Toothbrush

An oral care implement sanitization system that includes an oral care implement and a case for storing the oral care implement and activating a sanitization or sterilization procedure. The oral care implement may include tooth cleaning elements, a light source, and a first electrical coupling element operably coupled to the light source. The case may include a housing having a cavity for holding the oral care implement, a power source, and a second electrical coupling element operably coupled to the power source. When the oral care implement is positioned within the cavity of the housing of the case, the first and second electrical coupling elements are operably coupled together. Operable coupling of the first and second electrical coupling elements initiates, either immediately or upon the occurrence of some additional action, activation of the light source for sanitizing or sterilizing the tooth cleaning elements.

Oral care implement

Refill head for a toothbrush

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 and Z is in a range of 0.04 to 0.065.

A personal care implement includes a treatment device having a longitudinal axis and including a treatment portion having at least one treatment element; a connection portion having a main body and a first resilient snap attachment protruding from the main body, the main body formed of a first material having a first hardness and the first resilient snap attachment formed of a second material having a second hardness, the first hardness being greater than the second hardness; and the treatment device is alterable between: (1) a detached state; and (2) an assembled state in which the treatment device is detachably coupled to a grip section such that the first resilient snap attachment cooperates with and engages a first engagement portion of the grip section to secure the treatment device to the grip section.

Personal care implement with replacement head

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.

Oral care implement, handle thereof, and oral care refill head therefor

An oral care implement having conductive protrusions. In one embodiment, the oral care implement includes a handle and a head coupled to the handle. Furthermore, the oral care implement includes a power source. A plurality of conductive protrusions may be electrically coupled to the power source. The plurality of conductive protrusions may include a base proximate the head and a distal end spaced from the head. Furthermore, at least one of the conductive protrusions may taper from the base to the distal end.

Oral care implement with conductive protrusions

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.

Brush with fluid delivery

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.

A toothbrush handle includes a support structure formed of clarified polypropylene and a body formed of thermoplastic elastomer disposed on the support structure. The support structure includes a web having a thickness in a first direction orthogonal to an axis of the toothbrush handle of less than 2 millimeters and at least one rib depending from the web and having a thickness in a second direction, orthogonal to the axis and angled relative to the first direction, of less than about 2 millimeters. The body at least partially covers the web and the at least one rib. The handle has a light transmissivity of greater than 40% through a portion of the handle at which the body covers the web and the at least one rib.

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.

An toothbrush having a handle and a head. The handle may include a first component and a second component covering at least a portion of the first component. The first and second components may be chemically compatible. The first and second components may both comprise a hard polyolefin. The first and second components may have different transparencies. In one aspect, the first component may be opaque and the second component may be transparent or semi-transparent. In some aspects, the handle may also include a third component comprising a thermoplastic elastomer. Furthermore, there may be at least one projection extending outwardly from an outer surface of the first component.
