摘要： A one-piece can body having a reinforced pressure-resistant can bottom is formed by first forming a generally cup-shaped blank defined by a generally cylindrical body, a radius portion and an end, exerting first forces against the cup-shaped blank in a first direction to form the end into a concavely outwardly opening end defined by a central end panel, a frusto-conical wall and an annular inwardly opening channel merging with the cylindrical body, and exerting second forces against the annular channel in a second direction opposite the first direction while gripping the central end panel to reform either or both the frusto-conical wall and a part of the annular channel to selectively form one or both of an inwardly projecting outwardly opening annular bead and an outwardly projecting inwardly opening annular bead defining respective reinforcing and stacking beads, and the first and second directions defining a single reciprocal opposing path of force exertion by the first and second forces.
