- saccharides e.g.
- a solvent suitable to the flavorant can be used.
- MCT medium chain fatty acid triglyceride
- propylene glycol propylene glycol
- water water
- ethanol a solvent suitable to the flavorant
- the content liquid may contain other solvents, and other additives such as a pigment, an emulsifier, and a thickener.
- the manufacturing method of the capsule member 23 is not limited to any particular one, the falling-dropping method may be used for manufacturing a capsule member 23 having a seamless capsule shell 22 .
- This method employs a double nozzle. The content liquid is ejected from the inner side nozzle, and simultaneously a liquid material formed of the capsule shell 22 is ejected from the outer side nozzle. As a result, the liquid material formed of the capsule shell 22 can encapsulate the content liquid without forming any seam.
- the capsule member 23 may be in the form of a sphere or a cylinder.
- the sphere includes a round object having a substantially circular section and an ellipsoidal object having an ellipsoidal section.
- the capsule member 23 is an object having a substantially circular section. If the capsule member 23 is a sphere having a substantially circular section, it may have a diameter, for example, of 1.0 to 8.0 mm. In the case of an ellipsoid, the capsule member 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 member 23 may have a diameter of 1.0 to 8.0 mm and a height of 1.0 to 8.0 mm.
- a capsule having a diameter smaller than 7.5 to 8.0 mm, which is the diameter of the commonly distributed cigarette and filter portion, should be used.
- a capsule member having a diameter of 3.0 mm to 4.5 mm 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, problems may arise; for example, the amount of the flavorant applied to the cigarette may be reduced, thereby reducing the feeling of satisfaction that can be imparted by the flavorant; and it may be difficult to find the presence of the capsule, when the smoker breaks the capsule.
- the ratio of the cross-sectional area of the capsule to the cross-sectional area of the filter body is increased, so that the ventilation resistance of the filter portion when the capsule is not crushed becomes too large, causing the smoker to feel difficulty in inhaling.
- the filter body 17 can be formed of a filter material of a cellulose acetate fiber bundle (acetate tow), as in the case of a conventional filter cigarette.
- the filter body 17 may comprise only a filter material of acetate tow, or may comprise a filter material of acetate tow and the filter wrapping paper 21 wrapped around the filter material. If the filter portion 15 includes a plurality of filter bodies 17 , the filter body 17 on the cut tobacco 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.
- the acetate tow may have a filament denier of 1.9 to 12.0 (g/9000 m), a total denier of 10,000 to 44,000 (g/9000 m), a fiber number of 830 to 23,500 (fibers), and a pressure drop of 100 to 600 (mmH 2 0/120 mm).
- the filament denier, the total denier, and the number of fibers should be designed to achieve the target value of ventilation resistance, depending on the setting circumference (14.0 to 26.0 (mm)) of the filter body.
- a plasticizer such as triacetin may be added to the acetate tow.
- the plasticizer may be added in an amount of 5 to 12% by weight relative to the weight of the acetate tow. If activated charcoal is added in a dispersed manner between the fibers of the acetate tow, the plasticizer may be added in an amount of 2 to 12% by weight relative to the weight of the acetate tow.
- the filter portion 15 may have a circumference of about 14 to 26 mm, and a length, for example, of 17 to 40 mm, like a conventional filter.
- the aerosol generating rod 14 like the conventional cigarette 11 , comprises the cut tobacco 12 and the cigarette paper 13 wrapped around the cut tobacco, and may have, for example, a circumference of about 14 to 26 mm and a length of about 20 to 70 mm.
- the adhesive 24 is provided over the entire length of the filter portion 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 portion 15 along the central axis C of the filter portion 15 . Since the capsule member 23 is located on or near the central axis C, a part of the adhesive 24 is positioned within the projection section in the direction of the central axis C of the capsule member 23 .
- the adhesive 24 bonds the capsule member 23 and the filter 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 formed of a thermoplastic resin (hot-melt adhesive).
- hot-melt adhesive When the adhesive 24 is applied to the filter portion 15 , it becomes liquefied by heating to a high temperature of 100 to 200° C. However, at the time of product shipment, the adhesive 24 is completely solid.
- the adhesive 24 is applied continuously and linearly to filter tow at a rate of 10 to 50 mg per 120 mm length in the longitudinal direction of the filter body 17 .
- the adhesive 24 may cover 1/20 to 1 ⁇ 3 of the total surface area of the capsule member 23 , for example.
- the area covering the surface of the capsule member 23 is preferably 1 ⁇ 2 or less, for example. If 1 ⁇ 2 or more of the capsule member 23 is covered with the adhesive 24 , the capsule member 23 becomes too hard to be crushed by fingers, since the adhesive 24 functions as a kind of a coating.
- Flavorants may be uniformly added to the adhesive 24 .
- the preferable amount of the flavor components is the amount that does not cause deterioration of the function of the adhesive 24 .
- the amount of the flavorants uniformly contained within the adhesive 24 can be adjusted appropriately, for example, by increasing or decreasing the amount of the flavorants to be added for flavoring the mainstream smoke of the cigarette 11 (smoking article).
- flavor components may be dispersed directly in the adhesive 24 , or the flavor components may be included in an inclusion compound such as dextrin, ⁇ -cyclodextrin, and ⁇ -cyclodextrin, and the inclusion compound may be dispersed in the adhesive 24 .
- an inclusion compound such as dextrin, ⁇ -cyclodextrin, and ⁇ -cyclodextrin
- Examples of the flavorants added to the adhesive 24 include the following. Examples include 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 absolute, ⁇ -carotene, carrot juice, L-carvone, ⁇ -caryophyllene, cassia bark oil, cedarwood oil, celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acids, cin
- flavorants may be used alone, or in combination to achieve a desired scent.
- the flavorant dispersed within the adhesive 24 are fixed to the adhesive 24 before smoking, and volatilization to the outside of the adhesive 24 occurs almost not at all.
- mainstream smoke passes through the vicinity of the adhesive 24 .
- the flavorant fixed to the adhesive 24 is volatilized into the mainstream smoke by the heat of the mainstream smoke or the moisture (vapor) contained in the mainstream smoke. This provides a gap between the scent of the smoking article (smoking article) 11 before smoking and the scent of the mainstream smoke during smoking, which can be surprising to the smoker.
- the adhesive 24 can be uniformly mixed with a pigment such as a dye or a colorant.
- a pigment such as a dye or a colorant.
- an edible pigment may be used, for example.
- edible pigments include, for example, natural pigments, such as a gardenia yellow pigment, an annatto pigment, a capsicum pigment, a red cabbage pigment, a monascus pigment, and a gardenia blue pigment, and synthetic pigments, such as food red No. 2, food red No. 3, food red No. 102, food red No 104, food red No. 105, food yellow No. 4, food yellow No. 5, food blue No. 1, and food blue No. 2.
- the user ignites the tip of the aerosol generating rod 14 , holds the mouthpiece end 26 of the filter portion 15 in the mouth and inhales, whereby the user can enjoy the flavor and taste of the tobacco.
- the mainstream smoke is mixed with the fragrant contained in the content liquid of the capsule member 23 or the fragrant volatilized from the adhesive 24 , and the expected flavor and taste is exhibited in the oral cavity of the user.
- the capsule member 23 is crushed, the movement of the capsule member 23 is inhibited, so that the user can easily crush the capsule member 23 at a desired timing and enjoy the changed flavor and taste.
- the aerosol generating rod 14 is formed by wrapping the wrapping paper 13 around the cut tobacco 12 in the conventional manner.
- the manufacturing apparatus of the filter portion 15 continuously in a straight line (linearly) supplies the adhesive 24 to a position near the central axis C of the filter portion 15 before the filter body 17 is completely converged into a cylindrical shape.
- the adhesive is in a molten state, heated at 100 to 200° C.
- the manufacturing apparatus of the filter portion 15 which is provided with the adhesive 24 as mentioned above, supplies the capsule member 23 to the vicinity of the central axis C of the filter body 17 .
- the filter portion 15 is completely formed into a cylinder shape, and thereafter the filter portion 15 is left at room temperature, with the result that the adhesive 24 is solidified.
- the position of the capsule member 23 with respect to the filter body 17 is completely fixed.
- the inventors conducted a test on seven subjects.
- the capsule member 23 was intentionally pushed into the oral cavity by biting the capsule member with the teeth.”
- the test was conducted using the cigarette 11 of the present embodiment, and a conventional cigarette as a comparative example in which the capsule member 23 and the filter body 17 were not bonded.
- the conventional cigarette of the comparative example one of the seven subjects was able to push the capsule member 23 into the oral cavity.
- none of the seven subjects was able to push the capsule member 23 into the oral cavity.
- the capsule member 23 was intentionally pushed into the oral cavity” in the test, one of the seven subjects was able to push the capsule member 23 into the oral cavity in the comparative example.
- the possibility that the capsule member 23 is pushed out into the oral cavity even in the comparative example is considered to be very close to 0.
- the capsule member 23 could not be moved to be pushed out from the filter portion 15 .
- the smoking article includes the aerosol generating rod 14 , and the filter portion 15 adjacent to the aerosol generating rod 14 , the filter portion 15 including the filter body 17 , the capsule member 23 embedded in the filter body 17 and containing a flavorant, and the adhesive 24 that bonds the filter body 17 and the capsule member 23 .
- the fibers constituting the filter portion 15 extend in the axial direction (the direction of the central axis C) of the filter portion 15 . Therefore, when an external force is applied to a capsule member, in some rare cases, the capsule member may move to be displaced along the direction in which the fibers extend. However, since such an event occurs very rarely, it was almost impossible for the manufacturer to recognize the event as a problem. According to the above configuration, by fixing the capsule member 23 to the filter body 17 with the adhesive 24 , the capsule member 23 can be prevented from being out of position within the filter portion 15 . As a result, it is possible to prevent a situation in which the capsule member 23 moves to be displaced and cannot be easily crushed, thereby improving the convenience of the user.
- the adhesive 24 is a thermoplastic resin. According to this configuration, since the resin is completely solidified when the product is shipped, it is possible to prevent the capsule member 23 from moving in the filter portion 15 , thereby realizing a smoking article in which the capsule member 23 can be easily crushed. Further, 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 capsule shell of the capsule member 23 is formed of a hydrophilic material which is weakened by water absorption.
- the capsule shell 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.
- an adhesive that does not contain moisture such as a thermoplastic adhesive
- an adhesive that contains moisture such as vinyl acetate paste
- the capsule member 23 is positioned on or near the central axis C of the filter portion 15 , and the adhesive 24 linearly extends along the central axis C on or near the central axis C of the filter portion 15 . According to this configuration, even when the position of the capsule member 23 is out of position with respect to the direction of the central axis C due to manufacturing variations, since the adhesive 24 extends linearly along the central axis C, a slight displacement of the capsule member 23 can be allowed, and the capsule member 23 can be reliably fixed to the filter portion 15 .
- the capsule member 23 is positioned on or near the central axis C of the filter portion 15 , and a part of the adhesive 24 is positioned in a projected section in the direction of the central axis C of the capsule member 23 .
- the adhesive 24 can be disposed at a position overlapping the capsule member 23 .
- the adhesive 24 is not applied to a position away from the capsule member 23 .
- the adhesive 24 includes a flavorant. According to this configuration, since the flavorant can be contained in the adhesive 24 , it is not necessary to separately provide cotton yarn or the like containing the flavorant 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. Furthermore, the manufacturing process can be simplified and the manufacturing cost can be reduced as compared with the case of separately providing cotton yarn or the like containing the flavorant.
- the adhesive 24 includes a pigment. According to this configuration, the adhesive 24 can be colored, and the portion where the adhesive 24 is solidified can be decorated. Generally, the color of the portion coated with the adhesive 24 in the filter portion 15 is not substantially different from the color of the portion not coated with the adhesive 24 in the filter portion 15 .
- 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 configuration, it is possible to positively contribute to the improvement of the appearance at the place where the adhesive 24 is applied, so that the freedom of the smoking article design can be improved.
- the capsule member 23 is positioned at a distance shorter than 15 mm or 10 mm from the mouthpiece end 26 of the filter portion 15 in the direction of the center axis C toward the aerosol generating rod 14 . According to this configuration, it is possible to place the capsule member 23 near the mouthpiece end 26 , and the flavorant can be put on the mainstream smoke at a position close to the mouth of the user. Thus, the capsule member 23 can be arranged at a position where the flavorant can be delivered to the user's oral cavity most efficiently. Further, in the present embodiment, the capsule member 23 and the filter portion 15 are bonded by the adhesive 24 . Therefore, even in the arrangement mentioned above, it is possible to prevent the capsule member 23 from falling off the filter portion 15 .
- the first modification is different from the above embodiment in that the material of the capsule shell 22 of the capsule member 23 and the type of the adhesive 24 are different, but other parts are the same.
- the parts different from those of the above-described embodiment will be mainly described, and descriptions of the parts that are the same as those of the above-described embodiment will be omitted.
- the capsule member 23 (capsule shell 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 other kinds of resin materials (synthetic resin materials), such as polypropylene, polyurethane, polyvinyl chloride, and the like.
- the melting point of the capsule member 23 formed of polypropylene for example, 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, when the 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 thermoplastic resin is melted.
- the adhesive 24 of this modification is composed of an aqueous dispersion adhesive.
- the aqueous dispersion adhesive exhibits an adhesive performance by evaporation of the water at normal temperature (room temperature).
- a vinyl acetate resin emulsion adhesive among the aqueous dispersion adhesives can be suitably used as the adhesive 24 .
- the arrangement of the adhesive 24 is the same as that of the embodiment described above. Also, as well as the embodiment described above, a flavorant may be mixed with the adhesive 24 , and the pigment may be mixed with the adhesive 24 . 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 wherein the capsule member 23 is unexpectedly crushed or the like during transportation is prevented.
- the adhesive 24 is an aqueous dispersion adhesive.
- an inexpensive and safe adhesive can be used as the adhesive 24 .
- the adhesive 24 is a liquid from the beginning, it is not necessary to apply heat to melt the adhesive 24 . Therefore, it is possible to prevent holes from being formed in the capsule member 23 , which may be formed if the capsule member 23 is formed of a resin material or the like by heating the adhesive 24 formed of a thermoplastic resin (hot-melt adhesive) to melt the adhesive and applying the adhesive to the filter portion 15 and the capsule member 23 .
- a thermoplastic resin hot-melt adhesive
- the capsule shell 22 of the capsule member 23 is formed of a resin material. According to this configuration, when the aqueous dispersion adhesive is used as the adhesive 24 , the capsule member 23 does not absorb the moisture that is diffused (volatilized) from the aqueous dispersion adhesive, and it is possible to prevent the situation wherein the capsule member 23 is difficult to crush due to the moisture.
- a smoking article (cigarette) according to a second modification of the embodiment will be described.

Abstract
Description
- This application is a Continuation Application of PCT Application No. PCT/JP2017/047022, filed Dec. 27, 2017, the entire contents of which are incorporated herein by reference.
- The present invention relates to a smoking article including a capsule member.
- A smoking article with a filter, for example, a conventional filter cigarette, includes a filter portion, tobacco portion, and a tipping paper member. The filter portion is formed in a rod shape by wrapping with filter wrapping paper a filter body containing a cellulose acetate fiber bundle or a filter body formed of a nonwoven fabric containing a pulp. The tobacco portion is formed in a rod shape by wrapping dried tobacco leaves with cigarette paper. The filter portion and the tobacco portion are joined end to end. The filter portion and the tobacco portion are wrapped with the tipping paper member over the entire circumferences to adhere to each other to form one integral body.
- Conventionally, as disclosed in Japanese Patent No. 6078657, for example, a flavor capsule is incorporated into a cigarette filter body. A smoker crushes the flavor capsule with fingers to inhale the flavor produced from the content in the flavor capsule at the time of smoking or to mask the smell of the cigarette butt left after the cigarette is extinguished. The details of the flavor capsule are described in Jpn. PCT National Publication No. 2007-520204, for example.
- Besides 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 a tobacco material. Also, there are many smoking articles which generate a fragrance component by heating an aerosol generating rod containing an aerosol base material such as a tobacco material, a flavor component, and a glycerin without combustion. As methods of heating without combustion, there are various methods that can be used depending on the required level, such as heating by electrical resistance, IH, chemical change, or phase change.
- The aerosol generating rod includes a tobacco rod formed by wrapping dried tobacco leaves with a cigarette paper and formed into a rod shape. In addition, the aerosol generating rod includes a rod formed by wrapping dried tobacco leaves with a cigarette sheet, and a rod formed by impregnating a base material other than the tobacco leaves with an aerosol source such as glycerin and a fragrance component and thereafter wrapping the base material with paper into a rod shape. In any shape, the aerosol generating rod is substantially cylindrical, and generally a filter portion is arranged at and connected to one end of the aerosol generating rod by wrapping with a tipping paper.
- Examples of smoking articles in which a fragrance component is generated by heating the aerosol generating rod without combustion are disclosed in Japanese Patent No. 5990500 and Japanese Patent No. 5292410.
- According to the present invention, a smoking article includes an aerosol generating rod, and a filter portion disposed adjacent to the aerosol generating rod. The filter portion includes a filter body, a capsule member, and an adhesive. The capsule member contains a flavorant inside and is embedded in the filter body. The adhesive bonds the filter body and the capsule member.
- Advantages of the invention will be set forth in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Advantages of the invention may be realized and obtained by means of the instrumentalities and combinations particularly pointed out hereinafter.
- The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention, and together with the general description given above and the detailed description of the embodiments given below, serve to explain the principles of the invention.
-
FIG. 1 is a front view of a cigarette as an example of a smoking article according to an embodiment. -
FIG. 2 is a sectional view of the cigarette taken along a central axis C shown inFIG. 1 . -
FIG. 3 is a sectional view of the cigarette taken along line F3-F3 shown inFIG. 2 . -
FIG. 4 is a sectional view of a smoking article (cigarette) taken along a central axis C according to a first modification. -
FIG. 5 is a sectional view of a smoking article (cigarette) taken along a central axis C according to a second modification. -
FIG. 6 is a sectional view of a smoking article taken along a central axis C according to a third modification. - An embodiment of a cigarette, which is an example of a smoking article, will now be described. The smoking article includes a cigarette, a cigar, a hand-rolled cigarette, a cigarillo, and a smoking tool (electronic cigarette) that allows a user to inhale a fragrance of tobacco by heating the tobacco by a heater or the like or steaming the tobacco by steam, a smoking tool that allows a user to inhale a fragrance of tobacco by heating with a carbon heat source, or the like, and a non-heating type smoking tool that allows a user to inhale a fragrance of tobacco.
- As shown in
FIGS. 1 and 2 , acigarette 11 includes anaerosol generating rod 14 including cut tobacco 12 (shredded leaves, tobacco) andcigarette paper 13 wrapped around the cuttobacco 12, afilter portion 15 disposed adjacent to theaerosol generating rod 14, and atipping paper member 16 wrapped around theaerosol generating rod 14 and thefilter portion 15 so as to connect theaerosol generating rod 14 to thefilter portion 15. A central axis C passing through the center of theaerosol generating rod 14 and the center of thefilter portion 15 can be defined in thecigarette 11. - The
filter portion 15 includes afilter body 17 having a cylindrical shape, afilter wrapping paper 21 wrapped around thefilter body 17, acapsule member 23 that is embedded within the filter portion 15 (within the filter body 17) and that holds a content liquid containing flavorant inside acapsule shell 22, and anadhesive 24 that bonds thefilter body 17 and thecapsule member 23. - The tipping
paper member 16 which wraps thefilter portion 15 may or may not be provided with a plurality of vents on a part of the outer periphery. In the case where the vents are provided, the number of the vents may be, for example, 10 to 40. In this case, the plurality of vents are arranged in a row in an annular shape, for example, in an outer peripheral part of the tippingpaper member 16 wrapped around thefilter portion 15. The plurality of vents are formed at substantially regular intervals. With the plurality of vents, air is drawn into thefilter portion 15 through the vents when the user smokes. Diluting mainstream smoke with ambient air flowing through the vents allows a product design with a desired tar value. - As shown in
FIG. 2 , thecigarette 11 includes theaerosol generating rod 14 including the cuttobacco 12, and thecigarette paper 13 wrapped around the cuttobacco 12, thefilter portion 15, and thetipping paper member 16 disposed on theaerosol generating rod 14 and thefilter portion 15 so as to connect theaerosol generating rod 14 to thefilter portion 15. - The
capsule member 23 is embedded in thefilter body 17. The number of thecapsule members 23 in thefilter portion 15 may be one or more (for example, 2 to 10). Thecapsule member 23 is provided on or near the central axis C of thefilter portion 15. Thecapsule member 23 is positioned at a distance of 15 mm or shorter from amouthpiece end 26 of thefilter portion 15 in the direction of the central axis C toward theaerosol generating rod 14. Preferably, thecapsule member 23 is positioned at a distance shorter than 10 mm from themouthpiece end 26 of thefilter portion 15 in the direction of the central axis C toward theaerosol generating rod 14. More preferably, thecapsule member 23 is positioned at a distance of 7 mm or shorter from themouthpiece end 26 of thefilter portion 15 in the direction of the central axis C toward theaerosol generating rod 14. By adopting this arrangement, the user can easily crush thecapsule member 23 not only with fingers, but by biting thecapsule member 23 with teeth during smoking. Furthermore, since the fragrance generating source is close to the mouthpiece end, the smoker can enjoy a stronger flavor sensation. - The
capsule member 23 includes thecapsule shell 22, and a content liquid encapsulated in thecapsule shell 22 and containing a flavorant. Thecapsule 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 a flavorant and a coloring agent. Thecapsule member 23 is preferably colored so as to be recognizable by the smoker when thecapsule member 23 is crushed, even though it is surrounded by opaquefilter wrapping paper 21 and tippingpaper member 16. Thecapsule shell 22 preferably contains a coloring agent, such as Blue No. 1. If thecapsule shell 22 of thecapsule member 23 contains a hydrophilic material, it may be considered that thecapsule shell 22 is composed of a material weakened by water absorption. - As the flavorant of the content liquid, any flavorant for a smoking article such as menthol, plant essential oil, etc. may be used. Main examples of the flavorant include menthol, leaf tobacco extract; natural plant flavors (e.g., cinnamon, sage, herb, chamomile, pueraria lobata, sweet hydrangea leaf, clove, lavender, cardamom, caryophyllus, nutmeg, bergamot, geranium, honey essence, rose oil, lemon, orange, cassia bark, caraway, jasmine, ginger, coriander, vanilla extract, spearmint, peppermint, cassia, coffee, celery, cascarilla, sandalwood, cocoa, ylang ylang, fennel, anise, licorice, St John's bread, prune extract, and peach extract), saccharides (e.g., glucose, fructose, isomerized saccharide, and caramel), cocoa (e.g., powder and extract), esters (e.g., isoamyl acetate, linalyl acetate, isoamyl propionate, and linalyl butyrate), ketones (e.g., menthone, ionone, damascenone, and ethyl maltol), alcohols (e.g., geraniol, linalool, anethole, and eugenol), aldehydes (e.g., vanillin, benzaldehyde, and anisaldehyde), lactones (e.g., γ-undecalactone and γ-nonalactone), animal flavorants (e.g., musk, ambergris, civet, and castoreum), and hydrocarbons (e.g., limonene and pinene). These flavorants may be used alone or in combination.
- As a solvent of the content liquid, a solvent suitable to the flavorant can be used. For example, medium chain fatty acid triglyceride (MCT) (specifically, capryl/capric acid glycerin), propylene glycol, water, or ethanol may be used. The content liquid may contain other solvents, and other additives such as a pigment, an emulsifier, and a thickener.
- Although the manufacturing method of the
capsule member 23 is not limited to any particular one, the falling-dropping method may be used for manufacturing acapsule member 23 having aseamless capsule shell 22. This method employs a double nozzle. The content liquid is ejected from the inner side nozzle, and simultaneously a liquid material formed of thecapsule shell 22 is ejected from the outer side nozzle. As a result, the liquid material formed of thecapsule shell 22 can encapsulate the content liquid without forming any seam. - The
capsule member 23 may be in the form of a sphere or a cylinder. The sphere includes a round object having a substantially circular section and an ellipsoidal object having an ellipsoidal section. Preferably, thecapsule member 23 is an object having a substantially circular section. If thecapsule member 23 is a sphere having a substantially circular section, it may have a diameter, for example, of 1.0 to 8.0 mm. In the case of an ellipsoid, thecapsule member 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, thecapsule member 23 may have a diameter of 1.0 to 8.0 mm and a height of 1.0 to 8.0 mm. When a spherical capsule member is applied to a generally distributed cigarette, a capsule having a diameter smaller than 7.5 to 8.0 mm, which is the diameter of the commonly distributed cigarette and filter portion, should be used. When a spherical capsule member is applied to a generally distributed cigarette, 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, problems may arise; for example, the amount of the flavorant applied to the cigarette may be reduced, thereby reducing the feeling of satisfaction that can be imparted by the flavorant; and it may be difficult to find the presence of the capsule, when the smoker breaks the capsule. 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 is increased, so that the ventilation resistance of the filter portion when the capsule is not crushed becomes too large, causing the smoker to feel difficulty in inhaling. - The
filter body 17 can be formed of a filter material of a cellulose acetate fiber bundle (acetate tow), as in the case of a conventional filter cigarette. Thefilter body 17 may comprise only a filter material of acetate tow, or may comprise a filter material of acetate tow and thefilter wrapping paper 21 wrapped around the filter material. If thefilter portion 15 includes a plurality offilter bodies 17, thefilter body 17 on thecut tobacco 12 side and thefilter body 17 on the mouthpiece side may have the same material and structure, or may have different materials and structures. - The acetate tow may have a filament denier of 1.9 to 12.0 (g/9000 m), a total denier of 10,000 to 44,000 (g/9000 m), a fiber number of 830 to 23,500 (fibers), and a pressure drop of 100 to 600 (mmH20/120 mm). The filament denier, the total denier, and the number of fibers should be designed to achieve the target value of ventilation resistance, depending on the setting circumference (14.0 to 26.0 (mm)) of the filter body. A plasticizer such as triacetin may be added to the acetate tow. The plasticizer may be added in an amount of 5 to 12% by weight relative to the weight of the acetate tow. If activated charcoal is added in a dispersed manner between the fibers of the acetate tow, the plasticizer may be added in an amount of 2 to 12% by weight relative to the weight of the acetate tow.
- For example, the
filter portion 15 may have a circumference of about 14 to 26 mm, and a length, for example, of 17 to 40 mm, like a conventional filter. - The
aerosol generating rod 14, like theconventional cigarette 11, comprises thecut tobacco 12 and thecigarette paper 13 wrapped around the cut tobacco, and may have, for example, a circumference of about 14 to 26 mm and a length of about 20 to 70 mm. - The adhesive 24 is provided over the entire length of the
filter portion 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 thefilter portion 15 along the central axis C of thefilter portion 15. Since thecapsule member 23 is located on or near the central axis C, a part of the adhesive 24 is positioned within the projection section in the direction of the central axis C of thecapsule member 23. The adhesive 24 bonds thecapsule member 23 and thefilter 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 formed of a thermoplastic resin (hot-melt adhesive). When the adhesive 24 is applied to thefilter portion 15, it becomes liquefied by heating 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 thefilter portion 15, the adhesive 24 is applied continuously and linearly to filter tow at a rate of 10 to 50 mg per 120 mm length in the longitudinal direction of thefilter body 17. As shown inFIG. 3 , the adhesive 24 may cover 1/20 to ⅓ of the total surface area of thecapsule member 23, for example. The area covering the surface of thecapsule member 23 is preferably ½ or less, for example. If ½ or more of thecapsule member 23 is covered with the adhesive 24, thecapsule member 23 becomes too hard to be crushed by fingers, since the adhesive 24 functions as a kind of a coating. - Flavorants may be uniformly added to the adhesive 24. In the case of uniformly adding the flavor components to the adhesive 24, it is considered that the preferable amount of the flavor components is the amount that does not cause deterioration of the function of the adhesive 24. The amount of the flavorants uniformly contained within the adhesive 24 can be adjusted appropriately, for example, by increasing or decreasing the amount of the flavorants to be added for flavoring the mainstream smoke of the cigarette 11 (smoking article).
- These flavor components may be dispersed directly in the adhesive 24, or the flavor components may be included in an inclusion compound such as dextrin, α-cyclodextrin, and β-cyclodextrin, and the inclusion compound may be dispersed in the adhesive 24. By adopting such a technique, it is also possible to reduce the influence on the adhesive force of the adhesive 24 by dispersing the flavor components in the adhesive 24.
- Examples of the flavorants added to the adhesive 24 include the following. Examples include 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 absolute, β-carotene, carrot juice, L-carvone, β-caryophyllene, cassia bark oil, cedarwood oil, celery seed oil, chamomile oil, cinnamaldehyde, cinnamic acids, cinnamyl alcohol, cinnamyl cinnamate, citronella oil, DL-citronellol, clary sage extract, cocoa, coffees, cognac oil, coriander oil, cuminaldehyde, davana oil, δ-decalactone, γ-decalactone, decanoic acid, dill herb oil, 3,4-dimethyl-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 phenylacetate, ethyl propionate, ethyl stearate, 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, fenugreek absolute, genet absolute, gentian root infusion, geraniol, geranylacetate, grape juice, guaiacol, guava extract, γ-heptalactone, γ-hexalactone, hexanoic acid, cis-3-hexan-1-ol, hexyl acetate, hexyl alcohol, hexyl phenylacetate, honey, 4-hydroxy-3-pentenoic acid lactone, 4-hydroxy-4-(3-hydroxy-1-butenyl)-3,5,5-trimethyl-2-cyclohexane-1-on, 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 tincture, labdanum oil, lemon-terpeneless oil, licorice extract, linalool, linalyl acetate, lovage root oil, maltol, maple syrup, menthol (L-menthol), menthone, L-menthyl acetate, para-methoxybenzaldehyde, methyl-2-pyrrolylketone, methyl anthranilate, methyl phenylacetate, methyl salicylate, 4′-methylacetophenone, methylcyclopentenolone, 3-methylvaleric acid, mimosa absolute, molasses, 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 paraguai oil, phenethyl alcohol, phenethyl phenylacetate, phenylacetic acid, piperonal, plum extract, propenyl guaethol, propyl acetate, 3-propylidenphthalide, prune juice, pyruvate, raisin extract, rose oil, rum, sage oil, sandalwood oil, spearmint oil, styrax 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, trimethylcitrate, 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-1,3-cyclohexadienyl)2-butene-4-one, 2,3,5-trimethylpyrazine, γ-undecalactone, γ-valerolactone, vanilla extract, vanillin, veratraldehyde, and violet leaf absolute.
- These flavorants may be used alone, or in combination to achieve a desired scent.
- The flavorant dispersed within the adhesive 24 are fixed to the adhesive 24 before smoking, and volatilization to the outside of the adhesive 24 occurs almost not at all. On the other hand, when smoking, mainstream smoke passes through the vicinity of the adhesive 24. The flavorant fixed to the adhesive 24 is volatilized into the mainstream smoke by the heat of the mainstream smoke or the moisture (vapor) contained in the mainstream smoke. This provides a gap between the scent of the smoking article (smoking article) 11 before smoking and the scent of the mainstream smoke during smoking, which can be surprising to the smoker. Further, it is also possible to take a predetermined time from the start of smoking until the fragrant fixed in the adhesive 24 volatilizes into the mainstream smoke, that is, to give a time lag from the start of smoking before the fragrant fixed in the adhesive 24 volatilizes into the mainstream smoke.
- The adhesive 24 can be uniformly mixed with a pigment such as a dye or a colorant. As such a pigment, an edible pigment may be used, for example. Examples of edible pigments include, for example, natural pigments, such as a gardenia yellow pigment, an annatto pigment, a capsicum pigment, a red cabbage pigment, a monascus pigment, and a gardenia blue pigment, and synthetic pigments, such as food red No. 2, food red No. 3, food red No. 102, food red No 104, food red No. 105, food yellow No. 4, food yellow No. 5, food blue No. 1, and food blue No. 2.
- Functions of the
cigarette 11 according to the present embodiment will now be described. With thecigarette 11 of the present embodiment, the user ignites the tip of theaerosol generating rod 14, holds themouthpiece end 26 of thefilter portion 15 in the mouth and inhales, whereby the user can enjoy the flavor and taste of the tobacco. At this time, the mainstream smoke is mixed with the fragrant contained in the content liquid of thecapsule member 23 or the fragrant volatilized from the adhesive 24, and the expected flavor and taste is exhibited in the oral cavity of the user. When thecapsule member 23 is crushed, the movement of thecapsule member 23 is inhibited, so that the user can easily crush thecapsule member 23 at a desired timing and enjoy the changed flavor and taste. - Next, a process of producing the
cigarette 11 as an example of the smoking article of the present embodiment will be described. Theaerosol generating rod 14 is formed by wrapping the wrappingpaper 13 around thecut tobacco 12 in the conventional manner. On the other hand, in the production line of thefilter portion 15, the manufacturing apparatus of thefilter portion 15 continuously in a straight line (linearly) supplies the adhesive 24 to a position near the central axis C of thefilter portion 15 before thefilter body 17 is completely converged into a cylindrical shape. At this time, the adhesive is in a molten state, heated at 100 to 200° C. In addition, the manufacturing apparatus of thefilter portion 15, which is provided with the adhesive 24 as mentioned above, supplies thecapsule member 23 to the vicinity of the central axis C of thefilter body 17. Further, thefilter portion 15 is completely formed into a cylinder shape, and thereafter thefilter portion 15 is left at room temperature, with the result that the adhesive 24 is solidified. Thus, the position of thecapsule member 23 with respect to thefilter body 17 is completely fixed. - Next, the movement preventing action of the
capsule member 23 in thecigarette 11 as an example of the smoking article of the present embodiment will be described. Using thecigarette 11 of the present embodiment, the inventors conducted a test on seven subjects. In the test, “thecapsule member 23 was intentionally pushed into the oral cavity by biting the capsule member with the teeth.” The test was conducted using thecigarette 11 of the present embodiment, and a conventional cigarette as a comparative example in which thecapsule member 23 and thefilter body 17 were not bonded. As a result, in the case of the conventional cigarette of the comparative example, one of the seven subjects was able to push thecapsule member 23 into the oral cavity. On the other hand, in the case of thecigarette 11 according to the present embodiment, none of the seven subjects was able to push thecapsule member 23 into the oral cavity. - Since “the
capsule member 23 was intentionally pushed into the oral cavity” in the test, one of the seven subjects was able to push thecapsule member 23 into the oral cavity in the comparative example. However, in the normal state of use, the possibility that thecapsule member 23 is pushed out into the oral cavity even in the comparative example is considered to be very close to 0. According to the present embodiment, even when the user tried to intentionally push out thecapsule member 23, thecapsule member 23 could not be moved to be pushed out from thefilter portion 15. Thus, it is possible to realize thecigarette 11 in which thecapsule member 23 is unlikely to move. - According to the present embodiment, the smoking article includes the
aerosol generating rod 14, and thefilter portion 15 adjacent to theaerosol generating rod 14, thefilter portion 15 including thefilter body 17, thecapsule member 23 embedded in thefilter body 17 and containing a flavorant, and the adhesive 24 that bonds thefilter body 17 and thecapsule member 23. - Generally, the fibers constituting the
filter portion 15 extend in the axial direction (the direction of the central axis C) of thefilter portion 15. Therefore, when an external force is applied to a capsule member, in some rare cases, the capsule member may move to be displaced along the direction in which the fibers extend. However, since such an event occurs very rarely, it was almost impossible for the manufacturer to recognize the event as a problem. According to the above configuration, by fixing thecapsule member 23 to thefilter body 17 with the adhesive 24, thecapsule member 23 can be prevented from being out of position within thefilter portion 15. As a result, it is possible to prevent a situation in which thecapsule member 23 moves to be displaced and cannot be easily crushed, thereby improving the convenience of the user. - The adhesive 24 is a thermoplastic resin. According to this configuration, since the resin is completely solidified when the product is shipped, it is possible to prevent the
capsule member 23 from moving in thefilter portion 15, thereby realizing a smoking article in which thecapsule member 23 can be easily crushed. Further, since moisture does not come out from the adhesive 24 at the time of solidification, thecapsule member 23 can be prevented from being weakened by water. - The capsule shell of the
capsule member 23 is formed of a hydrophilic material which is weakened by water absorption. In particular, the capsule shell of thecapsule 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 the above configurations, 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 paste, thecapsule member 23 is not weakened and is prevented from becoming difficult to crush. - The
capsule member 23 is positioned on or near the central axis C of thefilter portion 15, and the adhesive 24 linearly extends along the central axis C on or near the central axis C of thefilter portion 15. According to this configuration, even when the position of thecapsule member 23 is out of position with respect to the direction of the central axis C due to manufacturing variations, since the adhesive 24 extends linearly along the central axis C, a slight displacement of thecapsule member 23 can be allowed, and thecapsule member 23 can be reliably fixed to thefilter portion 15. - The
capsule member 23 is positioned on or near the central axis C of thefilter portion 15, and a part of the adhesive 24 is positioned in a projected section in the direction of the central axis C of thecapsule member 23. According to this configuration, the adhesive 24 can be disposed at a position overlapping thecapsule member 23. As a result, the adhesive 24 is not applied to a position away from thecapsule member 23. Thus, it is possible to prevent such a problem wherein the adhesion between thecapsule member 23 and thefilter portion 15 is not successful. - The adhesive 24 includes a flavorant. According to this configuration, since the flavorant can be contained in the adhesive 24, it is not necessary to separately provide cotton yarn or the like containing the flavorant 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. Furthermore, the manufacturing process can be simplified and the manufacturing cost can be reduced as compared with the case of separately providing cotton yarn or the like containing the flavorant. - The adhesive 24 includes a pigment. According to this configuration, the adhesive 24 can be colored, and the portion where the adhesive 24 is solidified can be decorated. Generally, the color of the portion coated with the adhesive 24 in the
filter portion 15 is not substantially different from the color of the portion not coated with the adhesive 24 in thefilter portion 15. The portion of thefilter portion 15 to which the adhesive 24 is applied is merely harder than the other portions. According to the above configuration, it is possible to positively contribute to the improvement of the appearance at the place where the adhesive 24 is applied, so that the freedom of the smoking article design can be improved. - The
capsule member 23 is positioned at a distance shorter than 15 mm or 10 mm from themouthpiece end 26 of thefilter portion 15 in the direction of the center axis C toward theaerosol generating rod 14. According to this configuration, it is possible to place thecapsule member 23 near themouthpiece end 26, and the flavorant can be put on the mainstream smoke at a position close to the mouth of the user. Thus, thecapsule member 23 can be arranged at a position where the flavorant can be delivered to the user's oral cavity most efficiently. Further, in the present embodiment, thecapsule member 23 and thefilter portion 15 are bonded by the adhesive 24. Therefore, even in the arrangement mentioned above, it is possible to prevent thecapsule member 23 from falling off thefilter portion 15. - Next, a smoking article (cigarette) according to a first modification of the embodiment will be described. The first modification is different from the above embodiment in that the material of the
capsule shell 22 of thecapsule member 23 and the type of the adhesive 24 are different, but other parts are the same. In the following, the parts different from those of the above-described embodiment will be mainly described, and descriptions of the parts that are the same as those of the above-described embodiment will be omitted. - The capsule member 23 (capsule shell 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 other kinds of resin materials (synthetic resin materials), such as polypropylene, polyurethane, polyvinyl chloride, and the like. The melting point of thecapsule member 23 formed of polypropylene, for example, 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, when the thermoplastic resin (hot-melt adhesive) is used as the adhesive 24, there is a possibility that a hole may be formed in thecapsule member 23 when the thermoplastic resin is melted. - Unlike the embodiment, the adhesive 24 of this modification is composed of an aqueous dispersion adhesive. The aqueous dispersion adhesive exhibits an adhesive performance by evaporation of the water at normal temperature (room temperature). In the embodiment, for example, a vinyl acetate resin emulsion adhesive among the aqueous dispersion adhesives can be suitably used as the adhesive 24.
- The arrangement of the adhesive 24 is the same as that of the embodiment described above. Also, as well as the embodiment described above, a flavorant may be mixed with the adhesive 24, and the pigment may be mixed with the adhesive 24. According to this modification, since the
capsule member 23 is formed of a resin material, the strength of thecapsule member 23 is improved, and a problem wherein thecapsule member 23 is unexpectedly crushed or the like during transportation is prevented. - According to this modification, the adhesive 24 is an aqueous dispersion adhesive. With this configuration, an inexpensive and safe adhesive can be used as the adhesive 24. Thus, since the adhesive 24 is a liquid from the beginning, it is not necessary to apply heat to melt the adhesive 24. Therefore, it is possible to prevent holes from being formed in the
capsule member 23, which may be formed if thecapsule member 23 is formed of a resin material or the like by heating the adhesive 24 formed of a thermoplastic resin (hot-melt adhesive) to melt the adhesive and applying the adhesive to thefilter portion 15 and thecapsule member 23. - The
capsule shell 22 of thecapsule member 23 is formed of a resin material. According to this configuration, when the aqueous dispersion adhesive is used as the adhesive 24, thecapsule member 23 does not absorb the moisture that is diffused (volatilized) from the aqueous dispersion adhesive, and it is possible to prevent the situation wherein thecapsule member 23 is difficult to crush due to the moisture. - Next, referring to
FIG. 4 , a smoking article (cigarette) according to a second modification of the embodiment will be described. Thecigarette 11 according to the second modification is different from the above-described embodiment in that asecond filter portion 31 is provided in addition to thefilter portion 15, but the other parts are the same as those of the above-described embodiments. In the following, the parts different from those of the above-described embodiment will be mainly described, and descriptions of the parts that are the same as those of the above-described embodiment will be omitted. - As shown in
FIG. 4 , thecigarette 11 includes theaerosol generating rod 14 including cut tobacco 12 (shredded leaves, tobacco) and thecigarette paper 13 wrapped around thecut tobacco 12, thefilter portion 15 disposed coaxially with theaerosol generating rod 14, thesecond filter portion 31 disposed coaxially with theaerosol generating rod 14 at a position between theaerosol generating rod 14 and thefilter portion 15, and the tippingpaper member 16 wrapped around theaerosol generating rod 14 and thefilter portion 15 so as to connect theaerosol generating rod 14, thesecond filter portion 31, and thefilter portion 15. - The configuration of the
filter portion 15 is the same as that in the above-described embodiment, except that the length in the central axis C is about half of the length of the first embodiment. Thefilter portion 15 is provided with thecapsule member 23 in the same manner as in the above-described embodiment. - The
second filter portion 31 is formed in the same manner as thefilter portion 15 of this modification. Thesecond filter portion 31 differs from thefilter portion 15 in that it does not have thecapsule member 23, but the other parts are the same as those of thefilter portion 15. In the present modification, thesecond filter section 31 is composed of one piece, but it may be composed of two or more pieces. - According to this modification, at least one
second filter section 31 is provided between theaerosol generating rod 14 and thefilter portion 15. With this configuration, even in thecigarette 11 using a multi-segment filter, the movement of thecapsule member 23 with respect to thefilter portion 15 can be prevented, and thecigarette 11 in which thecapsule member 23 can be easily crushed can be realized. - Next, referring to
FIG. 5 , a smoking article (cigarette) according to a third modification of the embodiment will be described. The third modification is different from the above embodiment in that thecapsule member 23 is provided at a different position, but the other parts are the same as those of the above embodiment. In the following, the parts different from those of the above-described embodiment will be mainly described, and descriptions of the parts that are the same as those of the above-described embodiment will be omitted. - The configuration of the
filter portion 15 is the same as that of the embodiment except that thecapsule member 23 is provided at a different position. In this modification, thecapsule member 23 is disposed at a distance of 20 mm or shorter from themouthpiece end 26 in the direction of the central axis C. In other words, thecapsule member 23 is provided at a middle portion in the central axis C direction (longitudinal direction) of thefilter portion 15. - Even in the case where the
capsule member 23 is provided in the middle portion in the longitudinal direction of thefilter portion 15 as in the present modification, the movement of thecapsule member 23 with respect to thefilter portion 15 can be prevented by the adhesive 24, and the user's convenience can be improved. - Next, referring to
FIG. 6 , a smoking article according to a fourth modification of the embodiment will be described. In the fourth modification, asmoking article 41 is not a cigarette, but belongs to the field of so-called electronic cigarettes in which anaerosol generating rod 14 is heated by a so-called electric heater or the like. In the following, the parts different from those of the above-described embodiment will be mainly described, and descriptions of the parts that are the same as those of the above-described embodiment will be omitted.FIG. 6 is a sectional view cut along a plane including the central axis C, showing a lower half of arod member 46 of thesmoking article 41 and amain body 45. - The
smoking article 41 includes themain body 45 including abattery 42, anelectric heating portion 43, and arecess 44, and therod member 46 detachably inserted into therecess 44 of themain body 45. Therecess 44 is formed in a part of acase 45A of themain body 45. Thebattery 42 can be charged and discharged. Theelectric heating portion 43 is a so-called heater, and has a heat generating element disposed to surround therecess 44. The heat generating element of theelectric heating portion 43 heats theaerosol generating rod 14 and causes afiller 61 of theaerosol generating rod 14 to release a fragrance into the surrounding air. The heating temperature of theaerosol generating rod 14 by theelectric heating portion 43 is, for example, 400° C. or lower, which is considerably lower than the combustion temperature of the cigarette of the conventional ignition type at 700 to 800° C. By heating at such a low temperature, the amount of mainstream smoke generated from theaerosol generating rod 14 is reduced as compared with thecigarette 11 of the embodiment. Therefore, the filtering function of thefilter portion 15 of the present modification is preferably lower than that of thefilter portion 15 of thecigarette 11 of the embodiment, so that a preferred amount of mainstream smoke is shared in the mouth of the smoker. In this modification, in order to reduce the mainstream smoke filtration of thefilter portion 15, the length of thefilter portion 15 in the direction of the central axis C is shorter than that in the above-described embodiment. It is also possible to shorten the length in which the filter body is disposed out of the total length of the filter portion, and to dispose a tube portion or other segment having a low filtration rate of the mainstream smoke in the remaining portion. - The
rod member 46 has a cigarette shape. Therod member 46 includes a tubularcylindrical portion 51, theaerosol generating rod 14 provided at oneend portion 51A of thecylindrical portion 51, thefilter portion 15 provided at theother end portion 51B opposite to the oneend portion 51A of thecylindrical portion 51, asecond filter portion 31 disposed coaxially with theaerosol generating rod 14 at a position between theaerosol generating rod 14 and thefilter portion 15, and atipping paper member 16 connecting thecylindrical portion 51, theaerosol generating rod 14, and thefilter portion 15. - The
cylindrical portion 51 is formed of, for example, a thick paper having a thickness of 100 to 300 μm in a cylindrical shape so as to have a predetermined rigidity. The tippingpaper member 16 is supported by the rigidcylindrical portion 51, and even when therod member 46 is pressed in the direction of the central axis C, the tippingpaper member 16 is not crushed in the direction of the central axis C. The tippingpaper member 16 and thecylindrical portion 51 have a plurality ofvents 53 on a part of the outer circumference. The plurality ofvents 53 extend through the tippingpaper member 16 and thecylindrical portion 51. The number ofvents 53 is, for example, 10 to 40. Thevents 53 are arranged, for example, in a row in an annular shape on the outer circumference of the cylindrical portion. Thevents 53 are formed at regular intervals. - The
aerosol generating rod 14 includes thefiller 61 including cut tobacco 12 (shredded leaves, tobacco), tobacco sheet shreds, folded or circumferentially rolled tobacco sheets, pleated tobacco sheets, or non-tobacco filler and the like, and acigarette paper 54 wrapped around thefiller 61. Thecigarette paper 54 may be paper alone, or may be formed of paper bonded with a metal foil having a good thermal conductivity, such as an aluminum foil or a stainless steel foil. - The configuration of the
filter portion 15 is substantially the same as that of the other embodiments except that the length of thefilter body 17 in the direction of the central axis C is shorter. Thefilter portion 15 includes thefilter body 17 having a cylindrical shape, afilter wrapping paper 21 wrapped around thefilter body 17, acapsule member 23 that is embedded within the filter portion 15 (within the filter body 17) and that encapsulates a content liquid containing a flavorant inside acapsule shell 22, and an adhesive 24 that bonds thefilter body 17 and thecapsule member 23. Thecapsule member 23 is positioned at a distance shorter than 10 mm from amouthpiece end 26 of thefilter portion 15 in the direction of the central axis C toward theaerosol generating rod 14. More preferably, thecapsule member 23 is positioned at a distance shorter than 6 mm from themouthpiece end 26 of thefilter portion 15 in the direction of the central axis C toward theaerosol generating rod 14. - The
second filter portion 31 differs from thefilter portion 15 in that it does not have thecapsule member 23, but the other parts are the same as those of thefilter portion 15. In the present modification, thesecond filter section 31 is composed of one piece, but it may be composed of two or more pieces. Thefilter portion 15 and thesecond filter portion 31 are connected by a secondfilter wrapping paper 62. - According to the present modification, the same effects as those in the above-described embodiment are obtained. That is, the user can enjoy the flavor and taste of the smoking article in the oral cavity by inhaling through the
filter portion 15 and thecylindrical portion 51, while therod member 46 is attached to themain body 45. - According to this modification, the
smoking article 41 includes theelectric heating portion 43 for heating theaerosol generating rod 14. With this configuration, in thesmoking article 41 that belongs to the field of so-called electronic cigarettes, the ease of crushing thecapsule member 23 can be similarly improved, and the convenience of the user can be improved. In particular, in the case of using theelectric heating portion 43, the length of thefilter body 17 of thefilter portion 15 tends to be short because the amount of the mainstream smoke is small. According to this modification, the movement of thecapsule member 23 can be prevented even in theshort filter body 17. As described above, the movement of the capsule member can be effectively prevented in thesmoking article 41 having theshort filter body 17, in which the possibility of thecapsule member 23 falling off from thefilter body 17 is high. This is extremely useful in the design of the product. - The smoking article is not limited to the above embodiment and modifications and can be embodied by modifying structural elements in the implementation stage without departing from the gist thereof. Therefore, the smoking article described above is obviously applicable to smoking articles by which the user enjoys the fragrance of tobacco without heating. Further, some of the components may be deleted from all the components shown in the embodiments, or different modifications may be appropriately combined to constitute one invention.
- Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described herein. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalents.
