Abstract
A battery-powered toothbrush has an elongated housing shaped to be grasped by the human hand. The housing encloses a battery-energized motor which drives a brush shaft that has a stub projecting through a nose of the housing and upon which in use a brush is mounted. A generally tubular housing shell confines the battery, motor and shaft. An upper half shell is of a U-shaped exterior cross section over a substantial portion of its length, while a lower half shell is mated to the upper half shell in definition of the housing and is of semi-cylindrical exterior cross-section over a like substantial portion of its length. The distance along those substantial portions approximates the width of the adult human hand. The shaft is offset downwardly from the longitudinal geometric axis. All shell portions of different diameter merge smoothly into other portions of the shell.
