ABSTRACT:
A scoring tool for forming a scoreline having a predetermined depth in a composite container label layer is disclosed, including an annular scoring blade and a holder assembly supporting the blade for rotation about an axis. The holder assembly includes a blade holder member having an annular portion at one end upon which the blade is mounted, the outer diameter of the annular portion corresponding with the inner diameter of the scoring blade. The blade holder member also has at its other end a flange portion the outer diameter of which is less than that of the blade member. The holder includes an annular locking member for retaining the scoring blade in contiguous relation with the flange portion. The locking member is mounted concentrically about the holder member annular portion, the outer diameter of the locking member being less than that of the flange portion. When the scoring tool is rotated relative to, and is pressed against, the composite container label layer, the scoring blade penetrates the label layer to a depth equal to the distance between the outer radius of the blade and the outer radius of the blade holder member flange portion.
