Disclosure of Invention

Problems to be solved by the invention

A so-called internal heating type heating device in which a fragrance source is heated from the inside by a heater plate, a heating pin, a heating base, or the like can directly heat the fragrance source to a high temperature. It is required to efficiently heat the fragrance source using such an internal heating type heating apparatus.

An object of the present invention is to provide a flavor generating article and a smoking system that can be efficiently heated.

Means for solving the problems

According to the 1 st aspect, a flavor-generating article that generates flavor by heating can be provided. The flavor generating article has a through hole into which a heater can be inserted and a tubular elastic deformation piece defining the through hole. The elastic deformation sheet is elastically deformable in the thickness direction thereof.

According to the 1 st aspect, when the heater is inserted into the through hole, the elastic deformation piece is elastically deformed in the thickness direction with respect to the heater, and is easily brought into contact with or close to the heater. Therefore, in the case where the elastically deformable sheet contains a fragrance, or in the case where a sheet containing a fragrance is present inside the elastically deformable sheet, the sheet containing a fragrance can be brought into further contact with or close to the heater, and therefore the fragrance-generating article can be efficiently heated.

In the aspect 2, in the aspect 1, the elastically deformable sheet has a volume void ratio of 85% or more and 95% or less.

According to claim 2, the sheet containing the fragrance can be brought into contact with or close to the heater more appropriately. When the volume void ratio of the elastic deformation sheet is less than 85%, the elastic deformation sheet has an excessively strong elastic resilience, and it is difficult to deform the flavor-generating article. In this case, there is a risk that the ventilation resistance of the flavor-generating article excessively increases. When the volume void ratio of the elastic deformation sheet is more than 95%, the elastic deformation sheet has weak resilience, and when the flavor-generating article is deformed, the contact between the inner wall of the flavor-generating article and the heater is weakened, and there is a risk of affecting the conveyance.

The gist of claim 3 is that, in claim 1 or claim 2, the elastically deformable sheet has an air passage resistance of 0mmH ₂ O or more and 150mmH ₂ O or less.

According to claim 3, a gap is not generated between the heater and the elastically deformable sheet, and ventilation resistance at the time of suction by the user can be made appropriate. If the ventilation resistance of the elastic deformation sheet is more than 150mmH ₂ O, the suction resistance becomes too high, and there is a risk that the user feels uncomfortable with suction.

The gist of claim 4 is that, in any of the aspects 1 to 3, the elastically deformable sheet is a non-tobacco sheet having a weight per unit area of 30g/m ² or more and 100g/m ² or less.

According to the 4 th aspect, the sheet containing the fragrance can be brought into contact with the heater more appropriately. When the weight per unit area of the elastic deformation sheet is less than 30g/m ², the following hidden troubles exist: immediately dispersing the fragrance; the elastic deformation sheet becomes too thin and is liable to be broken or the like during the manufacturing process, and the manufacturing adaptability becomes poor; the elastically deformable sheet breaks upon insertion of the heater. When the weight per unit area of the elastic deformation sheet is more than 100g/m ², it is difficult to bend the elastic deformation sheet and deform the flavor-generating article 10. In this case, the heat capacity increases, and therefore, the temperature of the flavor-generating article 10 increases slowly, which may take a long time until the first smoking can be performed.

The gist of claim 5 is that, in any of claims 1 to 4, the elastically deformable sheet is a non-tobacco sheet carrying an aerosol source or a flavor generating base material.

According to the 5 th aspect, the elastic deformation sheet is brought into contact with or close to the heater, whereby the elastic deformation sheet can be efficiently heated to generate aerosol or flavor.

The gist of claim 6 is that, in any of the aspects 1 to 5, the elastically deformable sheet is a non-tobacco sheet having a wavy cross section as viewed from the longitudinal direction.

According to the 6 th aspect, the elastic deformation sheet can be elastically deformed in the thickness direction thereof by deforming the wavy cross section of the non-tobacco sheet. Further, since the non-tobacco sheet having the wave-shaped cross section has a gap (between waves) along the longitudinal direction thereof, a flow path through which flavor or the like generated by the flavor-generating article passes can be defined.

The gist of claim 7 is that, in any of the aspects 1 to 6, the sheet includes a flavor generating sheet positioned inside the elastic deformation sheet.

According to the 7 th aspect, the elastic deformation sheet is brought into contact with or close to the heater, so that the flavor generating sheet positioned inside the elastic deformation sheet can be brought into contact with or close to the heater, and the flavor generating sheet can be efficiently heated to generate aerosol or flavor.

The gist of claim 8 is that, in claim 7, the flavor-generating sheet comprises a negative carrier gas sol source or a non-tobacco sheet of a flavor-generating base material.

According to the 8 th aspect, the aerosol source or the flavor generating substrate of the non-tobacco sheet can be efficiently heated to generate aerosol, flavor, or the like. In the present specification, the flavor-generating base material to be supported on the non-tobacco sheet may include, for example, a tobacco extract, synthetic nicotine, and other known flavors.

In the case of claim 9, the flavor-generating sheet according to claim 7 includes a tobacco sheet.

According to the 9 th aspect, the tobacco sheet can be efficiently heated to generate aerosol or flavor.

The gist of claim 10 is that, in claim 7, the flavor-generating sheet comprises a tobacco sheet and a non-tobacco sheet carrying an aerosol source or a flavor-generating base material.

According to the 10 th aspect, the non-tobacco sheet and the tobacco sheet can be efficiently heated to generate aerosol or flavor.

The 11 th aspect is the gist of any one of the 1 st to 10 th aspects, wherein the system comprises: the first part (1) is heated to generate a fragrance and includes the elastic deformation sheet, and the second part (2) is adjacent to the first part (1) in the longitudinal direction and passes the fragrance generated by the first part (1).

According to claim 11, the fragrance generated in the 1 st part can be passed through the 2 nd part, and therefore the fragrance can be cooled in the 2 nd part. In the present specification, the longitudinal direction may be the axial direction of the rod-shaped flavor generating article or the insertion direction of the heater into the flavor generating article.

In the 12 th aspect, in the 11 th aspect, the 2 nd portion includes a1 st stopper for preventing the elastic deformation piece from moving from the 1 st portion to the 2 nd portion.

According to claim 12, the elastically deformable sheet can be prevented from moving toward the 2 nd portion when the heater is inserted into the through hole. Therefore, the damage of the flavor generating article at the time of the heater insertion can be suppressed.

The gist of claim 13 is that, in claim 11 or claim 12, there is provided a2 nd stopper for preventing the elastic deformation piece from moving from the 1 st part to the opposite side of the 2 nd part.

According to aspect 13, the movement of the elastic deformation piece to the opposite side of the 2 nd portion when the heater is pulled out from the through hole, that is, the pulling-out of the elastic deformation piece from the 1 st portion together with the heater can be suppressed. Therefore, even if the heater is pulled out from the through hole, the elastic deformation piece can be left in the 1 st part, so that the used flavor-generating article can be easily disposed of.

In the 14 th aspect, in the 13 th aspect, the 2 nd stopper is a sealing sheet covering an end surface of the elastic deformation sheet and the through hole.

According to the 14 th aspect, by inserting the heater into the through hole so as to break the seal piece, the flavor generating article can be heated by the heater while the seal piece is positioned on the end surface of the elastic deformation piece. Therefore, when the heater is pulled out of the through hole after use, the seal piece located on the end face of the elastic deformation piece can suppress the elastic deformation piece from being pulled out of the 1 st part together with the heater.

The 15 th aspect is the object of any one of the 1 st to 14 th aspects, wherein the elastic deformation sheet comprises an outer wrapping sheet surrounding an outer side of the elastic deformation sheet, and the outer wrapping sheet has a weight per unit area of 50g/m ² to 100g/m ².

According to the 15 th aspect, the exterior sheet can maintain an appropriate shape with respect to the deformation of the elastic deformation sheet. When the outer cover sheet has a weight per unit area of less than 50g/m ², the outer cover sheet is more likely to deform than the elastic deformation sheet, and there is a risk that an appropriate shape cannot be maintained. When the outer cover sheet has a weight per unit area of more than 100g/m ², there is a risk that the elastic deformation sheet surrounded by the outer cover sheet is hardly deformed.

According to the 16 th aspect, a smoking system may be provided. The smoking system includes the flavor generating article according to any one of aspects 1 to 15, and the flavor aspirator including the heater. The diameter of the through hole is smaller than the maximum length of the heater perpendicular to the insertion direction.

According to the 16 th aspect, by inserting the heater into the through hole, the through hole is expanded by the heater. Thus, the elastically deformable sheet of the flavor-generating article is deformed. For example, in the case where the heater is a plate-like heater, the cross-sectional shape of the through hole is deformed to be flat by the heater, and accordingly, the elastically deformable piece may be in contact with or close to the main surface of the plate-like heater. In addition, in the case of a needle-shaped heater, when the heater is inserted into the through hole, the elastic deformation piece is compressed in the thickness direction, and the elastic deformation piece can be brought into contact with or close to the circumferential surface of the heater. Thus, the flavor generating article can be efficiently heated.

According to mode 17, there can be provided a smoking system. The smoking system includes the flavor generating article according to any one of aspects 1 to 15, and the flavor aspirator including the heater. The flavor aspirator 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.

According to the 17 th aspect, by inserting the flavor generating article into the opening of the flavor aspirator, the flavor generating article can be deformed in accordance with the shape of the opening. Specifically, the flavor-generating article is deformed in accordance with the minimum diameter of the opening, and its cross section is deformed flat. Thus, the elastically deformable sheet of the flavor-generating article contacts or approaches the heater, and the flavor-generating article can be efficiently heated.

In the eighth aspect, in the 16 th or 17 th aspect, the inner circumference of the through hole is equal to or larger than the outer circumference of the heater.

According to the 18 th 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 defining the through-hole), and therefore, an increase in suction resistance can be prevented, and the flavor or aerosol generated by the flavor-generating article can be delivered to the user more reliably through the gap. The outer circumferential length of the heater may be the maximum outer circumferential length of the portion of the heater into which the fragrance generating article is inserted.

In the 19 th aspect, in any one of the 16 th to 18 th aspects, the heater is a plate-shaped heater having a1 st surface and a2 nd surface facing the 1 st surface, and when the plate-shaped heater is inserted into the through hole, the elastic deformation piece is deformed so that a distance between the elastic deformation piece and the 1 st surface or the 2 nd surface is reduced.

According to the 19 th aspect, since the elastic deformation piece is deformed so that the elastic deformation piece contacts or approaches the 1 st or 2 nd surface of the heater, the flavor generating article can be efficiently heated.

The gist of claim 20 is that, in any of the 16 th to 19 th aspects, the through hole is defined by an inner surface of the elastic deformation sheet or the flavor generating sheet.

According to the 20 th aspect, since the inner surface of the elastic deformation sheet or the flavor generating sheet can directly contact the heater when the heater is inserted into the through hole, the elastic deformation sheet or the flavor generating sheet can be efficiently heated.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings described below, the same or corresponding components are denoted by the same reference numerals, and the same repetitive description is omitted.

Fig. 1 is a schematic view of a flavor generating article according to the present embodiment. Fig. 2 is a side view of the flavor generating article of fig. 1, looking at 2-2. In fig. 1, a portion 130 of a flavour generating article 10 is shown in cross-section and a portion 220 is shown in side view. The flavor generating article 10 is a rod-shaped member as a whole, and is configured to generate flavor by heating and to provide flavor to a user who sucks the flavor generating article 10. As shown in fig. 1, the flavor generating article 10 has a 1 st part 30 and a2 nd part 20 adjacent to the 1 st part 30 in the longitudinal direction.

Part 130 is configured to generate a fragrance by heating. As shown in fig. 1 and 2, the 1 st portion 30 includes an elastically deformable sheet 32. The 2 nd part 20 is configured to pass the fragrance generated by the 1 st part 30. Thus, the scent generated by section 130 may be cooled in section 2 20. The flavor generating article 10 has a through hole 36 into which a heater of a flavor aspirator described later can be inserted, and the through hole 36 may be defined at least in part by the tubular elastic deformation sheet 32. As shown in fig. 2, the through hole 36 and the 1 st portion 30 have a substantially circular cross section as viewed in the longitudinal direction. In the present embodiment, the elastic deformation piece 32 is elastically deformable in the thickness direction thereof (i.e., the radial direction of the cylindrical elastic deformation piece 32). Thus, when the heater is inserted into the through hole 36, the elastically deforming piece 32 elastically deforms in the thickness direction with respect to the heater, and is easily brought into contact with or close to the heater. Therefore, in the case where the elastically deforming sheet 32 contains the fragrance, or in the case where the sheet containing the fragrance is present inside the elastically deforming sheet 32, the sheet containing the fragrance can be brought into further contact with or close to the heater, and therefore the fragrance generating article 10 can be efficiently heated.

In the example shown in fig. 1 and 2, the elastically deformable sheet 32 may be a non-tobacco sheet. The non-tobacco sheet refers to a material formed from a non-tobacco material into a sheet, and may contain a tobacco material. Specifically, the elastically deformable sheet 32 may be made of non-tobacco fibers such as pulp fibers or nonwoven fabrics, and may contain an aerosol source. The non-tobacco fibers used in the non-tobacco sheet may comprise non-pulp fibers. Non-pulp fibers refer to fibers other than pulp fibers. Pulp fibers are aggregates of cellulose fibers extracted from plants such as wood, and are generally used as a raw material for paper. As pulp fibers, there may be mentioned: waste pulp, chemical pulp, mechanical pulp, and the like.

The non-tobacco sheet may comprise a binder. The binder is an adhesive for bonding fibers to each other and the like. As the binder, a binder known in the art can be used. The non-tobacco sheet may comprise an emulsifier. The emulsifier can increase the affinity of the lipophilic aerosol-generating substrate for hydrophilic non-pulp fibers. As the emulsifier, a known emulsifier can be used, and examples thereof include emulsifiers having an HLB value of 8 to 18.

An aerosol source refers to a material that generates an aerosol by heating and vaporizing and cooling, or generates an aerosol by atomizing. As the aerosol source, a known material can be used, and as an example thereof, there can be mentioned: polyhydric alcohols such as glycerin and Propylene Glycol (PG), triethyl citrate (TEC), and glyceryl triacetate. The aerosol source may be added to the tobacco sheet 34b described later.

The non-tobacco sheet may comprise a flavour generating substrate. The flavor generating base material is a material imparting a flavor, and is preferably a tobacco material. Specific tobacco materials include: cut materials obtained by cutting dried tobacco leaves, crushed tobacco leaves, or tobacco extracts (extracts obtained by using water, an organic solvent, or a mixed solution thereof), and the like. The tobacco leaf crushed material is particles obtained by crushing tobacco leaves. The average particle diameter of the crushed tobacco leaves may be, for example, 30 to 120. Mu.m. The pulverization may be performed using a known pulverizer, and may be performed by dry pulverization or wet pulverization. Accordingly, the crushed tobacco leaves are also referred to as tobacco particles. In the present embodiment, the average particle diameter can be obtained by a laser diffraction/scattering method, and specifically, can be measured by using a laser diffraction type particle diameter distribution measuring apparatus (for example, LA-950 manufactured by horiba ltd). The type of tobacco is not limited, and a yellow variety, a burley variety, an oriental variety, a local variety, another tobacco (Nicotiana tabacum) line variety, a tobacco (Nicotiana rustica) line variety, and the like can be used. The amount of the flavor-imparting 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.

The flavour generating substrate may also comprise a perfume. The perfume is a substance that provides a fragrance or flavor. The perfume may be natural perfume or synthetic perfume. As the perfume, 1 kind of perfume may be used, or a mixture of plural kinds of perfumes may be used. As the flavoring, any flavoring commonly used in smoking articles can be used, and specific examples thereof will be described later. The flavoring may be included in the non-tobacco sheet in an amount that the smoking article is capable of providing the preferred flavor, taste, and for example, in an amount of preferably 1 to 30% by weight, more preferably 10 to 20% by weight, in the non-tobacco sheet.

The perfume may be any commonly used perfume such as essential oil, natural perfume, or synthetic perfume, and any perfume may be used. The shape of the material may be any shape, and may be any shape. Preferred flavoring agents (flavoring) include flavoring agents selected from tobacco extracts and tobacco components, sugar and saccharide flavoring agents, licorice (Lycoris), cocoa, chocolate, fruit juice and fruit, flavoring, wine, herbs, vanilla, and flower flavoring agents, or combinations thereof. Specifically, the aromatic hydrocarbon may be a perfume selected from isothiocyanates, indoles and derivatives thereof, ethers, esters, ketones, fatty acids, aliphatic higher alcohols, aliphatic higher aldehydes, aliphatic higher hydrocarbons, thioethers, thiols, terpene hydrocarbons, phenol ethers, phenols, furfurals and derivatives thereof, aromatic alcohols, aromatic aldehydes, lactones, and the like, or a combination thereof.

For example, a wide variety of fragrances described in "known/conventional technology set (fragrance)" (release of patent office at 3/14/2007), "topical reference book (popular version) of latest fragrance" (release at 2/25/2012), barren 1/small Lin Zhangfu/daycare spring/kawasaki general, sho, toward a bookstore), or "Tobacco Flavoring for Smoking Products" (release at 6/1972, r.j.reynolds TOBACCO com) can be used.

In addition, the flavour generating substrate may comprise a cooling agent or flavour. The type of the cooling agent is not particularly limited, and examples thereof include those giving a good flavor and taste: menthol, camphor, isopulegol, eucalyptol, peppermint oil, eucalyptus oil, 2-l-menthoxyethanol (COOLACT (registered trademark) 5), 3-l-menthoxypropyl-1, 2-diol (COOLACT (registered trademark) 10), l-3-Hydroxy-butyrate (COOLACT (registered trademark) 20), p-Alkane-3, 8-diol (COOLACT (registered trademark) 38D), N- (2-hydroxy-2-phenethyl) -2-isopropyl-5, 5-dimethylcyclohexane-1-carboxamide (COOLACT (registered trademark) 370), N- (4- (aminomethyl) phenyl) -2-isopropyl-5, 5-dimethylcyclohexane-carboxamide (COOLACT (registered trademark) 400), N- (3-hydroxy-4-methoxyphenyl) -2-isopropyl-5, 5-dimethylcyclohexane-carboxamide, N-ethyl-p-Alkyl-3-carboxamides (WS-3), ethyl-2- (p-methyl)Alkyl-3-carboxamide acetate (WS-5), N- (4-methoxyphenyl) -p-Alkanecarboxamide (WS-12), 2-isopropyl-N, 2, 3-trimethylbutyramide (WS-23), 3-l-menthoxy-2-methylpropan-1, 2-diol, 2-l-menthoxyethane-1-ol, 3-l-menthoxypropane-1-ol, 4-l-menthoxybutan-1-ol, menthyl lactate (FEMA 3748), menthone glycerol ketal (Frescolat MGA, FEMA3807, FEMA 3808), 2- (2-l) menthoneOxyethyl) ethanol,Glyoxylate, 2-pyrrolidone-5-carboxylic acidEsters, succinic acidEsters (FEMA 3810), N- (2- (pyridin-2-yl) -ethyl) -3-pAlkylcarboxamides (FEMA 4549), N- (ethoxycarbonylmethyl) -p-Alkyl-3-carboxamides, N- (4-cyanomethylphenyl) -p-Alkanecarboxamides and N- (4-aminocarbonylphenyl) -p-An alkane, and the like. The cooling agents may be used alone or in combination of 2 or more.

The type of the flavoring agent is not particularly limited, and examples thereof include those giving a good flavor and taste: sweeteners (sugars (glucose, fructose, isomerized sugar, caramel, etc)), acidulants (organic acids, etc.), other flavoring agents (raw materials exhibiting umami, bitter, salty, etc.), and the like. Further, lipids (wax), wax (u), fatty acids (short chain, medium chain, long chain fatty acids, etc.) may be optionally added.

When the flavor, the cooling agent, and the flavoring agent are contained in the tobacco shred, the total content of these components is not particularly limited, but is usually 10000ppm or more, preferably 20000ppm or more, more preferably 25000ppm or more, and is usually 70000ppm or less, preferably 50000ppm, more preferably 40000ppm or less, more preferably 33000ppm or less, from the viewpoint of imparting a good flavor. 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.

The elastically deformable sheet 32 preferably has a volume void ratio of 85% or more and 95% or less. This enables the sheet (the elastically deformable sheet 32 or the tobacco sheet 34b described later) containing the flavor to be brought into further proper contact with or close to the heater. When the volume void ratio of the elastic deformation sheet 32 is less than 85%, the elastic deformation sheet has an excessively strong elastic resilience, and it is difficult to deform the flavor-generating article. In this case, there is a risk that the ventilation resistance of the flavor-generating article excessively increases. When the volume void ratio of the elastic deformation sheet 32 is larger than 95%, the elastic force of the elastic deformation sheet is weak, and when the flavor-generating article is deformed, the contact between the inner wall of the flavor-generating article and the heater is weakened, and there is a possibility that the conveyance is affected.

The elastically deformable sheet 32 preferably has an air passage resistance of 0mmH ₂ O or more and 150mmH ₂ O or less. This can generate a gap between the heater and the elastically deformable sheet 32, and can make the ventilation resistance of the user appropriate at the time of suction. If the ventilation resistance of the elastic deformation sheet 32 is greater than 150mmH ₂ O, the suction resistance becomes too high, and there is a risk that the user feels uncomfortable with suction. The air flow resistance of the elastic deformation sheet 32 here refers to the air flow resistance in the longitudinal direction of the elastic deformation sheet 32, that is, in the left-right direction (air flow direction) in fig. 1.

The elastically deformable sheet 32 preferably has a given hardness in the thickness direction. By controlling the hardness, the fragrance generating article 10 can be easily deformed, and the fragrance generating article 10 can be closely adhered to the heater, thereby improving the heating efficiency.

The elastically deformable sheet 32 is preferably a non-tobacco sheet having a weight per unit area of 30g/m ² or more and 100g/m ² or less. This enables the sheet containing the fragrance to be brought into further proper contact with the heater. When the weight per unit area of the elastic deformation sheet 32 is less than 30g/m ², there are the following problems: the fragrance is quickly dispersed; the elastic deformation sheet becomes too thin and is liable to be broken or the like during the manufacturing process, and the manufacturing adaptability becomes poor; the elastically deformable sheet breaks upon insertion of the heater. When the weight per unit area of the elastic deformation sheet 32 is greater than 100g/m ², it is difficult to bend the elastic deformation sheet and deform the flavor-generating article 10. In this case, the heat capacity increases, and therefore, the temperature of the flavor-generating article 10 increases slowly, which may take a long time until the first smoking can be performed.

As described above, the elastically deformable sheet 32 is preferably a non-tobacco sheet carrying an aerosol source or a flavour-generating substrate. Thus, the elastically deformable sheet 32 is brought into contact with or close to the heater, whereby the elastically deformable sheet 32 can be efficiently heated to generate aerosol or flavor.

As shown in fig. 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 positioned inside the elastic deformation sheet 32, is formed in a tubular shape, and defines at least a part of the through hole 36 together with the elastic deformation sheet 32. Thus, the elastic deformation piece 32 is deformed to bring the elastic deformation piece 32 into contact with or close to the heater, and the fragrance generating piece 34 located inside the elastic deformation piece 32 can be brought into contact with or close to the heater. As a result, the fragrance generating sheet 34 can be efficiently heated to generate aerosol or fragrance. In the present embodiment, the through-hole 36 may be defined by the inner surface of the elastic deformation sheet 32 or the fragrance generating sheet 34, but is not limited thereto. Thus, when the heater 120 is inserted into the through hole 36, the inner surface of the elastic deformation sheet 32 or the fragrance generating sheet 34 can directly contact the heater 120, and therefore the elastic deformation sheet 32 or the fragrance generating sheet 34 can be efficiently heated.

As shown in fig. 2, the flavour generating sheet 34 may comprise a negative carrier gas sol source or a non-tobacco sheet 34a of a flavour generating substrate. Thus, the aerosol source or the flavor-generating substrate other than the tobacco sheet 34a can be efficiently heated to generate an aerosol, a flavor, or the like. The aerosol source or the flavor generating base material to be supported by the non-tobacco sheet 34a may be the aerosol source or the flavor generating base material that can be supported by the elastically deformable sheet 32.

In addition, as shown in fig. 2, the flavour generating sheet 34 may comprise a tobacco sheet 34b. Thus, the tobacco sheet 34b can be efficiently heated to generate aerosol or flavor. In the example shown in fig. 2, the tobacco sheet 34b is positioned inside the non-tobacco sheet 34a, but the tobacco sheet 34b may be positioned outside the non-tobacco sheet 34 a.

The tobacco sheet 34b may include, for example, tobacco (corresponding to an example of a flavor generating base material) and polyol (corresponding to an example of an aerosol source). The polyol may contain glycerol, propylene glycol, sorbitol, xylitol, and erythritol. These polyols may be used alone or in combination of 2 or more for the tobacco sheet 34b. These polyols may also be added to the elastically deformable sheet 32 described above. The tobacco sheet 34b may be formed into a sheet shape by mixing a binder with powdered tobacco and a polyol. As the binder, for example, guar gum, xanthan gum, CMC (carboxymethyl cellulose), CMC-Na (sodium salt of carboxymethyl cellulose), pullulan, hydroxypropyl cellulose (HPC), methyl cellulose, hydroxymethyl cellulose, and the like can be used. The adhesive may be added to the elastically deformable sheet 32.

In addition, pulp may be added to the tobacco sheet 34 b. The pulp may increase the strength of the tobacco sheet 34 b. On the other hand, pulp may not be added to the tobacco sheet 34 b. If pulp is not used, the proportion of tobacco in the tobacco sheet 34b increases accordingly, and thus an improvement in flavor can be expected.

The weight% of the binder that can be added to the tobacco sheet 34b is, for example, preferably 0% or more and 60% or less, more preferably 0% or more and 10% or less, relative to the weight of the tobacco sheet 34 b. The tobacco sheet 34b may have a blend ratio (weight percentage) of, for example, 5% to 40% of polyol, 50% to 90% of tobacco, 0% to 10% of binder, and 0% to 10% of pulp. Further, an acid such as lactic acid, palmitic acid, or benzoic acid may be added to the tobacco sheet 34 b.

As shown in fig. 2, the flavour generating sheet 34 may comprise a tobacco sheet 34b and a non-tobacco sheet 34a. The flavor-generating sheet 34 may include only any one of the tobacco sheet 34b and the non-tobacco sheet 34a, but is not limited thereto.

Fig. 3 is a cross-sectional view of the portion 220 of fig. 1, looking at 3-3. As shown in fig. 3, the 2 nd portion 20 has a cylindrical exterior sheet 21 and a1 st stopper 22 located inside the exterior sheet 21. In the present embodiment, the weight per unit area of the exterior sheet 21 is preferably 50g/m ² to 150g/m ², more preferably 50g/m ² to 100g/m ². The outer wrap sheet 21 preferably surrounds the outside of the elastically deforming sheet 32 as shown in fig. 2. Specifically, the overwrap sheet 21 preferably extends from the 2 nd portion 20 to the 1 st portion 30. Thus, the exterior sheet 21 can maintain an appropriate shape with respect to the deformation of the elastic deformation sheet 32. If the outer cover sheet 21 has a weight per unit area of less than 50g/m ², the outer cover sheet is more likely to be deformed than the elastic deformation sheet 32, and there is a risk that an appropriate shape cannot be maintained. If the outer cover sheet 21 has a weight per unit area of more than 100g/m ², the elastic deformation sheet 32 surrounded by the outer cover sheet 21 may be difficult to deform.

The 1 st stopper 22 can prevent the elastically deforming piece 32 from moving from the 1 st portion 30 to the 2 nd portion 20. Specifically, in the present embodiment, at least a part of the 1 st stopper 22 of the 2 nd portion 20 is located on the same radius as the elastically deforming piece 32 as viewed in the longitudinal direction. In other words, at least a portion of the 1 st stopper 22 contacts the elastically deforming piece 32 in the longitudinal direction. Thus, even if a force is applied to the elastic deformation piece 32 by the heater in the direction toward the 2 nd portion 20 when the heater is inserted into the through hole 36, the 1 st stopper 22 contacts the elastic deformation piece 32, and movement of the elastic deformation piece 32 can be prevented. Therefore, the damage of the flavor generating article 10 at the time of the heater insertion can be suppressed. In the present embodiment, the 1 st stopper 22 may be a paper having both ends connected to different positions of the inner surface of the tubular exterior sheet 21 and having a length between the ends longer than the diameter of the exterior sheet 21. Without being limited to the above, the 1 st stopper 22 may take any form capable of preventing the elastically deforming sheet 32 from moving from the 1 st part 30 to the 2 nd part 20.

Fig. 4A is a side view of another embodiment of a scent-generating article 10. Fig. 4A shows a side view of the view 2-2 shown in fig. 1. The flavor generating article 10 preferably has a2 nd stopper 38 capable of preventing the elastically deforming sheet 32 from moving from the 1 st part 30 to the opposite side of the 2 nd part 20. In the 2 nd stopper 38, at a position on the opposite side of the 1 st portion 30 from the 2 nd portion 20, at least a part of the 2 nd stopper 38 is located on the same radius as the elastically deforming piece 32 as viewed in the longitudinal direction. In other words, at least a part of the 2 nd stopper 38 is located at a position contacting the elastically deforming piece 32 in the longitudinal direction at a position on the opposite side of the 1 st part 30 from the 2 nd part 20. This can suppress the movement of the elastic deformation piece 32 to the opposite side of the 2 nd portion 20 when the heater is pulled out of the through hole 36, that is, can suppress the elastic deformation piece 32 from being pulled out of the 1 st portion 30 together with the heater. Therefore, even if the heater is pulled out from the through hole 36, the elastic deformation piece 32 can be left in the 1 st portion 30, and therefore, the used flavor-generating article 10 can be easily discarded.

In the example shown in fig. 4A, the 2 nd stopper 38 is a sealing sheet covering the end surface of the elastically deformable sheet 32 and the through hole 36. Specifically, the 2 nd stop 38 may extend in the radial direction of the 1 st portion 30 of the flavour generating article 10 and form a seam 38a at a substantially central portion thereof. Fig. 4B is a schematic view of the flavor generating article 10 after the heater is inserted. In fig. 4B, section 1, 30, is shown in cross-section. As shown in fig. 4B, when the heater is inserted into the through hole 36, the 2 nd stopper 38 is cut by the heater along the joint 38a, for example. By inserting the heater into the through-hole 36 so as to break the 2 nd stopper 38, the flavor generating article 10 can be heated by the heater while the 2 nd stopper 38 is positioned on the end surface of the elastically deforming sheet 32. Therefore, when the heater is pulled out of the through hole 36 after use, the elastic deformation piece 32 can be restrained from being pulled out of the 1 st portion 30 together with the heater by the 2 nd stopper 38 located on the end surface of the elastic deformation piece 32. The 2 nd stop 38 may be any form capable of preventing movement of the elastically deformable sheet 32 from the 1 st section 30 to the opposite side of the 2 nd section 20, such as a center hole filter.

Next, a description will be given of a flavor aspirator for heating the flavor generating article 10. Fig. 5 is a cross-sectional view showing a main portion of the fragrance aspirator 100 in the width direction of the heater 120. Fig. 6 is a cross-sectional view showing a main portion of the fragrance aspirator 100 in a thickness direction of the heater 120. The flavor aspirator 100 may constitute a smoking system with the flavor generating article 10. As shown in fig. 5 and 6, the flavor aspirator 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 is formed of, in particular, a metal such as PC (polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene), acrylonitrile-Butadiene-Styrene (PEEK), PEEK (polyetheretherketone), a polymer alloy containing a plurality of polymers, or aluminum. Here, the housing 110 is configured such that a cross-sectional area of a cross section orthogonal to the longitudinal direction of the housing 110 is smallest near the opening 112.

In addition, the housing 110 has a swage guide 114 and a hold-down flange 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 flange 116 is provided on the inner circumferential surface of the housing 110, and presses the flavor generating article 10 inserted into the housing 110 against the heater 120, thereby deforming the shape of the flavor generating article 10. The detailed configuration of the shaping guide 114 and the pressing flange 116 and the function of deforming the flavor generating article 10 will be described later.

In the illustrated example, the heater 120 is a flat plate-shaped 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 along 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 pressing flange 116, and the heater 120 deform the shape of the flavor-generating article 10 after being accommodated in the housing 110, compared with the shape of the flavor-generating article 10 before being accommodated in the housing 110. The heater 120 may be plate-shaped, and is not limited to the resistance heating type heater 120 as in the present embodiment, and may be, for example, a heater that is used as a heating base and inductively heated by an induction coil.

Next, a relationship between the flavor generating article 10 and the housing 110 and the heater 120 when the flavor generating article 10 is housed in the flavor aspirator 100, that is, when the flavor generating article 10 is inserted from one end side to the other end side of the housing 110 will be described. Fig. 7 to 9 are sectional views showing a state in which the flavor generating article 10 is accommodated in the flavor aspirator 100. In fig. 7 to 9, the elastically deformable sheet 32 and the flavor-generating sheet 34 of the flavor-generating article 10 are shown as 1 annular sheet 33.

Fig. 7 shows a state in which the flavor generating article 10 passes through the shaping guide 114, with respect to a cross section in the width direction of the heater 120 and a cross section orthogonal to the longitudinal direction of the housing 110 at the inlet portion 118 of the shaping guide 114. Fig. 8 shows a state in which the flavor generating article 10 passes through the pressing flange 116, with respect to a cross section in the width direction of the heater 120 and a cross section orthogonal to the longitudinal direction of the housing 110 at the middle portion and the other end portion of the pressing flange 116. Fig. 9 shows a state in which the flavor generating article 10 is accommodated in a predetermined accommodation position of the housing 110, with respect to a cross section in the width direction of the heater 120 and a cross section orthogonal to the longitudinal direction of the housing 110 in the vicinity of the other end side end portion of the heater 120.

As shown in fig. 7, the shaping guide 114 has a tapered portion 117 and an inlet portion 118. The tapered portion 117 is formed so as to expand toward one end of the housing 110, and guides insertion of the flavor generating article 10 into the flavor aspirator 100. Preferably, the largest diameter of the opening 112 of the flavour aspirator 100 is larger than the largest diameter of the flavour generating article 10, and the smallest diameter of the opening 112 is smaller than the smallest diameter of the flavour generating article 10. In this case, by inserting the flavor generating article 10 into the opening 112 of the flavor aspirator 100, the flavor generating article 10 is deformed in accordance with the shape of the opening 112. Specifically, the flavor generating article 10 is deformed in accordance with the minimum diameter of the opening 112, and its cross section is deformed flat. Thus, the elastically deforming sheet 32 of the flavor generating article 10 contacts or approaches the heater 120, and the flavor generating article 10 can be efficiently heated. The opening 112 may be a portion having a smallest cross-sectional area in the opening 112 of the flavor aspirator 100 into which the flavor generating article 10 is inserted. Specifically, in the example shown in fig. 7, the opening 112 herein may be the inlet portion 118. The inlet 118 has an elliptical cross section, and may be configured such that the longer diameter is larger than the diameter of the flavor-generating article 10 after being accommodated in the housing 110, and the shorter diameter is substantially the same length as the diameter of the flavor-generating article 10 before being accommodated in the housing 110. The inlet portion 118 may be formed such that the inner circumference is shorter than the outer circumference of the flavor-generating article 10.

As shown in fig. 8, the heater 120 is configured to have a sharp shape and to have a width that expands toward the other end side. Thus, as the flavour generating article 10 is inserted through the shaping guide 114, the shape of the flavour generating article 10 will be deformed along the shape of the heater 120. Specifically, the heater 120 is a plate-shaped heater having a1 st surface 120a and a2 nd surface 120b opposite to the 1 st surface 120a, and as shown in fig. 8, when the heater 120 is inserted into the through hole 36, the elastically deforming piece 32 is deformed so that the distance between the elastically deforming piece 32 and the 1 st surface 120a or the 2 nd surface 120b is reduced. As a result, the elastic deformation sheet 32 is deformed, and the elastic deformation sheet 32 contacts or approaches the 1 st surface 120a or the 2 nd surface 120b of the heater 120, so that the flavor generating article 10 can be efficiently heated.

The diameter of the through hole 36 of the flavor generating article 10 is preferably smaller than the maximum length of the heater 120 perpendicular to the insertion direction. In this case, as shown in fig. 8, the heater 120 is inserted into the through hole 36, whereby the through hole 36 can be expanded by the heater 120. Thus, the elastically deformable sheet 32 of the flavor generating article 10 can be deformed. As in the illustrated example, when the heater 120 is plate-shaped, the cross-sectional shape of the through-hole 36 is deformed to be flat by the heater 120, and accordingly, the elastic deformation piece 32 can be brought into contact with or close to the main surface of the plate-shaped heater 120. In the case where the heater 120 is needle-shaped, the elastic deformation piece 32 is compressed in the thickness direction when the heater 120 is inserted into the through hole 36, and the elastic deformation piece 32 may contact or come close to the circumferential surface of the heater 120. Thus, the flavor generating article 10 can be efficiently heated. Further, the heater 120 expands the flavor generating article 10, so that the flavor generating article 10 can be prevented from falling off.

The pressing flange 116 is provided on the inner circumferential surface of the housing 110 in the thickness direction of the heater 120, and is formed of a pair of tapered surfaces facing each other (see fig. 6). The pressing flange 116 is disposed so as to overlap with a region in which the width of the heater 120 gradually increases along the longitudinal direction of the housing 110. Here, the pressing flange 116 is configured to gradually extend the distance protruding toward the other end side of the housing 110, and is configured to maximize the protruding distance at the position where the width of the heater 120 is maximized. At this time, the length between the tapered surfaces is smaller than the diameter of the flavor generating article 10. Thus, when the flavor generating article 10 passes through the pressing flange 116, the pressing flange 116 abuts against the flavor generating article 10 expanded in the width direction of the heater 120 in the thickness direction of the heater 120, thereby deforming the flavor generating article 10 into a flat shape. In addition, by pressing the flange 116 against the flavor-generating article 10, the flavor-generating article 10 can be prevented from falling off.

The inner circumference of the through hole 36 of the flavor generating article 10 is preferably equal to or greater than the outer circumference of the heater 120. As a result, as shown in fig. 9, even when the flavor generating article 10 and the through-hole 36 are deformed, a gap can be formed between the heater 120 and the flavor generating article 10 (the inner surface of the flavor generating article 10 defining the through-hole 36), and therefore, an increase in suction resistance can be prevented, and flavor or aerosol generated by the flavor generating article 10 can be more reliably delivered to the user through the gap.

Fig. 10 is a side view of another embodiment of a scent-generating article 10. Fig. 10 shows a side view of the scent-generating article of fig. 1, looking at 2-2. The flavor generating article 10 shown in fig. 10 is different from the flavor generating article 10 shown in fig. 1 and 2 in the structure of the elastic deformation 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 wavy cross section as viewed in the longitudinal direction. In the illustrated example, the non-tobacco sheet is deformed in the waveform cross section, so that the elastic deformation sheet 32 can be elastically deformed in the thickness direction. The non-tobacco sheet having a wave-shaped cross section has gaps (between waves) along the longitudinal direction thereof, and can define a flow path through which the flavor or the like generated by the flavor-generating article 10 passes. In the example shown in fig. 10, the flavor generating sheet 34 has only the tobacco sheet 34b.

The embodiments of the present application have been described above, but the present application is not limited to the above embodiments, and various modifications are possible within the scope of the technical ideas described in the claims, the specification, and the drawings. Any shape and material not directly described in the specification and drawings are within the technical spirit of the present application as long as they can function and effect of the present application.
