Description

Technical Field

[0001] The utility model relates to the technical field of bottle caps, in particular to an anti-twist double aluminum tube anti-counterfeit bottle cap and a container bottle. Background Art

[0002] At present, the mechanical anti-counterfeiting methods of wine bottle caps mainly include pry-off type, twist-off type, top-open type and violent ring type, etc. Their common feature is to destroy the connection point to achieve the purpose of anti-counterfeiting. For the twist-off anti-counterfeiting, in the prior art, the bottle cap usually includes an outer aluminum cylinder, a cover body and a sealing plug sleeve. The sealing plug sleeve is pressed on the bottle mouth after assembly. The cover body is connected to the sealing plug sleeve through a thread so that the bottle cap can be opened by rotating the cover body. The outer aluminum cylinder is set on the outside of the cover body, and hot melt adhesive is filled between the outer aluminum cylinder and the cover body to achieve a fixed connection between the two. The lower end of the outer aluminum cylinder is fixed to the sealing plug sleeve by a flange. The outer aluminum cylinder is provided with a twist-off connection point. When opening the bottle cap, the outer aluminum cylinder needs to be twisted off, thereby playing an anti-counterfeiting role.

[0003] However, since the outer aluminum tube and the bottle cap body are fixed with hot-melt adhesive, criminals can easily break the hot-melt adhesive by twisting the outer aluminum tube, and then violently pull out the outer aluminum tube, open the cap and replace the genuine wine. Therefore, the anti-counterfeiting bottle caps in the prior art only need to remake the outer aluminum tube, and can achieve the purpose of counterfeiting at a very low cost, and the anti-counterfeiting effect is poor.
