ABSTRACT:
A fast food containing and serving device comprising a thin wall structure erected from a paperboard blank so as to be movable (1) from a tray defining position wherein the same can be stored in a stacked nested relationship with a multiplicity of similar thin wall structures into a closed container defining position wherein fast food or the like can be contained therein and (2) from the closed container defining position back into a tray defining position wherein the same can be used in serving the fast food or the like contained therein. The movement of the thin wall structure between the tray defining position and the closed container defining position is facilitated by a pair of spaced fold lines extending in the central portion of the flat bottom wall thereof between the central portions of the associated pair of side walls thereof and four cooperating fold lines in the central portions of each side wall. The thin wall structure when in the closed container defining position is folded along the pair of spaced fold lines and four cooperating fold lines of each side wall to generally enclose a fast food containing space encompassed (1) at its bottom by an end portion of the bottom wall, (2) at its top by an opposite end portion of the bottom wall and (3) peripherally by the end and side walls and a central portion of the bottom wall. Each set of four cooperating fold lines forms an outwardly folding locking flap operable to be hinged into a contiguous exterior locking position and releasably retained therein to thereby releasably retain the thin wall structure in its closed container defining position.
