Abstract
A wick assembly is provided for use in a dispensing device that dispenses volatile material from a wick by heat. Two wick sections of differing material are provided in stacked fashion, with a coupler sleeve that can be used to facilitate attachment of the wick structure to a reservoir. One wick section preferably provides control over the rate of dispensing, where the other provides improved thermal resistance and resistance to clogging.
