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.

1-20. (canceled)
A method of assembling an additive cartridge comprising:
- providing a cap base, the cap base being adapted to be secured to a base fluid container;
- arranging a mixing nozzle in a predetermined nozzle rotational position relative to the cap base, the predetermined nozzle rotational position being required for engagement of the mixing nozzle with the cap base;
- positioning an additive flow metering insert on the mixing nozzle;
- and
- securing an additive adjustment actuator to the cap base.
A method of assembling an additive cartridge comprising:
- providing a cap base, the cap base being adapted to be secured to a base fluid container;
- arranging a mixing nozzle on the cap base;
- positioning an additive flow metering insert in a predetermined insert rotational position on the mixing nozzle, the additive flow metering insert defining an adjustable flow passage with the mixing nozzle, and the predetermined insert rotational position being required for engagement of the additive flow metering insert with the mixing nozzle;
- and
- securing an additive adjustment actuator to the cap base.
An additive cartridge comprising:
- a cap base adapted to secure the additive cartridge to a base liquid container;
- an additive reservoir holding an additive and attached to the cap base;
- a dispensing spout configured to dispense base liquid mixed with the additive;
- a base liquid flow path extending through the additive cartridge to the dispensing spout;
- an additive flow path extending from the additive reservoir to the base liquid flow path;
- a metering component arranged to adjust an amount of additive mixed with the base liquid as the base liquid flows through the additive cartridge;
- and
- an adjustment actuator adapted to permit a user to adjust the metering component.
