CA 2558651

An easy open end for a container includes an end panel (60) having a score defined therein that defines a removable end panel portion. The score is preferably notched to define a bottom edge having a continuous V-shaped recess. A first double fold (134) is defined adjacent to and positioned radially inward from the score (81) that defines beneath the score a first outwardly projecting extending cut protection bead (138). A second double fold (136) is defined adjacent to and positioned radially outward from the score (81) that defines beneath the score a second inwardly projecting cut protection bead (140). The end panel is elastically deformed in an area near the score so as to define a concave depression (144) about the score, which provides enhanced cut protection.

L'invention porte sur une ouverture rapide de couvercle de récipient comportant un panneau d'extrémité (60) présentant une rainure en délimitant une partie ouvrable laquelle est de préférence entaillée pour définir un rebord inférieur présentant un évidement continu en V. Un premier double pli (134) voisin de la rainure (81) et placé radialement à l'intérieur de la rainure forme sous elle un premier bourrelet (138) de protection contre les coupures, saillant vers l'extérieur. Un deuxième double pli (136) voisin de la rainure (81) et placé radialement à l'extérieur de la rainure forme sous elle un deuxième bourrelet (140) de protection contre les coupures, saillant vers l'intérieur. Le panneau d'extrémité, qui peut se déformer élastiquement dans une zone voisine de la rainure, forme autour une dépression concave (144) constituant une protection renforcée contre les coupures.
