Description

[Technical Field]

[0001] The present invention relates to a heated aerosol inhalation cartridge. [Background technology]

[0002] In recent years, tobacco products that use a method of heating a tobacco cartridge containing tobacco components and inhaling the vaporized tobacco components without using a flame have become widely known. In addition, due to the diversification of preferences, aerosol inhalation cartridges that use cartridge products that allow users to enjoy the aroma and flavor of plants that do not contain tobacco components, like cigarettes, without using a flame, are also becoming known.

[0003] Such an aerosol suction cartridge generates an aerosol by heating an aerosol-forming member in which a filler has been accumulated. Methods for heating the aerosol-forming member include (1) a method (resistance heating type) in which the aerosol suction cartridge is inserted into a heating blade installed inside a heating device and the heating blade is electrically heated to heat the filler (see, for example, Patent Document 1), and (2) a method (induction heating type) in which an induction heating member, which is a component mainly composed of a ferromagnetic material, is disposed inside the filler of the aerosol-forming member in advance, and an alternating magnetic field generated by the induction heating device generates hysteresis loss and Joule heat inside the induction heating member, thereby heating (induction heating) the filler (see, for example, Patent Document 2).

[0004] As shown in FIG. 11 , a conventional induction-heated aerosol suction cartridge 100 is used by inserting the upstream side of the aerosol airflow (i.e., the end opposite the mouthpiece) into an insertion port D1 provided in an induction heating device D. The inner diameter of the insertion port D1 is designed to fit appropriately with the outer diameter of the cylindrical aerosol suction cartridge 100, allowing for easy insertion and preventing easy removal during use. However, during the manufacture of the aerosol suction cartridge 100, individual differences in the outer diameter can result in the outer diameter being too small. In this case, saliva often causes the mouthpiece protection member to adhere to the mouth during use, leading to easy removal, which is a problem. On the other hand, while designing the outer diameter larger than the inner diameter of the insertion port D1 can certainly prevent removal during use, it may also prevent insertion before use. Therefore, it is preferable to set the outer diameter to the same as the inner diameter of the insertion port D1 during the design stage. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Special Publication No. 2015-519915 [Patent Document 2] Japanese Patent Publication No. 2021-175399 Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to provide an aerosol suction cartridge that fits snugly into the insertion port D1 of an induction heating device D and is difficult to remove from the insertion port D1. [Means for solving the problem]

[0007] In order to solve the above problem, the invention described in claim 1 is an aerosol suction cartridge having an overall cylindrical outer shape, and comprising one or more sheet-like outer diameter adjustment members on the outer surface or bottom surface of the cylindrical shape, a portion of the outer diameter adjustment member being fixed to the outer surface or bottom surface of the cylindrical shape and other portions being unfixed, and the outer diameter of the cylindrical shape being adjusted by adhering some or all of the other portions to the outer surface of the cylindrical shape starting from the fixed portion. The invention described in claim 2 is an aerosol suction cartridge described in claim 1, characterized in that at least one surface of the outer diameter adjustment member that is not fixed to the outer surface can be adhered to the cylindrical outer surface on part or all of the surface. The invention described in claim 3 is an aerosol suction cartridge described in either claim 1 or 2, characterized in that the outer diameter adjustment member has a rectangular, circular, polygonal, or combination thereof shape. The invention described in claim 4 is an aerosol suction cartridge characterized in that it has an overall cylindrical outer shape, and an outer diameter adjustment structure having a non-smooth shape is formed on part or all of the outer surface of the cylindrical shape, and the outer diameter adjustment structure is one of an uneven shape, a scaly shape, a short hair shape, or a combination of these. The invention described in claim 5 is an aerosol suction cartridge comprising: a cylindrical outer casing; and an outer diameter adjustment member housed within the tube of the outer casing for expanding the outer diameter of the outer casing; wherein the outer diameter adjustment member is made of an elastic material and has one or more protrusions on its outer periphery in a cross-sectional view perpendicular to the height direction of the outer casing; and wherein the length of a straight line starting from the apex of any one of the protrusions, passing through the center of the diameter of the outer casing, and ending at a point on the outer periphery is greater than the inner diameter of the outer casing when the outer diameter adjustment member is not housed. The invention described in claim 6 is an aerosol suction cartridge comprising: a cylindrical outer casing; a cylindrical mouthpiece connected to one end of the outer casing; and a sheet-shaped mouthpiece protection member wrapped around a portion of the outer circumferential surface of the outer casing and all or part of the outer circumferential surface of the mouthpiece, wherein the mouthpiece protection member has an outer diameter adjustment portion formed by expanding the sheet shape toward the upstream side of the aerosol of the outer casing, and the outer diameter adjustment portion is formed discontinuously along the circumferential direction perpendicular to the height direction of the outer casing. [Effects of the Invention]

[0008] According to the inventions described in claims 1 to 3, the outer diameter adjustment member is in close contact with the outer surface of the aerosol suction cartridge, i.e., the outer casing member or the mouthpiece protection member, thereby partially increasing the outer diameter of the aerosol suction cartridge, thereby enabling it to fit well into the insertion portion D1 of the induction heating device D and preventing it from coming loose during use.

[0009] According to the invention described in claim 4, the outer diameter adjustment structure partially increases the outer diameter of the aerosol suction cartridge or increases the friction between the outer surface and the insertion portion D1, so that it fits well into the insertion portion D1 of the induction heating device D and prevents it from coming loose during use.

[0010] According to the invention described in claim 5, the protrusion of the outer diameter adjustment member pushes the outer member from the inside, thereby partially increasing the outer diameter of the aerosol suction cartridge, so that it fits well into the insertion portion D1 of the induction heating device D and prevents it from coming loose during use.

[0011] According to the invention described in claim 6, the outer diameter adjustment portion is formed on the upstream side of the aerosol, and the outer diameter of the aerosol suction cartridge is partially enlarged, so that it fits well into the insertion portion D1 of the induction heating device D and can be prevented from coming loose during use.

[0013] The present invention will be described with reference to the accompanying drawings, in which the size, spacing, number and other details of the components of the drawings are greatly exaggerated or simplified compared to the actual objects in order to facilitate visibility and understanding.

[0014] Embodiment 1 FIG. 1 is a schematic side cross-sectional view of an aerosol suction cartridge 1 according to Embodiment 1, and FIG. 2 is a schematic perspective view. The aerosol suction cartridge 1 is formed into a cylindrical shape overall, with a sealing member 17, an aerosol-forming member 10, a support member 15, and a mouthpiece 14 linearly arranged. In Embodiment 1, the sealing member 17, the aerosol-forming member 10, and the support member 15 are housed in a cylindrical exterior member 16, the support member 15 side of the exterior member 16 is connected to one end of the mouthpiece 14, and the periphery of the connecting portion between the mouthpiece 14 and the exterior member 16 is enclosed and integrally connected with a sheet-like mouthpiece protection member 18 made of paper or resin, thereby forming an elongated cylindrical shape overall. Here, "elongated" means that, in a planar or three-dimensional shape, one dimension is longer than the other dimension. Furthermore, in this specification, an "elongated cylindrical shape (cylindrical shape)" means that the height of the cylinder (cylinder) (i.e., the component perpendicular to the base) is longer than the diameter of the circle that forms the base of the cylinder (cylinder). Hereinafter, the term "height direction (of the cylinder)" is synonymous with "longitudinal direction (of the cylinder)" or "direction perpendicular to the base (of the cylinder)."

[0015] In the first embodiment, one or more sheet-like outer diameter adjustment members 19 are provided on the outer surface or bottom surface of the cylindrical exterior member 16 or mouthpiece protection member 18. Here, the outer diameter adjustment members 19 are elongated rectangular sheets, a portion of which is adhered and fixed to the outer surface or the bottom surface on the upstream side of the exterior member 16, as shown in Fig. 2, and are members for adjusting the size of the outer diameter of the cylindrical shape by bringing part or all of the member into close contact with the outer surface of the cylindrical shape. The material of the outer diameter adjustment members 19 is preferably the same material as the exterior member 16 and mouthpiece protection member 18 (e.g., paper), and the thickness is preferably such that it can be easily deformed (e.g., 0.01 to 0.15 mm).

[0016] The exterior member 16 is formed from a flexible material such as paper or sheet-like resin, but when formed into a cylindrical shape, it is preferable that the exterior member 16 has a hardness sufficient to maintain the shape.

[0017] The aerosol suction cartridge 1 in the first embodiment is formed to have an outer diameter of, for example, 4.0 mm to 7.5 mm, more preferably 5.0 mm to 7.0 mm, and a length (in the longitudinal direction of the cylinder) of, for example, 40 mm to 80 mm. If the outer diameter of the aerosol suction cartridge 1 is set in the range of 6.5 to 7.5 mm, adjusting the outer diameter with the outer diameter adjusting member 19 allows the aerosol suction cartridge 1 to fit with an appropriate force into the insertion portion D1 provided in the induction heating device D, into which the aerosol suction cartridge 1 is inserted. This allows the aerosol suction cartridge 1 to be suitably held in the induction heating device, while facilitating the attachment and detachment of the aerosol suction cartridge 1. In this case, it is preferable to design the outer diameter before adjustment to be approximately 0.05 to 0.2 mm smaller than the inner diameter of the insertion portion D1, to ensure smooth insertion. Furthermore, if the length of the aerosol suction cartridge 1 is set to 40 mm or more, it will be longer than the length of the insertion portion D1 that receives the aerosol suction cartridge 1 provided in the induction heating device. Therefore, even when the aerosol suction cartridge 1 is inserted into the induction heating device, the suction nozzle can be exposed from the induction heating device, ensuring the length necessary for the user to inhale the aerosol.

[0018] In Fig. 2(a), one end of the outer diameter adjustment member 19a is bonded and fixed to the outer surface of the cylindrical shape, i.e., the outer surface of the exterior member 16, so that the longitudinal direction of the outer diameter adjustment member 19a faces a direction approximately perpendicular to the longitudinal direction of the cylindrical shape (i.e., the circumferential direction), while the remaining portions are not fixed and can be freely deformed. On the other hand, in Fig. 2(b), one end of the outer diameter adjustment member 19b is bonded and fixed to the bottom surface of the cylindrical shape, i.e., the bottom surface of the exterior member 16, so that the longitudinal direction of the outer diameter adjustment member 19b faces the longitudinal direction of the cylindrical shape, while the remaining portions are not fixed and can be freely deformed. Here, one end of the outer diameter adjustment member 19 may be fixed to the outer surface or bottom surface of the mouthpiece protection member 18, or the fixing may be limited to one end and may be a portion having a relatively large area.

[0019] As shown in FIG. 3, the outer diameter of the outer diameter adjustment member 19 is adjusted by starting from the fixed portion and adhering part or all of the remaining portion to the outer surface of the cylindrical exterior member 16 or mouthpiece protection member 18. For example, the outer diameter adjustment member 19a in FIG. 3(a) is adhered to the outer surface by wrapping it around the circumferential direction of the cylindrical shape, while the outer diameter adjustment member 19b in FIG. 3(b) is adhered to the outer surface by wrapping it along the longitudinal direction of the cylindrical shape. In this case, it is preferable that an adhesive be applied to part or all of at least one surface (the surface that is adhered to the outer surface) of the portion of the outer diameter adjustment member 18 that is not fixed to the outer surface so that it can be adhered to the outer surface of the cylindrical shape. Furthermore, the shape of the outer diameter adjustment member 19 is not limited to a rectangular shape and may be a circular shape, a polygonal shape, or a combination thereof. Furthermore, the entire outer diameter adjustment member 19 does not necessarily need to be tightly attached to the outer surface of the cylindrical exterior member 16 or mouthpiece protection member 18. If a sufficient effect is obtained with only a portion of the outer diameter adjustment member tightly attached, the remaining portion may be cut off and discarded. This allows for subtle adjustment of the outer diameter to accommodate individual differences during the manufacture of the aerosol suction cartridge 1. In this regard, it is preferable to form cut lines 19c1 and 19c2 on the outer diameter adjustment members 19a and 19b to facilitate cutting. The cut lines 19c1 and 19c2 are preferably perforated. From the perspective of facilitating adjustment of the outer diameter of the exterior member 16 or mouthpiece protection member 18, it is preferable to form the cut lines 19c1 and 19c2 perpendicular to the direction of wrapping around the cylindrical outer surface of the outer diameter adjustment member 19a and parallel to the longitudinal direction of the cylindrical shape of the outer diameter adjustment member 19b, but this is not limited thereto.

[0020] Another possible method for adjusting the outer diameter is to form an outer diameter adjustment structure 20 with a non-smooth shape on part or all of the cylindrical outer surface of the aerosol suction cartridge 1, as shown in FIG. 4. Here, the outer surface of the exterior member 16 is formed with an uneven shape (FIG. 4(a)), a scale-like shape (FIG. 4(b)), or a short hair-like shape (FIG. 4(c)). Here, multiple uneven outer diameter adjustment structures 20a are formed on the outer surface, and the outer diameter varies depending on the measurement location. However, the average value is preferably 4.0 mm to 7.5 mm, more preferably 5.0 mm to 7.0 mm, and the difference between the maximum and minimum values ​​is preferably 0.01 mm to 0.15 mm. The shape may be a rounded wave shape, a mountain shape, a stepped shape, a trapezoidal shape, or a triangular shape. The outer diameter adjustment structure 20a may be formed by machining (blasting, sanding, etc.) or laser processing.

[0021] The scale-shaped outer diameter adjustment structure 20b is formed by forming multiple scale-shaped structures on the outer surface of the outer casing member 16. The outer diameter adjustment structure 20b may be formed by processing the surface of the outer casing member 16 or by attaching a separate member. Surface processing can be achieved, for example, by cutting incisions into the outer surface of the outer casing member 16 with a thin cutter. Alternatively, attaching a separate member can be achieved by adhering a portion of a sheet-like material (preferably the same thickness and material as the outer diameter adjustment member 19) formed into a scale-like shape to the outer surface. In either of these methods, the outer diameter adjustment structure 20b is preferably fixed on the sealing member 17 side to the outer surface, while the mouthpiece 14 side is preferably unfixed and freely deformable. In FIG. 4(b), it is preferable that the sealing member 17 side (wide portion) is integrated with the outer surface of the outer casing member 16 and the mouthpiece 16 side (narrow portion) is unfixed, since this provides no resistance when inserted into the insertion port D1 of the induction heating device D but resistance when removed, making it less likely to come off during use.

[0022] In the case of the short-haired outer diameter adjusting structure 20c, multiple short hairs are formed on the outer surface of the exterior member 16, creating a carpet-like surface. The short hairs are preferably made of chemical fibers such as synthetic fibers (such as polyester), semi-synthetic fibers (such as acetate), and regenerated fibers (such as rayon), or natural fibers such as cotton and linen. As with the uneven structure, the outer diameter of the short-haired outer diameter adjusting structure 20c varies depending on the measurement location, but the average value is preferably 4.0 mm to 7.5 mm, more preferably 5.0 mm to 7.0 mm, and the difference between the maximum and minimum values ​​is preferably 0.05 to 0.15 mm.

[0023] The outer diameter adjusting structures 20a to 20c may be used individually or in combination with one another.

[0024] The aerosol-forming member 10 is housed inside an interior member 11 made of a sheet-like material formed into a cylindrical shape, and includes an induction heating member 13 that generates heat in response to an external alternating magnetic field, and a filler 12 made of a material that is the aerosol generation source. The length (in the longitudinal direction of the cylinder) is preferably set to approximately 10 to 30 mm. Like the exterior member 16, the interior member 11 is preferably made of a thin, flexible material such as paper or sheet-like resin.

[0025] The outer diameter of the aerosol-forming member 10 is a generally constant value along the central axis. This outer diameter 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.

[0026] <About Filling 12> Filler 12 is made of a material formed by mixing dried and ground tobacco or non-tobacco plants with an aerosol former that generates an aerosol, microcrystalline cellulose, flavor additives, preservatives, adhesives, or thickeners, etc., and then forming the mixture into a sheet, for example, and cutting it to a predetermined width and length. Filler 12 may have a variety of shapes, including sheets, strips, pastes, particles (including granules) or powders, porous materials, rods, plates, fibers, small pieces, and mixtures thereof.

[0027] When the filler 12 is configured in a 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. The length of the filler 12 is substantially the same as the longitudinal length of the aerosol-forming member 10, for example, 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 12 is a long side of 1.5 mm, a short side of 0.3 mm, and a length of 12 mm.

[0028] When the filler 12 is in a powder or granular form, it is preferable to appropriately pulverize or classify the composition. The average particle size of the powder or granular filler 12 is preferably, for example, 0.1 to 3.0 mm, and more preferably 0.5 mm or less.

[0029] Next, a description will be given of specific examples of raw materials used as the filler 12. The filler 12 is made of any one or a combination of the following raw materials.

[0030] The filler 12 is made from tobacco plants or non-tobacco plants. Examples of tobacco plants include tobacco leaves, tobacco stems, expanded tobacco, and homogenized tobacco. 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, bark (stem bark, bark, etc.), flowers (petals, stamens, pistils, etc.), trunks, and branches.

[0031] In this specification, "plants" refers to a group of organisms, as opposed to animals, and includes not only 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.

[0032] Filler 12 may be prepared, for example, by mixing dried and crushed non-tobacco plant material with an aerosol former for generating an aerosol, microcrystalline cellulose, flavor additives for adding flavor, preservatives, binders, or thickeners, and then crushing or classifying the mixture into powder or granules, or forming it into a paste. Filler 12 may also be formed into a sheet and then cut into strips or rods of a predetermined width and length. The thickness of the sheet is preferably 0.1 mm to 1.0 mm, and more preferably 0.1 mm to 0.5 mm. Filler 12 may be in any one of the following forms: sheet, strip, granule, powder, paste, plate, or fiber, or a mixture of two or more of these forms.

[0033] When the filler 12 is in a sheet form, it is preferably a long rectangular shape with one side approximately equal to the longitudinal length of the aerosol-forming member 10 and the other side longer than the other side. The thickness of the sheet is preferably in the range of 0.1 mm to 1.0 mm, as described above, and more preferably in the range of 0.1 mm to 0.5 mm. This shape facilitates the crimping and deformation described below. The length of the longitudinal side of the filler 12 is preferably a length that allows it to be accommodated in the cylindrical internal space of the interior member 11 in a crimped or deformed state together with the induction heating member 13, and more preferably a length that is approximately equal to the volume of the space. Furthermore, to facilitate deformation such as crimping and rotation, it is preferable to form lines with a certain depth. The depth of the lines may be the same as the thickness of the sheet (i.e., forming through holes in the sheet) to form slit-shaped lines, or may be less than the thickness of the sheet (i.e., forming blind holes in the sheet) to form trench-shaped lines.

[0034] In addition, tea leaves can be used when non-tobacco plants are used as raw materials. Tea leaves vary not only depending on the plant that produces the tea, but also depending on the processing method, even within the same plant, different tea leaves can be produced. Specific examples include Japanese tea, black tea, and oolong tea.

[0035] As the aerosol former, for example, glycerin, propylene glycol, etc. are preferably used.

[0036] Next, microcrystalline cellulose is obtained, for example, by partially depolymerizing α-cellulose obtained from the pulp of fibrous plants with an acid, and is obtained by removing the soluble portion from the cellulose and, if necessary, crystallizing the insoluble portion.

[0037] The microcrystalline cellulose may be in the form of powder or may be dispersed in a solvent such as water to form a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used to disperse the microcrystalline cellulose in the solvent.

[0038] Furthermore, if necessary, a flavor additive for adding flavor may be used as the filler 12. Examples of flavor additives include mint, cocoa, coffee, black tea extract, and tea extract catechin powder. Preservatives that are used in food are preferred, such as sorbic acid, potassium sorbate, benzoic acid, and sodium benzoate.

[0039] Binders or thickeners include gums such as guar gum, cellulosic binders such as hydroxypropyl cellulose, polysaccharides such as conjugate base salts of organic acids such as starch, and combinations thereof.

[0040] When forming the composition into a paste, fluidity can be imparted by adding an appropriate amount of a thickener, water, etc. to the powdered or granular composition and kneading the mixture.

[0041] Furthermore, when providing adhesiveness to the surface of filler 12, any means capable of providing adhesiveness may be used, but it is sufficient to attach the aforementioned binder to at least a portion of the surface. By providing adhesiveness, when strip- or rod-shaped filler 12 is combined with powder-, granular, or paste-like filler 12, the powder-, granular, or paste-like filler 12 can be stably held on the surface of strip- or rod-shaped filler 12.

[0042] Furthermore, impregnating or applying an antioxidant to the interior or surface of the filler 12 is preferable because it can prevent or inhibit deterioration due to oxidation of the components (especially plants) of the filler 12 and rust of the induction heating member 13. Examples of preferred antioxidants include sodium sulfite, dibutylhydroxytoluene, butylhydroxyanisole, L-ascorbic acid (vitamin C), and vitamin E. Furthermore, the aforementioned catechin is also preferred because it has an antioxidant effect. Catechin is a component unique to green tea leaves, and green tea leaves contain epigallocatechin, epigallocatechin gallate, epicatechin, and epicatechin gallate. In other words, when tea leaves containing catechin (e.g., green tea) are used as components of the filler 12, adding catechin can further enhance the antioxidant effect. For example, in the case of green tea, approximately 80% of its components are thought to be derived from catechins. Therefore, by incorporating catechins in the filling 12 in an amount equivalent to 80% or more of the weight of the green tea leaves contained in the filling 12, it is possible to obtain a further antioxidant effect. Furthermore, of the catechins contained in green tea, epigallocatechin gallate accounts for approximately 60%, epigallocatechin gallate for approximately 20%, epicatechin gallate for approximately 13%, and epicatechin for approximately 7%. Increasing the amount of epigallocatechin gallate, which has particularly high antioxidant properties, is even more effective in improving the antioxidant function. When using a plant that does not contain catechins in the filling 12, it is effective to add catechins, particularly epigallocatechin gallate, to the filling 12. In this case, adding catechins (particularly epigallocatechin gallate) in an amount equivalent to or greater than 80% of the weight of the plant material contained in the filling 12 makes it possible to obtain antioxidant properties equivalent to or better than those obtained when green tea is used.

[0043] <Regarding induction heating member 13> In this patent, the induction heating member 13 is made by processing a thin, flat plate-shaped material. The thickness of this plate is preferably 0.05 to 0.5 mm, and more preferably 0.1 to 0.3 mm. Its length is preferably approximately the same as the longitudinal length of the aerosol-forming member 10, but may differ from the length of the aerosol-forming member 10 to the extent that it does not impede the formation of aerosol. Specifically, it is preferably about ±1 to 3 mm. The induction heating member 13 does not necessarily have to be flat, and can be polygonal, rod-shaped, columnar, cylindrical, particulate, spherical, porous, sheet-shaped, L-shaped, V-shaped, U-shaped, U-shaped, or a variety of other shapes, including combinations thereof.

[0044] The induction heating member 13 is made of a metal material containing a ferromagnetic substance. A ferromagnetic substance is a material that, when subjected to an external magnetic field, becomes strongly magnetized in the same direction as the external magnetic field and is particularly attracted to a magnet. Examples of such a ferromagnetic substance include iron, ferrite iron, ferrite powder, ferrite particles, magnetic stainless steel such as ferritic or martensitic stainless steel (e.g., SUS430 or SUS410), nickel, nickel-iron alloys (e.g., 42 alloy or 36 invar), and cobalt. The relative permeability of a ferromagnetic substance is significantly greater than 1; for example, iron is approximately 5000, nickel is approximately 600, cobalt is approximately 250, and ferritic stainless steel is approximately 1000 to 1800.

[0045] Among magnetic materials, paramagnetic materials are those that, when an external magnetic field is applied, become weakly magnetized in the same direction as the external magnetic field, and lose their magnetism when the external magnetic field is reduced to zero, such as aluminum, platinum, and manganese.The relative permeability of paramagnetic materials is slightly greater than 1, for example, approximately 1.000021 for aluminum, approximately 1.000265 for platinum, and approximately 1.000830 for manganese.

[0046] Diamagnetic materials, among magnetic materials, are materials that become magnetized in the opposite direction to an external magnetic field when it is applied, and lose their magnetism when the external magnetic field is reduced to zero, such as copper, graphite, bismuth, etc. The relative permeability of diamagnetic materials is slightly less than 1, for example, about 0.999990 for copper, about 0.99980 for graphite, and about 0.999834 for bismuth.

[0047] When a ferromagnetic material is placed inside a magnetic field (alternating magnetic field) whose direction and magnitude change over time, not only does it generate Joule heat due to eddy currents that flow due to electromagnetic induction, but it also generates heat due to energy loss (hysteresis loss) that occurs when the direction of magnetization inside the ferromagnetic material changes.Therefore, it can be easily induced heated compared to paramagnetic or diamagnetic materials, and can sufficiently heat the aerosol suction cartridge 1.

[0048] Furthermore, the Curie temperature, which is the temperature at which a ferromagnetic material loses its magnetic order and transitions to a paramagnetic material, is, for example, about 358° C. for nickel. Therefore, even when the aerosol suction cartridge is heated to a high temperature, such as 200° C., the heating temperature does not reach the Curie temperature, and the properties of the ferromagnetic material are maintained, allowing the aerosol suction cartridge 1 to be heated stably.

[0049] The material of the induction heating member 13 may be a ferromagnetic material such as iron, ferrite iron, ferrite powder, ferrite particles, ferritic stainless steel, ferromagnetic steel, stainless steel, nickel, cobalt, or a metal material that is a combination of these. For example, a combination of ferritic stainless steel and nickel can be used, and more preferably, an alloy that is a combination of iron, chromium, and aluminum (iron-chromium-aluminum alloy).

[0050] Here, we will explain the relationship between temperature and magnetism of iron and chromium. The Curie temperature of iron is approximately 770°C, and the Neel temperature of chromium, which is the temperature at which it changes from an antiferromagnetic material to a paramagnetic material, is approximately 35°C.

[0051] The induction heating member 13 may also be made of a metal material containing a ferromagnetic material as a main component, such as a ferromagnetic alloy, which is an alloy containing preferably 60% or more, and more preferably 80% or more, of a ferromagnetic material. Examples include nickel alloys and nickel-iron alloys. Even in this case, the aerosol suction cartridge 1 can be sufficiently heated by inductively heating the ferromagnetic material. Instead of the ferromagnetic material, a metal material containing a paramagnetic material and a diamagnetic material may be used. In this case, induction heating is still possible. However, from the viewpoint of shortening the heating time and reducing power consumption, it is preferable to use a metal material containing a ferromagnetic material.

[0052] The induction heating member 13 may also be partially or entirely crimped from a sheet-like material. For example, when viewed in the longitudinal direction of the aerosol-forming member (i.e., when viewed from the front of the cylinder), it may be crimped into a spiral or vortex shape. It may also be crimped into a folded shape with alternating overlapping portions. Furthermore, it may be an irregular shape that combines spirals, folded shapes, and other shapes.

[0053] Also, when viewed from a similar perspective, the filler 12 may be partially or entirely in the form of a thin film (sheet-like) material that is crimped, and the induction heating member 13 may be partially or entirely in contact with and follow the filler 12 to form a crimped shape. Therefore, like the induction heating member 13, the filler 12 may also be in a convoluted or folded shape, or an irregular shape that is a combination of convoluted, folded, and other shapes. In such a configuration, the sheet-like induction heating member 13 follows the filler 12 while contacting it, increasing the contact area between them and improving heating efficiency and aerosol generation.

[0054] Here, in order to prevent deterioration of the heat generating function due to rust, it is preferable that an anti-rust layer is formed on part or all of the surface of the induction heating member 13, and it is more preferable that an anti-rust layer is formed on the entire surface.

[0055] Here, possible types of anti-rust layers include, for example, a brazing material film, a phosphate film, and an iron oxide film. These are preferable materials for the anti-rust layer because they do not generate substances harmful to the human body even when the induction heating member 13 reaches a high temperature. Furthermore, the material is not limited to one of these types, and two or more types may be combined.

[0056] In the case of a wax film, possible materials include beeswax, wax wax, sugarcane wax, spermaceti, and wool wax, and this film is formed on the surface of the induction heating member 13. The application method can be, for example, by applying the molten wax with a regular brush (brush coating method), by immersing the induction heating member 13 in the wax (dip coating method), or by spraying (spraying method). There are no particular restrictions on the film thickness, but if it is too thin, sufficient rust prevention effect cannot be obtained, while if it is too thick, it may affect the heating of the filler and inhibit the generation of aerosols, so it is preferable to set the thickness appropriately. Specifically, a thickness of 0.005 mm to 1 mm is preferable, and a thickness of 0.01 to 0.5 mm is even more preferable.

[0057] A phosphate coating is a coating chemically formed on the surface of a metal by chemical treatment (phosphate treatment) using a solution of phosphate such as iron phosphate, zinc phosphate, calcium phosphate, or manganese phosphate, and has the function of preventing metal corrosion. Here, the standard phosphate treatment process preferably includes the following steps for the treated object: (1) alkaline degreasing, (2) water washing, (3) phosphate conversion treatment, (4) water washing, and (5) drying. Phosphate conversion treatment is generally performed by immersing the metal to be treated in a phosphate solution, but other methods, such as spraying the phosphate solution, may also be used. The thickness of the phosphate coating varies depending on the treatment time, but is preferably 1 μm to 20 μm.

[0058] By forming a phosphate film on a part or the whole of the surface of the induction heating member 13 by phosphate treatment, it is possible to improve the rust prevention ability of the induction heating member 13.

[0059] It is also possible to prevent or inhibit the formation of rust by artificially forming an iron oxide film on the metal surface. Here, triiron tetroxide (Fe3O4), commonly known as black rust, is preferred as the iron oxide film because it forms a stable passive film. A standard process for forming a triiron tetroxide film preferably includes the following steps: (1) alkaline degreasing of the workpiece, (2) water or hot water washing, (3) alkaline aqueous solution (preferably caustic soda) at 140-150°C, (4) water or hot water washing, and (5) drying. The oxide film generally has a thickness of approximately 1-2 μm.

[0060] The support member 15 is disposed between the aerosol-forming member 10 and the mouthpiece 14. It prevents the aerosol-forming member 10 from moving toward the support member 15 and the exterior member 16 from bending, while allowing the airflow containing the aerosol generated by the aerosol-forming member 10 to flow toward the mouthpiece 14. The support member 15 is formed, for example, in a cylindrical shape and is disposed between the aerosol-forming member 10 and the mouthpiece 14 so that its longitudinal axis is aligned with the central axis of the aerosol suction cartridge 1. The support member 15 is formed, for example, with a diameter of 4.0 mm to 7.5 mm and a length along the central axis of 50 mm or less. The support member 15 may have dimensions different from those described above depending on its function and configuration. In this embodiment, a support member main body formed of a resin material has vent holes formed therein to serve as an air flow path. Examples of materials for the support member 15 include plastics such as polypropylene, rubbers such as polylactic acid and silicone, metals, and wood. Paper may also be used.

[0061] In embodiment 1, the support member 15 has a hollow tubular shape overall, with through holes in the longitudinal direction of the cylinder (from the upstream side to the downstream side of the aerosol), and is arranged downstream of the aerosol-forming member, and also serves as a ventilation section for circulating the aerosol.

[0062] The mouthpiece 14 is formed in a cylindrical shape, and its height is set to 10 to 50 mm. The mouthpiece 14 is formed from a material such as paper. Alternatively, the mouthpiece 14 may be formed 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. Alternatively, the mouthpiece 14 may be formed from a porous material containing silicone. The mouthpiece 14 is a white filter that functions to filter out some of the fine particles in the water vapor and aerosol generated by the aerosol-forming member 1. Note that if the filler 13 is made from a material other than tobacco plants, the mouthpiece 14 is not necessarily required.

[0063] Next, the sealing member 17 is formed in a cylindrical shape, with a diameter of 4.0 mm to 7.5 mm and a height of 3.0 to 7.0 mm, for example. Like the mouthpiece 14, the sealing member 17 may be formed into a cylindrical shape by rolling up a sheet-like material made of paper, or may be formed from a resin such as silicone or plastic, or may use cellulose acetate. The sealing member 17 has the function of allowing air to pass from the outside of the cartridge toward the aerosol-forming member 10. Furthermore, the sealing member 17 can absorb any residual liquid that remains in the aerosol-forming member 10 and liquefies, among the water vapor and aerosol generated in the aerosol-forming member 10. By making the sealing member 17 a different color (e.g., black) from the mouthpiece 14, it is possible to easily distinguish between the upstream and downstream sides of the aerosol inhalation cartridge 1. Furthermore, to improve breathability, a through-hole serving as a passageway for the aerosol may be provided.

[0064] According to the invention of embodiment 1, the outer diameter adjustment member 19 is in close contact with the outer surface of the aerosol suction cartridge, i.e., the outer member 16 or the mouthpiece protection member 18, thereby partially increasing the outer diameter of the aerosol suction cartridge 1, so that it fits well into the insertion portion D1 of the induction heating device D and prevents it from coming loose during use.

[0065] In addition, the outer diameter adjustment structure 20 partially increases the outer diameter of the aerosol suction cartridge 1 and increases the friction between the outer surface and the insertion part D1, so that it fits well into the insertion part D1 of the induction heating device D and prevents it from coming loose during use.

[0066] Embodiment 2 5 and 6 are a schematic side cross-sectional view and a schematic front cross-sectional view of an aerosol suction cartridge 2 according to a second embodiment of the invention, and Fig. 7 is a schematic perspective view of an outer diameter adjusting member 25. Here, illustrations and descriptions of the same configuration as in the first embodiment will be omitted as appropriate.

[0067] The aerosol suction cartridge 2 comprises a cylindrical exterior member 16 and an outer diameter adjusting member 25 housed within the tube for expanding the outer diameter of the exterior member 16. The size and shape of the exterior member 16 are the same as in the first embodiment, but the material is preferably a deformable material such as paper (including synthetic paper), rubber, or plastic.

[0068] The outer diameter adjusting member 25 is made of an elastic material, such as plastics such as polypropylene, rubbers such as polylactic acid and silicone, metals, and wood.

[0069] 6(a) corresponds to the support member 15 of the first embodiment and is formed in a cylindrical shape, but has one or more protrusions 25a-1 on its outer periphery (i.e., outer surface) along the height direction in a cross section perpendicular to its height direction (front cross section). In this example, two protrusions 25a-1 are formed on a line passing through the center of the circle forming the cross section.

[0070] The length of a straight line starting from the apex of the protrusion 25a-1, passing through the center of the diameter of the outer periphery of the outer casing 16, and ending at a point on the outer periphery (here, the apex of the opposing protrusion 25a-1) is set to be greater than the inner diameter of the outer casing 16 when the outer diameter adjustment member 25a is not housed. In other words, when the outer diameter adjustment member 25a is housed, the protrusion 25a-1 pushes the outer casing 16 apart from the inside. If the outer diameter adjustment member 25a is made of an elastic material and the outer casing 16 is made of a deformable material, the force with which the protrusion 25a-1 pushes the outer casing 16 apart can be appropriately adjusted. This allows the outer diameter of the aerosol suction cartridge 2 to be partially enlarged without damaging the outer casing 16 or the outer diameter adjustment member 25a. The number of protrusions 25a-1 is not limited to two, and may be one, three, or more. If two or more protrusions are installed, they are preferably arranged regularly in a front cross-sectional view. For example, in FIG. 7(a), two protrusions 25a-1 are arranged at 180° intervals, but three may be arranged at 120° intervals or four may be arranged at 90° intervals.

[0071] On the other hand, as in the outer diameter adjustment member 25b shown in Figures 6(b) and 7(b), a configuration in which protrusions 25b-1 are formed along the height direction on the outer periphery (outer surface or ridge line) of the rectangular column shape is also possible. In this case, a space can be formed between the outer surface of the outer diameter adjustment member 25b and the inner surface of the exterior member 16, so ventilation holes like those in the support member 15 are not necessarily required. In Figure 6(b), two protrusions 25b-1 are formed on corners located on one diagonal line of the quadrangle that forms the cross section, but the number of protrusions can be freely set between one and four.

[0072] Furthermore, as shown in Figures 7(a) and (b), the protrusions 25a-1 and 25b-1 are formed over the entire height of the cylinder or rectangular pillar, but this is not limited to this. For example, as shown in Figure 7(c) as a modified example of Figure 7(a), one or more protrusions 25c-1 (six in total in the figure) may be formed over a portion of the length of the cylinder in the height direction.

[0073] According to the invention described in embodiment 2, the protrusions 25a-1, 25b-1 of the outer diameter adjustment member 25 push the outer casing member 16 from the inside, thereby partially increasing the outer diameter of the aerosol suction cartridge 2, so that it fits well into the insertion portion D1 of the induction heating device D and prevents it from coming loose during use.

[0074] Embodiment 3 Fig. 8 is a schematic perspective view of an aerosol suction cartridge 3 according to a third embodiment of the invention, and Fig. 9 is a schematic plan view of a mouthpiece protection member 18. Here, illustrations and descriptions of the same configurations as those in the first and second embodiments will be omitted as appropriate.

[0075] The aerosol suction cartridge 3 has a cylindrical exterior member 16, a cylindrical mouthpiece 14 connected to one end of the exterior member, and a sheet-shaped mouthpiece protection member 18 wrapped around part of the outer periphery of the exterior member 16 and all or part of the outer periphery of the mouthpiece 16. The exterior member 16 and the mouthpiece 14 are the same as those in the first and second embodiments.

[0076] Here, mouthpiece protection member 18 is a sheet made of paper or resin, as in the first and second embodiments, but differs in that it has outer diameter adjustment section 18-1 formed by expanding the sheet toward the upstream side of the aerosol of exterior member 16. Here, the thickness of mouthpiece protection member 18 is preferably 0.01 to 0.15 mm, and the length of outer diameter adjustment section 18-1 (i.e., the length by which the sheet expands) is preferably 5 to 20 mm along the height direction of exterior member 16 toward the upstream side of the aerosol.

[0077] Furthermore, it is preferable that the outer diameter adjustment portion 18-1 be formed discontinuously along the circumferential direction perpendicular to the height direction of the exterior member 16. That is, in the plan view of FIG. 9, the outer diameter adjustment portions 18a-1 and 18b-1 are arranged at a predetermined interval. This arrangement pattern is preferably regular. Here, the outer diameter adjustment portion 18a-1 in FIG. 9(a) is semi-wave-shaped, but it may also be square-wave-shaped like 18b-1 in FIG. 9(b). The outer diameter adjustment portion 18-1 may be one or more, and if there are more than one, some or all of them may have different shapes or sizes. In this case, it is preferable that the insertion side (seal member 17 side) of the aerosol suction cartridge 3 be tapered, narrower than the mouthpiece 14 side, as in the case of the outer diameter adjustment portion 18a-1, because this facilitates insertion into the insertion opening D1.

[0078] According to the invention described in embodiment 3, the outer diameter adjustment portion 18-1 formed on the upstream side of the aerosol partially increases the outer diameter of the aerosol suction cartridge 3, so that it fits well into the insertion portion D1 of the induction heating device D and can prevent it from coming loose during use.

[0079] Although the first to third embodiments of the present invention have been described above, the scope of the present invention is not limited to the above-described embodiments and extends to other embodiments that can be regarded as equivalent thereto. It is also possible to use different embodiments in combination. In the following description, when referring to an aerosol suction cartridge 1, etc., this is used to collectively refer to the aerosol suction cartridges 1 to 3. The same applies to other configurations.

[0080] For example, in embodiment 1 etc., the interior member 11 is wrapped around the filler 12 in a single layer, but by wrapping it spirally as shown in Figure 10(a) or wrapping it multiple times, the outer diameter of the aerosol-forming member 10 can be increased partially or entirely, and by expanding the exterior member 16 from the inside, it is possible to increase the outer diameter of the aerosol suction cartridge 1 etc. partially or entirely.

[0081] The packing 12 of the present invention may be used as an aerosol suction cartridge for resistance heating without housing the induction heating element 13.

[0082] Furthermore, the number of induction heating members 13 etc. included in the aerosol-forming member 10 etc. is not limited to one, and a plurality of induction heating members 13 etc. may be included, which makes it possible to improve the aerosol generation efficiency.

[0083] The filler 12 may also be in various forms, such as a sheet, strip, paste, granules or powder, porous, rod, plate, fiber, small pieces, or a mixture of these.

[0084] In addition, the support member 15 and the seal member 17 do not necessarily need to be installed if the aerosol-forming member 10 does not move. For example, the mouthpiece 14 or the like may be placed adjacent to the aerosol-forming member 10, or the location where the support member 15 was located may be left as a space (i.e., the entire space between the aerosol-forming member 10 and the mouthpiece 14 or the like may be hollow). This reduces the number of parts, which is effective in reducing costs. Providing a space is particularly effective in improving breathability. Furthermore, the elimination of the seal member 17 and the support member 15 allows the aerosol-forming member 10 to be longer, thereby improving the user's comfort.

[0085] Furthermore, in the first and second embodiments, the exterior member 16 and the mouthpiece protection member 18, etc., are not necessarily separate components, and one may serve as the other. For example, the exterior member 16 may be extended to house the mouthpiece 14 therein, thereby forming the aerosol suction cartridge 1, etc., or the mouthpiece protection member 18, etc. may integrally encompass the sealing member 17, the aerosol-forming member 10, the support member 15, and the mouthpiece 14, etc. This allows for simplification of the manufacturing process and reduction of manufacturing costs.

[0086] In addition to the tea leaves mentioned in the embodiment, all commonly used tea leaves can be used as the raw material for the filling 12. Also, used tea leaves can be used for these tea leaves. Using used tea leaves allows for the effective reuse of expensive tea leaves.

[0087] Extracts of the above-mentioned non-tobacco plants, so-called extracts and processed products, can also be used. The extracts may be in the form of liquid, starch syrup, powder, granules, solution, etc.

[0088] In addition to the aerosol formers mentioned in the embodiments, other aerosol formers that can be used as raw materials for the filler 12 include 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.

[0089] Furthermore, menthol and a water-insoluble crosslinked polymer (preferably polyvinylpolypyrrolidone) may be contained as flavor additives. By combining menthol with a water-insoluble crosslinked polymer, sublimation of menthol can be effectively suppressed, and the menthol flavor can be maintained for a long period of time. Here, menthol is not limited to that obtained from natural products, but may also be a synthetic product. Peppermint, mint, peppermint oil, and other menthol-containing substances may also be used.

[0090] In addition to those mentioned in the embodiments, binders or thickeners used as raw materials for the filling 12 include gums such as xanthan gum, gum arabic, and locust bean gum; cellulose binders such as carboxymethyl cellulose, hydroxyethyl cellulose, methyl cellulose, and ethyl cellulose; polysaccharides such as organic acids such as alginic acid, sodium alginate, sodium carboxymethyl cellulose, caranagin, agar, and conjugate base salts of organic acids such as pectin; and combinations thereof.

[0091] When using raw materials that do not contain nicotine, such as non-tobacco plants, substances that provide a similar sensation to nicotine, i.e., a kick, may be added. Preferred examples include plants of the Piperaceae family (such as pepper, long pepper, pseudo-piper, and capsicum), black pepper, white pepper, piperine, lobeline, chavicin, capsaicin, dihydrocapsaicin, glucosinolate, and allyl isothiocyanate.
