Abstract
A liquid dispensing nozzle assembly is provided for mounting on a liquid container and dispenser having a flexible wall and liquid storage cavity for manually squeezed dispensing of liquid from the cavity through the nozzle assembly. The nozzle assembly maintains the liquid, such as contact lens cleaning and conditioning solutions in sterile condition during storage and repeated dispensing of the liquid from the container cavity. The nozzle assembly includes a liquid conduit for communication form the container cavity to a liquid discharge port from the nozzle assembly to enable dispensing of the liquid displaced by manually squeezing the flexible wall of the container. The nozzle assembly also includes a sealing element for sealing the liquid conduit against liquid leakage in which the sealing element has a composition comprising polytetrafluoroethylene which can provide sealing engagement directly against a molded plastic surface of either a molded component of the nozzle assembly or the container-dispenser. The sealing element can be provided by a peripheral portion of a polytetrafluoroethylene flow control diaphragm to provide an integral, sealing ring thereon.
