Problems solved by technology

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 labor-intensive, and it is not easy to control the time. When the high-pressure gas in the container is released, there will be a great safety hazard

Embodiment 1

[0039] Such as figure 1 and figure 2 As shown, a bottle cap with automatic pressure relief in Embodiment 1 includes a base 1 connected to the opening of the container and an upper cover 2 connected to the base 1, and the outer side of the upper cover 2 is threaded on the base 1 Above, the base 1 is provided with a pressure relief structure 3, the pressure relief structure 3 is a trumpet-shaped structure with a small upper end and a larger lower end, and includes a conical connecting portion 31 and a circle connected to the upper end of the conical connecting portion 31. Shaped connecting portion 32, the circular connecting portion 32 is provided with a pressure relief slit 33 connecting the inner cavity of the container and the outside world, the pressure relief slit is to use a sharp knife to cut a hole on the circular connecting portion 32, When the pressure in the container is small, the pressure relief notch remains sealed. When the pressure of the container exceeds a ce...

Embodiment 2

[0041] Such as image 3 As shown, the difference between Embodiment 2 and Embodiment 1 is that on the basis of Embodiment 1, an upwardly arched curved transition portion 321 is provided at the circular connection portion 32 and at the pressure relief slit 33, so The above-mentioned pressure relief slit 33 is arranged on the top of the curved transition portion 321 so that the pressure relief slit 33 remains in a sealed state; Provide greater extrusion force and improve the sealing effect of the pressure relief notch 33 .

Embodiment 3

[0043] Such as Figure 4As shown, a bottle cap that can automatically release pressure in embodiment 3 includes a base 1 connected to the opening of the container and an upper cover 2 connected to the base 1, and the outer side of the upper cover 2 is threaded on the base 1 Above, the upper cover 2 is provided with a pressure relief structure 3, the pressure relief structure 3 is a trumpet-shaped structure with a large upper end and a smaller lower end, and includes a conical connecting portion 31 and a conical connecting portion 31 connected to the lower end. Circular connecting portion 32, said circular connecting portion 32 is provided with a pressure relief slit 33 connecting the inner cavity of the container with the outside world, and the pressure relieving slit is to use a sharp knife to cut a hole on the circular connecting portion 32 When the pressure in the container is small, the pressure relief notch remains sealed. When the pressure in the container exceeds a cert...

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 ...
