Abstract
A valve bag adapted to have a filler nozzle inserted therein for filling the bag with bulk material is provided in its top portion with a filler valve which includes a tube of relatively stiff material extending inwardly from an opening in a wall of the bag. Secured to the inner end of the tube is a valve member in the form of a tube of limp, extremely flexible foil which projects inwardly beyond the end of the tube. The foil tube is normally collapsed to form a closure, but is expanded by insertion of a filler nozzle therethrough.
