Abstract: An oral care implement is described. The oral care implement may include a head extending along a longitudinal axis and having a first surface, a second surface opposite the first surface, and a side surface extending between the first surface and the second surface. A central bristle tuft may from a central portion of the first surface. A plurality of perimetric bristle tufts may from the first surface and arranged to circumferentially surround the central bristle tuft. The perimetric bristle tufts may have distal ends that slope downwardly towards the central bristle tuft. The perimetric bristle tufts may be wedge shaped.

Abstract: An oral care implement having a head and a handle. A plurality of tooth cleaning elements extend from an exposed front surface of the head. The handle has an open thumb gripping passageway extending between an exposed first surface of the handle and an exposed second surface of the handle opposite the exposed first surface. The handle also has a plurality of slots defining open slot passageways from the exposed first surface of the handle to the exposed second surface of the handle. The open thumb gripping passageway may be defined by a ring component that is fitted into an aperture in a body component. The open thumb gripping passageway may be a void space in the handle. The open slot passageways may be elongated along the handle and may serve to reduce a total amount of virgin material needed to manufacture the oral care implement.

Abstract: A toothbrush includes a handle, a head at a distal end of the handle comprising a bristle plate, a hole extending through the bristle plate, a plurality of bristles at least partially disposed in the hole and extending from the hole in a direction away from the head, and a reservoir in fluid communication with the hole. Fluid in the reservoir enters the tuft holes and is wicked out of the head of the toothbrushes by capillaries formed between the bristles.

Abstract: 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.

Abstract: An oral care implement having a head with a bristle bearing surface. The oral care implement may include a central bristle tuft extending from a central portion of the bristle bearing surface, the central bristle tuft terminating in a domed distal surface. Furthermore, the oral care implement may include a plurality of perimetric bristle tufts extending from the bristle bearing surface and arranged to circumferentially surround the central bristle tuft. Each of the perimetric bristle tufts may have an inclined distal surface that slopes downward towards the central bristle tuft. The bristle bearing surface of the head may have a total surface area (TSA), and the toothbrush may include a tooth cleaning element field having X number of tooth cleaning elements that collectively occupy a total cleaning element area (TCEA) such that 1 X × T C E A T S A = Z and Z is in a range of 0.04 to 0.065.

Abstract: An oral care implement that includes a handle and an oral care refill head. The oral care refill head is alterable between a first state in which it is separated from the handle and a second state in which it is coupled to the handle. The oral care refill head has a proximal edge surface that defines an opening into a sleeve cavity. The proximal edge surface is inclined with radial distance from a cavity axis of the sleeve cavity. Similarly, the handle has a gripping portion that terminates at a distal end and a stem that protrudes from the distal end. The annular shoulder that is inclined downwardly and away from a stem to facilitate mating of the oral care refill head to the handle. The oral care refill head may have features for securing the oral care refill head to the stem of the handle.

Abstract: An oral care implement having a handle, a head, and at least one movable cleaning element coupled to the head. The movable cleaning element may be used as an interdental cleaner. The movable cleaning element may be positioned within a loop formed by fixed cleaning elements on the head. The movable cleaning element may be coupled to an actuator that moves the movable cleaning element between a first position wherein a distal tip of the movable cleaning element is spaced a first distance from a front surface of the head and a second position wherein the distal tip of the movable cleaning element is spaced a second distance from the front surface of the head, the second distance being greater than the first distance. The movable cleaning element may maintain the first and second positions until subsequent actuation of the actuator.

Abstract: An oral care implement having movable and fixed tooth cleaning elements. The oral care implement may include a handle and a head coupled to the handle. The head may include a base that is coupled to the handle and a resilient bridge coupled to the base. The resilient bridge may be flexible between a normal state in which a portion of the resilient bridge is spaced from the base by a gap and a flexed state in which a portion of the resilient bridge is moved toward the base. Tooth cleaning elements may be coupled to the resilient bridge. Furthermore, the resilient bridge may include one or more apertures through which tooth cleaning elements that are fixed to the base may extend.
