Abstract
Abstract A frusto-pyramidal carton for holding an insert of air freshener material includes a bottom wall panel and a number of side wall panels which converge toward one another as they extend away from the bottom wall panel. A top wall panel connects the upper edges of the side wall panels. Air circulating openings are formed in the top wall panel and side wall panels. A cake of air freshener material is trapped between the bottom wall panel and a retaining panel which is slightly larger than the top wall panel but slightly smaller than the bottom wall panel. The retaining panel limits displacement of the air freshener material even if the carton is inverted.
