Anti-counterfeiting bottle cap

Abstract

The invention relates to an anti-counterfeiting bottle cap, and belongs to the technical field of bottle cap anti-counterfeiting. The anti-counterfeiting bottle cap comprises an inner cap; the inner cap sleeves a bottle opening, and has a wine outlet channel; one end of the outer surface of the inner cap, which is close to the bottle opening, is provided with multiple clamping grooves; the other end is provided with external threads; the periphery of the inner cap is sleeved by a connecting sleeve; clamping jaws matched with the clamping grooves are arranged on the inner surface of the connecting sleeve; one end of the inner cap, which is provided with the external threads, penetrates through the connecting sleeve; an inner plug for blocking the wine outlet channel is arranged at an end part of the inner cap; an anti-counterfeiting breaking ring is mounted on the connecting sleeve; multiple pawls are arranged at the end part of the connecting sleeve; the anti-counterfeiting breaking ring is provided with multiple ratchet grooves matched with the pawls; multiple breaking gaps are formed in a circumferential direction of the anti-counterfeiting breaking ring; the connecting sleeve is in threaded connection with a middle cap surrounding a screw cap; and a top cap for blocking a mounting cavity is mounted at the top of the middle cap. The bottle cap not only can achieve a bottle cap anti-counterfeiting effect, but also can solve the technical problem of poor sealing effect in reuse of the bottle cap after opening, and can be widely applied to wine anti-counterfeiting.

Description

technical field [0001] The invention relates to an anti-counterfeit sealing device, more particularly to an anti-counterfeit bottle cap, which belongs to the technical field of anti-counterfeit bottle caps. Background technique [0002] The main purpose of the bottle cap is to seal various containers, and according to different functions, it has different shapes and different operation methods. For example, the shape of the bottle cap of mineral water is usually round, and it needs to be twisted in the same direction when opening The caps of cans usually need to be pulled hard or pressed down; the caps of some meat cans have no fixed shape; and the caps of injection bottles commonly used in the medical field are usually glass. Use a grinding wheel or a sharp object to grind around it, and then pop it off; the most common beer bottle cap needs to be pried off... [0003] In short, in the field of bottle caps, there are all kinds of styles and opening methods, and designers h...
