ABSTRACT:
Described is an air freshener unit comprising a container, a disc-shaped cartridge of air freshening material rotatably mounted about a horizontal axis within the container, and a discharge outlet in the wall of the container to allow the air freshening vapor to be dispensed. The container has baffle means adapted to allow a faster rate of evaporation of the air freshening material in one part of the cartridge relative to the remainder of the cartridge. The quicker rate of evaporation of the offset part causes the center of gravity to self-rotate within the container. The disc-shaped cartridge comprises a holder having a hub portion for rotatably mounting the cartridge in the container and holding means for supporting air freshening material in block form uniformly around the hub portion. The hub portion has oppositely directed stub shafts for location in apertures in opposed walls of the container, the apertures allowing the cartridge to rotate.
