A portable sprayer which has a resealable closure, a dispensing valve and a pressure-responsive filling valve attached to a receptacle. As the receptacle is filled with fluid through the valve, air which is entrapped in the receptacle pressurizes the container to facilitate dispensing the fluid. During filling, the inlet valve closes if the pressure of the liquid source to which the sprayer is connected exceeds that within the container by a predetermined amount. The inlet valve also closes when the filling hose is disconnected from the container in order to close the container.
