The spout assembly for a flexible bag of claim 4, wherein the upper portion of the first threadform and the second threadform each define an upper threadform thread diameter and wherein the lower portion of the first threadform and the lower portion of the second threadform define a lower threadform thread diameter, wherein the upper threadform thread diameter is smaller than the lower threadform thread diameter. 6. The spout assembly for a flexible bag of claim 1 wherein the spout further includes an upper body flange spaced apart from the proximal end and the distal end extending about the body of the spout, with the first threadform and the second threadform extending along the outer surface of the body between the distal end and the upper body flange. 7. The spout assembly for a flexible bag of claim 6 wherein the first threadform and the second threadform terminate at the upper body flange. 8. The spout assembly for a flexible bag of claim 7 wherein the upper body flange includes an outer surface, spaced apart from the body of the spout, the first threadform and the second threadform extending over at least a portion of the upper body flange. 9. The spout assembly for a flexible bag of claim 6 wherein the spout further comprises a lower body flange extending about the body of the spout, the lower body flange being spaced apart from the base flange and the upper body flange. 10. The spout assembly for a flexible bag of claim 9 wherein the base flange, the lower body flange and the upper body flange are substantially parallel to each other. 11. The spout assembly for a flexible bag of claim 9 wherein the spout further comprises an upper annular rim flange having an inner seat defining a diameter that is larger than a diameter of the body of the spout, an upstand wall extending away from the proximal end of the spout, and an outwardly extending outer portion at a distal end thereof. 12. The spout assembly for a flexible bag of claim 11 further comprising an insert member slidably positionable within the spout. 13. The spout assembly for a flexible bag of claim 12 wherein the insert member includes a cylindrical body having an outer surface and an inner surface, the cylindrical body has an inner connector actuating assembly which includes a base web extending across the inner surface of the cylindrical body to cooperatively define a cavity, a connector engagement post extending from the base web toward a top end of the insert member, and spaced apart from the inner surface of the cylindrical body and a connector engagement rib extending between the connector engagement post and the inner surface of the cylindrical body and having an upper surface that is spaced apart from the base web, and at least one transverse slot extending from the cavity through the cylindrical body near a bottom end of the cylindrical body. 14.
