Description

technical field [0001] The invention relates to a container, in particular to a waterproof bag which can be insulated and has a locking unit. Background technique [0002] refer to figure 1 The thermal insulation and waterproof bag 1 currently on the market includes a foam inner pad 11, an outer cover 12 covering the foam inner pad 11, an outer cover 13 partially connected to the outer cover 12, and an outer cover 13 wrapped around the outer cover 13. The inner foam lining 14, and a zipper 15 connecting the outer cover 12 and the outer cover 13. [0003] Through the inner foam pad 11 and the foam inner lining 14, the waterproof bag 1 can achieve heat insulation and prevent moisture from entering and leaving. However, the foam inner pad 11 and the foam inner liner 14 are not completely sealed, and the foam inner pad 11, the outer cover 12, the outer cover 13, and the foam inner liner 14 are all soft materials , so it is easy to deform under pressure to form a gap between t...

Problems solved by technology

However, the foam inner pad 11 and the foam inner liner 14 are not completely sealed, and the foam inner pad 11, the outer cover 12, the outer cover 13, and the foam inner liner 14 are all soft materials , so it is easy to deform under pressure to form a gap between the outer cover 12 and the outer cover 13, causing moisture and heat to escape or enter through the aforementioned gap and the zipper 15, reducing heat insulation and waterproof performance. In addition, the path of the zipper 15 is usually Around the setting, it is not smooth at the corner when opening, which affects the user experience, and it is easy to fall off and damage under long-term stress
