Metal Can Body

Abstract

Can body including an essentially round cylindrical circumferential metal wall, wherein the wall has purposively selected thick and thin walled annular sections and the wall is at least partly provided beads.

1 . Can body comprising an essentially round cylindrical circumferential metal wall, wherein the wall comprises purposively selected thick and thin walled annular sections and the wall is at least partly provided with beads. 
   
   
       2 . Can body according to  claim 1 , wherein the can wall is wall ironed. 
   
   
       3 . Can body according to  claim 1 , wherein the metal wall is provided with at least an annular portion of a relatively small wall thickness provided with relatively shallow beads and an annular portion of a relatively large wall thickness provided with relatively deep beads so as to optimise the ratio mechanical performance/metal consumption. 
   
   
       4 . Can body according to  claim 3 , wherein the annular portion of relatively large wall thickness is positioned in a middle region of the wall. 
   
   
       5 . Can body according to  claim 3 , wherein there is an annular portion of relatively small wall thickness on either side of the annular portion of relatively large wall thickness.
