ABSTRACT:
This invention relates to retractable brushes, of the general type having bristles which can be retracted into the casing of the brush, or moved outwardly from the casing into the position at which the bristles are used. Wiping flaps are provided on a retractable brush to engage and wipe the bristles as they are extended and retracted through the openings in the front wall of the brush. The wiping flaps may take the form of a thin membrane extending across each of the openings and formed with slits. The brush may be arranged to be extended and retracted by producing relative rotation between the front and rear members of the brush. To assist in securing the front and rear members together, a detent connection may be provided between one of the members and an axial post connected to the other member. Detent elements may also be provided between the front member and cam members which are provided on the rear member. A retractable brush is produced having soft comfortable bristles for personal grooming, yet with a relatively rigid casing, both made of the same plastic material.
