Abstract
A gravity oriented liquid dispenser includes a container that defines a chamber to contain a liquid. The container has a top including a liquid discharge mouth fluidly coupled to the chamber. The container is arranged about an axis that extends from the top to the bottom of the container. An air vent tube extends through the chamber from a first orifice in communication with the atmosphere at the top of the container to a second orifice near the bottom of the container in communication with the chamber. The first orifice is located between the liquid discharge mouth and one side of the container, and the air vent tube, including the first and second orifices, is located between the axis and the one side of the container and is convex along the axis toward the one side of the container from the first orifice to the second orifice.
Description
- The present invention relates to liquid dispensers and, more particularly, to liquid dispensers for dispensing a liquid from a contained space and for promoting liquid transfer and reducing resistance to pouring a liquid from a contained space.
- Liquids, such as oils, lubricants, solvents, cleansers, beverages, sauces, marinades, liquid soaps, and the like, are often packaged in liquid containers having tops formed with liquid dispensing openings. The liquid dispensing openings are initially capped or closed with closures, such as pull tabs, stay-on-tabs, caps, twist-off caps, threaded caps, snap-on caps, nozzles, and the like. To access the liquid contents, the closure is removed or opened to open the liquid dispensing opening, and the liquid contents are poured through the liquid dispensing opening by gravity flow. As the liquid contents are poured from the liquid container, atmospheric air is drawn into the liquid container through the liquid dispensing opening caused by the pressure differential created between the interior of the liquid container and the surrounding atmosphere. This intake of pressure-equalizing atmospheric air into the liquid container through the liquid dispensing opening competes with the liquid contents pouring through the liquid-dispensing opening, which restricts liquid flow through the liquid dispensing opening and causes the liquid contents to flow turbulently through the liquid dispensing opening in intermittent spurts or glugs, which often leads to unwanted splashing and spills and a reduced ability to controllably direct the flow of the liquid contents from the liquid container.
- The prior art has provided numerous specific configurations of liquid containers with vent structures used to equalize pressure between the interior of the liquid container and the atmosphere to promote controlled laminar liquid pouring. None, however, have proven to be entirely satisfactory. Many incorporate complex and relatively expensive vent tubes formed in the liquid container. Some vent tubes extend outwardly from the container body, and are prone to breakage and snagging. Others utilize complex, multi-chambered containers with convoluted vents that interact with the various chambers for pressure equalization. Frequently, prior art liquid container vents leak when pouring liquid. Accordingly, continued improvement in the art is evident.
- According to the principle of the invention, a gravity oriented liquid dispenser includes a container that has a top, a bottom, and a sidewall that connects the top and the bottom. The top, the bottom, and the sidewall define a chamber to contain a liquid. The top is formed with a liquid discharge mouth fluidly coupled to the chamber. The sidewall is arranged about an axis from the top of the container to the bottom of the container. An air vent tube extends through the chamber from a first orifice in communication with the atmosphere at the top of the container to a second orifice near the bottom of the container in communication with the chamber, the first orifice being located between the liquid discharge mouth and one side of the sidewall of the container, and the air vent tube, including the first and second orifices thereof, being located between the axis and the one side of the sidewall of the container. The air vent tube is convex along the axis toward the one side of the continuous sidewall from the first orifice at the top of the container to the second orifice near the bottom of the container. The first orifice is closer to the axis than the second orifice. There is an intermediate part of the air vent tube between the first and second orifices. The second orifice is closer to the axis than the intermediate part of the air vent tube so as to define a first segment of the air vent tube from the first orifice to the intermediate part of the air vent tube that is convex away from the axis in a direction from the first orifice to the intermediate part of the air vent tube, and a second segment of the air vent tube from the intermediate part of the air vent tube to the second orifice that is convex away from the axis in a direction from the intermediate part of the air vent tube to the second orifice. An exterior fluid-collecting depression is formed in the top of the container and is fluidly coupled to the first orifice. The exterior fluid-collecting depression is continuous and encircles the liquid discharge mouth of the top. The liquid discharge mouth of the top is arranged about the axis.

In alternate embodiments,circumferential body 52 and rim 41 may be joined by threading, a snap or detent engagement, or the like.Cap 50 may also be integrally formed withrim 41, such as by molding. Preferably, a fluid-impervious seal is formed betweencircumferential body 52 and rim 41 to prevent fluid leakage therebetween.Liquid discharge mouth 57 is juxtaposed at opening 42, and spout 51 projects outward fromliquid discharge mouth 57 andopening 42 so as to be available for pouring liquid outwardly from the interior ofcontainer 22 poured throughopening 42 andliquid discharge mouth 57. - Axis X extends centrally through
opening 42 and alsoliquid discharge mouth 57. As such,opening 42 andliquid discharge mouth 57 are coaxial in that they share a common axis, namely, axis X. Vent or ventopening 60 located betweenperimeter edge 53 andspout 51 is located to or otherwise along one side of axis X between, on the one hand,liquid discharge mouth 57 and axis X, and, on the other hand, one side ofcontinuous sidewall 23 denoted at 23A.Side 23A ofcontinuous sidewall 23 is considered an upper side ofcontinuous sidewall 23, which opposes the other side ofcontinuous sidewall 23 denoted at 23B, which is considered the lower side ofcontinuous sidewall 23. Vent or ventopening 60 is separated from axis X by a distance D1. -
Liquid dispenser 20 incorporates anair vent tube 70, illustrated inFIGS. 5-10 .Air vent tube 70 is elongate and extends fromorifice 71 ofproximal end 72 ofair vent tube 70 andorifice 73 ofdistal end 74 ofair vent tube 70. Looking toFIGS. 6-10 ,air vent tube 70, includingorifice 71 andproximal end 72 andorifice 73 and distal end, is located to or otherwise along one side of axis X between, on the one hand,liquid discharge mouth 57 and axis X, and, on the other hand, oneside 23A ofcontinuous sidewall 23.Air vent tube 70 extends through the interior ofcontainer 22, namely,chamber 35, fromorifice 71 of aproximal end 72 ofair vent tube 70 in communication with the atmosphere at vent or ventopening 60 ofcap 50 attop 30 ofcontainer 22 to orifice 73 of adistal end 74 ofair vent tube 70 nearbottom 31 ofcontainer 22 in communication withchamber 35. -
Orifice 71 is applied to vent or ventopening 60 atinner side 54 ofcircumferential body 52 ofcap 50.Proximal end 72 is secured to vent or ventopening 60 atinner side 54 ofcircumferential body 52 ofcap 50 with adhesive, heat bonding, welding, or the like. In alternate embodiments,proximal end 72 may be press fit into vent or ventopening 60, or formed integrally with vent or ventopening 60, such as by molding. In still further embodiments,proximal end 72 and vent 60 may attached by threading, or with a detent engagement pair or other form of mechanical fastening. The attachment ofair vent tube 70 to cap 50 forms a cap assembly, according to the principle of the invention, andair vent tube 70 is considered a part of, or otherwise an extension of,cap 50.Air vent tube 70 cooperates with vent or ventopening 60 to flow atmospheric air into the interior ofcontainer 22 concurrently with the pouring of liquid from the interior ofcontainer 22 to equalize the interior and exterior pressure to provide the liquid to be poured in a continuous, steady and easily aimed laminar flow stream. -
Air vent tube 70 has a constant inner diameter fromorifice 71 toorifice 73.Air vent tube 70 is a curved tube. Specifically,air vent tube 70 is convex along axis X toward oneside 23A of continuous sidewall fromproximal end 72orifice 71 atcap 50 attop 30 ofcontainer 22 todistal end 74orifice 73 nearbottom 31 ofcontainer 22. In other words,air vent tube 70 is rounded outward from axis X and along axis X from top 30 to bottom 31 toward oneside 23A of continuous sidewall fromproximal end 72orifice 71 at vent or ventopening 60 ofcap 50 attop 30 ofcontainer 22 todistal end 74orifice 73 nearbottom 31 ofcontainer 22.Orifice 71 at vent or ventopening 60 atcap 50 attop 30 ofcontainer 22 is separated from axis X by distance D1, which is the same distance between vent or ventopening 60 and axis X, andair vent tube 70 extends convexly in that it is curved or rounded outwardly from axis X toward oneside 23A ofcontinuous sidewall 23 ofcontainer 22 fromorifice 71 atproximal end 72 ofair vent tube 70 to orifice 73 atdistal end 74 ofair vent tube 70 nearbottom 31 ofcontainer 22, andorifice 73 is separated from axis X by a distance D2, which is greater than distance D1. As such,orifice 71 ofair vent tube 70 is closer to axis X thanorifice 73 ofair vent tube 70. -
Air vent tube 70 has intermediate part 80 between, on the one hand,orifice 71 atproximal end 72 ofair vent tube 70 and, on the other hand,orifice 73 atdistal end 74 ofair vent tube 70. Intermediate part 80 ofair vent tube 70 is located between top 30 and bottom 31 ofcontainer 22, and is separated from axis X by a distance D3, which is greater than distance D2 betweenorifice 73 and axis X, and which is still even greater than distance D1 between axis X and vent or ventopening 60 and also orifice 71. As such,orifice 73 is closer to axis X than intermediate part 80 ofair vent tube 70, andorifice 71 is closer to axis X thanorifice 73 and, of course, intermediate part 80. According to the principle of the invention, this defines aproximal segment 81 ofair vent tube 70 and a distal segment ofair vent tube 70. -

Distal extremity 82 is convex away from axis X in a direction along axis X from intermediate part 80 ofair vent tube 70 to orifice 73 ofdistal end 74 ofair vent tube 70. In other words,distal segment 82 is rounded outward from axis X along axis X from intermediate part 80 betweentop 30 and bottom 31 to orifice 73 ofdistal end 74 ofair vent tube 70 near bottom 31 toward oneside 23A ofcontinuous sidewall 23.Distal segment 82 extends convexly in that it is curved or rounded outwardly from axis X toward oneside 23A ofcontinuous sidewall 23 ofcontainer 22 from intermediate part 80 toorifice 73, which is separated from axis X by a distance D2, which is greater than distance D1 and which is less than distance D3. -
Proximal segment 81 inclines away from axis X in a direction fromorifice 71 atproximal end 72 ofair vent tube 70 to intermediate part 80 ofair vent tube 70.Distal segment 82, in turn, inclines toward axis X in a direction from intermediate part 80 to orifice 73 atdistal end 74 ofair vent tube 70. In this regard,distal segment 82 inclines away from axis X in a direction fromorifice 73 atdistal end 74 ofair vent tube 70 near bottom 31 to intermediate part 80, andproximal segment 81 inclines toward axis X in a direction from intermediate part 80 to vent or ventopening 60 andorifice 71 atproximal end 72 ofair vent tube 70.Air vent tube 70 is fashioned of plastic, metal, or other material or combination of materials having a sufficient rigidity thatair vent tube 70 will maintain its convex/rounded shape. - In use,
chamber 35 is filled with a liquid, as shown inFIG. 7 . Liquid is poured from the filled verticalliquid dispenser 20 by grippingcontainer 22 and then tiltingcontainer 22 from the vertical position extending upright from bottom 31 to top 30 to a pouring position inFIG. 8 in a vertical plane P, denoted in FIGS. 4 and 6-10, with oneside 23A ofcontinuous sidewall 23, vent or ventopening 60, andair vent tube 23 positioned along vertical plane P on the upper side of axis X along vertical plane P in the direction of liquid pouring fromspout 51. Asliquid dispenser 20 is tipped the liquid level, because of the friction free nature of liquids and gravity, remains horizontal as pouring commences inFIG. 8 . During pouringair vent tube 70 communicating between the atmosphere at vent or ventopening 60 ofcap 50 andchamber 35 nearbottom 31 ofcontainer 22 flows atmospheric air intochamber 35 to equalize the pressure between the interior ofcontainer 22 and the atmosphere and liquid freely flows out ofchamber 35 ofcontainer 22 throughopening 42 and throughliquid discharge mouth 57 and then outwardly fromspout 51 in a continuous, steady and easily aimed laminar flow stream shown inFIG. 8 . Vent or ventopening 60,orifices air vent tube 70 betweenorifices chamber 35 from the atmosphere without restricting the flow of liquid out ofliquid discharge mouth 57 to spout 51. As liquid is poured emptyingchamber 35,liquid dispenser 22 is tilted further in the pouring position in the vertical plane as inFIG. 9 , and even further as inFIG. 10 , as a matter of illustration and reference. All the while, the flow of atmospheric air intochamber 35 through vent or ventopening 60 ofcap 50 andair vent tube 70 provides a rapid, continuous, controlled, laminar, and aim-able pouring.Orifice 73 atdistal end 74 ofair vent tube 70 spaced away from bottom 31 to allow ample room for atmospheric air exchange to occur. - As
liquid dispenser 22 is tilted in the pouring position along vertical plane P, the horizontal liquid level passes alongproximal segment 81 ofair vent tube 70, as shown inFIG. 8 , and past intermediate part 80 ofair vent tube 70 and then to and alongdistal segment 82 ofair vent tube 70 asliquid dispenser 22 is further tilted in the pouring of liquid from the interior ofcontainer 22 as shown inFIG. 9 and then beyondorifice 73 atdistal end 74 of air vent tube asliquid dispenser 22 is still further tilted as shown inFIG. 10 freeingair vent tube 70 entirely from the liquid contents ofcontainer 22. At the point where the horizontal liquid level reachesdistal segment 82 and also beyondorifice 73 atdistal end 74 ofdistal segment 82,distal segment 82 between intermediate part 80 andorifice 73 atdistal end 74 ofair vent tube 70 extends convexly upward from the horizontal liquid level and axis X in a direction fromorifice 73 atdistal end 74 to intermediate part 80. In other words, when the horizontal liquid level reachesdistal segment 82, as inFIG. 9 , and also beyondorifice 73 atdistal end 74 ofdistal segment 82, as inFIG. 10 ,distal segment 82 inclines upwardly and away from axis X and the horizontal liquid level in a direction fromorifice 73 atdistal end 74 ofair vent tube 70 near bottom 31 to intermediate part 80. Liquid in the interior ofcontainer 22 is prevented from flowing back throughair vent tube 70 in a direction fromorifice 73 atdistal end 74 nearbottom 31 ofcontainer 22 to orifice 71 atproximal end 72 attop 30 of container as the horizontal liquid level passes alongdistal segment 81 in a direction from intermediate part 80 to orifice 73 atdistal end 74 and there beyond asliquid dispenser 22 is tilted during pouring because gravity acting on the horizontal fluid level alongdistal segment 82 and at and beyondorifice 73 atdistal end 74 ofair vent tube 70 inherently prevents the liquid from flowing upwardly against gravity intodistal segment 82 in a direction fromorifice 73 atdistal end 74 to intermediate part 80, in accordance with the principle of the invention, thereby isolating the liquid contents ofcontainer 22 from flowing throughair vent tube 70 fromorifice 73 atdistal end 74 to orifice 71 atproximal end 72 and outwardly fromcap 50 through vent or ventopening 60 so as to prevent unwanted liquid spillage through vent or vent opening 60 fromair vent tube 70. Should liquid from the interior ofcontainer 22 flow throughair vent tube 70 fromorifice 73 toorifice 71 and outwardly through vent or ventopening 60,depression 62 collects the liquid spillage. Liquid spillage collected bydepression 62 is free to flow back through vent or ventopening 60 and back into the interior ofcontainer 22 throughair vent tube 70. - The invention has been described above with reference to preferred embodiments. However, those skilled in the art will recognize that changes and modifications may be made to the embodiments without departing from the nature and scope of the invention. Various changes and modifications to the embodiments herein chosen for purposes of illustration will readily occur to those skilled in the art. To the extent that such modifications and variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof.
- Having fully described the invention in such clear and concise terms as to enable those skilled in the art to understand and practice the same, the invention claimed is:
