Abstract
A die system (10) for cutting a piece of sheet stock (11) to create a blank and forming the blank to create a container includes first and second mating die halves (56, 96) and a cutting punch (68). The first and second mating die halves (56, 96) are configured to move together to form the container from the blank. The cutting punch (68) extends about the first die half (56) and is movable therewith. The cutting punch (68) is configured to cut the piece of sheet stock (11) to create the blank. Movement of the die halves (56, 96) together causes the cutting punch (68) to cut the blank from the piece of sheet stock (11) and further movement of the die halves (56, 96) together causes the first and second die halves (56, 96) to form the container from the blank.
