Abstract: The invention relates to an end wall of a metal container having a score therein. The end wall is made of a composite metal sheet made of two or more metal layers, one of the layers being made of an aluminum alloy of high strength (e.g. a high magnesium alloy such as AA5182, AA5042 or AA5082, optionally with increased Mg), and another of the layers being made of an aluminum alloy having a good resistance to stress corrosion cracking (e.g. aluminum alloys AA3004, AA3104, AA5006 or AA5005), wherein at least the bottom of the score is formed by a surface of the alloy of good resistance to stress corrosion cracking.

Abstract: Exemplary embodiments of the invention relate to a container blank of defined shape, a method of feeding the blanks, and apparatus for feeding the blanks. The blanks are shaped or contoured in such a way that mutual adhesion between the blanks of a nested stack of such blanks can be broken, thus facilitating the delivery of individual blanks from the stack. The shaping of the blanks is effective to cause the blanks to separate from each other or to tilt mutually by a small distance when one blank is moved at approximately right angles to the stack. This allows ingress of air between the blanks that eliminates the mutual adhesion.
