Problems solved by technology

[0002] The tolerance error of the inner diameter of the mouth of the existing ceramic bottle after firing is relatively large, which can reach more than 1mm, and the cooperation with the ordinary bottle cap often causes the leakage of the liquid in the bottle, or the volatilization of alcohol, and the ceramic bottle mouth is not easy to make threads.
Ordinary ceramic bottle caps are relatively brittle, and because of their structure, they are easily damaged during transportation

Abstract

The invention discloses an anti-fake self-locking bottle cover, which relates to a bottle cover for a drink bottle. An inner cover is installed in a shell, the inner cover is connected with a connecting cover by a thread, the outer surface on the lower end of the connecting cover is matched with the inner surface of an inner plunger; the connecting cover is of a hollow structure and provided witha conical section on the lower end, a stop groove is arranged under the conical section; and the inner plunger is provided with multiple sealing rings on the outer surface and multiple wedge blocks on the lower end. Through the matching between the outer surface on the lower end of the connecting cover and the inner surface of the inner plunger, the inner plunger and the connecting cover are fixedly locked in the bottle neck of the bottle, and a reliable sealing effect is formed by a sealing ring on the outer surface of the inner plunger. An outer slot and an inner slot are engaged with a breaking ear on the bottle body, the breaking ear is broken when the bottle cover is opened firstly, thus the purpose of preventing fake is achieved, and the bottle body is not damaged to favor the storage of the bottle body. The anti-fake self-locking bottle cover has fixed installation on the bottle body, good sealing performance for the fluid in the bottle, attractive appearance and an anti-fake function.

Description

Technical field [0001] The invention relates to a bottle cap for a beverage bottle, in particular to an anti-counterfeiting self-locking bottle cap used on a wine bottle made of ceramics. Background technique [0002] The tolerance error of the inner diameter of the mouth of the existing ceramic bottle after firing is relatively large, which can reach more than 1mm. The cooperation with the ordinary bottle cap often causes the leakage of the liquid in the bottle or the volatilization of alcohol, and the ceramic bottle mouth is not easy to make threads. . Ordinary ceramic bottle caps are relatively brittle, because of their structure, they are easily damaged during transportation. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-counterfeiting self-locking bottle cap, which can ensure the sealing of the bottle cap, has exquisite appearance, is conducive to modeling and production, and can be anti-counterfeit. [000...
