A valve type spout assembly for use as an outlet on a fluid container, said spout assembly including a flexible spout and having: (a) an inlet neck section; (b) an outlet end section having a spout opening and external surface tapering inwardly in a direction extending toward the spout opening; (c) a separate tubular coupling member adapted to be removably secured at one end to the end section of the spout and at its other end to an external conduit; the opening through said coupling member adjacent the one end being tapered inwardly in cross-section in a direction measured away from the one end and having an internally ribbed section integrally formed at said one end with the ribs extending circumferentially around the opening through the coupling member; (d) a complementary shaped externally circumferentially ribbed section integrally formed on the end section of the spout for mating with the ribbed section of the coupling member to provide a fluid tight connection therebetween; (e) the one end of the coupling member being rigid in construction relative to said spout; (f) the opening through the coupling member being smooth and tapering inwardly in cross-section adjacent its other end as measured in a direction extending from the other end toward the one end thereof; and (g) said coupling member being flexible in construction along said last mentioned tapered cross-section to tightly frictionally engage the inserted end of the external conduit in sealing relationship.
