Abstract
Description
Technical Field
[0001] This invention belongs to the field of heated cigarette technology, specifically relating to a method for reducing unpleasant odors and oral compound residues from heated cigarettes, and heated cigarettes themselves. Background Technology
[0002] In this art, it is known that aerosol-generating articles, in which the aerosol-generating matrix is heated but not burned, vaporize volatile compounds in the aerosol-generating matrix during use. The vaporized high-temperature compounds are then condensed through a specific aerosol pathway to form an aerosol for the user to inhale. When aerosol-generating articles are heated by consumers, the production of unpleasant odors and oral compound residues is one of the main reasons for sensory rejection. These unpleasant odors and oral compound residues are usually caused by long-chain compounds volatilized after the article is heated.
[0003] Among them, products that are heated by the heating device from the outside of the product through heat conduction or electromagnetic radiation to form an aerosol that can be inhaled are more likely to produce unpleasant odors and oral compound residues. This is because the heat needs to penetrate the multiple layers of packaging paper that wrap the tobacco material and the glue that must be applied between the packaging papers when the product is manufactured. When the packaging paper and glue are heated, compounds that produce unpleasant odors will inevitably volatilize and lead to oral compound residues.
[0004] Therefore, for aerosol-generated articles heated from the outside of the article by heat conduction or heat radiation, it is desirable to provide a method that can minimize unpleasant odors and oral compound residues, as well as an aerosol-generated article, to meet the sensory needs of the consumer group of this type of aerosol-generated article. Summary of the Invention
[0005] The present invention provides a method for reducing unpleasant odors and oral compound residues in products generated by aerosols heated from the exterior of the product through thermal conduction or electromagnetic radiation. This method can significantly reduce the content of long-chain compounds volatilized from the product after heating, thereby improving the sensory experience of consumers of this type of product.
[0006] To achieve the above objectives, this application employs the following technical solution:
[0007] A method for reducing unpleasant odors and oral compound residues from heated cigarettes includes an aerosol generating matrix strip, the aerosol generating matrix strip comprising a first paper wrapping material wrapped with tobacco material, and a second paper wrapping material bonded to the first paper wrapping material with adhesive to encapsulate at least a portion of the aerosol generating matrix strip within the aerosol generating article;
[0008] The fibers contained in both the first and second paper packaging materials are derived from hemp pulp fibers or bamboo pulp fibers;
[0009] There is a discontinuous sizing area between the first paper packaging and the second paper packaging, and the total area of the sizing area is between 40% and 80% of the outer surface area of the aerosol generating matrix strip.
[0010] Furthermore, the first paper packaging material has a strength of 27g / m³. 2 up to 35g / m 2 The quantitative value of the second paper packaging material is 32 g / m³. 2 Up to 42 g / m 2 Quantitatively.
[0011] Furthermore, when used in conjunction with a heating device that heats the matrix strip generated by electromagnetic radiation surrounding the aerosol, the relative permittivity of the first paper packaging material is 1-35 and the relative permittivity of the second paper packaging material is 2-15 under electromagnetic radiation frequency conditions of 40Hz-10MHz.
[0012] Furthermore, one of the following methods is used between the first paper packaging and the second paper packaging: annular interval glue application, longitudinal strip interval glue application, or dot glue application.
[0013] Furthermore, the annular interval application forms a total of no more than four application areas, the longitudinal interval application forms a total of no more than six application areas, and the spot application forms a total of at least eight application areas.
[0014] A heated cigarette includes an aerosol generating matrix strip as described above, a plug element is disposed upstream of the aerosol generating matrix strip, and a second paper packaging material simultaneously wraps the plug element.
[0015] Furthermore, a filter element is provided at the downstream end of the aerosol generating matrix strip. The filter element is made of cellulose acetate, polylactic acid, or paper-based material wrapped in paper packaging, and the length of the filter element is 5-15 mm.
[0016] Furthermore, downstream of the aerosol generating matrix strip and upstream of the filter element is a hollow tube with ventilation holes on its sidewalls and a hardness greater than 72%.
[0017] Furthermore, the ratio of the inner diameter of the downstream hollow tube that contacts the aerosol generating matrix strip to the diameter of the aerosol generating matrix strip is 0.415-0.692.
[0018] The beneficial effects of this invention are:
[0019] This technical solution addresses the problem of unpleasant odors and oral compound residues that easily arise from aerosols generated by heating the exterior of products through heat conduction or electromagnetic radiation. By screening the fibers within the paper packaging that encapsulates the aerosol matrix, optimizing the quantitative parameters of the paper packaging, and designing the sizing method, the material basis for the formation of unpleasant odors and oral compound residues is reduced from the source.

[0028] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings. The following embodiments are merely exemplary and can only be used to explain and illustrate the technical solution of the present invention, and should not be construed as limiting the technical solution of the present invention.
[0029] This application provides a method for reducing unpleasant odors and oral compound residues in aerosol-generating products during use. The main improvement involves refining the multi-layered packaging paper surrounding the aerosol-generating matrix, and simultaneously improving the application area of adhesive between the multi-layered packaging paper layers. This technical solution does not involve any improvement to the aerosol matrix strip, i.e., the tobacco material.
[0030] The aerosol generating articles involved in this application are mainly used in conjunction with a heating device that heats the aerosol generating matrix strip by heat conduction or electromagnetic radiation.
[0031] The aerosol-generating article of this application includes an aerosol-generating matrix strip, which is made by wrapping tobacco material in a first paper package. A second paper package is glued to the first paper package, at least a portion of the aerosol-generating matrix strip is packaged inside the aerosol-generating article. The fibers contained in both the first and second paper packages are derived from hemp pulp fibers or bamboo pulp fibers. The first paper package has a fiber content of 27 g / m³. 2 up to 35g / m 2 The quantitative value of the second paper packaging material is 32 g / m³. 2 Up to 42 g / m 2 Quantitatively.
[0032] There is a discontinuous adhesive application area between the first paper packaging 1 and the second paper packaging 2, and the total area of the adhesive application area is between 40% and 80% of the outer surface area of the aerosol generating matrix strip 3. The adhesive application between the first paper packaging 1 and the second paper packaging 2 is performed in a ring-shaped interval, or in longitudinal strip intervals, or in a dotted pattern, forming a structure such as... Figure 1 The annular spaced adhesive application area 4 shown, or as... Figure 2 The longitudinally spaced adhesive application area 5 shown, or as... Figure 3 The area shown as the dotted adhesive application zone 6 is not coated with adhesive in the area between the first and second paper packaging materials outside the adhesive application zone.
[0033] In this application, the annular interval application forms a total of no more than four application areas, the longitudinal interval application forms a total of no more than six application areas, and the spot application forms a total of at least eight application areas.
[0034] like Figures 4 to 6 As shown, this application provides a heated cigarette, including an aerosol generating matrix strip as described above, with a plug element disposed upstream of the aerosol generating matrix strip, and a second paper packaging material simultaneously wrapping the plug element.
[0035] The downstream end of the aerosol generating matrix has a filter element, which is usually made of cellulose acetate, polylactic acid or paper-based material wrapped in paper packaging, and the filter element is 5-15mm long.
[0036] The filter element is arranged downstream of the aerosol generating matrix strip and upstream of the filter element. The hollow tube has ventilation holes on its side wall and a hardness greater than 72%.
[0037] The ratio of the inner diameter of the downstream hollow tube that contacts the aerosol generating matrix strip to the diameter of the aerosol generating matrix strip is 0.415-0.692.
[0038] When the aerosol-generated product is inserted into the aerosol-generating device, air enters the aerosol-generating product through the end face of the upstream plug element or the aerosol-generating matrix strip and ventilation holes.
[0039] When the aerosol generating product is inserted into the aerosol generating device, the aerosol generating matrix receives heat from the heat conduction of the aerosol generating device or electromagnetic radiation to generate volatile compounds.
[0040] When used in conjunction with a heating device that heats a matrix strip generated by electromagnetic radiation surrounding aerosols, the relative permittivity of the first paper packaging is 1-35 and the relative permittivity of the second paper packaging is 2-15 under electromagnetic radiation frequency conditions of 40Hz-10MHz.
[0041] This application addresses the problem of unpleasant odors and oral compound residues in products generated by aerosols heated externally via heat conduction or electromagnetic radiation. It specifically selects hemp pulp fiber paper or bamboo pulp fiber paper packaging materials that do not easily release long-chain carbon compounds when heated. Furthermore, it optimizes the adhesive application area of the product, minimizing the adhesive application area (reducing the amount of adhesive applied), thus reducing the material basis for unpleasant odors and oral compound residues. Simultaneously, it limits the quantitative amounts of the first and second paper packaging materials, constructing an adhesive application method that minimizes the air gap between the first and second paper packaging materials to facilitate rapid heat penetration.
[0042] like Figure 4 As shown, the aerosol-generating product includes: an aerosol-generating matrix strip 7, a first paper packaging 8, a second paper packaging 9, a ventilation hole 10, a hollow tube with through holes 11, a hollow tube 12, a filter element 13, an inlet end 14 of the aerosol-generating product, and a distal end 15 of the aerosol-generating product. The aerosol-generating matrix strip is made of shredded, randomly arranged reconstituted tobacco material or shredded, randomly arranged tobacco shreds. The first paper packaging has a basis weight of 28.5 ± 1 g / m³. 2 The basis weight of the second paper packaging material was 39±1g / m³. 2 Both types of paper packaging materials contain hemp fibers.
[0043] like Figure 5 As shown, the aerosol generating article involved in this application includes: an aerosol generating matrix strip 16, a first paper packaging 17, a second paper packaging 18, a ventilation hole 19, a hollow tube with through holes 20, a hollow tube 21, a filter element 22, a plug element 23, a plug sheath layer 24, a plug core layer 25, an aerosol generating article port end 26, and an aerosol generating article distal end 27.
[0044] like Figure 6As shown, the aerosol generating article involved in this application includes: an aerosol generating matrix strip 28, a hollow tube 29 abutting the aerosol generating matrix, a ventilation hole 30, a hollow tube 31, a filter element 32, a plug element 33, a plug sheath layer 34, a plug core layer 35, a distal end 36 of the aerosol generating article, and an inlet end 37 of the aerosol generating article.
[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the specific implementation of the present invention.
