Abstract
A closure device for containers comprises a lid having a spout () with holes (), a valve body () attached to the lid () and operable on the spout (). The valve body () comprises a cup-shaped element () having a blind bottom wall () and a side wall () that emerges from the bottom wall () and delimits an upper opening, the side wall () of the cup-shaped element () being made of a resilient material, and at least partially contacting a first sleeve () of the lid (), which is in fluid communication with the spout (). The side wall () of the cup-shaped element () contacts the first sleeve () in a fluid-tight manner and moves away from the first sleeve () in response to a negative pressure introduced through the spout ().
