ABSTRACT:
A flexible diluent container has a helical threaded 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 helical threads of the port plug engage the stopper throat in a complementary manner to enhance the axial mating engagement therebetween and hence minimize or avoid axial resistance to passage of the large plug head through the neck of the stopper recess. With the helical threads of the port head having a lead greater than the threads of the vial which engage the port, a positive axial drawing action may be obtained so as to induce or "pull" the engagement portion of the port plug into the recess of the stopper. A shoulder at the base of the plug head engages 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.
