Packaging system

Abstract

The invention relates to a packaging container for pourable liquids, powders and granules, in particular pourable food products, wherein the packaging container comprises an inner flexible bag having an outlet opening, and further comprises an outlet part and an outer cover adhesively bonded to the inner bag in a punctiform manner that be disposed of separately therefrom. A carrying handle makes it possible for a variety of packaging containers to be transported easily. The outer cover of the packaging container may comprise two swing-open hard shells. A further packaging container according to the invention comprises a foldable outer cover and, when the latter is folded, the inner flexible bag can be fastened to the cover by means of the outlet part and, when the cover is unfolded, the inner flexible bag can be separated therefrom and the two can be introduced into different recycling systems.
