    Abstract: Oral care implement that can be detachably coupled to a handle having a motor. The oral care implement includes a drive assembly to operably engage the motor, a head portion that includes a body, a first carrier comprising a plurality of bristle tufts extending from the first carrier, the first carrier comprising a central passageway; and a second carrier disposed within the central passageway of the first carrier, the second carrier comprising an elastomeric cleaning element extending from the second carrier. The drive assembly may be operably coupled to each of the first and second carriers and configured to: (1) produce a first oscillatory motion of the first carrier about a first rotational axis; and (2) produce a second oscillatory motion of the second carrier, the second oscillatory motion being counter to the first oscillatory motion.

    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.
