Description

cigarette

The present invention relates to a cigarette having a filter for a cigarette containing a fragrance capsule.

In the past, the flavor capsules were placed in a filter for cigarettes, and the flavor capsules were crushed during use, and the flavor of the content liquid was tasted during smoking, and the taste of the cigarette butts after digestion was masked (Patent Documents 1 and 2). The details of the flavor capsule are described, for example, in Patent Document 3.

The tipping paper and the insert paper take-up paper make the connection between the filter and the tobacco rod not visible. Because the smoking causes the tar to adhere to the filter material of the filter, in order to protect the role of the tar color from being seen, the general system is Use opaque paper. In the case of the charcoal filter, in addition to the above functions, the opaque outer paper and the insert take-up paper also function as a role in which the activated carbon color is not seen.

On the other hand, paper is taken up using a transparent outer layer paper and a transparent insert, and the inside of the filter is visualized (Patent Documents 4 to 6).

In order to visualize the inside of the filter, Patent Document 4 discloses that a transparent material is used as the outer layer paper and the insert paper is taken up, and opaque coating is applied to a part of the outer paper to impart a masking function. In Patent Document 4, the transparent material is exemplified by polypropylene, polyvinyl chloride, cellulose acetate film, polyethylene terephthalate, polyoxyethylene, polyethylene, cellophane, and natureflex (registered Trademark) and polyacetic acid. Further, Patent Document 4 discloses that if the inside of the filter can be visualized, in order to provide an aesthetic effect of the filter, the outer paper and the insert take-up paper can be translucent by coloring.

Patent Document 5 discloses the use of a transparent film material as a tip paper and a filter roll paper, and the fragrance particles in the filter can be visually observed. The materials of the transparent film are exemplified by polypropylene, polyvinyl chloride and cellulose acetate. membrane.

Patent Document 6 discloses that a transparent material is used as the outer layer paper and the insert winding paper in order to visualize the extraction effect of the harmful substance.

The present inventors focused on cigarettes containing a fragrance capsule in a filter portion. If an opaque insert is used to take up the paper and the opaque outer paper roll, it is difficult for the smoker to know the position of the fragrance capsule when the smoker crushes the fragrance capsule. And, after the capsule is broken, the problem that the capsule content liquid expands in the filter is not known.

In order to visualize the flavor capsules in the filter and use the transparent outer paper and the transparent insert to take up the paper, the above hiding function is damaged (that is, the connection between the filter and the tobacco rod is not seen, and the filter is attached to the filter. The color of the tar of the filter material is not seen.) In addition, when the transparent capsule paper and the transparent insert are used to take up the paper to visualize the flavor capsule, even if the capsule is broken In the case of a small amount of liquid in the capsule, it is difficult to visually confirm that the content liquid is sufficiently expanded in the hollow portion.

Here, the object of the present invention is to provide a cigarette having an outer layer paper and a card take-up paper, which has the following features: (a) the outer paper and the insert take-up paper maintain the masking function, and (b) the smoker crushes the filter. In the case of the fragrance capsule, the paper can be visually confirmed by the outer paper and the insert, and (c) the capsule is broken, and the outer paper and the insert are taken up to visually confirm that the capsule content liquid expands in the filter.

Heretofore, the cigarette containing the flavor capsule is preferably such that the capsule content liquid released by the destruction of the capsule does not cause bleeding on the insert take-up paper and the outer layer paper. For example, when a lipophilic solvent is used as the capsule content liquid, it is preferred. To take up paper with oil-resistant paper as a plug-in. On the contrary, the inventors of the present invention completed the present invention by attaching a capsule content liquid to a translucent inserting paper to produce a bleeding having higher transparency in the insert winding paper.

That is, a cigarette according to the present invention includes: a tobacco rod comprising a tobacco filler and a tobacco roll wrapped around the tobacco filler; and a filter comprising a plurality of filter inserts arranged at a distance from each other; Rolling up the paper around the filter insert in such a manner as to form a hollow portion between the filter inserts; and in the hollow portion, and containing the fragrance a fragrance capsule in which the content liquid is maintained in the film; and an outer layer paper wrapped around the tobacco rod and the filter in a manner of connecting the tobacco rod and the filter; the insert winding paper does not wear the content liquid The opacity of the laminated paper comprising the insert take-up paper and the outer layer paper is (i) 70% or less before the fragrance capsule is broken, and (ii) the content liquid released by destroying the fragrance capsule is attached to the insert. When taking up paper, reduce it by 5% or more.

The cigarette according to the present invention has the following features: (a) the outer paper and the insert take-up paper maintain the masking function, and (b) when the smoker crushes the spice capsule in the filter, the outer paper and the insert take up the paper, and After the capsule position can be visually confirmed and (c) the capsule is broken, the capsule content liquid is infiltrated on the insert take-up paper, whereby the capsule content liquid can be visually confirmed to expand in the filter.

The invention is described below with reference to the drawings, but the following description is intended to illustrate the invention and not to limit the invention.

1A and 1B are cross-sectional views showing a part of the cigarette of the present invention. Fig. 1A shows the cigarette before the fragrance capsule 23 is crushed, and Fig. 1B shows the cigarette after the fragrance capsule 23 is crushed.

The cigarettes shown in FIGS. 1A and 1B have a tobacco rod 10, a filter 20 in which a fragrance capsule 23 is accommodated in a hollow portion formed by the two filter inserts 21a and 21b and the insert take-up paper 22, and tobacco Stick 10 and filter 20 Connected by the outer paper 30. Similarly to the cigarettes generally having a filter, the cigarettes shown in Figs. 1A and 1B have a cylindrical shape as a whole.

Like the conventional cigarette, the tobacco rod 10 is composed of the tobacco filler 11 and the tobacco roll paper 12 wrapped around it, and may have, for example, a diameter of 5 to 10 mm and a length of 40 to 80 mm.

The filter 20 includes two filter inserts 21a and 21b which are disposed to be spaced apart from each other with a hollow portion interposed therebetween, and an insert take-up paper 22 which is formed by winding a hollow portion between the filter inserts 21a and 21b. Around the mouth insert; the capsule 23 is received in the hollow portion between the filter inserts, and the content liquid containing the fragrance is maintained in the film. The filter 20 has the same diameter as the tobacco rod 10 and has the same length as a general filter, for example, 15 to 40 mm.

In the cigarettes of Figs. 1A and 1B, the two filter inserts 21a and 21b are arranged with one hollow portion interposed therebetween, but n (n is an integer of 2 or more) filter inserts are interposed (n-1) It is also possible to arrange the hollow portion, for example, n is 2 to 4, preferably n is 2 to 3, and more preferably n is 2.

The filter inserts 21a and 21b can be composed of a fibrous filter material such as cellulose acetate fibers, similarly to a cigarette generally having a filter. The filter insert may be composed only of a fibrous filter material, or may be composed of a fibrous filter material and a material paper wrapped around the fiber. The filter insert 21a on the filament side and the filter insert 21b on the suction side may have the same material and structure, and may have different materials and configurations.

The insert take-up paper 22 is wrapped around the two filter inserts 21, and as a result, the two filter inserts 21a and 21b simultaneously form a hollow portion. The insert take-up paper 22 is translucent and has a fragrance capsule that can visually confirm the inside of the hollow portion. The degree of opacity of 23. That is, the insert take-up paper 22 has an opacity that allows visual confirmation of the position of the perfume capsule when the smoker crushes the perfume capsule in the filter. Therefore, the insert take-up paper 22 also has a covering function, so that the structure inside the filter is not seen. In addition, if the insert take-up paper 22 adheres to the capsule content liquid released by the fragrance capsule, the opacity thereof is lowered and the visibility of the fragrance capsule is increased. That is, the transparency of the insert take-up paper 22 at the position where the capsule content liquid is attached is increased, and the outline of the damaged flavor capsule becomes apparent. The "increased visibility", that is, the outline of the damaged flavor capsule is clearly visible. Specifically, the evaluation points evaluated in accordance with the evaluation criteria described in Table 1 below will increase. Thereby, the smoker can visually confirm the expansion of the capsule content liquid in the hollow portion.

Thus, in the present invention, the capsule content liquid is attached to the translucent insert-wound paper, and the insert-wound paper is produced to have a higher transparency, and the capsule content can be visually confirmed by the enlargement of the bleeding. The expansion of the liquid in the hollow. Thereby, the smoker can confirm that the capsule content liquid is fully expanded in the hollow portion, and the flavor can be tasted.

In order to exert the above effects, the insert take-up paper 22 of the present invention specifically has the following three requirements:

(1) The insert take-up paper has a non-penetration property to the capsule content liquid.

(2) The laminated paper composed of the insert take-up paper and the outer paper has an opacity of 70% or less.

(3) When the laminated paper composed of the insert take-up paper and the outer paper adheres to the capsule content liquid released by the fragrance capsule, it has a low opacity of 5% or more as compared with that before the capsule is broken.

In the present invention, the outer layer paper is preferably transparent, and when the outer layer paper is transparent, the opacity is generally from 0.5 to 3%. As the transparent outer layer paper, for example, NatureFlex 23μ (Innovia), NatureFlex 42μ (Innovia) can be used as the base film for the outer layer paper. Therefore, when the outer paper is transparent, the outer paper does not substantially affect the opacity of the laminated paper. Therefore, when the outer paper is transparent, the requirement of (2) is "the entanglement of the insert take-up paper has 70% or less", and the requirement of (3) "the insert roll paper is attached with the capsule released by the damaging capsule. When the content liquid is used, it has a lower opacity of 5% or more than before the capsule is destroyed.

Throughout the specification, opacity means a value measured in accordance with JIS P8138A (1976).

Whether the plug-in roll-to-roll paper meets the requirements of (1), specifically, it can be judged in the following manner. That is, the overlapping insert takes up the paper and the test paper to form a laminated paper, the opacity of the laminated paper is measured from the test paper side, the capsule content liquid is dropped from the side of the inserting paper, and the opacity of the laminated paper is measured from the side of the test paper. The opacity after dropping the capsule liquid is subtracted from the opacity before dropping the capsule content liquid, thereby obtaining the opacity difference. When the difference is less than 10%, the insert winding paper is evaluated as having no liquid for the capsule content. When the difference is more than 10%, the insert winding paper is evaluated as having no penetration property with respect to the capsule content liquid (see Example 2 to be described later). Therefore, in the present invention, "having non-penetration" includes non-penetrability but is observed to be extremely non-penetrative. The case of micro-permeability (refer to Table 3 below). The measurement of opacity here is also carried out in accordance with JIS P8138A (1976). The "test paper" used herein is an opaque paper having a function as a filter paper which can absorb the liquid when the liquid penetrates the insert, for example, a paper having a thickness of 33 to 53 μm having an opacity of 80 or more can be used, for example, Take 37 white base paper (Japan Paper Papylia Co., Ltd.).

Whether the laminated paper composed of the insert take-up paper and the outer paper satisfies the requirements of (2), specifically, can be judged in the following manner. That is, the laminated paper is overlapped with the outer paper to form a laminated paper, and the opacity of the laminated paper is measured from the outer paper side (see Example 3 to be described later). The measurement of opacity here is also carried out in accordance with JIS P8138A (1976). In the present invention, the opacity thus measured (i.e., the opacity before attaching the capsule content liquid) is 70% or less, preferably 5 to 70%, more preferably 10 to 40%, still more preferably 15 to 40. %. If the opacity exceeds 70%, it is difficult to visually confirm the perfume capsule by taking up the paper and the outer paper through the insert.

Whether the laminated paper composed of the insert roll paper and the outer paper meets the requirements of (3), specifically, it can be judged in the following manner. That is, the overlapping insert winds up the paper and the outer paper to form a laminated paper, the opacity of the laminated paper is measured from the outer paper side, the capsule content liquid is dropped from the side of the paper taken by the insert, and the opacity of the laminated paper is measured from the outer paper side. The opacity after dropping the capsule content liquid is subtracted from the opacity before dropping the capsule content liquid, thereby obtaining the opacity difference (refer to Example 3 described later), where the opacity is also measured in accordance with JIS P8138A (1976). get on. In the present invention, the opacity difference thus obtained is 5% or more, preferably 5 to 30%, more preferably 10 to 30%. When the opacity is less than 5%, the decrease in the opacity of the laminated paper is not sufficient, and it is difficult to confirm that the capsule content liquid released from the broken capsule spreads in the hollow portion of the filter.

For the requirements of (2) and (3), the opacity of the laminated paper formed by the overlap of the insert take-up paper and the outer paper may be measured before the cigarette is manufactured, and the insert take-up paper may be cut from the position of the hollow portion after the cigarette is manufactured. The laminated paper is in a state of being attached to the outer layer paper, and the opacity of the laminated paper is measured. In the latter case, although the laminated paper contains an adhesive, the insert take-up paper and the outer paper are generally followed by a transparent adhesive (for example, an emulsion-based adhesive), so that the adhesive does not affect the transparency and can be ignored.

More specifically, the insert take-up paper 22 may use paper having an opacity of 5 to 40%, a smoothness of 500 to 2500 sec, and an ash of 0 to 5%. The insert take-up paper 22 preferably uses paper having an opacity of 20 to 40%, a smoothness of 500 to 2500 sec, and an ash of 0 to 5%. More specifically, the insert take-up paper 22 can use glassine paper or parchment paper which satisfies the above conditions. It is preferable to use the cellophane paper 22 which satisfies the above conditions. If the opacity exceeds 30%, it is less preferred from the viewpoint of visually confirming the flavor capsule. Further, if the smoothness is less than 500 sec, it is not preferable from the viewpoint of the non-penetration of the capsule content liquid. In addition, when the ash content exceeds 5%, it is not preferable from the viewpoint of an increase in opacity. The insert take-up paper 22 may have a thickness of, for example, 40 to 80 μm.

The insert take-up paper 22 can perform the following treatment on the inner side surface thereof The surface of the empty portion side is provided with a region having a specific shape of water repellency or oil repellency, whereby the specific shape is floated when the content liquid released by the fragrance capsule is broken. A water-repellent region can be formed by coating paraffin, ruthenium or the like, and a oil-repellent region can be formed by coating wax, paraffin, carboxymethylcellulose, latex or the like. These materials can be applied to the insert take-up paper by printing techniques and coated. The specific shape may be a mark; a circle, a triangle, a square, a star, or the like; an arbitrary shape such as a letter or the like.

In the cigarettes of Figs. 1A and 1B, the fragrance capsule 23 is housed in a hollow portion between the filter inserts. Each hollow portion can accommodate one spice capsule, and can also accommodate a plurality of (for example, 2 to 10) perfume capsules.

The fragrance capsule 23 is composed of a film 23a and a content liquid 23b containing a fragrance. The film 23a may, for example, be starch, dextrin, polysaccharide, cold weather, gellan gum, gelatin, various natural gelling agents, glycerin or the like, and may contain a perfume or a coloring material. Even if it is surrounded by the insert paper having the opacity, the fragrance capsule is preferably colored so that the user can confirm that the film 23a is crushed, and the film 23a preferably contains a coloring material such as Blue No. 1. As the fragrance of the content liquid 23b, for example, menthol, plant essential oil or the like can be used. As the solvent of the content liquid 23b, a solvent suitable for the fragrance can be used, and a medium chain fatty acid triglyceride (MCT) (specifically, caprylic/cabric triglyceride), propylene glycol, water, or the like can be used. Ethanol and the like. The content liquid may contain other additives such as other solvents, pigments, emulsifiers, and tackifiers.

The method for producing the flavor capsule is not particularly limited, but a flavor capsule having a seamless film can be produced, for example, by using a dropping method. Double in the method The liquid nozzle is discharged from the inner nozzle by the inner nozzle, and the liquid film material is simultaneously discharged from the outer nozzle, thereby allowing the coating liquid to wrap the content liquid without seams. The fragrance capsule may have a diameter of, for example, 1.5 to 7.0 mm.

When the cigarette of the present invention is produced, the flavor contained in the cigarette is first determined, and the solvent suitable for dissolving the fragrance is selected according to the type of the fragrance, and the insert-wound paper satisfying the above requirements (1) to (3) can be selected for the solvent. For example, when the cigarette contains menthol, the solvent may be selected from medium chain fatty acid triglyceride, and the paper satisfying the above requirements (1) to (3) for the solvent, for example, 40.0 white thick Glassis (Japan Paper Papylia Co., Ltd.) may be selected. : cellophane), 25.8 white thin Glassine (Japan Paper Papylia Co., Ltd.: cellophane), DREEP W34.9 (Prince Special Paper Co., Ltd.: parchment), JT High Transparent Glassine 40 (Japan Paper Papylia Co., Ltd.: cellophane) (Refer to Table 4 and Table 6).

In the cigarettes of Figs. 1A and 1B, the outer layer paper 30 is preferably impervious to the content liquid. Further, the outer layer paper is preferably transparent. Such a layer of paper can be used in transparent celluloid.

The outer layer paper 30 is followed by an adhesive in such a manner as to cover the entire portion of the card take-up paper 22 and the portion of the cigarette paper 12. The subsequent agent is preferably colorless and transparent without affecting the testability of the perfume capsule, and for example, an emulsion-based adhesive can be used. The outer paper 30 such as a tobacco rod may have an axial length (width) of 20 to 50 mm and a thickness of 10 to 100 μm. As with the cigarettes generally having a filter, the outer layer of paper can be provided with a large number of rows, a plurality of rows or irregular small openings for ventilation (vent holes) along the circumferential direction of the cigarette. The outer layer paper 30 can be applied in a region other than the hollow portion, for example, printed on a white background.

2. Manufacture of filters

The filter shown in Fig. 2 was produced by winding the paper using the above-mentioned insert. The filter is composed of a filter insert 21a on the filament side (left side), a filter insert 21b on the suction side (right side), a plug-in take-up paper 22, and a fragrance capsule 23.

The "filament plug 21a" on the filament side is composed of a filter material of Non-Wrap-Acetate (ATK2010-02) (excluding material paper), and has a length L1 of 11 mm and a circumference of 24.1 mm. The "filter inlet side plug 21b" is composed of an Acetate tow (2.8Y35000) filter material and a P10000C material paper, and has a length L2 of 10 mm and a circumference of 24.1 mm. The length (S) of the hollow portion formed by the two filter inserts and the insert roll paper was 6 mm. The fragrance capsule 23 is composed of a content liquid 23b containing a medium chain fatty acid triglyceride (octanoic acid/capric triglyceride) and a fragrance (menthol and plant essential oil), and a film 23a based on a polysaccharide (starch). The capsule D has a diameter D of 4.5 mm. Starch (20% by weight) as a film substance The content liquid (80% by weight) was mixed, and the flavor capsule was prepared by dropping. The total length (Lf) of the manufactured filter was 27 mm.

Using the FLR roll wrapping machine (ND-5RC, Sanjo Machinery Co., Ltd.), the two filter inserts and the fragrance capsules were wrapped in the insert take-up paper 22 as shown in Fig. 2 .

3. Manufacture of cigarettes

The cigarette shown in Fig. 3 was produced using the filter manufactured as described above. The cigarette is composed of "tobacco stick 10", "filter 20" and "outer paper 30".

"Tobacco Stick" is a tobacco rod made by Mild Seven, a brand sold by the company. The tobacco rod has a size of (Lr) 57 mm and a circumference of 24.8 mm. The "filter" is shown in Fig. 2, and its total length (Lf) is 27 mm. For the "outer paper", NatureFlex 23μ (Innovia) was used as the base film, and the white paper on both ends of the outer paper was printed by TANNPAPIER GmbH to a thickness of 10 mm for the outer paper processor. The outer paper length (Lt) was 32 mm, and the white base portion length (Lt1 and Lt2) was 10 mm.

An EVA emulsion can be used for the outer layer paste. Cigarettes A and B were produced from the filters A and B using a tobacco wrapping machine (HAUNI Protos M5). Further, cigarettes C to G were produced by hand wrapping from the filters C to G.

4. Evaluation results

The visibility (visibility) of the cigarette capsule was visually evaluated. The evaluation was carried out under a standard light source at 23 ° C, a humidity of 50%.

(1) Two cigarettes A to G were prepared separately.

(2) In one of the two, the capsule is crushed using a needle-nosed pliers.

(3) Place the cigarette with the crushed capsule on the table for 5 minutes.

(4) Place the placed cigarette on a commercially available coffee paper to visually score the visibility of the capsule.

The table below is a benchmark for scoring.

(5) Cigarettes before crushing were also evaluated in the same manner. From the difference between the score and the score obtained in (4), the "change in visibility" is calculated.

(6) Evaluation was performed by five evaluators, and the results of the visual evaluation were as follows. The table below shows the visual evaluation results combined with the opacity measurement results. The measurement result of opacity is the following Example 3 (Table 6) The results obtained are recorded here.

In cigarette C, the capsule cannot be visually confirmed before crushing, so 50NFB (oil resistant paper) is not suitable for the insert winding paper. In the cigarette F, the capsule can be visually and clearly confirmed after being crushed before crushing, so the NatureFlex 42μ does not have a covering function, and is not suitable for the insert winding paper. On the other hand, in cigarettes A, B, D, E and G, the capsule can be visually confirmed before the crushing (score 2 to 3), and if the capsule is crushed, the content liquid in the capsule is attached to the insert take-up paper, so that the capsule It can be confirmed visually more clearly.

(Example 2: The liquid of the insert take-up paper is not penetrating).

In the present embodiment, the liquid impermeability of the various insert take-up sheets was evaluated.

2. Evaluation method

Medium chain fatty acid triglycerides (MCT) (caprylic/capric triglyceride), propylene glycol (PG) and water are used.

The evaluation was carried out under a standard light source at 23 ° C, a humidity of 50%.

(1) before dropping the liquid

The insert take-up paper was overlapped with the outer paper (37 white paper: Nippon Paper Papylia Co., Ltd.) (test paper), and the opacity (%) of the obtained laminated paper was measured by the Hunter method (JIS P 8138A) from the outer paper side.

(2) After dropping the liquid

70 μl of the liquid was dropped on the side of the insert paper of the above laminated paper. After the liquid was dropped for 2 minutes, the plug was swept to take up the liquid remaining on the surface of the paper. The opacity (%) was then measured by the Hunter method (JIS P 8138A) from the outer paper side.

The "change in opacity" was calculated from the difference between the opacity (%) after dropping the liquid and the opacity (%) before dropping the liquid. The non-penetration system is evaluated according to the following table according to the "change in opacity".

When the liquid was water, the opacity could not be measured because it was dried over time, and the non-penetrability was evaluated instantaneously according to the evaluation criteria of Table 3.

The following shows the "change in opacity" and "evaluation of non-penetration" of various plug-in rolls.

Plain paper 24, N250, NPWS, P10000C, and P20000C all show transparency to liquids, so they are not suitable for use in insert winding paper. NatureFlex 23μ, 50NFB, DREEP W34.9, GLAFAN, and highly transparent Glassine 40 all have non-penetration properties to liquids. Glassine 25.8 shows some non-penetration for medium chain fatty acid triglycerides, but thinks There should be no problem with taking paper as a plug-in. Since Glassine 25.8 shows penetration into water, water cannot be used as a solvent for perfume capsules. Glassine 40 has non-penetration to all liquids other than water.

(Example 3: Change in opacity of insert roll paper)

Evaluation method

In the present embodiment, the insert take-up paper used in Example 2 was overlapped with the transparent outer layer NatureFlex 23μ, and the change in opacity was evaluated by attaching a liquid. The liquid which was the same as the liquid used in Example 2 was dropped, and evaluated in the same manner as in Example 2.

The "change in opacity" was calculated from the difference between the opacity (%) after dropping the liquid and the opacity (%) before dropping the liquid. The related "appearance (transparency)" is evaluated together as shown in the following table.

As shown in Table 5, when the amount of change in opacity is 5% or more, the increase in transparency can be visually confirmed.

2. Evaluation results

The following shows the "change in opacity" and "evaluation" of various plug-in rolls.

The plain papers 24, N250, NPWS, P10000C, and P20000C all changed greatly in opacity after dropping the liquid, but according to the results of Example 2, these all showed transparency to liquids, and thus were not suitable as a card take-up paper.

NatureFlex 23μ does not show a change in opacity of more than 5%, so it is not suitable as a plug-in take-up paper.

Since 50NFB is opaque, the position of the fragrance capsule cannot be confirmed when the paper is used, and therefore it is not suitable as a card to take up the paper.

The opacity of DREEP W34.9 before dripping was 37.2%, and the amount of change in opacity of more than 5% was observed after dropping any liquid, and the increase in transparency was visually confirmed. In addition, DREEP W34.9 showed non-penetration to any liquid (see the results of Example 2). From this point of view, DREEP W34.9 can be used as a plug-in to take paper.

GLAFAN does not show a change in opacity of more than 5%, so it is not suitable as a plug-in take-up paper.

The opacity of Glassine 25.8 before dropping was 20.9%, and the amount of change in opacity of 5% or more after dropping the medium chain fatty acid triglyceride (MCT) and propylene glycol (PG), and visually confirming the increase in transparency. In addition, Glassine 25.8 showed non-penetration of the medium chain fatty acid triglyceride (MCT) and propylene glycol (PG) (see the results of Reference Example 2). From this point of view, when using these liquids as perfume-containing liquids, Glassine 25.8 can be used as a plug-in take-up paper.

The opacity of Glassine 40 before dripping was 31.2%, and the amount of change in opacity after 5% or more of the medium chain fatty acid triglyceride (MCT), propylene glycol (PG) and water was observed, and the increase in transparency was visually confirmed. . Further, Glassine 40 showed non-penetration of the medium chain fatty acid triglyceride (MCT), propylene glycol (PG), and water (the results of Reference Example 2). From this point of view, when these liquids are used as the fragrance-containing liquid, the Glassine 40 can be used as a card to take up the paper.

The high transparency Glassine 40 has an opacity of 16.2% before dripping. Further, after the medium chain fatty acid triglyceride (MCT) was dropped, the amount of change in opacity of 5% or more was observed, and the increase in transparency was visually confirmed. In addition, the highly transparent Glassine 40 shows impermeability to any liquid (see the results of Example 2). From this point of view, the highly transparent Glassine 40 can be used as a plug-in to take up paper.
