BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a smoking article cartridge used by being attached to an induction heating smoking article.

2. Description of the Related Art In recent years, there have been widely known tobacco products in which vaporized tobacco components are inhaled by heating a tobacco cartridge containing tobacco components without using a flame. In addition, due to the diversification of tastes, smoking implements using cartridge products for enjoying the aroma and taste of plants that do not contain tobacco components without using flames, like cigarettes, are beginning to become known.

In such a smoking tool, an aerosol is generated by heating a filling assembly in which the filling is accumulated. As a heating method of the filler assembly, it is known to provide a susceptor member made of a magnetic material inside the filler assembly, and to heat the filler by induction heating the susceptor member from the smoking tool. For example, Japanese Patent Application Laid-Open No. 2002-300003 discloses a smoking device cartridge in which a susceptor member is provided in a packing assembly.

Duplicate explanations are omitted. Also, the dimensional ratios in the drawings are exaggerated for convenience of explanation, and may differ from the actual ratios.

(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. , a mouthpiece 14 having a mouthpiece 14a at one end and a sealing member 18 having an inlet 18a at the other end are arranged along the longitudinal direction and are integrally formed by being wound with a sheet-like packaging member 16. It is 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 mouthpiece 14 . The support member 12 is provided, for example, in a cylindrical and solid shape, and is arranged between the filling assembly 10 and the mouthpiece 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 supporting member 12 is not always necessary, and if the accumulated filling body 10 is not easily moved toward the mouthpiece 14 (for example, the accumulated filling body 10 is fixed to the packaging member 16), The support member 12 may not be provided.

(Composition of mouthpiece)
The mouthpiece 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 more along the central axis. The mouthpiece 14 is formed using paper or the like, for example. Further, the mouthpiece 14 may be provided in a cylindrical shape by winding a sheet-like member made of paper, for example, or may include a cellulose acetate filter or the like for removing fine particles. The mouthpiece 14 is a white filter having a function of filtering some of the fine particles in the water vapor and aerosol generated in the packing assembly 10 . As will be described later, the filling 20 is made from a non-tobacco plant, so the mouthpiece 14 is not necessarily required.

(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, dusty, paste-like, and porous. 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 filling assembly 10 is equal to the outer diameters of the support member 12 and the mouthpiece 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 packing 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 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, bismuth, and chromium. mentioned. 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, the ferromagnetic material has a high Curie temperature, for example, about 358° C. for nickel. 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. Examples thereof include a combination of ferritic stainless steel and nickel, and more preferably an alloy combining iron, chromium, and aluminum (iron-chromium-aluminum alloy).

Here, the relationship between the temperature and magnetism of iron and chromium will be explained. Iron has a Curie temperature of about 770 ° C., which is the temperature at which a ferromagnet changes to a paramagnetic substance, and chromium changes from a ferromagnetic substance to a paramagnetic substance. is about 308°C.

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 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 arrangement of the susceptor member 30 will be described later.

The susceptor member 30 occupies 100% of the total length of the packed assembly 10 . That is, the susceptor member 30 has a length that spans the entire length of the packed assembly 10 . The susceptor member 30 does not have to extend over the entire length of the packed assembly 10 , and the length of the susceptor member 30 may be 25% or more and 100% or less of the total length of the packed assembly 10 . Thereby, the temperature of the filler 20 can be reliably raised by the susceptor member 30 .

(Structure of sealing member)
The sealing member 18 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. As with the mouthpiece 14, the sealing member 18 may be provided in a cylindrical shape by winding a sheet-like member made of paper, for example. The sealing member 18 has a function of allowing air to pass from the introduction portion 18a, that is, from the upstream side toward the packed assembly 10. As shown in FIG. Further, the sealing member 18 can absorb residual liquid remaining in the packing assembly 10 and liquefied among water vapor and aerosol generated in the packing assembly 10 . By making the sealing member 18 a different color (for example, black) from the color of the mouthpiece 14 , it is possible to easily determine the upstream side and the downstream side of the smoking implement cartridge 1 .

(Usage mode of smoking article cartridge)
FIG. 2 shows a cross-sectional view showing a usage pattern of the smoking implement cartridge 1. As shown in FIG. The smoking implement cartridge 1 is used with the sealing member 18 side attached to the smoking implement 2 . The smoking implement 2 has an insertion portion 51 into which the smoking implement cartridge 1 is inserted. The smoking article 2 is provided with an induction heating section 52 along the insertion section 51 . The induction heating section 52 includes an induction coil and can be inductively coupled with the susceptor member 30 included in the packed assembly 10 inserted into the insertion section 51 to heat the susceptor member 30 . When the susceptor member 30 is heated, the surrounding filling 20 is heated and an aerosol can be generated. In this state, the smoker can inhale the airflow containing the aerosol by inhaling from the mouthpiece 14 .

Furthermore, the smoking article 2 can detect the temperature of the susceptor member 30 . As a specific example, the induction heating unit 52 heats the susceptor member 30 by the magnetic force supplied to the susceptor member 30 , and periodically (for example, once every 1 ms) the DC of the DC power supplied to the induction heating unit 52 . By detecting the apparent ohmic resistance of the susceptor member 30 determined from the power supply voltage and the DC current drawn from the DC power supply, the resistance value of the susceptor member 30 at the time of detection can be detected. That is, when the susceptor member 30 is made of an iron-chromium-aluminum alloy, the magnetism of chromium changes from diamagnetism to paramagnetism at 308°C, and the magnetism of iron changes from ferromagnetism to paramagnetism at 770°C. can detect the temperature of the susceptor member 30 based on the apparent ohmic resistance of the susceptor member 30, whether it is less than 308°C, 308°C or more and less than 770°C, or 770°C or more.
