BRUSH HEAD ARRANGEMENTS

摘要

A brush head (100), including: an elastomeric matrix (30) including a first surface (32); a plurality of retention rings (50) disposed in the elastomeric matrix, each of which includes a first end (51), a second end (53) positioned closer to the first surface of the elastomeric matrix than the first end, an interior wall (55) forming an interior space (59) with a central longitudinal axis (111), and an exterior wall (57). At least one of the interior wall and the exterior wall of at least a first retention ring of the plurality of retention rings (50) includes a taper (61, 67, 73, 63, 69, 71). A plurality of bristle tufts (21), each of which comprises a plurality of bristle strands, having a proximal end (23) and a free end (25), is retained at its proximal end within the interior space of one of the plurality of retention rings.
