Beschreibung
Zusammenfassung:	It is disclosed a rigid thin-metal food or foodstuff container and process for obtaining said container comprising a frangible surface with a scoring line for tearing open the container, wherein the scoring line is obtained by laser and/or mechanical weakening process without substantially applying heat-treatment strengthening to the remaining material of the frangible surface below the scoring line. L'invention concerne un contenant métallique mince rigide pour aliments ou produits alimentaires et son procédé d'obtention, ledit contenant comprenant une surface frangible présentant une ligne d'incision pouvant être déchirée pour ouvrir le contenant, la ligne d'incision étant obtenue par un procédé laser et/ou mécanique d'affaiblissement sans application importante d'un renforcement par traitement thermique au matériau restant de la surface frangible sous la ligne d'incision.
