AI Technical Summary

Technical Problem

The existing single-locking structure of bottle caps is prone to failure under high temperature or illegal operation, resulting in the failure of anti-counterfeiting function and inability to effectively prevent the bottle cap from being illegally pulled out.

Method used

A neck collar with a double-buckle structure is designed, including a main buckle and an anti-pull buckle. The main buckle forms a detachable fastening with the bottle mouth, and the anti-pull buckle matches the bevel of the bottle mouth. Combined with a fracture groove and anti-counterfeiting thread, it achieves mechanical self-locking and irreversible breakage.

Benefits of technology

It effectively prevents illegal cap removal, provides irreversible evidence of the break, ensures that the anti-counterfeiting function of the bottle cap is not damaged, and reduces the risk of counterfeiting and refilling.

Abstract

The anti-pulling wine bottle cap comprises a bottle cap body and the neck sleeve connected to a bottle opening in a sleeved mode, the upper row of annular buckle positions and the lower row of annular buckle positions on the inner wall of the neck sleeve are respectively provided with a main buckle position and an anti-pulling buckle position, and the outer wall of the bottle opening is correspondingly provided with a first buckle table matched with the main buckle position. A second buckling table matched with the anti-pulling buckling position is correspondingly arranged on the outer wall of the bottle opening; the buckling face of the second buckling table is an inclined face inclining downwards, the inclining direction of the inclined face is consistent with the buckling angle of the anti-pulling buckling position, and a fracture groove is formed in the connecting position of the neck sleeve and the bottle cap body. Through the combination of the main buckling position and the anti-pulling buckling position, the normal opening function is achieved, the anti-pulling core locking structure is additionally arranged, the anti-pulling buckling position is matched with the inclined face of the bottle opening, the root of the neck sleeve is broken when the cap is pulled out abnormally, meanwhile, the anti-fake silk thread is pulled apart, an unrecoverable burr-shaped fracture is generated, direct evidence is provided for authenticity verification, and the anti-fake bottle cap is safe and reliable. And counterfeit and secondary filling are effectively prevented.
