Claim:
A pouring spout for pouring liquid from a container while simultaneously aerating the liquid discharged from the spout and including a tubular body having a liquid flow path extending longitudinally therethrough and a Venturi constriction located in the flow path and a Venturi air intake opening into the Venturi constriction to aerate the liquid as it flows therethrough, the improvement comprising: a displacement air channel extending from an exterior portion of said pouring spout to an interior portion of the container to enable a flow of air to replace a mass of liquid discharged from said spout; said displacement air channel including a displacement air intake opening to the exterior portion of said spout, said displacement air channel extending from said displacement air intake to the interior of the container; said Venturi air intake extending to the exterior portion of said spout adjacent to said displacement air intake; a housing extending outwardly from the exterior portion and including an ambient air intake to supply air to both said Venturi air intake and said displacement air intake; said housing also comprising means to direct any drops of liquid from said Venturi air intake retrograde into said displacement air intake and thence through said displacement air channel to the interior of the container.
