Tab seal for sealing a vessel to be closed by plug or cap and related manufacturing method

摘要

The joint has a support (11) connected to a cap (12) using temporary adhesive, where the cap is provided with a tab (13) whose surface is folded on a face of the cap in contact with a corresponding face of the support. The cap is formed of a complex part (14). The temporary adhesive is applied to the surface of the cap when the tab is folded. The complex part presents a notch. A fold is formed by the tab when the tab is folded, where the length of the fold is lower than that of the notch. The tab comprises a lower reinforcement film (19) made of polyethylene terephthalate. An independent claim is also included for a method for manufacturing a heat-sealable joint.
