Abstract
An apparatus for applying liquid agent to a substrate includes a cup member for preventing liquid agent from scattering. Cleaning agent is supplied to an inner circumferential surface of the cup member through openings located at an upper portion of the inner circumferential surface. The structure for supplying the cleaning agent is integrally formed on an outer circumferential surface of the cup member. The apparatus also has a slanted surface for regulating and guiding air, liquid agent and cleaning agent downwardly through the cup member. Cleaning agent is supplied to the slanted surface through openings which are located at an upper portion thereof. Preferably, the openings are angled so that cleaning agent is directed substantially horizontally therefrom. Preferably, the apparatus has fine irregularities for spreading cleaning agent on the inner circumferential and slanted surfaces.
