ABSTRACT:
An apparatus is used to apply medicament to an eye and stores the medicament in a medicament chamber. A nozzle is coupled in fluid communication with the medicament chamber and is formed by an outer nozzle portion and an inner nozzle portion received within the outer nozzle portion. A seam is formed by the interface of the inner nozzle portion and the outer nozzle portion and is normally in a closed position to prevent the passage of medicament through the nozzle. The seam opens in response to the flow of medicament of sufficient pressure into the seam to permit the passage of medicament through the nozzle for release into the eye.
