ABSTRACT:
The disclosure is directed to a novel method of forming and packaging for display hollow, solid space air treating devices. A molten treating composition is charged into the outer shell of a thermoformed container which serves as a mold, as well as a display package for the finished product. An inner core is placed inside the outer shell displacing the molten material and forming a chamber of the shape and size of the device. A gas equalizing aperture permits release of internal pressure and excess molten material. The filled mold is cooled. The sealed container is suitable for shelf display but may have additional trade dress applied, if desired. The ultimate user removes the outer shell from the solidified device to activate the space air treatment feature.
