Abstract

An oral care implement is disclosed that comprises a handle and a head. The head comprises a base structure having a front surface. A cleaning element carrier is provided that includes a top surface and a bottom surface. The cleaning element carrier is supported so that the bottom surface of the cleaning element carrier is spaced from the front surface of the base structure. At least a portion of the cleaning element carrier is movable relative to the base structure in a direction towards the front surface of the base structure. A plurality of first cleaning elements are mounted to the cleaning element carrier and extend from the top surface of the cleaning element carrier. A plurality of second cleaning elements are mounted to the base structure and extend from the front surface of the base structure and beyond the top surface of the cleaning element carrier.

Claims

1. An oral care implement comprising:

a handle;

a head having a proximal end coupled to the handle, a distal end, a longitudinal axis extending from the proximal end to the distal end, and a base structure having a front surface;

a cleaning element carrier having a top surface, a bottom surface, and lateral edges extending between the top and bottom surfaces, the cleaning element carrier supported so that an entirety of the bottom surface and the lateral edges of the cleaning element carrier are spaced from the front surface of the base structure, at least a portion of the cleaning element carrier movable relative to the base structure in a direction towards the front surface of the base structure;

a plurality of bristle tufts mounted to the cleaning element carrier and extending from the top surface of the cleaning element carrier; and

an elastomeric cleaning element mounted to the base structure and extending from the front surface of the base structure and beyond the top surface of the cleaning element carrier.

2. The oral care implement according to claim 1 wherein the plurality of bristle tufts are mounted to the cleaning element carrier via an anchor-free tufting process or an in-molded tufting process.

3. The oral care implement according to claim 1 wherein the plurality of bristle tufts terminate in first free ends at a first height from the front surface of the base structure and the elastomeric cleaning element terminates in a second free end at a second height from the front surface of the base structure;

and wherein the difference between the first and second heights is varied during movement of the cleaning element carrier in the direction toward the front surface of the base structure.

4. The oral care implement according to claim 3 wherein the cleaning element carrier is supported above the base structure by at least one pod extending from the base structure, and wherein the at least one pod is located on the longitudinal axis.

5. The oral care implement according to claim 4 wherein the at least one pod is located at the distal end of the head.

6. The oral care implement according to claim 5 wherein at least one of the plurality of first cleaning elements is not in transverse alignment with the elastomeric cleaning element;

and wherein at least another one of the plurality of first cleaning elements is in transverse alignment with the elastomeric cleaning element.

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

the plurality of bristle tufts mounted to the cleaning element carrier via an anchor-free tufting process or an in-molded tufting process;

the plurality of bristle tufts terminating in first free ends at a first height from the front surface of the base structure and the elastomeric cleaning element terminating in a second free end at a second height from the front surface of the base structure;

wherein the difference between the first and second heights is varied during movement of the cleaning element carrier in the direction toward the front surface of the base structure;

wherein the cleaning element carrier is supported above the base structure by at least one pod extending from the base structure; and

the at least one pod is located on the longitudinal axis and at the distal end of the head.

8. The oral care implement according to claim 7 wherein at least one of the plurality of first cleaning elements is not in transverse alignment with the elastomeric cleaning element;

and wherein at least another one of the plurality of first cleaning elements is in transverse alignment with the elastomeric cleaning element.

9. The oral care implement of claim 1, wherein the cleaning element carrier is elongated in the direction of the longitudinal axis.

10. An oral care implement comprising:

a handle;

a head having a proximal end coupled to the handle, a distal end, a longitudinal axis extending from the proximal end to the distal end, and a base structure having a front surface;

a cleaning element carrier having a top surface, a bottom surface, and a peripheral edge extending between the top and bottom surfaces, the cleaning element carrier supported so that an entirety of the bottom surface and the peripheral edge of the cleaning element carrier are spaced from the front surface of the base structure by a gap, at least a portion of the cleaning element carrier movable relative to the base structure in a direction towards the front surface of the base structure;

a plurality of first cleaning elements mounted to the cleaning element carrier and extending from the top surface of the cleaning element carrier; and

a plurality of second cleaning elements mounted to the base structure and extending from the front surface of the base structure and beyond the top surface of the cleaning element carrier.

11. The oral care implement of claim 10, wherein the cleaning element carrier is elongated in the direction of the longitudinal axis.
