Summary of the Invention

Problems to be Solved by the Invention

[0004] In the aerosol generating article (smoking device cartridge) described in Patent Document 1, the susceptor is positioned along the radial central axis within the aerosol-forming substrate (heated substrate). Therefore, during the manufacturing of the smoking device cartridge, it is necessary to hold the susceptor so that it does not shift from the center of the heated substrate. Furthermore, since the heated substrate is made of a relatively soft material, while the susceptor material contained in the susceptor is a metal such as stainless steel or nickel, when manufacturing by cutting a long susceptor positioned at the center of a long heated substrate to the desired length, it is necessary to cut the relatively hard susceptor while preventing the end faces of the relatively soft heated substrate from being crushed. Thus, the manufacturing process for the smoking device cartridge described in Patent Document 1 becomes complicated, potentially reducing manufacturing efficiency.

[0005] Therefore, this disclosure aims to provide a cartridge for smoking accessories that can suppress the decrease in manufacturing efficiency. [Means for solving the problem]

Modes for Carrying Out the Invention

[0017] Hereinafter, an embodiment of the present invention will be described based on the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and duplicate descriptions are omitted. Also, the dimensional ratios in the drawings are merely examples and are not limited thereto. Further, for the sake of explanation, there may be cases where it is exaggerated partially. Also, in each figure, the left side will be described as one side in the longitudinal direction, and the right side will be described as the other side in the longitudinal direction.

[0018] Also, in this specification, "smoking" generally often means inhaling smoke containing nicotine, tar, etc. generated by burning or heating tobacco leaves of the genus Nicotiana of the Solanaceae family or a material containing tobacco components, but here, it simply means "enjoying smoke", "tasting smoke", "appreciating smoke", and the aromatic components that are the source of the smoke are not limited to tobacco materials and are also applicable to those using non-tobacco materials.

[0019] FIG. 1 is a diagram showing an example of a usage mode of the cartridge 1 for a smoking device according to the present disclosure.

[0020] As shown in FIG. 1, the cartridge 1 for a smoking device according to the present disclosure can be smoked using the smoking device 100. The smoking device 100 is a smoking device that inductively heats the cartridge 1 for a smoking device using an induction magnetic field (a magnetic field generated by electromagnetic induction). The smoking device 100 includes an insertion portion 101 for inserting the cartridge 1 for a smoking device, an induction heating coil 102 disposed inside the insertion portion 101, and a control portion 103 including a control device (not shown) for the induction heating coil 102, a battery (not shown), and the like. The induction heating coil 102 is disposed so as to surround the cartridge 1 for a smoking device inserted into the insertion portion 101, and generates an induction magnetic field when an electric current flows therethrough.

[0021] FIG. 2 is an external view of the cartridge 10 for a smoking device according to the first embodiment of the present invention. FIG. 3 is a cross-sectional view taken along the arrow III-III in FIG. 2. The white arrow in FIG. 3 schematically indicates the direction in which air enters during suction.

[0022] As shown in FIGS. 2 and 3, the cartridge 10 for a smoking device according to the first embodiment of the present invention includes a cylindrical skeleton material 11 and a heated base material 12 that generates an aerosol by heating, and is formed in a columnar shape. In the present embodiment, the cartridge 10 for a smoking device further includes a filter 13 and a seal member 20.

[0023] The skeletal material 11 is a component that constitutes the exoskeleton of the smoking device cartridge 10, and is formed in a cylindrical shape that partitions the internal space 16 extending from one side (right side in Figure 3) to the other side (left side in Figure 3) in the longitudinal direction. The skeletal material 11 is formed in a cylindrical shape by winding a plurality of sheets 14, 15 (two in this embodiment). In this embodiment, the skeletal material 11 is formed in a cylindrical shape by spirally winding two sheets 14, 15 in a direction inclined with respect to the longitudinal direction. The heating substrate 12 is placed in the region on one side of the internal space 16 of the skeletal material 11 (the region on one side of the center in the longitudinal direction). A sealing member 20 is placed at the end of the internal space 16 of the skeletal material 11 on one side. A filter 13 is placed at the end of the internal space 16 of the skeletal material 11 on the other side. The length of the skeletal material 11 is preferably 30 mm or more and 80 mm or less. The diameter of the frame material 11 is preferably 4.0 mm or more and 9.0 mm or less, and more preferably 5.0 mm or more and 8.0 mm or less from the viewpoint of ease of handling by the user.

[0024] The skeletal material 11 has a first region 17 formed by the first sheet 14 of the two sheets 14 and 15, and a second region 18 formed by the second sheet 15. The first region 17 and the second region 18 are adjacent to each other and are arranged in a spiral shape inclined with respect to the longitudinal direction. That is, the skeletal material 11 has a first region 17 and a second region 18 which are different regions in the longitudinal direction. The widthwise ends of each sheet 14 and 15 are bonded to each other in an overlapping state. The width (length in the longitudinal direction) of the overlapping portion 21 of each sheet 14 and 15 is narrower than the width of the non-overlapping portion of each sheet 14 and 15. In the overlapping portion 21, the sheet on one side is located on the outer diameter side (outer in the radial direction) than the sheet on the other side. For example, in the overlapping portion 21 of the enlarged part of Figure 3, the second sheet 15 on one side is located on the outer diameter side than the first sheet 14 on the other side.

[0025] The two sheets 14 and 15 are sheets with different properties, and as a result, the first region 17 and the second region 18 of the skeletal material 11 have different properties. The two sheets 14 and 15 have relatively high strength so as to constitute the exoskeleton of the smoking device cartridge 10 when the skeletal material 11 is formed.

[0026] The first sheet 14 is a layered sheet (in this embodiment, two layers), having a first layer 14a on the inner diameter side (inner side in the radial direction) and a second layer 14b on the outer diameter side. The first layer 14a of the first sheet 14 contains a susceptor material that generates heat due to an induced magnetic field. That is, the skeletal material 11 has a heat-generating section 22 containing a susceptor material that generates heat due to a predetermined induced magnetic field, and in this embodiment, this heat-generating section 22 is provided in a first region 17 formed by the first sheet 14. The second layer 14b of the first sheet 14 is paper. The first sheet 14 may be formed, for example, by laminating a thin film of susceptor material to one side of paper (the side that becomes the inner diameter side). Thus, in this embodiment, the entire first region 17 of the skeletal material 11 functions as a heat-generating section 22 containing a susceptor material that generates heat due to an induced magnetic field. In this respect, the heat-generating section 22 may be called a susceptor. In this embodiment, the first region 17 and the second region 18 are arranged adjacent to each other in a spiral shape inclined with respect to the longitudinal direction. Therefore, the first region 17 formed by the first sheet 14 is provided in a spiral shape continuously from one side to the other of the skeletal material 11. That is, the first region 17 of the skeletal material 11, which functions as a heating element 22, is located at a position that overlaps the substrate 12 to be heated from the outside in the radial direction.

[0027] Examples of susceptor materials include iron, stainless steel, nickel, brass, titanium, aluminum, copper, Co, chromium, FeOFe2O3, NiOFe2O3, CuOFe2O3, MgOFe2O3, MnBi, MnSb, MnOFe2O3, Y3Fe5O12, CrO2, MnAs, Gd, Dy, and carbon materials (e.g., carbon, graphite). Preferred materials include magnetic iron, ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, or metal materials combining these. Particularly preferred are alloys of ferromagnetic iron, paramagnetic aluminum, and ferrodiamagnetic chromium, or multiple layers of these materials.

[0028] The second sheet 15 is a paper sheet that does not contain susceptor material and has higher breathability than the first sheet 14. The breathability of the second sheet 15 may be ensured, for example, by providing minute pores. Thus, the first region 17 and the second region 18 of the skeletal material 11 have different breathability properties. In this embodiment, the first region 17 has heat-generating properties that generate heat in a predetermined induced magnetic field, while the second region 18 does not generate heat. Furthermore, the second region 18 has higher breathability than the first region 17.

[0029] The inner surface of the skeletal material 11 may be coated or impregnated with a fragrance material. The fragrance material is not particularly limited as long as it is one that is generally used in smoking cartridges 10, and examples include tobacco extract, vanillin, chocolate, cocoa, menthol, etc.

[0030] The method for manufacturing the skeletal material 11 is, for example, to form a cylindrical shape by spirally winding two sheets 14 and 15 in a direction inclined with respect to the longitudinal direction around a cylindrical temporary core member (not shown) so that the two sheets 14 and 15 are arranged alternately in the longitudinal direction. Next, the two cylindrical sheets 14 and 15 are removed from the temporary core member and cut to the desired length to manufacture the skeletal material 11. Note that the two sheets 14 and 15 may be bonded together in the width direction before being wound around the temporary core member to form a single sheet. Alternatively, the two sheets 14 and 15 may be bonded together in the width direction while being wound around the temporary core member.

[0031] The heated substrate 12 is a component that generates an aerosol when heated, and is filled into the other end of the internal space 16 of the skeletal material 11 in the longitudinal direction and supported by the skeletal material 11. The heated substrate 12 may have the form of a paste body obtained by drying a paste-like substance (hereinafter simply referred to as "paste body"), a strip-shaped form extending in the longitudinal direction, a sheet-shaped form, a chip-shaped form, a wood chip-shaped form, or a powder-like form (including powder, fine granules, fine particles and granules).

[0032] When the substrate to be heated 12 is in the form of strips, its width is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.2 mm or more and 0.8 mm or less. When the substrate to be heated 12 is in the form of a sheet, its thickness is preferably 0.1 mm or more and 1.0 mm or less, and more preferably 0.1 mm or more and 0.5 mm or less. Furthermore, when the substrate to be heated 12 is in the form of granules, its average diameter is preferably 0.1 mm or more and 3.0 mm or less, and more preferably 0.4 mm or more and 0.8 mm or less.

[0033] Examples of methods for preparing the heated substrate 12 include mixing tobacco material and / or non-tobacco material with an aerosol former that generates aerosols, microcrystalline cellulose, flavoring additives, preservatives, adhesives, thickeners, etc., and then forming it into a rod shape by passing it through an orifice or nozzle under pressure; forming the composition for the heated substrate 12 into a thin sheet and then cutting it; or drying and pulverizing the composition for the heated substrate 12 to form granules.

[0034] Aerosol formers are compounds or mixtures of compounds that vaporize or atomize upon heating to generate aerosols. Examples of aerosol formers 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. Vegetable glycerin and propylene glycol are particularly preferred. These aerosol formers can be used individually or in mixtures of two or more.

[0035] The following are examples of non-tobacco materials (aromatic components that produce an aroma when heated) that form the heated substrate 12, but are not limited to these.

[0036] In this embodiment, any non-tobacco material other than tobacco can be used without any particular restrictions. Various parts of the plant can be used, such as roots (including bulbs, tubers, tubers, etc.), stems (corms, rhizomes, Jerusalem artichoke rhizomes), tubers, bark (including stem bark, tree bark, etc.), leaves, flowers (including petals, pistils, stamens, etc.), tree trunks and branches, etc.

Examples of stems include asparagus, bamboo shoots, Japanese angelica tree, radishes, and yacon.

[0038] The above-mentioned tubers or the plants listed below contain carbohydrates and are preferably used as at least a part of the material of the heating substrate 12. For example, starches include corn starch (corn), potato starch (potato), sweet potato starch (sweet potato), tapioca starch (tapioca), etc., and have been used as thickeners, stabilizers, etc. These starches can be improved by crosslinking to improve acid resistance, heat resistance, shear resistance, etc., by esterification and etherification to improve storage stability and accelerate gelatinization, etc., and by oxidation to improve transparency, film properties, and storage stability, etc.

[0053] The filter 13 is a component that allows the flow of aerosols from the heated substrate 12 while restricting the flow of detached material and dust from the heated substrate 12 to prevent the inhalation of such detached material. It is positioned at the other end of the internal space 16 of the skeletal material 11 and fitted into the skeletal material 11. That is, the heated substrate 12 is positioned on the side of the internal space 16 of the skeletal material 11 that is ahead of the filter 13. The filter 13 can be formed using, for example, a cellulose acetate filter. The filter 13 is positioned spaced apart from the heated substrate 12 to the other side. In this embodiment, nothing is positioned in the intermediate region 19 between the heated substrate 12 and the filter 13 within the internal space 16 of the skeletal material 11. The filter 13 inhales smoke and aromatic components of the aerosol, allowing the user to enjoy a more comfortable smoking experience. The filter 13 may have a plurality of holes (not shown) formed at equal intervals along the circumferential direction to make it easier for the user to inhale the aerosols. Furthermore, in this embodiment, nothing is placed in the intermediate region 19 between the heated substrate 12 and the filter 13, but this is not limited to this. For example, support members that support the heated substrate 12, the filter 13, or the skeletal material 11 may be placed in the intermediate region 19.

[0054] The length of the filter 13 is preferably 3% to 60% of the total length of the smoking device cartridge 10, and more preferably 5% to 30%. By setting the length of the filter 13 to 3% to 60% of the total length of the smoking device cartridge 10, the filter 13 can generate sufficient aromatic components while maintaining breathability. Furthermore, by setting the length of the filter 13 to 5% to 30% of the total length of the smoking device cartridge 10, the frame material 11 can properly support the filter 13. When the length of the filter 13 is 3% to 10% of the total length of the smoking device cartridge 10, it is preferable to bond the filter 13 to one end of the frame material 11.

[0055] The sealing member 20 is positioned on one side of the heated substrate 12 to prevent fragments of the heated substrate 12 from falling from the internal space 16 to that side.

[0056] In the smoking device cartridge 10 configured as described above, the skeletal material 11 has a heating section 22 containing a susceptor material that generates heat by a predetermined induced magnetic field. Therefore, unlike when the susceptor is placed inside the heated substrate 12, it is not necessary to position the susceptor at a desired location (for example, the center) on the heated substrate 12. Furthermore, the skeletal material 11 is a component that constitutes the exoskeleton of the smoking device cartridge 10 and has relatively high strength. Therefore, even though it has a heating section 22 containing a susceptor material, when cutting the skeletal material 11 in a long form (a state in which multiple skeletal materials 11 are continuous) to a desired length, it can be easily cut without worrying about crushing the skeletal material 11.

[0057] Thus, according to this embodiment, it is possible to suppress the decrease in manufacturing efficiency of the smoking accessory cartridge 10.

[0058] Furthermore, since the first region 17 and the second region 18 of the skeletal material 11 have different properties, the sheet constituting one region (in this embodiment, the first sheet 14 constituting the first region 17) ensures heat generation for heating the substrate to be heated 12, while the sheet constituting the other region (in this embodiment, the second sheet 15 constituting the second region 18) ensures breathability.

[0059] Furthermore, the second region 18 of the skeletal material 11 has higher breathability than the first region 17. Therefore, since breathability can be ensured in the second region 18 of the skeletal material 11, the suction force required when the user inhales the smoking device cartridge 10 can be reduced.

[0060] Furthermore, since the first region 17 is a heating element 22 that generates heat due to a predetermined induced magnetic field, when smoking the smoking device cartridge 10 using the smoking device 100, the heating element 22 generates heat due to the induced magnetic field generated by the induction heating coil 102 of the smoking device 100, thereby heating the substrate to be heated 12.

[0061] Furthermore, the skeletal material 11 is a component that makes up the exoskeleton of the smoking device cartridge 10, and since it has relatively high strength, it is not easily crushed. For this reason, unlike cylindrical outer materials formed from a single thin sheet (for example, a single thin sheet of paper), the management (storage, transport, etc.) of the skeletal material 11 is easy.

[0062] Furthermore, the skeletal material 11 is formed into a cylindrical shape by spirally winding two sheets 14 and 15 in a direction inclined with respect to the longitudinal direction. The widthwise ends of each sheet 14 and 15 are bonded to each other in an overlapping state. That is, the overlapping portion 21 of the two sheets 14 and 15 extends in a direction inclined with respect to the longitudinal direction of the smoking device cartridge 10. In this way, the overlapping portion 21 of the two bonded sheets 14 and 15 is provided in the circumferential direction of the smoking device cartridge 10, which allows the twisting or bending force applied by the user to be distributed, thereby improving the overall strength of the smoking device cartridge 10.

[0063] Furthermore, since the overlapping portion 21 of the two sheets 14 and 15 is arranged in a spiral shape, a spiral step can be created on the inner surface of the skeletal material 11. As a result, this step can create a smooth airflow of aerosol, improving the taste and aroma, and increasing the efficiency of exhalation.

[0064] Furthermore, in the overlap portion 21 of the two sheets 14 and 15, the sheet on one side is positioned on the outer diameter side than the sheet on the other side. Therefore, when inserting the smoking device cartridge 10 into the insertion portion 101 of the smoking device 100, it is possible to prevent the overlap portion 21 of the two sheets 14 and 15 from catching on the smoking device 100, and to prevent the sheet on the other side from peeling off.

[0065] Furthermore, the first sheet 14 forming the first region 17 is a layered sheet (in this embodiment, two layers), having a first layer 14a on the inner diameter side and a second layer 14b on the outer diameter side. The first layer 14a contains a susceptor material, and the second layer 14b is paper that does not contain a susceptor material. Therefore, when the first layer 14a generates heat due to the induced magnetic field, the heat generated on the outer diameter side can be suppressed by the second layer 14b.

[0066] In this embodiment, two sheets 14 and 15 were spirally wound in a direction inclined with respect to the longitudinal direction to form a cylindrical frame material 11. However, the direction in which the multiple sheets are wound is not limited to a direction inclined with respect to the longitudinal direction. For example, multiple sheets 14 and 15 may be arranged alternately in the longitudinal direction, and each sheet 14 and 15 may be wound (flat wound) in the circumferential direction so that each sheet 14 and 15 forms an annular shape. In this case, the first region 17 and the second region 18 of the frame material 11 are arranged alternately in the longitudinal direction, and at least one first region 17 is provided in a position that overlaps the substrate to be heated 12 from the outside in the radial direction so that the substrate to be heated 12 can be heated.

[0067] Furthermore, although a filter 13 is provided in the smoking device cartridge 10 in this embodiment, the filter 13 may not be provided. Also, although a sealing member 20 is provided in the smoking device cartridge 10 in this embodiment, the sealing member 20 may not be provided.

[0068] Furthermore, in this embodiment, in the overlap portion 21 of the two sheets 14 and 15, one sheet is positioned on the outer diameter side than the other sheet, but the embodiment is not limited to this.

[0069] Furthermore, in this embodiment, the first sheet 14 is formed in layers, with the first layer 14a containing a susceptor material and the second layer 14b not containing a susceptor material. However, the embodiment is not limited to this configuration, and for example, the first layer 14a and the second layer 14b may each contain different susceptor materials.

[0070] Furthermore, although the first sheet 14 is formed in layers in this embodiment, it is not limited to this, and for example, a single-layer first sheet 14 formed by kneading in a susceptor material may also be used.

[0071] Furthermore, in this embodiment, the air permeability of the first region 17 and the second region 18 of the skeletal material 11 is made different, but this is not limited to this, and the first region 17 and the second region 18 may have substantially the same air permeability. Even in this case, the first region 17 has the property of generating heat through induction heating, while the second region 18 does not, so their properties are different.

[0072] Next, a second embodiment of the present invention will be described with reference to the drawings. The smoking device cartridge 30 of this embodiment differs from the first embodiment in that both the first region 17 and the second region 18 of the skeletal material 11 are heating elements. Components similar to those of the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0073] Figure 4 is a cross-sectional view of a smoking device cartridge 30 according to a second embodiment of the present invention.

[0074] As shown in Figure 4, the smoking device cartridge 30 according to this embodiment comprises a cylindrical skeletal material 11 and a heated substrate 12 that generates an aerosol when heated, and is formed in a columnar shape.

[0075] The skeletal material 11 is formed into a cylindrical shape by winding multiple sheets (two in this embodiment) 31 and 32, and partitions an internal space 16 that extends in the longitudinal direction on the inside. In this embodiment, the skeletal material 11 is formed into a cylindrical shape by spirally winding two sheets 31 and 32 in a direction inclined with respect to the longitudinal direction.

[0076] The skeletal material 11 has a first region 17 formed by the first sheet 31 of the two sheets 31 and 32, and a second region 18 formed by the second sheet 32. The widthwise ends of each sheet 31 and 32 are bonded to each other in an overlapping state. The width (length in the longitudinal direction) of the overlapping portion 21 of each sheet 31 and 32 is narrower than the width of the non-overlapping portion of each sheet 31 and 32. In the overlapping portion 21, the sheet on one side is located on the outer diameter side (outer in the radial direction) than the sheet on the other side. For example, in the overlapping portion 21 of the enlarged part of Figure 4, the second sheet 32 ​​on one side is located on the outer diameter side than the first sheet 31 on the other side.

[0077] The first sheet 31 contains a first susceptor material that generates heat due to an induced magnetic field. The second sheet 32 ​​also contains a second susceptor material that generates heat due to an induced magnetic field. Specifically, the first region 17 is provided with a first heat-generating section 33a containing the first susceptor material that generates heat due to a predetermined induced magnetic field, and the second region 18 is provided with a second heat-generating section 33b containing the second susceptor material that generates heat due to a predetermined induced magnetic field. Thus, in this embodiment, both the first region 17 and the second region 18 of the skeletal material 11 are provided with heat-generating sections 33a and 33b containing susceptor material (first susceptor material and second susceptor material) that generates heat due to an induced magnetic field. In this respect, the heat-generating sections 33a and 33b may be referred to as susceptors. The first region 17 and the second region 18 of the skeletal material 11, which function as heat-generating sections 33a and 33b, are located at positions that overlap radially with respect to the substrate 12 from the outside. Furthermore, both the first sheet 31 and the second sheet 32 ​​may be single-layer sheets formed by kneading in susceptor material, or they may be formed in a layered manner having layers containing susceptor material, similar to the first sheet 14 in the first embodiment described above.

[0078] Examples of the first susceptor material include iron, stainless steel, ferritic iron, ferrite powder, ferrite particles, ferritic stainless steel, and ferromagnetic steel, with ferromagnetic iron and stainless steel being preferred. Examples of the second susceptor material include nickel, brass, titanium, aluminum, and chromium, with ferromagnetic nickel and diamagnetic chromium being preferred.

[0079] The Curie temperature of the second susceptor material is lower than that of the first susceptor material. For example, the Curie temperature of the first susceptor material is preferably 500°C to 1200°C, and the Curie temperature of the second susceptor material is preferably 180°C to 390°C. The second susceptor material may also have a Nail temperature lower than that of the first susceptor material. Specifically, the Curie temperature of the first susceptor material is preferably 500°C to 1200°C, and the Nail temperature of the second susceptor material is preferably 180°C to 390°C.

[0080] In the smoking device cartridge 30 configured as described above, heating sections 33a and 33b containing susceptor materials (first susceptor material and second susceptor material) that generate heat due to an induced magnetic field are provided in both the first region 17 and the second region 18 of the skeletal material 11, and the Curie temperature of the second susceptor material is lower than that of the first susceptor material. Therefore, the heating temperature of the heating sections 33a and 33b of the smoking device cartridge 30 can be controlled by the Curie temperature. For example, when an electric current is passed through the induction heating coil 102 of the smoking device 100 to generate an induced magnetic field, and heat is generated from the heating elements 33a and 33b in the first region 17 and the second region 18, if the second heating element 33b in the second region 18 reaches the Curie temperature of the second susceptor material and the ferromagnetism of the second heating element 33b is lost, the control unit 103 can stop the flow of current to the induction heating coil 102, thereby preventing any further temperature rise of the first heating element 33a in the first region 17.

[0081] Furthermore, since the smoking device cartridge 30 has heating sections 33a and 33b containing a susceptor material that generates heat due to a predetermined induced magnetic field, the decrease in manufacturing efficiency of the smoking device cartridge 30 can be suppressed, similar to the first embodiment described above.

[0082] Furthermore, in this embodiment, two sheets 31 and 32 were spirally wound in a direction inclined with respect to the longitudinal direction to form a cylindrical frame material 11. However, the direction in which the multiple sheets are wound is not limited to a direction inclined with respect to the longitudinal direction. For example, multiple first sheets 31 and second sheets 32 may be arranged alternately in the longitudinal direction, and each sheet 31 and 32 may be wound (flat wound) in the circumferential direction so that each sheet 31 and 32 forms an annular shape. In this case, multiple first regions 17 and second regions 18 of the frame material 11 are arranged alternately in the longitudinal direction, and at least the first region 17 is provided in a position that overlaps the substrate to be heated 12 from the outside in the radial direction so that the substrate to be heated 12 can be heated.

[0083] Next, a third embodiment of the present invention will be described with reference to the drawings. The smoking device cartridge 40 of this embodiment differs from the first embodiment in that the skeletal material 11 has three regions. Components similar to those of the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0084] Figure 5 is an external view of a smoking device cartridge 40 according to the fourth embodiment of the present invention. The cross-section of the smoking device cartridge 40 according to this embodiment is substantially the same as that of the first embodiment (see Figure 3), except for the skeletal material 11.

[0085] The smoking device cartridge 40 according to this embodiment comprises a cylindrical skeletal material 11 and a heated substrate 12 that generates an aerosol when heated, and is formed in a columnar shape.

[0086] As shown in Figure 5, the skeletal material 11 is formed into a cylindrical shape by winding together multiple sheets (three in this embodiment) 14, 15, and 41. In this embodiment, the skeletal material 11 is formed into a cylindrical shape by spirally winding together three sheets 14, 15, and 41 in a direction inclined with respect to the longitudinal direction.

[0087] The skeletal material 11 has a first region 17 formed by the first sheet 14 of the three sheets 14, 15, and 41, a second region 18 formed by the second sheet 15, and a third region 42 formed by the third sheet 41. In this embodiment, the first region 17, the second region 18, and the third region 42 are arranged adjacent to each other in a spiral shape inclined with respect to the longitudinal direction. The widthwise ends of each sheet 14, 15, and 41 are bonded to each other in an overlapping state. The width of the overlapping portions 21 on both sides of each sheet 14, 15, and 41 in the widthwise direction is narrower than the width of the non-overlapping portions of each sheet 14, 15, and 41. In the overlapping portions 21, the sheet on one side is located on the outer diameter side (radially outward) than the sheet on the other side.

[0088] The skeletal material 11 has a heat-generating section 22 containing a susceptor material that generates heat in a predetermined induced magnetic field, and this heat-generating section 22 is provided in a first region 17 formed by the first sheet 14. The second sheet 15 is a paper sheet that does not contain the susceptor material and has higher breathability than the first sheet 14. The third sheet 41 is a paper sheet different from the second sheet 15 and has even higher breathability than the second sheet 15. In other words, the first region 17, the second region 18, and the third region 42 of the skeletal material 11 have different properties from each other. In this embodiment, the third region 42 of the skeletal material 11 is a region with even higher breathability than the second region 18, but it is not limited to this, and the third region 42 may have different properties from both the first region 17 and the second region 18.

[0089] In the smoking device cartridge 40 configured as described above, there is a third region 42 having properties different from both the first region 17 and the second region 18. Therefore, by setting the properties of the third region 42 to desired properties, the skeletal material 11 can be given various performance characteristics.

[0090] Furthermore, since the smoking device cartridge 40 has a heating section 22 in which the skeletal material 11 contains a susceptor material that generates heat due to a predetermined induced magnetic field, a decrease in the manufacturing efficiency of the smoking device cartridge 40 can be suppressed, similar to the first embodiment described above.

[0091] In this embodiment, the three sheets 14, 15, and 41 were spirally wound in a direction inclined with respect to the longitudinal direction to form a cylindrical frame material 11. However, the direction in which the multiple sheets are wound is not limited to a direction inclined with respect to the longitudinal direction. For example, multiple sheets 14, 15, and 41 may be arranged alternately in the longitudinal direction, and each sheet 14, 15, and 41 may be wound (flat wound) in the circumferential direction so that each sheet 14, 15, and 41 forms an annular shape. In this case, the first region 17, the second region 18, and the third region 42 of the frame material 11 are arranged alternately in the longitudinal direction, and at least the first region 17 is provided in a position that overlaps the substrate material 12 radially from the outside so that the substrate material 12 to be heated can be heated.

[0092] Furthermore, in this embodiment, a third region 42 is provided in the skeletal material 11 in addition to the first region 17 and the second region 18, but the embodiment is not limited to this, and the skeletal material 11 only needs to have at least the first region 17 and the second region 18. For example, the skeletal material 11 may have four or more regions (regions with different properties from each other) including the first region 17 and the second region 18.

[0093] Next, a fourth embodiment of the present invention will be described with reference to the drawings. The smoking device cartridge 50 of this embodiment differs from the first embodiment in that the skeletal material 11 is formed from a single sheet 51. Components similar to those of the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0094] Figure 6 is a cross-sectional view of a smoking device cartridge 50 according to a fourth embodiment of the present invention.

[0095] As shown in Figure 6, the smoking device cartridge 50 according to this embodiment comprises a cylindrical skeletal material 11 and a heated substrate 12 that generates an aerosol when heated, and is formed in a columnar shape.

[0096] The skeletal material 11 is formed into a cylindrical shape by flat-winding a single sheet 51. The skeletal material 11 has a heat-generating portion 52 on one side of a predetermined position and a heat-generating suppression portion 53 on the other side of the predetermined position. That is, the skeletal material 11 has a first region 54 (heat-generating portion 52) and a second region 55 (heat-generating suppression portion 53) which are different regions in the longitudinal direction, and the first region 54 and the second region 55 have different properties from each other. In this embodiment, the heat-generating portion 52 of the first region 54 does not suppress heat generation toward the outer diameter side, and the heat-generating suppression portion 53 of the second region 55 has lower heat generation toward the outer diameter side than the first region 54. Thus, in this embodiment, the first region 54 and the second region 55 of the skeletal material 11 have different heat generation toward the outer diameter side.

[0097] The heating portion 52 of the first region 54 is a region of the sheet 51 that includes a susceptor material that generates heat by a predetermined induced magnetic field, and is positioned to overlap the heated substrate 12 from the outside in the radial direction. The same susceptor material as in the first embodiment can be used.

[0098] The heat-suppressing portion 53 of the second region 55 is a region that does not contain susceptor material that generates heat due to a predetermined induced magnetic field, and is the entire area on the other side of the frame material 11 from the predetermined position. In this embodiment, by not containing susceptor material, the heat generation toward the outer diameter side of the heat-suppressing portion 53 is kept lower than that of the first region 54.

[0099] In the smoking device cartridge 50 configured as described above, the skeletal material 11 has a heating section 52 containing a susceptor material that generates heat in a predetermined induced magnetic field. Therefore, similar to the first embodiment, a decrease in the manufacturing efficiency of the smoking device cartridge 50 can be suppressed.

[0100] Furthermore, the heating element 52 of the first region 54 of the skeletal material 11 includes a susceptor material and is positioned to overlap the substrate 12 to be heated from the outside in the radial direction, so that it can generate heat through the induced magnetic field and heat the substrate 12 to be heated.

[0101] Furthermore, the heat-suppressing portion 53 of the second region 55 of the skeletal material 11 covers the entire area on the other side of the skeletal material 11 beyond the predetermined position, and the heat generation toward the outer diameter is kept lower than that of the first region 54. Therefore, when inhaling the smoking device cartridge 50, the transfer of heat to the lips can be suppressed.

[0102] In this embodiment, a heating element 52 is provided in the first region 54 of the skeletal material 11, and the second region 55 is a region that does not contain susceptor material. However, the embodiment is not limited to this, and a heating element containing susceptor material that generates heat by a predetermined induced magnetic field may also be provided in the second region 55. In this case, for example, the second region 55 may function as a heat suppression element 53 by wrapping a sheet (such as paper) that can suppress heat generation toward the outer diameter side around the outer diameter side of the second region 55. In this case, the second region 55 does not suppress heat generation toward the inner diameter side, so it functions as a heating element, and also functions as a heat suppression element 53 that suppresses heat generation toward the outer diameter side. In this case, the Curie temperature of the susceptor material (second susceptor material) included in the second region 55 may be lower than the Curie temperature of the susceptor material (first susceptor material) included in the first region 54.

[0103] Furthermore, in this embodiment, the heat generation properties toward the outer diameter side of the first region 54 and the second region 55 of the skeletal material 11 are made to be different from each other. However, the embodiment is not limited to this, and for example, the air permeability of the first region 54 and the second region 55 may be made to be different from each other. Alternatively, both the heat generation properties toward the outer diameter side and the air permeability of the first region 54 and the second region 55 may be made to be different from each other.

[0104] Next, a fifth embodiment of the present invention will be described with reference to the drawings. The smoking device cartridge 60 of this embodiment differs from the first embodiment in that it includes a packaging material 61 that covers the outer circumference of the skeletal material 11. Components similar to those of the first embodiment are denoted by the same reference numerals and their descriptions are omitted.

[0105] Figure 7 is a cross-sectional view of a smoking device cartridge 60 according to a fifth embodiment of the present invention.

[0106] As shown in Figure 7, the smoking device cartridge 60 according to this embodiment comprises a cylindrical frame material 11, a heated substrate 12 that generates an aerosol when heated, and a packaging material 61 that covers the outer circumference of the frame material 11, and is formed in a columnar shape.

[0107] The skeletal material 11 has a heat-generating section 22 containing a susceptor material that generates heat in a predetermined induced magnetic field, and this heat-generating section 22 is provided in a first region 17 formed by the first sheet 14. The second sheet 15 is a paper sheet that does not contain the susceptor material.

[0108] The packaging material 61 is a decorative paper sheet intended to improve the design and strength of the smoking accessory cartridge 50, and is adhered to the outer surface of the frame material 11.

[0109] In the smoking device cartridge 60 configured as described above, the skeletal material 11 has a heating section 22 containing a susceptor material that generates heat in a predetermined induced magnetic field. Therefore, similar to the first embodiment, a decrease in the manufacturing efficiency of the smoking device cartridge 60 can be suppressed.

[0110] Furthermore, since the packaging material 61 covers the outer periphery of the skeletal material 11, the design and strength of the smoking device cartridge 60 can be improved by the packaging material 61. Next, another embodiment of the fifth embodiment will be described. In this other embodiment, the first sheet 14 contains iron, which is a ferromagnetic material, the second sheet 15 contains chromium, which is a ferrodiamagnetic material, and the packaging material 61 contains aluminum, which is a paramagnetic material. As a result, the smoking device cartridge 60 can efficiently transfer the heat from the iron to the chromium through the aluminum, and the smoking device 100 can heat the substrate to be heated 12 with the iron, and then use the chromium, which has received the heat from the iron transferred through the aluminum, to detect the temperature of the substrate to be heated 12 and control the heating.

[0111] In this embodiment, the skeletal material 11 covered by the packaging material 61 is formed from the first sheet 14 and the second sheet 15, but it is not limited to this. For example, as in the smoking device cartridge 50 according to the fourth embodiment, the skeletal material 11 formed into a cylindrical shape by flat-winding a single sheet 51 may be covered with the packaging material 61.

[0112] Although the present invention has been described above based on the above embodiments, the present invention is not limited to the contents of the above embodiments, and can naturally be modified as appropriate without departing from the present invention. In other words, all other embodiments, examples, and operational techniques made by those skilled in the art based on these embodiments are of course included in the scope of the present invention.
