Improvements in the manufacture of closing and sealing devices for containers, characterized by comprising the arrangement in the lower area of the laminar piece constituting the closing and sealing device, a ring separated from the rest through multiple lines of weakening that is they extend peripherally according to a circle in the external part of the laminar piece, constituting zones of thinning of the material by previous compression, whereby their weakening is achieved and said zones being separated by connecting bridges between the upper zone of the laminar piece and the ring, in which it also has a weakening zone disposed according to a generatrix and extending to the greater part of the length thereof, allowing the unscrewing operation of the sheet piece, adapted to the container neck, The lower ring is detached in a single piece, the breakage of which must be carried out subsequently in its weakened area.
