Description

[Technical field]

[0001] The present invention relates to a cartridge for a smoking article having a filler made from tobacco or non-tobacco plant material, and to a smoking system including a cartridge for a smoking article. [Background technology]

[0002] In recent years, in order to comply with the trend towards smoking cessation, heated tobacco products that allow users to enjoy tobacco by heating a cartridge (smoking article cartridge) containing tobacco components without using a flame and inhaling the vaporized tobacco components have become popular. A smoking article cartridge has a tobacco filler that is heated by inserting a heating element such as a blade of the smoking article body, and a filter that is provided at the mouthpiece, and is formed by wrapping these in a packaging material such as paper. For example, Patent Document 1 lists such a smoking article cartridge.

[0003] Furthermore, Patent Document 2 discloses a system in which a cartridge for a smoking article is provided with a susceptor that heats by induction heating so as to heat tobacco filler in a non-contact manner by induction heating. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3212228 [Patent Document 2] Patent No. 6077145 Summary of the Invention [Problem to be solved by the invention]

[0005] On the other hand, in the case of Patent Document 1, when the blade-shaped heating body is inserted into the smoking article cartridge, a small amount of tobacco filler may fall off. This requires the smoking article body to be cleaned as needed, which may be cumbersome for the user. In the case of Patent Document 2, a plate-shaped susceptor is provided in the smoking article cartridge, and the tobacco filler is heated in a non-contact manner by dielectric heating, so that the heating body is not inserted and the tobacco filler is unlikely to fall off. However, since the tobacco filler contains an aggregate of crimped sheets, it is necessary to provide a thin susceptor suitable for heating this tobacco filler, and further to provide a device for generating a high frequency of 1 to 30 MHz suitable for heating the thin susceptor, and there may be concerns about the health effects of the user due to the use of high-frequency electromagnetic waves.

[0006] Furthermore, in the case of Patent Document 2, depending on the shape of the susceptor, the filler may not be heated stably.

[0007] Therefore, the present invention has been made in consideration of the above-mentioned problems, and one of its objects is to provide a smoking system that can heat tobacco filler without the filler falling off and while minimizing the effects of electromagnetic waves on the human body.

[0008] Another object of the present invention is to provide a cartridge for a smoking article and a smoking system that can stably heat the filler without causing the filler to fall out. [Means for solving the problem]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0029] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the present invention can be implemented in many different forms, and should not be interpreted as being limited to the description of the embodiments exemplified below. The drawings may be schematic in order to make the explanation clearer, but they are merely examples and do not limit the interpretation of the present invention.

[0030] Furthermore, the letters "first" and "second" attached to each element are convenient labels used to distinguish each element, and have no further meaning unless otherwise specified. In the drawings referred to in this embodiment, the same parts or parts having similar functions are given the same or similar symbols (symbols consisting of the number xxx with A, B or 1, 2, etc. attached thereto), and repeated explanations may be omitted. Also, some of the configuration may be omitted from the drawings. In addition, if a person having ordinary knowledge in the field to which the present invention belongs can recognize the above, no special explanation will be given.

[0031] First Embodiment A cartridge for a smoking article according to a first embodiment of the present invention will be described in detail with reference to the drawings.

[0032] (1-1. Configuration of a cartridge for smoking articles) Fig. 1 is a cross-sectional view of a cartridge 1 for a smoking article having a filler accumulation 10 in this embodiment, cut along a plane including a central axis C along the longitudinal direction. As shown in Fig. 1, the cartridge 1 for a smoking article includes the filler accumulation 10, a support member 20, a filter 30 serving as a mouthpiece, and a sheet-like outer packaging member 40 (also referred to as a packaging member). In the cartridge 1 for a smoking article, the filler accumulation 10, the support member 20, and the filter 30 are arranged along the longitudinal direction D1, and are integrally formed by wrapping the outer periphery of the filler accumulation 10, the support member 20, and the filter 30 with the outer packaging member 40. If the outer packaging member 40 has a certain strength, the support member 20 may not be provided.

[0033] The cartridge 1 for the smoking tool is formed to have an outer diameter of 4.0 mm to 7.5 mm, more preferably 5.0 mm to 7.0 mm, and a length of 40 mm to 80 mm. If the outer diameter of the cartridge 1 for the smoking tool is set in the range of 6.5 to 7.5 mm, it will be smaller than the diameter of the insertion part 50 for inserting the cartridge for the smoking tool provided in the smoking tool body 5 shown in Fig. 4, making it easy to insert the cartridge 1 for the smoking tool into the smoking tool body 5. If the length of the cartridge 1 for the smoking tool is set in the range of 40 to 80 mm, it will be longer than the length of the insertion part 50 for receiving the cartridge 1 for the smoking tool provided in the smoking tool body 5, so that even when the cartridge 1 for the smoking tool is inserted into the smoking tool body 5, the mouthpiece can be exposed from the smoking tool body 5, and the length necessary for a smoker to smoke can be ensured.

[0034] (1-2. Configuration of packing aggregate 10) Next, the configuration of the packing assembly 10 will be described. Fig. 2 is an end view of the packing assembly 10 as viewed from the outside. Fig. 3 is a cross-sectional view of the packing assembly 10 cut along a plane including a central axis C along the longitudinal direction of the packing assembly 10. As shown in Figs. 2 and 3, the packing assembly 10 includes a packing 11, a susceptor member 13, and an inner packaging member 15.

[0035] In the filler accumulation body 10, the filler 11 having a long (strip) shape is bundled along the longitudinal direction D1 and wrapped in a sheet-like inner wrapping member 15 to form a substantially cylindrical shape. The filler 11 is formed from a tobacco plant or a non-tobacco plant. The filler accumulation body 10 has a length of 10 to 25 mm. The cartridge 1 for a smoking article may have dimensions different from those described above, depending on the shape of the smoking article body 5.

[0036] The outer diameter D10 of the packing assembly 10 is equal to the outer diameters of the support member 20 and the filter 30, and is a roughly constant value along the central axis C. The size of this outer diameter D10 is preferably in the range of 4.0 mm to 7.5 mm, for example, and more preferably in the range of 5.0 mm to 7.0 mm.

[0037] The filler 11 is formed by mixing dried and ground non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, additives that add flavor, preservatives, adhesives or thickeners, etc., forming the mixture into a sheet, and then cutting it to a specified width and length.

[0038] When the filler 11 is configured in a long (strip) shape, the cross section perpendicular to the central axis is substantially rectangular, and the ratio of the long side to the short side of the cross section is preferably, for example, in the range of 1:1 to 30:1. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, more preferably in the range of 0.1 mm to 3.0 mm. The length of the short side 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. In addition, it is preferable that the length of the filler 11 is substantially the same as the length of the packing assembly 10. The length L11 of the filler 11 is preferably in the range of 10 mm to 25 mm, more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such a filler 11 is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm.

[0039] Next, a description will be given of specific examples of the raw materials used as the filler 11. The filler 11 is made of any one or a combination of the following raw materials.

[0040] The filler 11 is made from tobacco plants or non-tobacco plants. Examples of tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, homogenized tobacco, etc. Examples of non-tobacco plants include plants other than tobacco plants. Preferred parts of non-tobacco plants include leaves, pulp, seeds, roots (scale roots, tuberous roots, etc.), stems, tubers, skin (stem skin, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, branches, etc.

[0041] In this specification, "plants" refers to a group of animals, and includes not only living organisms that have roots and live in a fixed location, such as grass and trees, but also algae such as microalgae and seaweed, and fungi such as mushrooms.

[0042] For example, when the part of the non-tobacco plant is a leaf, tea can be preferably used. Not only do different plants produce different teas, but 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 pentaphyllum tea, aloe tea, ginkgo leaf tea, oolong tea, turmeric tea, Quercus salicina tea, Eleuthero tea, Plantain tea, Kakiodoshi tea, Persimmon leaf tea, Chamomile tea, Chamomile tea, Kawara Kesmei tea, Quince tea, Chrysanthemum tea, Gymnema tea, Guava tea, Wolfberry tea, Soft leaf tea, Black bean tea, Gennoshoko tea, Brown rice tea, Burdock tea, Comfrey tea, Bifu tea, Sakura tea, Examples include saffron tea, shiitake mushroom tea, perilla tea, jasmine tea, ginger tea, horsetail tea, Japanese laurel tea, swertia tea, buckwheat tea, taranoki tea, dandelion tea, sweet tea, Houttuynia tea, Eucommia tea, sword bean tea, elderberry tea, ratwort tea, Job's tears 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 melon tea. For these teas, tea leaves after drinking may be used. Using tea leaves allows expensive tea to be reused and put to good use.

[0043] Furthermore, extracts of non-tobacco plants such as those exemplified above, so-called extracts and processed products, can also be used. The extract may be in the form of liquid, starch syrup, powder, granules, solution, etc. Examples of aerosol formers as raw materials for the filler 11 include glycerin, propylene glycol, sorbitol, triethylene glycol, lactic acid, diacetin (glycerin diacetate), triacetin (glycerin triacetate), triethylene glycol diacetate, triethyl citrate, isopropyl myristate, methyl stearate, dimethyl dodecanedione, and dimethyl tetradecanedione. Among these, glycerin and propylene glycol are preferred.

[0044] The microcrystalline cellulose used as the raw material for the filler 11 is obtained, for example, by partially depolymerizing α-cellulose obtained from the pulp of a fibrous plant with an acid, and is obtained by removing the soluble portion from the cellulose and appropriately crystallizing the insoluble portion.

[0045] The microcrystalline cellulose may be in the form of a powder or may be dispersed in a solvent such as water to form a suspension. In this case, dispersion in the solvent can be performed using a high-speed stirrer or a high-pressure homogenizer.

[0046] Furthermore, if necessary, a flavor additive that adds flavor is preferably used as a raw material for the filling 11. Examples of the flavor additive include mint, cocoa, coffee, black tea extract, and tea extract catechin powder. Preservatives that are used in food are preferred, and examples of the preservative include sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

[0047] The filler 11 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 that obtained from natural products, and may be a synthetic product. In addition, peppermint, mint, peppermint oil, and other menthol-containing substances may be used.

[0048] The flavor additive is provided in the filter, for example, by impregnating the filter wall. The manner in which the flavor additive is provided in the filter is not limited to this manner, and the flavor additive may be provided in the filter, for example, by embedding a capsule in which the flavor additive is encapsulated in the filter wall. Alternatively, a capsule in which the flavor additive is encapsulated may be disposed between the filter and the accumulation of the filling 11. When the flavor additive is encapsulated in a capsule, the smoker can break the capsule by pressing it with his or her finger, and the aromatic component of the flavor additive can be volatilized at a desired timing.

[0049] Furthermore, when the flavor additive is, for example, encapsulated in a microcapsule, the encapsulated microcapsule may be provided in the accumulation of the filling 11. Of course, the microcapsule may be provided in the support member 12.

[0050] Binders or thickeners as ingredients of the filling 11 include gums such as guar gum, xanthan gum, gum arabic and locust bean gum; cellulose binders such as hydroxypropyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose and ethyl cellulose; polysaccharides such as starch, organic acids such as alginic acid, sodium alginate, sodium carboxymethyl cellulose, caranagin, conjugate base salts of organic acids such as agar and pectin, and combinations thereof.

[0051] (1-3. Configuration of susceptor member 13) The susceptor member 13 is provided inside the packing assembly 10. In this embodiment, one susceptor member 13 having a cylindrical shape is provided at the center of the packing assembly 10. The susceptor member 13 can be induction heated by a magnetic field generated from the outside (coil). For this reason, the susceptor member 13 is formed of a metal material including a magnetic body. Magnetic bodies are broadly classified into ferromagnetic bodies, paramagnetic bodies, and diamagnetic bodies. Among magnetic bodies, ferromagnetic bodies are materials that are strongly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and remain strongly magnetic even when the external magnetic field is zero. Examples of ferromagnetic bodies include iron, ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, and cobalt, which are ferromagnetic materials. The relative permeability of a ferromagnetic body is significantly larger than 1, for example, about 5000 for iron, about 600 for nickel, about 250 for cobalt, and about 1000 to 1800 for ferritic stainless steel.

[0052] Among magnetic bodies, paramagnetic bodies are materials that become weakly magnetized in the same direction as the external magnetic field when an external magnetic field is applied, and become non-magnetic when the external magnetic field is zero. Examples of paramagnetic bodies include aluminum, platinum, and manganese. The relative permeability of paramagnetic bodies is slightly larger than 1, for example, about 1.000021 for aluminum, about 1.000265 for platinum, and about 1.000830 for manganese. Among magnetic bodies, diamagnetic bodies are materials that become weakly magnetized in the opposite direction to the external magnetic field when an external magnetic field is applied, and become non-magnetic when the external magnetic field is zero. Examples of diamagnetic bodies include copper, graphite, chromium, and bismuth. The relative permeability of diamagnetic bodies is slightly smaller than 1, for example, about 0.999990 for copper, about 0.99980 for graphite, and about 0.999834 for bismuth.

[0053] When an alternating magnetic field is generated in a ferromagnetic material, not only does an induced current flow and generate Joule heat, but heat (hysteresis loss) is also generated due to friction and vibration between molecules. Therefore, ferromagnetic materials can be easily inductively heated compared to paramagnetic or diamagnetic materials, and the filler aggregate 10 can be sufficiently heated.

[0054] Furthermore, ferromagnetic materials have a high Curie temperature, for example, nickel has a Curie temperature of about 358° C. Therefore, even when the cartridge 1 for a smoking article is heated to a high temperature of, for example, 200° C., the heating temperature does not reach the Curie temperature, and the properties of the ferromagnetic material can be maintained, allowing the packing assembly 10 to be stably heated.

[0055] The susceptor member 13 may be made of a metal material such as iron, ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel (SUS430), nickel, cobalt, or a combination of these ferromagnetic materials. For example, a combination of ferritic stainless steel and nickel may be used. The susceptor member 13 may be made of a metal material containing a ferromagnetic material as a main component, and may be made of a ferromagnetic alloy that contains 60% or more, preferably 80% or more, of a magnetic material. For example, a nickel alloy or a nickel-iron alloy may be used, and more preferably, an alloy of iron, chromium, and aluminum. Even in this case, the ferromagnetic material is induction-heated, so that the packing assembly 10 can be sufficiently heated. Note that instead of the ferromagnetic material, a metal material containing a paramagnetic material and a diamagnetic material may be used. In this case, induction heating itself is possible. However, it is preferable to use a metal material containing a ferromagnetic material from the viewpoint of shortening the heating time and reducing power consumption.

[0056] The susceptor member 13 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 bonded together, or a first susceptor member and a third susceptor member made of aluminum, which is a paramagnetic material, are physically bonded together, or the outer surface of the first susceptor member is covered with the third susceptor member.

[0057] The susceptor member 13 may be made of a magnetic material or a material other than a magnetic material, the surface of which is plated with a magnetic material. For example, the susceptor member 13 may be made of iron, the surface of which is plated with zinc or nickel.

[0058] In the above, as shown in FIG. 3, it is desirable that the length L13 in the longitudinal direction of the susceptor member 13 is equal to or greater than the length L11 in the longitudinal direction of the filler 11.

[0059] The length L13 of the susceptor member 13 accounts for 100% of the total length of the packing assembly 10. In this example, the susceptor member 13 has a length that spans the entire length of the packing assembly 10. Note that the susceptor member 13 does not have to span the entire length of the packing assembly 10, and may have a length that spans 25% to 100% of the total length of the packing assembly 10. Since the longitudinal length L13 of the susceptor member 13 is equal to or greater than the longitudinal length L11 of the packing 11, it is ensured that the outer surface of the packing 11 comes into contact with any position on the outer surface of the susceptor member 13, thereby ensuring a rise in the temperature of the packing.

[0060] In this embodiment, the length of the susceptor member 13 is preferably greater than 9 mm. In this example, the length of the susceptor member 13 is 12 mm. The diameter of the susceptor member 13 is preferably 0.5 mm or greater. In this embodiment, the diameter of the susceptor member 13 is 1 mm. The volume of the susceptor member 13 is 2.5 mm. 3 In this embodiment, the volume of the susceptor member 13 is preferably 9.4 mm 3 It is.

[0061] (1-4. Configuration of Support Member) The support member 20 suppresses the movement of the packing accumulation 10 toward the support member 20, and allows the airflow containing the aerosol generated in the packing accumulation 10 to flow toward the filter 30. The support member 20 is provided, for example, in a cylindrical and solid shape, and is disposed between the packing 11 and the filter 30 so that its axial direction is along the central axis C. The support member 20 is formed, for example, with a length along the central axis C of 3.0 mm or more and 50 mm or less. The support member 20 may have dimensions different from those described above depending on the appropriate function and configuration.

[0062] (1-5. Filter configuration) The filter 30 is formed in a cylindrical shape, for example, with a diameter of 6.5 mm to 7.5 mm and a length along the central axis C of 50 mm or less. The filter 30 is a part that constitutes the mouthpiece of the cartridge 1 for a smoking device. The filter 30 is formed, for example, from paper or the like. The filter 30 may be provided in a cylindrical shape by rolling up a sheet-like member made of paper, or may include a cellulose acetate filter or the like that removes fine particles. The filter 30 has a function of filtering out some of the fine particles in the water vapor and aerosol generated in the packing accumulation 10.

[0063] (1-6. Smoking system configuration) FIG. 4 is a cross-sectional view of the smoking system 100 showing a usage form of the smoking article cartridge 1. FIG. 5 is a block diagram of the smoking article main body 5. The smoking article cartridge 1 is used by being attached to the smoking article main body 5. As shown in FIG. 4, the smoking article main body 5 includes an insertion section 50, a control device 51, a DC / AC inverter 52, a power supply section 53, and a coil 55. The smoking article cartridge 1 is inserted into the insertion section 50. The control device 51, the DC / AC inverter 52, the power supply section 53, and the coil 55 are provided inside the smoking article main body 5. The coil 55 is provided at a position of the smoking article cartridge 1 inserted into the insertion section 50 corresponding to the filler accumulation body 10. Specifically, the coil 55 is provided at a distal section 50b opposite to the entrance (proximal section) 50a of the insertion section 50.

[0064] As shown in Fig. 5, in the smoking accessory main body 5, the control device 51 includes a CPU (Central Processing Unit) 511, a memory 513 consisting of a RAM (Random Access Memory) and a ROM (Read On Memory), and an input / output interface 515. The control device 51 performs calculations in the CPU 511 using a program stored in the memory 513. The input / output interface 515 is connected to the DC / AC inverter 52 and the coil 55, and information is input and output. The power supply unit 53 supplies a DC current to the control device 51. The DC / AC inverter 52 supplies a high-frequency AC current. That is, in the smoking accessory main body 5, the direct current supplied from the power supply unit 53 is converted into an alternating current having a predetermined frequency by the DC / AC inverter 52 based on a command from the control device 51. The alternating current is supplied to the coil 55.

[0065] Based on the above, when the smoking device main body 5 is operated, an alternating current is applied to the coil 55. The frequency of the alternating current at this time is preferably controlled to be less than 1 MHz, preferably 1 kHz to 800 kHz, more preferably 50 kHz to 500 kHz, taking into consideration the effects of electromagnetic waves on the human body. In this way, an electromagnetic field is generated by the coil 55 in the distal portion 50b of the insertion portion 50 of the smoking device main body 5 while suppressing the effects on the human body. When the filler accumulation 10 is properly positioned in the insertion portion 50, the susceptor member 13 of the filler accumulation 10 is located in this electromagnetic field. The electromagnetic field generates eddy currents in the susceptor member 13, which results in the susceptor member 13 being resistively heated with respect to the eddy currents. The heated susceptor member 13 heats the filler 11 of the filler accumulation 10 to a temperature sufficient to form an aerosol. The aerosol is drawn downstream through the filler accumulation 10 and inhaled by the user.

[0066] By using the smoking system of this embodiment, the filler is stably heated by the susceptor member 13 that generates heat through induction heating while suppressing the effects of electromagnetic waves on the human body. This allows a stable aroma to be enjoyed. In addition, at this time, the blade-shaped heating element is not inserted into the filler accumulation body 10 in the smoking device main body 5. This also prevents the filler from falling off.

[0067] <Second embodiment> In the first embodiment of the present invention, an example in which one cylindrical susceptor member 13 is provided at the center of the packing assembly 10 has been described, but the present invention is not limited to this. In this embodiment, an example in which a plurality of susceptor members are provided will be described. Note that in this embodiment, explanations of configurations similar to those in the first embodiment will be omitted as appropriate. Also, for the sake of explanation, the packings in the drawings will be simply described.

[0068] FIG. 6 is an end view of the packing assembly 10A as viewed from the outside. As shown in FIG. 6, the packing assembly 10A includes two susceptor members 13A (susceptor members 13A-1 and 13A-2) in addition to the packing 11 and the packaging member 15. The susceptor members 13A-1 and 13A-2 are spaced apart at a predetermined interval. The susceptor members 13A-1 and 13A-2 may be spaced apart at a predetermined interval from the central axis C, or may be spaced apart at a predetermined angle from the central axis C. In this embodiment, the susceptor members 13A-1 and 13A-2 are spaced apart at a predetermined interval from the central axis C, and the centers of the susceptor members are arranged at positions that equally divide the length from the central axis C to the outer periphery of the packing assembly 10A. When there is no need to separately describe the susceptor members 13A-1 and 13A-2, they will be described as the susceptor member 13A.

[0069] The susceptor member 13A-1 and the susceptor member 13A-2 may be formed of the same magnetic material or different magnetic materials. By forming the susceptor member 13A-1 and the susceptor member 13A-2 of different magnetic materials, the susceptor member can be manufactured inexpensively. For example, by mixing a paramagnetic material with a ferromagnetic material, the manufacturing cost of the entire susceptor can be reduced. In addition, by using a ferromagnetic material for temperature control to detect the change in the Curie point, or by using a material other than a ferromagnetic material with good thermal efficiency for heat generation, different functions can be provided. In addition, in this embodiment, the susceptor member 13A has a cylindrical shape. In this case, the length of the susceptor member 13A may be the same as that of the susceptor member 13 of the first embodiment. On the other hand, the diameter of the susceptor member 13A may be smaller than that of the susceptor member 13 of the first embodiment. For example, the diameter of the susceptor member 13A may be 0.5 mm or more. In this embodiment, the diameter of the susceptor member 13A is 0.55 mm. The volume of the susceptor member 13A is 2.5 mm. 3 In this embodiment, the volume of the susceptor member 13A is preferably 2.85 mm 3 It is.

[0070] In this embodiment, the total surface area of ​​the susceptor members 13A is increased by having two susceptor members 13A. Therefore, even if the diameter of each susceptor member 13A is reduced, the susceptor members 13A can have a heating function for the filler 11 equal to or greater than that of the susceptor members 13.

[0071] Although the susceptor member 13A has a cylindrical shape, the present invention is not limited thereto. For example, FIG. 7 is an end view of the packing assembly 10B as viewed from the outside and an enlarged view of the susceptor member. As shown in FIG. 7, the packing assembly 10B has a susceptor member 13B (susceptor member 13B-1, susceptor member 13B-2). The susceptor member 13B may have an uneven portion 14 on the outer circumferential surface. This can increase the surface area of ​​the susceptor member 13B, and the area of ​​contact with the packing 11 is increased. Therefore, the heating function of the packing 11 can be further improved. The shape, number, dimensions, and arrangement of the uneven portion 14 are not limited to the example of FIG. 7, and can be set arbitrarily. For example, the uneven portion 14 can be in a range in which the distance from the surface of the susceptor member 13A to the highest protruding peak is 1.0 mm or less, and the distance from the surface of the susceptor member 13A to the deepest portion located at the deepest position toward the center is 1.0 mm or less. The uneven portion 14 can also be provided in the susceptor 13 of the first embodiment.

[0072] Fig. 8 is an end view of the packing assembly 10C as viewed from the outside. As shown in Fig. 8, the packing assembly 10C has six susceptor members 13C (susceptor members 13C-1 to 13C-6). The susceptor members 13C are spaced apart at a predetermined interval such that the angle θ between the center C and the centers of two adjacent susceptor members 13C is 60°. The susceptor members 13C have six susceptor members 13, which further increases the surface area. This can further enhance the heating function of the packing 11.

[0073] <Third embodiment> In the first and second embodiments of the present invention, an example has been shown in which the susceptor member 13 having a cylindrical shape is provided in the packing assembly 10, but the present invention is not limited to this. In the present embodiment, a susceptor member 13 having a different shape will be described.

[0074] FIG. 9 is an end view of the packing assembly 10D as viewed from the outside. As shown in FIG. 9, the packing assembly 10D has a susceptor member 13D. The susceptor member 13D has a cylindrical (hollow) shape. In the case of a cylindrical shape, the packing is disposed on the outside and inside of the susceptor member 13, so that the contact area with the packing is increased. In addition, by having a cylindrical shape, the distance D from the coil 55, which is a heating member, to the susceptor 13D becomes uniform. Therefore, by having a cylindrical shape, the heating function of the packing can be improved. The length of the susceptor member 13D is preferably greater than 9 mm. The outer diameter of the cylinder of the susceptor member 13D can be set arbitrarily within a range of 1 mm or more and less than 7.5 mm, preferably within a range of 3 mm or more and 7 mm or less. The difference (thickness) between the outer diameter and the inner diameter of the susceptor member 13Ea is preferably 0.1 mm or more.

[0075] FIG. 10 is an end view of the packing assembly 10E as viewed from the outside. As shown in FIG. 10, the packing assembly 10E has a susceptor member 13Ea and a susceptor member 13Eb. The susceptor member 13Ea and the susceptor member 13Eb may have different shapes. In this example, the susceptor member 13Ea has a cylindrical shape similar to the susceptor member 13D. The susceptor member 13Eb has a cylindrical shape (solid shape) similar to the susceptor member 13. The susceptor member 13Eb is provided at the center of the susceptor member 13Ea. When it is difficult to heat the packing 11 inside the susceptor member 13Ea, the susceptor member 13Eb can stably heat the packing 11. Therefore, the susceptor member 13E can enhance the heating function of the packing 11. The location where the susceptor member 13Eb is disposed is not particularly limited, and the susceptor member 13Eb may be disposed outside the susceptor member 13Ea. In this example, the length of the susceptor member 13Eb is preferably greater than 9 mm. The diameter of the susceptor member 13Eb is preferably 0.5 mm or more. The volume of the susceptor member 13Eb is preferably 2.5 mm. 3It is preferable that the length of the susceptor member 13Ea in this example is greater than 9 mm. The inner and outer diameters of the cylindrical susceptor member 13Ea are greater than the diameter of the susceptor member 13Eb, and can be set arbitrarily within a range of 1 mm or more and less than 7.5 mm, preferably 3 mm or more and 7 mm or less, of the packing assembly 10E. It is preferable that the difference (thickness) between the outer and inner diameters of the susceptor member 13Ea is 0.1 mm or more. The susceptor member 13Ea and the susceptor member 13Eb may be formed of the same magnetic material or different magnetic materials.

[0076] FIG. 11 is an end view of the packing assembly 10F as viewed from the outside. As shown in FIG. 11, the packing assembly 10F has a susceptor member 13F. The susceptor member 13F has a spiral shape. In the case of a spiral shape, the packing 11 is arranged on the outside and inside of the susceptor member 13, so that the contact area with the packing 11 is increased. Therefore, the heating function of the packing 11 can be improved. In addition, the susceptor member 13F can be appropriately deformed according to the shape of the packing 11. In addition, the susceptor member 13F can be formed, for example, by rolling a sheet-shaped magnetic material. Therefore, the susceptor member 13F can be easily manufactured. Since the susceptor member 13F is a sheet-shaped body, the packing assembly 10F can also be made lighter. The shape, number, dimensions, and arrangement of the susceptor member 13F are not limited to the example of FIG. 11 and can be set arbitrarily. The length of the susceptor member 13F is preferably 1.5 mm or more, and the thickness is preferably 0.1 mm or more.

[0077] FIG. 12 is an end view of the packing assembly 10G as viewed from the outside. As shown in FIG. 12, the packing assembly 10G has one susceptor member 13G. The susceptor member 13G may have a plate shape. In this case, the thickness of the susceptor member 13G is preferably 0.1 mm or more. In this example, the thickness of the susceptor member 13G is 0.2 mm. The width of the susceptor member 13G is preferably 1.5 mm or more. In this example, the width of the susceptor member 13G is 4 mm. The volume of the susceptor member 13G is 2.5 mm. 3 In this embodiment, the volume of the susceptor member 13G is preferably 9.6 mm 3 It becomes.

[0078] Although one plate-shaped susceptor member is provided in FIG. 12, multiple susceptor members may be provided. FIG. 13 is an end view of the packing assembly 10H as viewed from the outside. As shown in FIG. 13, the packing assembly 10H may have multiple plate-shaped susceptor members 13H (susceptor members 13H-1, 13H-2). The susceptor members 13H-1 and 13H-2 are spaced apart at a predetermined interval. The susceptor members 13H-1 and 13H-2 may be spaced apart at a predetermined interval with respect to the central axis C, or may be spaced apart at a predetermined angle with respect to the central axis C. The susceptor members 13H-1 and 13H-2 in this embodiment are spaced apart from each other at a predetermined interval with respect to the central axis C, and the centers of the susceptor members are arranged at positions that equally divide the length from the central axis C to the outer periphery of the packing. In this example, the susceptor members 13H-1 and 13H-2 have the same shape, but may have different shapes depending on the number of susceptor members, and may be made of the same magnetic material or different magnetic materials. The thickness of the susceptor member 13H is the same as that of the susceptor member 13G. On the other hand, the width of the susceptor member 13H may be smaller than that of the susceptor member 13G. In this case, the width of the susceptor member 13H is preferably 1.5 mm or more. In this example, the width of the susceptor member 13H is 1.5 mm. In this case, the volume of the susceptor member 13H is 7.2 mm3 , and the volume is smaller than that of the case of one susceptor member 13G. In this embodiment, by having two susceptor members 13H, the total volume of the susceptor members 13H may be smaller. The total surface area is larger. Therefore, even if the width of each susceptor member 13H is reduced, it is possible to maintain a heating function for the filler 11 equal to or greater than that of the susceptor member 13G.

[0079] The susceptor member 13H may have an uneven portion on its outer circumferential surface. This increases the surface area of ​​the susceptor member 13H and the area of ​​contact with the filler 11. This increases the heating function of the filler 11. The shape, number, dimensions, and arrangement of the uneven portion can be set arbitrarily. For example, the uneven portion can be in a range in which the distance from the surface of the susceptor member 13H to the highest protruding peak is 1.0 mm or less, and the distance from the surface of the susceptor member 13H to the deepest portion located at the deepest position toward the center is 1.0 mm or less. The uneven portion can also be provided on the susceptor 13G.

[0080] <Fourth embodiment> In this embodiment, an example in which the filler contains a magnetic material will be described.

[0081] Fig. 14 is a side view of the filler 11J. As shown in Fig. 14, the filler 11J has a region 11Ja and a region 11Jb (also referred to as a first region). The region 11Ja is made of a material that generates an aerosol when heated as described above as the filler. The region 11Jb is made of a magnetic material similar to the susceptor member 13. In other words, the filler 11J can be said to include a susceptor member (also referred to as a second susceptor member) different from the susceptor member 13.

[0082] The filler 11J includes a plurality of regions 11Jb. The filler 11J in this embodiment is formed by cutting out a sheet body into a rectangular shape. At this time, each region 11Jb is arranged at a predetermined interval. In this example, the regions 11Jb are arranged at a distance in the longitudinal direction D1. The intervals between the regions 11Jb do not have to be the same. When the filler 11J is configured in a long (rectangular) shape, it is preferable that the length of the filler 11J is approximately the same as the length of the filler accumulation body 10. The length of the filler 11J is preferably in the range of 10 mm to 25 mm, and more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such a filler 11J is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm. The shape, number, dimensions, and arrangement of the regions 11Ja and 11Jb are not limited to the example of FIG. 14, and can be set arbitrarily. The length of the region 11Jb in the longitudinal direction is preferably in the range of, for example, 1 mm to 24 mm.

[0083] Since the filler 11J has the region 11Jb containing a magnetic material, it is heated not only from the susceptor member 13 but also from the region 11Jb, so that thermal energy can be obtained stably. Therefore, by using this embodiment, the filler can be heated and aerosol can be generated stably. Note that it is also possible to use only the filler 11J as a susceptor without providing the susceptor member 13.

[0084] In this embodiment, the region 11Jb is arranged at a distance from the other region in the longitudinal direction D1, but the present invention is not limited to this. FIG. 15 is a side view of the filler 11K. As shown in FIG. 15, the filler 11K includes a region 11Ka formed of a material that generates an aerosol and a region 11Kb formed of a magnetic material. In this case, a plurality of regions 11Kb may be provided in a lattice shape. In this case, the shape, number, dimensions and arrangement of the regions 11Ka and 11Kb are not limited to the example of FIG. 15 and can be set arbitrarily. The longitudinal length of the region 11Kb is, for example, in the range of 1 to 24 mm, the length in the lateral direction D2 is, for example, 0.3 mm or less, and the length of the long side is, for example, 1.5 mm or less.

[0085] FIG. 16 is a side view of the filler 11L. As shown in FIG. 16, the filler 11L includes an area 11La formed of an aerosol-generating material and an area 11Lb formed of a magnetic material. In this case, the areas 11Lb may be provided in a dot shape, spaced apart at a predetermined interval. In this case, the shape, number, dimensions and arrangement of the areas 11Lb are not limited to the example in FIG. 16, and can be set arbitrarily. The areas 11Lb are, for example, granular in shape with a diameter of 0.3 mm or less.

[0086] FIG. 17 is a side view of the filler 11M. As shown in FIG. 17, the filler 11M includes a region 11Ma formed of an aerosol-generating material and a region 11Mb formed of a magnetic material. In this case, a plurality of regions 11Mb may be provided at intervals in the short-side direction D2. When the filler 11M is configured in a long (strip) shape, it is preferable that the length of the filler 11M is approximately the same as the length of the packing assembly 10. The length of the filler 11M is preferably in the range of 10 mm to 25 mm, and more preferably in the range of 10 mm to 20 mm. An example of the dimensions of such a filler 11M is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm. The shape, number, dimensions, and arrangement of the regions 11Ma and 11Mb are not limited to the example of FIG. 14, and can be set arbitrarily. It is preferable that the length of the region 11Mb in the long direction is equal to or less than the length of the filler 11M. In this case, the shape, number, dimensions and arrangement of the regions 11Ma and 11Mb can be set arbitrarily without being limited to the example in Fig. 17. It is preferable that the length of the short side direction D2 of the region 11Mb is, for example, 0.3 mm or less, and the length of the long side is 1.5 mm or less. EXAMPLES

[0087] The results of a heating experiment using a smoking article cartridge according to one embodiment of the present invention are shown below.

[0088] (1. Shape of susceptor material) The shapes of the susceptor members used in this example are shown below: The following susceptor members were inserted into the packing stack.

[0089] (1-1. Example 1) Shape of susceptor material: Cylindrical (pin-shaped) Susceptor material: Zinc-plated steel surface Quantity of susceptor parts: 1 Size of the susceptor: Length: 12.0 mm, diameter: 1.0 mm (volume 9.4 mm 3 ) Length of filling: 10~12mm

[0090] (1-2. Example 2) Shape of susceptor material: Cylindrical (pin-shaped) Susceptor material: Zinc-plated steel surface Quantity of susceptor parts: 2 pieces Size of the susceptor: Length: 12.0 mm, diameter: 0.55 mm (volume: 5.7 mm 3 ) Length of filling: 10~12mm

[0092] (1-4. Example 4) Shape of susceptor component: Plate shape (blade shape) Susceptor material: Nickel only Quantity of susceptor parts: 2 pieces Size of susceptor member: Length: 12.0mm, Width: 1.5mm, Thickness: 0.2mm (Volume 7.2mm 3 ) Length of filling: 10~12mm

[0095] The frequency of the alternating current used for induction heating in the induction heating device in the heating experiment was 450 kHz.

[0096] (Experimental Results) Table 1 shows the experimental results when a smoking device cartridge containing a filler accumulation was heated using the susceptor member described above. In Table 1, "◯" indicates that it was heated well. "×" indicates that it was not heated. "△" indicates that it was partially heated. [Table 1] (Table 1)

[0097] As shown in the results in Table 1, although the susceptor member was partially heated, the filler was not heated in Comparative Examples 1 and 2. On the other hand, in Examples 1 to 4 using one embodiment of the present invention, the susceptor member and the filler were heated well.

[0098] In other words, by using one embodiment of the present invention, the filling material can be stably heated, and an aerosol can be stably generated.

[0099] (Modification) It should be noted that within the scope of the concept of the present invention, a person skilled in the art may come up with various modifications and alterations, and it is understood that these modifications and alterations also fall within the scope of the present invention. For example, those in which a person skilled in the art appropriately adds, deletes, or modifies the design of the above-mentioned embodiments, or adds, omits, or modifies the conditions of steps, are also included in the scope of the present invention as long as they include the gist of the present invention.

[0100] In the first embodiment of the present invention, the long-shaped filler has been described, but the present invention is not limited thereto, and the filler may have various shapes. For example, the filler may be formed in a paste form or a granular form. In this case, a lid may be provided on the end face of the smoking accessory cartridge.

[0101] The cartridge for a smoking article may also be provided with a cooling region between the packing material and the filter in the longitudinal direction.

[0102] In each embodiment of the present invention, an example in which different magnetic materials are used for the multiple susceptor members has been shown. In this case, the control device 51 may include a sensor for detecting the material and a thermometer for measuring the temperature. For example, the sensor may detect whether the material is a ferromagnetic material, a paramagnetic material, or a diamagnetic material. Alternatively, the sensor may detect the specific material of the susceptor member 13. The control device 50 may control the heating temperature of the filler 11 by controlling the current (power) applied to the coil 55 according to the detected material.

[0103] <Fifth embodiment> In this embodiment, a cylindrical susceptor member will be described. For ease of explanation, the drawings will not show any components other than the susceptor member.

[0104] Fig. 18(A) is a schematic perspective view of the susceptor member 13L as viewed from the front right side. Fig. 18(B) is a schematic front view of the susceptor member 13L. As shown in Fig. 18(A) and Fig. 18(B), the susceptor member 13L has a cylindrical (hollow) shape. Furthermore, the susceptor member 13L has a gap 13Ls in a portion (in the longitudinal direction) when viewed from the front.

[0105] Also, the susceptor member 13L can be manufactured by winding a plate-like conductive member 13La (for example, a rectangular thin metal plate) having a certain thickness into a cylindrical shape around a core material. The thickness of the conductive member 13La is preferably 0.1 mm or more. In this example, the thickness of the conductive member 13La is 0.2 mm. The width of the conductive member 13La is preferably 1.5 mm or more. In this example, the width of the conductive member 13La is 4 mm. The length of the conductive member 13La is preferably greater than 9 mm. The outer diameter of the cylindrical shape of the susceptor member 13L can be set arbitrarily within a range of 1 mm or more and less than 7.5 mm, preferably within a range of 3 mm or more and 7 mm or less. The susceptor member 13L may be molded by die molding on a plate-like member.

[0106] Since the susceptor member 13L has a cylindrical shape, the filler is placed on the outside and inside of the susceptor member 13L, so that the contact area with the filler is increased. Also, since the susceptor member 13L has a cylindrical shape, the distance D from the coil (coil 55) which is the heating member to the susceptor member 13L becomes uniform. This enhances the heating function of the filler. Therefore, the filler can be sufficiently heated, and smoking can be enjoyed for a long time.

[0107] The susceptor member 13L does not necessarily have to have the gap 13Ls. For example, when the plate-shaped conductive member 13La is wound into a cylindrical shape, a part of the conductive member 13La may overlap. In this case, the overlapping part may be adhered.

[0108] FIG. 19(A) is a schematic perspective view of the susceptor member 13M as viewed from the front right side. FIG. 19(B) is a schematic front view of the susceptor member 13M. As shown in FIG. 19(A) and FIG. 19(B), the susceptor 13M has a cylindrical shape, and the end 13Mae is folded toward the inside of the cylinder when viewed from the front. The susceptor member 13M is manufactured by rolling a thin plate-like conductive member 13Ma into a cylindrical shape and folding the end 13Mae toward the inside of the cylinder. This ensures safety in the event that the susceptor member is swallowed by mistake or when the susceptor member protrudes from the cartridge.

[0109] 20(A), (B), and (C) are schematic perspective views of the susceptor member 13N as viewed from the right side of the front. As shown in FIG. 20(A), (B), and (C), the susceptor member 13N is composed of a plate-like conductive member 13Na having a cylindrical shape, and may have irregularities on its surface. More specifically, as shown in FIG. 20(A), the susceptor member 13N has a plurality of rectangular recesses 13Nb. As shown in FIG. 20(B), the susceptor member 13N has a plurality of rectangular protrusions 13Nc. As shown in FIG. 20(C), the susceptor member 13N has a plurality of rectangular recesses 13Nb and protrusions 13Nc. The susceptor member 13N can be manufactured by forming recesses or protrusions on a large plate-like conductive material by roll pressing, cutting it to a desired size, and rolling it into a cylindrical shape. The unevenness is not limited to the rectangular shape described above, but may be a triangle, a square, or any other polygon (including those with acute angles, obtuse angles, and angles of 180 degrees or more).

[0110] 21(A), (B) and (C) are schematic perspective views of the susceptor member 13P as viewed from the right side of the front. As shown in FIG. 21(A), (B) and (C), the susceptor member 13P may have a hemispherical unevenness on the surface. More specifically, as shown in FIG. 20(A), the susceptor member 13P has a plurality of hemispherical recesses 13Pb. As shown in FIG. 20(B), the susceptor member 13P has a plurality of hemispherical protrusions 13Pc. As shown in FIG. 20(C), the susceptor member 13P has a plurality of hemispherical recesses 13Pb and protrusions 13Pc. The susceptor member 13P can be manufactured by forming hemispherical recesses or protrusions on a large plate-shaped conductive material 13Pa by roll pressing, cutting it to a desired size, and rolling it into a cylindrical shape. Note that this embodiment is not limited to hemispherical unevenness, and may be applied to any shape that is elliptical or has a circular arc when viewed from above.

[0111] FIG. 22 is a schematic perspective view of the susceptor member 13Q as viewed from the right side of the front. As shown in FIG. 22, the susceptor member 13Q is composed of a plate-like conductive member 13Qa having a cylindrical shape, and may have a plurality of holes 13Qb (round holes in this example). The plurality of holes 13Qb may be arranged regularly or irregularly. The susceptor member 13Q can be manufactured by drilling a plurality of holes in a large plate-like conductive material 13Qa, cutting it to a desired size, and rolling it into a cylindrical shape. In this embodiment, the shape of the holes is not limited to round holes, and may be a triangle, a square, or another polygon (including those having obtuse angles, acute angles, and angles of 180 degrees or more).

[0112] FIG. 23(A) is a schematic perspective view of the susceptor member 13R as viewed from the front right side. FIG. 23(B) is a schematic front view of the susceptor member 13R. As shown in FIG. 23(A) and FIG. 23(B), the susceptor member 13R may have a cylindrical shape using two thin plate-shaped conductive members 13Ra. Specifically, in the susceptor member 13R, one plate-shaped conductive member 13Ra-1 is processed to have an upper semicircle when viewed from the front. The other plate-shaped conductive member 13Ra-2 is processed to have a lower semicircle when viewed from the front. In this embodiment, an example having two plate-shaped conductive members is shown, but the present invention is not limited to this. For example, three or more plate-shaped conductive members may be used.

[0113] Sixth Embodiment In this embodiment, a susceptor member having a cylindrical shape different from that in the fifth embodiment will be described. Specifically, a susceptor member formed by rolling up a net-like material will be described.

[0114] FIG. 24(A) is a side view of the susceptor member 13S. FIG. 24(B) is a schematic perspective view of the susceptor member 13S as viewed from the front right side. As shown in FIG. 24(A) and FIG. 24(B), the susceptor member 13S may have a cylindrical shape and be composed of a mesh-like material 13Sa having a mesh. The susceptor member 13S is formed by rolling a thin mesh-like conductive member (mesh-like material) into a cylindrical shape. The thickness of the mesh-like conductive member is preferably 0.1 mm or more. In this example, the thickness of the mesh-like conductive member is 0.2 mm. The width of the mesh-like conductive member is preferably 1.5 mm or more. In this example, the width of the mesh-like conductive member is 4 mm. The length of the mesh-like conductive member 13S is preferably greater than 9 mm. The outer diameter of the cylinder of the susceptor member 13S can be set arbitrarily within a range of 1 mm or more and less than 7.5 mm, preferably within a range of 3 mm or more and 7 mm or less.

[0115] The susceptor member 13S has a cylindrical mesh shape, and therefore the heating efficiency of the wires constituting the mesh is higher than that of a plate-like material. This allows for moderate heating and reduces the air flow (difficulty in inhaling) when smoking, allowing you to enjoy smoking for a long period of time.

[0116] Seventh embodiment In this embodiment, a susceptor member having a cylindrical shape different from those in the fifth and sixth embodiments will be described. Specifically, a susceptor member formed by winding a wire into a cylindrical shape will be described.

[0117] Fig. 25(A) is a schematic front view of the susceptor member 13T. Fig. 25(B) is a schematic side view of the susceptor member 13T. As shown in Figs. 25(A) and 25(B), the susceptor member 13T has a cylindrical shape, and the cylindrical shape may be composed of a wire 13Ta provided in a spiral shape. In addition, in the susceptor member 13T, the wire 13Ta provided in a spiral shape is wound without gaps. In this example, the end of the wire 13Ta extends in the vertical direction, but it may extend in the winding direction or toward the inside of the cylinder.

[0118] Fig. 26(A) is a schematic front view of the susceptor member 13U. Fig. 26(B) is a schematic side view of the susceptor member 13U. As shown in Fig. 26(A) and Fig. 26(B), the susceptor member 13U has a cylindrical shape, and the cylindrical shape may be formed of a wire 13Ua provided in a spiral shape. In the susceptor member 13U, the wire 13Ua provided in a spiral shape is wound with gaps 13Us.

[0119] The susceptor members 13T and 13U can be manufactured by winding a single wire around a cylindrical core material and then removing the core material. At this time, the susceptor member 13T is manufactured by winding the wire without any gaps, and the susceptor member 13U is manufactured by winding the wire with gaps. The susceptor member 13U may be formed by forming the susceptor member 13T and then extending it from both ends.

[0120] In this embodiment, the susceptor member 13T has a large number of turns (high density, high space factor) because the wire is wound with no gaps, making it possible to suppress heat dissipation and heat the filler at a high temperature. On the other hand, the susceptor member 13U has a small number of turns (low density, low space factor) because the wire is wound with gaps, making it possible to dissipate heat more easily and lower the heating temperature. In other words, the heating temperature of the filler can be adjusted according to the gaps (density, space factor) of the wire. Therefore, by using this embodiment, the filler can be heated at an optimal temperature.

[0121] In this embodiment, an example in which the wire is composed of one wire has been shown, but the present invention is not limited to this. FIG. 27(A) is a schematic front view of the susceptor member 13V. FIG. 27(B) is a schematic side view of the susceptor member 13V. As shown in FIG. 27(A) and FIG. 27(B), the susceptor member 13V has a cylindrical shape, and the cylindrical shape may be composed of a wire 13Va provided in a spiral shape. Furthermore, the wire 13Va has a first wire 13Va1 and a second wire 13Va2. The first wire 13Va1 corresponds to a core material. The second wire 13Va2 is provided so as to cover the first wire 13Va in a spiral shape. The second wire 13Va2 is thinner than the first wire 13Va1. The wire 13Va can also be called a Clapton wire. In this embodiment, the wire 13Va may be a wire having two core wires (first wires) (fused Clapton wire) in addition to the above-mentioned Clapton wire, or may be a wire having no core wire (first wire) and having an outer coil stretched once (Allen Clapton wire). Also, the wire 13Va may be a wire (staggered Clapton wire) in which two Clapton wires are wound with an outer coil (second wire) wound with equal gaps between them, and a new wire (third wire) is wound around the gaps. Also, the above-mentioned wires may be wound with gaps between them.

[0122] Eighth embodiment In this embodiment, a susceptor member different from that in the third embodiment will be described. Specifically, a susceptor member provided by intersecting a plurality of plate-like members will be described.

[0123] FIG. 28(A) is a schematic perspective view of the susceptor member 13W as viewed from the front right side. FIG. 28(B) is a schematic front view of the susceptor member 13W. As shown in FIG. 28(A) and FIG. 28(B), the susceptor member 13W has two plate-shaped conductive members 13Wa, specifically, a plate-shaped conductive member 13Wa1 (first plate-shaped conductive member) and a plate-shaped conductive member 13Wa2 (second plate-shaped conductive member). The conductive members 13Wa1 and 13Wa2 are arranged to cross each other. The thickness of the conductive member is preferably 0.1 mm or more. In this example, the thickness of the conductive member is 0.2 mm. The width of the conductive member is preferably 1.5 mm or more. In this example, the width of the conductive member is 4 mm. The length of the conductive member 13L is preferably greater than 9 mm. The outer diameter of the cylindrical susceptor member 13L can be set arbitrarily within the range of 1 mm or more and less than 7.5 mm, preferably within the range of 3 mm or more and 7 mm or less. The width and length of the two conductive members may be different from each other.

[0124] 28(C), the susceptor member 13W is formed by forming notches 13Wak in two plate-shaped conductive members (metal pieces) 13Wa and combining them. By using this embodiment, the filler can be heated by twice the area compared to the case where one plate-shaped susceptor member is used.

[0125] FIG. 29(A) is a schematic perspective view of the susceptor member 13WW as viewed from the front right side. FIG. 29(B) is a schematic front view of the susceptor member 13WW. As shown in FIG. 29(A) and FIG. 29(B), in the susceptor member 13WW, the two plate-shaped conductive members 13WWa may be bent. In this case, the width and length of the two plate-shaped conductive members may be different from each other. This increases the area of ​​the susceptor member, so that the filler can be heated more efficiently. Therefore, the filler can be sufficiently heated, and smoking can be enjoyed for a long time.

[0126] In this embodiment, an example in which two plate-shaped conductive members are combined is shown, but the present invention is not limited to this. Fig. 30(A) is a schematic perspective view of the susceptor member 13X as viewed from the front right side. Fig. 30(B) is a schematic front view of the susceptor member 13X. As shown in Figs. 30(A) and 30(B), four plate-shaped conductive members 13Xa may be combined in the susceptor member 13X. In this case, the widths and lengths of the four plate-shaped conductive members may be different from each other.

[0127] FIG. 31(A) is a schematic perspective view of the susceptor member 13Y as viewed from the front right side. FIG. 31(B) is a schematic front view of the susceptor member 13Y. As shown in FIG. 31(A) and FIG. 31(B), in the susceptor member 13Y, three plate-shaped conductive members may be combined and the ends may be bent. In this case, the widths and lengths of the three plate-shaped conductive members may be different from each other. By using this embodiment, the area of ​​the susceptor member becomes larger, so that the filler can be heated more efficiently. The susceptor member may be formed by combining five or more plate-shaped conductive members.

[0128] In each embodiment of the present invention, an example is shown in which a metal member is rolled into a cylindrical shape as a plate-shaped conductive member when forming a susceptor, but the present invention is not limited to this. Fig. 32 is a schematic top view of a graphene sheet 130. As shown in Fig. 32, when a graphene sheet is used as a plate-shaped conductive member, the filler can be effectively heated due to its high conductivity, and the weight of the susceptor can be reduced.

[0129] Ninth embodiment In the present embodiment, susceptor members and smoking article cartridges having different shapes are described.

[0130] Fig. 33 is a schematic cross-sectional view of a smoking article cartridge 1Z having a filler accumulation 10 in this embodiment. As shown in Fig. 33(A), the smoking article cartridge 1Z may include a filler accumulation 10, a filter 30, a lid 45, and a sheet-like outer packaging member 40. In addition, in the smoking article cartridge 1Z, if the outer packaging member 40 has a certain strength, a hollow portion 35 may be provided between the filler accumulation 10 and the filter 30 without providing a support member 20. The lid 45 may be provided on an end face of the smoking article cartridge 1Z.

[0131] (Configuration of susceptor 13Z) FIG. 33(B) is a schematic perspective view of the susceptor member 13Z. As shown in FIG. 33(A) and FIG. 33(B), the susceptor member 13Z has a crown shape having a cylindrical portion 13Za and a plurality of projections and recesses 13Zb (six pointed projections in this example) on one side. The susceptor member 13Z can be manufactured by cutting a large plate-shaped conductive material 13Pa so as to form a plurality of projections and recesses on one side and rolling it into a cylindrical shape. The thickness of the conductive member is preferably 0.1 mm or more. In this example, the thickness of the conductive member is 0.2 mm. The width of the conductive member is preferably 1.5 mm or more. In this example, the width of the conductive member is 4 mm. The length of the conductive member 13L is preferably greater than 9 mm. The outer diameter of the cylindrical shape of the susceptor member 13L can be set arbitrarily within a range of 1 mm or more and less than 7.5 mm, preferably within a range of 3 mm or more and 7 mm or less.

[0132] In the case of the susceptor 13Z, the cylindrical portion 13Za allows the heating area of ​​the filler to be increased. The shape of the irregularities 13Zb is not limited to the shape shown in Fig. 33(B), and each of the irregularities 13Zb may have a different length, the tip of the irregularities 13Zb may be circular, or the number of the irregularities 13Zb may be a number other than six. In other words, the heating condition of the filler can be adjusted by adjusting the shape of the irregularities.

[0133] In addition, although Fig. 33(A) shows an example in which one susceptor member 13Z is provided, the present invention is not limited to this. As shown in Fig. 33(C), a plurality of susceptor members 13Z may be provided. In this case, the susceptor members 13Z may be arranged so that the sides of the susceptor members 13Z having the irregularities 13Za face each other, or may be arranged so that they face the same direction.
