A method for closing and sealing containers, which essentially comprises a first step of punching a lamellar metallic ring so that a flange is formed at the central edge, to which a very thin circular metal sheet is applied in a second phase, by means of a scratch, by points or with rulinas. In a third phase, the assembly obtained is fixed to the upper edge of a circular container and finally in a fourth phase the circular cover covering the central sheet that acts as a seal is fitted.
