Abstract
A molded paper pulp container comprising a pocketed section mutually hinged to a flat bottom cover section, both said sections comprising tapered walls bordering on said hinge, the external surfaces of said tapered walls bordering on said hinge comprising projecting abutting elements cooperating together to limit the inverted folding around said hinge. The molded paper pulp containers, mainly egg cartons, may be stacked in their flat open condition with the bottoms of the cover sections of a number of stacked containers maintained parallel thus allowing easy unstacking by mechanical devices such as suction-cups equipped unstackers.
