摘要
A vial structure wherein the neck of a two-compartment vial has a resilient stopper sealingly seated therein. The stopper has an upper projecting portion of smaller diameter, with the upper and lower portions being joined by an intermediate portion which defines a surrounding annular groove. A cap member surrounds the projecting portion of the stopper and is attached to the vial rim. The cap includes concentric inner and outer sleevelike skirts joined together by a top wall. The inner skirt snugly surrounds the upper stopper portion and terminates in a lower locking flange which projects into the annular groove to prevent the cap from being axially removed from the stopper. This inner skirt can be axially slidably inserted into the neck. The outer skirt is axially longer than the inner skirt and, at the lower end thereof, has a locking flange which resiliently snaps beneath the vial rim to lock the cap thereto. The outer skirt also has a second locking flange at a location spaced upwardly from the lower end so that, upon activation, the cap is pushed downwardly until the second locking flange snaps into position below the rim.
