Description

The utility model relates to the field of the tobacco industry and can be used to produce cigarettes with a filter equipped with a liquid capsule that can be destroyed from the outside.

A known capsule design for a cigarette filter [1], consisting of a sealed shell and a liquid core. It uses water as a liquid core, and the hermetic shell of the capsule is waterproof.

The disadvantage of this known device is that the forced destruction of a poorly extensible sealed shell from the outside is associated with a relatively uniform irrigation along the diameter of the cigarette filter with the liquid contents of the core.

The latter circumstance is the reason that the concentration of aromatic components in tobacco smoke is significantly reduced in the process of smoking a cigarette.

The closest in technical essence and the achieved result to the claimed device is the design of a capsule for a cigarette filter [2], made in the form of a sealed shell with liquid (water) enclosed in it. The water enclosed in a sealed enclosure is characterized by a pH in the range of 5.5 to 6.9, or in the range of 7.1 to 8.5. This technical solution was adopted as a prototype device.

The disadvantage of the prototype is that the forced destruction of a non-extensible (including brittle) hermetic casing from the outside is associated with a relatively uniform irrigation along the diameter of the cigarette filter with subshell contents, as a result of which the concentration of the aromatic component in the composition of tobacco smoke significantly decreases during cigarette smoking.

The technical result expected from the use of the proposed device is to reduce the decrease in the concentration of the flavoring component in the composition of tobacco smoke when smoking a cigarette with a filter equipped with a forcibly destructible capsule with liquid inside it.

The claimed technical result is achieved by the fact that the design of the capsule for the cigarette filter is made in the form of a sealed shell with a liquid enclosed in it, while an aromatic liquid is used as the liquid, and the shell is made of water-resistant material.

It is desirable that a water-soluble material be used as the water-resistant casing material.

It is preferable that the solution of the natural flavor or its oily extract be used as the aromatic liquid.

It matters that the solution of artificial flavoring or its oily extract be used as aromatic liquid.

It is convenient that as a water-soluble material of the shell was used material from the series: carrageenan, gelatin, pectin, agar-agar.

It matters that menthol be used as a flavor.

The claimed technical result is also achieved by the fact that the design of the capsule for a cigarette filter is made in the form of a sealed shell with a liquid enclosed in it, while a flavored liquid placed in nanocontainers is used as a liquid.

It is desirable that a solution of a natural flavoring agent or its oily extract be used as a flavored liquid.

Preferably, a solution of artificial flavoring or an oily extract thereof is used as the flavored liquid.

It matters that the material from the series: carrageenan, gelatin, pectin, agar-agar be used as the shell material.

It is advisable that menthol be used as a flavor.

The design of the claimed device is illustrated by a number of figures.

- figure 1 shows a conditional section of the proposed capsule for a cigarette filter (Figure 1-a proposed capsule is filled with liquid, Figure 1-b proposed capsule is filled with nanocontainers with liquid in them;

The capsule shell according to the first embodiment of claims 11 (FIG. 1-a), as well as to the second embodiment of claims 12 (FIG. 1-b) can be made of unstable (including water-soluble) material (for example, carrageenan, gelatin, pectin or agar-agar), wherein the capsule according to the first claim is filled with aromatic liquid in the free state 21 (Figure 1-a), and the capsule according to the second claim can be filled with aromatic liquid previously placed in nanocontainers 22 (Figure 1 b). An anhydrous solution of natural or artificial flavoring, or their oil extracts [3] can be used as an aromatic liquid, and the device disclosed in the information source [4] can be used as a nanocontainer.

Example 1

Use a spherical capsule 1 (Figure 2) with a diameter of 3.4 × 10 ^-3 m with a shell 11 (Figure 1-a) made of gelatin. The thickness of the mentioned gelatin shell was 95 × 10 ^-6 m. The capsule 1 (Figure 2) is filled with an oil extract of mint field, which in this example acts as an aromatic liquid in the free state 21 (Figure 1-a). Then, the capsule 1 (FIG. 2) is placed in the center of the tobacco filter 5 (FIG. 2) of the cigarette 3 (FIG. 2) equipped with a tobacco rod 4 (FIG. 2) made of pressed, crushed Virginia tobacco. The tobacco rod 4 (Figure 2) was enclosed in a tubular shell (not shown), which gives the cigarette 3 (Figure 2) the necessary mechanical strength, prevents arbitrary dispersion of shredded Virginia tobacco and ensures a stable rate of heat removal during smoking. As the material of the shell of the tobacco rod 4 (Figure 2) use, for example, smoking paper, preferably containing in a mass ratio of 10% -45% magnesium oxide and / or magnesium hydroxide, as well as flax, cellulose fiber and anti-ignition additives, such as citric acid potassium or potassium carbonate. Smoking paper by additional processing in an electrostatic field ("electrostatic perforation") acquires porosity in the range from 50 to 250 units. CORESTA. The density of the packing of the smoking material (crushed tobacco brand "Virginia") inside the tubular shell was 135 mg / cm ³ . The term "tubularity" by the applicant means a hollow product having a side wall and any desired section shape, in particular round, rectangular, polyhedral, oval or square. Tobacco filter 5 (Figure 2) is designed as a tubular porous filter, consisting of a porous element, which is a bundle of fibers of the filter material, and a casing of "fly-paper" (i.e. non-porous and hydrophobic) paper.

The tow of fibers of the porous material (in total 48000-50000 denier) form fibers (about 2.5-2.9 denier per thread), which can be formed from mineral, polymer or metal raw materials. However, it is preferable to use acetate fibers, acetate-cellulose fibers, cellulose fibers, lyocell fibers and fibers of thermoplastic, in particular polypropylene. In the present example, cellulose acetate fibers of 2.7 denier were used per thread of the total component in the tobacco filter 5 (FIG. 2) 50,000 denier. The used tobacco filter 5 (FIG. 2) may have mechanically perforated in its “mushroom” paper casing for air ventilation purposes (not shown). The latter serves to provide the so-called "air suction" or "air enrichment". The above-mentioned perforation of the “mushy” paper shell in this example provides 30% dilution of the stream of tobacco smoke, which is practically sucked into the mouth of the tobacco smoker when inhaling cigarette 3 (Figure 2), with a portion of fresh air that does not contain any components of tobacco smoke.

Before refueling a test batch of 100 cigarettes into a BORGWALDT KS Gmbh smoking machine, the mode of operation of this smoking machine is set. In particular, the frequency of smoking puff is set, namely: 3 puffs per minute, and the duration of smoking puff is set, namely: 5 sec. The duration of smoking is 6 minutes. At the same time, 4 smoking channels of the BORGWALDT KS Gmbh smoking machine are used on the measuring equipment (gas analyzer). 10 seconds before each batch of 4 cigarettes 3 (FIG. 2) is fed into the BORGWALDT KC Gmbh smoking machine, capsule 1 is depressurized (FIG. 2), previously placed in the tobacco filter 5 (FIG. 1), by simultaneous double-sided pressure with fingers hands on the positioning zone of said capsule 1 (Figure 2), i.e. in the first direction of the force acting by force F 6 (FIG. 2) and in the second direction of the force acting by force F 7 (FIG. 2). The magnitude of each of the effort F was about 90 grams. The destruction of the capsule 1 (FIG. 2) is accompanied by the impregnation of the surrounding fibers of the body of the tobacco filter 5 (FIG. 4) with the contents of the capsule, while the impregnation zone acquires a dumbbell shape, which is due, as the applicant believes, primarily to the elasticity of the shell 11 (FIG. 1-a), as well as the direction of application of force effects F 6 and 7 (Figure 2).

The concentration of the aromatic component in the stream of tobacco smoke during the “smoking” of a batch of 4 cigarettes with depressurized capsules 1 (Figure 2) by means of a BORG-WALDT KS Gmbh smoking machine was controlled by a MultiGsa Purity high-speed laboratory analyzer based on IF-Fourier spectrometry. The measurement results for 100 pieces of smoked cigarettes are presented in Figure 5 of curve 11. Curve 11 (Figure 5) shows the change in the relative concentration of flavoring component in tobacco smoke from the time of smoking cigarette 3 (Figure 2) after forced mechanical destruction of the claimed capsule 1 (Figure .2) for the case when the flavoring liquid was in a free state inside said capsule 1 (Figure 2).

Example 2

Use a spherical capsule 1 (Figure 2) with a diameter of 3.5 × 10 ^-3 m with a shell 12 (Figure 1-b) made of carrageenan. The thickness of the said shell was 108 × 10 ^-6 m. The capsule 1 (FIG. 2) was filled with nanocontainers [4], which contained an artificial flavor in the form of an ethyl vanillin solution, which in this example acts as an aromatic liquid placed in nanocontainers 22 (Figure 1-b). Then, the capsule 1 (FIG. 2) is introduced into the center of the tobacco filter 5 (FIG. 2) of the cigarette 3 (FIG. 2) equipped with a tobacco rod 4 (FIG. 2), which is made of pressed crushed Virginia tobacco. The tobacco rod 4 (Figure 2) was enclosed in a tubular shell (not shown), which gives the cigarette 3 (Figure 2) the necessary mechanical strength, prevents arbitrary dispersion of shredded Virginia tobacco and ensures a stable rate of heat removal during smoking. As the material of the shell of the tobacco rod 4 (Figure 2) can be used, in particular, smoking paper, preferably containing in a mass ratio of 10% -45% of magnesium oxide and / or magnesium hydroxide, as well as flax, cellulose fiber and flame retardants, such as potassium citrate or potassium carbonate. Smoking paper by additional processing in an electrostatic field ("electrostatic perforation") can acquire porosity in the range from 50 to 250 units. CORESTA. The density of the packing of the smoking material (ground Virginia tobacco) inside the tubular casing was in the present example 128 mg / cm ³ .

The term “tubularity” by the applicant, as in the previous example, means a hollow product having a side wall and any desired section shape, in particular round, rectangular, polyhedral, oval or square. Tobacco filter 5 (Figure 2) is designed as a tubular porous filter, consisting of a porous element, which is a bundle of fibers of the filter material, and a casing of "fly-paper" (i.e. non-porous and hydrophobic) paper.

The tow of fibers of the porous material in the tobacco filter 5 (Figure 2), as a rule (generally 48000-50000 denier) form fibers (about 2.5-2.9 denier per thread), which can be formed from mineral, polymer or metal raw materials. However, it is preferable to use acetate fibers, acetate-cellulose fibers, cellulose fibers, lyocell fibers and fibers of thermoplastic, in particular polypropylene. In the present example, polypropylene fibers of 2.6 denier were used per thread of the total component in the tobacco filter 5 (Figure 2) 49,000 denier. The used tobacco filter 5 (FIG. 2) may have mechanically perforated in its “mushroom” paper casing for air ventilation purposes (not shown). The latter (ie, perforation) serves to provide the so-called “air suction” or “air enrichment”. The above-mentioned perforation of the “mushy” paper shell in this example provides 30% dilution of the stream of tobacco smoke, which is practically sucked into the mouth of the tobacco when puffing with cigarette 3 (Figure 2), a portion of fresh air that does not contain any components of tobacco smoke.

Before refueling a test batch of 100 cigarettes into a BORGWALDT KS Gmbh smoking machine, the mode of operation of this smoking machine is set. In particular, the frequency of smoking puff is set, namely: 3 puffs per minute, and the duration of smoking puff is set, namely: 5 sec. The duration of smoking is 6 minutes. At the same time, 4 smoking channels of the BORGWALDT KS Gmbh smoking machine are used on the measuring equipment (gas analyzer). 10 seconds before each batch of 4 cigarettes 3 (FIG. 2) is fed into the BORGWALDT KC Gmbh smoking machine, the capsule 1 (FIG. 2), previously placed in the tobacco filter 5 (FIG. 1), is depressurized by simultaneous double-sided pressure hands on the positioning zone of said capsule 1 (Figure 2), i.e. in the first direction of the force acting by force F 6 (FIG. 2) and in the second direction of the force acting by force F 7 (FIG. 2). Moreover, the magnitude of each of the efforts F was about 93 grams. The destruction of the capsule 1 (FIG. 2) is accompanied by the filling of the surrounding interfiber space of the body of the tobacco filter 5 (FIG. 4) with the contents of the capsule, while the impregnation zone acquires a dumbbell-like shape, which is, as we believe, primarily due to the elasticity of the shell 12 (FIG. .1-b), as well as the direction of application of force effects F 6 and 7 (Figure 2).

The concentration of the aromatic component in the stream of tobacco smoke during the “smoking” of a batch of 4 cigarettes with depressurized capsules 1 (FIG. 2) by means of a BORGWALDT KS Gmbh smoking machine was controlled by a MultiGsa Purity high-speed laboratory analyzer based on IF-Fourier spectrometry. The measurement results for 100 smoked cigarettes are shown in Figure 5 of curve 12. Curve 12 (Figure 5) depicts the change in the relative concentration of flavoring component in tobacco smoke from the time of smoking cigarette 3 (Figure 2) after forced mechanical destruction of the claimed capsule 1 (Fig. 5). 2) for the case when a flavoring liquid is used, placed in nanocontainers.

Example 3

Use a spherical capsule 1 (Figure 2), the design of which corresponds to the design of the capsule of the prototype device. The diameter of the capsule 1 (Figure 2) is 3.4 × 10 ^-3 m, and the shell 11 (Figure 1-a) is made of ceramic (in particular, porcelain). The thickness of the said shell was 55 × 10 ^-6 m. The internal volume of the capsule 1 (FIG. 2) of the prototype device was filled with water with a certain pH. Then, the capsule 1 (FIG. 2) of the prototype device was introduced into the center of the tobacco filter 5 (FIG. 2) of the cigarette 3 (FIG. 2) equipped with a tobacco rod 4 (FIG. 2), which is made of pressed, crushed Virginia tobacco . The tobacco rod 4 (Figure 2) was enclosed in a tubular shell (not shown), which gives the cigarette 3 (Figure 2) the necessary mechanical strength, prevents arbitrary dispersion of shredded Virginia tobacco and ensures a stable rate of heat removal during smoking. As the material of the shell of the tobacco rod 4 (Figure 2) can be used, in particular, smoking paper, preferably containing in a mass ratio of 10% -45% of magnesium oxide and / or magnesium hydroxide, as well as flax, cellulose fiber and flame retardants, such as potassium citrate or potassium carbonate. Smoking paper by additional processing in an electrostatic field ("electrostatic perforation") can acquire porosity in the range from 50 to 250 units. CORESTA. The density of the packing of smoking material (ground Virginia tobacco) inside the tubular casing was 132 mg / cm ³ in the present example.

The term "tubularity" by the applicant, as in the previous two examples, means a hollow product having a side wall and any desired cross-sectional shape, in particular round, rectangular, multifaceted, oval or square. Tobacco filter 5 (Figure 2) is designed as a tubular porous filter, consisting of a porous element, which is a bundle of fibers of the filter material, and a casing of "fly-paper" (i.e. non-porous and hydrophobic) paper.

The tow of fibers of the porous material in the tobacco filter 5 (FIG. 2), as a rule (generally amounting to 48000-50000 denier) form fibers (about 2.5-2.9 denier per thread), which can be formed from mineral, polymer or metal raw materials. However, it is preferable to use acetate fibers, acetate-cellulose fibers, cellulose fibers, lyocell fibers and fibers of thermoplastic, in particular polypropylene. In the present example, polypropylene fibers of 2.5 denier were used per thread of the total component in the tobacco filter 5 (FIG. 2) 48500 denier. The used tobacco filter 5 (FIG. 2) may have mechanically perforated in its “mushroom” paper casing for air ventilation purposes (not shown). The latter (ie, perforation) serves to provide the so-called “air suction” or “air enrichment”. The above-mentioned perforation of the “mushy” paper shell in this example provides 30% dilution of the stream of tobacco smoke, which is practically sucked into the mouth of the tobacco smoker when inhaling cigarette 3 (Figure 2), with a portion of fresh air that does not contain any components of tobacco smoke. Before refueling a test batch of 100 cigarettes into a BORGWALDT KC Gmbh smoking machine (48 cigarettes have a liquid core formed by water with a pH of 6.0, and 52 cigarettes have a liquid core formed by water with a pH of 8.0), set the mode of operation of this smoking machine. In particular, the frequency of smoking puff is set, namely: 3 puffs per minute, and the duration of smoking puff is set, namely: 5.5 sec. The duration of smoking is 6 minutes. At the same time, 4 smoking channels of the BORGWALDT KS Gmbh smoking machine are used on the measuring equipment (gas analyzer). 10 seconds before each batch of 4 cigarettes 3 (FIG. 2) is fed into the BORGWALDT KC Gmbh smoking machine, the capsule 1 (FIG. 2), previously placed in the tobacco filter 5 (FIG. 1), is depressurized by simultaneous double-sided pressure hands on the positioning zone of said capsule 1 (Figure 2), i.e. in the first direction of the force acting by force F 6 (FIG. 2) and in the second direction of the force acting by force F 7 (FIG. 2). The magnitude of each of the efforts F was about 120 grams. The destruction of the brittle ceramic capsule 1 (Figure 2) is accompanied by the release of the contents of the said capsule into the surrounding space of the body of the tobacco filter 5 (Figure 4), while the impregnation zone acquires a rounded shape, which is, as we believe, primarily due to the fragility of the spherically made shell 12 (Figure 1-a). The concentration of the aromatic component (which was used anthracene) in the stream of tobacco smoke during the “smoking” of a batch of 4 cigarettes with sealed capsules 1 (Figure 2) by means of a BORGWALDT KS Gmbh smoking machine was controlled by a MultiGsa Purity high-speed laboratory analyzer, the operation of which is based on IF-Fourier spectrometry. The average measurement results for 100 smoked cigarettes using the capsule 1 (Fig. 2) of the prototype device are shown in Fig. 5 of curve 10. Curve 10 (Fig. 5) shows the change in the relative concentration of flavoring components in tobacco smoke from the time of smoking of the cigarette after forced mechanical destruction of the prototype capsule. As follows from the experimentally obtained data presented graphically in Figure 5, in the proposed device according to the first embodiment, the change in the relative concentration of flavoring component in tobacco smoke during smoking of cigarette 11 (Figure 5) after more than two forced mechanical destruction of the claimed capsule times less than when using the prototype device. It should be noted that a comparison of curves 10 and 12 (Figure 5) suggests that a change in the relative concentration of flavoring component in tobacco smoke during smoking of a cigarette after forced mechanical destruction of the claimed capsule for the case when the flavoring liquid was placed in nanocontainers (second embodiment) three times less than when using the prototype device.

Therefore, the above comparative (with the prototype device) experimental data is guaranteed (at times) confirm the achievement of the claimed technical result when using the claimed device in both variants of the embodiment, which the applicant sees in reducing the decrease in the concentration of flavoring components in the composition of tobacco smoke when smoking a filter cigarette, equipped with a forcefully destructible capsule with a liquid-containing core inside it.

For the manufacture of the claimed device in both variants, without exception, technologies and materials known from the prior art can be used, which, as the applicant believes, allows him to consider the utility model claimed by him as being compatible with the patentability condition of utility models “industrial applicability”.
