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 head having tooth cleaning elements projecting from a front side of the head, the head having a longitudinal axis;

a cleanser for cleansing soft tissue in the mouth, the cleanser located on a rear side of the head, the cleanser including;

a plurality of elongate base portions fixed to the head, the elongate base portions arranged transversely on the rear side of the head in a spaced-apart manner;

a plurality of spaced-apart projections protruding outward from each of the elongate base portions for removal of microbial and other debris from the soft tissue; and

an elongate longitudinal portion connecting the elongate base portions;

the head being formed at least partially of a first material and the cleanser being formed of a second material which is different than the first material;

wherein the elongate longitudinal portion extends along the longitudinal axis of the head;

wherein each of the elongate base portions comprise a first portion that extends from the longitudinal axis in a first lateral direction, and a second portion that extends from the longitudinal axis in a second lateral direction opposite the first lateral direction; and

wherein the first and second portions of the elongate base portions have a concave shape facing a handle connected to the head.

2. An oral care implement according to claim 1 wherein the base portions and the projections are each comprised of an elastomeric material.

3. An oral care implement according to claim 1 which further includes an elongate ridge formed on the rear side of the head of the first material, the elongate ridge projecting from the rear side of the head.

4. An oral care implement according to claim 1 wherein the projections are generally columnar in shape.

5. An oral care implement according to claim 4 wherein each said projection includes an end surface remote from the rear side of the head that is inclined to the longitudinal axis of the head.

6. An oral care implement according to claim 1 wherein the elongate base portions, the elongate longitudinal portion and the projections are formed as a one-piece member.

7. An oral care implement according to claim 6 wherein the elongate base portions and the projections are each composed of an elastomeric material.

8. An oral care implement according to claim 1 wherein the elongate longitudinal portion of the cleanser extends onto the handle and forms a part of a grip.

9. An oral care implement according to claim 1 wherein the cleanser has a hardness within the range of about 8-35 Shore A hardness.

10. An oral care implement according to claim 1 wherein the elongate base portions are generally parallel to one another.
