摘要： A monofilament bristle (200) is disclosed that comprises coextruded core (210) and sheath components (220). The sheath component (220) has an outer surface (218) and surrounds a first portion (215) of the core component (210). A second portion (216) of the core component (210) protrudes from a top terminal end (203) of the sheath component (220) to form an exposed tip portion (203). In one embodiment, the exposed tip portion (203) of the core component (210) has an outer surface (217) that includes friction-enhancing features. In another embodiment, the exposed tip portion (203) is tapered and has an outer surface (217) with a first roughness and the outer surface (218) of the sheath component (220) has a second roughness, the second roughness being greater than the first roughness In a further embodiment, the core component (210) has an outer surface (217) configured to have higher coefficient of friction than the outer surface (218) of the sheath component (220). In other embodiments, an oral care implement (100) including one or more of the monofilaments described herein is disclosed.

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.

摘要： An oral care implement (100) including a head portion (120) that extends from a proximal end (121) to a distal edge (122) along a longitudinal axis (A-A). The head portion (120) may be formed of a cellulosic material such as a wood material or a bamboo material having a longitudinal grain direction. The head portion (120) may include a plurality of tuft holes (130) such that a bristle tuft (151) is anchored to the head portion (120) within each of the tuft holes (130) by an anchor (200). The anchors (200) may extend along an anchor axis that is oblique to the longitudinal axis (A-A). The bristle tufts (151) may include perimeter bristle tufts (153,154) located within perimeter tuft holes (140) that are adjacent to a perimeter (128) or peripheral edge (126,127) of the head portion (120). The perimeter tuft holes (140) may be located at least 1.80 mm from the perimeter (128) of the head portion (120).

摘要： An oral care product array includes a handle component and multiple refill components therefor. The handle component includes a power source. A first refill component includes a first light generating module which emits light in a first spectrum from the first refill component. A second refill component includes a second light generating module which emits light in a second spectrum from the second refill component. Each refill component has a coupled state, when coupled to the handle component, and a decoupled state, when decoupled from the handle component. When the first refill component is in the coupled state, the first light generating module is powered by the power source to emit light in the first spectrum. When the second refill component is in the coupled state, the second light generating module is powered by the power source to emit light in the second spectrum.

摘要： A light-emitting oral care implement includes a light delivery unit that includes a passageway through a body of the oral care implement and a tuft comprising a plurality of filaments located in the passageway, each of the filaments having a core component and a sheath component. The core component may have a transmittance that is greater than the transmittance of the sheath component. The core component may include a base portion that protrudes from a lower end of the sheath component, the base portion forming an anchor portion of the tuft that anchors the tuft to the body of the oral care implement. Furthermore, the oral care implement may include a light source that transmits lights through the anchor portion of the tuft and through the core components for transmittance from the filaments at a location above a front surface of the body.

摘要： An oral care implement that includes a handle and a head. The head, which has an exposed front surface and an exposed rear surface, may include a support structure having a perimetric wall that defines a central opening and a monolithic cleaning unit including a pad located within the central opening and molded bristles extending from the pad. The support structure and the pad may collectively define the exposed front surface and the exposed rear surface of the head. Furthermore, the support structure may have a maximum thickness of 3 mm or less measured from a front surface of the perimetric wall to a rear surface of the perimetric wall.

摘要： A toothbrush (100) including a head portion (120) formed from bamboo. A plurality of tuft holes (130) are formed into the head portion (120) and a bristle tuft (151) is positioned within each of the tuft holes (130) and secured by an anchor wire (200). The anchor wire (200) may be formed from a metal alloy that includes nickel. The anchor wire (200) includes a plurality of first grooves (210) in its first surface (203) and a plurality of second grooves (220) in its second surface (204). The grooves (210, 220) may have sidewalls (212, 213, 222, 223) that are perpendicular to its floor (211, 221). A width (WG1, WG2) of the grooves (210, 220) may be equal to a spacing (D2, D5) between the grooves (210, 220) and greater than a thickness (Ti) of the anchor wire (200).
