Abstract: A sliding pull-out tray assembly comprising trays which can be tilted and extended with respect to a supporting shelf structure and which are used for holding and delivering containers, using gravity feed, to the front of the trays. The tray assembly comprises an open-top tray having surrounding walls on the front and sides, and which is mounted on a linear sliding system allowing sliding movement relative to the wire rack shelf to which the tray assembly is attached. By raising the front or lowest end of the tray, the tray assembly may be slid forward so that the rear of the tray may be filled without necessarily disturbing any bottles or cans already present in the front of the tray. The position of the tray apparatus is maintained by fastening the tray apparatus to the back of the supporting wire rack shelf. The pull-out tray assembly may be used as a retrofit in existing refrigerators or refrigeration units by serving as original or replacement shelves.
