HEAT INSULATION CASE BODY

摘要

PROBLEM TO BE SOLVED: To provide a compact and rigid heat insulation case body. SOLUTION: In the heat insulation case body 11 obtained by associating an interior finishing case 11a within an external facing case 11b, then injecting to foam a foaming insulator 11c in a space formed between the case 11a and the case 11b and integrating them; the case 11a is constituted of an upper structure A1 made of a resin and having an opening at its bottom, and a bottom structure A2 made of a sheet metal and engaged fixedly from below the bottom of the structure A1 to block the opening of the bottom.
