Abstract: This invention is directed to a vacuum metallizing process and, particularly, to an improved process for applying thin chromium coatings to the surface of both rigid and flexible plastic articles. The method includes securing a high purity chromium bar between spaced electrodes, mounting the articles to be coated in proximity to the bar, passing an electric current directly through the bar sufficient to evaporate chromium from the surface thereof, and condensing the evaporated metal on the surface of the plastic articles. The method is carried out at a subatmospheric pressure in the range of 2 to 5.times.10.sup.-5 mm Hg. Articles made in accordance with the method disclosed possess an adherent bright, reflective chromium film of a thickness in the range of about 800 to 1000 A.

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.
