Abstract

Procédés et appareil de formation d'une structure de fermeture en tôle pratique (133) pour un corps de récipient (153) présentant une paroi latérale non cylindrique. Une nouvelle configuration d'outil de formation d'entaille (94) permet de placer une ligne d'entaille périphérique (102) définissant un panneau séparable pratique (112), à proximité de la paroi de fermeture (100), s'adaptant autour de la totalité de sa périphérie à l'extrémité ouverte de la paroi latérale dudit récipient. La séparation dudit panneau ne laisse aucune obstruction au retrait du récipient de conditionnement solide. Le panneau séparable (112) se compose d'un pli multicouches (127) en tôle, Lequel est logé contre la périphérie intérieure dudit panneau, de manière à protéger le métal résiduel tordu restant avec le panneau après séparation le long de ladite ligne d'entaille périphérique. Le fait de placer de manière présélectionnée un système d'ouverture intégré allongé (148) tel qu'on le trouve sur divers panneaux de parois terminales de configuration non circulaire, ainsi qu'une nouvelle forme d'élément de serrage (170) permet l'assemblage d'un support d'élément de serrage voulu destiné à une jointure de bordure extérieure, de ladite fermeture terminale en tôle à un corps de récipient.
