Abstract
A laminated or multiple-ply structure comprising an inner wall of a substantially rigid material and an outer wall of a thin generally pliant material, such as a glossy finished paper, adhesively fastened thereto by a suitable adhesive or glue. A plurality of artifact receiving pockets are formed in the thin outer wall of the container, with each pocket being formed through the intermediary of a suitable perforation configuration formed therein. Each perforation configuration includes slits penetrating through the outer wall material and defining a pocket by a plurality of discontinuous slits extending along the semicircular peripheral edge of the pocket. The laminating adhesive is interposed between the inner and outer walls to form the laminated structure with an adhesive repellent medium being provided intermediate the inner and outer walls in areas substantially coextensive with the areas of the pockets such that each pocket is expandable away from the inner wall to facilitate the insertion therein of a medallion or other suitable artifact. The teachings herein have particular applicability to a packaging arrangement for consumer products such as a laminated box for breakfast c…
