S樹脂が使われている。2. Description of the Related Art A conventional heat insulating box of a refrigerator will be described with reference to FIG. 2. A heat insulating material 2 such as foamed polyurethane is filled between an inner box 1 and a bottom box 3 made of ABS resin. This inner box is made of AB due to its adhesiveness, chemical resistance to foaming agent,
S resin is used.
発明が解決しようとする問題点 しかし、このようなABS樹脂の真空成形の内箱１はABS

前のシートの厚みを薄くし、かつ変形や割れが発生しな
いようにするには限界があった。Problems to be Solved by the Invention However, such an inner box 1 for vacuum molding of ABS resin is made of ABS.
Because of the high cost of the resin, it was very expensive.
The ABS resin used had a certain degree of rigidity to prevent deformation due to the foaming pressure of the heat insulating material 2 such as foamed polyurethane, and a certain degree of impact strength so as not to break even when the food hit. Even so, if the thickness of the sheet before vacuum forming is only thickened, the inner box 1 may be deformed or cracked, which may degrade the commercial value. Therefore, there is a limit in reducing the thickness of the sheet before vacuum forming and preventing the sheet from being deformed or cracked.
本発明は上記問題点に鑑み安価で強度のある内箱を提
供するものである。The present invention has been made in view of the above problems, and provides an inexpensive and strong inner box.

トの安い、品質の良い断熱箱体が得られる。Therefore, the present invention provides a sheet made of a high-rigidity ABS resin layer containing a low-cost filler such as calcium carbonate and talc in an inner box, and a two-layer ABS resin layer having a high impact resistance and a large amount of comparative rubber. High-rigidity ABS using vacuum molded products
The resin layer is provided on the side of the heat insulating material such as polyurethane foam, the ABS resin layer with high impact resistance is provided inside the cabinet, and the heat insulating material such as polyurethane foam is injected and foamed between the outer box and the inner box. A cheap, high-quality heat-insulated box can be obtained.
