  • Patent number: 5924627
    Abstract: A packaging blank is scored with several substantially parallel laterally spaced apart score lines adjacent the intended location of a rounded edge on the container produced from the blank. The score lines are formed on the inside surface of the blank which places the score lines inside the container formed from the blank. When the blank is bent into shape at the rounded edges, a portion of the total deflection is absorbed by each score line whereby the resulting container edge is a gradual curve rather than a single sharp crease. Placing the score lines on the inside of the formed container results in opposing faces of the container being planar and parallel to one another.
