Abstract

Abstract Easy opening configurations for forming in a container panel a dispensing opening. Each easy opening configuration is generally defined by one cut line and one or more score lines. A pull tape overlies the easy opening configuration and has a terminal end permanently bonded to the container panel. The pull tape also has a permanent bond with a removable panel portion defined by the cut and score lines as well as a peelable bond with the container panel surrounding the removable panel portion. If desired, apertures may be formed at the ends of the cut line to prevent initiation of rupture along the score lines. Also, if desired, force reducing openings may be formed in the removable panel portions.
