New bottle cap

Abstract

A new bottle cap comprising a cap body and at least one air-return valve having a drinking port and an air-return port which is correspondingly disposed to the air-return valve are disposed on the cap body; an anti-leakage valve is disposed in the drinking port; the place where the air-return port is located extends inwardly to form a convex portion in the cap body; one end of the air-return valve is connected to the convex portion in a matching way, and the other end of the air-return valve is a closed port structure; one end of the air-return valve is designed to be a closed port structure, which can effectively prevent the air in the cap body from outflowing through the air-return valve.

Description

TECHNICAL FIELD OF THE INVENTION[0001]The present invention relates to the technical field of bottle structures, and more particularly, to a new bottle cap having a simple structure and a dismountable air-return valve, which can realize an automatic air-return.BACKGROUND OF THE INVENTION[0002]With the improvement of living standards, people are demanding higher quality and practicability of everyday items (e.g., a bottle). As more and more people enjoy travel and physical exercises nowadays, various portable bottles made of soft materials are appeared on the market. Although the soft bottle can provide a good experience to the users, and satisfy their daily needs due to its lightweight and portability, the traditional soft bottle also has some shortcomings.[0003]In the prior art, when the air in the soft bottle is squeezed out by the user, the whole body of the bottle can become deflated, resulting in a difficult reuse for the user.

AI Technical Summary

Benefits of technology

The present invention is a new bottle cap with a dismountable air-return valve that can automatically return air. The cap has a closed port structure that prevents air from escaping through the valve, and allows air to flow into the cap from outside when the air pressure is higher than inside. This cap has a simple structure and provides a convenient and stable experience for the user.

Problems solved by technology

In the prior art, when the air in the soft bottle is squeezed out by the user, the whole body of the bottle can become deflated, resulting in a difficult reuse for the user.

Although lots of studies have done, there is no solution capable of solving this problem, which seriously restricts the development of the industry, and greatly impacts the experience of the users.

In conclusion, the shortcomings of traditional soft bottle are urgent problems need to be solved for those skilled in this field.
