Abstract

Disclosed is an oral care implement comprising: a body having a head portion having a front side and a rear side, at least one cleaning element disposed at the front side of the head portion of the body, and a rim extending from the rear side of the head portion of the body, wherein the rim includes one or more weakened portions and extends along a perimeter region of the head portion of the body; and resilient material disposed at the rear side of the head portion of the body, wherein the rim is disposed around at least a portion of the resilient material.

First claim

What is claimed is:

1. An oral care implement, comprising:
a body having a head portion having a front side and a rear side, at least one cleaning element disposed at the front side of the head portion of the body, and a rim extending from the rear side of the head portion of the body and terminating at a distal end, wherein the rim includes one or more weakened portions and extends along a perimeter region of the head portion of the body; and
resilient material disposed at the rear side of the head portion of the body, wherein the rim is disposed around at least a portion of the resilient material, the resilient material filling the one or more weakened portions and covering an entirety of the distal end of the rim.

2. The oral care implement of claim 1 , wherein the rim and the rear side of the head portion of the body together define a basin.

3. The oral care implement of claim 2 , wherein at least a portion of the resilient material is disposed in the basin.

4. The oral care implement of claim 1 , wherein the head portion has a longitudinal axis, and wherein weakened portions of the rim are disposed at lateral sides of the head portion.

5. The oral care implement of claim 1 , wherein the head portion of the body has one or more grooves formed therein.

6. The oral care implement of claim 5 , wherein the, or each, groove is aligned with weakened portions of the rim disposed at opposite sides of the head portion.

7. The oral care implement of claim 1 , wherein the, or each, cleaning element extends through the head portion of the body, has a distal end at the front side of head portion of the body, and has a proximal end at the rear side of the head portion of the body.

8. The oral care implement of claim 7 , wherein plural cleaning elements are disposed at the front side of the head portion of the body, and wherein each of the plural cleaning elements has a distal end at the front side of the head portion of the body and a proximal end at the rear side of the head portion of the body.

9. The oral care implement of claim 8 , wherein the respective proximal ends of the plural cleaning elements are fused together at the rear side of the head portion of the body.

10. The oral care implement of claim 8 , wherein the respective proximal ends of the plural cleaning elements are fixed to the rear side of the head portion of the body.

11. The oral care implement of claim 7 , wherein the resilient material contacts the proximal end of the, or each, cleaning element.

12. The oral care implement of claim 11 , wherein the resilient material is fixed to the proximal end of the, or each, cleaning element.

13. The oral care implement of claim 1 , wherein the resilient material is fixed to the head portion of the body.

14. The oral care implement of claim 1 , wherein the resilient material defines part of an exterior surface of the implement.

15. The oral care implement of claim 1 , wherein a thickness of the head portion of the body measured in a direction extending between the front and rear sides of the head portion of the body is less than or equal to a thickness of the resilient material measured in the same direction.

16. The oral care implement of claim 1 , wherein the, or each, weakened portion has a cross sectional area that is less than a cross sectional area of each of two adjacent portions of the rim between which the weakened portion is disposed.

17. The oral care implement of claim 1 , wherein the rim has varying height in a direction in which the rim extends from the rear side of the head portion of the body.

18. The oral care implement of claim 1 , wherein the rim is discontinuous.

19. The oral care implement of claim 1 , wherein the rim extends along a perimeter of the head portion of the body.

20. The oral care implement of claim 1 , wherein the rim is offset from a perimeter of the head portion of the body.

21. The oral care implement of claim 1 , wherein the rim is unitary with the head portion of the body.

22. The oral care implement of claim 1 , wherein the head portion of the body is flexible.

23. An oral care implement, comprising:
a body having a head portion having a front side and a rear side, at least one cleaning element disposed at the front side of the head portion of the body, and a rim extending from the rear side of the head portion of the body and terminating at a distal end, wherein the rim includes one or more weakened portions and extends along a perimeter region of the head portion of the body; and
wherein the rim and the rear side of the head portion of the body together define a basin, the rear side of the head forming a floor of the basin;
resilient material disposed at the rear side of the head portion of the body, at least a portion of the resilient material disposed in the basin, wherein the rim is disposed around at least a portion of the resilient material; and
wherein the one or more weakened portions comprises a gap formed into the rim that extends from the distal end of the rim and terminates at the floor of the basin.

24. An oral care implement, comprising:
a body having a head portion having a front side and a rear side, at least one cleaning element disposed at the front side of the head portion of the body, and a rim extending from the rear side of the head portion of the body, wherein the rim includes one or more weakened portions and extends along a perimeter region of the head portion of the body; and
resilient material disposed at the rear side of the head portion of the body, wherein the rim is disposed around at least a portion of the resilient material;
wherein the rim has a substantially constant thickness from the rear side of the head portion of the body to a distal end of the rim.
