Abstract

The invention provides a novel automatic gas return soft-body cup which comprises a cup body and a cup cover. The cup cover comprises a base. The cup body is a soft cup body capable of being curled. The upper end of the cup body is fixed to the base. The base is provided with a water drinking opening and at least one gas return valves. A valve is arranged in the water drinking opening. Each gas return valve is arranged into a groove shape. Gas return pieces are connected with the backs of the grooves. Vent holes are formed in the bottoms of the grooves. The vent holes are completely covered with the gas return pieces. The gas return valves are arranged, a user squeezes the cup body when needing to drink water, liquid in the cup body flows out of the cup body through the valve in the water drinking opening, negative pressure is formed in the cup body when liquid in the cup body is reduced, external gas enters the cup body through the gas return valves under the effect of the atmosphere, gaps are exposed between the gas return pieces in the cup body under the effect of gas pressure, and then gas can flow into the cup. The novel automatic gas return soft-body cup is simple in structure, automatic gas return is achieved for the cup, daily requirements of users are met, the use experience of the cup is greatly improved, and the novel automatic gas return soft-body cup is greatly popular with users.

Problems solved by technology

[0003] Although the lightweight cup can bring a good user experience, there are still many problems, such as the inability to automatically return air. When the user squeezes out the air inside the cup, the cup will collapse as a whole. Conducive to rapid reuse, there is no good solution to this problem on the market at present, which also greatly restricts the progress of the industry and affects the user experience. Afterwards, automatic air return is realized, which is convenient for users to use quickly. The technicians in this field have carried out a lot of research and development work, and have also designed a better cup structure to solve such problems.
