ABSTRACT:
An improved push/turn tap and drain spout fitment for a multi-wall fiberboard container with a plastic retainer for retaining bulk flowable materials including a polygonal flange mounted within a similarly shaped opening in the fiberboard. A valve tube extendable through a spout assembly. The valve tube includes prongs for engaging a bung which is threadably connected to the spout assembly to seal an opening in the plastic retainer. The valve tube, though sealingly coupled to the spout assembly, can be moveably manipulated from the outside of the container to cause the bung to become disengaged from the spout assembly.
