摘要 |
A pull-tab can closure of a thin metal foil membrane less than 0.15 mm. thick is provided with a peripheral scoreline for easy opening. The provision of a peripheral scoreline in a thin metal foil membrane is made possible by providing a flexible portion of the membrane parallel to and inside the radius of the scoreline. The flexible portion may be in the form of an inclined area relative to the scoreline or in the form of one or more concentric groove-like convex areas inside the radius of the scoreline. A method of making the closure and stamping means having a beveled score-forming edge are also disclosed. |
