  • Patent number: 12004922
    Abstract: A dog toothbrush assembly has two plastic end caps with blind cavities that face one another and receive an elongated generally cylindrical chew element which is attractive to dogs such as an edible treat or other chewable material. The end caps are connected by screw fasteners to the support member of a brush, and an array of tufts of bristles project upwardly from the support member to engage the elongated chew element. The chew element is supported with respect to the bristles such that when a dog chews on the chew element the dog's teeth also encounter and are brushed by the bristles. When the chew element is worn or consumed, an end cap is removed by releasing one of the screw fasteners, thereby giving access for insertion of a replacement chew element.

  • Patent number: 11576481
    Abstract: A head for an oral-care implement, having an elongated mounting surface with an outer circumference, includes two outer rows of tufts extending from the mounting surface along the longitudinal axis in proximity to the outer circumference, and two inner rows of tufts extending from the mounting surface and arranged between and parallel to the outer rows. The tufts of the outer rows have a longitudinal extension and an elongated cross-sectional area perpendicular thereto. The elongated cross-sectional area has a longer axis and a shorter axis, wherein the longer axis defines an angle ? of about 20-65 degrees relative to the longitudinal axis. The tufts of the outer rows are inclined relative to the mounting surface by an inclination angle (?) of about 65-80 degrees. The tufts of the inner rows are inclined relative to the mounting surface by an inclination angle (?) of about 60-85 degrees.

  • Patent number: 11457725
    Abstract: 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.

  • Patent number: 11445810
    Abstract: A mechanically tapered bristle filament for an oral care implement. The filament is characterized by a long thin tapered end portion. The tapered end portion has a taper length and tip diameter comparable to chemically tapered filaments. The areal surface roughness of the tapered end portion however is greater than chemically tapered filaments thereby producing increased scrubbing action against the surfaces of the teeth. The foregoing taper and roughness characteristics of the present filament enhance inter-dental cleaning effectiveness.
