CLAIMS

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 therefrom;

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 comprises a first valve downstream of the reservoir, a second valve downstream of the first valve and upstream of the fluid outlet, and one of the first and second valves circumferentially surrounds the other of the first and second valves.

2. The oral care implement of claim 1, wherein one of the first and second valves comprises an umbrella check valve.

3. The oral care implement of claim 2, wherein the first valve comprises the umbrella check valve.

4. The oral care implement of claim 2 or claim 3, wherein the other of the first and second valves comprises one of a diaphragm check valve, a ball check valve, a swing check valve, a duckbill check valve, and an umbrella check valve.

5. The oral care implement of any preceding claim, wherein each of the first and second valves comprises a check valve.

6. The oral care implement of any preceding claim, further comprising a base having first and second holes extending therethrough along respective flow axes, wherein each of the flow axes is at between 45 and 90 degrees to a longitudinal axis of the oral care implement, and wherein each of the first and second valves selectively blocks a respective one of the first and second holes; optionally wherein each of the flow axes is substantially perpendicular to the longitudinal axis of the oral care implement.

7. The oral care implement of claim 6, wherein each of the flow axes is substantially perpendicular to a lateral axis of the oral care implement.

8. The oral care implement of any preceding claim, wherein the pump comprises a unitary component comprising the first and second valves.

9. The oral care implement of claim 8, wherein the unitary component is formed of a resilient material, such as an elastomeric material, such as an elastomer, a thermoplastic elastomer, or styrene-ethylene/butylene-styrene.

10. The oral care implement of any preceding claim, wherein the pump comprises a chamber of variable volume downstream of the first valve and upstream of the second valve.

11. The oral care implement of any preceding claim, wherein the pump comprises a diaphragm pump.

12. The oral care implement of claim 11, comprising a thumb grip surface on the handle, wherein the thumb grip surface is unitary with a movable diaphragm of the diaphragm pump.

13. The oral care implement of any preceding claim, wherein the oral care fluid is stored in the reservoir.

14. The oral care implement of any preceding claim, wherein the reservoir is in the handle.

15. The oral care implement of any preceding claim, wherein the reservoir is comprised in the body and forms the handle.

16. The oral care implement of any preceding claim, wherein the reservoir is detachably connected to the body.

17. The oral care implement of any preceding claim, wherein the reservoir is transparent or translucent.

18. The oral care implement of any preceding claim, wherein the oral care fluid comprises one or more oral care agents selected from the group consisting of: antibacterial agents; oxidative or whitening agents; enamel strengthening or repair agents; tooth erosion preventing agents; tooth anti-sensitivity ingredients; gum health actives; nutritional ingredients; tartar control or anti-stain ingredients; enzymes; sensate ingredients; caries or plaque disclosing agents; flavors or flavor ingredients; breath freshening ingredients; oral malodor reducing agents; anti-attachment agents or sealants; diagnostic solutions; occluding agents, dry mouth relief ingredients; catalysts to enhance the activity of any of these agents; colorants or aesthetic ingredients; and combinations thereof.

19. The oral care implement of any preceding claim, wherein the oral care implement comprises a toothbrush.

20. A method of manufacturing an oral care implement having a pump, the method comprising:

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 one of the first and second valves circumferentially surrounds the other of the first and second valves.

21. The method of claim 20, wherein one of the first and second valves comprises an umbrella check valve.

22. The method of claims 20 or 21, wherein the fitting comprises press-fitting the unitary component to the body.

23. The method of claim 22, wherein the fitting comprises press-fitting the second valve in the second hole at a position at which the first valve blocks the first hole and the second valve blocks the second hole.

24. The method of any one of claims 20 to 23, wherein the first valve circumferentially surrounds the second valve.

25. The method of any one of claims 20 to 24, wherein the first valve comprises the umbrella check valve.

26. The method of any one of claims 20 to 25, wherein the other of the first and second valves comprises one of a diaphragm check valve, a ball check valve, a swing check valve, a duckbill check valve, and an umbrella check valve.

27. The method of any one of claims 20 to 26, wherein the unitary component is formed of a resilient material, such as an elastomeric material, such as an elastomer, a thermoplastic elastomer, or styrene-ethylene/butylene-styrene.

28. The method of any one of claims 20 to 27, comprising attaching a diaphragm to the body to define a chamber between the diaphragm, the body and the unitary component.
