BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to method and a device to make a single or a multiple serving of a select flavored, carbonated or noncarbonated beverage and, more particularly, to an apparatus and method for providing an individual serving ‘bottling plant’ for creating such beverages.
2. Description of the Related Art
While coffee makers and hot beverage makers have existed for quite some time, a relatively new market development has been created for single serve beverage appliances. Such machines are all designed to quickly brew a single cup of coffee or tea at a time. In the United States, the most commercially and widely available of these is made by Keurig Company, in which the grounds are pre-manufactured into prepared, single-serving pod called K-Cups®. Once the machine has heated the water, the user inserts a K-Cup® into the machine, places a mug under the spout, and presses an actuation button to allow hot water to be then dispensed through the K-Cup®. The K-Cup® forms an internal brewing volume, and allows for sufficient mixing and steeping time to form a brewed beverage before being filtered there through into the mug. In this manner, a cup of coffee, tea or hot chocolate is prepared. By omitting the K-Cup®, users can also merely prepare a mug of hot water, which can then be dispensed for use in making hot cocoa, tea, instant soup, or other hot drinks directly within the mug.
Devices of similar end use exist by FlaviaTM Beverage Systems (a division of Mars, Incorporate), NesspressoTM (of Nestlé Nespresso S.A., an operating unit of the Nestlé Group), Senseo® coffee brewing system from Dutch companies Philips and Douwe Egberts, a subsidiary of Sara Lee Corporation), and the TassimoTM Hot Beverage System (developed by Kraft Foods, Inc.), just to name a few.
To date, such single serve beverage appliances are targeted, and therefore limited, in their capabilities: hot beverages made by brewing, steeping or the like. Consequently, a need exists for an on-demand, in situ single dose cold beverage machine capable of creating sparkling or non-sparkling flavored waters, juices or sodas.
SUMMARY OF THE INVENTION
The problems associated with the making of on-demand, metered quantity of sparkling or non-sparkling flavored waters, juices or sodas are very much different than hose hurdles presented in the making of hot beverages made by brewing, steeping or the like. The teachings available from these commercially available hot beverage machines have been found to be very much non-analogous to the features and functions needed herein. Through significant trial and error, the present invention as disclosed herein teaches a single serving beverage maker that provides a means to select a flavor, to select an amount of flavor, to control a carbonation level, and to control the overall blend, ratio or type of beverage, such as, for example, a sparkling water, a sparkling soda, a sparkling juice, a non-sparkling energy drink, or the like.
While the prior art teaches that the use of a single serving ‘dose’ of coffee or tea provided in a fixed amount in a pod or small container can function as a mixing or steeping vessel, the present invention provides a means in which the beverage machine can control the blending and manufacturing process of the finished drink in a repeatable, consistent manner to achieve a designed end blend for a person; and to repeatedly and to consecutively make one of a number of such different single-serving beverages at home.
It is an object of the present invention to provide a means to make a single serving of a beverage within a user's home and on demand.
It is an further object of the present invention to be able to create beverages including flavored waters with vitamins/minerals, sport drinks, energy drinks, herbal teas or other carbonated or non-carbonated cold beverages in a manner that is individually customized.
It is another object of the present invention to provide a means to control the proportion of concentrate to diluent and total volume of the created beverage.
It is yet another object of the present invention to comprise a means to regulate and to control the pressure at which the beverage is carbonated.
It is still yet another object of the present invention to provide a means to regulate the level of carbonation.
It is a further object of the present invention to provide a means to regulate and the select the flavor of the sparkling beverage at the time the beverage is dispensed.
It is a final object of the present invention to provide all of the benefits the foregoing objects entail.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The best mode for carrying out the invention is presented in terms of its preferred embodiment as developed discoveries and improvements to those teachings described in the RELATED APPLICATIONS, incorporated by reference herein as if rewritten in their entirety, and herein depicted within the Figures.
1. General Description of the Device
Referring now to FIG. 1a and FIG. 1b, a preferred embodiment of an in-situ counter top beverage maker for carbonated and uncarbonated beverages, hereinafter referred to generally as a cold beverage maker or beverage maker 10, is shown. An outer housing 12 covers and contains the modular internal systems, while providing an aesthetically pleasing industrial design. While many of the teachings and improvements of the present invention can be achieved without limitation to size or form factor, one additional key improvement taught by the present disclosure is to be able to provide a beverage maker 10 that can fit conveniently onto a standard kitchen counter top. As such, it is anticipated that the outer housing 12 would be capable of having an overall height of less than 15.5 inches, with a preferred outer dimension being within an overall cube of 15.5 inches high by 14 inches wide by 12.75 inches deep.
The housing 12 further supports a control area 22 forming an operational interface or user control interface, as described in greater detail below. A filling area, generally shown as 209 includes a piercing mechanism 210 (as described in greater detail below) which allows for mixing of chilled carbonated or noncarbonated water with a single portion flavor concentrate container above the base splash plate 16.
As shown, the housing 12 is affixed to a base 14, and provided with additional structural integrity and which further functions as an attachment member for connection of the various system components as will be described in greater detail below. A base splash plate 16 or overflow tray is further supported by the base 14 and is of a size, shape and location as to provide for collection of spilled or otherwise mis-dispensed fluids. According to the preferred embodiment presented herein, the overflow tray is adapted to collect up to 16 fluid ounces of liquid in that the present design has been selected for dispensing of either eight or sixteen ounce beverages, as will be described in greater detail below.
Beverage making fluid is anticipated as being substantially water. However, it would be obvious to a person having ordinary skill in the relevant art than any potable fluid capable of being used as a beverage could be utilized as an obvious equivalent (such as, for example, fruit or vegetable juices). Fluid is introduced to the beverage maker 10 through a pitcher assembly 18. The pitcher assembly 18 is best shown in conjunction with FIG. 3a through FIG. 4b, the pitcher assembly 18 comprise a pitcher body 20 forming a fluid reservoir 24 contained by a removable pitcher lid 22 capable of sealingly closing the mouth of the pitcher body 20. It is anticipated that the pitcher assembly 18 will be nestable within the base 14 but removable from the machine housing 12 such as to allow the assembly 18 to function as a beverage pitcher capable of being placed in a refrigerator (not shown) such as to chill any fluid contents. The pitcher body 20 forms a discharge orifice 25 formed in the bottom of the pitcher body 60 (best shown in FIG. 3d) which allows for fluid communication between the fluid reservoir 24 and a water pump 106 that further communicates with a carbonation chamber 80 as described in greater detail below. As shown in conjunction with FIGS. 4a and 4b, a spring urged pitcher valve assembly 26, provides a mechanism for opening the discharge orifice 25 upon nesting of the pitcher body 20 within the base 14, while allowing for automatic closure upon removal. In such a manner the user can remove the assembly 18, fill the body 20, and return the base 14 to provide delivery of the liquid contents to pre-prime the machine.
While the selection of any particular volume of water reservoir 20 would be a design choice to accommodate an individual performance requirement, shown in the present invention is a 64 fluid ounce water reservoir 20 formed as a blow molded volume. It is anticipated that a person having ordinary skill in the relevant art, in light of the teachings and goals of the present invention, would envision as an alternate design choice to incorporate a rigidly attached (i.e. non-removable) fluid reservoir mounted within or on the housing 12 and having access through a fluid fill door. It is anticipated that such a functionally equivalent design alternative would require a means of chilling the contents of such a reservoir, a means for insulating such a reservoir, or both.
The fluid provided from the pitcher assembly 18 is thereafter directed to be carbonated (optional), blended, and discharged to a drinking vessel as flavored water with vitamins/minerals, sport drink, energy drink, herbal tea or other carbonated or non-carbonated cold beverages in a manner that is individually customized. The present application incorporates the teachings and improvements developed from those inventions disclosed in the RELATED ART listed above, while disclosing additional improvements which shall be identified and described alone in specific detail. It will become obvious to a person having ordinary skill in the relevant art, in hindsight light of the teachings of the RELATED ART, that the specific details of these inventions described alone, can and ought to be understood in conjunction with the operation of the overall invention. With this in mind, the current invention can be broadly construed in terms of the following additional improvements: carbonation devices; carbonation methods; syrup (i.e. flavor or non-water liquid component) interaction or control; and, piercing mechanism.
2. Detailed Description of the Carbonation Devices
It has been taught as a key element of the present inventions that a pressure vessel assembly of a fixed volume be utilized for the absorption of carbon dioxide into the liquid for use in the manufacture of a sparkling type beverage. In the preferred embodiment, as shown in generally in FIG. 2 and in greater detail in conjunction with FIGS. 5a and 5b, the carbonation assembly 50 is shown having a carbonation chamber 80 shown in its preferred embodiment comprising a 16 oz. canister manufactured sufficiently to retain pressurized fluid in a safe manner. One particular feature and improvement of the present teachings include the function of the carbonation chamber 80 as a ‘dose carbonator’. For purposes of the present invention a ‘dose carbonator’ refers to a controlled volume in which temperature, pressure, water volume, and, ultimately, CO2 absorption can be performed and controlled. As such, the internal volume is designed to hold a dosed liquid volume, plus an additional head space to allow for addition of pressurized carbon dioxide, as described generally herein and in greater detail below. It is anticipated that the total internal volume less the volume of the head space is equal to 14 fluid ounces for dispensing a 16 ounce beverage. In this manner, flavorings, essences and syrups are blended in a fixed proportion of 2 ounces flavoring to 14 ounces of chilled (or carbonated) water. Further, it is anticipated that within the teachings of the present invention alternate internal volumes can be provided such as to provide for different size beverages, or alternation between different sized beverages. In the present embodiment, the use of a capacitance sensors 82, 84 located along the vertical sidewall of the carbonation chamber 80 can be used to identify and control filling to a desired level, with the upper capacitance sensor 82 located at a level corresponding to the volume associated with the proportions identified above for a larger mixed beverage (i.e., 16 total ounces of consumable beverage), while the lower capacitance sensor 84 is located at a level corresponding to a different size, anticipated herein as being at a level indicating the introduction of 7 fluid ounces of liquid for allowing for the dispensing a finished beverage of 8 ounces. It is anticipated that a person having ordinary skill in the relevant art, in light of the teachings and goals of the present invention, would envision as an alternate design choice variations in the number of level sensors or corresponding volumes of finished beverages as functionally equivalent design alternatives or obvious extensions of the teachings herein, or both.
The use of the type and style of chamber 80 as shown has been found to have benefits in use. The continuous vessel volume with minimal penetrations minimizes unwanted leaks of liquids or gases. The single entry orifice can be sealed with O-ring seals, and may allow the CO2 injection into the chamber 80 to be done through an entry tube 86 that terminates below the anticipated liquid level, thereby allowing for the CO2 to be bubbled through the liquid on its way into the chamber. However, the CO2 will eventually collect at the apex of the chamber, and as such a continuous vessel volume therefore results in the minimizing of the surface area of the liquid-gas interface, thereby decreasing the effective and rapid mixing and absorption of carbon dioxide. Improved carbonation methods, as described herein below, have been therefore developed in order to minimize the mixing or dwell time required to get desired or complete carbonation.
Other challenges of such a chamber 80 design is the use of metal forming results in limited options for level detection. While contact sensor can, of course, be implemented by incorporating additional orifices into the chamber sidewall, non-contact sensors and capacitive type sensors are of limited use with such a design. Further still, the thermal conductivity of a metal sidewall increases the heat flux into the liquid contents, thereby warming the resulting cold beverage. As such, as an alternate embodiment for a carbonation chamber 80 the use of a blow molded plastic materials having lower thermal capacities may be used to minimize the absorption of heat into the liquid contents during the carbonation cycle.
In either embodiment it is anticipated that the temperature of the internal fluid contents of the carbonation chamber 80 can be obtained to or maintained at 37° F. with the introduction into the pitcher assembly 18 of chilled water at or below this temperature; it is further anticipated that the pressure of the internal volume can, and should, be maintained at between 125 to 150 psi. This provides an optimum condition for absorption of CO2 into the water.
3. Detailed Description of the Carbonation Methods
In order to obtain a pressure of between 125 to 150 psi, a cylinder 60 of high pressure CO2 is in fluid communication with the internal volume of the carbonation chamber 80 through the CO2 inlet of the junction block 100. The junction block 100 functions as the manifold for fluid flow of liquid and pressurized gas as directed by the CO2 solenoid 102, the vent solenoid 104, or liquid supply pump 106 that are each in fluid communication with their respective systems. A pressure transducer 110 controls the introduction of the 1800 psi working pressure of CO2 from the cylinder 60 to the CO2 inlet. As identified previously in the RELATED APPLICATIONS, in order to provide consistent, available, and economical source of CO2, it is anticipated that the beverage machine 10 of the present invention would take advantages of an existing source of such compressed carbonating gas such as a common CO2 gas propellant as are found for use in powering paintball guns, which typically comes in the three sizes of 9 oz, 12 oz and the 20 oz. It is anticipated that a person having ordinary skill in the relevant art, in light of the teachings and goals of the present invention, would envision any of these sizes as functionally equivalent design alternatives or obvious extensions of the teachings herein, or both.
In order to optimize the absorption of the fixed dose of carbonated water, it is anticipated that the head space should be vented of any residual air and filled with CO2. This can be done by driving CO2 through a discharge straw 120 and out through the vent valve 106. It is further anticipated that a pulsed introduction of CO2 into the CO2 inlet would allow for improved incremental carbonation of the water until an optimum pressure of between 125 to 150 psi is obtained within the volume and maintained by the vent valve 106.
Referring in conjunction to FIG. 6, the operation of the control solenoid for controlling the flow of CO2 to the chamber 80 is described and shown with the resulting pressure profile. It has been found through significant testing that the introductions of pressurized CO2 in a batched, ramped fashion would require a significant dwell time to allow for adequate carbonation of the contents. Alternately, the use of pulsed charges of CO2 has been found to be more effective at urging absorption into the liquid, but only at higher pressures. In addition, the use of a continuous pulsed introduction of CO2 would result in a long cycle time, to be found unacceptably long to the consumer in addition to allowing additional time for warming of the beverage through heat soaking. It has been found to be an optimum cycle to provide an initial pressurization of the carbonation chamber (as shown by slope A), followed by pulsing the CO2 into the vessel pressure until it maintains a constant maximum pressure (As shown by slope B), allows for greater absorption into the liquid at an acceptable overall cycle time. Once fully charged, an optimal dwell time of about approximately 8 seconds (as shown by slope C) has been shown to provide an optimal overall cycle and dwell time to attain adequate carbonation at a reasonable overall cycle type. This pressure is then vented (as shown in slope D) prior to dispensing of the liquid (as shown in slope E). Additionally, the venting of the carbonation chamber 80 during liquid discharge has also been found useful in releasing any vacuum created by dispensing of the mixed beverage, as will be described in greater detail below.
4. Detailed Description of Syrup Interaction or Control
Operation of the present invention is best described in conjunction with FIG. 7 in which an in-situ counter top beverage maker for carbonated and uncarbonated beverages according to the preferred embodiment of the present invention. The level sensor within the fluid reservoir identifies the presence of a sufficient amount of liquid from which to form a mixed beverage. If present, upon initiation the pump will operate for a predetermined cycle period for providing the carbonation chamber with sufficient liquid (either 7 ounces or 14 ounces) depending upon the size beverage selected. A thermistor measures temperature of the fluid portion and may be used to control the amount of CO2 pressure needed for saturation. If sufficient CO2 pressure exists in the canister 60 then the pump is powered and the vent valve opened to allow for filling of the canister with fluid. Once full, the carbonation chamber is pressurized in the manner described above to allow the pressurized canister to pressurize the carbonation chamber up to the appropriate saturation pressure (approximately 125 to 150 psi). A pressure transducer may be used in fluid communication with the carbonation chamber through the junction block 100. If the carbonation chamber experiences a pressure above the desired target pressure, a high pressure relieve valve may then release gas until the excess pressure is relieved.
In conjunction with the preferred embodiment of the present invention, the beverage maker 10 incorporates the Central Processing Unit for operationally controlling all of the internal controls. When the beverage maker 10 is activated, a user interface displaced on the operational control unit 24 will indicate status, cycle step and operation by use of illuminated LED driven directly from the internal power supply.
However, unlike brewed beverages such as coffee or tea where users are accustomed to variation in output and routinely control concentration through steeping time, level of grind of the beans, or sheer quantity of ground beans, in carbonated or non-carbonated beverages the consumer expectation is one of greater consistency. Further, with the use of a fixed volume ‘dose carbonator’ a greater need exists for verification and authentication of the type, quality, quantity, concentration, etc. of the flavor concentrate or non-diluent component. In the present invention, the use of individually packed, single use disposable flavor cups 200 is anticipated which include a mixing area 200a of a volume greater than the volume that will be filled with the flavors of choice to make sparkling flavored water and a syrup to make vitamin fortified and mineral added, low sugar soda pop. Additionally, a coded authentication mechanism is anticipated as being carried by the cup 200, and identified by the beverage maker 10, would allow the settings of the beverage maker 10 to be pre-set to accommodate normal condition anticipated for use with a particular beverage. By way of examples, the beverage size could be selected from an 8 oz beverage or a 16 oz beverage; the beverage could be a sparkling orange drink, or a non-sparkling herbal water. Since such a great number of permutations exist, the use of coding the system defaults within the flavor cup 200, and then identified by and used to adjust the settings of the beverage maker can eliminate many errant selections. Additionally, by merely identifying and selecting default settings, the machine 10 will still allow for the user to confirm or modify them prior to operation. In this manner, the user can still create a carbonated herbal beverage, or a non carbonate cola, for example, as well as increasing or decreasing the amount of carbonation desired.
In order to accomplish the validation and verification of a properly provided flavor cup 200, the coded authentication mechanism formed of an RFID tag (or transponder device) of a commonly available type utilized to store and remotely retrieving data. An RFID tag is applied to or incorporated into flavor cup 200, preferably within the cup's closure lid, and carries with in a variety of validating or authenticating information, including, but no limited to: authorization code or codes; flavor cup content information such as, for example, source, date expiration, flavor, and the like; and, default beverage selection data for purposes of presenting the beverage maker's default settings. Most RFID systems contain at least two parts: an integrated circuit to store and process information, to modulate and demodulate a (RF) signal, and to perform other specialized functions; and, an antenna to receive and transmit the signal. Chipless RFID technology allows for discrete identification of tags without integrated circuit, and these tags can be printed directly onto the flavor cup 200 or its foil cover at a lower cost than traditional ones. Such passive tags require no internal power source and are only active when a nearby-reader powers them. It is anticipated that the RFID reader with antenna is incorporated with the beverage maker 10 and in electronic communication with the Central Processing Unit in order to allow for retrieval of information from the RFID tag and implementation of system default settings in response to the retrieved information. These default settings are anticipated as including: authentication or verification of operation such as, for example, a “go”/“no-go” setting; beverage volume; carbonation or non-carbonation; level of carbonation; and the like. This ability to interact the flavor cup 200 directly with the control and operation of the beverage maker 10 allows the settings of the beverage maker 10 to be pre-set to accommodate normal condition anticipated for use with a particular beverage. This ability to pre-set defaults is just one additional feature that allows the beverage maker 10 to provide a quality, consistent and repeatable beverage, even when used with the wide range of varieties of cold sparkling or non-sparkling beverages that are anticipated as being prepared, as well as to accommodate the development of ever changing new beverage selections.
5. Detailed Description of the Piercing Mechanism
Referring now to FIGS. 8a and 8b, the flavor cup is shown in two embodiments, one having a capacity of slightly more than 1 oz., but will be filled with 1 oz. syrup flavor concentrate, as noted as 200 and the second one having a capacity of slightly more than 2 oz., but will be filled with 2 oz. syrup flavor concentrate and noted as 201. Each cup 200 functions similarly in conjunction with the piercing mechanism 210 shown best in conjunction with FIG. 9. A custom vacuum formed design incorporates a indexing ridge 202, and a sealed foil cover 203 covers and seals the flavor cup 200. When placed in the mixing chamber 125, the foil 203 is pierced on the top and, in doing so, will allow the cup to move downward and be pierced a second time from the bottom. An upper peripheral flange 205 therein support the cup. When the piercing needle approaches from the top of the cup, it will be engaged and sealed about its perimeter by the foil and around the piercing cite.
As shown in greater detail in FIG. 10a-10c, the piercing needle 300 is shown with the features and functions that allow the flavor cup 200 to adequately function as a mixing chamber for carbonated or noncarbonated chilled water and flavor syrup. The needle 300 forms an upper shank 302 separated by a lower blade 304 by a narrowed constrictive section 302. An upper vent hole 310 is formed in the upper shank 302. A lower vent hole 312 is formed in the lower blade section and in connected by a slot 314 to a discharge orifice 320 terminating at the lower blade 304. The unique design for the piercing needle 300 provides the optimum mixing of carbonated or not carbonated water with the flavor syrup contained with the individually packed, single use disposable flavor cups 200.
The cups 200 are anticipated as including a mixing area 200a of a volume greater than the volume that will be filled with the flavors of choice to make sparkling flavored water and a syrup to make vitamin fortified and mineral added, low sugar soda pop. The foil cover 203 is pierced on the top by the needle 300; the needle 300 is subsequently urged downward to further pierce the bottom of the cup 200. When the piercing needle is driven down through the top of the cup, it will be engaged and sealed about its perimeter by the foil and around the piercing site, with the upper hole 310 forming an exit orifice from the shaft of the needle 300 into the cup. The constriction 304 formed below the upper hole 310 provides hydraulic resistance to fluid being discharged through the needle 310 and therein causes the discharged fluid to want to flow though the upper hole 310 and not down past through the constriction 304. This will cause the discharged liquid, carbonated or uncarbonated, to discharge into the volume of the flavor cup 200 in a swirling fashion, thereafter allowing the cup 200 to function as a mixing chamber between carbonated or noncarbonated chilled water and the flavor syrup contents. This blended fluid is then allowed to drain down the lower orifice 312 and discharged into a waiting receiving vessels such as a cup or mug.
As described above, a preferred embodiment, as anticipated at the time of filing, is identified and described as exemplary of the teachings of the present invention. However, the disclosure is not intended to be narrowly construed by this exemplary embodiment, as one skilled in the art would know that the operational and functional equivalent of many of the components, systems, steps and processes taught herein could be modified or replaced by equivalent components, systems, steps and processes and still remain within the spirit and teachings of the present invention.
The present invention provides improvements to a novel means to make a customized single-serving of chilled, sparkling beverage at home. A complete line of home, office and commercial appliances will have the basic attributes of a Sparkling Beverage Maker that will:

    
    
        Give the consumer the ability to make on demand his/her choice of beverage in a single-service glass either a sparkling water with or without flavor, a sparkling fruit juice or an enhance soft drink, low in sugar with vitamins and minerals.
        Give the consumer to ability to regulate and control the beverage temperature.
        Give the consumer the ability to regulate the level of carbonation from low, medium and high.
        Give the consumer the ability to choose and regulate the flavor of sparkling water as the dispensing takes place for a continual and immediate freshness.
        Gives the consumer the ability to switch over to making a sparkling fruit juice.
