IMPROVED TRAY STRUCTURE Abstract of the Disclosure An improved square tray structure in which a series of trays can be stacked one on top another when the trays are loaded, and which can be nested one within another when the trays are empty. The tray's end walls are of a height about one-half that of the tray's side walls, the end and side walls all extending up from the tray's floor. The tray's floor is positioned closely adjacent the tray's bottom edges. The tray's side walls each include a top rail and a top rib extending along the top edge thereof, and a bottom rail extending along the bottom edge thereof, the rails and rib being linear and ex- tending from adjacent one end to the other of the side wall. The tray's end walls each include a middle rail and a middle rib extending along the top edge thereof from adjacent one end to the other of the end wall. In use, and when the trays are stacked, the trays' side walls are oriented into a vertical coplanar attitude so that a bottom rail of an upper tray seats on a top rib and rail of a lower tray on each side thereof for supporting the trays in that stacked relation. When the trays are nested, the upper tray is rotated 90° relative to the lower tray so that the upper tray's bottom rails seat on the lower tray's middle ribs and rails, and so that the upper tray's middle rails seat on the lower tray's upper ribs and rails, for supporting the trays in that nested relation. The top, middle and bottom rib and rail structures cooperate with the trays' walls to prevent end-to-end, as well as side-to-side, movement of the upper tray relative to the lower tray when the trays are in stacked, as well as in nested, relationship with one another.
