Method and apparatus for fixing a connector assembly onto a vial with a crimp cap

摘要

A method and apparatus for attaching a connector assembly onto a vial is disclosed. The connector assembly features a protective cap, a collar attachable to the rim of the vial, and a crimp cap for securing the collar to the rim. A vial access device is contained within the collar. One or more ribs are provided adjacent a distal portion of the collar to seal against the stopper obturating the vial. The collar is provided with one or more slits which render the collar flexible in directions radial and axial to the central axis of the vial to compensate for variations in tolerances or dimensions present in the various components. The crimp cap can be supplied preattached to the collar in an uncrimped condition.
