Metal container end with coined periphery edge and related methods

A metal container end comprising:

• a center section;
• a periphery section extending along a periphery of the center section;
• an outer surface;
• and
• an inner surface,
• wherein a distance from the outer surface to the inner surface is a thickness of the metal container end,
• wherein the periphery section comprises an edge extending between the outer surface and the inner surface,
• wherein the edge comprises a contacting portion and a non-contacting portion, and
• wherein the contacting portion of the edge extends from the outer surface towards the inner surface and at a non-zero angle relative to the non-contacting portion.

A method of forming a metal container end, the method comprising:

• blanking a material to form the metal container end such that the metal container end comprises a center section and a periphery section extending along a periphery of the center section;
• coining an edge of the periphery section and forming a contacting portion of the edge that extends at a non-zero angle relative to a non-contacting portion of the edge;
• and
• shaping the metal container end such that the periphery section comprises a curl between the center section and the edge.
