A liquid dispensing mop head comprising: a structural base of one-piece molded plastic construction having an upper surface and a lower surface, wherein the lower surface includes a plurality of hooking elements adapted to reversibly engage a textile structure in hook and loop connection, characterized in that the structural base further including at least one fluid discharge channel extending from the upper surface to a forward edge of the structural base such that fluid may flow from the upper surface to the forward edge for discharge away from the mop head ; a pliable molded polymer cover disposed in covering relation over the structural base with a space between the cover and the structural base defining a fluid reservoir, the polymer cover including at least one fluid acceptance opening adapted to receive fluid within the space between the cover and the structural base ; a stopper member normally disposed in covering, flow-blocking relation to said at least one fluid discharge channel at the upper surface of the structural base , the stopper member being operatively connected through a pivoting lever arm to a compressible spring normally applying an upward force to the lever arm and urging the stopper member downward, and wherein the lever arm operatively engages the cover such that application of a downward force against the cover compresses the spring and raises the stopper member away from the fluid discharge channel and wherein removal of the downward force against the cover causes the spring to urge the stopper member to return to covering, flow-blocking relation to the fluid discharge channel . a structural base of one-piece molded plastic construction having an upper surface and a lower surface, wherein the lower surface includes a plurality of hooking elements adapted to reversibly engage a textile structure in hook and loop connection, characterized in that the structural base further including at least one fluid discharge channel extending from the upper surface to a forward edge of the structural base such that fluid may flow from the upper surface to the forward edge for discharge away from the mop head ; a pliable molded polymer cover disposed in covering relation over the structural base with a space between the cover and the structural base defining a fluid reservoir, the polymer cover including at least one fluid acceptance opening adapted to receive fluid within the space between the cover and the structural base ; a stopper member normally disposed in covering, flow-blocking relation to said at least one fluid discharge channel at the upper surface of the structural base , the stopper member being operatively connected through a pivoting lever arm to a compressible spring normally applying an upward force to the lever arm and urging the stopper member downward, and wherein the lever arm operatively engages the cover such that application of a downward force against the cover compresses the spring and raises the stopper member away from the fluid discharge channel and wherein removal of the downward force against the cover causes the spring to urge the stopper member to return to covering, flow-blocking relation to the fluid discharge channel . <EOS>
