STOPPER FOR A CONTAINER HOLE

摘要

The stopper has a first foil (12) closing the hole (11) of container (10). Metal foil (20) is provided, in most cases aluminium one, for induction sealing of the first foil (12) along the edge of hole (11), as well as removable or screwing body of the stopper (30). A controlled separating adhesive layer (15) between the first foil (12) and the metal foil (20) allows that after the removal of the body of the stopper (20) the metal (20) might be separated from the first (12) foil. There is elastic cloth (28) between the body of the stopper (30) and the metal foil (20) Between the metal foil (20) and the elastic cloth (28) there is a separation layer (25) liqefying at induction temperatures and an absorption layer (27). The latter, during the induction process, absorbs the liquefied substance of the separation layer (25).
