Beverage dispensing system pressurized release liquid USPA2

Abstract

A liquid beverage dispensing system having a specialized sealed container and a tube which extends from a top of the container and terminates just before the floor of the container. The tube has a one way valve that allows liquid to come up and out of the container when the valve is opened. Before the valve is opened the liquid may be a carbonated liquid under pressure. Then the valve opens upon the user's action, such as, sucking or squeezing the nipple. When the valve is opened the pressure inside of the container exerted by rising or trapped air bubbles exerts a downward force on the liquid below. The downward force thereby pushes the liquid below into and up the tube and into the user's mouth. The one way valve having unique form characteristics to permit this operation and permit other operations.

AI Technical Summary

Benefits of technology

[0017]In the present invention the valve means utilizes the pressure in the container. Some examples are embodiments shown for the present invention wherein the closing means is not in direct opposition to the opening means, and or the closing means are not in direct opposition to the pressure in the container, rather distributes it, directs it to certain points of relevance, Etc. (see embodiments). Also are utilized pivot shapes, Locations that assist in the functionality of the valve as they correspond with the internal pressure. A valve in the present invention may utilize the pressure to assist in keeping the valve open once opened and closed once closed and still the amount of energy needed by a person to open the valve is small.

[0021]The present invention used with a pressurized beverage container. The present invention can be used with a carbonated beverage, beer, wine or the like. It can also be used with a regular beverage or carbonated beverage not under pressure, simply by opening a air inlet valve, discussed later, and the tube can be used as a regular built in straw. Even then this container can prevent spillage, loss of carbonation, loss of heat. Also when used with a hot liquid it retains heat.

[0025]From the above it is clear that the straws and container for dispensing the liquid in the prior art have a limited scope. The present invention provides a comprehensive solution by addressing all of the disadvantages of previous liquid dispensing systems. The pressurized liquid dispensing system is capable of maintaining the gas pressure inside the container. The dispensing system prevents spilling of the liquid in all conditions in practice, could be cleaned and refilled, with ease of packaging and pleasing appearance. One can drink the liquid inside the container with less physical effort, an injured person can drink by holding in any orientation. It can be used for hot drinks and beverages as well. Further it could be used as a drinking utensil and a spray bottle. The product is an appeal to the thirst for novelty thereby increasing the marketability of the product.

Problems solved by technology

Simple straight rod like straws were used initially but they were very inconvenient to use.

There are many problems associated with the simple straw as well as the straws with bellows.

The opening provided on the container for inserting the straw in the container is greater than the straw diameter, so the fluid inside the container is prone to surrounding contamination at the same time there is a fear of unintentional spillage.

The process of manufacturing these components is very complex.

Mounting the straw is not so easy, the handling and packaging of the container is not friendly and it does not look good in its appearance.

Further the main problem with this tube is that the liquid inside the container may gush out of the beverage container through the tube in the conditions of excessive external or internal pressure on the beverage container.

The problem of withstanding high pressure remains unresolved.

It leads to dripping of the liquid inside the container when the container is inverted.

The spouting of liquid is possible due to excessive outside pressure or when the user is riding or driving a vehicle.

But this is not desirable and fails when the user has to apply a sucking force beyond this capacity.

This would be unmanageable.

However the drawback of these containers is that once the seal is opened it should be consumed within a limited duration of time before the carbon dioxide is released, otherwise it goes flat and tasteless.

These containers are made of aluminum and cannot be reused or refilled.

The amount of force needed in a spring to hold down the pivot against the contents would make it nearly impossible for an average person to open the valve.

If the valve closing means as embodied and described were strengthened it would have a direct affect on the strength needed for opening valves opening means making it more difficult to open, and the amount of strength that is needed to make the closing means stay closed under the relevant pressure, if the strength were added, would make the opening means very difficult if not impossible by an ordinary person to open.
