Abstract:
An enhanced cleaning toothbrush comprising:(a) an elongated handle (12); (b) an elongated head (14) connected to and extending from the handle (12), the head (14) ending in a toe (22) distal from the handle (12); (c) the elongated head (14) having a face (20) on one side thereof and a longitudinal axis therethrough; (d) a plurality of flexible bristle tufts extending from the face (20); (e) the bristle tufts being grouped into a more densely packed first grouping (16) of bristle tufts located proximate to the toe (22) and a less densely packed second grouping (18) adjacent to the first grouping (16) and extending across the balance of the face (20) to the handle (12); (f) each of the first and second bristle tuft groupings (16, 18) have a trim pattern with at least one radius of curvature therein; (g) the bristle tufts within the first grouping (16) being acutely angled (&agr;) with respect to the face (20) toward the toe (22); and (h) the second bristle grouping (18) having a first and second subset of bristle tufts therein, the first subset including the peripheral bristle tufts adjacent to each side of the elongated head (14) and the row of bristle tufts most proximate to the handle (12), which first subset of bristle tufts are acutely angled (&bgr;) with respect to the face (20) toward the toe (22), the second subset of bristle tufts including the balance of bristle tufts in the second grouping (18), are acutely angled (&phgr;) with respect to the face (20) toward the handle (12).
