LIQUID DISPENSNIG APPARATUS
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.
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.
BACKGROUND OF THE INVENTIONLiquids, 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.
SUMMARY OF THE INVENTIONAccording 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.

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.

Referring to the drawings:
Turning now to the drawings, in which like reference characters indicate corresponding elements throughout the several views,
Top 30 includes shoulder 40 affixed to upper edge 27. Shoulder 40 is conical and slopes and narrows inwardly to rim 41 in reference to
Top 30 includes a cap 50, illustrated in
Cap 50 is applied to top 30 of container 22, which means that cap 50 is coupled to, or otherwise attached to, top 30 of container 22. Liquid in chamber 35 is poured through cap 50, by tilting filled container 22 to a pouring position. Cap 50 is considered part of top 30, or otherwise an extension of top 30. Opening 42 of container 22 fluidly couples liquid discharge mouth 57 to the interior of container 22, namely, chamber 35, and liquid discharge mouth 57 fluidly couples opening 42 to spout 51, which allows liquid to be poured from chamber 35 of container 22 through liquid discharge mouth 57 from opening 42 to spout 51 and outwardly from spout 51. Spout 51 provides a user with the ability to direct and focus the liquid pouring therefrom. Spout 51 and liquid discharge mouth 57 are, accordingly, coupled in liquid or fluid communication to the interior of container 22, namely, chamber 35.
In this embodiment in reference to
Axis X extends centrally through opening 42 and also liquid discharge mouth 57. As such, opening 42 and liquid discharge mouth 57 are coaxial in that they share a common axis, namely, axis X. Vent or vent opening 60 located between perimeter edge 53 and spout 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 of continuous sidewall 23 denoted at 23A. Side 23A of continuous sidewall 23 is considered an upper side of continuous sidewall 23, which opposes the other side of continuous sidewall 23 denoted at 23B, which is considered the lower side of continuous sidewall 23. Vent or vent opening 60 is separated from axis X by a distance D1.
Liquid dispenser 20 incorporates an air vent tube 70, illustrated in
Orifice 71 is applied to vent or vent opening 60 at inner side 54 of circumferential body 52 of cap 50. Proximal end 72 is secured to vent or vent opening 60 at inner side 54 of circumferential body 52 of cap 50 with adhesive, heat bonding, welding, or the like. In alternate embodiments, proximal end 72 may be press fit into vent or vent opening 60, or formed integrally with vent or vent opening 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 of air vent tube 70 to cap 50 forms a cap assembly, according to the principle of the invention, and air vent tube 70 is considered a part of, or otherwise an extension of, cap 50. Air vent tube 70 cooperates with vent or vent opening 60 to flow atmospheric air into the interior of container 22 concurrently with the pouring of liquid from the interior of container 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 from orifice 71 to orifice 73. Air vent tube 70 is a curved tube. Specifically, air vent tube 70 is convex along axis X toward one side 23A of continuous sidewall from proximal end 72 orifice 71 at cap 50 at top 30 of container 22 to distal end 74 orifice 73 near bottom 31 of container 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 one side 23A of continuous sidewall from proximal end 72 orifice 71 at vent or vent opening 60 of cap 50 at top 30 of container 22 to distal end 74 orifice 73 near bottom 31 of container 22. Orifice 71 at vent or vent opening 60 at cap 50 at top 30 of container 22 is separated from axis X by distance D1, which is the same distance between vent or vent opening 60 and axis X, and air vent tube 70 extends convexly in that it is curved or rounded outwardly from axis X toward one side 23A of continuous sidewall 23 of container 22 from orifice 71 at proximal end 72 of air vent tube 70 to orifice 73 at distal end 74 of air vent tube 70 near bottom 31 of container 22, and orifice 73 is separated from axis X by a distance D2, which is greater than distance D1. As such, orifice 71 of air vent tube 70 is closer to axis X than orifice 73 of air vent tube 70.
Air vent tube 70 has intermediate part 80 between, on the one hand, orifice 71 at proximal end 72 of air vent tube 70 and, on the other hand, orifice 73 at distal end 74 of air vent tube 70. Intermediate part 80 of air vent tube 70 is located between top 30 and bottom 31 of container 22, and is separated from axis X by a distance D3, which is greater than distance D2 between orifice 73 and axis X, and which is still even greater than distance D1 between axis X and vent or vent opening 60 and also orifice 71. As such, orifice 73 is closer to axis X than intermediate part 80 of air vent tube 70, and orifice 71 is closer to axis X than orifice 73 and, of course, intermediate part 80. According to the principle of the invention, this defines a proximal segment 81 of air vent tube 70 and a distal segment of air vent tube 70.
Proximal segment 81 of air vent tube 70 extends from orifice 71 at proximal end 72 of air vent tube 70 to intermediate part 80 of air vent tube 70. Distal segment 82 of air vent tube 70 extends from intermediate part 80 of air vent tube 70 to orifice 73 at distal end 74 of air vent tube 70.
Proximal segment 81 is convex away from axis X in a direction along axis X from vent or vent opening 60, and orifice 71 at proximal end 72 of air vent tube 70 to intermediate part 80 of air vent tube 70. In other words, proximal segment 81 is rounded outward from axis X along axis X from top 30 to intermediate part 80 toward one side 23A of continuous sidewall from proximal end 72 orifice 71 at cap 50 at top 30 of container 22 to intermediate part 80 of air vent tube 70 between top 30 and bottom 31. Proximal segment 81 extends convexly in that it is curved or rounded outwardly from axis X toward one side 23A of continuous sidewall 23 of container 22 from orifice 71 to intermediate part 80, which is separated from axis X by a distance D1, which is greater than distance D2 and which is even greater than distance D1.
Distal extremity 82 is convex away from axis X in a direction along axis X from intermediate part 80 of air vent tube 70 to orifice 73 of distal end 74 of air vent tube 70. In other words, distal segment 82 is rounded outward from axis X along axis X from intermediate part 80 between top 30 and bottom 31 to orifice 73 of distal end 74 of air vent tube 70 near bottom 31 toward one side 23A of continuous sidewall 23. Distal segment 82 extends convexly in that it is curved or rounded outwardly from axis X toward one side 23A of continuous sidewall 23 of container 22 from intermediate part 80 to orifice 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 from orifice 71 at proximal end 72 of air vent tube 70 to intermediate part 80 of air vent tube 70. Distal segment 82, in turn, inclines toward axis X in a direction from intermediate part 80 to orifice 73 at distal end 74 of air vent tube 70. In this regard, distal segment 82 inclines away from axis X in a direction from orifice 73 at distal end 74 of air vent tube 70 near bottom 31 to intermediate part 80, and proximal segment 81 inclines toward axis X in a direction from intermediate part 80 to vent or vent opening 60 and orifice 71 at proximal end 72 of air vent tube 70. Air vent tube 70 is fashioned of plastic, metal, or other material or combination of materials having a sufficient rigidity that air vent tube 70 will maintain its convex/rounded shape.
In use, chamber 35 is filled with a liquid, as shown in
As liquid dispenser 22 is tilted in the pouring position along vertical plane P, the horizontal liquid level passes along proximal segment 81 of air vent tube 70, as shown in
