ABSTRACT:
A valved medication container for facilitating needleless transfer of medication from the container to a patient. Four embodiments of valve members are disclosed. The first embodiment employs a slidable actuator which is engaged by the nose portion of a syringe and deflected into the container through a slit elastomeric membrane. A second embodiment employs a duckbill which the nose of the syringe biases to an open position. The third embodiment uses axially opposed flapper valves which the nose of the syringe pushes open. The fourth embodiment employs a slidable actuator with a T-shaped passageway which is moved to the open position by the syringe. A vent having a one-way valve for influx of air is provided for larger containers.
