Secure and reliable combined bottle cap and container

Abstract

The invention discloses a secure and reliable combined bottle cap which comprises a base used for connecting a bottle opening and a cover body connected to the base, wherein a reverse buckle I and a limiting boss located above the reverse buckle I are disposed on the base and the limiting boss is disposed on the outer wall of the base; a reverse buckle II is disposed on the cover body; the reversebuckle I can be moved close to the inner wall of the base under pressure of the bottle opening and can prevent the base from being separated from the bottle opening under axial restraining of a raised part of the outer wall of the bottle opening after connection of the base and the bottle opening; and the buckle II can be moved close to the inner wall of the cover body under pressure of the limiting boss and can prevent the cover body from being separated from the base under axial restraining of the limiting boss after connection of the base and the cover body. The combined bottle cap disclosed by the invention has the beneficial effects that the reverse buckles and the limiting boss are disposed on the base to enhance connecting firmness between the base and the bottle opening; the reverse buckles are disposed on the cover body, so connecting firmness between the cover body and the base is enhanced; and in this way, the bottle cap can be prevented from being separated from the bottleopening, and security, reliability and practicability of the container are enhanced.

Description

technical field [0001] The invention belongs to the technical field of container sealing parts, in particular to a safe and reliable combined bottle cap and container. Background technique [0002] The bottle cap is a common sealing part and belongs to one of the components of the container. For a container with a bottle mouth structure, the quality of the connection and sealing of the cap determines the quality of the container. [0003] In the prior art, for food containers such as edible oil barrels and liquid condiment bottles, the bottle caps used for the bottle mouths usually use two opening structures to realize the opening of the bottle mouths. , and then expose the internal pull ring, and then pull the pull ring to completely tear off the cover on the base, so that the bottle mouth is in an open state, and the liquid in the bottle can be poured out through the bottle mouth. When this kind of bottle cap is connected to the bottle mouth, a large pressing force is us...

AI Technical Summary

Problems solved by technology

When this kind of bottle cap is connected to the bottle mouth, a relatively large press-fitting force is used to assemble the bottle cap to the bottle mouth. The firmness of the bottle is poor, and the bottle cap will break away from the bottle mouth when it is subjected to a large pulling force, thereby destroying the safety.
