Description

Technical Field

[0001] The utility model relates to the technical field of lunch boxes, in particular to an easy-to-clean double-layer lunch box. Background Art

[0002] Nowadays, the pace of life is accelerating, and people often bring meals in lunch boxes, such as when going to school, work or traveling. Compared with disposable lunch boxes, lunch boxes are safer and more hygienic, and multiple use is also more environmentally friendly. They are generally divided into two layers, and different foods can be placed at the same time. They need to be easy to carry when going to school, work or traveling, and convenient for people to use multiple times. Therefore, they need to be cleaned in time after use to facilitate the next use.

[0003] Because this type of lunch box is reused many times, during the cleaning process, corresponding slots are usually set at the connection point where the upper and lower lunch boxes are engaged. Although such a slot design facilitates the upper and lower layers to be firmly connected together, it is also easy to leave a lot of extremely fine food residues and dirt. When cleaning, these dirts are easy to accumulate and are easily ignored by people. Then, after a long period of accumulation, it will form dirt residues that are difficult to remove, which is extremely detrimental to the health and safety of the eater. Utility Model Content
