It mainly uses some insulating materials to reduce the transfer of heat, thereby keeping the temperature of the food for a longer time. Existing disposable insulated lunch boxes are generally composed of a lunch box body and an upper cover. The box body is used to hold food, and the upper cover mainly plays a sealing role, thereby playing a role of sealing and heat preservation for the food placed in the box body;

[0003] With respect to the above-mentioned related technologies, the inventor believes that the conventional upper cover generally can only play a role in sealing and keeping the food in the box warm. When diners eat the food in the box, since the food may contain residues or bones of other foods, or there is a lot of soup inside, when they want to pour out the excess soup inside and fish out the food at the bottom, for convenience, diners generally place or pour the residues, bones, soup, etc. on the upper cover. However, the capacity of the upper cover is generally relatively limited. If a lot of soup is poured in, it may overflow, which may be relatively inconvenient to use.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.
