ABSTRACT:
A box constituting heat insulating walls of a refrigerator or freezer cabinet, wherein the walls are formed by an inner shell of metal, an outer shell of metal, and an evacuated heat insulation between the shells. The shells provide edges which surround a rectangular access opening to the box and which are folded towards each other so that they form planar surfaces located in substantially the same plane. The planar surfaces are gas-imperviously connected to each other by a thin metal strip having poor heat conductivity. The strip is soldered to the planar surfaces.
