Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pulp lunch boxes, and more specifically, to a pulp lunch box with a top cover that prevents deformation. Background Art
[0002] In the prior art, there are certain problems in the design of the top cover of the existing pulp lunch box. In particular, the top cover is prone to deformation when it is hit by the outside. This deformation will affect the sealing performance of the lunch box and may even cause the lunch box to be unable to be completely sealed, thereby affecting the safety and hygiene of the food. In addition, the deformation of the top cover will also reduce the stacking stability of the lunch box and reduce its transportation and storage efficiency.
[0003] Existing paper pulp lunch boxes usually do not have internal space separation in structure, resulting in mixed placement of food, which not only affects the taste of the food, but also may cause cross contamination between foods. In addition, since the internal space of the lunch box is not separated, the lunch box cannot accommodate foods with high soup content such as soup, which limits its use scenarios and scope of application.
[0004] Existing pulp lunch boxes have insufficient sealing effects, usually because the sealing performance between the lunch box and the top cover is poor. This insufficient sealing performance will easily allow pollutants such as outside air, dust, and bacteria to enter the lunch box, affecting the hygiene and freshness of the food. At the same time, poor sealing performance will also affect the heat preservation effect of the lunch box, making it difficult to maintain the temperature of the food, affecting the edible quality of the food.
[0005] Existing pulp lunch boxes also have major defects in heat preservation. Generally, the heat preservation effect of pulp lunch boxes is poor and cannot effectively maintain the temperature of food, whether it is refrigerated or hot food. This is mainly because the material and structural design of the lunch box are not conducive to heat retention, which causes the temperature of food to fluctuate easily during transportation and storage, affecting the taste and safety of the food. Therefore, improving the heat preservation effect of pulp lunch boxes is a technical problem that needs to be solved urgently. Utility Model Content
