Dispensing toothbrush

Abstract

A dispensing toothbrush includes a hollow handle. Toothpaste is positioned within the handle. A piston is positioned within the handle below the toothpaste. A brush is affixed to the top of the handle. The brush has an internal channel in fluid communication with the handle that provides a way for toothpaste to exit the toothbrush. A ball valve is positioned within the channel for preventing toothpaste from inadvertently leaking from the toothbrush. A thumbscrew is rotatably secured to the handle. The thumbscrew includes a threaded rod positioned within the handle. The threaded rod is threadably engaged with the piston. A knob is affixed to the bottom of the threaded rod and is positioned outside of the handle. Rotating the knob causes the piston to be driven upwardly so as to push toothpaste from the handle, past the ball valve, and from the brush.
