Abstract (en)
[origin: EP0408268A2] A container closure has a diaphragm (3) supported by a ring (2). The diaphragm (3) has a pull tab (4) for peeling the diaphragm (3) from the supporting ring (2). The supporting ring (2) has a peripheral formation for securing the ring to a container body and extending radially inwardly therefrom an annular ledge having inner and outer parts (8), (9), axially spaced by a step portion (10). The inner part (9) extends into an annular curl (11) and then back on itself to overlie the inner annular part (9). In this way, the cut edge (112) of the annular blank from which the ring is formed is protected from the atmosphere and from the contents of the can. The invention provides a method and apparatus for manufacturing such a closure.
