Title
(EN) CONTAINER AND CLOSURE WITH IN-TURNED SEAM
(FR) RECIPIENT ET BOITE A JONCTION PLIEE VERS L'INTERIEUR
Abstract
(EN)
A metal can (10, 50, 80, 110, 130) is closed by a specially prepared end closure (18, 64, 88, 120, 140). The open end (20) of the container is outwardly folded to define a supporting ledge and a seaming flange for the end closure. The seaming flange is to be folded or rolled inwardly for defining a seaming flange. The end closure is constructed with a frame member (26, 66, 90, 122, 142) defining a dispensing opening and having an end panel (28, 78, 92, 124, 144) which may be peelably removed to dispense the product from the container. Heat may be applied to the seam during the formation thereof or during a subsequent process step.
(FR)
La présente invention concerne une boîte de conserve (10, 50, 80, 110, 130) fermée au moyen d'une fermeture de bout d'un type particulier (18, 64, 88, 120, 140). Le bout ouvert (20) de la boîte est replié sur l'extérieur, définissant ainsi une corniche de support et une collerette de jonction destinées à recevoir la fermeture de bout. La collerette de jonction doit être tournée vers l'intérieur par pliage ou par formage à la roulette pour définir une collerette de jonction. Le fermeture de bout est réalisée au moyen d'un cerclage (26, 66, 90, 122, 142) définissant une ouverture de service et présentant un couvercle plan (28, 78, 92, 124, 144) qui peut s'ôter par arrachage pour servir le produit se trouvant dans la boîte. Il est possible d'appliquer un traitement thermique à la jonction pendant sa formation ou au cours de phases de traitement ultérieures.
