Beschreibung
Zusammenfassung:	An indicator system with a dispenser providing controlled release of a volatile material contained within a dispenser, which indicates the exhausti on of the volatile material. The dispenser includes a blister that contains a vapor permeable membrane that collapses on a bottom wall due to internal vacuum forces created by the evacuation of volatile material. As the membran e collapses the remaining volatile material migrates to the periphery of the dispenser thereby indicating exhaustion of the volatile material.
