Abstract
A device for dispensing a vaporizable material including a base adapted to support thereon an air freshener element and adapted to be supported on a pivotable door, a cover supported on the base and cooperating with the base to define an air passage communicating with the air freshener element, guide rails for affording selective movement of the cover relative to the base between a closed position wherein the air passage is substantially obstructed by a baffle and an open position wherein the device promotes passage of a flow of air through the passage during pivotal movement of the door, and detents on the base and cover which cooperate to retain the relative position of the cover and base during pivotal movement of the door.
