ABSTRACT:
A nestable pouring spout assembly for dispensing liquid products from cans and pails. A molded plastic spout has in extended pouring position an enlarged flexible lower wall portion joined to a relatively rigid externally threaded upper wall portion closed off by an imperforate sealing diaphragm. A peripheral sealing channel is disposed about the base of the lower wall portion for securing to a container wall opening neck by means of an overlying metal crimping ring. The upper wall portion receives an internally threaded reclosing cap which is cooperatively engaged within the confines of the crimping ring when the spout is in stored position with the upper wall concentrically nested within the lower wall. Gripping bails integrally formed on the reclosing cap facilitate lifting the spout to raised pouring position by reversing the lower wall portion with respect to the sealing channel from a downwardly extending position to an upwardly extending position.
