<p>In a toothbrush (1) comprising a grip member (2) and a brush member (36) connected to the grip member (2), which brush member has a longitudinal axis (39) and carries a bristle holder (40) which is mounted on the brush member (36) so as to be movable with respect to a holder axis (41) and which has a holder surface (69) which extends substantially transversely to the holder axis (41) and from which, in the area of the holder surface (69), bristles (70) project transversely to the holder surface (69) and together form a bristle field (71), the free ends of at least a part of the bristles (70) of the bristle field (71) arranged around the holder axis (41) are bounded by two non-stepped enveloping surfaces (72, 73) which are inclined continuously with respect to the bristle holder (40), which enveloping surfaces are arranged substantially in a V-shape relative to the holder surface (69) of the bristle holder (40) and intersect one another along a line of intersection (74) at the location of the holder axis (41), the line of intersection (74) of the two enveloping surfaces (72, 73) extending transversely to the longitudinal axis (39) of the brush member (36).</p> |
