ABSTRACT:
A toothbrush having an elongate handle with an enlarged base end capable of supporting the toothbrush in an upright position and being hollow for storage of the bristle head or the like therein, includes an elongate shaft fixed at one end to the base and projecting axially therefrom. A tubular sleeve is axially slidable on the shaft and the shaft has bristle head retaining structure thereon for retaining a bristle head on the handle at the end thereof opposite the base end. The sleeve is normally biased toward the base end to a first position, whereat the bristle head retaining structure is engaged with the bristle head to hold it in position and the sleeve is movable away from the base end to a second position to move the bristle head to disengage it from the bristle head retaining structure. A finger operated sleeve actuator is slidable relative to the base end and shaft to engage the sleeve and move it to its second position, and a seal is engaged between the shaft and sleeve at the bristle head end.
