ABSTRACT:
A disposable toothbrush apparatus is provided having a head, a bristle cluster extending from the head and a hollow handle for defining a toothpaste storage chamber connected to the head. A manually actuatable pump assembly mounted for axial displacement at the distal end of the handle storage chamber is adapted to cause a predetermined amount of toothpaste in the chamber to be fed via a conduit to a nozzle opening in a surface of the head at the base of the bristle cluster. In an alternative embodiment, a refillable cartridge containing a fresh supply of toothpaste and the self-contained pump assembly is adapted to be fitted to the hollow handle.
