Abstract

See full text

A clamshell type carton is provided with a cut along the hinge score line connecting the upper cover and lower tray portions. A second cut is placed in the back panel of the carton, above or below the hinge score line cut, wherein the second cut is a continuous curve having a first end point located in the back panel and a second end point intersecting the cut along the hinge score line. The second cut is utilized to facilitate the easy opening and closing of the carton without buckling occurring in the back panel in the region of the hinge score line.
