An oral-care implement comprises a mounting surface having a longitudinal axis and a transverse axis perpendicular to the longitudinal axis and a plurality of filaments outwardly extending from the mounting surface in at least one direction not parallel to either one of the longitudinal axis and the transverse axis, each filament having a free end terminating with a tip. At least some of the filaments possess at least one functional characteristic selected from the group consisting of filament's structure, composition, cross-sectional shape, tip geometry, and any combination thereof. A plurality of filament tips comprises a working surface that includes at least a first color and a second color different from the first color. The at least first color forms at least one scaled-up image graphically replicating the at least one functional characteristic, thereby visually communicating to a consumer that the oral-care implement includes filaments having certain functional characteristic(s)&#x2014;and that the oral-care implement possesses superior efficacy attributable to said filaments.

Oral-care implement having color-communicative element

An oral-care implement including a filament comprising an external material and at least a first internal material. The filament includes an elongated flexible body having a length, a longitudinal axis, and a longitudinal outer surface comprising the external material, the elongated body terminating with a tip having a tip surface comprising the external material, wherein the tip surface has therein a plurality of craters distributed throughout the tip surface in a predetermined pattern, each of the craters having a surface edge of a predetermined size and a predetermined shape, walls extending longitudinally from the surface edge and comprising the external material, and a bottom comprising the at least first internal material and situated at a depth from the surface edge, the surface edge being formed by the walls and the tip surface.

Filament having unique tip and surface characteristics

A filament for use in a brush implement comprises an external material and at least a first internal material. The filament includes an elongated flexible body having a length, a longitudinal axis, and a longitudinal outer surface comprising the external material, the elongated body terminating with a tip having a tip surface comprising the external material, wherein the tip surface has therein a plurality of craters distributed throughout the tip surface in a predetermined pattern, each of the craters having a surface edge of a predetermined size and a predetermined shape, walls extending longitudinally from the surface edge and comprising the external material, and a bottom comprising the at least first internal material and situated at a depth from the surface edge, the surface edge being formed by the walls and the tip surface.

Method for producing a toothbrush handle having an inner cavity

A personal care article, such as a toothbrush having an inner cavity made in one molding process.

Toothbrush having an inner cavity

Methods of producing a unitary personal care article such as a toothbrush having an inner cavity.

A process for making a filament for use in a brush implement comprises providing a composite filament comprising an external material and at least one internal material, wherein the tip surface comprises the internal material surrounded by the external material, the internal material having longitudinal shrinkage characteristics that differ from those of the external material; and causing the internal material to shrink inside the external material, whereby the internal material comprising the tip surface sinks relative to the external material comprising the tip surface so that at least one crater is formed at the tip surface of the filament, the at least one crater comprising a bottom formed by the internal material and walls formed by the external material, the at least one crater having a surface edge of a predetermined size and a predetermined shape.
