The existing closures have a score part on their surface, mounted so as to be detached in case of pressure. The applied pressure causes the surface to sink in the content of the container, creating a risk of contamination of the content and subsequently the consumer, in case the surface had not been carefully cleared and carries noxious substances. The advantage of the closure to be created is that it has a protective membrane (figure7, number 5) made of aluminum sheet, whereas the already existent closures do not have this protection. This membrane is gathered to a direction resulting in its attachment on the perimeter of the closure, so that the consumption from mouth is inhibited. The use of the closure with hygiene membrane made of aluminum sheet that sinks in the content concerns the sealing with closure of beverages or beer metal containers.
