A pouring spout adapted to be releasably secured to an oil container or the like comprising: (a) a tubular body member having an attachment end and a pouring end, the attachment end defining an annular lip extending outwardly from the body member and the pouring end having a cylindrically shaped outer surface portion; (b) connector member rotatably mounted on the attachment end of the tubular body member and extending over the lip thereof, the connector member defining threads adapted to engage complementary threads on the container; (c) a funnel shaped member rotatably mounted on the tubular body member adjacent the pouring end thereof, the funnel shaped member including a rear cylindrical section having a cylindrically shaped inner surface which surrounds the tubular body member adjacent the pouring end thereof and a front cylindrical section of smaller diameter than the pouring end of the tubular body member and a tapered section joining the front and rear sections, the funnel shaped member further having an outlet end through which material to be dispensed from the container flows, one of said funnel shaped member cylindrically inner surface and tubular body member outer surface defining a cam surface and the other of said surfaces defining a cam lobe follower, the cam surface extending circumferentially about the tubular body member from at least one high point to at least one low point, the low point being positioned at a greater distance from the pouring end of the tubular body member than the high point so that rotation of the funnel shaped member in either direction relative to the tubular body member causes the outlet end of the funnel shaped member to move toward and away from the pouring end of the tubular body member, the tubular body and funnel shaped members having cooperating closure means comprising a stopper member mounted on the pouring end of the tubular body member for sealingly engaging the taped section of the funnel shaped member when the outlet end of the funnel shaped member is moved toward the pouring end of the tubular body member the maximum distance allowed by the cam surface and the cam lobe follower.
