Description

technical field [0001] The invention relates to a bottle cap, in particular to an anti-counterfeiting bottle cap with self-locking and self-destruction functions. Background technique [0002] At present, there are many kinds of anti-counterfeiting wine bottle caps on the market, among which, the more common one is that the bottle cap includes an upper cap, a lower cap and a burst ring, and a plurality of notches for connecting points to be broken are distributed on the circumference of the burst ring. There are multiple tooth caps on the upper and lower end faces. When the bottle cap is tightened, the upper tooth cap is buckled in the square groove of the tooth ring at the mouth end of the upper cap, and the lower tooth cap is snapped into the tooth plate between the burst ring and the lower cap. In this way, when the upper cap is rotated When capping, the bursting ring will be broken along the connection point to be broken, and cannot be restored. In this way, the anti-co...

AI Technical Summary

Problems solved by technology

When the bottle cap is tightened, the upper tooth cap is buckled in the square groove of the gear ring at the mouth end of the upper cap, and the lower tooth cap is snapped into the tooth plate between the burst ring and the lower cap. In this way, when the upper cap is rotated When capping, the burst ring will be broken along the connection point to be broken and cannot be restored. This method is used to achieve the purpose of anti-counterfeiting. After the burst ring is damaged, the overall damage is more obvious, which affects the overall appearance of the bottle cap.

[0003] In addition, although the above-mentioned bottle cap has a self-destruct function, the wine bottle can still be reused by destroying the lower cap installed on the mouth of the wine bottle, leaving a certain space for counterfeiting
