    Abstract: A monofilament bristle (211) including: a body portion (215); a tip portion (217) extending from the body portion (215) and comprising a multi-lobed transverse cross-section (221), the monofilament bristle (211) extending along a longitudinal axis (219); co-extruded first and second components, the first component being a first color and forming a first lobe (223a) of the multi-lobed transverse cross-section (221), the second component being a second color, which is different from the first color, and forming a second lobe (223b) of the multi-lobed transverse cross-section (221); and each of the first and second components forming a longitudinal section of the body portion (215), with an interface between the first and second components extending substantially parallel to the longitudinal axis (219).

    Abstract: 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.

    Abstract: 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.
