1. A disposable container, comprising containerboard for folding between a relatively flat configuration for storage thereof and a set-up configuration for receiving articles therein, said container including a bottom wall, a pair of opposing side walls foldably attached along respective proximal edges thereof to said bottom wall, a pair of opposing end walls foldably attached along respective proximal edges thereof to said bottom wall and respectively interposed between said side walls about the periphery of said bottom wall, four pairs of gusset pleats interconnecting adjacent edges of adjacent side and end walls so as to form a seamless container interior portion whenever said end and side walls are raised into set-up configuration respectively perpendicular to said bottom wall, at least one top wall foldably attached to a distal edge of one of said end walls for closing said container interior, handle means associated with said at least one top wall for carrying of said disposable container, at least one first wall locking member received on each respective distal edge of said side walls, and at least one second wall locking member respectively operatively and removably associated with each first wall locking member in linear surface contact therewith for reversibly holding said container in said set-up configuration thereof, each said second wall locking member being associated with one of said end walls and a pair of said gusset pleats interconnecting said end wall and said side walls associated therewith;

  • said container further including top closure locking means for positive locking closure of said container interior, w herein said top closure locking means includesplanar slots formed between said side walls and adjacent gusset pleats whenever said container is in said set-up configuration thereof, and with longitudinal slotted openings thereto;

    two top walls foldably attached along respective proximal edges thereof to respective distal edges of said end walls;

    a locking panel attached to a distal edge of one of said top walls so as to extend down at least a part of the exterior of an opposite end wall whenever said container is in said set-up configuration thereof and said top wall are folded inwardly across the top of said container interior so as to close same; and

    a pair of locking tabs carried respectively on opposite lateral edges of said locking panel so as to be received in respective of said planar slots passed through said slotted openings thereto, such that said locking panel becomes positively locked with said one top wall across said top of said container interior so as to foldably form a self-locking closable container.
