Abstract
Dispenser systems, dispensers, and repositories can add a fragrance to an unscented liquid beauty preparation. The dispenser system includes a dispenser having a cavity for retaining at least a first liquid, and a repository configured for removably attaching to the dispenser, the repository having a reservoir for retaining at least a second liquid. The dispenser is coupled with a pump assembly including at least one pump for drawing the at least a first liquid and the at least a second liquid into a mixing chamber. The mixing chamber is coupled with an actuator in such a manner that when the actuator is pressed down by an external force, the mixing chamber communicates with the pump to suction the first and second liquids into the mixing chamber to form a liquid mixture for dispensing through a nozzle.
