<p>Provided is a thermally insulated case, comprising a case body (1) and a case cover (2), wherein an opening (6) is provided on a surface of the case body, the opening is sealed by the case cover, and the case body and the case cover comprise a first thermally insulating layer (3), a second thermally insulating layer (4) and a housing (5). The first thermally insulating layer, the second thermally insulating layer and the housing are adjacent to one another successively from inside to outside, the first thermally insulating layer is a vacuumed thermally insulating plate, and the second thermally insulating layer is a foamed polyurethane plate. The structure of the thermally insulating case according to the present invention can insulate from most heat in the outside environment, and maintain the temperature in the case at 2°C - 8°C for more than 120 hours.</p> |
