Abstract:
A method for manufacturing a press-on lid intended to be clipped onto a tubular container, the container equipped with an outwardly rolled edge at its top end, the lid comprising a strip and a pressed disk, characterized by the following steps:cutting the strip from a rigid and fibrous material having on one of its faces an adhesive, the cut being made parallel to the fibers of the material, forming a ring on a form of a size equal to the internal dimensions of the lid, the length of the strip allowing the ends to be superposed around the form so that they can be sealed together, cutting a disk from a rigid material in a shape that corresponds to the lid prior to pressing, introducing the ring and disk into a two-stage tool, the disk being introduced into an upper part and the ring into a lower part, introducing a heated punch into the ring and pressing and sealing the disk onto the ring by means of said punch and of a die of said tool, and forming a nesting profile at the end of the travel of the punch.
