ABSTRACT:
A carton and blank for forming the same are disclosed and includes a bottom panel, a top panel, side walls extending substantially perpendicularly away from the bottom panel toward the top panel with the side walls being connected to the bottom panel about a periphery thereof, and overlapping side walls extending substantially perpendicularly away from the top panel toward the bottom panel from predetermined peripheral edges of the top panel. An opening device is formed in the top panel for permitting access to an interior of the carton with the opening device including an opening force receiving mechanism in the form of a lifting tab is integrally formed in one of the overlapping side walls of the top panel for providing an initiation point for the opening device. Initial regions of weakness formed in the top panel extending from the lifting tab to respective peripheral edges of the top panel and continued regions of weakness are provided which extend from the initial regions of weakness substantially parallel to and including the respective peripheral edges of the top panel and extend toward a peripheral edge of the top panel which opposes the lifting tab wherein as previously mentioned, the continued regions of weakness include an inner partially cut score line of weakness and an outer perforated through cut line of weakness with the inner and outer lines of weakness extending substantialy parallel to one another such that a ply-separation occurs in the region between the respective lines of weakness when an opening force is applied to the lifting tab by the consumer. A device for facilitating the manipulation of the lifting tab is also disclosed.
