摘要: 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.

摘要: An oral care implement (100) includes an elastomeric component and a method of forming the same. In one embodiment, the oral care implement (100) includes a handle (120) and a head (110). The elastomeric component is positioned on at least one of the handle (120) and the head (110). The elasto-meric component includes a body, a plurality of the first particles (202), and a plurality of the second particles (203). The body comprises a transparent or translucent elastomeric material. The pluralities of first and second particles are embedded in the body of the elastomeric component. The plurality of first particles (202) includes a first color and the plurality of second particles (203) includes a second color. The elastomeric component may form a tissue cleanser (140) on a rear surface of the head, an elastomeric tooth cleaning element (150) on a front surface of the head, and/or a grip (121) on the handle (120).

摘要: 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.

摘要: A toothbrush handle includes a support structure formed of clarified polypropylene and a body formed of thermoplastic elastomer disposed on the support structure. The support structure includes a web having a thickness in a first direction orthogonal to an axis of the toothbrush handle of less than 2 millimeters and at least one rib depending from the web and having a thickness in a second direction, orthogonal to the axis and angled relative to the first direction, of less than about 2 millimeters. The body at least partially covers the web and the at least one rib. The handle has a light transmissivity of greater than 40% through a portion of the handle at which the body covers the web and the at least one rib.
