Abstract
A cosmetic product package, particularly a mascara package, including a dual wiper mechanism which virtually eliminates the messiness problems of typical mascara applicators. The dual wiper mechanism has a resilient inner wiper and a resilient outer wiper spaced apart from one another within a supporting structure forming a residual mascara chamber therebetween. The inner wiper has a relatively small opening which provides most of the doctoring of the bristles. The outer wiper has a larger opening which primarily doctors the stem. Mascara which collects in the residual chamber flows through conduits around the inner wiper back into the primary reservoir, or alternatively to a discard reservoir. A mechanism to doctor more mascara from the brush upon insertion than upon removal of the brush may also be provided.
