Holder for Securing Toothbrush Heads

Abstract

A holder ( 1 ) for securing detachable toothbrush heads for electric toothbrushes, said toothbrush head having a movable disc or disc part supported by a shaft, and which is provided with bristles protruding substantially parallel to a first axis, said first axis extending substantially perpendicularly to the plane of the disc or disc part. The holder ( 1 ) is provided with a plurality of recesses ( 7 ), each of said recesses being adapted to accommodate in use at least the end of the toothbrush head supporting the disc or the disc part with bristles. Each recess has first supporting surfaces ( 8 ) to support in use the rim of the disc or disc part in the radial direction perpendicularly to said first axis, and second supporting surfaces ( 9 ) for supporting in use the rear side of the disc or the disc part in the axial direction parallel to said first axis.
