Abstract

An oral care implement with a handle includes a head with a tissue cleanser. The tissue cleanser may be a pad composed of an elastomeric material. The pad is disposed on the head on a surface opposite the tooth cleaning elements. The tissue cleanser may include a plurality of nubs extending for cleaning between the papillae of the tongue. The tissue cleanser may include a plurality of conically shaped nubs. A tissue cleanser can be used to reduce oral malodor problems and remove oral epithelial cells.

Claims

1. An oral care implement comprising:

a handle;

a head coupled to the handle and having a plurality of protuberances extending therefrom, the protuberances each having a free end;

a tissue cleanser having a plurality of apertures exposing the free ends of the protuberances, and a plurality of projections for cleaning soft tissue surfaces in the mouth; and

a first group of arcuate segment tooth cleaning elements and a second group of arcuate segment tooth cleaning elements extending from one side of the head, wherein the tissue cleanser is mounted to an opposite side of the head.

2. The oral care implement according to claim 1, in which the projections include a plurality of nubs.

3. The oral care implement according to claim 2, in which the nubs are conically shaped.

4. The oral care implement according to claim 1, wherein the head includes a basin, and the protuberances and the tissue cleanser are positioned within the basin.

5. The oral care implement according to claim 1, wherein the first group and the second group of arcuate tooth cleaning elements comprise an elastomeric material and the tissue cleanser has a hardness of about 8–

25 Shore A.

6. An oral care implement, comprising:

a handle;

a head coupled to the handle and the head having a basin formed in one side thereof;

the basin having a base surface and a peripheral sidewall extending from the base surface, the sidewall having an exposed top surface, and the basin including a plurality of protruding members extending from the base surface, wherein at least two of the protruding members have a top portion raised above the base surface; and

an elastomeric tissue cleanser received in the basin, the tissue cleanser having a top surface being generally flush with the top surface of the sidewall, the tissue cleanser having at least two complementary openings for receiving the at least two protruding members therein and exposing the top portions thereof, and the tissue cleanser including a plurality of conical shaped nubs for cleaning soft tissue surfaces in the mouth.

7. The oral care implement according to claim 6, which further comprises a plurality of tooth cleaning elements extending from one side of the head, and wherein the tissue cleanser is mounted to an opposite side of the head.

8. The oral care implement according to claim 6, in which the nubs are disposed in longitudinal rows and transverse rows on the surface area of the tissue cleanser.

9. The oral care implement according to claim 8, in which adjacent transverse rows of nubs are in a staggered relationship.

10. The oral care implement according to claim 9, wherein the tissue cleanser has a nub density of about 150–

600 nubs per square inch.

11. The oral care implement according to claim 6, wherein the tissue cleanser has a nub density of about 150–

600 nubs per square inch.

12. The oral care implement according to claim 6, further comprising a first group of arcuate segment tooth cleaning elements and a second group of arcuate segment tooth cleaning elements extending from one side of the head, wherein the tissue cleanser is mounted to an opposite side of the head.

13. The oral care implement according to claim 12, wherein at least one group of the arcuate segment tooth cleaning elements comprises at least one bristle tuft.

14. The oral care implement according to claim 12, wherein at least one group of the arcuate segment tooth cleaning elements comprises at least one elastomeric member.

15. The oral care implement according to claim 12, wherein the groups of arcuate segment tooth cleaning elements comprise elastomeric walls and a bristle tuft is disposed within each of the arcuate segment groups of cleaning elements.
