COCA-COLA® is a registered trademark of The Coca-Cola Company, Atlanta, Ga., U.S.A. Other names, symbols, designs, or logos used herein may be registered trademarks, trademarks or product names of The Coca-Cola Company or other companies.
This invention relates to product dispensers, and in particular, relates to systems and methods of dispensing control for a product dispenser.
Conventional product dispensers can pour a beverage by combining a syrup, sweetener, and/or water. To create a finite variety of beverage selections different kinds of syrup can be offered. This typically results in being able to offer a finite number of branded and non-branded beverage selections. As an example, a single prior art dispenser using several different kinds of syrup might be able to offer limited choices of COCA-COLA™, DIET COCA-COLA™, SPRITE™, and a few other branded or non-branded beverage selections.
One problem with these types of conventional product dispensers is that only a limited number of drinks can be offered. As such, conventional product dispensers may be limited in being able to offer the consumer what they want. In this regard, consumers want a wider menu of beverage selections and the ability to customize their beverage. Research suggests that they want more beverage variations even for a traditional branded beverage. For example, offering COCA-COLA™, COCA-COLA™ with lime, CHERRY COCA-COLA™, VANILLA COCA-COLA™ and numerous other types of COCA-COLA™ beverage variations. Offering all the variations possible for a single drink brand such as COCA-COLA™ are impractical in conventional product dispensers in part because conventional product dispensers have limited capacity and selection capability. They may not offer the consumer what the consumer wants, that is, a complete variety of choices for all types of branded and non-branded beverages.
Product 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. These 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 product 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 product dispenser itself. The product dispenser preferably can give the consumer multiple beverage options such that the consumer has the ability to customize his or her beverage as desired.
In certain instances, some beverages may have different carbonation or foaming characteristics when poured or otherwise dispensed. This occurrence may be due to the differences in the ingredients used to formulate each beverage. In any instance, non-carbonated beverages will “top off” consistently when poured or otherwise dispensed in a container, such as a cup. When certain carbonated beverages are poured or dispensed, depending on the amount of carbonation, each beverage may have one or more additional amounts added during subsequent pours or dispenses to “top off” the beverage in a container or cup. In conventional product dispensers, the operation to “top off” different beverages can be a time consuming, manually initiated operation that requires the operator to individually “top off” each poured or dispensed beverage. When an inexperienced user or operator frequently pours or dispenses different beverages, various amounts of the beverage may be wasted in learning how to “top off” each different beverage. Even experienced users or operators may waste beverages when changing between different poured or dispensed beverages.
Some or all of the above needs and/or problems may be addressed by embodiments of the invention. Embodiments of the invention can include systems and methods of dispensing control for a product dispenser. In one embodiment, a system or product dispenser can be provided. The system or product dispenser can include a plurality of beverage ingredient sources comprising a respective beverage ingredient, a plurality of beverage supply lines in respective communication with the plurality of ingredient sources, at least one pump in communication with the plurality of beverage supply lines, and a controller in communication with the at least one pump and operable to execute a set of instructions. The set of instructions can be operable to store data associated with a prior poured beverage, provide a command for a user to dispense the prior poured beverage in a subsequent pour, and after selection of the command, based at least in part on the data associated with a prior poured beverage, dispense a subsequent beverage similar to the prior poured beverage.
Another embodiment can provide a computer program product. The computer program product can include a computer readable medium having computer readable program code, the computer readable program code operable to be executed to implement a method for operating a product dispenser. The method can include storing data associated with a prior poured beverage, providing a command for a user to dispense the prior poured beverage in a subsequent pour, and after selection of the command, based at least in part on the data associated with a prior poured beverage, dispensing a subsequent beverage similar to the prior poured beverage.
Another embodiment can provide a method of operating a product dispenser. The method can include storing data associated with a prior poured beverage, providing a command for a user to dispense the prior poured beverage in a subsequent pour, and after selection of the command, based at least in part on the data associated with a prior poured beverage, dispensing a subsequent beverage similar to the prior poured beverage.
In yet another embodiment, a method for operating a product dispenser can be provided. The method can include dispensing a first product, storing information associated with dispensing the first product, and initiating a command to dispense a second product, wherein the second product is similar to the first product.
Additional systems, methods, product dispensers, apparatus, aspects, and features are realized through the techniques of various embodiments of the invention. Other embodiments, aspects, and features of the invention are described in detail herein and are considered a part of the claimed invention. Other embodiments, aspects, and features can be understood with reference to the description and to the drawings.
The detailed description explains various embodiments of the invention, together with aspects and features, by way of example with reference to the drawings.
As used herein, the terms “beverage forming dispenser,” “product dispenser,” “beverage dispenser,” “dispenser apparatus,” and “dispenser” refer to a device which dispenses a product such as a beverage, a fluid, or a consumable product.
As used herein, the terms “product” and “beverage,” and their pluralized forms, are used synonymously, and embodiments of the invention should not be limited in scope by the use of either term.
As used herein, the terms “top off” and “topping off” refer to an operation used to add more product, beverage, fluid, other substances or materials, or any combination thereof into a container to fill the container to a desired level or volume.
Embodiments of the invention can include systems and methods of dispensing control for a product dispenser. Other embodiments of the invention can include systems and methods for operating a product dispenser. Certain embodiments of the invention can be particularly useful when operating a product dispenser, such as a beverage dispenser. In one instance, when a user or operator is using a product or beverage dispenser to fill a container, such as a cup, the product or beverage dispenser can automatically pour or dispense a prior or last poured product or beverage. In this manner, a user or operator can minimize the time spent in topping off a subsequent product or beverage being poured or dispensed with a product or beverage dispenser. Thus, certain embodiments of the invention can provide a technical solution to the time consuming problem of topping off a product or beverage using a product dispenser, such as a beverage dispenser.
The circumstances provided above are for illustration only, and are not intended to be limiting. One will recognize other circumstances for applying embodiments of the invention, and the applicability of those embodiments to other product and/or beverage dispenser technologies.
Turning now to the drawings in greater detail, in which like numerals indicate like elements throughout the several views,
The product 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 (High Fructose Corn Syrup), 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. In another example, 106 unique ingredient sources 140, 150 may be present in a product dispenser, such as 100, in accordance with an embodiment of the invention. One will recognize that other embodiments of the invention can include fewer or greater numbers of ingredient sources 140, 150.
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 centipoise or higher. Macro-ingredients may include sugar syrup, HFCS, 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 product dispenser 100 itself. Any type of container may be used herein in accordance with embodiments of the invention. 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.
In certain instances, the micro-ingredients and the micro-ingredient sources 150 may be positioned within or about the product dispenser 100 itself as opposed to being remotely positioned in conventional bag in box containers or otherwise. By being positioned about the dispenser, the micro-ingredient sources 150 can, for example, be 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 in accordance with embodiments of the invention. The macro and/or micro-ingredient sources may optionally be located remotely from the dispenser 100, such as in a back room, connected to the dispenser 100 with conventional tubing. Furthermore, any type of container may be used herein in accordance with embodiments of the invention.
The water source 130, the macro-ingredient sources 140, and the micro-ingredient sources 150 each may be in communication with a respective pump 160, sensor 165, and/or a metering device 170 via a respective supply line 175. The control device 120 may control the pumps 160, sensors 165, 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 a respective metering device 170 via a respective supply line 175. 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.

In the embodiment shown, the last poured button 306 can be used to initiate a subsequent pour or dispense operation of the last poured or dispensed product or beverage. For example, the last poured button 306 can initiate a command which pours or dispenses the last poured or dispensed product or beverage. In certain instances, the last poured button 306 can indicate other information associated with the last poured or dispensed product or beverage, such as the product or beverage brand name. In other instances, combinations of products or beverages may have been the last poured or dispensed product or beverage, in which case, information indicating the combination can be displayed or otherwise output. In another embodiment, the last poured button 306 or another button, can initiate a command which pours or dispenses the last poured or dispensed product or beverage multiple times.
In the embodiment shown, the series of previously poured buttons 308A-308N can be used to initiate a pour or dispense operation of more of the previously poured or dispensed products or beverages. For example, the series of previously poured buttons 308A-308N may display in a sequential order the previous 10 poured or dispensed products or beverages. Generally, when the interface 300 is used, a user or product dispenser operator can select from one or more of the series of previously poured or dispensed products or beverages, which can initiate pouring or dispensing subsequent products or beverages similar to the selected previously poured or dispensed products or beverages. In certain instances, one or more of the series of previously poured buttons 308A-308N can indicate other information associated with the previously poured or dispensed product or beverage, such as the product or beverage brand name and/or the amount or volume poured or dispensed. In other instances, combinations of products or beverages may have been the previously poured or dispensed product or beverage, in which case, information indicating the combination can be displayed or otherwise output. In other embodiments, buttons or commands for any number of previously poured or dispensed products or beverages can be displayed. In another embodiment, each of the series of previously poured buttons 308A-308N or another button, can initiate a command which pours or dispenses a selected previously poured or dispensed product or beverage multiple times.
In one embodiment, a user can select from any number of particular “branded” beverages. For example, icons associated with the “Cherry Coke®” beverage and the “Coca-Cola®” beverage sold by The Coca-Cola Company of Atlanta, Ga. can be displayed on a user interface, such as 300 in
In certain embodiments, the interface 300 operating alone or in conjunction with a communications device, such as 127, and/or a biometrics sensor, such as 128, may provide a user, such as an individual product dispenser operator, with secure access by password, smart card, biometric identification, credit card, RFID, or otherwise. In other embodiments, user or operator preferences also may be retained and used for future product dispenser maintenance.
In addition to the graphical interface, a product dispenser 100 as a whole may provide other product 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 user such as a product dispenser operator, for example a food service employee and/or dispenser technician, may select a last poured or previously poured beverage from the user interface 110 to dispense as the desired next poured beverage. After user selection of an initial desired beverage via the user interface 110, the control device 120 can initiate pouring of the desired beverage. The control device 120 can store information associated with the last poured beverage in memory 124 or other data source. Based at least in part on the stored information, the control device 120 can provide a user selectable button or command on the user interface 110 to select the last poured or previously poured beverage. When the user selectable button or command is implemented by a user, the control device 120 can receive the command or corresponding signal from the user interface 110 and communicate with or control one or more of the sources 130, macro-ingredient sources 140, 150, supply lines 175, 185, and pumps 160 to facilitate pouring a subsequent beverage similar to the last poured or previously poured beverage.
For example, a user may select a desired beverage Product A via the user interface 110, wherein the control device 120 can initiate pouring of the desired beverage in a container, such as a cup. The control device 120 can store information associated with the last poured beverage in memory 124 or other data storage device. The stored information may include a predefined volume and recipe of the last poured beverage including any recipe adjustments and user-entered data associated with adjusting the recipe. Based at least in part on the stored information, the control device 120 can provide a user selectable button or command, such as a last pour button 306, on the user interface 110 for the user to select the last poured beverage. When the last pour button 306 is selected by a user, the control device 120 can receive the command or corresponding signal from the user interface 110 and communicate with or control one or more of the sources 130, macro-ingredient sources 140, 150, supply lines 175, 185, and pumps 160 to facilitate pouring a subsequent beverage similar to the last poured beverage. Typically, the control device 120 obtains or receives the stored information from memory 124 or other data storage device, and based at least in part on the stored information, can communicate with or control one or more of the sources 130, macro-ingredient sources 140, 150, supply lines 175, 185, and pumps 160 to facilitate pouring a subsequent beverage, similar to the last poured beverage, in a container, such as a cup.
In another example, a user may select a desired beverage Product C via the user interface 110, wherein the control device 120 can initiate pouring of the desired beverage in a container, such as a cup. The control device 120 can store information associated with a previously poured beverage in memory 124 or other data storage device. The stored information may include a predefined volume and recipe of one or more previously poured beverage including any recipe adjustments and user-entered data associated with adjusting the recipe. Based at least in part on the stored information, the control device 120 can provide a user selectable button or command, such as a previous pour button 308A, on the user interface 110 for the user to select the previously poured beverage. When the previous pour button 308A is selected by a user, the control device 120 can receive the command or corresponding signal from the user interface 110 and communicate with or control one or more of the sources 130, macro-ingredient sources 140, 150, supply lines 175, 185, and pumps 160 to facilitate pouring a subsequent beverage similar to the previously poured beverage. Typically, the control device 120 obtains or receives the stored information from memory 124 or other data storage device, and based at least in part on the stored information, can communicate with or control one or more of the sources 130, macro-ingredient sources 140, 150, supply lines 175, 185, and pumps 160 to facilitate pouring a subsequent beverage, similar to the previously poured beverage, in a container, such as a cup.
In any instance, the product dispenser 100 thus provides a user with the ability to pour or dispense a last poured or previously poured beverage for any number of or all of the beverages offered by the product dispenser 100 as desired. The user can select a last poured or previously poured button or command, which can obtain or otherwise retrieve stored information associated with a last poured or previously poured beverage. As such, the user can subsequently pour a beverage similar to the last poured or previously poured beverage with a single operation using the product dispenser 100.
Embodiments of the invention thus have applicability to conventional countertop devices, vending devices, and various types of bottling and filling devices. Although embodiments of the invention are described in terms of the product dispenser 100, embodiments of the invention are applicable to the combination of any types of ingredients, wet or dry. For example, commonly owned U.S. patent application Ser. No. 11/276,549, entitled “Juice Dispensing System,” is specifically directed towards certain concepts related to the juice field.
