Abstract

See full text

The present invention discloses a powered or manual toothbrush having a polymer battery as a power source. The polymer battery contains no heavy metals, making it environmentally safe, and contains no alkaline, making it physically safe. The polymer battery is inexpensive and rechargeable, making it an economical power source for the toothbrush. The small size of the polymer battery saves space in the toothbrush housing, enabling the housing to be smaller and saving on materials of construction. The flexible nature of the polymer battery enables it to be shaped to fit into or around the periphery of the toothbrush housing design.
