Description

[Technical field]

[0001] The present invention relates to flavor generating articles and smoking systems. [Background technology]

[0002] Conventionally, flavor generating articles for inhaling flavors and the like without burning materials are known (for example, Patent Documents 1 and 2). Such flavor generating articles have a flavor source including tobacco containing volatile components, and can be heated directly from inside the flavor source by inserting a heater or the like inside the flavor source. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2020 / 002165 [Patent Document 2] International Publication No. 2020 / 007879 Summary of the Invention [Problem to be solved by the invention]

[0004] A so-called internal heating type heating device, which heats a flavor source from the inside by a heater such as a heating blade, a heating pin, or a susceptor, can directly heat the flavor source to a high temperature. It is required to efficiently heat the flavor source with such an internal heating type heating device.

[0005] SUMMARY OF THE PRESENT EMBODIMENTS It is an object of the present invention to provide a flavor generating article and smoking system that are capable of heating efficiently. [Means for solving the problem]

[0006] According to a first aspect, there is provided a flavor generating article that generates a flavor by heating. The flavor generating article has a through hole into which a heater can be inserted and a cylindrical elastically deformable sheet that defines the through hole. The elastically deformable sheet is elastically deformable in its thickness direction.

[0007] According to the first aspect, when the heater is inserted into the through hole, the elastically deformable sheet elastically deforms in the thickness direction relative to the heater, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet contains a flavor, or when a sheet containing a flavor is present inside the elastically deformable sheet, the sheet containing the flavor can be brought into closer contact or proximity with the heater, so that the flavor-generating product can be heated efficiently.

[0008] A second aspect is summarized in that in the first aspect, the elastically deformable sheet has a volume void ratio of 85% or more and 95% or less.

[0009] According to the second aspect, the flavor-containing sheet can be brought into more appropriate contact or proximity with the heater. If the volume void ratio of the elastically deformable sheet is less than 85%, the elastically deformable sheet has too strong a repulsive force, making it difficult to deform the flavor-generating article. In this case, there is a risk that the airflow resistance of the flavor-generating article will increase too much. If the volume void ratio of the elastically deformable sheet is more than 95%, the elastically deformable sheet has too weak a repulsive force, and when the flavor-generating article is deformed, the contact between the inner wall of the flavor-generating article and the heater will be weak, which may affect delivery.

[0010] A third aspect is characterized in that in the first or second aspect, the elastically deformable sheet has an airflow resistance of 0 mmH2O or more and 150 mmH2O or less.

[0011] According to the third aspect, even if no gap occurs between the heater and the elastically deformable sheet, the airflow resistance during inhalation by the user can be made appropriate. If the airflow resistance of the elastically deformable sheet exceeds 150 mmH2O, the inhalation resistance becomes too high, and the user may feel uncomfortable when inhaling.

[0012] A fourth aspect is any one of the first to third aspects, wherein the elastically deformable sheet has a density of 30 g / m 2 More than 100g / m 2 The present invention relates to a non-tobacco sheet having the following basis weight:

[0013] According to the fourth aspect, the flavor-containing sheet can be brought into more appropriate contact with the heater. 2 If the basis weight is less than 100 g / m, the flavor may be quickly exhausted, or the elastically deformable sheet may be too thin and prone to tearing during the manufacturing process, resulting in poor manufacturability, or the elastically deformable sheet may be torn when the heater is inserted. 2 If it is greater than 100%, it becomes difficult to bend the elastically deformable sheet and to deform the flavor generating article 10. In this case, the heat capacity becomes large, so that the temperature rise of the flavor generating article 10 becomes slow, and it may take a long time before the first puff is possible.

[0014] A fifth aspect is summarized in that in any one of the first to fourth aspects, the elastically deformable sheet is a non-tobacco sheet carrying an aerosol source or a flavor-generating substrate.

[0015] According to the fifth aspect, the elastically deformable sheet is efficiently heated by contacting or approaching the heater, and an aerosol or a flavor can be generated.

[0016] A sixth aspect is summarized in that in any one of the first to fifth aspects, the elastically deformable sheet is a non-tobacco sheet having a corrugated cross section when viewed in the longitudinal direction.

[0017] According to the sixth aspect, the elastically deformable sheet can be elastically deformed in its thickness direction by deforming the corrugated cross section of the non-tobacco sheet. In addition, the non-tobacco sheet with the corrugated cross section has gaps (between the waves) along its longitudinal direction, so that it can define flow paths through which the flavor generated in the flavor generating article passes.

[0018] A seventh aspect is based on any one of the first to sixth aspects, and further comprises a flavor generating sheet located inside the elastically deformable sheet.

[0019] According to the seventh aspect, by bringing the elastically deformable sheet into contact with or close to the heater, the flavor-generating sheet located inside the elastically deformable sheet can be brought into contact with or close to the heater, and the flavor-generating sheet can be efficiently heated to generate an aerosol or flavor.

[0020] An eighth aspect is the seventh aspect, wherein the flavor-generating sheet includes a non-tobacco sheet carrying an aerosol source or a flavor-generating substrate.

[0021] According to the eighth aspect, the aerosol source or flavor-generating substrate of the non-tobacco sheet is efficiently heated, and it is possible to generate an aerosol, a flavor, etc. In this specification, the flavor-generating substrate carried on the non-tobacco sheet may include, for example, tobacco extract, synthetic nicotine, other known flavors, etc.

[0022] A ninth aspect is the seventh aspect, wherein the flavor-generating sheet includes a tobacco sheet.

[0023] According to the ninth aspect, the tobacco sheet is efficiently heated, and an aerosol or a flavor can be generated.

[0024] A tenth aspect is the seventh aspect, wherein the flavor-generating sheet includes a tobacco sheet and a non-tobacco sheet carrying an aerosol source or a flavor-generating substrate.

[0025] According to the tenth aspect, the non-tobacco sheet and the tobacco sheet are efficiently heated, and an aerosol or flavor can be generated.

[0026] An eleventh aspect is characterized in that, in any one of the first to tenth aspects, the container has a first portion that generates a flavor when heated and includes the elastically deformable sheet, and a second portion that is adjacent to the first portion in the longitudinal direction and through which the flavor generated in the first portion passes.

[0027] According to the eleventh aspect, the flavor generated in the first portion can be passed through the second portion, and therefore the flavor can be cooled in the second portion. In this specification, the longitudinal direction can also be referred to as the axial direction of the stick-shaped flavor generating article or the insertion direction of the heater into the flavor generating article.

[0028] A twelfth aspect is the eleventh aspect, wherein the second portion has a first stopper that prevents the elastically deformable sheet from moving from the first portion toward the second portion.

[0029] According to the twelfth aspect, when the heater is inserted into the through-hole, the elastically deformable sheet can be prevented from moving toward the second portion, thereby preventing the flavor generating article from being damaged when the heater is inserted.

[0030] A thirteenth aspect is characterized in that in the eleventh or twelfth aspect, the elastically deformable sheet has a second stopper that prevents the elastically deformable sheet from moving from the first portion toward the opposite side of the second portion.

[0031] According to the thirteenth aspect, when the heater is removed from the through-hole, it is possible to prevent the elastically deformable sheet from moving toward the opposite side of the second portion, i.e., the elastically deformable sheet from being removed from the first portion together with the heater. Therefore, even if the heater is removed from the through-hole, the elastically deformable sheet can be left in the first portion, so that the flavor-generating article after use can be easily disposed of.

[0032] A fourteenth aspect is the thirteenth aspect, wherein the second stopper is a sealing sheet that covers an end face of the elastically deformable sheet and the through hole.

[0033] According to the fourteenth aspect, by inserting the heater into the through hole so as to break the sealing sheet, the flavor-generating article can be heated by the heater while the sealing sheet is positioned on the end face of the elastically deformable sheet. Therefore, when the heater is pulled out of the through hole after use, the sealing sheet positioned on the end face of the elastically deformable sheet can prevent the elastically deformable sheet from coming out of the first portion together with the heater.

[0034] A fifteenth aspect is any one of the first to fourteenth aspects, further comprising a wrapping sheet surrounding the outside of the elastically deformable sheet, the wrapping sheet having a density of 50 g / m 2 More than 100g / m 2 The gist is that it has the following basis weight.

[0035] According to the fifteenth aspect, the wrapping sheet can maintain an appropriate shape against deformation of the elastically deformable sheet. 2 If the basis weight is less than 100 g / m, the wrapping sheet will be more susceptible to deformation than the elastically deformable sheet and may not be able to maintain the proper shape. 2 If the basis weight is more than 100 g / m, the elastically deformable sheet surrounded by the wrapping sheet may be unlikely to deform.

[0036] According to a sixteenth aspect, there is provided a smoking system comprising the flavor generating article according to any one of the first to fifteenth aspects and a flavor inhaler including the heater, the diameter of the through hole being smaller than the maximum length of the heater perpendicular to the insertion direction.

[0037] According to the sixteenth aspect, the through hole can be expanded by inserting the heater into the through hole. This can deform the elastically deformable sheet of the flavor-generating article. For example, when the heater is a plate-shaped heater, the cross-sectional shape of the through hole is deformed flat by the heater, and the elastically deformable sheet can contact or approach the main surface of the plate-shaped heater. When the heater is a pin-shaped heater, when the heater is inserted into the through hole, the elastically deformable sheet is compressed in the thickness direction, and the elastically deformable sheet can contact or approach the peripheral surface of the heater. This can efficiently heat the flavor-generating article.

[0038] According to a seventeenth aspect, there is provided a smoking system. The smoking system includes a flavor generating article according to any one of the first to fifteenth aspects, and a flavor inhaler including the heater. The flavor inhaler has an opening for receiving the flavor generating article. The maximum diameter of the opening is larger than the maximum diameter of the flavor generating article, and the minimum diameter of the opening is smaller than the minimum diameter of the flavor generating article.

[0039] According to the seventeenth aspect, the flavor generating article is inserted into the opening of the flavor inhaler, so that the flavor generating article can be deformed to fit the shape of the opening. Specifically, the flavor generating article can be deformed to fit the minimum diameter of the opening, and its cross section can be deformed to be flat. This allows the elastically deformable sheet of the flavor generating article to come into contact with or approach the heater, so that the flavor generating article can be efficiently heated.

[0040] An eighteenth aspect is the sixteenth or seventeenth aspect, wherein an inner circumferential length of the through hole is equal to or greater than an outer circumferential length of the heater.

[0041] According to the eighteenth aspect, even if the flavor generating article and the through-hole are deformed, a gap can be generated between the heater and the flavor generating article (the inner surface of the flavor generating article that defines the through-hole), thereby preventing an increase in the suction resistance and more reliably delivering the flavor or aerosol generated by the flavor generating article to the user through this gap. Note that the peripheral length of the heater here may be the maximum peripheral length of the portion of the heater that is inserted into the flavor generating article.

[0042] A 19th aspect is characterized in that, in any of the 16th to 18th aspects, the heater is a plate-shaped heater having a first surface and a second surface opposite the first surface, and when the plate-shaped heater is inserted into the through hole, the elastically deformable sheet deforms so that the distance between the elastically deformable sheet and the first surface or the second surface becomes smaller.

[0043] According to the nineteenth aspect, the elastically deformable sheet deforms and comes into contact with or close to the first surface or the second surface of the heater, so that the flavor generating article can be heated efficiently.

[0044] A twentieth aspect is based on any one of the sixteenth to nineteenth aspects, and is characterized in that the through-hole is defined by an inner surface of the elastically deformable sheet or the flavor-generating sheet.

[0045] According to the twentieth aspect, when a heater is inserted into the through-hole, the inner surface of the elastically deformable sheet or the flavor-generating sheet can be in direct contact with the heater, so that the elastically deformable sheet or the flavor-generating sheet can be efficiently heated.

[0047] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are designated by the same reference numerals and redundant description will be omitted.

[0048] FIG. 1 is a schematic diagram of a flavor generating article according to the present embodiment. FIG. 2 is a side view of the flavor generating article taken along the line 2-2 in FIG. 1. In FIG. 1, a first portion 30 of the flavor generating article 10 is shown in a cross-sectional view, and a second portion 20 is shown in a side view. The flavor generating article 10 is a stick-shaped part as a whole, and is configured to generate a flavor by heating and provide the flavor to a user who inhales the flavor generating article 10. As shown in FIG. 1, the flavor generating article 10 has a first portion 30 and a second portion 20 adjacent to the first portion 30 in the longitudinal direction.

[0049] The first portion 30 is configured to generate a flavor by heating. As shown in FIG. 1 and FIG. 2, the first portion 30 includes an elastically deformable sheet 32. The second portion 20 is configured to allow the flavor generated in the first portion 30 to pass through. This allows the flavor generated in the first portion 30 to be cooled in the second portion 20. The flavor generating article 10 has a through hole 36 into which a heater of a flavor inhaler described later can be inserted, and the through hole 36 can be at least partially defined by a cylindrical elastically deformable sheet 32. As shown in FIG. 2, the through hole 36 and the first portion 30 have a substantially circular cross section when viewed in the longitudinal direction. In this embodiment, the elastically deformable sheet 32 ​​is elastically deformable in its thickness direction (i.e., in the radial direction of the cylindrical elastically deformable sheet 32). This allows the elastically deformable sheet 32 ​​to elastically deform in the thickness direction relative to the heater when the heater is inserted into the through hole 36, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet 32 ​​contains a flavor, or when a sheet containing a flavor is present inside the elastically deformable sheet 32, the sheet containing the flavor can be brought into closer contact or proximity with the heater, so that the flavor-generating article 10 can be heated efficiently.

[0050] In the example shown in FIG. 1 and FIG. 2, the elastically deformable sheet 32 ​​may be a non-tobacco sheet. The non-tobacco sheet means a sheet of non-tobacco raw materials, and may contain tobacco raw materials. Specifically, the elastically deformable sheet 32 ​​may be composed of non-tobacco fibers such as pulp fibers or nonwoven fabric, and may contain an aerosol source. The non-tobacco fibers used in the non-tobacco sheet may contain non-pulp fibers. Non-pulp fibers are fibers other than pulp fibers. Pulp fibers are an aggregate of cellulose fibers extracted from plants such as wood, and are usually used as a raw material for paper. Examples of pulp fibers include waste paper pulp, chemical pulp, and mechanical pulp.

[0051] The non-tobacco sheet may contain a binder. The binder is an adhesive for binding fibers together. Any binder known in the art may be used. The non-tobacco sheet may contain an emulsifier. The emulsifier enhances the affinity between the lipophilic aerosol-generating base material and the hydrophilic non-pulp fibers. Any known emulsifier may be used, and examples of such emulsifiers include emulsifiers having an HLB value of 8 to 18.

[0052] The aerosol source is a material that generates an aerosol by vaporizing through heating and cooling, or by atomizing. Any known aerosol source can be used, and examples of such aerosol sources include glycerin, polyhydric alcohols such as propylene glycol (PG), triethyl citrate (TEC), triacetin, etc. This aerosol source can also be added to the tobacco sheet 34b described below.

[0053] The non-tobacco sheet may include a flavor-generating substrate. The flavor-generating substrate is a material that imparts a flavor and is preferably a tobacco material. Specific tobacco materials include shredded dried tobacco leaves, ground leaf tobacco, and tobacco extracts (extracts made from water, an organic solvent, or a mixed solution thereof). Ground leaf tobacco is a particle obtained by grinding leaf tobacco. The ground leaf tobacco can have an average particle size of, for example, 30 to 120 μm. The grinding can be performed using a known grinder, and may be dry grinding or wet grinding. Therefore, ground leaf tobacco is also called leaf tobacco particles. In this embodiment, the average particle size is determined by a laser diffraction / scattering method, and specifically, is measured using a laser diffraction particle size distribution measuring device (for example, HORIBA LA-950). In addition, the type of tobacco is not limited, and flue-cured, Burley, Orient, native, and other Nicotiana tabacum and Nicotiana rustica varieties can be used. The amount of the flavor-generating base material in the non-tobacco sheet is not particularly limited, but is preferably 1 to 30% by weight, more preferably 10 to 20% by weight.

[0054] The flavor-generating substrate may also contain a flavoring. A flavoring is a substance that provides an aroma or flavor. The flavoring may be a natural flavoring or a synthetic flavoring. A single type of flavoring may be used as the flavoring, or a mixture of multiple types of flavorings may be used. Any flavoring that is generally used in smoking articles may be used as the flavoring, and specific examples thereof will be described later. The flavoring may be contained in the non-tobacco sheet in an amount that allows the smoking article to provide a preferred aroma or flavor, and for example, the amount is preferably 1 to 30% by weight, more preferably 10 to 20% by weight, in the non-tobacco sheet.

[0055] The flavoring may be any flavoring that is commonly used, such as essential oils, natural flavorings, and synthetic flavorings. The flavoring may be liquid or solid, and may have any properties. Suitable flavors include flavorings selected from tobacco extracts and tobacco components, sugar and sugar-based flavors, licorice, cocoa, chocolate, fruit juice and fruit, spices, liquor, herbs, vanilla, and flower-based flavors, or combinations thereof. Specific examples include flavorings selected from isothiocyanates, indoles and derivatives thereof, ethers, esters, ketones, fatty acids, higher aliphatic alcohols, higher aliphatic aldehydes, higher aliphatic hydrocarbons, thioethers, thiols, terpene-based hydrocarbons, phenol ethers, phenols, furfural and derivatives thereof, aromatic alcohols, aromatic aldehydes, lactones, or combinations thereof.

[0056] For example, a wide variety of flavoring ingredients can be used, such as those described in "Collection of Well-Known and Commonly Used Technology (Flavors)" (March 14, 2007, published by the Japan Patent Office), "The Latest Encyclopedia of Flavors (Popular Edition)" (February 25, 2012, edited by Soichi Arai, Akio Kobayashi, Izumi Yajima, and Michiaki Kawasaki, Asakura Publishing), and "Tobacco Flavoring for Smoking Products" (June 1972, RJ Reynolds Tobacco Company).

[0057] From the viewpoint of imparting a good smoking taste, examples of the flavoring include acetanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, trans-anethole, star anise oil, apple juice, Peru balsam oil, beeswax absolute, benzaldehyde, benzoin resinoid, benzyl alcohol, benzyl benzoate, benzyl phenylacetate, benzyl propionate, 2,3-butanedione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamom oil, carob absolute, β-carotene, carrot juice, L-carvone, β-caryophyllene, cassia bark oil, cedarwood oil, celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acid, cinnamyl alcohol, cinnamyl cinnamate, citronella oil, and DL-citronella. , Clary sage extract, Cocoa, Coffee, Cognac oil, Coriander oil, Cumin aldehyde, Davana oil, δ-Decalactone, γ-Decalactone, Decanoic acid, Dill herb oil, 3,4-Dimethyl-1,2-cyclopentanedione, 4,5-Dimethyl-3-hydroxy-2,5-dihydrofuran-2-one, 3,7-Dimethyl-6-octenoic acid, 2,3-Dimethylpyrazine, 2,5-Dimethylpyrazine, 2,6-Dimethylpyrazine, Ethyl 2-methylbutyrate, Ethyl acetate, Ethyl butyrate, Ethyl hexanoate, Ethyl isovalerate, Ethyl lactate, Ethyl laurate, Ethyl levulinate, Ethyl maltol, Ethyl octanoate, Ethyl oleate, Ethyl palmitate, Ethyl phenylacetate, Ethyl propionate, Ethyl stearate, Ethyl valerate, Ethyl vanillin, Ethyl vanillin glucoside, 2-Ethyl-3,(5 or 6)-Dimethylpyrazine, 5-ethyl-3-hydroxy-4-methyl-2(5H)-furanone, 2-ethyl-3-methylpyrazine, eucalyptol, fenugreek absolute, gene absolute, gentian root infusion, geraniol, geranyl acetate, grape juice, guaiacol, guava extract, gamma-heptalactone, gamma-hexalactone, hexanoic acid, cis-3-hexen-1-ol, hexyl acetate, hexyl alcohol, phenylhexyl acetate, honey, 4-hydroxy-3-pentenoic acid, la , 4-Hydroxy-4-(3-hydroxy-1-butenyl)-3,5,5-trimethyl-2-cyclohexen-1-one, 4-(para-hydroxyphenyl)-2-butanone, Sodium 4-Hydroxyundecanoate, Immortelle Absolute, β-Ionone, Isoamyl Acetate, Isoamyl Butyrate, Isoamyl Phenylacetate, Isobutyl Acetate, Isobutyl Phenylacetate, Jasmine Absolute, Cola Nut Tincture, Labdanum Oil, Lemon Terpeneless Oil, Licorice Extract, Linalool, Linalyl Acetate, Robe Dioscorea officinalis root oil, maltol, maple syrup, menthol, menthone, L-menthyl acetate, paramethoxybenzaldehyde, methyl 2-pyrrolyl ketone, methyl anthranilate, methyl phenylacetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methylvaleric acid, mimosa absolute, tsammi fruit, myristic acid, nerol, nerolidol, gamma-nonalactone, nutmeg oil, delta-octalactone, octanal, octanoic acid, orange flower oil, orange oil, orris root oil, palmitic acid, omega-pentadecane Calactone, Peppermint Oil, Petitgrain Paraguay Oil, Phenethyl Alcohol, Phenethyl Phenylacetate, Phenylacetic Acid, Piperonal, Plum Extract, Propylguaethol, Propyl Acetate, 3-Propylidenephthalide, Prune Juice, Pyruvic Acid, Raisin Extract, Rose Oil, Rum, Sage Oil, Sandalwood Oil, Spearmint Oil, Styrax Absolute, Marigold Oil, Tea Distillate, Alpha-Terpineol, Terpinyl Acetate, 5,6,7,8-Tetrahydroquinoxaline, 1,5,5,9-Tetramethyl-13-oxacyclo(8.3.0.0(4.9))tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil, tomato extract, 2-tridecanone, triethyl citrate, 4-(2,6,6-trimethyl-1-cyclohexenyl)2-buten-4-one, 2,6,6-trimethyl-2-cyclohexene-1,4-dione, 4-(2,6,6-trimethyl-1,3-cyclohexadienyl)2-buten-4-one, 2,3,5-trimethyl Examples of the fragrance include methylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin, veratraldehyde, violet leaf absolute, citral, mandarin oil, 4-(acetoxymethyl)toluene, 2-methyl-1-butanol, ethyl 10-undecenoate, isoamyl hexanoate, 1-phenylethylacetic acid, lauric acid, 8-mercaptomenthone, sinenthal, and hexyl butyrate, and menthol is particularly preferred. These fragrances may be used alone or in combination of two or more.

[0058] The type of solid flavor is not particularly limited, and from the viewpoint of imparting a good smoking taste, examples thereof include flavors selected from cocoa powder, carob powder, coriander powder, licorice powder, orange peel powder, herb powder, flower powder, spice powder, tea powder, etc., or combinations thereof.

[0059] The flavor-generating base material may also contain a cooling agent or a flavoring agent. The type of the cooling agent is not particularly limited, and from the viewpoint of imparting a good smoking taste, examples of the cooling agent include menthol, camphor, isopulegol, cineole, peppermint oil, peppermint oil, eucalyptus oil, 2-l-menthoxyethanol (COOLACT (registered trademark) 5), 3-l-menthoxypropane-1,2-diol (COOLACT (registered trademark) 10), l-menthyl-3-hydroxybutyrate (COOLACT (registered trademark) 20), p-menthane-3,8-diol (COOLACT (registered trademark) 38D), N-( 2-Hydroxy-2-phenylethyl)-2-isopropyl-5,5-dimethylcyclohexane-1-carboxamide (COOLACT® 370), N-(4-(cyanomethyl)phenyl)-2-isopropyl-5,5-dimethylcyclohexanecarboxamide (COOLACT® 400), N-(3-hydroxy-4-methoxyphenyl)-2-isopropyl-5,5-dimethylcyclohexanecarboxamide, N-ethyl-p-menthane-3-carboxamide (WS-3), ethyl-2-(p-menthane N-(4-methoxyphenyl)-p-menthanecarboxamide (WS-12), 2-isopropyl-N,2,3-trimethylbutyramide (WS-23), 3-l-menthoxy-2-methylpropane-1,2-diol, 2-l-menthoxyethan-1-ol, 3-l-menthoxypropan-1-ol, 4-l-menthoxybutan-1-ol, menthyl lactate (FEMA3748), menthone glycerin acetal (FrescolatMGA, FEMA38 07, FEMA3808), 2-(2-l-menthyloxyethyl)ethanol, menthyl glyoxylate, 2-pyrrolidone-5-carboxylate menthyl, menthyl succinate (FEMA3810), N-(2-(pyridin-2-yl)-ethyl)-3-p-menthanecarboxamide (FEMA4549), N-(ethoxycarbonylmethyl)-p-menthane-3-carboxamide, N-(4-cyanomethylphenyl)-p-menthanecarboxamide, and N-(4-aminocarbonylphenyl)-p-menthane. The cooling agents may be used alone or in combination of two or more.

[0060] The type of the flavoring agent is not particularly limited, and from the viewpoint of imparting a good smoking taste, examples include sweeteners (sugars (glucose, fructose, isomerized sugar, caramel, etc.)), acidulants (organic acids, etc.), other flavoring agents (materials that impart umami, bitterness, saltiness, etc.), etc. In addition, lipids (wax, wax, fatty acids (short-chain, medium-chain, long-chain fatty acids, etc.)) may be added as desired.

[0061] When flavorings, cooling agents, and flavorings are contained in the tobacco shreds, in one embodiment, the total content of these is not particularly limited, but from the viewpoint of imparting a good smoking taste, is usually 10000 ppm or more, preferably 20000 ppm or more, more preferably 25000 ppm or more, and usually 70000 ppm or less, preferably 50000 ppm or more, more preferably 40000 ppm or less, and even more preferably 33000 ppm or less. In another embodiment, the total amount is preferably 2% by weight or more, more preferably 5% by weight or more, and preferably 20% by weight or less, more preferably 10% by weight or less.

[0062] The elastically deformable sheet 32 ​​preferably has a volume void ratio of 85% or more and 95% or less. This allows the sheet containing the flavor (the elastically deformable sheet 32 ​​or the tobacco sheet 34b described later) to be in more appropriate contact or proximity with the heater. If the volume void ratio of the elastically deformable sheet 32 ​​is less than 85%, the elastically deformable sheet has too strong a repulsive force, making it difficult to deform the flavor-generating article. In this case, there is a risk that the airflow resistance of the flavor-generating article will increase too much. If the volume void ratio of the elastically deformable sheet 32 ​​is more than 95%, the elastically deformable sheet has too weak a repulsive force, and when the flavor-generating article is deformed, the contact between the inner wall of the flavor-generating article and the heater will be weak, which may affect delivery.

[0063] In addition, it is preferable that the elastically deformable sheet 32 ​​has an airflow resistance of 0 mmH2O or more and 150 mmH2O or less. This allows the airflow resistance during inhalation by the user to be appropriate even if no gap occurs between the heater and the elastically deformable sheet 32. If the airflow resistance of the elastically deformable sheet 32 ​​exceeds 150 mmH2O, the suction resistance becomes too high, and the user may feel uncomfortable when inhaling. Note that the airflow resistance of the elastically deformable sheet 32 ​​here means the airflow resistance in the length direction of the elastically deformable sheet 32, i.e., the left-right direction (air flow direction) in FIG. 1.

[0064] It is preferable that the elastically deformable sheet 32 ​​has a predetermined hardness in the thickness direction. By controlling the hardness, the flavor generating article 10 can be easily deformed, and the flavor generating article 10 and the heater can be closely attached to each other, thereby improving the heating efficiency.

[0065] The elastically deformable sheet 32 ​​has a density of 30 g / m 2 More than 100g / m 2 It is preferable that the non-tobacco sheet has a basis weight of 30 g / m or less. This allows the flavor-containing sheet to be in more appropriate contact with the heater. 2 If the basis weight is less than 100 g / m, the flavor may be quickly exhausted, or the elastically deformable sheet may be too thin and prone to tearing during the manufacturing process, resulting in poor manufacturability, or the elastically deformable sheet may be torn when the heater is inserted. 2 If it is more than 100 mm, it becomes difficult to bend the flexible deformable sheet and to deform the flavor generating article 10. In this case, the heat capacity becomes large, so that the temperature rise of the flavor generating article 10 becomes slow, and it may take a long time before the first puff is possible.

[0066] As described above, the elastically deformable sheet 32 ​​is preferably a non-tobacco sheet carrying an aerosol source or a flavor-generating substrate, whereby the elastically deformable sheet 32 ​​can be efficiently heated by contacting or approaching a heater to generate an aerosol or a flavor.

[0067] As shown in Figs. 1 and 2, the flavor-generating article 10 preferably has a flavor-generating sheet 34. In the illustrated example, the flavor-generating sheet 34 is located inside the elastically deformable sheet 32, is formed in a cylindrical shape, and defines at least a part of the through-hole 36 together with the elastically deformable sheet 32. As a result, the elastically deformable sheet 32 ​​is deformed and the elastically deformable sheet 32 ​​comes into contact with or approaches the heater, so that the flavor-generating sheet 34 located inside the elastically deformable sheet 32 ​​can be brought into contact with or approaches the heater. As a result, the flavor-generating sheet 34 is efficiently heated to generate an aerosol or a flavor. Not limited to this, in this embodiment, the through-hole 36 can be defined by the inner surface of the elastically deformable sheet 32 ​​or the flavor-generating sheet 34. As a result, when the heater 120 is inserted into the through-hole 36, the inner surface of the elastically deformable sheet 32 ​​or the flavor-generating sheet 34 can directly come into contact with the heater 120, so that the elastically deformable sheet 32 ​​or the flavor-generating sheet 34 can be efficiently heated.

[0068] 2, the flavor-generating sheet 34 can include a non-tobacco sheet 34a carrying an aerosol source or a flavor-generating substrate. This allows the aerosol source or flavor-generating substrate of the non-tobacco sheet 34a to be efficiently heated to generate an aerosol, flavor, or the like. The aerosol source or flavor-generating substrate carried by the non-tobacco sheet 34a can be the above-mentioned aerosol source or flavor-generating substrate that can be carried by the elastically deformable sheet 32.

[0069] 2, the flavor-generating sheet 34 can include a tobacco sheet 34b. This allows the tobacco sheet 34b to be efficiently heated and generate aerosol or flavor. In the example shown in FIG. 2, the tobacco sheet 34b is located inside the non-tobacco sheet 34a, but the tobacco sheet 34b may be located outside the non-tobacco sheet 34a.

[0070] The tobacco sheet 34b may contain, for example, tobacco (corresponding to an example of a flavor generating substrate) and polyhydric alcohol (corresponding to an example of an aerosol source). The polyhydric alcohol may include glycerin, propylene glycol, sorbitol, xylitol, and erythritol. These polyhydric alcohols may be used alone or in combination of two or more in the tobacco sheet 34b. These polyhydric alcohols may also be added to the above-mentioned elastically deformable sheet 32. The tobacco sheet 34b may be formed into a sheet shape by mixing powdered tobacco and polyhydric alcohol with a binder. Examples of the binder that may be used include guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (sodium salt of carboxymethylcellulose), pullulan and hydroxypropyl cellulose (HPC), methyl cellulose, and hydroxyl methyl cellulose. This binder may also be added to the above-mentioned elastically deformable sheet 32.

[0071] Pulp may be added to the tobacco sheet 34b. Pulp can improve the strength of the tobacco sheet 34b. On the other hand, pulp does not have to be added to the tobacco sheet 34b. If pulp is not used, the proportion of tobacco in the tobacco sheet 34b increases accordingly, and this is expected to improve the smoking taste.

[0072] The weight percent of the binder that may be added to the tobacco sheet 34b is, for example, preferably 0% to 60% and more preferably 0% to 10% relative to the weight of the tobacco sheet 34b. The tobacco sheet 34b may have a blending ratio (weight percent) of, for example, 5% to 40% polyhydric alcohol, 50% to 90% tobacco, 0% to 10% binder, and 0% to 10% pulp. An acid such as lactic acid, palmitic acid, or benzoic acid may also be added to the tobacco sheet 34b.

[0073] 2, the flavor-generating sheet 34 can include a tobacco sheet 34b and a non-tobacco sheet 34a. However, the flavor-generating sheet 34 can include only one of the tobacco sheet 34b and the non-tobacco sheet 34a.

[0074] Fig. 3 is a cross-sectional view of the second portion 20 taken along line 3-3 of Fig. 1. As shown in Fig. 3, the second portion 20 has a cylindrical wrapping sheet 21 and a first stopper 22 located inside the wrapping sheet 21. In this embodiment, the basis weight of the wrapping sheet 21 is 50 g / m 2 More than 150g / m 2 It is preferable that the thickness is less than 50 g / m 2 More than 100g / m 2 It is more preferable that the wrapping sheet 21 is 50 g / m or less. It is preferable that the wrapping sheet 21 surrounds the outside of the elastically deformable sheet 32 ​​as shown in FIG. 2. Specifically, it is preferable that the wrapping sheet 21 extends from the second portion 20 to the first portion 30. This allows the wrapping sheet 21 to maintain an appropriate shape against deformation of the elastically deformable sheet 32. 2 If the wrapping sheet 21 has a basis weight of less than 100 g / m, it may be more easily deformed than the elastically deformable sheet 32 ​​and may not be able to maintain a proper shape. 2 If the basis weight is more than 100 g / m2, the elastically deformable sheet 32 ​​surrounded by the wrapping sheet 21 may be difficult to deform.

[0075] The first stopper 22 can prevent the elastically deformable sheet 32 ​​from moving from the first portion 30 toward the second portion 20. Specifically, in this embodiment, when viewed from the longitudinal direction, at least a part of the first stopper 22 of the second portion 20 is located on the same radius as the elastically deformable sheet 32. In other words, at least a part of the first stopper 22 is located so as to contact the elastically deformable sheet 32 ​​in the longitudinal direction. As a result, even if a force is applied to the elastically deformable sheet 32 ​​by the heater in a direction toward the second portion 20 when the heater is inserted into the through hole 36, the first stopper 22 can contact the elastically deformable sheet 32 ​​to prevent the elastically deformable sheet 32 ​​from moving. Therefore, the flavor-generating article 10 can be prevented from being destroyed when the heater is inserted. In this embodiment, the first stopper 22 can be a piece of paper whose both ends are connected to different positions on the inner surface of the cylindrical wrapping sheet 21 and whose length between the ends is longer than the diameter of the wrapping sheet 21. Without being limited thereto, the first stopper 22 may take any form capable of preventing the elastically deformable sheet 32 ​​from moving from the first portion 30 towards the second portion 20.

[0076] FIG. 4A is a side view of a flavor-generating article 10 according to another embodiment. FIG. 4A shows a side view in the direction of the arrow 2-2 shown in FIG. 1. The flavor-generating article 10 preferably has a second stopper 38 that prevents the elastically deformable sheet 32 ​​from moving from the first part 30 toward the opposite side of the second part 20. The second stopper 38 is located at a position on the opposite side of the first part 30 from the second part 20, and at least a part of the second stopper 38 is located on the same radius as the elastically deformable sheet 32 ​​when viewed in the longitudinal direction. In other words, at least a part of the second stopper 38 is located at a position on the opposite side of the first part 30 from the second part 20 so as to contact the elastically deformable sheet 32 ​​in the longitudinal direction. This makes it possible to prevent the elastically deformable sheet 32 ​​from moving toward the opposite side of the second part 20, i.e., to prevent the elastically deformable sheet 32 ​​from coming out of the first part 30 together with the heater, when the heater is removed from the through hole 36. Therefore, even when the heater is removed from the through-hole 36, the elastically deformable sheet 32 ​​can be left in the first portion 30, so that the flavor generating article 10 can be easily disposed of after use.

[0077] In the example shown in FIG. 4A, the second stopper 38 is a sealing sheet that covers the end face of the elastically deformable sheet 32 ​​and the through hole 36. Specifically, the second stopper 38 extends in the radial direction of the first part 30 of the flavor-generating article 10, and a perforation 38a may be formed in the approximate center of the second stopper 38. FIG. 4B is a schematic diagram of the flavor-generating article 10 after a heater is inserted. In FIG. 4B, the first part 30 is shown in a cross-sectional view. As shown in FIG. 4B, when the heater is inserted into the through hole 36, the second stopper 38 may be cut by the heater, for example, along the perforation 38a. By inserting the heater into the through hole 36 so as to break the second stopper 38, the flavor-generating article 10 may be heated by the heater while the second stopper 38 is positioned on the end face of the elastically deformable sheet 32. Therefore, when the heater is pulled out from the through-hole 36 after use, the second stopper 38 located on the end face of the elastically deformable sheet 32 ​​can prevent the elastically deformable sheet 32 ​​from coming out of the first portion 30 together with the heater. The second stopper 38 can take any form that can prevent the elastically deformable sheet 32 ​​from moving from the first portion 30 toward the opposite side of the second portion 20, such as a center hole filter.

[0078] Next, a flavor inhaler for heating the flavor generating article 10 will be described. FIG. 5 is a cross-sectional view showing the main part of the flavor inhaler 100 in the width direction of the heater 120. FIG. 6 is a cross-sectional view showing the main part of the flavor inhaler 100 in the thickness direction of the heater 120. The flavor inhaler 100 can constitute a smoking system together with the flavor generating article 10. As shown in FIG. 5 and FIG. 6, the flavor inhaler 100 includes a housing 110 and a heater 120. The housing 110 has an opening 112 at one end, and accommodates at least a part of the flavor generating article 10 inserted into the opening 112 through the opening 112. The housing 110 is made of, for example, a resin, and in particular, can be made of PC (polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyether ether ketone), or a polymer alloy containing multiple types of polymers, or a metal such as aluminum. Here, housing 110 is configured so that the cross-sectional area in a cross section perpendicular to the longitudinal direction of housing 110 is smallest in the vicinity of opening 112 .

[0079] The housing 110 also has a shaping guide 114 and a pressing rib 116. The shaping guide 114 is provided in the opening 112, and deforms the cross-sectional shape of the flavor generating article 10 inserted into the housing 110. The pressing rib 116 is provided on the inner peripheral surface of the housing 110, and urges the flavor generating article 10 inserted into the housing 110 toward the heater 120, thereby deforming the shape of the flavor generating article 10. The detailed configurations of the shaping guide 114 and the pressing rib 116 and their function of deforming the flavor generating article 10 will be described later.

[0080] In the illustrated example, the heater 120 is a flat PTC (Positive Temperature Coefficient) heater that is inserted into the flavor generating article 10 housed in the housing 110 and heats the flavor generating article 10 from the inside. The heater 120 deforms the shape of the flavor generating article 10 inserted into the housing 110 to match the shape of the heater 120. The function of the heater 120 to deform the flavor generating article 10 will be described later. Here, the shaping guide 114, the holding rib 116, and the heater 120 deform the shape of the flavor generating article 10 after it is housed in the housing 110 from the shape of the flavor generating article 10 before it is housed in the housing 110. The heater 120 may be a plate-shaped heater, and is not limited to the resistance heating type heater 120 as in this embodiment, but may be, for example, a heater that is induction heated by an induction coil and is used as a susceptor.

[0081] Next, a description will be given of the relationship between the flavor generating article 10, the housing 110, and the heater 120 when the flavor generating article 10 is accommodated in the flavor inhaler 100, i.e., when the flavor generating article 10 is inserted from one end side to the other end side of the housing 110. Figs. 7 to 9 are cross-sectional views showing a state in which the flavor generating article 10 is accommodated in the flavor inhaler 100. Note that in Figs. 7 to 9, the elastically deformable sheet 32 ​​and the flavor generating sheet 34 of the flavor generating article 10 are shown as one annular sheet 33.

[0082] Fig. 7 shows a state when the flavor generating article 10 passes through the shaping guide 114, in terms of a cross section in the width direction of the heater 120 and a cross section perpendicular to the longitudinal direction of the housing 110 at the inlet portion 118 of the shaping guide 114. Fig. 8 shows a state when the flavor generating article 10 passes through the pressing rib 116, in terms of a cross section in the width direction of the heater 120 and a cross section perpendicular to the longitudinal direction of the housing 110 at the middle portion and the other end portion of the pressing rib 116. Fig. 9 shows a state when the flavor generating article 10 is accommodated in a predetermined accommodation position in the housing 110, in terms of a cross section in the width direction of the heater 120 and a cross section perpendicular to the longitudinal direction of the housing 110 near the other end portion of the heater 120.

[0083] As shown in FIG. 7, the shaping guide 114 has a tapered portion 117 and an inlet portion 118. The tapered portion 117 is configured to expand toward one end side of the housing 110, and guides the insertion of the flavor generating article 10 into the flavor inhaler 100. It is preferable that the maximum diameter of the opening 112 of the flavor inhaler 100 is larger than the maximum diameter of the flavor generating article 10, and the minimum diameter of the opening 112 is smaller than the minimum diameter of the flavor generating article 10. In this case, the flavor generating article 10 can be deformed to fit the shape of the opening 112 by inserting the flavor generating article 10 into the opening 112 of the flavor inhaler 100. Specifically, the flavor generating article 10 can be deformed to fit the minimum diameter of the opening 112, and its cross section can be deformed to be flat. As a result, the elastically deformable sheet 32 ​​of the flavor generating article 10 comes into contact with or approaches the heater 120, and the flavor generating article 10 can be efficiently heated. The opening 112 here may be the portion having the smallest cross-sectional area among the openings 112 of the flavor inhaler 100 into which the flavor generating article 10 is inserted. Specifically, the opening 112 here may be the inlet portion 118 in the example shown in Fig. 7. The inlet portion 118 may have an elliptical cross section, and may be configured so that the major axis is larger than the diameter of the flavor generating article 10 after it is housed in the housing 110 and the minor axis is approximately the same length as the diameter of the flavor generating article 10 before it is housed in the housing 110. The inlet portion 118 may also be configured so that the inner periphery length is shorter than the outer periphery length of the flavor generating article 10.

[0084] As shown in FIG. 8, the heater 120 has a pointed shape and is configured to widen toward the other end. As a result, as the flavor-generating article 10 passes through the shaping guide 114 and is inserted, the shape of the flavor-generating article 10 is deformed to conform to the shape of the heater 120. Specifically, the heater 120 is a plate-shaped heater having a first surface 120a and a second surface 120b facing the first surface 120a, and as shown in FIG. 8, when the heater 120 is inserted into the through-hole 36, the elastically deformable sheet 32 ​​is deformed so that the distance between the elastically deformable sheet 32 ​​and the first surface 120a or the second surface 120b is reduced. As a result, the elastically deformable sheet 32 ​​is deformed and comes into contact with or close to the first surface 120a or the second surface 120b of the heater 120, so that the flavor-generating article 10 can be efficiently heated.

[0085] It is preferable that the diameter of the through hole 36 of the flavor generating article 10 is smaller than the maximum length perpendicular to the insertion direction of the heater 120. In this case, as shown in FIG. 8, the heater 120 is inserted into the through hole 36, and the through hole 36 can be expanded by the heater 120. This can deform the elastically deformable sheet 32 ​​of the flavor generating article 10. As shown in the example, when the heater 120 is plate-shaped, the cross-sectional shape of the through hole 36 is deformed flat by the heater 120, and the elastically deformable sheet 32 ​​can contact or approach the main surface of the plate-shaped heater 120. Also, when the heater 120 is pin-shaped, when the heater 120 is inserted into the through hole 36, the elastically deformable sheet 32 ​​is compressed in the thickness direction, and the elastically deformable sheet 32 ​​can contact or approach the peripheral surface of the heater 120. This can efficiently heat the flavor generating article 10. Furthermore, the heater 120 spreads the flavor generating article 10, thereby preventing the flavor generating article 10 from falling off.

[0086] The pressing rib 116 is provided on the inner peripheral surface of the housing 110 along the thickness direction of the heater 120, and is composed of a pair of tapered surfaces facing each other (see FIG. 6). The pressing rib 116 is arranged so as to overlap with an area where the width of the heater 120 gradually increases in the longitudinal direction of the housing 110. Here, the pressing rib 116 is configured so that the protruding distance gradually increases toward the other end side of the housing 110, and is configured so that the protruding distance is maximum at the position where the width of the heater 120 is maximum. At this time, the length between the tapered surfaces is configured to be smaller than the diameter of the flavor-generating article 10. As a result, when the flavor-generating article 10 passes through the pressing rib 116, the pressing rib 116 biases the flavor-generating article 10, which has been pushed out in the width direction of the heater 120, in the thickness direction of the heater 120, so that the flavor-generating article 10 is deformed into a flat shape. Furthermore, the pressing rib 116 biases the flavor generating article 10, thereby preventing the flavor generating article 10 from falling off.

[0087] The inner circumferential length of the through-hole 36 of the flavor generating article 10 is preferably equal to or greater than the outer circumferential length of the heater 120. This allows a gap to be generated between the heater 120 and the flavor generating article 10 (the inner surface of the flavor generating article 10 that defines the through-hole 36) even if the flavor generating article 10 and the through-hole 36 are deformed as shown in Fig. 9, thereby preventing an increase in the resistance to inhalation and enabling the flavor or aerosol generated in the flavor generating article 10 to be more reliably delivered to the user through this gap.

[0088] FIG. 10 is a side view of a flavor generating article 10 according to another embodiment. FIG. 10 shows a side view of the flavor generating article in the direction of the arrow 2-2 shown in FIG. 1. The flavor generating article 10 shown in FIG. 10 is different from the flavor generating article 10 shown in FIG. 1 and FIG. 2 in the structure of the elastically deformable sheet 32. Specifically, the elastically deformable sheet 32 ​​of the flavor generating article 10 shown in FIG. 10 is a non-tobacco sheet having a corrugated cross section when viewed from the longitudinal direction. In the illustrated example, the corrugated cross section of the non-tobacco sheet is deformed, so that the elastically deformable sheet 32 ​​can be elastically deformed in its thickness direction. In addition, the non-tobacco sheet having a corrugated cross section has gaps (between the waves) along its longitudinal direction, so that a flow path through which the flavor generated in the flavor generating article 10 passes can be defined. In the example shown in FIG. 10, the flavor generating sheet 34 has only a tobacco sheet 34b.

[0089] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible within the scope of the claims and the technical ideas described in the specification and drawings. Note that any shape or material not directly described in the specification and drawings is within the scope of the technical ideas of the present invention as long as it has the functions and effects of the present invention.
