The adhesive bonds the filter body and the capsule member.

Description

Technical field

The invention relates to a smoking article containing a capsule element.

State of the art

A filtered smoking article, such as a conventional filtered cigarette, includes a filter portion, a tobacco portion, and a tip paper member. The filter portion is formed into a rod shape by wrapping a filter paper around a filter body containing cellulose acetate tow or a filter body formed from a non-woven material containing pulp. The tobacco portion is formed into a rod shape by wrapping the dried tobacco leaf with cigarette paper. The filter section and the tobacco section are joined end-to-end. The filter portion and the tobacco portion are wrapped around the whole periphery with a body paper member to adhere to each other to form one whole body.

Generally, as stated in Patent Document 1, for example, a flavoring capsule is inserted into the filter body of a cigarette. The smoker breaks the flavor capsule with his fingers to inhale the aroma created by the contents of the flavor capsule when smoking or mask the smell of a cigarette butt left from an extinguished cigarette. The flavor capsule is described in detail, for example, in Patent Document 2.

In addition to the cigarette, there are many smoking articles, such as cigars and cigarillos, which generate smoke by burning the tip of an aerosol-generating rod containing tobacco material. In addition, there are various smoking articles that release an aroma component by heating an aerosol generating rod containing an aerosol raw material such as tobacco material, an aroma component, and glycerin without burning. As non-combustion heating methods, there are various methods that can be used depending on the desired level, such as heating by electrical resistance, IH, chemical change, or phase change.

The aerosol generating rod comprises a tobacco rod formed by wrapping a dried tobacco leaf with cigarette paper and formed into a rod. In addition, the aerosol generating rod includes a rod formed by wrapping a dried tobacco sheet with a cigarette sheet, and a rod formed by impregnating a raw material other than a tobacco leaf with an aerosol source such as glycerin and an aroma component, and then wrapping the raw material with paper in the form of a rod. In any form, the aerosol-generating rod is substantially cylindrical, and in general, a filter section is located near and attached to one end of the aerosol-generating rod by wrapping with brown paper.

Examples of smoking articles in which the flavor component is generated by heating the aerosol generating rod without burning are described in Patent Documents 3 and 4.

Detailed description

Embodiments.

The following describes an embodiment of a cigarette, which is an example of a smoking article. The smoking article includes a cigarette, cigar, cigar, cigarillo, and a smoking device (electronic cigarette) that enables a user to inhale tobacco flavor by heating tobacco with a heater or the like, or steaming tobacco, a smoking device that enables a user to inhale tobacco flavor by heating with carbon a heat source or the like; and a non-heated type smoking device that enables the user to inhale the aroma of tobacco.

As shown in FIG. 1 and 2, a cigarette 11 includes an aerosol-generating rod 14 containing cut tobacco 12 (crushed tobacco leaves) and cigarette paper 13 wrapped around cut tobacco 12, a filter portion 15 adjacent to the aerosol-generating rod 14, and a tipping paper element 16 wrapped around the aerosol-generating rod 14 and the filter section 15 to attach the aerosol-generating rod 14 to the filter section 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 section 15 includes a filter body 17 of a cylindrical shape, a filter paper wrapper 21 wrapped around the filter body 17, a capsule element 23 which is embedded in the filter section 15 (inside the filter main body 17) and which retains the liquid content containing flavor inside the capsule. shell 22, and adhesive 24, which connects the main part 17 of the filter and the capsule element 23.

The tip paper member 16 that wraps the filter portion 15 may optionally be provided with a plurality of ventilation holes on a portion of the outer periphery. In the case where vent holes are provided, the number of vent holes may be, for example, from 10 to 40. In this case, a plurality of vent holes are arranged in a row in a circle, for example, in the outer peripheral part of the tip paper element 16 wrapped around the filter section 15 . Several ventilation holes are formed at substantially equal intervals. If there are multiple vents, air is drawn into the filter portion 15 through these vents when the user smokes. Dilution of the mainstream smoke with ambient air flowing through the vents provides product design with the required value for resins.

As shown in FIG. 2, the cigarette 11 includes an aerosol generating rod 14 containing cut tobacco 12 and cigarette paper 13 wrapped around cut tobacco 12, a filter portion 15, and a tipping paper member 16 disposed on the aerosol generating rod 14 and filter portion 15 so as to attach the aerosol generating rod 14 to the filter portion 15.

The capsule element 23 is embedded in the main body 17 of the filter. The number of capsule elements 23 in filter section 15 may be one or more (eg 2 to 10). The capsule element 23 is provided on or near the central axis C of the filter section 15 . The capsule element 23 is positioned at a distance of 15 mm or less from the mouth end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14. Preferably, the capsule element 23 is positioned at a distance of less than 10 mm from the mouth end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14. More preferably, the capsule element 23 is positioned at a distance of 7 mm or less from the mouth end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14. By adopting this arrangement, the user can easily destroy the capsule element 23, not only fingers, but also biting the capsule element with 23 teeth while smoking. In addition, since the flavor generating source is close to the mouth end, the smoker can enjoy a stronger flavor experience.

The capsule element 23 comprises a capsule shell 22 and a liquid content enclosed in the capsule shell 22 and containing flavor. The capsule shell 22 may contain, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerin, sorbitol, calcium chloride, and the like, and may further contain flavor and color. The capsule element 23 is preferably colored so that a smoker can recognize when the capsule element 23 breaks even though it is surrounded by an opaque filter paper wrapper 21 and a tip paper element 16 . The capsule shell 22 preferably contains a colorant, such as Food Blue #1, for example.

Any flavoring for a smoking article, such as menthol, vegetable essential oil, etc., can be used as the liquid content flavoring. Principal flavoring examples include menthol, tobacco leaf extract; natural plant flavors (eg, cinnamon, sage, herbs, chamomile, pueraria lobata, sweet hydrangea leaf, clover, lavender, cardamom, clove, nutmeg, bergamot, geranium, white sweet clover essential oil, rose oil, lemon, orange, bark cinnamon, cumin, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, croton wood, sandalwood, cocoa, ylang-ylang, fennel, anise, liquorice, carob, prune extract and extract pears), saccharides (eg, glucose, fructose, isomerized saccharides, and caramel), cocoa (eg, powder and extract), esters (eg, isoamyl acetate, linalyl acetate, isoamyl propionate, and linalyl butyrate), ketones (eg, menthone, ionone, damascenone, and ethyl maltol ), alcohols (such as geraniol, linalool, anethole, and eugenol), aldehydes (such as vanillin, benzaldehyde, and anisealdehyde), lactones (such as γ-undecalactone and γnonalactone), animal-derived flavors (such as mu skus, amber, civet and castoreum) and bicarbonates (for example, limonene and pinene). These flavors may be used singly or in combination.

As a solvent for the liquid content, a solvent suitable for this fragrance can be used. For example, medium chain fatty acid triglyceride (MCT) (in particular, caprylic/capric acid glyceride can be used), propylene glycol, water or ethanol. The liquid content may include other solvents and other additives such as pigment, emulsifier and thickener.

Although the manufacturing method of the capsule element 23 is not limited to any particular one, the falling drop method can be used to manufacture the capsule element 23 with the seamless capsule shell 22. This method uses a double nozzle. The liquid content is ejected from the inner side jet, and simultaneously the liquid material forming the capsule shell 22 is ejected from the outer side jet. As a result, the liquid material forming the capsule shell 22 can coat the liquid content without forming seams.

The capsule element 23 may be in the form of a sphere or a cylinder. The sphere includes a round object with a substantially circular section and an ellipsoidal object with an ellipsoidal section. Preferably, the encapsulating element 23 is a substantially circular object. If the capsule element 23 is a sphere of essentially circular cross section, it may have a diameter of, for example, from 1.0 to 8.0 mm. In the case of an ellipsoid, the capsule element 23 may have, for example, a maximum diameter of 2.0 to 8.0 mm and a minimum diameter of 1.0 to 7.0 mm. In the case of a cylinder, the capsule element 23 may have a diameter of 1.0 to 8.0 mm and a height of 1.0 to 8.0 mm. When the spherical capsule member is mainly applied to a common cigarette, a capsule with a diameter smaller than 7.5 to 8.0 mm, which is the diameter of a common cigarette and the filter portion, should be used. When the spherical capsular element is mainly applied to a dispersed cigarette, it is preferable to use a capsule element with a diameter of 3.0 to 4.5 mm. If the capsule diameter is too small, problems may arise; for example, the amount of flavor applied to a cigarette can be reduced, thereby reducing the sense of satisfaction that can be delivered by the flavor; and it can be difficult to detect the presence of the capsule when the capsule is broken open by the smoker. If the capsule diameter is too large, the ratio of the cross-sectional area of the capsule to the cross-sectional area of the main body of the filter increases, so that the ventilation resistance of the filter portion when the capsule is not broken becomes too large, causing the smoker to feel difficulty in inhaling.

The filter body 17 may be formed from a filter material in the form of a tow of cellulose acetate fiber (acetate fiber) as in the case of a conventional filter cigarette. The main body 17 of the filter may contain only an acetate fiber filter material, or may contain an acetate fiber filter material and a paper wrapper 21 of the filter wrapped around the filter material. If the filter section 15 comprises several filter main parts 17, the cut tobacco 12 side filter main body 17 and the mouth end side filter main body 17 may be of the same material and structure, or may be of different material and structure.

The acetate fiber can have a yarn thickness of 1.9 to 12.0 (g/9000 m), a total yarn thickness of 10000 to 44000 (g/9000 m), a fiber count of 830 to 23500 (fibers) and a pressure drop of 100 to 600(mm H2O/120mm). The thickness of the thread, the total thickness of the threads and the number of threads must be provided to achieve the target value of the ventilation resistance, depending on the given length around the periphery (from 14.0 to 26.0 (mm)) of the main filter body. A plasticizer such as triacetin may be added to the acetate fiber. The plasticizer may be added in an amount of 5 to 12 wt.% relative to the weight of the acetate fiber. If the dispersed activated carbon is added between the fibers of the acetate fiber, the plasticizer may be added in an amount of 2 to 12% by weight relative to the weight of the acetate fiber.

For example, filter portion 15 may have a circumferential length of about 14 to 26 mm and a length of, for example, 17 to 40 mm, as in a conventional filter.

The aerosol-generating rod 14, like a conventional cigarette 11, comprises cut tobacco 12 and cigarette paper 13 wrapped around the cut tobacco and may have, for example, a circumferential length of about 14 to 26 mm and a length of about 20 to 70 mm.

The adhesive 24 is provided along the entire length of the filter section 15 in the longitudinal direction (direction of the central axis C). The adhesive 24 is linearly provided on or near the central axis C of the filter section 15 along the central axis C of the filter section 15. Since the capsule element 23 is located on or near the central axis C, a part of the adhesive 24 is positioned within the sectional projection in the direction of the central axis C of the capsule element 23. The adhesive 24 connects the capsule element 23 and the main body 17 of the filter, which is also located on the central axis C.

The adhesive 24 is partially provided in an arc shape along the outer contour of the capsule member 23. The adhesive 24 is formed from a thermoplastic resin (hot melt adhesive). When adhesive 24 is applied to filter portion 15, it liquefies by heating to a high temperature of 100 to 200°C. However, at the time of delivery of the product, the adhesive 24 is completely solid. On the production line of the filter section 15, the adhesive 24 is applied continuously and linearly to the filter tow at a rate of 10 to 50 mg over a length of 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 entire surface area of the capsule element 23. The area covering the surface of the capsule element 23 is, for example, preferably 1/2 or less. If 1/2 or more of the encapsulation 23 is coated with the adhesive 24, the encapsulation 23 becomes too hard to break with the fingers as the adhesive 24 functions as a kind of coating.

Flavorants can be uniformly added to the adhesive 24. In the case of even addition of flavoring components to the adhesive 24, the preferred amount of flavoring components is considered to be the amount that does not cause dysfunction of the adhesive 24. The amount of flavoring agents evenly distributed in the adhesive 24 can be adjusted accordingly , for example, by increasing or decreasing the amount of added flavors to flavor the mainstream smoke of the cigarette 11 (smoking article).

These flavor components may be dispersed directly into the adhesive 24, or the flavor components may be incorporated into an inclusion compound such as dextrin, α-cyclodextrin, and β-cyclodextrin, and the inclusion compound may be dispersed into the adhesive 24. By adopting this method, it is also possible to reduce the effect on adhesive strength of adhesive 24 by dispersing aromatic components into adhesive 24.

Examples of flavors added to the adhesive 24 include the following. Examples include acetoanisole, acetophenone, acetylpyrazine, 2-acetylthiazole, alfalfa extract, amyl alcohol, amyl butyrate, transanethol, star anise star anise oil, apple juice, Peru balsam oil, pure beeswax, benzaldehyde, benzoic resinoid, benzyl alcohol, benzyl benzoate, benzyl phenylacetate, benzyl propionate, 2,3-butanedione, 2-butanol, butyl butyrate, butyric acid, caramel, cardamom oil, pure carob syrup, β-carotene, carrot juice, L-carvone, β-caryophyllene, cassia bark oil, cedar nut oil , celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acids, cinnamic alcohol, cinnamic cinnamate, citronella oil, DLcitronellol, clary sage extract, cocoa, coffee, cognac oil, coriander oil, cuminaldehyde, davana oil, δ-decalactone, γ- decalactone, decanoic acid, dill herb oil, 3,4dimethyl-1,2-cyclopentanedione, 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, ethyl acetate, ethyl butyrate, ethyl hexanoate, ethyl isovalerate, ethyl lactate, ethyl laurate, ethyl levulinate, ethyl maltol, ethyl octanoate, ethyl oleate, ethyl palmitate, ethyl phenyl acetate, ethyl propionate, ethyl stearate, ethyl valerate, ethyl vanillin , ethylvanillin glucoside, 2-ethyl-3,(5 or 6)dimethylpyrazine, 5-methyl-3-hydroxy-4-methyl2(5H)furanone, 2-ethyl-3-methylpyrazine, eucalyptol, pure fenugreek, pure gentian , gentian root infusion, geraniol, geranyl acetate, grape juice, guaiacol, guava extract, γ-heptalactone, γ-hexalactone, caproic acid, cis-3-hexan-1-ol, hexyl acetate, hexyl alcohol, hexyl phenyl acetate, honey, 4- pentenoic acid hydroxy-3-lactone, 4-hydroxy-4-(3-hydroxy-1-butenyl)-3,5,5trimethyl-2-cyclohexan-1-one, 4-(para-hydroxyphenyl)-2-butanone, sodium 4-hydroxyundecanoate, pure immortelle, β-ionone, isoamyl acetate, isoamyl butyrate, isoamylphenyl acetate, isobutyl acetate, isobutylphenyl acetate, pure jasmine Impurities, Coconut Tincture, Labdanum Oil, Lemon Antherpene Oil, Licorice Extract, Linalool, Linalyl Acetate, Lovage Root Oil, Maltol, Maple Syrup, Menthol (L-menthol), Menthone, L-Methyl Acetate, P-Methoxybenzaldehyde, Methyl-2-Pyrrolyl Ketone , methyl anthranilate, methyl phenylacetate, methyl salicylate, 4'-methylacetophenone, methylcyclopentenolone, 3-methylvaleric acid, pure mimosa, molasses, myristic acid, nerol, nerolidol, γ-nonalactone, nutmeg oil, δ-octalactone, octanal, octanoic acid, orange flower oil , orange oil, cassia tubular oil, palmitic acid, peppermint oil, oil

These flavors can be used singly or in combination to achieve the desired flavor.

The flavors dispersed in the adhesive 24 are fixed in the adhesive 24 prior to smoking and hardly volatilize from the adhesive 24 to the outside. On the other hand, when smoking, the mainstream smoke passes in close proximity to the adhesive 24. The flavoring agent fixed in the adhesive 24 escapes into the mainstream smoke due to the heat of the mainstream smoke or moisture (steam) contained in the mainstream smoke. This provides for a distinction between the aroma of the smoking article (smoking article) 11 prior to smoking and the aroma of the mainstream smoke during smoking, which may surprise the smoker. In addition, it may also take a predetermined time from the start of smoking until the flavor fixed in the adhesive 24 escapes into the mainstream smoke, i.e. there is a time delay from the start of smoking to the volatilization of the flavor, fixed in the adhesive 24, into the main stream of smoke.

The adhesive 24 may be uniformly mixed with a pigment such as a dye. Can be used, for example, a pigment such as food coloring. Examples of food colorings include, for example, natural pigments such as gardenia yellow, annatto, red pepper pigment, red cabbage pigment, monascus color, and gardenia blue, and synthetic pigments such as food red No. 2, food red No. 3, food red No. 102, Food Red #104, Food Red #105, Food Yellow #4, Food Yellow #5, Food Yellow #1, and Food Blue #2.

Next, the use of the cigarette 11 according to the present embodiment will be described. With the cigarette 11 of the present embodiment, the user ignites the tip of the aerosol generating rod 14, holds the mouth end 26 of the filter portion 15 in the mouth, and inhales, whereby the user can enjoy the aroma and taste of tobacco. In this case, the main stream of smoke mixes with the flavor contained in the liquid content of the capsule element 23, or the flavor evaporates from the adhesive 24, and the expected aroma and taste appear in the user's mouth. When the capsule element 23 is broken, the movement of the capsule element 23 is blocked, so that the user can easily break the capsule element 23 at the right time and enjoy the change in flavor and taste.

Next, the manufacturing method of the cigarette 11 will be described as an example of the smoking article of the present embodiment. The aerosol generating rod 14 is formed by wrapping a paper wrapper 13 around cut tobacco 12 in the usual manner. On the other hand, in the production line for the filter section 15, the filter section 15 manufacturing apparatus continuously in-line (sequentially) supplies the adhesive 24 to a position about the central axis C of the filter section 15 before the filter body 17 is completely rolled up into a cylindrical shape. At this time, the adhesive is in a molten state and heated to a temperature of 100 to 200°C. In addition, the device for manufacturing the filter portion 15, which is provided with the adhesive 24 as above, supplies the capsule member 23 to a location near the central axis C of the filter body 17. In addition, the filter portion 15 is fully formed into a cylinder, and hence the filter portion 15 remains at room temperature, which causes the adhesive 24 to cure. Thus, the position of the capsule element 23 with respect to the main body 17 of the filter is completely fixed.

Next, the movement prevention action of the capsule member 23 in the cigarette 11 will be described as an example of the smoking article of the present embodiment. Using the cigarette 11 of the present embodiment, a test was performed for seven subjects. In this test, the capsule element 23 was deliberately pushed into the oral cavity by biting the capsule element with the teeth. The test was carried out using the cigarette 11 of the present embodiment and a conventional cigarette as a comparative example in which the capsule body 23 and the filter body 17 were not glued. As a result, in the case of the conventional cigarette of the comparative example, one of the seven participants was able to push the capsule member 23 into the oral cavity. On the other hand, in the case of the cigarette 11 of the present embodiment, none of the seven participants could push the capsule member 23 into the mouth.

Since the capsule element 23 was deliberately pushed into the oral cavity during the tests, one

- 5 039604 of the seven participants was able to push the capsule element 23 into the oral cavity in the comparative example. However, in the normal use state, the probability that the capsule member 23 is pushed into the oral cavity even in the comparative example is considered to be very close to 0. In the present embodiment, even when the user tries to intentionally push the capsule member 23, the capsule member 23 cannot be moved to could be pushed out of the section 15 of the filter. Thus, it is possible to practically implement a cigarette 11 in which the capsule member 23 is unlikely to move.

According to the present embodiment, the smoking article comprises an aerosol generating rod 14 and a filter portion 15 adjacent to the aerosol generating rod 14, the filter portion 15 comprises a filter body 17, a capsule element 23 embedded in the filter body 17 and containing flavoring agent, and an adhesive 24, which connects the main part 17 of the filter and the capsule element 23.

In general, the fibers constituting the filter portion 15 extend in the axial direction (direction of the central axis C) of the filter portion 15. Therefore, when an external force is applied to the capsule element, in some rare cases, the capsule element may move along the direction in which the fibers run. However, since such an event occurs very rarely, it is nearly impossible for a manufacturer to acknowledge such an event as a problem. According to the above arrangement, by fixing the capsule element 23 on the filter body 17 with the adhesive 24, the displacement of the capsule element 23 from the position within the filter portion 15 can be prevented. As a result of this, it is possible to prevent the situation in which the capsule member 23 is displaced and cannot be broken easily, thereby being more convenient for the user.

Adhesive 24 is a thermoplastic resin. According to this arrangement, since the resin is fully cured when the product is supplied, the capsule element 23 can be prevented from moving to the filter portion 15, thereby achieving a smoking article in which the capsule element 23 can be easily destroyed. In addition, since moisture does not come out of the adhesive 24 during curing, the capsule member 23 can be prevented from being weakened by water.

The shell of the capsule element 23 is formed from a hydrophilic material, which softens when moisture is absorbed. In particular, the capsule shell of the capsule element 23 is formed from a material selected from starch, dextrin, polysaccharides, agar, gellan gum, gelatin, natural gelling agents, glycerin, sorbitol, calcium chloride, and mixtures thereof. According to the above arrangement, by using an adhesive that does not contain moisture, such as a thermoplastic adhesive, rather than using an adhesive that contains moisture, such as vinyl acetate slurry, the capsule member 23 is not weakened and it is prevented from being difficult to break.

The capsule element 23 is positioned on or near the central axis C of the filter section 15, and the adhesive 24 is linearly distributed along the central axis C on or near the central axis C of the filter section 15. According to this arrangement, even when the position of the capsule member 23 does not coincide with the position with respect to the direction of the central axis C due to manufacturing variation, since the adhesive 24 is distributed linearly along the central axis C, a slight displacement of the capsule member 23 can be tolerated, and the capsule member 23 can be securely fixed to section 15 of the filter.

The capsule element 23 is positioned at or near the central axis C of the filter portion 15, and a portion of the adhesive 24 is positioned in a cross-sectional view in the direction of the central axis C of the capsule element 23. According to this arrangement, the adhesive 24 can be placed in a superposition position on the capsule element 23. As a result of this the adhesive 24 is not applied to areas outside the capsule element 23. Thus, a problem such as poor adhesion between the capsule element 23 and the filter portion 15 can be prevented.

The adhesive 24 contains a fragrance. According to this arrangement, since a fragrance may be contained in the adhesive 24, it is not necessary to separately provide a cotton yarn or the like containing a fragrance in the filter portion 15. As a result, various flavors can be added to the mainstream smoke, which can reduce the degree of restriction when creating a product. In addition, the manufacturing method can be simplified and the production cost can be reduced as compared to the case of separately providing cotton yarn or the like containing fragrance.

The adhesive 24 contains a pigment. According to this arrangement, the adhesive 24 can be colored and the area where the adhesive 24 is cured can be different in color. In general, the color of this portion covered with adhesive 24 in filter portion 15 is essentially the same as the color of the portion not covered with adhesive 24 in filter portion 15. The portion of the filter portion 15 to which the adhesive 24 is applied is simply harder than the other portions. According to the arrangement mentioned above, it is certainly possible to improve the appearance at the place where the adhesive 24 is applied, so that limitations in the design of the smoking article can be reduced.

The capsule element 23 is positioned at a distance of less than 15 or 10 mm from the mouthpiece end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14.

- 6 039604 According to this arrangement, the capsule element 23 can be placed near the mouth end 26, and the flavorant can be placed in the mainstream of smoke at a position near the user's mouth. Thus, the capsule element 23 can be positioned at a location where the flavor can be delivered to the user's mouth most effectively. In addition, in the present embodiment, the capsule member 23 and the filter portion 15 are glued with the adhesive 24. Therefore, even in the above arrangement, the capsule member 23 can be prevented from falling out of the filter portion 15.

First modification.

Next, the smoking article (cigarette) according to the first modification of the present embodiment will be described. The first modification differs from the above embodiment in that the material of the capsule shell 22 of the capsule element 23 and the type of adhesive 24 are different, but the other parts are not changed. In the following, parts different from those of the above-described embodiment will be generally described, and descriptions of parts that are the same as those of the above-described embodiment will be omitted.

The capsule member 23 (capsule shell 22) is formed from a resin-based material (synthetic resin). More specifically, the capsule member 23 is formed from, for example, a polyethylene-based resin material, but may be formed from other types of resin-based materials (synthetic resins), such as polypropylene, polyurethane, polyvinyl chloride, and the like. The melting point of the capsule member 23, formed of, for example, polypropylene, is 104 to 120°C, which is lower than the melting point of a thermoplastic polymer (hot melt adhesive) of 150 to 180°C. Therefore, when a hot melt 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 by melting the resin-based thermoplastic resin.

In contrast to this embodiment, the adhesive 24 in this modification consists of a water-dispersed adhesive. The water-dispersed adhesive exhibits adhesion characteristics by evaporating water at normal temperature (room temperature). In this embodiment, as the adhesive 24 of the water-dispersed adhesives, for example, an adhesive based on an emulsion of a vinyl acetate polymer can be used.

The location of the adhesive 24 is similar to the position in the embodiment described above. In addition, as in the above embodiment, a fragrance may be mixed with the adhesive 24, and a pigment may be mixed with the adhesive 24. According to this modification, since the capsule member 23 is formed from a resin-based material, the strength of the capsule member 23 is improved, and the problem of unexpected destruction of the capsule member 23 during transportation or the like is prevented.

In this modification, the adhesive 24 is a water-dispersed adhesive. With this arrangement, an inexpensive and safe adhesive can be used as the adhesive 24. Thus, since the adhesive 24 is liquid at first, heating to melt the adhesive 24 is not necessary. Therefore, it is possible to prevent formation of holes in the capsule member 23 that may occur if the capsule member 23 is formed from a resin-based material or a heat-like adhesive 24 formed from a thermoplastic resin (hot melt adhesive) to melt the adhesive and apply the adhesive to the filter portion 15 and the capsule element 23.

The capsule shell 22 of the capsule element 23 is formed from a polymer resin material. According to this arrangement, when the water-dispersible adhesive is used as the adhesive 24, the capsule member 23 does not absorb moisture that diffuses (evaporates) from the water-dispersed adhesive, and it is possible to prevent the capsule member 23 from being difficult to break due to moisture.

The second filter section 31 is formed similarly to the filter section 15 according to this modification. The second section 31 of the filter differs from the section 15 of the filter in that it does not contain the capsule element 23, but other parts are similar to those of section 15 of the filter. In the present modification, the second filter section 31 consists of one integral part, but it may consist of two or more parts.

According to this modification, at least one second filter section 31 is provided between the aerosol-generating rod 14 and the filter portion 15. With this arrangement, even in the multi-filter cigarette 11, movement of the capsule member 23 relative to the filter portion 15 can be prevented, and a cigarette 11 in which the capsule member 23 can be easily broken can be practically implemented.

Third modification.

Further, as shown in FIG. 5, a smoking article (cigarette) according to the third modification of the present embodiment will be described. The third modification differs from the above embodiment in that the capsule member 23 is provided in a different position, but the other parts are the same as those of the above embodiment. Next, the parts different from those of the above-described embodiment will be mainly described, and descriptions of parts similar to those of the above-described embodiment will be omitted.

The layout of the filter section 15 is similar to that of this embodiment, except that the capsule element 23 is provided in a different position.

In other words, the capsule element 23 is provided in the middle section in the direction of the central axis C (longitudinal direction) of the filter section 15.

Even in the case where the capsule member 23 is provided in the middle portion in the longitudinal direction of the filter portion 15 as in the present modification, the movement of the capsule member 23 with respect to the filter portion 15 by the adhesive 24 can be prevented, which is more convenient for the user.

Fourth modification.

Next, shown in FIG. 6 is a smoking article according to the fourth modification of the present embodiment. In the fourth modification, the smoking article 41 is not a cigarette, but belongs to the field of so-called electronic cigarettes, in which the aerosol-generating rod 14 is heated by a so-called electric heater or the like. Next, the parts different from the parts of the above-described embodiment will be described in general, and the description of the parts that are similar to those of the above-described embodiment will be omitted. In FIG. 6 is a sectional view along a plane containing the central axis C showing the lower half of the shaft member 46 of the smoking article 41 and the body 45.

The smoking article 41 includes a main body 45 containing a battery 42, an electronic heating portion 43 and a recess 44, and a rod member 46 removably inserted into the recess 44 of the main body 45. The recess 44 is formed in the housing portion 45A of the main body 45. The battery 42 can be charged and depleted. The electronic heating section 43 is a so-called heater and has a heat generating element located around the recess 44. The heat generating element of the electric heating section 43 heats the aerosol generating rod 14 and causes the filler 61 of the aerosol generating rod 14 to release flavoring agent into the surrounding air. The heating temperature of the aerosol-generating rod 14 by the electric heating portion 43 is, for example, 400°C or less, which is much lower than the combustion temperature of a conventional ignition-type cigarette of 700 to 800°C. By heating at such a low temperature, the amount of mainstream smoke generated by the aerosol generating rod 14 is reduced compared to the cigarette 11 of the present embodiment. Therefore, the filtering function of the filter portion 15 of the present modification is preferably lower than that of the filter portion 15 of the cigarette 11 of the present embodiment, so that a preferable amount of mainstream smoke enters the user's mouth. In this modification, in order to reduce the filtering of the mainstream smoke of the filter section 15, the length of the filter section 15 in the direction of the central axis C is made smaller than in the above-described embodiment. It is also possible to shorten the length at which the main body of the filter is located from the entire length of the filter section and position a tube section or other segment with a low filtration rate of the mainstream smoke in the remaining section.

The stem element 46 is shaped like a cigarette. The rod element 46 includes a tubular cylindrical section 51, an aerosol generating rod 14 provided at one end section 51A of the cylindrical section 51, a filter section 15 provided at the other end section 51B opposite one end section 51A of the cylindrical section 51, a second filter section 31 located coaxially with the aerosol generating rod 14 at a position between the aerosol generating rod 14 and the filter section 15, and the tip paper member 16 connecting the cylindrical section 51, the aerosol generating rod 14 and the filter section 15.

The cylindrical portion 51 is formed of, for example, 100 to 300 µm thick paper in a cylindrical shape so as to have a predetermined stiffness. The tip paper member 16 is supported by the rigid cylindrical portion 51, and even when the stem member 46 is compressed in the direction of the central axis C, the tip paper member 16 does not collapse in the direction of the central axis C. The tip paper member 16 and the cylindrical portion 51 comprise a plurality of ventilation holes 53 in parts. outer periphery. A plurality of vents 53 extend through the tip paper member 16 and the cylindrical portion 51. The number of vents 53 is, for example, 10 to 40. The vents 53 are arranged, for example, in a circular row at the outer periphery of the cylindrical portion. The ventilation holes 53 are formed at regular intervals.

The aerosol-generating rod 14 includes a filler 61 containing cut tobacco 12 (crushed tobacco leaf), shredded homogenized tobacco, folded or peripherally rolled sheets of homogenized tobacco, folded homogenized tobacco or non-tobacco filler, and the like, and cigarette paper 54 wrapped around the filler 61. The cigarette paper 54 may be composed of paper alone, or may be formed of paper bonded to a high thermal conductivity metal foil such as aluminum foil or stainless steel foil.

The arrangement of the filter portion 15 is essentially the same as the other embodiments, except that the length of the filter body 17 in the direction of the central axis C is shorter. The filter portion 15 includes a filter body 17 of a cylindrical shape, a filter paper wrapper 21 wrapped around the filter body 17, a capsule element 23 which is embedded in the filter portion 15 (inside the filter body 17) and which accommodates the liquid contents containing the fragrance inside. capsule shell 22, and an adhesive 24 which connects the filter body 17 and the capsule element 23. The capsule element 23 is positioned at a distance of less than 10 mm from the mouth end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14. More preferably, the capsule element 23 is positioned at a distance of less than 6 mm from the mouth end 26 of the filter section 15 in the direction of the central axis C to the aerosol generating rod 14.

The second section 31 of the filter differs from the section 15 of the filter in that it does not contain the capsule element 23, but other parts are similar to those of section 15 of the filter. In the present modification, the second filter section 31 consists of one part, but it may consist of two or more parts. The filter section 15 and the second filter section 31 are connected by a second filter paper 62 .

According to the present modification, the same beneficial effects are achieved as in the above-described embodiment. Those. the user can enjoy the aroma and taste of the smoking article in the oral cavity by inhaling through the filter section 15 and the cylindrical section 51 while the rod member 46 is attached to the main body 45.

According to this modification, the smoking article 41 includes an electric heating section 43 for heating the aerosol generating rod 14. With this arrangement, in the smoking article 41, which belongs to the field of so-called electronic cigarettes, the destruction of the capsule element 23 can be further facilitated in the same way, which may be more convenient. for the user. In particular, in the case of using the electric heating portion 43, the length of the main filter portion 17 of the filter portion 15 tends to be short because the amount of smoke in the mainstream is small. With this modification, movement of the capsule element 23 can be prevented even in the short filter body 17 . As mentioned above, movement of the capsule member can be effectively prevented in a smoking article 41 with a short filter body 17 in which the possibility of the capsule member 23 falling out of the filter body 17 is high. This is extremely useful in product design.

The smoking article is not limited to the above embodiment and its modifications, and can be implemented by modifying the structural elements at the implementation stage without departing from the gist of the invention. Therefore, it is clear that the smoking article described above is applicable to smoking articles whereby the user enjoys the flavor of tobacco without being heated. In addition, some of these components may be removed from the components shown in these embodiments, or other modifications may be appropriately combined to carry out the present invention.
