ABSTRACT:
An easy-open container has a spirally-wound paperboard bodywall layer, interior barrier liner layer and outer label layer forming an easy-open seam extending spirally between the ends of the container. A feature is provided for directionally-orienting tearing of the label layer to remove either the entire label layer or just that portion of the label layer which is in bridging relationship to the easy-open spiral seam to allow opening of the container along the spiral seam. The directionally-orienting tear feature is preferably provided by a reinforcing and tear strip having directionally-orienting tear incorporated therein and which is positioned under the outer longitudinal edge portion of the label layer and over the easy-open spiral seam along with desired positioning of low strength and high strength bonding between the label layer, reinforcing and tear strip and bodywall layer to ensure tearing of the label layer in the proper direction and removal of a desired portion of the label layer when the container is opened. The directionally-oriented tear feature may also include a directionally-orienting tear incorporated in the label layer itself to orient tear in the desired direction.
