A container for holding fluent material comprises a bag of flexible material defining a volume for containing a load of material, a rigid base for supporting the bag, and tension members within the bag for constraining the bag to assume a shape in which the bag is generally rectangular in horizontal cross section when a load is contained within the volume. The bag has four side walls, a top opening in communication with the volume for loading of fluent material into the container, and a bottom. The tension members include a first elongate flexible tension member extending across the interior of the bag between a first side wall and a second side wall of the bag, and a second elongate flexible tension member extending across the interior of the bag between a third side wall and a fourth side wall of the bag. The respective ends of respective tension members are connected to respective side walls of the bag for constraining outward bulging of the side walls when a load is contained within the volume so that the bag assumes a generally rectangular horizontal cross section. The elongate tensions members of the set are so positioned and so dimensioned in transverse cross section that they do not significantly inhibit free flow of the fluent material within the volume in any direction.

Container for holding fluent material

A container for holding fluent material comprises a bag of flexible sheet material defining a volume for containing a load of the material. The bag has a side wall with an inside face and an outside face, and a bottom margin defining an open lower end of the bag. The container further comprises a substantially rigid, non-circular base for supporting the bag. Channels are formed in the base and extend at least partially around the base. The bag is fitted on the base with the bottom margin of the bag extending down on the outside of the base and with a portion of the bottom margin received in the channels of the base. Locking strips are positioned in the channels to overlie the portion of the bottom margin of the bag received therein. The container further comprises a clamping mechanism securable to the base for applying pressure to the locking strips to press the portion of the bottom margin of the bag against one or more surfaces of the channels thereby to sealingly secure the bag to the base.
