Abstract: A mixing cartridge delivery system, which mixes additive with base liquid flowing through it, utilizes a dispensing closure valve to achieve improved flow of mixed liquid from the cartridge. A closure base may include a tethered lid. A flexible valve, such as a slit valve, is supported on a valve supporting end of the closure base and retained thereon with a valve retainer that interlocks with the closure base. The system may include a one-way valve for base liquid and a mixing section defined in the cartridge. The dispensing closure valve achieves improved flow characteristics in combination with the base liquid valve. The dispensing closure valve also prevents leakage and inadvertent discharge from the cartridge system.

Abstract: A portable carbonating dispenser utilizes an onboard supply of carbonation gas and a carbonation control module for permitting a user to carbonate base liquid stored in an onboard base liquid container. The carbonation control module may include a user actuated button for selectively activating the carbonation. The base liquid container may include an extended portion for increasing the exposure of base liquid to carbonation gas. A vertical viewing window enables a user to view carbonation and the level of base liquid in the container. An isolation component may be useful to isolate an additive cartridge from carbonation pressure during carbonation in applications where the dispenser utilizes additive cartridges. Safety venting and locking features may be provided on the mode selector to prevent a user from accidentally pressurizing the cartridge space. A refill station may be provided to refill the portable carbonating dispenser.

Abstract: A filtration system is adapted for use and integration with cartridge-based beverage dispensing systems that mix an additive (flavor) with a base liquid (water) as the base liquid is dispensed from a container and through the cartridge. A support frame may support an annular charcoal fabric filter element secured with an end cap and defining an inner cavity to house and surround a portion of the cartridge. A filter cage may enclose the filter element. The support frame may include a bayonet-type connector to secure the filter assembly to a container lid. Base liquid flowing from the container and through the cartridge necessarily flows first through the filter element as a user drinks from the container. Related methods for assembling the filter assembly and installing the filter assembly on a cartridge/lid assembly are also disclosed.
