A head for an oral care implement has a mounting surface and at least one tuft mounted thereon. The tuft has a longitudinal axis and a cross-sectional area extending in a plane perpendicular to the longitudinal axis. The tuft comprises a plurality of substantially cylindrical filaments. Each filament has a longitudinal axis and a cross-sectional area extending in a plane that is perpendicular to the longitudinal axis. The cross-sectional area of an individual filament has a substantially non-circular shape. The plurality of filaments is arranged such that the cross-sectional area of the tuft has a scaled-up shape of the individual filament's cross-sectional area.

Head for an oral care implement

A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels. The projections and channels are arranged in an alternating manner. Each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius, and each projection is end-rounded thereby forming a curvature. The curvature has a diameter, and the ratio of the diameter of the curvature of the projection to the radius of the curvature of the channel is from about 0.2 to about 1.5.

Filament for an oral care implement and oral care implement

A filament for an oral care implement has a longitudinal axis and a substantially cross-shaped cross-sectional area extending in a plane substantially perpendicular to the longitudinal axis. The cross-shaped cross-sectional area has four projections and four channels, the projections and channels are arranged in an alternating manner. The cross-sectional area has an outer diameter, and each channel has a concave curvature formed by neighboring and converging projections. The concave curvature has a radius which is within a range from about 0.015 mm to about 0.12 mm, and the ratio of the outer diameter to the radius is within a range from about 2.5 to about 12.

A brush implement for the use with a skin treatment device, the brush implement having bristles of a first type and bristles of a second type, wherein the bristles of the first type are longer than the bristles of the second type and are positioned closer to the outer contour of the brush implement and the bristles form at least three distinguishable sectors.

An oral cleaning implement can be produced by stapling at least one bristle filament and/or one or more bristle tufts into a tuft hole. Staples used for said stapling may be produced from plastic material by extrusion technology. Said staples may have a cavity formed along one of its axis and optional one or more recesses at its side faces.

A method for producing a brush head for a toothbrush head is disclosed. The method includes the steps of providing a bristle carrier; providing cleaning elements having first ends which will not be embedded in the bristle carrier and second ends which will be embedded in the bristle carrier, wherein the cleaning elements are selected from at least two different types of cleaning elements or at least two distinctive cleaning elements of the same type; placing the first ends of the cleaning elements in the bristle carrier in a carrier part for holding; and supplying different amounts of heat to the second ends in the bristle carrier by reflecting the heat supplied partially from the carrier part and/or absorbing the heat supplied partially by the carrier part resulting in the second end being molten.
