Abstract

The invention discloses a bottle plug. The bottle plug comprises a base and a drum-shaped portion which is arranged on the base through a connection portion, the external diameter of the connection portion is smaller than the maximum external diameter of the drum-shaped portion, a first cavity is formed in the drum-shaped portion, a second cavity is formed in the connection portion, a through hole is formed in the base, and the first cavity, the second cavity and the through hole are communicated. The middle of the bottle plug is small, the two ends of the bottle plug are large, so that after the bottle plug is inserted in a bottle opening, the bottle opening can be sealed firmly, and sealing performance is good; meanwhile, because the first cavity is formed in the drum-shaped portion, the second cavity is formed in the connection portion, the through hole is formed in the base, and the first cavity, the second cavity and the through hole are communicated, when the bottle plug needs to be pulled out, the base is pulled forcefully, the drum-shaped portion is deformed, the size of the first cavity becomes smaller, reduced air in the first cavity is exhausted through the second cavity and the through hole, and the bottle plug can be pulled out. The bottle plug is good in sealing performance and convenient to use.

Description

technical field [0001] The invention relates to an improvement of a bottle stopper, in particular to a bottle stopper with good sealing performance and convenient use. Background technique [0002] In the prior art, a common cork, such as a cork for a thermos bottle, includes a cork body; the cork body is in an inverted conical shape; the cork body is generally made of wooden materials; It will be found that the cork suddenly protrudes from the mouth of the thermos bottle. This is because the pressure in the thermos bottle is too high. Easy-to-use bottle stopper. Contents of the invention [0003] The purpose of the invention is to provide a bottle stopper with good sealing performance and convenient use in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above object, the technical solution adopted in the present invention is: a bottle stopper, comprising a base and a drum; the drum is arranged on the base through a connecting portio...
