Abstract
A flexible collapsible container is filled with fluid by connecting a fluid conduit to a tubular port which communicates through one of the walls of the container to the container interior, and rupturing a sealing diaphragm that closes the bore of the tubular port. One then passes fluid through the conduit to fill the container. Thereafter, one seals either or both the tubular port and plastic wall which carries it to the other, opposed plastic wall of the container with seal line means to close off flow communication between the bore of the tubular port and a major portion of the container interior which contains the fluid. The effect of this is to block flow communication between the bore and the fluid so that the contents of the container remain sealed on disengagement of the fluid conduit from the tubular port.
