Abstract: A passive vapor dispersing device which may be used for freshening or otherwise treating the air, characterized by both rapid and substantially linear delivery of volatizable fragrance or other materials. The device uses a packaged combination of liquid reservoir, wick and emanator which is assembled and shipped with the wick and emanator out of contact with each other, but is activated when the user opens the package and places the wick and emanator in contact. The housing for the device provides guide means for assisting the user in placing the wick and emanator in proper contact, and irreversible lock means for holding the components in contact and preventing access to the wick and emanator once activation has been achieved.
