发明名称 Door for refrigerator and method for manufacturing the same, metal container and method for manufacturing the same, and apparatus and method for processing metal sheet
摘要 Provided is a door for a refrigerator. The door includes an outer door manufactured by pressing and deforming a metal sheet. The outer door includes a first surface, second to fifth surfaces extending from the first surface, and a plurality of flanges extending from the second to fifth surfaces. The first to fifth surfaces are integrated with each other and defined based on the pressing and deforming of the metal sheet. A door liner is coupled to surfaces of the plurality of flanges of the outer door, and an insulation material is disposed in a space defined between the door liner and the outer door.
