Title: Beverage dispensing system

Description:
RELATED APPLICATIONS 
     This application is a continuation of U.S. Ser. No. 11/276,550, filed on Mar. 6, 2006, now pending. U.S. Ser. No. 11/276,550 is incorporated herein by reference in full. 
    
    
     TECHNICAL FIELD 
     The present application relates generally to beverage dispensing systems and more particularly relates to a beverage dispenser for providing a number of different beverage alternatives. 
     BACKGROUND OF THE INVENTION 
     Commonly owned U.S. Pat. No. 4,753,370 concerns a “Tri-Mix Sugar-Based Dispensing System.” This patent describes a beverage dispensing system that separates the highly concentrated flavoring from the sweetener and the diluent. This separation allows for the creation of numerous beverage options using several flavor modules and one universal sweetener. One of the objectives of the patent is to allow the beverage dispenser to provide as many beverages as may be available on the market in pre-packaged bottles or cans. U.S. Pat. No. 4,753,370 is incorporated herein by reference. 
     These separation techniques have continued to be refined and improved. As is shown in commonly owned U.S. patent application Ser. No. 11/276,553, entitled “Methods and Apparatuses for Making Compositions Comprising an Acid and an Acid Degradable Component and/or Compositions Comprising a Plurality of Selectable Components”, the acid and non-acid components of the non-sweetened concentrate also may be separated. This separation allows for a prolonged shelf life and also enables further concentration of the flavor components. U.S. patent application Ser. No. 11/276,553 is incorporated herein by reference. 
     Beverage dispensers historically have worked by combining a diluent (such as water) with a beverage base. These beverage bases usually have a reconstitution ratio of about 3:1 to 6:1. The beverage bases usually come in large containers that require large amounts of storage space and may need to be refrigerated. Theses requirements often necessitate the need to store these containers far from the actual dispenser and to run long lines from the containers to the dispenser. 
     Given the improvements in shelf life and concentration described above, there is a desire for a beverage dispenser that can produce even more and different types of beverages while using a smaller footprint. This can be accomplished by breaking down the traditional beverage bases into constituent parts at much higher reconstitution ratios. These parts can then be stored in much smaller packages and stored closer to, adjacent to, or within the beverage dispenser itself. The beverage dispenser preferably can give the consumer multiple beverage options such that the consumer has the ability to customize his or her beverage as desired. 
     SUMMARY OF THE INVENTION 
     The present application thus describes a product dispenser. The product dispenser may include at least one macro-ingredient source, at least one micro-ingredient source positioned about the dispenser, a diluent source, a dispensing valve, a number of pumps or metering devices, and a user interface. The user interface receives a request for a product type and instructs the pumps or metering devices to dispense a predetermined type and ratio of macro-ingredients, micro-ingredients, and diluent to the dispensing valve for a predetermined flow rate. 
     The user interface may include a control device. The control device instructs the number of pumps or metering devices to dispense a predetermined type and ratio of macro-ingredients, micro-ingredients, and diluent to the dispensing valve for the predetermined flow rate. 
     The macro-ingredient source may include a macro-ingredient with a reconstitution ratio of about 3:1 to about 6:1. The macro-ingredient source may include sugar syrups, HFCS (High Fructose Corn Syrup), and juice concentrates. The micro-ingredient source may include a micro-ingredient with a reconstitution ratio of about 10:1 or higher. The micro-ingredient source may include natural and artificial flavors, natural and artificial colors, artificial sweeteners, vitamins, minerals, herbal extracts, nutraceuticals, pharmaceuticals, and acid and non-acid components of flavoring. 
     The diluent source and the macro-ingredient source each may be in communication with one of the pumps. The micro-ingredient source may be in communication with one of the metering devices. The pumps or metering devices may include a positive displacement pump. 
     The dispensing valve may include a multi-flavor valve. The dispensing valve may include a flow director in communication with the macro-ingredient source and the diluent source. The dispensing valve may include a tertiary flow assembly in communication with the micro-ingredient source. 
     The user interface may include a number of product selections, a number of additive selections, a number of intensity selections, nutritional information, and a consumer data system. The consumer data system may include one or more biometric sensors. The product type may be a custom product or a branded product. 
     The present application further describes a mixer for producing a number of product types. The mixer may include a number of ingredient sources positioned about the mixer with ingredients having reconstitution ratios higher than about ten to one, a diluent source, a number of pumps or metering devices, and a user interface. The user interface receives a request for one of the product types and instructs the pumps or metering devices to dispense a predetermined type and ratio of ingredients and diluent for a predetermined flow rate. 
     The present application further describes a beverage dispenser for producing a plurality of beverages. The beverage dispenser may include a number of ingredient sources positioned about the dispenser having ingredients with reconstitution ratios higher than about ten to one, a diluent source, and a number of pumps or metering devices in communication with the ingredient sources and the diluent source. 
     The present application further describes a product dispenser. The product dispenser may include at least one macro-ingredient source, at least one micro-ingredient source positioned about the dispenser, a diluent source, a dispensing valve, a number of pumps or metering devices, and a user interface. The user interface receives a request for a branded beverage and instructs the pumps or metering devices to dispense a predetermined type and ratio of macro-ingredients, micro-ingredients, and diluent to the dispensing valve. 
     These and other features of the present application will become apparent to one of ordinary skill in the art upon review of the following detailed description of the invention when taken in conjunction with the several drawings and the appended claims. 
    
    
     
       BRIEF DESCRIPTION OF THE DRAWINGS 
         FIG. 1  is a schematic view of a beverage dispenser as is described herein. 
         FIG. 2  is a perspective view of a dispensing nozzle assembly that may be used with the beverage dispenser of  FIG. 1 .

     DETAILED DESCRIPTION 
     Referring now to the drawings, in which like numerals indicate like elements throughout the several views,  FIG. 1  shows a beverage dispenser  100  as is described herein. A user interface  110  may control all of the functional aspects of the beverage dispenser  100 . A consumer may select and/or create numerous types of beverages, blends, and additives using the user interface  110 . A control device  120  may support the user interface  110 . The control device  120  may be a conventional microcomputer or a similar type of device. The control device  120  may be internal to or remote from the beverage dispenser  100 . 
     The beverage dispenser  100  may use any number of different ingredients. In this example, several different types of ingredients may be used: water (plain and/or carbonated) from a water source  130 ; macro-ingredients from a number of macro-ingredient sources  140 ; and micro-ingredients from a number of micro-ingredient sources  150 . Any number or combinations of sources  130 ,  140 ,  150  may be used herein. For example, it may not be necessary to have a macro-ingredient source, e.g., HFCS, which is difficult to pump at high reconstitution ratios, may not be used. As such, only a diluent and a micro-ingredient source may be required. 
     The water from the water source  130  may or may not be refrigerated. Other types of diluents may be used herein. A conventional carbonator or a similar type of device may be used to produce carbonated water as desired. The amount of carbonation may be varied. 
     Generally described, the macro-ingredients may have reconstitution ratios in the range of about 3:1 to about 6:1. The viscosities of the macro-ingredients typically range from about 100 or higher. Macro-ingredients may include sugar syrup, HFCS (High Fructose Corn Syrup), juice concentrates, and similar types of fluids. Similarly, a macro-ingredient base product may include sweetener, acid, and other common components. The syrups, sweeteners, and base products generally can be stored in a conventional bag-in-box container remote from the dispenser  100 . The macro-ingredients also may be positioned within the beverage dispenser  100  itself. Any type of container may be used herein. The macro-ingredients may or may not need to be refrigerated. 
     The micro-ingredients may have a reconstitution ratio ranging from about ten to one (10:1), twenty to one (20:1), thirty to one (30:1), or higher. Specifically, many micro-ingredients may be in the range of fifty to one (50:1) to three hundred to one (300:1). The viscosities of the micro-ingredients typically range from about 1 to about 100 centipoise or so. Examples of micro-ingredients include natural and artificial flavors; flavor additives; natural and artificial colors; artificial sweeteners (high potency or otherwise); additives for controlling tartness, e.g., citric acid, potassium citrate; functional additives such as vitamins, minerals, herbal extracts; nutraceuticals; and over-the-counter (or otherwise) medicines such as acetaminophen and similar types of materials. As described above, the acid and non-acid components of the non-sweetened concentrate also may be separated and stored individually. The micro-ingredients may be liquid, powder (solid), or gaseous form and/or combinations thereof. The micro-ingredients may or may not require refrigeration. Non-beverage substances such as paints, dyes, oils, cosmetics, etc., also may be used. Various types of alcohols may be used as micro or macro-ingredients. 
     Preferably, the micro-ingredients and the micro-ingredient sources  150  may be positioned within or about the beverage dispenser  100  itself as opposed to being remotely positioned in conventional bag in box containers or otherwise. By being positioned about the dispenser, we mean that the micro-ingredient sources  150  are positioned in close proximity to the dispenser  100  such as adjacent thereto, underneath, or in other near by positions. Any other type of storage arrangements may be used. Any type of container may be used herein. 
     The water source  130 , the macro-ingredient sources  140 , and the micro-ingredient sources  150  each may be in communication with a pump  160  or a metering device  170 . The control device  120  may control the pumps  160  and metering devices  170 . Generally described, the water source  130  and the macro-ingredient sources  140  each may be in communication with one of the pumps  160 . The pump  160  may be a conventional solenoid pump or a similar type of device. 
     The micro-ingredient sources  150  each may be in communication with one of the metering device  170 . The metering device  170  may be a positive displacement pump or a similar type of device. Such a positive displacement pump provides portion control for the more highly concentrated micro-ingredients. An example of the operation of a positive displacement pump is shown in commonly owned U.S. patent application Ser. No. 11/276,5486, entitled “Pump System with Calibration Curve” incorporated herein by reference. 
     For example, the positive displacement pump may be a solenoid pump, a gear pump, an annular pump, a peristaltic pump, a syringe pump, a piezo pump or any other type of positive displacement device that is designed to pump a fixed displacement for each pump cycle. 
     The pumps  160  and the metering devices  170  may be in communication with a dispensing nozzle  180 . The dispensing nozzle  180  preferably may be a multi-flavor dispensing valve capable of mixing a number of fluids at the same time. Examples of dispensing nozzles that may be used herein are shown in commonly owned U.S. patent application Ser. No. 10/233,867 (U.S. Patent Publication No. US 2004/0040983 Al), entitled “Dispensing Nozzle” and commonly-owned U.S. patent application Ser. No. 11/276,551 , entitled “Dispensing Nozzle Assembly”. U.S. patent application Ser. No. 10/233,867 and Ser. No. 11/276,551 are incorporated herein by reference. 
       FIG. 2  shows an example of such a dispensing nozzle  180 . Generally described, the dispensing nozzle includes a flow director  190  with a number of conduits extending therethrough. In this example, the flow director  190  may have a first conduit  200  and a second conduit  210  extending therethrough. The first conduit  200  may be used for water, other types of diluents, or other fluids. The second conduit  210  may be used for a macro-ingredient such as sweetened concentrate, sugar syrup, HFCS syrup, juice concentrate, or other type of fluids. Positioned beneath the flow director  190  may be a target  220 . The target  220  may include a number of vertically extending fins  230  that form a number of U- or V-shaped channels  240 . The water, the macro-ingredients, or other fluids may flow out of the flow director  190  and down along the channels  240  of the target  220  so as to begin mixing. 
     Positioned adjacent to the flow director  190  may be a tertiary flow assembly  250 . The tertiary flow assembly  250  may include a number of modules  260 . The modules  260  may have a number of conduits  270  extending therethrough. The conduits  270  may have differing sizes and configurations depending upon the nature of the intended flow therethrough. The modules  260  may be replaceable and interchangeable. Each of the modules  260  and the conduits  270  may be in communication with one of the micro-ingredient sources  150  or other types of fluids. The conduits  270  may be aimed towards the target  220  so as to mix the micro-ingredients or other fluid with the water, the macro-ingredients, or other fluid. Any number of micro-ingredients or other types of fluids may be used at the same time. 
       FIG. 3  shows an embodiment of the user interface  110 , an interface  300 . The interface  300  may include a set of predefined product buttons  310 . Each product button  310  may represent a different base product or product component. Each product button  310  may have a use indicator  320  that may signal to a consumer that a certain product or ingredient has been selected. A pour/cancel button  330  also may be used to activate the beverage dispenser  100  for the selected beverage. 
     The interface  300  further may include a number of additive buttons  340 . In addition to the predefined products defined by the product buttons  310 , the additive buttons  340  provide for the addition of additives such as flavorings, colorings, functional attitudes, and the like as described above. Typically, the additives will not be added until about eighty percent (80%) of the minimum drink size is poured so as to guarantee that there is no overdose effect if the drink is stopped prematurely. Additives generally would not be added for top-offs as the known drink size is not guaranteed. In the event that that the user presses the “cancel” button  330 , the additives will not be dispensed. The use indicator  320  may flash whenever an additive is being provided. The user interface  300  thus gives visible feedback to the consumer. 
     The interface  300  also may include portion buttons  350 . The portion buttons  350  may be conventional “small”, “medium”, “large”, “extra large”, and the like that correspond to the predetermined beverage sizes. 
     The interface  300  also may include intensity indicators  360 . The intensity indicators  360  may included LED&#39;s (Light Emitting Diodes) or a similar type of visual interface that shows the relative strength of the beverage. For example, different types of juices may be desired to be mixed together so as to provide a custom-blended beverage. The intensity indicator  360  also may be used to vary the amount of additives or even the nature and amount of the concentrate, sweetener, or other types of ingredients. 
     In addition to the interfaces described above, additional graphical interfaces may be provided. For example, nutritional information may be provided. Whenever a portion button  350  or an intensity button  360  is selected, the nutritional information that reflects the characteristics of the selected drink may be displayed. For example, the amount of calories in the beverage as mixed by the consumer may be displayed. The consumer may then have the option to change the nutritional value of the beverage as desired. The computer user interface  300  also may restrict and/or allow which and how much of various ingredients may be used. 
     The computer user interface  300  may provide an individual consumer with secure access by password, smart card, biometric identification, credit card, RFID, or otherwise. The user interface  300  may provide the consumer with formulations previously selected, promotions, and other types of information. The user interface  300  may restrict and/or allow which and how much of various ingredients may be used by a consumer. Consumer preferences also may be retained and used for new product development. 
     In addition to the graphical interface, the beverage dispenser  100  as a whole may supply dispenser statistics and troubleshooting information. For example, the delay time for the start of the pumps  160  or the metering devices  170 , the times for the vent and/or flush cycles, the portion cycles, etc. may be accessed through the user interface  110 ,  300 . This interface  110 ,  300  may be password or otherwise protected. The user interface  110 ,  300  may communicate and/or be accessed as needed with a network or other source for troubleshooting or repair and for notifications or alerts, for example, of a potential incorrect dose of ingredients. 
     In use, a consumer may select the desired beverage from the user interface  110 . The beverage dispenser  100  thus provides the consumer with the ability to create and blend numerous types of beverages as desired. The consumer can alter the ingredients as well as the intensity of the beverage to taste. As such, the consumer can submit an entire “recipe” for a custom beverage. Alternatively, the consumer can request a “branded” beverage. For example a “Cherry Coke®” beverage sold by The Coca-Cola Company of Atlanta, Ga. is more than just a “Coca-Cola®” beverage with the addition of a shot of cherry flavoring. Rather, it is a specific branded beverage with a consistent taste. The beverage dispenser  100  thus may provide as many “branded” beverages as may be available on the market in bottles, cans, or otherwise. 
     The interface  110 , with the control  120 , then instructs the individual pumps  160  and/or the metering devices  170  to dispense the appropriate ingredients in the appropriate proportions to the dispensing nozzle  180 . The mixed beverage then flows into the consumer&#39;s cup in the predetermined proportions for a given flow rate. The pumps  160  and the metering devices  170  may be pulsed on and off as desired to vary the flow rate. Such pulsing, for example, may ensure mixing of the micro-ingredients and may provide for a varied carbonation level. The beverage may be mixed at the dispensing nozzle  180  or anywhere downstream of one or more of the sources  130 ,  140 ,  150  (e.g., back room, in-line, etc.) Different flow rates and flow timing may be employed, e.g., certain fluid streams may be added early or late, certain fluid streams may be pulsed, etc. 
     The use of the individual pumps  160  and/or the metering devices  170  for the water source  130 , the macro-ingredient sources  140 , and the macro-ingredient sources  150  provides the ability to dispense the appropriate ingredients in the appropriate proportions for a given flow rate during a continuous pour. In other words, as opposed to a conventional batch operation where a predetermined amount of ingredients are combined, the beverage dispenser  100  provides for continuous mixing and flows in the correct ratios for a pour of any volume. The beverage dispenser  100  thus has applicability to conventional countertop devices, vending devices, and various types of bottling and filling devices. Although the invention is described in terms of the beverage dispenser  100 , the invention is applicable to the combination of any types of ingredients, wet or dry. Commonly owned U.S. patent application Ser. No. 11/276,549, entitled “Juice Dispensing System”, is specifically directed towards the use of the concepts described herein in the juice field. U.S. patent application Ser. No. 11/276,549 is incorporated herein by reference. 
     Referring again to  FIG. 1 , the beverage dispenser  100  also may include a consumer data system  400  in communication with the user interface  110  and the control device  120 . The consumer data system  400  may include a communication device  410 . The communication device  410  may include a video touch screen, a video screen and keyboard, or any other type of conventional input/output device. The communications device  410  may be part of the user interface  110  or a separate element. 
     The communications device  410  may prompt the consumer to input data on various type of biometric, health, lifestyle, and/or other types of information. Based upon the consumer&#39;s input, the control device  120  may analyze the data and may suggest a beverage or beverage ingredients that may be ameliorative, beneficial, or simply amusing the consumer in light of the data input. 
     Health parameters may include height, weight, blood pressure, blood glucose levels, insulin levels, cholesterol levels, bone density, heart rate, other types of metabolic information, body mass percentages, body temperatures, smoking history, pregnancy, overall medical history, etc. Lifestyle questions may include mood, intensity workouts, etc. Other types of categories may include the time of day, outside temperature, current events, team affiliations, etc. Any type of data may be requested. 
     Based upon the inputted data, the communications device  410  of the consumer data system  400  may suggest a beverage with various types of vitamins, minerals, herbal extracts, over-the-counter medicines, colorings, etc. A beverage with a specific amount of calories may be suggested. For example, a beverage with a “bones” package, i.e., Vitamin D and calcium; an “anti-oxidant package”, i.e., Vitamins C and E and zinc; a “heart package”, i.e., plant sterols and B vitamins; and many other additives or mixtures may be suggested. Once a beverage and/or the additives are selected, the appropriate micro-ingredients  150  or other elements may be dispensed via the pumps  160  and the metering devices  160  as is described above. The consumer data also may be stored and compared to the current data. 
     In addition to the communications device  410  as described above, the consumer data system  400  also may include one or more biometric sensors  420 . The biometric sensors may include automated devices to gather the desired health data or other information. The biometric sensors  420  may include a scale, a blood pressure cuff, a breathalyzer, a blood analyzer, a hair analyzer, an EKG, etc. Any type of monitoring device may be used herein. Any number of biometric sensors  420  may be used together. The biometric sensors  420  may be in communication with the control device  120  as described above. 
     It should be apparent that the foregoing relates only to the preferred embodiments of the present application and that numerous changes and modifications may be made herein by one of ordinary skill in the art without departing from the general spirit and scope of the invention as defined by the following claims and the equivalents thereof.
