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.

[ I claim:] [1.] A container constructed of corrugated fiberboard for containing fluent materials, comprising:a polygonal tubular outer box;a polygonal tubular inner box having a greater number of sides than the outer box and disposed within the outer box, the sides of the inner box defining a passageway therethrough;a first pair of flaps, one flap of said pair connected to one side of the inner box, the other flap of said pair connected to an opposite side of the inner box, each flap of said pair including an outer free marginal edge;wherein each flap of said pair is foldable over the passageway such that the outer free marginal edge of the first flap of said pair engages the outer free marginal edge of the second flap of said pair when the flaps are folded over the passageway into a closed position, the engaged flaps when in the closed position locking the inner box into a fixed cross sectional shape, each flap of said first pair of flaps also including opposite free side edges, at least one of said opposite free side edges defining a shoulder therealong; andat least one additional flap connected to a side of the inner box and defining an edge that engages said shoulder when said first pair is in the closed position, thereby locking said first pair of flaps in the closed position and preventing said first pair of flaps from moving out of said closed position.
