AI Technical Summary

Technical Problem

Existing screw-top double-walled vacuum cups are limited in their ease of use, and the open mouth makes hot drinks too hot to handle and cannot keep drinks hot or cold.

Method used

Design an open-top double-walled vacuum cup, with a vacuum layer formed between the inner liner and the outer shell. The bottom of the outer shell has a vacuum extraction position and a sealing layer. It is made of metal materials such as stainless steel, aluminum alloy or pure titanium. The cross-section of the outer shell is a circle that is wider at the top and narrower at the bottom to lower the center of gravity.

Benefits of technology

It enables convenient liquid observation and pouring, avoids hand burns, maintains liquid temperature, enhances cup stability and aesthetics, and ensures long-term stability of the vacuum state.

Abstract

The utility model discloses a double-layer vacuum cup which comprises an inner container and an outer shell which are integrally formed, the top of the inner container and the top of the outer shell are connected into a whole, a vacuum layer is formed between the inner container and the outer shell, a vacuum bottom layer is arranged at the bottom of the outer shell, and a vacuumizing position used for pumping air out of the vacuum layer is arranged on the vacuum bottom layer. The vacuum bottom layer is provided with a vacuum solder layer used for blocking the vacuumizing position. A plugging layer is further arranged at the bottom of the shell and located under the vacuum bottom layer; the problems that an existing screw cap type double-layer vacuum cup is limited in use convenience, and a common open cup cannot achieve heat preservation and cold preservation are solved. According to the open type double-layer vacuum cup, due to the fact that the vacuum layer is formed between the inner container and the outer shell, heat transfer is effectively reduced, liquid in the cup can be kept at the temperature for a long time, and the good taste can be maintained whether hot water or cold drink exists. Meanwhile, due to the open design, a user can conveniently clean, pour and observe the liquid, and the use convenience is improved.
