Abstract: A unitary bulk container is described having an inner sleeve (10) and an outer sleeve (12). The inner sleeve (10) has opposed side panels (22), (24) and two sets of opposed end panels. The outer sleeve (12) has opposed side panels (62), (66) and opposed end panels (60), (64). As assembled, the inner sleeve (10) is positioned within the outer sleeve (12) with either the inner sleeve side or end panels being adhered to the outer sleeve side or end panels. The other of the inner and outer sleeve side or end panels are not adhered to one another. The outer sleeve (12) of the assembled container preferably has a four-sided shaped, though at least two of its upright corners do not form true 90 degree angles. The container is capable of assuming a flat unitary collapsed state and an open unitary erected state. The container is initially formed to its flat unitary collapsed state.
