Abstract: An oral care implement with fluid dispensing system includes a head, handle, and intermediate neck. The head comprises plural tooth cleaning elements. A reservoir containing oral care fluid is fluidly coupled to an elastomeric valve nested between a pair of longitudinally spaced protective lamellas on the head. A depressible actuator button operates to dispense the oral care fluid from the reservoir through the valve to the tooth cleaning elements. The protective lamellas formed of elastomeric material are foldable to alternating cover the valve to prevent ingress of external fluids in the oral cavity of the user into the valve to minimize fouling of the fluid dispensing system. Laterally open areas between the lamella allow the oral care fluid to migrate outwards to the tooth cleaning elements. To control the dosage of oral care fluid dispensed, a modular system comprising interchangeable spacer inserts is usable to change and customize the dosage.
