Abstract:
A method of production for a 2-piece “Combo” style closure (1′), having a disk (10′) constrained within a peripheral ring (20′). The “combo” style closure (1′) is produced from a conventional one-piece closure shell (1) by cutting the sidewall (20) in the vicinity of the top plate (10) to produce the ring (20′) and disc (10′) respectively.
