Spirally-wound easy-open container having a score cut opening panel

摘要

A spirally-wound paperboard bodywall layer in strip from defines a cylindrical container having opposed ends, having longitudinal edges lying adjacent each other to define an easy-pen spiral seam extending between the opposed ends. A flexible barrier liner layer is in strip form spirally-wound inside the bodywall layer in superimposed position with. A flexible label layer in strip form a spirally-wound outside the bodywall layer in superimposed position with and have longitudinal edge portions overlapped with each other adjacent and to one side of the easy-open spiral seam. The uppermost of the label layer over lapped edge portions being positioned in bridging relation to the easy open spiral seam. A high strength bonding member is positioned between the label and the bodywall layers. Tab cuts extend through the upper of the label layer edge portions and inwardly from an outer edge of past the spiral seam and through the bodywall layer longitudinal edge portion superimposed under to define an easy open pull tab includes both the upper of the label layer edge portions, and the inwardly underlying bodywall layer longitudinal edge portion. Score cuts extend through the bodywall layer, and extend in diverging lines from the pull tab to define an easy-open panel for the container which is adapted to tear when the pull tab is pulled to easy-open the container.
