Cigarette filter and capsule filter cigarette using the filter

The present invention relates to a cigarette filter having a capsule crushed by a finger in a cavity of a filter material, and a capsule filter cigarette using the filter.

There is known a capsule type filter cigarette in which a hollow is placed in a cigarette filter and a capsule is filled in the cavity. The void system divides, for example, the filter material and is disposed between the filter segments. The capsule type filter cigarette is obtained by crushing the capsule at the time of smoking to enclose the affixing agent or sorbent agent of the capsule. When the flavoring agent or the like is a liquid, there is a problem in that after the capsule is crushed by a finger, the content liquid is soaked to the tip paper of the cigarette filter, and the content liquid adheres to Hold the finger of the outer paper. Moreover, when the content liquid is saturated into the roll paper of the tobacco-coated tobacco, the combustibility of the cigarette is deteriorated. Further, when the content liquid soaked into the roll paper is burned, there is a problem that the flavor of the cigarette is affected.

The cigarette filter material is coated with the filter paper fiber to take up the filter material section, and then the filter material section is covered with the forming paper (when the filter material section is plural, all the filter material sections are covered, and when the cavity between the filter material sections has the capsule It is formed by coating all the filter media segments and capsules. By forming a forming paper using a permeation preventing material, for example, a material having oil resistance, it is possible to suppress the penetration of the content liquid into the outer layer paper. However, there is a problem that the content liquid is soaked into the take-up paper located inside the formed paper, and the content liquid is directly saturated to the roll paper.

The inventor of the present invention further reviewed and changed the take-up paper into a penetration preventing material such as oil-resistant paper. It is thus newly known that the contents are soaked between the take-up paper and the forming paper, or between the take-up paper and the filter material fibers to the roll paper. After further review, use N without a take-up paper W A (Non Wrapped Acetate) is used as a filter section. However, it was also confirmed in this case that the content liquid was soaked into the gap between the filter fibers of the NWA and the forming paper, and as a result, the content liquid was saturated to the roll paper, which was insufficient to completely solve the problem.

Reveal the same As a problem, Patent Document 1 discloses a cigarette filter in which a capsule containing a fluid material is placed in a region sandwiched by a filter member. The cigarette filter is substantially A material that is not permeable to the fluid material enclosed in the capsule forms an outer cover with which the capsule is covered. That is, in order to prevent the penetration of the content liquid in the capsule, a non-permeable material (cellulose, polyvinylidene chloride, or a film or sheet having substantially no permeability) is used. However, when the non-permeable material described in Patent Document 1 is used, it may adversely affect the coating operation of the filter fiber and the capsule. Further, since it is presumed that the non-permeable material described in Patent Document 1 is not gas permeable, the air for dilution cannot be incorporated into the cigarette filter. Therefore, it may be disadvantageous in the design of the product of the cigarette. On the other hand, it is also conceivable to use the laser perforation to pack the dilution air into the cigarette filter. However, the perforation of, for example, celluloid by laser is not ideal for safety and hygiene in the factory.

On the other hand, there is known a capsule-type filter cigarette which does not involve the capsule being filled into the filter fiber but is managed to cause the capsule content liquid to be absorbed by the filter fiber. In this case, not only is there some difficulty in crushing the capsule together with the filter fiber with a finger, but it is also difficult to embed the capsule in a specific portion of the filter fiber.

The present invention has been made in view of the above-mentioned conventional techniques, and an object of the present invention is to provide a cigarette filter material and a capsule type filter material cigarette using the filter material, which does not cause the capsule content liquid to permeate outside the cigarette filter material after crushing the capsule. In order to prevent the adhesion of the content liquid to the fingers or to wet the roll paper, the quality of the capsule type filter cigarette is improved.

In order to achieve the above object, the present invention provides a cigarette filter comprising: a plurality of filter materials arranged in a direction with a gap therebetween; a capsule disposed between the filter materials and sealed with a flavoring agent or a sorbent. a forming paper, which simultaneously covers the capsule and the plurality of filter materials, and connects the filter medium, and includes a permeation preventing material for preventing penetration of the content liquid; and a bonding means, each of the plurality of filter materials and the forming paper Between the filter media, a portion of the filter material is adhered to or partially adhered to the entire circumference; and the filter medium which is located closer to the tobacco rod side filled with the tobacco yarn than the capsule is the filter fiber. A non-packaged filter section that is exposed on the surface.

Further, the aforementioned forming paper is water-resistant paper having water resistance, oil-resistant paper having oil resistance, or water- and oil-resistant paper having water resistance and oil resistance.

The impregnation preventing material is a wax having water and oil resistance which is applied to the entire surface in close contact with the filter medium.

Further, the adhesion means is a gap-filling layer for filling between the formed paper and the non-packaged filter material section.

The aforementioned adhesion means is an adhesive having an adhesive property.

Furthermore, the present invention provides a capsule type filter material cigarette comprising the cigarette filter material of the invention and a tobacco rod connected to the cigarette filter material through the outer layer paper.

According to the present invention, since the formed paper prevents the penetration of the content liquid sealed in the capsule, it is possible to prevent the content liquid from oozing out to the outer layer paper when used as a capsule type filter cigarette in the future. Further, since the adhesive means is provided between the plurality of filter materials and the forming paper, the content liquid sealed in the capsule does not permeate between the filter medium and the forming paper. Therefore, when used as a capsule type filter cigarette in the future, it is possible to prevent the content liquid from oozing out to the roll of the tobacco rod.

Further, since the formed paper is water-resistant paper having water resistance, oil-resistant paper having oil resistance, or water- and oil-resistant paper having water resistance and oil resistance, it is possible to reliably prevent liquid permeation of the content liquid contained in the capsule. Therefore, when used as a capsule type filter cigarette in the future, it is possible to prevent the content liquid from oozing out to the outer layer paper.

Further, since the impregnation preventing material is a wax having water resistance and oil resistance which is applied to the entire surface in close contact with the filter material, it is possible to reliably prevent the liquid which is the content liquid enclosed in the capsule from penetrating the forming paper, and suppress the content liquid from flowing. The filter material is soaked between the forming paper and the forming paper. Therefore, when used as a capsule type filter cigarette in the future, it is possible to prevent the content liquid from oozing out to the outer layer paper, and also to prevent the content liquid from oozing out to the roll of the tobacco rod.

Further, since the adhesion means is a gap-filling layer for filling between the formed paper and the non-packaged filter material section, the non-packaged filter material section and the forming paper are surely adhered to each other through the gap-filling layer. Thereby, it is possible to surely prevent the content liquid sealed in the capsule from penetrating between the non-packaged filter material section and the forming paper. Therefore, when used as a capsule type filter cigarette in the future, it is possible to prevent the content liquid from oozing out to the roll of the tobacco rod.

Since the above-mentioned adhesion means is an adhesive having a bonding property, it is possible to fill the filter medium and the forming paper by an adhesive to make them adhere to each other. Thereby, it is possible to surely prevent the content liquid sealed in the capsule from penetrating between the filter medium and the forming paper. Therefore, when used as a capsule type filter cigarette in the future, it is possible to prevent the content liquid from oozing out to the roll of the tobacco rod.

Further, a capsule type filter cigarette having the effects of the present invention can also be obtained. Therefore, it is possible to prevent the content liquid sealed in the capsule after the capsule is crushed from adhering to the finger or soaking into the roll paper, thereby improving the quality of the capsule type filter material cigarette.

As shown in Fig. 1, the cigarette filter 1 of the present invention is formed of a plurality of (two in the figure) filter medium 2, a capsule 3, a forming paper 4, and a close contact means 5. The filter medium 2 is arranged in one direction across the interval. A cavity 6 is formed between the filter media 2, in which the capsule 6 is provided with a capsule 3. The capsule 3 is enclosed with an aroma or sorbent composed of a liquid. As the flavoring agent, there are, for example, spices such as menthol. As the sorbent, for example, hydrotalcite or the like is mentioned. The capsule 3 is formed of, for example, gelatin. Therefore, the flavoring agent or the sorbent as the content liquid is discharged by crushing the capsule 3. A plurality of filter media 2 and capsules 3 are covered by one sheet of forming paper 4. An adhesion means 5 for adhering the filter medium to the molded body is disposed between the filter medium 2 and the forming paper 4. A detailed description of the adhesion means 5 will be described later.

The filter medium 2 is exposed to the surface filter fiber (fiber bundle). Specifically, the filter fiber is heated and formed into a solid cylindrical shape without using a take-up paper. That is, it is the NWA described above. The forming paper 4 includes a penetration preventing material for preventing penetration of the content liquid sealed in the capsule 3. A detailed description of the manner of inclusion of the penetration preventing material will be described later.

According to the above configuration, the formed paper 4 prevents the penetration of the content liquid enclosed in the capsule 3, and therefore, when used as the capsule type filter cigarette 7 (see Fig. 5), it is possible to prevent the content liquid from oozing out to the outer layer paper 8 (refer to 5)). Further, since the adhesion means 5 is provided between the plurality of filter materials 2 and the forming paper 4, the content liquid sealed in the capsule 3 does not permeate from between the filter medium 2 and the forming paper 4. Therefore, when used as the capsule type filter cigarette 7 in the future, it is possible to prevent the content liquid from oozing out to the roll paper 10 of the tobacco rod 9 (see Fig. 5) (see Fig. 5).

In order to surely prevent the content liquid from penetrating through the forming paper 4, the forming paper 4 is a water-resistant paper which is resistant to water resistance, an oil-resistant paper having oil resistance, or a water- and oil-resistant paper having water and oil resistance. That is, a permeation preventing material having water resistance and oil resistance is used as the material of the forming paper 4 itself. Thereby, it is possible to reliably prevent the liquid belonging to the content liquid enclosed in the capsule 3 from penetrating the forming paper 4. Further, the forming paper 4 may be subjected to surface modification to impart oil resistance or water resistance.

Alternatively, as shown in Fig. 2, a wax 12 having water resistance or oil resistance can be used as the penetration preventing material. At this time, the wax 12 is applied to the entire surface in which the formed paper 4 and the filter medium 2 are in close contact with each other. Then, when the forming paper 4 is coated, the wax 12 is dissolved. Thereby, it is possible to reliably prevent the liquid belonging to the content liquid enclosed in the capsule 3 from penetrating the forming paper 4. Further, since the adhesion means 5 between the filter medium 2 and the forming paper 4 can be used, it is possible to suppress the content liquid from penetrating between the filter medium 2 and the forming paper 4. Therefore, when used as the capsule type filter cigarette 7 in the future, it is possible to prevent the content liquid from oozing out to the outer layer paper 8, and also to prevent the content liquid from oozing out to the roll paper 10 of the tobacco rod 9. When the wax 12 is used, it is possible to prevent the penetration of the content liquid through the forming paper 4 and the penetration of the content liquid along the inside of the forming paper 4, so that the efficiency is preferable.

As for the other adhesion means 5, as shown in FIG. 3, a gap-filling layer may be formed between the forming paper 4 and the filter medium 2. The gap-filling layer is formed in a range of more than half of the circumference of the filter medium 2, and preferably in the range of the entire circumference. Thereby, the filter medium 2 and the forming paper 4 pass through the gap-filling layer and are in close contact with each other. therefore. It is possible to surely prevent the content liquid enclosed in the capsule 3 from penetrating between the filter medium 2 and the forming paper 4. The wax 12 described above can also be used in the case of the gap-fill layer. In this case, paper having water resistance and oil resistance is used as the forming paper 4 to prevent penetration through the forming paper 4.

In addition, an adhesive having a bonding property can also be used as a bonding means. In this case, as shown in Fig. 4, the adhesive is drawn and applied to the succeeding surface side of the forming paper 4 in a spiral shape, and the filter medium 2 and the capsule 3 are moved in the direction of the arrow D to be contacted with the forming paper 4 to be wrapped. cover. Thereby, the filter medium 2 and the shaping paper 4 are filled with the adhesive agent, so that the filter medium 2 and the shaping paper 4 can be in close contact with each other. Therefore, it is possible to surely prevent the content liquid enclosed in the capsule 3 from penetrating between the filter medium 2 and the forming paper 4. As the adhesive, a paste or a hot sol or the like can be used. Further, the application of the adhesive is not limited to the spiral shape.

Fig. 5 is a schematic cross-sectional view showing a capsule type filter cigarette using the above cigarette filter. The capsule type filter cigarette 7 is composed of a cigarette filter 1, a tobacco rod 9, and an outer layer 8. The tobacco rod 9 and the cigarette filter 1 are connected through the outer layer paper 8. That is, the outer paper 8 coats the entire circumference of the cigarette filter 1 while covering the end of the tobacco rod 9 and holding it. The tobacco rod 9 is composed of a tobacco yarn 11 and a roll paper 10 covering the tobacco yarn 11. Thereby, it is possible to prevent the content liquid sealed in the capsule 3 after the capsule 3 is crushed from adhering to the finger or the paper 20, and the quality of the capsule type filter cigarette 7 can be improved.

In the above example, the filter medium 2 is described for all NWA, that is, the non-packaged filter material section that is not covered by the take-up paper, but as shown in FIG. 6 or FIG. The ordinary filter material section 2b covered by the take-up paper 13 which is usually used as a filter medium is used in combination. In this case, the non-packaged filter material section 2a may be located closer to the tobacco rod 9 side than the capsule 3. As described above, when at least the filter medium closer to the tobacco rod 9 side than the capsule 3 is used as the non-packaged filter material section 2a, the content liquid sealed in the capsule 3 can be prevented from adhering to the finger or penetrating into the roll paper 10. In the examples of Figs. 6 and 7, the three filter media of the common filter material section 2b and the non-packaged filter material section 2a are used. In Fig. 6, one unpackaged filter section 2a and two common filter sections 2b are used, and in Fig. 7, two unpackaged filter sections 2a and one common filter section 2b are used. The non-packaged filter material section 2a is disposed at a position closer to the tobacco rod 9 than the capsule 3. Further, the ordinary filter material section 2b may be any material such as a charcoal filter section as long as it is covered by the take-up paper 13.

Fig. 8 is an experimental example of the examples and comparative examples of the present invention.

First, in Comparative Example 1, when a user who is usually used as a forming paper and a take-up paper is used, since the content liquid permeates through the forming paper when the capsule is crushed by a finger, it may permeate into the outer layer paper. Further, since the content liquid penetrates between the forming paper and the take-up paper, there is a case where it is saturated with the roll paper. In addition, it is visually confirmed whether or not there is a bleeding of the content liquid due to the permeation (the same applies hereinafter). Therefore, as shown in Comparative Example 2, the formed paper was changed to oil-resistant paper. Thus, the content liquid is prevented from penetrating through the forming paper by the characteristics of the oil-resistant paper, and there is no possibility of permeating to the outer paper. However, it is not possible to prevent the content liquid from penetrating into the take-up paper along the forming paper and the take-up paper, and there is still a situation in which the paper is saturated. Therefore, as shown in Comparative Example 3, the take-up paper was also changed to oil-resistant paper. The forming paper is still oil resistant paper. However, there is still a gap between the forming paper and the take-up paper, and the content liquid will permeate along the gap, and there is still a situation in which the paper is saturated. Therefore, as shown in Comparative Example 4, the filter medium was set to NWA, and the take-up paper was removed. The forming paper is still oil resistant paper. However, the content liquid will permeate along the gap between the forming paper and the take-up paper, and there will still be a situation in which the paper is saturated.

To this end, a wax is applied to the forming paper as shown in the examples, and the wax is dissolved. The filter material is still NWA. That is, the cigarette-type filter material cigarette is manufactured by using the cigarette filter material of the embodiment of Fig. 2 described above, and when the capsule is crushed by the finger, the content liquid can be prevented from permeating to the outer layer paper, or being saturated with the roll paper, or soaked to the outer layer. Paper and roll paper. Further, in the embodiments of the invention described above, the same results can be obtained.
