Abstract
A volatile substance delivery system includes a volatile substance container to contain a volatile substance, an optional absorbent and collapsible element disposed within the container to reduce presence of undesired air during manufacture of the device, an outlet to deliver a volume of the volatile substance from the volatile substance container toward an ambient environment, and a manual screw pump to reduce volume (or sometimes, just increase pressure) within the volatile substance container and promote the delivery of the volatile substance from the volatile substance container. A safety chamber is sometimes provided to resist unintended escape of volatile substance in liquid phase to the environment.
