Adjacent terraces merge into one another with a height transition. To achieve low tear-force and/or other advantages, the intermediate terrace is inclined in a direction opposite to that of the outwardly adjoining transition at an angle .alpha. in the range 3 to 20 degrees to a plane perpendicular to the can axis.
