Description

TECHNICAL FIELD

[0001] The utility model belongs to the cigarette technical field, concretely relates to a sheet material. BACKGROUND

[0002] With the increasing concern of people in various countries for health, heat-not-burn cigarettes gradually enter the public view due to their low harm. Heat-not-burn cigarettes are a product that generates aerosol by cooperating with a heating smoking set, and the heating temperature generally reaches 200-400℃, and since there is no high-temperature cracking process due to no combustion, the release of harmful substances is greatly reduced. In order to enable consumers to have a good consumption experience, the temperature at the inlet of smoke should be low, and the aroma should be full and abundant. This requires the full volatilization of the heat-not-burn cigarette core, and the cigarette should have certain aroma-carrying capacity and good cooling effect.

[0003] At present, the common cooling methods for heat-not-burn cigarette products include: using a thin film gathered by pleats, designing a spiral structure to increase the length of the air channel, and using a hollow tube to utilize the Venturi effect for cooling. The existing cooling methods mainly have the problems of complex processing technology, high production cost, large aroma retention, and poor cooling effect.

[0004] For the aroma addition of heat-not-burn cigarettes, the main current method is to add a burst bead in the filter rod of the heat-not-burn cigarette, or directly mix a flavoring essence in the cigarette core material. However, the production cost of the burst bead is high, and the aroma is not uniformly released, while the mixing of the flavoring essence in the cigarette core material easily causes poor aroma release stability and affects the aroma release of the cigarette core material. Patent CN109846084A reports the use of polylactic acid filament composite filter rods for cooling, the gaps between the polylactic acid filaments are filled with a filler, and the circumferential surfaces of the polylactic acid filaments and the filler are uniformly coated with a plasticizer or a filter rod forming binder. However, the filler between the polylactic acid filaments may volatilize with the smoke during smoking, causing an undesirable smoking experience. Patent CN210043187U reports that aroma and cooling are achieved by gathering polylactic acid film and placing non-woven fabric in the middle. However, the aroma-carrying capacity of the non-woven fabric is limited, and the processing technology is complex and the processing cost is high.

[0005] Therefore, the utility model is proposed. UTILITY MODEL CONTENT

[0044] Embodiment 2: the sheet material obtained in embodiment 1 is used in the cooling section of the heating non-combustion cigarette.

[0045] When the sheet material obtained in embodiment 1 is used as the cooling section of the heating non-combustion cigarette, the sheet base material is polylactic acid, the sheet base material is formed into a cylindrical rod by gathering, the rectangular convex frame 101 of 2mm of the sheet material separates the surfaces of adjacent sheet materials, and the through hole 102 on the surface of the convex frame 101 forms a porous high-air-permeability cooling section. When the aerosol after heating flows into the cooling section from the tobacco core section, the temperature of the aerosol is reduced due to the physical properties of the polylactic acid material itself, and the interception of the heated cigarette smoke is greatly reduced due to the structure characteristics of the porous and high-air-permeability.

[0046] Embodiment 3: the sheet material obtained in embodiment 1 is used in the flavoring section of the heating non-combustion cigarette.

[0047] The sheet material obtained in Embodiment 1 is used as a flavoring section of a heat-not-burn cigarette. The essence gel mixture is evenly applied on the upper surface of the sheet material with the rectangular protrusions 101, the sheet material is gathered to form a cylindrical shape, at this time, the essence gel mixture is evenly distributed between the surfaces of the sheet material, at this time, the 2mm rectangular protrusions 101 provide strong support for the essence gel mixture, and then the formed paper with anti-permeability function is wrapped. After the processing of the flavoring section is completed, it is installed between the support section and the filter section of the heat-not-burn cigarette. When smoking, the tobacco core section is heated by the heating appliance to release aerosol, when passing through the flavoring section, the essence gel mixture applied on the sheet material releases aroma. Because the sheet material of the present application has a higher flavor carrying capacity, the gas entering the oral cavity from the filter section is full of aroma.

[0048] The base material of the sheet material of the present embodiment is polylactic acid. Since polylactic acid can also be used as a cooling material, the flavoring section of the present embodiment has both flavoring and cooling effects. In this way, only one cylindrical section of the sheet material of the present application has both cooling and flavoring effects. The flavoring section of the present embodiment has good cooling effect while increasing the stable release of aroma, reducing the processing procedures of the heat-not-burn cigarette and reducing the cost.
