Abstract

The present invention is directed to a brush head, particularly a toothbrush head, and to a method of manufacturing such a brush head. The brush head includes a bristle carrier and bristles fixedly secured thereto, said bristle carrier having a slot-type recess in which a multiplicity of bristles is received forming an elongated tuft with a closed, smooth outer contour corresponding essentially to the contour of the slot-type recess. According to the invention the brush head is characterized in that the slot-type recess is divided by means of at least one transverse wall into several segments, a separate tuft is inserted and secured in each of the segments, and the at least one transverse wall is constructed so that the separate tufts converge, forming in combination the elongated tuft with a closed, smooth outer contour.
