An assembly for containing and dispensing a liquid, comprising: a container for containing the liquid; and a liquid dispensing device comprising: a spout through which the liquid can pass out and air can come in; means for filtering the liquid and the air passing through the spout; a cap for closing the container; and means for encouraging entry of air and/or return of a residual quantity of the liquid trapped in the spout after dispensing some of the liquid, through the means for filtering, into the container, wherein the means for encouraging entry of air and/or return of a residual quantity of the liquid comprise means for sealing capable of closing in a sealed manner a space located between the spout and the partially-closed cap, a volume of which decreases as closure of the cap progresses, so as to create an overpressure in the spout downstream of the filtering means, due to the cap being closed.
