Abstract
A container and dispensing device for mascara and the like, has a small bottle with an externally threaded neck of reduced diameter, into which a molded plastic one-piece separator member is pressed. The device has an applicator screw cap which screws onto the bottle neck, and which has an applicator rod depending from an intermediate transverse sealing wall. The applicator rod projects from the bottom of the screw cap, being surrounded by the walls of the separator member, and carries a brush for disposition in the bottle. Above the bottom end of the separator member is a doctor blade, which normally surrounds the juncture of the brush and applicator rod. The doctor blade has an annular sealing bead which seals against the bottom surface of the applicator rod, and the latter is commensurate in diameter with that of the brush. The separator member also seals against the sealing wall of the screw cap, whereby the separator member is sealed and maintains the applicator rod in a clean condition. The orifice of the doctor blade can have numerous different configurations to effect different wiping effects on the brush as the latter is withdrawn for use.
