The field of technology

The present invention relates to the field of cigarette technology, and in particular, it relates to a gel-coated thread from a paper base, a method for its production, and a cigarette containing such a gel-coated thread from a paper base.

Prerequisites of the invention

There are currently methods in the art of adding flavoring to a heatless cigarette that include adding a bursting cigarette ball to the filter rod, or adding a granular flavoring agent to the filter rod, or adding a cotton thread with an attached to it with a flavoring substance in the filter rod of a cigarette, etc., but these methods of adding flavor have their drawbacks. The addition of exploding balls to the filter rod is not only characterized by a relatively high cost of production, but also sets relatively high requirements for complex filter rod production technologies; adding a granular substance to the filter rod, which provides aroma, also challenges production technologies; and adding a cotton thread with a flavoring attached to the filter rod can often cause quality problems such as the cotton thread sticking out at the cut point, the filter rod bursting, etc.; however, the amount of attached flavoring in the method in which the flavoring is provided by means of a cotton thread is low, so it is released quickly, and the required flavoring cannot be effectively provided for a long time.

By inserting into a non-flammable heated cigarette an aromatic gel-coated filament, which is characterized by low cost, easy production, more attached substance, satisfactory substance release and long release duration, the present invention meets the requirements for adding various kinds of flavoring substances, smoke-forming substances to the cigarette etc. At the same time, by using the commonly accepted high-permeability wrapping paper and simple manufacturing technology, it is possible to obtain a gel-flavored filament characterized by a larger amount of attached substance, satisfactory release of substance and long-term preservation of aroma, to meet the requirements for adding various kinds of flavoring substances, smoke-generating substances to the cigarette

From substances, etc.

The essence of the invention

Based on the above problems, the purpose of this invention is to provide a gel-coated thread from a paper base, a method of its production, and a cigarette containing such a gel-coated thread from a paper base.

The task of this invention is solved by the implementation of the following technical solution: according to the first aspect of this invention, a gel-coated thread from a paper base is proposed, while the specified gel-coated thread from a paper base is obtained from a strip of a composite paper base by twisting; said composite paper base strip contains a gel layer carrying a functional material and a paper base layer.

Preferably, the diameter of the end surface of the indicated gel-coated thread from the paper base is 1-3 mm, and the degree of twist is 4-15 twists/m. At the same time, the degree of twisting is expressed by the number of turns of the aromatic thread 1 m long around its obi.

Preferably, the air permeability of the indicated layer of the paper base is 5000 СО-15000

Su, the density in grams is 25-40 g/m, and the width of the canvas is 20-60 mm.

Preferably, said gel layer carrying the functional material contains the functional material and the gel.

Preferably, this gel is polyethylene glycol.

Preferably, the indicated functional material contains at least one of the flavoring agent and the smoke-generating substance. At the same time, if the functional material is an aroma, then the gel carrying the functional material can also be called a gel that provides aroma.

According to the second aspect of this invention, a method of obtaining a gel-coated thread from a paper base is proposed according to the first aspect, while this method of obtaining includes the following stages, in which: (1) the substance in the form of a gel is heated to form a gelatinous mass; functional material is added, mixed and a gel bearing the functional material is obtained; (2) the paper base layer is subjected to embossing to obtain a paper base layer after embossing;

(3) the gel obtained in step (1) bearing the functional material is applied to the paper base layer obtained in step (2) after embossing; then cooled, folded and twisted to obtain a gel-coated thread from a paper base.

Preferably, the added amount of the specified functional material is from 5 95 to 60 95 of the weight of the specified substance in the form of a gel.

Preferably, when performing the embossing operation at stage (2), the distance between the two patterns is 1-5 mm.

Preferably, in step (3), the number of pleating levels is 2-5 levels, and the diameter of the pleats at each level gradually decreases, and their inner diameter in the pleating device of the last level is greater than the diameter of the specified gel-coated paper base thread by 0.2 -1 mm.

Preferably, in step (3), said pleat formation is a three-level pleat formation, with the diameter of the pleats at each level gradually decreasing, and their inner diameter in the pleat forming device of the last level being larger than the diameter of said gel-coated paper base thread by 0.2- 1 mm.

Preferably, the air permeability of the indicated layer of the paper base is 5000 SI-15000

SI, the density in grams is 25-40 g/m, and the width of the canvas is 20-60 mm.

Preferably, the indicated substance in the form of a gel is polyethylene glycol.

Preferably, the indicated functional material contains at least one of the flavoring agent and the smoke-generating substance. At the same time, if the functional material is an aroma, then the gel obtained in step (1) carrying the functional material can also be called the gel providing aroma, and the gel layer carrying the functional material can also be called the gel layer providing aroma.

According to a third aspect of the present invention, there is provided a cigarette comprising said gel-coated filament from a paper base according to the first aspect of the present invention.

Preferably, in one or more non-hollow areas of said cigarette, a gel-coated filament of a paper base according to the first aspect of the present invention is inserted.

The preferred number of gel-coated paper-based filaments inserted into each region of said cigarette is 1-3, wherein all of the gel-coated paper-based filaments are

Zo are located in the indicated cigarette with any positional distribution.

Preferably, the gel-coated filaments of the paper base contained in the same cigarette are the same or different.

The gel-coated thread from the paper base according to the present invention is characterized by the following advantages: 1. A large amount of substance that provides aroma. According to the design requirements of heatable non-flammable cigarettes, it is necessary to add substances that can be released in large quantities for a long time to provide the aroma in the filter rod, but in the existing aromas added to the cotton thread, the amount of the substance that provides the aroma, limited, and cigarette design requirements cannot be met.

In addition, there is a large amount of space between the fibers of the high permeability wrapping paper, and the high permeability wrapping paper, when used to produce a gel-coated thread of the same diameter as cotton thread, will contain more flavoring agent, while the amount of flavoring agent reaches a value that is 3 or more times larger than that of a cotton thread of a similar diameter, which can better meet the design requirements of non-flammable heated cigarettes. 2. Ensuring satisfactory aroma preservation. In existing technologies, when using a cotton thread to attach a flavoring agent, an already formed cotton thread is immersed in the flavoring agent (the structure of a simple cotton thread consists of many fibers twisted together, i.e. it is a multi-stranded cotton thread); because the set of fibers are tightly twisted with each other, the flavoring can gradually penetrate and reach the middle of the cotton thread only from the outer surface of the cotton thread, so the flavoring on the surface of the upper layer of the cotton thread is relatively more, and its amount will gradually decrease in the direction of the center of the thread, which leads to the fact that the cotton thread cannot carry the maximum amount of the substance attached to it, and the flavoring substance attached to the cotton thread evaporates even more easily, while the volume of evaporation of the flavoring substance increases with time. In contrast, when using highly permeable wrapping paper, such paper touches the flavoring agent in its unfolded state, and then, after uniform attachment of the flavoring agent throughout the entire thickness of the paper, is twisted to obtain a gel-coated thread from the paper base, which ensures the same amount of flavoring retained on its surface and inside her;

the flavor inside at room temperature does not evaporate easily and is not lost; in addition, during the heating process, the aroma can be effectively released due to the holes between the fibers. 3. Low cost and ease of implementation. The use of the above-mentioned cigarette paper makes it possible to implement a simple twisting technology with the provision of the possibility of obtaining the necessary gel-coated thread from the paper base, therefore, unlike the methods of adding aroma, which use bursting balls, this invention is characterized by a decrease in cost and ease of implementation.

The use of polyethylene glycol according to the present invention as a flavoring carrier is characterized by the following advantages: 1. Satisfactory stability: polyethylene glycol is characterized by relatively good stability, no color, no taste, no toxicity and no irritation; under normal conditions, it hardly reacts with other substances; thermal decomposition occurs only when its temperature reaches 300 "C, so in the case of adding a gel-coated filament from a paper base to a heated non-flammable cigarette, the temperature of the smoke will be much lower than 300 "0. 2. Satisfactory mutual miscibility: polyethylene glycol is characterized by satisfactory mutual miscibility with a number of organic substances and can be a solvent for water-based and oil-based flavorings used in cigarettes, so it can be used as a carrier for flavorings used in cigarettes. In addition, if the gel-like substance and the organic solvent are practically incompatible, then it cannot be used as a gel-carrier for flavoring. 3. Preservation of the aroma and good release of the substance: the molecular weight of polyethylene glycol is relatively high; at room temperature it is in a waxy solid state, therefore at room temperature the flavoring used in cigarettes is dissolved in it and does not evaporate easily and is not lost; in addition, in the process of smoking a cigarette, the smoke heats the gel, the polyethylene glycol melts, and the flavoring substances dissolved in it are released. 4. Satisfactory moisture retention: polyethylene glycol is characterized by excellent ability

To retain moisture, and the organoleptic qualities of the cigarette are effectively improved.

The production method according to the present invention is characterized by the following advantages: 1. According to the present invention, the paper base is pre-treated by embossing, which, on the one hand, contributes to a more uniform and reliable application of the gel carrying the functional material in larger quantities, and on the other side, helps to fold and twist the paper base, and also prevents the paper base from tearing. 2. According to the present invention, during the pleat formation operation, several levels of pleat formation are used, at which the diameter of the formed pleats gradually decreases, so it is possible to both cool the gel carrying the functional material on the paper base and form the paper base into pleats, which contributes to a more reliable attachment of the gel carrying the functional material to the paper base, while the gel will be difficult to squeeze out or fall off.

A cigarette containing such a gel-coated paper base filament according to the present invention is characterized by the following advantages: 1. The type, amount, and position of the gel-coated paper base filament inserted into the cigarette can be freely adjusted to enrich the flavor of the cigarette and meet the demands of smokers. regarding the variety of cigarette flavors. 2. Since the gel will melt and absorb heat during the smoking process, the added gel-coated thread will ensure a decrease in the temperature of the smoke.

Comparison of results:

On the basis of Table 1, it can be concluded that the amount of fragrance-providing substance per meter of gel-coated paper-based yarn is noticeably higher than in the case of cotton-flavoring yarn, that is, the amount of fragrance-providing substance on gel-coated yarn with there will be more of a paper base than on a cotton thread, which provides the aroma.

Option to implement Z

Testing the ability to retain aroma:

Using the gel-coated paper base thread according to embodiment 1 above and the flavoring cotton thread according to Comparative Example 1 respectively produced cigarettes of the same design, the only difference between which was that the gel-coated paper base thread was replaced on a cotton thread that provides aroma; both cigarettes were placed in an open environment with the same temperature and humidity conditions; on the same day, as well as on the 3rd and 10th days from the moment of receipt of cigarettes, respectively, an organoleptic evaluation was performed for both cigarettes; numbers from 1 to 10 determined the strength of the mint taste, while the higher the number, the stronger the mint taste; the taste of mint on the day of receipt of cigarettes was evaluated as equal to 10, which was used as the main criterion for its evaluation at other time periods. The results are presented in Table 2.

Table 2

Data of changes over time during the organoleptic evaluation of two cigarettes, cigarettes with foaming 1/7 | in the paper base "shetn i i 161" provides aroma

Comparison of results:

Based on Table 2, it can be concluded that in both cigarettes there is a downward trend in the weakening of the mint flavor over time, but in the cigarette with a cotton thread providing the flavor, the mint flavor is lost more quickly, to the point that in the later periods of taste there is no mint at all. Therefore, the gel-coated paper-based thread has a much better ability to retain the scent than the scent-providing cotton thread.

Implementation option 4

In a cigarette consisting of a tobacco section, a hollow filter rod section, a solid filter rod section A, and a solid filter rod section B, a gel-coated paper base filament is inserted in the centerline section of said tobacco section, as shown in FIG. 2.

Select a specially made cigarette paper 6000 SI, characterized by a density in grams of 35 g/m? and the width of the canvas is 30 mm, and subject it to embossing, while ensuring the distance between the two protruding patterns, which is 3 mm; rewound to obtain paper base 1 after embossing. At the same time, CO is a unit of measurement of the air permeability of cigarette paper, it is expressed as cm3/(cm min.) and denotes the air flow (in milliliters per minute, cm3/min.) of the tested sample passing through the surface with an area of 1 square centimeter under the conditions of the measured pressure, which is 1 kilopascal (kPa). 2. Heat 10 kg of polyethylene glycol in a water bath to 75 "C, wait for it to melt and become a gelatinous mass, add 2 kg of mint essence, stir for 10 minutes until evenly mixed with the formation of a gel that provides aroma. 3. The obtained in step (2) the gel that provides the aroma is placed in a water bath 2 for continuous heating, while the heating temperature is 75 °C. 4. The paper base 1 obtained in step (1) is unwound after embossing, while the unwinding speed is 8 m/min. It is fed in a horizontal direction to the gel application device, covered with a gel that provides aroma, and after applying the gel, it is moved to a distance 2 m, during which the paper base is cooled after applying the gel; after cooling, the gel-coated paper base is sequentially folded using device 4 for forming folds of the first level, device 5 for forming folds of the second level and device b for forming folds of the third level; then, with the help of the device 7 for twisting the thread by rotation at a twist rate of 7.67 twists/m, the gel-coated, providing aroma, the paper base must be twisted to obtain the molded gel-coated thread 9 from the paper base; finally, with the help of the winding device 8, the formed gel-coated thread 9 is wound from the paper base. At the same time, the inner diameter of the devices for forming folds of the first level, the second level, and the third level is 4 mm, 3 mm, and 2 mm, respectively.

Finally, the diameter of the resulting gel-coated paper-based filament is 1.637 mm and the degree of twist is 7.67 twist/m.
