Description

Cigarette filter and cigarette

The present invention relates to a filter for cigarettes containing a flavor capsule and a cigarette.

Conventionally, a flavor capsule is placed in a cigarette filter, and the flavor capsule is broken at the time of use to enjoy the flavor of the content liquid at the time of smoking, and the taste of the butt after the flameout is masked (Patent Documents 1 to 5) . Details of the flavor capsule are described, for example, in Patent Document 6. Filters for cigarettes containing such perfume capsules have various problems.

Fig. 1(a) shows a cigarette which is a chip paper 30 which is connected to a tobacco rod 10 and a filter 20 which is formed by wrapping a tobacco filler 11 with a roll paper 12, and The filter 20 is a filter plug 22 in which a fragrance capsule 21 is wrapped in a wound paper 23 . The fragrance capsule 21 has a structure in which the content liquid 21b is wrapped in the film 21a. When the cigarettes crush the film 21a of the fragrance capsule 21 during smoking, as shown in Fig. 1(b), the discharged content liquid 21b is absorbed by the filter plug 22 without oozing out to the outer paper 30. surface. However, when the fragrance capsule 21 embedded in the filter plug 22 is crushed, there is no feeling of touch, so that the feeling of use is poor.

Therefore, a plurality of filter plugs are separated from each other and disposed along the hollow portion, and a fragrance capsule is provided in the hollow portion. If the filter has such a configuration, the capsule is crushed when the capsule is crushed, so that the feeling of use is obtained. Preferably.

Fig. 2(a) shows a cigarette in which the outer layer paper 30 is connected to the tobacco rod 10 and the filter 20, and the tobacco rod 10 is formed by wrapping the cigarette filling 11 with the roll paper 12, and the filter 20 has The configuration of the fragrance capsule 21 is provided in the hollow portion between the two filter plugs 25. The raw paper 26 is wound around the two filter plugs 25, and the forming paper 27 is wound around the hollow portion so as to be separated from each other. Further, there is also a filter plug which lacks either or both of the raw material paper and the formed paper (the case of Fig. 1 is only a winding paper which also serves as a raw material paper and a forming paper). Since the usual forming paper is made of a material having high penetrability, if the cigarette 21 is crushed by the film 21a of the fragrance capsule 21 during smoking, as shown in Fig. 2(b), the discharged content liquid 21b will seep out. To the surface of the outer paper 30.

In order to suppress the bleeding of the content liquid to the surface of the outer layer, it is conceivable to use a non-liquid penetrating outer layer paper and/or a filter wrapper (raw material paper, forming paper, wound paper). These raw materials are not limited to paper, and may be cellophane, plastic wrap or composite materials thereof. When the forming paper 27 is made non-liquid penetrating, as shown in FIG. 2(c), the outflowing content liquid 21b is along the gap between the inside of the non-liquid penetrating forming paper 27 and the filter plug 25. Move toward the tobacco rod 10 and the mouth end. Then, finally, the tobacco filler 11 of the tobacco rod 10 is exuded to the roll paper 12 closer to the tobacco rod 10 side than the outer paper 30. In the direction of the mouth end, a situation occurs in which the end face of the filter plug 25 is oozing out along the gap between the inside of the forming paper 27 and the filter plug 25.

This problem can be prevented by applying a wax or a paste on the inner side of the non-liquid penetrating forming paper 27 to fill the gap between the inner side of the forming paper 27 and the filter plug 25, thereby preventing the content liquid 21b from flowing along the gap. flow. However, since the wax or the paste scale adheres to the filter manufacturing apparatus, mass production becomes difficult.

In the filter for cigarettes and the cigarette of the present invention, by adding a tackifier to the content liquid of the flavor capsule, the viscosity of the content liquid is 30 mPa ‧ s or more, thereby preventing the content liquid from oozing out to the surface of the outer paper and the tobacco rod during use. Roll paper and filter suction end face.

In the filter for cigarettes of the present invention, the content liquid of the flavor capsule provided in the hollow portion between the plurality of filter plugs contains a fragrance and a tackifier, and has a viscosity of 30 mPa ‧ (25 ° C) or more.

In the present invention, the viscosity of the content liquid is less than 30 mPa ‧ (25 ° C), especially when it is less than 18 mPa ‧ (25 ° C), when the flavor capsule is crushed, the content liquid will ooze out to the surface of the outer paper, the tobacco rod Roll paper and filter suction end face. The viscosity of the content liquid is preferably 30 mPa ‧ (25 ° C) or more, more preferably 80 mPa ‧ (25 ° C) or more.

In the present invention, for example, menthol, plant essential oil or the like can be used as the fragrance.

In the present invention, a liquid tackifier or a solid tackifier may be used as the tackifier added to the perfume capsule content liquid. As the liquid tackifier, a fat or oil such as tocopherol, rapeseed oil, olive oil, cottonseed oil, or sucrose diacetate hexaisobutyrate (SAIB) or the like can be used. More preferably, it is rapeseed oil or SAIB.

When fats and oils are used as the tackifier, it is preferably in the range of 19.1 to 57.4% by weight of the content liquid. When SAIB is used as the tackifier, it is preferably 40% by weight or more, more preferably 60% by weight or more based on the content liquid.

In the present invention, for example, a medium chain fatty acid triglyceride (MCT) can be used as a solvent for the fragrance and the tackifier contained in the content liquid.

(Example)

Embodiments of the invention are described below.

Fig. 3 is a perspective view showing the size of the filter for cigarettes produced in the present embodiment. Raw material paper (not shown) is wound around the two filter rods 25 on the tobacco rod side and the suction side of the acetate. The two filter rods 25 are separated from each other and disposed along the hollow portion, and a non-liquid penetrating (oil-resistant) forming paper 27 is wound around the two. A fragrance capsule 21 is disposed in a hollow portion between the two filter rods 25. The fragrance capsule 21 has a structure in which the content liquid 21b is wrapped in the film 21a. The length L1 of the filter rod 25 on the tobacco rod side is 11.0 mm, the length L2 of the filter rod 25 on the suction side is 10.0 mm, the length S of the hollow portion is 6.0 mm, the total length TL is 27.0 mm, and the diameter D of the fragrance capsule 21 It is 4.5mm. In the present invention, the content liquid 21b of the fragrance capsule 21 has a viscosity of 30 mPa ‧ or more.

The method for producing the flavor capsule is not particularly limited, and it is preferred to use a dropping method to produce a flavor capsule having a seamless film. In this method, a double nozzle is used, and by discharging the content liquid from the inner nozzle and discharging the liquid film material from the outer nozzle, the film liquid can be wrapped without a seam.

As shown in Fig. 4, in the filter for cigarettes of the present embodiment, since the viscosity of the content liquid 21b of the fragrance capsule 21 is 30 mPa ‧ (25 ° C) or more, when the film 21a of the fragrance capsule 21 is crushed, it can be suppressed. The discharged content liquid oozes out to the surface of the outer paper, the roll of the tobacco rod, and the end face of the filter suction port. In addition, it does not adversely affect the filter manufacturing apparatus.

example 1

It is prepared as a spice menthol and plant essential oil and as a solvent medium chain fatty acid triglyceride (MCT) (no tackifier), and mixed in the ratio of Samples A to C of Table 2 to prepare a content liquid of the flavor capsule. The viscosity of the content liquid was measured by a rotary viscometer (Tokyo Industry Co., Ltd. TVB-10M).

The starch, dextrin, and polysaccharide mixture as a coating material was mixed with 8% by weight or 20% by weight, and 92% by weight or 80% by weight of the above-mentioned content liquid, and a perfume capsule having a diameter of 4.5 mm was produced by a dropping method. Using the fragrance capsule, a cigarette filter as shown in Fig. 3 was produced, and the same cigarette as in Fig. 2(a) was produced.

Example 2

Prepared as a spice menthol and plant essential oil, as a solvent medium chain fatty acid triglyceride (MCT), and as a tackifier rapeseed oil, mixed in the ratio of Table 2 samples D to H to prepare a flavor capsule Content liquid. The viscosity of the content liquid was measured by a rotary viscometer (Tokyo Industry Co., Ltd. TVB-10M).

The starch, dextrin, and polysaccharide mixture as a coating material was mixed with 8% by weight or 20% by weight, and 92% by weight or 80% by weight of the above-mentioned content liquid, and a perfume capsule having a diameter of 4.5 mm was produced by a dropping method. Using the fragrance capsule, a cigarette filter as shown in Fig. 3 was produced, and the same cigarette as in Fig. 2(a) was produced.

Example 3

Prepared as a spice menthol and plant essential oil, as a solvent medium chain fatty acid triglyceride (MCT), and as a tackifier sucrose diacetate hexaisobutyrate (SAIB), as shown in Table 2, sample I The ratio of K is mixed to prepare the content liquid of the flavor capsule. The viscosity of the content liquid was measured by a rotary viscometer (Tokyo Industry Co., Ltd. TVB-10M).

20% by weight of a mixture of a starch, a dextrin and a polysaccharide as a coating material, and 80% by weight of the above-mentioned content liquid, and a perfume capsule having a diameter of 4.5 mm was produced by a dropping method. Using the fragrance capsule, a cigarette filter as shown in Fig. 3 was produced, and the same cigarette as in Fig. 2(a) was produced.

With respect to the cigarettes of the above samples A to K, the film of the fragrance capsule was crushed for 10 minutes, and then the content liquid was infiltrated to the surface of the outer layer paper, the roll of the tobacco rod, and the end face of the filter suction port. The results are shown in Table 2.

As is apparent from the results of Table 2, when the viscosity of the content liquid of the flavor capsule is 30 mPa ‧ (25 ° C) or more, the content liquid can be prevented from oozing out to the surface of the outer layer paper, the roll of the tobacco rod, and the end face of the filter suction port. Further, it is understood that when the viscosity of the content liquid of the flavor capsule is 80 mPa ‧ (25 ° C) or more, it is possible to more reliably suppress the bleeding of the content liquid to the surface of the outer layer paper, the roll of the tobacco rod, and the end face of the filter nozzle.

Example 4

In the experiments of the above Examples 1 to 3, it was investigated that the film of the perfume capsule was crushed, and within 10 minutes of the usual smoking time, the content liquid oozes out to the surface of the outer paper, the roll of the tobacco rod, and the end face of the filter suction port. . However, it is preferred that after the film of the flavor capsule is crushed, the content liquid does not ooze out to the roll of the tobacco rod after a long period of time. The case where the content liquid oozes after a long time is investigated in the following manner. Further, in the following experiment, the content liquid of the capsule did not contain a fragrance.

Sample L

The content of the capsule is only used as a solvent medium chain fatty acid triglyceride (MCT).

Sample M

The content of the capsule was prepared by mixing 43% by weight of a chain medium fatty acid triglyceride (MCT) and 57% by weight of rapeseed oil as a tackifier.

Sample N, O, P

60% by weight, 50% by weight or 40% by weight of the medium chain fatty acid triglyceride (MCT) as a solvent, and 40% by weight, 50% by weight or 60% by weight of SAIB as a tackifier to prepare a capsule The content of the liquid.

The viscosity of these contents was measured by a rotary viscometer (Dongji Industry Co., Ltd. TVB-10M). The composition and viscosity of the capsule content liquid are shown in Table 3.

The starch, dextrin, and polysaccharide mixture as a coating material was mixed at 20% by weight with 80% by weight of the above-mentioned content liquid, and a perfume capsule having a diameter of 4.5 mm was produced by a dropping method. Using the fragrance capsule, a cigarette filter as shown in Fig. 3 was produced, and the same cigarette as in Fig. 2(a) was produced.

With respect to the cigarettes of the above samples L to P, the film of the flavor capsule was crushed for one week, and then the content liquid was oozing out to the roll of the tobacco rod. At this time, the length of the content liquid oozing refers to the length measured from the end of the tobacco rod 10 connected to one of the filter plugs 25 to the position at which the content liquid oozes to the roll paper. The results are shown in Table 3.

Further, Fig. 5 is a graph showing the relationship between the viscosity of the content liquid of the samples M to P and the bleeding length of the content liquid.

As shown in Table 3, in the case of the sample L containing no tackifier, all of the 10 samples investigated had a leaching length of 57 mm after one week, and the content liquid reached the roll paper at the front end of the tobacco rod. In this case, when rapeseed oil or SAIB is used as the tackifier, even after one week, the content liquid does not reach the roll paper at the front end of the tobacco rod. Further, as is apparent from Tables 3 and 5, even if the viscosity of the content liquid is the same, the exudation length of the SAIB content liquid is shorter than that of the rapeseed oil.

When the exudation length of the content liquid is long, the components which are soaked in the contents of the roll paper are separated by a paper chromatography phenomenon. On the other hand, since the SAIB-containing content liquid as the tackifier has a short exudation length after one week, separation of the content liquid component due to the paper chromatography phenomenon can be suppressed.
