ABSTRACT:
A closure for a vial or the like includes a cap clampingly engaging the rim of the vial with a resilient stopper therebetween. During the assembly of the closure, an initially one-piece cap device having an uppermost outer sleeve affixed to an integral cap provided with an outwardly flared skirt, is pressed downwardly toward the stopper disposed atop the vial rim. Continued pressure fractures the sleeve from the cap and urges the sleeve downwardly to bias the resilient skirt inwardly, causing lips thereon into a captive position beneath the vial rim. Continued downward movement of the sleeve results in a locking ring on the interior of the sleeve becoming snap-fitted within a recess in the cap skirt. An aseptic condition of the vial contents is maintained as the stopper remains under vertical compression by the top wall of the cap and in view of an annular ring on the cap top wall which is urged into a circular slot provided in the rim of the stopper, overlying the vial rim. Access to the vial contents through the stopper septum is accomplished by breaking away a frangibly attached top post on the cap.
