  • Patent number: 11160358
    Abstract: A personal care implement includes a treatment device having a longitudinal axis and including a treatment portion having at least one treatment element; a connection portion having a main body and a first resilient snap attachment protruding from the main body, the main body formed of a first material having a first hardness and the first resilient snap attachment formed of a second material having a second hardness, the first hardness being greater than the second hardness; and the treatment device is alterable between: (1) a detached state; and (2) an assembled state in which the treatment device is detachably coupled to a grip section such that the first resilient snap attachment cooperates with and engages a first engagement portion of the grip section to secure the treatment device to the grip section.

  • Patent number: 10987204
    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.

  • Patent number: 10952529
    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.
