Portable carbonation dispenser

Abstract

A portable carbonation dispenser utilizes an onboard supply of carbonation gas and a carbonation control module to allow a user to carbonate a base liquid stored in an onboard base liquid container. The carbonation control module may include a user-actuated button for selectively initiating carbonation. The base liquid container may include an extension for increasing the base liquid's exposure to the carbonation gas. A vertical viewing window allows the user to observe the carbonation and base liquid levels in the container. An isolation component is used to isolate the additive cartridge from the carbonation pressure during carbonation in applications where the dispenser uses an additive cartridge. Safety venting and locking features may be provided on a mode selector to prevent accidental pressurization of the cartridge space by the user. A refill station is available for refilling the portable carbonation dispenser.

Description

[0001] Priority claims

[0002] We claim priority to U.S. Provisional Application 63 / 052,348, filed July 15, 2020, entitled “Portable Carbonation System,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure generally relates to beverage forming and dispensing apparatus, systems, and associated methods. Such apparatus, systems, and methods can provide portable (i.e., handheld) beverage dispensers with onboard, user-controlled carbonation features, and can utilize a cartridge to add additives, such as flavorings or supplements, to the base liquid during dispensing. These apparatus, systems, and methods may further relate to refilling stations for refilling the onboard carbonation gas supply to a portable carbonation dispenser. Background Technology

[0004] Recent advances in this field include beverage forming and dispensing systems that utilize replaceable cartridges for mixing additives with a dispensed base liquid (water). These systems can mix flavorings or other additives with the base liquid (water) as the base liquid is dispensed from the container. Examples of such systems are described in U.S. Patent 10,888,826, entitled “Adjustable Additive Cartridge Systems and Methods,” issued January 12, 2021, and U.S. Patent Application US20190291065A1, published September 26, 2019, entitled “Adjustable Additive Delivery Systems and Dispensing Closure Valves for the Same,” both of which are incorporated herein by reference in their entirety.

[0005] Systems and methods for carbonating beverages are known in the art. For example, tabletop soda preparation systems that allow users to carbonate their own beverages are known. However, known systems and techniques are not particularly well-suited for portable beverage dispensers. Furthermore, reusable beverage forming and dispensing systems that can utilize replaceable additive cartridges present additional challenges regarding the application of carbonation systems and techniques in these settings. Improvements are needed in the art to address these and other challenges. Summary of the Invention

[0006] This disclosure provides a portable (i.e., handheld) carbonation dispenser with onboard carbonation features and components that are modular and adaptable for integration while allowing for a compact form factor of the dispenser. For example, in some embodiments, the portable carbonation dispenser may include a compact, portable arrangement of an onboard base liquid container, an onboard carbonation module (which may include one or more carbonation gas containers and a carbonation flow control assembly), all compactly arranged within an ergonomic housing. A base liquid container closure may hermetically engage the base liquid container such that its interior can be pressurized for carbonation. The onboard base liquid container may be shaped with niches or recesses to allow for a compact arrangement of the carbonation gas containers. The carbonation flow control assembly may include flow and pressure control components integrated into a module disposed in the base of the housing for easy assembly and compact arrangement, and may include a user-actuated flow control component including a button accessible from outside the housing for controlling the flow rate of carbonation gas into a base liquid supply source contained in the base liquid container and thus controlling the carbonation level. The carbonation flow control assembly may include a refill connector for receiving refill carbonation gas from a refill station supply source to refill an onboard carbonation gas container. A portable carbonation dispenser allows users to carbonize the base solution to desired levels within the dispenser itself in a portable manner, without requiring a larger (i.e., desktop) carbonation system. The portable carbonation dispenser also allows for the refilling of both base solution and carbonation gas for multiple uses of carbonated water or carbonated beverages.

[0007] This disclosure provides a portable carbonation dispenser with features for isolating the dispensing channel during carbonation to prevent exposure to carbonation pressure. For example, in some embodiments, the portable carbonation dispenser may include a base liquid container closure having a dispensing channel therein and an isolation component integrated into the base liquid container closure for isolating the dispensing channel from the base liquid supply source and the interior of the base liquid container to facilitate pressurization of the base liquid container and carbonation of the base liquid. In one embodiment, the isolation component may include a sealing insert actuated by a mode selection lever on the closure to configure the portable carbonation dispenser to a carbonation mode or a dispensing mode. The insert is rotatable within a journal formed in the container closure and may have one or more insert ports and a blocking surface that cooperates with a corresponding journal port to selectively block or align with the journal port and selectively isolate the dispensing channel from the interior of the base liquid container (carbonation mode) or expose the dispensing channel to the interior of the base liquid container (dispensing mode). Using the operating mode selection lever, users can selectively configure the portable carbonation dispenser to either carbonation or dispensing mode. During carbonation, the dispensing channel can be isolated and protected from exposure to the carbonation gas pressure in the base liquid container.

[0008] This disclosure provides a carbonation feature particularly suitable for dispenser environments using replaceable additive cartridges, which selectively isolates and protects the additive cartridge during carbonation operations. For example, in some embodiments, a portable carbonation dispenser can be used with an additive cartridge mounted in a container or container closure (e.g., in a cartridge receiving space within a container closure dispensing channel). An isolation component of the portable carbonation dispenser can thereby isolate the additive cartridge and protect it from exposure during carbonation mode, and can allow the base liquid to flow into the dispensing channel and through the cartridge in dispensing mode. In one embodiment, the isolation component may include a sealing insert actuated by a mode selection lever on the closure to configure the portable carbonation dispenser to either carbonation mode or dispensing mode. The insert is rotatable within a journal formed in the container closure and may have one or more insert ports and a blocking surface that cooperates with a corresponding journal port to selectively block or align with the journal port and selectively isolate the additive cartridge from the interior of the base liquid container (carbonation mode) or expose the dispensing channel to the interior of the base liquid container (dispensing mode). Using the operating mode selection lever, users can selectively configure the portable carbonation dispenser to either carbonation or dispensing mode. During carbonation, the additive cartridge can be isolated and protected from exposure to the carbonation gas pressure in the base liquid container.

[0009] This disclosure provides features that enhance carbonation within the base liquid container of a portable carbonation dispenser. In some embodiments, the portable carbonation dispenser may include features for enhancing carbonation. In one embodiment, the onboard base liquid container may be provided with an asymmetrical shape, including an extension or well containing a supply column deeper than the rest of the base liquid container. A carbonation gas injector or nozzle may be positioned at the bottom of the extension of the base liquid container, such that the carbonation gas is exposed to the base liquid supply source for an extended period while traveling within the extension, thereby enhancing carbonation.

[0010] This disclosure provides simplified user operation and control of carbonation on a portable carbonation dispenser. In some embodiments, the portable carbonation dispenser may be provided with additional features to prevent the dispensing channel and additive cartridge (if present) from being exposed to carbonation pressure during carbonation operation. For example, the closure may be provided with a vent that can be actuated to release pressure from the base liquid container after carbonation operation and before the portable carbonation dispenser is configured to carbonation mode. The vent may be a push-button valve located on the container closure. Furthermore, the mode selection lever may be provided with a ramp or other surface for actuating the vent push-button valve when the mode selection lever is moved from the carbonation mode position to the dispensing mode position. Thus, venting of the base liquid container can occur automatically when the user operates the mode selection lever, such that any residual carbonation pressure in the base liquid container is released before the user dispenses base liquid from the container for consumption.

[0011] In some implementations, the portable carbonation dispenser may be provided with additional features to prevent the dispensing channels and additive cartridges (if present) from being exposed to carbonation pressure. For example, the closure may be provided with a carbonation level indicator, which may be a spring-biased post or marker that extends upwards through the pressure in the base liquid container when the base liquid supply source is pressurized. The indicator then visually indicates to the user that the base liquid supply source is under pressure. According to another aspect, the mode selection lever may be provided with a stop tab arranged to engage the carbonation level indicator post or marker, thereby preventing the mode selection lever from moving from the carbonation position when the base liquid container is under pressure. This feature, particularly in combination with a vent, provides additional protection against excessive pressure from the base liquid container on the dispensing channels and additive cartridges (if present). According to another aspect, the container closure may be provided with a pressure relief valve to ensure that the pressure in the base liquid container never exceeds a threshold safety level. The pressure relief valve may also allow the user to control carbonation by ensuring that the carbonation pressure remains at a substantially constant value during carbonation.

[0012] According to another embodiment, the portable carbonation dispenser includes user interface features to assist the user in performing carbonation operations. For example, an elongated, axially extending viewing window may be disposed on the base liquid container and arranged to extend through the portable carbonation dispenser housing, making the interior of the base liquid container and the contained base liquid visible to the user. The viewing window may be located above a user-activated carbonation button on the housing. A carbonation gas nozzle may be positioned such that carbonation bubbles are visible through the viewing window during carbonation operations. These features provide the user with a visual indication that carbonation is occurring within the base liquid container. In another embodiment, the container closure is provided with an alignment protrusion for aligning a mode selection lever thereto, indicating to the user that the lever is in the carbonation mode position or the dispensing mode position.

[0013] According to another aspect, the container cap or closure is provided with features for supporting carbonation within the associated container. In one embodiment, the container closure may include: a closure base having a journal including at least one journal port defined therein; a closure insert disposed within the journal of the closure base and having a closure insert wall defining a cartridge receiving space, the closure insert wall having at least one insert port defined thereon and at least one blocking surface, the closure insert being adapted to rotate within the journal to a carbonation position, in which the at least one blocking surface blocks the at least one journal port to isolate the cartridge receiving space; the closure insert being adapted to rotate to a dispensing position, in which the at least one insert is aligned with the at least one journal port to allow flow into the cartridge receiving space.

[0014] According to another embodiment, some embodiments provide a method for preparing carbonated beverages in a portable carbonation system. The portable carbonation system may include an onboard base liquid container, a container closure including a dispensing channel, a gas container for containing a carbonation gas supply source, a carbonation flow control assembly, and an isolation assembly. The carbonation flow control assembly includes a user-actuated flow control component for controlling the flow rate of carbonation gas to the base liquid supply source. The isolation assembly allows the user to selectively isolate the dispensing channel and thereby prevents pressurization of the dispensing channel when the base liquid supply source is pressurized by the carbonation gas. The method may include filling the onboard base liquid container on the portable carbonation system with the base liquid supply source; operating the isolation assembly to isolate the dispensing channel from the base liquid container; and carbonizing the base liquid supply source with gas from the onboard gas container. The method may also include securing a cartridge to the container closure and isolating the cartridge from the base liquid container during the step of carbonating the base liquid supply source. The method may further include operating the isolation assembly after carbonating the base liquid supply source to configure the portable carbonation dispenser into a dispensing mode. The method may further include operating a vent on the container closure to release pressure from the base liquid supply source after carbonating the base liquid supply source. The method may also include operating a mode selection lever on the container closure to operate an isolation component. The method may further include operating the vent by moving the mode selection lever.

[0015] This disclosure provides a reusable portable carbonation dispenser that can be refilled with carbonated gas from a refill station. According to another aspect, the portable carbonation dispenser can be used in conjunction with a refill station. The refill station may include a housing for supporting components of the refill station, a refill gas container disposed within the housing, a portable carbonation dispenser interface, and a refill gas flow control assembly. The portable carbonation dispenser interface is used to connect the portable carbonation dispenser to the refill station and to allow gas flow from the refill gas container to the portable carbonation dispenser. The refill gas flow control assembly includes a flow control valve for controlling the gas flow from the refill station gas container to the portable carbonation dispenser; the refill gas flow control assembly also includes a user actuation lever for selectively operating the flow control valve. In some embodiments, the refill station can be used to refill the portable carbonation dispenser (refilled with carbonated gas). The refill station may include a dispenser base for supporting the portable carbonation dispenser. The dispenser base may have an alignment recess for receiving and centering the bottom of the container, such that a quick-connect fitting aligns and engages with a refill station connection fitting on the dispenser's carbonation control module. A lock-and-release button on the distributor base allows for the quick-connect fitting to lock and release with the refill station connection fitting. The refill gas container 510 can be arranged and adapted to contain carbonated gas in liquefied or gaseous form, such as carbon dioxide. Carbonated gas is supplied from the refill gas container to the refill valve. Once the portable carbonated gas distributor is locked in place, the user can actuate the refill valve using an actuator rod. During refilling operation, carbonated gas is thus supplied from the refill gas container through the onboard gas container refill manifold in the onboard carbonated gas flow control assembly to the portable carbonated gas distributor and then to the onboard gas container. During refilling, the pressure in the onboard gas container can be controlled using a pressure reducing valve on the container closure, which provides the user with an audible indication that the onboard container has been fully refilled.

[0016] According to another aspect, some embodiments provide a method for refilling a portable carbonation dispenser using a refill station. The refill station may include a housing for supporting components of the refill station, a refill gas container disposed within the housing, a portable carbonation dispenser interface, and a refill gas flow control assembly. The portable carbonation dispenser interface is used to connect a portable carbonation dispenser to the refill station and to allow gas to flow from the refill gas container to the portable carbonation dispenser. The refill gas flow control assembly includes a flow control valve for controlling the flow of gas from the refill station gas container to the portable carbonation dispenser, and further includes a user actuation lever for selectively operating the flow control valve. The method may include attaching a portable carbonation system to the refill station; filling an onboard gas container on the portable carbonation system from the refill gas container; removing the portable carbonation system from the refill station; carbonizing a base liquid supply source with gas from the onboard gas container; reattaching the portable carbonation system to the refill station; and refilling the onboard gas container from the refill gas container.

[0036] An exemplary portable carbonation dispenser according to aspects of this disclosure in Figures 1 to 11 As shown in the image. See also for more details. Figures 1 to 3 The portable carbonation dispenser 50 may include the following main components: a housing 10, a base liquid container 100, a carbonation module 200, and a closure 300 for receiving an additive cartridge 400. The base liquid container 100 and the carbonation module 200 may be compactly mounted within the housing 10. The housing 10 may include an outer wall 12 and a separate housing base 13 having a generally cylindrical or hourglass ergonomic shape suitable for user gripping, the housing base being detachably attached to the bottom of the housing 10. The outer wall 12 and the housing base 13 may define an internal space 14 for accommodating other system components. The housing 10 may include an elongated, axially extending viewing window cutout 18 that receives a complementary-shaped, transparent base liquid container viewing window 118 formed on the base liquid container 100 to allow the user to observe its interior. The housing 10 may also include a button cutout 20 for receiving a carbonation control button 262 on the carbonation module 200. The carbonation control button 262 is recessed within the housing 10 to prevent accidental actuation. The recessed top 16 of the housing 10 receives and aligns with a complementary-shaped, circumferentially extending overhang 116. These complementary mating elements provide a secure fit, aid in positioning during assembly, and add visual interest to the entire portable carbonation dispenser 50. The internally threaded tip 120 of the base liquid container 100 receives and secures the externally threaded base 310 of the closure 300, which may include an O-ring seal adapted to maintain pressure within the base liquid container 100.

[0037] The internal space 14 of the housing can accommodate a base liquid container 100 for containing a supply source of base liquid such as water or other beverage precursor liquids. The base liquid container 100 may include an internal chamber 102 with an asymmetrical shape, which advantageously improves the carbonation of the base liquid. More specifically, the internal chamber 102 may include an extension or well recess 104 with increased depth. A carbonation gas nozzle receiver 110 may be located below the base liquid container extension 104 and may receive a carbonation nozzle 256 of the carbonation flow control assembly 220. Small channels in the carbonation gas nozzle container allow a flow of carbonation gas to be introduced into the base liquid at the bottom of the extension 104. Thus, as the carbonation gas travels upward through the extended depth of the base liquid, the extension provides extended exposure of the base liquid to the carbonation gas, thereby increasing the achieved level of carbonation, for example, compared to a base liquid container without this feature. Additionally, as... Figure 4 As best shown in the cross-section, the asymmetrical shape of the base liquid container 100, including the extension 104 and the intermediate base plate 108, can define a niche or recess 106, which can accommodate the airborne carbonized gas container 210 and provide a compact arrangement of the carbonized gas container 210 and the base liquid container 100 within the housing 10.

[0038] For more specific reference Figures 5 to 7 The carbonation module 200 may include an onboard carbonation gas container 210 and a carbonation gas flow control assembly 220. The carbonation module may include components for controlling the flow rate and pressure of the carbonation gas delivered to the base liquid contained in the base liquid container 100, and the carbonation module may provide refilling of the carbonation gas container 210 from an external refill station, as will be described. The carbonation module 200 may be a compact module adapted and arranged to be assembled within a housing 10 having one or more components, disposed in the lower portion of the housing 10 and secured to a base plate 222, which may be mounted to the container base 13. This arrangement facilitates the assembly of the portable carbonation dispenser because the carbonation module can be pre-assembled before being inserted into the housing 10 as a unit.

[0039] The carbonation gas flow control assembly 220 may include a refill connection fitting 230 disposed in a circular recess 224 in the base plate 222 to allow the refill connection fitting to be aligned with mating parts on the refill station. Figure 7The interconnections between components of an exemplary fluid (gas) line and carbonation module 200 are illustrated. Physically, these components can be connected to suitable piping for conveying carbonized gas between the components. A refill connection fitting 230 can receive refilled carbonized gas, which then flows through a check valve 232 to prevent backflow. The carbonized gas then flows through a container 4-port manifold 240, which may include an onboard gas container fitting 248 for engagement with an onboard gas container 210 (see also...). Figure 4 The container manifold 240 thus allows refilling into and out of the onboard gas container 210. The container manifold 240 may also include an integrated burst diaphragm 246, which acts as a safety pressure relief valve against excessive pressure in the onboard gas container 210 and other components in the circuit. The container manifold 240 also delivers gas from the onboard gas container 210 to a pressure regulator 250, which regulates (i.e., maintains a constant pressure) the pressure in the circuit downstream of the regulator 250 and in the carbonated gas supplied to the distributor carbonation valve 260, which can be actuated by a user button to allow carbonated gas to flow through the nozzle check valve 254 and to the carbonation nozzle 256, thereby providing a flow of carbonated gas into the base liquid container 100 and the base liquid contained therein. Therefore, the carbonation module 200 allows the user to supply the desired level of carbonation to the base liquid by activating the user-actuated button 262.

[0040] Figure 7 Additional components that may be included in the base liquid container closure or cap 300 are shown. The closure 300 provides a proper seal to the base liquid supply source to allow the interior of the base liquid container 100 to be pressurized to a level sufficient to dissolve carbonated gas in the base liquid. The closure 300 may also include components for controlling and indicating (sensing) the carbonation pressure within the base liquid container 100. These components may include a vent 380 (to the environment), a carbonation level indicator 386, and a pressure reducing valve 390. The function of these components will be explained in more detail later in this disclosure.

[0041] The carbonation system according to this disclosure is particularly suitable for dispensers using replaceable additive cartridges. For example, a closure 300 may be used to mount a replaceable flow-through additive cartridge 400. This cartridge 400 may include features similar to those described in U.S. Patent No. 10,888,826 above. The cartridge 400 may be mounted in the dispensing channel of a container cap or closure and may have a configuration and features that mix the additive with the base liquid as it flows through the cartridge. This cartridge may also allow the user to adjust the amount of additive added to the base liquid flow via rotation of a flavoring disc on the cartridge. Referring to this disclosure… Figures 2 to 4The barrel 400 may have a dispensing nozzle 402, an opposing inlet end 404 having one or more channels to allow the base liquid to flow in, and a threaded base 406 for securing the barrel 400 to the threaded dispensing channel 302 in the closure 300.

[0042] According to aspects of this disclosure, features are provided to support carbonation in a dispenser environment including the aforementioned additive cartridge. More specifically, features are provided for isolating the additive cartridge from the base liquid supply source and for accompanying higher pressure within the base liquid container during carbonation. It should be understood that the isolation component described herein also isolates the dispensing channel 302 of the closure 300, and can be used even when the additive cartridge is not in use or is not present in the dispensing channel 302 (i.e., where the user carbonizes in a portable carbonation container and dispenses only water). Figure 8.1 and Figure 8.2 An isolation component arrangement is schematically shown, wherein features may be disposed on a container closure 300 to provide selective isolation of the additive cartridge (or dispensing channel, which may be assumed to be represented by the same frame 400) during carbonation operation in a portable carbonation dispenser. The isolation component 320 provides a selectively permeable barrier in dispensing modes ( Figure 8.1 In this configuration, the barrier is arranged and adapted to expose the barrel to the base liquid flow and allow for dispensing operations of the container closure 300, wherein the base liquid flow (long dashed line) 120 generates an additive flow 420 (short dashed line) and a mixed flow 330 (short / long dashed lines) from the barrel nozzle. In this configuration, the barrier is permeable, indicated by the dashed lines defining the isolation member 320. The isolation member 320 can be configured in a carbonation mode ( Figure 8.2 In this configuration, a permeable barrier is arranged and adapted to isolate the barrel 400 from the base liquid supply source and container, so that the barrel 400 is not exposed to the carbonation pressure generated therein by the carbonation module 200. In this configuration, the isolation barrier is impermeable and is capable of isolating the dispensing channel from the pressure in the base liquid container 100, indicated by the solid line defining the isolation member 320.

[0043] According to other aspects of this disclosure, exemplary implementations of the isolation component may be set as follows: Figures 9 to 11 The container closure 300 shown. The main components of the closure 300 may include a closure base 310, a closure cover 330, a closure insert 350, an insert seal 360, and an actuating rod 340. Figure 9 and Figure 12 The enclosed shield 330 is shown, while Figure 10 and Figure 11For clarity, the closure shield is omitted. The closure shield 330 may include an integral handle 332. The closure base 310 may include an annular journal 312 for receiving the closure insert 350 and one or more journal ports 314 arranged to allow the base fluid to flow from inside the base fluid container into the interior of the journal 312. Figure 11 Two journal ports 314 are shown (the third is hidden from view). The closure base 310 may include a vent 3, which may be a spring-biased button 381 adapted to release pressure in the base fluid container when pressed by a user or by an inclined surface 346 on an actuating rod 340 relative to the closure base 310, as will be further described later in this disclosure. A pressure-reducing valve 390 may also be included on the closure base 310 and may be characterized as a lift valve or other type of valve that releases pressure when a threshold pressure is reached, and thus is capable of controlling and maintaining a limited pressure within the base fluid supply source container. The closure base 310 may include an overmolded gripping ring 318 to allow a user to grip and remove or install the closure 300 relative to the base fluid container 100.

[0044] The closure insert 350 may include a cylindrical outer wall 351 extending to the end wall 353 to define an inlet end 404 for receiving the feed cylinder 400 (see [link]). Figure 2 and Figure 3 The internal barrel receiving space 352 of the insert 350. As will be appreciated, the barrel receiving space 352 also provides a portion of a dispensing channel. The threaded end 356 of the insert 350 can engage the threaded cap 406 of the barrel 400 to secure the barrel 400 to the insert. A plurality of snap-fit ​​recesses 358 may be provided on the cylindrical rod receiving surface 357 to secure the mode selection lever 340 to the closed insert 350 after assembly into the closure base 310. The closed insert 350 may include a plurality of (in this case, three) insert ports 354, which allow the base fluid to flow from the outside into the internal barrel receiving space 352. A plurality of blocking surfaces 35 are distributed between the insert ports 354. The insert 350 may include a seal retaining channel 370 having two circumferentially extending upper sections 372 and lower sections 374 and a plurality of axially extending sections 376 extending between the upper sections 372 and lower sections 374. The seal retaining channel 370 can receive a resilient (i.e., modified O-ring) insertion seal 360 having a shape complementary to the two rings 362 and 364 and a plurality of axially extending transverse members 366.

[0045] As will be appreciated from this disclosure, when the closure insert 350 is installed and positioned within the closure base journal 312, the insert port 354 and the blocking surface 355 are arranged to cooperate with the journal port 314 on the closure base 310. Rotation of the insert 350 to the dispensing position aligns the insert port 354 with the journal port 314, allowing the base liquid to flow into the inner barrel receiving space 352. Rotation of the insert 350 to the carbonation position aligns the blocking surface 355 with the journal port 314, isolating the inner barrel receiving space 352 and thus the mounted barrel 400 from the base liquid container, allowing carbonation pressure to be applied therein without affecting the barrel 400. In this example, the aforementioned features on the insert 350 and the closure base 310 cooperate to provide an isolation component that allows the user to selectively isolate the barrel from the pressure in the base liquid container 100. As will be appreciated, when rotation occurs, the insert seal 360 provides a seal inserted into the base journal 312 of the closure. The insert seal 360 also provides a corresponding sealing engagement of each blocking surface 355 with the inner wall of the base journal 312 of the closure, and provides a seal completely surrounding each journal vent 314 when the insert 350 is in the carbonation position, thus providing a seal against the relatively high pressure of the base liquid container 100 during carbonation operation.

[0046] The mode selection lever 340 provides the user with actuation (rotation) of the closure insert 350 to configure the closure 300 into a dispensing mode or a carbonated mode. The mode selection lever 340 may include an actuation handle 342 and an annular ring 344 adapted to surround the rod engagement surface 357 of the insert when it is mounted thereon. The mounting position of the mode selection lever 340 on the insert 350 is... Figure 10 As best shown in the diagram. A plurality of snap-fit ​​protrusions 348 may be provided on the inner surface of the annular ring 344 to engage a similar number of snap-fit ​​recesses 358 on the engagement surface 357, thereby providing easy assembly and fastening of these components.

[0047] like Figure 9 As best seen, when the mode selector lever 340 and the closure cover 330 are mounted on the closure base 310, the mode selector lever handle 342 extends through a guide groove 336 in the closure cover 330, which guides and provides limited movement (rotation) of the mode selector lever 340. An alignment protrusion 316 extends from the closure base 310, and its profile mates with a similar surface of the mode selector lever handle 342. The alignment protrusion provides visual and tactile indication that the mode selector lever handle 342 is in a carbonated mode, which is... Figure 9 and Figure 10 The location shown.

[0048] According to aspects of this disclosure, the closure 300 may be provided with additional features to control carbonation pressure and ensure that the cartridge 400 is not exposed to carbonation pressure during operation. The closure 300 may be provided with an interlocking feature that prevents the user from switching to drinking mode if the base liquid supply source is pressurized. In an exemplary embodiment, the mode selection lever 340 may be provided with a stop tab 347. Figures 9 to 11 The closure base 310 is equipped with a retractable carbonation level indicator mark or post 387, which is positioned to protrude upward from the closure base 310 when a suitable carbonation pressure is achieved in the base liquid container 100. The carbonation level indicator post 387... Figure 10 The column 387 is shown in the retracted position within the container base 310. When the base liquid container is pressurized with carbonated gas, the column 387 extends upward and prevents the stop tab 347 from moving, and thus prevents the user from switching the portable carbonation dispenser to dispensing mode. As will be appreciated, the carbonation level indicator column 387 can be positioned so that the user can observe it through a transparent viewing lens 334 within the enclosed cover 330. Figure 9 )observe.

[0049] According to another aspect, the closure 300 may be provided with a vent 381 for releasing pressure from the base fluid container 100. The vent 381 may be a push-button type valve having an exposed actuating surface extending from the closure base 310 and housed within a base on the closure base. The venting surface may be arranged and adapted to engage with an inclined surface 346 on the mode selection lever 340, which, when the mode selection lever 340 is rotated ( Figure 9 and Figure 10 (Counterclockwise direction in the middle), the inclined surface engages with the surface and presses down the button. Therefore, when the user switches the dispenser to dispensing mode and before the internal cartridge receiving space 352 of the insert 350 is exposed to the base liquid supply source, the vent 381 ensures that pressure is released from the base liquid container 100 to the ambient / atmosphere. The vent 381 can also be directly operated by the user (i.e., by engaging the surface of the vent 381 with the user's finger, thumb, pen tip, or other element) to release any pressure accumulated within the base liquid container 100.

[0050] According to another aspect of this disclosure, the closure 300 may be provided with a pressure reducing valve 390, which may be configured at a threshold pressure to limit the maximum pressure within the base fluid supply source container. The pressure reducing valve 390 may be a known configuration having a spring-biased sealing element configured to disengage from the valve seat and release pressure above a predetermined limit (typically 60 psi).

[0051] Figure 13The steps of an exemplary method for operating a portable carbonation dispenser such as those described above are illustrated. In step 1310, the user fills the base liquid container 100 and then secures the container closure 300. In step 1320, the isolation component is switched to carbonation mode. In step 1330, the user presses the carbonation button 262 (… Figure 1 The base liquid supply source is carbonized, thereby releasing carbonated gas from the onboard gas container 210 into the base liquid supply source. In step 1340, the isolation component is then switched to dispensing mode. This step may include an intermediate step of initially releasing pressure from the base liquid container. In step 1350, the carbonated beverage is then dispensed from the dispenser, and as the base liquid flows through the closure 300, the carbonated beverage can be flavored with additives from the cartridge.

[0052] According to another aspect of this disclosure, the portable carbonation dispenser can be refilled (with carbonated gas) using a refill station. Figure 14 and Figure 15 An exemplary refill station 500 arrangement is shown in the figure. Figure 16 This is a schematic diagram of exemplary components of a refill station and their functional relationships. The refill station 500 may include a main housing 505 for accommodating system components and having a dispenser base 507 for supporting a portable carbonation dispenser 50. The dispenser base 507 may have an alignment recess 509 for receiving and centering the bottom of a container 13 (see [reference]). Figure 1 This allows the quick-connect fitting 528 to align and engage with the refill station connection fitting 230 on the dispenser carbonation flow control assembly 220 (see...). Figure 6 The lock release button 510 on the dispenser base 507 allows for quick locking and releasing of the connection accessory 528 to the refill station connection accessory 230.

[0053] A refill gas container 510 may be arranged and adapted to contain carbonated gas, such as carbon dioxide, in either liquefied or gaseous form. Typically, when the carbonated gas is stored in liquid form, the upper part of the internal space of the gas container 510 will contain a supply source of the gaseous form present in equilibrium with the liquid form residing in the lower part of the internal space. The refill gas container 510 may have an outlet fitting fixed to its upper part to allow the gaseous supply source to be in carbonated form, regardless of the form stored in the container. Carbonated gas is supplied from the refill gas container 510 to the refill valve 526. Once the portable carbonate dispenser 50 is locked in place, the user can actuate the refill valve 526 using the actuator lever 524. During refilling operation, the carbonated gas is thus drawn from the refill gas container 510 through the control valve 526 and through the onboard gas container refill manifold in the onboard carbonated gas flow control assembly 220. Figure 5 and Figure 7 ) supplied to airborne gas container 210 ( Figure 4 During refilling, the pressure in the airborne gas container 210 can be controlled using a pressure reducing valve 390, which provides the user with an audible indication that the airborne container 210 has been fully refilled.

[0054] Figure 17 An exemplary method for filling a portable carbonation dispenser with carbonation gas using a refill station according to aspects of this disclosure is shown. In step 1710, the airborne base liquid container 100 ( Figure 4 The base liquid can be filled. This can be an optional step, as refilling of the onboard carbonation system can occur regardless of the state of the base liquid container (full or empty). In step 1720, the portable carbonation dispenser is secured to the refill station 500, including, for example, a locking connection to the quick-connect fitting 528. In step 1730, the user can actuate the refill valve actuation lever 524 to open the refill valve 526 and allow gas to flow from the refill gas container 510 to the onboard gas container 210. In step 1740, after the airflow is interrupted, the user can remove the portable carbonation dispenser 50 from the refill station by, for example, pressing the locking release button 510. In step 1750, the user configures the dispenser to the carbonation mode as described above, and the user actuates the carbonation button 262 ( Figure 1 To achieve the desired level of carbonation, the base liquid can be carbonated on a portable carbonation dispenser.
