An extendable spout for a container formed of blown plastic in which the top of the container is formed of convoluted plastic which may be nested into the container. This eliminates the protruding spout when the container is being shipped to save the space but the spout may be extended from the container by expanding the convolutions to form a convenient pouring spout or funnel. The bottom of the container is likewise formed of convoluted plastic and the convolutions expand for extending the bottom into the container to compensate for the volume added to the container by the spout when the latter is extended.
