ABSTRACT:
A dispensing device (7) that is intended to be mounted on a vertical planar surface such as a door (10). The dispensing device (7) includes an enclosure (13) having a first opening (34) and a second opening (37) defined therein. The first opening (34) contains a first airflow valve (43) and the second opening contains a second airflow valve (46). An odorous substance (40) is disposed inside the enclosure (13) between the two airflow valves (43,46). When the door (10) swings open or closed, airflow generated along the surface of the door (10) passes through the airflow valves (43,46) to release the odors from the odorous substance (40) into the area surrounding the door (10).
