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.
Claims22
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 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 such that the additive adjustment actuator may be rotated relative to the cap base, and such that rotation of the additive adjustment actuator causes the flow metering insert to move relative to the mixing nozzle to thereby adjust the adjustable flow.
