ABSTRACT:
A retractable turnspout closure for a flexible container comprises a plug mounted across the neck of the container, the plug having an offset opening and a valve member mounted over the opening and having the turnspout's turret mounted thereon. A cap mounted over the bottle's neck comprises an eccentrically oriented boss which abuts the plug base and causes the turnspout to extend or retract through a cap opening as the cap is rotated. When the turnspout is completely retracted a double seal exists comprising the cap wall and a shield extending upward from the plug base.
