Abstract: A composite can having improved “green” strength is made by pattern printing adhesive onto the exterior label or cover such that the adhesive covers less than 100 percent of the surface of the label. The total amount of adhesive applied between the label and the paperboard body wall is thereby reduced, so that less moisture is added on to the paperboard relative to conventional can-making processes in which adhesive is flooded onto the entire surface of the label. A preferred embodiment of the invention comprises an easy-open can, such as a dough can, having the adhesive applied with relatively denser coverage on the portion of the label that overlies the spiral butt joint that is formed between edges of the spirally wound paperboard body ply, and with relatively less dense coverage on other portions of the label.

Abstract: A tubular composite container includes a paperboard body ply wrapped into a tubular shape, and a polymer film liner ply wrapped into a tubular shape and adhered to the inner surface of the body ply. The liner strip includes a heat seal layer facing the body ply that is formed of a heat-sealable material, and the inner surface of the liner ply that contacts the mandrel is formed of a hard polymer material whose melting temperature is substantially higher than the sealing temperature at which the heat-sealable material softens and seals to itself. One edge portion of the liner ply is folded inward toward the mandrel, the liner ply is wrapped onto the mandrel such that the folded edge portion overlaps an opposite edge portion of the liner ply, and the heat seal layer on the folded edge portion is heat sealed to the opposite edge portion.

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.

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.

Abstract: An easy-open container has a spirally-wound bodywall layer, interior barrier liner layer and outer label layer forming an easy-open seam extending spirally between the ends of the container and which is provided with an improved reinforcing and tear strip extending along the easy-open spiral seam. This reinforcing and tear strip is formed by overlapped edge portions of the label layer extending through and out of the spiral seam of the container and being folded-over onto the outside of the bodywall layer and under the label layer. Low strength bonding is provided between the overlapped label layer edge portions and high strength bonding is positioned between the superimposed label layer and folded-over a liner layer edge portion and between the superimposed label layer and bodywall layer for allowing easy starting and stripping of the reinforcing and tear strip along the spiral easy-open seam without the necessity of removing the entire label layer.
