Abstract
A brushing component is provided. The brushing component comprises an inner group of angled bristle tufts arranged with rotational symmetry about a point of symmetry. The brushing component also comprises a set of outer groups of angled bristle tufts surrounding the inner group and having rotational symmetry with respect to a second point of symmetry. The first and second points of symmetry are both positioned on a longitudinal axis of the support surface. The proposed component provides improved brushing performance to an increased proportion of the user's oral surface over conventional brushing components.

A brushing component for an oral hygiene product, wherein the brushing component comprises:
- a support surface;
- a first inner group of bristle tufts extending from the support surface and comprising a plurality of angled bristle tufts arranged to have rotational symmetry with respect to a first point of symmetry;
- a second inner group of bristle tufts extending from the support surface, wherein the second inner group of bristle tufts comprises a second plurality of angled bristle tufts arranged to have rotational symmetry with respect to a second point of symmetry;
- and,
- a set of outer groups of bristle tufts extending from the support surface, each outer group of bristle tufts comprising one or more angled bristle tufts,
- wherein the set of outer groups of bristle tufts is arranged to surround the first and second inner groups of bristle tufts and further arranged to have rotational symmetry with respect to a third point of symmetry,
- wherein the first and second inner groups are arranged in a linear array and spaced apart from one another,
- and wherein the first point symmetry, the second point of symmetry, and the third point of symmetry are all positioned on a longitudinal axis of the support surface.
