  • Additive transfer unit having a slidable piercing member
    Patent number: 3987791
    Abstract: 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.
