Definitions

  • the invention relates to a container, specifically to a container comprising an easy open end.
  • Containers with easy open ends are e.g. used for CLUB cans. These containers, including the end, are typically made of sheet metal. Foodstuff, e.g. seafood, is commonly housed in these containers.
  • the containers and the corresponding ends are provided to a customer, i.e. food manufacturer, separately in large quantities.
  • the customer can fill the container with foodstuff, e.g. seafood, and close the opening of the container with the end (the lid), e.g. by a double seam.
  • Filled containers are presented at a point of sale in e.g. a supermarket for customers. Such containers are typically stacked in order to save precious room at store shelfs.
  • Known containers that comprise a bead for enhanced stability and/or a depression in the end close to a pull-tab for facilitating access to the pull-tab are not stackable with a sufficient stability of the stack.

Le panneau central (312a) définit un plan x-y et une direction z est perpendiculaire au plan x-y. La languette (340a) est fixée à l'extrémité (300a) et la languette (340a) s'étend dans une direction z positive. La ou les nervures de stabilisation (313a) sont formées dans l'extrémité (300a) et la nervure (313a) s'étend dans la direction z positive. Le corps de contenant (360a) comprend une surface inférieure (385a) opposée à l'extrémité (300a). Le contenant (350a) est conçu pour être empilé avec un second contenant (350b) comprenant une seconde extrémité (300b) avec un second panneau central (312b) de telle sorte qu'une partie de la surface inférieure (385a) du contenant (350a) entre en contact avec une partie de la seconde extrémité (300b) du second contenant (350b), et le panneau central (312a) du contenant (350a) est parallèle à ± 2,0° au second panneau central (312b) de la seconde extrémité (300b) du second contenant (350b), le contenant (350a) et le second contenant (350b) étant des contenants identiques (350a, 350b).
