Described is a plastic flat monolithic cap having thin walls with a thin membrane that is pressure broken. Said membrane is useful for attaching a tab having a central depression formed by a wall extension to the upper edge portion of an enlarged skirt and to a transversal wall, where said skirt and wall result from a flat base; the tab having a horseshoe-shaped central depression formed by a lower wall extension, is extended beyond the plane defined by the lower surface of the base in order to balance out the thickness of the container cardboard and to be attached to the seal film of the container.
