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.
Cette invention concerne un contenant facile à ouvrir dont le corps est en carton spiralé à doublure formant barrière et à revêtement extérieur porte-étiquette comportant entre les deux extrémités du contenant un joint spiralé facile à ouvrir grâce à une bande d'arrachage renforcée le long dudit joint spiralé. La bande d'arrachage renforcée est formée par les bords chevauchants de la doublure sortant du joint spiralé du contenant et repliés sur l'extérieur du contenant et sous le revêtement porte-étiquette. Une colle à faible résistance est prévue entre les bords superposés du revêtement porte-étiquette et une colle haute résistance entre le revêtement porte-étiquette et les bords repliés de la doublure et entre le revêtement porte-étiquette et la face extérieure du contenant spiralé pour permettre l'amorce facile de l'arrachage de la bande d'arrachage le long du joint spiralé sans nécessité d'enlever le revêtement porte-étiquette au complet.
