Abstract
A paper-based blister package comprising a flat card and a tray is provided. The tray comprises a bottom wall, two opposing side walls, two opposing end walls, two opposing side flanges, and two opposing end flanges. The bottom wall has a perimeter defined by two side fold lines and two end fold lines. Each side flange has at least one locking end that meets a side wall and a side flange fold line at a junction. The side flange and the side wall are contoured to define a side flange shoulder adjacent the junction. At least one end flange forms an outward projecting lip configured to engage the junction to maintain proper positioning of the side flange, the end flange, the side wall and the end wall.
