An oral care system comprising: a toothbrush ; and a dispenser detachably coupled to the toothbrush , the dispenser comprising: a housing forming an internal cavity extending along a longitudinal axis (B-B); an elevator disposed within the internal cavity that hermetically separates the internal cavity into a reservoir for containing a fluid and a chamber , the elevator being non-rotatable with respect to the housing ; a dispensing orifice in the housing for dispensing the fluid from the reservoir ; an actuator ; a drive screw in the chamber and operably coupled to the actuator ; and an extension member having a first end coupled to the elevator and a second end threadily coupled to the drive screw , the extension member being non-rotatable with respect to the housing ; wherein the elevator comprises an outer surface forming an end wall of the reservoir , an inner surface forming an end wall of the chamber , a base portion and a plug portion extending axially from the base portion along the longitudinal axis (B-B) toward the dispensing orifice , the plug portion comprising an internal cavity having a closed top end and an open bottom end ; wherein the drive screw and the actuator are rotatable with respect to the housing , and wherein the drive screw does not penetrate through the outer surface of the elevator into the reservoir ; wherein the elevator further comprises an annular groove formed in the inner surface , the annular groove surrounding the open bottom end of the internal cavity , and the first end of the extension member and a flange of the first end of the extension member being disposed within the annular groove ; and wherein rotation of the actuator causes the elevator to axially advance along the drive screw in a first axial direction due to relative rotation between the drive screw and the extension member . a housing forming an internal cavity extending along a longitudinal axis (B-B); an elevator disposed within the internal cavity that hermetically separates the internal cavity into a reservoir for containing a fluid and a chamber , the elevator being non-rotatable with respect to the housing ; a dispensing orifice in the housing for dispensing the fluid from the reservoir ; an actuator ; a drive screw in the chamber and operably coupled to the actuator ; and an extension member having a first end coupled to the elevator and a second end threadily coupled to the drive screw , the extension member being non-rotatable with respect to the housing ; wherein the elevator comprises an outer surface forming an end wall of the reservoir , an inner surface forming an end wall of the chamber , a base portion and a plug portion extending axially from the base portion along the longitudinal axis (B-B) toward the dispensing orifice , the plug portion comprising an internal cavity having a closed top end and an open bottom end ; wherein the drive screw and the actuator are rotatable with respect to the housing , and wherein the drive screw does not penetrate through the outer surface of the elevator into the reservoir ; wherein the elevator further comprises an annular groove formed in the inner surface , the annular groove surrounding the open bottom end of the internal cavity , and the first end of the extension member and a flange of the first end of the extension member being disposed within the annular groove ; and wherein rotation of the actuator causes the elevator to axially advance along the drive screw in a first axial direction due to relative rotation between the drive screw and the extension member . <EOS>
