Stop gear positioning structure of anti-counterfeit winebottle cap

Abstract

The invention provides a retaining tooth limit structure of an anti-counterfeit wine bottle cap and belongs to the technical field of liquid container protection and sealing cap repeated use prevention. The limit structure comprises an upper cap (1) with internal threads (7) and a connecting cap (2) with external threads (9), and is characterized in that: the lower part of the upper cap (1) is also provided with internal retaining teeth (4); and the outside of the connecting cap (2) is provided with external retaining teeth (3) at positions corresponding to that of the internal teeth (4). When the cap is screwed off, the upper cap moves upward as a whole, and when the internal retaining tooth of the upper cap meet the external retaining teeth of the connecting cap, the internal retaining teeth can slide over smoothly to open the bottle cap. When the cap is fastened again, the internal retaining teeth and the external teeth can be just closed oppositely due to the fact that the clockwise rotation angle of the internal retaining teeth of the upper cover is just opposite to the angle of the external retaining teeth of the connecting cap and an obvious gap is formed between the upper cover and a lower sleeve, so whether or not the bottle cap is opened can be judged. The structure has the advantages of reasonable design and permanent anti-counterfeit effect due to the hidden anti-counterfeit mechanism.

Description

technical field [0001] The invention relates to a tooth-stopping and position-limiting structure of an anti-counterfeit wine bottle cap, which belongs to the technical field of manufacturing liquid container protection and sealing caps for preventing repeated use. Background technique [0002] Existing aluminum-plastic or all-plastic anti-counterfeiting wine bottle caps, from the product structure analysis, wherein the inner cap and connecting cap are indispensable parts. In the design of anti-counterfeiting effect, the following methods are generally adopted, all of which have some defects to varying degrees: [0003] 1. The safety ring is a single part. After the product is opened, the safety ring breaks into two parts. Since the safety ring is a separate part, the assembly is complicated, and the processing efficiency and pass rate are relatively low. [0004] 2. The upper cover and the safety ring are a whole. Before assembly, use a cutting machine to keep only 6-8 con...

AI Technical Summary

Problems solved by technology

However, after the upper cover is rotated and opened, when the bell mouth ring comes out from the groove edge of the aluminum cover, since the edge of the aluminum cover is relatively sharp, it is easy to generate plastic waste, and the hygienic effect is not good; The ring ring of the bell mouth is relatively thin, and it is easy to break or fall off the whole ring, thus losing the anti-counterfeiting effect
