Abstract:
A method for increasing the capacity of a flexible container for storage and administration, the method comprising the steps of:providing a pair of flexible planar sheets; joining the flexible planar sheets together to thereby provide a flexible container having a flexible planar front sheet opposing a flexible planar rear sheet along a common plane, the front sheet being sealably attached to the flexible rear sheet along a common peripheral edge to form a volume enclosure; expanding the volume enclosure by introducing a pressurized fluid into the volume enclosure to permanently stretch at least one of the front or rear sheets to thereby increase the capacity of the volume enclosure; and wherein the step of expanding comprises the steps of: maintaining the rear sheet and the common peripheral edge substantially against the common plane; and inflating the volume enclosure with a pressurized gas to permanently stretch a portion of the front sheet outwardly from the common plane.
