be arranged at the center of the XZ plane of the lid member 11 (FIG. 3(A)), or may be arranged at a position away from the center (FIG. 3(B)).

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 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.

<How to use the smoking article cartridge 10>
FIG. 4 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 one end E1 of the aerosol forming base material 12 from outside the smoking article cartridge 10 through the opening 11M of the lid member 11. 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.

<Operations and effects of the lid member 11 and the smoking implement cartridge 10>
In the smoking article cartridge 10 of this embodiment, the lid member 11 made of a non-porous material covers one end E1 of the aerosol forming base material 12. As a result, one end E1 of the aerosol forming base material 12 is not exposed to the outside, so damage to the aerosol forming base material 12 due to, for example, physical contact or chemical contact with the one end E1 of the aerosol forming base material 12 is prevented. It can be suppressed. Therefore, the aerosol forming substrate 12 can be protected.

Moreover, this lid member 11 has one or more openings 11M. Thereby, gas flows into one end E1 of the aerosol forming base material 12 from the outside through this opening 11M, and gas is discharged from the one end E1 of the aerosol forming base material 12 to the outside. That is, a gas flow path within the smoking article cartridge 10 is secured. Therefore, in the smoking article cartridge 10 and the lid member 11, it is possible to protect the aerosol forming base material 12 while ensuring a gas flow path within the cartridge.

Furthermore, this opening 11M has a shape that allows a heating element (for example, the heating element 31 in FIGS. 3(A) and 3(B)) to pass through, so that smoking implements including a heating element and smoking implements including an induction heating element ( For example, it is possible to use the smoking article cartridge 10 for both smoking articles 20) in FIG. That is, it becomes possible to realize a hybrid cartridge.

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.

[Modification 1]
FIG. 5 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 membrane member 17 between one end E1 of the aerosol forming base material 12 and the lid member 11. 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.

The membrane member 17 is provided so as to close the opening 11M of the lid member 11. The membrane member 17 has, for example, a circular plane (XZ plane) shape, and the diameter of this circle is approximately the same as the diameter of the aerosol forming substrate 12. The membrane member 17 is, for example, a membrane having a thickness (size in the Y direction) of 5.0 mm or less, preferably 0.01 mm to 1.0 mm, and is configured to be permeable to gas.

[Modification 2]
FIG. 6 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.

[Modification 3]
FIG. 7 shows a cross-sectional (YZ cross-section) configuration of a smoking implement cartridge (smoking implement cartridge 10C) according to modification 3. In this smoking article cartridge 10C, the packaging member 16 is provided with a hole 16H. In this point, the smoking article cartridge 10C is different from the smoking article cartridge 10 (FIG. 1) of the above embodiment. Except for this point, the smoking article cartridge 10C according to Modification 3 has the same configuration as the smoking article cartridge 10 described in the above embodiment, and has the same effects.

The hole 16H is provided to penetrate the packaging member 16 in the thickness direction. This hole 16H reaches, for example, the aerosol forming base material 12. In other words, the holes 16H are provided in the packaging member 16 around the aerosol forming base material 12. The packaging member 16 may have a plurality of holes 16H, or may have one hole 16H. This hole 16H functions as a gas flow path within the cartridge. By providing the holes 16H in the packaging member 16 around the aerosol-forming base material 12, external air can be made to flow into the aerosol-forming base material 12 more efficiently. The hole 16H may be provided at other positions, such as around the support member 14.

In the smoking article cartridge 10C, the opening 11M of the lid member 11 and the hole 16H of the packaging member 16 function as a gas flow path within the cartridge. Specifically, the air flowing in from the opening 11M flows along the axial direction (Y direction) of the aerosol forming base material 12, and passes through the outer circumferential surface of the aerosol forming base material 12 from the hole 16H, and the air flows into the inside thereof. will flow in. As a result, the aerosol near the center axis of the aerosol forming base material 12 heated by the susceptor 13 and the aerosol on the outer peripheral side of the aerosol forming base material 12 having a lower temperature are mixed. Therefore, by using the smoking device cartridge 10C, a smoker can obtain a richer flavor and taste compared to the smoking device cartridge 10.

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. 4) 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.).

Furthermore, in the above-described embodiments and modifications, an example was illustrated in which the opening 11M of the lid member 11 was provided in the center of the lid member 11 (on the central axis of the aerosol forming base material 12) (FIG. 2), The opening 11M may be provided at other positions.

FIG. 8 shows another example of the arrangement of the openings 11M. It may be provided at a position away from the center of the lid member 11.

Furthermore, in the above-described embodiments and modified examples, an example in which the opening 11M of the lid member 11 has a circular planar shape has been described, but the planar shape of the opening 11M may be other shapes such as an ellipse or a quadrilateral.

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. 9 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.

Further, in the third modification described above, an example was described in which the opening 11M is provided in the lid member 11 and the hole 16H is provided in the packaging member 16. However, instead of providing the opening in the lid member 11, the packaging member 16 is A hole 16H may be provided.

FIG. 10 shows another example of the lid member 11. For example, the lid member 11 may not have an opening (the opening 11M in FIG. 1) as described above, and the packaging member 16 may be provided with a plurality of holes 16H. In this cartridge for a smoking article, the hole 16H ensures a gas flow path within the cartridge.

Further, in the above-described embodiments and modifications, an example was described in which the opening 11M penetrates the lid member 11 in the Y direction, but the opening 11M does not need to penetrate the lid member 11. For example, the opening 11M may be a recess provided in the surface of the lid member 11 on the aerosol forming base material 12 side. At this time, it becomes possible to suppress leakage of the constituent materials of the aerosol forming base material 12. For example, when the packaging member 16 is provided with a hole 16H (for example, FIGS. 7 and 10), there is a risk that the constituent material of the aerosol forming base material 12 may leak to the outside from the hole 16H. By providing the recess-shaped opening 11M in the lid member 11, it is possible to receive the constituent material of the aerosol forming base material 12 at the opening 11M before it leaks from the hole 16H, and this leakage can be suppressed.

Alternatively, the recess-shaped opening 11M may be provided on the side of the lid member 11 opposite to the aerosol-forming base material 12, that is, on the insertion side into a smoking tool (for example, the smoking tool 20 in FIG. 4). At this time, the smoking article cartridge 10 can be easily inserted into the smoking article. Specifically, the lid member 11 is deformed when the smoker presses the vicinity of the concave opening 11M, so even if the diameter of the insertion port of the smoking tool is small, the lid member 11 deforms and allows smoking. The device cartridge 10 can be easily inserted into a smoking device.
