ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of cleaning implements and more particularly, to mops. The field of the present invention more particularly relates to the field of mops having a self contained reservoir of cleaning liquid and means for causing the liquid to be dispensed from the reservoir in measured amounts so that the cleaning liquid is sprayed ahead of the mop to facilitate cleaning.

20. U.S. Pat. No. 6,227,744 B1 issued to Fodrocy on May 8, 2001 for “Liquid Dispensing Apparatus For Cleaning Implements” (hereafter the “Fodrocy Patent”);
21. PCT Application No. PCT/FR86/00087 filed on Sep. 25, 1986 for “Apparatus Combining Chemical And mechanical Action, To Remove Residues Adhering To The Soil; Also Use Of the Apparatus For Sweeping And Spreading Liquid Products” (hereafter the “'00087 PCT Application”);
The Cushing Patent discloses a mop assembly provided to uniformly and controllably apply and distribute liquids to the surfaces of exposed floors. A tank contains the liquid and a control rod inside the sleeve passing through the tank permits operation of a control valve on a discharge port at the bottom of the tank. The liquid is fed through tubing connected to the discharge port to dispense liquid into a mopping pad. Another head consists of an elongated plate having an attached fibrous pad and a liquid distribution header which has a multiplicity of holes along one edge. A resilient connection secured between the head and the handle biases the head to fully contact the floor.
The Osberghaus Patent discloses a container for liquid floor treatment preparations adapted to be mounted on a handle wherein the container includes a return flow cutoff funnel with an inlet, and a lower outlet tube with an exit port coupled to one end of a flexible hose that is selectively kinked to prevent fluid flow from the container to the floor, or un-kinked to obtain such fluid flow. The Osberghaus Patent also discloses a liquid floor treatment applicator having a tubing for supplying a liquid treatment which is maintained in a normally kinked position, whereby a sliding sleeve located on the handle of the applicator allows the tubing to be unkinked for dispensing the liquid treatment.
The Hunt Patent is a design patent for mop handle with a reservoir and protects the shape of the mop handle as opposed to its functionality.
The Dokos Patent is also a design patent which protects the shape of the structure. The device discloses a mop with a reservoir with tubes that extend into the mop so that it can mop the floor.
The Beechuk Patent discloses the concept of a mop having a reservoir for the purpose of dispensing fluid to the mop head and it has a trigger mechanism to assist in the dispensing of fluid from the reservoir.
The Ping Patent discloses a cleaning implement having a liquid delivery system including a handle with a first and second end, a cleaning head member attached to the handle at the first end, and a sprayer nozzle preferably attached to the cleaning head member, independent of the handle, for providing increased directional control of the sprayer nozzle. In particular, the sprayer nozzle is attached to the cleaning head member, thereby enabling rotational movement of the handle to provide increased directional control of the sprayer nozzle.
The '920 Kunkler Patent discloses a cleaning implement having a protective pathway for the fluid transfer tube. In this case, the fluid transfer tube is positioned within a universal joint to prevent the fluid transfer tube from becoming entangled with the universal joint so that as fluid is dispensed from the reservoir, it can smoothly be transmitted through the mop to the floor.
The '622 Holt Patent discloses the concept of dispensing fluid to a mop head so that it can be dispensed in a controlled manner having timed release with the fluid. The novel feature of this patent concerns the nature of the cleaning pad.
The '123 Holt Patent is similar in concept to the '622 Holt Patent and has the same areas of novelty with respect to a novel cleaning pad.
The '226 Kunkler Patent protects the shape and ornamental design of the mop disclosed therein which has a fluid dispensing reservoir for fluid dispensed into the mop head for cleaning.
The Policicchio Patent also discloses an implement for cleaning a surface wherein the key feature of novelty is the nature of the mop pad.
The Chen Patent discloses a sponge mop with a cleaning tank and in this case, the nature of the mop is a roller sponge mop as opposed to a flat sponge mop.
The Fodrocy Patent discloses the concept of having liquid inside the handle itself and extending out the handle through a nozzle

which is in the handle and is above the location where the mop is attached to the handle. The unique feature of this invention employs the concept of having liquid contained within the handle itself and having a valve mechanism in the upper portio
