This relates to a conventional type metal container end having a modified end hook configuration for the purpose of eliminating undesired wrinkles within a conventional type of double seam between a metal container end and a container body. Most particularly, a customary straight section between an end curl and a cut edge of the metal container end is eliminated so that the end curl terminates at the cut edge. Additionally, the end curl is reinforced so as to stiffen the end curl by providing a reinforcement generally in the area of the normal juncture between a seaming panel and the end curl. In a preferred embodiment the reinforcement is arched primarily upwardly.
