ABSTRACT:
A packing container with an unfoldable pouring spout which has an inherent tendency to assume an unfolded position when the container has been opened is disclosed. The ability of the pouring spout to tend to assume the unfolded position is achieved by having certain folding lines of the container weaken the material of the container to an appreciably greater extend than certain other folding lines of the container. The relative difference in weakening of the material caused by the folding lines utilizes the elasticity of the packing material to urge the pouring spout to unfold.
