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.

An improved discharge spout in the bottom panel of a collapsible receptacle for flowable products comprising: a substantially cylindrical spout of flexible material; at least three triangular flaps formed in the bottom panel with intersecting cuts of predetermined length, the outer ends of said cuts forming potential tear locations; an opening formed in the bottom panel when the triangular flaps are folded into the interior of the receptacle; a substantially circularly shaped flap for covering the opening; means for securing one end of each of the folded flaps to the inner side of the receptacle bottom panel beyond the outer ends of said cuts of predetermined length to form drawstring passageways, said securing means creating a tear resistant buffer zone of predetermined width between a potential tear location and the product to minimize loss of product if said intersecting cuts tend to tear; said securing means simultaneously securing a portion of the circularly shaped cover flap on only one side of the opening and one end of the cylindrical spout to the bottom panel entirely surrounding the opening on the interior of the receptacle such that the cover flap covers the opening with the spout on the interior of the receptacle; and a drawstring in the drawstring passageways formed by the secured, folded flaps such that when the drawstring is untied, the cover flap and pouring spout can be withdrawn through the opening and when the receptacle is closed, the spout is inside the receptacle, the opening is closed by the cover panel from the inside of the receptacle and the drawstring is drawn and tied to keep the opening securely closed.
