Claim 1

A retractable turnspout closure for a container comprising: a plug base for mounting across a neck of said container, said plug base having an opening offset from its center; a valve seat mounted on said plug base over said plug base opening; a retractable and rotatable turnspout having a turret which mounts on said valve seat; a rotatable cap having an opening in a side wall thereof, a plurality of inwardly projecting members from said side wall, and a boss mounted on and projecting downward from a top of the cap, said boss including means to guidedly engage said retractable and rotatable turnspout and rotate it eccentrically in response to a turning of said cap to a first position wherein said turnspout extends through said opening and a passageway is thus formed from the container's interior through said valve member and an opening in said turnspout leading to the atmosphere outside the container, and further comprising a shield member mounted on said plug base to abut an end of said turnspout and thus to block said passageway when said turnspout is rotated into a second retracted position, said shield member having an outer surface in sliding contact with the inner surface of the cap whereby, said shield with said cap side wall substantially forms a double seal for said turnspout when said turnpoint is in said second position.
