Abstract: A three-position stacking tray having a series of angled ribs on each side of the tray which comprise the tray's sidewalls. Each sidewall's ribs are all parallel one to the other, are of identical structure and size, and are all in a common vertical plane relative to the floor. The angled ribs of one sidewall are disposed in mirror relation with the angled ribs of the other sidewall as to orientation and position. Each rib of each sidewall's angled ribs, on the same side edges thereof and intermediate the top and bottom ends thereof, is provided with a notched middle seat adapted to cooperate with a top seat on an opposite sidewall rib's top end when the trays are reverse oriented. In the intermediate stack position, and with upper and lower trays reverse oriented, the top end seats of the lower tray's angled ribs engage the notched middle seats defined in the upper tray's angled ribs.

Abstract: A multi-tray basket that includes a plurality of trays, and a one-piece basket frame comprised of opposed side walls connected together by a floor. The trays each include downwardly depending lips adapted to seat on shelf rails molded integral with the basket's side walls. Each tray's lips cooperate with front and rear stops on each shelf rail to prevent forward/rearward motion of the tray on the rail once the tray is seated thereon. Each tray's lips also cooperate with lateral stops on the upper shelf rails to prevent lateral spreading of the side walls where the basket is loaded. Each side wall includes a stacking rib along the top edge thereof, and includes a stacking rail along the bottom edge thereof. A first basket's stacking ribs are adapted to interfit with a second basket's stacking rails so that successive baskets may be stacked and retained one on top the other by the interfit of the stacking ribs and the stacking rails.

Abstract: 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 extending 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.

Abstract: A unitary molded plastic tray which is stackable for purposes of transporting bakery goods and the like therein and which is nestable for purposes of empty tray storage. The tray has two opposed high profile end walls and two low profile side walls as well as a bottom made from a grid of intersecting ribs. The tray is so configurated that like trays may be stacked one upon the other when similarly oriented and may be nested one within the other when one tray is rotated 90.degree. with respect to the other. The gridwork of bottom ribs are generally T-shaped in cross sectional configuration and extend diagonally across the bottom at an angle of approximately 45.degree. to the side and end walls so that the bottom structure resists torsional deflection under uneven loading conditions as well as vertical deflection from excessively heavy loads.
