<p>A closure structure for a two-compartment vial having a stopper sealingly seated within the neck opening of the vial, and a cap interconnected between the stopper and the vial neck. The stopper has a cylindrical portion which protrudes outwardly of the vial neck and is surrounded by a resilient sleevelike collet associated with the cap. The collet is mechanically axially interlocked to the stopper and, together with the cylindrical stopper portion, moves into the neck opening when the closure is urged toward the vial to activate the latter. A cammed or tapered relationship exists between the collet and the vial neck which increases the gripping of the stopper by the collet when they are moved into the neck opening.</p> |
