[0002] In the current social context of increasing environmental awareness, high-strength, anti-deformation environmentally friendly pulp molded lunch boxes are increasingly valued due to their renewable and degradable properties. However, in actual application, this type of lunch box has a significant technical problem: since most of its designs are flat, when heavy objects are placed or pressure is applied, the lunch box is subjected to greater forces in the vertical direction. In this case, the existing lunch box structure often cannot be effectively strengthened to resist deformation caused by external forces. This undoubtedly has a certain impact on the safety of the lunch box, especially when it is used to hold hot food or heavy food, users have higher expectations for the stability of the lunch box.

[0003] In response to this problem, the existing high-strength, anti-deformation, environmentally friendly pulp molded lunch boxes need to be improved in terms of structural design. Because the lunch boxes are easily deformed or even broken when subjected to large vertical forces, this limits the use of the lunch boxes and requires consumers to be extra careful when using them to prevent accidents.
