(Overall Configuration of Smoking Article Cartridge)
An embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a cross-sectional view of a smoking article cartridge 1 having a filler assembly 10 according to this embodiment. As shown in this figure, the smoking device cartridge 1 comprises a substantially cylindrical filler assembly 10 filled with a large number of fillers 20 and a support member 12 through which the airflow from the filler assembly 10 can pass. , and a filter member 14 having a suction port 14a at one end thereof are arranged along the longitudinal direction and wound with a sheet-like packaging member 16 to be integrally formed. The packaging member 16 can be made of paper or the like.

In this embodiment, the smoking implement cartridge 1 has a diameter of 4.0 mm to 7.5 mm, preferably 5.0 mm to 7.0 mm, and a length of 40 mm to 80 mm. If the outer diameter of the smoking device cartridge 1 is set in the range of 6.5 to 7.5 mm, the diameter becomes smaller than that of the insertion portion 51 provided in the smoking device 2 into which the smoking device cartridge 1 is inserted. It becomes easy to insert 1 into the smoking article 2. If the length of the smoking article cartridge 1 is set in the range of 40 to 80 mm, it will be longer than the length of the insertion portion 51 provided in the smoking article 2 for receiving the smoking article cartridge 1. The mouthpiece 14a can be exposed from the smoking implement 2 even if it is inserted into the smoking implement 2, and the length necessary for the smoker to smoke can be ensured.

(Structure of support member)
The support member 12 suppresses the movement of the aggregated filler 10 toward the support member 12 and allows the airflow containing the aerosol generated in the aggregated filler 10 to flow toward the filter member 14 . The support member 12 is provided, for example, in a cylindrical and solid shape, and is arranged between the filler aggregate 10 and the filter member 14 so that its axial direction is along the central axis. The support member 12 is, for example, formed to have an outer diameter of 4.0 mm to 7.5 mm and a length of 50 mm or less along the central axis. Note that the support member 12 may have dimensions different from those described above depending on the function and configuration as appropriate.

The support member 12 is made of a resin material. Examples of the resin material forming the support member 12 include polypropylene, polylactic acid, and silicone. However, the support member 12 may be made of a resin material other than this, or a material other than the resin material such as wood or metal (aluminum, etc.) that increases the cooling effect. Note that the support member 12 is not necessarily required, and the support member 12 may not be provided as long as the structure does not allow the packed product 10 to easily move toward the filter member 14 side.

(Configuration of filter member)
The filter member 14 is formed in a cylindrical shape, for example, with a diameter of 4.0 mm to 7.5 mm and a length of 50 mm or less along the central axis. The filter member 14 is formed using paper or the like, for example. The filter member 14 may be provided in a cylindrical shape by winding a sheet-shaped member made of paper, for example, or may include a cellulose acetate filter or the like for removing fine particles. The filter member 14 has a function of filtering some of the fine particles in the water vapor and aerosol generated in the packing assembly 10 .

(Structure of Packing Aggregate)
The packed product 10 is formed by bundling a long filler 20 along the length direction and winding it around a sheet-like packaging member 25 to form a substantially cylindrical shape. Filler 20 is formed from tobacco plants or non-tobacco plants. The filler 20 is not limited to a long shape, and may be in other forms such as granular or dusty. The packing mass 10 has a length of 10-25 mm. The smoking implement cartridge 1 may have dimensions different from those described above in accordance with the shape of the smoking implement 2 .

The outer diameter of the packed assembly 10 is equal to the outer diameter of the support member 12 and the filter member 14, and has a substantially constant value along the central axis. The size of this outer diameter is, for example, preferably in the range of 4.0 mm to 7.5 mm, more preferably in the range of 5.0 mm to 7.0 mm.

A susceptor member 30 is provided inside the filling assembly 10 . The susceptor member 30 can be induction heated by an external magnetic field. Therefore, the susceptor member 30 is made of a metallic material containing a magnetic material. Magnetic substances are roughly classified into ferromagnetic substances, paramagnetic substances, and diamagnetic substances. Among magnetic materials, ferromagnets are materials that strongly assume magnetism in the same direction as the external magnetic field when an external magnetic field is applied, and retain strong magnetism even when the external magnetic field is zero. Ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, and the like. The relative magnetic permeability of a ferromagnetic material is much greater than 1. For example, iron is about 5000, nickel is about 600, cobalt is about 250, and ferritic stainless steel is about 250. It is about 1000-1800.

Among magnetic substances, a paramagnetic substance is a material that becomes weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and loses its magnetism when the external magnetic field is reduced to zero. Examples include aluminum, platinum, and manganese. . The relative permeability of a paramagnetic material is slightly greater than 1. For example, aluminum is about 1.000021, platinum is about 1.000265, and manganese is about 1.000830. A diamagnetic material among magnetic materials 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. Examples include copper, graphite, and bismuth. be done. The relative magnetic permeability of a diamagnetic material is slightly less than 1. For example, copper is about 0.999990, graphite is about 0.99980, and bismuth is about 0.999834. .

In ferromagnetic materials, when an alternating magnetic field is generated, not only does an induced current flow and Joule heat is generated, but also heat (hysteresis loss) is generated due to friction and vibration between molecules. Induction heating can be performed more easily than in the conventional method, and the packed assembly 10 can be sufficiently heated.

In addition, ferromagnetic materials have a high Curie temperature, for example, nickel is about 358°C. Therefore, even when the smoking device cartridge 1 is heated at a high temperature of 200° C., for example, the heating temperature does not reach the Curie temperature, the properties of the ferromagnetic material can be maintained, and the filling assembly 10 can be heated stably. can.

The susceptor member 30 is made of a ferromagnetic material such as iron, ferrite iron, ferrite powder, ferrite particles, ferrite stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, or a metal material in which these are combined. may be adopted. For example, a combination of ferritic stainless steel and nickel may be used. Further, the susceptor member 30 may be made of a metal material containing a ferromagnetic material as a main component. good. Examples thereof include nickel alloys and nickel-iron alloys. Even in this case, the filling assembly 10 can be sufficiently heated by inductively heating the ferromagnetic material. A metal material including a paramagnetic substance and a diamagnetic substance may be used instead of the ferromagnetic substance. Even in this case, induction heating itself is possible. However, from the viewpoint of shortening the heating time and reducing power consumption, it is preferable to use a metal material containing a ferromagnetic material.

The susceptor member 30 may be made of a combination of ferromagnetic, paramagnetic, or diamagnetic materials. For example, a first susceptor member made of nickel, which is a ferromagnetic material, and a second susceptor member made of iron, which is a ferromagnetic material, are physically adhered together, or Physical contact between the susceptor member and a third susceptor member made of aluminum, which is a paramagnetic material, and coating of the outer surface of the first susceptor member with the third susceptor member may be mentioned. . The details of the configuration of the susceptor member 30 will be described later.

The filling 20 is, for example, an aerosol former that generates an aerosol, a microcrystalline cellulose, an additive that adds flavor, a preservative, a binder, or a thickener, etc., mixed appropriately with the dried and pulverized non-tobacco plant. , pulverized or classified into powder or granules, or formed into a paste. Also, the aerosol-forming base material 23 is formed into a sheet shape and then cut into strips or rods having a predetermined width and length.

For example, if the part of the non-tobacco plant is a leaf, preferably tea can be used. Not only are tea plants different in tea, but even the same plant can be made into different teas depending on the processing method.

For these teas, tea leaves after drinking may be used. Expensive tea can be reused and effectively utilized by using used tea leaves.

Furthermore, extracts of non-tobacco plants exemplified above, so-called extracts and processed products can also be used. The forms of the extract include liquid, starch syrup, powder, granules, solution and the like.

Aerosol formers as raw materials for the filler 20 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, and triethyl citrate. , isopropyl myristate, methyl stearate, dimethyl dodecanedioate, dimethyl tetradecanedioate, and the like. Among them, glycerin and propylene glycol are preferred.

Microcrystalline cellulose as a raw material of the filler 20 is, for example, obtained by partially depolymerizing α-cellulose obtained from fibrous plant pulp with an acid, and removing the soluble portion from the cellulose. , where appropriate, crystallized insoluble portions.

Microcrystalline cellulose can be used as a powder, or it can be dispersed in a solvent such as water and used as a suspension liquid. In this case, a high-speed stirrer, a high-pressure homogenizer, or the like can be used for dispersion in the solvent.

Furthermore, a flavor additive that adds flavor as a raw material for the filling 20 is preferably used as necessary. Examples of flavor additives include mint, cocoa, coffee, black tea extract, catechin powder of tea extract, and the like. As the preservative, those used in foods are preferred, and examples thereof include sorbic acid, potassium sorbate, benzoic acid, sodium benzoate and the like.

The filler 20 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. Mint, mint, peppermint oil, and others containing menthol may also be used.

The flavor additive is provided on the filter member 14 by impregnating the wall of the filter member 14, for example. The mode in which the flavor additive is provided in the filter member 14 is not limited to this mode. A flavor additive may be provided at 14 . Alternatively, a capsule containing a flavor additive may be placed between the filter member 14 and the filling assembly 20 . When the flavor additive is enclosed in a capsule, the smoker can break the capsule by pressing the capsule with a finger, and can volatilize the aromatic component of the flavor additive at a desired timing. Become.

Furthermore, if the flavor additive is encapsulated in microcapsules, for example, the encapsulated microcapsules may be provided in the filling assembly 10 . Of course, the microcapsules may be provided on the support member 12 as well.

(Manufacturing process of filling)
The manufacturing process of the filling 20 includes a drying/pulverizing step of drying/pulverizing a tobacco plant or non-tobacco plant as a main raw material and weighing, etc.; and a filling molding step of molding the composition.

In the drying and pulverizing step, the used parts of tobacco plants or non-tobacco plants (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.), which are the main raw materials, are processed into predetermined pulverized products in order to make compositions. . In this case, it is preferable to adjust the water content to be convenient for absorbing or supporting the aerosol former, water and other components to be added later. In drying, the temperature is preferably 60°C or higher and 80°C or lower. By setting it in this range, it is easy to reach the desired amount of water while avoiding the dissipation of the required flavor component. Furthermore, the drying/pulverizing step can be provided with a sieving step for sieving the pulverized material, and the pulverized material can be adjusted to a desired particle size and fed to the mixing step.

In the preparation process, raw materials necessary for producing the filling 20 can be prepared. The aforementioned microcrystalline cellulose is weighed in the preparation step and put into the mixing step.

A normal mixer can be used in the mixing process. For example, it is preferable to use a form in which the raw materials in the mixing tank are mixed with a stirring blade while applying a shearing force.

In the filling forming step, the composition in which various raw materials are mixed is formed into a thin sheet, and then cut to form the strip-shaped or rod-shaped filling 20 . In this embodiment, a plurality of roll mills are prepared in order to obtain a thin sheet. When multiple roll mills are used, it is possible to make a sheet of a desired thickness with a doctor blade while performing kneading and dispersion by compression by being pushed between narrow rolls and shearing by roll speed difference. ,preferable. Moreover, it can also be manufactured using a press roller or a press machine.

In addition, in order to obtain the powdery or granular filler 20, it is preferable to appropriately pulverize or classify the composition. The average particle size of the powdery or granular filler 20 is preferably, for example, 0.1 to 3.0 mm, more preferably 0.5 mm or less. The average particle size can be determined, for example, by the sieving method described in JIS K 0069:1992. In other words, this average particle diameter is the diameter corresponding to 50% of the mass obtained by accumulating the mass from the larger mesh size of the test results with a plurality of sieves. Alternatively, the average particle size may be the particle size at an integrated value of 50% in the particle size distribution determined by the laser diffraction/scattering method.

In the filling molding step, other means may be used, such as molding the composition by passing it through an orifice under pressure. In addition, in the filling molding step, if necessary, non-tobacco plants, aerosol formers, binders or thickeners, flavor additives, preservatives, etc. may be further added, and water etc. may be added. Also good.

The thickness of the sheet obtained in the filling molding process is preferably in the range of 0.1 mm to 1.0 mm, more preferably in the range of 0.1 mm to 0.5 mm. The obtained sheet is cut into a predetermined width by a cutter, a rotary cutter of rotary blade type, or the like.

Here, in the case of imparting adhesiveness to the surface of the filler 20, there is no particular limitation as long as it is a means capable of imparting adhesiveness. By imparting adhesiveness, when the strip-shaped or rod-shaped filler 20 and the powdery, granular or paste-shaped filler 20 are combined, the surface of the strip-shaped or rod-shaped filler 20 can be powdery, granular or pasty. The shaped filling 20 can be stably held.

(Structure of Susceptor Member)
FIG. 3 shows a perspective view of the susceptor member 30. As shown in FIG. The susceptor member 30 has a pin-shaped heating portion 31 inserted into the packing assembly 10 and a support portion 32 in which a portion of the outer peripheral surface of the heating portion 31 protrudes outward. The heating part 31 has a length equivalent to that of the packed mass 10, and has a sharp part 31a at the tip in the direction of insertion. The length of the susceptor member 30 is preferably equal to the length of the packing assembly 10, and has a length of 10-25 mm, and a diameter of, for example, a range of 0.5 mm-6.0 mm, more preferably It ranges from 1.0 mm to 3.0 mm.

The support portion 32 of the susceptor member 30 has an outer peripheral portion 33 that contacts the inner periphery of the packaging member 16 of the smoking device cartridge 1 . The support portion 32 is formed in a cylindrical shape to match the cylindrical shape of the smoking device cartridge 1 . The length of the support portion 32 is preferably in the range of 5% to 40% of the length of the packing assembly 10, more preferably in the range of 8% to 15%. The diameter of the support portion 32 is in the range of 70% to 100% of the inner diameter of the packaging member 25 around which the stuffing mass 10 is wrapped.

The heating portion 31 and the support portion 32 of the susceptor member 30 are integrally formed of the same material. However, the heating portion 31 and the support portion 32 may be formed separately from different materials and integrated later. Since the heating unit 31 heats the packed assembly 10, it is necessary to use at least a material that is induction-heated by an external magnetic field as described above. The support part 32 does not necessarily have to be made of a material that can be heated by induction. can be heated more efficiently.

Materials that can be used for the heating portion 31 and the support portion 32 include the aforementioned iron, ferritic iron, ferritic stainless steel, ferromagnetic steel, stainless steel, and ferromagnetic metals containing magnetic substances such as nickel and cobalt. body materials, paramagnetic materials such as aluminum, platinum or manganese, and diamagnetic materials such as copper or graphite. Furthermore, a metal material in which these are combined may be employed. For example, a combination of ferritic stainless steel and nickel may be used. Alternatively, it may be made of a metal material containing a ferromagnetic material as a main component. For example, a ferromagnetic alloy containing 60% or more, preferably 80% or more of a magnetic material may be employed. Examples of ferromagnetic alloys include nickel alloys and nickel-iron alloys.

A resin material can be used as a material other than a metal material containing a magnetic material that can be used for the support portion 32 . Examples of resin materials include polypropylene, polylactic acid (PLA), and silicone.

(Method of Forming Cartridge for Smoking Article)
The susceptor member 30 can be fixed by inserting the heating part 31 into the packing assembly 10 which is formed in a cylindrical shape in advance. Thereby, as shown in FIG. 1 , the support portion 32 of the susceptor member 30 is arranged at the tip portion of the side where the filling assembly 10 is inserted into the smoking article 2 . Since the heating portion 31 has a sharp portion 31 a at its tip, the heating portion 31 can be easily inserted into the packed material assembly 10 . The susceptor member 30 can be inserted until the support portion 32 comes into contact with the tip surface of the packed assembly 10 .

After inserting and fixing the susceptor member 30 into the pack of fillers 10, the pack of fillers 10, the support member 12 and the filter member 14 are arranged along the longitudinal direction, and wrapped with the wrapping member 16 to form the smoking device cartridge 1. can be formed. The packaging member 16 contacts the outer peripheral portion 33 of the support portion 32 of the susceptor member 30 . Therefore, the supporting portion 32 can prevent the susceptor member 30 from moving in the radial direction of the smoking device cartridge 1 or from changing its orientation. In addition, since the susceptor member 30 has the heating portion 31 and the support portion 32 , the heating portion 31 can be easily and reliably attached to the filler assembly 10 simply by inserting the susceptor member 31 into the filler assembly 10 . It can be placed at a given position and angle. In addition, since the support part 32 is arranged so as to cover the tip surface of the aggregated filler 10 , it is possible to prevent the filler 20 from dropping off from the aggregated filler 10 . In particular, when the filling material 20 is formed in a granular shape, the supporting part 32 functions as a lid, thereby effectively preventing the filling material 20 from coming off.

(First modification of susceptor member)
As shown in FIG. 4 , the susceptor member 60 of the first modified example has a heating portion 61 and a support portion 62 , and the support portion 62 has an outer peripheral portion 63 in contact with the packaging member 16 . The outer peripheral portion 63 has a heat insulating portion 64 on its surface. The heat insulating portion 64 is also formed on the surface of the support portion 62 that is exposed to the outside of the smoking device cartridge 1 . The heat insulating portion 64 is formed by covering the surface of the support portion 62 with a material having low thermal conductivity such as a resin material or a fiber material.
