Abstract
An applicator unit for a liquid or semi-liquid product that wipes excess product from the stem and applicator. The excess product is wiped by a sleeve through which the applicator charged with the product is caused to pass. The sleeve is open at its two ends, and having an internal surface capable of retaining a reserve of the product by the surface tension effect. The force of the surface tension exerted between the sleeve and the product contained therein is greater than the force of the surface tension exerted between the free end of the applicator and the product. Thus, excess product remains in the sleeve and not on the applicator.
