     BACKGROUND 
       [0003]    Numerous types of water dispensers are available, including dispensers for chilled, unchilled (e.g., room temperature), and heated water. Some water dispensers dispense carbonated water. Water dispensers can include a reservoir or a pressurized source. Water dispensers may be stand alone devices, or incorporated into an appliance such as a refrigerator. 
         [0004]    Most commercialized devices for carbonating water use carbon dioxide sprayed into a water container: the result obtained with this process is very poor and the carbonation of water is weak and does not last too long. Devices for producing and dispensing carbonated beverages in water dispensing units, instead, typically employ a carbonating tank, called a saturator, and a high-pressure water pump. Carbonated water is produced by pressurizing the saturator tank with carbon dioxide and filling the tank with chilled water. Due to the high pressures resident in the saturator tank, typically around 70 psi, a relatively expensive high pressure water pump is required to inject water into the tank. Furthermore, under the conditions in the saturator tank, the carbon dioxide takes time to dissolve into to the water and achieve a palatable level of carbonization. Accordingly, the saturator is typically large enough to hold a ready supply of carbonated water for dispensing and does not create new carbonated water instantaneously on demand. To maintain this supply, two or more sensors-and associated electronic controls—are used to start the high pressure pump and inject water into saturator when the level of carbonated water in the saturator falls below a set threshold and then stop the water injection when the tank fills to an appropriate level. 
         [0005]    These typical carbonization devices take up a relatively large amount of space and require expensive and complicated electronic and hydraulic control systems. Due to this complex structure, these devices are noisy, use significant amounts of energy, and require frequent maintenance. 
         [0006]    Flavored beverages may be made by mixing water with a flavoring material (referred to herein as generally as “flavor” or “flavor content”). Flavor content may take a number of forms including liquid (e.g., a syrup), soluble or insoluble solids (e.g., powders, tea leaves, coffee grounds, etc.). Flavored beverages include cold beverages (e.g., flavored soda, fruit flavored drinks, etc.) or hot beverages (e.g., coffee, tea, hot cocoa). 
         [0007]    Today&#39;s on-the-go consumers increasingly expect to have access to flavored beverages with a large number of flavor options provided in a convenient, clean, easy to use form. For example, convenience stores typically stock dozens of types beverages, including flavored waters, carbonated sodas, coffee, tea, etc. These beverage are available in a variety of sizes and containers.

     DETAILED DESCRIPTION 
       [0044]      FIG. 1  shows a functional block diagram of a system  100  for dispensing water. The system  100  includes three water sources  101 ,  102 , and  103  (although any other number may be used) that deliver water to a single flow dispenser  200  for dispensing. For example, in some embodiments, the system  100  is of the type described in Application No. 61/600,451 incorporated by reference above. 
         [0045]    As shown, the sources include a chilled carbonated water source  101 . Carbonated water source  101  may include an in-line carbonator, e.g., of the type described in U.S. patent application Ser. No. 12/772,641 filed May 3, 2010 entitled “APPARATUSES, SYSTEMS AND METHODS FOR EFFICIENT SOLUBILIZATION OF CARBON DIOXIDE IN WATER USING HIGH ENERGY IMPACT,” the entire contents of which are incorporated herein by reference. This reference describes an apparatus that can be placed in a water line path to create carbonated water for dispensing. The apparatus accepts carbon dioxide and water through an inlet path. From there the flow of carbon dioxide and water are passed through one or more dispersion elements arranged within the conduit to create a dispersed flow (e.g., an annular dispersed flow). The dispersed flow then passes through a passive accelerator within the conduit, thereby greatly increasing the kinetic energy of the system. The accelerated flow is directed to collide with a rigid impact surface immediately downstream of the passive accelerator. This collision creates sufficient pressure to solubilize the carbon dioxide into the water. A retention network is provided at the output of the apparatus to collect and regulate the flow of carbonated water. 
         [0046]    In other embodiments, the carbonator may include other (non-“in line”) carbonator types. For example, some carbonators use carbon dioxide sprayed into a water container. Other carbonators employ a carbonating tank, called a saturator, and a high-pressure water pump. Carbonated water is produced by pressurizing the saturator tank with carbon dioxide and filling the tank with chilled water. Due to the high pressures resident in the saturator tank, typically around 70 psi, a relatively expensive high pressure water pump may be required to inject water into the tank. Furthermore, under the conditions in the saturator tank, the carbon dioxide takes time to dissolve into to the water and achieve a palatable level of carbonization. Accordingly, the saturator is typically large enough to hold a ready supply of carbonated water for dispensing and does not create new carbonated water instantaneously on demand. To maintain this supply, two or more sensors—and associated electronic controls—are typically used to start the high pressure pump and inject water into saturator when the level of carbonated water in the saturator falls below a set threshold and then stop the water injection when the tank fills to an appropriate level. 
         [0047]    In some embodiments, the carbonated water source  101  may selectively dispensed chilled carbonated water or chilled non-carbonated (“still”) water, e.g., by selective delivery of carbonating gas to an inline carbonator, as described in detail in Application No. 61/600,451 incorporated by reference above. 
         [0048]    In some embodiments, the water source  102  may be an unchilled water source. In some embodiments, the water source  103  may be a heated water source. 
         [0049]    In various applications, one or more of the water sources  101 ,  102 , and  103  may output water flows with certain unwanted characteristics including, e.g., an overly high flow rate, unwanted turbulence, spattering, etc. The flow dispenser  200  receives the flows from the water sources  101 ,  102 , and  103 , and conditions the flow to eliminate or reduce one or more unwanted characteristics. For example, the flow dispenser  200  may condition the flow to have a different (e.g. lower) flow rate, less turbulence (e.g., corresponding to a more laminar flow), less spattering., etc. 
         [0050]      FIGS. 2A-2I  show views of an embodiment of flow dispenser  200 . The flow dispenser  200  is made up of three main components, an upper housing  201 , a lower housing  202 , and a nozzle  203 . In other embodiments, the dispenser  200  may be made of more or fewer components. The components may be assembled using any know technique to provide a watertight fit. For example, bolts or other fasteners may pass through holes in the upper housing  201  into the lower housing  202  to secure the components together. The nozzle  203  may be welded to the lower housing  202 , e.g., using spin welding techniques known in the art. The nozzle  203  may include one or more energy directing features such as a shear joint  204  to facilitate welding. In various embodiments, other assembly techniques may be used including gluing, mechanical attachment, etc. 
         [0051]    The upper housing includes three inlets, a hot water inlet  205  (for connection to the hot water source  103 ), a chilled water inlet  206  (for connection to selective chilled carbonated/still water source  101 ), and an unchilled water inlet  207  (for connection to the unchilled water source  102 ). In some embodiments, the dispenser  200  includes fewer or additional inlets, e.g., a fourth inlet (not shown) to allow flavor content (e.g., a flavored syrup) to be delivered and mixed with the water flow through the dispenser  200 . 
         [0052]    Water received by each inlet passes through a respective check valve  208  into an interior chamber  209  of the dispenser  200 . As shown, each of the inlets  205 ,  206 ,  207  feature an L-shaped bend. However, in various embodiments, any other bend angle, multiple bends, no bends, or any other suitable shape may be used. 
         [0053]    The check valves may be mounted between check valve holders formed in the upper housing  201  and check valve retaining ribs  210  in the lower housing  202 . In other embodiments, the valves may be secured using any other suitable attachment. In some embodiments, the check valve  208  for each inlet be identical or different (e.g., to provide differential flow control). In some embodiments, one or more of the check valves  208  may be omitted. In some embodiments, other types of valves may be used, including, for example controllable (e.g., solenoid) valves which can be controlled by a controller to interrupt or regulate the flow through each inlet. In some embodiments, a check valve similar to  208  is used in the converging nozzle  203 . 
         [0054]    The chamber  209  acts as expansion chamber, such that the flow from the inlets  205 ,  206 ,  207  experiences an increased cross sectional area at the transition from the inlets to the chamber. This may advantageously condition the flow, e.g., by reducing pressure, flow rate, spattering, turbulence, etc. For example, in some embodiments, a high pressure, turbulent, non-constant (spattering) flow of carbonated water enters through inlet  206 . The flow expands and strikes the interior walls of the chamber. The pressure and flow rate is reduced. Water from the chamber drains out through the nozzle with a desired flow rate, reduced pressure, reduced spatter, and more laminar flow. 
         [0055]    In some embodiments, the chamber  209  has a tapered shape with a wider portion near the inlets  205 ,  206 , and  207  and a narrow portion near the nozzle  203 . In some embodiments, the chamber  209  may include one or more vapor exhaust ports to allow gas or vapor displaced by the inflow of water to exit the chamber. 
         [0056]    As shown, the nozzle  203  may be a converging nozzle. In various embodiments, the convergence of the nozzle may be fixed (as shown) or adjustable. In other embodiments the nozzle may be of any other suitable type, e.g., diverging, converging-diverging, etc. The nozzle  204  may contain one or more valves (e.g. a check valve, a shut off valve, or a control valve) or one or more filters. 
         [0057]    In some embodiments, the dispenser  200  includes a holder  211  for the UV light which directs light onto the water entering, flowing through, or exiting the dispenser. The UV light operates to disinfect or otherwise clean the water. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses in the water, the genetic material or the organisms&#39; DNA/RNA is rearranged and they can no longer reproduce, reducing or eliminating the risk of disease. UV-rays are energy-rich electromagnetic rays that are found in the natural spectrum of the sunlight. They are in the range of the invisible short wave light having a wavelength ranging from 100 to 400 nm. The UV light may provide UV doses in the range of, e.g., 1000-500,000 microwatt seconds per square centimeter, or any suitable subrange thereof. Such doses have been recognized as effective for reducing or eliminating water born contaminates. 
         [0058]    In some embodiments, the flow dispenser  200  includes a facility  210  (as shown a twist and lock connector with an O-ring groove) which allows for attachment of one or more peripheral devices. The peripheral device may include a device for mixing flavor content with the dispensed water stream, e.g., as described in Application No. 61/500,500 incorporated by reference above. In other embodiments, the peripheral device may be a container to be filled with the dispensed water. 
         [0059]    The flow dispenser  200  may include a visible light source holder  212  which holds a light source (e.g., an LED which outputs visible light) to illuminate the region below the nozzle  203 . 
         [0060]    The flow dispenser  200  may include a vapor outlet tube holder  214 , which holds a vapor (or other gas) outlet tube from one or more components of the system  100 . For example, the hot water source  103  may include a hot water tank, and the outlet tube may be used to exhaust steam from the tank. 
         [0061]    The flow dispenser may be made of any suitable material. In some embodiments, one or more of the upper and lower housings and nozzle are formed from or include a plastic (e.g., a thermoplastic) or polymer material (e.g., ABS, PP, PE, Acetal, PFTE, PV, PU, nylon, etc.), a metal (e.g., copper, bronze, iron, steel, stainless steel, etc.), a composite, etc. The components may be fabricated using any suitable technique including, e.g., molding (e.g., injection molding), machining (e.g., using one or more computer numerical controlled “CNC” tools such as a mill or lathe), etc. 
         [0062]    Any suitable connection may be used to attach the flow dispenser  200  to the water sources  101 ,  102 , and  103 . The connection may be permanent (e.g., glued) or detachable (e.g., using threaded connections). Any threaded connections may be national pipe thread tapered thread (NPT) or national pipe thread tapered thread fuel (NPTF) standard connections. In some embodiments, the threaded connections provide leak proof fittings mechanically, without the need for Teflon thread tape or similar applications. 
         [0063]    The examples described above are presented with reference to providing a flow dispenser for a flow of carbonated water. However, as will be understood by one skilled in the art, the devices and techniques described herein may be applied to provide flow dispensing for any suitable fluid flow, including any suitable mixed flow of liquid and gas. 
       Flavor Adapter and Flavor Pack 
       [0064]    FIGS.  3  and  4 A- 4 C illustrate a flavor adaptor  1100  which receives a flavor pack  1200 . The flavor adaptor  1100  includes an upper housing  1101  and a lower housing  1102  attached with a hinge  1103 , e.g., a pivot hinge. The hinge  1103  may be of any suitable type, including a spring loaded hinge. In some embodiments, the hinge opens and remains in a fully opened position, but snaps shut to a closed position when the upper housing  1101  is moved towards the lower housing  1102  past a threshold position. 
         [0065]    The adaptor  1100  also includes a release button  1104  which locks and unlocks the upper and lower housings  1101 ,  1102  together. The release button  1104  may use any type of locking mechanism known the art, including a spring latch, cam lock, etc. The locking mechanism may be mechanical, hydraulic, magnetic, electrical, or any other type. 
         [0066]    The upper housing  1101  includes a connector  1105  for connecting the adaptor  1100  to a water dispenser outlet. As shown, the connector  1105  is a twist and lock connector which includes a twist and lock slot  1106  and a coupling and sealing surface  1107  which provides a water tight connection with the dispenser. However, in other embodiments, any other suitable connector type may be used, including, e.g., a threaded connector such as national pipe thread tapered thread (NPT) or national pipe thread tapered thread fuel (NPTF) standard connection, In some embodiments, the threaded connections provide leak proof fittings mechanically, without the need for Teflon thread tape or similar applications. 
         [0067]    The upper housing provides an inlet  1108  which directs a flow of water from the dispenser through the upper housing  1101  to the flavor pack  1200 . In some embodiments, the inlet  1108  may include one or more piercing members which, when the adaptor  1100  is closed with flavor pack  1200  in place, pierce through a seal on the flavor pack  1200  to allow water flow from the inlet  1108  into the interior of the flavor pack. The piercing member may include one or more sharp edges or pointed features. 
         [0068]    The lower housing  1102  receives the flavor pack  1200  and includes a flavor cup positioning lever  109  to properly align the pack  1200  prior to closing the adaptor  1100 . The positioning lever  1109  (also referred to as a retaining lever) may be spring loaded, and may clamp down on one or more tabs or other features on the flavor pack  1200  to retain the pack in place. In some embodiments, the lever  1109  may share a common pivot hinge with the upper and lower housings  1101 ,  1102 . In other embodiments, any other suitable positioning or alignment device may be used, including mechanical devices (e.g., latches, locks, tabs/slots), hydraulic devices, pneumatic devices (e.g., using vacuum or positive pressure to retain the pack), magnetic devices, etc. 
         [0069]    The lower housing  1102  includes an outlet  1110  that allows water to flow from an outlet of the flavor pack  1200 . In some embodiments, the outlet  1110  may include one or more piercing members that, when the adaptor  1100  is closed with flavor pack  1200  in place, pierces through a seal on the flavor pack  1200  to allow water mixed with flavor to flow from the interior of the flavor pack out through the outlet  1110 . The piercing member may include one or more sharp edges or pointed features. 
         [0070]    As shown the water inlet  1108  is aligned with the center of the flavor pack while the outlet  1110  is positioned off center. However, in various embodiments this configuration may be reversed, or any other suitable configuration may be used. 
         [0071]    The lower housing  1102  includes a recess  1111  which receives a thumb tab  1201  on the flavor pack  1200  for removal of the pack after use. In various embodiments, the adaptor  1100  may include any other suitable mechanism or facility for removal or ejection of the spent flavor pack  1200  including, e.g., mechanical devices (e.g., levers, tabs, springs, etc.), hydraulic devices, pneumatic devices (e.g., using vacuum or positive pressure to eject the pack), magnetic devices, etc. 
         [0072]      FIGS. 5A-5C  show an exemplary embodiment of flavor pack  1200 .  FIG. 5A  shows the top side of the pack  1200  (e.g., the side designed to face the upper housing  1101  of the adaptor  1100 ). The top side includes a pack inlet  1202  sealed with a inlet film  1203 . As shown, the film  1203  is peeled back for illustrative purposes only. In practice, the inlet  1202  is sealed with the inlet film  1203  which remains in place until the adaptor  1100  closes around the pack  1200 , at which time the inlet  1108  of the adaptor  1100  pierces the film  1203  allowing water flow into the interior of the pack  1200 . 
         [0073]    The inlet  1100  may include any suitable features used to control or direct the flow of water. As shown, the inlet includes a capped tapered section having slots which tend to direct the inlet water from the central portion of the pack  1200  towards the periphery of the pack  1200  (see  FIG. 4C ). 
         [0074]      FIG. 5B  shows the bottom side of the pack  1200  (e.g., the side designed to face the lower housing  1102  of the adaptor  1100 ). The bottom side includes a pack outlet  1204  sealed with a outlet film  1205 . As shown, the film  1205  is peeled back for illustrative purposes only. In practice, the outlet  1204  is sealed with the inlet film  1203  which remains in place until the adaptor  100  closes around the pack  1200 , at which time the outlet  1110  of the adaptor  1100  pierces the film  1205  allowing water mixed with flavor flow out from the interior of the pack  1200  through the pack outlet  1204 . 
         [0075]    As shown, the bottom film  1205  extends beyond the pack outlet  1205  to seal the entire bottom of an inverted top cup member  1206 . In some applications, this configuration is advantageous as it reduces the number of parts, limits the amount of materials required, and reduces the assembly effort in constructing the pack  1200 . The pack  1200  may be made up of only the top cup member  1206  (e.g., formed using a single injection molding or stamping step) sealed with the bottom film  1205  and the top film  1204 . 
         [0076]      FIG. 5C  shows a view of the bottom of the flavor pack  1200  with the film  1205  removed for illustrative purposes only. Arrows indicate the flow path of water through the interior of the pack. 
         [0077]    The interior of the pack  1200  includes flavor content  1209  which mixes with the inflowing water to produce a flavored beverage. Flavor may take a number of forms including liquid (e.g., a syrup), soluble or insoluble solids (e.g., powders, tea leaves, coffee grounds, etc.). Flavored beverages include cold beverages (e.g., flavored soda, fruit flavored drinks, etc.) or hot beverages (e.g., coffee, tea, hot cocoa). In some embodiments, prior to being unsealed, the interior of the pack  1200  may be evacuated or filled with an inert gas or other substance, e.g., to maintain freshness of the flavor content  1209 . 
         [0078]    Water flows in through the inlet  1202  and is directed from the central portion of the pack  1200  towards the periphery of the pack  1200 , mixing with the flavor content. The mixed flavored beverage then exits the pack  1200  through the pack outlet  1204 . 
         [0079]    As shown, the cup member  1206  includes irrigation channels  1210  located around its peripheral edge (e.g., proximal the where the cup member seals with the bottom film  1205 ). The irrigation channels provide a more thorough and a homogeneous mixing and a more effective flavor extraction before flavored beverages are dispensed through the pack outlet  1204 . 
         [0080]    In some embodiments, the adaptor  1100  and/or the pack  1200  may include one or more filters. One or more of the inlets and outlets of the adaptor  1100  and/or the pack  1200  may include a valve, e.g., a check valve which allows only one way flow. 
         [0081]    The adaptor  1100  and pack  1200  may be made of any suitable material. In some embodiments, one or more components of the devices are formed from or include a plastic (e.g., a thermoplastic) or polymer material (e.g., PFTE, PV, PU, nylon, etc.), a metal (e.g., copper, bronze, iron, steel, stainless steel, etc.), a composite, etc. The components may be fabricated using any suitable technique including, e.g., molding (e.g., injection molding), machining (e.g., using one or more computer numerical controlled “CNC” tools such as a mill or lathe), etc. The sealing films  1203  and  1205  on the flavor pack  1200  may be made of any suitable material, including a plastic, a foil, etc. 
         [0082]    Some embodiments include a method of preparing a flavored beverage including attaching the flavor adaptor  1100  to a water dispenser, inserting the flavor pack  1200  into the flavor adaptor  1100 , and closing the adaptor  1100 , which may break one or more seals on the pack  1200 . The method includes establishing a flow of water from the dispenser, through the inlet  1105  of the adaptor  1100 , through the pack inlet  1202  into the interior of the flavor pack  1200  to mix with the flavor content  1209 , and then out through the pack outlet  1204  and adaptor outlet  1110  to provide a flavored beverage. 
         [0083]    In various embodiments any suitable water dispenser may be used including dispensers for chilled, unchilled (e.g., room temperature), and heated water. Some water dispensers dispense carbonated water. Water dispensers can include a reservoir or a pressurized source. Water dispensers may be stand alone devices, or incorporated into an appliance such as a refrigerator. In some embodiments, the dispenser may be of the type described in Provisional Patent Application No. 61/600,451 incorporated by reference above. 
         [0084]    With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art can translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity. 
         [0085]    It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. 
         [0086]    However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). 
         [0087]    Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.), In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc). 
         [0088]    It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.” 
         [0089]    The foregoing description of illustrative embodiments has been presented for purposes of illustration and of description. It is not intended to be exhaustive or limiting with respect to the precise form disclosed, and modifications and variations are possible in light of the above teachings or may be acquired from practice of the disclosed embodiments. It is intended that the scope of the invention be defined by the claims appended hereto and their equivalents.
