Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a food packaging container. Background Art

[0002] Food packaging containers play a vital role in the food industry, not only protecting food from external contamination and physical damage, but also extending the shelf life of food and improving the safety and hygiene level of food. With the development of the food industry and the increasing demand of consumers for food safety and convenience, food packaging containers are also constantly innovating and improving.

[0003] After searching, the existing patent (Announcement No.: CN213096631U) discloses a lunch box, including an upper box body and a lower box body, the upper box body is assembled above the lower box body, one of the bottom of the upper box body and the top of the lower box body is provided with a first assembly edge, the other of the bottom of the upper box body and the top of the lower box body is provided with a second assembly edge and a first limiting protrusion, the first limiting protrusion and the second assembly edge are arranged at intervals, and the first assembly edge can be inserted between the first limiting protrusion and the second assembly edge. Due to the arrangement of the first limiting protrusion, the lunch box provided by the utility model can easily insert the first assembly edge between the first limiting protrusion and the second assembly edge to complete the assembly even if the lunch box is deformed to a certain extent. Therefore, the requirements for shaping treatment during the processing are relatively low, shaping labor can be saved, production efficiency can be improved, and product quality can be improved.

[0004] Traditional food packaging containers mainly include plastic boxes, glass bottles, metal cans, etc. They can meet the basic needs of food packaging to a certain extent, but they also have some shortcomings, such as poor sealing performance, difficult to clean, and environmentally unfriendly. Therefore, more and more food packaging container designers and manufacturers have begun to devote themselves to developing new food packaging containers with better performance. However, in the above scheme, during actual use, the lock buckle and the lock convex fix the upper box body and the lower box body, but the lock buckle and the lock convex will wear each other during long-term use, resulting in loose fixation, which affects subsequent use.

[0005] In view of this, the utility model provides a food packaging container. Utility Model Content
