Dual-open bottle cap anti-counterfeit device

Abstract

The invention relates to a dual-open bottle cap anti-counterfeit device. The device comprises a bottle cap, an anti-counterfeit ring and a lantern ring, wherein the bottle cap is in threaded connection with the lantern ring; the anti-counterfeit ring is in threaded connection with the lantern ring; direction of a spiral line by which the bottle cap is matched with the lantern ring is opposite to that of the spiral line by which the antic-counterfeit ring is matched with the lantern ring; a limit ratchet structure is arranged between the lower end of the bottle cap and the upper end of the anti-counterfeit ring; an irreversible clamp structure is arranged between the inner side of the anti-counterfeit ring and the outer side of the lantern ring; when the limit ratchet structure is fully separated, the clamp structure clamps and tightly locks; and after the clamp structure clamps and tightly locks, the bottle cap is unscrewed from the lantern ring. The invention also provides the dual-open bottle cap anti-counterfeit device of which the limit ratchet structure is replaced by the threaded connection between the lower end of the bottle cap and the upper end of the anti-counterfeit ring. In the two kinds of dual-open bottle cap anti-counterfeit devices, the anti-counterfeit structure of the bottle cap is simplified, the manufacturing cost is reduced, and the anti-counterfeit effectis better.

Description

【Technical field】 [0001] The invention relates to an accessory, a seal or an accessory used in a container for storing or transporting objects or materials, in particular to an anti-counterfeiting device for double-opening bottle caps used for an accessory, sealing or an accessory used in a container for storing or transporting an object or material. 【Background technique】 [0002] Under normal circumstances, the anti-counterfeiting of the outer packaging of bottled products is easy to be counterfeited by means of recycling the original outer packaging. After the bottle cap is opened for the first time, it shows obvious opening traces to prevent counterfeiting. The structure that cannot be restored after the bottle cap is opened prevents counterfeiting by means of recycling. Therefore, the anti-counterfeiting structure of the bottle cap is generally built into the bottle cap. , to avoid exposure, to prevent criminals from avoiding the anti-counterfeiting structure to open th...
