Toothpaste dispensing toothbrush

Abstract

A toothpaste dispensing toothbrush has a longitudinal, hollow, cylindrical housing, an open distal end, and an open proximal end. The distal end is tapered to a blunt, open extremity. The proximal end has a predetermined inside diameter. The cylindrical housing also has a transparent longitudinal window located along its outer surface. A toothbrush head is removably affixed to the distal end of the housing. A hollow, cylindrical toothbrush cartridge chamber has an open proximal end and an outside diameter smaller than the inside diameter of the housing proximal end, to facilitate insertion of the cartridge chamber into the proximal end of the housing. A movable piston is disposed in the cartridge chamber and a slidable button is located on the housing and connected to the movable piston. A dome cap is removably affixed to the proximal end of the cartridge chamber to retain toothpaste introduced into it. A dental floss container can be removably attached to the toothbrush and an LED light can be added to illuminate areas of the mouth being brushed.

What is claimed is: 
     
         1 . A toothbrush comprising:
 a) a longitudinal, hollow, cylindrical housing having an outer surface, an open distal end, and an open proximal end, said distal end being tapered to a blunt, open extremity, and said proximal end having a predetermined inside diameter, said cylindrical housing further having a transparent longitudinal window located along said outer surface thereof;   b) a toothbrush head removably affixed to said distal end of said housing;   c) a hollow, cylindrical toothbrush cartridge chamber having an open proximal end and an outside diameter no greater than said inside diameter of said housing, to facilitate insertion of said cartridge chamber fully into said proximal end of said cylindrical housing;   d) a movable piston disposed in said cartridge chamber adapted to move along a path in said cylindrical housing;   e) a slidable button located on said outer surface of said housing and operatively connected to said movable piston; and   f) a dome cap removably affixed to said proximal end of said cartridge chamber to retain toothpaste introduced therein.   
     
     
         2 . The toothbrush in accordance with  claim 1 , wherein said removable dome cap is screwed on to said cartridge chamber.
