The principles of the present invention further provide both a shaped metal container and its preforms that exhibit a rounded grain structure characteristic created by an annealing process and a method for making a shaped metal container. The process of making said metal container results in a quicker process time and uses less metals (at least 10% metal weight savings), thus allowing for a decrease in the costs of making such shaped metal containers. A shaped metal container may include work hardened rolled sheet-metal defining a sidewall, an opening, and a base, where at least one section along the sidewall has grains with an average aspect ratio less than about 4 to 1.
A shaped metal container comprising a container middle section connected at one end to a container bottom section, and at the other end to a top section, at least part of the container top section, the container middle section and/or the container bottom section being shaped by necking and another part being shaped by outwardly shaping, such that at least one of the middle section diameter Dm, the bottom section diameter Db, and the top section diameter Dt is greater than, and at least one of the middle section diameter Dm, the bottom section diameter Db and the top section diameter Dt is smaller than the cylinder diameter Dc of a container preform from which the shaped metal container has been made;
A shaped metal container comprising work hardened rolled sheet-metal defining a sidewall, an opening, and a base, wherein at least one section along the sidewall includes grains with an average aspect ratio of less than about 4 to 1 and at least one other section along the sidewall includes grains with an average aspect ratio of greater than about 4 to 1.
A shaped metal container comprising a container middle section connected at one end to a container bottom section, and at the other end to a top section, wherein the container top section, container middle section and/or container bottom section includes a work hardened rolled sheet-metal including a rounded grain structure with an average aspect ratio of less than about 4 to 1 formed by annealing, and at least one other section includes a work hardened rolled sheet-metal including a rounded grain structure having grains with an average aspect ratio of greater than about 4 to 1.
