A container for storing and dispensing viscous liquids which dispenses from the bottom of the container and which has a self-closing, non-drip dispensing spout. The dispensing spout may be provided on the bottom of an upright container having a cap at the other extremity or as a part of a removable cap for the container having a flat upper surface for storing the container in an inverted position. A self-operating closure allows one-handed operation of the container. The self-operating closure has a pivotable dispensing tube and valve with an open position and a closed position which is operated by the pivoting action of the dispensing tube. The pivotable dispensing tube and the valve are biased into a closed position to make the closure self-operating. A detent may be provided for holding the pivotable dispensing tube in an open position against the bias. The closure is operated by urging the pivotable dispensing tube past the detent, either manually or by setting the dispensing bottle down on a horizontal surface, whereupon the dispensing tube and therefore the valve are urged to a closed position. The fluid passage through the pivotable dispensing spout is configured so that, when the dispensing spout is in the closed position, any fluid within the passage will tend to flow back toward the closed valve instead of dripping from the end of the dispensing tube.
