PORTABLE BREWING SYSTEM WITH REAL-TIME DILUTION CONTROL ANDCONSISTENT FLOW-RATE TECHNOLOGYRELATED APPLICATIONS

[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 626,260, filed on January 29, 2024, U.S. Provisional Application No. 63 / 548,987, filed on February 2, 2024 and U.S. Provisional Application No. 63 / 548,990, filed on February 2, 2024. The entire teachings of the above applications are incorporated herein by reference.BACKGROUND

[0002] Traditional brewing methods are inherently stationary, relying on a fixed location with access to brewing equipment and a heat source. Effective within the confines of a home or commercial environment, these methods are ill-suited to the dynamic nature of modern lifestyles, which often include activities such as travel or outdoor adventures where such equipment is unfeasible. Moreover, the temporal aspect of traditional brewing is a drawback; once the brewing process is complete, the beverage begins to deteriorate in taste and quality, necessitating immediate consumption to enjoy the full breadth of its intended flavor.

[0003] Portable brewing solutions to date, such as instant mixes or pre-packaged beverages, trade the richness and depth of freshly brewed drinks for convenience, leading to an inevitable degradation of flavor quality. These methods lack the capability of real-time dilution control, which results in a suboptimal beverage that is often either too potent or too weak to meet the consumer's expectations.SUMMARY

[0004] The present disclosure can provide a portable dual-channel brewing system or beverage container that caters not only to coffee or tea but to a broad spectrum of beverages and concentrates. By enabling real-time interaction between the water and the brewing medium, it can provide optimal freshness at the moment of consumption. This system can address the issue of inconsistent beverage concentration, particularly prevalent in initial sips, which can be too intense for the consumer's palate, detracting from the overall enjoyment of the drink.

[0005] The present disclosure can provide a beverage container including a liquid reservoir for containing a liquid, and an additive compartment below the liquid reservoir for holding an additive.

[0029] A description of example embodiments now follows.

[0030] The present disclosure can provide a brewing system or beverage container that can allow for precise real-time dilution, delivering a consistent and enjoyable taste from the first sip through to the last, a feature not just desirable but essential for consumer satisfaction across a variety of beverages. A valve mechanism can be located at the intersection of two fluid channels to allow the user to adjust the proportion of diluting liquid or water to the brewed or mixed liquid. This adjustment can maintain the desired flow-rate of consumption while fine-tuning the strength of the beverage.

[0031] The portability of this system facilitates a high-quality brewing or mixing experience in diverse environments, from an office desk to the remote outdoors. The result is a comprehensive brewing system that delivers convenience, control, and adaptability in the consumption of a broad spectrum of beverages.

[0032] Referring to FIGs. 1 and 2, an embodiment of a portable brewing system, beverage bottle or container 10 can include a compact unit, bottle, vessel, shell or container 12 having an inbuilt liquid or water compartment 14, and a separate beverage material or additive compartment 16 for beverage brewing or mixing materials, additives, ingredients, consumables or concentrates 16a, facilitating the preparation of beverages.

[0033] A liquid or water chamber or reservoir 18 can provide the main storage for a liquid or water 18a, required in the brewing process and is capable of holding enough liquid 18a to allow for the preparation of multiple beverages.

[0034] A liquid entry flow channel 20 can direct a brewing liquid stream which is not necessarily confined to a single channel. This stream of liquid 18a can be directed from the water reservoir 18 into the beverage material or additive compartment 16, to begin the brewing process, in which certain elements of the brewing or beverage materials 16a are steeped, extracted, combined, absorbed or leached into the liquid or water 18a, thereby mixing with the liquid or water 18a to form a brewed beverage or mixed liquid 35.

[0035] The component through which the user consumes the beverage can be a drinking straw 22 and is connected in fluid communication with the beverage material compartment 16. As shown in FIG. 1, the straw 22 can extend through the outside top cover 24, through the liquidor water compartment 14, and into an adjustable dilution twist valve mechanism 26. The adjustable valve 26 can be manipulated by the user by twisting the straw 22 in either direction to regulate the dilution of the beverage by controlling the stream of diluting liquid 18a.

[0036] A channel or fluid flow opening, orifice, passage or aperture 32 can form the dilution liquid stream which can be a stream through which additional diluting liquid 18a can be introduced into the straw 22. The channel 32 can form a part of the system 10 that allows the user to adjust the beverage's strength in real-time. In some embodiments two channels 32 can be used.

[0037] The adjustable valve 26 can be attached to the straw 22. This valve 26 can be manipulated by the user by twisting the straw 22 in either direction, which in turn twists the connected valve 26 in either direction, to regulate the dilution of the beverage by controlling the stream of liquid 18a from the water reservoir 18 through the valve 26.

[0038] A brewed material or mixed liquid exit flow channel 28 can form a pathway through which the brewed material, beverage or liquid 35 exits the brewing compartment 16 and enters the straw 22 for consumption.

[0039] The beverage material compartment 16 can accommodate the beverage material 16a in various forms, such as loose for refillable use or pre-packaged for disposable use.

[0040] A continued channel 30 is shown entering into the brewing compartment 16. The continued channel 30 refers to any stream of liquid 18a that enters the beverage material compartment 16 for the brewing process, emphasizing the flexibility of the system in terms of the number and arrangement of streams.

[0041] Each component of the portable system 10 can work in harmony, allowing the user to brew and consume a beverage with the desired strength and consistency. The portable system 10 can ensure each serving is freshly prepared and personalized according to the user's taste.

[0042] FIG. 3 illustrates channel 20 directing a stream of liquid or brewing liquid 18a. Channel 20 can represent the path through which liquid 18a, generally water, travels from the liquid reservoir 18, engaging with the brewing material 16a in the brewing compartment 16 to start the brewing process. The term 'channel' here indicates the functionality of the stream and not the physical count of channels.

[0043] Channel 32 forming the dilution liquid stream represents an additional stream that can merge with the brewed beverage 35, allowing for real-time dilution to the user’s desired concentration. The use of the word 'channel' encompasses any such stream that contributes to the dilution process.

[0044] The brewing material compartment 16, as shown in FIGs. 1 and 2, can accommodate various forms of brewing materials 16a or concentrates, either in a refillable or disposable packaging, providing flexibility in the brewing process.

[0045] The user-adjustable dilution valve 26 can be located within the flow path 32. This valve 26 can allow the user to adjust the balance between the brewed liquid 35 stream and the dilution liquid 18a stream, therefore controlling the strength of the final beverage 36.

[0046] The final output 36 is the beverage prepared to the user's preferred concentration, consistently maintained without affecting the liquid's flow rate.

[0047] The flow diagram of FIG. 3 shows the brewing and dilution process, including the unique dual-channel mechanism and real-time dilution control.

[0048] Channel 20 entering into the brewing compartment 16 refers to any stream of liquid 18a that enters the beverage material compartment 16 for the brewing process, emphasizing the flexibility of the system in terms of the first compartment serving as a reservoir 18 for water 18a, which can be a solvent in the brewing process. This compartment 18 can hold a sufficient volume of liquid or water 18a, ensuring multiple servings can be prepared without the need for frequent refills, thus enhancing the system’s portability and convenience.

[0049] Positioned adjacent to or below the liquid or water reservoir 18, the second compartment 16 can house the brewing material 16a. This compartment 16 can accommodate a variety of beverage materials, including but not limited to pods 42, such as K-cups, and can hold the brewing material 16a securely while allowing for the free flow of water 18a through the material 16a, facilitating an efficient extraction of flavors and aromas.

[0050] The dual-channel mechanism can provide two pathways for liquid or water 18a during the brewing cycle. The first channel 20 can direct liquid or water 18a from the reservoir 18 into the beverage material compartment 16. Here, the water 18a interacts with the brewing material 16a, leaching out the desired flavors to create a concentrated brew or mixed liquid 35. This compartment 16 can ensure that the brewing material 16a is fully saturated, maximizing the extraction process.

[0051] Once the brewing phase is initiated, the brewed or mixed liquid 35 transitions into the second brewed or mixed liquid exit flow channel 28. This channel 28 transports the brewed liquid 35 from the compartment 16 to the user's mouthpiece, via the straw 22. The positioning of the channels 20 and 28 can ensure that the brewed liquid's 35 journey is streamlined and can prevent backflow, maintaining the beverage quality.

[0052] The straw 22 can be attached to the dilution valve 26. The user can manipulate this valve 26, which is accessible and straightforward to operate by twisting of the straw 22, to adjustits opening. This action can vary the admixture of water 18a with the concentrated brew 35, allowing the user to customize the beverage's strength according to preference. The valve 26 design can provide precision in controlling the dilution, providing the user with the ability to fine-tune the beverage's intensity with each sip.

[0053] Furthermore, compartment 16 can adapt to various forms of brewing material 16a, whether it is loose, for those who prefer a refillable option, or pre-packaged in a pod 42, for users seeking the convenience of disposable forms. This adaptability offers a choice between reusability and convenience.

[0054] The present disclosure can provide embodiments of a portable beverage container with at least the following features.1. A portable brewing system comprising: a. an integrated water reservoir for storing liquid prior to brewing or mixing; b. a beverage material compartment for housing brewing material or concentrates; c. a flow mechanism through which liquid is directed from the reservoir into the beverage material compartment to commence or prime the brewing or mixing process, where the process of priming can ensures beverage material flows into a flow path allowing transition from the beverage material compartment to the user interface, where priming can also act as a pressure release mechanism in a pod chamber, letting liquid into the chamber and then out of the chamber; d. a user interface comprising a straw for consumption of the beverage; e. a flow control system allowing for the introduction of liquid into the brewed beverage stream for real-time adjustment of beverage strength; f. an adjustable valve mechanism connected to the user interface, operable to alter the flow of liquid for real-time beverage strength customization without being restricted to a specific number of channels; g. a flow path for the brewed beverage allowing its transition from the beverage material compartment to the user interface, which can be combined with additional liquid for dilution as necessary; h. the beverage material compartment being configured to accept brewing material in a variety of forms, including but not limited to refillable and disposable options; and i. a flow regulation means to ensure a consistent delivery of liquid for the brewing process, accommodating various streams entering the system.2. The flow control system can manage the proportion of liquid streams entering both the beverage material compartment and any additional compartment between the brewingprocess and user consumption, providing flexibility in the brewing system's design and function.3. The flow mechanism and flow control system can work in unison to deliver a user- specified concentration of beverage, ensuring consistency in flavor and strength with each use.4. The system can include a means to control the total stream of liquid entering the system for brewing and dilution, irrespective of the number or configuration of channels or compartments involved.

[0055] The portable beverage brewing system can include a dual-channel mechanism that allows for real-time interaction between water and a beverage material compartment, enabling on-the-spot brewing directly into a user’s cup. This system can feature an adjustable valve integrated within a straw, providing the user with the capability to control the dilution of the beverage as they drink, thus customizing the beverage strength to their individual taste preference in real time. The dual-channel design can ensure a consistent flow-rate of consumption, whether the beverage is enjoyed strong and undiluted or milder and diluted.

[0056] The present disclosure can also provide embodiments of an integrated beverage brew or mixing bottle system or portable beverage container having a bottom-loading mechanism (FIGs. 2 and 4-8) designed to insert and secure disposable pods 42, which may contain preportioned coffee, tea, hot chocolate, or other consumables such as flavors, mixers, vitamin supplements, and fruit concentrates. The ability to brew or mix beverages in situ, directly in the bottle, using water introduced to the pods 42, can eliminate the need for traditional brewing appliances. This feature, coupled with the system's ease of use, efficiency, and portability, makes it especially suitable for individual use across diverse environments, including homes, offices, outdoors, or during travel.

[0057] Positioning the pod 42 below the liquid or water reservoir 18 allows gravity to facilitate the natural flow of liquid or water 18a into the pod 42, to ensure the ingredients 16a are properly primed for brewing or mixing. This priming can provide a full-flavored extraction when the user initiates suction, as it ensures that the ingredients 16a are consistently ready for the brewing process upon demand. The bottom-loading configuration enables a gravity-assisted brewing cycle that primes the ingredients 16a effectively and ensures stability and ease of handling for on-the-go use.

[0058] The bottom-load system simplifies the insertion of pods 42, eliminating the awkwardness and potential mess of top-loading. It also ensures that the weight of the pod 42 on the bottom contributes to the stability of the bottle 12 when set down.

[0059] By positioning the disposable pod 42 at the bottom, it remains primed for brewing, with the contents kept moist and ready for extraction. This orientation protects the pod 42 from the common issue of ingredient desiccation during the idle state which is nothing but in between the process of sipping through the container.

[0060] Moreover, with the disposable pods 42 situated at the bottom, each brew ensures that the liquid 18a interacts fully with the pod contents, facilitating a thorough and efficient extraction process. This placement also allows the use of a supplemental accessory, such as a hot plate, heating pad or coaster 78 (FIG. 4), tailored to work with this system. The hot plate 78 can align with the bottle's 12 base, using minimal energy to maintain the brewed beverage at an optimal temperature. Such an accessory can offer additional convenience, allowing for the beverage to be kept warm for extended periods.

[0061] Placing the pod 42 at the bottom ensures that the ingredients are ready for brewing, resulting in a rich and flavorful beverage from the first sip. This consistent priming provides steady and efficient flavor infusion.

[0062] The bottom-loading mechanism can optimize the placement of the pod within the brewing environment, ensuring effective extraction and a consistently high-quality beverage experience. This strategic positioning also allows for a longer travel path for the brewed or mixed beverage 35, enabling the integration of a post-brew dilution mechanism such as the adjustable dilution valve 26. Accessories such as a hot plate, heating pad or a heating coaster 78 can be used in close proximity to the pod 42. This proximity is an advantage of the bottomloading design, as it allows for direct and efficient heat transfer. The use of such heating accessories can maintain the contents of the pod 42 at a controlled temperature, which can achieve optimal brewing conditions. Maintaining a consistent temperature during brewing is known to impact the extraction quality, flavor, and overall richness of the beverage.

[0063] The combination of the bottom-loaded pod system with heating accessories can create a synergistic effect, enhancing both the functionality and the user experience of the beverage brew bottle system.

[0064] In one embodiment, both the entry and exit channels for the water into and out of the coffee pod 42 can be on the same side of the pod 42. This can consolidate the flow paths, thus offering a compact and efficient system. Other embodiments can have entry and exit channels are located on opposite sides of the pod 42 (FIG. 9). Here, hot water enters from the bottom of the pod 42, and the brewed beverage is extracted from the top, enabling a more traditional flow- through brewing process while still retaining the benefits of the bottom-loading design. This can cater to a broader range of user preferences and brewing styles.

[0065] The system 10 can include a bottom receptacle 70 below the liquid or water chamber or reservoir 18 for receiving and securing a disposable pod 42. The pod 42 can contain a single serving of beverage ingredients 16a such as coffee or tea.

[0066] The engagement mechanism 72 within the receptacle 70 can provide a secure locking and sealing function when the pod 42 is inserted. The engagement mechanism 72 can be actuated manually through an external control 76, such as buttons or tabs. The system 10 can accommodate pods 42 capable of being pierced on both a single side 42a and on two opposite sides top 42a and bottom 42b, catering to different brewing methods and user preferences.

[0067] Once engaged by the engagement mechanism 72, the disposable pod 42 can be pierced by a mechanism such as a liquid entry flow needle 38 and a mixed liquid exit flow needle 40, to facilitate the ingress and egress of liquid. This process benefits from gravity, which assists the flow of liquid or water 18a, ensuring a thorough saturation of the ingredients 16a, a process known as priming. Priming maintains the moisture of the ingredients 16a, preventing them from drying out between uses and guaranteeing a consistent quality of brew. This presents a advantage over top-loading systems, where the pod's position above the liquid reservoir often leads to ingredient desiccation due to dripping and subsequent drying.

[0068] After brewing, the brewed or mixed beverage 35 is extracted from the pod 42 by the user's application of suction through a fluid communication channel, or straw 22 that connects or extends from the bottom receptacle 70 to the container's top 24. The design can harness both gravity and the negative pressure generated by the user to optimize the brewing cycle, blending simplicity with functionality.

[0069] Positioning the pod 20, a distance away from the point of consumption, provides the ability to modulate the strength of the brewed beverage. This is facilitated by the extended path the beverage travels from the brewing location to the point of consumption to provide space for the adjustable dilution valve 26 positioned within the path, such as within or at the bottom of straw 22

[0070] In scenarios where temperature control is desired, the placement of disposable pods 42 at the bottom of the container 12 allows use with external heating accessories, such as heating pads or coasters 78. This allows for the maintenance or achievement of the desired brewing temperature with thermal efficiency. It is particularly advantageous for keeping hot beverages at an ideal warmth, or with a chilled coaster, imparting a cooling effect on cold brews.

[0071] The embodiment shown in FIGs 1, 2, and 4 is a single-sided pod piercing system, designed for simplicity and ease of use. Another embodiment shown in FIG. 9 features piercingson opposing sides of the pod 42 to facilitate the entry and exit of liquids, catering to specific user preferences and beverage types. Both configurations can benefit from the bottom-loading design.

[0072] The present disclosure can provide embodiments of a beverage container or portable beverage brewing system with at least the following features.1. A portable beverage brewing system, comprising: a) a container with an enclosed chamber for holding a liquid, forming a liquid reservoir; b) a receptacle located at the bottom of said container, beneath the liquid reservoir, adapted to receive a disposable pod containing beverage ingredients; c) an engagement mechanism within the receptacle for securing the disposable pod and creating a seal with said container; and d) means for piercing the disposable pod upon engagement to allow ingress and egress of the liquid to and from the pod, enabling brewing within the container.2. The engagement mechanism can be operable between a first position, in which the disposable pod is not engaged with the piercing means, and a second position, in which the disposable pod is engaged with the piercing means and the container is sealed.3. The system can further comprise a fluid communication channel, such as a straw, extending from the receptacle to an upper portion of the container, enabling the brewed beverage to be consumed directly from the container.4. The engagement mechanism can be manually operable via an external actuator on the container.5. The disposable pod can contain one or more of the following: coffee grounds, tea leaves, hot chocolate mix, vitamin supplements, flavors, fruit concentrates, mixers, or any combination thereof.6. The disposable pod can be configured to be pierced on two opposite sides for the ingress of a brewing liquid and the egress of the brewed beverage.7. The piercing on one side of the disposable pod is for the introduction of the brewing liquid and the piercing on the opposite side is for the dispensing of the brewed beverage into a consumption channel.8. The disposable pod can be configured to be pierced on one side for both the ingress of the brewing liquid and the egress of the brewed beverage, facilitated by a user-operated valve.9. The single-side piercing can be part of a streamlined brewing channel that optimizes the brewing process within the portable beverage system.10. The system can include a straw or channel allowing the user to apply negative pressure via suction to draw the brewed beverage from the pod, the negative pressure facilitating the flow of the beverage from the pod into the consumption channel.11. The system can include a straw or channel allowing the user to apply negative pressure via suction to draw the brewed beverage from the pod, the negative pressure facilitating the flow of the beverage from the pod into the consumption channel, said consumption channel enhancing user control over the strength of the brewed material to meet specific preferences, ranging from strong coffee to a lighter brew.

[0073] Referring to FIG. 10, the present disclosure can also provide a multi-chamber beverage container having a straw valve system applicable to the dilution and blending of concentrated liquids with diluents. It can provide an efficient and user-controlled means of mixing beverages to achieve desired concentrations and flavor profiles. This can be useful in the fields of consumer beverages, including but not limited to coffee, tea, soft drinks, alcoholic cocktails, and nutritional drinks, where the ability to customize the strength and taste of a drink on demand is desirable.

[0074] Other uses can be in the culinary arts for precision mixing of ingredients, in scientific research for combining reagents, and in various industrial processes where controlled mixing of fluids is required. The simplicity of design also allows for use in medical or therapeutic settings, where the accurate mixture of two or more drug, therapeutic or medical solutions can be necessary for patient care.

[0075] The present disclosure can provide a container 12 with an adjustable beverage mixing and drinking straw 22 with an integrated adjustable dilution or mixing twist valve 26. The straw 20 can permit the user to mix two or more liquids 50a and 52a housed in separate chambers 50 and 52 within a single container 12, allowing for real-time liquid ratio adjustment and customization of beverage strength and flavor. The twist valve mechanism 26 can be integrated with or into the straw 22.

[0076] By incorporating the mixing mechanism directly with or into the straw 22, it eliminates the need for additional utensils or external steps, offering a more streamlined and integrated experience. The user can conveniently adjust the beverage concentration or flavor by twisting the straw 22, which operates the built-in valve 26 to control the flow of liquids 50a and 52a from the chambers 50 and 52 into the straw 22 and subsequently into the mouth.

[0077] The twist valve 26 allows for control over the mixing process, and provide a variable setting that can be adjusted by the user to achieve a wide range of strengths and flavor profiles, from very mild to exceptionally strong, depending on the user's momentary requirements. Thiscan be accomplished without compromising the integrity of the container or the straw, maintaining a leak-proof and hygienic interface.

[0078] In addition to coffee, this can be used for other beverages such as tea, soft drinks, cocktails, and nutritional drinks. It is also applicable in various scenarios where precise mixing of consumables is desirable, such as in culinary arts, chemical laboratories, or healthcare settings where specific dilutions of a substance are needed.

[0079] The design is economical to manufacture, durable in use, and disposable or reusable as per the requirements of the user or the manufacturer. The simplicity of the design also lends itself to ease of cleaning, which is particularly advantageous for reusable models.

[0080] The present disclosure can also provide an adjustable beverage mixing straw with a built-in twist valve that enables the selective mixing of two or more liquids from separate chambers within a single container.

[0081] The container can be adaptable to multiple chambers, employing the same mechanical twist logic for the valve mechanism across various chamber configurations.

[0082] The container 12 can have a first or upper liquid reservoir or chamber 50 containing a first type of liquid 50a that can be mixed using the straw 22.

[0070] A second, bottom or lower liquid reservoir or chamber 52 can be below chamber 50 and contain a second type of liquid 52a, for mixing with the first type of liquid 50a.

[0083] A vent hole 54 for chamber 52 can allow air to enter the chamber 52 to facilitate the flow of the second type of liquid 52a into the straw 22 when suction is applied to the opening 60 of the straw 22.

[0084] The straw 22 can be connected to or be part of a valve 26 that permits the contents from bottom chamber 52 to enter the straw 22. This is indicated by the dotted arrows 56, which represent the flow of liquid 52a when negative pressure is applied within the straw 22. The valve 26 can be integrated into or connected to the straw 22 such that when the straw 22 is twisted, it can adjust, open or close the valve 26 based on the twist direction, allowing adjusting flow or stopping liquid 50a from upper chamber 50 to enter the straw 22.

[0085] The user can twist or rotate the straw 22 to adjust the mixing ratio of the two liquids 50a and 52a in chambers 50 and 52.

[0086] Straw 22 has a tip, opening or an exit passage 60 at which negative pressure is applied by the user, typically with the mouth via suction, to draw the liquids into the straw for consumption.

[0087] Straw 22 can extend into a segmented container 62. The container 62 can be partitioned into multiple chambers 50 and 52, each designated to hold two distinct liquid types50a and 52a. The straw 22 can be connected to or integrated with a twist valve mechanism 26, that can modulate the ingress of liquid from these chambers 50 and 52.

[0088] The valve mechanism 26 can be actuated by the user's rotational manipulation of the straw's 22 upper section 21, as indicated by arrows 22a. This rotation can cause alignment or misalignment of the valve’s 26 or straw's 22 orifices or apertures 32 and 26d that are in fluid communication with the respective chambers 50 and 52. Apertures 26d can increase in size moving along a desired arc length for incrementally changing flow rate. Through this interaction, the user can dictate the liquid flow into the straw 22, enabling a personalized mix and ratio of the consumed liquids.

[0089] With a simple twist of the straw's 22 upper section 21, a user can opt for a dominant flow from one chamber, thus intensifying a particular flavor, or synchronize the openings to amalgamate the liquid contents. This functionality extends to the complete occlusion of flow from any chamber, should the user's preference so dictate.

[0090] The user can initiate the device by applying a suction force to the opening 60 of the straw 22, inducing a negative pressure environment within the straw 22. This vacuum effect propels the liquid 52a ascent from the lower chamber 52 through the upper chamber 50. Subsequently, the user can rotate the straw 22 to a specific orientation of valve 26, to curate the liquid blend. The vent hole 54 allows air to replace the dispensed liquid 52a, negating the formation of a vacuum that could otherwise hinder the beverage flow.

[0091] One example of an application within the coffee sector can involve chamber 50 housing a robust coffee concentrate, while chamber 52 can be filled with water, milk, or an alternative diluent. Users can calibrate the straw 22 to fine-tune their coffee to a preferred potency, ranging from a diluted mildness to an intensified robustness, all achievable in the act of drinking.

[0092] The present disclosure can provide embodiments of an adjustable dilution valve in a beverage container or an adjustable beverage mixing straw apparatus with at least the following features.1) An adjustable beverage mixing straw apparatus, comprising: a) a straw with a built-in twist valve mechanism. b) multiple chambers within a single container, each chamber configured to hold a separate liquid; and c) means for selectively controlling the flow of liquid from each chamber into the straw via the twist valve mechanism in response to user manipulation.2) The twist valve mechanism can be capable of variably aligning with openings corresponding to each chamber to control the flow rate of liquid from the chambers into the straw.3) The straw can allow a user to adjust the ratio of liquids from the chambers in real-time during consumption.4) The chambers can hold liquids of differing viscosities and densities.5) The vent holes associated with each chamber can facilitate the flow of liquid into the straw when negative pressure is applied.6) The twist valve mechanism can be integrated into the straw such that rotation of the straw with respect to the container opens or closes fluid communication between the chambers and the straw.7) The straw and the twist valve mechanism can maintain a leak-proof seal during operation.8) A method for mixing beverages, the method comprising: a. providing a container with multiple chambers, each containing a different liquid; b. inserting the straw with the built-in twist valve into the container; c. applying suction to the straw to draw liquid from the chambers; and d. twisting the straw to adjust the flow of liquids from the chambers into the straw, thereby mixing the liquids in a desired ratio.9) Twisting the straw can adjust the ratio of liquids from the chambers in real-time as the user consumes the beverage.10) A beverage mixing system for customizing the strength and flavor of a beverage, the system comprising: a. a container with multiple chambers for holding different liquids; b. a straw with an integrated twist valve for drawing liquids from the chambers; and c. a user interface for adjusting the position of the twist valve to control the mixing ratio of the liquids.

[0093] The present disclosure can provide an adjustable beverage mixing straw featuring an integrated twist valve mechanism, designed for the selective combination of two or more liquids from distinct chambers within a single container. The straw can allow for the real-time adjustment of the mixing ratio of liquids, thereby enabling users to customize the strength and flavor of their beverage at-the-point of consumption. The twist valve, operated by the rotation of the straw, can control the flow from each chamber, The device is particularly advantageous in settings where beverage customization is desired, such as in the coffee industry but not limited,where users may prefer varying coffee concentrations. The simplicity of the design facilitates ease of use and hygiene, suitable for both disposable and reusable applications, and can be adapted for a wide range of beverages, including but not limited to coffee, tea, vitamin supplements, mixer, fruit concentrates, mocktails, and cocktails. The adjustable beverage mixing straw simplifies the traditional beverage mixing process, eliminating the need for additional processes, procedures, etc.

[0094] Further details of embodiments of the present disclosure follow. Referring to FIGs. 1, 2 and 4, the beverage container 10 is designed for use while in a generally upright position or orientation. The shell 12 can be generally cylindrical in shape and include a removable top cover 24 through which the drinking straw 22 extends, and an open bottom. A generally cup shaped chamber, partition, wall or socket member 17 having a lower cylindrical wall 17a and an upper wall 17b can be fitted into the bottom of the shell 12 and sealed to the interior of the shell 12, to form the liquid or water reservoir 18 within the shell 12 above the upper wall 17b. Liquid entry flow channel 20 can extend through a channel member 20a that is connected, attached, fitted and / or sealed or formed to wall 17b, allowing liquid or water 18a from liquid reservoir 18 to enter, and can further extend in a continued channel 30 through a liquid entry flow needle 38 that can be connected to channel member 20a, allowing liquid or water 18a to enter the additive compartment 16 downwardly by gravity for brewing or mixing to form a brewed beverage or mixed liquid 35. The continued channel 30 in some embodiments can be considered part of the liquid entry flow channel 20. The needle 38 can have openings 38a near the downwardly directed tip. The channel member 20a, liquid entry flow channel 20, channel 30 and needle 38 can extend or be aligned along a liquid entry flow axis B. The channel member 20a can have a protrusion or lip 20b extending above the liquid entry flow channel 20 to form a lateral or side entrance into the flow channel 20.

[0095] A channel member 28a can be connected, attached, fitted and / or sealed to or formed in wall 17b in a position laterally spaced apart from channel member 20a. A mixed liquid exit flow needle 40 can be connected to channel member 28a. Brewed or mixed liquid 35 exiting the additive compartment 16 can enter openings 40a of needle 40 that are near the downwardly directed tip of needle 40, and flow upwardly with suction on the drinking straw 22 along a brewed or mixed liquid exit flow channel 28 extending through needle 40. The adjustable dilution valve 26 can be connected to the channel member 28a in a sealed manner, and the drinking straw 22 can be rotatably coupled to the adjustable dilution valve 26 about a longitudinal rotational axis A. The drinking straw 22, the adjustable dilution valve 26, the channel member 28a, the mixed liquid exit flow channel 28 and the needle 40 can be alignedalong the longitudinal rotational axis A. Channel member 20a, liquid entry flow channel 20, channel 30, needle 38 and liquid entry flow axis B, can be parallel to and laterally spaced apart from drinking straw 22, adjustable dilution valve 26, channel member 28a, mixed liquid exit flow channel 28, needle 40 and longitudinal rotational axis A. Axes A and B can be parallel to and on opposite sides of the central axis C of the beverage container 10. In some embodiments, needles 38 and 40 can be connected to and sealed respectively to channel member 20a channel member 28a, and in other embodiments can be formed integrally therewith.

[0096] A generally cup shaped socket insert member 15 can be coupled and sealed to and within socket member 17. The lower cylindrical wall 15a of socket insert member 15 can engage or nest against the lower cylindrical wall 17a of socket member 17, and the needles 38 and 40 can extend downwardly through or from the upper wall 15b of socket insert member 15 in a sealed manner, thereby extending downwardly into the interior 74 of socket insert member 15. Two sealing arrangements 80 can be positioned on the lower surface of the upper wall 15b of socket insert member 15, for surrounding and sealing around respective needles 38 and 40 and against the top surface of the membrane seal 42a of a disposable additive pod 42 (FIGs. 5 and 6) when contained within a receptacle 70 locked in the interior of socket insert member 15. The sealing arrangements 80 can include two concentric O-ring seals 80a encircling respective needles 38 and 40 about axes B and A. In some embodiments, the sealing arrangements 80 can include other suitable sealing members such as flat washers.

[0097] The receptacle 70 can include an interior 70a for shaped for holding the pod 42 in a manner where the membrane seal 42a extends over the top of the receptacle 70. The lower portion of the receptacle 70 can include two engagement mechanisms 72 on opposite sides, such as locking protrusions for removably engaging respective recesses or openings 17c within opposite sides of the lower cylindrical wall 17a of socket member 17 for locking the receptacle 70 and pod 42 within the interior of socket insert member 15 when inserted in an upward motion in the direction of arrow 9. Tabs 76 connected to the engagement mechanisms 72 can be used to help resiliently move or deform the mechanisms 72 inwardly towards each other for locking and unlocking the receptacle 70. When the receptacle 70 containing a pod 42 is inserted upwardly into the interior 74, the two downwardly extending needles 38 and 40 can simultaneously pierce the membrane seal 42a of pod 42 for extending into the pod 42, and the sealing arrangements 80 can seal against the membrane seal 42a around the needles 38 and 40. FIGs. 7 and 8 show the appearance of an embodiment of where the receptacle 70 is locked to the bottom of the shell 12

[0098] Referring to FIG. 2, embodiments of the adjustable dilution valve 26 can include a generally annular inner valve member 26b and having an inner flow channel 26c extending alongthe longitudinal rotational axis A in fluid communication with mixed liquid exit flow channel 28. The inner valve member 26b can have a series of fluid flow openings, orifices, passages or apertures 26d extending laterally through the side wall of the inner valve member 26b to the inner flow channel 26c. The apertures 26d can have an increasing aperture size moving along a desired arc length of the periphery of the inner valve member 26b. The apertures 26d can be upright slots of increasing or differing lengths as shown, or can have differing circular hole sizes. At least a portion of the periphery can be absent of apertures 26d. A mating outer valve member 26a can be rotatably mounted or coupled to or around the inner valve member about the longitudinal rotational axis A. The outer valve member 26a can have at least one lateral fluid flow opening, orifice, passage or aperture 32 extending through the side wall from the liquid reservoir 18 to the inner valve member 26b, which allows fluid flow to the inner flow channel 26c via apertures 26d. In some embodiments, outer valve member 26a can have two apertures 32 on opposite sides. The outer valve member 26a can also be rotatably mounted about channel member 28a, and sealed at the bottom with an O-ring seal 82 therebetween. The drinking straw 22 can be coupled to an upper portion of the outer valve member 26a within a coupling sleeve 26e. In some embodiments, the drinking straw 22 can be removably coupled to the sleeve 26e and valve 26. Rotation of the drinking straw 22 rotates the outer valve member 26a relative to the inner valve member 26b, for aligning the apertures 32 of the outer valve member 26a with selected sized apertures 26d of the inner valve member 26b for controlling the flow of liquid or water 18a from the liquid reservoir 18 into the inner flow channel 26c. In certain positions, the apertures 32 of the outer valve member 26a can be positioned out of alignment with the apertures 26d to prevent flow of liquid 18a into the inner valve member 26b from the outer valve member 26a. In some embodiments, the inner valve member 26b can be formed on an upper end of needle 40 or channel member 28a. In some embodiments, the series of apertures 26d can be positioned on the outer valve member 26a, and the apertures 32 can be on the inner valve member 26b. In other embodiments, the inner valve member 26b can be attached to and rotated by the drinking straw 22 about axis A.

[0099] In an example of use, the liquid reservoir 18 can be filled with a liquid such as water 18a with the top cover 24 removed. In some cases, the water 18a can be hot. Once the top cover 24 is replaced, a pod 42 containing an additive or material 16a such as coffee, can be inserted into the interior 70a of the receptacle 70. The receptacle 70 is inserted upwardly in the direction of arrow 9 into the bottom of the shell 12 into the interior 74 of the socket insert member 15 and locked in place, causing the needles 38 and 40 to downwardly pierce the membrane seal 42a of the pod 42 and extend into the pod 42. Needle 38 extends into the beverage additive or material,or coffee 16a, and needle 40 can extend into an open or empty region 42c of the pod 42 that is free of material 16a. Water 18a from the bottom of liquid reservoir 18 flows downwardly by gravity into liquid entry flow channel 20 shown by arrow 44a, vertically through needle 38, and out of openings 38a into the coffee 16a within pod 42 as shown by arrow 44b. The water 18a saturates the coffee 16a, mixing with or brewing, and forms a brewed or mixed beverage or liquid 35 in a first beverage preparation stage, that flows laterally into the open region 42c. The first stage in some embodiments can be considered a first priming, brewing, mixing or dilution stage. The water 18a in the liquid reservoir 18 can be hot water for conducting the brewing process, or the water 18a can be cold and the beverage container 10 can be placed upon a hot plate 78 (FIG. 4), where the bottom 42b of the pod 42 can be in thermal contact with the bottom of the receptacle 70, which contacts the hot plate 78 for heating the water 18a within pod 42 for brewing. The brewed or mixed beverage 35 can enter the needle 40 via openings 40a into the mixed exit flow channel 28 as shown by arrows 44c and 44d when suction is applied to the drinking straw 22, moving vertically upward. As the brewed or mixed beverage 35 reaches the adjustable dilution valve 26, the user can rotate the valve 26 with drinking straw 22 about axis A as indicated by the arrows 22a, to select the desired amount of water 18a from the bottom of liquid reservoir 18 to laterally enter or pass through apertures 32 in the outer valve member 26a as shown by arrow 44e and through selected apertures 26d in the inner valve member 26b, into the inner flow channel 26c for mixing and diluting the brewed or mixed beverage 35 entering drinking straw 22 to form a final diluted beverage 36 in a second beverage preparation stage. The second stage can be considered in some embodiments a second mixing or dilution stage. The final diluted finished beverage 36 can be consumed from the drinking straw 22 as indicated by arrow 44f. If no dilution is desired, the user can rotate the valve 26 into a closed position, whereby the brewed or mixed beverage 35 can be the final beverage 36. In some embodiments, brewing can be conducted with cold water 18a for obtaining a cold beverage.

[0100] In embodiments of the beverage container 10, the beverage material or additive compartment 16 can include the receptacle 70 and / or the pod 42. In some embodiments, the receptacle 70 can contain loose additive or material 16a, or a flexible pouch containing material 16a. In some embodiments, the socket member 17 and / or socket insert member 15 can be considered part of the beverage material or additive compartment 16. In some embodiments, the additive or material 16a can be herbal or medicinal materials.

[0101] FIGs. 11-15 show another embodiment of adjustable dilution valve 26. The inner valve member 26b can extend upwardly from needle 40, channel member 28a, and upwardly from the upper wall 17b of socket member 17, along the longitudinal rotational axis A. Themixed exit flow channel 28 can extend through needle 40 to connect with the inner flow channel 26c of the inner valve member 26b. The inner flow channel 26c of inner valve member 26b can have a flared or widening portion 28b extending from the mixed exit flow channel 28, and can have angled sides of about 45 degrees on each side of axis A, before connecting with a widened mixing chamber 28c. The flared portion 28b can promote an expansion of the diameter of the inner flow channel 26c entering the mixing chamber 28c. The diameter of the mixing chamber 28c can be at least a ratio of 3 : 1 greater than the diameter of the mixed exit flow channel 28. The inner valve member 26b can have a generally cylindrical annular sidewall with two fluid flow openings, passages or apertures 32 extending laterally therethrough on opposite sides, into the mixing chamber 28c near the upper wall 17b. A seal 82 such as an O-ring 82 can extend around the perimeter of the inner valve member 26b against the upper wall 17b and below the apertures 32. A male screw thread 27b can extend around the perimeter of the inner valve member 26b above the apertures 32. The outer valve member 26a can be coupled to drinking straw 22 by coupling sleeve 26e. The outer valve member 26a can have a cylindrical annular sidewall 29a that can be positioned radially outward from coupling sleeve 26e by a lateral portion 29b. The interior of the annular sidewall 29a can have a female screw thread 27a that mates and engages with the male screw thread 27b on the inner valve member 26b for rotatably coupling the outer valve member 26a to the inner valve member 26b.

[0102] Referring to FIG. 14, the outer valve member 26a is shown in a position where the bottom edge of the outer valve member 26a is above the apertures 32 of the inner valve member 26a, allowing the flow of liquid or water 18a to flow through apertures 32 into mixing chamber 28c as indicated by arrow 44e for mixing with brewed or mixed liquid 35 for dilution. Rotation of the drinking straw 22 in the direction of arrows 22a can rotate the outer valve member 26a about the longitudinal rotational axis A relative to the inner valve member 26b, which due to the screw threads 27a / 27b, can move the axial position of the outer valve member 26a in the direction of arrows 23 relative to the inner valve member 26b and the apertures 32. As a result, the outer valve member 26a moves both rotationally about and axially along the longitudinal rotational axis A. The axial movement of outer valve member 26a can cause incremental uncovering or covering of the apertures 32 by the outer valve member 26a for incrementally increasing or decreasing flow of liquid or water 18a through apertures 32. The downstream end of the flared portion 28b of the inner flow channel 26c intersects with the apertures 32, so that the diluting liquid 18a entering the widened mixing chamber 28c through the apertures 32 mixes with the brewed or mixed liquid 35 as the flow of the liquid 35 is laterally widening in flow, thereby promoting more thorough mixing for better taste results of the final diluted beverage 36.When the outer valve member 26a is moved axially downward so that the bottom surfaces engage seal 82 or O-ring, the fluid path to the apertures 32 is closed off, thereby preventing dilution of the brewed or mixed liquid 35.

[0103] Although the different embodiments of beverage containers shown and described can have different adjustable dilution valve embodiments, it is understood that other suitable valves can be interchangeably used in the various embodiments of the beverage containers.Additionally, the valves 26 shown in FIGs. 2 and 11-15 can also be used in the beverage container of FIG. 10. In some embodiments of the beverage container of FIG. 10, the lower chamber 52 can accept a pouch or pod 42 filled with liquid 52a which is pierced by a protrusion extending downwardly from valve 26. Although liquids 18a such as water has been described for use, in other embodiments, alcoholic liquids can also be used.

[0104] While example embodiments have been particularly shown and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the scope of the embodiments encompassed by the appended claims. For example, features of the various embodiments can be omitted or combined together. Embodiments of the present disclosure are described while in an upright position, since that is generally the position during use, but it is understood that other orientations are possible.
