The system includes an elastomeric stopper, a retainer member, a locking member, a cap assembly and a piercing member. The retainer member is arranged to snap onto the vial and the locking member slid with respect to the retainer member to permanently seal the vial. The cap assembly includes a cap and a band and is coupled to the locking member. The cap releasably holds the piercing member. The band is arranged to be removed to enable the cap to move the piercing member to penetrate the stopper, whereupon the cap can be removed. The piercing member is arranged to be connected to a syringe or other instrument to withdraw the vial's contents. ## Claims ### Claim 1 A cap system for a pharmaceutical vial having an interior in which a flowable material is disposed, an opening to the interior of the vial and a flanged neck surrounding the opening, the flanged neck having an undersurface, said cap system comprising: an elastomeric stopper configured to be secured to the vial; a retainer member including first portions configured to be secured to the vial with said first portions flexing over the flanged neck of the vial and then snapping into engagement with the undersurface of the flanged neck of the vial; a locking member comprising a peripheral sidewall including inwardly projecting members, said locking member being slidable to a position with respect to said retainer member whereupon said inwardly projecting members apply an inward force on said first portions of said retainer member to permanently seal said vial; a cap member movable with respect to said locking member from a retracted position to an extended position; and a piercing member coupled to said cap member and having a piercing tip configured to pierce through said elastomeric stopper into the interior of the vial when said cap member is moved to said extended position. ### Claim 2 (depends on 1) The cap system of claim 1, wherein said first portions comprise a plurality of resilient fingers. ### Claim 3 (depends on 1) The cap system of claim 1, wherein said cap member is slidably coupled to said locking member to enable said cap member to be slid from said retracted position to said extended position. ### Claim 4 (depends on 1) The cap system of claim 1, wherein said cap member comprises a socket and wherein said piercing member is releasably secured in said socket. ### Claim 5 (depends on 1) The cap system of claim 1, wherein said cap member comprises a portion of an assembly additionally comprising a band releasably secured to said cap member, said band being arranged to be removed from said assembly to enable said cap member to be slid from said retracted position to said extended position. ### Claim 6 (depends on 5) The cap system of claim 5, wherein said cap member and said band member are releasably secured to each other by a frangible connection. ### Claim 7 (depends on 6) The cap system of claim 6, wherein said band member comprises a pull tab to enable one to grasp said tab to break said frangible connection. ### Claim 8 (depends on 6) The cap system of claim 6, wherein said frangible connection extends about the periphery of said cap member. ### Claim 9 (depends on 1) The cap system of claim 1, wherein said cap member is configured to be removed from said piercing member after said cap member is in said extended position leaving said piercing member in place extending into the interior of said vial. ### Claim 10 (depends on 1) The cap system of claim 1, wherein said locking member comprises an inwardly projecting ledge from which at least one of tab projects, and wherein said piercing member comprises a flange having an upper surface and a lower surface, said lower surface of said flange being configured to be disposed on said ledge, said upper surface of said flange being configured to be trapped under said at least one tab to hold said piecing member in place when said cap member is in said extended position. ### Claim 11 (depends on 10) The cap system of claim 10, wherein said cap member includes a socket having an internally threaded portion and wherein said piercing member comprises an externally threaded portion screwed within said internally threaded portion of said socket, said cap member being arranged to be unscrewed from said piercing member after said cap member is in said extended position, whereupon said cap member can be removed from the vial leaving said piercing member in place extending into the interior of the vial. ### Claim 12 (depends on 11) The cap system of claim 11, wherein one of said ledge and said lower surface of said flange includes at least one recess the other of said ledge and said lower surface of said flange includes at least one tooth for receipt in said at least one recess to prevent rotation of said piercing member when said cap member is unscrewed therefrom. ### Claim 13 (depends on 11) The cap system of claim 11, wherein said cap member comprises a portion of an assembly additionally comprising a band releasably secured to said cap member, said band being arranged to be removed from said assembly to enable said cap member to be slid from said retracted position to said extended position. ### Claim 14 (depends on 11) The cap system of claim 11, wherein said cap member and said band member are releasably secured to each other by a frangible connection. ### Claim 15 (depends on 14) The cap system of claim 14, wherein said band member comprises a pull tab to enable one to grasp said tab to break said frangible connection. ### Claim 16 (depends on 15) The cap system of claim 15, wherein said frangible connection extends about the periphery of said cap member. ### Claim 17 (depends on 1) The cap system of claim 1, wherein said piercing tip is hollow and wherein said piercing member additionally comprises a connector for connecting said piercing member to a device for withdrawing at least a portion of the flowable material in the vial through said piercing member. ### Claim 18 (depends on 17) The cap system of claim 17, wherein said connector comprise a luer fitting.
