ABSTRACT Packing containers of the non-returnable type for the packaging of milk, etc, frequently have a fold-out pour- ing spout which is intended to facilitate the pouring out of the milk in a concentrated jet. However, the air which must enter the package via the pouring spout at the same time as the pouring out takes place causes the flow to stop periodically so that the pour- ing out occurs jerkily. This disadvantage is overcome in accordance with the invention in that the spout is designed to have an emptying duct as well as an air duct. The air duct extends into the packing container over such a length that air can pass un- hindered into the packing container without disturbing the flow of the contents through the pouring spout.
