Abstract
An oral care device having a handle, a neck, and a pair of curved arms. The handle includes an enlarged distal end and a reduced proximal end, and a pair of downwardly-extending handle walls. The handle walls are spaced at their upper ends and converge with and join one another at their lower ends to define a substantially V-shaped cross-section and an upwardly-opening blind cavity. A neck extends distally from the handle and defines a tongue portion that is recessed relative to a top surface. A pair of curved arms extend distally and downwardly from the neck. When substantially identical oral care devices are stacked one upon the other, the upwardly-opening blind cavity of one oral care device nestingly receives the downwardly-extending handle walls of another oral care device.
