A brush head (10) and a method (200) for manufacturing a brush head. The method (200) includes stamping (220) a plurality of openings (62) into a strip or roll of backing material (60). A bristle tuft (21) is inserted into each of the openings in the backing material. A proximal end (23) of each bristle tuft is bonded to a proximal side (63) of the backing material to create a merged proximal end head portion (26). Excess portions of the backing material are removed to form a plurality of carrier elements (24) about the openings from the backing material. The carrier elements form a plurality of merged tuft assemblies (20). A platen (42) of a neck (40) is positioned in relation to the merged tuft assemblies. A matrix material (30) is injected around the platen and the merged tuft assemblies to at least partially encompass the platen and the carrier elements of the merged tuft assemblies.

Method for Manufacturing a Brush

A method for manufacturing a toothbrush having a bristle carrier made of a thermoplastic material with a front side and a rear side is provided. At least one recess formed as a blind hole in the bristle carrier extends from the front side in the bristle carrier, and holds at least one bristle. The at least one bristle is received in a receiving opening of a tool melted to form a thickening at its attachment-side end and inserted with its attachment-side end into the recess. The thermoplastic material is heated and, by pressing the tool against the front side of the bristle carrier, is deformed such that the thermoplastic material is displaced radially inwards into the recess, at least in the region of an edge surrounding the recess, for the form-fitting sealing of the thickening, in that a projection provided radially adjacent to the recess is pressed into the thermoplastic material.
