Oral care system

摘要

An oral care system comprising a toothbrush and a dispenser detachably coupled to the toothbrush. The dispenser comprises a housing forming an internal cavity extending along a longitudinal axis. An elevator is disposed within the internal cavity that hermetically separates the internal cavity into a reservoir for containing a fluid and a chamber. The elevator comprises an outer surface forming an end wall of the reservoir and an inner surface forming an end wall of the chamber. The elevator is non-rotatable with respect to the housing. A dispensing orifice is in the housing for dispensing the fluid from the reservoir. A drive screw in the chamber is operably coupled to an actuator. The drive screw and the actuator are rotatable with respect to the housing. The drive screw does not penetrate through the outer surface of the elevator into the reservoir. An extension member has a first end coupled to the elevator and a second end threadily coupled to the drive screw. The extension member is non-rotatable with respect to the housing. A 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.
