Abstract
An easy-open container has a spirally-wound paperboard bodywall layer, interior barrier liner layer and outer label layer forming as easy-open seam extending spirally between the ends of the container. Easy-opening of the container is enhanced by the provision of pull tabs formed by superimposed and bonded longitudinal edge portions of the bodywall layer and label layer and an easy-open panel formed by diverging lines of score cuts formed in the bodywall layer to initiate and aid in easy-opening of the container along the spiral seam.
