Abstract
The invention disclosed is a sealed fluent material container having a chamber with an opening provided with a manually operable primary closure mechanism and a secondary closure mechanism that may be operated either manually or automatically. Manual removal of the primary closure mechanism from the chamber opening allows the secondary closure mechanism to extend a laterally moveable tongue from a horizontal guide recess on the top of the container to a normally closed position covering the opening. An engagable tab on the secondary closure permits the retraction of the moveable tongue against the biasing means to expose the chamber opening. The container has particular utility for use in automated chemical dispensers, analyzers and related equipment for the analysis and testing of blood, physiological fluids and other biological samples.
