[0002] A travel mug is a type of cup designed for travel, typically featuring multiple functions such as portability, leak-proof design, and insulation, aiming to enhance the drinking experience during journeys. Using a travel mug reduces reliance on disposable plastic cups, contributing to environmental protection and reducing waste. Travelers can use their own travel mugs in hotels, restaurants, or public places, making it both convenient and environmentally friendly. Portability is a crucial criterion for a travel mug; however, most travel mugs on the market are currently made of stainless steel, which has a fixed size and takes up considerable space when carried.

[0003] Therefore, some people have designed water cups with folding functions to improve portability. For example, Chinese utility model patent application CN207202448U discloses a portable folding water cup, which includes: a cup body, and a matching cup lid and handle. One side wall of the cup body is a concave arc surface; the handle is a rotatable arc-shaped movable handle; the arc-shaped movable handle is installed on the concave arc surface of the cup body; rotating the arc-shaped movable handle allows it to switch between the inner and outer areas of the concave arc surface, thus putting the arc-shaped movable handle into a storage or use state; when the arc-shaped movable handle is in the storage state, its outer arc surface fits against the concave arc surface of the cup body and makes elastic contact with the concave arc surface. The handle can fit snugly against the cup body, and after exercise, when hands are sweaty, the handle can be pulled out, preventing the water cup from slipping and falling.

[0004] However, this existing structure still has the following shortcomings:

[0005] In this technical solution, the curved handle is folded and stored in the concave arc surface on the cup body to avoid the concave arc surface.
