Abstract: A system for reconfiguring generally cylindrical, open-top containers (10) that are formed from metal utilizing a press (200) to force bottom portions (20, 12) of said containers (10) into a die (240) to carry out drawing operations that alter bottom (20) and side wall portions (12) of the containers (10) to elongate the containers (10) and to provide the containers (10) with tapered, fluted side portions (142) that enable the containers (10) to be nested for empty shipment and storage in a minimum of space. Each container (10) includes a pair of formations (130, 132) located atop the fluted sidewall portions (142) and a downward extending ring-like formation (134) located between the container's fluted side wall (142) and a raised bottom wall portion (128).
