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

Oral care implement

Toothbrush

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.

Oral irrigator

A spiral bristle () includes: a first component (), a second component (), and a third component (), with each of the second and third components () wrapping around the first component () in a helical and spaced-apart manner, the second and third components () isolated from one another by the first component (). An oral care implement includes the spiral bristle.

Oral care implement and spiral bristle for use with the same

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

Oral care implement and monofilament bristle for use with the same

An oral care implement () includes an elastomeric component and a method of forming the same. In one embodiment, the oral care implement () includes a handle () and a head (). The elastomeric component is positioned on at least one of the handle () and the head (). The elastomeric component includes a body, a plurality of the first particles (), and a plurality of the second particles (). 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 () includes a first color and the plurality of second particles () includes a second color. The elastomeric component may form a tissue cleanser () on a rear surface of the head, an elastomeric tooth cleaning element () on a front surface of the head, and/or a grip () on the handle ().

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

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.

Light emitting oral care implement

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.

Light-emitting oral care implement and method of forming the same

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