Abstract
Abstract A tray is provided of two tray sections. The bottom portion comprises a rectangular bottom panel, side and end walls extending upwardly therefrom, and corner flaps hinged to the end walls and secured in face contact with the side walls. The other portion telescopes over the bottom portion and includes a top portion and side and end walls, the end walls being provided with corner flaps secured in face contact with the side walls. The trays are impregnated with a wax containing coating and are very rigid. The top of the top portion is cut to provide end wall liner panels, and the corner flaps extend the full height of the side walls to reinforce the corners.
