Abstract

The invention provides a structure that can prevent liquid substances in a bottle cover from leaking, which mainly comprises that a hollow containing chamber is arranged in a bottle cover body, a circle of lining ring body is branch-extended and arranged at the wall surface towards the direction of a channel connecting the cover to lead the external surface of the lining ring body and the internal wall of the channel connecting the cover to form an elastic gap, and a circle of buckled groove is concavely arranged at the internal edge surface of the lining ring body; in addition, a circle of elastic notch with a cut towards the top surface is concavely arranged at the top surface of a barrier component close to the external periphery; a clamp stopped flange is convexly arranged at the external periphery of the upper section part of the side end surface of the barrier component to lead the clamp stopped flange on the external periphery of the upper section part of the side end surface to be mutually intercalated with the buckled groove on the lining ring body in the bottle cover body and can withhold a filling second liquid beverage in the hollow containing chamber from leaking outside.

Description

(1) Technical field [0001] The invention relates to a structure capable of preventing leakage of liquid substances in bottle caps, in particular to container bottle caps filled with liquid substances; it belongs to the bottle caps of containers.
