Description

Technical Field

[0001] The invention relates to the field of cigarette production, and in particular to a liquid flavor sealing tape, a preparation method and a heat-not-burn cigarette. Background Art

[0002] In recent years, heat-not-burn cigarettes have become more and more popular among consumers. Heat-not-burn cigarettes are a new type of tobacco product. Unlike ordinary cigarettes, heat-not-burn cigarettes are heated, while ordinary cigarettes are burned. Heat-not-burn cigarettes can make tobacco smell just right. When tobacco is not burned, the temperature of ordinary cigarettes is generally between 350℃ and 600℃. High-temperature burning of tobacco will bring a lot of harmful substances. Heat-not-burn cigarettes like this are generally heated below 300℃, and the harmful substances will be much less.

[0003] In the production process of heat-not-burn cigarettes, liquid flavors are added to thin tobacco slices. The liquid flavors for tobacco are blended from a variety of spices and have a certain aroma. When added to heat-not-burn cigarettes, they can enhance the flavor characteristics of the product, mask the miscellaneous smells, and bring out the aroma. This allows heat-not-burn cigarettes to have a unique aroma during storage and burning, allowing consumers to have completely different experiences when smoking different heat-not-burn cigarettes.

[0004] Therefore, in the field of heat-not-burn cigarette production, liquid tobacco flavor is an important raw material in cigarettes. In the prior art, liquid flavor is directly added to thin tobacco slices. During smoking, the thin tobacco slices will be quickly released after being heated. Generally, most of the flavor is released in the first five puffs. The designed number of puffs of heat-not-burn cigarettes is more than ten. As a result, consumers will feel a significant attenuation of the flavor after the first five puffs of the heat-not-burn cigarette.

[0005] In the prior art, there is also a production method that uses popping beads to add them to the mouthpiece of heat-not-burn cigarettes, but the popping bead adding process is relatively complicated, inefficient, and difficult to produce continuously at high speed. At the same time, the popping bead production process determines that the types of liquid flavors it carries are greatly limited, which is mainly related to the density of the flavor, and it is impossible to achieve a wide spectrum of flavor loading and addition. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a liquid flavor sealing tape for carrying liquid flavor, which is added to heat-not-burn cigarettes to prevent the rapid decay of the flavor of the heat-not-burn cigarettes during the smoking process.

[0007] Necessarily, the present invention also provides a method for preparing the above-mentioned liquid fragrance sealing tape.

[0038] The embodiments of the present invention are written in a progressive manner.

[0039] like Figure 1 and Figure 2 As shown, the present invention provides a liquid fragrance sealing tape 1, comprising three parallel layer structures, namely, a surface layer 101, a surface layer 2 103 and an inner layer 102;

[0040] The inner layer 102 is placed between the first surface layer 101 and the second surface layer 103 . The upper surface of the inner layer 102 is connected to the lower surface of the first surface layer 101 , and the lower surface of the inner layer 102 is connected to the upper surface of the second surface layer 103 .

[0041] Furthermore, at least one of the upper surface of the inner layer 102 and the lower surface of the surface layer 101 is an uneven surface, the upper surface of the inner layer 102 and the lower surface of the surface layer 101 are not completely in contact with each other, and there is a cavity channel running through from front to back between the upper surface of the inner layer 102 and the lower surface of the surface layer 101.

[0042] In the present invention, at least one of the lower surface of the inner layer 102 and the upper surface of the second surface layer 103 is an uneven surface, the lower surface of the inner layer 102 and the upper surface of the second surface layer 103 are not completely in contact with each other, and there is a cavity channel running through from front to back between the lower surface of the inner layer 102 and the upper surface of the second surface layer 103.

[0043] As an optional embodiment, the lower surface of the surface layer 101 of the present invention is a flat surface, and the upper surface of the inner layer 102 is provided with a battlement-shaped structure or a triangular sawtooth structure, such as Figure 1 or Figure 2 As shown, the lower surface of the surface layer 101 and the upper surface of the inner layer 102 have a battlement-shaped structure or a triangular sawtooth structure, forming a concave cavity channel that passes through from front to back and is used to carry liquid fragrance.

[0044] As an optional embodiment, the upper surface of the second surface layer 103 of the present invention is a flat surface, and the lower surface of the inner layer 102 is provided with a battlement-shaped structure or a triangular sawtooth structure, such as Figure 1 or Figure 2 As shown, the upper surface of the second surface layer 103 and the lower surface of the inner layer 102 have a battlement-shaped structure or a triangular sawtooth structure, forming a hollow channel that passes through from front to back and is used to carry liquid fragrance.

[0045] As an optional embodiment, the cavity channel between the lower surface of the inner layer 102 and the upper surface of the second surface layer 103 is filled with fragrance, and the cavity channel between the upper surface of the inner layer 102 and the lower surface of the first surface layer 101 is filled with fragrance.

[0046] The first surface layer 101 of the present invention is connected to the inner layer 102 by heat pressing, gluing or welding, and the second surface layer 103 of the present invention is connected to the inner layer 102 by heat pressing, gluing or welding.

[0047] The cross section of the liquid fragrance sealing tape 1 of the present invention is sealed by a sealing adhesive, which can prevent the fragrance from volatilizing and is more conducive to storage.

[0048] The surface layer 1 101 and the surface layer 2 103 of the present invention are film structures made of a combination of one or more materials such as PP, PE, PET, PLA, PCL, and PA; preferably, the material is liquefied within the heating temperature range of 60-130° C. for heat-not-burn cigarettes, so that when the heat-not-burn cigarettes are heated, the flavors in the liquid flavor sealing belt can be effectively released, maintaining a long-lasting flavor release of the cigarettes and improving the user experience.

[0049] The inner layer 102 of the present invention is a porous layer structure made of cellulose, carboxymethyl cellulose, polyvinyl acetate polymer, polyether or polylactic acid, which can better absorb liquid fragrance.

[0050] The liquid flavor sealing tape 1 of the present invention, when added to cigarettes, can prevent the rapid decay of the flavor of heat-not-burn cigarettes during the smoking process. At the same time, the liquid flavor sealing tape 1 of the present invention can load and add a wide spectrum of liquid flavors.

[0051] The present invention also provides a method for preparing the above-mentioned liquid fragrance sealing tape 1. The liquid fragrance sealing tape 1 of the present invention is produced using a sealing device, comprising the following steps:

[0052] Unwinding: Unwinding the surface layer 101, the inner layer 102 and the surface layer 2 103 in the unwinding device at the same time, and keeping the unwinding speed of the three coils synchronous;

[0053] Gathering: aligning the unrolled strips of the surface layer 101, the inner layer 102 and the surface layer 2 103 in parallel, and gathering and pasting them into prefabricated strips;

[0054] Lamination: The prefabricated strip is subjected to hot pressing, gluing or welding to obtain the liquid flavor sealing tape 1.

[0055] The step of loading spices is further included:

[0056] Infiltration: The cross section of the liquid fragrance sealing tape 1 is passed through the fragrance nozzle, and the liquid fragrance is filled in the cavity channel. The liquid fragrance contacts the inner layer 102, and the capillary action of the porous matrix causes the fragrance to be absorbed by the inner layer 102, thereby completing the loading of the fragrance in the blank sealing tape, and obtaining the fragrance sealing tape;

[0057] Sealing: Sealing the cross section of the liquid fragrance sealing tape 1 with a sealing adhesive can better prevent the volatilization of the fragrance in the sealing tape. If the loaded liquid fragrance is not highly volatile, the sealing step can also be omitted.

[0058] Cleaning and rolling up: Wipe off the excess fragrance on the surface of the fully sealed liquid fragrance sealing tape 1, roll it up and store it. During the infiltration process, the liquid fragrance inevitably remains on the surface of the liquid fragrance sealing tape. Wipe off the residual fragrance on the surface to facilitate the rolling up and storage of the liquid fragrance sealing tape, which is convenient for the next step of preparation.

[0059] The infiltration device used in the present invention includes a housing 201 and a nozzle 202. Figure 3As shown, the nozzle 202 is located at the bottom of the shell, and the fragrance 203 enters from the bottom of the nozzle 202 and is sprayed out from the top of the nozzle 202, forming a relatively stable fragrance protrusion at the top of the nozzle 202. The cross section of the liquid fragrance sealing belt 1 passes through the fragrance 203 protrusion at the top of the nozzle 202. The fragrance 203 is loaded in the inner layer 102 of the liquid fragrance sealing belt 1 due to capillary action, thereby realizing the loading of the fragrance 203.

[0060] The sealing step of the present invention can also use an infiltration device to replace the fragrance with a sealing glue, pass the cross section of the liquid fragrance sealing tape 1 through the top of the nozzle 202, and the sealing glue contacts the cross section of the liquid fragrance sealing tape 1, and completes the sealing after drying.

[0061] The present invention also provides a heat-not-burn cigarette. The liquid flavor sealing tape 1 loaded with flavors prepared by the present invention is added to the heat-not-burn cigarette, and can be added to tobacco shreds or to a filter structure. During the smoking process, the heat-not-burn cigarette is heated, so that the surface layer 101 and the surface layer 2 103 of the liquid flavor sealing tape 1 are liquefied, and the flavors are released.

[0062] The liquid flavor sealing tape prepared by the present invention is used to carry liquid flavors. When added to heat-not-burn cigarettes, the flavor of the heat-not-burn cigarettes can be prevented from rapidly decaying during the smoking process. Meanwhile, the liquid flavor sealing tape of the present invention can carry most of the flavors currently used in cigarette production.

[0063] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
