Oral care implement

1. An oral care implement comprising:

a handle;

a head extending from the handle, the head having a face;

a tuft hole in the face, the tuft hole defined by a wall and having a polygonal shaped transverse cross-sectional profile;

a bristle tuft comprising a plurality of bristles mounted in the tuft hole and extending from the face of the head, the bristle tuft comprising a polygonal shaped transverse cross-sectional profile having a perimeter;

wherein each of the plurality of bristles has a polygonal shaped transverse cross-sectional profile that corresponds to the polygonal shaped transverse cross-sectional profile of the tuft hole, the polygonal shaped transverse cross-sectional profile of the tuft hole, the bristle tuft, and each of the plurality of bristles being shaped as a diamond having major axes longer than minor axes; and

wherein an entirety of the perimeter of the bristle tuft is abutted against the wall of the tuft hole.

2. The oral care implement according to claim 1 wherein the packing factor of the tuft hole is greater than 90%.

3. The oral care implement according to claim 2 wherein the packing factor of the tuft hole is approximately 100%.

4. The oral care implement according to claim 1 wherein the plurality of bristles are formed of polybutylene terephthalate, polyethylene terephthalate, or nylon.

5. An oral care implement comprising:

a handle;

a head extending from the handle, the head having a face;

a first tuft hole in the face, the first tuft hole having a longitudinal axis and a transverse cross-sectional profile comprising a minor axis and a major axis, the major axis of the first tuft hole being longer than the minor axis of the first tuft hole;

a first bristle tuft mounted in the first tuft hole and extending from the face of the head, the first bristle tuft comprising a first plurality of bristles;

wherein each of the first plurality of bristles comprises a longitudinal axis and a transverse cross-sectional profile having a minor axis and a major axis, the major axes of the first plurality of bristles being longer than the minor axes of the first plurality of bristles;

wherein the major axes of the first plurality of bristles extend between first pairs of opposing apexes of the transverse cross-sectional profiles of the first plurality of bristles and the minor axes of the first plurality of bristles extend between second pairs of opposing apexes of the transverse cross-sectional profiles of the first plurality of bristles; and

wherein the major axes of the first plurality of bristles are substantially parallel to the major axis of the first tuft hole; and

a second tuft hole in the face, the second tuft hole having a longitudinal axis and a transverse cross-sectional profile comprising a minor axis and a major axis, the major axis of the second tuft hole being longer than the minor axis of the second tuft hole;

a second bristle tuft mounted in the second tuft hole and extending from the face of the head, the second bristle tuft comprising a second plurality of bristles; and

wherein the major axis of the first tuft hole is non-parallel to the major axis of the second tuft hole.

6. The oral care implement according to claim 5 wherein adjacent bristles of the first plurality of bristles are positioned within the first tuft hole so that their edges are aligned and abutted against each other.

7. The oral care implement according to claim 5 wherein each bristle of the first plurality of bristles has at least two edges that are abutted against an edge of an adjacent bristle and wherein remaining edges of each bristle are abutted against a wall bounding the first tuft hole.

8. The oral care implement of claim 5 wherein the major axis of the first tuft hole is substantially perpendicular to the major axis of the second tuft hole.

9. The oral care implement of claim 8 wherein each of the second plurality of bristles comprises a longitudinal axis and a transverse cross-sectional profile having a minor axis and a major axis, the major axes of the second plurality of bristles being longer than the minor axes of the second plurality of bristles, wherein the major axes of the second plurality of bristles are substantially parallel to the major axis of the second tuft hole.
