US Patent 7717635 Liquid dispensing brush

A liquid dispensing cleaning or scrubbing device that includes a handle and a scrubbing head. The handle is hollow and holds a cleaning liquid. The head twists from an open position to a closed position. When the head is an open position, the user pushes a button on the back of the head to deliver a substantial amount of cleaning liquid to the bottom of the scrubbing head. The head receives liquid through a re-sealable inset screw cap filler port. The filler port is on the bottom of the head, and when the scrubbing device is fully assembled the filler port is completely and conveniently out of the user's way.
