Abstract: A rotary shaving head 3 has at least one cutter unit 10, each cutter unit comprising a cap 16 having an external surface 20 with hair-entry openings 18 for engaging the skin of a user; and a rotary cutter 24 having cutting elements 32 supported by a carrier 26, the rotary cutter being locatable within and rotatable with respect to the cap. The shaving head further comprises: a support member 12 for supporting the cutter unit; and a retainer 30, arranged to engage and lock with the support member by relative rotation therewith and retain the cap and the rotary cutter therebetween, wherein the retainer comprises an annular body 36, 38 defining a drive opening 42, the annular body being provided with one or more holes 40 allowing cut hairs to pass through. The holes are shaped as directional indicators indicating a direction of rotation of the retainer with respect to the support.

Abstract: The mouthpiece appliance includes an assembly for receiving teeth (12) which includes a plurality of cleansing portions, typically two opposing side portions (14, 16) and an intermediate center portion (18). The brushing portions include bristle sections which are adapted to clean teeth. The appliance includes at least one DC motor assembly (26) with an output shaft with an eccentric mass of crankshaft (28). The appliance further includes a mechanical motor cover comprising a plurality of arm members which are arranged to connect the DC motor assembly to the cleansing portions of the appliance so that as the unbalanced weight on the output shaft rotates, movement of the cleansing portions, toward and away from the teeth or along the surfaces of the teeth occurs, producing cleansing of the teeth.

Abstract: The mouthpiece carrier assembly (12) is adapted and configured to receive the upper and lower teeth of the user. The mouthpiece carrier assembly is driven such that the bristles mounted on the teeth-facing surfaces of the mouthpiece assembly contact said surfaces and provide a cleaning effect therefor. A plurality of bristle sections (30, 32, 34, 41, 44) are secured to the teeth-facing portions of the mouthpiece assembly, wherein the bristle sections each have bristles which have a particular configuration and are otherwise adapted to provide effective cleaning for an associated dental region.

Abstract: The mouthpiece includes a mouthpiece carrier member (14) having upper and lower sections which are adapted to receive the upper and lower teeth of a user. The mouthpiece carrier member has several embodiments which include side members and an intermediate member or members connecting the two side members to define the two sections. A bristle field (20) is mounted on the mouthpiece carrier member for contact with the surfaces of the teeth. The mouthpiece carrier member is moved in such a manner to produce a bristle action which has a significant axial component, resulting in the bristle tufts moving toward the teeth, contacting the teeth and moving away from the teeth, producing cleaning action on the teeth.
