BACKGROUND OF THE INVENTION
This invention relates to a package which is f or holding a quantity ox liquid, and which is adapted Jo that 9 under certain circumstances, the liquid can be dispensed therefrom at will.
Although the package according to the invention can be used for the dispensing ox any liquid which requires to be dispersed, we are particularly interested in the us ration of the package for the dispensing of a concentrate f or mixing with a delineate, ego 9 or dispensing a flavoring syrup in order to produce a carbonated beverage. That is to say, the package is adapted or connection to a dispensing system, such as might be embodied in a dispensing Michelle. Such a dispensing machine would be provided with a means or dispense no a delineate such as hot, cold or carbonated water an the 15 ` arrangement would be that upon operation of an actuator, such as a button, lever or the like, the delineate and Concentrate art dispensed in predetermined ratio, into a drinking or other vessel, to provide a beverage suitable for consumption.
In such an arrangement if desire any suitable carbonating, refrigerating and/or heating system can be used, but as will ~.~

become clear hereinafter the package according to the present invention in addition to serving as the container for hying the quantity of concentrate also uniquely is provided with particular valving arrangements thereby in particular to facilitate the dispensing so concentrate in a system as out-lined above Typically in the prior art, dispensers for mixing a concentrate, such as a flavored syrup, with a delineate, such as carbonated water, carry out their mixing in a mixing tap from which the mixed beverage is dispensed into a cup or glass Typically, both the delineate and concentrate are con-dueled through tubing to a valving mechanism at the tap which meters the amounts ox each which is dispensed and mixed at the tap, Other units 9 which have been designed particularly for in-home use, separately dispense the concentrate and carbonated water. In such devices, the user must first dispense concentrate into his cup, usually simply by judgment without any metering provided 9 and then add to the dispensed concentrate an amount of carbonated water.
In dispensing devices in which mixing is done at the tap, there are serious disadvantages. First of all, dilute ~oncenSra~e~ which is typically a syrup, remains in the area Or the tap. As a result 3 there is a likelihood of' mold formation and, unless the apparatus is regularly used and regularly cleaned, unsanitary conditions result.
Secondly, where it is desired to supply a number ox different . !

3~;Z

types of drinks the valving arrangements to couple into the tap the different concentrates becomes complex. Because of the use of tubing in the system, or if one tap is used to dispense different flavors, when one switches concentrates, owe of the previous concentrate may remain in the system and the desired drink will not be obtained initially. Devices which utilize separate concentrate and water dispensers suffer from other disadvantages, particularly the disadvantage that a consistent quality drink will not be obtained since it is generally a matter of judgment in what proportions to mix the concentrate and water. Furthermore poor mixing takes place without stirring in which case carbonation is lost Thus 9 it is evident that previous dispensing arrangements haze suffered prom various disadvantages because ox which the widespread use of carbonated beverage dispensers in the home has not come about.
In view ox these dl~icul~es, it is the object ox the present invention to provide a package for holding a quantity of liquid, particularly a concentrate for mixing with a delineate Jo provide a beverage, in which metering of the concentrate takes place in the container thereby per milting the concentrate to be dispensed directly from the container unto a drinking vessel with mixing taking place just prior to or at the entry into the drinking vessel, in I such a manner that dilute concentrate will not be present in the dispensing apparatus and the changing ox concentrates will be facilitated.

~22~35 A further object is to provide a valve which will cooperate with the package to carry out simultaneous dispense in ox concentrate and delineate and which will also conduct a pressuring gas to the container.
SUMMARY OF THE INVENTION
The present invention provides such a container or package (as used herein the wounds package and container should be considered ~ulIy equivalent) or dispensing liquid, e.g., a concentrate at a predetermined metered flow rate. To accomplish this, the package has a first part or containing a volume of a concentrate which has formed therein a first valve part, e.g., a valve seat, permitting communique lion with the volume in the first package part. A second package part has a mating valve port, e.g., a projecting part, which seats against the valve seat in the first part. This second part also contains an outlet opening so that by moving the valve projection away from the seat, fluid communication is established between the volume on the first package part and the outlet in the second package part. The first and second package parts are movable with respect to each other to electively move the first and second valve parts together and apart in order to control the flow of the concentrate from the irrupt package part through the valve and out of the outlet in the second package part. The package us also pro-voided with means or effecting a movement ox the first and second part with respect to each other and include jeans to introduce an essentially constant head pressure to the interior of the first package part independent of the amount of concentrate remaining therein. By maintaining a constant pressure within the package, and by controlling the degree of opening, i.e., the degree Or separation of the two valve parts, it thus becomes possible to dispense directly prom the package a metered amount Or the concentrate.
Control of the degree of opening the valve is necessary for a number of reasons. In the first place, dip fervent concentrates will have different viscosities. Thus, assuming the use of delineate at a predetermined constant rate and where 7 to get a properly flavored drink, a certain amount of concentrate must be mixed with that delineate, different degrees of openings will be necessary in order to accommon-date the different flow characteristics of different concern-trades due to their different viscosities, that slow being under essentially constant pressure. Secondly, changes in environmental conditions, particularly temperature can effect the viscosity and may require further adjustment. finally, although standards have been set with respect to the mixing of a delineate and concentrate such as the mixing of a syrup and carbonated water, which standards are used in making bottled drinks, personal tastes do differ and someone using the container of the present invention in a dispensing apparatus may wish to adjust it to his own personal taste.
The last two types of adjustments ~entloned are adjustments which must be done at the dispensing apparatus.

I

The first type of adjustment ire adjustment to take into account different viscosities can be accomplished either through proper dimensioning of the container parts or through a combination of dimensioning of the container parts and an adjustment in the dispensing valve in the machine with which the container is used. Providing such control by means of dimensioning at the container is thought to be preferable.
This is so because it requires no further adjustment by the user. The dispensing valve with which the container or package cooperates can then be constructed so as to bring about a preestablished amount of movement of the first and second parts with respect to each other utilizing the means provided on the package for effecting the movement of these first and second parts. On such a case, these means for effecting the movement will be so contracted and dimensioned that for this preestablished amount ox movement the swooper-lion ox the two valve parts will give the desired degree of opening for the particular concentrate contained within the package. Alternatively, the packages may all be dimensioned identically and the dispensing valve with which it cooperates made adjustable in order to allow different amounts ox motion depending on the concentrate in use. This, of course, would require a step on the part of the user of setting the valve for the particular concentrate to be used. It would, however, I simplify manufacture of the package since all could be I

identical, Although certain embodiments of the present invention are disclosed in which the means for introducing an essentially constant head pressure include means or introducing ambient air at a constant head pressure 7 the preferred embodiment is one in which dispensing takes place under the pressure ox a pressurizing gas. In such a case, it is necessary that means be provided or supplying the pressurizing gas to the container aster it has been inserted into the dispensing valve Or the dispensing machine.
Although it would be possible for this to be a separate connection to the package fed through a separate line and shutoff valve, in the embodiments ox the present invention disclosed in detail, pressurizing takes place under the con-trot of the tame valve that carries out dispensing. This valve, which as previously indicated cooperates with the means for effecting movement of the first end second parts, in the case ox a pressurizing gas, ox necessity, includes a first position where the pressurizing gas supply is cut of 9 a second position where the pressurizing gas supply is avail-able, and a third position where the dispensing valve has acted on the means or effecting movement ox the first and second parts with respect to each other to open the valve in the package and is at the tame time opening a passage or the supply Or delineate to be mixed with the concentrate in the .. . .

package. Since the dispensing valve is operatively coupled to the package in each of these positions it is necessary that movement of this valve between the first position where the pressurizing gas is not available, it shut off, permit in insertion and removal of the package, and the second position, where toe pnessuriæing gas is pressurizing the concentrate but dispensing has not yet taken place 9 requires that there be provisions either in the valve or in the package for permitting this movement without opening the valve in the package. In the preferred embodiment, this is accomplished by cooperating surfaces of the two valve parts in the package. however, an alternate embodiment is disk closed in which such is accomplished within the dispensing valve.
The fist and second valve parts can take any one of a number of different forms. For example, the two valve parts may comprise two disc like members rotatable with respect to each other, each disc containing an opening therein, one opening in emanation with the volume of concentrate in the container and the other opening in come monkeyshine with the outlet. The degree ox overlap ox the two opening and/or the so Zen of the smaller of the two openings Jill determine the flow rate of concentrate. Thus or example in such an embodiment the opening in the second valve part which contains the outlet could be made relatively large and the opening in the other container part could be .. ., ., . . . ,.. .. .. , .. ., .. .. .. , .. , ., .. . , " .,, . ;, . . .. . .

Lowe go made of a it Jo Peter the desired amount ox concentrate.
Movement of the two opening into alignment with each other, in response to a preset degree of movement of the two con-trainer parts with respect to each other, would thus result in metering the desired amount of concentrate. The dozed-vantage ox an embodiment ox this nature us that it does not easily permit additional control to take into account temperature variations or the taste ox the user. Similarly, rather than utilizing rotating movement in which two holes are aligned by rotation one can carry out a linear movement of for example a cap with respect to the neck of a bottle, each containing therein a hole Again the movement would be of a predetermined amount to align the two holes to cause flow of the concentrate.
In the preferred embodiment of the invention, the first package part comprises a bottle with a neck and the second package part a oat disposed over the neck and having means for forming an outlet opening therein Typically this will be a preformed outlet opening covered by a tear away strip or the like. However, it can also be an opening formed it the time ox use such as by punching out a prescored part to Norm an opening. The first and second valve parts it the valve seat and projection, are formed by respective parts on the neck and cap 9 in the preferred embodiment by a seat in the neck and a pro~ectlon in the cap which seats against the seat. In order to obtain the relative movement between the ISLE

two valve parts, there are cooperating surfaces on the out-side of the neck and the inside of the cap for converting a relative rotation between the cap and bottle into a linear relative motion between the cap and bottle. It should be recognized, that alternatively means can be provided for providing the linear motion directly. Means are provided on the outside of the bottle and the outside ox the cap for enabling the relative rotation of the bottle and cap.
In such an arrangement, the destined degree of separation of the two valve parts, ice., the movement of the projecting part away from the seat to give the desired flow rate ox concentrate which is properly metered to match a corresponding slow of delineate can, as noted above, be aec~m-polished in a number of different ways. In one disclosed embodiment, the nucleic ox the bottle contains normal threads and the cap is screwed on to the bottle in conventional fashion. The slope of the thread can be selected so that for a given relative rotation of the means on the outside of the cap with respect to thy means on the outside of the bottle the desired degree ox opening takes place. By changing the pitch Or the threads, for a given amount ox relative rotational movement, different openings will result to take into account different viscosities. Alternatively, all threads may be the same and the relative amount of rotation controlled in accordance with the concentrate being dispensed. Again, as noted above, this requires sitting the desired amount. of rotation at the valve with which the container is used. In this dent the cooperating surfaces on the outside of the neck and the inside of the cap are the threads on the bottle neck and the cap. In the disclosed embodiment 3 the cooperating surfaces on the cap and bottle for obtaining linear potion in response to a relative rotation comprise at least one projection on one of the surfaces and a slot on the other surface which contains a slanted portion so that a rotation is converted into a lo linear movement. Preferably 9 diametrically opposed slots and projections are provided with the projections on the neck and the slot in the cap.
Once again, with an embodiment ox this nature various means ox control ox the opening of the two valve parts are possible. For example 9 the amount of opening can be set by adjusting the angle of thy slot so that, for a predetermined amount of rotation, dire rent degrees ox opening are possible to take into account the different viscosities of the concentrates. Alternatively, a constant slope can be provided and the dispensing valve mechanism which brings about the relative rotation of the cap with respect to the bottle be capable of adjustment for different degrees of rotation.
At this point, it might be well to note that it is thought that embodiments in which a ire amount of` rotation of the valving mechanism brings about the desired degree of opening to take into account the vacuity because of , I

dimensioning within thy package is thought to be desirable.
In particular, where the valve is also making a delineate connection and dispensing delineate at the same Some design is simplified in thaw the Dylan valve portion of the valving mechanism will always be open aster the same amount of rotation or, in some embodiments, linear movement.
In accordance with one illustrated embodiment of the present invention a package contains a quantity of liquid which is to be dispensed from the package, and the package has a closure cap which serves as a valve in that upon disk placing the cap or a mounting member relative to the package to displace the cap there is established communication bet wren a dispensing outlet in the cap and the interior of the package, said cap furthermore being adapted to enable con-I section between the inside of the package and atmosphere or for connection to a supply of a pressurizing gas, such as carbon dioxide gay, which can be introduced to the interior of the package enabling the liquid to run from the package or for propelling the liquid out of the package through said dispensing outlet, when the cap is displaced relative to the package body The cap it preferably displaceable by being rotate able and is provided with a central tube which extends into the interior of the package, and serves to permit the passage I ox the air or propellant into the interior of the passage.
In one embodiment, the tube has a sealing shoulder forming the aforementioned projection which, when the cap closes the 35~

package forming the valve sea, sealingly engages an interior neck of the package, preventing flow of liquid Lo the package Jo said outlet. With such arrangement; when the package is fitted to an appropriate machine, a propellant nozzle or atmosphere vent engages the interior of the tube, establishing hydraulic connection between the atmosphere or a propellant source and the interior of the package.
The package is provided with first key means, e.g.
tabs and the cap may be provided with second key means e.g.
also a tab, these serving to engage in appropriate Casey or slots in respective first and second relatively rotatable members of a rotary valve in the machine to which the package is to be fitted Engagement between the firs key means and a kiwi in the first component, prevents rotation of the package body, while engagement ox the second key means and the kiwi in the second member enables relative rotation of the cap by means of the second rotary member.
The disclosed second rotary member also, when a propellant is to be connected to the package interior, serves as a rotary valving arrangement coupling a supply of the pro-pollinate to the interior of the package at an appropriate angular position of the second rotary member and also pro-vises a valve arrangement for the supply of delineate; erg., carbonated water to a dispensing outlet audacity the outlet prom which the liquid in the package it dispensed, and also provides a vent to enable venting of the package interior when the package is to be removed prom the rotary valve.

I
, When the package is initially connected Jo the rotary valve it is vented to atmosphere and in the sequence ox turning said second rotary member, in the first stage of turning, the supply of propellant is connected to the interior of the package and the vent is closed, prior to the opening of She package valve, and further rotation of the second member effects opening ox the package valve and therefore the discharge ox concentrate from the container through the outlet, and simultaneously a slow of delineate to the delineate outlet The two outlets may meet in a dispensing head. Preferably, however, in accordance with the present invention, they are spaced so that the respective materials discharge separately with the two streams mixing in free space as they flow into a drinking or other vessel, in order to provide a beverage for consumption.
As was briefly discussed above, during the first stage of turning, means must be provided either on the rotary member or in the package to permit such rotation without opening of the valve in the package. In the pro-furred embodiment, this is accomplished by forming the slots on one of the surfaces, in the illustrated embodiment the slot in the cap, with a horizontal portion preceding the slanted partial. Thus, during the first stage of turning the nibs on the neck ox the bottle ride in the horizontal section of the slots and no opening Or the valve takes place. During the second stage ox turning the nibs ride up in tube 310ts to open the valve. Construction ox this nature ~2~:~L3S~:

offers the further advantage that the position of She second key means, i.e., the tab on the cap, can be located with respect to the slots so as So control the amount of valve opening. In other words, this in effect sets the starting position of the nibs prior to the further rotation to open the valve. Thus, depending on thy starting point, which is controlled by the relative positioning of the tab on the outside of the cap with respect Jo the slots, the nibs ride up into the slots more or less to open the valve more or less depending on the concentrate contained within the bottle.
Alternatively, in order to permit rotation of the rotary member without opening the valve, a slot can be formed in the rotary member in which the tab rides freely through the first stage of turning. After the first stage of turning, the tab is engaged by the rotary member causing the necessary rotation to open the valve the desired amount.
With such an embodiment, in order to get the desired opening, the slope of the slot in the cap or the pitch of threads on I the cap must be properly adjusted or, the degree of movement of the rotary part must be made adjustable to take into account different viscosities. One advantage of utilizing this type of mechanism is that rather then using projecting nibs and a slot, a conventional threaded neck on the bottle I and threaded cap may be used, since there I no nerd to have a strictly horizontal rotation of the Zap with respect to the bottle. In this embodiment on particular and, for that I'''.

matter in all of the disclosed embodiments reversal of the tabs and slots is possible i.e., the slots can be formed on the cap and the tab on the rotary member. Similarly, it would be possible to form slots on the bottle and matching nibs on a fixed valve part.
The preferred embodiment has a number of specific advantages including that the cap serves the double junction of providing a connection for the pressurizing was supply, and also Or providing the package valve for controlling both the timing and metering ox the dispensing of the concentrate from the interior of the package The package is of course used in the rotary valve of the dispensing machine in inverted condition, and will preferably be ox a "throw-away' nature so that it can be disposed of when empty.
Where thy interior of the package is connected to atmosphere the portion of rotary valving arrangement used or the supply of propellant and venting it not necessary.
When the interior ox the package communicates with the atmosphere, it is arranged for gravity feed dispensing.
or both gravity feed and feed under pressure, the cap it provided with a check valve which cooperates with a plunger on the rotary valve to establish communication either with the atmosphere or gas at an elevated pressure. A central tube through which air or gas can slow into the interior of the package it I such size that flow of liquid out ox said tube is avoided while at thy same time allowing ~u~icient supply ox gas or air to replate the liquid as it is dispensed.

In gravity feed a~angements, by arranging for the end of the central tube from which the air enters the package to be submerged in the liquid, it can be arranged what the liquid will flow out of the package prom the cap outlet under constant head conditions, which means that there will be a constant rate of outflow from the package during dispensing.
This means that drinks of even consistency can be obtained without the need to apply a propellant to the liquid to drive it from the package.
160, in gravity feed arrangements, there may be a compensating space defined by the package, which space is at atmospheric pressure by being in fluid communication with the atmosphere when the package is inserted on and cooperates with the rotary valve.

Where the neck 12 meets the body 10, there are first key fins 16 which are diametrically opposed as shown clearly in Fig. 2. the package is sealed by means of rotatable cap 13~ with a lower section hazing a truncated conical shape to engage flared seal 14 and having cam groves 20 which are engaged by cam projections 22 on the outer surface of the neck 12~ the neck 12 is provided with a thicket-eyed portion AYE thereby Jo define a sealing seat surface off conical form, which is engaged by a sealing shoulder 26 of a tubular extension I which it integral with the cap 18.
The tube 2B opens through the top of the cap as shown, and at its end which is inside the body 10, it is optionally provided with a "blow-off" closure 30. An outlet aperture 32 is provided in the top surface of the cap 18 us shown inside top region where the sealing lip engages the inner surface of the truncated conical portion of the cap 18.
If reference is now made momentarily to Fig. 5, it will be seen that the sap lo is provided with a second fin .

isle:

key 34 and a conical cover 36 which has two sections of dip-foreign cone angle, leading to an outlet aperture 38, the function of which will be clear prom the description which follows. The cover 36 is in awoke integrally connected to the container in the condition in which it is shown in Fig. 5, and to gain access to the container contents 9 the cover 36 must be removed. To this end it may be provided with a suitable tear strip. In the preferred embodiment to be de-scribed below in connection with Figs. 15-22 us a cover lo is not used in which case the Sop of cap 18 will be covered with adhesive tear strip or integrally molded hinged strip incorporating plugs Reverting to Fig. 1, the package is shown in the in-use position in which it is inserted in the machine in inverted condition.

Fig. 1 shows a mounting on the machine for receive in the package as disrobe so jar. Tao port of the machine shown comprises essentially two relatively rotatable discs 40 and 42, these discs being, in this example, of the same diameter, and being located Dyne above the other. Disc 40 is provided with an aperture and Casey, as shown clearly in Fig. 2 to receive the lower portion of the package neck 12 and also the keys 16 to prevent the package from rotating relative to the disc 40 when inserted as shown in Fig. 1.

lo The disc 42 is provided with an aperture and a key way slot AYE a shown clearly in Fig. 3 to receive the key 34 on the cap 18 so that rotation ox the disc 42 will in fact effect rotation of the cap 18, while the package will be pro-vented from rotating by means of the disc 40 and the keys 16.
The disc 42 is also provided with a coupling arrangement which is shown diagrammatically in Fig. I and this arrangement comprises a nipple 44 which sealingly engage in the enlarged portion of the tube 289 and thereby communication between the interior ox the tube 28 and a pressurizing gas passage 46 in the disc I is established.

Typically in a carbonated beverage dispenser this gas will be carbon dioxide Hereafter this gas will be described in terms of carbon dioxide end carbon dioxide passages although it should be recognized that depending on the particular application other gases may be used Furthermore, venting to the atmosphere it also possible as Jill be described in more detail below.

If reference is now made to Fig. 3, it will be seen thaw the disc 42 is located in a trucker 47 which is pro-voided with three eye passages 48, 49 and 50, or the supply of carbon dioxide, or venting the package and or the supply of carbonated water respectively. Additionally, Fig. 3 shows that the disc 42 is provided with a passage 52 through which the delineate, e.g., carbonated water, can slow to a discharge outlet 54 as shown clearly in jig. 4, Jo that, in use, carbon noted water can slow prom outlet 54 while concentrate flows from the outlet 32, and these two ingredients can be mixed to produce a carbonated beverage. The mixing may take place in a mixing head forming part of the machine, or they may be, as in this example 9 discharged into the cover 36, if arranged as shown in Fig 6, from which the constituents slow, in mixed condition, into a drinking vessel 56 (Fig. 6 only).
Preferably however, the constituents will flow directly into a drinking vessel.
The open lion ox the arrangement described is as follows.
The package 10 is in~erSed in the discs 40 and 42 as shown in Fig. 1. The cover 36 is arranged as shown in Fig, 6, 80 as to catch delineate slowing from outlet 54, and concentrate slowing prom aperture 32, by positioning on a suitable mounting OX the machine, and a cup 56 is arranged to collect the flavored borage In order to dispense the beverage, thy disc 42 is rotated manually as indicated by arrow I in Fig. 3 until, irrupt ox all, thy : :" . `:'' ' ' ~2~3~
--24_ passage 46 in disc 42 sores into resister with the passage 48, thereby e~tPblishing the supply ox carbon dioxide under pressure TV the passage 46 and to the interior of the tube 28. This has the effect of blowing ox the cap 30, if installed, and the interior of the package now becomes pressurized with the carbon dioxide under constant preset pressure. Rather than providing a blow of cap which is effective only prior to first use a check valve, e.g., a split Neal valve as described below, may ye disposed in the enlarged tube 28 and opened by nipple 44. As an alternate, cup 30 may be made ox a flexible material such as rubber with a slit aye as shown in Fig. to act as a check valve.
With such a check valve, venting of the container, once pressurized is not necessary. Continued rotation of the disc 42 results additionally in the passage 52 in the plate 42 registering with the delineate supply passage 50, and delineate commences flowing through the passage 52 and out of the outlet 54. It is to be noted that during the rotation movement of the plate 42 from the time passage 46 registers with passage 48 until when passage 52 registers with passage 50, the supply ox carbon dioxide under pressure is maintained by the circumferential elongation 60 of the passage 48, as shown clearly in Fig I
At the tame time, the cap 18 is being rotated relative to the body 10 of the package, During the initial movement when the passage 46 trivial prom the pro inn shown on Fig. 3 until it registers with the passage 48, there is no downward movement Or the cap 18 relative to the neck 12 .. . ..... . . . .... . .... . .. ... ..... .. . .. . . . ... . ... ... .. . ..

of the package, but during the next stage of angular movement Leo up to the point of the passage 52 registering with the passage 50, the cap 18 is moved downward on the neck 12 where-by the tube 28 is moved downwards from the position in Fig.
10 This has the effect Or unseating the tube sealing seat 26 from the neck sealing seat AYE, and concentrate can no and does flow past the sealing shoulder 26 and out of the outlet 320 The flowing concentrate and flowing delineate streams are collected in the cover 36, it used, and are mixed to provide lo the drink which is caught in the cup 56. Preferably mixing is done in free space as the streams enter the cup I and not in a cover 36. The degree to which the cap 18 is rotated, and therefore the degree to which the sealing shoulder 26 is moved away prom the seat AYE is dictated by the gemming arrangement between the projections and grooves 22 and 20 inter-connecting the cap and neck. Clearly ? the amount of downward movement can be selected to suit the viscosity of particular concentrate contained in any particular package so that the desired ratio of concentrate and delineate will flow into the cover 36, to provide the most satisfactory beverage.
Flavoring strength control may also be achieved by initially setting the rink 40 by rotating it relative to ring 42 to a predetermined, marked, angular position. The disc 42 may be provided with a suitable hand grip or linkage system to cause it Jo be turned as de~cribed9 and the turning action ..
of the disc 42 as indicated by arrow 58, may be against spring action to ensure that when the disc is released, it will rotate in the opposite direction back to the intermediate position in which the carbon dioxide supply passage 48 and the passage 46 are in register so that the package remains pressurized, but the flows ox concentrate and delineate are terminated. Of course, it will be necessary TV provide suitable sealing arrangements to ensure thaw the equipment does not leak either delineate, pressurizing gas or concentrate when in use. When it us described to remove the package from the machine, the ring 42 it returned to the initial position, where the passage 46 register with the vent 49 and the interior ox the package is vented to atmosphere and the package can easily be removed.
In the case of a cap 30 with a slit aye, venting is not needed and a check valve may be installed in the carbon dioxide line, the valve being opened only in response to a package being inverted in the machine.
Referring to Figs. 7 and 8, in these drawings are shown two alternative sealing constructions a between the internal tube 28 and the neck ox the container. It is to be noticed that where possible the same reference numeral as have been used in previous inures are used in Figs. 7 and 8.
In the arrangement of Fig 7, the tube 28 it pro-voided with a reduced diameter valve portion 80, and where the portion 80 widens to the larger diameter at the lower end thereof, it engages in a sealing Passion against an in-equine mounded plug 82, sealingly and friction pitted in the package neck 12. In use, when the cap 18 it rotated as 3~7~

described previously and roves away from the body 10, the reduced diameter portion 80 moves to the dowsed line position shown in Fig. 7, so thaw the concentrate can slow past the cap I and the reduced diameter portion By of tube 28.
In the arrangement shown in Fig 8, the tube 28 has a flexible bulbous portion 90 which ~ealingly engages the shoulder AYE of the package neck 12, and when the cap 18 is moved away from the body 10l the bulbous portion 90 changes shape as shown in dotted lines in Fig. 8, whereby lo the concentrate can flow past the tube 28 and past the now deformed bulbous portion 90 to flow out of aperture 32. When the cap 18 is once more screwed towards the body 101 in either the Figs. 7 or 8 embodiment, sealing is once more established between the tube 28 and the shoulder in the case 15 I Fig. 7 embodiment or the bulbous portion in the case of Fig. 8 embodiment The arrangement shown in Fig. 9 is essentially similar to that shown in Fig. 7 in that the tube 28 is again provided with a restriction 80, but in this case, the plug 20 82, in the closed condition ox the container, frictionally and sealingly engages the larger diameter portion of tube 28 at the lower end thereof. As the cap 18 is unscrewed 7 the aperture region of the plug 82 encircles the restriction 80 7 creating fluid communication between the interior of the I package and the outlet aperture 32, 30 that concentrate can slow from the container whiz delineate also flows as previously described. In each of the embodiments illustrated in Figs. 7 .. .... . .. ...... .. .. .. ....... . . ..... . . ... .. . . .

Lo I
and 3, the cap 18 is not easily removable by virtue of the upper portion of the tube 28 being of enlarged diameter Turning now to Figs. 10 and 11, the embodiment of the invention illustrated in essay Figs. is different from the previously described arrangements, on that the cap is integral with the package body, but the operation of the container bears similarity to the operation of the arrange-mint described in Fig. 8. In the Figs. 10 and 11 arrangement, the body it again illustrated by numeral 10, but numeral 720 lo illustrates an integral combined neck and cap, this cap being integrally connected to the container body 10 by means of an inwardly wasted portion 122 which sealingly engages a but-bus portion 90 of the tube 28 which again as shown is integral with the cap 120. Again the outlet aperture 32 is provided in the cap, but in addition the cap has outwardly directed integral bayonet pins 124 which slide through slots or Casey AYE and AYE in the members 40 and 42. The slots AYE extend through the entire depth of the member 40 while slots AYE extend only as jar as circumferential cam slots 42B. Fig. 10 shows the arrangement immediately after the package has been inserted in the apparatus when the member 42 is rotated so a to eject discharge ox concentrate from the package by virtue of the pins 124 engaging in the air-cum~erential cam slots 42B, the zap 120 is forced downwardly I in Fig. 10 and 11 as indicated by arrow 126 causing the cap 120 to move away from the boy 10, the member 40 preventing any bodily movement of the package in a downward direction --2g-This action has the effect of lowering the tube I and also of opening up the west portion 122 as shown clearly in Fig.
11 so that there is established a path of fluid communication as indicated by the arrows in Fib 11 between the interior of the package and the outlet 32, which condition will pro-vail when I course the other components of the apparatus cause discharge of the delineate simultaneously to produce a beverage in a container as hereinbe~ore described. The advantage of the package illustrated in Fox and 11 is lo that it can be sold as a completely sealed unit, outlet 32 being for example covered by means of a tear strip or rip cap When the member 42 is rotated in the opposite direction i.e., to terminate the flow of concentrate and delineate the resiliency of the wasted portion 122 assists in returning the cup 120 to the Fig. 10 position in which the bulbous portion 90 once more Lucy the interior of the package body from the outlet 32, and flow of concentrate ceases. It is appreciated that other embodiments of the invention based upon the principle described with reference to Figs. 10 and Jo 11, own be devised. For example the bulbous portion 90 may lie above the wasted portion 122i or indeed the tube 28 can be ox a construction as shown in Fig, 1, jig. 7 or Fig I
In the already described embodiments of the invent lion, a propellant gas is used to drive the liquid prom the I package through the outlet aperture 32, when the cap 18 is displaced. It is also possible to arrange within the scope ox the invention or the package to be a gravity feed" disk -Jo-penning device, and the embodiments ox the invention shown in Figs. 12 Jo 14 are the so called gravity weed arrangements Referring to the embodiment shown in Firs 12 and 13, the body of the package is represented by numeral 200, and like the embodiment in Fig. 1 is provided with a reduced diameter neck portion 202, the mouth ox which forms a seal.
The Cup 204 it connected to the neck in a fashion similar to that already described, and it provided with a narrow central tube 206 having a sealing shoulder 208 which, in the closed lo position of the package shown in Fig. 121 sealingly engages the reduced diameter neck portion 202. In addition, the tube 206 is closed by means of a check valve 210 in the form of a split seal which, in the in-use position shown in Fig. 12 is opened by a venting nipple 212~ The cap, similar to the previous embodiments has a discharge outlet 214 for the disk penning of the concentrate therefrom. A cylindrical insert 22B retains the split Neal valve in place and an 0 ring 230 seals between it and nipple 12.
The package described is operated in a manner similar to that described in relation to Figs 1 to 6, except that there us no supply of propellant gas to the inside of thy package 200. When the package is in She transportation condition, the split seal valve 210 is ox course closed and the cap 204 closes the body 200. when the package is to be used it is inverted as shown in Figs. 12 and 13, and is fitted to the appropriate part in the dispensing Ann, for example as illustrated in Fig 1 9 2 and 3, and at the time of fitting the nipple 212 opens valve 210. If now the cap 204 is rotated relative to the body 200 to cause the 3t~2 shoulder 2n8 to unseat from the neck portion 202, the con-cent rate can run pat the shoulder 20~ and out the aver-lure 214. At same time, as shown in Fake 13, which shows the open position of the package, air is drawn into the interior of the package through the tube 212 as represented by the bubbles 216 in Fig. 13 to make up for the liquid which flows from aperture 214 as indicated by arrow 218 in Fig. 13.
Because of this arrangement, in fact the liquid is dispensed prom aperture 214 under the influence of a constant head lo represented by the head shown in Fig. 12, because at the top of the nipple 212 there exists, and always exists, at-mospheric pressure, and indeed in the head space 220 in the container there exists a sub-atmospheric pressure, represented by the symbol pox which is less than atmospheric pressure.
The advantage of this construction is that it simplifies the construction of the package and rotary valve e g., no propellant source connection is required, it is not necessary to vent the package prior to removal ox some, and the cost of the carbon dioxide to propel the concentrate prom the package is avoided.
There it one possible difficulty with the arrange mint of Figs. 12 and 13 which arises if the package it used in an environment in which there are significant temperature fluctuations. For example it the temperature of the environ-mint increases, when the pressure in the head space ~20 will increase due to expansion ox the was therein. This could cause backfill ox concentrate through the nipple 212, which would be undesirable In a modification wherefore, as shown in Fig. 14, the package is provided with an internal .

compensating vessel 222, which is an inverted, closed cup, integral with the reduced neck portion 202, but provided with a compensating aperture ~24 connecting the interior of the compensating vessel with the interior ox the package body 200. It is to be noted aye the compensating vessel 222 and the reduced neck portion 202 are integral, but form a separate unit from the body 2000 The unit is in fact frictionally and sealingly engaged in the neck of the body 200. The mode of the operation of the package shown in Fig. 14 is thaw when the package is closed, as shown in Fig. 14, the liquid inside the body 200 flows through aperture 224 and fills up the inverted compensating vessel to the level 226 which is coin-cadent with the uppermost point of the aperture 224.
Atmospheric pressure prevails at level 226 by virtue of the connection through the vent tube 212 which means that the sum of the pressures ox being the head of liquid above the said liquid 226 and the pressure in the head space 220 will equal atmospheric. The liquid will therefore be dispensed from around the tube 206, when the package is open for the dispensing of liquid through the aperture 214. With this arrangement, if there is a change in temperature, for example to cause the was on the head space 200 to expand, this ox-pension is accommodated for by an increase ox the level 226 within the compensating chamber, and there Jill be no us-wanted discharge ox liquid through the nipple 212~
Furthermore the type ox constant head system disclosed in my expending application Serial No can also be used in conjunction with the package Or the present invention.

Fig. I is an exploded view and Fig. 16 a plan vie of a preferred embodiment Of a dispensing valve according to the present invention. Delineate, e.g., carbonated water is supplied to a passage 99 in the manifold 77. This passage connects with two smaller passages 101 and 103, which lead to outlets 105 and 107~ in the portion Or the valves which is integral with the manifold. At each of the outlets an O-ring seal 109 is provided. Carbon dioxide at reduced pressure e.g.
40 psi is fed through a pressure reducing valve 111 which is built into the manifold 77 9 where the pressure is reduced to 5 psi. From valve 111 the carbon dioxide flows in a passage 113 to which are connected two passages 115 and 117~ which lead to elongated openings 119 and 121 in the portion of the manifold which come pulses part ox the v level Again in each case an 0-ring seal 123 ox neoprene or the like is inserted. Although the manifold Jan be made Or various materials, a plastic material is preferred in view of its insulating properties.
With such plastic materials the manifold can be molded and any necessary machining carried out to form the various passageways.
The construction of the dispensing valves AYE
and 79B~ can best be understood first with reverence to Figs. 155 aye 15b and lo 3 in addition to Fig. 16. In the illustrated embodiment each valve is made up of four basic parts These include a base portion lBl I
which is molded as part ox the manifold 77. However, it should be recognized that such base portions can be made separately with appropriate connections or a carbon dioxide pressure line 117 and a water inlet line 103.
Since both valves are identical, only the right hand valve 79B will be described in detail. The base 181 of the valve is a member containing a large cylindrical bore 182. At the bottom of this bore is located the inlet opening 121 for the carbon dioxide with its O-rlng seal 123 and the inlet opening 107 for the delineate e.g., carbonated water with its O-ring seal 109. Also located in the base portion is a vent hole 1~3, an opening 185 through which the concentrate, e.g., a syrup, will be dispensed in a manner to be described below, and a drain passage 187 or the residue of Dylan, e.g., carbonated water, after it has passed through the valve. Inserted into the bore 182 is a central rotating valve member 189. It is supported within the bore 182 for rotation therein in response to operation ox a handle 191 and seals against O-rings 109 and 123. Overlying the central rotatable member is an adjustment disc 193. The adjustment disc remains essentially fixed but is adjustable to wake into account die rent environmental conditions in metering ox the concentrate. This adjustment is accomplished by an adjusting screw 195~ As can bet ye seen prom reverence to Figs. 15 and 16, the adjusting screw includes a knob ., - :

2 5 . -35-196 on the end of a shalt 198. The shaft passes through and is rotatable within a threaded plug 197. The threaded plug 197 is screwed into a cover portion 201 ox the valve which fits over and retains in place central member 189 and adjusting disc 193. Near the end ox the shalt 198 is a worm gear 199 which is secured thereto.
When inserted unto the cover portion 201~ the end 203 of the shaft 198 is supported for rotation in a bore 207, as best seen in Fig. 16. The worm gear 199 is exposed through an opening ]94 and engages appropriate threads 209 on the adjustment disc 193 permitting a limited degree of rotation thereon. Once adjusted by the adjust-mint screw 195~ however, the disc 193 remains mixed.
As shown in Fig. 15, container 81 includes a body in the form of a necked bottle 238 and a cap 230.
Dispensing of the concentrate from the container 81 is in response to a relative rotation of its cap 230 with respect Jo tabs 211 on the neck ox bottle 238. This opens a Allah in container 81 and carries out a metering action in a manner to be described more sully below. To accomplish this rotation, the cap 230 also contains a tab 213. The tab 213 engages in a notch 215 in the central member 189. The tabs 211 engage in notches 217 in the adjustment disc 193. The central valve member I 189 is arranged to rotate a given amount to open the metering valve within the container by rotating cap 230 which is engaging the notch 215 on the central valve it member 189~ wine adjustment of this metering is possible by means of the adjusting screw lg5 which increases or de-creases the initial setting Or the position ox the cap 230 relative Jo the body 238 so as to vary the rate of slow of concentrate prom the container upon a preset and subsequent rotation ox cap 230.
The dispensing valve performs three separate unctions It performs a function of venting the con-trainer, a function of pressurizing the container with the low pressure carbon dioxide and a function of causing the simultaneous dispensing ox concentrate end delineate. The central valve member 189 contains a central bore 219 at the bottom ox which there is provided a cylindrical member 221, containing a partial bore 232 in the upper portion thereof and supported by three struts 223. One ox the strut 223 contains therein a passage 225 which communicates with the bore 2321 The other end of the passage 225 is brought through to the bottom of the central valve member 189 and at a location permitting alignment with vent hole 183 and outlet 121 in the base member 181 ox the valve. As best teen prom Figs. 17 and 18 inserted within the bore 232 is tubular member 227. This tubular member communicates with a tube 229 extending to the bottom Or the container 81 (which will be he top with the container 81 in the inverted positron shown) or the purposes ox venting and pressurizing, in a manner to be more sully described below.

;. :;

I

With reverence to Fig. aye, the position ox the valve with the handle 191 sully to the left is shown. In this position containers are inserted into and removed from the equipment and the passage 225 is aligned with the vent hole lB3 permitting venting of the container 81 through tube 229, tubular member 2273 passage 225 and vent hole 183. This corresponds to the cross sectional view of Fig 17~
In the position shown in Fig 15b, which is a quiescent position of a container in the machine, the interior Or the container is pressurized, but there is no slow of concentrate or delineate from the machine, and the container cannot be removed from the machine, handle 191 is centered, the passage 225 is overlying the opening 121 and is sealed by the 0-ring seal 123. This admits the low pressure carbon dioxide to the passage 225 from whence it can flow through the tubular member 227 into the container through tube 229, to pressurize the container with a constant pressure. In this position, the delineate outlet 107 with its seal 109, us still covered by the bottom of central valve member 189. This corresponds to the cross section ox Fig. 18.
Finally in the position shown in Fig . lo 3 which is the dispensing position in which concentrate and delineate slow from the machine, and the container cannot be removed the handle 191 is all the way to the right D and an inlet opening 231 in central valve member 189 is aligned with the opening 107 Jo peril a flow of delineate e.g. 3 carbonated water, through and out of the valve At thus time because ox the elongated opening 1213 the passage 225 is still in communication with the carbon dioxide supply to maintain pressurization ox the canonry this corresponds to the cross section of Figs. 19 and 20. Movement ox the handle 191 to the right takes place against the biasing force of a spring 233 which is arranged Jo return the handle 191 to lo middle position.
Once pressurized if it is desired to remove the container with the concentrate and replace it with another it is only necessary to move the handle 191 to the position shown in go aye, to vent the container 81 to permit relieving the pressure wherein and allow removal.
The cross section of Fig. 20 shows the passage 225 still aligned with the opening 121 during dispensing.
The passages for the carbonated water on this position, ice. J the position also shown on Fig. 15c is illustrated by Fig. 19. Shown is the passage 103 which communicates with the opening 107 which is surrounded by the O-ring seal 109, sealing against the rotary valve member 189 and communicating with the passage 231 therein. The delineate thus slows into a pressure reducing chamber 235~
and thence out ox a spout 237 which l s carried by member 189. It will be appreciated that spout 237 thrower , . , moves with member 183 and because it precuts under the base 181, the base is provided with a lobe cutout AYE
lug 15)~ to permit the spout to so move. The spout is directed at an angle to cause mixing of the delineate and concentrate in a manner to be teen more clearly below in connection with Fig 20. Chamber 235 is designed for minimum agitation ox the delineate to prevent excessive loss ox carbon dioxide. The dimensions ox chamber 235 and spout 237 are such that an adequate slow of delineate is maintained and that, with a predetermined delineate pressure, the outlet flow rate is su~ficlent to obtain the necessary mixing with the concentrate without excessive roaming, When the handle 191 returns to the position shown in Fig. 15b3 the passage 231 overlies the I drain passage 187 which has a downward slope. Thus, any delineate remaining in chamber 235 can drain into a glass or cup placed below.
Referring now to Figs. 18 and 20~ it will be seen that the bottle 23R has a plug 239 in its neck.
I The plug contains a central bore 241 having a sloped portion i.e., of somewhat conical shape, 243 at its inner end. There is a central passage 245 through the inner end of the plug. The plug is of generally solenoid-rival shape and is press pitted into the neck 247 of the bottle 238. Alternatively it can be molded as part ox the bottle 238. At its outer end the plug contains a circumferential Lange 249 which extends beyond the neck 247 of the bottle. Placed over the neck ox the bottle is the c p 230. The cap Cantonese in its central portion, a cylindrically shaped member 251 which term-inmates in a conical section 252 a its inner end.
Conical section 252 abuts against the tapered conical section 243 of the plug 239. Inwardly extending member 251 contains at the inner end thereon, a bore 253 into which is inserted the dip tube 229. the dip tube extends through the opening 245 in the plug with a spacing. At the outer end of the cap, on the center eureka, is a larger bore 255 extending into member 251 and kimono acting with bore 253. At the inner end of this bore check valve 257 is disposed. In the case of the present embodiment the check valve is in the form ox a split seal valve. However any other type of check valve can be used. The split Neal check valve is held in place by a cylindrical insert 259. The witting 227 which is surrounded by an 0-ring seal 260 to seal inside the cylindrical insert 259 in cap 2309 it inserted into the center ox the insert 259 and acts against the check valve 257 to open it permitting carbon dioxide to flow into the container through the dip tube 229. In the portion Or the container above the plug 239, the con-cent rate will be contained. The cooperation between the I plug 239 and the inward projecting member 251 on the cap perform the valving action needed to dispense a metered amount Or concentrate. the conical Ursa 243 of plug I

239 forms a valve sea for the conical tip ~52 of member 251. It can be teen, that movement ox the member 251 away prom the plug 239 will permit a row of concentrate around the dip tube 229 and into the area between the member 251 and the plug 239.
What happens when such movement occurs is illustrated by Fig. 20. As shown by the arrows 261, concentrate slows around the dip tube 229 and into a space 263 between the plug 239 and the member 251. At the same time the flange 249 has been lifted away from the cap 230 and an opening 265 formed in the cap is exposed. In the closed condition, a double seal is provided. First there is the seal between conical surfaces 252 and 243, second us the seal between flange 249 over opening 265. With the cap 230 moved downward, concentrate can now slow through opening 265 under the pressure which is maintained in the container because of the C02 and drop through a g p between the struts 223 shown in Fig. 163 and Fig. lo into a cup 267, placed below the dispensing valve. The flowing concentrate 269 slows essentially straight down. The dlluent, erg,, the carbonated water slows prom the spout 237 at an angle intersecting the flow Or concentrate in free space and mixing with it prior to reaching the cup 267.
As noted above the valve within container 81 is opened in response to rotation ox its cap 230 with respect to its body 238 brought about by rotation ox 35~

central valve member lB9 with respect to adjustment disc 193 which, once adjusted by adjusting screw 195~ remains mixed during operation. The manner in which the rotary motion ox the central valve member 189 brings about a separation of the plug 239 and the member 251 in the cap 230 is best illustrated by Figs. 21 and AYE. In jig.
21, the insertion of the tabs 211 into the slots 217 in the adjustment ring 193 is illustrated. As described above, this holds bottle 238 mixed. Furthermore, the manner on which the tab 213 on the cap 230 is inserted into the slot 215 to cause the cap 230 to rotate with central valve member 189 is also evident. The rota-tionship between these parts is also illustrated in Fig I and Fig. 16.
As illustrated in Fig 219 the neck 247 Or bottle 238 contains a pelf ox opposed projecting nibs 271. these projecting nibs Kit into cam slots or grooves 273 wormed on opposite sides ox the inside ox cap 230.
A view ox a portion of the cap 230 unfolded is shown in Fig. aye. On this figure, the shape of the slots 273 is evident. The slot contains a horizontal portion 275 hollowed by a sloping or angled portion 2?7.
It can be seen that, as the central valve member 189 us rotated, it carries with it the cap 230 because ox the insertion Or the tab 213 on the ought 215. Rotation while in the horizontal portion 275 of thy slot will result in no relative linear up or down motion between the cap 230 and the bottle 238, and thus the valve formed by the plug 239 and the member 251 remains closed.
Travel in the horizontal portion 275 takes place between the positions Or central valve member 189 shown in Fig.
aye and 15b. However, with further rotation to the position shown in 15c the nibs 271 will begin to move into the angled portion 277 causing the projection 251 to move away from the insert 239, in order to reach the position shown in Fig. 20 3 to dispense the concentrate at a preset metered slow rate. It Jill be arranged that the nibs 271 will be in a position in the said straight portion 275 intermediate the ends thereof when the container is in the machine and the rotary valve is in the position shown in Fig, aye, to enable the ring 193 to be adjusted in both directions jut that movement of the rotary valve to the Fig. 15b poslkion will not cause the nibs 271 to ride up the angled portions 277. Also, the angled portions 277 should be ox suf~lcient length that the nibs tie between the ends ox the angled portion 277 when the machine is in the Fig. 15~ position, again to permit the said adjustment of ring 193.

Also shown in cross section in Fig. 21 is the worm gear 198 of the adjustment cry 195 ox Fig. 16 I and 150 It is evident that the dispensing action, lye.
the opening Or the valve in the container takes place because ox a relative movement between the cap 230 and the bottle 238. During normal operation, the bottle ?38 is held mixed because of the insertion Or the tabs 211 in the slots 217 in the adjustment ring 193. Thus, during normal dispensing, the starling poison i.e.
when in the positron of Fig. 15b, of the nibs 271~ in slots 273 and the degree of rotation Or cap 230 by means of the tab 213 in the slot 215 in the central valve member 189 determines the degree ox opening of the vowel i.e., the amount Or travel ox nibs 271, in the sloping portion 277. This total amount of rotation movement of cap ~30 is fixed, in that movement ox the lever 191 of Fig. 15c is limited by the spring 233.
Normally, or a siren concentrate, the tab 231 on cap 230 will be positioned as explained herein, with respect to the slots 273 during manufacture to give a combined horizontal and sloped movement which will result in the desired amount of valve opening based on the viscosity of the concentrate at a standard ambient temperature, e.g., 20 C. Alternatively the position of tab 213 with respect to slots 273 may be fixed and the angle of angled portion 277 ox slots 273 varied to accommodate materials with different viscosities. However, it the drink dispenser is operated under ambient conditions where a higher or lower temperature exists this will effect the flow rate for a given opening of ye valve.
For example, although in the temperate climates a temperature close to 20 C. will normally be maintained in wintertime, in the summertime temperatures concede-.. . , . . . . ... ,, , .. . .. . , . " .. . . . . .. . . . .

I
drably higher may occur. The higher temperatures in many cases will lower the ~iscoslty of the concentrate and too much concentrate may be dispensed. The adjust monk screw 195 is utilized to solve this problem. If the user finds that too much or too little concentrate is being dispensed the adjustment screw can be turned.
This rotates the adjustment ring 193 and in effect causes a relative rotation between the cap 230 and bottle 238 to bias the nibs 271 in one direction or the other. In turn this means that for a given rotation of the central valve member 189 the nibs 271 will move up the angled or sloped portion ~77 a greater or lesser extent. This in turn will control the degree to which the valve is opened. To enable the adjustment to take place, the 510ts 277 must, as explained herein, be of su~icient length.
For operation, low pressure, egg 5 psi, carbon dioxide will be available in the passage 113, and, carbonated water under pressure will be available in the passage 99. Thus a each of the valves a supply of carbon dioxide will be available at the outlets 119 or 121 and a supply ox carbonated water at the outlets 105 and 107. Containers ox the desired concentrate are then inserted into the dispenser. For example the curl-cent rates may comprise a syrup or making owe drinks such as a cola, orange soda, root beer, etc., or can comprise or example, concentrate to make quinine water ,

3 5 2 and so forth. In an alternate embodiment where water is not carbonated, the concentrate could be a fruit juice concentrate or where it is desired to make a hot drink, for example, a coffee, tea or hot chocolate concentrate.
With the valve in the Fig. aye position, the container 81 with the concentrate is inverted into the valve or valves (the illustrated embodiment includes two valve mechanisms; however a single valve or more than two could be provlded)0 It is inserted so what the tabs 211 are in the slots 217 and the tab 213 inserted into the slot 215, as best seen prom Figs. 15 and 21. As it is inserted the member 227 will open the check valve 257 fig. 20). At this point, the handle 191 will be in the position shown in Fig. aye and the container vented.
This will bring the dip tube 229S which is in commune-gallon with the inside of the container into commune-cation with the vent hole 183 through the passage 22 shown on Fig. aye Next, the handle is moved to the position shown in 15b~ Now the passage 225 is lined up with the outlet 123 and carbon dioxide passes to the fitting 227 and through the check valve 2~7 and the dip tube 229 into the bottle 238 to pressurize it. During the movement between the position ox Figs aye and 15b~ the nibs 271 move I the straight section 275 ox the slot 273 in the cap 230.

When it is desired to dispense a drink the handle 191 is pushed to the right from the Fig. 15b position to what shown in Fig. 15c against the force of the return sprln~ ~33. In this position, the channel 225 is still fined up with the opening 121 and the contrary remains pressurized. The water outlet 231 lines up with the opening 107 and Coronado water is dispensed from the spout 237 shown on Figs. 19 and 20.
The nibs 271 have now moved into the slanted section 277 of the slot 273 in the cap 230. This results in the cap being moved downward so that the member 251 moves away from the plug 239, opening the metering valve for the concentrate which now slows in the direction of the arrows 261 shown on Fig. 20 into the space 263 and thence out the hole 265 in the cap and down toward a cup 267 in a stream 269. The downward flowing stream 269 intersects the stream 270 ox carbonated water in free space causing the two to intimately mix as they are dispensed into the cup 267~ When the desired amount ox I drink has been dispensed 9 the handle 191 it released and returns to the position shown on Fog. 15b. The bottle 238 remains pressurized, but the flow of concentrate is stopped because of the closing ox the valve therein and the slow ox carbonated water stopped because ox the movement ox the outlet 231 away from the opening 107l Any waxer let in chamber 235 or inlet 231 ox Fig. 19 can drain both through spout 237 and drain outlet 187 to it 'r3 I

completely drain all delineate. From this point on additional drinks can be dispensed simply by moving the handle 191 to the position shown in Fig. 15c.
Assume for the moment that the two concentrate 5 containers 81 contain respectively cola and diet cola.
Assume it is now desired to dispense quinine water One of the containers 81 must thus be removed and replaced with another containing a qulrline water concentrate.
The container 81 to be removed is, ox course, pressurized.
To relieve the pressure in the container 819 the handle 191 is moved to the position shown in Fig. aye. In this position the container is now vented, venting taking place through the passage 225 and the vent opening 183.
With the pressure relieved on the concentrate container 81 it may now be removed. As it is removed, referring to Fog. 18, it is evident that once it is listed upward and the fitting 227 is no longer acting against the check valve 257~ the check valve 257 will close. this prevents any possibility of the concentrate getting into and dripping out of the dip tube 229. The new container is then put into place crier which the steps described above are hollowed.
Typically, the cola concentrate will be a relatively thick syrup whereas the quinine water con-cent rate will be relP~ively thin this rulers dirrerentdegrees of opening ox the valve made up by the member 251 and plug 239. The necessary metering which must be ... ... . .. . .. . .. . . .. ... . .. ...... .............. . . .
. '' .

so carried out is accomplished by adjusting the p~sl~loning Or the tab 213 with respect to the slot 273 on cap 230 during manufacture. In other words, in the rest position, referring to Fig. aye, for a cola syrup the nib 271 will be close to *he angled section 277 but not so close as to cause flow of concentrate from the container when the rotary valve is in the Fig. 15b position. On the other hand, for something like quinine water it will be placed further to the left so that, with movement ox the valve to the Fig. 15c position, the nibs 271 will only ride up on the angled portion a small amount. Alternatively, this control can be obtained by using die rent angles on the angled portion 277.
The various advantages b~kh with respect to construction and operation ox the dispensing arrangement including the valve and ¢ontalner should be evident. It can be made essentially Or all plastic parts which are easily molded. Other materials can, of course be used.
For example, the bottle 238 may be made of glass or metal. By forming the dispensing valve in one piece with the manifold and through the design of a manifold which essentially carries the supply ox materials to the valve, the need or numerous tubes and the dlsadvant goes associated therewith are avoided. The design ox the valving in the container permits presetting at the factory, with the adjustment screw on the manifold giving the fine Pd~ustment necessary to take care ox .

-Jo-temperature variations or personal taste. Furthermore, it is important I note, when referring to Fig. 20, that the concentrate passes directly from the container into the cup. It has been well established, what mold growth is likely to occur with dilute syrup. With the disk closed dispensing arrangement the syrup is diluted only after leaving the dispenser This offers great advantage over most prior art dispensers in which mixing took place within the machine and which could lead Jo unsent-try conditions.
An alternate embodiment or the dispenslngvalve is illustrated in Fig. 22. In Rome cases it may be desired to have the dispensing unit at a wink. In such a case 3 the remainder ox the above described apparatus would be disposed below the slunk In such a case, the valve would of course, not be part ox the manifold OWE Rather referring for example, to Fig. 16, the lines 103 and 117 would be brought out prom the manifold through suitable tubing to inlets at the valve 2Q itself. A valve 76C is disposed on the end of an angled arm 502 with a container 81 placed thereon. The arm is supported for rotation over a sink 504. For example, the opening in the wink normally used for a spray attachment could be used. When not in use the arm ~02 may be rotated counterclockwise to move the dispenser out ox the way where it is locked in detents When it Is desired to dispense the arm 502 it moved to the position .. .. .. ... , ..,, , ., , . . ..,,, , , , . , ,, , , '- :

shown and dispensing can be carried over the sink so that any spillage or drip will be caught in the sink. Preferably; the arm 502 and at least the visible parts Or the valve 76C in this case will be made ox a material to match the sink fittings. Operation of the valve 76C in con~unctlon with the container 81 in all other respects will be the same as described above Figs. 23-29c illustrate Rome possible mud-cations ox the present invention with respect to the valving action. In these embodiments, operation in all other respects than discussed will ye the same as previously described. Only the parts of the valving mechanism which are different will be discussed in detail.
Fig. 23 illustrates a particularly simple embodiment Or the invention, Shown is a bottle 505 with tabs 507 thereon for insertion in a rotary valve, or the type previously described in connection with Figs. 15 and 16 for example On the end ox the neck ox the bottle, which terminates in a planar annular portion 509, is a snapped cap 511 with a tab 513 adapted to insert in a slot in a rotatable valve member of the type described above. The cup is shown as having a dip tube 514 extending therefrom to permit the introduction ox the pressurizing gas in the manner described above. Cap 511 has a hole or opening 519 there through which worms the dispensing outlet The annular surface ox the mottle also conchs a hole 521 better seen on Flog 24 As is evident from an examination of Flog 24 rotation the tab ~13 in the direction of arrow 523 through a predetermined angle will result in the alignment ox the holes 519 and 521 to bring about dispensing. control of the amount dispensed can be brought about by controlling the size of the opening 521 and/or preferably by the overlap Or the openings 521 and 519.
Fig. 25 illustrates a further embodiment of the present invention employing a bottle 505. On the end thereon is a cap 611 quite similar to the cap 511 shown on Fig. 23. The cap however contains a semi-cylindrical projecting portion 613 along one side thereon. This worms a channel 615 which constitutes the I dispensing ovately. extending through the wall ox the cap and leading into the channel 615 is an opening 617.
The neck ox the bottle 605 also contains an opening 619.
Movement of the cap in the darken of the arrow 621 results in alignment ox the two holes to permit the con-I cent rate to be dispensed through the openings Sly and 617 and the channel 615~ A key 622 on bottle 605 inserts in a kiwi 623 on cap 611 to prevent rotation.
Alternatively a lug on the neck ox bottle 605 can run in an extension of channel 615.
Fig. 27 illustrates an embodiment in which a bottle 705 has a conventional thread 707 on it neck.
Screwed onto the thread ?07 is a cap 709~ of the same . .

general type described in connection with jigs. 15 to 21, the primary difference being that the cap and neck contain matching threads rather than cooperating nibs and slots. In all other respects the construction ox the bottle and cap will be essentially the same. In other words an insert in the bottle neck will be provided and the cap will have a projecting portion cooperating with the insert to form a valve. As previously described, an opening is wormed into the cap to permit the dispensing ox the liquid. The bottle 705 possess tabs 711 and is inserted into appropriately shaped slot 715 in a ire part of the rotary valve mechanism.
Similarly, as in the previously discussed embodiments, the cap 709 contains a tab 713. this slides into a slot 715 in the rotatable valve part. However slot 715, unlike the slots in the previous embodiment permits movement of the rotary alluvia part aye with respect to the cap 709 between positions corresponding to the positions of Figs. aye and lob. This is accomplished by worming the slot 715 so as to have a vertical portion 717 to allow insertion of the cap of the bottle and a horizontal portion 719. A further vertical portion 721 is provided or a reason to be described below. Thus initial rotation of the rotating part aye will result in no movement ox the cap. The tab 713 will slide in the horizontal portion ox the slot 719. Position corresponding to those ox Figs. aye and 15b are shown by .

Fig. aye and 29b. In the view ox Fig. aye the tab 713 is at the bottom Or the vertical slot 717. During the lust part ox the motion, the tab slides in the slot 719 until it comes into abutment with the edge 723. This corresponds to the position ox Fig. 15b. Now, further notation of the rotating part aye will carry the tab 713 with it and will begin to unscrew the cap 709 prom the bottle neck to open the valve in the manner described above. This is indicated by the position shown in Fig.
29c. When this occurs, as the cap is unscrewed it will move downward, and the tab will move downward into the vertical portion 721. Now, when it is desired to return the valve to the closed position, the surface 725 will act against the other side of the tab 713 to screw the cap 709 back onto the neck ox the bottle 705, by means of the threads 707~ to close the valve. Further rotation will disengage tab 713 from slot 721 and allow it to slide on slot OWE In this embodiment, and in the other embodiments it is possible to Norm the necessary 810ts in the cap or bottle respect-lively and to dispose and to place the necessary tabs on the valve parts. It will be recognized that equivalent operation will be obtained.
Flannel in the various embodiment, it is generally indicated that dispensing is accomplished by rotating a handle such as the handle 191 ox Figs. aye-I, -, .

15c. In many instances 7 it might be desired to simply press a glass, into which dispensing is to take place, against an actuator such as is common in water dispensing apparatus in restaurants. The present invention can ye adapted to such simply by providing conventional means for converting motion of this nature into the rotary motion needed to rotate the rotating part of 189 of the valve or the vertical motion required by the embodiments shown in Figs. 25 and 26. It is believed that such linkages are well within the scope of those skilled in the art and will not be described in detail herein.
Modification of the nature just described and other modifica~
lions can be made without departing from the spirit of the present inventive.
Fig. 30 shows an improved form of valve and manifold according to the present invention. The arrangement is essentially the same as that shown in Fig. 15. The embodiment of Fig. 309 however, is adapted for easier molding and is also adapted to be used with an improved form of valving mechanism in the container. Manifold aye contains appropriate bores aye to receive the rotating valve members aye. As in the previous embodiment, an inlet opening 105 for the delineate surrounded by an 0 ring seal 109 and an inlet opening 119 for the carbon dioxide surrounded by an 0 ring seal 123 are provided. The passages to ding to the outlets 105 and aye, portion ox the passage 115 a being visible in Fig. 30 are molded into the manifold 77 such that they are of U shaped cross section. They are when enclosed by an appropriate cover piece which it bonded into place. The same scheme is is utilized in forming passages aye and aye in the central rotating valve member aye as will be seen below. A central opening aye through which the spout aye extends for dispense in delineate and also from which the concentrate can be dispensed is provided as in the previous embodiments. Also included is a drainage slot aye performing the same function as the drainage slot 187 of Fig. 15. As can be seen Prom Fig. 30 and Figs. 31 and 32, the rotating valve member is molded to be cup-like with an outer cylindrical wall 190 which rotates within the opening aye. Concentric therewith is an inner all 192 which forms the opening in which the cap of the container is inserted, as best seen in Fig. 31. Inner wall 192 contains a slot aye therein in which the tab aye on a cap aye is inserted. As previously explained, as the central rotatable member is rotated by means of a handle aye, the cap will rotate therewith. Disposed over the base aye and the rotate able central valve members aye, and retaining them in place is a cover aye having slots 21~ to permit the handles aye to extend there through. The cover contains a central opening in which diametrically opposed slots aye are wormed to engage tabs on the neck of the container. These take the place of the similar slots 217 in the adjustment disc so Fig. I In the present embodiment, adjustment by means ox an adjustment disc is not carried out. Rather, all adjustment Jo take care of temperature variations or the like can be done by control-in pressure or by using temperature sensitive mean in the outlet passage within the central valve member aye between the walls 190 and 192r the expansion chamber aye, for the delineate is formed by two curved walls 236 and 238 respectively.
This chamber communicates with the spout aye. The inlet to the chamber is through an inlet opening 235b best seen on the bottom plan view of Fig. 32. When in the proper position, this over-lies the delineate outlet 105. The wall 236, along with a wall 240 form the carbon dioxide chamber or passage aye. Carbon dioxide from the outlet 119 enters through an inlet opening 225c and flows from the chamber aye into a chamber 225b which is formed in a strut aye which extends from the wall 192. This terminates in a central cylindrical member aye which is adapted to be inserted into the central opening in the cap. An additional solid strut 223b helps Support the member aye.
Member aye is surrounded by an 0 ring seal aye. In order to fully enclose the chambers aye and aye, a cover 194 is provided which is welded in place onto the rotatable valve member aye so as to seal against walls 190 and 192 along with partitions 236, 238, and 240.
Biasing of rotatable valve member aye is by means of a spring aye and a suitable post 232 on the base aye. This biases the handle to the left as seen in Fig. 30 so that neither opening 225c nor 235b are overlying their respective outlets 119 and 1~5. In this embodiment, there is no vent position. Rota-lion of the handle aye to the right results in the opening 225c first coming to overlie the slotted opening 119; thereafter, with continued rotation, the opening 235b will overlie the outlet 105. In the present embodiment the container, when removed from the machine, remains pressurized. Thus, venting is not required.

Other than the lack of venting, and the lack of an adjustment disc, the embodiment of Fig. 30 is functionally identical to that of Fig. 15. The changes are made simply to facilitate molding of the parts and to avoid the need to carry out machining. The channel 225b is closed off by a cover member 225d shown in Fig. 31 but not in place in Fig. 32. In this way, the major portion of the central valve number aye can be molded thereafter the cover 194 can be put in place along with the cover or insert 225d, both sealed in place so as to provide the necessary chambers. Similar techniques are used in molding the manifold aye so as to form various needed passages such as the passage aye.
Figs. 31 and 32 also show a preferred valving arrange-mint for the container. In the embodiment previously disclosed, the rate of concentrate dispensing was controlled by the amount of rotation. In the embodiment of Figs. 31 and 32, the basic control of the amount of concentrate being dispensed is by means of the size of the opening aye through the cap. This will be sized according to the type of concentrate being dispensed. For example, diet soda concentrate is much less viscous than syrups containing sugar. Thus or diet concentrates the diameter of the bore opening aye will be much smaller. Furthermore, various types of check valves, which were previously tried failed to adequately seal against leakage of a diet concentrate.

For this reason, the embodiment of Fig. 31 uses a positive shutoff valve rather than a check valve. As before, the cap is formed with a central bore into which the gas outlet aye it inserted and sealed by means of the O ring Neal aye. This go opening communicates with a tube aye. In the previous embody-mint, this was a dip tube which contained in it a check valve.
In the resent embodiment t this tube, which has a flat end, seals against a cylindrically shaped seal member 242 preferably made of food grade silicone rubber. The cap can be made of polypropylene or low density polyethylene as may the plug aye which is inserted into the neck of the container aye. The cylindrical plug 242 is retained in a projecting portion of the plug made of four equally spaced ribs AYE. The ribs extend from an annular surface 244. Annular surface 244 seats against an 0 ring aye retained in a slot in the cap. This prevents any of the concentrate, which will be surrounding the ribs Allah prom getting past this sealing point. In addition, a further 0 ring seal 246 prevents leakage from the joint between the insert aye and the bottle aye.
In operation, as previously, rotation of the cap aye, which contains slots aye in which tabs aye on the bottle 238 are inserted, the slots aye being slanted as shown in Fig. AYE, results in the movement ox the cap aye with respect to the insert aye. This simultaneously causes the tube aye to separate from the cylindrical seal 242 to permit pressurizing was to reach the interior of the container, and moves the annular part 244 away from the O ring Neal aye. As a result 9 slow ox the concentrate can reach the outlet aye To prevent concentrate prom escaping from below that point an additional 0 ring seal guy is provided between Curses of the insert aye and the inner portion of the cap aye. As these two surfaces move with respect to each other, the 0 ring seal maintains a .. .. - .

In this embodiment, when the container is first used 9 there Jill not be an elevated pressure in the container until the cap is first rotated to open the valve order button the tube aye and the member 242. However at the tame time as pressurizing tales place dispensing will commence phonies a passage Jo the occult aye t ill be opened. This of course only occurs on the first drink .
