| 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.

What is claimed is:
1. A flexible diluent container including an access port having first means for engaging the outlet portion of a second container which is closed by a removable stopper formed of resiliently compressible material and having an end wall of substantial thickness with a throat opening therethrough and an internal recess therewithin defining an inwardly facing shoulder inward of said end wall, said flexible container including extractor means comprising a protuberant engagement portion extending along a first axis for engaging such a stopper within said recess thereof for removal of the stopper from such a second container when engaged with said first means, wherein said engagement portion comprises a plurality of narrow vanes each joined with said protuberant engagement portion along said first axis and extending generally radially outward relative to said first axis such that their radially distal edges collectively define a transverse dimension of said engagement portion greater than the corresponding transverse dimension of said opening and said vanes are spaced from one another at said distal edges substantially greater distances than the thickness of said edges for ease of forcible passage through said throat and into said recess, said vanes having lateral axially proximal edges for thereafter engaging the internal shoulder of the stopper for effecting removal of said stopper from such a second container by said extractor means after entry into the recess of such a stopper.
