Abstract
A molded plastic applicator for cosmetics including a plastic panel lying substantially in a mold plane when formed and bent out of the mold plane to surround an extended longitudinal axis when the applicator is assembled. A plurality of openings or projections are formed in or on the panel so as to be oriented substantially in a common pull direction transverse to the mold plane when the panel lies in the mold plane and oriented substantially radially of the longitudinal axis when the panel is bent to surround the axis. A retainer holds the panel, when bent, in surrounding relation to the axis. The panel may be formed as a plurality of free-ended limbs, radiating from a hub through which the longitudinal axis extends, and bent down around the axis.
