ABSTRACT:
Container apparatus (2) for transporting and storing fluid material, comprising a flexible bag (8), a rigid frame member (10) which is attached to an upper portion of the flexible bag (8), a rigid base (12), and elongate support members (16) which are positioned outside the flexible bag (8) and which are movable from a first position in which they extend between the rigid frame member (10) and the rigid base (12), to a second position in which they allow the sides of the flexible bag (8) to collapse, and the container apparatus being characterized in that the rigid frame member (10) is provided with inboard portions (13) which are attached to the sides (9) of the flexible bag (8) thereby to draw the sides of the flexible bag substantially inboard of the rigid base and force the fluid material towards corners of the flexible bag which are formed by points of attachment of the flexible bag to corners of the rigid frame member and to create an upper portion to the flexible bag which has opposing sides which are inclined toward each other in order progressively to reduce the volume for a liner bag (6) to occupy as it is filled, and characterized in that the container apparatus is free of constraint members which extend parallel to the rigid base to constrain the sides of the flexible bag.
