Abstract: Linked poppet valves in a liquid dispensing spout are coupled to each other and thus open and close together responsive to displacement of a valve stem for both poppet valves. The valve stem is driven by a spring loaded actuator, which acts as a mechanical interface between the valve stem and an operator's push button.

Abstract: A vent tube for a liquid dispensing spout having two, staggered opening poppets is sized, shaped arranged such that opening a liquid control poppet before an air control poppet creates a vacuum in a sealed reservoir. The vent tube diameter, taper and length are cooperatively selected such that the vacuum will draw out of the tube liquid that is trapped in it.

Abstract: A nozzle for a dispensing spout provides physically separate conduits, through which a liquid and air pass between a reservoir containing a liquid to be dispensed and a container into which the liquid is to be dispensed. The fluid and air conduits, as well as their respective opposing ends, are sized and shaped to provide an unobstructed air conduit which can carry ambient air into the reservoir at a rate that is at least equal to the rate at which liquid can flow out of the reservoir at a gravitational flow rate.

Abstract: A normally-closed pour spout is operable to pour fluid from a container to a receptacle. The normally-closed pour spout includes a fluid conduit and a valve. The fluid conduit has proximal and distal ends, with the proximal end being fluidly connectable to the container and the distal end being configured for fluid association with the receptacle. The fluid conduit forms a passageway configured to pass fluid therethrough and fluidly communicate with the container and the receptacle. The valve is operably assembled with the fluid conduit so that the valve controls fluid flow through the passageway.
