ABSTRACT:
A dispenser for the application of a fluid or fluid-like material to another surface, such as, the surface of the skin is made up of an outer casing with an adjustable end cap at one end and an applicator brush at the opposite end, and a bellows-shaped container is disposed in the casing so as to be compressed by inward threaded adjustment of the end cap to discharge the material onto the applicator brush. A duckbill valve at the discharge end of the container automatically opens when a compressive force is applied to the contents within the container and, when force is no longer applied, will return to a closed position sealing off the end of the container.
