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 method of heating the filler assembly, it is known to provide a susceptor made of a magnetic material inside the filler assembly and heat the filler by induction heating of the susceptor from a smoking tool. For example, Japanese Patent Application Laid-Open No. 2002-300003 discloses a smoking device cartridge in which a susceptor 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 cartridge 1 for smoking devices can be fitted to the insertion portion 51 provided in the smoking device 2 into which the cartridge 1 is inserted with an appropriate force. The attachment and detachment of the smoking implement cartridge 1 can be facilitated while allowing the smoking implement cartridge 1 to be suitably held by the smoking implement 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 formed, for example, 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 filling material 10 is formed into a substantially cylindrical shape by bundling a long filling material 20 along the length direction and winding it with a sheet-like wrapping member 25 . Filler 20 is formed from tobacco or non-tobacco plants. The packing mass 10 has a length of 10-25 mm. In addition, the filler 20 is not limited to a long shape, and may be in other forms such as granular, dusty, paste-like, and porous. Further, the smoking device cartridge 1 may have dimensions different from those described above in accordance with the shape of the smoking device 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 30 is provided inside the packing assembly 10 . The susceptor 30 has a metal plate 31 which is a flat plate member. The arrangement of the metal plate 31 on the susceptor 30 will be described later in detail.

The metal plate 31 is made of a metal material containing a magnetic substance. 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 metal plate 31 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 combination of these. 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.

Also, the metal plate 31 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.

Similarly, the susceptor 30 may be combined with a ferromagnetic, paramagnetic or diamagnetic metal plate 31 . For example, a metal plate 31 made of nickel, which is a ferromagnetic material, and a metal plate 31 made of iron, which is a ferromagnetic material, are physically adhered together, or the metal plate 31 and a paramagnetic material Physical contact with the metal plate 31 made of aluminum, which is the material of the metal plate 31 , and covering the outer surface of the metal plate 31 with the metal plate 31 .

(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 30 to 70 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-shaped 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 heat the susceptor 30 by inductively coupling with the metal plate 31 of the susceptor 30 included in the packed assembly 10 inserted into the insertion section 51 . When the susceptor 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 30 . As a specific example, the induction heating unit 52 heats the susceptor 30 by the magnetic force supplied to the metal plate 31, and periodically (for example, once every 1 ms) the DC power of the DC power supplied to the induction heating unit 52. By detecting the apparent ohmic resistance of the susceptor 30 determined from the voltage and the DC current drawn from the DC power supply, the resistance value of the susceptor 30 at the time of detection can be detected. That is, when the metal plate 31 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 whether the temperature of the susceptor 30 is below 308° C., above 308° C. and below 770° C., or above 770° C. based on the apparent ohmic resistance of the metal plate 31 .

(Composition of filling material)
The filling 20 is made by mixing dried and pulverized non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, an additive that adds flavor, a preservative, an adhesive or a thickener, and the like, and is formed into a sheet form. It is formed by molding into and then cutting to have a predetermined width and length. In addition, the filler 20 is not limited to a long shape, and may have various shapes. For example, it may be formed into a paste or granules.

When the filler 20 is configured in a long shape, the cross section orthogonal to the central axis is substantially rectangular, and the ratio of the long side to the short side of the cross section is, for example, in the range of 1:1 to 30:1. is preferred.

The manufacturing process of the filling 20 includes a drying/pulverizing step of drying/pulverizing a tobacco plant or a non-tobacco plant as a main raw material and weighing, etc., a preparatory step of pretreating other raw materials, weighing, etc., and a raw material. 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 step. 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.

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 is determined by, for example, 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.

Other means may be used in the filling molding step, such as molding the composition 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.

Referring to FIG. 6, there is shown an explanatory view for explaining a manufacturing method of a smoking implement cartridge 201 filled with a paste-like filler. Hereinafter, a smoking implement cartridge 201 filled with a paste-shaped filler (hereinafter referred to as a filler 220 to distinguish it from a sheet-shaped filler 20) A manufacturing method of a smoking implement cartridge 201 to be distinguished from the smoking implement cartridge 1 described above will be described.

The manufacturing method of the smoking article cartridge 201 includes a susceptor mounting step S21, a skeleton member mounting step S22, a filler filling step S23, a drying step (not shown), a filter mounting step (not shown), and a packaging step. Note that the filter attaching process and the packaging process are the same as the manufacturing method in the manufacturing method of the cartridge 101 for smoking implements, so descriptions thereof will be omitted here.

First, in the susceptor mounting step S21, the metal plate 31 is inserted into the jig 241. As shown in FIG. Here, the jig 241 is, for example, a cylindrical projection with a diameter of 4.0 mm to 7.5 mm and a length of 30 to 70 mm along the central axis, similar to the outer shape of the sealing member 18 of the smoking implement cartridge 1. 241a is the base formed. As a result, the jig 241 can support the frame member 116 by fitting the projection 241 a to the upstream end of the frame member 116 similar to the smoking device cartridge 101 . Further, the jig 241 is provided with a susceptor mounting hole 241b. Specifically, the susceptor mounting hole 241b is formed so that the metal plate 31, that is, the susceptor 30, is positioned at the same position as the susceptor 30 in the smoking device cartridge 1 when the skeleton member 116 is fitted to the projection 241a. It is a hole that can be supported.

Next, in the framework member attaching step S22, the framework member 116 is attached to the jig 241 and supported by fitting the projection 241a of the jig 241 to the upstream end of the framework member 116 . Next, in the filling material filling step S23, the filling nozzle filling material 243 is inserted from the downstream end of the skeleton member 116, and the filling material formed into a paste is filled.

Next, in the drying step, the filler 220 filled in the skeleton member 116 in the filler filling step S23 is dried by heating at 30 to 50.degree. As a result, the filling material molded into a paste form becomes a porous filling material 220 by volatilizing the internal moisture.

In the smoking device cartridge 201 manufactured by such a manufacturing method, the filler 220 molded into a paste-like shape is arranged on the upstream side of the smoking device cartridge 201, and the filler is separated by the length of the space C. 220 and metal plate 31 can be positioned downstream.

Instead of the frame member attaching step S22, the filler filling step S23, and the filler filling step S23, a porous filler formed in advance is fitted from one end of the skeleton member 116. The metal plate 31 is inserted while adjusting the position of the filler by pressing the downstream end of the skeleton member 116 against the protrusion 241 a of the jig 241 . good too. Such a process eliminates the need to use the jig 241 during the drying process, thereby reducing equipment costs.

Within the scope of the idea of the present invention, those skilled in the art can come up with various modifications and modifications, and it is understood that these modifications and modifications also belong to the scope of the present invention. For example, additions, deletions, or design changes of components, or additions, omissions, or conditional changes to the above-described embodiments by those skilled in the art are also subject to the gist of the present invention. is included in the scope of the present invention as long as it has

As described above, in the smoking device according to the first embodiment, the smoking device cartridge 1 used by being attached to the induction heating type smoking device 2 is a filler that generates an aerosol when heated. The smoking article cartridge 1 has a stack 10 and a susceptor 30 that is arranged inside the filling stack 10 and is induction-heated from the outside. 30 includes a flat metal plate 31 extending in the longitudinal direction. The flat metal plate 31 has a thickness of 0.1 to 1.0 mm and a width of 1 mm when viewed in a radial cross section of the smoking implement cartridge 1. .0 to 6.0 mm.

Therefore, since the susceptor 30 including the plurality of metal plates 31 extending in the longitudinal direction is used, the heat storage property of the metal plates 31 can be improved. In addition, by using the susceptor 30 containing a plurality of metal plates 31 , it is possible to cut a single susceptor containing the same amount of metal as the susceptor 30 , that is, a metal member larger than the metal plate 31 during manufacturing. The susceptor 30 can be cut with a relatively small force, and wear of, for example, a roller cutter used to cut the susceptor 30 can be reduced. Furthermore, compared to the case of using, for example, a cylindrical susceptor material, the metal plate 31 has a larger surface area than the cylindrical susceptor material, so the friction with the filler assembly 10 can be increased. The position of the metal plate 31 with respect to the filler assembly 10 can be preferably maintained, thereby preventing the metal plate 31 from falling off from the filler assembly 10 during smoking, and preventing the metal plate 31 from falling off from the filler assembly 10 during the cutting step S3. It is possible to suppress the displacement of the plate 31 .

The flat metal plate 31 has a thickness of 0.1 to 0.3 mm and a width of 1.0 to 4.0 mm when viewed in a radial cross section of the smoking device cartridge 1. , the balance of manufacturability and friction can be optimized.

<Second embodiment>
The second embodiment will be described below with reference to FIG.
The description of the configuration common to the first embodiment will be omitted, and only the portions different from the first embodiment will be described here.
Referring to FIG. 7, a cross-sectional view of section II in FIG. 1 according to the second embodiment is shown. A susceptor 330 according to the second embodiment has four metal plates 331 , 331 .

On the susceptor 330, four metal plates 331, which are thinner than the metal plates 31 in the first embodiment, are arranged at positions shifted by 90° in phase with the point P as the axis, that is, at equal intervals. is set.

Specifically, the metal plate 331 has a thickness of 0.1 to 1.0 mm and a width of 0.25 to 2 mm, preferably a thickness of 0.1 to 0.3 mm and a width of 0.25 to 2 mm. It is formed to be 5 to 1.5 mm. In addition, the metal plate 331 has a distance L1 from the radial center of the filler 20 (corresponding to the point P) to the cross-sectional center of the metal plate 31 (corresponding to the point Q), and a distance from the inclusion member 25 to the metal plate 31 is defined as the distance L2, the distance L1:the distance L2 is set to be 1:3 to 1:1, preferably 1:2 to 2:3.

By setting the number of the metal plates 331 of the susceptor 330 to four in this way, the susceptor 330 uses metal plates 331 that are narrower than the metal plates 31 of the susceptor 30 in the first embodiment. The heating temperature can be made equivalent to that of the susceptor 30 using one metal plate 31 . In addition, by using the metal plate 331 that is thinner than the metal plate 31, in the step of cutting the filler assembly 10C, such as the cutting step S3 of the method for manufacturing the filler assembly, the force required for cutting is reduced. can be further reduced.

Considering the cross-sectional area, that is, the thickness of the metal plate 331, when the metal plate 331 is cut by a roller cutter (not shown) in the cutting step S3, the thicker the metal plate 331, the higher the rigidity. can be done. On the other hand, the thinner the metal plate 331 is, the easier it is to cut. Therefore, it is possible to suppress the deformation of the filler 20 due to the pressing of the metal plate 331 by the roller cutter. In addition, the thicker the metal plate 331, the more heat generated by Joule heat.

Therefore, when the metal plate 331 is formed in a flat plate shape and has a thickness of 0.1 to 1.0 mm and a width of 0.25 to 2 mm, the packed body 10C is cut by a roller (not shown) in the cutting step S3. It is possible to achieve both of the above advantages when cutting with a cutter. Further, when the thickness is 0.1 to 0.3 mm and the width is 0.5 to 1.5 mm, the filler assembly 10C can maintain an appropriate amount of heat generated by Joule heat.

In each embodiment of the present invention, an example in which the smoking implement cartridge 1 is provided with the support member 12 is shown, but the present invention is not limited to this. The filling assembly 10 of the smoking device cartridge 1 is arranged inside the smoking device cartridge 1 so as to be restrained from moving toward the mouthpiece 14 even without the support member 12, like the smoking device cartridge 201, for example. The support member 12 need not be provided as long as it is fixed between the peripheral surface and the packing assembly 10 .

Further, in the present embodiment, the susceptor 30 is arranged in the center of the filler assembly 10 when viewed in the radial direction, but it may be arranged outside the radial center of the filler assembly 10 . Further, in the present embodiment, the cylindrical metal plate 31 is used for explanation, but it may be in a complicated shape such as a strip shape, or in a spirally wound shape.
