The cover is provided with a prolongation constituting a tab (4) whose entire surface is folded on a face of the cover in contact with a corresponding face of the support. A sheet (6) i.e. aluminum sheet, of the cover is constituted by an upper reinforcement film (7) and a lower heat sealing film (8) applied on a sealing surface of a container, where the sheet is made of conducting material. The tab is realized in the prolongation of the upper reinforcement film. The temporary adhesive is presented in form of an extruded or co-extruded film. An independent claim is also included for a method for manufacturing a heat-sealable seal for closing a container.
