Bottle cap and bottle plug capable of realizing automatic pressure relief

Abstract

The invention discloses a bottle cap capable of realizing automatic pressure relief. A pressure relief cut is formed in a circular connection part of a pressure relief structure, and meanwhile, a conical connection part is extruded through a tubular connection part A (tubular connection part B), and then the pressure relief cut is enabled to keep a sealed state, so that the case that the sealing performance of the bottle cap is influenced because the pressure relief cut is deformed due to long-time use, can be avoided; and the advantages of simple structure, and good sealing effect and pressure relief effect are achieved. The invention further discloses a bottle plug capable of realizing automatic pressure relief. A sealing part is arranged on an exhaust channel of a bottle plug body, a pressure relief cut is formed in the sealing part, and interference fit is adopted for the bottle plug body and a bottle opening of a container, and therefore, the bottle opening of the container is capable of extruding the sealing part, and then the pressure relief cut is enabled to keep a sealed state, so that the case that the sealing performance of the bottle plug is influenced because the pressure relief cut is deformed due to long-time use, can be avoided; and the advantages of simple structure, and good sealing effect and pressure relief effect are achieved.

Description

【Technical field】 [0001] The invention relates to a bottle cap capable of automatically releasing pressure, and also relates to a bottle stopper capable of automatically releasing pressure. 【Background technique】 [0002] In the prior art, there are many containers that are used for fermentation or contain pressure. When the container is fermenting, it will continuously generate gas. With the increase of gas, the pressure of the container will increase. At this time, the pressure gas in the container needs to be released so that the container can work normally. There are two ways to release it. One is to manually open the lid, which is time-consuming and laborious, and it is difficult to grasp the time. There will also be a great safety hazard when the high-pressure gas in the container is released. 【Content of invention】 [0003] In order to solve the above technical problems, the present invention provides a bottle cap capable of automatic pressure relief, comprising a ...
