Abstract
A toothbrush comprising a tapered bristle having a cross-sectional profile with a major axis and a minor axis. In one embodiment, the invention can be an oral care implement comprising: a head; a handle; and at least one tapered bristle extending from a face of the head, the tapered bristle having a longitudinal axis and a transverse cross-sectional profile having a major axis and a minor axis, the major axis being longer than the minor axis.
Claims20
An oral care implement comprising:
- a head having a face with a tuft hole therein;
- a handle coupled to the head;
- a plurality of tapered bristles disposed within the tuft hole and arranged in a bristle tuft that extends from the face of the head, the bristle tuft comprising a first subset of the tapered bristles and a second subset of the tapered bristles;
- wherein each of the tapered bristles comprises a longitudinal axis and a transverse cross-sectional profile having a major axis and a minor axis, the major axes of the tapered bristles being longer than the minor axes of the tapered bristles;
- wherein the major axes of the tapered bristles of the first subset are non-parallel to the major axes of the tapered bristles of the second subset;
- and
- wherein the first and second subsets of the tapered bristles are arranged in an alternating configuration of columns or rows.
