Abstract
This brush, in particular for the application of mascara to the eyelashes, is constituted by a central elongate core which is surrounded at least partly by bristles radially implanted along longitudinal rows, one row of longer bristles whose ends constitute a ridge alternating with one row of shorter bristles. According to the invention, the ends of the bristles situated between two adjacent ridges are contained in a surface-envelope with a non-convex profile (flat or with a concave profile). During making up, the lashes are separated by the bristles of each ridge and they are charged with the make-up product coming from the regions situated between the ridges which can constitute, by an appropriate choice of the number of ridges (four in particular), a large application surface. The manufacture of such a brush is extremely simple since it suffices to effect a peripheral milling of a brush of the conventional type.
