DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0011] (First embodiment) FIG. 1 is a cross-sectional view of a cartridge 1 for a smoking article according to a first embodiment of the present invention. As shown in the figure, the cartridge 1 for a smoking article according to the first embodiment includes a heated body 20 and a support member 3. The heated body 20, the support member 30, and the mouthpiece 40. The heated object 20, the support member 30, and the mouse are arranged side by side on the central axis C1. The pieces 40 are wrapped and integrated with the sheet-like exterior member 10. 0 consists of paper, for example.
[0012] Here, the cartridge 1 for a smoking article shown in FIG. 1 has a diameter of, for example, 6.5 to 7.5 mm. The length is formed to be 40 to 60 mm. The heated body 20 has a length of 10 to 25 mm. Of course, the cartridge 1 for a smoking article may be formed to have other dimensions.
[0013] The heated body 20 is disposed inside the exterior member 10 and has one end facing the support member 30. The cylindrical cavity extends from one end to the other end that is inserted into the heated smoking device 70 described later. The "outer diameter of the heated body" in the present invention is the diameter of this cylinder. In this embodiment, the heated body 20 (aerosol-forming substrate 23) is directly covered by the exterior member 10 (see FIG. 1), and the outside of the heated body 20 The diameter D is the outer diameter of this cylindrical space and is equal to the inner diameter of the exterior member 10. The outer diameter D is generally constant along the central axis C1.
[0014] The heated object 20 includes an aerosol-forming substrate 23 that generates an aerosol when heated. The object to be heated 20 includes the aerosol-forming substrate 23 in any form. The aerosol-forming substrate 23 may be in the form of a strip, a rod, a granule, or the like, as described below. A form filled with a high or low density, multiple strips, rods, granules, etc., filling a specified gap and a form consisting of multiple capsules containing flavor additives. Of course, the aerosol-forming substrate 23 may be in the form of the aerosol-forming substrate 23 described below, which is not listed above. is also good.
[0015] The aerosol-forming substrate 23 contained in the heated body 20 is Even if the filling state inside the exterior member 10 changes depending on the orientation, the outer diameter of the heated body 20 The size of D is always constant, and in the case of this embodiment, the inner diameter of the exterior member 10 is is equal to the size.
[0016] In the above, the heated body 20 (the aerosol-forming substrate 23) is directly exposed to the exterior member 10. However, the case where the heated body 20 is covered with the aerosol-forming substrate 23 will be described later. In the case where the heated body 20 is wrapped in a sheet-like packaging material, the outer diameter D of the heated body 20 is is equal to the outer diameter of the packaging material. When the sol-forming substrate 23 is packed in the packaging material at a low density, the aerosol-forming substrate 23 may move inside the packaging material, but the shape of the packaging material itself remains unchanged. Therefore, the outer diameter D of the object to be heated 20 also remains unchanged.
[0017] Furthermore, the support member 30 is configured to have a packing density of the aerosol-forming base material 23 constituting the heated body 20. Regardless of the above, as long as it has the function of preventing the movement of the heated body 20, the "support member" of the present invention can be used as the "support member" of the present invention. That is, the above-mentioned configurations of the heated body 20 and the supporting member 30 are included in the present invention. For example, the heated body 20 may be a strip, rod, grain, or granular member. When the aerosol-forming substrate 23 is filled at a low density, the smoker may The needle-shaped or blade-shaped heating portion 75 of 0 is inserted into the aerosol-forming substrate 23, Even if the aerosol-forming substrate 23 is pushed toward the support member 30, the aerosol-forming substrate 23 is held in place by the support member 30. Therefore, the movement of the sol-forming substrate 23 toward the support member 30 can be prevented.
[0018] The aerosol-forming substrate 23 is wrapped in an exterior member 10 to form a cylindrical shape. The outer diameter D of the sol-forming substrate 23 is equal to the outer diameter D of the object to be heated 20, and the outer diameter D of the object to be heated 20 is The outer diameter D is approximately constant, for example, between 4.0 mm and 7.5 mm. The outer diameter D is preferably in the range of 5.0 mm to 7.0 mm, and more preferably in the range of 5.0 mm to 7.0 mm. If the nozzle depth is set to 4.0 mm or more, the minimum required amount of aerosol can be generated. If the outer diameter D is set to 5.0 mm or more, a sufficient amount of aerosol can be generated. Furthermore, if the outer diameter D is set to 7.5 mm or less, the heated object 20 can be easily attached to the smoking accessory 70. In addition, if the outer diameter D is set to 7.0 mm or less, the smoking accessory 70 can be attached. The object to be heated 20 can be easily attached.
[0019] In addition, both ends of the aerosol-forming substrate 23 are not covered with a cover member (e.g., paper). One end 23a of both ends of the aerosol-forming substrate 23 is exposed. 30, and the other end 23b is the side to be inserted into the insertion portion 72 of the smoking accessory 70. Here, the term "end" in this specification refers to the end face and a certain area along the central axis C1 from the end face. The heated body 20 includes the aerosol-forming substrate 23, for example. The aerosol-forming substrate may be wound in a sheet-like packaging material made of paper. 23 may be covered with a lid member.
[0020] The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant, which will be described later in detail. The aerosol-forming substrate 23 is, for example, a bundle of rectangular members. The rotor 11 is configured as a rotor 12 and is disposed so that its axial direction (longitudinal direction) is aligned with the central axis C1.
[0021] When the aerosol-forming substrate 23 is formed of a strip-shaped member, the cross section perpendicular to the central axis C1 is approximately It has a rectangular shape, and the ratio of the long side to the short side of the cross section is, for example, in the range of 1:1 to 30:1. The length of the long side is preferably in the range of 0.1 mm to 7.5 mm, and more preferably The length of the short side is preferably in the range of 0.1 mm to 3.0 mm. The range is preferably 0.1 mm to 0.5 mm, and more preferably 0.1 mm to 0.5 mm. It is preferable that the length of the aerosol forming substrate 23 is approximately the same as the length of the object to be heated 20. The length of the hole-forming substrate is preferably in the range of 10 mm to 25 mm, and more preferably in the range of 10 mm to An example of the dimensions of the aerosol-forming substrate 23 is a length of Its sides are 1.5 mm, its short sides are 0.3 mm, and its length is 12 mm.
[0022] Of course, the aerosol-forming substrate 23 is not limited to a strip-shaped member. For example, a rod-shaped member Alternatively, the material may be in the form of powder or paste. The forming base material 23 may be a combination of strip-shaped members and powder-shaped members, or a combination of strip-shaped members and rod-shaped members. combination of rod-shaped and powder-shaped materials, or combination of strip-shaped and rod-shaped materials. It may be a combination of a solid material and a granular material. Using at least a portion of the raw materials different from the others is preferable because it improves the aroma and flavor.
[0023] The mouthpiece 40 is a part that constitutes the mouth of the cartridge 1 for a smoking article, and is made of, for example, paper. The mouthpiece 40 is formed using a material having a diameter of, for example, 6.5 mm to 7.5 mm. The length of the mouthpiece 40 along the central axis C1 is 50 mm or less. For example, a sheet-like member made of paper may be rolled up to form a cylindrical shape, or a The water generated in the heated body 20 may include a cellulose acetate filter or the like. Some of the particles in the vapor or aerosol are filtered out by the filter in the mouthpiece 40. can be.
[0024] The support member 30 is formed by rolling a sheet-like member 31 made of paper once or multiple times into a cylindrical shape. The support member 30 is formed on the aerosol-forming substrate 10 such that its axial direction is aligned with the central axis C1. The support member 30 is disposed between the support member 23 and the mouthpiece 40. The support member 30 is, for example, The length along the support member 30 is 50 mm or less. The first end 30a is a side facing one end 23a of the aerosol-forming substrate 23, and the other end The second end 30b is the end opposite to the first end 30a, i.e., the end opposite to the mouthpiece 40. The first end 30a of the support member 30 is in contact with the aerosol-forming substrate 23, The second end 30b abuts against the mouthpiece 40. Then, the inside of the support member 30 is filled with aerosols. The rule passes through.
[0025] The support member 30 has a truncated cone-shaped through hole 31a therein for allowing the aerosol to pass therethrough, The shape of the first end 30a is different from the shape of the second end 30b. The sheet-like member 31 constituting the 30 is arranged so that the diameter of the second end 30b is smaller than that of the first end 30a. By winding the wire so that the inner diameter r1 of the first end 30a is smaller than the inner diameter r2 of the second end 30b, The inner diameter of the support member 30 is larger than that of the first end 30a to the second end 30b. The width of the first end 30a of the support member 30 is gradually reduced toward the outer periphery of the first end 30a. The diameter R1 is greater than the outer diameter R2 of the second end 30b.
[0026] The size of the inner diameter r1 of the support member 30 is preferably in the range of, for example, 0.5 mm to 6.5 mm. More preferably, the inner diameter r1 is in the range of 0.5 mm to 5.0 mm. m or more, the minimum required for the aerosol to flow through the through-hole 31a of the support member 30. In addition, by setting the inner diameter r1 to 1.0 mm or more, In this case, the size of the flow path is ensured to be large enough for the aerosol to flow through the through hole 31a of the support member 30. Furthermore, if the size of the inner diameter r1 is set to 6.5 mm or less, the heated body 20 In order to support the support member 30, the minimum thickness required can be ensured. If the size is set to 5.0 mm or less, the support member 3 is sufficient to support the heated object 20. It is possible to ensure a thickness of 0.
[0027] The size of the inner diameter r2 of the support member 30 is preferably in the range of, for example, 0.5 mm to 6.5 mm. The inner diameter r2 is preferably in the range of 0.5 mm to 4.5 mm. If the thickness is set to 0.5 mm or more, the aerosol will flow through the through holes 31a of the support member 30 at a maximum. The minimum required flow path size can be secured. Furthermore, the size of the inner diameter r2 is set to 6.5 mm or less. , the minimum thickness of the support member 30 required to support the object to be heated 20 can be ensured. In addition, if the size of the inner diameter r2 is set to 4.5 mm or less, the heated object 20 can be supported. Therefore, it is possible to ensure a sufficient thickness of the support member 30 for this purpose.
[0028] When manufacturing the support member 30, the size of the inner diameters r1 and r2 is appropriately selected within the above range. The size of the flow passage of the support member 30 is adjusted to transfer the aerosol to the mouthpiece 40. In addition, the support member 30 can secure a path for the heated body 20 (aerosol-forming substrate 23). The support strength can be adjusted to appropriately support the heated body 20 depending on the material of the aerosol-forming substrate 23. Cut.
[0029] The length of the support member 30 along the central axis C1 and the inner diameters r1 and r2 are set to the aerosol forming By appropriately selecting within the above range according to the shape of the base material 23, the outer periphery of the support member 30 The inclination angle is adjusted to prevent the aerosol-forming substrate 23 from moving toward the mouthpiece 40. For example, the aerosol-forming substrate 23 may be in the form of a powder, grain, or granule (e.g., a capsule). In this case, the length of the support member 30 is set to be short, and the size of the inner diameter r1 is set to be larger than the size of the inner diameter r2. If the size is set sufficiently larger than the size of the first end 30a of the outer periphery of the support member 30, the inclination The angle can be set small. At this time, the outer periphery of the support member 30 is the first end 30a. From the first end 30b to the second end 30b, the aerosol-forming substrate 23 is inclined downward. Even if the aerosol-forming substrate 23 enters the through-hole 31a of the support member 30, the aerosol-forming substrate 23 is The support member 30 comes into contact with the outer periphery of the mouthpiece 40 and cannot move toward the mouthpiece 40. The aerosol-forming substrate 23 can be prevented from moving toward the mouthpiece 40 within the through-hole 31a. In addition, the inner diameter r1 of the support member 30 is made small so that the distance between the inner diameter r1 and the outer diameter R1 of the support member 30 is If the aerosol-forming substrate 23 can be sufficiently supported by the thickness of the inner diameter r Regardless of 2, the aerosol-forming substrate 23 enters the through-hole 31a of the support member 30. becomes difficult.
[0030] The outer diameter R1 of the support member 30 is preferably in the range of, for example, 4.0 mm to 7.5 mm. More preferably, the outer diameter R of the support member 30 is in the range of 5.0 mm to 7.0 mm. The size of 2 is preferably in the range of, for example, 1.0 mm to 7.5 mm, and more preferably 1. The size of the outer diameter R1 is in the range of 5 mm to 6.5 mm. In other words, it is preferable to set the outer diameter R1 and the outer diameter It is preferable that the dimension of D is the same as that of the aerosol-forming substrate 23. The moving member 10 moves toward the supporting member 30 through the gap between the first end 30a of the supporting member 30 and the exterior member 10. This can prevent the following:
[0031] Next, referring to FIG. 2, the outer diameter R1 and the inner diameter r1 of the support member 30 and the aerosol-forming group The relationship between the outer diameter D of the material 23 and the thickness of the material 23 will be described. The left side of FIG. 2 shows the smoking article cover shown in FIG. A cross section of the cartridge 1 taken along line II-II, viewed from the support member 30 side. 2 is a longitudinal cross-section of the aerosol-forming substrate 23, and the right side of FIG. 2 is a longitudinal cross-section of the aerosol-forming substrate 23. 1 is a vertical cross section of the support member 30 as seen from the front.
[0032] In FIG. 2, L1 passes through the top of the aerosol-forming substrate 23 and the support member 30. L2 is a straight line passing through the top of the inner periphery of the support member 30 (sheet-like member 31), and L3 is a straight line passing through the inner periphery of the support member 30 (sheet-like member 31). A straight line L4 passing through the bottom of the inner circumferential portion of the support member 30 is a straight line L4 passing through the aerosol-forming substrate 23 and the support member It is a straight line passing through the bottom of 30.
[0033] The outer diameter R1 of the support member 30 is set to be equal to the outer diameter D of the aerosol-forming substrate 23. As shown in FIG. 2, the outer diameter R1 of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 are both Therefore, the first end 30a of the support member 30 corresponds to the length between L1 and L4. The outer peripheral portion of one end portion 23a of the aerosol forming substrate 23 can be supported. If the first end 30a of the member 30 can support the outer periphery of the aerosol-forming substrate 23, the outer diameter R 1 may be smaller than the outer diameter D.
[0034] The inner diameter r1 of the support member 30 corresponds to the length between L2 and L3. The inner diameter r1 of the support member 30 is smaller than the outer diameter D of the base material 23. The length (Δr) between the outer diameter R1 (≦outer diameter D) and between L1 and L2 and between L3 and L4 Length (Δr), that is, the length excluding the thickness (2Δr) of the support member 30 (sheet-like member 31) Therefore, the first end 30a of the support member 30 corresponds to the thickness portion of the sheet-like member 31. This allows the aerosol-forming substrate 23 to be supported from its outer periphery to a portion inside the predetermined range.
[0035] The magnitude of the above Δr is preferably in the range of, for example, 0.5 mm to 3.5 mm, and more preferably The range is preferably 1.0 mm to 3.25 mm. The magnitude of Δr is set to 0.5 mm or more. This makes it possible to ensure the minimum thickness of the support member 30 required to support the object to be heated 20. In addition, if the magnitude of Δr is set to 1.0 mm or more, the heating target 20 can be supported. It is possible to ensure a sufficient thickness of the support member 30. Furthermore, the magnitude of Δr is set to 3.5 mm or less. If set, the minimum flow path required for the aerosol to flow through the through hole 31a of the support member 30 is In addition, if the size of Δr is set to 3.25 mm or less, the air Therefore, a flow path of sufficient size can be secured so that the sol can flow through the through hole 31a of the support member 30. do.
[0036] In this way, the outer diameter R1 and the inner diameter r1 of the support member 30 are equal to the outer diameter D Since the support member 30 has the above-mentioned relationship with respect to the outer periphery of the aerosol-forming substrate 23, It is possible to support not only the outer peripheral portion but also the portion within a specified range.
[0037] In FIG. 1, the inner diameter r1 of the support member 30 is larger than the inner diameter r2. The aerosol is not limited to the above-mentioned configuration. If one end 23a of the forming base 23 can be supported, the inner diameter r2 of the supporting member 30 is The inner diameter r2 of the support member 30 may be equal to or greater than the inner diameter r1. When the inner diameter of the support member 30 is equal to the first end 30a to the second end 30b, In addition, when the inner diameter r2 of the support member 30 is larger than the inner diameter r1, The inner diameter of the support member may increase from the first end 30a to the second end 30b. Alternatively, the width may gradually increase from the first end 30a to the second end 30b. When the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and when it is larger than the inner diameter r1, In either case, the outer diameter R1 and the outer diameter R2 of the support member 30 may be made equal.
[0038] The support member 30 is configured so that various fillers can be filled into the through holes 31a. Such a filler may be, for example, a granular material, a fibrous material, a porous material, or Flavor additives and the like.
[0039] When granular materials are used, for example, plastic particles can be used. The shape of the granular materials is particularly However, the cross-sectional shape is not limited to the above, and may be, for example, a circle, an ellipse, a polygon, or the like. It may be solid or hollow, and its particle size is preferably, for example, 0.5 mm to 1 mm.
[0040] When filled with fibrous materials, for example cellulose acetate (CA) fibers or polyethylene A polyester fiber body such as terephthalate (PET) can be used.
[0041] When porous materials are used, for example, polyolefin resins such as PE and PP, and PET resins , CA resin, polylactic acid (PLA), metal foil such as aluminum, and metal itself are used. can.
[0042] Furthermore, when the above-mentioned granular materials are filled, the filling material may be mixed into the aerosol. Activated carbon, which can remove certain chemicals (such as tar) that have been absorbed, and ceramics and glass, etc. Particles made of inorganic materials such as those mentioned above may be used, and a mixture of these types of particles may be used. In addition, the above-mentioned chemical substances (e.g., formaldehyde) may be used in part or all of the filling material. A remover (e.g., chitosan) capable of removing aldehydes such as aldehyde may be added.
[0043] Alternatively, when the above-mentioned granular material is filled, the filling material is a material for extracting coffee. Alternatively, plant-based raw materials such as coffee grounds after brewing or used tea leaves after tea leaves are extracted may be used. These plant-based materials are porous and have a high deodorizing effect, so they are used as support parts with deodorizing effect. In addition, when using coffee grounds, the coffee grounds can be used as is. Because the particle size is small, it is recommended to use it in a ball-like form using starch or other materials. When using tea leaves, if the aerosol-forming substrate 23 is made of tea leaves, Both 23 and support member 30 can be made of the same material.
[0044] When flavor additives are added, for example, mint, cocoa, coffee, black tea extract, tea extract, etc. The flavor additive can be filled into the through hole 31a of the support member 30. The filling mode may be any of various modes as described below.
[0045] For example, when the flavor additive is enclosed in a capsule, the capsule is inserted into the through hole 31a. This allows smokers to press the capsule with their fingers to destroy it. This allows the flavor additive's aromatic components to volatilize at the desired timing. If the capsule has melting properties, it will melt when exposed to an aerosol and add flavor. Furthermore, when the capsule is a microcapsule, the microcapsule can be released to the outside. The microcapsules may be embedded in the inner circumferential surface of the support member 30. The flavor additive may be disposed in the through hole 31a. In addition, when the flavor additive is not encapsulated, For example, a flavor additive may be impregnated into the inner circumferential surface of the support member 30 .
[0046] Next, specific examples of the raw material used as the aerosol-forming substrate 23 will be described. The sol-forming substrate 23 is composed of any one or a combination of the following raw materials: will be done.
[0047] The aerosol-forming substrate 23 is made from a tobacco plant or a non-tobacco plant.

It is obtained by partially depolymerizing α-cellulose obtained from pulp with acid. It is obtained by removing the soluble portion from cellulose and, if necessary, crystallizing the insoluble portion. .
[0054] The microcrystalline cellulose may be in the form of a powder or may be dispersed in a solvent such as water to form a suspension. In this case, a high-speed stirrer or a high-pressure homogenizer can be used for dispersion in the solvent.
[0055] Furthermore, if necessary, a flavor additive may be used as a raw material for the aerosol-forming base material 23 to add flavor.

[0056] The aerosol-forming substrate 23 contains menthol and a water-insoluble crosslinked polymer (preferably poly Vinyl polypyrrolidone) may be included. By combining these two ingredients, it is possible to effectively suppress the sublimation of menthol and maintain the menthol flavor for a long period of time. Here, menthol is not limited to that obtained from natural products, but may be a synthetic product. You can also use peppermint, mint, peppermint oil, or other menthol-containing products. good.
[0057] The flavor additive may be added to the mouthpiece 40, for example, by impregnating the walls of the mouthpiece 40. The embodiment in which the flavor additive is provided in the mouthpiece 40 is The present invention is not limited to such an embodiment, and may be embodied, for example, in the form of a capsule containing the flavor additive. The flavor additive is provided in the mouthpiece 40 by embedding it in the wall of the mouthpiece 40.

[0060] (Method of manufacturing an aerosol-forming substrate) The above-mentioned method for producing the aerosol-forming substrate 23 will be described in detail below. The manufacturing process of the sol-forming substrate 23 is as follows: the main raw material, tobacco plants or non-tobacco plants, are dried and powdered. The drying and grinding process involves crushing, weighing, etc., and the preparation process involves pre-processing and weighing of other raw materials. The method includes a mixing step of mixing the raw materials to form a composition, and a filling molding step of molding the composition. do.
[0061] In the drying and grinding process, the main raw material, tobacco plant or non-tobacco plant parts (e.g. In order to make a composition, the following materials (e.g., leaves, seeds, dried fruits, stems, bark, roots, etc.) are processed into a specified crushed material. At that time, the aerosol former, water, and other components that are added later are absorbed or supported. It is preferable to adjust the moisture content to a level suitable for drying. By setting the temperature in this range, it is possible to prevent the necessary flavor components from scattering while obtaining the desired flavor. It is easy to achieve the desired moisture content. In addition, the drying and crushing process includes a sieving process to sift the crushed material. It is also possible to provide a powder having a desired particle size and then introduce the powder into the mixing step.
[0062] In the preparation step, raw materials necessary for producing the aerosol-forming substrate 23 are prepared. The microcrystalline cellulose can be weighed in the preparation step and then mixed in the mixing step. It is entered.
[0063] In the mixing step, a conventional mixer can be used. For example, A mixing mode in which the ingredients are mixed while applying shear force with a stirring blade is preferably used.
[0064] In the filling molding process, the composition in which various raw materials are mixed is formed into a thin sheet and then cut. By cutting, a strip-shaped or rod-shaped aerosol-forming substrate 23 is formed. In order to make a thin sheet, multiple roll mills are used. When the material is pressed between the narrow rolls, it is compressed and sheared by the difference in roll speed. While kneading and dispersing, the material can be formed into a sheet of the desired thickness using a doctor blade. It is possible and preferable to use a press roller or a press machine. Cut.
[0065] In order to prepare the powdered or granular aerosol-forming base material 23, the above composition is appropriately It is preferable to crush or classify the powder or granular aerosol-forming base material 23. The average particle size is preferably, for example, 0.1 to 3.0 mm, and is preferably 0.5 mm or less. It is more preferable that the average particle size is, for example, In other words, this average particle size is determined by the sieving method described in Regarding the test results, the mass of the larger opening was calculated and 50% of that mass was used. The diameter is the cumulative value of 50 in the particle size distribution obtained by the laser diffraction / scattering method. The particle size in % may be taken as the average particle size.
[0066] In the filling molding process, the composition is forced through an orifice under pressure to form a shape similar to other processes. In the filling forming step, a non-tobacco plant, an aerobic plant, etc. may be used as necessary. Solformers, binders or thickeners, flavor additives, and preservatives may be further added. Water or the like may be added.
[0067] The thickness of the sheet obtained in the filling molding step is preferably in the range of 0.1 mm to 1.0 mm. The thickness of the obtained sheet is preferably in the range of 0.1 mm to 0.5 mm. The sheet is then cut to a specified width using a rotary cutter or the like.
[0068] Here, in the case where the surface of the aerosol-forming substrate 23 is to be made adhesive, There is no particular limitation as long as the means is such that the binder described above is adhered to at least a part of the surface. By imparting adhesiveness, the aerosol-forming substrate 23 in the form of a strip or rod and the powder, granules, or When combined with the aerosol-forming base material 23 in the form of a strip or rod, The aerosol-forming substrate 23 is applied on the surface of the aerosol-forming substrate 23 in the form of a powder, granules or paste. It can be held stable.
[0069] (How to use smoking cartridges) A method of using the cartridge 1 for smoking articles will be described. FIG. 3 shows the cartridge 1 for smoking articles. 1 is a cross-sectional view of the cartridge 1 inserted into a smoking article 70. The smoking article 70 is used by being attached to the smoking article cartridge 1. The insertion part 72 is provided with a needle-shaped or blade-shaped heating part 75. When the cartridge 1 for a smoking article is inserted into the insertion portion 72, the heating portion 75 generates heat. In this state, the smoker When the person holds the mouthpiece 40 in his / her mouth and inhales, the aerosol enters the through holes 31 a of the support member 30, The air flows through the mouthpiece 40 and into the smoker's mouth.
[0070] The cartridge 1 for a smoking article according to the first embodiment configured as above has the following advantages: It can produce results.
[0071] Since the inner diameter r1 of the support member 30 is smaller than the outer diameter D of the aerosol-forming substrate 23, The thickness of the member 30 between the inner diameter r1 and the outer diameter R1 of the member 30 is such that the heated object 20 (aerosol type Therefore, the support of the heated body 20 (aerosol-forming substrate 23) can be achieved. Movement toward the support member 30 can be suppressed.
[0072] In addition, the outer diameter R1 of the support member 30 and the size of the heated body 20 (aerosol-forming substrate 23) The outer diameter D of the support member 30 can be set to be the same as the outer diameter D of the support member 30. The entire end portion 30a can be in contact with the aerosol-forming substrate 23. Since the aerosol-forming substrate 23 can be sufficiently supported by the heating member 20 (the aerosol-forming substrate 23), 23) can be further suppressed from moving toward the support member 30. 3, the first end 30a of the support member 30 passes between the exterior member 10 and the first end 30a of the support member 30. This can prevent this from happening.
[0073] In addition, since the shape of the first end 30a of the support member 30 is different from the shape of the second end 30b, The shape of the through hole 31a of the support member 30 is not uniform along the central axis C1. Even if a part of the aerosol-forming substrate 23 enters the through-hole 31a, it does not move inside the through-hole 31a. It is difficult to do so.
[0074] Furthermore, the inner diameter r1 of the support member 30 is larger than the inner diameter r2, and the through hole 3 of the support member 30 The diameter of the through hole 31a is smaller at the second end 30b than at the first end 30a. This makes it even more difficult for the aerosol-forming substrate 23 that has entered inside a to move.
[0075] In addition, the support member 30 is gradually inwardly inward from the first end 30a to the second end 30b. Since the diameter is small, the aerosol that enters the through hole 31a of the support member 30 is The aerosol forming substrate 23 and the inner periphery of the through hole 31a collide with each other. Therefore, the space for the hole-forming substrate 23 to escape is restricted. Therefore, the movement of the sol-forming substrate 23 can be prevented.
[0076] In addition, since the support member 30 is formed by rolling up the sheet-like member 31, the aerosol-forming base material Friction is likely to occur between the through hole 31 of the support member 30 and the sheet-like member 31. The movement of the aerosol-forming substrate 23 that has entered the space a can be further prevented.
[0077] Furthermore, the support member 30 has a simple structure in which the sheet-like member 31 is rolled into a cylindrical shape, and therefore is easy to manufacture. This reduces manufacturing costs.
[0078] Second embodiment Next, a cartridge for a smoking article according to a second embodiment will be described. The cartridge 2 for a smoking article is basically the same as the cartridge 1 for a smoking article according to the first embodiment. Although the configuration is the same, the difference is that the support member 30 is made of a resin molded product 32 in a truncated cone shape. Therefore, in the following description, the differences will be mainly described, and descriptions that overlap with the first embodiment will be omitted. do.
[0079] FIG. 4 is a cross-sectional view of a cartridge 2 for a smoking article according to the second embodiment. As shown in FIG. The support member 30 (resin molded product 32) has its lower bottom surface facing the aerosol-forming substrate 23. The first end of the support member 30 is disposed so that its upper and bottom surfaces face the mouthpiece 40. The shape of the first end 30a is different from the shape of the second end 30b. The support member 30 has a through hole 32a having a shape similar to that of the support member 30, and the inner diameter r1 of the support member 30 is larger than the inner diameter r2. The outer diameter R1 of the first end 30a of the support member 30 is larger than the outer diameter R2 of the second end 30b. Furthermore, a plurality of recesses 32c are formed on the outer peripheral surface 32b of the support member 30. Instead of the recess 32c, a plurality of protrusions may be formed.
[0080] Next, referring to FIG. 5, the outer diameter R1 and the inner diameter r1 of the support member 30 and the aerosol-forming group The relationship between the outer diameter D of the material 23 and the smoking article cover shown in FIG. Aerosol formation in a cross section of the cartridge 2 cut along line VV as viewed from the support member 30 side. 5 is a longitudinal cross section of the substrate 23, and the right side of FIG. 5 is a cross section viewed from the aerosol-forming substrate 23 side. 1 is a vertical cross section of the support member 30.
[0081] As shown in FIG. 5, the outer diameter R1 of the support member 30 (resin molded product 32) and the aerosol formation The outer diameter D of the base material 23 corresponds to the length between L1 and L4. The inner diameter r1 is the length between L2 and L3, that is, the outer diameter R1 (=outer diameter D) of the support member 30. This corresponds to the length excluding the thickness (2Δr) of the thick portion of the support member 30.
[0082] According to the cartridge 2 for a smoking article according to the second embodiment configured in this manner, The same effects as those of the first embodiment can be obtained. Since the outer diameter R1 of the member 30 is larger than the outer diameter R2, the support member 30 has a large aerodynamic area. The support member 30 can contact one end 23a of the sol-forming substrate 23. Since the aerosol-forming base 23 is made of a plastic molded product 32, the thick part of the plastic molded product 32 is 23a can be reliably supported, and the heated body 20 (aerosol-forming substrate 23) can be moved toward the support member 30 side. The movement of the material can be reliably suppressed.
[0083] In addition, since a plurality of recesses 32c are formed on the outer peripheral surface 32b of the support member 30, When manufacturing the cartridge 2, the support member 30 can be easily gripped, and the manufacturing efficiency can be improved. Of course, instead of the multiple recesses 32c, multiple protrusions may be formed. It has the same effect.
[0084] In FIG. 4, the inner diameter r1 of the support member 30 is larger than the inner diameter r2. The aerosol type is not limited to the above-mentioned configuration. If one end 23a of the substrate 23 can be supported, the inner diameter r2 of the support member 30 is equal to the inner diameter r1. The inner diameter r2 of the support member 30 may be equal to or greater than the inner diameter r1. If they are equal, the inner diameter of the support member 30 will be uniform from the first end 30a to the second end 30b. In addition, when the inner diameter r2 of the support member 30 is larger than the inner diameter r1, The inner diameter of the support member 30 increases from the first end 30a to the second end 30b. Alternatively, the width may gradually increase from the first end 30a to the second end 30b. In the case where the inner diameter r2 of the support member 30 is equal to the inner diameter r1 and is larger than the inner diameter r1, In either case, the outer diameter R1 and the outer diameter R2 of the support member 30 may be made equal.
[0085] Third embodiment Next, a cartridge for a smoking article according to a third embodiment will be described. The cartridge 3 for a smoking article is a support member made of a cylindrical body formed by rolling up a sheet-like member 33. The member 30 has a plurality of (four in this embodiment) protrusions 33b on its inner circumferential surface 33a. This is different from the first embodiment.
[0086] The four protrusions 33b are each formed on a part (four locations) of the outer circumferential surface 33c of the sheet-like member 33. A cut is made in the sheet at an angle to the longitudinal direction, and the part where the cut is made is folded inward. The four protrusions 33b extend along the central axis C1 and are formed by bending the support member 30. The protrusions 33b are arranged at equal intervals (90 degree intervals) in the circumferential direction (see FIG. 7 described later). The width W1 of the support member 30 on the first end 30a side is narrower than the width W2 on the second end 30b side. The width of each protrusion 33b is set to be 1 / 2 mm from the first end 30a of the support member 30 to the second end 30a of the support member 30. The width of the first end 30b of the support member 30 is gradually increased. The shape of a is different from the shape of the second end 30b.
[0087] The width W1 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm. More preferably, the width W1 is in the range of 1.0 mm to 3.0 mm. If the width is set to the upper side, the minimum width of the support member 30 required to support the object to be heated 20 can be secured. In addition, if the width W1 is set to 1.0 mm or more, the object to be heated 20 can be supported. In addition, the width W1 of the support member 30 can be set to 4.0 mm. m or less, the aerosol will flow through the area within circle C shown by the dotted line in Figure 7. The required flow path size can be secured. In addition, the width W1 is set to 3.0 mm or less. Then, the flow path is large enough for the aerosol to flow through the area within the dotted circle C in Figure 7. It is possible to ensure the reliability.
[0088] The width W2 of the support member 30 is preferably in the range of, for example, 0.5 mm to 4.0 mm. The width W2 is preferably in the range of 0.25 mm to 3.25 mm. If the thickness is set to 0.5 mm or more, the minimum required support member 30 for supporting the heated object 20 is In addition, if the width W2 is set to 1.25 mm or more, the heated object It is possible to ensure a sufficient width of the support member 30 to support the support member 20. Furthermore, the width W2 is large. If the thickness is set to 4.0 mm or less, the aerosol will flow within the area indicated by the dotted line in circle C' in Figure 7. In order to achieve this, it is possible to ensure the minimum required flow path size. If the diameter is set to 5 mm or less, the aerosol will flow through the area indicated by the dotted circle C' in Figure 7. Therefore, it is possible to ensure a flow path of sufficient size.
[0089] When manufacturing the support member 30, the widths W1 and W2 are appropriately selected within the above range. In addition, the size of the flow path of the support member 30 can be adjusted. The support strength of the aerosol-forming substrate 23 is adjusted according to the material of the aerosol-forming substrate 23. The object to be heated 20 can be supported appropriately.
[0090] In the following, for the sake of convenience, the four protrusions 33b of the support member 30 (sheet-shaped portion The protrusion 33b formed on the top of the member 33 is called the "first protrusion 331b." The protrusions 33b are formed at positions rotated 90 degrees clockwise from the rib 331b. The second protrusion 332b, the third protrusion 333b, and the fourth protrusion 334 are arranged in this order. "b".
[0091] Next, referring to FIG. 7, the outer diameter R and the inner diameter r1 of the support member 30 and the aerosol-forming substrate The relationship between the outer diameter D of 23 and the smoking article cartridge shown in FIG. FIG. 7 is a cross section of the cartridge 3 taken along line VII-VII, viewed from the support member 30 side. 7 is a vertical cross section of the aerosol-forming substrate 23, and the right side of FIG. 7 is a vertical cross section of the aerosol-forming substrate 23. 7 is a vertical cross-sectional view of the support member 30 as viewed from the front. L2 is a straight line passing through the tip of the first protrusion 331b at the first end 30a, and L3 is a straight line passing through the tip of the third protrusion In the right diagram of FIG. 7, a dotted circle C is a straight line passing through the tip of the first portion 33b. The first to fourth protrusions 331b to 334b are connected at their tips in an arc shape, and the diameter of the arc is The inner radius r1 of the member 30 is shown.
[0092] As shown in FIG. 7, the outer diameter R of the support member 30 (sheet-shaped member 33) and the aerosol formation The outer diameter D of the base material 23 corresponds to the length between L1 and L4. The inner diameter r1 is the length between L2 and L3, which corresponds to the diameter of the circle C, that is, the outer diameter of the support member 30. R (=outer diameter D) to the width (W1) of the first protrusion 331b and the width (W 7, the right side of each protrusion 33b corresponds to the value excluding 1). The part of the support member 30 that protrudes inward is directed from the first end 30a to the second end 30b. This is the part that used to be wide.
[0093] According to the cartridge 3 for a smoking article according to the third embodiment configured in this manner, The same effects as those of the first embodiment can be obtained. The member 30 has a plurality of protrusions 33b extending along the central axis C1 on its inner peripheral surface 33a. Therefore, the aerosol-forming substrate 23 can be firmly supported on the first end portion 30a side of the supporting member 30. In addition, since the four protrusions 33b are arranged at equal intervals in the circumferential direction of the support member 30, The aerosol-forming substrate 23 can be supported in a well-balanced manner.
[0094] The support member 30 is formed by rolling up a sheet-like member 33, and has a plurality of protrusions 33b. are formed by bending a part of the outer circumferential surface 33c of the sheet-like member 33 inward. Therefore, the support member 30 can have a simple structure, and the manufacturing cost can be reduced.
[0095] The support member 30 may be made of a resin molded product as in the second embodiment. In this case, the plurality of protrusions are formed by resin molding so as to protrude from the inner peripheral surface of the support member 30. In addition, the number of the plurality of protruding portions 33b is not limited to four, and may be one or more. That's good.
[0096] In FIG. 6, the width W1 of the support member 30 is narrower than the width W2. However, the present invention is not limited to this configuration. If one end 23a of the substrate 23 can be supported, the width W2 of the support member 30 is equal to the width W1. When the width W2 of the support member 30 is equal to the width W1, The width of the support member 30 from the first end 30a to the second end 30b is The width W2 of the support member 30 may be uniform toward the end portion 30b. When the width W1 is larger than the width W2, the width from the first end 30a to the second end 30b of the support member 30 is The thickness may increase from the first end 30a to the second end 30b, or may increase from the first end 30a to the second end 30b. It may gradually increase from 0a toward the second end 30b.
[0097] (Fourth embodiment) Next, a cartridge for a smoking article according to a fourth embodiment will be described. The cartridge 4 for a smoking article has a heated body 20 (aerosol) attached to a first end 30a of a support member 30. The first embodiment is different from the first embodiment in that a blocking portion 34 is formed to block the axial movement of the hole forming base material 23. is different.
[0098] The blocking portion 34 protrudes from the inner peripheral surface of the first end portion 30a of the support member 30 toward the central axis C1. The support member 30 is made up of a plurality of (six in this embodiment) protrusions 34a. The six protrusions 34a are arranged along the cylindrical portion 35. The protrusions 34a are provided on the substrate 23 side. The support members 3a and 3b are arranged at equal intervals (60 degree intervals) in the circumferential direction so as to face each other. The shape of the first end 30a of the 0 is different from the shape of the second end 30b.
[0099] In the following, for convenience of explanation, only one of the six protruding portions 34a of the support member 30 (cylindrical portion 35 The protrusion 34a formed on the top of the first protrusion 341a is called the "first protrusion 341a".

In FIG. 9, L2 is a first projection of the support member 30. L2 is a straight line passing through the tip of the fourth protrusion 344a of the support member 30. In the right diagram of FIG. 9, a dotted circle C' is a straight line passing through the tip of the first to sixth The tip ends of the protrusions 341a to 346a are connected in an arc shape, and the diameter of the arc is equal to the diameter of the support member 30. The size of this inner diameter r1 is, for example, 6.5 mm or less.
[0101] As shown in FIG. 9, the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 are The inner diameter r1 of the support member 30 corresponds to the length between L1 and L4. The length between L2 and L3, which corresponds to the diameter, is the outer diameter R (=outer diameter D) of the support member 30. The amount of projection (T) of the first protrusion 341a and the amount of projection (T) of the fourth protrusion 344a The value corresponds to the value excluding the length. The size of the protrusion amount (T) is, for example, 0.5 mm to 3.5 The range of the protrusion is preferably 1.0 mm to 3.25 mm, and more preferably 1.0 mm to 3.25 mm. If the size of the amount (T) is set to 0.5 mm or more, the minimum required amount of heat to support the heated body 20 is It is possible to secure the necessary protrusion amount of the support member 30. In addition, the size of the protrusion amount (T) is set to 1.0 mm. m or more, a sufficient protrusion amount of the support member 30 for supporting the heated object 20 is ensured. Furthermore, if the projection amount (T) is set to 3.5 mm or less, the aerosol The minimum flow path size required for the flow to pass through the area within the dotted circle C' in Figure 9 can be secured. In addition, if the projection amount (T) is set to 3.25 mm or less, the aerosol It is possible to ensure a flow path large enough for the water to flow through the area within circle C' shown by the dotted line in Figure 9. .
[0102] When manufacturing the support member 30, the size of the protrusion amount (T) is appropriately selected within the above range. In addition, the size of the flow passage on the first end 30a side of the support member 30 can be adjusted. The support strength of the heated body 20 (aerosol-forming substrate 23) is adjusted by the The heated object 20 can be appropriately supported depending on the material of 23.
[0103] According to the cartridge 4 for a smoking article according to the fourth embodiment configured in this manner, The fourth embodiment can achieve the same effects as the first embodiment. The first end 30a of the member 30 is provided with a heater 20 (aerosol-forming substrate 23) for axial movement. Since the blocking portion 34 that blocks the movement is formed, the heated body 20 (aerosol-forming substrate 23 ) toward the support member 30 side. Since the portion 34a is provided along the circumferential direction of the support member 30, the outer periphery of the aerosol-forming substrate 23 This allows the peripheral portion and the portion within a predetermined range inside the outer periphery to be reliably supported.

The right side of FIG. 13 shows the same cross section as the aerosol-forming substrate 23. 13 is a vertical cross-sectional view of the support member 30 as viewed from the forming base material 23 side. L1 is a straight line passing through the tip of the first protrusion 361a of the support member 30, and L2 is a straight line passing through the tip of the first protrusion 361a of the support member 30. 5 is a straight line passing through the tip of the protruding portion 365a. Also, in the right diagram of FIG. 13, The circle C' is drawn by connecting the tips of the first to eighth protrusions 361a to 368a in an arc shape. The diameter represents the inner diameter r1 of the support member 30.
[0118] As shown in FIG. 13, the outer diameter R of the support member 30 and the outer diameter D of the aerosol-forming substrate 23 are Both of these correspond to the length between L1 and L4. The inner diameter r1 of the support member 30 is the same as that of the circle C' The length between L2 and L3, which corresponds to the diameter of the support member 30, i.e., the outer diameter R (=outer diameter D) of the support member 30 3 corresponds to the protrusion amount (T) of the first protrusion 361a and the protrusion amount (T) of the fifth protrusion 365a. This corresponds to the value excluding the length of the
[0119] According to the cartridge 6 for a smoking article according to the sixth embodiment configured in this manner, The same effects as those of the first and fourth embodiments can be obtained. According to the embodiment, the plurality of protrusions 36a of the blocking portion 36 have a sawtooth shape, so that even if an aerosol Even if a part of the aerosol-forming substrate 23 enters the inside of the support member 30, the aerosol-forming substrate 23 The heated object is caught by the sharp tips of the protrusions 36a, making it difficult for the object to move. The movement of the body 20 (the aerosol-forming substrate 23) toward the support member 30 can be reliably suppressed.
[0120] In addition, the blocking portion 36 (plurality of protruding portions 36a) is formed only on the first end portion 30a of the support member 30. Therefore, the support member 30 can be made to have a simple structure, and the manufacturing cost can be reduced. .
