An applicator device, particularly suited for mascara, may deliver high or low viscosity liquids or semi-liquids, and contains a valve controlling flow between a product reservoir, an intermediate pooling area, and a product dispensing chamber. The arrangement prevents backflow to the product reservoir, precluding contamination of the product supply. Product delivery from the product dispensing chamber is from one of several methods. In one method, a plurality of prongs each comprise a conduit to the product dispensing chamber and thereby allow for dispersed product delivery from the prong tips. Alternatively, there may be one or more openings on the applicator head being interconnected to the dispensing chamber, which permits product to extrude between the rows of prongs and thereby be applied to a receiving surface. A third embodiment combines the two methods along with alternating height prongs to more effectively apply mascara onto all sides of a user's lashes.
