New closure for all types of containers, essentially characterized by that to facilitate the space necessary for the expansion of the materials contained in the container during its heating and its return to the primitive volume after they have been cooled, without taking place inside that nor in the first and second cases appreciable pressures, the metal lid is given a symmetrical and regular undulation in concentric circles reversed high relief, which increasing the surface of the cover facilitate its movements in and out with very little effort.
