Abstract
A cleaning brush, particularly toothbrush, has a handle and an elongated brush head, which comprises a flexible bristle carrier tapering in longitudinal cross-section from the handle to the front end of the brush head and bristles fixed thereto. The bristle carrier is formed from two longitudinally, successively arranged portions interconnected in transitionless manner and made from materials having differing characteristics and at least the front portion is made from an elastomer. The materials, cross-sections and bending length of the portions are so chosen that the front portion is deflectable with a smaller radius of curvature than the other portion.
