Bottle cap

Abstract

The invention provides a bottle cap. A sliding groove is formed in the outer top surface in the radial direction, and a tool bit base is slidably connected in the sliding groove; and inward convex edges are arranged at the top ends of the two side walls of the sliding groove, sawteeth are arranged at the bottoms of the convex edges, latches matched with the sawteeth are arranged on the two sides of the top of the tool bit base, a tool bit is fixedly connected to the middle of the top of the tool bit base, the tool bit is in a cone type, and the conical tip faces upwards. By arranging the sliding groove in the outer top surface, the tool bit base and the sliding groove slide through the cooperation of the sawteeth and the latches, so that different positions of the tool bit are adjusted, the purpose of gashing sealing films with different opening diameters is achieved, and different ages of consumer groups are facilitated; and the bottle cap is simple in structure, convenient to machine and boarder in application range.

Description

technical field [0001] The invention relates to a bottle cap, in particular to a bottle cap capable of scratching different calibers. Background technique [0002] At present, when some beverage bottles, baby bottles, medicine bottles, etc. are in use, in order to avoid the internal contact with the outside air and prolong the shelf life of the product, a sealing film is often pasted on the bottle mouth. The sealing film includes aluminum film, plastic film, paper film, etc., people need to tear off the sealing film before drinking or using. [0003] There are two ways to separate the sealing film. One is to use an easy-to-tear sealing film and tear it off directly when drinking; the other is to use a single opening tooth on the bottle cap. Separate the parafilm from the neck of the bottle. [0004] The above two methods have certain disadvantages. The easy-to-tear film requires a large external force to tear it, and sometimes there is a phenomenon that it is difficult to ...

AI Technical Summary

Problems solved by technology

[0004] The above two methods have certain disadvantages. The easy-to-tear film requires a large external force to tear it, and sometimes there is a phenomenon that it is difficult to open or the sealing film remains on the bottle mouth; the cap with a single opening can only be screwed clockwise. It is inconvenient for consumers, and the size of the sealing film cut by a single opening tooth can only be fixed to one type, and it is impossible to provide humanized services for different consumers
