Abstract:
An oral care implement having a body comprising a handle, a head having at least one oral care element extending therefrom, and at least one fluid outlet; a reservoir in the body and for storing an oral care fluid; and a pump in the body for pumping the oral care fluid from the reservoir towards the fluid outlet, wherein the pump is an umbrella check valve circumferentially surrounding a duckbill check valve. Alternatively, the invention is a method of manufacturing an oral care implement, including the steps of providing a body comprising a base having first and second holes extending therethrough; and fitting to the body a unitary component comprising first and second valves at a position at which the first valve blocks the first hole and the second valve blocks the second hole, wherein the first valve is an umbrella check valve that circumferentially surrounds the second valve.
