Abstract

The invention discloses an anti-counterfeiting self-locking limit bottle cap, and relates to a bottle cap for a drink bottle. An inner cap is arranged in a shell, and is connected with a connecting cap through threads; the outer surface of the lower end of the connecting cap is matched with the inner surface of an inner plug; the connecting cap is hollow, the upper end is provided with threads, the middle is at least provided with a rotation preventing strip, the lower end is provided with a conical section, and a separation stop groove is formed below the conical section; and the outer surface of the inner plug is provided with a plurality of seal rings, and the lower end of the inner plug is provided with a plurality of wedge blocks. By matching the outer surface of the lower end of theconnecting cap and the inner surface of the inner plug and under the action of the conical section of the lower end of the connecting cover, the plurality of wedge blocks at the lower end of the inner plug are opened and locked by the separation stop groove, so that the inner plug and the connecting cap are firmly locked in a bottleneck of a bottle body, and a reliable seal is formed through the seal rings on the outer surface of the inner plug. The anti-counterfeiting self-locking limit bottle cap is firmly arranged on the bottle body, has good effect of sealing liquid in the bottle body, has an attractive appearance and can realize the anti-counterfeiting function.

Description

technical field

[0001] The invention relates to a bottle cap for a beverage bottle, in particular to an anti-counterfeit self-locking limit bottle cap suitable for use 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, 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. . Ceramic bottle caps are not easy to fire, and the cost is high, and ceramic bottle caps are relatively brittle, and because of their structure, they are easily damaged during transportation. Contents of the invention

[0003] The technical problem to be solved by the present invention is to provide an anti-counterfeit self-locking limit bottle cap, which can ensure the sealing of the bottle cap, and ha...
