Description
Technical Field
[0001] The utility model relates to the technical field of lunch boxes, and more specifically, to an insertion-type multi-compartment flip-cover lunch box. Background Art
[0002] A lunch box is a container for food and is widely used in different scenarios in daily life, making it convenient for people to store and carry food when going out.
[0003] With the accelerated pace of life and the diversification of dietary needs, people have higher and higher requirements for the convenience and functionality of lunch boxes. When traditional single-grid lunch boxes are used to hold a variety of foods, all the foods are placed together, which is prone to problems such as food odor mixing and soup leakage. Although the existing multi-grid lunch boxes have solved the problem of food classification and storage to a certain extent, there are often many inconveniences in the process of taking food. For example, when only one grid of food needs to be taken, it may be necessary to open the lid of the entire lunch box, which will cause the food stored in other grids to be exposed to the external environment, the temperature of the food will drop, affecting the taste of the food, and increasing the risk of food contamination. In the process of carrying it out, the lunch box will tilt or shake. Since the lid of the lunch box is integrated, it is impossible to effectively seal a single grid independently, which will also cause the food in different grids to mix or the soup to overflow, affecting the quality of the food and the eating experience. The existing multiple lunch boxes also have problems such as being difficult to clean after use and poor sealing and leak-proofing effects.
