Abstract

A dispensing system includes a refill having a reservoir for containing a volatile material. A permeable membrane is disposed over the reservoir and allows the volatile material to be released therethrough. The dispensing system also includes a housing adapted to retain the refill and a manual drive mechanism, which is in communication with the refill. Actuation of the manual drive mechanism causes the refill to rotate more than 180° about a longitudinal axis.
