Abstract

The invention discloses a novel irreversible anti-counterfeiting bottle cap which comprises an inner cap and an outer shell cap; the outer shell cap comprises an upper sleeve outer shell cap and a middle sleeve outer shell cap; the outer edge at the bottom of the inner cap is provided with a protruded part; a looping part of the middle sleeve outer shell cap is provided with a groove; before the bottle cap is opened, the protruded part on the outer edge at the bottom of the inner cap is hidden in the groove at the looping part of the middle sleeve outer shell cap; the outer side wall of the looping part of the middle sleeve outer shell cap is provided with a protruded circular boss; and the circular boss is around the upper part of the groove of the looping part. Compared with the prior art, the novel irreversible anti-counterfeiting bottle cap cannot be recovered into an original state after being opened, so that an irreversible anti-counterfeiting function is achieved.

Description

technical field [0001] The invention relates to the field of sealing devices, in particular to a novel irreversible anti-counterfeiting bottle cap. Background technique [0002] The bottle cap is an important part of wine packaging, and it is also the part where consumers first come into contact with the product. The bottle cap not only has the function of keeping the bottled product airtight, but also has safety functions such as anti-theft opening. In recent years, the market demand for bottle cap products has been stable and showing a growing trend, which promotes the continuous improvement of bottle caps, but most of the improvements are changes in the materials used. Compared with the changes in the structure of bottle caps, there is no substantial change. Improve. [0003] There are many kinds of anti-counterfeiting bottle caps for liquor. At present, there is an aluminum-plastic anti-counterfeiting bottle cap on the market. Its specific structure is as follows: Plea...

Problems solved by technology

[0004] But the aluminum-plastic anti-counterfeiting bottle cap of prior art can not really play irreversible anti-counterfeiting function in actual use, because inner cover 1 is molded with soft rubber, and its exposed part is softer, and other people use tool Against the outer edge of the bottom of the inner cap 1, the exposed part of the inner cap 1 can still be gradually squeezed back into the groove 22 of the mouth portion 21 of the outer shell cap 2, so that the entire bottle cap can be completely restored to its original state, and cannot be irreversible. Anti-counterfeiting function needs improvement
