ABSTRACT:
An additive vial for transferring a liquid medicament into an evacuated container is disclosed comprising a liquid medicament storage container having a neck terminating at a generally flat-rimmed bead defining a mouth opening in the container. Closing the mouth of the container is a rigid disc, having a hollow, generally cylindrical piercing member extending outwardly from a central location of the disc terminating in a needle point. An elastic sealing means is provided around and contiguous an outer portion of the container rim. The sealing means also overlies an outer peripheral portion of the exterior surface of the disc with respect to the exterior of the container. A penetrable tip is provided over the needle point of the piercing member, and a removable, outwardly projecting cylindrical portion of a closure extends over and around the tip covering the needle point. The closure also includes an annular rim at least partially overlying an outer peripheral portion of the disc and the sealing means, and a depending skirt extending downwardly from the annular rim having the lower portion turned inwardly under and against the container bead to constrict the sealing means and the disc toward the rim effectuating a seal about the rim of the container.
