[0007] Patent Document 3: Japanese Patent Application Publication No. 2021-502800. Summary of the Invention

[0008] Technical problem to be solved by the invention

[0009] When a user of the aerosol-generating device (hereinafter referred to as the user) removes the aerosol-generating article from the storage section after heating it, sometimes a portion of the aerosol-generating article adheres to the inner surface of the heating section and the storage section, making it impossible to remove. Therefore, Patent Document 3 proposes an aerosol-generating device comprising a rotating section capable of relative circumferential movement between an aerosol-forming substrate and a heating element. However, the aerosol-generating device in Patent Document 3 suffers from problems such as increased complexity or size.

[0010] One of the objectives of this invention is to provide an aerosol generation system that inhibits the increasing complexity or size of aerosol generation devices and prevents the contents of the aerosol-generated article from remaining in the storage compartment when the article is removed from the storage compartment.

[0011] Technical solutions to technical problems

[0012] According to a first aspect, an aerosol-generating system is provided. The aerosol-generating system includes an aerosol-generating device, an aerosol-generating article that generates aerosol by heating, and a heating unit. The aerosol-generating device includes a storage unit that stores the aerosol-generating article, and a power supply unit that supplies power to the heating unit, so that the heating unit heats the aerosol-generating article stored in the storage unit. The storage unit includes a first-shaped portion having a protruding first shape formed at a bottom of the storage unit. The aerosol-generating article includes an end portion that is inserted into the storage unit, the end portion being configured to include a second-shaped portion having a second shape corresponding to the first shape when the aerosol-generating article is stored in the storage unit. At least a portion of a surface of the second-shaped portion is inclined relative to the longitudinal direction of the aerosol-generating article.

[0013] According to the first aspect, the complexity or size of the aerosol-generating device can be suppressed. Furthermore, the second shape corresponding to the protruding first shape can prevent the contents of the aerosol-generating article from remaining in the storage portion when the aerosol-generating article is removed from the storage portion. This reduces the need for maintenance such as cleaning. Furthermore, by suppressing adhesion of the aerosol-generating article to the heating portion, a decrease in heating efficiency can be suppressed.

[0014] The purpose of the second method is that, in the first method, the second shape portion retains the contents of the aerosol-generating article in a manner that does not remain in the storage portion when the aerosol-generating article is removed from the storage portion.

[0015] According to the second method, by retaining the second shape portion, when the aerosol-generating article is removed from the storage portion, it is possible to more reliably suppress the contents of the aerosol-generating article from remaining in the storage portion.

[0016] The essence of the third approach is that, in the first or second approach, the surface of the second shaped portion is formed by packaging material for packaging the aerosol-generating article.

[0017] According to the third approach, an aerosol generation system can be provided that achieves the effects of the above-mentioned approach at a low cost and with high efficiency.

[0018] The fourth approach is that, in the third approach, the packaging material has a weight of 20 gsm to 200 gsm in the portion constituting the second shape portion.

[0019] According to the fourth method, when the aerosol-generating article is removed from the storage section, the contents of the aerosol-generating article can be firmly retained by the packaging material to prevent the contents from remaining in the storage section, and adverse effects caused by excessive packaging material, such as difficulty in forming the second shape section, can be suppressed.

[0020] The fifth aspect is that, in the third or fourth aspect, the second shaped portion has a folded-in portion toward the inside of the end of the packaging material.

[0021] According to the fifth aspect, when the aerosol-generating article is taken out from the storage unit, the contents of the aerosol-generating article can be more reliably prevented from remaining in the storage unit. Furthermore, by folding the packaging material, an aerosol-generating article having such an effect can be easily formed.

[0022] The gist of the sixth aspect is that, in any one of the first to fifth aspects, at least a portion of the surface of the second-shaped portion is inclined relative to the direction in which the aerosol-generating article is inserted into the storage portion so that its tangent plane intersects with the central axis of the aerosol-generating article on the end face side closer to the end portion than the at least a portion.

[0023] According to the sixth aspect, by holding the surface inclined with respect to the insertion direction, it is possible to more reliably prevent the contents of the aerosol-generating article from remaining in the storage portion when the aerosol-generating article is taken out from the storage portion.

[0024] The seventh aspect is that, in any one of the first to sixth aspects, the width of the second shape in a direction perpendicular to the longitudinal direction of the aerosol-generating article increases toward the end surface of the end portion of the aerosol-generating article.

[0025] According to the seventh method, for a wider range of contents in aerosol-generating articles, when the aerosol-generating articles are removed from the storage section, it is possible to suppress the contents from remaining in the storage section.

[0026] An eighth aspect, in any one of the first to seventh aspects, is gist of the second shape portion being arranged on both sides of the end portion along a direction perpendicular to the longitudinal direction of the aerosol-generating article.

[0027] According to the eighth aspect, when the aerosol-generating article is taken out from the storage portion, the second-shaped portion holds the contents on both sides of the end portion of the aerosol-generating article, and thus it is possible to more reliably prevent the contents from remaining in the storage portion.

[0028] The essence of the ninth method is that, in any of the first to eighth methods, the first shape has an arched shape.

[0029] As described later, in the aerosol generating article, the side with the end initially inserted into the aerosol generating device is designated as the upstream side, and the opposite side is designated as the downstream side. According to the ninth method, by applying force inward and downstream to the side of the aerosol generating article through the arched inclined surface, when the aerosol generating article is removed from the storage section, the contents of the aerosol generating article can be firmly retained by the force-applied portion, thus preventing contents from remaining in the storage section.

[0030] The gist of a tenth aspect is that, in any one of the first to ninth aspects, the first shape has a blade shape.

[0031] When the wider surface comes into contact with the end of the aerosol generating article, the contents of the aerosol generating article move in a direction intersecting the pressing direction, and the end of the aerosol generating article expands. According to the tenth method, when force is applied to the end of the aerosol generating article through the leaf-shaped first part, the end is less likely to expand compared to the case where force is applied through the wider surface. Therefore, when the aerosol generating article is removed from the storage part, the contents are less likely to remain in the storage part.

[0032] The essence of the eleventh aspect is that, in any of the first to tenth aspects, the storage portion includes: a bottom wall that intersects with the central axis of the storage portion, which is its central axis; and a side wall that extends along the central axis of the storage portion, wherein the first shaped portion is disposed in contact with at least one of the bottom wall and the side wall.

[0033] According to the eleventh method, the user does not need to perform complicated operations. When storing the aerosol-generated item in the storage section, the second shape section can be formed by the first shape section formed on the bottom wall or side wall.

[0034] The summary of the twelfth aspect is that, in the eleventh aspect, the surface of the first shape portion is inclined with respect to the central axis of the storage portion.

[0035] According to the twelfth method, force can be applied to the end of the aerosol generating article towards the inside of the aerosol generating article by means of an inclined surface, so that when the aerosol generating article is removed from the storage section, the contents are more reliably less likely to remain in the storage section.

[0036] The essence of the thirteenth aspect is that, in the twelfth aspect, in a longitudinal section including the central axis of the storage portion, the angle between the surface of the first shaped portion and the central axis of the storage portion is 30° or more and 60° or less.

[0037] According to the thirteenth aspect, when the aerosol-generating article is inserted into the storage portion, the folded portion can be easily formed, and the aerosol-generating article can be urged inward.

[0038] The summary of the fourteenth aspect is that, in any of the eleventh to thirteenth aspects, the first shape has a sharp shape that becomes thinner toward the housing portion central axis in a radial direction relative to the housing portion central axis.

[0039] According to the fourteenth aspect, the first shape portion can bias the aerosol-generating article radially toward the central axis of the storage portion without expanding the end of the aerosol-generating article. When the aerosol-generating article is removed from the storage portion, the contents are less likely to remain in the storage portion.

[0040] The gist of the fifteenth aspect is that, in any one of the eleventh to fourteenth aspects, the width of the first shape in a direction perpendicular to the central axis of the storage portion gradually decreases or gradually increases along the central axis of the storage portion.

[0041] According to the fifteenth method, by not drastically changing the first shape, it is possible to suppress the breakage of the aerosol-generating article that comes into contact with the first shape portion.

[0042] The gist of a sixteenth aspect is that, in any one of the eleventh to fifteenth aspects, a plurality of first shape portions are provided in the storage portion at different circumferential positions relative to a central axis of the storage portion.

[0043] According to the sixteenth aspect, when the aerosol-generating article is stored in the storage section, the plurality of second-shaped portions corresponding to the plurality of first-shaped portions are present in the aerosol-generating article. Therefore, when the aerosol-generating article is taken out of the storage section, the contents are less likely to remain in the storage section.

[0044] The gist of a seventeenth aspect is that, in any one of the first to sixteenth aspects, the storage section includes the heating section, or a metal body stored in the storage section together with the aerosol-generating article constitutes a heat generating element of the heating section.

[0045] According to the seventeenth method, the heating element can be designed flexibly.

[0046] The essence of the eighteenth method is that, in the seventeenth method, the storage part includes the heating part, and the heating part includes a plate-shaped heater.

[0047] According to the eighteenth aspect, the heating unit can be easily inserted into the aerosol-generating article. Furthermore, when the first shape portion is formed along the width direction of the plate-shaped heater, the end portion of the aerosol-generating article can be easily folded in.

[0048] The essence of the nineteenth aspect is that, in the eighteenth aspect, the first shaped portion is arranged at the bottom of the receiving portion in a direction extending along the plate-shaped heater.

[0049] According to the nineteenth aspect, since the distance between the first-shaped portion and the heating portion can be shortened, the end of the aerosol-generating article stored in the storage portion can be urged closer to the heating portion, thereby more reliably preventing the contents of the aerosol-generating article from remaining in the storage portion when the aerosol-generating article is removed from the storage portion. Furthermore, a more compact aerosol-generating device can be realized, for example, by thinning the thickness of the plate-shaped heater.

[0050] The essence of the twentieth embodiment is that, in any of the seventeenth to nineteenth embodiments, the storage section includes the heating section, and the heating section includes a PTC heater.

[0051] According to the twentieth method, by effectively utilizing the characteristics of PTC, the temperature of the heating element can be maintained below a certain temperature without the need for a control device that stops heating when the specified temperature is reached.

[0052] The essence of the twenty-first method is that, in any of the seventeenth to twentieth methods, the heating unit is configured to heat the aerosol generating article from the inside when the aerosol generating article is housed in the aerosol generating device.

[0053] According to method 21, it is possible to efficiently heat aerosols to generate items.

[0054] The essence of the twenty-second aspect is that, in any of the seventeenth to twenty-first aspects, the side wall of the receiving part is further provided with a force-applying part, which applies force to the aerosol generating article toward the heating part when the aerosol generating article is received in the aerosol generating device.

[0055] According to the twenty-second method, by applying force to the force-applying part, the aerosol-generating article can be made to adhere tightly to the heating part, thereby improving heat transfer efficiency and preventing the aerosol-generating article from falling off.

[0056] The gist of the twenty-third embodiment is that, in the twenty-second embodiment, the storage portion includes the heating portion, the heating portion includes a plate-shaped heater, the plate-shaped heater includes a first main surface perpendicular to the thickness direction and a second main surface formed on the back side of the first main surface, and the force-applying portion is arranged opposite to at least one of the first main surface and the second main surface of the plate-shaped heater on the side wall of the storage portion.

[0057] According to the twenty-third method, the contents of the aerosol-generating article move in a direction that intersects with the direction of pressing the first shape portion, and the expansion of the end of the aerosol-generating article can be suppressed by the force-applying portion. As a result, when the aerosol-generating article is removed from the storage portion, the contents are less likely to remain in the storage portion.

[0058] The essence of the twenty-fourth aspect is that, in any of the first to twenty-third aspects, the end of the aerosol generating article does not have the second shape portion, and the end and the first shape portion are configured such that, when the aerosol generating article is inserted into the receiving part, the end is pressed by the first shape portion to form the second shape portion.

[0059] According to the twenty-fourth method, it is not necessary to pre-process the second shape part of the aerosol generating article, and when the aerosol generating article is taken out from the storage part, it is possible to suppress the contents of the aerosol generating article from remaining in the storage part.

[0060] The essence of the twenty-fifth aspect is that, in any of the first to twenty-third aspects, the end of the aerosol generating article has the second shaped portion.

[0061] According to the twenty-fifth method, since the second shape portion is pre-formed, when the aerosol-generating article is removed from the storage portion, the contents of the aerosol-generating article can be more reliably suppressed from remaining in the storage portion.

[0062] The essence of the twenty-sixth aspect is that, in the twenty-fifth aspect, at least one of the aerosol generating article and the aerosol generating apparatus has a mark for inserting the aerosol generating article in such a manner that the first shaped portion and the second shaped portion are opposite each other.

[0063] According to the twenty-sixth method, adverse effects such as reduced heating efficiency caused by the first and second shaped portions being arranged in undesirable relative positions can be suppressed.

[0064] The essence of the twenty-seventh aspect is that, in any of the first to twenty-sixth aspects, the first shape includes a convex portion and the second shape includes a concave portion.

[0065] According to the twenty-seventh method, the end of the aerosol generating article can be easily deformed by the contact of the protrusion, and the contents can be suppressed from remaining in the storage section when the aerosol generating article is removed from the storage section by the concave part obtained by the deformation.

[0066] The essence of the twenty-eighth method is that, in any of the first to twenty-seventh methods, the aerosol generating device is a fragrance inhaler that generates a fragrant aerosol, and the aerosol generating article is a tobacco stick.

[0067] According to the twenty-eighth method, when the tobacco stick is removed from the storage section of the flavor extractor, the contents of the tobacco stick can be prevented from remaining in the storage section. This reduces the need for cleaning and maintenance of the flavor extractor. Furthermore, by preventing the adhesion of aerosol-generating substances to the heating unit, the deterioration of heating efficiency during tobacco smoking can be prevented.

[0091] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In the drawings described below, the same or equivalent constituent elements are labeled with the same reference numerals and repeated descriptions are omitted. It should be noted that in the following embodiments, a tobacco stick is used as an example of an aerosol generating article, but any aerosol generating article that generates aerosol by heating is acceptable, and the aerosol generating article is not limited to cigarettes.

[0092] First embodiment

[0093] Figure 1 This is a cross-sectional view showing the main parts of the aerosol generation system 10 of the first embodiment of the present invention in the width direction of the heating section 120. Figure 2 This is a cross-sectional view showing the main parts of the aerosol generating apparatus 100 constituting the aerosol generating system 10 in the width direction of the heating section 120. Figure 3 This is a cross-sectional view showing the main part of the aerosol generating apparatus 100 in the thickness direction of the heating section 120. Figure 4 yes Figure 3 A cross-sectional view (AA). The aerosol generation system 10 includes an aerosol generation device 100 and an aerosol generation article 200. The aerosol generation device 100 functions as a fragrance extractor that generates a fragrant aerosol by heating the aerosol generation article 200, which is a consumable material containing a fragrance generation substrate, without combustion. Figure 1 The text indicates the state in which the aerosol-generating article 200 is contained within the aerosol-generating device 100. Typically, the user is provided with the aerosol-generating device 100 and the aerosol-generating article 200 not contained within the aerosol-generating device 100. The user then uses the aerosol-generating device 100 to contain the aerosol-generating article 200 and to extract it.

[0094] Hereinafter, the direction perpendicular to the surface extending from the plate-shaped heating section 120 will be referred to as the thickness direction, and the direction perpendicular to both the thickness direction and the length direction of the heating section 120 will be referred to as the width direction. Unless otherwise specified, the X-axis will be taken parallel to the width direction, the Y-axis parallel to the thickness direction, and the Z-axis parallel to the length direction of the heating section 120 (refer to coordinate system CS).

[0095] The aerosol generating apparatus 100 includes a frame 110 and a heating unit 120. The frame 110 has an opening 115 at one end, which functions as a storage section 1A for receiving at least a portion of an aerosol generating article 200 inserted into the frame 110 via the opening 115. The frame 110 includes a side wall 111 and a bottom wall 112. Hereinafter, the bottom wall 112 and the portion of the side wall 111 located opposite the upstream end 250 of the aerosol generating article 200 received in the storage section 1A will be appropriately referred to as the bottom 1B of the storage section 1A. The central axis of the storage section 1A formed by the frame 110 is referred to as the first central axis AX1. The first central axis AX1 extends along the length direction of the frame 110. The side wall 111 extends along the first central axis AX1, and in the illustrated example, the side wall 111 is cylindrical about the first central axis AX1. The bottom wall 112 extends in a direction intersecting the first central axis AX1, and in the illustrated example, it is configured approximately perpendicular to the first central axis AX1. Hereinafter, radial or circumferential refers to the circumferential and radial directions in a rotational coordinate system with the first central axis AX1 as the axis. When the aerosol generating article 200 is housed in the frame 110, the first central axis AX1 overlaps with the second central axis AX2, which serves as the central axis of the aerosol generating article 200. It should be noted that in this embodiment, the case where the outer wall of the frame 110 and the side wall of the housing part 1A are integrated is described as an example, but the housing part 1A with side walls and a bottom wall can also be provided at any position inside the frame 110.

[0096] The frame 110 is made of, for example, a resin, particularly PC (Polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene), PEEK (Poly Ether Ether Ketone), or a polymer alloy containing multiple polymers. Alternatively, the frame 110 can be formed of a metal such as aluminum. In the illustrated example, the frame 110 is configured such that the cross-sectional area of ​​the cross section perpendicular to the longitudinal direction of the frame 110 is smallest near the opening 115, but the present invention is not limited thereto.

[0097] Furthermore, the frame 110 includes a shaping guide (guide portion) 20, a pressing flange 30, and first shape portions 50A and 50B. The shaping guide 20 forms an opening 115, so that the cross-sectional shape of the aerosol generating article 200 inserted into the frame 110 is deformed to correspond to the shape of the heating portion 120. The pressing flange 30 is provided on the inner peripheral surface of the side wall 111 of the frame 110, and functions as a force applying portion that applies force to the aerosol generating article 200 inserted into the frame 110 toward the heating portion 120, thereby deforming the aerosol generating article 200. As long as such force can be applied, the shape of the force applying portion is not limited to the shape shown in the figure. In the present embodiment, the first shape portions 50A and 50B form the second shape portion 3000 ( Figure 7 ), the second shaped portion 3000 prevents the contents of the aerosol-generating article 200 from remaining in the storage portion 1A when the aerosol-generating article 200 is removed from the storage portion 1A. This will be described in detail later. It should be noted that the shaping guide 20 and the holding flange 30 do not need to be provided as long as the aerosol-generating article 200 can be secured to the heating portion 120 with the desired accuracy.

[0098] Furthermore, an air intake hole (not shown) is provided on the bottom wall 112 of the housing 110 on the side opposite the opening 115. By supplying air through this air intake hole to the aerosol-generating article 200 housed in the housing 110, the aerosol generating device 100 constitutes an underflow-type flavor inhaler. Providing the air intake hole on the side opposite the opening 115 of the housing 110 simplifies the structure of the housing 110 near the opening 115.

[0099] The heating element 120 heats the aerosol generating article 200. In this embodiment, the heating element 120 is inserted into the aerosol generating article 200 housed in the frame 110, and heats the aerosol generating article 200 from the inside. This allows for efficient heating of the aerosol generating article 200. The heating element 120 is preferably a plate-shaped heater. The plate-shaped heater facilitates the insertion of the heating element 120 into the aerosol generating article 200. Furthermore, as described later, by forming the first shape portions 50A and 50B along the width direction of the plate-shaped heater, the folding in of the upstream end 250 of the aerosol generating article 200 and the formation of the second shape portion 3000 are easily achieved.

[0100] The heating element 120 includes a resistive heating element (not shown) located inside the frame 110, and can be configured to generate heat by applying a voltage to the resistive heating element. The heating element 120 is preferably a PTC (Positive Temperature Coefficient) heater. From the viewpoint of improving heating efficiency, the heating element 120 is more preferably a plate-shaped PTC heater. Furthermore, the heating element 120 deforms the shape of the aerosol generating article 200 inserted into the frame 110 along the shape of the heating element 120.

[0101] A PTC heater is a heater that uses a resistive element that exhibits a sharp increase in resistance and a lack of electron flow (PTC characteristic) when a certain temperature (called the Curie temperature) is reached. By effectively utilizing the PTC characteristic, a PTC heater can maintain the temperature below a certain level without requiring a control device to stop heating when the temperature exceeds a predetermined level. The heating unit 120 can also be a PTC heater using barium titanate (BaTiO3), which has PTC characteristics, as the resistive element. In this case, the heating unit 120 can set the Curie temperature of the barium titanate to 350°C, thus enabling the aerosol generating article 200 to be heated at an appropriate temperature below 350°C.

[0102] Figure 5 This is a conceptual diagram of a heating control system 1200 that controls the heating of the heating unit 120. The heating control system 1200 includes the heating unit 120, the control unit 910, and the power supply unit 920.

[0103] In the illustrated example, the heating section 120 is schematically shown in a perspective view. A protrusion 125 is formed on one side of the heating section 120 along its length. The heating section 120 is inserted into the aerosol generating article 200 through the protrusion 125. Therefore, the side of the heating section 120 where the protrusion 125 is formed becomes the side closest to the outside when the aerosol generating article 200 is housed in the frame 110, becoming the downstream side of the airflow path during suction. From this viewpoint, in the following embodiments, the side of the heating section 120 where the protrusion 125 is formed in the length direction will be referred to as the downstream side, and its opposite side will be referred to as the upstream side.

[0104] The control unit 910 includes a control device electrically connected to the heating unit 120, which controls the heating of the heating unit 120. The control device includes a processing unit such as a PCB (Printed Circuit Board). This processing unit, consisting of a CPU and memory, controls the operation of the aerosol generating device 100. The control device detects the start of suction. Specifically, the control device detects the user's operation of an input device such as a button or slide switch (not shown). Alternatively, the control device detects the user's suction action using a sensor (not shown). After this detection, the control device applies a voltage for heating using power supplied from the power supply unit 920. Furthermore, the control device terminates heating if termination conditions are met. Termination conditions include a predetermined time elapsed since heating began, or the number of suction actions by the user exceeding a certain value. It should be noted that the heating unit 120 may also be configured to include a metal body inserted into the aerosol generating article 200, with the metal body being inductively heated to heat the aerosol generating article 200. In this case, a metal body is pre-installed in the aerosol generating article 200, and the metal body and the aerosol generating article 200 are housed together in the frame 110. The housing portion 1A constituting the frame 110 can heat the aerosol generating article 200 through the heating portion 120 containing the induction-heated metal body. As described above, from the viewpoint of being able to make flexible designs, the housing portion 1A may also include the heating portion 120, or the metal body housed together with the aerosol generating article 200 in the housing portion 1A may constitute the heating element of the heating portion 120.

[0105] The power supply unit 920 includes a battery electrically connected to the heating unit 120, supplying power to the heating unit 120. The battery is, for example, a lithium-ion battery. The battery can also be charged via an external power source.

[0106] Figure 6A This is a schematic side sectional view showing the aerosol generating article 200 of this embodiment. Figure 6B Is to express Figure 6AThe diagram shows a cross-sectional view (BB view) of the tobacco section 210 orthogonal to the length direction of the aerosol generating article 200. The aerosol generating article 200 can be cylindrical, preferably cylindrical. As long as it can be housed in the frame 110, the end face or the cross-section orthogonal to the length direction of the aerosol generating article 200 can be elliptical or flat. In the illustrated example, the aerosol generating article 200 is cylindrical with the second central axis AX2 as its axis. When the aerosol generating article 200 is inserted into the frame 110 during suction, the initially inserted end is the upstream end 250. Correspondingly, for the aerosol generating article 200, the side with the upstream end 250 is appropriately referred to as the upstream side, and the opposite side is appropriately referred to as the downstream side. The upstream end 250, on the upstream side of the aerosol generating article 200, can be set to a range from the end face to the outer diameter of the end face in the length direction. Here, if the end face is not circular, the outer diameter is set to the maximum diameter passing through the center of the end face. For example, if the end face is elliptical, the outer diameter is set as the major axis of the ellipse. Figure 6A and Figure 6B As shown, the aerosol generator 200 has a tobacco part (inserted part) 210 and a paper tube 220.

[0107] The tobacco section 210 is configured such that one end is the upstream end 250. The tobacco section 210 has a through hole 211 at its center for the insertion of the heating element 120. Furthermore, the tobacco section 210 has a double-layered structure consisting of a flavor-releasing layer 212 and an elastic deformation layer 213 arranged to surround the inserted heating element 120. A wrapping paper 214, which is a sheet-like packaging material, is wound around the outer periphery of the elastic deformation layer 213. A paper tube 220 is positioned downstream of the tobacco section 210 to cool the volatile compounds released from the flavor-releasing layer 212.

[0108] The aroma-releasing layer 212 comprises a tobacco sheet 212A and a non-tobacco sheet 212B disposed around the outer periphery of the tobacco sheet 212A and coated with glycerin or the like. The aroma-releasing layer 212 includes an aroma-generating substrate, which releases aroma-containing aerosols or the like when heated by the heating unit 120. The aroma-generating substrate is a material that imparts a pleasant aroma, preferably tobacco material. The aroma-generating substrate may also contain flavorings. Flavorings are substances that provide aroma and flavor. Flavorings can be natural or synthetic. One type of flavoring or a mixture of multiple flavorings can be used. Furthermore, any type of flavoring can be used, such as essential oils, natural flavorings, synthetic flavorings, or other commonly used flavorings. It can be liquid or solid, and its form is not limited. Additionally, the aroma-generating substrate may contain cooling agents or flavorings. It should be noted that the aroma-releasing layer 212 may consist of only one of the tobacco sheet 212A and the non-tobacco sheet 212B.

[0109] The elastic deformable layer 213 is made of, for example, a non-woven fabric sheet, a corrugated sheet, or a non-tobacco sheet, and is capable of elastic deformation in its thickness direction (i.e., the radial direction of the cylindrical elastic deformable layer 213). When the elastic deformable layer 213 is inserted into the heating part 120, it helps the aerosol generating article 200 to deform along the shape of the heating part 120. Thus, when the heating part 120 is inserted into the through hole 211, the elastic deformable layer 213 elastically deforms relative to the heating part 120 in the thickness direction, making it easy to contact or approach the heating part 120. Therefore, the fragrance releasing layer 212 can be brought into closer contact with or near the heating part 120, and the aerosol generating article 200 can be heated efficiently.

[0110] The tobacco section 210 includes a flavor-releasing layer 212 and an elastic deformation layer 213 arranged to surround the inserted heating section 120, allowing the shape of the aerosol generating article 200 to be easily deformed when the heating section 120 is inserted into the aerosol generating article 200. It should be noted that the cross-sectional shape of the aerosol generating article 200 can be circular or elliptical.

[0111] Tobacco sheet 212A may contain, for example, tobacco and polyols. Two or more polyols may be used alone or in combination in tobacco sheet 212A. Polyols may also be added to the aforementioned elastic deformation layer 213. Tobacco sheet 212A can be formed into a sheet by mixing a binder with powdered tobacco and polyols. It should be noted that non-tobacco sheet 212B may also contain a flavor-generating substrate.

[0112] like Figure 1 、 Figure 2 and Figure 4 As shown, first shape portions 50A and 50B are formed in the frame 110. The first shape portions 50A and 50B each have a first shape that is a protruding shape. The first shape protrudes in a direction away from the side wall 111 or the bottom wall 112. Figure 4As shown, protruding ends 55A and 55B are formed at the protruding front ends of the first shape portions 50A and 50B, respectively. When the aerosol generating article 200, before the second shape portion 3000 is formed, is housed in the frame 110, the protruding ends 55A and 55B abut against the upstream end 250 of the aerosol generating article 200. Through this abutment, the movement of the upstream end 250 of the aerosol generating article 200 in the insertion direction is hindered. Based on the shape of the protruding ends 55A and 55B, the upstream end 250 is folded into the inside of the aerosol generating article 200 by the reaction force of the force pressing the protruding ends 55A and 55B. The folded-in portion of the upstream end 250 becomes the second shape portion 3000. Here, "folded in" means that the upstream end 250 is deformed not only in the radial direction but also in the insertion direction. Hereinafter, when the first shape portions 50A and 50B are not distinguished from each other, they are referred to as first shape portions 50 , and when the protruding end portions 55A and 55B are not distinguished from each other, they are referred to as protruding end portions 55 .

[0113] The first shape portion 50 is configured to fold the upstream end portion 250 of the aerosol generating article 200 into the inside of the aerosol generating article 200. The first shape portion 50 functions as a folding portion for folding the upstream end portion 250 into the inside of the aerosol generating article 200. When the aerosol generating article 200 is housed in the frame 110, the upstream end portion 250 becomes the end located on the bottom wall 112 side of the aerosol generating article 200. The first shape portion 50 is capable of folding the upstream end portion 250 into the inside of the aerosol generating article 200, at least when the upstream end portion 250 of the aerosol generating article 200 inserted into the frame 110 is not folded in.

[0114] The inventors discovered that when the upstream end 250 is folded into the inside of the aerosol generating article 200, the aerosol generating article 200 is less likely to remain in the frame 110 when the user removes it from the frame 110. This suppresses the degradation of heating efficiency caused by a portion of the heated fragrance generating substrate or other aerosol generating article 200 adhering to the heating unit 120. Furthermore, it reduces the frequency of cleaning the inside of the frame 110, making maintenance of the aerosol generating apparatus 100 easier. These effects are achieved without requiring a complex or large-scale aerosol generating apparatus 100 according to this embodiment.

[0115] The first shaping portion 50 preferably folds the upstream end 250 of the aerosol generating article 200 toward the heating portion 120, particularly toward the central axis extending along the length direction of the heating portion 120. For example, when the heating portion 120 is disposed on the first central axis AX1 of the storage portion 1A formed by the frame 110, the first shaping portion 50 can be configured to fold the upstream end 250 radially inward. In such a structure, when the aerosol generating article 200 is removed from the frame 110, the folded upstream end 250 retains and pushes out the contents of the aerosol generating article 200 disposed between the wrapping paper 214 and the heating portion 120, thus more reliably preventing the contents from remaining inside the frame 110.

[0116] The first shape portion 50 is positioned at the bottom 1B of the storage portion 1A, where it connects to the side wall 111 and bottom wall 112 of the frame 110. A protruding end 55 is located in the first shape portion 50 on the opposite side of the bottom wall 112, i.e., the downstream side. Therefore, when the aerosol generating article 200 is inserted through the opening 115 of the frame 110, the protruding end 55 faces the upstream end 250 of the aerosol generating article 200. When the aerosol generating article 200 does not have a second shape portion 3000, the protruding end 55 can abut against the upstream end 250 and can be folded into the upstream end 250 to form the second shape portion 3000. Therefore, the user does not need a special operation to form the second shape portion 3000. It should be noted that as long as the second shape portion 3000 can be formed at the upstream end 250, the first shape portion 50 can be positioned to connect to either the side wall 111 or the bottom wall 112 of the frame 110. It should be noted that the first shape portion 50 can be formed as part of the sidewall 111 and the bottom wall 112.

[0117] In this embodiment, the protruding end 55 is formed in a linear or strip shape on the surface of the first shaped portion 50. This has the following advantages: When the wider protruding end 55 abuts against the upstream end 250 of the aerosol generating article 200, the contents of the aerosol generating article 200 move in a direction intersecting the direction of the pressing of the protruding end 55 (e.g., along the Y-axis), and the upstream end 250 expands. In this case, when the aerosol generating article 200 is removed from the frame 110, the contents cannot be retained by the upstream end 250, and the contents fall off from the expanded upstream end 250, easily remaining in the frame 110. By abutting the aerosol generating article 200 with the linear or strip-shaped protruding end 55, the upstream end 250 does not expand compared to the wider protruding end 55, making it less likely for the contents to remain in the frame 110 when the aerosol generating article 200 is removed. It should be noted that as long as the second shape portion 3000 can be formed at the upstream end 250, the shape of the protruding end 55 is not particularly limited and can be composed of any plane or curved surface.

[0118] Preferably, the surface of the first shaped portion 50 constituting the protruding end 55 is inclined relative to the first central axis AX1 of the receiving portion 1A. Preferably, the protruding end 55 is inclined such that the tangential plane of the protruding end 55 intersects the first central axis AX1 on the side closer to the bottom wall 112 (upstream side) than the protruding end 55. Here, "inclined" means that the protruding end 55 is neither perpendicular to nor parallel to the first central axis AX1. Considering manufacturing errors, etc., it is preferable that the protruding end 55 is inclined at 5 degrees or more in the direction perpendicular to the first central axis AX1. By inclining the protruding end 55 in this way, when the aerosol generating article 200 without the second shaped portion 3000 is inserted into the frame 110, the upstream end 250 can be forced inward toward the aerosol generating article 200 to form the second shaped portion 3000. Therefore, when the aerosol generating article 200 is removed from the frame 110, the contents of the aerosol generating article 200 are more reliably less likely to remain in the frame 110.

[0119] The angle formed by the first central axis AX1 of the storage section 1A and the tangent plane of the protruding end 55 is defined as the tilt angle θ. The tilt angle θ is greater than 0 degrees and less than 90 degrees. The tilt angle θ is preferably 30 degrees or more. The larger the tilt angle θ, the closer it comes into contact with the protruding end 55, which is at an angle close to perpendicular to the insertion direction of the aerosol generating article 200. Therefore, when the aerosol generating article 200 without the second shape portion 3000 is inserted into the frame 110, it makes it easier to fold in the upstream end 250. The tilt angle θ is preferably 60 degrees or less. When the tilt angle θ is too large, it is difficult for the aerosol generating article 200 to fold inward, and the contents cannot be retained when the aerosol generating article 200 is removed from the frame 110. The tilt angle θ is more preferably in the range of 30 degrees or more and 60 degrees or less. It should be noted that when the protruding end 55 is curved or formed in a stepped shape, and the tilt angle θ takes multiple values, either continuously or discretely, the entire tilt angle θ or a part of it can be set within the above range.

[0120] The shape of the first shape portion 50 is not particularly limited as long as the second shape portion 3000 can be formed by applying force to the upstream end 250 of the aerosol generating article 200, which does not have a second shape portion 3000, through the first shape portion 50. The first shape portion 50 is preferably leaf-shaped. As a result, a narrower protruding end 55 can be formed, and the expansion of the upstream end 250 due to pressure from portions other than the protruding end 55 of the first shape portion 50 on the aerosol generating article 200 can be suppressed.

[0121] like Figure 1 and Figure 4As shown, preferably, the first shape of the first shaped portion 50 includes a sharp shape that tapers radially towards the first central axis AX1. If the first shaped portion 50 has such a sharp shape, the contents of the aerosol generating article 200 can be pushed out in a direction intersecting the pressing direction of the protruding end 55 (e.g., along the Y-axis), thus suppressing the expansion of the upstream end 250. Therefore, when the protruding end 55 applies force inward to the upstream end 250 of the aerosol generating article 200, the upstream end 250 is less likely to expand. Consequently, when the aerosol generating article 200 is removed from the frame 110, the contents are less likely to remain in the frame 110.

[0122] like Figure 2 As shown, the height along the first central axis AX1 is defined as the first height H10, and the width of the first shape in a certain direction at the first height H10 position is defined as the first width W10. In the illustrated example, the first width W10 in the width direction is shown. Preferably, the first width W10 gradually decreases or gradually increases along the first central axis AX1 in the radial, circumferential, or other directions. In the illustrated example, the first width W10 in the width direction gradually increases upstream along the first central axis AX1. In this way, by preventing abrupt changes in the first shape, sharp parts are not formed, and damage can be suppressed when the aerosol generating article 200 comes into contact with the first shape.

[0123] As long as the second shape portion 3000 can be formed at the upstream end 250 of the aerosol generating article 200 by the first shape portion 50, the number of first shape portions 50 disposed in the storage portion 1A is not particularly limited, and there can be more than one. From the viewpoint that the contents of the aerosol generating article 200 can be held more reliably by having multiple second shape portions 3000 at the upstream end 250, it is preferable to provide multiple first shape portions 50 in the storage portion 1A. In this case, from the same viewpoint, it is preferable that the upstream end 250 is folded in from multiple directions, and therefore, it is preferable that, like the first shape portions 50A and 50B, multiple first shape portions 50 are provided inside the frame 110 at different circumferential positions relative to the first central axis AX1.

[0124] The distance between the two first-shaped portions 50A and 50B in a certain direction along the bottom wall 112, that is, along the XY plane, is referred to as the shape portion distance D1. The width of the heating portion 120 in this direction is referred to as the heating portion width W1. In the illustrated example, the shape portion distance D1 and the heating portion width W1 are measured along the X-axis direction. Thus, when the plurality of first-shaped portions 50A and 50B are arranged in opposing positions with the heating portion 120 interposed therebetween, the heating portion width W1 is preferably at least 60% of the shape portion distance D1, and more preferably at least 70% of the shape portion distance D1, in a certain direction along the bottom wall 112. By shortening the distance between the first-shaped portion 50 and the heating portion 120, the upstream end 250 of the aerosol-generating article 200 housed in the frame 110 can be folded in close to the heating portion 120 regardless of the width of the aerosol-generating article 200. Therefore, when the aerosol-generating article 200 is removed from the upstream end 250, the contents are more reliably less likely to remain inside the frame 110.

[0125] In the example shown in the figure, the first-shaped portions 50A and 50B are respectively arranged along the direction in which the plate-shaped heater constituting the heating portion 120 extends, that is, the X-axis direction. Thus, preferably, the first-shaped portion 50 is arranged along the direction in which the heating portion 120 extends at the bottom portion 1B of the storage portion 1A. This shortens the distance between the first-shaped portion 50 and the heating portion 120. Furthermore, the aerosol generating device 100 can be formed thinner in the thickness direction, making it compact. It should be noted that as long as the second-shaped portion 3000 can be formed at the upstream end portion 250 by the first-shaped portion 50, the position of the first-shaped portion 50 can be appropriately adjusted.

[0126] The first-shaped portion 50A is disposed opposite one end of the heating portion 120 on the negative side in the X-axis direction (width direction). The first-shaped portion 50B is disposed opposite one end of the heating portion 120 on the positive side in the X-axis direction. In this manner, the first-shaped portion 50 can be disposed at a position between the bottom wall 112 and one end of the plate-shaped heating portion 120, preferably opposite both ends of the plate-shaped heating portion 120. This further shortens the distance between the first-shaped portion 50 and the heating portion 120. Furthermore, the aerosol generating device 100 can be made thinner in the thickness direction, making it more compact.

[0127] like Figure 3As shown, the plate-shaped heater constituting the heating section 120 has a first principal surface 1201 perpendicular to the thickness direction (Y-axis direction) and a second principal surface 1202 formed on the back side of the first principal surface 1201. The holding flange 30 is formed on the side wall 111, facing the first principal surface 1201 and the second principal surface 1202. Meanwhile, the first-shaped portions 50A and 50B are arranged along the width direction of the heating section 120. When the first-shaped portions 50A and 50B press the upstream end portion 250 along the width direction, the contents of the aerosol-generating product 200 can be pushed out in the thickness direction intersecting the pressing direction. Therefore, by applying a force inward to the aerosol-generating article 200 along the thickness direction, the holding flange 30 can suppress expansion of the upstream end portion 250, thereby preventing the contents from remaining in the housing 110 when the aerosol-generating article 200 is removed from the housing 110. The clamping flange 30 may be arranged to face only one of the first main surface 1201 and the second main surface 1202 .

[0128] The material of the first shaped portion 50 is not particularly limited as long as it can withstand the heat of the heating unit 120 and can be processed into its shape. The first shaped portion 50 can be formed of a resin such as PC, ABS resin, PEEK or a polymer alloy, or a metal such as aluminum. The method for forming the first shaped portion 50 is not particularly limited. After the side walls 111 and the bottom wall 112 of the frame 110 are formed, the first shaped portion 50 can be attached by bonding or the like. Alternatively, the first shaped portion 50 can be formed integrally with the side walls 111 and the bottom wall 112 by resin molding or die casting.

[0129] Figure 7 1A is a side view schematically showing the aerosol-generating article 200 in which second-shaped portions 3000A and 3000B are formed by contact with the first-shaped portions 50A and 50B of the storage portion 1A, respectively. Figure 8 Yes Figure 7 A conceptual diagram of the end face of the aerosol generating article 200 on the bottom wall 112 side (upstream side) (schematic side view viewed from direction CC). Hereinafter, for ease of understanding, the aerosol generating article 200 in the state of being stored in the storage section 1A will be appropriately referred to as the stored article 2000. In the stored article 2000, the second shape portions 3000A and 3000B are formed at both ends of the upstream side end portion 250 of the tobacco section 210 along the width direction (X-axis direction). In the following embodiments, when the second shape portions 3000A and 3000B are not distinguished, they are referred to as the second shape portion 3000. The second shape portions 3000A and 3000B are portions that are folded inwardly of the stored article 2000 by the upstream side end portion 250 abutting against the first shape portions 50A and 50B when inserted into the storage section 1A. In Figure 7 In FIG. 1 , an example of the outline of the folded portion of the upstream end portion 250 is schematically shown by a two-dot chain line.

[0130] exist Figure 8 , the outline of the cross section of the heating section 120 is schematically indicated by a dotted line. The stored article 2000 is expanded in the width direction (X-axis direction) of the extension of the heating section 120 by being inserted into the heating section 120. At the upstream end 250, the pressed portions 3100A and 3100B, against which the protruding ends 55A and 55B respectively abut, are pressed more strongly and are applied to the inner side of the stored article 2000. In this embodiment, the protruding end 55 is linear or strip-shaped, so the pressed portions 3100A and 3100B are also linear or strip-shaped. Furthermore, since the protruding end 55 has a convex portion, the second shape portion 3000 has a concave portion. By utilizing the convex portion, the stored article 2000 can be easily deformed. In this way, the upstream end 250 is configured to have a second shape corresponding to the first shape when the aerosol-generating article 200 is stored in the storage section 1A. The second shape provides a structure that prevents the contents from remaining in the storage portion 1A when the aerosol-generating article 200 is taken out of the storage portion 1A.

[0131] The surface of the second-shaped portion 3000 is inclined relative to the longitudinal direction of the aerosol-generating article 200 or the insertion direction (Z-axis direction) of the aerosol-generating article 200. Specifically, at least a portion of the surface of the second-shaped portion 3000 is inclined such that a tangent plane TP of the at least portion intersects the second central axis AX2 at the end surface side of the at least portion closer to the upstream end 250. Therefore, the second-shaped portion 3000 functions as a retaining portion for retaining contents such as the flavor-releasing layer 212 relative to the second-shaped portion 3000 in the insertion direction. This retention allows the stored article 2000 to be removed without leaving any contents in the storage portion 1A. Thus, the aerosol-generating article 200 of this embodiment is configured such that, when stored in the storage portion 1A, the surface of the second-shaped portion 3000 is inclined relative to the insertion direction, thereby serving as a retaining portion. Note that, in the illustrated example, the second-shaped portion 3000 partially covers the tobacco sheet 212A, the non-tobacco sheet 212B, and the elastically deformable layer 213. However, when the stored item 2000 is removed from the frame 110, the extent of the end face of the aerosol generating item 200 covered by the second shape part 3000 is not particularly limited, as long as the effect of preventing the contents from remaining in the storage part 1A to the desired extent can be achieved.

[0132] The surface of the second shape portion 3000 is preferably formed from the packaging material, i.e., the wrapping paper 214, of the upstream end 250 of the packaging. This allows for the efficient and cost-effective manufacture of an aerosol generation system 10 where, when the aerosol-generating article 200 is removed from the storage portion 1A, the contents are unlikely to remain in the storage portion 1A. Preferably, the aerosol-generating article 200 and the first shape portion 50 are configured such that, when the aerosol-generating article 200 is stored in the storage portion 1A, it is folded inward toward the upstream end 250 of the wrapping paper 214, which is the packaging material. This allows for more reliable suppression of the contents of the stored article 2000 remaining in the storage portion 1A when the stored article 2000 is removed from the storage portion 1A. Furthermore, by folding in the packaging material, an aerosol-generating article 200 with this effect can be easily formed.

[0133] In the aerosol generating article 200, when the aerosol generating article 200 is housed in the housing section 1A, the basis weight of the packaging material in the portion forming the second shape section 3000 is preferably 20 gsm or more, more preferably 100 gsm or more. The higher the basis weight, the stronger the packaging material, enabling it to firmly hold the contents of the housed article 2000 and strongly suppressing positional shifts. The basis weight of the packaging material in the aforementioned portion forming the second shape section 3000 is preferably 200 gsm or less. If the basis weight is too high, it may cause adverse effects such as difficulty in forming the second shape section 3000 and inability to compactly form the aerosol generating article 200. As will be described later, when the wrapping paper 214 has multiple layers, the total basis weight of the overlapping layers can be used as the aforementioned basis weight of the packaging material.

[0134] The second shape portion 3000A is formed at one end of the stored item 2000 on the negative side in the X-axis direction (width direction). The second shape portion 3000B is formed at one end of the stored item 2000 on the positive side in the X-axis direction. Thus, preferably, the aerosol generating article 200 and the first shape portion 50 are configured such that the second shape portions 3000 are arranged on both sides of the upstream end 250 in a direction perpendicular to the length direction of the stored item 2000. As a result, when the stored item 2000 is removed from the storage section 1A, the second shape portions 3000 retain the contents of the stored item 2000 on both sides of the upstream end 250 of the stored item 2000, which can more reliably prevent the contents from remaining in the storage section 1A.

[0135] like Figure 7As shown, the height along the second central axis AX2 is defined as the second height H20, and the width of the second shape in a certain direction at the second height H20 is defined as the second width W20. In the illustrated example, the second width W20 in the width direction is represented. Preferably, in the radial, circumferential, or other directions, the second width W20 increases with the end face towards the upstream side along the second central axis AX2. In the illustrated example, the second width W20 in the width direction gradually increases towards the upstream side along the second central axis AX2. Therefore, for a larger range of contents in the stored item 2000, when the stored item 2000 is removed from the storage section, it is possible to prevent contents from remaining in the storage section 1A.

[0136] like Figure 4 As shown, from the perspective of smooth folding, the housing portion 1A formed by the frame 110 preferably includes a non-folded portion 155 that is adjacent to the first shape portion 50 in the circumferential direction relative to the central axis AX1 and does not fold in the upstream end portion 250. In other words, the first shape portion 50 preferably does not have a protruding end portion 55 that is continuous throughout the entire circumference.

[0137] Next, the relationship between the aerosol-generating article 200, the housing 110, and the heating unit 120 when the aerosol-generating article 200 is housed in the aerosol-generating device 100, that is, when the aerosol-generating article 200 is inserted from one end (downstream side) to the other end (upstream side) of the housing 110, will be described. Figures 9 to 11 1 is a cross-sectional view showing a state where the aerosol generating article 200 is housed in the aerosol generating device 100. Figures 9 to 11 In FIG. 2 , the flavor-releasing layer 212 and the elastically deformable layer 213 of the aerosol-generating article 200 are shown as a single annular sheet 215 .

[0138] Figure 9 The cross section of the heating unit 120 in the width direction and the cross section of the inlet 22 of the shaping guide 20 perpendicular to the longitudinal direction of the frame 110 are shown when the aerosol-generating article 200 passes through the shaping guide 20 . Figure 10 The cross section of the heating unit 120 in the width direction and the cross sections of the middle and other end portions of the holding flange 30 perpendicular to the longitudinal direction of the frame 110 illustrate a state where the aerosol-generating article 200 passes through the holding flange 30 . Figure 11 The cross section of the heating unit 120 in the width direction and the cross section near the other end of the heating unit 120 perpendicular to the longitudinal direction of the housing 110 show the aerosol-generating article 200 stored in a predetermined storage position of the housing 110 .

[0139] like Figure 9As shown, the shaping guide 20 has a cone portion 21, an inlet portion 22, and a deformable portion 23. The cone portion 21 is configured as a side-expanding tube facing one end of the frame 110, guiding the aerosol generating article 200 into the aerosol generating device 100. The inlet portion 22 is configured to be located at the end of the frame 110 and has an elliptical cross-section, with a major axis greater than or equal to the major axis of the aerosol generating article 200 housed behind the frame 110, and a minor axis approximately the same as the diameter of the aerosol generating article 200 housed in front of the frame 110. Furthermore, the deformable portion 23 is configured to be located on the inner circumferential surface of the frame 110 and has an elliptical cross-section, with a minimum inner circumference approximately equal to the outer circumference of the aerosol generating article 200. Thus, when the aerosol-generating article 200 passes through the shaping guide 20 , the entire circumference of the aerosol-generating article 200 contacts the deforming portion 23 , and thus the cross-sectional shape of the aerosol-generating article 200 can be deformed along the shape of the inlet portion 22 .

[0140] like Figure 10 As shown, the heating section 120 is configured as a protrusion 125 with a pointed end, which widens towards the other end. Therefore, as the aerosol generating article 200 is inserted through the shaping guide 20, the shape of the aerosol generating article 200 deforms along the shape of the heating section 120. Specifically, the aerosol generating article 200 expands in the width direction of the heating section 120. This allows the aerosol generating article 200 to fit tightly against the heating section 120, improving the heat transfer efficiency from the heating section 120 to the aerosol generating article 200. Furthermore, by expanding the aerosol generating article 200 within the heating section 120, it is possible to prevent the aerosol generating article 200 from falling off.

[0141] In the illustrated example, the heating unit 120 has a flat plate shape, which deforms the outer shape of the aerosol-generating article 200 inserted into the frame 110 into an elliptical cross-section. In this case, the major diameter of the aerosol-generating article 200 housed in the frame 110 is longer than the diameter of the aerosol-generating article 200 before being housed in the frame 110, and the minor diameter of the aerosol-generating article 200 housed in the frame 110 is shorter than the diameter of the aerosol-generating article 200 before being housed in the frame 110. By deforming the outer shape of the aerosol-generating article 200 inserted into the frame 110 into an elliptical cross-section by the heating unit 120, the distance occupied by the aerosol-generating article 200 in the short direction of the frame 110 is shortened. Consequently, the frame 110 can be made thinner. Furthermore, by deforming the outer shape of the aerosol-generating article 200 inserted into the frame 110 into an elliptical cross-section by the heating unit 120, the contact area between the heating unit 120 and the aerosol-generating article 200 can be increased. Therefore, the heat transfer efficiency from the heating unit 120 to the aerosol generating article 200 can be improved. Furthermore, by applying force to the clamping flange 30, the aerosol generating article 200 can be brought into closer contact with the heating unit 120, further improving heat transfer efficiency. Moreover, by applying force to the clamping flange 30, the aerosol generating article 200 can be prevented from falling off.

[0142] like Figure 11 As shown, when the upstream end 250 of the aerosol-generating article 200 reaches the bottom wall 112, the first-shaped portions 50A and 50B fold the upstream end 250 inward to form second-shaped portions 3000A and 3000B. Furthermore, when the aerosol-generating article 200 is stored in the predetermined storage position of the housing 110, an air layer 40 is formed between the aerosol-generating article 200 and the housing 110, extending over the entire circumference of the aerosol-generating article 200. The air layer 40 has a low thermal conductivity and thus provides thermal insulation between the aerosol-generating article 200 and the housing 110, thereby reducing the energy required to heat the aerosol-generating article 200. Furthermore, the inlet portion 22 abuts the aerosol-generating article 200 over its entire outer circumference, sealing the air layer 40. This suppresses convection of air within the air layer 40.

[0143] In the aerosol generation system 10 of this embodiment, a first-shaped portion 50 with a protruding first shape is formed at the bottom 1B of the receiving portion 1A. The aerosol generation article 200 has an upstream end portion 250 that is inserted into the receiving portion 1A. The upstream end portion 250 is configured to include a second-shaped portion 3000 having a second shape corresponding to the first shape when the aerosol generation article 200 is received in the receiving portion 1A. At least a portion of the surface of the second-shaped portion 3000 is inclined relative to the length direction of the aerosol generation article 200. This prevents the aerosol generation apparatus 100 from becoming too complex or too large, and by using the second shape corresponding to the protruding first shape, it prevents the contents of the aerosol generation article 200 from remaining in the receiving portion 1A when the aerosol generation article 200 is removed from the receiving portion 1A. This reduces the need for cleaning and maintenance of the aerosol generation apparatus 100. Furthermore, by suppressing the adhesion of the aerosol generation article 200 to the heating portion 120, the deterioration of heating efficiency can be suppressed.

[0144] In the aerosol generation system 10 of this embodiment, the upstream end 250 of the aerosol generation article 200 does not have a second shape portion 3000. The upstream end 250 and the first shape portion 50 are configured such that when the aerosol generation article 200 is inserted into the receiving part 1A, the upstream end 250 is pressed by the first shape portion 50 to form the second shape portion 3000. Therefore, it is not necessary to pre-process the second shape portion 3000 in the aerosol generation article 200, and when the aerosol generation article 200 is removed from the receiving part 1A, it is possible to prevent the contents of the aerosol generation article 200 from remaining in the receiving part 1A.

[0145] The following modifications are also within the scope of the present invention and can be combined with the above-described embodiment or other modifications. In the following modifications, parts and the like representing the same structures and functions as those in the above-described embodiment are referenced with the same reference numerals and description thereof is omitted as appropriate.

[0146] (Variation Example 1-1)

[0147] In the above-described embodiment, the protruding end portion 55 of the first shape portion 50 may be inclined more steeply relative to the bottom wall 112 as it becomes farther away from the first central axis AX1 .

[0148] Figure 12This is a schematic side sectional view showing the structure of the aerosol generating apparatus 100A in the aerosol generating system of this modified example. The aerosol generating apparatus 100A has the same structure as the aerosol generating apparatus 100 of the above embodiment, but differs from the aerosol generating apparatus 100 in that it has first shaped portions 51A and 51B, each having a protruding end 551A and 551B, instead of first shaped portions 50A and 50B. When referring to the indistinguishable first shaped portions 51A and 51B, they are referred to as first shaped portion 51. When referring to the indistinguishable protruding ends 551A and 551B, they are referred to as protruding ends 551. The first shaped portion 51 has the same (not shown) bottom surface as the first shaped portion 50 of the above embodiment, but the protruding end 551 differs from the protruding end 55 of the above embodiment and is an arched shape protruding upstream. Therefore, it is possible to provide an aerosol generating apparatus 100A that forms a second shape portion 3000 through a first shape portion 51 and is less likely to hinder the insertion of the aerosol generating article 200 into the frame 110.

[0149] (Variation 1-2)

[0150] In the above embodiment, the protruding end 55 of the first shaped portion 50 may become more gently inclined relative to the bottom wall 112 the further away from the first central axis AX1.

[0151] Figure 13 This is a schematic side sectional view showing the structure of the aerosol generating apparatus 100B of the aerosol generating system of this modified example. The aerosol generating apparatus 100B has the same structure as the aerosol generating apparatus 100 of the above embodiment, but differs from the aerosol generating apparatus 100 in that it has first shaped portions 52A and 52B, each having a protruding end 552A and 552B, instead of first shaped portions 50A and 50B. When referring to the indistinguishable first shaped portions 52A and 52B, they are referred to as first shaped portion 52. When referring to the indistinguishable protruding ends 552A and 552B, they are referred to as protruding ends 552. The first shaped portion 52 has the same bottom surface (not shown) as the first shaped portion 50 of the above embodiment, but the protruding end 552 differs from the protruding end 55 of the above embodiment, becoming an arched shape protruding downstream. Therefore, it is possible to provide an aerosol generating apparatus 100B where the protruding end 552 easily abuts against the upstream end 250, enabling more reliable formation of the second shaped portion 3000.

[0152] (Variation 1-3)

[0153] In the above embodiments, the heating part 120 may also be a needle-type heater.

[0154] Figure 14 This is a schematic side sectional view of the aerosol generating apparatus 100C of the aerosol generating system of this modified example. Figure 15 yes Figure 14 DD cross-sectional view. Figure 14 The side section is equivalent to Figure 15 The EE cross section. The aerosol generating apparatus 100C has the same structure as the aerosol generating apparatus 100 in the above embodiment, but it differs from the aerosol generating apparatus 100 in that it has a heating section 121 instead of a heating section 120 and a frame 110A instead of a frame 110.

[0155] The heating element 121 extends along the first central axis AX1 and includes a heating element body 121A and a protrusion 125. A sharp-shaped protrusion 125 is formed on the downstream side of the cylindrical heating element body 121A. A heating element is disposed within the heating element body 121A, which is located inside the storage portion 1A formed by the frame 110A. Thus, the heating element 121 can heat the aerosol generating article 200, into which the heating element 121 is inserted, from the inside. The heating element is not particularly limited as long as it can heat the aerosol generating article 200; for example, it can be an electric heating wire or a metal body that heats up through induction. The shape of the heating element body 121A is not particularly limited; it can be cylindrical or polygonal. Preferably, the heating element body 121A is cylindrical to facilitate smooth insertion into the aerosol generating article 200. Furthermore, the heating element body 121A can also be pre-installed inside the aerosol generating article 200. In this case, the storage section 1A formed by the frame 110A can heat the aerosol generating article 200 by induction heating the heating section main body 121A, which is disposed together with the aerosol generating article 200 in the storage section 1A.

[0156] The frame 110A includes a side wall 111A, a bottom wall 112A, and first shape portions 53A, 53B, and 53C. The bottom wall 112A and the side wall 111A located opposite the upstream end 250 of the aerosol generating article 200 housed in the housing 1A form the bottom 1B. The first shape portions 53A, 53B, and 53C each have protruding ends 553A, 553B, and 553C, respectively. Hereinafter, when referring to the first shape portions 53A, 53B, and 53C without distinction, they will be referred to as the first shape portion 53. And when referring to the protruding ends 553A, 553B, and 553C without distinction, they will be referred to as the protruding end 553. The shape of the frame 110A is not particularly limited as long as it can accommodate the aerosol generating article 200 inserted into the heating unit 121. However, from the viewpoint that the upstream end 250 is smoothly folded in by the multiple first shape portions 53, it is preferable that the side wall 111A and the bottom wall 112A are rotationally symmetrical about the first central axis AX1. More preferably, as in the example shown in the figure, the side wall 111A is cylindrical and the bottom wall 112A is circular.

[0157] The shape of the first shaped portion 53 is similar to that of the first shaped portion 50 in the aforementioned embodiment and is not particularly limited as long as the second shaped portion 3000 can be formed at the upstream end 250. In this variation, the first shaped portion 53 is connected to the side wall 111A and the bottom wall 112A and is three-dimensionally symmetrical about the first central axis AX1, with three first shaped portions 53A, 53B, and 53C formed every 120 degrees. The number of first shaped portions 53 can be one, two, or four or more. The protruding end 553 has the same shape as the protruding end 55 in the aforementioned embodiment, but is not limited thereto.

[0158] As in this modified example, even when the heating section 121 is a needle-type heater, the frame 110A can be provided in the first shape section 53, and the second shape section 3000 can be formed at the upstream end 250 of the aerosol generating article 200. As a result, when the aerosol generating article 200 is removed from the frame 110A, the contents of the aerosol generating article 200 can be prevented from remaining in the frame 110A.

[0159] (Variations 1-4)

[0160] In the above embodiment, the heating unit 120 heats the aerosol-generating article 200 from within the aerosol-generating article 200, thereby providing internal heating. However, the heating unit 120 may be disposed on at least one of the side wall 111 and the bottom wall 112 of the housing 110, thereby heating the aerosol-generating article 200 from the outside of the aerosol-generating article 200 housed in the housing 110. Even in such a case, by folding the upstream end portion 250 of the aerosol-generating article 200 by the first shape portion 50, it is possible to prevent a portion of the aerosol-generating article 200 from remaining in the housing 110 when the aerosol-generating article 200 is removed from the housing 110. In particular, it is possible to prevent a portion near the end surface of the upstream end portion 250 from adhering to the bottom wall 112 or the like.

[0161] Second Implementation Method

[0162] The aerosol generating system 10A of the second embodiment has substantially the same structure as the aerosol generating system 10 of the first embodiment. However, unlike the aerosol generating system 10 of the first embodiment, a second shaped portion is pre-formed on the aerosol-generating article. Parts identical to those of the first embodiment are referenced with the same reference numerals as those of the first embodiment, and description thereof is omitted as appropriate.

[0163] Figure 16 This is a schematic diagram representing the aerosol generation system 10A. Figure 17 yes Figure 16 A schematic side view of the aerosol generating item 200A of the FF. Figure 18 yes Figure 16A cross-sectional view of the aerosol generating article 200A of the GG. The aerosol generating system 10A includes an aerosol generating device 100 and an aerosol generating article 200A.

[0164] The aerosol generating article 200A includes a tobacco section 210A and a paper tube 220A. The tobacco section 210A includes an upstream end 351, a downstream end 352, and second shape sections 300A and 300B. Hereinafter, when referring to the second shape sections 300A and 300B without distinction, it will be referred to as the second shape section 300. The tobacco section 210A has a structure that is substantially the same as that of the tobacco section 210 in the above embodiment, but it differs from the tobacco section 210 in that it has the second shape section 300 before being housed from the aerosol generating article 200A into the housing section 1A.

[0165] like Figure 16 and 17 As shown, the second shaped portion 300 is formed at the upstream end 351 of the tobacco portion 210A. In the illustrated example, the wrapping paper 214 disposed across the tobacco portion 210A and the paper tube 220A is folded onto the outer surface of the aerosol-generating article 200A to form the second shaped portion 300.

[0166] The second shape portion 300 suppresses the displacement of the contents disposed in the aerosol generating article 200A. The second shape portion 300 can suppress the movement of the elastic deformation layer 213 or the flavor releasing layer 212 in the tobacco portion 210A in the longitudinal direction. As a result, it is possible to prevent the contents of the tobacco portion 210A from being misplaced relative to the heating portion 120 or from falling off the aerosol generating article 200A, and to prevent the aerosol generating system 200A from malfunctioning due to these reasons.

[0167] The second shape portion 300 is disposed at the upstream end portion 351. The upstream end portion 351 is the initially inserted end when the aerosol generating article 200A is inserted into the receiving portion 1A. Therefore, the second shape portion 300 retains the contents of the aerosol generating article 200A at its upstream position, thus preventing the contents from moving upstream. Furthermore, when the aerosol generating article 200A is removed from the receiving portion 1A, the second shape portion 300 retains the contents and moves with the contents, thus preventing the contents from remaining in the receiving portion 1A.

[0168] The second shape portion 300 is formed on the outer peripheral surface of the upstream end portion 351. Therefore, the second shape portion 300 can be easily formed. For example, the second shape portion 300 can be formed by pressing the component against a packaging material such as wrapping paper 214 disposed on the outer peripheral surface, or by mechanically or manually folding the packaging material. From the same viewpoint, it is preferable that the packaging material is disposed on the side of the columnar tobacco portion 210A, and in the second shape portion 300, the packaging material is folded inward from this side toward the inside of the tobacco portion 210A.

[0169] exist Figure 17 In this example, the second shape portion 300 is folded radially toward the through hole 211 from the wrapping paper 214. Creases 310A and 310B are formed in the second shape portions 300A and 300B, respectively. The second shape portions 300A and 300B are formed by abutting and pressing the wrapping paper 214 with a leaf-shaped component. Creases 310A and 310B are formed by abutting with a linear or strip-shaped tip. When the second shape portion 300 is formed by abutting with a component having a linear or strip-shaped tip, unexpected deformation of the tobacco portion 210A can be suppressed compared to the case of a wider component; therefore, the above structure is preferred. It should be noted that the shape of the second shape portion 300 is not particularly limited as long as it can suppress the displacement of the contents of the aerosol-generating article 200A. For example, the second shape portion 300 does not need to be formed by folding in packaging material, etc. It should be noted that as long as the second shape portion 300 can be formed on the tobacco portion 210A, the shape of the aerosol generating article 200A is not particularly limited. For example, the end face or cross-section orthogonal to the length direction of the aerosol generating article 200A can also be elliptical or... Figure 8 That kind of flat shape.

[0170] The shape of the second shape portion 300 can be the same as that of the second shape portion 3000 in the above-described embodiment. For example, as described below, the second shape portion 300 can also have the same structure as the second shape portion 3000 described above. Thus, the same effect as the above-described embodiment can be achieved.

[0171] Similar to the embodiments described above, preferably, the surface of the second shape portion 300 is formed by the wrapping paper 214, which serves as the packaging material for packaging the aerosol generating article 200A. Preferably, the packaging material has a basis weight of 20 gsm or more and 200 gsm or less in the portion constituting the second shape portion 300. Preferably, the second shape portion 300 has a folded-in portion that extends inward toward the upstream end 351 of the packaging material. Preferably, the surface of the second shape portion 300 is inclined relative to the direction in which the aerosol generating article 200A is inserted into the receiving portion 1A. The width of the second shape (second width W20) in a direction perpendicular to the length direction of the aerosol generating article 200A preferably increases toward the end face side of the upstream end 351 of the aerosol generating article 200A. The second shape portion 300 is preferably arranged on both sides of the upstream end 351 along a direction perpendicular to the length direction of the aerosol generating article 200A.

[0172] In the illustrated example, the aerosol-generating article 200A includes two second-shaped portions 300A and 300B. The number of second-shaped portions 300 in the aerosol-generating article 200A may be one or three or more. Preferably, the number of second-shaped portions 300 is the same as the number of first-shaped portions 50 in the aerosol-generating device 100.

[0173] Preferably, the second shape portion 300 is positioned corresponding to the position of the first shape portion 50, so that when the aerosol generating article 200A is housed in the housing portion 1A, it can be positioned opposite to the first shape portion 50. This suppresses unnecessary deformation of the upstream end portion 351 caused by contact with the first shape portion 50. Therefore, it suppresses adverse effects such as insufficient alignment between the aerosol generating article 200A and the heating portion 120, and reduced heating efficiency.

[0174] like Figure 16 As shown, preferably, the aerosol generating article 200A includes a mark 400. The mark 400 is used to insert the aerosol generating article 200A into the receiving portion 1A with the first shape portion 50 and the second shape portion 300 facing each other. In the illustrated example, the mark 400 is a mark drawn on the outer surface of the aerosol generating article 200A. The shape of the mark 400 is not particularly limited as long as the first shape portion 50 and the second shape portion 300 can be aligned. The mark 400 may be formed on a protrusion or recess of the aerosol generating article 200A, or on a portion with a different color, chroma, or brightness. The mark 400 can suppress adverse effects such as reduced heating efficiency caused by the first shape portion 50 and the second shape portion 300 being positioned in an unexpectedly opposing manner. It should be noted that such a mark can be formed on at least one of the aerosol generating article 200A and the aerosol generating apparatus 100.

[0175] Figure 18 This is a schematic representation of the cross-section of paper tube 220A. Figure 16 A cross-sectional view of the paper tube 220A. The paper tube 220A has a cylindrical wrapping paper 214 and a stop 2140 located inside the wrapping paper 214. In this embodiment, the basis weight of the wrapping paper 214 in the paper tube 220A is preferably 50 g / m³. 2 Above and 150g / m 2 The following is more preferably 50g / m 2 Above and 100g / m 2 From the viewpoint of maintaining an appropriate shape by deforming the wrapping paper 214 relative to the elastic deformation layer 213, it is preferable that the wrapping paper 214 extends from the paper tube 220A to the tobacco section 210A, but is not limited thereto.

[0176] The stop 2140 prevents the elastic deformable layer 213 from moving from the tobacco section 210A toward the paper tube 220A. Specifically, in this embodiment, when viewed in the longitudinal direction, at least a portion of the stop 2140 of the paper tube 220A is located at the same radius as the elastic deformable layer 213. In other words, at least a portion of the stop 2140 is positioned to contact the elastic deformable layer 213 in the longitudinal direction. Therefore, when the heating section 120 is inserted into the through hole 211, even if the heating section 120 applies force to the elastic deformable layer 213 in the direction toward the paper tube 220A, the stop 2140 contacts the elastic deformable layer 213 and can prevent the elastic deformable layer 213 from moving. Therefore, it is possible to suppress the destruction of the aerosol generating article 200A when the heating section 120 is inserted. In this embodiment, the two ends of the stop 2140 are connected to different positions on the inner surface of the cylindrical wrapping paper 214, and the length between its ends can be a piece of paper longer than the diameter of the wrapping paper 214. However, this is not the only possibility; the stop 2140 can be any form capable of preventing the elastically deformable layer 213 from moving from the tobacco section 210A toward the paper tube 220A. For example, the stop 2140 can also be a sheet whose cross-section forms a chord connecting any two points of the wrapper 214. It should be noted that the paper tube 220A may also include a filter or the like that allows flavored aerosols to pass through.

[0177] The upstream end 351 of the aerosol generating article 200A in this embodiment has a second shape portion 300 before being housed in the housing section 1A. Because the second shape portion 300 is pre-formed, when the aerosol generating article 200A is removed from the housing section 1A, the contents of the aerosol generating article 200A can be more reliably prevented from remaining in the housing section 1A. On the other hand, because the aerosol generating apparatus 100 has a first shape portion 50, even if the second shape portion 300 is deformed, the second shape portion 300 can be reformed using the first shape portion 50.

[0178] The following modifications are also within the scope of the present invention and can be combined with the above-described embodiments or other modifications. In the following modifications, parts that have the same structure and function as the above-described embodiments are referred to by the same reference numerals, and descriptions are omitted where appropriate.

[0179] (Variation Example 2-1)

[0180] In the above embodiment, a third shape portion for suppressing the positional displacement of the contents of the aerosol generating article 200A may also be formed at the downstream end 352 of the tobacco portion 210A of the aerosol generating article 200A.

[0181] Figure 19 This is a schematic side sectional view of the aerosol generating article 200B of this modified example. Figure 20 yes Figure 19 The HH cross-sectional view. The aerosol generating article 200B has a structure that is substantially the same as that of the aerosol generating article 200A of the above embodiment, but differs from the aerosol generating article 200A in that it has third shape portions 301A and 301B at the downstream end 352. When referring to the fact that the third shape portions 301A and 301B are not distinguished, they are referred to as the third shape portion 301.

[0182] exist Figure 19 In the diagram, the tobacco section 210B is shown in a cross-sectional view, and the paper tube 220A is shown in a side view. A third shape portion 301 is formed at the downstream end 352 of the tobacco section 210B. The third shape portion 301 is formed by folding the wrapping paper 214 from the side of the tobacco section 210B toward the through hole 211. Therefore, the third shape portion 301 can suppress the contents, such as the elastic deformation layer 213 and the flavor release layer 212, from shifting toward the paper tube 220A. In particular, when the aerosol generating article 200A is housed in the frame 110, the contents of the tobacco section 210B are easily shifted downstream by being dragged by the heating part 120 inserted into the through hole 211, but the third shape portion 301 can hold the contents and suppress this shift.

[0183] The third shape portion 301, except that it is formed at the downstream end 352, can be the same shape and number as the second shape portion 300, or it can be different. In the illustrated example, creases 311A ​​and 311B are formed in the third shape portions 301A and 301B, respectively, but the shape of the third shape portion 301 is not particularly limited as long as it can suppress the displacement of the contents of the aerosol generating article 200B.

[0184] In this modified aerosol generating article 200B, a tobacco section 210B and a paper tube 220A through which the flavoring substance released from the tobacco section 210B passes are arranged along the length direction, and a third shape section 301 is formed at the end of the side of the tobacco section 210B where the paper tube 220A is arranged. This prevents the contents of the aerosol generating article 200B from shifting downstream.

[0185] It should be noted that in the aerosol generating article 200B, a second shape portion 300 and a third shape portion 301 are respectively provided at both ends of the tobacco section 210B along the length direction, but the second shape portion 300 may not be provided at the upstream end 351. In this case, when the aerosol generating article 200B is housed in the housing section 1A via the first shape portion 50 of the aerosol generating device 100, the second shape portion 3000 may be configured to be formed at the upstream end 351.

[0186] (Variation Example 2-2)

[0187] In the above embodiment, three second shape portions 300 may also be formed at the upstream end 351.

[0188] Figure 21 This is a schematic side view of the upstream end portion 351A of the tobacco portion 210C of the aerosol generator 10C of this modified example. Three second shape portions 300C, 300D, and 300E, which are trigonally symmetrical with respect to the second central axis AX2, are formed on the upstream end portion 351A. Although creases 310C, 310D, and 310E are formed on the second shape portions 300C, 300D, and 300E respectively, the shapes of the second shape portions 300C, 300D, and 300E are not limited. The aerosol generating article 200C of this modified example is suitable for heaters with a circular cross-section perpendicular to the length direction, such as needle heaters, but is not limited to this.

[0189] (Variations 2-3)

[0190] In the above embodiments, the packaging material constituting the second shape portion 300 or the third shape portion 301 may also have multiple layers.

[0191] Figure 22This is a cross-sectional view showing the tobacco portion 210A of the wrapping paper 2141 in this modified example. The wrapping paper 2141 is disposed outside the elastic deformable layer 213 and has a first layer 2141A, a second layer 2141B, and a third layer 2141C. The first layer 2141A, the second layer 2141B, and the third layer 2141C overlap. By having multiple layers in the wrapping paper 2141, the contents of the aerosol generating article 200A can be held more firmly by the multiple layers of packaging material, thus suppressing the displacement of the contents. Furthermore, when manufacturing the aerosol generating article 200A, it is easier to form the second shape portion 300 or the third shape portion 301 by adjusting the thickness by overlapping sheets than by using a single thick sheet. Moreover, it is not necessary to prepare sheets of different thicknesses, enabling efficient manufacturing. For example, when using packaging material with a total weight of 200 gsm to form the second shape portion 300, it can be formed using a single sheet with a weight of 200 gsm, but it is preferable to use two sheets of 100 gsm to form the second shape portion 300.

[0192] The embodiments of the present invention have been described above. However, the above-described embodiments are for ease of understanding of the present invention and are not intended to limit the present invention. The present invention can be modified and improved without departing from its spirit, and equivalents are included in the present invention. Furthermore, within the scope of solving at least a portion of the above-described problems or achieving at least a portion of the effects, combinations or omissions of the constituent elements described in the claims and specification are possible.
