Anti-counterfeiting bottle cap adhered with colored printing thin film

Abstract

The invention relates to an anti-counterfeiting bottle cap adhered with a colored printing thin film. The anti-counterfeiting bottle cap comprises a shell and an anti-counterfeiting film which is arranged on the shell and used for covering the shell; the anti-counterfeiting bottle cap is prepared by the following processes and steps: (1) printing a layer of colored pattern on the back of a transparent plastic thin film, and forming a colored printing layer on the thin layer through back print; (2) forming a metal layer on the printing layer through metal transfer; (3) covering the anti-counterfeiting film on the shell of the bottle cap, and arranging an opening guide structure on the anti-counterfeiting film; (4) using a thermal contraction film as the plastic thin film as; and (5) arranging an opening crevasse and a rupture hidden line on the anti-counterfeiting film, and connecting the crevasse with the opening structure of the bottle cap. As the pattern is machined on the plastic thin film with metal sensation, different effects such as colored printing, metallic luster and the like can be realized in the same plane so as to reduce the production cost, improve the efficiency, and stabilize the quality.

Description

technical field [0001] The invention relates to an anti-counterfeiting bottle cap with a color printing sheet veneer. Background technique [0002] Most of the current anti-counterfeiting bottle caps work hard on the structure of the bottle cap, and use the structural characteristics of the bottle cap itself to achieve the purpose of anti-counterfeiting. Chinese patent CN2124208U discloses a kind of " anti-counterfeiting bottle cap " and it is to utilize the mark on the bottle cap to reach the anti-counterfeiting purpose for the scratch that bottle body produces. But the anti-counterfeit effect of this anti-counterfeit bottle cap is not ideal. [0003] In recent years, with the improvement of people's requirements for product appearance and quality, printing technology and packaging technology have made great progress. However, since the bottle cap is made of plastic or metal, color printing cannot be carried out directly on the plastic or metal. However, the existing pro...

AI Technical Summary

Problems solved by technology

However, since the bottle cap is made of plastic or metal, it is not possible to directly print in color on plastic or metal

However, the existing production processes also have the following disadvantages: 1. Electroplating is not environmentally friendly, and electroplating is all plating, and partial patterns cannot be realized; 2. The efficiency of silk screen printing is low, the color is not true, and it cannot be full-color, and it is easy to print after silk screen printing. Quality problems occur; 3. The transfer printing is easy to fade, the authenticity is reduced, and there is no protection when exposed to the outside; 4. The cost of painting is high, the efficiency is low, and there is only one color, and the color is monotonous
