Description

Flavor-carrying component for tobacco products and method for producing same

The present invention relates to a flavorant-carrying component for tobacco products and a manufacturing method thereof.

As a tobacco product containing a tobacco flavor source such as cut tobacco, a flavor inhaler that allows a user to taste the flavor by inhaling is known. Flavor inhalers can be broadly classified into combustion-type smoking systems typified by conventional cigarettes and heating-type smoking systems.

As an example of a heated smoking system, a heated flavor inhalation article (hereinafter also referred to as a heated cigarette) having a shape similar to that of a conventional cigarette and having a tobacco sheet and a filter has been developed. A desired flavor can be enjoyed by heating the heated cigarette with a separately prepared heating device. For example, Patent Literature 1 describes a heated smoking article having a tobacco portion, a filter portion, and a connection portion connecting these portions.

It is known that you can enjoy various flavors by adding flavorings to heated cigarettes. For example, in Patent Document 2, a step of extending a raw material slurry containing a polysaccharide containing at least one of carrageenan and gellan gum, a flavor, an emulsifier, and water on a substrate, a step of gelling the raw material slurry, and a gel a method for producing a flavor-containing sheet for smoking articles, comprising a heating and drying step comprising heating and drying the softened raw material at a sample temperature of 70 to 100°C. The sheet cuts obtained by this method are blended, for example, with shredded tobacco.

In addition, Patent Document 3 describes a heating type flavor inhaling article provided with a capsule containing a flavor.

Although the present invention will be described in detail below, the following description is intended to describe the present invention in detail and is not intended to limit the present invention.

<1. Flavorant-carrying constituent member>
The flavorant flavor-carrying component of the tobacco product comprises:
a tobacco product component;
and a flavor composition comprising an emulsifier having an HLB within the range of 1 to 7 and a flavoring agent carried by the component.

(tobacco products)
As used herein, a tobacco product is a flavor inhaler through which the user inhales the flavor. A flavor inhalation article is any inhalation article that includes a flavor source and from which a user inhales a flavor derived from the flavor source. The flavor source contained in the flavor inhalation article is preferably a tobacco flavor source. Flavor inhalation articles specifically include combustion-type smoking articles that provide the user with flavor by burning a flavor source, and heating-type flavor inhalation articles that provide the user with flavor by heating the flavor source without burning it. goods.

(Components of Tobacco Products)
A "tobacco product component" is a base member for carrying the flavorant composition. Therefore, in the following description, the constituent member of the tobacco product is also referred to as "base member".

The base member is, for example, a tobacco filler. Tobacco fillers are tobacco materials that function as tobacco flavor sources in tobacco products. The tobacco filler is, for example, an aggregate of shredded tobacco, an aggregate of sheet tobacco, an aggregate of cut tobacco sheets, an aggregate of tobacco granules, or a combination thereof. Tobacco shreds refer to cuts of tobacco leaf (dried tobacco leaves) ready for incorporation into tobacco products. Sheet tobacco refers to a tobacco product formed into a sheet from tobacco materials such as tobacco scraps and shredded tobacco produced in raw material factories and manufacturing factories such as leaf scraps and chopped tobacco. Tobacco granules refer to tobacco products formed into granules from tobacco materials such as tobacco scraps and shredded tobacco produced in raw material factories and manufacturing factories such as leaf scraps and cuts.

In this specification, when the base member is a tobacco filler, the flavorant-carrying constituent member is called a "flavorant-carrying tobacco filler". Specifically, when the base member is an aggregate of shredded tobacco, the flavorant-carrying constituent member is called "flavorant-carrying shredded tobacco", and when the base member is an aggregate of sheet tobacco or cut pieces of sheet tobacco. , the flavorant-carrying component is called a "flavorant-carrying sheet tobacco", and when the base member is an aggregate of tobacco granules, the flavorant-carrying component is called a "flavorant-carrying tobacco granule".

Alternatively, the base member may be cigarette paper. As used herein, when the base member is a cigarette paper, the flavorant-bearing component is referred to as a "flavorant-bearing cigarette paper."

Alternatively, the base member may be a filter. Specifically, the base member may be a filter medium (for example, an aggregate of cellulose acetate fibers, paper, or film) that constitutes the filter, or may be a plug wrapper wound around the filter medium. . The paper may or may not be crimped. As used herein, the flavorant-carrying component is referred to as a "flavorant-carrying filter" when the base member is a filter.

Alternatively, the base member may be a tube. The tube is obtained, for example, by rolling up paper. A tube made of paper, ie, a paper tube, will be described later. Herein, when the base member is a tube, the flavorant-carrying component is referred to as a "flavorant-carrying paper tube."

Alternatively, the base member may be the base material for the flavor filler. A flavor filler is a material in which a flavor is carried on a substrate such as a film or metal foil, and is used, for example, together with a tobacco filler in tobacco products. The flavorant filler may be used by laminating it to a member of the tobacco product. The base material of the flavorant filler does not contain tobacco material and serves to carry the flavorant. The base member may be a cut piece of the base material of the flavor filler.

The base material of the flavor filler is preferably metal foil. The metal foil may be a thin plate made of a composite metal material or a single metal material, or a metal foil composite made of a laminate of a metal material and other materials (eg, paper or film). Examples of thin plates made of composite metal materials or single metal materials include aluminum foil plates, copper foil plates, iron foil plates, and aluminum alloy foil plates. Further examples of metal foil composites include laminates of aluminum foil and paper, ie aluminum molded paper. Aluminum-laminated paper obtained by bonding aluminum foil to paper with an adhesive or aluminum-deposited paper obtained by vapor-depositing aluminum foil on paper is known as aluminum-molded paper.

When a metal foil is used as the base member, the metal has a high thermal conductivity, so that the flavorant composition supported on the metal foil is easily warmed during use of the tobacco product (especially during heating of the flavor inhalation article), and the flavor is enhanced. The release of flavorants contained in the food composition can be enhanced.

Alternatively, the base material of the flavor filler may be a film. The film may be organic or inorganic. The film may be, for example, a polymer film such as polyethylene terephthalate (PET) film. In addition, any material such as paper, sheet, non-woven fabric, etc., may have any composition or shape as long as it can support the flavoring composition. As used herein, the flavorant-carrying component is referred to as a "flavorant-carrying substrate" when the base member is the substrate for the flavorant filler.

(flavoring composition)
A "flavorant composition" comprises an emulsifier and a flavorant carried on a base member and having an HLB within the range of 1-7. The flavorant composition releases the flavorant upon heating or combustion of the flavor inhaling article. Alternatively, the flavorant composition releases the flavorant upon contact with vapor produced by heating the flavor inhalation article or smoke produced by combustion of the flavor inhalation article.

As used herein, HLB is measured by the Griffin method.
The emulsifier preferably has an HLB within the range of 2-5. Hereinafter, the emulsifiers described above are referred to as "low HLB emulsifiers".

The pulverized plant material is, according to yet another example, pulverized leaf tobacco. Leaf tobacco grinds are particles obtained by grinding leaf tobacco (ie, dried tobacco leaves used as a tobacco flavor source in tobacco products). The pulverized leaf tobacco has, for example, an average particle size of 0.1 μm to 120 μm. As used herein, the average particle diameter is determined by a laser diffraction/scattering method, and refers to a value measured using a laser diffraction particle size distribution analyzer (eg, Horiba LA-950).

Moreover, pectin etc. which are obtained from a fruit are mentioned as a plant-derived component. Plant-derived components also include cellulose, konjac mannan (glucomannan) containing agarose as a main component, and soybean polysaccharides obtained from other parts of plants. The guar gum may be cationized guar gum.

In addition, plant-derived components include carrageenan, which is obtained from seaweed and is classified into three types: kappa carrageenan, iota carrageenan, and lambda carrageenan, agar, and alginic acid. The carrageenan may be a carrageenan metal salt and the alginic acid may be a salt such as sodium alginate.

For example, plant-derived starches include corn starch, potato starch, sweet potato, and tapioca starch. These act as thickeners, stabilizers and the like. In addition, these starches can be crosslinked to improve acid resistance, heat resistance, shear resistance, and the like. In addition, it is possible to improve storage stability and promote gelatinization by esterification and etherification. In addition, it is possible to improve the transparency and storage stability by oxidation.

The plant-derived component is preferably tobacco extract.

Lipids are, for example, fatty acids or fatty acid esters.
When the flavorant composition further contains a fatty acid, irritation to the throat during use of the flavor inhalation article is likely to be suppressed. Also, when the flavor composition further comprises a fatty acid, the low HLB emulsifier emulsifies the fatty acid, allowing greater amounts of fatty acid to be incorporated into the flavor composition compared to a flavor composition that does not contain an emulsifier. .

The fatty acid is preferably saturated fatty acid. Also, the fatty acid is preferably a higher fatty acid. As used herein, higher fatty acids are fatty acids having 13 or more carbon atoms in one molecule.

Specific examples of fatty acids are palmitic acid, stearic acid, and myristic acid. Preferably, the fatty acid is palmitic acid. In addition, an unsaturated fatty acid may be sufficient as a fatty acid. In addition, one type of fatty acid may be used, or two or more types may be used. The fatty acid may also be a natural fat containing multiple fatty acids such as palm oil.

The mass of the fatty acid relative to the mass of the emulsifier is, for example, preferably within the range of 0.1 to 100.0, more preferably within the range of 1.0 to 10.0.

A fatty acid ester is, for example, a medium-chain fatty acid ester. Medium-chain fatty acid esters are, for example, medium-chain fatty acid triglycerides, medium-chain fatty acid diglycerides, or medium-chain fatty acid monoglycerides. Medium-chain fatty acids are, for example, caprylic acid, capric acid, or lauric acid having 8 to 12 carbon atoms. A specific example of the medium-chain fatty acid ester is tri(caprylic/capric)glyceryl or glyceryl trilaurate. Medium-chain fatty acid esters, for example, have a role in controlling the release of other flavorants. Medium-chain fatty acids can also be used to adjust the viscosity of the flavoring composition.

The flavoring agent may be of one kind, or two or more kinds.

The ratio M1/M2 between the mass M1 of the emulsifier and the mass M2 of the flavoring agent is preferably in the range of 0.001 to 20.0, more preferably in the range of 0.01 to 2.

The flavoring composition may further contain a solvent. A solvent is a solvent or dispersion medium for the flavorant. When the flavorant composition further contains a solvent, the flavorant composition is more likely to be supported on the tobacco constituent members because the affinity with the tobacco constituent members is further improved.

The solvent preferably contains a monohydric alcohol. Monohydric alcohols are, for example, ethanol or monohydric alcohols such as benzyl alcohol.

The weight of the solvent relative to the weight of the emulsifier is preferably in the range of 0.0 to 100, more preferably in the range of 0.1 to 20.

The flavoring composition may further contain glucan. Preferably, the glucan is an amphipathic glucan. Amphipathic glucans exhibit affinity for both hydrophobic and hydrophilic flavorants. Glucans are preferably soluble in organic solvents. Glucan is preferably a cellulose derivative, more preferably a cellulose derivative soluble in an organic solvent. Here, the cellulose derivative refers to a derivative obtained by introducing a substituent to the OH group of cellulose, and includes, for example, ethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose (e.g. hydrophobized hydroxypropyl methyl cellulose). In addition, cellulose derivatives are generally and widely used as binders, film-forming agents, and gelling agents due to the multiple effects brought about by their characteristic functional groups. Here, the organic solvent in the expression "soluble in an organic solvent..." is, for example, ethanol.

The cellulose derivative is preferably an amphipathic cellulose derivative, more preferably hydroxypropylcellulose. The degree of substitution of hydroxypropylcellulose is, for example, 0.1 to 4.5, preferably 2.0 to 4.5. As used herein, the degree of substitution of hydroxypropylcellulose refers to the number of hydroxypropyl groups per glucose. As hydroxypropyl cellulose, for example, one commercially available from Nippon Soda Co., Ltd. under the trade name of Cellny can be used.

The advantages of the flavoring composition further containing hydroxypropylcellulose are described below. Hydroxypropyl cellulose is a derivative of cellulose, and is a substance obtained by replacing the OH groups of cellulose with hydroxypropyl groups. Hydroxypropyl cellulose is widely used as a binder, filming agent and gelling agent. Cellulose is a hydrophobic substance because it crystallizes due to hydrogen bonding between OH groups between molecules. On the other hand, since hydroxypropyl cellulose has hydroxypropyl groups, it is difficult for hydrogen bonds to be formed between molecules, and it becomes a substance having both hydrophilicity and hydrophobicity (that is, an amphipathic substance).

In addition, it has been reported that hydroxypropyl cellulose forms a complex with a network structure in a system containing glycerin due to interactions (hydrogen bonds) between the hydroxypropyl groups of hydroxypropyl cellulose and the OH groups of glycerin. In addition, since hydroxypropyl cellulose has amphipathic properties, it is believed that hydrophilic flavoring agents and hydrophobic flavoring agents can be incorporated into the network structure. Due to this network structure composite, the flavoring agent is stably retained without volatilization during storage of the tobacco product, and stably released during use of the tobacco product (in particular, during heating of the flavor inhalation article). Conceivable. Moreover, when the flavoring composition further contains hydroxypropylcellulose, the viscosity of the flavoring composition can be adjusted well. The network structure formed by hydroxypropyl cellulose is smaller than that formed by the low HLB emulsifier. According to one example, the network formed by the hydroxypropyl cellulose is located inside the network of the network formed by the low HLB emulsifier. The network structure formed by the low HLB emulsifier will be described later. Hydroxypropyl cellulose is soluble in organic solvents, particularly ethanol.

The flavoring composition may further contain a coloring agent, a humectant, or a preservative.

Examples of coloring agents include natural pigments and synthetic pigments. Natural pigments include, for example, caramel, turmeric, red yeast, gardenia, safflower, carotene, marigold, and annatto. Synthetic pigments include, for example, tar pigments and titanium oxide.

Wetting agents include, for example, lipids such as waxes and waxes.

Examples of preservatives include benzoic acid, propionic acid, sorbic acid, salts thereof, and nisin.

For example, at 20°C, the flavoring composition is non-flowing. According to one example, the flavorant composition has solidified. Alternatively, the flavorant composition has a sufficiently high viscosity.

When the flavorant composition has a sufficiently high viscosity at 20°C, the viscosity of the flavorant composition is preferably 4000 mPa·s or more, more preferably 6000 mPa·s or more. When the flavorant composition has a sufficiently high viscosity, the flavorant composition is less likely to seep into the base member. Viscosity can be measured, for example, using a tuning fork vibration viscometer. Although there is no upper limit for the viscosity of the flavoring composition, the upper limit is, for example, 15000 mPa·s or less.

The freezing point of the flavoring composition is, for example, within the range of 20°C to 100°C.

For example, when the flavor composition is applied to the filter medium described above, the flavor composition preferably further contains an adsorbent. The adsorbent is, for example, a porous body such as activated carbon.

The flavoring composition may be present in the form of a coating on the surface of the base member so as to cover the entire surface of the base member, or may be present on the base member so as to cover a portion of the surface of the base member. may be present on the Also, the flavorant composition may be locally present on the surface of the base member (that is, present only on the surface of the base member and may not permeate the base member), or All of it does not necessarily exist on the surface of the base member, and a part of it may permeate the base member. For example, when an aggregate of cut pieces of sheet tobacco is used as the base member, the flavorant composition may be present in the gaps between the aggregates.

<2. Method for producing flavorant-carrying component>
The flavorant-carrying component described above can be produced, for example, by the following method.

First, prepare a mixture containing a low HLB emulsifier and a flavoring agent.

The mixture is then heated and stirred. Heating is performed within the range of 40° C. to 100° C., for example.
A flavor composition is obtained as described above.

The resulting flavorant composition is then applied to the tobacco product component.
The "constituent member of the tobacco product" is as described in the section "1. Flavor-carrying constituent member", and is also referred to as the "base member" in the following description.

The method of applying the flavoring composition to the base member is not particularly limited. For example, the flavor composition may be added or coated on the surface of the base member, the liquid composition may be sprayed onto the surface of the base member, or the base member may be mixed with the flavor composition. Alternatively, the flavorant composition may be injected directly into the portion of the base member in the tobacco rod by an injector or the like. When the flavorant composition is directly injected into the base member portion of the tobacco rod using an injector or the like, the flavorant composition may be directly injected, for example, into holes of the tobacco filler 111, which will be described later. Alternatively, the flavorant composition may be injected directly into the tobacco filler 111 without providing the above holes.

When the flavoring composition is applied to the cut tobacco, the flavoring composition is added directly to the cut tobacco surface by a transfer pump, sprayed onto the cut tobacco by a nozzle atomizer, or added to the cut tobacco in the tobacco rod by an injector or the like. A method of directly injecting into the part can be adopted. Alternatively, the application of the flavoring composition to the cut tobacco may involve immersing the cut tobacco in the flavoring composition.

When applying a flavoring composition to a sheet tobacco, a method of extruding and adding it to the surface of the sheet tobacco using a slit feeder, or a method of coating with a film applicator or the like can be adopted. Alternatively, techniques such as spraying and immersion can be employed following the same technique applied to cut tobacco. If sheet tobacco is cut, it is preferable to follow the same procedure as applied to shredded tobacco.

When applying the flavoring composition to the cigarette paper, as described above, it is possible to adopt a method of extrusion addition using a slit feeder or a method of coating using a film applicator. Alternatively, techniques such as spraying and immersion can be employed following the same technique applied to cut tobacco.

When applying the flavoring composition to tobacco granules, a granule coating technique can be used. For example, the method of adding the flavoring composition directly to the surface of the tobacco granules can be adopted according to the same method as applied to cut tobacco.

When applying a flavoring composition to a filter medium such as cellulose acetate fiber, following the same method as applying to shredded tobacco, a method of extruding with a slit feeder or a method of coating with a film applicator can be adopted. Alternatively, techniques such as spraying and dipping can be employed following the same technique as applied to cut tobacco.

When applying the flavoring composition to a filter medium such as paper or film, for example, a method of coating with a film applicator or the like can be adopted according to the same method as that applied to sheet tobacco. Alternatively, techniques such as spraying and immersion can be employed following the same technique applied to cut tobacco.

The amount of the flavoring composition applied is appropriately determined according to the composition of the flavoring composition (types and amounts of ingredients), the type of the base member, etc., so that the flavoring-carrying component can provide the flavoring. can decide.

When the flavor composition is directly injected into the base member, for example, an aggregate of sheet tobacco shreds using an injector or the like, the applied amount of the flavor composition is preferably 100 parts by mass of the aggregate of sheet tobacco shreds. It is in the range of 1.0 to 50.0 parts by weight relative to the body.

When the flavorant composition is applied to the filter medium, the applied amount of the flavorant composition is preferably in the range of 1.0 parts by weight to 80.0 parts by weight per 100 parts by weight of the filter medium.
As described above, the flavorant-carrying constituent member of the tobacco product is obtained.

According to the method for producing the flavorant-carrying component described above, the flavorant-carrying component can be produced without going through the drying process. That is, the flavorant-carrying constituent member can be produced without going through the heat drying process or the vacuum drying process. Therefore, when the flavoring composition contains a volatile component, volatilization of the volatile component is suppressed. Here, the heat-drying step is a step performed within a range of 40° C. to 200° C., for example.

An example of a heated flavor inhalation article will be described below.
FIG. 1 is a schematic diagram schematically showing a heated flavor inhalation article 1 according to one embodiment of the present invention. The heated flavor inhalation article 1 shown in FIG. 1 comprises a flavorant-carrying tobacco filler.

The heating type flavor inhaling article 1 (hereinafter simply referred to as "flavor inhaling article 1") has a cylindrical shape. The length of the circumference of the flavor inhaling article 1 is preferably 16 mm to 27 mm, more preferably 20 mm to 26 mm, even more preferably 21 mm to 25 mm. The total length (horizontal length) of the flavor inhaling article 1 is not particularly limited, but is preferably 40 mm to 90 mm, more preferably 50 mm to 75 mm, and even more preferably 50 mm to 60 mm.

The flavor inhaling article 1 includes a tobacco-containing segment 11, a filter portion 12 forming a mouthpiece, a connecting portion 13 connecting the tobacco-containing segment 11 and the filter portion 12, and a lining paper . These will be described below with reference to FIG.

FIG. 2 is a cross-sectional view schematically showing the flavor inhaling article 1 shown in FIG.

The tobacco-containing segment 11 has a cylindrical shape. The total length (axial length) of the tobacco-containing segment 11 is, for example, preferably 20 to 70 mm, more preferably 20 to 50 mm, even more preferably 20 to 30 mm. The cross-sectional shape of the tobacco-containing segment 11 is not particularly limited, but may be circular, elliptical, polygonal, or the like, for example.

The tobacco-containing segment 11 has a tobacco filler 111 , a cigarette paper 112 wrapped around the tobacco filler 111 , and a flavoring composition 113 .

The tobacco filler 111 is, for example, an aggregate of cut pieces of sheet tobacco. The tobacco filler 111 is a columnar body. For example, as shown in FIG. 1, tobacco filler 111 is cylindrical. The tobacco filler 111 has holes extending from one bottom surface to the other bottom surface. In FIG. 2, this hole is a through hole.

The tobacco filler 111 may contain an aerosol-generating base material. Aerosol-forming substrates include glycerin, propylene glycol (PG), triethyl citrate (TEC), triacetin, 1,3-butanediol, and the like. These may be used alone or in combination of two or more.

The cigarette wrapping paper 112 is wrapping paper for wrapping the tobacco filling material 111 in the flavor inhaling article.

The flavoring composition 113 is positioned inside the pores of the tobacco filler 111 . The flavorant composition 113 is located primarily within the pores, but may diffuse into areas near the pores or may diffuse throughout the tobacco filler 111 .

The filter part 12 has a cylindrical shape. The filter part 12 has a rod-shaped first segment 121 , a rod-shaped second segment 122 , and an outer plug wrapper 123 .

The first segment 121 is located on the tobacco-containing segment 11 side. The first segment 121 has a through hole extending from one bottom surface to the other bottom surface. The second segment 122 is located on the mouthpiece side. Second segment 122 is solid. The first segment 121 is composed of a first filler (cellulose acetate fiber) 1211 and an inner plug wrapper 1212 wound around the first filler 1211 . The second segment 122 is composed of a second filler (cellulose acetate fiber) 1221 and an inner plug wrapper 1222 wound around the second filler 1221 .

The outer plug wrapper 123 connects the first segment 121 and the second segment 122 . The outer plug wrapper 123 is adhered to the first segment 121 and the second segment 122 with a vinyl acetate emulsion adhesive or the like.

The length of the filter part 12 is, for example, 10 to 30 mm, the length of the connecting part 13 is, for example, 10 to 30 mm, the length of the first segment 121 is, for example, 5 to 15 mm, and the length of the second segment 122 is, for example, 5 to 15 mm. can do. The length of each of these segments is an example, and can be changed as appropriate according to manufacturing aptitude, required quality, length of the tobacco-containing segment 11, and the like.

For example, the first segment 121 (center hole segment) is composed of a first filling body 1211 having one or more through-holes and an inner plug wrapper 1212 covering the first filling body 1211 . The first segment 121 has the function of increasing the strength of the second segment 122 . The first filler 1211 of the first segment 121 is, for example, a filler filled with cellulose acetate fibers at a high density. A plasticizer containing triacetin is added to the cellulose acetate fibers in an amount of, for example, 6 to 20% by mass based on the mass of the cellulose acetate, and hardened. The through hole of the first segment 121 has an inner diameter of φ1.0 to φ5.0 mm, for example.

The first packing 1211 of the first segment 121 may, for example, be configured with a relatively high fiber packing density, or have a fiber packing density equivalent to that of the second packing 1221 of the second segment 122, which will be described later. may Therefore, air and aerosol flow only through the through-holes during suction, and hardly any air or aerosol flows through the first filling member 1211 . For example, in the second segment 122, when it is desired to reduce the reduction of the aerosol component due to filtration, for example, the length of the second segment 122 can be shortened and the first segment 121 can be lengthened accordingly.

Replacing the shortened second segment 122 with the first segment 121 is effective for increasing the delivery amount of the aerosol component. Since the first filler 1211 of the first segment 121 is a fiber filler, the feeling of touch from the outside during use does not make the user feel uncomfortable.

The second segment 122 is composed of a second filling body 1221 and an inner plug wrapper 1222 covering the second filling body 1221. The second filler 1221 of the second segment 122 is, for example, a filler filled with cellulose acetate fibers. The second segment 122 (filter segment) is packed with cellulose acetate fibers at a typical density and has typical aerosol component filtration performance.

The first segment 121 and the second segment 122 may have different filtration performances for filtering the aerosol (mainstream smoke) emitted from the tobacco-containing segment 11 . At least one of the first segment 121 and the second segment 122 may contain a flavoring agent. The structure of the filter part 12 is arbitrary, and may be a structure having a plurality of segments as described above, or may be composed of a single segment.

The connecting part 13 has a cylindrical shape. The connecting portion 13 has a cylindrical paper tube 131 made of, for example, thick paper.

As described above, the lining paper 14 is cylindrically wound around the tobacco-containing segment 11, the connecting portion 13, and the filter portion 12 to integrally connect them. One surface (inner surface) of the lining paper 14 is coated with a vinyl acetate emulsion-based adhesive over the entire surface or substantially the entire surface except for the vicinity of the air holes 141 . After the tobacco-containing segment 11, the connecting portion 13, and the filter portion 12 are integrated with the lining paper 14, the plurality of vent holes 141 are formed by laser processing from the outside.

The air hole portion 141 has two or more through holes so as to pass through the connecting portion 13 in the thickness direction. The two or more through-holes are formed so as to be radially arranged when viewed from the extension of the central axis of the flavor inhaling article 1 . In the present embodiment, the ventilation hole portion 141 is provided in the connecting portion 13 , but may be provided in the filter portion 12 . Further, in the present embodiment, the two or more through holes of the ventilation hole portion 141 are arranged in a row on one circular ring at regular intervals. Alternatively, one or two rows of vent holes 141 may be arranged discontinuously or irregularly. Outside air is taken into the mainstream smoke through the ventilation hole portion 141 when the user sucks with the mouthpiece.

Note that the first segment 121 may be omitted. When the first segment 121 is omitted, the length of the second segment 122 may match the length of the filter section 12 . In this case, a seamless capsule containing a flavoring agent may be provided in the second filling body 1221 .

Also, the above-mentioned holes that the tobacco filler 111 has may be omitted. In this case, the flavorant composition is located, for example, in the interstices of the tobacco filler 111 .

Further, the above-described flavor inhaling article 1 includes a flavorant-carrying tobacco filler, but instead of the flavorant-carrying tobacco filler, the above-mentioned flavorant-carrying filter or the above-mentioned flavorant-carrying paper tube is provided. good too. According to one example, the flavorant-carrying filter includes a first filling body 1211 and a flavorant composition carried on the sidewalls of the through holes of the first filling body 1211 . The flavorant-carrying filter, according to another example, includes a second packing 1221 and a flavorant composition carried by the second packing 1221 . The flavorant-carrying paper tube includes, for example, a paper tube 131 and a flavorant composition carried on the inner surface of the paper tube 131 .

An example of a heating type flavor sucking article has been described above.

The flavor inhaling article 1 described above may be heated by a heating device separate from the article, or may be heated by a heating device integrated with the article.

<effect>
By the way, a flavor composition which is the same as the flavor composition described above except that it does not contain a low HLB emulsifier (hereinafter referred to as a flavor composition according to a comparative example) has fluidity. Therefore, when the flavorant composition according to the comparative example is applied to the component parts of tobacco products, the flavorant composition tends to seep out to the component parts.

On the other hand, since the flavor composition described above contains a low HLB emulsifier, it is non-flowable at room temperature, for example, 22°C. For this reason, when the flavorant composition described above is applied to the constituent members of tobacco products, the flavorant composition, specifically, the liquid component of the flavorant composition, is less likely to seep out into the constituent members. The present inventors believe that one of the reasons why the flavoring composition is non-flowing is as follows. Low HLB emulsifiers form a network in the flavor composition. This network structure has relatively large meshes, for example meshes with a maximum mesh diameter of several microns, and is believed to retain the components of the flavor composition other than the low HLB emulsifier within this meshwork. For this reason, the flavorant composition described above is non-fluid and does not easily ooze out into the constituent members of the tobacco product.

In addition, the present inventors found that the flavor inhalation article containing the flavorant composition according to the comparative example sometimes reduced the amount of flavorant released depending on the number of puffs during inhalation. One of the reasons why the release amount of the flavoring agent is decreased is considered as follows. When the flavorant composition has flowability, the flavorant composition spreads over the components of the tobacco product and has a large contact area with fluid such as air. Accordingly, the flavorant contained in the flavorant composition is likely to be released into fluids such as air. Therefore, much of the flavoring agent is released at a low number of puffs. Thus, the amount of flavoring agent released decreases with the number of puffs.

On the other hand, with the flavor sucking article containing the flavor composition described above, the release amount of the flavor according to the number of puffs is less likely to decrease during sucking. That is, the flavor inhaling article containing the above-described flavorant composition shows little change in the amount of flavorant released depending on the number of puffs. One of the reasons why the change in the release amount of the flavoring agent is small is considered to be as follows. The flavor composition described above is non-flowing. Therefore, the flavorant composition described above does not spread over the constituent members of the tobacco product and has a small contact area with fluid such as air, as compared with the flavorant composition according to the comparative example. In addition, in the flavor composition described above, the flavor is held in the network structure described above. For these reasons, the flavoring agent contained in the flavoring composition described above is less likely to be released into a fluid such as air as compared with the flavoring composition according to the comparative example. Therefore, the flavor inhalation article containing the above-described flavorant composition shows little change in the amount of flavorant released depending on the number of puffs.
