ABSTRACT:
A flexible diluent container has a vaned port plug which enhances or modifies the mechanical interlock with a stopper of an additive vial in a drug delivery system. The additive vial is screwed into the port of the diluent container with the recess of the vial stopper fitting over the engagement portion of the port plug. In doing so, the vanes or wings of the port plug present a minimal frontal area and hence minimal resistance to passage through the neck of the stopper recess. Also, being flexible, they tend to fold or wrap in against the core of the extractor as the vial and stopper are rotated and advanced into the seated position, thereby further reducing the axial forces involved. Once the port plug is fully seated, the vanes or wings open up to form a lateral shoulder on the inward side of the throat shoulder of the stopper, thus providing good gripping on the port plug when the user wants to manipulate the bag and pull the port plug-stopper combination off for the mixing of the contents of the two compartments through the port.
