Abstract
Abstract A double-faced blister pack and frame assembly for packaging and displaying an article of merchandise. The article is sandwiched between a pair of superposed, transparent plastic sheets whose central regions are molded to generally conform to the opposite faces of the article, the four superposed margins of the sheets each defining a flange. The frame is formed of a cardboard strip that is so die-cut and folded as to create a chain of four interhinged branches each having a triangular truss cross section whose base chord is the outer wall of the frame and whose central strut is constituted by parallel walls extending from the apex of the triangle to the base chord to form a narrow slot. Socketed in the slot of each branch is the corresponding flange of the pack whereby the pack is supported by the frame, and the opposite faces of the article which lie within the frame are both exposed to a prospective purchaser who is able to fully examine the article without having to break open the package to do so.
