A metal transport pan having front, rear and end side walls extending downwardly with a slight inward taper and which are joined at curved corners, the lower parts of which have a similar taper and a top flange extending outwardly from the top of the side walls. Each of the curved corners has a nontapered section extending downwardly from the top flange generally at a right angle thereto to provide an outwardly protruding ridge whereby the spaced-apart ridges define a plurality of nesting surfaces for engagement with the top flange of a subjacent pan to limit the extent to which one pan may nest into the other and prevent contact between the side walls of the nested pans to maintain the stacked pans in nonjamming relation. The nontapered sections of the curved corners are formed at the same time as a conventional pan-forming draw is being performed in order to avoid any additional manufacturing steps. |
