Definitions

  • This invention relates in general to the dispensing of beverages and more particularly to a package for use in a beverage dispenser and the combination of such a package and a beverage dispenser.
  • carbonated beverages which are consumed in the home are supplied to the consumer in either cans or bottles.
  • cans are supplied in 12 ounce (0.35 I) sizes and bottles in sizes up to two litres.
  • a carbonated beverage is made up of carbonated water to which there is mixed a juice or syrup.
  • a good tasting beverage requires good water, the proper level of carbonation and the proper proportions between the syrup and carbonated water.
  • the equipment used includes a carbonator for carbonating the water, a concentrate, i.e., a juice or syrup, a dispenser for dispensing the concentrate in the proper quantities and mixing it with the carbonated water, and a filling device for filling it into the bottles.
  • a chiller unit for chilling the water to be carbonated. Carbonation is carried out by bringing carbon dioxide and water into contact with each other in such a manner that the carbon dioxide dissolves into the water. Typically the water is over carbonated since in the step of dispensing into the bottles or cans, a certain amount is lost.
  • Systems can be operated in which the water and syrup are mixed prior to or after carbonation.
  • carbonated beverages are also dispensed at restaurants, and at soda fountains and the like.
  • the devices used for such dispensing are known as post mix dispensers, and include the same basic elements as one finds in a carbonation plant. In other words, they include means for chilling the water, carbonating equipment for carbonating the water, a juice or syrup dispenser for dispensing metered amounts of concentrate and a tap for dispensing the mixture of concentrate and water into a glass or cup. Typically, mixing of the concentrate and water is carried out at the tap.
  • the present invention relates to a system in which the concentrate for the dispenser is supplied in packages so that users, instead of carrying bottles and cans of carbonated beverage from stores to their homes, can simply carry the packages of concentrate, which on a volume for volume basis will provide many more drinks than bottles or cans containing the same volume of carbonated beverage. The consumer therefore does not have to transport large quantities of water from store to home, which of course is a considerable saving. As alluded to above many factors influence the creation of an efficient in-home dispensing system and the packages therefore.
  • these factors include, but are not limited to, the size of the dispenser, the cost of producing a drink from the dispenser, as compared with the cost of buying the equivalent drink from a supermarket or drug store, the number of flavours of drink which can be dispensed from the machine, the ease with which concentrate packages can be removed and replaced, the prevention of leakage and dripping of concentrate, the ability to dispense the beverage in a continuous manner, the designing of the system so that certain sanitary conditions are met, and the keeping to a minimum cleaning of the device to keep it in a sanitary condition.
  • the present invention provides a system for in-home drinks dispensing which, it is believed, either overcomes, or goes a long way to overcoming, all of the aforesaid difficulties.
  • the system firstly provides a package for the concentrate to be used in the dispenser, and secondly the combination of dispenser and the said package.
  • a general object of the present invention is to provide an economical, efficient dispensing system (packages and package/dispenser combination), for beverages which are made by mixing a diluent with a concentrate, in particular for carbonated beverages. Furthermore, by the use of such packages and combination dispensing any of a plurality of different carbonated beverages such as cola, diet cola, quinine water, orange, rootbeer, etc., in an efficient manner, should be possible. In addition, such a system should also be adaptable to dispensing still beverages such as fruit drinks or juices, and hot in addition to cold beverages. Although reference has been made herein to in-home use of the system the system and packages according to the invention can be used anywhere, where post mix dispensing of beverages is required, such as in restaurants, bars, soda fountains, etc.
  • a package for use in a beverage dispenser comprising:
  • the package of the invention therefore provides an excellent means of distributing concentrate for beverages. If the diluent is water, then if a person has a suitable dispenser, and a supply of water at its place of use it is not necessary to transport large quantities of water as between the store or supermarket and the places of use of the concentrate, typically in a domestic dwelling.
  • the package is preferably designed so that no concentrate will flow or drip therefrom when the package is lifted from the dispenser, and to this end, the means whereby the fluid communication can be established may comprise a flexible split seal, acting as a one-way valve, which is opened only when the package is in place on the dispenser by means of a suitable projecting member of the dispenser, and closed automatically when the container is removed from the dispenser.
  • the package By providing the outlet aperture in the cap, the package can be arranged so that the concentrate which flows therefrom is caught directly in the vessel from which the beverage is consumed, which represents a considerable advantage, as there will be no dilute beverage in contact with the dispenser, and the need for cleaning of the dispenser will be much reduced.
  • the invention also provides the combination of a package as aforesaid and a dispenser and in accordance with this aspect of the invention there is provided the combination of a dispenser for dispensing beverages and a disposable package as aforesaid, the said dispenser comprising a holder for holding the said package in inverted condition, a movable component of said holder for displacing the cap relative to the body, to cause flow of concentrate therefrom whereby the concentrate is disposed into space and can be caught in a drinking vessel.
  • the total unit is disposed on a base and is enclosed by a plastic cover designed to allow easy heat evacuation. It is particularly compact, attractive, sanitary and inexpensive.
  • the combination of the present invention is disclosed primarily as a unit for dispensing carbonated beverages and also as an in-home dispensing unit, it is not limited to such functions. Obviously, as will become evident, the combination, with appropriate modification, can also be used in restaurants, soda fountains and the like. Furthermore, in addition to dispensing carbonated beverages in which carbonated water is mixed with a concentrate such as a flavouring syrup, quinine concentrate or the like, the combination of the present invention may also be used for dispensing still beverages and for dispensing hot beverages. In other words, it is generally adaptable to dispensing any beverage in which a concentrate is mixed with a diluent. The diluent need not be still water or carbonated water although in most cases it will.
  • the concentrate need not touch any part of the dispensing apparatus. What this means is that dilute concentrate which, particularly when it is something like syrup, can result in the growth of mold, never contacts the dispenser. This maintains sanitary conditions.
  • the container is particularly adapted to filling in a near sterile condition which may be of particular importance with respect to some types of hot and still drinks.
  • a pressurising gas which could be an inert gas such as nitrogen where carbonation is desired, the gas may be used to maintain near sterile conditions and to maintain flavour integrity in the apparatus over periods of time.
  • this pressurized gas would, of course, also pressurize the water supply.
  • the various features of the present invention which give it its simplicity and compactness will be of advantage in dispensing other types of beverages, i.e., still cold and hot beverages, in addition to cold carbonated beverages.
  • the present invention will be described in detail in connection with an in-home beverage dispenser particularly adapted for carbonated beverages.
  • the various aspects of the present invention are also useful in other environments, such as in restaurants, soda fountains, etc.
  • the package dispenser combination of the present invention can also be used for making still drinks, for example, for mixing a fruit juice concentrate with water to make a juice, and also for making hot drinks by mixing hot water with a suitable concentrate.
  • Fig. 1 is a generalized block diagram of a system which uses packages according to the present invention.
  • the system includes a water source 11.
  • this is a source of diluent which is later mixed with a concentrate. Although it will, in most cases, be water, other diluents might be used.
  • Shown in connection with the water source is an inlet 13.
  • the inlet 13 may be an inlet which is plumbed into the plumbing of the location where the dispenser is used or may simply be an opening in the water tank which permits refilling.
  • the water from the water source is shown passing through a heat exchanger 15. Shown associated with the heat exchanger 15 is a cooling unit 17 and a heating unit 18.
  • Cooling can be supplied to the heat exchanger 15 by opening a valve 19 and heating or cooling will be associated directly with the water source or water tank 11.
  • the heat exchanger 15 and associated cooling 17 and heating 18 simply comprise means for adjusting the temperature of the diluent.
  • a carbonator 23 At the outlet of the heat exchanger 15 is a carbonator 23.
  • Carbonator 23 is supplied with carbon dioxide from a tank 25 through a reducing valve 26, a line 27 and, a manifold 29. When the carbonator is in use, carbonated water is supplied over line 33 to the manifold 29.
  • the manifold 29 supplies this water or other diluent to dispensing valves 35 and 36 in accordance with the present invention.
  • Still water is applied over a line 34 to a mixing valve 31 which has a second inlet supplied with carbonated water from line 33 and permits supplying to dispensing valve 36 any desired proportions or mixture of still and/or carbonated water.
  • packages 37 filled with a concentrate which is to be mixed with the diluent.
  • the metering valve for concentrate is in the container 37 and is coupled to and cooperates with the dispensing valves 35 and 36. That is, the package 37 with the concentrate includes valving means to meter the amount of concentrate in response to a relative movement of two parts of the package brought about by the dispensing valve 35 or 36.
  • the supply of carbon dioxide over line 27 is also used to pressurize the concentrate in the packages 37 after being coupled through a reducing valve 39. Also shown is a line 40 coupling carbon dioxide to water source 11 to supply the diluent at a constant pressure.
  • the carbonator may also be built into the water container as is the case in the embodiment to now be described. In that case, water source 11 is also the carbonator.
  • carbon dioxide is shown as the pressurizing gas, in embodiments where carbonation is not desired, it may be replaced by any inert gas such as nitrogen.
  • the embodiment of the dispenser illustrated in perspective view of Figs. 2a and 2b includes a supporting structure 41 which is preferably of molded plastic.
  • Structure 41 includes a base 43 and an upstanding T-shaped portion 45.

  • Reducing valve 69 reduces the carbon dioxide pressure to .275 N/m 2 C0 2 at this pressure is fed through a passage 91 in the manifold 77 to the disconnect coupling 89. From that point it flows through tubing 90 to a restrictor 93, and thence to a diffuser 95. Carbonated water is removed from the carbonator tank through a line 97 extending to the bottom of tank 61 and leading to the coupling 89 whence it enters a passage 99 in the manifold. This passage connects with two smaller passages 101 and 103, which lead to outlets 105 and 107, in the portion of the valves which is integral with the manifold. At each of the outlets an 0-ring seal 109 is provided.

Rotation while the nibs are in the horizontal area 275 of the 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 of central valve member 189 shown in Fig. 6a and 6b.

It will be arranged that the nibs 271 will be in a position in the said straight portions 275 intermediate the ends thereof when the package is in the dispenser and the rotary valve is in the position shown in Fig. 6a to enable ring 193 to be adjusted in both directions but that movement of the rotary valve to the Fig. 6b position will not cause the nibs 271 to ride up the angled portion 277. Also, the angled portions 277 should be of sufficient length that the nibs lie between the ends of the angled portions 277 when the dispenser is in the Fig. 6c position, again to permit the adjustment of said ring 193.
  • Fig. 10a Also shown in cross section on Fig. 10a is the worm gear 198 of the adjustment screw 195 of Figs. 4 and 6. It is evident, that the dispensing action, i.e., the opening of the valve in the package takes place because of a relative movement between the cap 230 and the body 238. During normal operation, the body 238 is held fixed because of the insertion of the tabs 211 in the slots 217 in the adjustment ring 193.

  • the nibs 271 will be positioned, as explained herein, during manufacture so that when the package is inserted in the valve, movement of the member 189 between the Figs. 6a and 6c position, will give the desired amount of valve opening based on the viscosity of the concentrate and on a standard ambient temperature, e.g., 20°C, without any adjustment of the adjustment screw 195. However, if the drink dispenser is operated under ambient conditions where a higher or lower temperature exists, this will affect the flow rate for a given opening of the valve.
  • the adjustment 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 body 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 277 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 said slots 277 must, as explained herein, be of sufficient length.

  • the packages are preferably designed to be of the throw-away variety, and to this end the components thereof are preferably constructed from plastics material.
  • Figs. 19-25c illustrate some possible modifications of the present invention with respect to the valving action. In these embodiments, operation in all other respects than discussed will be the same as previously described. Only the parts of the valving mechanism which are different will be discussed in detail.
  • Fig. 19 illustrates a particularly simple embodiment of the invention. Shown is a package with a body e 505 with tabs 507 thereon for insertion in a rotary valve, of the type previously described in connection with Fig. 4 for example. On the end of the neck of the body, which terminates in a planar annular portion 509, is snapped a cap 511 with a tab 513 adapted to insert in a slot in a rotatable valve member of the type described above.
  • the cap is shown as having a dip tube 514 extending therefrom to permit the introduction of the pressurizing gas in the manner described above.
  • Cap 511 has a hole or opening 519 therethrough which forms the dispensing outlet.
  • the annular surface of the body also contains a hole 521 better seen in Fig. 20.
  • a hole 521 better seen in Fig. 20.
  • rotation of the tab 513 in the direction of arrow 523 through a predetermined angle will result in the alignment of 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 of the openings 521 and 519.
  • Fig. 21 illustrates a further embodiment of the present invention employing a package with a body 605.
  • a cap 611 On the end thereof is a cap 611 quite similar to the cap 511 shown in Fig. 19.
  • the cap contains a semi-cylindrical projecting portion 613 along one side thereof. This forms a channel 615 which constitutes the dispensing outlet. Extending through the wall of the cap and leading into the channel 615 is an opening 617.
  • the neck of the body 605 also contains an opening 619. Movement of the cap in the direction of the arrow 621 results in alignment of the two holes to permit the concentrate to be dispensed through the openings 619 and 617 and the channel 615.
  • a key 622 on bottle 605 inserts in a keyway 623 on cap 611 to prevent rotation.
  • Fig. 23 illustrates an embodiment in which a package body 705 has a conventional thread 707 on its neck. Screwed onto the thread 707 is a cap 709, of the same general type described in connection with Figs. 8 to 10, the primary difference being that the cap and neck contain matching threads rather than cooperating nibs and slots.
  • the construction of the body and cap will be essentially the same.
  • an insert in the body neck will be provided and the cap will have a projecting portion cooperating with the insert to form a valve.
  • an opening is formed into the cap to permit the dispensing of the liquid.
  • the body 705 possesses tabs 711 and is inserted into appropriately shaped slots 714 in a fixed part of the rotary valve mechanism.
  • the cap 709 contains a tab 713.
  • This slides into a slot 715 in the rotatable valve member 189a.
  • slot 715 unlike the slots in the previous embodiment, permits movement of the rotary valve member 189a with respect to the cap 709 between positions corresponding to the positions of Figs. 6a and 6b. This is accomplished by forming the slot 715 so as to have a vertical portion 717 to allow insertion of the cap of the package and a horizontal portion 719. A further vertical portion 721 is provided for a reason to be described below.
  • initial rotation of the rotating valve member 189a will result in no movement of the cap.
  • the tab 713 will slide in the horizontal portion of the slot 719.
  • Figs. 25a and 25b Positions corresponding to those of Figs. 6a and 6b are shown by Figs. 25a and 25b.
  • the tab 713 is at the bottom of the vertical slot 717.
  • the tab slides in the slot 719 until it comes into abutment with the edge 723. This corresponds to the position of Fig. 6b.
  • further rotation of the rotating part 189a will carry the tab 713 with it and will begin to unscrew the cap 709 from the body neck to open the valve in the manner described above. This is indicated by the position shown in Fig. 26c. When this occurs, as the cap is unscrewed it will move downward, and the tab will move downward into the vertical portion 721.
  • dispensing is accomplished by rotating a handle such as the handle 191 of Figs. 6a-6c.
  • a handle such as the handle 191 of Figs. 6a-6c.
  • an actuator such as is common in water dispensing apparatus in restaurants.
  • the present invention can be adapted to such simply by providing conventional . means for converting motion of this nature into the rotary motion needed to rotate the rotating valve member 189 of the valve. 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. Modifications of the nature just described and other modifications can be made without departing from the spirit of the present invention.
  • each embodiment there is control of the degree of opening of the package valve.
  • Control of the degree of opening the valve is necessary for a number of reasons.
  • different concentrates will have different viscosities.
  • diluent at a predetermined constant rate and where, to get a properly flavoured drink, a certain amount of concentrate must be mixed with that diluent
  • different degrees of openings will be necessary in order to accommodate the different flow characteristics of different concentrates due to their different viscosities, that flow being under essentially constant pressure.
  • changes in environmental conditions, particularly temperature can effect the viscosity and may require further adjustment.
  • the last two types of adjustments mentioned are adjustments which must be done at the dispenser.
  • the first type of adjustment i.e., adjustment to take into account different viscosities can be accomplished either through proper dimensioning of the package parts or through a combination of dimensioning of the package parts and an adjustment in the dispensing valve in the dispenser with which the package is used Providing such control by means of dimensioning at the package is thought to be preferable. This is because it requires no further adjustment by the user other than to accommodate that variation.
  • the dispensing valve with which the package cooperates can then be constructed so as to bring about a pre-established 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.
  • these means for effecting the movement will be so constructed and dimensioned that for this pre-established amount of movement the separation of the two valve parts will give the desired degree of opening forthe particular concentrate contained within the package.
  • the packages may well be dimensioned identically and the dispensing valve with which it cooperates made adjustable in order to allow different amounts of 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, simplify manufacture of the packages since all could be identical.
  • the means for introducing an essentially constant head pressure include means for introducing ambient air at a constant head pressure
  • the preferred embodiment is one in which dispensing takes place under the pressure of a pressurizing gas.
  • means be provided for supplying the pressurizing gas to the package after it has been inserted into the dispensing valve of the dispenser.
  • pressurizing takes place under control of the same valve which controls the dispensing operation.
  • This valve which as previously indicated, cooperates with the means for effecting movement of the first and second parts, in the case of a pressurizing gas, of necessity, includes a first position where the pressurizing gas supply is cut off, a second position where the pressurizing gas supply is available, and the dispensing valve has acted on the means for effecting movement of the first and second parts with respect to each other to open the valve in the package and is at the same time opening a passage for the supply of diluent to be mixed with the concentrate in the package.
  • the dispensing valve 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, i.e., shut off, permitting insertion and removal of the package, and the second position, where the pressurizing gas is pressurizing the concentrate but dispensing has not yet taken place, 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 disclosed in which such is accomplished within the dispensing valve.
  • the first and second valve parts can take any one of a number of different forms.
  • 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 communication with the volume of concentrate in the container and the other opening in communication with the outlet.
  • the degree of overlap of two openings and/or the size of the smaller of the two openings will determine the flow rate of concentrate.
  • the opening in the second valve part which contains the outlet could be made relatively large and the opening in the other package part could be made of a size to meter the desired amount of concentrate.
  • Movement of the two openings into alignment with each other, in response to a preset degree of movement of the two package parts with respect to each other, would thus result in metering the desired amount of concentrate.
  • the disadvantage of an embodiment of this nature is that it does not easily permit additional control to take into account temperature variations or the taste of the user.
  • Fig. 26 An alternative embodiment for the dispenser is illustrated in Fig. 26.
  • the dispensing valve at a sink.
  • the remainder of the above described dispenser would be disposed below the sink.
  • the valve would, of course, not be part of the manifold 73.
  • the lines 113 and 99 would be brought out from the manifold through suitable fittings 104 and 118 similarto fittings 129 and 131, described above, containing check valves.
  • a quick disconnect coupling such as the coupling 89 may mate to these fittings with tubing extending from the coupling to inlets at the rotary valve 76c.
  • Valve 76C is disposed on the end of an angled arm 502 with a package 81 placed thereon.
  • the arm is supported for rotation above a sink 504.
  • the opening in the sink normally used for a spray attachment can be used.
  • the arm 502 may be rotated counterclockwise to move the dispensing valve and package out of the way into a locked position.
  • the arm 502 is moved to the position shown and dispensing will take place over the sink so that any spillage or drips will be caught in the sink.
  • the arm 502 and at least the visible parts of the valve 76C in this case will be made of a material to match the sink fittings. Operation of the valve 76C in conjunction with the package 81 in all other respects will be the same as described above.
  • the rate of flow of the diluent can be controlled either by dimensioning of the size of the diluent tubing or passages e.g., passages 103, or by the insertion of a limiting orifice, for example, at the inner end of the stub 131.
