ABSTRACT:
A fast food serving tray has the shape of a ship or boat. It is formed from a partly assembled, knocked down structure formed from an integral, single blank of cardboard or the like. The pre-assembled arrangement has the sides of the boat structure flat and co-planar with each other. The side walls are preferably adhesively secured to each other at each end of the tray. When the side walls are spread apart to form the rounded shape of a ship bowl, a folded bottom wall is brought into a planar relationship forming a reinforcement at the bottom edges of the side walls. Two generally circular openings are formed on top of the tray together with a relatively large rectangular central opening which is reinforced by a pair of inwardly turned rectangular panels, one at each side of the tray. The advance in the art is in an improved sturdiness and an ease of assembly.
