Abstract
Abstract An improvement in a bin-type, bulk fluid container. The container comprises a rigid carton containing a plastic bag. The bag has an evacuation element in its bottom. The bag rests on an insert in the carton. The insert comprises a body molded in one piece from relatively dense, expanded plastic. The insert includes an upper panel supported by walls and partitions between the walls. The upper panel has an aperture through it for the evacuation element and forms a generally funnel-shaped surface inclined downwardly to the aperture.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
152 words
In a bin-type, bulk fluid container where the container includes a carton having a bottom wall, side walls and a top wall, with an orifice formed in the bottom wall between said side walls and a bag for holding fluid disposed within said carton and having a drainage element adapted to fit through the orifice, the improvement comprising: a) a removable insert mounted in said carton underneath said bag; b) an aperture through said insert in registry with said orifice; c) said insert having a support surface on which said bag rests; d) a plurality of inclined partition panels disposed beneath said support surface, said support surface having two side panels and a plurality of inclined partition panels extending parallel to the side panels; e) said support surface having a shape effective to deform said bag so as to cause liquid in said bag to flow by gravity toward said drainage element.
