[Embodiment]
An embodiment of a cigarette which is an example of a smoking article will be described. A smoking article (e-cigarette) that can inhale the flavor of tobacco by heating the tobacco with cigarettes, cigars, hand-rolled cigarettes, cigarillos, heaters, etc. or steaming the tobacco with steam is included in smoking articles, The smoking device which can inhale the flavor of tobacco by heating tobacco by a carbon heat source etc., the smoking device which can inhale the flavor of tobacco by a non-heating type, etc. are included.

As shown in FIGS. 1 and 2, the cigarette 11 is adjacent to an aerosol generating rod 14 comprising a tobacco cut 12 (cut leaf, tobacco) and a paper roll 13 wrapped around the tobacco cut 12 and an aerosol generating rod 14 And a tip paper member 16 wound on the aerosol generating rod 14 and the filter unit 15 so as to connect them across the aerosol generating rod 14 and the filter unit 15. In the cigarette 11, a central axis C passing through the center of the aerosol generating rod 14 and the center of the filter portion 15 can be defined.

The filter unit 15 is embedded in the cylindrical filter body 17, the filter wrapping paper 21 wound around the filter body 17, and the filter unit 15 (in the filter body 17). And a capsule member 23 for holding a content liquid containing a perfume, and an adhesive 24 for bonding the filter body 17 and the capsule member 23 together.

The tipping paper member 16 wrapping the filter unit 15 may or may not have a plurality of vents in a part of its outer periphery. When vents are provided, the number of vents may be, for example, 10 to 40. In that case, the plurality of air vents are arranged in an annular shape, for example, in a row on the outer peripheral portion of the tip paper member 16 packaging the filter unit 15. The plurality of air vents are formed at substantially constant intervals. By providing a plurality of vents, air is taken into the filter portion 15 from the vents when smoking. By diluting the mainstream smoke with air from the air, product design of the desired tar value is possible.

As shown in FIG. 2, the cigarette 11 straddles the tobacco cut 12 and the aerosol generation rod 14 including the wrapping paper 13 wound around the tobacco cut 12, the filter portion 15, the aerosol generation rod 14 and the filter portion 15. And a tipping paper member 16 wound on the aerosol generating rod 14 and the filter unit 15 so as to connect them.

The capsule member 23 is embedded in the filter body 17. One capsule member 23 may be present in the filter unit 15 or a plurality of (for example, 2 to 10) capsule members may be present. The capsule member 23 is provided on the central axis C of the filter unit 15 or in the vicinity of the central axis C. The capsule member 23 is positioned closer to the suction end 26 than the position moved 15 mm in the central axis C direction from the suction end 26 of the filter portion 15 toward the aerosol generating rod 14 or the position moved 15 mm. More preferably, the capsule member 23 is positioned closer to the suction end 26 than a position moved 10 mm in the central axis C direction from the suction end 26 of the filter unit 15 toward the aerosol generating rod 14. More preferably, the capsule member 23 is positioned closer to the suction end 26 than a position moved 7 mm in the central axis C direction from the suction end 26 of the filter unit 15 toward the aerosol generating rod 14. With such an arrangement, the user not only crushes the capsule member 23 with a finger but also easily crushes the capsule member 23 even when biting by teeth during smoking, and the flavor generation source sucks The closer to the end, the smoker can enjoy a stronger flavor.

The capsule member 23 is composed of a film 22 and a content liquid contained in the film 22 and containing a fragrance. For example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride and the like can be used for the film 22, and further, a flavor and a coloring agent can be included. Even if the capsule member 23 is surrounded by the opaque filter wrapping paper 21 or the tip paper member 16, it is preferable that the capsule member 23 be colored so that the smoker can recognize it when crushing the capsule member 23. For example, it is preferable to include Blue No. 1 and the like. When the film 22 of the capsule member 23 contains a hydrophilic material, it can be said that the film 22 is made of a material that is weakened by water absorption.

As a flavor of the content liquid, any flavor used for smoking articles such as menthol and plant essential oil can be used, for example. Main flavors include menthol, leaf tobacco extract, natural vegetable flavors (eg, cinnamon, sage, herbs, chamomile, vermicelli, sweet tea, clove, clove, lavender, cardamom, scallops, nutmeg, bergamot, geranium, honey essence, rose Oil, lemon, orange, silk peel, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang ylang, fennel, anise, licorice, st john's bread , Plum extract, peach extract, etc., sugars (eg, glucose, fructose, isomerized sugar, caramel etc.), cocoas (powder, extract etc.), esters (eg, isoamyl acetate, linalyl acetate, propi Isoamyl acid (linalyl butyrate etc.), ketones (eg menthol, ionone, damascenone, ethylmaltool etc.), alcohols (eg geraniol, linalool, anethole etc.), aldehydes (eg vanillin, benzaldehyde, anis) Aldehydes, etc.), lactones (eg, γ-undecalactone, γ-nonalactone etc.), animal flavors (eg, musk, ambergris, civette, custrium etc.), hydrocarbons (eg, limonene, pinene etc.) It can be mentioned. These flavors may be used alone or in combination.

As a solvent for the content liquid, a solvent suitable for a perfume can be used, and medium-chain fatty acid triglyceride (MCT) (specifically, tricapryl / glyceryl caprate), propylene glycol, water, ethanol or the like can be used. . The content liquid may further contain other additives such as other solvents, dyes, emulsifiers and thickeners.

Although the manufacturing method of the capsule member 23 is not particularly limited, the capsule member 23 having the seamless film 22 can be manufactured by using, for example, a dropping method. In this method, the coating liquid can wrap the content liquid without having a joint by simultaneously discharging the content liquid from the inner nozzle and the liquid coating material from the outer nozzle using the double nozzle.

Capsule member 23 may have, for example, the shape of a sphere or a cylinder, where the sphere includes both a sphere having a substantially circular cross section and an ellipsoid having an oval cross section. Capsule member 23 preferably has the shape of a sphere whose cross section is substantially circular. The capsule member 23 may have, for example, a diameter of 1.0 to 8.0 mm in the case of a sphere having a substantially circular cross section, and may have, for example, a maximum diameter of 2.0 to 8.0 mm and a minimum diameter of 1. In the case of a cylindrical body, the diameter of a circle can be 1.0 to 8.0 mm and the height can be 1.0 to 8.0 mm. When applying a spherical capsule member to a generally circulating cigarette, a capsule having a diameter smaller than 7.5 to 8.0 mm, which is the diameter of a generally circulating cigarette and filter section, should be used It is. When applying a spherical capsule member to a cigarette in general circulation, it is preferable to use a capsule member having a diameter of 3.0 mm to 4.5 mm. If the diameter of the capsule is too small, the amount of flavoring applied to the cigarette will be small and the feeling of satisfaction that can be given by the flavoring will be less, and the smoker will find the presence of the capsule when shredding the capsule Difficulty, etc. are mentioned as problems. If the diameter of the capsule is too large, the ratio of the cross-sectional area of the capsule to the cross-sectional area of the filter body will be large, so the air flow resistance of the filter part at the time of non-crushing of the capsule becomes too large. It makes me feel.

The filter body 17 may be constituted by a filter medium of cellulose acetate fiber bundle (acetate tow), as in a conventional filter cigarette. The filter body 17 may be composed only of acetate tow filter media, or may be composed of an acetate tow filter media and a filter wrapping paper 21 wound around it. When the filter unit 15 includes a plurality of filter bodies 17, the filter body 17 on the side of the tobacco cut 12 and the filter body 17 on the inlet side may have the same material and structure, or have different materials and structures. It may be

For example, acetate tow has a single yarn fineness of 1.9 to 12.0 (g / 9000 m), a total fineness of 10000 to 44000 (g / 9000 m), a number of fibers of 830 to 23500 (pieces), and a ventilation resistance of 100 to 600 (mm H2O / 120 mm). The single yarn fineness, the total fineness, and the number of fibers should be designed to achieve the target value of air flow resistance according to the set circumference (14.0 to 26.0 (mm)) of the filter body . A plasticizer such as triacetin may be added to the acetate tow, and the plasticizer may be added in an amount of 5 to 12% by weight based on the weight of the acetate tow, dispersing the activated carbon between the fibers of the acetate tow When added, the plasticizer can be added in an amount of 2 to 12% by weight based on the weight of acetate tow.

The filter portion 15 has, for example, a circumference of about 14 to 26 mm, and the length may be, for example, 17 to 40 mm as in a conventional filter.

The aerosol generating rod 14 consists of a tobacco cut 12 and a cigarette paper 13 wound around the same as a normal cigarette 11, and can have a circumference of about 14 to 26 mm and a length of 20 to 70 mm, for example. .

The adhesive 24 is provided over the entire length of the filter portion 15 in the longitudinal direction (the direction of the central axis C). The adhesive 24 is provided in a line along the central axis C of the filter portion 15 on or near the central axis C of the filter portion 15. Since the capsule member 23 is also located on or near the central axis C, a part of the adhesive 24 is located within the projected cross section in the central axis C direction of the capsule member 23. The adhesive 24 bonds the capsule member 23 and the filter main body 17 which are also located on the central axis C.

The adhesive 24 is partially arranged in an arc shape along the outer shape of the capsule member 23. The adhesive 24 is made of a thermoplastic resin (hot melt adhesive). When the adhesive 24 is applied to the inside of the filter unit 15, the adhesive 24 is liquefied by raising the temperature to 100 to 200.degree. However, at the time of product shipment, the adhesive 24 is completely solid. In the production line of the filter unit 15, the adhesive 24 is continuously and linearly applied to the filter tow at a rate of 10 to 50 mg per 120 mm in the longitudinal direction of the filter body 17. As shown in FIG. 3, the adhesive 24 may cover, for example, 1/20 to 1/3 of the total surface area of the capsule member 23. On the other hand, it is desirable that the area covering the surface of the capsule member 23 be, for example, 1/2 or less. If half or more of the surface area of the capsule member 23 is covered with the adhesive 24, the adhesive 24 functions as a kind of coating, so the capsule member 23 becomes too hard and it is difficult to break it with a finger. Become.

A perfume may be uniformly added to the adhesive 24. It is considered that a suitable amount of the flavoring agent when uniformly including these flavoring ingredients in the adhesive 24 is an amount that does not cause deterioration of the function of the adhesive 24. The amount of the flavor to be uniformly contained in the adhesive 24 can be appropriately adjusted, for example, by increasing or decreasing the amount to fragrant the mainstream smoke of the cigarette 11 (smoking article).

These flavor components may be directly dispersed in the adhesive 24, or these flavor components may be included in a clathrate such as dextrin, α-cyclodextrin, β-cyclodextrin and then the adhesive 24. It may be dispersed inside. By taking such a method, by dispersing in the adhesive 24, the influence on the adhesive strength of the adhesive 24 can also be reduced.

Examples of perfumes added to the adhesive 24 include the following. For example, acetoanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, trans-anethole, star anise oil, apple juice, peru balsam oil, beeswax absolute, benzaldehyde, benzoin resinoid, benzyl alcohol , Benzyl benzoate, benzyl phenylacetate, benzyl propionate, 2,3-butanedione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamom oil, carob abrolith, β-carotene, carrot juice, L-carvone, β- Caryophyllene, cassia bark oil, cedarwood oil, celery seed oil, camomile oil, cinnamaldehyde, cinnamic acid, cinnamyl alcohol, cinnamic acid cinnamic acid, citrone La oil, DL-syntonello, clary sage extract, cocoa, coffee, cognac oil, coriander oil, cumin aldehyde, davana oil, δ-decalactone, γ-decalactone, decanoic acid, dill herb oil, 3,4-dimethyl-1, 2-Cyclopentadione, 4,5-dimethyl-3-hydroxy-2,6-dihydrofuran-2-one, 3,7-dimethyl-6-octenoic acid, 2,3-dimethylpyrazine, 2,5-dimethyl Pyrazine, 2,6-dimethylpyrazine, ethyl 2-methylbutyrate, ethyl acetate, ethylbutyrate, ethylhexanoate, ethylisovalerate, ethyl lactate, ethyl laurate, ethyl levulinate, ethyl maltol, ethyl octanoate, oleic acid Ethyl, ethyl palmitate, ethyl phenylacetate, ethyl propionate, Ethyl tea phosphate, ethyl valerate, ethyl vanillin, ethyl vanillin glucoside, 2-ethyl-3, (5 or 6) -dimethylpyrazine, 5-methyl-3-hydroxy-4-methyl-2 (5H) -furanone, 2 -Ethyl-3-methylpyrazine, eucalyptol, phenegrig absolut, gene absolut, gentian root infusion, geraniol, geranyl acetate, grape juice, guaiacol, guarba extract, γ-heptalactone, γ-hexalactone, hexane Acid, cis-3-hexan-1-ol, hexyl acetate, hexyl alcohol, hexyl phenyl acetate, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4- (3-hydroxy-1-butenyl)- 3,5,5-Trimethyl-2-cycle Rohexan-1-one, 4- (para-hydroxyphenyl) -2-butanone, sodium 4-hydroxyundecanoate, immortal absolute, β-ionone, isoamyl acetate, isoamyl butyrate, isoamyl phenyl acetate, isobutyl acetate, phenyl Isobutyl acetate, Jasmine absolute, Coconut tincture, Rapdanum oil, Lemon terpeneless oil, licorice extract, linalool, linal acetate, Ropard root oil, maltol, maple syrup, menthol (L-menthol), menthone, L-menthyl acetate, Paramethoxybenzaldehyde, methyl-2-pyrrolyl ketone, methyl anthranilate, methyl phenylacetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methyl Herbaceous acid, Mimosa abroliut, corn flour, myristic acid, nerol, nerolidol, γ-nonalactone, nutmeg oil, δ-octalactone, octanal acid, octanoic acid, orange flower oil, orange oil, oris oil, palmitic acid, peppermint oil, Puri Grain paraguay oil, phenethyl alcohol, phenylacetic acid phenethyl, phenylacetic acid, piperonal, plum extract, propenyl guaitol, propyl acetate, 3-propylidenephthalide, prune fruit juice, pyruvate, raisin extract, rose oil, rum wine , Sage oil, sandalwood oil, spearmint oil, stylux absolute, marigold oil, di-di-stearate, α-terpineol, terpinyl acetate, 5,6,7,8-tetrahydroxaline, 1,1,7 5,5,9-Tetramethyl-13-oxachloro (8.3.0.0 (4.9)) tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil, tomato extract, 2-tridecanone Trimethyl citrate, 4- (2,6,6-trimethyl-1,3-cyclohexenyl) 2-buten-4-one, 2,6,6-trimethyl-2-cyclohexene-1,4-dione, 4 -(2,6,6-Trimethyl-1, 3-cyclohexadienyl) 2-buten-4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin There is a petratol aldehyde, violet leaf absolute.

These flavors may be used alone or in combination of two or more to achieve the desired flavor.

The perfume dispersed in the adhesive 24 is fixed in the adhesive 24 before smoking and almost no volatilization out of the adhesive 24 occurs. On the other hand, when smoking, mainstream smoke passes near the adhesive 24. The heat of the mainstream smoke and / or the moisture (vapor) contained in the mainstream smoke volatilizes the fragrance fixed in the adhesive 24 into the mainstream smoke. By this, a gap can be provided between the smell of the cigarette 11 (smoking article) before smoking and the smell of mainstream smoke at the time of smoking, which can give a surprise to the smoker. In addition, it is necessary that a predetermined time is required from the start of smoking until the fragrance fixed in the adhesive 24 evaporates into the mainstream smoke, that is, the fragrance fixed to the adhesive 24 enters the mainstream smoke from the start of smoking It is also possible to give a time lag before volatilization.

The adhesive 24 can be uniformly mixed with a dye such as a dye or a pigment. As such a pigment, for example, a food pigment can be used. Examples of food dyes include, for example, natural pigments such as gardenia yellow pigment, annatto pigment, red pepper pigment, red cabbage pigment, white locust pigment, gardenia blue pigment, food red 2, food red 3, food red 102, food red 102, Food dyes such as food red 104, food red 105, food yellow 4, food yellow 5, food blue 1, food blue 2, etc. may be mentioned.

The operation of the cigarette 11 of the present embodiment will be described. In the cigarette 11 of the present embodiment, the tip of the aerosol generating rod 14 is ignited, the mouth end 26 of the filter unit 15 is held by the mouth, and the user can enjoy the flavor and taste of the cigarette. At that time, the main stream smoke is mixed with a flavor contained in the content liquid of the capsule member 23 or a flavor volatilized from the adhesive 24, and the flavor and taste scheduled in the user's oral cavity is exhibited. When crushing the capsule member 23, the movement of the capsule member 23 is inhibited, so that the user can easily crush the capsule member 23 at a desired timing, thereby enjoying the changed flavor and taste Can.

Then, the manufacturing process of cigarette 11 which is an example of the smoking article of this embodiment is explained. The aerosol generating rod 14 is formed by winding the paper roll 13 around the tobacco cut 12 as usual. On the other hand, in the manufacturing line of the filter unit 15, the manufacturing apparatus of the filter unit 15 continuously forms the adhesive 24 at a position near the central axis C of the filter unit 15 before the filter body 17 is completely converged into a cylindrical shape. And supply linearly. At this time, the adhesive is heated to 100 to 200 ° C. to be in a melted state. Furthermore, the manufacturing apparatus of the filter unit 15 supplies the capsule member 23 in the vicinity of the central axis C of the filter main body 17 with the adhesive 24 supplied as described above. Further, the filter portion 15 is completely formed into a cylindrical shape, and then the adhesive portion 24 is solidified by leaving the filter portion 15 at room temperature. Thereby, the position of the capsule member 23 with respect to the filter body 17 is completely fixed.

Then, the movement prevention effect | action of the capsule member 23 in the cigarette 11 which is an example of the smoking article of this embodiment is demonstrated. The inventors conducted a test on seven subjects using the cigarette 11 of the present embodiment, "by intentionally pressing the capsule member 23 into the oral cavity by biting the capsule member with teeth". The In the test, the cigarette 11 of the present embodiment was used, and as a comparative example, a cigarette in which the conventional capsule member 23 and the filter body 17 were not adhered was used. As a result, in the conventional cigarette of the comparative example, one of seven subjects was able to push the capsule member 23 into the oral cavity. On the other hand, in the cigarette 11 of the present embodiment, none of the seven subjects was able to push the capsule member 23 into the oral cavity.

In the present test, since the test "consciously push the capsule member 23 into the oral cavity" is performed, one of seven subjects in the comparative example can push the capsule member 23 into the oral cavity. The On the other hand, in the normal use state, the possibility that the capsule member 23 is pushed out into the oral cavity in the comparative example is considered to be extremely close to zero. According to the present embodiment, even if it is intended to push the capsule member 23 consciously, it is impossible to move the capsule member 23 and push it out of the filter unit 15, so the capsule member 23 moves. It can be said that the cigarette 11 with extremely low possibility of being realized was realized.

According to the present embodiment, the smoking article includes the aerosol generating rod 14 and the filter unit 15 provided adjacent to the aerosol generating rod 14, and the filter unit 15 holds the filter body 17 and the fragrance inside. In addition, the capsule member 23 embedded in the filter body 17 and the adhesive 24 bonding the filter body 17 and the capsule member 23 are provided.

In general, the fibers constituting the filter unit 15 extend in the axial direction (central axis C direction) of the filter unit 15. For this reason, when an external force is applied to the capsule member 23, it is very rare that the capsule member 23 moves so as to escape along the direction in which the fibers extend. However, such occurrence of such an event was very rare, and such was hardly recognized as a problem by the manufacturer. According to the above configuration, by fixing the capsule member 23 to the filter main body 17 with the adhesive 24, it is possible to prevent the capsule member 23 from being displaced in position in the filter unit 15. As a result, it is possible to prevent the occurrence of a situation where the capsule member 23 moves so as to escape and becomes indivisible, and the convenience for the user can be improved.

The adhesive 24 is a thermoplastic resin. According to this configuration, since the resin is completely solid when the product is shipped, it is possible to prevent the capsule member 23 from moving in the filter unit 15, and the capsule member 23 can be easily broken. realizable. In addition, since moisture does not come out from the adhesive 24 at the time of solidification, the capsule member 23 can be prevented from being weakened by water.

The film of the capsule member 23 is made of a hydrophilic material, which is weakened by water absorption. In particular, the film of the capsule member 23 is formed of a material selected from starch, dextrin, polysaccharides, agar, gellan gum, gelatin, natural gelling agent, glycerin, sorbitol, calcium chloride, and mixtures thereof. According to these configurations, the capsule member 23 may be weakened by using a moisture-free adhesive such as a thermoplastic adhesive rather than using a moisture-containing adhesive such as vinyl acetate glue. Thus, the capsule member 23 can be prevented from becoming hard to break.

The capsule member 23 is located near the central axis C of the filter unit 15, and the adhesive 24 linearly extends along the central axis C near the central axis C of the filter unit 15. According to this configuration, the adhesive 24 extends linearly along the central axis C even when the installation position of the capsule member 23 is displaced with respect to the central axis C direction due to the dispersion at the time of manufacture. A slight positional deviation of 23 can be tolerated, and the capsule member 23 can be reliably fixed to the filter portion 15.

The capsule member 23 is located near the central axis C of the filter unit 15, and a part of the adhesive 24 is located in a projected cross section in the central axis C direction of the capsule member 23. According to this configuration, the adhesive 24 can be disposed at a position overlapping with the capsule member 23. By this, the adhesive 24 is not applied to the position away from the capsule member 23, and it is possible to prevent the problem that the adhesion between the capsule member 23 and the filter portion 15 is not performed well.

The adhesive 24 contains a fragrance. According to this configuration, the adhesive 24 can contain a perfume, which eliminates the need for separately providing a cotton yarn or the like containing the perfume in the filter portion 15. As a result, various flavors can be added to the mainstream smoke, and the degree of freedom can be improved at the time of product design, and the manufacturing process can be simplified as compared with the case of separately providing cotton yarn etc. The manufacturing cost can be reduced.

The adhesive 24 contains a pigment. According to this configuration, the adhesive 24 can be colored, and the portion where the adhesive 24 has solidified can be decorated. That is, the color of the portion of the filter portion 15 to which the adhesive 24 is applied is generally substantially the same as the color of the portion of the filter portion 15 to which the adhesive 24 is not applied. The portion of the filter portion 15 to which the adhesive 24 is applied is merely harder than the other portions. According to the above-mentioned configuration, it is possible to positively contribute to the improvement of the aesthetic appearance in the portion where the adhesive 24 is applied, and it is possible to improve the degree of freedom in the design of the smoking article.

The capsule member 23 is positioned closer to the suction end 26 than a position moved 15 mm in the central axis C direction from the suction end 26 of the filter portion 15 toward the aerosol generating rod 14 or a position moved 10 mm. According to this configuration, the capsule member 23 can be disposed close to the suction end 26, and the perfume can be placed on the mainstream smoke at a position close to the user's mouth. By this, the capsule member 23 can be disposed at a position where the perfume can be delivered most efficiently into the user's oral cavity. Furthermore, in the present embodiment, since the capsule member 23 and the filter unit 15 are bonded by the adhesive 24, even in the case of such an arrangement, the capsule member 23 may be detached from the filter unit 15 Can be prevented.

(First modification)
Then, the 1st modification of the smoking article (cigarette) of an embodiment is explained. The first modification is different from the above embodiment in that the material of the film 22 of the capsule member 23 is different and the type of the adhesive 24 is different, but other parts are common to the above embodiment. There is. In the following, portions different from the above embodiment are mainly described, and the description of the portions common to the above embodiment is omitted.

The capsule member 23 (coating 22) is formed of a resin material (synthetic resin material). More specifically, the capsule member 23 is formed of, for example, a polyethylene resin material, but may be formed of another type of resin material (synthetic resin material) such as polypropylene, polyurethane, polyvinyl chloride and the like. For example, the melting point of the capsule member 23 formed of polypropylene is 104 to 120 ° C., which is lower than 150 to 180 ° C. which is the melting point of the thermoplastic resin (hot melt adhesive). For this reason, when a thermoplastic resin (hot melt adhesive) is used as the adhesive 24, there is a possibility that the capsule member 23 may be punctured when it is melted.

Unlike the embodiment, the adhesive 24 of the present modification is formed of a water-dispersed adhesive. In the case of the water-dispersed adhesive, the adhesion ability is developed by evaporation of water at normal temperature (room temperature). In the present embodiment, among the water-dispersed adhesives, for example, a vinyl acetate resin emulsion adhesive can be suitably used as the adhesive 24.

According to this modification, the adhesive 24 is a water-dispersed adhesive. According to this configuration, inexpensive and safe adhesive 24 can be used. For this reason, since the adhesive 24 is liquid from the beginning, it is not necessary to apply heat to melt the adhesive 24. Therefore, when the capsule member 23 is formed of a resin material or the like, the adhesive 24 made of a thermoplastic resin (hot melt adhesive) is heated and melted to be applied to the filter portion 15 and the capsule member 23. The capsule member 23 can be prevented from being bored by heat.

The film 22 of the capsule member 23 is formed of a resin material. According to this configuration, when a water-dispersed adhesive is used as the adhesive 24, the capsule member 23 does not absorb the moisture exfoliated (vaporized) from the water-dispersed adhesive, and the capsule member 23 uses the moisture. It can prevent that the situation which becomes difficult to divide 23 arises.

The heating element of the electrical heating unit 43 heats the aerosol generating rod 14 to release the flavor from the filling 61 of the aerosol generating rod 14 into the surrounding air. The heating temperature of the aerosol generating rod 14 by the electrical heating unit 43 is, for example, 400 ° C. or less, which is considerably lower than the combustion temperature 700 to 800 ° C. of a cigarette of the conventional type to be ignited. By heating at such a low temperature, the amount of mainstream smoke generated from the aerosol generating rod 14 is reduced compared to the cigarette 11 and the like of the embodiment. For this reason, compared with the filter part 15 in the cigarette 11 of the embodiment, the filtering function in the filter part 15 of the present modification is preferable to have a lower filtering function in terms of the mainstream smoke amount shared in the mouth of the smoker . In this modification, in order to reduce mainstream smoke filtration of the filter unit 15, the length of the filter unit 15 in the direction of the central axis C is shorter than that of the above embodiment. It is also possible to shorten the length of the filter portion in which the filter body is disposed, and to dispose the cylindrical portion and other segments having a low filtration rate of mainstream smoke in the remaining portion.

The rod member 46 has a cigarette shape. The rod member 46 includes a cylindrical portion 51, the aerosol generating rod 14 provided at one end 51A of the cylindrical portion 51, and the other end of the cylindrical portion 51 opposite to the one end 51A. A second filter portion 31 provided coaxially with the aerosol generation rod 14 at a position between the aerosol generation rod 14 and the filter portion 15, and a cylindrical portion 51. , An aerosol generating rod 14, and a tipping paper member 16 connecting the filter unit 15.

The cylindrical portion 51 is formed in a cylindrical shape so as to have a predetermined rigidity by, for example, a thick paper of 100 to 300 μm in thickness. The tip paper member 16 is supported by the rigid cylindrical portion 51, and even when the rod member 46 is pressed in the central axis C direction, the tip paper member 16 is not crushed in the central axis C direction. The tipped paper member 16 and the tubular portion 51 have a plurality of vent holes 53 in a part of the outer periphery thereof. The plurality of air vents 53 penetrate the tipping paper member 16 and the cylindrical portion 51. The number of vent holes 53 is, for example, 10 to 40. The plurality of ventilation holes 53 are, for example, arranged in a line and annularly disposed on the outer peripheral portion of the cylindrical portion. The plurality of vent holes 53 are formed at regular intervals.

The aerosol generating rod 14 may be tobacco cut 12 (cuts, tobacco), tobacco sheet cut, folded or circumferentially wound tobacco sheet, pleated tobacco sheet, or non-cigarette A filler 61 containing a filler and the like, and a paper roll 54 wound around the filler 61 are included. The paper roll 54 may be paper, or may be made of paper laminated with heat conductive metal foil such as aluminum foil or stainless steel foil.

The configuration of the filter unit 15 has substantially the same configuration as that of the other embodiments except that the length of the filter body 17 in the direction of the central axis C is short. The filter unit 15 is embedded in the cylindrical filter body 17, the filter wrapping paper 21 wound around the filter body 17, and the filter unit 15 (in the filter body 17). And a capsule member 23 for holding a content liquid containing a perfume, and an adhesive 24 for bonding the filter body 17 and the capsule member 23 together. The capsule member 23 is positioned closer to the suction end 26 than a position moved 10 mm in the central axis C direction from the suction end 26 of the filter unit 15 toward the aerosol generating rod 14. More preferably, the capsule member 23 is positioned closer to the suction end 26 than a position moved 6 mm in the central axis C direction from the suction end 26 of the filter unit 15 toward the aerosol generating rod 14.

The second filter portion 31 is different from the filter portion 15 in that the second filter portion 31 does not have the capsule member 23, but the other portions are the same as the filter portion 15. In the present modification, the second filter unit 31 is configured by one, but may naturally be two or more. The filter unit 15 and the second filter unit 31 are connected by a second filter wrapping paper 62.

Also in the present modification, the same function as that of the above embodiment can be exhibited. That is, the user can enjoy the taste of the smoking article in the oral cavity by performing suction via the filter portion 15 and the cylindrical portion 51 while the rod member 46 is attached to the main body 45.

According to this variation, the smoking article 41 has an electrical heating portion 43 for heating the aerosol generating rod 14. According to this configuration, also in the smoking article 41 belonging to the field of so-called electronic cigarettes, the easiness of the capsule member 23 can be improved, and the convenience of the user can be improved. In particular, in the case of the configuration using the electrical heating unit 43, the length of the filter body 17 in the filter unit 15 tends to be short because the amount of mainstream smoke is small. According to this modification, the movement of the capsule member 23 can be prevented even in the filter body 17 having a short length. As described above, it is extremely useful in product design that the movement of the capsule member can be effectively prevented in the smoking article 41 having the short filter body 17 which has a high possibility of the capsule member 23 falling off from the filter body 17.

A smoking article is not limited to what was described in the above-mentioned embodiment and each modification, in an operation phase, it can change and embody a component in the range which does not deviate from the gist. Therefore, it can naturally be applied to smoking articles that enjoy the flavor of tobacco without heating.
