Dispensing spout

Abstract

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.

Description

[0001] This application claims the benefit of the filed U.S. Provisional Patent Application numbered 60 / 748,047, entitled V-Spout Auto-Closure & Auto Shutoff Venturi Spout, which is here by incorporated by reference.FIELD OF THE INVENTION [0002] The present 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. BACKGROUND OF THE INVENTION [0003] It is a problem with the present art of liquid delivery, where delivery is accomplished by a nozzle and hose configuration or from a portable container, such as is the case with gasoline, that there can be unwanted dripping and spillage. For instance, the nozzle can often still be operable after the receptacle has filled. As well, in the case of containers, with no automatic shut-off, the fuel keeps on pouring even after the receptacle is filled. [0004] Devices which permit delivery of ...

Benefits of technology

[0013] According to an aspect of the present invention, there is provided a dispensing spout mountable to a liquid feeding means for delivering liquid from a liquid source, wherein the dispensing spout comprises: a casing formed with a dispensing passageway leading to a dispensing opening for delivery of the liquid; a venturi means within the casing to reduce the pressure within the dispensing passageway as liquid flows through it during use; and a control means. The control means has a closure member for blocking and unblocking the dispensing opening; and, as well, a deactivation means. The deactivation means includes an air conduit with an air opening wherein the air conduit is 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. As well, however, it inhibits the flow of air into the dispensing passageway when the liquid level of dispensed liquid reaches the air opening and blocks access of air into the air opening. Upon that occurring, the deactivation means blocks the dispensing opening and prevents delivery of the liquid during use.
