Abstract

The invention provides spirally wound easy-open containers which comprise a spirally wound body wall having overlapped edges and which have capabilities and benefits associated with conventional butt jointed containers. The overlapped edges of the body wall define an easy-open seam extending helically between the ends of the container. A temporary adhesive between the overlapped edges of the body wall releasably adheres the overlapped edges of the body wall together and allows for opening of the container along the helical, easy-open seam. The easy-open containers provided according to the invention can be readily manufactured with only slight modifications to the conventional manufacturing process. Nevertheless, the easy-open containers of the invention can provide for material savings in container label construction and can allow for vacuum packaging of food products such as dough.
