[Embodiment]
An embodiment of a cigarette, which is an example of a smoking article, will be described. Some smoking items include smoking tools (electronic cigarettes) that can inhale the flavor of cigarettes by heating the cigarettes with cigarettes, cigarettes, hand-rolled cigarettes, cigarettes, heaters, etc., or by steaming the cigarettes with steam. Includes smoking tools that can suck the flavor of tobacco by heating tobacco with a carbon heat source, and smoking tools that can suck the flavor of tobacco without heating.

As shown in FIGS. 1 and 2, the cigarette 11 is adjacent to an aerosol-generating rod 14 containing a tobacco chopping 12 (chopped leaves, tobacco) and a wrapping paper 13 wrapped around the tobacco chopping 12 and an aerosol-generating rod 14. It includes a filter unit 15 provided above the aerosol generation rod 14 and a chip paper member 16 wound on the aerosol generation rod 14 and the filter unit 15 so as to connect them across the aerosol generation rod 14 and the filter unit 15. In the cigarette 11, a central axis C that passes through the center of the aerosol generation rod 14 and the center of the filter unit 15 can be defined.

The filter portion 15 is located inside the filter portion 15 (inside the filter main body 17), the filter main body 17 having a columnar shape, the filter wrapping paper 21 wound around the filter main body 17, and the inside of the film 22. Contains a capsule member 23 that holds the content liquid containing a fragrance, and an adhesive 24 that adheres the filter body 17 and the capsule member 23.

The chip paper member 16 that wraps the filter portion 15 may or may not have a plurality of ventilation holes in a part of the outer periphery thereof. When the ventilation holes are provided, the number of ventilation holes may be, for example, 10 to 40. In that case, the plurality of ventilation holes are arranged in a row on the outer peripheral portion of the chip paper member 16 that wraps the filter portion 15, for example, so as to form an annular shape. The plurality of ventilation holes are formed at substantially constant intervals. By providing a plurality of ventilation holes, air is taken into the filter portion 15 from the ventilation holes when smoking. By diluting the mainstream smoke with the outside air from the vents, it is possible to design products with the desired tar value.

As shown in FIG. 2, the cigarette 11 straddles the aerosol generation rod 14, the filter unit 15, the aerosol generation rod 14, and the filter unit 15 including the tobacco nick 12 and the wrapping paper 13 wrapped around the tobacco nick 12. It has an aerosol generation rod 14 and a chip paper member 16 wound on a filter portion 15 so as to connect them.

The capsule member 23 is embedded in the filter main body 17. One capsule member 23 may be present in the filter portion 15, or a plurality of (for example, 2 to 10) capsule members 23 may be present. The capsule member 23 is provided on the central axis C of the filter portion 15 or in the vicinity of the central axis C. The capsule member 23 is located at a position moved 15 mm in the central axis C direction from the mouthpiece end 26 of the filter portion 15 toward the aerosol generation rod 14, or located closer to the mouthpiece end 26 than the position moved by 15 mm. More preferably, the capsule member 23 is located closer to the mouthpiece end 26 than the position moved 10 mm in the central axis C direction from the mouthpiece end 26 of the filter portion 15 toward the aerosol generation rod 14. More preferably, the capsule member 23 is located closer to the mouthpiece end 26 than the position moved 7 mm in the central axis C direction from the mouthpiece end 26 of the filter portion 15 toward the aerosol generation rod 14. By adopting 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 chewed by a tooth when smoking, and the flavor source becomes a mouthpiece. The proximity to the edge allows smokers to experience a stronger fragrance.

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, polysaccharide, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride and the like can be used in the film 22, and further, a fragrance and a coloring agent can be contained. The capsule member 23 is preferably colored so that the smoker can recognize it when the capsule member 23 is crushed even if it is surrounded by the opaque filter wrapping paper 21 and the chip paper member 16. For example, it is preferable to include blue No. 1 and the like. It can be said that the film 22 of the capsule member 23 is made of a material that is fragile due to water absorption when it contains a hydrophilic material.

As the fragrance of the content liquid, any fragrance used for smoking articles such as menthol and vegetable essential oil can be used. The main flavors are menthol, leaf tobacco extract, natural vegetable flavors (eg cinnamon, sage, herbs, chamomile, kudzu, sweet tea, cloves, lavender, cardamon, chow, nutmeg, bergamot, geranium, honey essence, rose. Oil, Lemon, Orange, Kay Skin, Caraway, Jasmine, Ginger, Coriander, Vanilla Extract, Spare Mint, Peppermint, Cassia, Coffee, Cellory, Cascarilla, Sandalwood, Cocoa, Iran Iran, Fennel, Anis, Licoris, St. John's Bread , Sumomo extract, peach extract, etc.), sugars (eg, glucose, fructose, isomerized sugar, caramel, etc.), cocoa (powder, extract, etc.), esters (eg, isoamyl acetate, linalyl acetate, isoamyl propionate, butyric acid) Linalyl, etc.), ketones (eg, menthon, ionone, damasenone, ethylmaltor, etc.), alcohols (eg, geraniol, linalol, anatorol, eugenol, etc.), aldehydes (eg, vanillin, benzaldehyde, anisaldehyde, etc.), lactones. Classes (eg, γ-undecalactone, γ-nonalactone, etc.), animal fragrances (eg, musk, ambassalis, civet, castorium, etc.), hydrocarbons (eg, limonene, pinen, etc.). These fragrances may be used alone or in combination.

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

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

The capsule member 23 can have, for example, the shape of a sphere or a cylinder, where the sphere includes either a sphere having a substantially circular cross section or an ellipsoid having an elliptical cross section. The capsule member 23 preferably has a spherical shape having a substantially circular cross section. In the case of a sphere having a substantially circular cross section, the capsule member 23 can have a diameter of, for example, 1.0 to 8.0 mm, and in the case of an ellipsoid, the capsule member 23 has, for example, a maximum diameter of 2.0 to 8.0 mm and a minimum diameter of 1. It can be 0 to 7.0 mm, and in the case of a cylindrical body, the diameter of the 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 commonly distributed cigarette, a capsule having a diameter smaller than the diameter of the generally distributed cigarette and filter portion of 7.5 to 8.0 mm should be used. Is. When applying a spherical capsule member to a cigarette that is generally distributed, it is preferable to use a capsule member having a diameter of 3.0 mm to 4.5 mm. If the capsule diameter is too small, the amount of fragrance applied to the cigarette will be less and the satisfaction that the fragrance can give will be lessened, and smokers will find the presence of the capsule when crushing 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 becomes large, so that the ventilation resistance of the filter part when the capsule is not crushed becomes too large, making it difficult for smokers to smoke. It makes me feel.

The filter body 17 may be composed of a filter medium of a cellulose acetate fiber bundle (acetate tow), like a normal cigarette with a filter. The filter main body 17 may be composed of only an acetate tow filter medium, or may be composed of an acetate tow filter medium and a filter wrapping paper 21 wrapped around the acetate tow filter medium. When the filter unit 15 includes a plurality of filter bodies 17, the filter body 17 on the tobacco chopping 12 side and the filter body 17 on the mouthpiece side may have the same material and structure, or may have different materials and structures. You may have.

Acetate tow has, for example, 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 (lines), and a ventilation resistance of 100 to 600 (mmH2O /). 120 mm). The single yarn fineness, total fineness, and number of fibers should be designed to achieve the target value of airflow 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 can be added in an amount of 5 to 12% by weight based on the weight of the acetate tow, and activated carbon is dispersed between the fibers of the acetate tow. When added, the plasticizer can be added in an amount of 2-12% by weight based on the weight of the acetate tow.

The filter unit 15 has a circumference of, for example, about 14 to 26 mm, and the length can be, for example, 17 to 40 mm, similar to a normal filter.

The aerosol-generating rod 14, like a normal cigarette 11, consists of a tobacco chopping 12 and a tobacco roll 13 that wraps around it, and can have, for example, a circumference of about 14-26 mm and a length of 20-70 mm. ..

The adhesive 24 is provided over the entire length of the filter portion 15 in the longitudinal direction (center axis C direction). The adhesive 24 is provided linearly on or near the central axis C of the filter portion 15 along 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 of the capsule member 23 in the central axis C direction. The adhesive 24 adheres the capsule member 23, which is also located on the central axis C, to the filter body 17.

A part of the adhesive 24 is 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 portion 15, it is liquefied by raising the temperature to a high temperature of 100 to 200 ° C. 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 ratio of 10 to 50 mg per 120 mm in length 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, the area covering the surface of the capsule member 23 is preferably 1/2 or less, for example. If the adhesive 24 covers more than half of the surface area of the capsule member 23, the adhesive 24 functions as a kind of coating, so that the capsule member 23 becomes too hard and difficult to crush with a finger. Become.

The fragrance may be uniformly added to the adhesive 24. It is considered that the preferable amount of the fragrance when these fragrance components are uniformly contained in the adhesive 24 is an amount that does not cause deterioration of the function of the adhesive 24. The amount of the fragrance uniformly contained in the adhesive 24 can be appropriately adjusted by increasing or decreasing the amount for scenting the mainstream smoke of the cigarette 11 (smoking article).

These perfume components may be directly dispersed in the adhesive 24, or these perfume components may be encapsulated in an inclusion body such as dextrin, α-cyclodextrin, β-cyclodextrin, and then the adhesive 24. It may be dispersed within. By adopting such a method, it is possible to reduce the influence of the adhesive 24 on the adhesive force by dispersing the adhesive in the adhesive 24.

Examples of the fragrance added to the adhesive 24 include the following. For example, acetoanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, trans-annetol, staranis oil, apple juice, peruval balsam oil, mitsuro absolute, benzaldehyde, benzoin resinoid, benzyl alcohol. , Benzyl benzoate, benzyl phenylacetate, benzyl propionate, 2,3-butandione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamon oil, carobu absolute , β-carotene, carrot juice, L-carboxylic, β- Cariophyllene, Cassia bark oil, Cedarwood oil, Cellory seed oil, Camomil oil, Shinamaldehyde, Cycyl acid, Synamyl alcohol, Synamyl silicic acid, Citronella oil, DL- Citronellol , Clarisage extract, Cocoa, Coffee, Cognac Oil, coriander oil, cuminaldehyde, davana oil, δ-decalactone, γ-decalactone, decanoic acid, dill herb oil, 3,4-dimethyl-1,2-cyclopentandione, 4,5-dimethyl-3-hydroxy- 2,6-Dihydrofuran-2-one, 3,7-dimethyl-6-octenoic acid, 2,3-dimethylpyrazine, 2,5-dimethylpyrazine, 2,6-dimethylpyrazine, ethyl 2-methylbutyrate, acetic acid Ethyl, ethyl butyrate, ethyl hexanoate, ethyl isovalerate, ethyl lactate, ethyl laurylate, ethyl levulinate, ethyl maltol, ethyl octanate, ethyl oleate, ethyl palmitate, ethyl phenylacetate, ethyl propionate, stearic acid Ethyl, 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, Eucalyptor, Phenuglique Absolute , Gene Absolute , Lindou Root Infusion, Geraniol, Geranyl Acetate, Grape Juice, Guayacol, Guava Extract, γ-Heptalactone, γ-Hexalactone, hexane Acid, cis-3-hexane-1-ol, hexyl acetate, hexyl alcohol, phenylacetate hexyl, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4- (3-hydroxy-1-butenyl)- 3,5,5-trimethyl-2- Cyclohexane-1-one, 4- (para-hydroxyphenyl) -2-butanone, sodium 4-hydroxyundecanoate, immortel absolute , β-ionone, isoamyl acetate, isoamyl butyrate, isoamyl phenylacetate, isobutyl acetate, isobutyl phenylacetate , Jasmine Absolute, Coconut Tinkture, Labdanum Oil, Lemon Terpenless Oil, Kanzo Extract, Linalol, Linalyl Acetate, Lopage Root Oil, Martol, Maple Syrup, Mentor (L-Mentor), Menton, L-Acetic Acid Menthyl, paramethoxybenzaldehyde, methyl-2-pyrrrolketone, methyl anthranilate, methyl phenylacetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methylvaleric acid, mimosa absolute , toumitsu, myristic acid , Nerol, nerolidol, γ-nonalactone, nutmeg oil, δ-octalactone, octanal, octanoic acid, orange flower oil, orange oil, oris oil, palmitic acid, peppermint oil, petitgrain paraguay oil, phenethyl alcohol, phenylacetic acid Phenethyl, phenylacetic acid, piperonal , plum extract, propenylguaetol, propyl acetate, 3-providenephthalide, prune juice, pyruvate, raisin extract, rose oil, lamb liquor, sage oil, sandalwood oil, spearmint oil , Stilax absolute, marigold oil, tea distillate, α-terpineol, terpinyl acetate, 5,6,7,8 -tetrahydroquinoxaline, 1,5,5,9 -tetramethyl-13-oxacyclo (8.3.0.0 (4.9)) Tridecane, 2,3,5,6-tetramethylpyrazine, thyme oil, tomato extract, 2-tridecanone, trimethyl citrate, 4- (2,6) 6-trimethyl-1,3-cyclohexenyl) 2-butene-4-one, 2,6,6-trimethyl-2-cyclohexene-1,4-dione, 4- (2,6,6-trimethyl-1, 4, 3-Cyclohexadienyl) 2-butene-4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin, veratoraldehyde , violet leaf absolute.

These fragrances may be used alone or in combination of two or more in order to realize the desired scent.

The fragrance dispersed in the adhesive 24 is fixed in the adhesive 24 before smoking, and volatilization to the outside of the adhesive 24 hardly occurs. On the other hand, when smoking, mainstream smoke passes in the vicinity of the adhesive 24. The heat of the mainstream smoke and / or the moisture (steam) contained in the mainstream smoke volatilizes the fragrance fixed in the adhesive 24 into the mainstream smoke. As a result, a gap can be provided between the scent of the cigarette 11 (smoking article) before smoking and the scent of mainstream smoke during smoking, which can surprise the smoker. Further, it takes a predetermined time from the start of smoking until the fragrance fixed in the adhesive 24 is volatilized in the mainstream smoke, that is, the fragrance fixed in the adhesive 24 is in the mainstream smoke from the start of smoking. It is also possible to have a time lag before it is volatilized.

A dye such as a dye or a pigment can be uniformly mixed in the adhesive 24. As such a pigment, for example, an edible pigment can be used. Examples of food coloring include natural pigments such as ponceau yellow pigment, anato pigment, ponceau pigment, red cabbage pigment, ponceau 4R pigment, and ponceau blue pigment, and food coloring No. 2, edible red No. 3, and food coloring No. 102. Examples thereof include synthetic pigments such as edible red No. 104, edible red No. 105, edible yellow No. 4, edible yellow No. 5, edible blue No. 1, and edible blue No. 2.

The operation of the cigarette 11 of the present embodiment will be described. In the cigarette 11 of the present embodiment, the user can enjoy the taste of tobacco by igniting the tip of the aerosol generation rod 14, holding the mouthpiece end 26 of the filter unit 15 by mouth, and sucking the cigarette. At that time, the fragrance contained in the content liquid of the capsule member 23 or the fragrance volatilized from the adhesive 24 is mixed with the mainstream smoke, and the expected flavor taste is exhibited in the user's oral cavity. When the capsule member 23 is crushed, the movement of the capsule member 23 is hindered, so that the user can easily crush the capsule member 23 at a desired timing and enjoy the changed flavor and taste. Can be done.

Subsequently, the manufacturing process of the cigarette 11 which is an example of the smoking article of this embodiment will be described. The aerosol-forming rod 14 is formed by winding the rolling paper 13 around the tobacco chopping 12 as usual. On the other hand, in the production line of the filter unit 15, the manufacturing apparatus of the filter unit 15 continuously applies 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 (linearly). At this time, the adhesive is in a melted state by being heated to 100 to 200 ° C. Further, the manufacturing apparatus of the filter unit 15 supplies the capsule member 23 to the vicinity of the central axis C of the filter main body 17 in the state where the adhesive 24 is supplied in this way. Further, the filter portion 15 is completely formed into a cylindrical shape, and then the filter portion 15 is left at room temperature to solidify the adhesive 24. As a result, the position of the capsule member 23 with respect to the filter body 17 is completely fixed.

Subsequently, the movement prevention action of the capsule member 23 in the cigarette 11 which is an example of the smoking article of the present embodiment will be described. Using the cigarette 11 of the present embodiment, the inventors conducted a test in which seven subjects were "consciously pushed out the capsule member 23 into the oral cavity by chewing the capsule member with their teeth". rice field. 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 main body 17 were not adhered was used. As a result, in the conventional cigarette of the comparative example, one out of seven subjects was able to extrude 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 this test, since the test of "consciously pushing the capsule member 23 into the oral cavity" is performed, one out of seven subjects in the comparative example can push the capsule member 23 into the oral cavity. rice field. On the other hand, under normal use conditions, the possibility that the capsule member 23 is extruded into the oral cavity is considered to be extremely close to zero even in the comparative example. According to the present embodiment, even when the capsule member 23 is intentionally pushed out, it is impossible to move the capsule member 23 and push it out from the filter unit 15, so that the capsule member 23 moves. It can be said that the cigarette 11 that is extremely unlikely to be used has been realized.

According to the present embodiment, the smoking article includes an aerosol generation rod 14 and a filter unit 15 provided adjacent to the aerosol generation rod 14, and the filter unit 15 holds the filter main body 17 and the fragrance inside. At the same time, it has a capsule member 23 embedded in the filter main body 17 and an adhesive 24 for adhering the filter main body 17 and the capsule member 23.

Normally, the fibers constituting the filter unit 15 extend in the axial direction (central axis C direction) of the filter unit 15. Therefore, when an external force is applied to the capsule member 23, the capsule member 23 rarely moves so as to escape along the extending direction of the fiber. However, since it was extremely rare for such an event to occur, such an event was rarely 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 the filter portion 15. As a result, it is possible to prevent the occurrence of a situation in which the capsule member 23 moves so as to escape and becomes difficult to break, and the convenience of the user can be improved.

The adhesive 24 is a thermoplastic resin. According to this configuration, since the resin is completely solid in the state where the product is shipped, the capsule member 23 is prevented from moving in the filter portion 15, and the smoking article in which the capsule member 23 is easily broken is produced. realizable. Further, since water does not come out from the adhesive 24 when solidified, it is possible to prevent the capsule member 23 from becoming fragile due to water.

The film of the capsule member 23 is a hydrophilic material and is composed of a material that is fragile due to 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 agents, glycerin, sorbitol, calcium chloride, and mixtures thereof. According to these configurations, the capsule member 23 may be fragile by using a moisture-free adhesive such as a thermoplastic adhesive rather than using a moisture-containing adhesive such as vinyl acetate glue. It is possible to prevent the capsule member 23 from becoming difficult to break.

The capsule member 23 is located near the central axis C of the filter portion 15, and the adhesive 24 extends linearly along the central axis C near the central axis C of the filter portion 15. According to this configuration, even if the installation position of the capsule member 23 is displaced with respect to the central axis C due to variations during manufacturing, the adhesive 24 extends linearly along the central axis C, so that the capsule member A slight misalignment of the 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 portion 15, and a part of the adhesive 24 is located in the projected cross section of the capsule member 23 in the central axis C direction. According to this configuration, the adhesive 24 can be arranged at a position overlapping with the capsule member 23. This prevents the adhesive 24 from being applied to a position separated from the capsule member 23, and prevents problems such as poor adhesion between the capsule member 23 and the filter portion 15.

The adhesive 24 contains a fragrance. According to this configuration, the adhesive 24 can contain a fragrance, so that it is not necessary to separately provide a cotton thread or the like containing the fragrance in the filter portion 15. As a result, various flavors can be added to the mainstream smoke, 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 where a cotton thread or the like containing a fragrance is separately provided. Manufacturing cost can be reduced.

The adhesive 24 contains a dye. According to this configuration, the adhesive 24 can be colored, and the portion where the adhesive 24 is solidified can be decorated. That is, the color of the portion of the filter portion 15 to which the adhesive 24 is applied is usually almost 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 simply harder than the other portions. According to the above configuration, it is possible to positively contribute to the improvement of the aesthetic appearance at 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 located on the mouthpiece end 26 side of the position where the filter portion 15 is moved 15 mm or 10 mm in the central axis C direction from the mouthpiece end 26 toward the aerosol generation rod 14. According to this configuration, the capsule member 23 can be arranged close to the mouthpiece end 26, and the fragrance can be placed on the mainstream smoke at a position close to the user's mouth. As a result, the capsule member 23 can be arranged at a position where the fragrance can be delivered most efficiently into the oral cavity of the user. Further, in the present embodiment, since the capsule member 23 and the filter portion 15 are adhered to each other by the adhesive 24, even if such an arrangement is adopted, the capsule member 23 may fall off from the filter portion 15. Can be prevented.

(First modification)
Subsequently, a first modification of the smoking article (cigarette) of the embodiment will be described. 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, the parts different from the above-described embodiment will be mainly described, and the description of the parts common to the above-mentioned embodiment will be 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, and polyvinyl chloride. For example, the melting point of the capsule member 23 made of polypropylene is 104 to 120 ° C., which is lower than the melting point of the thermoplastic resin (hot melt adhesive) of 150 to 180 ° C. Therefore, if a thermoplastic resin (hot melt adhesive) is used as the adhesive 24, there is a possibility that a hole may be formed in the capsule member 23 when the adhesive 24 is melted.

Unlike the embodiment, the adhesive 24 of this modification is composed of a water-dispersive adhesive. The water-dispersible adhesive develops its adhesive ability by evaporation of water at room temperature (room temperature). In the present embodiment, among the water-dispersible adhesives, for example, a vinyl acetate resin emulsion adhesive can be suitably used as the adhesive 24.

The arrangement of the adhesive 24, the fragrance may be mixed with the adhesive 24, and the dye may be mixed with the adhesive 24 are the same as those in the above embodiment. According to this modification, since the capsule member 23 is formed of a resin material, the strength of the capsule member 23 is improved, and a problem that the capsule member 23 is unintentionally crushed during transportation or the like is prevented.

According to this modification, the adhesive 24 is a water-dispersible adhesive. According to this configuration, an inexpensive and safe adhesive 24 can be used. Therefore, 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, and is applied to the filter portion 15 and the capsule member 23. It is possible to prevent the capsule member 23 from being punctured by heat.

The film 22 of the capsule member 23 is formed of a resin material. According to this configuration, when the water-dispersion adhesive is used as the adhesive 24, the capsule member 23 does not absorb the water dissipated (volatilized) from the water-dispersion adhesive, and the water disperses the capsule member. It is possible to prevent a situation in which 23 becomes difficult to break.

The heating temperature of the aerosol generation rod 14 by the electric heating unit 43 is, for example, 400 ° C. or lower, which is considerably lower than the combustion temperature of 700 to 800 ° C. of the type of cigarette that is ignited as in the conventional type. By heating at such a low temperature, the amount of mainstream smoke generated from the aerosol generation rod 14 is smaller than that of the cigarette 11 or the like of the embodiment. Therefore, as for the filtration function in the filter unit 15 of the present modification, the lower filtration function is more suitable than the filter unit 15 in the cigarette 11 of the embodiment, and the mainstream smoke amount shared in the smoker's mouth is preferable. .. In this modification, in order to reduce the mainstream smoke filtration of the filter unit 15, the length of the filter unit 15 with respect to the central axis C direction is shorter than that of the above embodiment. Of the total length of the filter portion, the length in which the filter main body is arranged can be shortened, and the cylinder portion and other segments having a low filtration rate of mainstream smoke can be arranged in the remaining portion.

The rod member 46 has a cigarette shape. The rod member 46 includes a tubular portion 51, an aerosol-generating rod 14 provided at one end 51A of the tubular portion 51, and the other on the opposite side of the one end 51A of the tubular portion 51.

The chip paper member 16 is supported by a rigid tubular portion 51, and even when the rod member 46 is pressed in the central axis C direction, the chip paper member 16 does not collapse in the central axis C direction. The chip paper member 16 and the tubular portion 51 have a plurality of ventilation holes 53 in a part of the outer periphery thereof. The plurality of ventilation holes 53 penetrate the chip paper member 16 and the tubular portion 51. The number of ventilation holes 53 is formed, for example, 10 to 40. The plurality of ventilation holes 53 are arranged in a row, for example, in an annular shape on the outer peripheral portion of the cylinder portion. The plurality of ventilation holes 53 are formed at regular intervals.

The aerosol generation rod 14 includes tobacco chopped 12 (chopped leaves, tobacco), tobacco sheet chopped, tobacco sheet folded or rolled in a circle, tobacco sheets gathered together with folds, or other than tobacco. It has a filler 61 containing a filler and the like, and a wrapping paper 54 wrapped around the filler 61. The wrapping paper 54 may be paper, or is formed of paper to which a metal foil having good thermal conductivity such as aluminum foil or stainless steel foil is bonded.

The configuration of the filter unit 15 has substantially the same configuration as that of other embodiments, except that the length of the filter main body 17 in the central axis C direction is short. The filter portion 15 is located inside the filter portion 15 (inside the filter main body 17), the filter main body 17 having a columnar shape, the filter wrapping paper 21 wound around the filter main body 17, and the inside of the film 22. Contains a capsule member 23 that holds the content liquid containing a fragrance, and an adhesive 24 that adheres the filter body 17 and the capsule member 23.

More preferably, the capsule member 23 is located closer to the mouthpiece end 26 than the position moved 6 mm in the central axis C direction from the mouthpiece end 26 of the filter portion 15 toward the aerosol generation rod 14.

The second filter unit 31 is different from the filter unit 15 in that it does not have the capsule member 23, but the other parts are the same as the filter unit 15. In this modification, the second filter unit 31 is composed of one, but of course, two or more may be used. The filter unit 15 and the second filter unit 31 are connected by a second filter wrapping paper 62.

The same operation as that of the above-described embodiment is exhibited by this modification as well. That is, the user can enjoy the flavor of the smoking article in the oral cavity by performing suction through the filter portion 15 and the tubular portion 51 while the rod member 46 is attached to the main body 45.

According to this modification, the smoking article 41 has an electrical heating unit 43 for heating the aerosol generation rod 14. According to this configuration, the ease of splitting the capsule member 23 can be similarly improved in the smoking article 41 belonging to the field of so-called electronic cigarettes, and the convenience of the user can be improved. In particular, in the case of the configuration using the electric heating unit 43, the length of the filter main body 17 in the filter unit 15 tends to be short because the amount of mainstream smoke is small. According to this modification, it is possible to prevent the capsule member 23 from moving even in the filter body 17 having a short length. As described above, it is extremely useful in product design to be able to effectively prevent the capsule member from moving in the smoking article 41 having the short filter body 17, which is likely to cause the capsule member 23 to fall off from the filter body 17.

The smoking article is not limited to those described in the above-described embodiment and each modification, and at the implementation stage, the components can be modified and embodied within a range that does not deviate from the gist thereof.
