Abstract

An oral care implement having a head with a soft tissue cleaner disposed on a second side thereof. In one embodiment, the invention can be an oral care implement comprising: a handle; a head attached to the handle and having a first side and a second side; a plurality of tooth cleaning elements attached to the first side of the head; and a soft tissue cleaner disposed on the second side of the head, the soft tissue cleaner including a first portion comprising a plurality of projections and a second portion comprising a plurality of bristles.

Claims

1. An oral care implement comprising:

a handle;

a head attached to the handle and having a first side and a second side opposite the first side;

a plurality of tooth cleaning elements extending from the head in a direction away from the first side; and

a soft tissue cleaner disposed on the second side of the head, the soft tissue cleaner including;

(1) a first portion comprising a first plurality of projections formed of an elastomeric material and extending in a direction away from the second side of the head;

(2) a second portion comprising a plurality of bristles extending in the direction away from the second side of the head; and

(3) a third portion comprising a second plurality of the projections extending in the direction away from the second side of the head, wherein the second portion is located between the first and third portions.

2. The oral care implement of claim 1 wherein the first portion of the soft tissue cleaner is a distal portion of the soft tissue cleaner and the third portion of the soft tissue cleaner is a proximal portion of the soft tissue cleaner.

3. The oral care implement of claim 1 wherein the plurality of bristles extend in the direction away from the second side of the head a height that is between 1 mm to 6 mm.

4. The oral care implement of claim 1 further comprising a vibratory device for imparting vibrations to the head.

5. The oral care implement of claim 1 wherein the plurality of bristles are bundled together into a plurality of tufts, each of the plurality of tufts having a width that is between 0.8 mm to 2.2 mm.

6. The oral care implement of claim 1 wherein the plurality of bristles are filament bristles.

7. The oral care implement of claim 1 wherein the plurality of bristles are movable in opposite directions normal to the second side.

8. An oral care implement comprising:

a handle;

a head attached to the handle and having a first side and a second side opposite the first side;

a plurality of tooth cleaning elements extending from the head in a direction away from the first side; and

a soft tissue cleaner disposed on the second side of the head, the soft tissue cleaner including;

(1) a first portion comprising a first plurality of projections extending in a direction away from the second side of the head;

(2) a second portion comprising a plurality of bristles extending in the direction away from the second side of the head; and

(3) a third portion comprising a second plurality of projections extending in the direction away from the second side of the head, the second portion being located between the first and third portions;

each of the plurality of bristles having a longitudinal axis and being movable in the direction of its longitudinal axis.

9. The oral care implement of claim 8 wherein the first plurality of the projections of the first portion are integrally formed with the head.

10. The oral care implement of claim 8 wherein the plurality of bristles extend in the direction away from the second side of the head a first height;

and the plurality of tooth cleaning element comprises bristles that extend in the direction away from the first side of the head a second height, the second height being greater than the first height.

11. The oral care implement of claim 8 wherein the plurality of bristles are movable in opposite directions towards and away from the second side.
