Abstract: A container, such as a beverage or food can is provided, which includes a first sidewall, a second sidewall and a bottom portion extending between the first and second sidewalls. The material of the bottom portion is stretched relative to the first sidewall and the second sidewall to form a thinned preselected profile, such as a dome. The material of the container at or about the dome has a substantially uniform thickness. The container is formed from a blank of material, which has a base gauge prior to being formed. After being formed, the blank of material of the container at or about the dome has a thickness less than the base gauge. Tooling having a clamp bead, or a progressive clamp bead, for selectively forming a blank of material into a container, as well as an associated method are also disclosed.
