Abstract
Abstract A free-standing package of the blister type includes an article containing enclosure formed of a single piece of self-supporting plastic material. The enclosure is in two mating sections integrally joined along a fold line traversing what becomes the base of the completed package. The free edges of the sections have flanges which meet when the sections are closed to envelop the article and the sections are sealed together along the flanges. At the same time, the initially folded base portion is flattened out to provide a support for maintaining the package article in an upright position. The plastic enclosure may be used with or without a display card.
