Abstract

An oral care implement including an elastomeric component that includes a bumper portion that forms a distal-most section of the peripheral surface and a wall portion located along a distal-most section of the perimeter edge and protruding above the front surface. The wall portion may include a first ramped portion, an apex portion, and a second ramped portion. The wall portion may include a plurality of spaced-apart ridges protruding from an outer surface of the bumper portion and an outer surface of the wall portion. An oral care implement is disclosed that includes a soft tissue cleanser having a plurality of protuberances of differing heights.

Claims

1. An oral care implement comprising:

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

an elastomeric component including a bumper portion that forms a distal-most section of the peripheral surface and a wall portion located along a distal-most section of the perimeter edge and protruding above the front surface;

the wall portion extending along the perimeter edge in a continuous manner from a first point of the perimeter edge to a second point of the perimeter edge, the first and second points located on opposite sides of the longitudinal axis; and

the wall portion comprises a first ramped portion, an apex portion, and a second ramped portion, the apex portion disposed between the first and second ramped portions; and

wherein the wall portion has a maximum height at a third point of the perimeter edge located between the first and second points, the third point located on the longitudinal axis and on the apex portion.

2. The oral care implement according to claim 1 further comprising:

the first ramped portion extending from the first point to a fourth point of the perimeter edge, the fourth point located between the first and third points, the height of the first ramped portion of the wall portion increasing from the first point to the fourth point; and

the second ramped portion extending from the second point to a fifth point of the perimeter edge, the fifth point located between the second and third points, the height of the second ramped portion of the wall portion increasing from the second point to the fifth point.

3. The oral care implement according to claim 2 further comprising:

the apex portion extending from the fourth point to the fifth point, the apex portion having a substantially constant height from the fourth point to the fifth point.

4. The oral care implement according to claim 1 further comprising:

the first ramped portion extending from the first point to the third point, the height of the first ramped portion of the wall portion increasing from the first point to the third point; and

the second ramped portion extending from the second point to the third point, the height of the second ramped portion of the wall portion increasing from the second point to the third point.

5. The oral care implement according to claim 1 wherein a remaining portion of the perimeter edge is free of the wall portion.

6. The oral care implement according to claim 1 wherein the wall portion is free of through-holes.

7. The oral care implement according to claim 1 wherein elastomeric component further comprises a plurality of spaced-apart ridges protruding from an outer surface of the bumper portion and an outer surface of the wall portion.

8. The oral care implement according to claim 1 wherein the elastomeric component further comprises a soft tissue cleanser on the rear surface of the head, the soft tissue cleanser comprising a plurality of protuberances.

9. The oral care implement according to claim 1 wherein the wall portion and a transverse line drawn between the first and second points of the perimeter edge collectively define a distal-most area of the front surface of the head;

and wherein the plurality of tooth cleaning elements comprises a plurality of distal tooth cleaning elements extending from the distal-most area of the front surface, and wherein the wall portion has a maximum height that is less than or equal to one half of a height of a shortest one of the plurality of distal tooth cleaning elements.

10. An oral care implement comprising:

a handle; and

a head extending along a longitudinal axis from a proximal end to a distal end, the head comprising;

a front surface;

a rear surface;

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

a soft tissue cleanser on the rear surface of the head;

the soft tissue cleanser comprising;

a plurality of first protuberances protruding from the rear surface of the head and arranged in a first annular zone on the rear surface, each of the first plurality of protuberances having a height measured from the rear surface of the head to a free end of each of the first plurality of protuberances having a height between a first predetermined height and a second predetermined height, the second predetermined height being greater than the first predetermined height;

a plurality of second protuberances protruding from the rear surface of the head and arranged in a second annular zone on the rear surface, the first annular zone surrounding the second annular zone, each of the second plurality of protuberances having a height measured from the rear surface of the head to a free end of each of the second plurality of protuberances, the height between the second predetermined height and a third predetermined height, the third predetermined height being greater than the second predetermined height; and

a plurality of third protuberances protruding from the rear surface of the head and arranged in a third zone on the rear surface, the second annular zone surrounding the third zone, each of the third plurality of protuberances having a height measured from the rear surface of the head to a free end of each of the third plurality of protuberances, the height between the third predetermined height and a fourth predetermined height, the fourth predetermined height being greater than the third predetermined height.

11. The oral care implement according to claim 10 wherein the free ends of the first, second and third plurality of protuberances collectively form a convex side profile and a convex top profile.

12. The oral care implement according to claim 10 wherein the plurality of first protuberances comprise first conical nubs, the plurality of second protuberances comprise second conical nubs, and the plurality of third protuberances comprise third conical nubs.

13. The oral care implement according to claim 10 wherein the plurality of first protuberances comprise protuberances having a plurality of different heights between the first and second predetermined heights;

wherein the plurality of second protuberances comprise protuberances having a plurality of different heights between the second and third predetermined heights; and

wherein the plurality of third protuberances comprise protuberances having a plurality of different heights between the third and fourth predetermined heights.
