a spill - proof pour spout for transferring fluid from a container to a vessel comprising a base having an inner sleeve extending outwardly therefrom , a conduit member located in the inner sleeve , and an outer sleeve slidingly engaging the inner sleeve . the conduit member has a fluid tube , and air tube and an end cap . the outer sleeve is in a first closed position wherein the outer sleeve contacts the end cap preventing fluid flow from the pour spout . the pour spout can only be opened by rotating the outer sleeve to a first or second indexing position . by rotating the outer sleeve either clockwise or counterclockwise relative to the inner sleeve , the outer sleeve is adapted to be slid to a first open position permitting fluid to flow at a first flow rate through the fluid tube and out of the pour spout . by further rotating the outer sleeve either clockwise or counterclockwise , the outer sleeve is adapted to be slid to a second open position permitting fluid to flow at a second flow rate through the fluid tube at a second flow rate and out of the pour spout .
