Abstract
Abstract A pharmaceutical vial and cap assembly of the kind comprising an open-top vial covered by a cap with a depending peripheral skirt, the inner surface of the cap skirt and the outer surface of the vial having complementary mating interlock elements that preclude manual removal of the cap, the cap including an integral tear member, defined by one or more weakened junction lines, such that pulling away the tear member allows ready manual removal of the cap; the cap top includes a fill hole that for filling the vial with the cap in place, and the fill hole is closed, after filling, by a resilient stopper having a configuration effectively precluding manual removal, so that post-filling tampering and contamination are precluded. The stopper is preferably molded together with the cap, being connected to the cap by an integral strap.
