This invention relates to a spout for a hose, nozzle or a container and to a hose, nozzle and a container used to dispense liquids into a receptacle from a liquid source such as a gas container, delivery hose or pump. In each case, there is a spout means having a delivery trunk body formed with a dispensing passageway leading to a dispensing opening for delivery of the liquid; a venturi means within the delivery trunk to reduce the pressure within the dispensing passageway as liquid flows through it during use; a control means; said control means having a deactivation means, said deactivation means including an air conduit with an air opening, the air conduit being in communication with the dispensing passageway to permit the drawing of air into the dispensing passageway through the air opening when pressure is reduced by the venturi means, but inhibiting the flow of air into the dispensing passageway when the air opening is blocked or covered as the liquid level of dispensed liquid reaches the air opening and cuts off access of air into the air opening; a deactivation means to shut off the dispensing opening when the air opening is closed to inhibit air from entering during use.
