Abstract

The valve system according to the invention consists of three elements E1, E2 and E3, the first of which has: at the bottom end a rim C which is welded to the inside wall Pi of the bag Sa; a raised portion PR defined by shoulders SP which provide support for the second element E2 consisting of a small elastomer disc; and a top end for engagement with the third element E3 in the manner of an inverted cup. The raised shoulders of E1 are closed at the top by an internal central membrane section so as to create a zone into which the liquid of the bag penetrates, said liquid being thus removed from said zone by the run-off device introduced therein without any danger of perforating the wall of the bag.
