  • Publication number: 20210161282
    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.
