ABSTRACT:
A dispenser for controlling the release of volatile materials within a contained environment such as an automobile, a home, an office, a factory, or the like, comprises a housing having an opening therein, a volatile material positioned within the housing, and a temperature responsive component in operable association with the opening to regulate said opening in order to contain or release the volatile material. The temperature responsive component automatically controls the release of the volatile material in the contained environment in response to a change in the ambient temperature by uncovering or covering the opening of the housing. A method for controlling the release of volatile materials within a contained environment is also disclosed.
