    摘要: A barrier spout having a base flange and an upstand portion. The base flange has a top surface, a bottom surface and an outer surface. The upstand portion has a proximal end extending from the base flange terminating at a distal end. An upper opening is defined at the distal end, and a lower opening is defined at the proximal end. The base flange and the upstand portion each comprise a three layer co-molded configuration including an outer layer, an inner layer and a central layer. The central layer has an oxygen transmission rate that is less than an oxygen transmission rate of either of the outer layer and the inner layer.
