Abstract
A cosmetic brush having a flare-shaped ferrule at its mouth, through which an advanceable and retractable, resilient bristle brush extends. The brush connects in the handle, with an elevator mechanism that has a cupped upper end which carries the brush, and effects the axial movement thereof. As more bristles are exposed at the ferrule's flare-shaped mouth in response to their advancing movement, the degree of flare of the brush increases. The resilience of the exposed bristles along with the flare adjustability, creates the same effect as a plurality of different sized, smaller brushes. There is thus eliminated the need for carrying multiple different sized brushes that might otherwise be required in order to produce an equivalent optimal brushing result.
