Unitary, hermetically-sealed but pierceable dispensing container
First Claim
1. A unitary, hermetically-sealed but pierceable dispensing container, suitable for containing parenteral solutions, which comprisesa flexible, generally tubular body of thermoplastic material, closed at one end and terminating at the other end in a draining region provided with an annular sealing means unitary with said tubular body and defining an access aperture, and a pierceable membrane hermetically occluding the aperture and being unitary with said sealing means;
- said membrane being sufficiently thin to permit penetration by a cannula without coring, and said annular sealing means being adapted to receive the cannula in a sealing, frictional engagement when the membrane has been penetrated.

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.
