The "INTRODUCED DESIGN FOR METAL CONTAINER LID-SEALS FOR LIQUIDS" is made up of a securing system obtained by means of a beading process of the upper rim of the metal container (1), preferably manufactured from tinplate; characterized by its plastic membrane (2) assembly, metal ring (3) stamped to conform to a flat inner section (4) with a central circular opening (5), and a drawn inner edge bent toward the inside (6) with a ridge to conform to a recessed bed (7) that is enclosed by a peripheral edge bent downward and slightly inward (8) allowing beading with the membrane (2); the peripheral border (9) that fits into the bed (7) and beaded to the container's edge (1); followed within by the ring- shaped recess (10) that the flat internal section (4) fits into, with the drawn and bent inner edge toward the inside (6) of the metal ring (3); this in turn being followed by the inner stiffened perimetral ring (11) and the lower tapered triangular breaking band (12) that upon pulling the built-in pulltab (13); partially breaks the tilting triangular lid (14) at the thicker tapered band (15) at its lock (16).
