Patent ID: 7401373

Claim:
A disposable oral solution dispenser apparatus for attachment to a pre-assembled, self-contained, reusable powered toothbrush handle having a closed front end and having a drive coupling disposed thereon, the apparatus comprising: a housing adapted for releasable attachment to the handle, the housing extending alongside, and parallel to, at least a portion of the length of the handle, said housing being adapted to receive a consumable cartridge containing the oral solution; a manually-operated dispensing pump connected to said housing for moving the oral solution from the cartridge; an outlet nozzle connected to the dispensing pump and adapted to permit movement of the oral solution from said pump; and a head comprising a longitudinally extending stem having a distal end and a proximal end, the distal end of the stem having bristles thereon and the proximal end of the stem being adapted to releasably interconnect with the handle, the stem having a length sufficient to significantly space the bristles from the handle, the stem having a passageway extending between a distal opening located on the distal end of the stem adjacent to the bristles and a proximal opening located on the proximal end of the stem, the proximal end of the stem releasably interconnecting with the drive coupling of the handle such that the drive coupling of the handle can move the stem and hence the bristles, and the proximal end of the stem releasably interconnecting the proximal opening of the passageway with the outlet nozzle of the handle for delivering the oral solution from the cartridge to the bristles; wherein said housing is adapted to slidably receive the handle therein; wherein said housing is provided with a spring lock for releasably locking the handle in said housing.
