Abstract

An oral care implement having a body having a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending therefrom; a reservoir in the body and for storing an oral care fluid; and a supply mechanism connected to the body, the supply mechanism having a user-operable selector comprising a cam, and an actuator comprising a follower in contact with the same, the actuator operable to cause the oral care fluid to flow from the reservoir towards the fluid outlet, and wherein the cam is movable relative to the body to cause movement of the follower relative to the body and thereby operate the actuator.

First claim

What is claimed is:

1. An oral care implement, comprising:
a body comprising a handle, a head at an end of the handle, and at least one fluid outlet, the head having at least one oral care element extending from a front side of the body;
a reservoir in the body storing an oral care fluid; and
a supply mechanism connected to the body, the supply mechanism comprising:
a user-operable selector comprising a cam on the front side of the body; and
an actuator comprising a flow passage and a follower, the follower in contact with the cam, the actuator operable to cause the oral care fluid to flow from the reservoir towards the fluid outlet through the flow passage;
wherein the cam comprises a planar first surface in contact with a planar second surface of the follower, the first surface being parallel to the second surface;
wherein the cam is movable relative to the body to cause movement of the follower relative to the body and thereby operate the actuator; and
wherein the planar second surface of the follower is located between the front side of the body and the flow passage of the actuator.

2. The oral care implement of claim 1 , wherein the cam is a linear cam.

3. The oral care implement of claim 1 , wherein each of the cam and the follower comprises a surface in contact with the other of the cam and the follower.

4. The oral care implement of claim 1 , wherein the selector comprises a user-contactable surface forming a portion of an exterior surface of the oral care implement, and wherein the user-contactable surface is fixed relative to the cam, wherein the selector comprises a unitary component comprising the user-contactable surface and the cam.

5. The oral care implement of claim 1 , wherein the selector defines a portion of a fluid passageway extending to the fluid outlet.

6. The oral care implement of claim 1 , wherein the follower defines a portion of a fluid passageway extending to the fluid outlet.

7. The oral care implement of claim 1 , wherein the cam is movable relative to the body along a first axis and the follower is movable relative to the body along a second axis that is substantially perpendicular to the first axis.

8. The oral care implement of claim 1 , wherein the follower is movable relative to the body along an axis substantially parallel to a longitudinal axis of the oral care implement.

9. The oral care implement of claim 1 , wherein the supply mechanism comprises a first valve connected to the actuator, and the actuator is operable to cause movement of the first valve relative to the reservoir between a first position, at which the first valve isolates the reservoir from downstream of the valve, and a second position, at which the reservoir is in fluid communication with downstream of the first valve.

10. The oral care implement of claim 9 , wherein the supply mechanism comprises a biasing device that biases the supply mechanism to a state in which the first valve is at the first position.

11. The oral care implement of claim 9 , wherein the reservoir is comprised in an aerosol can, the actuator is connected to the first valve via a valve stem of the aerosol can, and the actuator is operable to cause movement of the valve stem relative to the reservoir, thereby to cause movement of the first valve relative to the reservoir between the first position and the second position.

12. The oral care implement of claim 1 , wherein the oral care fluid is stored in the reservoir with a propellant comprising at least one of a liquefied gas and a compressed gas.

13. The oral care implement of claim 1 , wherein the supply mechanism comprises a pump for pumping the oral care fluid from the reservoir towards the fluid outlet, and wherein the actuator is operable to cause the pump to pump the oral care fluid from the reservoir towards the fluid outlet, wherein the pump comprises a first valve, a second valve downstream from the first valve, and a chamber between the first valve and the second valve.

14. The oral care implement of claim 13 , wherein the chamber is of variable volume.

15. The oral care implement of claim 1 , wherein the oral care fluid is stored in the reservoir at greater than atmospheric pressure.

16. The oral care implement of claim 1 , wherein the reservoir is in the handle.

17. The oral care implement of claim 1 , wherein the reservoir is detachably connected to the body.

18. The oral care implement of claim 1 , wherein the oral care implement comprises a toothbrush.
