ABSTRACT:
A toothbrush and toothpaste system utilizing a container for the toothpaste which includes a chamber having a movable piston within the same. A spline is generally centrally located within the chamber with the movable piston circumjacently located relative to the spline. The piston is intended to contact toothpaste which is loaded within the chamber. The pistons movement is biased in one direction along the line. A head is connected to the container and includes a bristle structure usable as a toothbrush. The head includes a passageway which communicates with the adjacent chamber of the container and the bristle structure of the head. A valve separated by movement of the spline opens the passageway permitting communication between the chamber and the bristle structure. Springs means is also included for closing the valve relative to the container. The piston continually moves along the spline during the delivery of toothpaste to the bristle structure in only one direction within the chamber of the container.
