Disposable container assembly for liquids or semi-liquids in bulk

The method of packaging bulk material in a disposable fiberboard container assembly which comprises:

• providing a pallet which has a support surface, setting up on the support surface a bottom tray from a flat blank of fiberboard or the like by turning upwardly flanges hinged to the polygonal periphery of a flat disc-like bottom at horizontal hinge joints, applying at least one tie-band to hold such flanges in upstanding position, setting up from a flat blank a tubular body of fiberboard or the like composed of a plurality of panels hinged together at vertical joints to form a multi-side polygonal body open at both its upper and lower ends and having panels corresponding in number and position to the upstanding flanges of the tray so it is of complemental polygonal form and inserting its lower end downwardly into the tray with its panels in face contact with corresponding upright flanges of the tray and with the lower end of the body resting on the disc-like bottom of the tray, placing a flexible bag in the body of the tray and supplying it with the desired contents, closing the upper end of the bag, placing a compression-receiving spacer above the upper end of the bag, but filling the bag before applying the spacer to such an extent and closing it so that there is a void in the body between the closed upper end of the bag and the flat disc-like top of the cap for receiving the spacer and positioning a pressure-applying disc on the bag and upon which the spacer is supported, setting up a cap from a flat blank of fiberboard or the like by turning downwardly flanges hinged to the polygonal periphery of a flat disc-like top wall, the polygonal periphery corresponding to the polygonal shape of the tubular body, applying at least one tie-band to hold such flanges in depending position, telescoping the cap over the upper end of the tubular body with its flanges, which correspond in number and position to the panels of the body, overlapping such panels, and stabilizing the fiberboard assembly on the pallet by passing tension members at angularly-spaced positions around the tubular fiberboard container body to extend completely vertically around the cap and along the vertical panels of the body and tightening and securing them to the pallet to clamp those members axially together with the spacer contacting the upper end of the bag and the top wall of the cap and with a flat stabilizing frame applied to the top surface of the disc-like topwall of the cap with arms extending in angularly-spaced positions to the depending flanges at the polygonal edge of the cap, with said tension members extending over the arms of said frame, downwardly along the vertical panels of the body and beneath the pallet, said stabilizing frame being of substantially H-form and comprising arm members extending at right angles relatively so that the tension members will pass around the assembly at right angles to resist forces on the assembly exerted from various angular positions.
