Abstract
Abstract An air freshener carton includes a regular, polygonally-shaped lower unit and a complementally shaped upper unit which are movable relative to each other along a common, longitudinal axis. The upper unit has a plurality of openings spaced about its top wall which are selectively opened by relative movement of the units away from each to enable air to circulate through the openings to contact and diffuse an active air freshener material housed within the lower unit.
