METHOD OF MANUFACTURING A METAL CONTAINER LID

Abstract

Method for manufacturing a metal container lid with a reclosable opening, wherein the metal container lid is provided with a microgap (4) or a weakening line (4', 4") circumferentially around the opening, a sealing frame (5) of plastic material which is connected to the fixed surface of the lid (2) and surrounds the opening area, a closure unit (6) of plastic material which is connected to the upwardly rotating metal lid area (3) within the microgap (4) or weakening line (4', 4"), which can be applied to rotate via the rotation bearing (7) on the fixed surface of the lid (2) and is provided with a tearing member (8), which is located diametrically opposite the rotation bearing (7) and is connected so that it can rotate upwardly with the closure unit (6),wherein the sealing frame (5) and the closing unit (6) interact in a sealing manner, preferably by means of sealing and locking ribs (12, 13, 14) and corresponding receiving notches (15, 16, 17), and the metal area of ​​the lid (3) provided within the peripheral microgap (4) or the weakening line (4', 4") receives and is held within the area of ​​the opening of the lid (1), where the sealing frame (5) is continuous with the fixed surface of the lid (2) and the closing unit (6) is continuous with the upwardly rotating metal area of ​​the lid (3), in particular by using an adhesive, by means of a thermal method, where the adhesive is added and mixed into the corresponding plastic material, before the shaping into mold of the sealing frame (5) and / or the closing unit (5).,
