A retractable spout assembly for application to the neck of a bottle includes: a sleeve-like housing fixedly receivable within the bottle neck; a spout movable within the housing from a retracted position, when the housing is fixed within the bottle neck and the bottle neck closed by the cap, to an extended position projecting outwardly of the housing and the bottle neck for pouring out contents of the bottle; and an air-return passageway for returning air into the bottle when contents therefrom are being poured out through the spout. The air-return passageway is fixed with respect to the housing such that it does not change its position during the extension and retraction of the spout. The housing is formed with a plurality of holes adjacent its inner end to enable complete emptying of the bottle. The outer surface of the spout is tapered, and the outer end of the housing is formed with an outwardly-extending annular flange configured to define an annular channel for catching drippings of the spout, and for returning the drippings into the bottle when the spout is moved to its retracted position.
