<p>An opening feature for a flexible laminate membrane having a metal foil layer sandwiched between first and second structures is formed by a first score line through a thickness of the first structure but not breaching the metal foil layer, and a second score line through a thickness of the second structure but not breaching the metal foil layer, the first and second score lines together encompassing a removable panel portion of the flexible membrane. A press-and-pull tab constituting part of the removable panel portion is arranged to be pressed downward to cause the metal foil layer to break in the region of the tab, and then to be grasped and pulled upward to cause the metal foil layer to break all around a periphery of the removable panel portion to enable the removable panel portion to be completely removed from the flexible membrane.</p> |
