<p>A dentifrice dispensing toothbrush stores dentifrice material in its handle (8) and deposits a controlled quantity directly onto the top of the brush surface (40). The toothbrush comprises: a housing (4) which includes the handle, a reservoir (12) situated within the housing, a brush (2), and a pumping means which causes a controlled quantity of dentifrice material to be pumped from the reservoir (12) through a channel (34) and a movable applicator (6) and thereafter to be deposited onto the brush surface (40). The applicator can be positioned in either a depositing or non-depositing relationship with the brush surface. No dentifrice can be pumped from the reservoir when the applicator is in a non-depositing relationship with the brush surface, thus preventing the accidental discharge of dentifrice. The toothbrush is operated by depressing the brush member (2) which causes dentifrice material to be pumped from the reservoir (12). This is coupled with a simultaneous action of extending the applicator (6) to dispense a controlled portion of dentifrice material directly onto the top surface (40) of the brush. The toothbrush can be conveniently and efficiently operated with one hand. Its features make it particularly suitable for use by the physically handicapped.</p> |
