Oral care implement handle

An oral care implement handle () having a gripping portion () and an oral care refill head () that is detachably coupled thereto. The oral care implement handle () may include the gripping portion () and a rocker unit () which includes a stem (), a motor (), and a motor chassis (). The rocker unit () may be pivotably mounted within the gripping portion () so that upon pressure being applied an oral care refill head () which is coupled to the stem () that exceeds a pressure threshold, the rocker unit () may be altered from a normal position to an excessive pressure position. When in the excessive pressure position, the rocker unit () may actuate an actuator element () of a control unit () to initiate generation of a user perceptible signal.

Oral care implement and handle thereof

Oral care implement

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 ().

Brush head of an 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.
