Abstract

The invention discloses a bottle cap with an inner stopper. The bottle cap comprises an outer cap body and the inner stopper. The inner stopper comprises a stopper pillar with the inside being provided with a cavity. One end of the stopper pillar is connected with a pedestal, and the middle of the other end of the stopper pillar is provided with a columnar protrusion extending to the pedestal. A convex ring used for fixing the columnar protrusion is arranged on the inner wall of the outer cap body. The inner stopper and the outer cap body are fixedly connected. The inner stopper is made of PET, and the sealing effect can be better achieved through elastic contact of the inner stopper and a bottle opening. Moreover, the bottle cap with the inner stopper is simple in structure and high in practicability.

Description

technical field [0001] The present invention relates to wine bottle caps. Background technique [0002] Alcohol is relatively common in people's daily life. If a bottle of wine cannot be finished at one time, it is common to store and drink it again. At present, most of the wine bottle caps on the market do not have inner plugs, but are only separate bottle caps, and the sealing performance is not good. When the wine bottle is opened and needs to be stored again, the wine cannot be tightly sealed and often overflows. There are also some bottle caps with inner plugs, which are sealed with the mouth of the bottle through the plug of the inner plug, but the seal may fail after repeated plugging, and there is a possibility of wine overflowing, especially after multiple uses, the wine bottle The tightness of the lid is worse, and the tightness of the wine bottle lid is not good, which will easily cause the volatilization of alcohol and affect the quality of the wine.
