Brief Patent Description - Full Patent Description - Patent Application Claims
[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 gas and which auto-close when the device is removed from the receptacle are known in the art. The problem which they have created, however, and the problem which has not been hereto adequately and economically solved, is that the user cannot easily appreciate when the receptacle has been filled, and overflow spillage occurs. [0005] A problem with the prior art is that there is no simple device which permits easy modification of present systems to automatically shutoff the delivery based on the level of liquid fill in the receptacle. [0006] Another problem with the prior art is that there is no simple way or device which would operate in a manner whereby the delivery of the liquid into the receptacle would be controlled by both the position of the delivery spout vis-a-vis the receptacle and the level of liquid fill in the receptacle. [0007] Another problem with the prior art is that there are presently many different types of nozzles and delivery containers in use and no suitable device for easily modifying these hoses, nozzles and delivery containers to make their delivery safer. [0008] It is an object of the present invention to provide a dispensing spout mountable to a delivery means such as a nozzle, a hose or the delivery neck of a dispensing opening on a container for delivering liquid from its respective delivery source into a receptacle which has a deactivation means that automatically shuts off delivery of liquid upon the receptacle being filled with liquid. [0009] It is an object of the present invention to provide a dispensing spout mountable to a delivery means such as a nozzle, a hose or the delivery neck of a dispensing opening on a container for delivering liquid from its respective delivery source into a receptacle wherein the dispensing spout has an actuation means which only permits flow of the liquid from the spout when the spout dispensing opening is inserted past the receiving opening of the receptacle into which the liquid is being dispensed, and which has a deactivation means that shuts off delivery of liquid upon the receptacle being filled with liquid. [0010] It is a further object of the present invention to provide a dispensing spout simple in design, easily constructed and simple to use. [0011] It is yet a further object of the present invention to provide a container, hose or a nozzle having a dispensing spout which achieves the objects previously described. [0012] Other objects will be apparent to those skilled in the art. SUMMARY OF THE INVENTION [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. [0014] By feeding means, it is meant whatever ever structure or device which would be necessary to feed or permit the flow of liquid from the container to the spout. For instance, it may be a nozzle, a hose or the dispensing neck of a container. By liquid source, it is meant the source of the liquid, which may be a container, a liquid pump, hose or any other source. [0015] According to another aspect of this invention, there is provided a dispensing spout with a dispensing opening for delivery of liquid from a liquid source whereby there is a control means having an activation means and a benchmark level means with a benchmark level, whereby the control means is activated to prevent liquid from pouring from the dispensing spout upon the dispensing opening of the spout being removed from a receptacle opening or when the level of dispensed fluid in the receptacle rises to reach the benchmark level, whichever event occurs first. [0016] According to another aspect of this invention, there is provided a liquid container having a dispensing spout with a dispensing opening for delivery of the liquid whereby there is a control means having an activation means and a benchmark level means with a benchmark level, whereby the control means is activated to prevent liquid from pouring from the dispensing spout upon the dispensing opening of the spout being removed from a receptacle opening or when the level of dispensed fluid in the receptacle rises to reach the benchmark level, whichever event occurs first. [0017] According to another aspect of this invention, there is provided a liquid delivery nozzle having a dispensing spout with a dispensing opening for delivery of the liquid whereby there is a control means having an activation means and a benchmark level means with a benchmark level, whereby the control means is activated to prevent liquid from pouring from the dispensing spout upon the dispensing opening of the spout being removed from a receptacle opening or when the level of dispensed fluid in the receptacle rises to reach the benchmark level, whichever event occurs first. [0018] In accordance with one aspect of the present invention there is disclosed a novel dispensing spout mountable to a liquid feeding means for delivering liquid from a liquid source. The dispensing spout comprises a casing having an inlet and a dispensing outlet; an openable and closable valve means for permitting and precluding, respectively, the dispensing of liquid from the dispensing outlet of the casing, wherein the valve means is biased closed; receptacle engaging trigger means operatively mounted on the casing and movable along the casing between a valve open position and a valve closed position; linkage means operatively connecting the receptacle engaging trigger means and the valve means; wherein the linkage means has an enabled configuration wherein the receptacle engaging trigger means and the valve means are operatively connected such that movement of the receptacle engaging trigger means from the valve closed position to the valve open position causes the valve means to open, and a disabled configuration wherein the valve means is closed, and the valve means is precluded from being re opened by movement of the receptacle engaging trigger means until the linkage means is reset to its enabled configuration; and, deactivation means for changing the linkage means from the enabled configuration to the disabled configuration, in response to detecting the proximity of dispensed liquid in a receptacle, to thereby allow the valve means to close, thus precluding the delivery of liquid from the dispensing outlet of the casing. [0019] In accordance with another aspect of the present invention there is disclosed a novel dispensing spout mountable to a liquid feeding means for delivering liquid from a liquid source. The dispensing spout comprises a casing formed with a dispensing passageway leading to a dispensing opening for delivery of the liquid; an openable and closable valve means operatively mounted on the casing for permitting and precluding, respectively, the dispensing of liquid from the dispensing outlet of the casing, wherein the valve means is biased closed; deactivation means operatively mounted on the casing for causing the valve means to close and prevent delivery of the liquid from the dispensing opening during use, when the liquid level of dispensed liquid reaches the deactivation means; deactivation means for causing the valve means to close, in response to detecting the proximity of dispensed liquid in a receptacle, thus precluding the delivery of liquid from the dispensing outlet of the casing. [0020] In accordance with another aspect of the present invention there is disclosed a novel dispensing spout mountable to a liquid feeding means for delivering liquid from a liquid source. The dispensing spout comprises a casing having an inlet and a dispensing outlet; an openable and closable valve means for permitting and precluding, respectively, the dispensing of liquid from the dispensing outlet of the casing, wherein the valve means is biased closed; receptacle engaging trigger means operatively mounted on the casing and movable along the casing between a valve open position and a valve closed position; linkage means operatively connecting the receptacle engaging trigger means and the valve means; wherein the linkage means has an enabled configuration wherein the receptacle engaging trigger means and the valve means are operatively connected such that movement of the receptacle engaging trigger means from the valve closed position to the valve open position causes the valve means to open, and a disabled configuration wherein the valve means is closed, and the valve means is precluded from being re opened by movement of the receptacle engaging trigger means until the linkage means is reset to its enabled configuration; and, deactivation means for changing the linkage means from the enabled configuration to the disabled configuration, in response to detecting the proximity of dispensed liquid in a receptacle, to thereby allow the valve means to close, thus precluding the delivery of liquid from the dispensing outlet of the casing.
