Abstract

Flexible brush head (14) for a toothbrush (10), having a bristle carrier (16) which consists of a first, hard, elastic plastic and is subdivided by segments (17), which are arranged one behind the other in the longitudinal direction of the brush head (14), by tunnels (20) running transversely with respect to the longitudinal axis of the brush head (14). The segments (17) of the bristle carrier (16) and the tunnels (20) extend preferably over the entire width of the brush head (14). The tunnels (20) are filled with a second, soft, elastic plastic and connected to one another via a groove (30) provided laterally on the bristle carrier (16). The regions (22, 22') of the bristle carrier (16), which bound the tunnels (20) on the bristle-carrying side of the brush head (14) and on the side located opposite the bristle-carrying side, are elastically deformable and, in the event of the bristle-carrier segments (17) being deflected during use, act as a bending-limiting structure.
