Definitions
- the disclosure relates to dispensing and delivery systems for beverages and other products.
- the disclosure further relates to dispensing and delivery systems in which an additive, such as flavorings, concentrates or supplements, may be provided in replaceable cartridges and mixed with a base fluid, such as water, as the base fluid is dispensed and/or consumed from a container and wherein one-way flow of base fluid is provided to prevent additive from mixing with the base fluid supply, which may thus be used with different additive delivery systems.
- the disclosure further relates to dispensing and delivery systems and additive delivery systems that provide for user adjustment of the amount of additive that is mixed with the base fluid.
- the disclosure further relates to reservoir assemblies for storage of additives and for use in such additive delivery systems, and to methods for making and using such systems.
- the prior art includes various devices for providing additives to a base liquid.
- Such devices include pre-mix systems, such as those described in U.S. Pat. No. 7,306,117, in which a predetermined amount of additive is dispensed into a base liquid within the container and mixed therewith prior to consumption.
- Prior art systems also include devices in which an additive is provided to a base fluid as it is dispensed from a container.
- Such delivery systems are exemplified by U.S. Pat. No. 8,230,777, which describes a dispensing system in which a base liquid flows through a supplement area containing solid supplements, and U.S. Pat. No. 8,413,844, which describes a water dispenser (pitcher) having a filter and an additive chamber in which the additive is dispensed as water is poured from the dispenser.
- an additive delivery system may incorporate a cartridge system, including a container cap and an additive reservoir assembly that provides for storage of an additive.
- the container cap may be secured to a base fluid container.
- a mixing nozzle is cooperatively associated with the container cap for mixing of the additive with a base fluid as the base fluid flows from the base fluid container through the cartridge.
- a one-way valve prevents backflow of base fluid and/or mixed base fluid/additive from an area downstream of the mixing nozzle such that the base fluid supply remains in a pure state.
- this feature permits a given additive to be used with a given supply of base fluid without requiring the entire supply of base fluid to be used or consumed in a mixed state. A leftover supply of base fluid may remain unmixed and used in other applications, such as with other flavorings or supplements.
- the additive delivery systems enable more efficient use of both additive and base fluid.
- an additive delivery system may incorporate a cartridge system and provide for adjustable flow of additive and adjustable mixing of additive with a base fluid as the base fluid flows through the additive delivery system.
- An adjustment actuator may be moved by a user to cause a corresponding adjustment in valve components incorporated into the additive delivery system.
- the valve components may include a metering component, which may have a conical portion that cooperates with a mixing nozzle having a correspondingly shaped seat to provide precise control of additive flow. Movement of the adjustment actuator by a user results in movement of the metering component in precise fashion to increase or decrease the flow of additive that occurs when base fluid is dispensed through the cartridge.
- Indicia may be included to indicate relative degrees of additive flow and mixing to the user. This feature permits a user to achieve a desired and repeatable mixing proportion of additive to base fluid.
- an additive delivery system may utilize a cartridge system that provides improved flow geometries that enhance mixing of additive and base fluid as the additive and base fluid flow from the cartridge.
- Such flow geometries may include a central flow component for the additive and a surrounding or radially displaced flow component for the base fluid. They may also include one or more convergence zone in the additive flow path.
- geometries may also be used in conjunction with one or more agitating or turbulence creating elements incorporated into a dispensing spout downstream of a mixing area in the cartridge assembly to further enhance the mixing of the additive and base fluid prior to use or consumption.
- Such flow geometries and agitating or turbulence creating elements provide for thorough mixing of additive and base fluid.
- a reservoir assembly for use with an additive delivery system and cartridge may include a flexible reservoir such as a pouch, bag, bladder or other flexible reservoir structure.
- This reservoir assembly structure provides improved flow and mixing characteristics by reducing or
- a protective cage or solid walled protective housing may enclose the reservoir to protect it during sale/shipping.
- such flexible reservoir structures may also permit external pressure to be applied to the additive reservoir, such as pressure created when a user squeezes or otherwise applies pressure to a container, i.e., water bottle, in which the cartridge is housed. This interaction between the flexible cartridge reservoir structure and the interior conditions may facilitate more uniform or consistent dispensing of additive from the cartridge and more uniform mixing with a base fluid.
- a cartridge assembly is packaged and distributed as a unit that includes a reservoir assembly and adjustable mixing cap, such that the cartridge assembly may be installed on a user's own bottle of base fluid, such as a water bottle purchased separately.
- a frangible protective outer safety membrane such as a shrink wrap, or foil pouch, may seal the entire cartridge assembly package for quality and safety control.
