ABSTRACT:
The insulated door for refrigerators, freezers or similar cabinets where the inner and outer door surfaces are normally subjected to substantially different temperatures. This device has an outer panel with two sides formed by folding up two opposing edges out of its four edges. Two end sections fit on the other two opposing edges of the outer panel in such a way as to close off the above-mentioned two sides. An inner panel is disposed parallel to the outer panel so that its four edges are positioned inside the above-mentioned two sides and two end sections. Insulated material is packed between the said outer and inner panels. The end sections are provided with a first projecting rib and second projecting ribs which grip from both sides in the thickness direction, the edges of the inner panel which are positioned inside the end section. Either protruding or recessed interlocking parts are formed on the first or second ribs, and the corresponding other interlocking parts are formed on the ends of the inner panel. The inner panel and the two end sections are joined by fitting together the protruding and recessed interlocking parts.
