FIG. 1(a) shows a cigarette in which a tobacco rod 10 is connected to a filter 20 with a tipping paper 30, wherein the tobacco rod 10 is prepared by wrapping a tobacco filler 11 with a cigarette paper 12 and the filter 20 is prepared by wrapping a filter plug 22 having a flavor capsule 21 embedded therein with a plug wrapping paper 23. The flavor capsule 21 has a structure in which content liquid 21b is encapsulated with a shell 21a. When the shell 21a of the flavor capsule 21 is crushed in smoking of such a cigarette,
2 the content liquid 21b flowed out of the capsule is absorbed by the filter plug 22, and thus the fluid is not soaked through the tipping paper 30 to the surface thereof, as shown in FIG. 1(b). Good usability, however, is not obtained because the flavor capsule 21 embedded in the filter plug 22 does not give a sense that the capsule is crushed.
A filter having a structure in which filter plugs are separated from each other and arranged through a cavity, with a flavor capsule provided in the cavity, can give the sense that the flavor capsule is crushed, and thus has a good usability.
FIG. 2(a) shows a cigarette in which a tobacco rod 10 is connected to a filter 20 with a tipping paper 30, wherein the tobacco rod 10 is prepared by wrapping a tobacco filler 11 with a cigarette paper 12 and the filter 20 has a structure that a flavor capsule 21 is provided in a cavity between two filter plugs 25. A
material paper 26 is wrapped around each of the two filter plugs 25, and a shaping paper 27 is wrapped around the periphery where both plugs are separated from each other and arranged through the cavity. There is also a filter plug having either the material paper or the shaping paper, or having no material paper or shaping paper (in the case of FIG. 1, the plug has only the plug wrapping paper which serves as the material paper and the shaping paper).

There is also a filter plug having either the material paper or the shaping paper, or having no material paper or shaping paper (in the case of FIG. 1, the plug has only the plug wrapping paper which serves as the material paper and the shaping paper). When a shell 21a of the
3 flavor capsule 21 is crushed in smoking of such a cigarette, the content liquid 21b flowed out of the capsule is soaked through the tipping paper 30 to the surface thereof, as shown in FIG. 2B, because the shaping paper is generally made of a high-permeable material.
In order to suppress the soakage of the content liquid through the tipping paper to the surface thereof, it may be considered to use a liquid-impermeable tipping paper and/or filter wrapper (a material paper, a shaping paper or a plug wrapping paper). These materials are not limited to paper, and may be a wrapping material made of cellophane or plastic, or a composite material. When the shaping paper 27 is liquid-impermeable, the content liquid 21b flowed out of the capsule moves toward the tobacco rod 10 or the mouthpiece end along the gap between the inside of the liquid-impermeable shaping paper 27 and the filter plugs 25, as shown in FIG. 2(c). The liquid is finally passed through the tobacco filler 11 in the tobacco rod 10, and is soaked through the tipping paper to the cigarette paper 12 of the tobacco rod 10.
The liquid which moves toward the mouthpiece end along the gap between the inside of the shaping paper 27 and 25 the filter plug 25 is soaked to the end face of the filter plug 25.

The liquid which moves toward the mouthpiece end along the gap between the inside of the shaping paper 27 and 25 the filter plug 25 is soaked to the end face of the filter plug 25.
This disadvantage can be solved by coating the
4 inside of the liquid-impermeable shaping paper 27 with wax or paste to fill the gap between the inside of the shaping paper 27 and the filter plug 25, thereby preventing the migration of the content liquid 21b.
However, the residue of wax or paste adheres to a filter making machine, and thus it is difficult to perform mass production.

In the present invention, liquid thickeners and solid thickeners can be used as the thickener which is added to the content liquid in the flavor capsule. Fat and oil such as tocopherol, rapeseed oil, olive oil, cottonseed oil and sucrose diacetate hexaisobutyrate (SAIB) can be used as the liquid thickener. Of these, rapeseed oil and SAIB are more preferable.
When the fat and oil is used as the thickener, it is preferably used in an amount within a range of 19.1 to 57.4% by weight of the content liquid. When SAIB is used as the thickener, it is preferably used in an amount within a range of 40% by weight or more of the content liquid, preferably 60% by weight or more.
In the present invention, as a solvent for the
8 flavor and the thickener contained in the content liquid, for example, medium-chain fatty acid triglycerides (MCTs) can be used.
In the present invention, the content liquid may further contain other additives such as a solvent, a dye and an emulsifier.
In the present invention, the shell of the flavor capsule may be formed using, for example, starch, dextrin, polysaccharides, agar, gellan gum, gelatin, various natural gelling agents, glycerol, sorbitol, calcium chloride, or the like, and the shell may further contain a flavor and a coloring agent.
In the present invention, the tipping paper and/or filter wrapper (a material paper, a shaping paper or a plug wrapping paper) is liquid-impermeable, which means that they are oil-resistant. It is preferable to use an oilproof paper for the shaping paper 27, for example, of at least the tipping paper and/or the filter wrapper, which is directly brought into contact with the flavor capsule 21. Of the oilproof papers, for example, a oilproof paper manufactured by Nippon Paper Papylia Co., Ltd. is preferable, because it does not use a film or a fluorine-containing resin.
Properties of the oilproof paper manufactured by Nippon Paper Papylia Co., Ltd. are shown in Table 1.

In the present invention, the content liquid 21b in the flavor capsule 21 has a viscosity of 30 mPa=s or more.
The production method of the flavor capsule is not particularly limited, and it is preferable to use, for
10 example, a dropping method, because a flavor capsule having a seamless shell can be produced by this method.
According to this method, the content liquid and a liquid shell material are discharged at the same time from an inside nozzle and an outside nozzle respectively, using a double nozzle, whereby the content liquid can be encapsulated seamlessly with the shell liquid.
As shown in FIG. 4, the cigarette filter of this Example can suppress soakage of the content liquid 21b, which is flowed out by crushing the shell 21a of the flavor capsule 21, to the surface of the tipping paper, the cigarette paper of the tobacco rod, and the filter mouthpiece end face, because the content liquid 21b in the flavor capsule 21 has a viscosity of 30 mPa=s (25 C) or more. In addition, a filter making machine is not adversely affected.

Example 4 According to the tests of Examples 1 to 3, the soakage of the content liquid to the surface of the tipping paper, the cigarette paper of the tobacco rod 5 and the filter mouthpiece end face was checked within 10 minutes from the breakage of the shell of the flavor capsule, which was a usual smoking time. It is preferable, however, that only a small amount of the content liquid soaks to the cigarette paper of the 10 tobacco rod, even if a longer time elapses from the breakage of the shell of the flavor capsule. The soakage of the content liquid after a long time was checked as described below. In the following tests, the content liquid in the capsule did not contain any
15 flavor.
Sample L
Only medium-chain fatty acid triglyceride (MCT) as a solvent was used for a content liquid in a capsule.
Sample M
A content liquid in a capsule was prepared by mixing 43% by weight of medium-chain fatty acid triglyceride (MCT) as a solvent with 57% by weight of rapeseed oil as a thickener.
Samples N, 0 and P
A content liquid in a capsule was produced by mixing 60% by weight, 50% by weight or 40% by weight of medium-chain fatty acid triglyceride (MCT) as a solvent
Sample L
Only medium-chain fatty acid triglyceride (MCT) as a solvent was used for a content liquid in a capsule.
Sample M
A content liquid in a capsule was prepared by mixing 43% by weight of medium-chain fatty acid triglyceride (MCT) as a solvent with 57% by weight of rapeseed oil as a thickener.
Samples N, 0 and P
A content liquid in a capsule was produced by mixing 60% by weight, 50% by weight or 40% by weight of medium-chain fatty acid triglyceride (MCT) as a solvent
16 with 40% by weight, 50% by weight or 60% by weight of SAIB as a thickener.
The viscosity of the content liquid was measured by using a rotary viscometer (TVB-10M manufactured by Toki Sangyo Co., Ltd.). The composition and the viscosity of the content liquid in the capsule are shown in Table 3.
Twenty percent by weight of a mixture of starch, dextrin and polysaccharides as a shell material was mixed with 80% by weight of the content liquid described above to produce a capsule having a diameter of 4.5 mm by a dropping method. A cigarette filter shown in FIG. 3 was produced using the capsule, and further a cigarette similar to that shown in FIG. 2(a) was produced.
The shell of the flavor capsule of each cigarette of samples L to P was broken, and after one week, soakage of the content liquid to the cigarette paper of the tobacco rod was checked. In this case, the length of the content liquid soaked refers to a distance measured from the end of the tobacco rod 10 in contact with one filter plug 25, to a position in the cigarette paper to which the soaked content liquid reached. The results are also shown in Table 3.
FIG. 5 is a graph showing a relationship between the viscosity of the content liquid and the length of the content liquid soaked in samples M to P.

FIG. 5 is a graph showing a relationship between the viscosity of the content liquid and the length of the content liquid soaked in samples M to P.
17 As shown in Table 3, in the case of sample L
containing no thickener, the length of the content liquid soaked was 57 mm after one week, and the content liquid reached the cigarette paper at the tip end of the tobacco rod in all of the 10 cigarettes checked.
On the other hand, in the case where the rapeseed oil or SAIB was used as the thickener, the content liquid did not reach the cigarette paper at the tip end of the tobacco rod even after one week. In addition, it can be seen from Table 3 and FIG. 5 that the length of the content liquid soaked in the case where the rapeseed oil is used is shorter than that in the case where SAIB
is used, even if the content liquid has the same viscosity.
When the soakage length of the content liquid is large, a problem that components of the content liquid penetrating into the cigarette paper are separated by a paper chromatograph phenomenon may sometimes occur.
The content liquid containing SAIB as the thickener, however, can suppress the separation of the components of the content liquid, which is caused by the paper chromatograph phenomenon, even after one week, because the soakage length is small.
