Abstract
Abstract A pouch which is formed to provide an inwardly folded bottom wall to which a discharge fitment is attached so that the weight of the fluidic material within the pouch causes the bottom wall to be extended when the pouch is disposed in a generally vertical configuration to provide a funnel by which all of the contents of the pouch may be discharged.
