DETAILED DESCRIPTION

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0023] The following is in conjunction with the appendix Figs. 1 to 4 To further describe, this utility model discloses a heatable and heat-insulating folding lunch box, including a silicone box body 1, a lunch box lid 2 disposed on the silicone box body 1, and a vent cover 3 disposed on the lunch box lid 2. The silicone box body 1 includes a first folding layer 10, a second folding layer 11, and a third folding layer 12 from top to bottom. The second folding layer 11 can be folded into the first folding layer 10 by pressing the silicone box body 1, and the third folding layer 12 can be folded into the second folding layer 11. The silicone box body 1 is folded up by the deformation of the silicone to reduce its volume and storage space. A mounting groove 16 is provided on the side of the third folding layer 12. A control board cover 4 is installed in the mounting groove 16. The control board cover 4 is connected to a circuit board 6 and a heating tube 7 disposed in the third folding layer 12.
