US Patent 10285567 Dish scrubber with changeable scrub head

A dish scrubbing brush includes an elongated handle and a brush head adapted to be releasably attached to the top of the handle. A hollow reservoir located within the handle contains liquid soap. An orifice at the top of the handle communicates with the brush head when it is attached and a pump accessible from the exterior of the handle forces soap from the reservoir to the brush head. The brush head includes a foam brush and an adapter for securing the brush head to the top of the handle. The adapter includes an internal thread that cooperates with a partial external thread on the handle top and includes a rib that cooperates with a slot in the handle top. As the adapter is rotated to be attached to the handle, the brush is drawn toward the handle but does not rotate relative thereto.
