Anti-counterfeit bottle cap

Abstract

The invention provides an anti-fake bottle cap. The anti-fake bottle cap comprises a cap body, and an anti-fake ring which is connected with the cap body, wherein a gap and a groove for stopping rotating are formed in the anti-fake ring, and the gap is positioned in the outer side of the anti-fake ring; an anti-fake two-dimensional code or an anti-fake pattern is arranged on the outer surface of the anti-fake ring; the gap is treated as a part of the anti-fake two-dimensional code or the anti-fake pattern according to the shape. According to the anti-fake bottle cap, the gap is treated as a part of the anti-fake two-dimensional code or the anti-fake pattern according to the shape; when the bottle cap is opened for the first time, the groove which is formed in the anti-fake ring and used for stopping rotating cannot rotate together with the cap body, relative to a bottle, and can be torn at the gap with relative weak connection, then the gap is deformed or broken and the anti-fake two-dimensional code or the anti-fake pattern is invalid, and thus the anti-fake purpose is achieved; in addition, the anti-fake two-dimensional code or the anti-fake pattern is difficultly recovered. The invention further provides an anti-fake bottle cap with the gap formed in the inner side of the anti-fake ring.
