Description

A dust-proof twist-resistant plastic bottle cap

technical field

The utility model relates to the technical field of bottle caps, in particular to a dustproof and twist-resistant plastic bottle cap.

Background technique

Bottle caps are used for sealing bottles and lottery activities of merchants. According to different functions, there are bottle caps with different shapes and different operation methods.

When the existing plastic bottle needs to use a straw, because the gap between the straw and the mouth of the bottle is too large, it is easy to cause dust to enter. For example, the authorized announcement number is a dust-proof plastic bottle cap disclosed by CN211811081U. The diameter of the second internal thread port is close to the diameter of the straw, thereby preventing external dust from entering the inside of the bottle mouth, but it does not solve the problems of weak twist resistance of the existing handle and easy loss of the bottle cap. We propose a dust-proof twist-resistant plastic bottle cap.
