An oral care implement comprises a handle having a container containing oral care fluid, A head includes tooth cleaning elements and a fluid outlet to output fluid into the vicinity thereof. A manually actuatable pump mechanism in the handle between the container and fluid outlet is connected thereto by respective first and second conduits. The pump mechanism comprises a chamber having an inlet connected to the first conduit, an outlet connected to the second conduit, and an actuatable valve mechanism for selectively opening the inlet and outlet respectively to cause fluid flow into and out of the chamber. The mechanism comprises first and second valve elements and a deformable actuator connected to the first and second valve elements. A wall which defines at least a part of the chamber is adapted to be manually moved to operate the valve mechanism.
An oral care implement comprising a handle portion, a container located in the handle portion and containing an oral care fluid, a head portion including a plurality of tooth cleaning elements, a fluid outlet in the head portion for outputting the oral care fluid into the vicinity of at least one of the tooth cleaning elements, and a manually actuatable pump mechanism is located in the handle portion between the container and the fluid outlet, the pump mechanism being connected to the container and the fluid outlet by respective first and second conduits, wherein the pump mechanism comprises a chamber having an inlet connected to the first conduit and an outlet connected to the second conduit, an actuatable valve mechanism for selectively opening the inlet and outlet respectively to cause fluid flow into the chamber from the first conduit and out of the chamber into the second conduit, the actuatable valve mechanism comprising a first valve element for selectively closing or opening the inlet, a second valve element for selectively opening or closing the outlet and a deformable actuator connected to the first and second valve elements, and a wall which defines at least a part of the chamber and is adapted to be manually moved to operate the actuatable valve mechanism.
