Abstract
Process for manufacturing a metal can with a threaded neck on which a removable head can be fitted, includes the steps of forming a can with a closed bottom end, a cylindrical wall and an open top end, forming a neck at the open top end, obtaining a ring with a spindle hole of known diameter and a threaded external surface, sleeve fitting the ring by driving the spindle hole over the neck, and plastically expanding the neck by an amount sufficient that its outer diameter exceeds the diameter of the spindle hole when unstressed.
