Abstract: A corrugated fiberboard bulk shipping container for fluent materials has an outer box and an inner box inserted therein. The outer box is rectangular in cross section, and the inner box comprises two sleeves, each in the form of irregular octagons. During assembly of the container, flaps carried on the outermost of the two inner sleeves fold over the opening at one end of the inner sleeve and engage one another to fix the octagonal shape of the inner box. Extended corner portions on the flaps fit substantially into the outer box and stabilize the inner box within the outer box.

Abstract: A corrugated fibreboard container of tube-and-cap construction has two-walled plastic lining and a bottom side-wall discharge hose. A metal lid-mounting flange in the top end-cap receives a conventional drum lid with vent opening and bung opening threaded to receive a standard plug or a discharge pump fitting to facilitate pumping from the top. A band of reinforcing panels of hardboard mounted on corrugated fibreboard is strapped to the container tube wall and the whole assembly is strapped to a wood pallet for ease of transportation and handling.
