Abstract
An additive delivery system may incorporate a cartridge system, including a container cap and a reservoir assembly that provides for storage of an additive. The container cap includes a mixing nozzle 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.

A method of assembly for an additive cartridge for adding additive to base liquid, the method comprising:
- providing a cartridge base having an attached mixing nozzle, a metering valve threadedly engaged with the mixing nozzle and an adjustment actuator configured to rotate the metering valve relative to the mixing nozzle and adjust a size of an additive flow path of the mixing nozzle in response to rotation of the adjustment actuator, the cartridge base configured to secure the additive cartridge to a base liquid container;
- filling a flexible pouch of a reservoir assembly with a liquid additive;
- and
- securing the reservoir assembly to the mixing nozzle such that the flexible pouch is in fluid communication with the additive flow path of the mixing nozzle.
A reservoir assembly for use with an additive cartridge configured to provide additive to a base liquid, the assembly comprising:
- a spout including an adapter portion configured to sealingly engage with a flexible pouch and a stem including a ridge configured to engage with retaining arms of a mixing nozzle of the additive cartridge to secure the reservoir assembly to the additive cartridge;
- and
- the flexible pouch sealingly engaged with the adapter portion and configured to hold a liquid additive,
- wherein the spout is configured to fluidly couple an interior space of the flexible pouch with the mixing nozzle.
A method of assembly for reservoir assembly for use with an additive cartridge configured to provide additive to a base liquid, the method comprising:
- providing a spout including an adapter portion configured to sealingly engage with a flexible pouch and a stem including a ridge configured to engage with retaining arms of a mixing nozzle of the additive cartridge to secure the reservoir assembly to the additive cartridge;
- providing a liquid additive into an interior space of the flexible pouch;
- and
- securing the flexible pouch to the adapter portion of the spout to fluidly couple the interior space of the flexible pouch to the stem.
