A one piece pouring spout is inserted within a preformed can opening and fully seated for sealing against leakage and pilfering. In use, the spout is raised, to extended pouring position and rigidly retained within the can opening. The elongated tubular spout is integrally molded of synthetic plastic having its upper end closed off with a removeable sealing diaphragm and surrounded with a finger gripping ring. Upper and lower sealing surfaces are formed on the spout exterior to tightly engage the can opening in fully seated respective raised and lowered positions.
