The invention disclosed relates to a toothbrush which comprises in combination, bristles, guide tube means and a source container from which a viscous substance is forced through apertures disposed near the bristles to the surface thereof. The flow of the viscous substance to the bristles is manually controlled by means of a knob disposed on the outside surface of a main shaft. An extension end of the container is provided to contain the toothbrush bristles and may be configurated as a toothbrush head. An opposite end of the toothbrush head includes a knob which is disposed for advancing a follower member which serves to force the viscous substance to the opening of the aperture which permits the viscous substance to surface to the bristles. At the forward end of the main shaft which contains the follower member, there is disposed a plug which permits closure of the open aperture thereby avoiding danger of leakage of the viscous substance during non-usage periods.
A device which comprises in combination, a brush-head disposed onto a handle portion, said handle portion having a container for dispensing a viscous material through a passage therebetween, said brush-head having bristles projecting therefrom, an aperture disposed in the brush-head relative the bristles and in communication with said passage, a partially threaded shaft disposed in the container and passage, said shaft having a plug movably disposed to open and close said aperture, said aperture being disposed perpendicular to the direction of travel of the plug, the aperture being disposed through the wall of the brush-head containing the bristles, said plug being disposed for limited open and close movement in the area of the aperture and within a channel positioned into the brush-head, a follower movable on said partially threaded shaft for forcing the viscous material from the container and to said passage, a knob externally disposed on the container, and means interconnecting said knob and said shaft whereby upon rotation of said knob, said plug and said follower are moved.
