ABSTRACT:
To produce a container with a rounded edge, the container blank is scored with several substantially parallel, laterally spaced score lines adjacent the intended location of the rounded edge. When the blank is bent, a portion of the total deflection is absorbed by each score line so that the resulting container edge is a gradual curve rather than a single sharp crease. The ends of each scored region may be left unscored to further smooth the ends of the rounded container edge. Methods and apparatus for forming the above-described blank are disclosed.
