Abstract

A delivery apparatus includes a volatile agent source, a controller, and an emanator material. The volatile agent source stores a volume of a volatile agent such as a fragrance. The volatile agent source includes an outlet for delivery of the volatile agent from the volatile agent source. The controller controls a delivery rate of the volatile agent from the volatile agent source. The emanator material is disposed at approximately the outlet of the volatile agent source. The emanator material absorbs at least a portion of the volatile agent and maintains the volatile agent until the volatile agent evaporates into an ambient environment.
