Bottle cap

Abstract

The invention discloses a bottle cap which comprises a cap body and an anti-theft ring. The anti-theft ring is connected to the lower portion of the cap body through a connecting bridge. Double annular inner plugs are arranged at the top of the inner wall of the cap body. When the double annular inner plugs and a bottle opening are twisted together, the inner surfaces of the double inner plugs areclosely attached to the inner side and the outer side of the bottle opening; and the anti-theft ring is provided with an annular inner buckle concentric with the anti-theft ring, and a plurality of protruding blades which are cut off in a segmented mode and annularly distributed serve as the annular inner buckle. By using the bottle cap, liquid leakage can be effectively prevented, and the stable, high-speed and efficient ideal effects are achieved in production and use.

Description

technical field [0001] The invention relates to a bottle cap, in particular to a double inner stopper type bottle cap. Background technique [0002] In the prior art, for small-sized liquid bottle-shaped packaging materials, it often occurs that the connection between the bottle and the cap is not tight, which leads to problems such as easy leakage and easy contamination of the liquid. For single-screw caps, after filling, it takes 1 second to tighten the cap, resulting in low filling efficiency. [0003] In the traditional craft design, the anti-theft ring of the cap adopts twisted teeth design. The disadvantage of this design is that after the cap is unscrewed, the twisted teeth of the anti-theft ring do not fit tightly with the contact part of the bottle, and it is easy to bring out the anti-theft ring. , affecting the quality of the product. In order to solve this problem, the designer improved the molding scheme of the product, and added a ring-shaped inner buckle to ...

AI Technical Summary

Problems solved by technology

However, this solution still has the problem of not being tightly connected between the bottle and the cap for small liquid bottles, which leads to problems such as easy leakage and pollution of the liquid, and the traditional ring-shaped inner buckle is easy to lock the mold core and cannot be demoulded.
