Disclosure of invention

Technical problem

The objective of the invention is to provide a cigarette filter capable of uniformly transmitting to a smoker a plant's natural aroma from the first to the last puff when smoking, and cigarettes with such a filter.

Further, an object of the invention is to provide a cigarette filter providing an aromatherapy effect, such as overcoming a depressed state, preventing drowsiness, relieving stress, concentration, and reducing the inherent smell of a cigarette emanating from the smoker's mouth, while allowing the smoker to enjoy the aroma of plants when smoked.

Further, an object of the invention is to provide a cigarette filter, which causes the propagation and transfer of plant aroma through heat and steam generated by the combustion of a cigarette, without fear that the aroma will change under the influence of heat, due to the fact that the plant granules are added to the non-combustible part of the filter, not a tobacco column.

In addition, the object of the invention is the creation of a new cigarette filter and a cigarette with such a filter, which provide an aromatherapy effect and a filtering effect due to the plant by using the plant, and not the plant extract.

Technical solution

The present invention relates to a cigarette filter using a natural plant and to a cigarette with such a filter.

In particular, the present invention relates to a cigarette filter comprising one or more filter units, wherein any of the filter units is a plant aromatic filter unit containing only natural plant material.

Preferably, the plant aromatic filter unit is filled with plant material made from reconstituted tobacco leaf, filled with dried and then ground plant material, filled with plant granules using plant material, or in which plant material or plant granules, dried and then ground, are distributed on a filter made from fibrous material. A cigarette filter is made in any form selected from the group consisting of a double filter, a triple filter and a multi-part filter or a multifilter.

According to the invention, it is possible to transfer a fresh and clean aroma and reduce the bad taste that sometimes occurs when smoking, through the use of a vegetable aromatic filter unit containing plant material. In particular, since the plant material is produced in granular form, a weak plant aroma emits during storage and a strong plant aroma emits when the coating layers surrounding the granules melt or are removed by heat and steam when the tobacco column is burned and thermally decomposed during smoking.

Accordingly, since the natural plant aroma and the inherent taste of the cigarette are in good agreement with each other, according to the present invention, a pure natural aroma is stored and transmitted.

In the case where the cigarette filter is a double filter, it contains a conventional filter block of fibrous material and a plant aromatic filter block that is filled with plant material made in the form of a reconstituted tobacco sheet, filled with dried and then crushed plant material, filled with plant granules using plant material, or in which plant material or plant granules, dried and then ground, are distributed in a filter, ying of fibrous material.

In the case where the cigarette filter is a triple filter, it contains a conventional filtering unit made of fibrous material, a plant aromatic filtering unit, which is filled with plant material made in the form of a reconstituted tobacco sheet, filled with dried and then ground plant material, filled with plant granules using plant material, or in which plant material or plant granules, dried and then ground, are distributed in a filter the two- of fibrous material and a filter unit containing an absorbent or special filter unit.

In the case where the cigarette filter is a triple filter, it is preferable that it is a solid triple filter consisting of a conventional filtering unit of fibrous material, a vegetable aromatic filtering unit and a combination filter containing an absorbent or special filter (paper or containing cavities or the like. n.), since it is possible to smoke a cigarette in a situation where foreign substances are absorbed by the absorbent and removed.

In this context, an absorbent-containing filter block refers to a filter that is filled with absorbent material or in which the absorbent is uniformly distributed on the filter of fibrous material. Activated carbon or zeolite can be used as an absorbent in a non-limiting manner. Since the smoke is absorbed into the vegetable aroma filter after the harmful material is mainly filtered by absorbent material, this makes it possible to clean the smoke drawn in by the smoker.

The plant can be used without restriction if it is suitable for food. So, for example, one component or a mixture of at least two components selected from the group consisting of peppermint, curly mint, coffee, pineapple, chamomile, orange, eucalyptus, thyme, geranium, jasmine, rosemary, lavender, lemon sorghum, pine needles, clover, sage, taxol, bergamot, basil, valerian, hyssop, Chinese tea, myrrh and juniper. According to the invention, an extract or oil of a herbaceous plant is not used, and the plant is used by treating the foliage, stem, root or fruit of the plant itself.

The plant is dried in a shaded area to a moisture content of not more than 10% and then crushed to a certain size. When drying, a humectant is preferably added to provide softness while shaping the filter.

Reconstituted tobacco sheet can be obtained by extraction, cooking, cleaning and paper making, which is a common paper production process. These processes are well known, so no special description is required.

When grinding plant material to make a filter, it is usually ground or ground to a suitable size, which is 0.1-10 mm, preferably 0.15-5 mm, and even more preferably 0.1-5 mm. When filling the filter with only one crushed plant, it most preferably contains particles of at least 3 mm in a mass content of 50-75%, particles of 1.5-3 mm in a mass content of 15-32% and particles of 0.1-1, 5 mm in a mass content of 6-21%. Further, in the manufacture of a combined plant filter by distributing the crushed plant in a cellulose acetate filter, it is preferably crushed or ground to a size of 0.1-1 mm in a mass content of at least 80%.

Plant granules are obtained in the form of granules by dissolving in water an organic binder of the same type selected from the group consisting of a hydrophilic polymer, a hydrophobic polymer, a monosaccharide, a disaccharide, sugar alcohol, molasses and dextrin, distributing and coating with a dissolved organic binder a powder of dried and then ground plant material .

At the same time, plant granules contain a powder of plant material and an organic-based binder mixed in a weight ratio of 1-3: 1. In addition, an inorganic binder selected from the group consisting of silica, silicate and bentonite to the powder of the plant material is added to the plant granules in an amount of 1-30 wt.% To increase the ability of the powder to form.

Preferably, the plant granules have a size of 5-80 mesh.

The hydrophilic polymer is selected from the group consisting of polyethylene glycol, polyethylene oxide, gelatin, starch, dextran sulfate, sugar, carboxymethyl cellulose, chitosan, hydroxyethyl cellulose, hydroxymethyl cellulose, hydroxypropyl cellulose, methyl cellulose hydroxybutyric polyvinyl hydroxybutyric hydroxybutyric hydroxybutyric hydroxybutyric hydroxybutyric hydroxybutyric hydroxybutyric hydroxybutyric polyhydroxybutyric polyhydroxybutyric hydroxybenzoate from the group consisting of ethyl cellulose, high molecular weight methacrylic acid ester, polyethylene, polyamide, hydroxypropyl methyl cellulose phthalate, p oli (ethylene vinyl acetate), cellulose nitrate, silicone and a copolymer of lactide and glycolide, a monosaccharide selected from the group consisting of glucose, fructose, trehalose and galactose, a disaccharide selected from the group consisting of xylose, D-mannose, solbose, lactose and maltose, sugar alcohol selected from the group consisting of mannitol, sorbitol, xylitol, glycerin, erythritol and arabitol.

Plant material powder was obtained by drying a mixture of one or at least two components selected from the group consisting of peppermint, spearmint, coffee, pineapple, chamomile, orange, eucalyptus, thyme, geranium, jasmine, rosemary, lavender, lemon sorghum, pine needles, clover, sage, taxol, bergamot, basil, valerian, hyssop, Chinese tea, myrrh and juniper, at a temperature of 30-50 ° C for 10-20 hours and then grinding it to a size of 70-80 mesh.

The present invention extends to a cigarette with a cigarette filter according to any one of claims 1 to 12 of the claims.

Next will be described in detail examples of carrying out the invention with reference to the drawings. It goes without saying that the drawings are given as examples and are not restrictive, subject to various modifications. Hereinafter, a conventional acetate filter refers to a filter of fiber tows, or a filter of threads, or a fiber filter.

Next will be described in detail examples of carrying out the invention with reference to the drawings.

As shown in FIG. 1, a typical filter cigarette consists of a cigarette section 20 and a filter 10. The filter is classified as a monofilter, a double filter and a multi-part filter or a multifilter depending on the number of filter units.

Figure 1 depicts a double filter according to the invention in one embodiment. A conventional filter unit 11 is made of fibrous material, and a vegetable aromatic filter unit 12 contains plant materials of various types. This means that the vegetable aromatic filtering unit 12 can be filled only with plant materials prepared in the form of a reconstituted tobacco sheet, filled only with dried and then crushed plant materials, or filled only with plant granules. Alternatively, plant materials can be evenly distributed in the filter of fibrous material.

Figure 2 depicts a triple filter according to the invention in one embodiment. As shown in FIG. 2, a conventional filter unit 11, a vegetable aromatic filter unit 12, and a conventional filter unit 11 are connected to each other in the order shown.

Figure 3 depicts a triple filter according to the invention in another embodiment. As shown in FIG. 3, a conventional filter unit 11, a vegetable aromatic filter unit 12, and an absorbent filter unit 13 are connected to each other in the order shown. The absorbent filter unit 13 is filled only with absorbent material, or the absorbent is uniformly distributed in the filter material. In this case, it is preferable, but not limiting, to use an absorbent having an average size of 30-80 mesh with a specific surface area of 500-1500 m ² / g in terms of absorption intensity and pleasant taste. In this case, the absorbent-containing filter unit 13 is preferably located adjacent to the cigarette section 20.

Figure 4 depicts a triple filter according to the invention in the following exemplary embodiment. As shown in FIG. 4, a conventional filter unit 11, a vegetable aromatic filter unit 12, and a special filter unit 14 are connected to each other in the order shown. In this case, the special filter unit 14 is made in a special form, for example, in the form of a paper filter made by folding paper with the formation of a hollow space inside or the like. Preferably, a special filter unit 14 is located adjacent to the cigarette section 20.

5 depicts a quadruple filter according to the invention in one embodiment. As shown in FIG. 5, a conventional filtering unit 11, a vegetable aromatic filtering unit 12, containing an absorbent filtering unit 13 and a conventional filtering unit 11 are connected to each other in the order shown.

6 depicts a quadruple filter according to the invention in another embodiment. As shown in FIG. 6, a conventional filter unit 11, a vegetable aromatic filter unit 12, a special filter unit 14, and a conventional filter unit 11 are connected to each other in the order shown.

7 depicts a triple filter according to the invention in another embodiment. The triple filter consists of one conventional filter unit 11 and two plant aromatic filter units 12. One of the plant aroma filters consists of a filter unit 12a filled with plant granules 15, and the other consists of a filter unit 12b in which plant granules 15 are distributed on the filter. In this case, the filter unit 12b with the vegetable granules 15 distributed on the filter is preferably located adjacent to the cigarette section 20.

It should be noted that the described examples can be modified without any restrictions, provided that one or more filter blocks consist of a vegetable aromatic filter.

Next will be given a special description of the method of producing plant granules used in this invention. The method is performed in accordance with the diagram of Fig. 8.

First, one or more plant species, which should be the starting material for the plant granules, are mixed and then dried in step S1. In this case, the plants are dried at a temperature of 30-50 ° C for 10-20 hours. The dried plants are ground in step S2, and in step S3 only plant particles of 70-80 mesh size are sorted. At the same time, larger fractions that have not passed sorting are returned to the grinding stage. The plant powder sorted to 80 mesh is to be molded under pressure in step S4, and it is mixed with an organic binder or with organic and inorganic binders. At this stage, when molding under pressure, vegetable granules are obtained in the size range of 5-80 mesh. Subsequently, in step S5, the plant granules are dried, preferably at a temperature of 30-50 ° C. for 50-70 hours. The dried plant granules are sorted in step S6. Plant granules are sorted into two groups, in one group they have a size of 5-35 mesh, and in the other size of 35-80 mesh. Preferably, granules with a size of 5-35 mesh are used for a triple filter, and granules with a size of 35-80 mesh are used for a double filter, however this use is not restrictive.

Natural plant materials processed according to the invention are used after they are obtained in the form of plant granules, so that these materials can be used individually or in combinations, as far as they are permissible in accordance with the provisions of the law on food additives. In this case, one part containing the majority of plant components can be used in cigarette products, and the other part can be used in its natural state.

More specifically, you can use a mixture of two or more components selected from the group consisting of peppermint, spearmint, coffee, pineapple, chamomile, orange, eucalyptus, thyme, geranium, jasmine, rosemary, lavender, lemon sorghum, pine needles, clover , sage, taxol, bergamot, basil, valerian, hyssop, Chinese tea, myrrh and juniper.

More specifically, after collecting various types of plants to maintain their aroma at the best level, they are divided into foliage, stems, berries and root. You can use the part of the plant that contains more plant aroma, depending on the type of plant. At the same time, the collected plants must be dried in a shaded place, allowing free passage of air, or on a drying rack with an awning to protect from direct sunlight in order to prevent the loss of natural plant aroma.

After drying such materials to a suitable moisture content of 5-10%, foreign substances are sorted out of them and then coarsely grinding the materials to a size of 6 mesh. Then they are subjected to repeated grinding using a finger crusher to obtain fine particles up to 80 mesh in size. During this process, grinding is performed intermittently so that the temperature from friction in the crusher does not rise above 40 ° C. You can reduce the loss of plant aroma by repeating the grinding process lasting 1 minute with stops for 3 minutes several times to eliminate the temperature increase.

The invention is characterized by the process of imparting a spherical shape to said particles of a powder of plant material by creating a suspension of these powder particles in an aqueous solution and growing spherical particles from them. The plant powder must be obtained in the form of a powder up to 80 mesh in accordance with the conditions of the growth rate and the temperature level in relation to the granulation of spherical bodies when growing plant granules. Due to this, it is easy to control the size and distribution of particles and it is possible to obtain spherical plant granules with a size of 1-35 mesh, which is suitable for the manufacture of a cigarette filter. Although an inorganic binder, such as silica, silicate or bentonite, can be used in the solution of the invention to increase the ability of a natural plant powder to be molded, it is more preferable to dissolve a single organic binder in water selected from the group consisting of a hydrophilic polymer, a hydrophobic polymer, a monosaccharide , disaccharide, sugar alcohol, molasses and dextrin. In a more preferred way, the ability of spherical particles to be molded can be increased by using molasses or cellulose-based carboxymethyl cellulose in a 2% solution, which is an organic binder.

More specifically, a solution of carboxymethyl cellulose with a content of 0.5-2% and the crushed vegetable powder are passed through the nozzle to mix them in equal weight proportions, resulting in the formation of spherical plant granules with a size of 16-35 mesh. When using molasses, plant granules can be obtained by mixing molasses with water in a mass ratio of 1-5%. In addition to the agitator with plow blades used in accordance with the invention, an apparatus selected from the group consisting of a fluidized bed granulator, a pressure molding granulator, a disk granulator and a press granulator can be used.

A cigarette filter cigarette according to the invention is capable of delivering a natural plant aroma to a smoker that is not distorted by thermal decomposition or compound, to add a vegetable aroma to the filter by making it from granules, such as spherical bodies, and to evenly transmit the vegetable aroma from the first to the last puff when smoking.

In addition, the aromatic component of the cigarette is not transferred inside it to the next medium and does not evaporate even during the implementation during storage due to the fact that the vegetable granules are placed in the inner space of the filter, so that the vegetable aroma is constantly preserved.

After drying peppermint in the shade to a moisture content of not more than 10%, dried peppermint in the amount of 1000 g is sprayed as a moisturizer with a 3% aqueous solution obtained by dissolving glycerol in distilled water in a ratio of 10 ml / 100 g. Then, peppermint is crushed using a grinder to an average size of 1 mm. After this, curly mint is dried for 24 hours at normal temperature to obtain a final moisture content of 13%. Next, crushed mint curly is filled into the filter paper with the manufacture of a vegetable filter with a circumference of 24 mm, a length of 96 mm and a vegetation content of 10 mg / mm. The resulting filter has the following physical properties: weight - 1000 mg (including filter paper), hardness - 80% and suction resistance - 120 mm H ₂ O / 96 mm. Such a vegetable filter is divided into 8 identical parts to obtain a filter 12 mm long, which is combined with a cellulose acetate filter 15 mm long, thereby obtaining a double filter with a total length of 27 mm.

After making cigarettes by combining the prepared filter with a tobacco column, they are blindly tested by a group of 100 qualified experts. When testing, experts are allowed to evaluate based on a 10-point scale. The average values of the estimates are shown below in tables 1-3.

At the same time, using a combination of Burley leaf tobacco, Oriental type leaf tobacco and pipe-fired tobacco, tobacco is mixed in a mass ratio of 3: 2: 5, the mixture is sprayed as a humectant with a 3 wt.% Aqueous solution obtained by dissolving the humectant in distilled water, in a proportion of 10 ml / 100 g. Then the tobacco mixture is ground using a grinder to an average size of 0.9 mm The cigarette block is made on a cigarette machine by drying the crushed tobacco at a constant temperature to a final moisture content of 13%. The cigarette block has a circumference of 24.4 mm, a length of 57 mm, a tobacco weight of 600 mg, a absorption resistance of 45 mm H ₂ O / 57 mm and a hardness of 75%. Making a test image of a cigarette ends with attaching the column to the filter using mouthpiece paper.

The testing method is usually based on characters that mainly affect the smoker's preference for cigarettes. The following tables give the following definitions:

- Inherent flavor of a cigarette: refers to the inherent flavor of a tobacco sheet that a smoker can feel from a pipe-firing sheet, a Burley sheet and an oriental type sheet and means a quantitative sensation - the more intense it is, the closer the score is to 10 points.

- Odor of hay: refers to a smell that easily resembles the aromatic characteristic of a dried leaf (grass) - the more intense it is, the closer the score to 10 points.

- Sour smell: means stimulation in order to stimulate the nose and cause a sharp sensation the same as from the smell of acetic acid - the more intense it is, the closer the score to 10 points.

- Abnormal taste and smell: means an unpleasant odor that attracts attention as a characteristic that must be removed from the inherent taste and smell in a cigarette. This is an element that reduces the value of products - the more intense it is, the closer the score is to 10 points.

- Plant aroma: refers to the aroma of a natural plant component. The stronger the smoker feels a sweet aroma, less rejection, more purity and more freshness in the mouth and nose, the closer the score to 10 points.

- Feeling of restoration or reinforcement of strength: refers to the degree to which the internal cavity of the mouth and nose are adequately stimulated when smoking, while the smoker does not feel an aversion to the taste and aroma of the cigarette - the more intense it is, the closer the score is to 10 points.

- Cleanliness: it means a clean taste and is a concept opposite to the feeling of dirt, deposits in the mouth. Pure taste usually means good taste. The better the feeling of cleanliness, the closer the score to 10 points.

- Harmoniousness: it refers to the degree to which the aroma is inseparable, is not too intense or too weak and how the aromatic additive and the resulting smoke harmonize with each other. The better these characteristics are balanced, the closer the score is to 10 points.

- Preservation of plant aroma: this refers to the degree to which the plant aroma lasts from the first to the last puff when smoking. The longer the retention period, the closer the score to 10 points.

- Satisfaction from smoking: when determining the general subjective sensations when smoking or after smoking, the higher the degree of satisfaction from smoking, the closer the score to 10 points.

- Bad breath: this refers to the smell coming from the smoker after smoking. The more intense it is, the closer the score is to 10 points.

- Taste of bitterness: this refers to the typical taste of bitterness in the mouth felt like caffeine. It is usually felt from the inside of the tongue and persists for a long time. The more intense this sensation, the closer the score to 10 points.

- Stimulation: this refers to the feeling that a bad taste such as stench, pungent taste or the taste of smoke in the mouth, throat and nose lasts at least one second and slowly disappears after the smoker suddenly senses them. The more intense this sensation, the closer the score to 10 points.

- Clean aftertaste: means that there is no sensation of dispersed or adhering dust or greasy or oily contamination in the mouth - the less intense the sensation, the closer the score to 10 points.

- General satisfaction: in determining the general subjective sensations when smoking or after smoking. The higher the degree of satisfaction from smoking, the closer the score to 10 points.

In a general assessment of the taste of cigarettes, the use of a cigarette in accordance with the present invention showed excellent results in various evaluation characteristics, as shown in Tables 1, 2 and 3. In particular, it should be appreciated that the mouth odor is lower compared to using a conventional filter.

Further, it should be noted that the plant aroma, the feeling of restoration or strengthening of strength, and the aroma intensity are higher, and the plant aroma can persist from the first to the last puff compared to the case when the plants are added to tobacco. At the same time, comparative examples 1-4 show that the abnormal taste and smell are higher, the aftertaste is not good, and overall satisfaction is low compared to the present invention.

Further, in order to confirm that the plant component is transferred to the main flue stream, the following tests were carried out.

For filter cigarettes according to embodiments 1-4, mainstream smoke was collected by a Cambridge filter (circumference 44 mm) using an automatic smoking apparatus and removed at 30 ° C. for 30 minutes using a solid phase microextraction method (SPME, Supeico , 57344-U) for performing gas chromatographic analysis. The analysis conditions were as follows:

Carrier gas: nitrogen

Column: INNOWAX, J&W (length 60 mm × inner diameter 0.25 mm, film thickness 0.25 μm)

Detector: flame ionization detector (FID)

Inlet temperature: 250 ° C

Detector temperature: 230 ° С

Oven temperature: keeping at the initial temperature of 50 ° С for 3 minutes, increasing the temperature by 3 ° С per minute and then keeping at the temperature of 230 ° С for 20 minutes.

As a result of gas chromatography analysis, it was found that a peak that was not detected in a cigarette with a conventional filter was detected in a cigarette with a vegetable filter with a retention time of 56.787 minutes, and the main component of spearmint, called l - carvon, was transferred to the main smoke stream in the example one.

It was found that a peak that was not detected in a cigarette with a conventional filter was detected in a cigarette with a vegetable filter with a retention time of 52.511 minutes, and the main component of peppermint, the so-called l-menthol, was transferred to the main smoke stream in Example 2.

It was found that a peak that was not detected in a cigarette with a conventional filter was detected in a cigarette with a vegetable filter with a retention time of 56.787 minutes, and the main component of curly mint, the so-called l-carvone, was transferred to the main smoke stream in Example 3.

It was found that a peak that was not detected in a cigarette with a conventional filter was detected in a cigarette with a vegetable filter with a retention time of 56.787 minutes, and the main component of thyme, the so-called l-thymol, was transferred to the main smoke stream in Example 4.

Further, in order to measure the amount transmitted by the main smoke stream in accordance with the number of puffs of smoking, the results of transmission in accordance with the number of puffs and the content of the plant component in the quantity transferred are measured and are shown in Table 4 below.

Table 4 The content of the main component transmitted by smoke for the number of puffs The number of puffs when smoking SP 1 SP 2 SP 3 SP 4 l - carvon l - menthol l - carvon Thymol 2 puffs 0.1% 0.1% 0.1% 0.07% 4 puffs 0.1% 0.09% 0.09% 0.07% 6 puffs 0.11% 0.11% 0.11% 0.07% 8 puffs 0.11% 0.12% 0.13% 0.06%

As can be seen from table 4, in the cigarette according to the invention, the main component of the plant is transmitted in the same amount regardless of the number of puffs when smoking. Accordingly, when using the cigarette filter of the invention, it is possible to transfer the vegetable aroma evenly from the first to the last puff.

As described above, you can create a new aroma and taste by manufacturing a filter with natural herbaceous plants and the formation of a more saturated aroma when smoking, as well as significantly reduce the inherent cigarette smell and bad breath from a smoker's mouth. This reduces the aversion caused by the smell of the smoke stream along with the smell exhaled by the smoker.

In addition, the approval of a new generation can be met by products having such an aroma, which creates a trend of well-being and personal characteristics of consumers.

Further, since the material used to generate the aroma is not placed in tobacco, but in the filter, there is no burning of possible foreign materials in direct contact with the filter and there is no thermal decomposition or formation of compositions, so that no extraneous taste is created. Thus, the possibility of a normal sensation of a stable and continuous aroma of natural plants is provided.

Further, the invention is easy to put into practice, since the starting material of the plants described can be easily obtained, and the manufacturing method can be easily applied.
