BRUSH HEAD ASSEMBLY AND METHODS OF MANUFACTURE

摘要

A brush head assembly (100) including: a hard platen (24); a plurality of bristle tufts (21), each of which includes a plurality of bristle strands having a proximal end (23) and a free end (25); and an elastomeric matrix (30) bonded to the hard platen, where each of the bristle tufts is bonded directly to the elastomeric matrix without a retention element. A brush head assembly (100) includes: a hard platen (24) with a plurality of bristle tuft holes (28); a plurality of bristle tufts (21), each of which includes a plurality of bristle strands having a proximal end (23) and a free end (25), where each of the plurality of bristle tufts are inserted into a respective one of the bristle tuft holes; and an elastomeric matrix (30) that at least partially encompasses the hard platen and the proximal end of the bristle tufts.
