Embodiment 1
[0042] Embodiment one: a kind of anti-counterfeit gasket for bottle cap, such as figure 1 As shown, it includes: a gasket substrate 1 for carrying anti-counterfeiting information; A protective film layer 2 for displaying anti-counterfeiting information.
[0043] The gasket base 1 is made of low-density polyethylene material, which has a certain thickness and elasticity. The thickness of the gasket base 1 is 1mm, and in other embodiments, it can also be 0.5mm, 0.6mm, 0.7mm, 0.8mm , 0.9mm, 1.1mm or 1.2mm, because a certain elastic deformation can occur when embedded in the bottle cap, so the installation process is more convenient.
[0044] The anti-counterfeiting information is formed on the gasket substrate 1 by UV ink through printing or code spraying. The anti-counterfeiting information is a two-dimensional code corresponding to the commodity. In other embodiments, the anti-counterfeiting information can also be a barcode, a serial number, or a verification code. One or mo...
Embodiment 2
[0050] Embodiment two: a kind of manufacture method of anti-counterfeit gasket for bottle cap, such as Figure 2 to Figure 4 As shown, it includes: processing and forming the gasket base material 61, which has several areas bearing anti-counterfeiting information on the gasket base material 61, and each area on the gasket base material 61 will generate a gasket base 1; The side of the material 61 bearing the anti-counterfeiting information covers the protective film layer material 62, and is bonded to the gasket base material 61 through a vulcanization process to form the first processed body 6, and the protective film layer material 62 corresponding to each area will be formed for Cover the anti-counterfeiting information to isolate the anti-counterfeiting information from the external environment and make the protective film layer 2 of the anti-counterfeiting information appear; at the surface of the gasket base material 61 opposite to the anti-counterfeiting information, the...
