ABSTRACT:
A unitary, hermetically-sealed but pierceable dispensing container, suitable for packaging parenteral solutions, is made from a flexible, generally tubular body of thermoplastic material utilizing a form, fill and seal technique and a movable, composite mandrel that includes a forming ram member for compression molding from within the container a container wall portion which includes a pierceable membrane. The tubular body is closed at one end and terminates at the other end in a draining region having an access aperture or port sealed by a unitary membrane of predetermined thickness. The membrane permits penetration of a cannula therethrough without coring, and an annular sealing means surrounding the aperture is adapted for frictional and sealing engagement of the cannula after the membrane has been penetrated.
