Description

Flavor-generating article and smoking system

The present invention relates to flavor generating articles and smoking systems.

Conventionally, there are known flavor-generating articles for inhaling flavor, etc. without burning materials (for example, Patent Documents 1 and 2). Such a flavor generating article has a flavor source containing tobacco containing a volatile component, and can be directly heated from inside the flavor source by inserting a heater or the like inside the flavor source.

WO2020/002165 International Publication No. 2020/007879

A so-called internal heating type heating device that heats the 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.

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

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

According to the first aspect, when the heater is inserted into the through-hole, the elastically deformable sheet is elastically deformed in the thickness direction with respect to the heater, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet contains flavor, or when the flavor-containing sheet exists inside the elastically deformable sheet, the flavor-containing sheet can be brought into closer contact with or closer to the heater, thereby generating flavor. Articles can be efficiently heated.

The gist of the second aspect is that in the first aspect, the elastically deformable sheet has a volume porosity of 85% or more and 95% or less.

According to the second aspect, the flavor-containing sheet can be appropriately brought into contact with or close to the heater. When the volume porosity of the elastically deformable sheet is less than 85%, the repulsive force of the elastically deformable sheet is too strong, making it difficult to deform the flavor generating article. Moreover, in this case, there is a possibility that the ventilation resistance of the flavor-generating article may be excessively increased. When the volume porosity of the elastically deformable sheet exceeds 95%, the repulsive force of the elastically deformable 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 becomes weak, resulting in poor delivery. There is a risk of impact.

A gist of a third aspect is that in the first aspect or the second aspect, the elastically deformable sheet has a ventilation resistance of 0 mmH ₂ O or more and 150 mmH ₂ O or less.

According to the third aspect, even if there is no gap between the heater and the elastically deformable sheet, the ventilation resistance when the user sucks can be made appropriate. If the airflow resistance of the elastically deformable sheet exceeds 150 mmH ₂ O, the suction resistance becomes too high, and the user may feel uncomfortable when sucking.

A gist of a fourth aspect is that in any one of the first to third aspects, the elastically deformable sheet is a non-tobacco sheet having a basis weight of 30 g/m ² or more and 100 g/m ² or less.

According to the fourth aspect, the flavor-containing sheet can be brought into more appropriate contact with the heater. If the basis weight of the elastically deformable sheet is less than 30 g/m ² , the flavor is quickly exhausted, or the elastically deformable sheet is too thin and is likely to break during the manufacturing process, resulting in poor production aptitude. There is a risk that the elastically deformable sheet will break when the heater is inserted. If the basis weight of the elastically deformable sheet is more than 100 g/m ² , it becomes difficult to bend the elastically deformable sheet, and it becomes difficult to deform the flavor generating article 10 . Moreover, in this case, since the heat capacity is increased, the temperature rise of the flavor generating article 10 is slowed down, and there is a possibility that it takes time until the first puff is possible.

A gist of a fifth aspect is 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 base material.

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

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

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, since the non-tobacco sheet having a corrugated cross section has gaps (between waves) along its longitudinal direction, it is possible to define channels through which the flavor and the like generated in the flavor generating article pass.

The gist of the seventh aspect is that, in any one of the first to sixth aspects, a flavor generating sheet positioned inside the elastically deformable sheet is included.

According to the seventh aspect, the elastically deformable sheet contacts or approaches the heater, whereby the flavor generating sheet located inside the elastically deformable sheet can be brought into contact with or approach the heater, and the flavor generating sheet is efficiently heated. can generate an aerosol or flavor.

The gist of the eighth aspect is that in the seventh aspect, the flavor generating sheet includes a non-tobacco sheet carrying an aerosol source or a flavor generating base material.

According to the eighth aspect, the non-tobacco sheet aerosol source or flavor generating base material can be efficiently heated to generate an aerosol or flavor. In this specification, the flavor-generating base material carried on the non-tobacco sheet may include, for example, tobacco extract, synthetic nicotine, and other known flavors.

The gist of the ninth aspect is that in the seventh aspect, the flavor generating sheet includes a tobacco sheet.

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

A gist of a tenth aspect is that in the seventh aspect, the flavor generating sheet includes a tobacco sheet and a non-tobacco sheet carrying an aerosol source or a flavor generating base material.

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

According to an eleventh aspect, in any one of the first to tenth aspects, a first portion that generates flavor by heating and includes the elastically deformable sheet is adjacent to the first portion in the longitudinal direction, and the first portion is the first portion. and a second portion through which the flavor generated in the second portion passes.

According to the eleventh aspect, the flavor generated in the first portion can pass through the second portion, so 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.

A twelfth aspect is characterized in that, in the eleventh aspect, the second portion has a first stopper that prevents the elastically deformable sheet from moving from the first portion toward the second portion. .

According to the twelfth aspect, it is possible to prevent the elastic deformation sheet from moving toward the second portion when the heater is inserted into the through hole. Therefore, it is possible to prevent the flavor-generating article from being destroyed when the heater is inserted.

A thirteenth aspect is the eleventh aspect or the twelfth aspect, wherein a second stopper is provided to prevent the elastically deformable sheet from moving from the first portion toward the opposite side of the second portion. do.

According to the thirteenth aspect, when the heater is pulled out from the through-hole, the elastically deformable sheet is prevented from moving toward the opposite side of the second portion, that is, the elastically deformable sheet is prevented from coming out of the first portion together with the heater. be able to. Therefore, even if the heater is pulled out from the through-hole, the elastically deformable sheet can be left in the first portion, so that the used flavor generating article can be easily discarded.

A gist of a fourteenth aspect is that in the thirteenth aspect, the second stopper is a sealing sheet that covers the end surface of the elastically deformable sheet and the through hole.

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 from 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.

A fifteenth aspect is any one of the first to fourteenth aspects, further comprising a wrapping sheet surrounding the outer side of the elastically deformable sheet, wherein the wrapping sheet has a basis weight of 50 g/m ² or more and 100 g/m ² or less. The gist is that it has

According to the fifteenth aspect, the wrapping sheet can maintain an appropriate shape against deformation of the elastically deformable sheet. If the basis weight of the wrapping sheet is less than 50 g/m ² , it may deform more easily than the elastically deformable sheet, making it impossible to maintain an appropriate shape. If the basis weight of the wrapping sheet exceeds 100 g/m ² , the elastically deformable sheet surrounded by the wrapping sheet may be difficult to deform.

According to the sixteenth aspect, a smoking system is provided. A smoking system includes the flavor generating article according to any one of the first to fifteenth aspects and a flavor inhaler provided with the heater. The diameter of the through-hole is smaller than the maximum length perpendicular to the insertion direction of the heater.

According to the sixteenth aspect, the through hole can be expanded by the heater 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 flattened by the heater, and along with this, the elastically deformable sheet may contact or approach the main surface of the plate-shaped heater. Further, in the case where 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 contacts or approaches the peripheral surface of the heater. obtain. This allows efficient heating of the flavor-generating article.

According to the seventeenth aspect, a smoking system is provided. A smoking system includes the flavor generating article according to any one of the first to fifteenth aspects and a flavor inhaler provided with the heater. The flavor inhaler has an opening for receiving the flavor generating article. The maximum diameter of the opening is greater than the maximum diameter of the flavor generating article, and the minimum diameter of the opening is less than the minimum diameter of the flavor generating article.

According to the seventeenth aspect, the flavor-generating article can be deformed according to the shape of the opening by inserting the flavor-generating article into the opening of the flavor inhaler. Specifically, the flavor-generating article can be deformed to fit the minimum diameter of the opening to flatten its cross-section. Thereby, the elastically deformable sheet of the flavor generating article contacts or approaches the heater, and the flavor generating article can be efficiently heated.

The gist of the eighteenth aspect is that in the sixteenth aspect or the seventeenth aspect, the inner peripheral length of the through-hole is equal to or longer than the outer peripheral length of the heater.

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). An increase in resistance can be prevented and the flavor or aerosol generated in the flavor generating article can be more reliably delivered to the user through this gap. It should be noted that the outer circumference of the heater here may be the maximum outer circumference of the portion of the heater that is inserted into the flavor generating article.

A nineteenth aspect is any one of the sixteenth to eighteenth aspects, wherein the heater is a plate-like heater having a first surface and a second surface facing the first surface, and the plate-like heater penetrates the The gist is that the elastically deformable sheet is deformed so that the distance between the elastically deformable sheet and the first surface or the second surface is reduced when inserted into the hole.

According to the 19th aspect, the elastically deformable sheet is deformed and contacts or approaches the first surface or the second surface of the heater, so that the flavor generating article can be efficiently heated.

A gist of a twentieth aspect is that in any one of the sixteenth to nineteenth aspects, the through-hole is defined by an inner surface of the elastically deformable sheet or the flavor generating sheet.

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

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 duplicate descriptions are omitted.

FIG. 1 is a schematic diagram of the flavor-generating article according to this embodiment. FIG. 2 is a side view of the flavor generating article taken along arrow 2-2 in FIG. In FIG. 1, the first portion 30 of the flavor generating article 10 is shown in cross-section and the second portion 20 is shown in side view. The flavor generating article 10 is a stick-shaped component as a whole, and is configured to generate 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 longitudinally adjacent to the first portion 30 .

The first portion 30 is configured to generate flavor by heating. As shown in FIGS. 1 and 2, the first portion 30 includes an elastically deformable sheet 32. As shown in FIG. Also, the second portion 20 is configured to allow the flavor generated in the first portion 30 to pass through. This allows the flavor produced in the first portion 30 to cool in the second portion 20 . The flavor-generating article 10 has a through-hole 36 into which a heater of a later-described flavor inhaler can be inserted. 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 (that is, the radial direction of the tubular elastically deformable sheet 32). As a result, when the heater is inserted into the through hole 36, the elastically deformable sheet 32 is elastically deformed in the thickness direction with respect to the heater, making it easier to contact or approach the heater. Therefore, when the elastically deformable sheet 32 contains flavor, or when a sheet containing flavor exists inside the elastically deformable sheet 32, the flavor-containing sheet can be brought into contact or closer to the heater. The flavor generating article 10 can be efficiently heated.

In the examples shown in FIGS. 1 and 2, the elastically deformable sheet 32 may be a non-tobacco sheet. A non-tobacco sheet means a non-tobacco material formed into a sheet, and may contain tobacco material. Specifically, the elastically deformable sheet 32 may be composed of non-tobacco fibers such as pulp fibers or non-woven fabrics, and may contain an aerosol source. Non-tobacco fibers used in non-tobacco sheets may include non-pulp fibers. Non-pulp fibers are fibers other than pulp fibers. Pulp fiber is an aggregate of cellulose fibers extracted from plants such as wood, and is usually used as a raw material for paper. Pulp fibers include waste paper pulp, chemical pulp, mechanical pulp and the like.

The non-tobacco sheet may contain a binder. A binder is an adhesive for binding fibers together. A binder known in the art can be used as the binder. The non-tobacco sheet may contain emulsifiers. Emulsifiers enhance the affinity between the aerosol-generating substrate, which is oleophilic, and the non-pulp fibers, which are hydrophilic. Known emulsifiers can be used, and examples thereof include emulsifiers having an HLB value of 8-18.

An aerosol source is a material that is vaporized by heating and then cooled to generate an aerosol, or that is atomized to generate an aerosol. Known aerosol sources can be used, and examples thereof include glycerin, polyhydric alcohols such as propylene glycol (PG), triethyl citrate (TEC), triacetin and the like. This aerosol source may also be added to the tobacco sheet 34b described below.

The non-tobacco sheet may contain a flavor generating base material. The flavor-generating substrate is a material that imparts flavor and taste, and is preferably a tobacco material. Specific tobacco materials include chopped dried tobacco leaves, pulverized leaf tobacco, tobacco extracts (extracts with water, organic solvents, or mixed solutions thereof), and the like. Leaf tobacco pulverized material is particles obtained by pulverizing leaf tobacco. The pulverized leaf tobacco can have, for example, an average particle size of 30 to 120 μm. Pulverization can be performed using a known pulverizer, and may be dry pulverization or wet pulverization. Leaf tobacco pulverized products are therefore also referred to as leaf tobacco particles. In the present embodiment, the average particle diameter is obtained by a laser diffraction/scattering method, and specifically measured using a laser diffraction particle size distribution analyzer (eg, Horiba LA-950). In addition, the type of tobacco is not limited, and yellow varieties, burley varieties, orient varieties, native varieties, and other Nicotiana tabacum varieties 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.

The flavor-generating base material may also contain a fragrance. A flavoring agent is a substance that provides an odor or flavor. The perfume may be a natural perfume or a synthetic perfume. As the perfume, one kind of perfume may be used, or a mixture of multiple kinds of perfumes may be used. Any flavor commonly used in smoking articles can be used as the flavor, specific examples of which are described below. The flavoring agent may be included in the non-tobacco sheet in an amount such that the smoking article can provide a desirable aroma or flavor, for example, the amount is preferably 1 to 30% by weight, more preferably 1 to 30% by weight of the non-tobacco sheet. is 10 to 20% by weight.

Any flavor that is commonly used, such as essential oils, natural flavors, and synthetic flavors, can be used as the flavor. Moreover, it may be liquid or solid, and its properties are not limited. Preferred flavors include tobacco extracts and tobacco components, carbohydrates and sugar flavors, liquorice, cocoa, chocolate, fruit juices and fruits, spices, western liquors, herbs, vanilla, and flower flavors. Flavors of choice, or combinations thereof. Specifically, isothiocyanates, indoles and their derivatives, ethers, esters, ketones, fatty acids, aliphatic higher alcohols, aliphatic higher aldehydes, aliphatic higher hydrocarbons, thioethers, Perfumes selected from thiols, terpene hydrocarbons, phenol ethers, phenols, furfural and derivatives thereof, aromatic alcohols, aromatic aldehydes, lactones, etc., or combinations thereof.

A cooling agent may be used alone or in combination of two or more.

The type of flavoring agent is not particularly limited, and from the viewpoint of imparting a good taste, for example, sweeteners (sugars (glucose, fructose, isomerized sugar, caramel, etc.)), acidulants (organic acids, etc.), and others. Flavoring agents (materials exhibiting umami, bitterness, salty taste, etc.) and the like. In addition, optionally, lipids (waxes, waxes, fatty acids (short-chain, medium-chain, long-chain fatty acids, etc.)) can be added.

When the cut tobacco contains a flavoring agent, a cooling agent, and a flavoring agent, the total content thereof is not particularly limited in one aspect, but from the viewpoint of imparting a good smoking taste, it is usually 10000 ppm or more, preferably It is 20,000 ppm or more, more preferably 25,000 ppm or more, and usually 70,000 ppm or less, preferably 50,000 ppm, more preferably 40,000 ppm or less, and still more preferably 33,000 ppm or less.

The elastically deformable sheet 32 preferably has a volume porosity of 85% or more and 95% or less. As a result, the flavor-containing sheet (elastic deformation sheet 32 or tobacco sheet 34b, which will be described later) can be appropriately brought into contact with or close to the heater. If the volume porosity of the elastically deformable sheet 32 is less than 85%, the repulsive force of the elastically deformable sheet is too strong, making it difficult to deform the flavor generating article. Moreover, in this case, there is a possibility that the ventilation resistance of the flavor-generating article may be excessively increased. When the volume porosity of the elastically deformable sheet 32 is more than 95%, the repulsive force of the elastically deformable 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 weak, resulting in delivery. may affect

In addition, the elastically deformable sheet 32 preferably has a ventilation resistance of 0 _mmH2O or more and ₁₅₀ mmH2O or less. As a result, even if there is no gap between the heater and the elastically deformable sheet 32, the ventilation resistance when the user inhales can be made appropriate. If the airflow resistance of the elastically deformable sheet 32 exceeds 150 mmH ₂ O, the suction resistance becomes too high, and the user may feel uncomfortable when sucking. The ventilation resistance of the elastically deformable sheet 32 here means the ventilation resistance in the longitudinal direction of the elastically deformable sheet 32, that is, in the left-right direction (air flow direction) in FIG.

The elastic deformation sheet 32 preferably 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 brought into close contact with each other to improve the heating efficiency.

The elastically deformable sheet 32 is preferably a non-tobacco sheet having a basis weight of 30 g/m ² or more and 100 g/m ² or less. As a result, the flavor-containing sheet can be brought into more appropriate contact with the heater. If the basis weight of the elastically deformable sheet 32 is less than 30 g/m ² , the flavor is quickly exhausted, or the elastically deformable sheet is too thin to easily break during the manufacturing process, resulting in poor production aptitude. Also, the elastically deformable sheet may break when the heater is inserted. If the basis weight of the elastically deformable sheet 32 exceeds 100 g/m ² , it becomes difficult to bend the elastically deformable sheet, making it difficult to deform the flavor generating article 10 . Moreover, in this case, since the heat capacity is increased, the temperature rise of the flavor generating article 10 is slowed down, and there is a possibility that it takes time until the first puff is possible.

As described above, the elastically deformable sheet 32 is preferably a non-tobacco sheet carrying an aerosol source or flavor-generating substrate. As a result, the elastically deformable sheet 32 is efficiently heated by contacting or approaching the heater, and aerosol or flavor can be generated.

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 positioned inside the elastically deformable sheet 32 , is formed in a tubular shape, and defines at least a portion of the through hole 36 together with the elastically deformable sheet 32 . As a result, the elastically deformable sheet 32 is deformed to contact or approach the heater, thereby allowing the flavor generating sheet 34 located inside the elastically deformable sheet 32 to contact or approach the heater. As a result, the flavor generating sheet 34 can be efficiently heated to generate an aerosol or flavor. Not limited to this, in the present embodiment, the through holes 36 may 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 come into direct contact with the heater 120, so that the elastically deformable sheet 32 or the flavor generating sheet 34 can be efficiently heated. obtain.

As shown in FIG. 2, the flavor generating sheet 34 can include a non-tobacco sheet 34a carrying an aerosol source or flavor generating substrate. As a result, the aerosol source or flavor-generating substrate of the non-tobacco sheet 34a can 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-described aerosol source or flavor-generating substrate that the elastically deformable sheet 32 can carry.

Also, as shown in FIG. 2, the flavor generating sheet 34 can include a tobacco sheet 34b. As a result, the tobacco sheet 34b can be efficiently heated to generate an 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 34a.

The tobacco sheet 34b may contain, for example, tobacco (corresponding to an example of a flavor-generating base material) and polyhydric alcohol (corresponding to an example of an aerosol source). Polyhydric alcohols may include glycerin, propylene glycol, sorbitol, xylitol and erythritol. These polyhydric alcohols can be used singly or in combination of two or more for the tobacco sheet 34b. These polyhydric alcohols can also be added to the elastically deformable sheet 32 described above. The tobacco sheet 34b can be formed into a sheet shape by mixing powdered tobacco and polyhydric alcohol with a binder. As the binder, for example, guar gum, xanthan gum, CMC (carboxymethylcellulose), CMC-Na (sodium salt of carboxymethylcellulose), pullulan and hydroxypropylcellulose (HPC), methylcellulose, hydroxylmethylcellulose and the like can be used. This binder can also be added to the elastically deformable sheet 32 described above.

Pulp may also be added to the tobacco sheet 34b. Pulp may improve the strength of the tobacco sheet 34b. On the other hand, the tobacco sheet 34b may be free of pulp. If pulp is not used, the percentage of tobacco in the tobacco sheet 34b is increased by that amount, so an improvement in smoking taste is expected.

The weight percentage 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 34b. The tobacco sheet 34b has a compounding ratio (weight percent) of, for example, 5% to 40% polyhydric alcohol, 50% to 90% tobacco, 0% to 10% binder, and 0% to 10% pulp. obtain. In addition, an acid such as lactic acid, palmitic acid, or benzoic acid may be added to the tobacco sheet 34b.

As shown in FIG. 2, the flavor generating sheet 34 can include a tobacco sheet 34b and a non-tobacco sheet 34a. However, the flavor-generating sheet 34 may include only one of the tobacco sheet 34b and the non-tobacco sheet 34a.

FIG. 3 is a cross-sectional view of the second portion 20 taken along line 3-3 shown in FIG. As shown in FIG. 3 , the second portion 20 has a tubular wrapping sheet 21 and a first stopper 22 located inside the wrapping sheet 21 . In the present embodiment, the basis weight of the wrapping sheet 21 is preferably 50 g/m ² or more and 150 g/m ² or less, more preferably 50 g/m ² or more and 100 g/m ² or less. The wrapping sheet 21 preferably surrounds the outside of the elastically deformable sheet 32 as shown in FIG. Specifically, the wrapping sheet 21 preferably extends from the second portion 20 to the first portion 30 . Thereby, the wrapping sheet 21 can maintain an appropriate shape against the deformation of the elastically deformable sheet 32 . If the basis weight of the wrapping sheet 21 is less than 50 g/m ² , it may deform more easily than the elastically deformable sheet 32 and may not maintain its proper shape. If the basis weight of the wrapping sheet 21 exceeds 100 g/m ² , the elastically deformable sheet 32 surrounded by the wrapping sheet 21 may be difficult to deform.

The first stopper 22 can prevent the elastic deformation sheet 32 from moving from the first portion 30 toward the second portion 20 . Specifically, in this embodiment, at least a portion of the first stopper 22 of the second portion 20 is positioned on the same radius as the elastically deformable sheet 32 when viewed in the longitudinal direction. In other words, at least part of the first stopper 22 is positioned to contact the elastically deformable sheet 32 in the longitudinal direction. As a result, when the heater is inserted into the through hole 36 , even if the heater applies force to the elastically deformable sheet 32 in the direction toward the second portion 20 , the first stopper 22 does not come into contact with the elastically deformable sheet 32 . , the movement of the elastically deformable sheet 32 can be prevented. Therefore, it is possible to prevent the flavor generating article 10 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. . Not limited to this, the first stopper 22 can take any form that can prevent the elastically deformable sheet 32 from moving from the first portion 30 toward the second portion 20 .

FIG. 4A is a side view of a flavor generating article 10 according to another embodiment. FIG. 4A shows a side view on arrow 2-2 shown in FIG. The flavor generating article 10 preferably has a second stopper 38 that prevents the elastically deformable sheet 32 from moving from the first portion 30 toward the opposite side of the second portion 20 . The second stopper 38 is positioned on the opposite side of the first portion 30 to the second portion 20, and at least a portion of the second stopper 38 is positioned on the same radius as the elastically deformable sheet 32 when viewed in the longitudinal direction. In other words, at least a portion of the second stopper 38 is positioned so as to contact the elastically deformable sheet 32 in the longitudinal direction at a position on the opposite side of the first portion 30 to the second portion 20 . This prevents the elastically deformable sheet 32 from moving toward the opposite side of the second portion 20 when the heater is removed from the through hole 36, that is, the elastically deformable sheet 32 is prevented from coming out of the first portion 30 together with the heater. can do. Therefore, even if the heater is pulled out from the through hole 36, the elastically deformable sheet 32 can remain in the first portion 30, so that the used flavor generating article 10 can be easily discarded.

In the example shown in FIG. 4A, the second stopper 38 is a sealing sheet that covers the end surface of the elastically deformable sheet 32 and the through hole 36 . Specifically, the second stopper 38 may extend in the radial direction of the first portion 30 of the flavor generating article 10 and may be formed with a perforation 38a substantially in the center thereof. FIG. 4B is a schematic illustration of the flavor generating article 10 after the heater has been inserted. In FIG. 4B, the first portion 30 is shown in cross-section. As shown in FIG. 4B, when the heater is inserted into the through hole 36, the second stopper 38 can be cut by the heater, for example along perforations 38a. By inserting the heater into the through hole 36 so as to break the second stopper 38 , the flavor generating article 10 can be heated by the heater while the second stopper 38 is positioned on the end surface of the elastically deformable sheet 32 . Therefore, when the heater is pulled out from the through-hole 36 after use, the second stopper 38 positioned at 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.

Next, the 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. As shown in FIG.

As shown in FIGS. The housing 110 has an opening 112 at one end and accommodates at least a portion of the flavor generating article 10 inserted into the opening 112 through the opening 112 . The housing 110 is, for example, made of resin, particularly PC (polycarbonate), ABS (Acrylonitrile-Butadiene-Styrene) resin, PEEK (polyetheretherketone), a polymer alloy containing a plurality of types of polymers, or the like, or It can be made of metal such as aluminum. Here, the housing 110 is configured such that the cross-sectional area of the cross section perpendicular to the longitudinal direction of the housing 110 is the smallest in the vicinity of the opening 112 .

The housing 110 also has a shaping guide 114 and a restraining 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 restraining ribs 116 are provided on the inner peripheral surface of the housing 110 and bias the flavor generating article 10 inserted into the housing 110 toward the heater 120 to deform the shape of the flavor generating article 10 . The detailed configuration of the shaping guides 114 and the restraining ribs 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 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. Also, 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 restraining rib 116, and the heater 120 deform the shape of the flavor generating article 10 after being housed in the housing 110 from the shape of the flavor generating article 10 before being housed in the housing 110. It is. Note that the heater 120 may be plate-shaped, and is not limited to the resistance heating type heater 120 as in the present embodiment.

Subsequently, when housing the flavor generating article 10 in the flavor inhaler 100, that is, when inserting the flavor generating article 10 from one end side of the housing 110 toward the other end side, the flavor generating article 10, the housing 110, and the heater 120 will be described. 7 to 9 are cross-sectional views showing how the flavor generating article 10 is accommodated in the flavor inhaler 100. FIG. 7 to 9 show the elastically deformable sheet 32 and the flavor generating sheet 34 of the flavor generating article 10 as one annular sheet 33. FIG.

FIG. 7 shows a state in which the flavor generating article 10 passes through the shaping guide 114 in 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 entrance portion 118 of the shaping guide 114. . FIG. 8 shows the state when the flavor-generating article 10 passes through the restraining rib 116 in a cross section in the width direction of the heater 120 and in the longitudinal direction of the housing 110 at the intermediate portion and the other end of the restraining rib 116. An orthogonal cross section is shown. FIG. 9 shows a state in which the flavor-generating article 10 is housed in a predetermined housing position in the housing 110, and shows a cross section in the width direction of the heater 120 and a longitudinal direction of the housing 110 in the vicinity of the other end of the heater 120. is shown for a cross section orthogonal to .

As shown in FIG. 7 , the shaping guide 114 has a tapered portion 117 and an entrance portion 118 . The tapered portion 117 is configured to expand toward one end of the housing 110 and guide the insertion of the flavor generating article 10 into the flavor inhaler 100 . Preferably, the maximum diameter of the opening 112 of the flavor inhaler 100 is greater than the maximum diameter of the flavor generating article 10 and the minimum diameter of the opening 112 is less than the minimum diameter of the flavor generating article 10 . In this case, by inserting the flavor generating article 10 into the opening 112 of the flavor inhaler 100 , the flavor generating article 10 can be deformed according to the shape of the opening 112 . Specifically, the flavor generating article 10 can be deformed to match the minimum diameter of the opening 112 to flatten its cross section. Thereby, the elastically deformable sheet 32 of the flavor generating article 10 contacts or approaches the heater 120, and the flavor generating article 10 can be efficiently heated. It should be noted that the opening 112 here may be a portion having the smallest cross-sectional area of the opening 112 of the flavor inhaler 100 into which the flavor generating article 10 is inserted. Specifically, the opening 112 here can be the inlet 118 in the example shown in FIG. The inlet portion 118 has an elliptical cross-section, a major axis larger than the diameter of the flavor generating article 10 after being accommodated in the housing 110, and a minor axis being larger than the flavor generating article 10 before being accommodated in the housing 110. may be configured to be approximately the same length as the diameter of the In addition, the inlet portion 118 may be configured such that the inner peripheral length is shorter than the outer peripheral length of the flavor generating article 10 .

As shown in FIG. 8, the heater 120 has a sharp shape and is configured so that its width increases toward the other end. Thereby, the shape of the flavor generating article 10 is deformed along the shape of the heater 120 as the flavor generating article 10 is inserted through the shaping guide 114 . Specifically, the heater 120 is a plate heater having a first surface 120a and a second surface 120b facing the first surface 120a. As shown in FIG. At this time, the elastically deformable sheet 32 is deformed such 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 contacts or approaches the first surface 120a or the second surface 120b of the heater 120, so that the flavor generating article 10 can be efficiently heated.

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 through hole 36 can be expanded by the heater 120 by inserting the heater 120 into the through hole 36 . Thereby, 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 flattened by the heater 120 , and the elastically deformable sheet 32 is deformed along the main surface of the plate-shaped heater 120 . can come in contact with or approach In addition, 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 adheres to the peripheral surface of the heater 120 . can touch or come close. Thereby, the flavor-generating article 10 can be efficiently heated. In addition, the heater 120 spreads the flavor-generating article 10, thereby preventing the flavor-generating article 10 from coming off.

The restraining 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). In addition, the restraining rib 116 is arranged so as to overlap the region where the width of the heater 120 gradually widens in the longitudinal direction of the housing 110 . Here, the restraining rib 116 is configured such that the protrusion distance gradually increases toward the other end side of the housing 110, and the protrusion distance is maximized at the position where the width of the heater 120 is maximized. It is 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, thereby generating the flavor. Article 10 is deformed into a flattened shape. In addition, the pressing rib 116 urges the flavor-generating article 10, thereby preventing the flavor-generating article 10 from coming off.

The inner peripheral length of the through hole 36 of the flavor generating article 10 is preferably equal to or longer than the outer peripheral length of the heater 120 . As a result, even if the flavor generating article 10 and the through hole 36 are deformed as shown in FIG. Therefore, an increase in suction resistance can be prevented, and the flavor or aerosol generated by the flavor generating article 10 can be more reliably delivered to the user through this gap.

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 on arrow 2-2 shown in FIG. The flavor-generating article 10 shown in FIG. 10 differs from the flavor-generating article 10 shown in FIGS. 1 and 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 wavy cross-section when viewed from the longitudinal direction. In the illustrated example, the elastically deformable sheet 32 can be elastically deformed in its thickness direction by deforming the corrugated cross section of the non-tobacco sheet. In addition, since the non-tobacco sheet with a corrugated cross section has gaps (between waves) along its longitudinal direction, it is possible to define channels through which the flavor and the like generated in the flavor generating article 10 pass. In the example shown in FIG. 10, the flavor generating sheet 34 has only the tobacco sheet 34b.
