The inventors of the present invention have a problem that a cigarette including a perfume capsule in the filter portion is difficult to know the position of the perfume capsule when the smoker breaks the perfume capsule when the cigarette wraps with an opaque plug winding paper or an opaque tip paper, and It was noted that after capsule crushing, there was a problem that it was not known that the capsule contents developed in the filter.

In order to visualize the fragrance capsules in the filter, when the transparent tip paper or the transparent plug winding paper is used, the above-described blindfold function (that is, the seam of the filter and the tobacco rod is not visible or the color of tar attached to the filter medium of the filter is not shown). Function to prevent damage). In addition, when the fragrance capsule is visualized using a transparent tip paper or a transparent plug winding paper, although the capsule breakage can be recognized, since the capsule contents are very small, it is not necessary to visually recognize that the capsule is sufficiently developed. it's difficult.

(b) the smoker can visually recognize the position of the capsule through the tip paper and plug wrapper when crushing the flavor capsule in the filter, and

(c) It is an object of the present invention to provide a cigarette having a tip paper and a plug winding paper which can visually recognize that the capsule contents liquid has developed in the filter through the tip paper and the plug winding paper.

Until now, cigarettes including fragrance capsules have been aimed at preventing the capsule contents released by the breakdown of the capsule from staining the plug winding paper and the tip paper. For example, a lipophilic solvent is used as the capsule contents. When using, oil-resistant oil is used suitably as a plug winding paper. On the other hand, the present inventors have completed the present invention by attaching the capsule contents solution to the translucent plug winding paper and causing stains having higher transparency to be generated on the plug winding paper.

That is, according to the present invention,

EMBODIMENT OF THE INVENTION Hereinafter, although this invention is demonstrated with reference to drawings, the following description aims at explaining this invention in detail, and is not intended to limit this invention.

1A and 1B are sectional views showing a part of the cigarette of the present invention. FIG. 1A shows a cigarette before crushing the flavor capsule 23, and FIG. 1B shows a cigarette after crushing the flavor capsule 23.

The cigarette shown in FIGS. 1A and 1B includes a filter rod 20 in which a perfume capsule 23 is accommodated in a hollow portion formed of a tobacco rod 10, two filter plugs 21a, 21b, and a plug winding paper 22. It is provided, and the tobacco rod 10 and the filter 20 are connected by the tip paper 30. As shown in FIG. The cigarette shown to FIG. 1A and 1B has a cylindrical shape as a whole like the cigarette with a normal filter.

The tobacco rod 10 is made of a tobacco filler 11 and a cigarette wrapper 12 surrounding the cigarette filler 11, like a normal cigarette, and has a diameter of 5 to 10 mm and a length of 40 to 80 mm, for example. Can be.

The filter 20 includes two filter plugs 21a and 21b spaced apart from each other and a plug wound paper 22 wound around the filter plug to form a hollow portion between the filter plugs 21a and 21b. ) And a perfume capsule 23 accommodated in the hollow portion between the filter plugs and holding the contents solution containing the perfume in the coating film. The filter 20 has a diameter substantially the same as that of the tobacco rod 10, and the length may be, for example, 15 to 40 mm, similarly to a normal filter.

In the cigarette of Figs. 1A and 1B, two filter plugs 21a and 21b are arranged through one hollow part, but n (n is an integer of 2 or more) filter plugs are arranged through (n-1) hollow parts. It may be sufficient, for example, n is 2-4, Preferably n is 2-3, More preferably, n is 2.

The filter plugs 21a and 21b may be made of a fibrous filter material such as cellulose acetate fibers, similar to a cigarette with a normal filter. The filter plug may be comprised only with a fibrous filter material, and may be comprised with a fibrous filter material and the raw material wound around it. The filter plug 21a on each side and the filter plug 21b on the suction port side may have the same material and structure, or may have different material and structure.

The plug winding paper 22 is wound around two filter plugs 21, and as a result, forms a hollow portion together with the two filter plugs 21a and 21b. The plug winding paper 22 is translucent and has an opacity of the degree which can recognize the fragrance capsule 23 located in a hollow part. That is, the plug winding paper 22 has an opacity such that a smoker can visually recognize the position of the perfume capsule when the smoke capsule breaks the perfume capsule in the filter. For this reason, the plug winding paper 22 is also equipped with the function of the blindfold which does not show the structure inside a filter. Moreover, when the capsule contents liquid discharged by the destruction of a perfume capsule adheres to the plug winding paper 22, the opacity falls and the visibility level of a perfume capsule increases. In other words, the plug wound paper 22 has increased transparency at the position where the capsule contents solution adheres, so that the outline of the broken perfume capsule is clearly visible. "The visibility level increases" means that the outline of the fragrance | flavoration capsule which was destroyed is seen clearly, and that an evaluation point increases according to the evaluation criteria described in Table 1 mentioned later specifically. Thereby, a smoker can visually recognize that the capsule contents liquid developed in the hollow part.

As described above, in the present invention, the capsule contents solution is attached to the translucent plug winding paper, and a stain having higher transparency is generated on the plug winding paper. Can visually recognize that. Thereby, a smoker can confirm a fragrance after confirming that the capsule content liquid fully developed in a hollow part.

In order to show the effect mentioned above, in the present invention, the plug winding paper 22 is specifically provided with the following three requirements.

(1) The plug winding paper has an impermeability to the capsule contents solution.

(2) The laminated paper composed of the plug winding paper and the tip paper has an opacity of 70% or less.

(3) The laminated paper composed of the plug winding paper and the tip paper has an opacity of at least 5% lower than before capsule destruction when the capsule contents liquid released by the fragrance capsule adheres.

In the present invention, the tip paper is preferably transparent, and when the tip paper is transparent, the opacity is generally 0.5 to 3%. As the transparent tip paper, for example, NatureFlex 23μ (Innovia) and NatureFlex 42μ (Innovia) can be used as the base film for the tip paper. For this reason, when the tip paper is transparent, the tip paper does not substantially affect the opacity of the laminated paper. Therefore, when the tip paper is transparent, the requirement of (2) is expressed as "the plug wound paper has an opacity of 70% or less", and the requirement of (3) indicates that the plug wound paper is broken of the perfume capsule. Has a opacity of at least 5% lower than that before capsule breakdown when the capsule contents released by the adhered.

Throughout this specification, opacity refers to the value measured according to JIS P8138A (1976).

Specifically, whether or not the plug winding sheet satisfies the requirement of (1) can be determined as follows. In other words,

The laminated sheet is formed by overlapping the plug winding paper and the test paper, and the opacity of the laminated paper is measured on the test paper side,

Drop the capsule contents on the side of the plug winding paper, measure the opacity of the laminated paper on the test paper side,

The difference in opacity is obtained by subtracting the opacity after dropping the capsule contents from the opacity before dropping the capsule contents.

When the difference is less than 10%, the plug winding paper is evaluated as impermeable to the capsule contents solution, and when the difference is more than 10%, the plug winding paper is impermeable to the capsule contents solution. It is evaluated that there is no (see Example 2 described later). Therefore, in the present invention, the term "having impermeability" includes the case of having impermeability but extremely low permeability in addition to the case of having complete impermeability (see Table 3 below). The measurement of opacity here is also performed according to JIS P8138A (1976). The "test paper" used here is an opaque paper having a function as a filter paper capable of absorbing the liquid when the liquid penetrates the plug winding paper. For example, a paper having a opacity of 80 to 33 33 [mu] m or more can be used. For example, 37 hundred paper (Japan Paper Papyria Co., Ltd.) is mentioned.

It can be specifically determined as follows whether or not the laminated paper composed of the plug winding paper and the tip paper satisfies the requirements of (2). That is, a laminated paper is formed by overlapping a plug winding paper and a tip paper, and the opacity of the laminated paper is measured on the tip paper side (see Example 3 described later). The measurement of opacity here is also performed according to JIS P8138A (1976). In the present invention, the opacity (that is, the opacity before adhesion of the capsule contents solution) measured in this way is 70% or less, preferably 5 to 70%, more preferably 10 to 40%, and more preferably 15 It is-40%. If the opacity exceeds 70%, it is difficult to visually recognize the perfume capsule through the plug winding paper and the tip paper.

It can be specifically determined as follows whether or not the laminated paper composed of the plug winding paper and the tip paper satisfies the requirements of (3). In other words,

Overlapping the plug winding paper and the tip paper to form the laminated paper, measuring the opacity of the laminated paper on the tip paper side,

Drop the capsule contents on the plug winding side, measure the opacity of the laminated paper on the tip paper side,

The difference in opacity is obtained by subtracting the opacity after dropping the capsule contents solution from the opacity before dropping the capsule contents solution (see Example 3 to be described later). The measurement of opacity here is also performed according to JIS P8138A (1976). In this invention, the difference of the opacity calculated | required in this way is 5% or more, Preferably it is 5-30%, More preferably, it is 10-30%. If the difference in opacity is less than 5%, the decrease in the opacity of the laminated paper is not sufficient, and it is difficult to recognize that the capsule contents liquid released by the breakage of the capsule has spread in the filter hollow.

Regarding the requirements of (2) and (3), before manufacturing the cigarette, the opacity of the laminated paper formed by stacking the plug winding paper and the tip paper may be measured, and after the cigarette is manufactured, the plug winding paper and the tip paper are adhered. The laminated paper in the closed state may be cut out at the position of the hollow portion to measure the opacity of such laminated paper. In the latter case, the adhesive is included in the laminated paper, but since the transparent adhesive (for example, an emulsion-based adhesive) is generally used for bonding the plug winding paper and the tip paper, the influence of the adhesive on the opacity can be ignored. have.

More specifically, the plug wound paper 22 may use a paper having an opacity of 5 to 40%, a smoothness of 500 to 2500 sec, and an ash content of 0 to 5%. Preferably, as the plug wound paper 22, a paper having an opacity of 20 to 40%, a smoothness of 500 to 2500 sec, and an ash of 0 to 5% can be used. More specifically, the plug wound paper 22 may be made of glassine paper and parchment paper that satisfy the above conditions. Preferably, the plug winding paper 22 can use glassine paper which satisfy | fills the said conditions. If the opacity exceeds 30%, it is not preferable in view of visual recognition of the perfume capsule. If the smoothness is less than 500 sec, it is not preferable from the viewpoint of impermeability to the capsule contents solution. Moreover, when ash content exceeds 5%, it is unpreferable from a viewpoint of opacity increase. The plug winding paper 22 may be 40-80 micrometers thick, for example.

The plug wound paper 22 forms a specific shape region having water repellency or oil repellency on its inner surface (surface on the hollow portion side), and the contents liquid released by the destruction of the perfume capsule. At the time of attachment, the specific shape may be treated to float. The region having water repellency can be formed by applying paraffin, silicone or the like, and the region having oil repellency can be formed by applying wax, paraffin, carboxymethyl cellulose, latex or the like. These materials can be applied by coating onto a plug wound paper using a printing technique. Specific shapes include symbols; Shapes such as circles, triangles, squares, and stars; Arbitrary shapes, such as letters, such as an alphabet, may be sufficient.

In the cigarette of FIGS. 1A and 1B, the flavor capsule 23 is accommodated in the hollow portion between the filter plugs. One perfume capsule may be accommodated per hollow part, and two or more perfume capsules (for example, 2-10) may be accommodated.

The fragrance capsule is comprised from the coating liquid 23a and the inner liquid 23b containing a fragrance | flavor. For the film 23a, for example, starch, dextrin, polysaccharide, agar, gellan gum, gelatin, various natural gelling agents, glycerin, and the like can be used, and also fragrances or coloring agents can be included. Even if the perfume capsule is surrounded by a plug winding paper having an opacity, it is preferable that the perfume capsule is colored so that a smoker can recognize when crushing the perfume capsule, and the coating 23a preferably contains a coloring agent, for example, blue No. 1 or the like. Do. As a fragrance of the liquid solution 23b, menthol, plant essential oil, etc. can be used, for example. As the solvent of the liquid solution 23b, a solvent suitable for perfume can be used, and medium-chain fatty acid triglyceride (MCT) (specifically, tricapryl / glycerin capric acid), propylene glycol, water, ethanol, etc. Can be used. The contents solution may further contain other additives such as other solvents, colorants, emulsifiers and thickeners.

Although the manufacturing method of a perfume capsule is not specifically limited, For example, when a dropping method is used, a perfume capsule which has a seamless film can be manufactured. In this method, by using the double nozzle, the liquid solution is discharged simultaneously from the inner nozzle and the liquid film material is discharged from the outer nozzle, so that the coating liquid can be wrapped without the joint. A perfume capsule can be 1.5-7.0 mm in diameter, for example.

When manufacturing the cigarette of this invention, the fragrance | flavor contained in a cigarette is determined first, the solvent suitable for dissolving a fragrance | flavor is selected according to the kind of fragrance | flavor, About this solvent, (1)-(3) mentioned above about this solvent Can be selected to meet the requirements of For example, when menthol is contained in a cigarette, a medium chain fatty acid triglyceride is selected as a solvent, and a paper which satisfies the requirements of (1) to (3) described above for this solvent, for example, 40.0 thick white ( Glassine (Japan Paper Papyria Co., Ltd .; Glassine), 25.8 night ball white Glassine (Japan Paper Papyria Co., Ltd .; Glassine), Drift W34.9 (Oji Special Paper Co., Ltd.) J) high transparency glassine 40 (Japan Paper Papyria Co., Ltd .; glassine), etc. can be selected (refer Table 4 and Table 6).

In the cigarettes of FIGS. 1A and 1B, the tip paper 30 is preferably a liquid solution impermeable. In addition, it is preferable that the tip paper is transparent. As such tip paper, a transparent cellophane can be used.

The tip paper 30 is adhere | attached with an adhesive agent so that the whole plug winding paper 22 and the part of the cigarette wrapping paper 12 may be covered. The adhesive is preferably colorless and transparent so as not to affect the visibility level of the perfume capsule. For example, an emulsion adhesive may be used. The tip paper 30 may be, for example, 20-50 mm in length in the axial direction of the tobacco rod and 10-100 μm in thickness. Similar to a cigarette with a normal filter, the tip paper may have a plurality of small holes for venting (ventilation holes) in one row, in a plurality of rows or irregularly along the circumferential direction of the cigarette. The tip paper 30 may be coated in a region other than the hollow portion, for example, white paper printing.

(12) High transparency glassine 40 (JT high transparency glassine 40; Nippon Paper Papyria Co., Ltd., glassine paper)

Opacity 15-25%, smoothness 1500sec or more, ash 0-5%

2. Evaluation method

As the addition liquid, medium chain fatty acid triglyceride (MCT) (tricapryl / glycerine capric acid), propylene glycol (PG), and water were used.

Evaluation was performed under 23 degreeC, 50% of humidity, and a standard light source.

(1) before liquid dropping

The plug wound paper was piled up with tip paper (37 hundred paper; Nippon Paper Papyria Co., Ltd.) (test paper), and the opacity (%) of the obtained laminated paper was measured by the Hunter method (JIS P 8138A) on the tip paper side.

(2) after the liquid dropping

70 microliters of liquid was dripped at the plug winding paper side of the laminated paper mentioned above. After 2 minutes from the drop of liquid, the liquid remaining on the surface of the plug winding paper was wiped off. Thereafter, the opacity (%) on the tip paper side was measured by the Hunter method (JIS P 8138A).

The difference between the opacity (%) after the liquid dropping and the opacity (%) before the liquid dropping was calculated as the "change amount of opacity". Opacity was evaluated as shown in the following table based on the "change amount of opacity".

When liquid is water, since it dries over time, an opacity cannot be measured and an impermeability was evaluated by the external appearance instantaneously by the evaluation criteria of Table 3.

3. Evaluation result

"Change amount of opacity" and "evaluation of opacity" are shown below about various plug winding sites.

Plain paper 24, N250, NPWS, P10000C, and P20000C exhibit permeability to any liquid and are not suitable for use as a plug winding paper. NatureFlex 23μ, 50NFB, Drift W34.9, Grafan, and Highly Transparent Glassine 40 were impermeable to any liquid. Although glassine 25.8 showed some permeability to medium-chain fatty acid triglycerides, it is considered that there is no problem in use as a plug winding paper. Since glassine 25.8 exhibited permeability to water, water cannot be used as a solvent for perfume capsules. Glassine 40 had impermeability to any liquid other than water.

Example 3: Plug Winding Opacity  change

1. Evaluation method

In the present Example, the plug winding paper used in Example 2 was superimposed with the transparent tip paper NatureFlex 23 micro, and the change of the opacity by adhesion of liquid was evaluated. The liquid same as used in Example 2 was dripped, and evaluation was performed by the method similar to Example 2.

The difference between the opacity (%) after the liquid dropping and the opacity (%) before the liquid dropping was calculated as the "change amount of opacity". The amount of change in opacity was evaluated in relation to the appearance (transparency) as shown in the table below.

As shown in Table 5, when the amount of change in opacity is 5% or more, it can be visually recognized that transparency has increased.

2. Evaluation result

"Change amount of opacity" and "evaluation" are shown below about various plug windings.

Plain paper 24, N250, NPWS, P10000C, and P20000C had a large change in opacity even after dropping any liquid, but from the results of Example 2, they showed permeability to any liquid, which is not suitable as a plug winding paper. not.

NatureFlex 23μ does not show a change in opacity of 5% or more, and therefore is not suitable as a plug winding paper.

Since 50NFB is opaque, when this paper is used, since the position of a fragrance capsule cannot be recognized, it is not suitable as a plug winding paper.

Drift W34.9 had an opacity of 37.2% before dropping, and also showed an amount of change in opacity of 5% or more after dropping of any liquid, and visually recognized that transparency was increased. Drift W34.9 also exhibited impermeability to any liquid (see results of Example 2). From this fact, Drift W34.9 can be used as a plug winding paper.

Graphene is not suitable as a plug winding paper because it does not exhibit an amount of change in opacity of 5% or more.

Glassine 25.8 had an opacity of 20.9% before dropping and a change in opacity of 5% or more after dropping of medium-chain fatty acid triglyceride (MCT) and propylene glycol (PG), and visually recognized that transparency was increased. Glassine 25.8 also showed impermeability to medium chain fatty acid triglycerides (MCT) and propylene glycol (PG) (see results in Example 2). From this fact, glassine 25.8 can be used as a plug winding paper when these liquids are used as a perfume-containing liquid.

Glassine 40 had an opacity of 31.2% before dropping and a change in opacity of 5% or more after dropping of medium chain fatty acid triglyceride (MCT), propylene glycol (PG) and water, and visually recognized that transparency was increased. . In addition, glassine 40 exhibited impermeability to medium chain fatty acid triglyceride (MCT), propylene glycol (PG) and water (see the results of Example 2). From this fact, glassine 40 can be used as a plug winding paper when these liquids are used as a perfume-containing liquid.

The high transparency glassine 40 had an opacity of 16.2% before dropping and a change in opacity of 5% or more after dropping of medium-chain fatty acid triglyceride (MCT), and visually recognized that transparency was increased. In addition, high transparency glassine 40 showed impermeability to any liquid (refer the result of Example 2). From this fact, the high transparency glassine 40 can be used as a plug winding paper.
