ABSTRACT:
An air-freshener package activated by microwave energy to discharge into the atmosphere an aromatic vapor comparable to that exuded by a potpourri. The package comprises a container formed of thermal insulation material permeable to microwave energy and having a vent therein. Stored in the package is a porous pad impregnated with a liquid fragrance which simulates the aroma of a natural potpourri. When the package is irradiated in a microwave oven, the liquid fragrance is then heated to a level causing it to volatilize to generate an aromatic vapor. This vapor is discharged into the atmosphere through the vent when the package is removed from the oven and placed in a room. The temperature level is substantially maintained for a protracted period by the thermal insulation so that the aromatic vapor suffuses the room.
