Description

Technical Field

[0001] This invention belongs to the field of cigarette filter technology, specifically relating to a filter rod that can enhance the taste of cigarettes and its application. Background Technology

[0002] As the cigarette market grows and the number of cigarette consumers increases, consumers are also demanding higher standards for the taste and other aspects of cigarette products. To improve the smoking quality of cigarettes, manufacturers typically add flavoring, smoke-generating, and preservative-enhancing additives during the production process. These additives improve the taste and sensory quality of cigarettes.

[0003] CN115669999A discloses a method for preparing a sweet flavoring for cigarette tow and a cigarette filter rod. The method for preparing the sweet flavoring is as follows: (1) preparing a sweet component; (2) preparing a flavoring component; (3) mixing the sweet component, flavoring component, and solvent, and filtering out the sediment. The method for preparing the filter rod is as follows: (1) after the cigarette tow has been loosened, a plasticizer is added and coated; (2) the cigarette tow is fed into the forming cavity of the forming machine, and the sweet flavoring is added; wherein, the amount added to each filter rod is 8-80 microliters; (3) the cigarette tow is wrapped with forming paper and formed, the forming temperature is controlled at 60-80℃, and then cut to obtain the filter rod. The filter rod provided by this invention has a slow and continuous dissolution and release of flavoring, which improves the comfort of smoking cigarettes, greatly improves the richness and naturalness of the taste, and reduces the harm of cigarettes to human health.

[0004] CN117084448A discloses an agarwood cigarette and its manufacturing process. The manufacturing process includes: step (1), collecting agarwood leaves from agarwood trees; naturally drying the collected agarwood leaves for 2-5 hours; then drying the agarwood leaves with hot air for 4-6 hours to make the moisture content of the agarwood leaves 10-15%; step (2), cutting the dried agarwood leaves into shreds to obtain agarwood shreds; then sorting the agarwood shreds to remove leaf stems and impurities; step (3), mixing 5-10 parts of agarwood shreds from step (2) with 60-70 parts of tobacco shreds to obtain a first mixture; step (4), aging 1-2 parts of enhanced tobacco shreds. The biological agent is added to the first mixture in step (3), and after 6 hours of aging, it is dried to make the moisture content of the first mixture 7-9%; in step (5), 4-6 parts of tea leaves and 2-4 parts of licorice are dried with hot air, and then the dried tea leaves and licorice are ground into powder; in step (6), the first mixture in step (4) is mixed with the tea powder and licorice powder in step (5) to obtain the second mixture, and after 16-28 hours of moisture balancing, the moisture content of agarwood shreds, tobacco shreds, tea powder and licorice powder are made consistent; in step (7), the second mixture in step (6) is rolled into cigarettes using conventional cigarette rolling technology to obtain agarwood cigarettes. The agarwood cigarettes provided by this invention can enhance the flavoring, aroma enhancement and improve the quality of cigarette smoke, making the smoke sweet and mellow with a full aroma.

[0005] Most existing technologies enhance cigarette aroma and improve taste by adding flavorings during the filter rod or tobacco preparation process. However, when cigarettes produced by these processes are smoked, the tobacco is heated, resulting in high-temperature smoke that can cause the flavorings to decompose or volatilize, leading to a lack of distinct flavor. Therefore, to better enhance the consumer's sensory experience, there is an urgent need for a superior cigarette product to meet application requirements. Summary of the Invention

[0006] In view of the shortcomings of the prior art, the purpose of this invention is to provide a filter rod that can improve the taste of cigarettes and its application.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides a filter rod that can enhance the taste of cigarettes. The filter rod that can enhance the taste of cigarettes includes a filter core and a wrapping paper wrapped around the filter core. The wrapping paper is a double-layered splicing paper.

[0009] The outer tipping paper has an easy-tear strip that wraps around the circumference of the cigarette, and the easy-tear strip is serrated or wavy.

[0010] The inner layer of splicing paper has ventilation holes on its surface.

[0011] The filter rod provided by this invention can improve the taste of cigarettes. When in use, the easy-tear ribbon of the outer layer of the splicing paper can be torn off. Since the surface of the inner layer of the splicing paper has air holes, it can increase the inflow of outside air, thereby reducing the inhalation resistance of the cigarette, regulating the inlet temperature, and reducing the irritation of the smoke due to the dilution of air, thus improving the taste of the cigarette.

[0012] In addition, after the outer layer of the splicing paper is torn off, the filter rod provided by the present invention can have the remaining wavy or serrated splicing paper folded along the bottom line to form a petal-shaped appearance at a certain angle to the filter rod. This not only increases the playability of the cigarette, but also makes the cigarette less likely to roll and fall off.

[0013] Preferably, the inner and outer layers of splicing paper are glued together using an adhesive dotting method.

[0014] Preferably, the width of the tear strip is 0.5-2mm, for example, it can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm or 1.9mm, etc.

[0015] Preferably, the tear strip is wavy.

[0016] Preferably, the tear strip is a wavy semi-circular shape.

[0017] Preferably, the inner radius of the wavy semicircle is 1-5mm, for example, it can be 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, 4mm or 4.5mm, etc.

[0018] Preferably, one end of the tear strip has a raised tear head.

[0019] Preferably, the air vents on the inner layer of the tipping paper are arranged in a straight line along the axial direction of the cigarette filter rod, or arranged in a ring around the circumference.

[0020] Preferably, the vent holes on the inner tipping paper are arranged in a straight line along the axial direction of the cigarette filter rod;

[0021] Preferably, the radius of the vent hole is 0.5-0.8 mm, for example, it can be 0.55 mm, 0.6 mm, 0.65 mm, 0.7 mm or 0.75 mm.

[0022] Preferably, the straight line has 3-5 rows, for example, 3, 4 or 5 rows.

[0023] In this invention, by controlling the number of vent holes, the air permeability of the filter rod can be increased while making the inner layer of splicing paper easier to form. This can better reduce the irritation of the smoke and reduce the draw resistance of cigarettes.

[0024] Preferably, the air permeability of the inner splicing paper is 200-280 CU, for example, it can be 200 CU, 220 CU, 240 CU, 260 CU or 280 CU, etc.

[0025] Preferably, the outer surface of the inner tipping paper is coated with a fragrance layer.

[0026] As a preferred technical solution of the present invention, by coating the outer surface of the inner tipping paper with a fragrance layer, the cigarette can be made to have more aroma when smoked, improve the taste, and consumers can directly smell the aroma through the volatilization of the fragrance layer, making the cigarette have a refreshing effect.

[0027] Preferably, the thickness of the fragrance layer is 0.5-2mm, for example, it can be 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm, 1.1mm, 1.2mm, 1.3mm, 1.4mm, 1.5mm, 1.6mm, 1.7mm, 1.8mm or 1.9mm.

[0028] Preferably, the raw materials for preparing the fragrance layer include any one or a combination of at least two of the following: Peruvian extract, sweet orange extract, rose extract, violet extract, burley tobacco extract, peppermint extract, or green tea extract.

[0029] Preferably, the raw materials for preparing the fragrance layer are a combination of tobacco extract, sweet orange extract, peppermint extract and green tea extract.

[0030] This invention, through extensive experiments, has determined that the combination of tobacco extract, sweet orange extract, peppermint extract, and green tea extract to obtain a flavoring can better enhance the aroma components in tobacco leaves, enrich the aroma, and make the volatile aroma more comfortable for consumers, thereby improving the smoking quality of cigarettes.

[0031] Preferably, the mass ratio of the tobacco extract, sweet orange extract, peppermint extract and green tea extract is (2-4):(1-2):(1-2):(1-2).

[0032] Where “2-4” can be 2.1, 2.3, 2.5, 2.7, 2.9, 3, 3.1, 3.3, 3.5, 3.7 or 3.9, etc.;

[0033] The first "1-2" can be 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9, etc.;

[0034] The second "1-2" can be 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9, etc.;

[0035] The third "1-2" can be 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, or 1.9, etc.

[0036] Preferably, the filter element is made of cellulose acetate or polypropylene fiber.

[0037] Secondly, the present invention provides the application of a filter rod, as described in the first aspect, which can enhance the taste of cigarettes in the preparation of cigarettes.

[0038] Thirdly, the present invention provides a cigarette comprising a tobacco segment and a filter rod as described in the first aspect for enhancing the flavor of the cigarette.

[0039] All the specific point values ​​within the above range can be selected, and will not be elaborated on here.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] (1) The filter rod provided by the present invention can increase the taste of cigarettes. When in use, the easy-to-tear ribbon of the outer layer of the splicing paper can be torn off. Since the surface of the inner layer of the splicing paper is provided with air holes, the amount of outside air can be increased, thereby reducing the resistance of the cigarette and adjusting the inlet temperature. Furthermore, due to the dilution of the air, the irritation of the smoke can be reduced, thereby improving the taste of the cigarette.

[0042] (2) After the outer layer of the splicing paper is torn off, the filter rod provided by the present invention can be folded along the bottom line with the remaining wavy or serrated splicing paper to form a petal-shaped appearance at a certain angle to the filter rod. This not only increases the playability of the cigarette, but also makes the cigarette less likely to roll and fall. Attached Figure Description

[0090] The fragrance layer is prepared from a combination of Peruvian extract, sweet orange extract, peppermint extract and green tea extract in a mass ratio of 3:1:1:1.

[0091] Test Example 1: Detection of Flue Gas Composition and Temperature

[0092] Test cigarettes were made by processing the filter rods and tobacco shreds obtained from Examples 1-10 and Comparative Examples 1-2, which can improve the taste of cigarettes. Cigarettes made with ordinary filter rods (cellulose acetate filter core, wrapped with an ordinary tipping paper, with the same specifications and dimensions as in Example 1) were used as control cigarettes. Before the test, the easy-tear strip of the tipping paper on the outer layer of the test cigarette was torn off. Then, the wavy tipping paper left after tearing was folded up along the bottom line, so that the cigarette would form a petal shape with a certain angle to the tipping paper. Then, the inlet temperature of the mainstream smoke of the test cigarette after the above treatment was measured, and the draw resistance test was performed on the above cigarette.

[0093] Test method:

[0094] The draw resistance test was conducted in accordance with GB / T 22838.5-2009 Determination of Physical Properties of Cigarettes and Filters Part 5: Cigarette Draw Resistance and Filter Pressure Drop.

[0095] The smoke temperature test adopts the thermocouple temperature measurement method. The cigarette smoking model is simulated according to the national standard YC / T29-1996. The thermocouple is fixed 1 mm from the center of the cigarette filter outlet. The thermocouple is connected to the temperature data acquisition system to measure the temperature of the smoke at the cigarette filter outlet during smoking.

[0096] The results are shown in Table 1.

[0097] Table 1

[0098]

[0099]

[0100] As can be seen from the data in Table 1, the filter rods prepared in Examples 1-3 of the present invention, when used in cigarettes, can increase the inflow of outside air due to the air vents, thereby reducing the draw resistance of the cigarette and making the inlet temperature more suitable.

[0101] As can be seen from Examples 9-10, when the number of vents is small, the flow of outside air is not smooth, which increases the resistance of cigarettes and raises the inlet temperature. When the number of vents is large, the effect on the above effect is not obvious, and with too many vents, the inner layer splicing paper is more difficult to form.

[0102] As shown in Comparative Example 1, when the inner tipping paper has no air holes, the cigarette has a higher draw resistance and the inlet temperature is also unsuitable.

[0103] Test Example 2 Sensory Quality

[0104] Sample preparation was the same as in Test Example 1. Sensory quality tests were then conducted on the test cigarettes.

[0105] Test method: Refer to national standard GB 5606.4-2005 Cigarettes Part 4: Sensory technical requirements.

[0106] Testing criteria: Aroma scores range from 1 to 30 points, harmony scores range from 1 to 10 points, off-flavor scores range from 1 to 15 points, irritation scores range from 1 to 20 points, aftertaste scores range from 1 to 25 points, and the total score is 100 points.

[0107] The results are shown in Table 2.

[0108] Table 2

[0109]

[0110] As can be seen from Test Example 2, when the filter rods prepared in Examples 1-3 of the present invention are used in cigarettes, the cigarettes show significant improvements in aroma, off-flavors, harmony, irritation, and taste.

[0111] As can be seen from Example 4, coating with a flavoring layer can enhance the aroma and taste of cigarettes;

[0112] As can be seen from Examples 5-8, the selection of raw materials for the flavoring layer has a great influence on the aroma and taste of cigarettes, and the tobacco extract, sweet orange extract, peppermint extract and green tea extract have a synergistic effect in improving aroma and taste.

[0113] As can be seen from Examples 9 and 10, when the number of vents is small, the irritation and impurities of cigarettes will increase. When the number of vents is large, the reduction of irritation and impurities is not significant. Moreover, with too many vents, the inner layer of splicing paper is more difficult to form.

[0114] As can be seen from Comparative Example 1, when the inner tipping paper has no air holes, the cigarette is more irritating and has a poorer aroma and taste.

[0115] As shown in Comparative Example 2, when there is only an inner tipping paper, the flavoring components will evaporate due to the lack of protection from the outer tipping paper, thus affecting the taste of the cigarette.

[0116] The applicant declares that this invention illustrates a filter rod that can enhance the taste of cigarettes and its application through the above embodiments, but this invention is not limited to the above embodiments, that is, it does not mean that this invention must rely on the above embodiments to be implemented. Those skilled in the art should understand that any improvements to this invention, equivalent substitutions of the raw materials of this invention, additions of auxiliary components, and selection of specific methods, etc., all fall within the protection scope and disclosure scope of this invention.

[0117] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0118] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not describe the various possible combinations separately.
