Abstract
The present invention is a capped-closure mounted on a container for storing reagents for use in an automated analytical instrument having an actuating device mounted thereon. The capped-closure comprises a base being generally cylindrical, wherein the base has one end opening to the container and the other end having an opening through which the reagents can be aspirated. The capped-closure further comprises a lever assembly pivotally mounted on the base. The lever assembly has one end which forms a cap operable to seal the opening the base sufficiently tightly to prevent evaporation from the container. The other end of the lever assembly forms a tab operable to pivot the lever assembly to a substantially perpendicular position with opening of the base when depressed for exposing the opening of the base to a device for aspirating the reagent from the container. The capped-closure finally comprises spring mechanism connected between the base and the lever assembly for urging the lever assembly to the substantially perpendicular position.
