Abstract
A brush head, particularly a toothbrush head, may have a plurality of cleaning elements, in particular bristle tufts, which are anchored by an end section in a brush carrier, wherein the cleaning elements may be cast with positive engagement in blind-hole shaped retaining recesses. For producing such a brush head different cleaning elements may be placed successively or simultaneously in different mold cavities and may be over-molded using different plastic materials from which injection-molding sections of the bristle carrier are formed in the process. In doing so, a first cleaning element is over-molded in a first mold cavity using a first plastic material, while a second cleaning element is over-molded in a second mold cavity using a second plastic material.
