Description

Technical Field

[0001] The utility model belongs to the technical field of heat preservation lunch boxes, and particularly relates to a heat and cold separated heat preservation lunch box. Background Art

[0002] Existing heat preservation lunch boxes generally include an external stainless steel heat preservation shell, and also include several small boxes for containing meals. The several small boxes are placed in the stainless steel heat preservation shell, and the meals in the small boxes are heat-preserved by the external stainless steel heat preservation shell. The defect of this kind of heat preservation lunch box is that the meals placed in the general small boxes are all hot foods, that is, the stainless steel heat preservation shell mainly plays a role in keeping heat. When cold foods such as cold dishes need to be carried, if the small box containing cold dishes is stacked with other small boxes, as the temperature in the stainless steel heat preservation shell rises, it will eventually inevitably affect the taste of the cold dishes. Therefore, it is necessary to design a heat preservation food box in which hot foods and cold foods are placed separately. Content of the Utility Model
