THE SCOPE OF THE INVENTION

The present invention relates to cigarette filter with capsule, located in the cavity where the capsule can be crushed fingers, and the cigarettes with filter that contains mentioned capsule.

THE LEVEL OF TECHNOLOGY

Cigarettes with filter that contains capsule, widely known where capsule is located in the cavity formed in cigarette filter. The cavity is formed, for example, between segments filter formed by separating filter. This cigarette filter that contains a capsule, made so that flavouring agent or adsorbent enclosed in a capsule, acted after crushing capsules while Smoking cigarettes. If the flavouring agent or adsorbent are fluid, after crushing capsules fingers, the liquid contained in the capsule, enters the tipping paper, which covered the cigarette filter. This raises the problem consists in the fact that the liquid contained in the capsule, sticks to the fingers that hold the paper, through which the attached filter. Another problem is that, if the liquid contained in the capsule, piercing to the wrapper, covering the fine-cut tobacco, Flammability cigarettes decreases. In addition, if the liquid contained in the capsule and penetrated wrap, lights up, it affects the taste and aroma of cigarettes.

Cigarette filter made, performing stage: wrap fiber filter in thin tissue paper and, thus, producing segment of the filter; and wrapping segment filter in the former paper (wrapping the entire each segment of the filter when using many segments of the filter, or wrap all segments of the filter together with capsules, if capsules are located in the cavities between segments of the filter). If forming paper made of impermeable material, for example, from malonarymka material, it is possible to prevent leakage of the fluid contained in the capsule, tipping paper. However, there is another problem, namely, that the liquid contained in the capsule, penetrates into thin paper, located on the inner side moulding of paper, and continues to penetrate to the wrapper.

The authors of the present invention conducted an analysis of the above-mentioned problems and replaced thin paper paper made of impermeable material, for example, malonervozan paper. The authors found that the liquid contained in the capsule, flows through the gap between the fine paper and forming paper, fine paper and fiber filter, and penetrates to the wrapper. In the subsequent analysis of the authors of the invention was used as a segment of the filter acetate fiber (NOAV), not wrapped in thin paper. Again the liquid contained in the capsule, flowed through the gap between NOAV filter and moulding of paper, and the leak was ended by the seepage of liquid to the wrapper. The authors of the invention, therefore, found that the above approach did not provide solutions to the problems.

In the Patent document 1 concerning the same problem, disclosed cigarette filter where capsule containing liquid material, placed between the segments of the filter. This cigarette filter contains the outer covering made from the material, which is virtually impermeable to liquid material enclosed in a capsule, and, thus, the capsule is covered in this outer covering. In short, to prevent seepage of liquid enclosed in a capsule, use impermeable materials (plastic, grades or virtually impermeable film or sheet). However, if the use of impermeable material referred to in the Patent document 1, there is a possibility of significant deterioration wrapper fiber filter and capsules. Since accepted that impermeable material referred to in the Patent document 1 is airtight, the material is not able to pass the air in cigarette filter to dilute the smoke. This can lead to a deficiency in the complication of firing essential part of cigarettes. One way to ensure drawing air in cigarette filter to dilute the smoke is the use of laser perforation. However, considering the problem of the welfare and security of the enterprise, laser, for example for punching cellophane, is not the preferred method.

There is another well-known cigarette filter containing capsule, in which the capsule sealed in fiber filter instead it was located in the cavity filter, the liquid contained in the capsule, adsorbirovanny fiber filter. When using such a cigarette a little more difficult to crush fingers capsule together with the fiber filter. It is also difficult to close up the capsule in a certain place fiber filter.

THE BEST METHOD OF PERFORMING THE INVENTION

As shown in figure 1, cigarette filter 1 according to the invention formed from: set (two in the drawing) filter materials 2 capsules 3, forming paper 4 and adhesive equipment 5. Filter materials posted 2 in line. Between filter materials 2 formed cavity 6, which is a capsule 3. In the capsule 3 contains flavouring agent or adsorbent in a liquid state. Flavouring substance can be, for example, aromatic chemical substance, for example, menthol or a similar substance. Adsorbent can be, for example, gidrotalzita or a similar substance. Capsule 3 is made, for example, of gelatin. At crushing capsules 3 flavouring agent or adsorbent, namely, the liquid contained in the capsule 3 is released. Filter materials 2 and capsule 3 wrapped in a sheet forming paper 4. Between filter materials 2 and forming paper 4 is located adhesive tool 5 for reliable bonding together of filter materials 2 and forming paper 4. Adhesive tool 5 described in more detail below.

Filter materials 2 contain fiber filter (harness), acting on its surface. More specifically, filter materials 2 manufactured by thermoforming fiber filter in the form of solid column without using thin paper. In short, filter materials 2 is made from NOAV mentioned above. Forming paper 4 contains impenetrable material to prevent seepage of liquid enclosed in a capsule 3. The way to ensure the forming of paper 4 material, preventing the infiltration described in more detail below.

By using the above configuration using moulding paper 4 prevent seepage of liquid enclosed in a capsule 3. In giving this configuration cigarette 7 filter containing capsule (see Figure 5), in the future, you can prevent the leakage of the fluid contained in the capsule, tipping paper 8 (see Figure 5). As adhesive agent 5 is located between the filtering materials 2 and forming paper 4, the liquid contained in the capsule 3, does not penetrate between the filtering materials 2 and forming paper 4. In giving this configuration cigarette 7 with a filter that contains the capsule, you can prevent seepage of liquid contained in the capsule, the wrapper tobacco 9-terminal (see Figure 5).

To reliably prevent leakage of the fluid contained in the capsule, through forming paper 4, forming paper 4 may be waterproof paper with water resistance, malonervozan paper, oil resistance, or water and malonervozan paper with water and oil resistance. That is forming paper 4 is made of impervious material with water and oil resistance. This method can be reliably prevented leakage of liquid, which is the liquid enclosed in a capsule 3, in the former paper 4. Another way is to modify the surface properties of moulding paper 4 to ensure oil - or water-resistance.

As shown in figure 2, material, preventing the infiltration may be wax 12 with water or oil resistance. In this case, the wax 12 put on the whole area, where forming paper 4 and filter materials 2 securely fasten together. During the wrap forming of paper 4 wax 12 melted. This method can be reliably prevented the infiltration of liquid enclosed in a capsule 3, in the former paper 4. Wax 12 can also be used as an adhesive funds 5 for gluing of filter materials 2 and forming paper 4 and, thus, prevent seepage of liquid contained in the capsule, between the filtering materials 2 and forming paper 4. When you do this through the use of an invention can be prevented in the future, when using cigarettes 7 filter that contains a capsule containing a liquid, not only seepage contained liquid in tipping paper 8, but also seepage her to wrap 10 of the tobacco rod 9. Using wax 12 increase efficiency, as with its help prevent and seepage of liquid contained in the capsule, through forming paper 4, and leakage of the fluid contained in the capsule, the vented from the interior moulding paper 4.

Another configuration adhesive funds 5 can be a layer to fill the gap that can be formed between the former paper 4 and filter materials 2, as shown in Figure 3. Layer to fill the gap formed in the area covering half or most of the circumference of filter materials 2, or preferably to the entire circumference of filter materials 2. Filter materials 2 and forming paper 4, thus securely fasten together with a layer to fill the gap that pass between them. These provide the ability reliable prevent oozing enclosed in a capsule 3, between filter materials 2 and forming paper 4. Wax 12 can be used as a layer to fill the gap. In this case, as a former paper 4 use of water and malonervozan paper, so as to prevent leakage of the fluid contained in the capsule, through forming paper 4.

As an adhesive tools you can use adhesive with the ability to grip. In this case, as shown in Figure 4, the adhesive is applied circles on adhesive side moulding paper 4. Filter materials 2 and capsule 3 move in the direction of the arrow D, before contact with former paper 4, and then wrap in forming paper 4. As the gap between the filtering materials 2 and forming paper 4 fill adhesive, filter materials 2 and forming paper 4 can be securely fastened together. These provide the ability reliable prevent oozing enclosed in a capsule 3, between filter materials 2 and forming paper 4. As adhesives, you can use glue, hot melt adhesive or a similar substance. In addition, adhesive does not necessarily apply circles.

Figure 5 presents schematically longitudinal section of cigarettes with filter that contains the capsule, which used cigarette filter described above. Cigarette 7 with a filter that contains the capsule formed from cigarette filter 1, tobacco rod 9 and tipping paper 8. The tobacco rod 9 and cigarette filter 7

together tipping paper 8, passing between them. Tipping paper 8 wrapped around the entire circumference of cigarette filter 1. At the same time, tipping paper 8 wrapped around the end portion of the tobacco rod 9 and, thus, it can help keep the filter. The tobacco rod 9 is formed from fine-cut tobacco 11 and wrappers 10, which is covered with fine-cut tobacco 11. You can prevent adhesion fluid enclosed in a capsule 3, to the fingers or seepage liquid to wrap 10 after crushing capsules 3, thus improving the quality cigarettes 7 filter containing capsule.

According to a comparative example 1, which used a commonly used moulding paper and fine paper, liquid contained in the capsule, penetrated forming the paper, after crushing capsules fingers. In the column "Trickle down to the tipping paper", comparative example 1,

thus, it means "Yes". In the column "Trickle down to the wrapper", line comparative example 1 also says "Yes", because the liquid contained in the capsule, penetrated between the former paper and fine paper. About seeped whether the liquid contained in the capsule, as a result of leakage, judged according to visual features (the same applies to the data, below). As shown in the comparative example 2, the paper used as moulding of paper, replaced malonervozan paper. As a result, due to properties malonervozan paper, was prevented leakage of the fluid contained in the capsule, through forming the paper. Hence, no leakage of the fluid contained in the capsule, tipping paper. On the other hand, was not prevented leakage of fluid contained in the capsule, forming between paper and fine paper, and the seepage inside of thin paper. The result in column "trickle down to the wrapper", thus, remains set to "Yes". As shown in the line "comparative example 3", thin paper also replaced malonervozan paper. Forming the paper was again malonervozan paper. However, there was a gap between the former and paper, thin paper, and the liquid contained in the capsule, penetrated through the gap. The result in column "trickle down to the wrap" was set to "Yes". To solve this problem, as shown in the comparative example 4, filter materials replaced by materials made from neobarocco acetate fibres (NOAV), and the thin paper is removed. Forming the paper was again malonervozan paper. However, the liquid contained in the capsule, penetrated through the gap between the forming paper and filter materials. The result in column "trickle down to the wrapper" preserved "Yes".

The authors of the invention then thought about applying wax on the forming of paper, and the melting result, as shown in an embodiment. Filter materials were again NOUV. Cigarette filter under variant of carrying out the invention of figure 2, used for the manufacture of cigarettes with filter containing capsule. After crushing capsules fingers seepage to tipping paper and wrap was prevented. The authors of the invention were achieved the same results in the above embodiment.
