ABSTRACT:
A nozzle assembly is provided for a container and dispenser which maintains a supply of liquid, such as saline solution for contact lenses, in sterile condition during storage and has a flexible wall for manually squeezed displacement of the dispensed liquid from a storage cavity within the container. The nozzle assembly includes first and second conduits for defining separate fluid flow paths between an opening from the container and a nozzle from the structure. The first conduit enables flow of the stored liquid to be discharged from the nozzle orifice during squeezing of the flexible wall. The second conduit includes a barrier obstructing flow of the liquid through the second conduit which obstruction is permeable to air and impermeable to bacteria, allowing aspiration of air through the second conduit into the liquid storage cavity to replace the dispensed liquid and re-expand the container wall while preventing entry of any bacteria with the aspirated air.
