Claim:
1. A closure having a manually operable plastic spout attached thereto and extendable along an extension axis comprising: a molded plastic closure having a deck with an inwardly flanged cylindrical opening formed therein; an extendable plastic spout molded into a stable collapsed condition and comprising an integrally continuous plurality of annular wall sections of substantially equal thickness, rigidity and axial length, but of progressively smaller diameter interconnected by hinges of thinner, more flexible construction than said wall sections; said wall sections in the collapsed condition, laying concentrically within one another within said flanged opening wherein, when said spout is fully collapsed, the top edges of the collapsed sections lie substantially in a common plane perpendicular to the extension axis; a neck section integral with said plurality of annular wall sections and within the innermost of said wall sections and opening inwardly toward said flanged opening but being more rigid than said plurality of wall sections, said neck section having external threads formed thereon; said sections being extendible in sequence by over-center action but having a memory quality to return to the collapsed condition; a cap having a cylindrical neck portion and a larger diameter planar top portion, said neck portion having threads mating with the external threads of the innermost spout section to close the spout, the planar top portion lying substantially immediately above said common plane when the spout is in the collapsed condition; and an annular pull ring formed integrally with the top portion of the cap and in circumferentially surrounding relationship therewith; said pull ring being radially separated from said cap planar top portion by two circular slots but integrally joined with top portion by two radially extending tab portions such that the pull ring may be lifted out of the plane of the top portion and used as a grip to pull said spout to an extended pull condition; said cap top portion and said pull ring together being of sufficient diameter to substantially fill the cylindrical flanged opening in said closure deck and create a substantially flush deck structure; and said spout being permanently attached to said closure by insert molding.
