Patent ID: 6968946

Claim:
A container including a pallet having a rigid, planar platform portion defining a central discharge port and a planar annular surface in surrounding relation to the discharge port, a tubular sleeve supported at a lower edge thereof on the pallet, and a flexible liner positioned within the sleeve, characterized in that: the pallet includes a door selectively closing the central discharge port; 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; and the effective combined height of the upper and lower portions of the liner within the sleeve with the upper edge of the upper liner portions 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 proximate the discharge port whereby, with the door closed, 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, the annular platform surface, and the lower portion of the liner with the liner fully extended.
