Abstract

An oral care implement having a head with a soft tissue cleanser thereon. In one aspect, the invention can be an oral care implement including a handle and a head coupled to the handle, the head comprising a front surface; a rear surface opposite the front surface; a peripheral surface extending between the rear surface and the front surface; a first elastomeric soft tissue cleanser comprising a bumper portion that extends along the peripheral surface, the bumper portion comprising an undulating upper edge that includes a plurality of high points protruding above the rear surface and a plurality of low points located at or below the rear surface; and a plurality of tooth cleaning elements extending from the front surface.

Claims

1. An oral care implement comprising:

a handle; and

a head coupled to the handle, the head comprising;

a front surface;

a rear surface opposite the front surface;

a peripheral surface extending between the rear surface and the front surface;

a first elastomeric soft tissue cleanser comprising a bumper portion, the bumper portion comprising an undulating upper edge and an undulating lower edge that both extend along the peripheral surface of the head, the undulating upper edge forming a plurality of high points projecting outward from the rear surface in a direction opposite the front surface and the undulating lower edge forming a plurality of low points located adjacent the peripheral surface between the front surface and the rear surface; and

a plurality of tooth cleaning elements extending from the front surface.

2. The oral care implement according to claim 1 wherein the plurality of high points are spaced from the rear surface of the head in a direction opposite the plurality of tooth cleaning elements.

3. The oral care implement according to claim 1 wherein the first elastomeric soft tissue cleanser comprises a connecting portion on at least one of the rear surface of the head or a neck portion of the handle, the connecting portion and the bumper portion collectively forming an annular structure.

4. The oral care implement according to claim 1 wherein the head comprises a base formed of a hard plastic, the first elastomeric soft tissue cleanser coupled to the base.

5. The oral care implement according to claim 4 further comprising a second elastomeric soft tissue cleanser coupled to the base on the rear surface of the head, the second elastomeric soft tissue cleanser comprising a plurality of protuberances that extend from the rear surface, and the first and second elastomeric soft tissue cleansers being separate and distinct components from one another.

6. The oral care implement according to claim 5 wherein the base comprises an exposed annular surface that forms a portion of the rear surface of the head, the exposed annular surface located adjacent the peripheral surface and circumscribing the second elastomeric soft tissue cleanser.

7. The oral care implement according to claim 5 wherein the base comprises a basin, the second elastomeric soft tissue cleanser comprising a pad portion disposed in the basin.

8. The oral care implement according to claim 5 wherein the base comprises a channel, at least a portion of the first elastomeric soft tissue cleanser disposed in the channel.

9. The oral care implement according to claim 4 wherein the bumper portion comprises an undulating lower edge comprising a plurality of high points located on the peripheral surface and a plurality of low points located on the peripheral surface.

10. The oral care implement according to claim 9 wherein the base comprises a plurality of exposed side surface portions that form portions of the peripheral surface, the exposed side surface portions located between valleys of the undulating lower edge of the bumper portion, the valleys of the undulating lower edge comprising the low points of the undulating lower edge.

11. The oral care implement according to claim 9 wherein the high points of the undulating upper edge are aligned with the high points of the undulating lower edge;

and wherein the low points of the undulating upper edge are aligned with the low points of the undulating lower edge.

12. The oral care implement according to claim 1 wherein no portion of the first elastomeric soft tissue cleanser extends beyond the front surface of the head in a direction toward the front surface.

13. The oral care implement according to claim 1 wherein the low points of the undulating upper edge of the bumper portion are located on the peripheral surface and spaced a distance below the rear surface.

14. The oral care implement according to claim 1 wherein the peripheral surface and the rear surface intersect to form a perimeter of the rear surface of the head;

and wherein the bumper portion comprises a plurality of raised portions located along the perimeter that protrude above the rear surface, the raised portions comprising the high points.

15. The oral care implement according to claim 14 wherein the raised portions are arranged in a spaced-apart manner about the perimeter so as to at least partially circumscribe the rear surface.

16. An oral care implement comprising:

a handle;

a head coupled to the handle, the head comprising;

a front surface;

a rear surface opposite the front surface;

a peripheral surface extending between the rear surface and the front surface, the peripheral surface and the rear surface intersecting to form a perimeter of the rear surface of the head;

a base formed of a hard material, the base comprising an exposed annular surface that forms a portion of the rear surface of the head;

a first elastomeric soft tissue cleanser coupled to the base, the first elastomeric soft tissue cleanser comprising a bumper portion on the peripheral surface, the bumper portion comprising a plurality of lower portions on the peripheral surface and a plurality of raised portions projecting outward from the rear surface along the perimeter in a direction opposite the front surface;

a second elastomeric soft tissue cleanser coupled to the base on the rear surface of the head, the exposed annular surface of the base circumscribing the second elastomeric soft tissue cleanser, the second elastomeric soft tissue cleanser comprising a plurality of protuberances that extend from the rear surface;

the first and second elastomeric soft tissue cleansers being separate and distinct components from one another; and

a plurality of tooth cleaning elements extending from the front surface.

17. The oral care implement according to claim 16 wherein the raised portions of the bumper portion are ridges having a length measured along the perimeter and a width measured orthogonal to the length, the length being greater than the width;

and wherein the raised portions are arranged in a spaced-apart manner about the perimeter so as to at least partially circumscribe the rear surface.

18. The oral care implement according to claim 16 wherein the base comprises a basin, the second elastomeric soft tissue cleanser comprising a pad portion disposed in the basin.

19. The oral care implement according to claim 16 wherein the base comprises a channel, at least a portion of the first elastomeric soft tissue cleanser disposed in the channel.

20. An oral care implement comprising:

a handle; and

a head coupled to the handle, the head comprising;

a front surface;

a rear surface opposite the front surface;

a peripheral surface extending between the rear surface and the front surface;

a first elastomeric soft tissue cleanser comprising a bumper portion that extends along the peripheral surface, the bumper portion comprising an undulating upper edge that includes a plurality of high points and a plurality of low points, the plurality of high points projecting outward from the rear surface in a direction opposite the front surface, and the plurality of low points located adjacent the peripheral surface at or between the front surface and the rear surface; and

a plurality of tooth cleaning elements extending from the front surface;
