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 having an internal reservoir configured for containing a fluid. A dispensing orifice in the housing is in fluid communication with the reservoir. A fluid delivery system comprises a ratchet rod extending into the reservoir, an actuator operably coupled to the ratchet rod for imparting movement thereto, and a plunger assembly operably coupled to the ratchet rod and axially movable within the housing by activation of the actuator. The plunger assembly forms a selectively-positionable end wall of the reservoir. The plunger assembly comprises an outer cup seal slidably engaged with the housing and an inner plunger disposed at least partially in the outer cup seal. The plunger includes a pawl movably engaged with the ratchet rod. Activation of the actuator moves the plunger assembly in a first direction and dispenses the fluid from the reservoir via the orifice.
