<Structure of Smoking Article Cartridge 10>
The smoking device cartridge 10 has, for example, a lid member 11 , an aerosol-forming substrate 12 , a susceptor 13 , a support member 14 , a mouthpiece 15 and a packaging member 16 . A susceptor 13 is positioned within the aerosol-forming substrate 12 . In the smoking implement cartridge 10, a lid member 11, an aerosol-forming substrate 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 implement cartridge 10 , and covers the area from the lid member 11 to the mouthpiece 15 with the packaging member 16 .

The aerosol-forming substrate 12 is provided between the lid member 11 and the support member 14 and extends along the Y direction. The aerosol-forming substrate 12 is, for example, shaped like a cylinder and has one end E1 and the other end E2 in the Y direction. One end E<b>1 of the aerosol-forming substrate 12 is covered with a lid member 11 . The other end E2 of the aerosol-forming substrate 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 or homogenized tobacco, and the like. Non-tobacco plants are plants other than tobacco plants. The aerosol-forming substrate 12 includes non-tobacco plant leaves, pulp, seeds, roots (scales, tubers, etc.), stems, tubers, skins (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), stems, etc. Alternatively, it preferably contains a part such as a branch.

As used herein, the term "plant" refers to a biological division as opposed to animals. Plants here include algae such as microalgae and seaweeds, fungi such as mushrooms, etc., in addition to living organisms such as grasses and trees that have roots and live in fixed places. .

The aerosol-forming substrate 12 is, for example, dried and pulverized non-tobacco plants optionally mixed with an aerosol former to generate an aerosol, microcrystalline cellulose, flavor-adding additives, preservatives and binders or thickeners, and the like. After mixing, it is a powdery or granular aggregate that is pulverized or classified. The aerosol-forming substrate 12 may be pasty. Alternatively, the aerosol-forming substrate 12 may be formed by forming a raw material containing a non-tobacco plant into a sheet, and then cutting the sheet to have a predetermined width and length.

When the non-tobacco plant parts are leaves, the aerosol-forming substrate 12 can preferably be 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, Angelica keiskei tea, sweet tea, Gynostemma tea, aloe tea, ginkgo biloba tea, oolong tea, turmeric tea, oak tea, eleuthero tea, plantain tea, persimmon tea, persimmon leaf tea, Chamomile tea, chamomile tea, Kawahara tea, quince tea, chrysanthemum tea, gymnema tea, guava tea, wolfberry tea, soft leaf tea, black soybean tea, gennoshoko tea, brown rice tea, burdock tea, comfrey tea, bifu tea , cherry blossom tea, saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, ginger tea, horsetail tea, sekisho tea, assembly tea, buckwheat tea, taranogi tea, dandelion tea, sugar bean tea, dokudami tea, eucommia tea, soybean tea, elderberry tea , mouse wax tea, pigeon barley tea, habu tea, loquat leaf tea, pu-erh tea, safflower tea, pine needle tea, mate tea, barley tea, megusurinoki tea, mugwort tea, eucalyptus tea, monk fruit tea, rooibos tea and bitter gourd tea. Used tea leaves after drinking may be used as the aerosol-forming substrate 12 . Expensive tea can be reused and effectively utilized by using used tea leaves.

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

Aerosol formers contained in the aerosol-forming substrate 12 include, 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 tetradecanedioate. Among them, glycerin and propylene glycol are preferred.

The microcrystalline cellulose contained in the aerosol-forming substrate 12 is formed, for example, by first producing α-cellulose from fibrous plant pulp and then partially depolymerizing the α-cellulose with acid. do. In this microcrystalline cellulose, the soluble portion has been removed from the cellulose and the insoluble portion has 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 high-pressure homogenizer can be used.

The aerosol-forming substrate 12 preferably contains flavor additives. Flavor additives include, for example, mint, cocoa, coffee, black tea extract, or catechin powder of tea extract. The preservative contained in the aerosol-forming substrate 12 is preferably a preservative used in food products, such as sorbic acid, potassium sorbate, benzoic acid or sodium benzoate.

The 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 mint, mint, peppermint oil, and others containing menthol.

The flavor additive may be provided on the mouthpiece 15 . For example, the walls of mouthpiece 15 may be impregnated with a flavor additive, or capsules containing flavor additives may be embedded in the walls of mouthpiece 15 . Alternatively, between mouthpiece 15 and aerosol-forming substrate 12 a capsule containing a flavoring agent may be placed. When the flavor additive is enclosed in a capsule, a smoker's finger pressure on the capsule breaks the capsule and volatilizes the flavor additive's aromatic component. Therefore, the smoker can generate the aromatic component at his/her desired timing. The encapsulated flavor additive may be provided on the aerosol-forming substrate 12 and may be provided on the support member 14 .

Binders or thickeners included in the aerosol-forming substrate 12 are, for example, guar gums, xanthan gums, gums, cellulose binders, organic acids, conjugated base salts of organic acids, polysaccharides, 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 in the aerosol-forming substrate 12 is, for example, a plate-like member having a rectangular plane (XY plane) shape. The susceptor 13 is composed of, for example, a single plate-like member. The susceptor 13 is provided, for example, along the central axis of the aerosol-forming substrate 12, and arranged in the central portion of the aerosol-forming substrate 12 in the XZ plane (FIG. 2). The size of the susceptor 13 in the Y direction (hereinafter referred to as length) is substantially the same as the size in the Y direction of the aerosol-forming substrate 12, and the susceptor 13 is exposed at one end E1 of the aerosol-forming substrate 12. ing. Susceptor 13 has a length of, 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 induction-heatable. The susceptor 13 is inserted into a smoking article (for example, a smoking article 20 shown in FIG. 4 which will be described later), and an induced current flows through the susceptor 13 to heat it by induction. This heats the aerosol-forming substrate 12 to a sufficient temperature to generate an aerosol.

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 metallic materials include ferromagnetic metallic materials, paramagnetic metallic materials and diamagnetic metallic materials. Ferromagnetic metal materials are materials that strongly retain magnetism in the same direction as the external magnetic field when an external magnetic field is applied, and remain strong magnetism even when the external magnetic field is zero. Examples include iron, nickel, cobalt, and ferritic stainless steel. is. The relative magnetic permeability of ferromagnetic metal materials is much greater than 1. For example, iron has a relative magnetic permeability of about 5000, nickel has a relative magnetic permeability of about 600, cobalt has a relative magnetic permeability of about 250, and ferritic stainless steel has a relative magnetic permeability of about 250. Relative permeability is about 1000-1800.

A paramagnetic metal material is a material that becomes weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and becomes non-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 greater than 1. For example, aluminum has a relative magnetic permeability of about 1.000021, platinum has a relative magnetic permeability of about 1.000265, and manganese has a relative magnetic permeability of 1.000830. degree.

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

In a ferromagnetic metal material, when an alternating magnetic field is generated, 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. Therefore, the susceptor 13 preferably contains a plurality of ferromagnetic metal materials having different Curie temperatures.

In addition, ferromagnetic metal materials have a high Curie temperature. For example, the Curie temperature of nickel is about 358.degree. Therefore, even if the smoking device cartridge 10 is heated to a high temperature of 200° C., for example, the susceptor 13 does not reach the Curie temperature, and the properties of the ferromagnetic material are maintained. Therefore, the aerosol-forming substrate 12 can be stably heated. 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 composed of an alloy containing iron and nickel, or may be composed of an alloy containing iron and cobalt.

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

The support member 14 provided between the aerosol-forming substrate 12 and the mouthpiece 15 supports the other end E2 of the aerosol-forming substrate 12 and also serves to cool the aerosol generated by the aerosol-forming substrate 12. ing. The support member 14 is in contact with the other end E2 of the aerosol-forming substrate 12, for example. The support member 14 is, for example, shaped like a cylinder having a diameter approximately the same as the diameter of the aerosol-forming substrate 12 and abutting the packaging member 16 on its side. Thereby, the position of the support member 14 in the Y direction is fixed. The sides of the support member 14 may be adhered to the packaging member 16 .

The support member 14 is provided with a channel 14P extending in the Y direction. The flow path 14P is configured by, for example, a through-hole passing through the support member 14 in the Y direction. Gas passes between the aerosol-forming substrate 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 tubular members, and the passage 14P is configured by the cavity of each tubular member. That is, the support member 14 is provided with a plurality of flow paths 14P. By constructing the support member 14 with a plurality of cylindrical members, the surface area of the support member 14 is increased and the cooling function can be enhanced. 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 illustrated above, depending on its function, configuration, and the like.

The support member 14 is preferably made of a heat-resistant material. Examples of heat-resistant materials include rubber-based materials such as silicon rubber. For example, the support member 14 can be formed of a plurality of tubular members formed by rolling a silicon rubber sheet. Constructing the support member 14 from a heat-resistant material allows the support member 14 to 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 rubber-based material described above, or may be configured using a sheet of these materials. For example, paper and cardboard can be used as the paper-based material, and polymers and the like can be used as the resin-based material.

The support member 14 may be composed of one columnar member, and the channel 14P may be formed by providing a through hole in this columnar member. The columnar member that constitutes the support member 14 contains, for example, glass, ceramic, or a heat-resistant resin material.

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

A lid member 11 forming an end opposite to the mouthpiece 15 covers one end E1 of the aerosol-forming substrate 12 . Here, “covering one end E1 of the aerosol-forming substrate 12” means that the lid member 11 exists on the extension of the one end E1 of the aerosol-forming substrate 12 in the Y direction. It 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 described later). By providing the lid member 11, the aerosol-forming substrate 12 can be protected because the one end E1 of the aerosol-forming substrate 12 is not exposed to the outside.

Lid member 11 is configured by, for example, a circular plate-like member having approximately the same diameter as aerosol-forming substrate 12 . A 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 substrate 12 and the susceptor 13 between the lid member 11 and the support member 14 are maintained. A circumferential surface of the lid member 11 may be adhered to the packaging member 16 .

The lid member 11 is preferably made of a non-porous material and has heat resistance. Heat-resistant non-porous materials include, for example, rubber-based materials, resin-based materials, metal-based materials, and paper-based materials. Lid member 11 includes at least one of these materials. Examples of rubber-based materials include silicone rubber and the like; examples of resin-based materials include polypropylene, polyethylene, acrylic, vinyl chloride, fluororesin, PET (Polyethyleneterephthalate), PTFE (polytetrafluoroethylene), and the like; and metal-based materials include , such as aluminum (Al), iron (Fe) and brass (Cu—Zn). Paper-based materials include, for example, compression-molded paper and cardboard.

The lid member 11 is provided with an opening 11M passing through the lid member 11 in the Y direction. A part of the aerosol-forming substrate 12 is exposed from the opening 11M, and gas flows into the one end E1 of the aerosol-forming substrate 12 from the outside through the opening 11M. The gas is discharged to the outside of the smoking implement cartridge 10 from the . That is, by providing the opening 11</b>M in the lid member 11 , a gas flow path in the Y direction of the smoking implement cartridge 10 is ensured. Lid member 11 is provided with, for example, one opening 11M. A plurality of openings 11M may be provided in the lid member 11, but by providing one opening 11M, the aerosol-forming substrate 12 can be easily protected. The opening 11M preferably penetrates the lid member 11 in the Y direction, but the opening 11M does not have to penetrate the lid member 11 in the Y direction, and may be configured as a recess, for example.

The opening 11M is arranged, for example, in the central portion 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 dimensions of the susceptor 13 in the X and Z directions. 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 11</b>M may be provided at a position facing the susceptor 13 . As a result, the air that has flowed into the one end E1 of the aerosol-forming base material 12 from the outside through the opening 11M can efficiently cool the susceptor 13 and suppress an excessive temperature rise of the susceptor 13 .

FIGS. 3A and 3B each show the heating element 31 together with the lid member 11. FIG. The lid member 11 may be used for a cartridge that is inserted into a smoking article that includes this heating element 31 . The heating element 31 is, for example, a metal having a blade-shaped, rod-shaped, pin-shaped, triangular or 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 rod-shaped, pin-shaped, or polygonal heating element 31 has a diameter of 8 mm or less, preferably 0.1 mm to 5 mm, and a size in the Y direction of 20 mm or less. The heating element 31 may have a shape such as a column, a prism, a cone, a pyramid, or the like, or may have a shape other than the above.

The opening 11M of the lid member 11 preferably 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. This makes it possible to use the lid member 11 also for a smoking implement cartridge containing a heating element (for example, the heating element 31). That is, the lid member 11 is used for a cartridge (for example, a smoking device cartridge 10) used for an induction heating type smoking device (a smoking device 20 shown in FIG. 4 which will be described later) and a cartridge used for a smoking device including a heating element. It is possible to share with The opening 11M may be arranged in the central portion of the XZ plane of the lid member 11 (FIG. 3A), or may be arranged in a position away from the central portion (FIG. 3B).

The packaging member 16 circumferentially covers the lid member 11 , the aerosol-forming substrate 12 , the support member 14 and the mouthpiece 15 . 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 substrate 12, the support member 14, and the mouthpiece 15. A plurality of sheet-like members may be used to form the packaging member 16 .

<Method of Using Cartridge 10 for Smoking Articles>
FIG. 4 shows an example of a method of using the smoking implement cartridge 10 . The smoking article cartridge 10 is used by being attached to an induction heating smoking article 20 . The smoking article 20 includes an insertion port 21, a coil 22 and a circuit board (not shown).

The insertion opening 21 is a hole for inserting the smoking article cartridge 10 into the smoking article 20 , and is provided to extend 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 the insertion opening 21 . The coil 22 is provided so as to surround the smoking article cartridge 10 inserted into the smoking article 20 in the circumferential direction. The circuit board contains a CPU that controls the supply of alternating current to the coil 22 .

When the smoker turns on the smoking device 20 after inserting the smoking device cartridge 10 into the insertion opening 21 , the circuit board supplies alternating current to the coil 22 . As a result, an induced current flows through the susceptor 13 provided within the aerosol-forming substrate 12, and heat is generated in the susceptor 13 due to Joule heat and hysteresis loss. That is, the susceptor 13 is heated by induction. The heat transferred from the induction-heated susceptor 13 heats the aerosol-forming substrate 12 around the susceptor 13 to generate an aerosol.

At this time, when the smoker holds the mouthpiece 15 in his/her mouth and inhales, air flows into the one end E1 of the aerosol-forming substrate 12 from the outside of the smoking implement cartridge 10 through the opening 11M of the lid member 11 . This inflow of air causes the aerosol generated by the aerosol-forming substrate 12 to flow into the mouth of the smoker via the flow path 14P of the support member 14 and the mouthpiece 15.

<Effects of Lid Member 11 and Smoking Article Cartridge 10>
In the smoking implement cartridge 10 of this embodiment, the lid member 11 made of a non-porous material covers the one end E1 of the aerosol-forming substrate 12 . As a result, the one end E1 of the aerosol-forming substrate 12 is not exposed to the outside, so damage to the aerosol-forming substrate 12 caused by, for example, physical or chemical contact with the one end E1 of the aerosol-forming substrate 12 is prevented. suppressed. Thus, the aerosol-forming substrate 12 can be protected.

Also, the lid member 11 has one or more openings 11M. As a result, the gas flows into the one end E1 of the aerosol-forming substrate 12 from the outside through the opening 11M, and the gas is discharged from the one end E1 of the aerosol-forming substrate 12 to the outside. In other words, a gas flow path in the smoking device cartridge 10 is ensured. Therefore, the smoking implement cartridge 10 and the lid member 11 can protect the aerosol-forming base material 12 and secure a gas flow path in the cartridge.

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

In the following description, in order to avoid duplication of description, detailed descriptions of the same configurations as those of the smoking implement cartridge described in the above embodiment will be omitted.

[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. As shown in FIG. The smoking implement cartridge 10</b>A has a film-like member 17 between one end E<b>1 of the aerosol-forming substrate 12 and the lid member 11 . In this respect, the smoking implement cartridge 10A differs from the smoking implement cartridge 10 (FIG. 1) of the above embodiment. Except for this point, the smoking implement cartridge 10A according to Modification 1 has the same configuration as the smoking implement cartridge 10 described in the above embodiment, and exhibits the same effects.

The membrane member 17 is provided so as to block 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 .

[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. As shown in FIG. In this smoking implement cartridge 10C, the packaging member 16 is provided with a hole 16H. In this respect, the smoking implement cartridge 10C differs from the smoking implement cartridge 10 (FIG. 1) of the above embodiment. Except for this point, the smoking implement cartridge 10C according to Modification 3 has the same configuration as the smoking implement cartridge 10 described in the above embodiment, and exhibits the same effects.

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

In the smoking implement cartridge 10C, the opening 11M of the lid member 11 and the hole 16H of the packaging member 16 function as gas flow paths in the cartridge. Specifically, the air that has flowed in from the opening 11M flows along the axial direction (Y direction) of the aerosol-forming substrate 12, passes through the outer peripheral surface of the aerosol-forming substrate 12 from the hole 16H, and enters the air inside. flows in. As a result, the aerosol near the central axis of the aerosol-forming substrate 12 heated by the susceptor 13 and the aerosol on the outer peripheral side of the aerosol-forming substrate 12 having a lower temperature are mixed. Therefore, the smoker can obtain a stronger flavor and taste by using the smoking implement cartridge 10</b>C compared to the smoking implement cartridge 10 .

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

For example, in the above-described embodiment and modification, the smoking article cartridge 10 used in the induction heating smoking article 20 (FIG. 4) was described as an example, but the smoking article cartridge of the present invention does not generate heat. It may be used for smoking articles that include a body. That is, the smoking article cartridge of the present invention may not have a susceptor (the susceptor 13 in FIG. 1, etc.).

Further, in the above-described embodiment and modification, an example in which the opening 11M of the lid member 11 is provided in the central portion of the lid member 11 (on the central axis of the aerosol-forming substrate 12) is shown (FIG. 2). The opening 11M may be provided at other positions.

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

Further, in the above-described embodiment and modified example, the opening 11M of the lid member 11 has a circular planar shape, but the planar shape of the opening 11M may be an ellipse, a square, or other shape.

Moreover, in the above-described embodiment and modified example, an example in which 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 is shown (for example, FIG. 1). , lid member 11 , aerosol-forming substrate 12 , support member 14 and mouthpiece 15 may be partially exposed from packaging member 16 .

FIG. 9 shows another example of covering with the packaging member 16. FIG. 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 manner.

Further, in the third modification described above, an example in which the lid member 11 is provided with the opening 11M and the packaging member 16 is provided with the hole 16H has been described. A hole portion 16H may be provided.

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

Further, in the embodiment and modification described above, an example in which the opening 11M penetrates the lid member 11 in the Y direction has been described, but the opening 11M does not have to penetrate the lid member 11 . For example, the opening 11M may be a recess provided on the surface of the lid member 11 on the aerosol-forming substrate 12 side. At this time, it is possible to suppress leakage of the constituent material of the aerosol-forming substrate 12 . For example, when the packaging member 16 is provided with holes 16H (for example, FIGS. 7 and 10), the constituent material of the aerosol-forming substrate 12 may leak outside from the holes 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 substrate 12 in the opening 11M before it leaks out from the hole 16H, and this leakage can be suppressed.

Alternatively, the recessed opening 11M may be provided on the side of the lid member 11 opposite to the aerosol-forming substrate 12, that is, on the side where the smoking article (for example, the smoking article 20 in FIG. 4) is inserted. At this time, the insertion of the smoking implement cartridge 10 into the smoking implement becomes easier. Specifically, when the smoker presses the vicinity of the recessed opening 11M, the lid member 11 is deformed. The implement cartridge 10 can be easily inserted into the smoking implement.
