Description

[Technical Field]

[0001] The present invention relates to the field of non-combustion heated tobacco products, and in particular to non-combustion heated tobacco products cases. [Background technology]

[0002] In recent years, non-combustion heated tobacco has emerged in the tobacco industry, and its production scale, technological innovation level, and market share have continuously expanded and improved. Non-combustion heated tobacco shares the characteristics of both electronic cigarettes and cigarettes, and uses an electric heater to heat the tobacco substance, but at a temperature significantly lower than the ignition point of tobacco leaves, resulting in smoke that retains the distinctive tobacco aroma but is less toxic.

[0003] Currently, commercially available non-combustible heated tobacco products can be broadly divided into two types. One type is modeled after the structure of a paper cigarette, with tobacco leaves wrapped in cigarette paper and tipping paper, but the wrapping structure is weak and prone to breakage, with open ends, prone to moisture imbalance, and a short shelf life. The other type uses a paper tube as a wrapping case, wrapped in tipping paper on the outside, has a strong structure, and has a sealed end at the end, which reduces contact of the tobacco leaves with air, slows moisture loss, and has a long shelf life.

[0004] In the two conventional non-combustion heated tobacco products, the tobacco substance comes into direct contact with the breathable, flammable paper material, which can easily cause moisture in the tobacco to permeate through the paper and evaporate to the outside, potentially affecting the effectiveness of the tobacco. Furthermore, when the tobacco is heated, the innermost paper layer that comes into direct contact with the tobacco leaves is prone to burning and a burnt smell often results.

[0005] In the field of conventional paper-wrapped cigarettes, regarding the wrapping paper, a method of applying a ceramic coating to the surface of the wrapping paper and using the obtained ceramic-coated wrapping paper as a liner for the tobacco case has been technically mature and widely adopted. Also, in existing patented technologies, for the purpose of optimizing the quality of smoke using ceramic particles, a mixture of ceramic particles and a binder has been proposed to be applied as a coating layer on the surface of the rolling paper, or a ceramic rolling paper is manufactured by a papermaking process. However, it is targeted at conventional combustion-type paper-wrapped cigarettes. In order to achieve flammability and ashing properties, it is necessary to add a combustion promoter to compensate for the "drawback" of the non-flammability of ceramics, which results in an expensive and complex process, so its market penetration is limited due to its technical drawbacks.

[0006] In response to the above problems, as a result of repeated research by the inventor of this patent to delay the loss of moisture in the tobacco and maintain the stability of the internal components of the tobacco, it has been discovered that the ceramic film in the coating technology can effectively achieve the stabilization of components and long-term sustainable moisture retention inside the tobacco. Although the coating technology can use a clay film, a ceramic film, a silicon crystal film, etc., as a result of further repeated tests and research by the inventor, it has been found that the raw materials used in the clay coating technology are the easiest to handle, the manufacturing process is the simplest, and the clay coating has the strongest compatibility with different use environments.

Summary of the Invention

Problems to be Solved by the Invention

[0007] In order to solve the problems in the above-mentioned prior art, the present invention aims to provide a case of a non-combustion heated cigarette that can significantly improve the stability of components and greatly improve the wettability of tobacco substances in a non-combustion heated cigarette by directly applying a ceramic film to the tobacco packaging layer that is in direct contact with the tobacco leaves so as to solve the above-mentioned defects existing in the winding technology of non-combustion heated cigarettes in the prior art.

Means for Solving the Problems

[0008] According to one aspect of the present invention, there is provided a case for a non-combustion heated ceramic cigarette, which includes a main body pipe, a sticker located at one end of the pipe, and a filter located at the other end of the pipe, and a ceramic film is provided in a contact layer with tobacco leaves in the pipe. Preferably, a ceramic film is provided on the contact surface between the sticker and the tobacco leaves.

[0009] Preferably, the ceramic film sticker is a double-sided laminated paper, that is, a ceramic film is provided on one surface, and a water barrier film is provided on the other surface. More preferably, the water barrier film is an aluminum film. Preferably, the grammage of the ceramic film of the pipe and the ceramic film of the sticker is 2 to 10 gsm. Preferably, a tip paper is provided on the outer surface of the pipe provided with the ceramic film. Preferably, the grammage of the ceramic film of the sticker is greater than the grammage of the ceramic film of the pipe. Preferably, the pipe is a paper tube formed by spirally winding multi-layer paper or a paper tube formed by straight winding wide-width paper.

[0010] Preferably, the paper for pipe manufacturing has a smooth surface on one side and a rough surface with a predetermined roughness on the other side, and the ceramic film is provided on the rough surface of the paper with roughness. The ceramic film sticker has a smooth surface on one side and a rough surface with a predetermined roughness on the other side, and the ceramic film is provided on the rough surface of the paper with roughness. If a water barrier film is further provided on the ceramic film sticker, the water barrier film can be provided on the smooth surface.

[0011] Preferably, a plurality of through holes are formed in the sticker. Since the air permeability is good, there is no significant sense of resistance and smooth suction can be performed, the through hole ratio is 4% or more. According to the inventor's research, it is more preferable that the through hole ratio is 12.6%. This through hole ratio is particularly preferable in terms of improving air permeability and suction smoothness. Here, the through hole ratio is the ratio of the total area of the through holes to the inner diameter circular area of the pipe end face. Also, the aperture of the through hole is preferably 0.2 mm, and the center distance of the holes is preferably 0.5 mm.

[0012] Preferably, the ceramic film is a clay film, a ceramic film, a silicon crystal film or a similar material film, and its color is preferably milky white. More preferably, the ceramic film is a clay film.

[0013] Preferably, the ceramic film paper tube is manufactured by winding a combination of 65 gsm paper for the ceramic film paper tube, 120 gsm and 60 gsm paper for the paper tube. The ceramic film sealing paper is manufactured from a 77 gsm laminated paper obtained by coating a ceramic film on the rough surface of a 70 gsm base paper and an aluminum film on the smooth surface, and the laminated paper is uniformly perforated with holes having a pore diameter of 0.20 mm, a hole center distance of 0.50 mm, and a through-hole ratio of 12.6%. With the above configuration, the present invention has the following features.

[0014] 1. The non-combustion heating type ceramic film cigarette case of the present invention can maintain the wetting effect of cigarettes for a long time and balance the active substances. During the process of forming a coating on the ceramic film by coating technology, the surface of the film becomes a porous structure, which contributes to the stability adjustment of each component inside the cigarette case and the mitigation of volatilization and deterioration.

[0015] 2. The non-combustion heating type ceramic film cigarette case of the present invention has flame retardancy and heat insulation properties. The high temperature resistance of the ceramic film can effectively block heat, concentrate the heat of the heating substance in the pipe, and more effectively achieve heating. Furthermore, the outer layer paper of the pipe is not affected by high temperature and does not burn, preventing burns to the human body and being safer.

[0016] 3. The case of the non-combustion heated ceramic membrane tobacco of the present invention can prevent the odor from the pipe under high temperature environment. In the field of non-combustion heated tobacco, the heating temperature is generally 280 - 480 °C. In this high temperature environment, a paper tube without a ceramic membrane is likely to have a phenomenon of nicotine residue on the inner wall, generating the smell of burnt paper, which may affect the taste when inhaled together with the smell of smoke, causing discomfort. In contrast, the ceramic membrane pipe using a ceramic membrane can greatly improve the high temperature resistance, thus effectively avoiding the occurrence of the above situation, that is, effectively avoiding the generation of odor and ensuring the purity of the smoke.

[0017] 4. The case of the non-combustion heated ceramic membrane tobacco of the present invention is provided with a ceramic membrane on the paper for manufacturing the ceramic membrane pipe, so the mechanical strength of the paper can be greatly improved, thereby significantly improving the mechanical strength and firmness of the tobacco case. Since the density of the ceramic membrane is much higher than that of the paper, the strength of the paper provided with the ceramic membrane is also much higher than that of the original paper, being flexible and not easily damaged, not easily becoming soft and wrinkled, convenient for cutting and winding, useful for storage, transportation, and equipment use, making it more convenient for use in production operations. Also, it can greatly improve the hardness of the tobacco case, make the tobacco structure more stable, and prevent it from being easily bent or deformed.

[0018] 5. The particularly preferred clay film of the present invention is that in the coating process, various clay powders are mixed with resin, uniformly coated on the surface of the paper, and after drying, the moisture evaporates to form a dry clay film on the surface of the paper. Therefore, the formed clay film has a porous membrane structure and has very excellent moisture retention. Also, since the clay contains a lot of silicon crystals, the clay film has excellent high temperature resistance, heat insulation, and flame retardancy.

[0019] 6. The case of the non-combustion heated ceramic membrane tobacco of the present invention can be applied to a wide range of non-combustion heated tobacco products, and can be applied to tobacco pellets, tobacco sheets, tobacco leaf groups, or other tobaccos and their derivative products. 7. The material for manufacturing the ceramic membrane is of natural origin, environmentally friendly, and a renewable resource.

[0020] 8. Reduce costs. By adopting ceramic coating technology, the amount of paper used in the cigarette case can be significantly reduced, making it more economical and meeting the requirements of sustainable development.

Embodiments for Carrying Out the Invention

[0021] Example 1 A case for non-combustion heated cigarettes, manufactured from a ceramic membrane paper tube, ceramic membrane sealing paper located at one end of the pipe, and a filter located at the other end of the pipe.

[0022] Among them, the above-mentioned ceramic membrane paper tube was manufactured in the following way. First, a ceramic membrane was coated on the rough surface of 60 gsm paper for manufacturing paper tubes to produce 65 gsm paper for ceramic membrane paper tubes. Then, this paper for ceramic membrane paper tubes was used as the innermost layer of the cigarette case, and it was wound in combination with 120 gsm paper for paper tubes and 60 gsm paper for paper tubes to manufacture a ceramic membrane paper tube. Among them, the ceramic membrane of the paper for ceramic membrane paper tubes was in contact with the loaded tobacco leaves.

[0023] The above-mentioned ceramic membrane sealing paper was manufactured in the following way. First, a ceramic membrane was coated on the rough surface of 70 gsm base paper, and an aluminum membrane was coated on the smooth surface to obtain 77 gsm laminated paper. Then, holes with a pore diameter of 0.20 mm, a hole center distance of 0.50 mm, and a through-hole ratio of 12.6% were evenly formed in the laminated paper by infrared laser drilling technology to form a ceramic membrane sealing paper. The ceramic membrane sealing paper manufactured in this way had excellent air permeability of through-holes to ensure smooth suction and no significant sense of resistance. The case for non-combustion heated cigarettes manufactured by the method of Example 1 has the following advantages.

[0024] In the case of the ceramic membrane paper tube, firstly, since it is made of three layers of paper for the paper tube (i.e., 65 gsm ceramic membrane paper for the paper tube, 120 gsm and 60 gsm paper for the paper tube), the ceramic membrane paper tube has a uniform thickness and high mechanical strength, and is not easily bent, which is advantageous for the mechanized production of cigarettes and their subsequent use. Secondly, since the ceramic membrane paper for the paper tube is coated with a +5 gsm grade ceramic clay film, it can significantly and continuously maintain the wetting effect of cigarettes, balance the active substances, contribute to the stability adjustment of each component inside the cigarette case, and can greatly alleviate volatilization and deterioration. Thirdly, through the combination of three layers of paper for the paper tube (i.e., 65 gsm ceramic membrane paper for the paper tube, 120 gsm and 60 gsm paper for the paper tube), the appropriate thickness of the non-combustion heated cigarette case is achieved, which is neither too thin nor too soft, helps the pipe maintain its shape without being easily bent or damaged, and the hand will not get hot, and furthermore, the thickness is not too thick to cause high costs.

[0025] In the case of the ceramic membrane sealing paper, firstly, a +7 gsm grade ceramic clay film thicker than the +5 gsm grade ceramic clay film coated on the ceramic membrane paper for the paper tube is used, so that the wetting effect can be further improved, and the volatilization and deterioration of the tobacco substances loaded in the non-combustion heated cigarette case can be more effectively prevented. Secondly, the 77 gsm laminated paper has an ideal thickness, which can prevent the ceramic membrane sealing paper from being too thick for the smooth insertion of the insert heater, and can also prevent the ceramic membrane sealing paper from being too thin and being damaged by external forces. Thirdly, an appropriate through-hole ratio is selected to ensure not only ideal air permeability but also prevent the tobacco substances in the non-combustion heated cigarette case from leaking, and ensure smooth suction of the whole pipe, making it comfortable to use. Fourthly, the hole punching method adopts laser punching, which enables high-speed and uniform processing compared with mechanical punching and has no waste processing scraps. Example 2 A non-combustion heated cigarette case made of a ceramic membrane paper tube, a ceramic membrane sealing paper located at one end of the pipe, and a filter located at the other end of the pipe.

[0026] Among them, the above-mentioned ceramic film paper tube was manufactured by the following method. First, a ceramic film was coated on the rough surface of 120 gsm paper for manufacturing paper tubes to produce 122 gsm paper for ceramic film paper tubes. Then, this paper for ceramic film paper tubes was used as the innermost layer of the cigarette case and wound in combination with 120 gsm paper for paper tubes to manufacture a ceramic film paper tube. In the case of the ceramic film sealing paper, its manufacturing method is as follows. That is, a ceramic film was coated on the rough surface of 80 gsm base paper, and an aluminum film was coated on the smooth surface to obtain 85 gsm ceramic film sealing paper. Uniform holes with a pore diameter of 0.20 mm, a hole center distance of 0.40 mm, and a through-hole ratio of 19.6% were opened in the ceramic film sealing paper by mechanical needle punching technology. Example 3 A non-combustion heating type cigarette case manufactured from a ceramic film paper tube, a ceramic film sealing paper located at one end of the pipe, and a filter located at the other end of the pipe.

[0027] Its manufacturing method is as follows. That is, a ceramic film was coated on the rough surface of 50 gsm paper for manufacturing paper tubes to produce 60 gsm paper for ceramic film paper tubes. The paper for manufacturing ceramic film paper tubes was used as the innermost layer and wound in combination with two layers of 80 gsm paper for manufacturing paper tubes to manufacture a ceramic film paper tube. A ceramic film was coated on the rough surface of 70 gsm base paper, and an aluminum film was coated on the smooth surface to obtain 85 gsm ceramic film sealing paper. By using the press punching technology of the protruding plate and utilizing the arrangement of the punch pins on the protruding plate, pattern holes with a pore diameter of 0.15 mm and a total through-hole ratio of 15.0% were opened in the ceramic film sealing paper. Thereby, through-holes with good air permeability are formed, smooth suction can be performed, and the surface becomes beautiful and clean.

[0028] The above content is only a preferred embodiment of the present invention. It should be emphasized that various modifications and improvements made to the present invention by those skilled in the art without departing from the inventive concept of the present invention are all included in the scope of the claims of the present invention.
