Abstract
A toothbrush comprises a handle, a head constructed as an at least one-sided open casing, a brush part insertable in its open side and having a support and a bristle facing, as well as locking means in the form of interengaging projections and recesses within the casing and on the support for fixing the brush part, the casing having a cheek supporting the support over its entire circumferential surface and on the head are provided means for the toolless pressing out of the brush part. In order to separate the functions 'sealing' and 'locking', on its inside the casing cheek and on its periphery the support are constructed as completely smooth-walled sealing surfaces and, outside the sealing surfaces, the locking means have inwardly displaced, resilient detents.
