Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is a continuation of U.S. Provisional Patent Application No. 63 / 356,678 filed on June 29, 2022, which is incorporated herein by reference in its entirety.

[0003] background

[0004] The present disclosure relates generally to a beverage dispensing system and, more particularly, to a mechanical beverage dispensing system for producing and dispensing carbonated beverages.

[0005] Carbonated and / or flavored water beverages have become an increasingly popular choice for many people who want to drink more water. In many cases, carbonated and flavored water beverages are sold to consumers in the form of pre-mixed packaging, or cans or bottles. Traditionally packaged carbonated and flavored water beverages may be inconvenient to replenish, usually requiring consumers to travel to stores to purchase, and further requiring a large amount of space in consumer home refrigerators. Recently, home carbonation units and beverage dispensers have become desired alternatives to canned or bottled carbonated and flavored water beverages; however, many currently available home carbonation units and beverage dispensers have large floor space (e.g., occupying valuable space in consumer homes), require external power to cool and / or dispense beverages, and require users to manually add and mix additives, such as flavorings. In addition, many currently available home carbonation units and beverage dispensers require users to make large "batches" of carbonated and flavored beverages (e.g., one to two liters each time), and therefore lack the ability to produce carbonated and flavored water beverages as needed and at the convenience of the user.

[0006] Overview

[0007] One implementation of the present disclosure is a mechanical beverage dispensing system. The system includes a first tank for containing a first fluid; a second tank fluidly coupled to the first tank; a carbonator accessory adapted to be connected to a carbon dioxide (CO2) tank; a valve positioned on an outlet of the second tank and configurable between an open position and a closed position; an actuator mechanically coupled to the valve and configured to actuate the valve between an open position and a closed position when a user physically manipulates the actuator; a pump for transferring the first fluid from the first tank to the second tank when the valve is in the open position; a first compressed CO2 passage from the carbonator accessory to the pump, the pump configured to operate by compressing CO2 gas ; a second compressed CO2 passage from the carbonator accessory to a second tank, the first fluid being carbonated by compressed CO2 gas in the second tank; an additive cartridge tank sized to receive one or more additive packages containing one or more additives; and a mixing chamber including a mixing area and an outlet, the additive cartridge tank being in fluid communication with the mixing chamber, the mixing area being adapted to receive the carbonated first fluid from the second tank and the one or more additives from the additive cartridge tank when the valve is in an open position, and wherein the outlet is configured to dispense a beverage comprising a mixture of the first fluid and the one or more additives.

[0037] Referring generally to the accompanying drawings, according to various embodiments, a mechanical beverage dispensing system is shown. The mechanical beverage dispensing system described herein may include a first tank for containing a fluid (e.g., water or other diluent) and a carbonation system. In some embodiments, the carbonation system includes a second "carbonation tank" in which the fluid is carbonated. A pump powered by carbon dioxide (CO2) may be used to transfer the fluid through the system. For example, a pump may transfer the fluid from the first tank to the second tank for carbonation of the fluid. Alternatively, the system includes a series carbonation system that also operates only with CO2 power. The system may be partially controlled by a mechanical switch (i.e., an actuator) that is manipulated by a user so that when the mechanical switch is pressed, the carbonated fluid flows out of the second tank or the carbonation system and flows into a mixing chamber where it is mixed with one or more additives (e.g., flavorings).

[0038] Unlike other household carbonation units and beverage dispensers as discussed above, the mechanical beverage dispensing system described herein is completely mechanical and therefore does not require an external power source. For example, no electricity is required to operate the pump, but rather fluids are conveyed throughout the system, and additives are dispensed using compressed CO2 and / or the mechanical action of an actuator. The size of the mechanical beverage dispensing system can be determined to fit in a standard residential refrigerator so that the fluid (e.g., water) is maintained at a cooled temperature, rather than requiring a separate or built-in refrigeration unit. Accordingly, the mechanical beverage dispensing system described herein can be more energy-efficient and compact than existing household carbonation units and beverage dispensers.

[0039] In addition, as mentioned above, the mechanical beverage dispensing system can dispense additives (e.g., flavorings, vitamins, minerals, electrolytes, etc.) from replaceable or refillable additive cartridges. In this way, the system can produce enhanced (e.g., flavorings, vitamin enhancements, etc.) carbonated beverages on demand with minimal user input. In various implementations, the additive cartridge is an unsweetened or non-nutritional sweetened additive, thereby ensuring a small (e.g., 12 ounces or less, 10 ounces or less, 8 ounces or less, 5 ounces or less, 3 ounces or less, 1 ounce or less) cartridge size. By providing a small cartridge size, the mechanical beverage dispensing system can dispense a variety of different enhanced beverages (e.g., lemon-flavored bubble water, vitamin-enhanced bubble water, etc.). These replaceable or refillable additive cartridges also have the following advantages: use a smaller package than premixed beverages, thereby reducing waste, reducing transportation-induced costs and emissions, and allowing users to obtain greater customization options. The other features and advantages of the mechanical beverage dispensing system are described in more detail in the example provided below.

[0040] Overview

[0041] Overall reference Figures 1 to 5 , a block diagram of different configurations of a mechanical carbonated beverage dispensing system 100 is shown, according to various embodiments. As described above, the system 100 can generally be configured to produce carbonated beverages and additive-enhanced beverages on demand. The system 100 includes a first tank for containing a fluid, shown as a fluid tank 102. Typically, the fluid is water; however, the fluid tank 102 can be configured to contain other fluids, such as coffee, tea, juice, etc. Accordingly, the fluid tank 102 can be constructed of any food-safe or food-grade material, such as metal, glass, or plastic. In some embodiments, the fluid tank 102 is transparent or translucent so that a user can view the liquid level of the fluid contained in the fluid tank 102 (e.g., as shown in FIG. 1 ). Figure 7 102). In other embodiments, the fluid tank 102 can include an indicator for displaying a fluid level. In some embodiments, the fluid tank 102 includes a selectively removable or openable lid or cover (not shown) that, when opened or removed, provides an opening for filling the fluid tank 102 with fluid. In some embodiments, the fluid tank 102 can be removably coupled to the system 100 (e.g., coupled to a downstream component of the system 100) such that the fluid tank 102 can be removed from the system 100 to be filled with fluid.

[0042] In certain embodiments, fluid tank 102 includes a filter 104 for filtering fluid. Filter 104 can be, for example, an activated carbon filter. In certain embodiments, filter 104 is positioned inside fluid tank 102 and at its outlet. Alternatively, filter 102 is positioned on a first fluid conduit 106 extending from the outlet of fluid tank 104 to pump 108. As described herein, first fluid conduit 106 can be any suitable pipeline or conduit for transporting fluid. For example, first fluid conduit 106 can be a flexible food grade plastic pipeline (for example, polyurethane, nylon, PVC, etc.). First fluid conduit 106 is usually connected to the outlet (for example, using any suitable connector or fittings) of fluid tank 102 at the first end and is connected to the inlet of pump 108 at the second end.

[0043] Typically, pump 108 is powered by compressed CO2 rather than electricity. As shown, compressed CO2 can be delivered to pump 108 via a first compressed CO2 passage 112, which extends from a CO2 cylinder 110 to pump 108. Accordingly, the first compressed CO2 passage 112 can be formed by any material capable of accommodating compressed gas, such as aluminum or steel pipe. In some embodiments, a first pressure regulator 116 is positioned on (i.e., interrupted) the first compressed CO2 passage 112 to regulate and / or control the pressure of the compressed CO2 provided to pump 108. In other words, the operation of pump 108 can be controlled by the first pressure regulator 116. In other embodiments, the first pressure regulator 116 is integrated into the pump 108, rather than being positioned as a separate component on the first compressed CO2 passage 112. In some embodiments, the first pressure regulator 116 is set to 90psi or operates at 90psi.

[0044] The system 100 is shown as further comprising a carbonation system 120, which is fluidly coupled to the pump 108 and thereby to the fluid tank 102, such that the carbonation system 120 receives a fluid (e.g., water) from the fluid tank 102. Typically, the fluid can be infused with CO2 (i.e., carbonated) provided via a second compressed CO2 passage 114, which extends from the CO2 cylinder 110 to the carbonation system 120. The second compressed CO2 passage 114 can be formed of any material capable of accommodating compressed gas, such as aluminum or steel tubing. In some embodiments, a second pressure regulator 118 is positioned on (i.e., interrupts) the second compressed CO2 passage 114 to regulate and / or control the amount of compressed CO2 provided to the carbonation system 120. In other embodiments, the second pressure regulator 118 is integrated into the carbonation system 120. In some embodiments, the first pressure regulator 116 is set to or operated at 72.5 psi.

[0045] In some embodiments, the carbonation system 120 is an inline carbonator or inline carbonation system. In other words, the fluid flows from the fluid tank 102 and passes through the carbonation system 120 to be carbonated. The inline carbonation system allows the fluid to be carbonated continuously or on demand. Figure 6 102, the carbonation tank 102 may be constructed of any food safe or food grade material, such as metal, glass, or plastic. In some embodiments, the carbonation tank is transparent or translucent so that a user can view the level of the fluid contained in the carbonation tank. In other embodiments, the carbonation tank may include an indicator for displaying the fluid level. Figure 7 To provide additional description of the carbonation system 120 in an implementation having a carbonation tank.

[0046] Now go to Figure 1 , specifically, a first configuration of the system 100 is shown, the first configuration including a second fluid conduit 122 formed of food grade tubing (e.g., aluminum, polyurethane, nylon, PVC, etc.) extending from the carbonation system 120 to the mixing valve 124, thereby fluidly coupling the carbonation system 120 to the mixing valve 124. In some embodiments, the system 100 may include a plurality of second fluid conduits 122 extending from the carbonation system 120 to a single mixing valve 124 or to one or more separate mixing valves 124 (e.g., each mixing valve corresponds to one of the plurality of second fluid conduits 122). In some embodiments, the number of second fluid conduits 122 and / or mixing valves 124 corresponds to the number of slots in the additive cartridge slots 126, which are also fluidly coupled to the mixing valve 124. In other words, the system 100 may include a separate second fluid conduit 122 and / or mixing valve 124 for each additive cartridge 128.

[0047] Each additive cartridge 128 can contain one or more additives to mix with the fluid from the carbonation system 120. As described herein, "additives" can refer to any substance that can be mixed with a base liquid to produce an output fluid mixture. Additives can include, but are not limited to, flavor concentrates, sweeteners, acids, vitamins, probiotics, minerals, electrolytes, fibers, amino acids, proteins, dairy products (e.g., milk, cream, etc.), coffee concentrates, tea concentrates, juice concentrates, alcohol, medications, supplements, etc. In some embodiments, the form of the additive ensures full integration into the base liquid (e.g., liquid, gel, solution, suspension, colloid, etc.). The additive can be soluble or insoluble. In some embodiments, the additive cartridge 128 has at least one opening through which the contained additive is dispensed. In some embodiments, the additive cartridge 128 holds about two ounces of additives (e.g., in liquid form). In some embodiments, the additive cartridge 128 contains more than one additive in multiple "compartments" or spaces. Various examples of additive cartridges 128 having multiple ingredient compartments are discussed in U.S. Patent Application No. 2016 / 0318689, which is incorporated herein by reference in its entirety. Alternatively, each additive cartridge 128 may have a single chamber in which the additive is stored.

[0048] Also shown is a mechanical actuator 130 that is mechanically coupled to the mixing valve 124 via a linkage 132. Generally, the actuator 130 is configured to actuate the mixing valve 124 between an open position and a closed position in response to a user interaction (e.g., a user pushing or otherwise manipulating the mechanical actuator 130). In some implementations, a separate shutoff valve (not shown) can be positioned downstream of the mixing valve. The linkage 132 can be coupled to the shutoff valve such that actuation of the mechanical actuator 130 causes the shutoff valve to switch between an open position and a closed position. As an example, the actuator 130 is a button that includes a spring for holding the button in a first position (e.g., not pressed), but it should be understood that the actuator 130 can be any suitable actuator, lever, button, etc. that can actuate the mechanical actuator 130.

[0049] In some embodiments, the actuator 130 is mechanically coupled to one or both of the first pressure regulator 116 and the second pressure regulator 118 (e.g., via a separate linkage (not shown)) such that the pressure regulators 116, 118 operate in response to user input via the mechanical actuator 130. In some embodiments, the system 100 includes a plurality of mechanical actuators 130 (not shown), each coupled to a separate mixing valve 124 or a single common mixing valve 124. For example, the system 100 may include a separate actuator 130 corresponding to each of the additive cartridge tanks 126. In this manner, each actuator 130 may cause a different additive to be dispensed.

[0050] In order to make the system 100 produce and distribute carbonated and additive-enhanced beverages (hereinafter generally referred to as "mixed" beverages), the user can interact with the actuator 130 (e.g., by pressing the mechanical actuator 130) to open the mixing valve 124 or the downstream stop valve. Then, the carbonated fluid (e.g., water) can flow out / flow through the carbonation system 120, pass through the mixing valve 124 and flow to the outlet of the system 100, where the carbonated fluid is distributed into a container 134 (e.g., a bottle or a glass). When the carbonated fluid passes through the mixing valve 124, the additive is extracted from one or more additive cartridges due to the Venturi effect. In other words, the mixing valve 124 can be a Venturi valve. Specifically, the mixing valve 124 can have a middle portion with a diameter less than the two ends, so that the flow rate of the carbonated fluid passing through the mixing valve 124 increases at the middle portion. This increased flow rate forms a low pressure area in the middle portion of the mixing valve 124, which can extract additives from the one or more additive cartridges 128. As the additive is dispensed, it can mix with the carbonated fluid before reaching the outlet of the system 100 and being dispensed into the container 134. In some embodiments, the system 100 can further include a downstream mixing chamber (e.g., Figure 4 and Figure 5 ), the combined carbonated fluid and additives are further mixed in this downstream mixing chamber prior to dispensing.

[0051] Before the mixed beverage is dispensed, or while the mixed beverage is being mixed and dispensed, the pump 108 can be activated (e.g., by the first pressure regulator 116) to transfer fluid from the fluid tank 102 to the carbonation system 120, where the fluid is carbonated. For example, when the carbonation system 120 is or includes a carbonation tank, the pump 108 can be activated any time the fill level of the carbonation tank drops below a certain level.

[0052] Alternatively, when the carbonation system 120 is in series, the fluid can be carbonated on demand (e.g., only when the actuator 130 is pressed). In some embodiments, the pump 108 is automatically activated in response to a drop in pressure in the carbonation system 120 (e.g., due to the mixing valve 124 opening). In other embodiments, as described above, the actuator 130 is configured to operate one or both of the first pressure regulator 116 and the second pressure regulator 118 so as to activate the pump 108 and carbonate the fluid in the carbonation system 120. In still other embodiments, the fluid is continuously transferred from the fluid tank 102 to the carbonation system 120 until the carbonation tank is full (e.g., as determined based on the internal pressure of the carbonation tank). Alternatively, in some embodiments, the system 100 does not include the pump 108, and accordingly, the fluid is automatically transferred from the fluid tank 102 to the carbonation system 120 when the carbonation tank is emptied or to simply fill the carbonation tank. For example, the fluid may be gravity fed to the carbonation system 120. Reference is made below to Figure 6 to provide additional description of the pump 108 and carbonation system 120 in a series implementation.

[0053] Now go to Figure 2 , shows an alternative configuration of the system 100 in which the actuator 130 is positioned at the outlet of the mixing valve 124. Alternatively, the actuator 130 can be positioned on the second fluid conduit 122 between the carbonation system 120 and the mixing valve 124. In this way, the actuator 130 can be a shutoff valve to selectively allow or prevent the carbonated fluid from flowing through the mixing valve 124, which in turn selectively allows or prevents the additive cartridge 128 from dispensing additive. It should be appreciated that the previously described configurations (e.g., Figure 1 ) are structured and operated as described above, and are not described separately for the sake of brevity. Figure 1 Describes in detail Figure 2 Elements 102-122 are shown in FIG.

[0054] In embodiments where the system 100 includes a plurality of second fluid conduits 122 and / or mixing valves 124, each of the plurality of second fluid conduits 122 and / or mixing valves 124 may include a separate mechanical actuator 130. For example, the system 100 may include three mixing valves 124, each corresponding to one of the three additive cartridges 128, and correspondingly including three mechanical actuators 130. Other numbers of mixing valves 124, additive cartridges 123, and mechanical actuators 130 may be used. In this manner, when a user interacts with the mechanical actuator 130 or one of the plurality of mechanical actuators 130, the carbonated fluid may be allowed to flow through the mixing valve 124, thereby causing the additive cartridge 128 to dispense the additive (e.g., due to a venturi effect). In turn, the pressure loss caused by the carbonated fluid flowing out of the system 100 (e.g., into the container 134) may cause the pump 108 to transfer additional fluid from the fluid tank 102 to the carbonation system 120, where the additional fluid is carbonated.

[0055] Figure 3 Another alternative configuration of the system 100 is shown, in which an additive cartridge slot 126 and an additive cartridge 128 contained therein replace the mixing valve 124 and the mechanical actuator 130. Specifically, each of the additive cartridges 128 can independently act as a button or valve (e.g., functionally similar to the mechanical actuator 130) that can be pressed or otherwise manipulated by a user to cause mixing and dispensing of a mixed beverage. Specifically, in some such embodiments, each additive cartridge 128 can be positioned in a linear actuation mount or holder of the additive cartridge slot 126 so that each additive cartridge 128 can be manipulated between a first position (e.g., not pressed or "up") that prevents carbonated fluid from flowing through the additive cartridge slot 126 or a second position (e.g., pressed or "down") that allows carbonated fluid to flow.

[0056] To this end, the additive cartridge 126 may include an inlet to which the second fluid conduit 122 is coupled and an outlet from which the mixed beverage is dispensed.

[0057] Alternatively, the outlet of the additive cartridge slot 126 can be fluidly coupled to a separate mixing chamber for mixing the combined carbonated fluid and the dispensed additive. In any case, the additive cartridge slot 126 can include a plurality of internal fluid passages through which the carbonated fluid can flow, each internal fluid passage corresponding to one of the additive cartridges 128. In this manner, when a user presses or otherwise actuates one of the additive cartridges 128, the carbonated fluid can flow through the corresponding internal fluid passage of the additive cartridge slot 126, causing the additive to be dispensed from the additive cartridge 128 in the process. It should be appreciated that the previously described configurations (e.g., Figure 1) are structured and operated as described above, and are not described separately for the sake of brevity. Figure 1 Describes in detail Figure 3 Elements 102-122 are shown in FIG.

[0058] Reference now Figure 4 , shows yet another alternative configuration of the system 100 according to some embodiments. It should be understood that the previously described configurations (e.g., Figure 1 ) are structured and operated as described above, and are not described separately for the sake of brevity. Figure 1 Describes in detail Figure 4 102 to 122 shown in FIG. 10. In this configuration, system 100 is shown to include a mixing chamber 138 in fluid communication with carbonation system 120 via second fluid conduit 122. Mixing chamber 138 is further shown to be fluidly coupled to additive cartridge tank 126. In some embodiments, mixing chamber 138 includes a mixing area 140 in which the additive and carbonated fluid are mixed. In some embodiments, the mixing area includes a bowl, such as Fig. 10A and Fig. 10B As shown, it will be described in detail below.

[0059] The mixing chamber 138 may further include an outlet 142 from which the mixed beverage may be dispensed into the container 134. Figures 1 to 3 Any of the configurations described may include a mixing chamber 138 positioned downstream of the mixing valve 124 , the actuator 130 , or the additive cartridge 126 .

[0060] The second valve 136 interrupts the second fluid conduit 122 and thereby controls the flow of carbonated fluid to the mixing chamber 138. The second valve 136 may be actuated by the mechanical actuator 130 via the linkage 132 between an open position and a closed position.

[0061] Alternatively, the mechanical actuator 130 and the second valve 136 may be integrated together as a single unit and positioned on the fluid conduit 122. In the closed position, the second valve 136 may prevent carbonated fluid from flowing from the carbonation system 120 to the mixing chamber 138. In other words, the second valve 136 is a shutoff valve.

[0062] In some embodiments, the actuator 130 may also be mechanically coupled to the additive cartridge tank 126 via a linkage 133. In some such embodiments, the actuator 130 is further configured to cause one or more of the additive cartridges 128 to dispense the additive into the mixing chamber 138. In some embodiments, the system 100 includes a plurality of mechanical actuators 130, each corresponding to one of the additive cartridges 128. In some such embodiments, each of the plurality of mechanical actuators 130 may be coupled to the same second valve 136 or a separate second valve 136.

[0063] In some embodiments, the actuator 130 (e.g., via the linkage 133) applies a compressive force or causes the additive cartridge slot 126 to apply a compressive force to one or more of the additive cartridges 128. For example, the actuator 130 can manipulate the additive cartridge slot 126 to squeeze at least one additive cartridge 128, such as by contracting one or more side walls of the corresponding cartridge slot. In such embodiments, the additive cartridge 128 can be at least partially flexible so that when compressed, the additive is dispensed. For example, the actuator 130 can cause (e.g., via the linkage 133) a roller or plate to compress a portion of one of the additive cartridges 128. In another example, the actuator 130 can manipulate a plunger in the additive cartridge slot 126 to cause at least one of the additive cartridges 128 to dispense the additive.

[0064] In other words, in order to Figure 4 To dispense a mixed beverage in the configuration of the system 100 shown in FIG, a user may depress or otherwise manipulate the actuator 130, which in turn opens the second valve 136 via the linkage 132, thereby allowing the carbonated fluid to flow from the carbonation system 120 to the mixing chamber 138. At the same time, a mechanical force may be transmitted to the additive cartridge slot 126 via the linkage 132, which causes the additive cartridge slot 126 to apply a compressive force or other type of mechanical force to at least one additive cartridge 128. In turn, the additive cartridge 128 may dispense the additive into the mixing chamber 138, where the additive is mixed with the carbonated fluid and dispensed from the outlet of the mixing chamber 138 into the container 134.

[0065] Reference now Figure 5 , shows yet another alternative configuration of the system 100 according to some embodiments. It should be understood that the previously described configurations (e.g., Figure 1 ) are structured and operated as described above, and are not described separately for the sake of brevity. Figure 1 Describes in detail Figure 5102-122 shown in FIG. 102-122. In this configuration, the actuator 130 is shown as being coupled to the third valve 138 via a linkage 135, so that the actuator 130 actuates the third valve 138 between an open position and a closed position when manipulated by a user. The third valve 138 is also shown as being positioned on (i.e., interrupting) the third compressed CO2 passage 115, which extends from the CO2 cylinder 110 to the additive cartridge tank 126. In this way, compressed CO2 from the CO2 cylinder 110 can be provided to the additive cartridge tank 126 so that the additive cartridge tank 126 dispenses one or more additives. As an example, the actuator 130 can cause both the second valve 136 and the third valve 138 to move from a closed position to an open position in response to user input. The compressed CO2 then flows to the additive cartridge tank 126 to pressurize the additive cartridge tank 126 and / or pressurize a specific additive cartridge 128 contained in the additive cartridge tank 126. This pressure on the at least one additive cartridge 128 causes the cartridge to dispense the additive into the mixing chamber 138. Simultaneously, carbonated fluid flows from the carbonation system 120 into the mixing chamber 138 where it is mixed with the additive before being dispensed.

[0066] Series Carbonation

[0067] As described above, the carbonation system 120 can be configured for batch carbonation or series carbonation. In a batch carbonation configuration, the carbonation system 120 generally includes a carbonation tank in which the fluid is helpful and one or more devices (e.g., a carbonated stone) for injecting CO2 into the carbonation tank and / or the fluid. Typically, batch carbonation requires that a predetermined volume of fluid be provided to the carbonation tank, in which the entire volume is carbonated and stored until distribution. However, in a series carbonation configuration, the fluid is carbonated on demand. For example, when the fluid passes through the carbonation system 120, only a portion of the fluid (e.g., a portion) is carbonated, and the carbonated fluid is not stored but distributed. Accordingly, compared to, for example, a device with a carbonation tank, series carbonation can allow more precise carbonation control (e.g., to meet a specific carbonation level) and a smaller form factor.

[0068] Reference now Figure 6 , shows a detailed diagram of the carbonation system 120 in the above-described series configuration according to some embodiments. As in the various configurations described above, Figure 6The configuration shown includes a fluid tank 102, a pump 108, a CO2 cylinder 118, a first pressure regulator 116 and a second pressure regulator 118, and first and second compressed CO2 passages 112, 114. For the sake of brevity, these components are not described in detail. However, the fluid tank 102 is roughly shown as being connected to the pump 108 via the first fluid conduit 106. As described above, the pump 108 is typically operated (i.e., powered) by compressed CO2 (e.g., as opposed to electricity). Accordingly, compressed CO2 can be provided to the pump 108 via the first compressed CO2 passage 112.

[0069] In some embodiments, the first pressure regulator 116 controls (i.e., regulates) the pressure of the CO2 provided via the first compressed CO2 passage 112. For example, the first pressure regulator 116 can maintain the pressure of the CO2 in the first compressed CO2 passage 112 at 90psi or about 90psi. In some embodiments, the CO2 cylinder 110 can be first connected or directly connected to the first pressure regulator 116, as shown. In other embodiments, the CO2 cylinder 110 is connected to the first pressure regulator 116 via a separate compressed CO2 passage, via a connector, etc. As shown, in some embodiments, the second pressure regulator 118 is positioned downstream of the first pressure regulator 116. For example, the second pressure regulator 118 is connected to the first compressed CO2 passage 112 (e.g., via a t-shaped fitting). In other embodiments, the second pressure regulator 118 is directly coupled to the CO2 cylinder 110, or an additional compressed CO2 path may extend from the CO2 cylinder 110 to the second pressure regulator 118, such that the first pressure regulator 116 and the second pressure regulator 118 independently regulate the pressure of the CO2 received from the CO2 cylinder 110. It should be understood that all such possible arrangements of the first pressure regulator 116 and the second pressure regulator 118 are contemplated herein.

[0070] In some embodiments, the first pressure regulator 116 may be configured for or set to a higher pressure than the second pressure regulator 118. For example, the first pressure regulator 116 may be set to 90 psi, while the second pressure regulator 118 is set to 72.5 psi. In some embodiments, the first pressure regulator 116 and / or the second pressure regulator 118 may be adjustable to control the pressure of the CO2 provided from the CO2 cylinder 110. For example, the first pressure regulator 116 may be adjustable to control the speed of the pump 108 and thereby control the flow rate of fluid through the carbonation system 120.

[0071] Looking more closely at the carbonation system 120, the pump 108 may optionally be coupled to a pulsation dampener 604 that reduces fluid pulsations caused by the pump 108 and ensures a steady flow of fluid to the rest of the carbonation system 120. For simplicity, the pump 108, the pulsation dampener 604, and the remaining components of the carbonation system 120 are described herein as components of the fluid pathway 602. However, it should be appreciated that each component (e.g., the pump 108, the pulsation dampener 604, etc.) or group of components may be fluidly coupled via a separate fluid conduit (e.g., similar or identical to the first fluid conduit 106). For example, the pump 108 may be coupled to the pulsation dampener 604 via a length of tubing or other type of fluid conduit.

[0072] In some embodiments, the fluid pathway 602 includes a check valve 606 that prevents fluid from flowing back into the pulsation dampener 604 and / or the pump 108. Optionally, the fluid pathway 602 also includes a pressure relief valve 608, which is a safety feature to prevent over-pressurization of the carbonation system 120. In some embodiments, the pressure relief value 608 is set to or configured for a pressure similar to the pressure of the first pressure regulator 116 and / or the pressure provided by the pump 108 as described below. For example, if the first pressure regulator 116 is set to 90 psi, the pressure relief value 608 can be configured to release at 100 psi. Typically, the pressure relief value 608 is selected or set to a pressure within about 10% of the first pressure regulator 116. In some embodiments, the fluid pathway 602 further includes a check valve 610, which is positioned after the pressure relief valve 608 (i.e., "downstream") to prevent backflow.

[0073] Carbonation system 120 is shown as further comprising a first venturi injector 612 and optionally a second venturi injector 614. The first venturi injector 612 and the second venturi injector 614 (also referred to as a venturi-vortex injector) are configured to inject CO2 into the fluid as the fluid passes through each injector. In other words, the first venturi injector 612 and the second venturi injector 614 can use the venturi effect produced by the fluid flowing through the first venturi injector 612 and the second venturi injector 614 to mix CO2 with the fluid, thereby carbonating the fluid. As shown, the first venturi injector 612 and the second venturi injector 614 can be positioned in series so that the fluid flows through the first venturi injector 612 before flowing through the second venturi injector 614, thereby increasing the carbonation of the fluid. As shown, each of the first venturi injector 612 and the second venturi injector 614 can be coupled to the second pressure regulator 118 via the second CO2 passage 114 or another CO2 passage. In this way, both the first venturi injector 612 and the second venturi injector 614 are fed with CO2 at a pressure (e.g., 72.5 psi) specified by the second pressure regulator 118. However, it should be appreciated that the first venturi injector 612 and the second venturi injector 614 can alternatively be coupled to the first pressure regulator 116 or another separate pressure regulator.

[0074] Continuing downstream of the first venturi injector 612 and the second venturi injector 614, the carbonation system 120 may include a first filter 616 and operatively include a second filter 618. In some embodiments, the first filter 616 and the second filter 618 are dynamic membrane filters. In some such embodiments, the first filter 616 and the second filter 618 may be glass bead filters. It should be appreciated that the first filter 616 and the second filter 618 may be used for a variety of purposes: both for filtering the fluid passing through the fluid passage 602 and for dispersing or "breaking up" the CO2 injected by the first venturi injector 612 and the second venturi injector 614. For example, mixing CO2 with the fluid through the first venturi injector 612 and the second venturi injector 614 may result in an uneven distribution of CO2 within the fluid, or "bubbles" of uneven and large size. Therefore, the first filter 616 and the second filter 618 may further merge the CO2 with the fluid, thereby producing smaller "bubbles" and a more uniform distribution of bubbles within the fluid, thereby increasing the rate at which CO2 dissolves into the fluid.

[0075] Carbonation system 120 is shown as further comprising first carbonate stone 620 and optionally second carbonate stone 622. First carbonate stone 620 and second carbonate stone 622 are generally configured to inject / dissolve additional CO2 into fluid. In this way, first carbonate stone 620 and second carbonate stone 622 can increase the carbonation of fluid. For example, first carbonate stone 620 and second carbonate stone 622 can "fine tune" the carbonation of fluid after the first venturi injector 612 and second venturi injector 614 initially inject CO2. For example, the bubbles formed by the CO2 injected by the first carbonate stone 620 and second carbonate stone 622 are smaller than the bubbles formed by the first venturi injector 612 and second venturi injector 614 and the first filter 616 and the second filter 618. Accordingly, it should be appreciated that the first and second carbonate stones 620 , 622 are generally positioned downstream of the first and second venturi injectors 612 , 614 and / or the first and second filters 616 , 618 .

[0076] By positioning the first carbonate stone 620 and the second carbonate stone 622 downstream of the first venturi injector 612 and the second venturi injector 614 and / or the first filter 616 and the second filter 618, an increased carbonation level is provided in the fluid. For example, the relatively small bubbles formed by the first carbonate stone 620 and the second carbonate stone 622 are not recombined with the larger bubbles from the first venturi injector 612 and the second venturi injector 614 and / or the first filter 616 and the second filter 618, which will reduce the rate of CO2 dissolving into the fluid by reducing the surface area contact between the CO2 bubble and the fluid. In other words, by positioning the first carbonate stone 620 and the second carbonate stone 622 downstream of other components, the CO2 bubble size continues to decrease, thereby increasing the rate of CO2 dissolving into the fluid. In some embodiments, the first carbonate stone 620 and the second carbonate stone 622 can include a t-shaped fitting or be integrated therein so that the fluid can pass through or bypass the first carbonate stone 620 and the second carbonate stone 622, while additional CO2 dissolves into the fluid. In some embodiments, the first carbonate stone 620 and the second carbonate stone 622 are 0.5 micron stones.

[0077] As described herein, the combination of the first and second venturi injectors 612, 614, the first and second filters 616, 618, and the first and second carbonate stones 620, 622 can result in an absolute carbonation level of about 3.1 volumes, which after mixing with additives (e.g., at the mixing valve 124, the mixing chamber 138, etc.) can produce about 2.6 volumes of carbonation in the dispensed beverage. It is worth noting that as the temperature of the fluid increases, it becomes increasingly difficult to dissolve CO2 into a fluid (e.g., water); therefore, Figure 6 The specific arrangement of the components shown in is very suitable for producing suitable carbonated beverages (e.g., absolute carbonation of about 2.6 volumes) at the higher temperatures (e.g., about 35°F to 38°F) of residential refrigerators, as discussed in more detail below. It should be appreciated that the various combinations of the first venturi injector 612 and the second venturi injector 614, the first filter 616 and the second filter 618, and the first carbonated stone 620 and the second carbonated stone 622 can obtain different carbonation levels. Accordingly, all such combinations of these components are considered herein. For example, the carbonation system can include one or both of the first venturi injector 612 and the second venturi injector 614, the first filter 616 and the second filter 618, and the first carbonated stone 620 and the second carbonated stone 622, and can include additional injectors, filters and carbonated stones in some cases.

[0078] In some embodiments, the carbonation system 120 may further include a static mixer 624 positioned after (i.e., downstream) the first carbonate stone 620 and the second carbonate stone 622. The static mixture 624 may further dissolve the CO2 injected into the fluid via the first venturi injector 612 and the second venturi injector 614 and the first carbonate stone 620 and the second carbonate stone 622. In some embodiments, the static mixer 624 may be omitted. A check valve 626 may be included after the static mixer 624 to prevent fluid backflow. Further, after the check valve 626, a flow compensation valve 628 may be included to set and / or maintain a stable flow of fluid from the carbonation system 120 to any downstream component of the system 100 (including the mixing valve 124, the mixing chamber 138, etc.). In some embodiments, the flow compensation valve 628 is manually set (e.g., by the user, during manufacturing, etc.) and / or adjusted. Finally, the carbonation system 102 is shown as including a valve 630 that controls the flow of fluid to the mixing valve 124, the mixing chamber 138, etc. In some embodiments, valve 630 is a ball valve. In some embodiments, valve 630 itself represents mixing valve 124.

[0079] Example Implementation

[0080] Reference now Figure 7 , a diagram showing an example implementation of a presentation system 100 according to some embodiments. Specifically, Figure 7 A side view of an exemplary configuration of the system 100 is shown with a translucent lower housing 702 to illustrate various internal components of the system 100. For example, the housing 702 is shown enclosing the CO2 cylinder 110, the first compressed CO2 passage 112, the first pressure regulator 116, the mixing chamber 138, and the additive cartridge tank 126. Figure 7 1, but the housing 702 also encloses the second compressed CO2 passage 114, the second pressure regulator 118, and the pump 108, which can be located on the opposite side of the system 100 from that shown (e.g., behind the CO2 cylinder 110). In addition, the housing 702 also encloses an accessory 704 to which the CO2 cylinder 110 is connected and from which the compressed CO2 is distributed to the entire gas system (e.g., the first compressed CO2 passage 112 and the second compressed CO2 passage 114, the first pressure regulator 116 and the second pressure regulator 118). Figure 7 Also illustrated is an outlet 706 of the system 100 , which is shown extending from and integral with the mixing chamber 138 .

[0081] in addition, Figure 7 Fluid flow through the system 100 during operation is shown. For example, prior to user input (e.g., to the actuator 130), fluid (e.g., water) stored in the fluid tank 102 is pulled (1) through the filter 104 (2) and into the carbonation tank 708 (e.g., the carbonation system 120 or a portion of the carbonation system 120). As described herein, the carbonation tank 708 is a container (e.g., similar to the fluid tank 102) configured to hold a volume of fluid (e.g., received from the fluid tank 102) into which compressed CO2 is injected to carbonate the fluid. Accordingly, once the carbonation tank 708 is filled with fluid (3), the fluid can be carbonated using compressed CO2 provided by the CO2 cylinder tank 110. In response to the user manipulating the actuator 130 (e.g., by pressing the actuator 130), the carbonated fluid in the carbonation tank 708 is released (4). As the carbonated fluid passes through additive cartridge slots 126 (e.g., before or upon reaching mixing chamber 138), the fluid flow "pulls" additives from one or more of the additive cartridges 128 (5). Within mixing chamber 138, the carbonated fluid and additives are mixed before being dispensed from outlet 706 (6).

[0082] Reference now Figure 8 , a diagram showing an alternative example implementation of a presentation system 100 according to some embodiments. Figure 8is a perspective view of an exemplary configuration of system 100, shown with a translucent housing 802 to illustrate various internal components of system 100. Figure 7 The implementation shown is similar to Figure 8 802 encloses the CO2 cylinder 110; however, in this example, the CO2 cylinder 110 is shown as being positioned at an angle and extending the length of the housing 802. Although not explicitly shown, at least a portion of the first compressed CO2 passage 112, the first pressure regulator 116, and / or the carbonation system 120 can be enclosed in the fluid system 804. Further, the fluid system 804 can generally include one or more of the second compressed CO2 passage 114, the second pressure regulator 118, and the pump 108. In some embodiments, the pump 108 can be positioned near a connector of the CO2 cylinder 110. For example, the pump 108 can extend from the connector of the CO2 cylinder 110, such as Figure 8 shown.

[0083] It should be understood that although the above reference Figures 1 to 8 Specific configurations of the system 100 are described, but any combination of features described in each of these configurations can be used in further configurations. In other words, any features of the system 100 described above can be used together to form the system 100. As described above, for example, Figures 1 to 3 Any configuration of the system 100 shown in FIG. 1 may include a mixing chamber 138. Likewise, Figure 4 or Figure 5 The configuration of the system 100 shown in FIG. 1 may, for example, include a mixing valve 124. As another example, any configuration of the system 100 described herein may include an in-line implementation of the carbonation system 120 or a carbonation tank implementation of the carbonation system 120.

[0084] Reference now Fig. 9, shows a diagram of system 100 in an example storage environment 900, according to some embodiments. In this example, environment 900 is a residential refrigerator; however, environment 900 may more broadly represent any cooled or refrigerated environment. A residential refrigerator may typically maintain an ambient temperature inside the environment of less than 40°F, and in some cases 35°F to 38°F. Storage system 100 in a cooled environment (e.g., environment 900) allows the temperature of the fluid stored in fluid tank 102 to reach equilibrium with the ambient temperature of environment 900. In other words, the fluid stored in system 100 is refrigerated to or near the temperature of environment 900. As described above, this means that system 100 does not require a separate refrigeration system to cool the fluid. Instead, system 100 may be entirely mechanical and may rely on placement in a cooled environment (e.g., environment 700) to produce a cooled mixed beverage. To this end, system 100 is also typically sized to fit on a shelf of a residential refrigerator, such as Fig. 9 To meet this size constraint, the CO2 cylinder 110 can be positioned horizontally in the system 100, as shown. Figure 7 and Figure 8 As shown, the overall height of the system 100 is reduced.

[0085] Combined mixing bowl and spout

[0086] Reference now Fig.9A and Fig. 9B , a diagram of a combined mixing bowl 900 and outlet 142 for mixing a fluid with one or more additives is shown according to some embodiments. In some embodiments, the combined mixing bowl 900 and outlet 142 (also collectively referred to herein as the mixing bowl 900) is a "mixing area" (e.g., mixing area 140) of the mixing chamber 138, as discussed above. In some embodiments, the mixing bowl 900 is formed of a single piece of metal (e.g., stainless steel) or food-safe plastic. The mixing bowl 900 can be configured to receive a carbonated fluid (e.g., water) and a dispensed additive, and due to the shape and placement of the mixing bowl 900, the carbonated fluid and additive can be mixed in the mixing bowl 900. In some embodiments, the flow of the carbonated fluid causes mixing of the fluid in the mixing bowl 900 with the additive. In addition, the volume of the carbonated fluid in the mixing bowl 900 can help to "wash out" any leftover additives (e.g., flavorings) between the production of mixed beverages.

[0087] Reference now Fig. 10A and Fig. 10B, shows an example diagram illustrating an example implementation of a mixing chamber 138 and / or an outlet of the system 100 according to some embodiments. In this example, the additive cartridge slot 126 is shown as being positioned above or on the top side of the mixing chamber 138. Alternatively, a plurality of buttons (i.e., actuators) may be positioned on top of the mixing chamber 138 that, when actuated by a user, cause the system 100 to mix and dispense a corresponding mixed beverage. For example, Fig. 10B The user is shown pushing a specific actuator or additive cartridge 128. The mixed beverage can then be dispensed from outlet 706.

[0088] Reference now Fig.11 and Fig.12 , respectively, illustrate exemplary implementations of the carbonation system 120 in a series configuration and a batch configuration according to some embodiments. Specifically, Fig.11 Shows the above Figures 1 to 5 And especially in Figure 6 An example of a tandem configuration as described in . Fig.12 As shown above Figures 1 to 5 An example of a batch carbonation configuration as described.
