Abstract
A closure for sacks, bags and like containers which have non-rigid walls and which are to be pressurized. The closure includes a filling nozzle having a tubular stub and a flange. The flange has a tubular cylindrical portion and a plate-shaped portion. The plate-shaped portion of the flange is attached to the container. The filling nozzle may be caused to sealingly engage the flange by use of a snap connection, whereby the closure is either completely open or closed. The snap connection either retains the filling nozzle in firm and tight engagement with the flange, or releases the filling nozzle in relation to the flange.
