Abstract: A spout (10) for mounting on a liquid container (12) to provide controlled dispensing of liquid therefrom includes a manual control for stopping the flow of liquid through a pouring tube (22) and an automatic control to prevent spills due to overfilling. Manual control over the amount of liquid flowing through the pouring opening of the spout (10) is provided by a preferably tubular rod (26) having a stop (28) mounted at one end and a push button actuator (34) at the other end of the rod (26). The spout (10) includes a body (24) with the pouring tube (22) extending from one side and the push button (34) for opening the stop (28) to dispense liquid on the other side of the body. The automatic control is provided through a vent tube (30) which extends through a port in the pouring tube (22) and is connected to the tubular rod (26) which is provided with at least one hole.

Abstract: A spout for mounting on a liquid container to provide controlled dispensing of liquid therefrom includes a manual control for stopping the flow of liquid through a pouring tube and an automatic control to prevent spills due to overfilling. Manual control over the amount of liquid flowing through the pouring opening of the spout is provided by a preferably tubular rod having a stop mounted at one end and a push button actuator at the other end of the rod. The spout includes a body with the pouring tube extending from one side and the push button for opening the stop to dispense liquid on the other side of the body. The automatic control is provided through a vent tube which extends through a port in the pouring tube and is connected to the tubular rod which is provided with at least one hole. When the level of liquid in a receiving tank rises over the port, no air enters the liquid container and consequently the flow of liquid from the pouring tube is discontinued.
