A stackable container for holding large quantities of fluent material comprises an outer load-bearing multi-layer corrugated paperboard wall and an inner liquid-impervious bag. A plate with an opening through it is supported on a peripheral ledge slightly below the top of the container wall. The ledge is provided by the upper edge of one or more inner layers of the container wall. The mouth of the bag extends upwardly through the opening in the plate and is secured by a strap to a bag holder on the plate. A load transmitting member on the upper surface of the plate is of substantially the same thickness as the ledge, and extends to the same height as the outer layer of the wall. The bag holder is a ring, larger than portions of the opening in the plate and may be passed transversely through the opening but not when parallel to the plate.
