The middle ring includes at least two middle bristle tufts that each have a cross-section that is smaller than the cross-section of the outer bristle tufts and a central area including at least one bristled section that consists of two center bristle tufts having a cross-section larger than the cross-section of the middle bristle tufts.

Abstract: The invention is directed to a bristle for a toothbrush, said bristle being comprised of a plastic monofilament, with the preferably cloverleaf-shaped bristle body having several longitudinal ribs arranged in star shape and projecting laterally from a core section of the bristle body. The invention is also directed to a brush head for an electric toothbrush having at least one bristle tuft with at least one such bristle as well as to an electric toothbrush having such a brush head. According to the invention, the bristle of the type initially referred to is configured to be self-fanning in such a manner that the cleaning forces acting on the bristles during normal brushing cause the bristle to split open at its free end. As a result, the need to use complex splitting methods and corresponding splitting machines in the manufacture of the toothbrush can be obviated.

Abstract: A cleaning section for an electric oral hygiene device having a handle section includes a first end adapted to be connected to the handle section; a second end remote from the first end, the second end including a carrier mounted for rotation or oscillation around a rotation axis; and a plurality of cleaning elements mounted on the carrier, the cleaning elements being arranged in at least an inner band and an outer band. The inner band includes a plurality of first cleaning elements having a first color and a plurality of second cleaning elements having a second color. The outer band includes a plurality of third cleaning elements having a third color and a plurality of fourth cleaning elements having a fourth color. The cleaning elements of the inner band and the cleaning elements of the outer band have a Color Contrast (?E) of from about 85 to about 140.

Abstract: A toothbrush is disclosed. The toothbrush includes a head; a base member supported by a neck; a support member having a plurality of holes therein; a resilient cushion member disposed, at least in part, between the base member and the support member, the cushion member being fixed to the support member; at least one center bristle tuft extending from the support member; and two or more outer bristle tufts located at least partially around the at least one center bristle tuft. The center bristle tuft has a first shaped cross section and the outer bristle tufts have a second shaped cross section. The first shaped cross section is different from the second shaped cross section. Applying a force to the center bristle tuft and/or the outer bristle tufts causes the center bristle tuft and/or the outer bristle tufts to deflect into the resilient cushion member.

Abstract: A head for an electric toothbrush includes a support member having a plurality of holes extending completely therethrough. A plurality of tufts of bristles each extends through one of the holes. A first brushing end of each tuft projects from a first side of the support member. Each tuft is prevented from being withdrawn from its hole when a tensile force is applied to the first end of each tuft along a long axis of the tuft. A resilient cushion is positioned adjacent a second side of the support member such that a second end of each tuft can contact the cushion. When a compressive force is applied to the first end of each tuft along the long axis of each tuft, each tuft can move in its hole in a first direction into the cushion. When the compressive force is removed the cushion causes each tuft to move in its hole in a second direction substantially opposite the first direction.
