  • a case 2 comprising one or two closing tabs 3 can be closed by this way.
  • Such a system firstly guarantees effective retention of the closing tab 3 in the closed position as well as the inviolability of the case 2.
  • An opening force leads to a tear in one or other of the pre-cuts , or even of all.
  • the lugs 26, 26 'thus make it possible to hook the tab helping maintaining the closing tab 3 in the closed position and increasing the resistance to opening the closing tab 3.
