An additive container and transfer unit for transferring a solution from the additive container to a container which is under a vacuum, the transfer unit including a closure having a transfer pin or piercing member which is axially movable from a first position to a second position within a supporting member or guide. The additive container and transfer unit is particularly applicable to the transfer of a medicament within the container to a vacuumized parenteral fluid container. In this application, the additive container is inverted and the point of the transfer pin projecting from the closure is positioned on the I.V. fluid bottle stopper. As downward thrust is applied to the additive container, the end of the transfer pin projecting from the closure will pierce the I.V. fluid bottle stopper. As further thrust is applied, the additive container closure will move along the transfer pin, the other end of the transfer pin thereby piercing the diaphragm portion of the stopper within the transfer unit thereby providing a pathway between the two containers through the passageway in the transfer pin. The vacuum within the vacuumized container will then draw the solution within the additive container into the vacuumized container.

An additive transfer unit for storing and transferring of a medicament to a container having an exposed closure and a vacuum therein; said transfer unit comprising a container for storing the medicament to be transferred, said container having a rigid neck portion defining a finish, the opening in said container being sealed by a closure affixed thereto; said closure having a shoulder for resting against said finish of the rigid container neck, said closure including a puncturable stopper with a pierceable diaphragm portion positioned in sealing engagement with the opening in the container and in a substantially stationary manner; a tubular member having a cylindrical portion, the cylindrical portion including a central opening therein for slidably receiving a piercing member; said tubular member including an undercut in the outside surface of the cylindrical portion thereof, sealing means positioned in said undercut; a hood engageable with the cylindrical portion of the tubular member and the sealing means to cover the piercing member and tubular member prior to use of the unit; said tubular member being positioned and arranged so that the opening therein overlies the diaphragm portion of said stopper; crimping means to affix the closure and tubular member to the container; said piercing member being positioned within said central opening in said member and having a passageway therethrough for the flow of said medicament and a point on both ends thereof; said piercing member having an integral stop and being movable from the first position for entry through the closure of the vacuumized container with said integral stop constructed and arranged to contact said exposed closure of vacuumized container to a second position for puncturing of the stopper in the additive container to thereby provide a pathway between the containers and permit the medicament within the additive container to transfer into the vacuumized container.
