Description

Portable lunch box with thermal insulation function

Technical Field

The utility model relates to a food container technical field, concretely relates to heat preservation and portable lunch box.

Background

The lunch box is also called lunch box, which is a box body specially used for holding food, and is mostly made of materials such as aluminum, stainless steel, plastics, etc. The lunch box in the early stage relies on the grafting of lid in the box body upper end to realize the closure effect, can not realize sealed effect yet, can't realize also that the lid is fixed on the box body, consequently turns over to spill, oozes phenomenons such as hot water in carrying the in-process very easily to appear. In recent years, along with the continuous development of the technology, the sealing performance of the lunch box has made a great progress, and the box cover with the flanging at the edge is clamped and buckled with the convex edge at the edge of the upper end of the box body (commonly called a Lexuan lunch box), so that the sealing of the box body can be effectively ensured, and the liquid seepage phenomenon can be avoided. Such products are now very common in the market, making the carrying of the lunch box more convenient.

Although outstanding improvements are made in the aspects of sealing performance, portability and the like, the lunch box is still generally used for containing food at present, and the structure of the lunch box is inconvenient for drinking by mouth, so that the lunch box is difficult to be used as a water container at present. Under such circumstances, if a lunch box convenient for drinking can be developed, it is expected that the use function of the conventional lunch box will be expanded. In addition, the conventional lunch box is inconvenient for keeping the temperature or heating the contents, and when devices such as a rice steaming box and a microwave oven are lacked in the using environment, how to keep the temperature and heat the food in the lunch box becomes a technical problem to be solved urgently.
