ABSTRACT:
A double wall corrugated bulk material shipping container is provided with a dispensing opening in the depending end portion of one of its walls. Intersecting edge surfaces of the wall forming the dispensing opening are formed on a radius to prevent rupture of the container wall by the mass of contained bulk material when the opening is uncovered. The opening is covered and the container wall surface surrounding the opening is shielded from contamination during shipping or storage by a removable door cover overlapping the container wall having the opening and adjacent surfaces of adjoining walls. The door cover is maintained in place by container surrounding bands.
