ABSTRACT:
An improved discharge spout construction for a collapsible receptacle where the entire assembly is constructed with one pass of a double needle sewing machine, thus enabling the construction to be accomplished in a very economical and efficient manner. The spout, the panel which covers the opening in the bottom of the receptacle and the folded triangular flaps which form the drawstring passageways are all sewed together with two spaced sew lines to create a buffer zone between product in the receptacle and the cuts forming the triangular flaps so that if the cuts tear past the first sew line, the second sew line separates the product from the tear.
