Abstract: A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.

Abstract: Described herein is an oral care implement that includes a head portion; a cup member extending from a front surface of the head portion along a first axis, the elastomeric cup member comprising: a top surface; a plurality of grooves formed into the top surface; a plurality of rib members, wherein adjacent ones of the grooves are separated by one of the rib members, each of the rib members extending along a rib axis that extends radially outward from the first axis, and wherein each of the rib members has a thickness that increases with distance from the first axis. The cup member may comprise a plurality of first grooves and a plurality of second grooves, and wherein each of the first grooves has a first transverse cross-section and each of the second grooves has a second transverse cross-section, the first and second transverse cross-sections being different from one another.

Abstract: A powered toothbrush head that, in one embodiment, includes a head portion including a first movable tuft block configured for holding tooth cleaning elements. The first movable tuft block is operably connected to a motor-driven drift shaft for movement. An eccentric cam formed on the shaft drives the first movable tuft block via engagement with a slot formed in the body of the first movable tuft block. The first movable tuft block is movable in a combination oscillating motion comprising vertical motion and lateral pivoting or tilting motion upon rotation of the drive shaft. A related method for oscillating the first movable tuft block is disclosed.

Abstract: A powered toothbrush apparatus with capacitive touch control, which includes a head portion having an oscillating tuft block driven by a motor, a handle portion, and an elastically deformable capacitive touch control panel mounted in the handle portion. In one embodiment, the control panel includes movable sensor targets each paired with a corresponding capacitance sensor electrically connected to a programmable microprocessor. Applying finger pressure on the control panel adjacent a sensor target operates to change the capacitance of the respective sensor target-sensor pair. The microprocessor detects the change in capacitance, which may be used to control the motor speed for changing the oscillation rate of the tuft block. In one embodiment, a linear array of sensor targets-sensors is provided which is activated by a sliding finger or thumb motion across the array. A related operating method is disclosed.
