    Abstract: An oral care implement used for treatment of a user's oral cavity. The oral care implement may include a body having a longitudinal axis, a first hard plastic component, and a second hard plastic component. The first hard plastic component may have a front surface having a perimeter portion and a central portion that is surrounded by the perimeter portion, the central portion being recessed relative to the perimeter portion. The second hard plastic component may be positioned on the central portion of the first hard plastic component and surrounded by the perimeter portion of the first hard plastic component. The second hard plastic component may have an outer surface with a plurality of grooves that are elongated in a direction of the longitudinal axis.

    Abstract: An toothbrush having a handle and a head. The handle may include a first component and a second component covering at least a portion of the first component. The first and second components may be chemically compatible. The first and second components may both comprise a hard polyolefin. The first and second components may have different transparencies. In one aspect, the first component may be opaque and the second component may be transparent or semi-transparent. In some aspects, the handle may also include a third component comprising a thermoplastic elastomer. Furthermore, there may be at least one projection extending outwardly from an outer surface of the first component.

    Abstract: An oral care implement that includes a handle and a head. A tuft of cleaning elements extends from the front surface of the head along an axis and includes a plurality of cleaning elements. In one embodiment, the cleaning elements may be formed of an elastomeric material. Furthermore, a sleeve may be coupled to the head and extend from the front surface of the head. The sleeve circumferentially surrounds a first portion of the tuft of cleaning elements and a second portion of the tuft of cleaning elements protrudes beyond a distal end of the sleeve. The sleeve may apply a radial compression force onto the first portions of the cleaning elements that are surrounded by the sleeves. The second portions of the cleaning elements may diverge as they extend from the distal end of the sleeve. The oral care implement may include sleeves of varying heights.
