ABSTRACT:
A container formed from a blank of corrugated paperboard in which scores define a plurality of wall panels and bottom flaps. Two opposing bottom flaps overlap opposing sides and interlock together in a notch on a distal edge of one of the bottom flaps, whereby the container substantially maintains a squared-open configuration for inverting the container bottom-down on a pallet, with reduced manpower and effort on a production line.
