Oral care implement

摘要

An oral care implement that rotates about a longitudinal axis. In one aspect, the invention can be an oral care implement comprising: a head; a handle extending along a longitudinal axis and having a flat base surface; a mechanical vibratory device operatively connected to a power source, the mechanical vibratory device comprising an eccentric imparting movement to the head when activated; and wherein the flat base surface is oriented relative to the longitudinal axis of the handle so that the oral care implement can stand in a self-supporting upright orientation on a horizontal flat surface, and wherein when the oral care implement stands in the self-supporting upright orientation and the mechanical vibratory device is activated, the oral care implement rotates about the longitudinal axis while maintaining the self-supporting upright orientation.

1. An oral care implement comprising:
a head comprising a front surface; a plurality of bristles extending from the front surface of the head, the front surface of the head disposed within a reference plane; a handle extending along a longitudinal axis, a proximal end of the handle comprising a flat base surface; a mechanical vibratory device operatively connected to an electric power source, the mechanical vibratory device comprising an eccentric rotatable about a rotational axis to impart vibration to the head when the mechanical vibratory device is activated; wherein the head is offset from the longitudinal axis of the handle and extends along an axis that is parallel to the longitudinal axis of the handle; wherein the flat base surface is oriented relative to the longitudinal axis of the handle so that the oral care implement can stand in a self-supporting upright orientation on a substantially horizontal flat surface, wherein when the oral care implement stands in the self-supporting upright orientation and the mechanical vibratory device is activated, the oral care implement rotates about the longitudinal axis while maintaining the self-supporting upright orientation; and wherein the rotational axis is inclined relative to the reference plane so that the eccentric diverges from the reference plane with increased distance from the proximal end of the handle.
