ABSTRACT:
A pour spout construction suitable for large collapsible reusable shipping containers employed for transporting particulate materials. The construction includes a spout member which folds against a side wall of the container rather than projects into the interior thereof, so as to afford no interference to the collapsing of the container when not in use, and no frictional resistance to opening the spout caused by the engagement of particulate material under pressure.
