发明名称 Toothbrush head
摘要 The invention is directed to a brush head, in particular a toothbrush head, having a bristle carrier and bristles attached thereto, which are seated in the form of tufts in holes in the bristle carrier and fastened by their ends close to the bristle carrier to the bristle carrier without anchoring, in particular by welding and/or adhesive bonding to a rear side of the bristle carrier using the method referred to as anchor-free tufting. According to the invention, at least one hole (2) in the bristle carrier (1) is divided by means of at least one transverse wall (4) into several segments and said at least one transverse wall is constructed such that the bristles seated in the segments form a common tuft (3) with a smooth and closed outer contour corresponding to the contour of the hole and are supported by the transverse wall.
