ABSTRACT:
A container including a rigid plastic pallet having a platform portion defining a central discharge port, a tubular cardboard sleeve supported at a lower edge thereof on the pallet, and a flexible plastic liner positioned within the sleeve. The liner includes an upper portion of uniform cross-sectional configuration conforming to the cross-sectional configuration of the sleeve and a lower portion of downwardly and inwardly tapering configuration terminating in a bottom liner opening positioned proximate the pallet discharge port. The effective combined height of the upper and lower portions of the liner, with the upper edge of the upper liner portion secured to the upper edge of the sleeve, is greater than the distance from the upper edge of the sleeve to the upper face of the pallet so that the sides of the lower portion may bulge outwardly in response to the loading of contents into the liner to at least partially fill the annular void defined between the sleeve and the lower portion of the liner with the liner fully extended. The pallet port is selectively closed by a trap door pivotedly mounted on the pallet. The pallet port is selectively closed by a trap door pivotally mounted on the pallet and the liner includes a discharge spout extending downwardly from the lower portion of the liner for passage through the pallet discharge port.
