Blister pill package with safety backing

Image Number 4 for United States Patent #6516949.

A non-through score line is made in the exposed surface of the blister sheet of a blister package. The non-through score line extends from one edge of an individual blister unit to an opposite or adjacent edge, i.e., across the corner of the blister unit. When the blister unit is angulated or flexed back at the non-through score line, the blister sheet will fracture. The smaller portion of the fractured blister sheet, still bonded to a backing sheet, acts as a tab for peeling the backing sheet from the blister sheet exposing the blister contents. Camouflage lines on the blister sheet help hide the score line, thereby rendering the package highly child-resistant.
