Improvements in the fastening and closing means in the lids for containers, characterized in that in a container and in its lid there is a emptying device for the extraction of air from the interior, remaining once emptied, hermetically closed when adjusting the lid flange with that of the container itself, carrying between them a rubber gasket provided with a tongue, from which it is pulled slightly to achieve the misalignment of the ring to the periphery of the container, and therefore entering the air and then opening.
