  • Patent number: 4580587
    Abstract: A filled toothbrush or filled shaving brush which includes a tubular handle 4, in the hollow of which toothpaste or shaving snap is placed. At one end of the handle is a removable bristle holder, supplied with bristles, snap mounted so that it can be turned relative to the handle. The bristle holder has a connecting channel which leads from the bristles into the hollow of the handle and up to its end. A metering piston is mounted on the connecting channel and can be moved axially by rotating the handle relative to the bristle holder, and is at the same time prevented from rotating, relative to the connecting channel. Both the outer circumference of the piston and the inner surface of the handle are threaded to effect axial movement of the piston. The axis of bristle holder 1 may be offset from the rotational axis of handle 4 so that unintentional turning of the bristle holder relative to the handle, when in use, is prevented.
