Abstract

An oral hygiene implement includes a cleaning element carrier and a body. The body has a proximal end and a distal end. The cleaning element carrier has a first area and a second area wherein the second area is disposed inboard of the first area. The first area is attached to the body while the second area is unattached to the body. A bending element is disposed between the first area and the second area, thereby allowing the second area to bend/flex while the first area stays fixed to the body.

First claim

What is claimed is:

1. An oral hygiene implement comprising:
a body having a distal end, a proximal end, and a longitudinal axis;
a secondary cleaning surface;
a cleaning or gum massaging element carrier having;
a first carrier member having a first proximal area and a first distal area; and
a second carrier member having a second proximal area and a second distal area,

a gap between a lower surface of the cleaning or gum massaging element carrier and a top surface of the secondary cleaning surface;
wherein the first proximal area and the second proximal area are attached to the body such that the first carrier member and the second carrier member extend toward the body;
wherein the first carrier member and the second carrier member are configured such that the first distal area and the second distal area are unattached to the body and the first carrier member and second carrier member defining an intermediate opening there between;
wherein the secondary cleaning surface outwardly extends from the longitudinal axis in a lateral direction substantially perpendicular to the longitudinal axis, the secondary cleaning surface overlapping the lower surface of the cleaning or gum massaging carrier in the lateral direction; and
the oral hygiene implement further comprising an elastomeric member attached to the body and extending through the intermediate opening.

2. The oral hygiene implement of claim 1 wherein the elastomeric member comprises a continuous outer wall forming an outer wall surface and a plurality of flaps extending from an intermediate surface, wherein at least one of the plurality of flaps are taller than the outer wall surface.

3. The oral hygiene implement of claim 2 , wherein the elastomeric member further comprises a plurality of bristles extending through the intermediate opening.

4. The oral hygiene implement of claim 2 wherein the elastomeric member comprises a base portion, a pair of side walls attached to the base portion, each side wall comprising a peak and a valley, a plurality of flaps attached to the base portion and disposed between the pair of side walls, wherein the side walls and the flaps form at least one reservoir.

5. The oral hygiene implement of claim 1 wherein the elastomeric member supports cleaning elements.

6. An oral hygiene implement comprising:
a longitudinal axis, a lateral axis, and a transverse axis;
a body;
a secondary cleaning surface;
a first carrier member having a first proximal area and a first distal area;
a second carrier member having a second proximal area and a second distal area,
a gap between a lower surface of the first carrier member and the second carrier member and a top surface of the secondary cleaning surface;

wherein the first proximal area and the second proximal area are attached to the body such that the first carrier member and the second carrier member extend toward the body, wherein the first carrier member and the second carrier member are configured such that the first distal area and the second distal area are unattached to the body and can flex independently of one another;
wherein the secondary cleaning surface outwardly extends from the longitudinal axis in a lateral direction substantially perpendicular to the longitudinal axis, the secondary cleaning surface overlapping the lower surface of the first carrier member and the second carrier member in the lateral direction.

7. The oral hygiene implement of claim 6 wherein the first distal area, second distal area, or both can flex in a direction generally parallel to the transverse axis.

8. The oral hygiene implement of claim 6 wherein the first distal, second distal area, or both can flex in a direction generally parallel to the lateral axis.

9. The oral hygiene implement of claim 6 wherein at least one of the first distal area or the second distal area can flex in a direction generally parallel to the transverse axis and can flex in a direction generally parallel to the lateral axis.

10. The oral hygiene implement of claim 6 , wherein the first carrier member and the second carrier member form an intermediate opening there between, wherein the oral hygiene implement further comprises an intermediate member attached to the body and extending through the intermediate opening.

11. An oral hygiene implement comprising:
a body having a distal end, a proximal end, and a longitudinal axis;
a cleaning element carrier having;
a first carrier member having a first proximal area and a first distal area; and
a second carrier member having a second proximal area and a second distal area,

a gap between a lower surface of the cleaning element carrier and a top surface of the secondary cleaning surface;
wherein the first proximal area and the second proximal area are attached to the body such that the first carrier member and the second carrier member extend toward the body;
wherein the first carrier member and the second carrier member are configured such that the first distal area and the second distal area are unattached to the body,
wherein the first and second distal areas are disposed inboard of the first and second proximal areas;
a bending element disposed between the first proximal area and the first distal area and the second proximal area and the second distal area thereby allowing the first and second distal areas to move while the first and second proximal areas stay fixed; and
wherein the secondary cleaning surface outwardly extends from the longitudinal axis in a lateral direction substantially perpendicular to the longitudinal axis, the secondary cleaning surface overlapping the lower surface of the cleaning element carrier in the lateral direction.

12. The oral hygiene implement of claim 11 wherein the bending element is a weakened area.

13. The oral hygiene implement of claim 11 wherein the cleaning element carrier is made from a first material and the bending element comprises a second material, and wherein the second material is different from the first material.

14. The oral hygiene implement of claim 11 wherein the bending element is integral with the cleaning element carrier.

15. The oral hygiene implement of claim 11 wherein the bending element is discrete and is attached to the cleaning element carrier.

16. An intermediate member for use in the oral hygiene implement of claim 1 , the intermediate member comprising:
a base portion;
a pair of side walls attached to the base portion, each side wall comprising a peak and a valley; and
a plurality of flaps attached to the base portion and disposed between the pair of side walls, wherein the side walls and the flaps form at least one reservoir, and wherein the flaps and the side walls are separated by a gap.

17. The intermediate member of claim 16 wherein the flaps are angled with respect to the base portion.

18. The intermediate member of claim 16 wherein the side walls are wavy.
