Abstract

Abstract A stopper for a medicament vial including a thin central zone thereof and a beveled sleeve is supported over the outer surface of the thin central zone of the stopper by means of three radially outwardly extending and arched legs anchored to the peripheral portions of the stopper at their outer ends. The sleeve is tapered toward the central area of the stopper and the end of the sleeve adjacent the stopper is beveled for piercing the thin central zone of the stopper. However, the legs support the sleeve with its beveled end at least closely adjacent the stopper and the arched legs are bendable whereby a thrust on the outer end of the sleeve will be sufficient to bend the legs and advance the beveled end of the sleeve toward the central area of the stopper for piercing the same. The sleeve includes an outer barb for retention through the thin central area of the stopper and a conventional aluminum seal is secured over the stopper and the adjacent end of the vial and also covers the stopper piercing sleeve and its bowed support legs.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 190 words
In combination with a vial having a stopper therein for closing the vial, said stopper including spaced outer peripheral portions and a thin central portion a stopper piercing and needle gripping attachment for said stopper, said attachment comprising an axially short sleeve constructed of shape retentive and yet resilient material, positioned on the outer side of the central portion of said stopper with one end of the sleeve in end opposing relation relative to said central area of said stopper, and support means supporting said sleeve from said stopper for advancement toward and movement of said one end of said sleeve through said central area, said one end of said sleeve being beveled and sharpened, said sleeve tapering, both internally and externally, toward said one end thereof, whereby said tapered sleeve receives a syringe needle in the large diameter end of said sleeve, after the sleeve has been inwardly displaced to pierce said central area, and said needle is tightly gripped by said sleeve for total support of the sleeve and said vial from the needle when the vial is disposed in an inverted position with the needle positioned therebelow.
Claim 2
Dependent Claim 190 words
In combination with a vial having a stopper therein for closing the vial, said stopper including spaced outer peripheral portions and a thin central portion a stopper piercing and needle gripping attachment for said stopper, said attachment comprising an axially short sleeve constructed of shape retentive and yet resilient material, positioned on the outer side of the central portion of said stopper with one end of the sleeve in end opposing relation relative to said central area of said stopper, and support means supporting said sleeve from said stopper for advancement toward and movement of said one end of said sleeve through said central area, said one end of said sleeve being beveled and sharpened, said sleeve tapering, both internally and externally, toward said one end thereof, whereby said tapered sleeve receives a syringe needle in the large diameter end of said sleeve, after the sleeve has been inwardly displaced to pierce said central area, and said needle is tightly gripped by said sleeve for total support of the sleeve and said vial from the needle when the vial is disposed in an inverted position with the needle positioned therebelow.
Claim 3
Dependent Claim 32 words
