Abstract:
Method for manufacturing an overcap, comprising the steps of:a) forming a blank of said overcap from a metal layer and shaping said blank into a head portion and a skirt portion comprising an opening area constructed and arranged to be broken during removal of the overcap;b) placing a sleeve made of a plastic film on a mandrel;c) placing said blank on said sleeve on the mandrel;d) using a heated die to exert pressure and transfer heat from the die to the blank and to the sleeve, at a temperature and for a time sufficient to cause adherence of the sleeve and blank without melting of the sleeve at a sleeve-mandrel interface, said sleeve being adhered to said shaped blank over an area limited to said opening area; ande) optionally further shaping the blank by forming means for facilitating an initial opening.
