Abstract
A dispensing toothbrush includes a toothpaste filled reservoir handle which is attached to a hollow neck which is integral with a hollow brush head. A piston is movable within the reservoir handle for pushing toothpaste toward the hollow neck by way of a suction plunger. A plunger actuating button is connected to the suction plunger which forms first and second chambers in communication with the reservoir handle and the hollow neck. Depressing the plunger button depresses the suction plunger and pushes toothpaste through the hollow neck and a hole in the brush head onto the brush bristles. A vented cover is disposed over the brush head and a floss dispenser is attached to the reservoir handle opposite the end which is attached to the hollow neck.
Claims16
A toothpaste dispensing toothbrush, comprising in combination:
- a hollow brush head forming a hole;
- a hollow neck affixed to the hollow brush head and in open communication therewith;
- a reservoir handle attached to the hollow neck and in open communication therewith for containing toothpaste to be dispensed through the hollow neck and the hole in the brush head;
- a piston movable within the reservoir handle for pushing the toothpaste toward the hollow neck;
- a suction plunger connected between and in open communication with the reservoir handle and the hollow neck;
- a plunger button, wherein depressing the plunger button depresses the suction plunger and the suction plunger returns to the undepressed state when the plunger button is released, thereby pulling the piston toward the hollow neck and pushing the toothpaste through the neck to the hole in the brush head;
- a base forming a hole;
- a flip lid cover cap hingedly connected to the base;
- a center post locking pin affixed to the flip lid cover cap for engaging the hole formed in the base;
- a center post having at least one hollow end and affixed to the base to receive a floss spool;
- and
- a floss spool locking cap for inserting into the hollow end of the center post to prevent the floss spool from being removed or falling off while allowing the spool to spin freely upon activation of pulling the floss string.
