ABSTRACT:
A collapsible container includes opposed side walls hingedly connected along their upper and lower edges respectively to the bottom of a rectangular peripheral upper rim and to the bottom of the container along opposed side edges of the rim and bottom. End walls are hingedly connected along their upper edges to the rim along its opposed end edges. Webs along the end edges of the side walls and bottom engage the end walls to locate the end walls in their vertical erected position relative to the bottom, and projecting tabs on the end walls are received in mating recesses in the web to maintain the bottom and side walls against flexing when the container is erected. The upper rim is adapted to receive a stacking rail formed on the container bottom to enable stacking of the containers either in their erected or collapsed configuration.
The container may include a pair of cover panels hinged along their respective outer side edges to the tops of the side edges of the rim. The end edges of the cover panels are formed with rim receiving grooves on their lower sides which snugly receive the end edges of the rim when the cover panels are closed. The cover panels are formed with a stacking rail receiving recess in their upper surfaces.
