Additive transfer unit with piercing member having a penetratable protective tip
First Claim
1. An additive vial for transferring a liquid medicament into a container comprising:
- a liquid storage container for holding the medicament to be transferred, said container having a neck portion terminating at a bead, said bead having a rim, with the inside dimension of the rim defining the circumference of a mouth of the container;
a disc of rigid material closing the mouth of the container, with a peripheral portion of said disc overlying at least a portion of the rim of the container;
a rigid piercing member extending from a central location of the disc in a direction axially outwardly of the mouth of the container, terminating in a needle point;
an aperture extending from the needle point through a longitudinal axis of the piercing member and continuing through the disc along such axis to define a passageway from the interior of the container to the exterior of the container;
elastic sealing means around and contiguous the outside diameter of the disc overlying at least a portion of the rim of the container, and overlying an outer peripheral portion of the disc;
a protective tip providing a seal over the needle point of the piercing member, said tip being penetrable by the needle point;
a aluminum closure having a removable, outwardly projecting portion extending over and around the piercing member and the protective tip, an annular rim at least partially overlying an outer peripheral portion of the sealing means, and a depending skirt extending downwardly from the annular rim; and
wherein a circular portion of the annular rim overlying the outer portion of the disc is indented into the sealing means toward the disc around the circumference of the rim, constricting the elastic sealing means and the disc toward the rim of the container to maintain a seal about the rim of the container.

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.

26. An additive vial for transferring a liquid medicament into an evacuated container comprising:
-
a liquid storage container for holding a medicament to be transferred, said container having a neck portion terminating at a bead having a generally planar rim, with the inside dimension of the rim defining the circumference of a mouth of the container; a plastic disc concentrically placed over and closing the mouth of the container, with a peripheral portion of said disc overlying at least an inner circumferential portion of the rim of the container; a generally cylindrical, plastic piercing member of one piece with and extending from a central location of the disc in a direction axially outwardly of the mouth of the container, terminating in a pyramid-shaped needle point; an aperture extending from a plurality of slots located near the tip of the needle point through a longitudinal axis of the piercing member and continuing through the disc along such axis to define a passageway from the interior of the container to the exterior of the container; an elastic sealing member around and contiguous the outside diameter of the disc overlying at least a portion of the rim of the container, and overlying an outer peripheral portion of the disc; a protective elastic tip providing a seal over the needle point of the piercing member, having a generally planar top surface, said tip readily penetrable by the needle point; an aluminum closure having a manually removable, outwardly projecting cylindrical portion extending over and around the piercing member and the protective tip, an annular rim at least partially overlying an outer peripheral portion of the disc and the sealing member wherein a circular portion of said annular rim is indented into the underlying sealing member, thereby constricting the sealimg member and the disc toward the rim of the container to maintain an air-tight seal thereabout, and a depending skirt extending downwardly from the rim around the outside portion of the elastic sealing member and the container bead.
