摘要 |
<p>Disclosed is an opening device for a foil closure can be fitted to a container body. The device comprises a spout (4) with a removable disc (10) attached to a pull-ring (12). The disc (10) is secured to the spout (4) by means of a frangible region (30). A foil (8) is sealed to a raised land (34) on a base of the disc (10). The pull ring is mounted to the disc (10) by means of legs so that it applies a force on a peninsula (50) of the disc, thereby reducing the length of the arc over which an initial pulling force is dissipated when the initial tear is being initiated reducing the force required to tear the foil (8) by up to 40%.</p> |
