Abstract
POSITION RESPONSIVE TWO-WAY BALL VALVE
ABSTRACT
This disclosure relates squeezably functioning dispensing and mea-suring containers, particularly to their valves. A submersible, posi-tion and pressure responsive valve is disclosed, specially disposed within a squeezably functioning container, the valve, comprising a tubular housing, a ball and two ball seats located on the opposite ends of the tubular housing, whereby the valve or valves keep the container closed in upright and downward position, reduce accidental spilling, and promote cleaning of clogged or contaminated air inlet.

Description
BACKGROUND OF THE INVENTION
It is well known, that squeezable containers havin~ a single eva-cuating aperture, if turned upside down and squeezed, will evacuate an unknown amount of liquid dependent on how hard the container is squeezed.
When it is turned uprigl~t, the air rushes into the container through the same opening until the dispensed quantity of liquid is replaced by air.
If valves are employed inside a flexible container, it will operate in an upright position to dispense liquids and, as is known, such devices have many advantageous peculiarities.
However, it has been found that during the handling of ball valve equipped, squeezably operating containers the valves have a particular property: accidental, unintentional leaking and spilling. With regard to this property, the object of this practical invention is to provide a new, better functioning type of ball valve for dispensers and to ex-tend its applicability in a greater sector of trade.

~(~571S7 DESCRIPTION OF THE INVENTION
In a preferred form, the present invention is embodied in a valve which can be used as an air or a fluid valve the valve, comprising a tubularly shaped housing, a freely movab~le ball and two ball seats lo-cated on the opposite ends of housing The seats cover less than ~
surface of the ball. The housing is large enough to assure a friction free movement of the ball from one seat to the other. In the case of an air valve, the air passageway through the center of the lower ball seat is connected to a U-shaped tube which communicates through the clo-sure member of a flexible container to the atmosphere. Similarly, the air passageway through the upper ball seat is connected to another tube which communicates with the air con-tent of the container. In the case of a fluid valve, the fluid passageway through the center of the lower ball seat is connected to a filler tube which extends downwardly to the bottom of the container/dispenser, while the fluid passageway through the center of the upper ball seat is connected to an evacuation tube which communicates through the closure member with a suitable spout or nozzle for discharge of liquid from within the container. In both an air and a fluid (or liquid) valve, the housings and connected tubes are assembled so as to be liquid and air tight, so they are submersible in the liquid to be discharged without affecting their operation.
The movements o the ball valves in thelr respective housings are directed automatically by gravitation and also by positive - negative pressures developed inside the sealed container, due to squeezing the flexible side walls of the container.
In a regular standing, or upright, position of a dispenser having both the air and liquid valves of the present invention, both valves are closed by the force of gravity causing the walls to engage the respective lower ball seats. Upon squeezing the dispenser to increase the pressure within the container, only the fluid valve opens to allow liquid to flow out the evacuation tube. After squeezing and upon release of the container, lOS~lS 7 a negative pressure develops inside the dispenser so that the relative-ly higher atmospheric pressure opens the air inlet ball valve and air énters into the dispenser.
If the dispenser is tilted downward, or inverted, both valves will be closed again by the force of gravity causing the respective balls to engage their corresponding upper ball seats. However, in this case, when the container is squeezed, the developed pressure inside the dispenser opens only the U-shaped air inlet tube to permit liguid to be forced out of the external air aperture. In this way a clogged, contaminated air inlet can be cleaned.
A dispenser having a measuring receptacle of the type disclosed in my prior U.S. Pat. No. 3,878,972 functions more accurately with the valve of the present invention because the closed fluid valve hinders any addi-tional liquid, leaking from the container into the measured amount of li-guid, during the pouring out period from the receptacle.
Dispensers equipped with the valves of the present invention are re-liable and refillable. If liquid flows into air inlet due to any reason, the fluid will be sucked back into the container during the next use.
In certain instances, or for economical reasons, a dispenser can function with one single air valve and an evacuation tube. During com-pression of the container walls the dispenser will discharge fluid and the air valve will replace the Eluid with air. When the compression ls ended, regurgitation occurs in the evacuation tube when a Eluid valve is not used but the provision of the air valve allows rapid replacement of air in the container so that the sgueezing process can be repeated, thus continuous operation is achieved. In this case moderately more compressions have to be applied on the dispenser, compared with a device operated with both a fluid and an air valve.
Despite the fact that the fluid and air valves are closed in both the upright and the inverted, or downward, positions of the dispenser, it is possible that during storage, handling, or delivery it could be exposed ~0571S~7 to shaking and pressure which could cause discharge of the liquid. To prevent leaking, it is advisable, therefore, that the container during the transfer period be sealed with an ordinary closure cap or that the fluid and air apertures be secured with one or two separate closures.
Summarizing the function of these valves, when the container is squeezed in a normal upright position it will discharge liquids through the fluid outlet and at the same time the air valve will prevent the discharge of air from the container. When the compression is halted and the container pressure released, negative air pressure develops within the container and the relatively higher atmospheric pressure opens the air valve, air then entering into the container. In the inverted posi-tion the function of the valves is reversed that is, when the container is squeezed the fluid valve prevents a discharge of liquid through the fluid outlet, but the air valve opens and liquid will be discharged through the air inlet. However, in the inverted position the air inlet tube must first be filled with liquid before there can be a discharge, and thus the dispensing is delayed so that there is no spilling due to minor compression of the dispenser. Unintentional spilling is reduced also because these valves are closed in both the upward and downward po-sition of the dispenser by the effect of gravity on the balls, therefore without compression or shaking the dispenser will not discharge any fluid.
Dispensers equipped with valves o~ the type disclosed herein are widely applicable, Eor several kinds of dispensing heads can be fastened by frictional engagement or otherwise to the evacuation tube. With differ-ent external apertures o~ the heads, the dispensers could be useful as a spray, oiling can and with purposefully modified nozzles as enema bottle, for douches, gastric lavage with antidote etc.
