Abstract: A reservoir for a cosmetic viscous or liquid product. The reservoir includes a body and a wiper, the reservoir being designed so that a cosmetic applicator, which includes a core and bristles mounted on the core, can be moved from the inside of the reservoir to the outside of the reservoir through the wiper. The wiper includes a tubular sleeve and a multiplicity of ribs disposed on the tubular sleeve. The ribs longitudinally extend along a longitudinal direction parallel to a longitudinal direction of the sleeve, and are tapered in a radial direction from the inner wall of the sleeve toward the inside of the sleeve. Moreover, the ribs are arranged on an inner wall of the sleeve and guide the bristles of the cosmetic applicator during its passage through the wiper.
