Abstract: Metal or plastic ice cube trays have flat lids hinged along one edge to facilitate emptying ice cubes in an orderly manner when the tray is inverted and held under running water. The trays are stackable and have support legs of sufficient length to hold the ice cube compartments of each tray spaced from the lid of the next underlying tray to avoid a freezing bond between trays. The tray lids have corner notches which receive and help to position said legs when the trays are stacked.
