Abstract:
A modular MicroBarrier cap delivery system for integration in the neck of a container for contamination-free delivery of a flowable material residing in the container comprising:a cap including a seat operatively connected with the reservoir for defining a flow path for the flowable material; said seat comprising one or more vanes, each vane having a major surface aligned for imparting unidirectional laminar flow in the flow path, and a blocking portion for preventing flow when an adjacent seal is conformably mated with the seat in a first or closed state;said seal responsive to an applied pressure comprising a sealing surface for conformably mating with the seat to prevent flow in said first state, said sealing surface defining a bore coaxially aligned with the blocking portion of the seat for enabling unidirectional flow through the bore when the seal and seat are in a second or open state;means for activating and deactivating the pressure to enable said seal to transition reversibly between the first and second states;means for attaching the modular cap to the neck of a container;a closure that movably attaches to the modular cap for sealing the bore of the said seal when not in use.
