Description

Technical Field

[0001] This utility model belongs to the field of heated cigarette technology, specifically relating to a heated cigarette using homologous paper material. Background Technology

[0002] Heated cigarettes, as a novel tobacco product, have rapidly become a significant innovation in the global tobacco industry in recent years, maintaining rapid sales growth in overseas markets for many consecutive years. Common heated cigarettes share a similar core structure with traditional cigarettes, consisting of two key components: the tobacco section and the filter section. The tobacco section is typically made of shredded tobacco or reconstituted tobacco leaves, releasing an aerosol containing nicotine and aroma components when heated. The filter section is usually made of a composite of multiple materials, serving to extract smoke, lower the aerosol temperature, and provide support. Heated cigarettes require a device to heat and generate the aerosol during smoking. The device heats the tobacco section using electromagnetic, infrared, or microwave methods. Based on the location of the heat source and the tobacco section, heated cigarettes can be broadly categorized into inner-core products (where the heat source is inside the tobacco section) and circumferential products (where the heat source is outside the tobacco section).

[0003] When smoking heated cigarettes, the smoking device needs to continuously heat the tobacco segment. The paper material near the tobacco segment is also heated by the device, which causes some unexpected components to be released from the paper material, producing off-flavors and affecting the sensory quality of the cigarette.

[0004] Therefore, how to design a heated cigarette using homogeneous paper materials to reduce the generation of impurities when the paper materials are heated has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a heated cigarette using homologous paper material to solve the aforementioned technical problems in the prior art.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A heated cigarette using homologous paper materials includes a smoking substrate, cigarette paper, forming paper, and tipping paper. The raw materials for producing the smoking substrate include homologous tobacco products, and the raw materials for producing at least one of the cigarette paper, forming paper, and tipping paper include homologous tobacco products.

[0008] Preferably, the raw material formula of the homologous tobacco leaf products includes at least three tobacco leaf raw materials, and the different tobacco leaf raw materials have at least one difference in terms of variety, origin, year, and part of the plant.

[0009] Preferably, the raw materials for producing the smoking substrate, cigarette paper, forming paper, and tipping paper also include other tobacco leaf products besides those from the same source, and the formula for producing other tobacco leaf products differs from the formula for producing tobacco leaf products from the same source by at least two types of tobacco leaf raw materials.

[0010] Preferably, the tobacco leaf products from the same source in the production raw materials of the smoking substrate, cigarette paper, forming paper, and tipping paper have a strong correlation, and the tobacco leaf products with a strong correlation are made from the same batch of raw materials.

[0011] Preferably, each homologous tobacco product is an intermediate or final product of a multi-step process involving the same batch of raw materials.

[0012] Preferably, the raw materials used in the production of the smoking substrate, cigarette paper, forming paper, and tipping paper are the same type of tobacco leaf products.

[0013] Preferably, the types of tobacco leaf products used in the production of the smoking substrate, cigarette paper, forming paper, and tipping paper are different.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention relates to heated cigarettes made from homologous paper materials. By adding homologous tobacco products to at least one of the raw materials used in the production of cigarette paper, forming paper, and tipping paper, these paper materials release aroma components when heated, thereby effectively reducing the generation of off-flavors and improving the sensory quality of the cigarettes. Attached Figure Description

[0016] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the embodiments will be briefly described below, and the specific embodiments of this utility model will be further described in detail with reference to the drawings.

[0020] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0021] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0022] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0023] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0024] like Figure 1 As shown, this utility model embodiment provides a heated cigarette using homologous paper material, which includes a smoking substrate 12, cigarette paper, forming paper, and tipping paper. The raw materials for producing the smoking substrate include homologous tobacco products, and at least one of the cigarette paper, forming paper, and tipping paper includes homologous tobacco products in its raw materials.

[0025] The heated cigarettes using homologous paper materials provided in this embodiment of the invention add homologous tobacco leaf products to the production raw materials of at least one of the cigarette paper, forming paper, and tipping paper, so that these paper materials release aroma components when heated, thereby effectively reducing the generation of impurities and improving the sensory quality of the cigarettes.

[0026] Furthermore, the raw material formula of homologous tobacco leaf products must include at least three tobacco leaf raw materials, with at least one difference in variety, origin, year, or part of the plant. Understandably, the quantity of tobacco leaf raw materials and the proportion of each type in the formula of homologous tobacco leaf products can be flexibly set according to actual circumstances.

[0027] Preferably, the raw materials for producing the smoking substrate 12, cigarette paper, forming paper, and tipping paper also include other tobacco products besides those from the same source, and the formula for making other tobacco products differs from the formula for making tobacco products from the same source by at least two types of tobacco raw materials.

[0028] Specifically, there is a strong correlation between the raw materials used in the production of smoking substrate, cigarette paper, forming paper, and tipping paper, and these tobacco leaf products with strong correlation are made from the same batch of raw materials.

[0029] Each homologous tobacco product is an intermediate or final product of a multi-step process involving the same batch of raw materials. This process ensures that the aroma characteristics released by cigarette paper, forming paper, and tipping paper during heating are more consistent with the mainstream smoke characteristics of the tobacco substrate, thereby improving the aroma quality of cigarettes.

[0030] Preferably, when using highly correlated homologous tobacco products, homologous tobacco products obtained in later steps of the multi-step process are preferentially used in the front end of heated cigarettes, while homologous tobacco products obtained in earlier steps of the multi-step process are preferentially used in the rear end of heated cigarettes. This means that when a heated cigarette is smoked, the end closer to the mouth is the rear end, and the end further away from the mouth is the front end.

[0031] Specifically, the processing includes changes in the morphology of tobacco raw materials, such as extrusion, folding, shredding, and crushing; extraction of some substances from tobacco raw materials, such as extraction, distillation, and pressing; and chemical modification of tobacco raw materials, such as smoking, high-temperature / high-pressure treatment, and fermentation.

[0032] Preferably, the raw materials used in the production of the smoking substrate 12, cigarette paper, forming paper, and tipping paper are all from the same source of tobacco leaves. This approach ensures that the aroma characteristics released from the paper materials—cigarette paper, forming paper, and tipping paper—during heating are consistent with the mainstream smoke characteristics of the smoking substrate, thereby further improving the aroma quality and sensory experience of cigarettes.

[0033] Specifically, in other embodiments, the types of homologous tobacco products used in the production raw materials of the smoking substrate, cigarette paper, forming paper, and tipping paper are different.

[0034] In another embodiment, the same homologous tobacco product is used as the raw material for the production of two or three of the following: the smoking substrate, cigarette paper, forming paper, and tipping paper.

[0035] In a specific embodiment, the specific raw material formula for the homologous tobacco leaf product can be as follows:

[0036] 1. 15 samples of Hubei Burley tobacco from 2020;

[0037] 2. 15 portions of Malawi Burley tobacco from 2020;

[0038] 3. Ten portions of Sichuan sun-dried red tobacco produced in 2021;

[0039] 4. Five samples of Yunnan sun-dried tobacco from 2019;

[0040] 5. 10 samples of Yunnan aromatic tobacco from 2020;

[0041] 6. Five samples of flue-cured tobacco from central Fujian in 2020;

[0042] 7. Seven samples of flue-cured tobacco from central Yunnan in 2021;

[0043] 8. Eight samples of flue-cured tobacco from central Hunan in 2020.

[0044] All tobacco leaf raw materials were blended according to the above formula and ground through a 250-mesh sieve. The resulting tobacco powder was used as the first homologous tobacco product. An extract was prepared using water extraction, and the remaining solid residue was collected. The water extract was then fermented using bio-fermentation, and the resulting solid substance was collected as the second homologous tobacco product. The solid residue was concentrated to separate most of the water, and the extract was refined using molecular distillation. The heavy phase fraction was collected as the third homologous tobacco product.

[0045] The reconstituted tobacco (as a smoking base material) process used Type 1 and Type 3 homologous tobacco products. In addition, tobacco powder based on other formulations was also used. The other formulations are as follows:

[0046] 1. 6 portions of Zambian flue-cured tobacco from 2020;

[0047] 2. Six samples of US flue-cured tobacco from 2020;

[0048] 3. Eight samples of flue-cured tobacco from central Fujian in 2021;

[0049] The cigarette paper was made using a second type of tobacco product from the same source.

[0050] This invention reduces the problem of off-flavors generated during cigarette heating due to the heating of adjacent paper materials. It employs a multi-step process to process tobacco leaves with the same formulation as the cigarette-generating substrate, collecting the products from different steps and adding them to the paper material to generate aroma components upon heating. The remaining raw materials can be reused as the cigarette-generating substrate, reducing waste during production. Furthermore, using the same formulation in both the cigarette-generating substrate and paper material ensures that the aroma characteristics released from the paper material (i.e., cigarette paper, forming paper, tipping paper) are consistent with the mainstream smoke characteristics released from the cigarette-generating substrate, thus improving the aroma quality and quantity of the cigarette and the sensory experience during smoking.

[0051] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
