1. An additive delivery system comprising:
a cap base for securing the additive delivery system to a base fluid container;
a mixing nozzle cooperatively associated with the cap base for facilitating the mixing of additive with the base fluid, the mixing nozzle including a mixing nozzle additive passage extending through the mixing nozzle from a reservoir receiving end of the mixing nozzle to an opposite, metering end of the mixing nozzle;
the mixing nozzle including a first metering surface proximate the metering end of the mixing nozzle,
the mixing nozzle further including at least one mixing nozzle base fluid passage defining at least one respective base fluid flow path through the mixing nozzle, the at least one respective base fluid flow path being separate from the additive flow path such that base fluid and additive flow in separate paths through the mixing nozzle;
a metering component cooperating with the mixing nozzle, the metering component having a second metering surface that defines, with the first metering surface, a variable flow passage;
an additive adjustment actuator cooperating with the cap base for movement relative thereto, the additive adjustment actuator also cooperating with the metering component such that movement of the additive adjustment actuator causes movement of the second metering surface relative to the first metering surface; and
a reservoir assembly receiving structure disposed on the reservoir receiving end of the mixing nozzle for receiving a reservoir assembly.
