A unitary V-lipped pour spout for a wall of a container, said spout formed from a plastic sheet and comprising:

• a peripheral mounting frame defining a generally triangular shaped opening, said frame adapted to be mounted around the edge of an opening in the container wall with the apex of said triangular shaped opening pointing downwardly;
• a spout element having a hinged attachment to said mounting frame, said spout element including a generally triangular first face portion shaped to correspond generally to said triangular shaped opening, a connecting portion joining said first face portion to said mounting frame and including a first fold line providing said hinged attachment, and a generally triangular second face portion joined to said first face portion along a common edge, said common edge defining a second fold line;
• said spout element adapted to be initially folded on said first fold line to place said first face portion over said triangular shaped opening to define a closed spout position;
• and,
• said first and second face portions adapted to be pulled partially through said triangular shaped opening to cause said first and second face portions to flex relative to one another on said second fold line to form said spout and define an open spout position.
