Abstract

Abstract The present invention relates to an Improved Mascara Applicator which is used to apply mascara to eyelashes. The Improved Mascara Applicator of the present invention incorporates a unique applicator design which contains a multiplicity of rows of closely spaced and evenly spaced applicator flukes which permits each eyelash to be evenly coated with mascara. The unique applicator design also incorporates a series of communicating channels between the multiplicity of rows of applicator flukes in order to permit mascara to flow from one row to the next. This built in mascara reservoir channel design feeds each of the mascara coating flukes with mascara in order to assure proper mascara flow to each eyelash. This unique design further eliminates the requirement of frequently dipping the mascara applicator into a pool of mascara to replenish the applicator. The present invention also relates to an improved method of manufacturing the head of this mascara applicator.
