Abstract
Valve device for flexible containers, characterized in that it is constituted by a flexible tubular form, flattened and closed by one end, which is permanently deformed in order to determine a fold, segregating said tubing, for opening the container in which it is incorporated, according to a line between the closed end of the tubing itself and its fold, in which circumstance the fold is opened by the compression exerted on the packaged liquid and it closes when said pressure ceases, respectively determining the de-occlusion and the automatic filling of the container.
