Abstract

See full text

A head for an oral care implement has a mounting surface and at least one twisted tuft including a plurality of filaments and having a base mounted on the mounting surface. The twisted tuft has an outer lateral surface, a longitudinal axis, a lower cross-sectional area extending in a plane that is perpendicular to the longitudinal axis and that is arranged at the base, and an upper cross-sectional area extending in a plane that is perpendicular to the longitudinal axis and that is arranged at the twisted tuft's free end. The lower cross-sectional area and the upper cross-sectional area have substantially the same shape and size. The filaments forming the outer lateral surface are substantially straight and inclined with respect to the longitudinal axis in either a clockwise direction or in a counterclockwise direction. The upper cross-sectional area is twisted relative to the lower cross-sectional area. The upper cross-sectional area is not congruent with the lower cross-sectional area when they are orthogonally projected onto each other along the longitudinal axis.
