Description

 Smoking article with filter  

The present invention relates to a smoking article with a filter attached thereto.

A smoking article with a filter, such as a cigarette with a filter, is abutting the tobacco rod with the filter, and the outer peripheral surface of the downstream end of the tobacco rod and the outer peripheral surface of the filter are wound by the filter paper. Its integration. Filter paper typically has a seam that hides the filter from the tobacco rod and hides the masking function of the color of the tar attached to the filter by smoking, thus using opaque paper.

In recent years, a configuration in which a fragrance capsule is disposed inside a filter to which a smoking article of a filter is attached has been known. In the smoking article with a filter, the smoker ruptures the fragrance capsule at the time of use, so that the flavor of the content liquid of the fragrance capsule can be enjoyed, and the odor of the cigarette butt can be eliminated (Patent Document 1). However, in the filter-attached smoking article in which the fragrance capsule is disposed inside the filter, if an opaque filter paper is used, it is not easy for the smoker to visually confirm whether the content liquid of the fragrance capsule has been sufficiently released after the fragrance capsule is broken. To the problem inside the filter. Therefore, in order to visually confirm that the content liquid of the fragrance capsule has been sufficiently released into the filter, a smoking article with a filter is studied, so that the content liquid of the fragrance capsule contains a dye, and is disposed on a part of the opaque filter paper. A window that visualizes the filter.

However, in such a smoking article with a filter, generally, after the fragrance capsule is broken, even if the content liquid is sufficiently released into the filter, the released content liquid will only permeate to the peripheral portion of the filter. position. Specifically, as shown in Fig. 1(a), when the outer peripheral surface of the filter FL in which the fragrance capsule CP is disposed is sandwiched by the index finger F1 and the thumb F2, and the force P is pressed to rupture the fragrance capsule CP, As shown in Fig. 1(b), most of the content liquid only partially penetrates into a part (region S) of the outer peripheral surface of the squeezed filter FL. Therefore, even if a window is provided in a part of the filter paper, if the position of the peripheral surface (area S) of the filter which is partially saturated with the liquid of the content liquid does not match, the smoker cannot visually confirm the content liquid of the fragrance capsule. Fully released situation.

In order to solve the above problems, the present invention provides a smoking article with a filter. In a smoking article with a filter in which a fragrance capsule is disposed inside a filter, the smoker can visually confirm the fragrance capsule after the fragrance capsule is broken. The colored content liquid has been fully released.

(First embodiment)

Fig. 2 is a schematic perspective view of the smoking article 1 with a filter according to the first embodiment. Fig. 3 is a schematic cross-sectional view showing a cross section taken along line III-III of Fig. 2 in an enlarged manner. Fig. 4(a) is a schematic cross-sectional view showing a cross section taken along line IV-IV of Fig. 3, and Fig. 4(b) is a view schematically showing an arrangement of a transparent portion of Fig. 4(a). The smoking article 1 with a filter is provided with a smoking main body 11, a filter 12, and a filter paper 13.

The smoking main body 11 such as the tobacco rod 11 is composed of the shredded tobacco 111 and the cigarette paper 112 wound around the shredded tobacco 111 in the same manner as a general cigarette. The cigarette paper 112 is, for example, paper having air permeability.

The filter 12 is disposed at the downstream end of the tobacco rod 11. The filter 12 has the same or substantially the same diameter as the tobacco rod 11. The filter 12 includes a filter member 121 having a single structure, a filter take-up piece 122 wound along the outer peripheral surface of the filter member 121, and a fragrance capsule 15 disposed inside the filter member 121. That is, the filter 12 is provided with a single filter member 121 and has a so-called single filter structure.

The filter member 121 is made of, for example, cellulose acetate.

The filter take-up sheet 122 is a breathable paper that is disposed to face the region where the fragrance capsule 15 is broken and the colored content liquid is released. The breathable paper is paper having a gas permeability of from 1000 C.U. to 30,000 C.U. The breathable paper preferably has a gas permeability of from 1000 C.U. to 24,000 C.U., more preferably from 1000 C.U. to 10,000 C.U. Further, the air permeability referred to in the present specification is a value measured in accordance with ISO 2965:2009, and shows a flow rate (cm ³ ) of a gas having an area of 1 cm ² per minute when the differential pressure on both surfaces of the paper is 1 kPa. The so-called 1C.U. (1coresta unit) is cm ³ /(min‧cm ² ) at 1 kPa.

The opacity of the air permeable paper is preferably 30% or more, preferably 40% or more and 70% or less, more preferably 50% or more and 60% or less. When the colored content liquid 152 of the fragrance capsule 15 is impregnated with such a permeable paper having an opacity of 30% or more, a vivid color appears. Further, in the present specification, the opacity is measured by whiteness ‧ opacity measuring instrument (manufacturer: Murakami Color Technology Research Institute, model: WMS-1), and the values of whiteness and opacity are measured according to ISO 2470 and ISO 2471, respectively. The opacity is a value calculated from a single sheet visual reflectance coefficient (R0)/inherent visual reflectance coefficient (R∞) × 100 (%). The intrinsic visual reflectance coefficient (R∞) of this formula is an intrinsic reflectance coefficient of whiteness measured under a spectroscopic condition of an effective wavelength of 457 nm and a half width of 44 nm using a predetermined reflectance meter and a light source. .

The air-permeable paper is not particularly limited as long as it has the above physical properties. For example, NIPPON PAPER PAPYLIA CO., LTD. paper: LPWS-OLL (basis weight: 26.5 gsm, air permeability: 1300 C.U., Thickness: 48μm), NIPPON PAPER PAPYLIA CO., LTD. Paper: S52-7000 (basis weight: 52gsm, air permeability 7000C.U., thickness: 110μm), NIPPON PAPER PAPYLIA CO., LTD. Non-woven fabric: P-10000C (basis weight: 24gsm, air permeability: 10000C.U., thickness: 60μm), P-20000C (basis weight: 26.5gsm, air permeability: 20000C.U., thickness: 75μm), P- 30000C (basis weight: 21gsm, air permeability: 30000C.U., thickness: 77μm), PW/TCF/12000-27.50×4500m (basis weight: 25gsm, air permeability: 24000C.U., thickness: 71μm), and PPW 240E2 26, 50/4500 (basis weight: 21.5 gsm, air permeability: 24000 C.U., thickness: 70 μm).

The fragrance capsule 15 is disposed inside the filter 12, for example, buried in the center of a cross section perpendicular to the longitudinal direction of the filter member 121. The fragrance capsule 15 includes a capsule body 151 and a colored content liquid 152 containing a fragrance component held in the capsule body 151. Here, the term "colored" means any color, but bright colors of red, orange, yellow, blue, and green are preferred. The fragrance capsule 15 is a crack-type fragrance capsule which can release the colored content liquid 152 therein by being ruptured by the force from the outside. As the material of the capsule body 151, for example, starch, dextran, polysaccharides, cold weather, tarnish, gelatin, various resin materials (polyvinyl chloride, polyvinylidene chloride, polystyrene, styrene) can be used. - Acrylonitrile copolymer, styrene-butadiene-acrylonitrile copolymer, polyethylene, polypropylene, cellulose acetate, polyethylene terephthalate, polyamide, ethylene-acrylic plastic, ethylene-vinyl acetate Ester plastic, ethylene-vinyl alcohol plastic), various natural gelling agents, etc. The capsule body 151 may contain a fragrance component, a plasticizer, a dye, or the like in addition to the above materials. The shape of the fragrance capsule 15 is not particularly limited, and may be a spherical shape, a cylindrical shape, or a truncated cone shape. The fragrance capsule may be, for example, a spherical shape having a diameter of 2 mm to 5 mm or a cylindrical shape having a diameter of 5 mm to 7 mm and a length of 5 mm to 10 mm.

As the flavor component, for example, menthol, plant essential oil or the like can be used. One form of the colored content liquid 152 contains a dye in addition to the fragrance component. For the dye in the colored content liquid 152, for example, various synthetic dyes and natural dyes can be used. The specific dye is preferably a food additive such as red 3,106, beta carotene (orange), copper chlorophyll sodium (green), gardenia blue, yellow 4 or the like. The colored content liquid 152 may further contain a solvent for dissolving the fragrance component and the dye. As the solvent, three medium chain fatty acid glycerides (MCT) (for example, caprylic acid, tricaprylin), glycerin, propylene glycol, water, ethanol, or the like can be used. The colored content liquid 152 may further contain other additives such as an emulsifier and a tackifier. In addition, colored plant essential oils can be used as the perfume ingredient. Further, a colored solvent can be used as the solvent. In these forms, the colored content liquid 152 may not necessarily contain a dye.

Further, when the fragrance capsule 15 is broken, the colored content liquid 152 is released and permeated to the filter member 121 and the filter take-up sheet 122 belonging to the breathable paper. Therefore, the colored content liquid 152 is preferably adjusted to have a viscosity of 120 mPa·s or less, preferably 90 mPa·s or less, to improve the permeability to the filter member or the like.

Further, in consideration of the release of the colored content liquid 152 after the fragrance capsule 15 is broken, the colored content liquid can be sufficiently permeated to the gas permeable paper via the filter member 121, and the amount of the colored content liquid/the sectional area of the filter is 0.2 μl/mm. ² or more is preferable, preferably 0.3 μl/mm ² or more and 0.7 μl/mm ² or less. If the amount of the colored content liquid/the cross-sectional area of the filter is less than 0.2 μl/mm ² , the colored liquid 152 of the fragrance capsule 15 may be insufficient to penetrate the filter roll of the permeable paper with respect to the volume of the filter. The possibility of taking the sheet 122 is therefore not ideal. On the other hand, if the amount of the colored content liquid/the cross-sectional area of the filter is 2.2 μl/mm ² or more, the amount of the colored content liquid 152 of the fragrance capsule 15 is excessive with respect to the volume of the filter, and there may be a colored content. The possibility that the liquid reaches the downstream end of the filter and adheres to the lips of the smoker is therefore not ideal. Further, the amount of the colored content liquid 152 of the fragrance capsule 15 is, for example, 3 μl to 100 μl. Further, the cross-sectional area of the filter 12 is, for example, 20 mm ² to 50 mm ² .

The method for producing the fragrance capsule 15 is not particularly limited, but for example, a dropping method is preferably used. The drop-off method produces a perfume capsule 15 having a seamless seamless capsule body 151. In the dropping method, the two-layer supply nozzle is used, and the colored content liquid 152 and the liquid film substance are simultaneously discharged from the inner supply nozzle and the outer supply nozzle, and the colored content liquid 152 can be packaged in the capsule body 151 without the seam. In. Further, the fragrance capsule 15 may be formed by encapsulating the content liquid (excluding the dye) by the capsule body containing the dye, and when stored, the dye of the capsule body is dissolved and transferred to the content liquid to become a colored content liquid.

The filter paper 13 is wound around the outer peripheral surface of the downstream end portion of the tobacco rod 11 and the outer peripheral surface of the filter 12, and the tobacco rod 11 is connected to the filter 12. The filter paper 13 has a transparent portion 13a and an opaque portion 13b. As shown in Fig. 4(a), the transparent portions 13a of the filter paper 13 are disposed at least three apart from each other along the circumferential direction of the filter paper 13. Each of the transparent portions 13a is disposed to face a region where the colored content liquid is released. The transparent portion 13a of the filter paper 13 is preferably disposed at a portion in the circumferential direction of a cross section perpendicular to the longitudinal direction of the filter 12. In particular, as shown in Fig. 4(b), when viewed from the center point R of the cross section perpendicular to the longitudinal direction of the filter 12, the respective transparent portions 13a of the filter paper 13 are arranged in the adjacent transparent portion 13a. The angular interval θ is preferably 150° or less. In this manner, the transparent portions 13a are arranged at an angular interval of 150° or less, and the arrangement balance of the plurality of transparent portions 13a is improved. The angular interval θ is preferably 140° or less, more preferably 130° or less, and most preferably 120° or less. The transparent portion 13a of the filter paper 13 is disposed three to eight, preferably three to five, along the circumferential direction of the filter paper 13.

In the relationship between the number of the transparent portions 13a of the filter paper 13 and the arrangement of the angular intervals θ, for example, the transparent portions 13a are arranged three along the circumferential direction of the filter paper 13, and the adjacent first ones are When the angular interval θ1 of the second transparent portion 13a is 150 ° C, the angular intervals θ2 and θ3 of the third transparent portion 13a adjacent to the first transparent portion 13a and the second transparent portion 13a add up to 210. ° (360° to 150°), the total angular interval 210° can be arbitrarily distributed in an angular interval θ2 with respect to the first transparent portion 13a and an angular interval θ3 with respect to the second transparent portion 13a in a range of 150° or less. And configuration. That is, the third transparent portion 13a is along the circumferential direction of the filter paper 13, at an angular interval θ2 of 60° to 150° with respect to the first transparent portion 13a, and at 60° with respect to the second transparent portion 13a. The range of the angular interval θ3 of 150° is respectively arranged. By the arrangement of the three transparent portions 13a, when the fragrance capsule 15 is broken, it can be quickly visually transmitted through at least one of the three transparent portions 13a regardless of the pressure at any position on the circumference of the filter 12. Confirm the color of the breathable paper. In particular, it is preferable that the three transparent portions 13a are arranged along the circumferential direction of the filter paper 13 at equal angular intervals, that is, at an angular interval of 120°. Further, in the case where four or five transparent portions are arranged along the circumferential direction of the filter paper, the angular intervals of the adjacent transparent portions 13a are equally angularly spaced, that is, at an angular interval of 90° and 72°. .

In the configuration in which the transparent portion 13a of the filter paper 13 is disposed to face the region where the colored content liquid is released, in the configuration of the filter-attached smoking article 1 shown in FIGS. 2 to 4, The arrangement of the portion including the transparent portion 13a and the fragrance capsule 15 is preferable. At this time, when the fragrance capsule 15 is broken and the colored content liquid 152 is released, the dyed portion can be easily visually recognized through the transparent portion 13a.

As shown in Fig. 2, the transparent portion 13a of the filter paper 13 preferably has a shape having a length W along the longitudinal direction of the filter 12 longer than a length L along the circumferential direction of the filter paper 13 . At this time, even if the arrangement position of the fragrance capsule 15 is shifted from the longitudinal direction of the filter 12, and the fragrance capsule 15 is broken to release the colored content liquid 152, the dyed portion can be easily visually recognized through the transparent portion 13a. The length L of the transparent portion 13a is 1 mm to 4 mm, and the length W is preferably 2 mm to 8 mm. For example, the transparent portion 13a has a rectangular shape having a length L of 3 mm and a length W of 5 mm. When the area of the transparent portion 13a is too large, the area of the air permeable paper that can be visually recognized from the outside becomes large, and the colored content liquid of the fragrance capsule 15 cannot completely penetrate into the visually identifiable area, so that it is aesthetically pleasing. not ideal. Although an example of the rectangular transparent portion 13a is shown in Fig. 2, the shape of the transparent portion 13a is not limited thereto, and may be, for example, a character, a geometric shape, a trademark, or the like. Further, the lengths L and W of the case of the geometric shape or the like are close to the lengths L and W of the circumscribed pattern.

For the filter paper 13, for example, a sheet-like substrate which is transparent as a whole can be used, and an opaque ink can be printed on a region other than the transparent portion 13a by, for example, gravure printing or inkjet printing. The opaque ink can be printed on both sides of the sheet substrate or printed on either side. Further, if opaque ink is printed on only one side of the sheet-like base material of the filter paper 13, it is preferable to prevent the opaque ink from adhering to the lips of the smoker when smoking, resulting in an uncomfortable feeling. Further, when the opaque ink is printed on the inner side of the sheet-like base material of the filter paper 13, the smoker visually confirms the opaque portion 13b through the sheet-like base material. Therefore, a different visual appearance can be created than when the opaque ink is printed on the outer side of the sheet-like substrate of the filter paper 13. The color of the opaque portion 13b is not particularly limited, and may be, for example, the same color as the filter member 121. Further, the filter paper 13 is not limited to the above-described configuration. For example, the transparent portion 13a may be formed by cutting a part of a sheet constituting the opaque portion 13b and attaching a transparent sheet to a part thereof.

The filter paper 13 is impermeable to the colored content liquid 152 of the fragrance capsule 15. The filter paper 13 includes, for example, a sheet-like base material which is transparent as a whole and which is impermeable to the colored content liquid 152 of the fragrance capsule 15 . The sheet substrate is, for example, a polyolefin film such as cellophane or polypropylene film, a polyvinyl chloride film, or a cellulose acetate film. The sheet substrate may also be formed by coating a resin such as nitrocellulose, ethyl cellulose, polyvinyl alcohol or polyvinyl acetate on the outer side surface, the inner side surface or both sides to form a liquid non-permeable layer, or The liquid non-permeable layer is formed using a substance having low affinity with the colored content liquid 152. For example, in the case where medium chain fatty acid (MCT) is used as a main component of a solvent of the colored content liquid 152, the material of the liquid non-permeable layer may be starch, modified starch, pectin, sodium alginate, eucalyptus, and tamarind seed. Polysaccharides having hydrophilic properties such as pectin and carrageenan. Since the filter paper 13 is impermeable to the colored content liquid 152, the colored content liquid 152 can be prevented from permeating to the outer side of the filter paper 13, and the colored content liquid 152 can be prevented from adhering to the smoker's lips or hands. By forming the liquid-impermeable layer, it is also possible to prevent the sheet-like substrate from absorbing moisture and swelling when the colored content liquid penetrates into the sheet-like substrate, thereby affecting the quality of the cigarette.

The sheet-like base material of the filter paper 13 is, for example, P-BD #600 (trade name) manufactured by Futamura Chemical Co., Ltd., P-BD #500 (trade name), P-BD #300. A cellophane (trade name), a cellulose acetate film of Clarifoil (registered trademark) manufactured by Celanese Corporation, a polyolefin film of TAF (Japanese registered trademark) manufactured by Mitsui Chemicals Tohcello, Inc., and biaxially oriented polycondensation of HC-OP Acrylic film, etc.

The filter paper 13 is a common adhesive used in the manufacture of a general smoking article with a filter to follow the tobacco rod 11 and the filter 12. The type of the adhesive used to connect the filter paper 13 to the tobacco rod 11 and the filter 12 is not particularly limited, and a vinyl acetate-based adhesive, a starch, a modified starch-based adhesive, or the like can be used, or a use can be used. It actually turns into a transparent adhesive after drying. Further, as long as the purpose of adhering the filter paper 13 to the tobacco rod 11 and the filter 12 can be achieved, the region in which the adhesive is applied can be spread over the entire adhesive surface, or a region in which the adhesive is not applied partially.

Further, when the filter paper 13 is wound around the downstream end portion of the tobacco rod 11 and the outer peripheral surface of the filter 12, the filter paper 13 is not easily broken and can be fitted with the shape of the smoking article with the filter attached thereto. The package, the filter paper 13 preferably has a basis weight of from 20 gsm to 100 gsm, preferably from 25 gsm to 50 gsm. For the same reason, the filter paper 13 preferably has a thickness of 15 μm to 80 μm, preferably 18 μm to 40 μm.

Here, the action of the filter-attached smoking article 1 of the first embodiment will be described.

When the smoking article 1 with the filter is sucked, the mainstream smoke from the tobacco rod 11 is discharged from the downstream end of the filter 12 through the filter 12. The smoker grips and squeezes the filter 12, for example, with the index finger and the thumb, rupturing the capsule body 15 inside the filter 12 to collapse the fragrance capsule 15, and releasing the colored content liquid 152 from the fragrance capsule 15 to the filter member 121. . Thereby, the fragrance of the flavor component added to the mainstream smoke from the tobacco rod 11 can be enjoyed. When the colored content liquid 152 of the fragrance capsule 15 is released to the filter member 121, the colored content liquid 152 reaches the filter take-up sheet 122 composed of the air permeable paper disposed opposite to the release area. At this time, the filter take-up sheet 122 composed of the air permeable paper has a predetermined air permeability of 1000 C.U. to 300,000 C.U. Therefore, the high-impregnation effect of the capillary phenomenon allows the colored content liquid to rapidly permeate and diffuse to The vast area of breathable paper. Further, in the case of using the filter take-up sheet 122 composed of air permeable paper having a predetermined opacity of 30% or more, when the colored content liquid 152 is saturated, the filter take-up sheet 122 may exhibit vivid colors. Can improve visual confirmation. As a result, the smoker can easily visually confirm the filter take-up sheet 122 of the breathable paper which rapidly develops a vivid color from the transparent portion 13a of the filter paper 13 from the outside, and can quickly confirm the breakage of the fragrance capsule 15.

Further, the filter paper 13 wound around the outer peripheral surface of the filter member 121 is provided with at least three transparent portions 13a which are disposed apart from each other along the circumferential direction thereof, from the center point of the cross section perpendicular to the longitudinal direction of the filter 12. In the observation, when the transparent portions 13a are arranged such that the angular interval between the adjacent transparent portions 13a is 150 or less, when the fragrance capsule 15 is broken, it can be transmitted regardless of any position from the circumferential direction of the filter 12. At least one of the three transparent portions 13a visually confirms the dyed state of the colored content liquid 152 in the filter take-up sheet 122 of the breathable paper. As a result, the smoker can visually confirm the state in which the fragrance capsule 15 is broken with a higher probability.

Therefore, according to the first embodiment, it is possible to provide a smoking article with a filter, which can visually confirm the breakage of the fragrance capsule 15, and the colored content liquid 152 accompanying the breakage of the fragrance capsule is sufficiently released into the inside of the filter 12, and can also enjoy the fragrance. The flavor component within the capsule 15.

The air permeable paper may be present on the outer side of the filter member as long as it is wound, and other layers may be present between the filter member and the permeable paper in a range that does not prevent the function of rapidly penetrating and diffusing the colored content liquid. In addition, the filter paper may be wound along the outer peripheral surface of the filter, and the other layer may be present in the permeable paper and the range in which the colored liquid is allowed to permeate through the transparent portion and diffuse into the permeable paper. Between the filter papers.

Further, in the first embodiment, an example in which a single fragrance capsule is disposed inside the filter has been described, but the invention is not limited thereto. A plurality of perfume capsules can also be placed inside the filter. At this time, among the values of the amount of the colored content liquid/the cross-sectional area of the filter, the amount of the colored content liquid indicates the total amount of the colored content liquid of the plurality of fragrance capsules.

In addition, cigarette-like smoking articles and such specifications are generally referred to as cigarettes in the following manner depending on the length of the cigarette. "Standard length" is generally in the range of 68 mm to 75 mm, for example, a length of about 68 mm to about 72 mm; "short" or "mini" is a length of 68 mm or less, and "oversize" is generally in the range of 75 mm to 91 mm, for example, about 79 mm. To a length of about 88 mm; "long" or "oversized" is generally in the range of 91 mm to 105 mm, such as a length of about 94 mm to 101 mm; "ultra-long" is generally a length in the range of about 110 mm to about 121 mm. Moreover, the smoking articles may also be given a cigarette name in the following manner according to the periphery of the cigarette. "Standard outer circumference" is an outer circumference of about 23 mm to 25 mm, "thickness" is an outer circumference of 25 mm or more, "thin" is an outer circumference of about 22 mm to 23 mm, "fine" is an outer circumference of about 19 mm to 22 mm, and "superfine" is about The outer circumference of 16 mm to 19 mm, and "very fine" is an outer circumference of less than 16 mm. Therefore, an oversized and ultra-fine cigarette is, for example, having a length of about 83 mm and an outer circumference of about 17 mm. Standard peripheral, oversized cigarettes, that is, cigarettes having a length of 75 mm to 91 mm and outer circumferences of 23 mm to 25 mm, are favored by most customers. Smoking articles of various sizes can also be manufactured with filters of different lengths. In general, short filters are used for smoking articles of a shorter length and a shorter circumference. In general, the length of the filter is 15mm for smoking articles of the "short" and "standard" specifications, and 30mm for smoking articles of the "extra long" and "ultra-fine" specifications. The length of the filter paper in the longitudinal direction of the smoking article with the filter is, for example, 3 mm to 10 mm longer than the length of the filter.

(Second embodiment)

Fig. 5 is a schematic perspective view of a smoking article 2 with a filter according to a second embodiment. Fig. 6 is a schematic cross-sectional view showing a cross section taken along line VI-VI of Fig. 5 in an enlarged manner. In the filter-attached smoking article 2 of the second embodiment, the filter 22 has the second filter take-up piece 223 on the outer surface of the first filter take-up piece 122, and the structure of the filter paper 23 is different. In addition, it has the same structure as the smoking article 1 with a filter of the first embodiment.

The filter 22 further includes a second filter take-up piece 223 which is a transparent roll which is wound around the outer peripheral surface of the first filter take-up piece 122 which is a gas permeable paper.

The transparent roll paper 223 is impermeable to the colored content liquid 152 of the fragrance capsule 15, and at least a part has a transparent portion. The transparent roll paper 223 is, for example, transparent as a whole, and is formed of the same material as the sheet-like base material of the filter paper 13 described in the first embodiment. The transparent roll paper 223 having at least a portion having a transparent portion means that the portion corresponding to the opening portion 23a of the filter paper 23 described later is transparent. The transparent transparent roll paper 223 is, for example, a polyolefin film such as cellophane or polypropylene film, a polyvinyl chloride film, or a cellulose acetate film. The transparent roll paper 223 can also form a liquid-impermeable layer by coating a resin such as nitrocellulose, ethyl cellulose, polyvinyl alcohol, or polyvinyl acetate on the outer side surface, the inner side surface, or both sides, or A liquid impermeable layer is formed using a substance having low affinity with the colored content liquid 152. Since the transparent roll paper 223 is impermeable to the colored content liquid 152, the colored content liquid 152 can be prevented from oozing out to the outer peripheral surface of the transparent roll paper 223, and the colored content liquid 152 can be prevented from adhering to the smoker's lips or hands.

The filter paper 23 is wound around the outer peripheral surface of the downstream end portion of the tobacco rod 11 and the outer peripheral surface of the filter 22, and the tobacco rod 11 is connected to the filter 22. The filter paper 23 has an opening portion 23a, and the opening portion 23a is an opaque portion 23b. The opening portion 23a of the filter paper 23 is configured in the same shape and arrangement as the transparent portion 13a of the filter paper 13 described in the first embodiment.

The opening portions 23a of the filter paper 23 are disposed to face the regions where the colored content liquid is released, respectively. When viewed from the center point of the cross section perpendicular to the longitudinal direction of the filter 22, the opening portions 23a of the filter paper 23 are arranged such that the angular interval between the adjacent opening portions 23a is 150 or less. The opening portion 23a of the filter paper 23 preferably has a shape in which the length W along the longitudinal direction of the filter is longer than the length L in the circumferential direction of the filter paper 23. The opening portion 23a has, for example, a rectangular shape having a length L of 3 mm and a length W of 5 mm. Although an example of the opening portion 23a having a rectangular shape is shown in Fig. 5, the shape of the opening portion 23a is not limited thereto, and may be, for example, a character, a geometric shape, a trademark, or the like. Further, it is preferable that the opening portion 23a of the filter paper 23 is less than 65% of the circumference of the filter paper 23. When the ratio of the opening portion 23a to the circumference of the filter paper 23 is too large, the strength of the filter paper 23 is lowered in the portion having the opening portion 23a, which is not preferable.

In the configuration in which the opening portion 23a of the filter paper 23 is disposed to face the region where the colored content liquid is discharged, the structure of the smoking article 2 with the filter shown in Figs. 5 and 6 is included. The arrangement of the hole portion 23a and the portion facing the fragrance capsule 15 is preferable. At this time, when the fragrance capsule 15 is broken and the colored content liquid 152 is released, the dyed portion can be easily visually recognized through the opening portion 23a.

The material constituting the filter paper 23 is not particularly limited, and for example, a material of a filter paper generally used in the manufacture of a smoking article with a filter can be used. The opening portion 23a of the filter paper 23 can be formed, for example, by cutting through a region other than the opaque portion 23b.

Further, the filter paper 23 preferably has a basis weight of 20 gsm to 100 gsm, and preferably has a basis weight of 25 gsm to 50 gsm, similarly to the filter paper 13 described in the first embodiment. For the same reason, the filter paper 13 preferably has a thickness of 15 μm to 80 μm, preferably 18 μm to 40 μm.

The smoking article 2 with a filter according to the second embodiment can obtain the same effects as the smoking article 1 with a filter according to the first embodiment. That is, for example, when the filter 12 is clamped and squeezed with the index finger and the thumb, and the fragrance capsule 15 inside the filter 12 is broken to release the colored content liquid 152 to the filter member 121, the smoker can pass the filter paper from the outside. The opening portion 23a of the 23 can easily visually confirm the filter take-up sheet 122 belonging to the air-permeable paper which rapidly develops a vivid color, and can quickly confirm the breakage of the fragrance capsule 15. Further, the filter paper 23 wound around the outer peripheral surface of the filter member 121 is provided with at least three opening portions 23a which are disposed apart from each other along the circumferential direction thereof, and are centered from the cross section perpendicular to the longitudinal direction of the filter 22. When viewed from the point of view, if the respective opening portions 23a are arranged such that the angular interval between the adjacent opening portions 23a is 150 or less, the smoker can visually confirm the release of the colored content liquid 152 of the fragrance capsule 15 to a higher probability. The inside of the filter 22 is in a state where the filter take-up sheet 122 of the breathable paper is dyed, that is, the state in which the fragrance capsule 15 is broken.

Further, in the fifth and sixth drawings, an example in which the air-permeable paper is wound around the filter member, and the transparent roll paper is wound on the air-permeable paper, and the filter paper is wound on the transparent roll paper is described, but the invention is not limited thereto.

Each of the test samples 1 to 3 was embedded in the portion having the fragrance capsule, and was pressed in the radial direction by applying a load of 15 N to the fragrance capsule to rupture the fragrance capsule. Next, after standing for one minute, the state in which the colored content liquid was oozing out to the filter take-up sheet was observed, and the color saturation (Saturation) ΔE [-] was measured. At this time, the color saturation was measured by SpectroEye of a measuring machine manufactured by X-Rite Inc. in accordance with JIS8781. Four test tests were performed for each of the test samples 1 to 3, and the average value thereof was shown in Table 1 as a test result of the color saturation ΔE [-]. Further, in (a), (b) and (c) of Fig. 13, a filter roll in which the colored content liquid oozes to the test sample 3 (FL3), the test sample 1 (FL1), and the test sample 2 (FL2) is schematically shown. Take the status of the film.

(3) Test results

From the test results shown in (a) to (c) of Fig. 13, it can be understood that among the test samples 1 and 2 having a gas permeability of 10000 C.U. and 30000 C.U., the colored content liquid is taken up for the filter. The bleed area (S1, S2) was 1.5 to 2 times larger than the bleed area (S3) of the test sample 3 having a gas permeability of 0 C.U. From this result, it is understood that the higher the gas permeability of the filter take-up sheet, the easier the colored content liquid diffuses on the surface of the filter. In addition, according to the test results shown in Table 1, the test samples 1, 2 are larger than the test sample 3, although the colored content liquid has a wider bleed area for the filter take-up sheet, but the color saturation ΔE is lower, but since The transparency is 30% or more and a sufficient value can be obtained.

Test Example 2: Viscosity of colored content liquid of a fragrance capsule

In the test example, test samples 4 to 6 in which a filter having a fragrance capsule was placed inside were prepared, and the influence of the viscosity of the colored content liquid of the fragrance capsule was evaluated.

(1) Production of test samples

(1-1) Production of test samples 4 to 6

Test samples 4, 5, and 6 were prepared in the same manner as in Test Sample 1, except that the amount of the tackifier added was changed so that the viscosity of the colored content liquid was 86 mPa‧s, 118 mPa‧s, and 162 mPa‧s, respectively. The viscosity was adjusted to 20 ° C in accordance with JIS-K7117-1, and was measured by a rotary viscometer (TVB-10M manufactured by TOKI SANGYO CO., LTD).

(2) Test method

Each of the test samples 4 to 6 was embedded in the portion having the fragrance capsule, and was pressed in the radial direction by applying a load of 15 N to the fragrance capsule to rupture the fragrance capsule. At this time, on the outer peripheral surface of each of the test samples 4 to 6, the colored content liquid was permeated to the two portions of the outer peripheral portion of the filter which were radially pressed. Next, after standing for one minute, the filter take-up piece of each test sample was removed, and the distance [mm] between the areas where the colored content liquid oozes out to the filter take-up piece was measured. Four test tests were performed on each test sample, and the average value thereof was shown in Fig. 14 as a test result.

(3) Test results

According to the results of Fig. 14, it is understood that the lower the viscosity of the colored content liquid of the fragrance capsule of each test sample, the shorter the distance between the areas where the colored content liquid oozes out to the filter take-up sheet. From this result, it is understood that the lower the viscosity of the colored content liquid of the fragrance capsule, the easier the colored content liquid diffuses on the surface of the air-permeable paper wound around the outer surface of the filter member.

Test Example 3: Air permeability of the paper and oil absorption according to the Kerm test method

In this test example, for each of the papers 1 to 7 manufactured by NIPPON PAPER PAPYLIA CO., LTD. shown in Table 2, the oil absorption [mm] was measured according to the Klim test method (JIS 8141) of the water absorption test method. .

(1) Test method

Each of the papers 1 to 7 was cut into a width of 15 mm and a length of 200 mm to prepare a test piece. Next, from a distance of 15 mm from the short side of each test piece, a marking was drawn with a pencil, and a jig overlapping between the marked line and the short side was mounted. The container was filled with a solvent of a general fragrance capsule of 23 ° C, that is, a medium chain fatty acid (MCT), and one end of each test piece not marked with a line was attached to a suspension. Next, it was confirmed that the marked lines of the respective test pieces became a straight line, and the test piece was quickly immersed in the MCT to the mark, and left for five minutes. Next, in the test piece, the height [mm] at which the MCT rises from the reticle is measured, that is, the oil absorption [mm] obtained by the Klim test method. Each paper was subjected to 10 tests, and the average value thereof was shown in Table 2 as a test result. Further, the time during which the test piece was immersed in the MCT was set to five minutes assuming the average smoking time of the smoking article with the filter attached.

(2) Test results

According to the results of Table 2, the test pieces of papers 1 to 5 having a gas permeability of 1000 C.U. to 30000 C.U. were able to obtain a high oil absorption of 18.3 mm to 30.6 mm. Further, the test piece of paper 2 to 5 having a gas permeability of 7000 C.U. to 30,000 C.U. can obtain a particularly high krim oil absorption of 23.3 mm to 30.6 mm. From this result, it is understood that the Km of the MCT having a high air permeability is higher by 1.5 times to 2 times than the test piece of the plain paper 24 of the paper 6, and the MCT is diffused to a larger area. Figure 15 is a graph showing the relationship between the density of paper and the oil absorption obtained by the Klim test. From this result, it is also known that paper having a low density generally has a high air permeability, so that the Km absorption of the MCT is high, and the MCT spreads to a larger area.
