The flow path is provided with a Venturi constriction, and a Venturi intake port delivers ambient air to the low pressure zone of the constriction, as is generally known in the prior art. A closure member is pivotally joined to the spout, with a distal end that rotates to seal the spout outlet, and rotates open as the spout is tipped to a pouring position. A filter is removably secured in the proximal end of the bore in the spout to remove sediment from the wine. ## Claims ### Claim 1 A pouring spout for pouring liquid from a container while simultaneously aerating the liquid discharged from the spout outlet opening 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 closure member for sealing said outlet opening when said spout is upwardly oriented, said closure member being rotatable to unblock said outlet opening when said spout is tipped to a pouring position. ### Claim 2 (depends on 1) The pouring and aerating spout of claim 1, wherein said closure member includes a distal end having a configuration adapted to seal said outlet opening. ### Claim 3 (depends on 2) The pouring and aerating spout of claim 2, further including a pivot shaft extending from said spout to pivotally support said closure member, said closure member including a proximal end that comprises a counterweight to said distal end in rotation about said pivot shaft. ### Claim 4 (depends on 3) The pouring and aerating spout of claim 3, wherein said proximal end includes a loop portion that circumscribes a distal portion of said spout and is spaced apart therefrom. ### Claim 5 (depends on 4) The pouring and aerating spout of claim 4, further including a pair of support arms extending from opposed ends of said loop portion to said distal portion of said closure member, said support arms being spaced apart and said distal portion of said spout being disposed between said support arms. ### Claim 6 (depends on 5) The pouring and aerating spout of claim 5, further including stop means for limiting rotation of said closure member about said pivot shaft when said spout is tipped to the pouring position. ### Claim 7 (depends on 6) The pouring and aerating spout of claim 6, wherein said stop means includes at least one stop lug extending outwardly from said distal portion of said spout and disposed in the rotational path of a portion of at least one of said support arms. ### Claim 8 (depends on 1) The pouring and aerating spout of claim 1, wherein said liquid flow path includes a proximal intake opening, and further including a filter dimensioned to be removably secured in said proximal intake opening. ### Claim 9 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 from a proximal intake opening 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 liquid filter for removing sediment and particulates from liquid passing through the spout, said liquid filter being removably secured in said proximal intake opening. ### Claim 10 (depends on 9) The pouring spout of claim 9, wherein said liquid filter includes a curved sidewall extending generally about a longitudinal axis, said curved sidewall defining a filter intake opening. ### Claim 11 (depends on 10) The pouring spout of claim 10, wherein said curved sidewall is dimensioned to substantially span said proximal intake opening, whereby said liquid flow path extends through said filter intake opening. ### Claim 12 (depends on 11) The pouring spout of claim 11, wherein said curved sidewall includes a plurality of small holes extending therethrough to enable liquid flow while blocking particulates and sediment. ### Claim 13 (depends on 12) The pouring spout of claim 12, wherein said proximal intake opening includes a planar secant surface extending longitudinally, and said liquid filter includes a base panel extending longitudinally and disposed to impinge on said planar secant surface when said filter is installed in said proximal intake opening. ### Claim 14 (depends on 12) The pouring spout of claim 12, wherein said filter further includes a stop flange for limiting the position of said filter in said proximal intake opening. ### Claim 15 (depends on 12) The pouring spout of claim 12, further including a proximal portion of said filter having a lip projecting therefrom as a finger pull to enable removal of said filter from said proximal intake opening. ### Claim 16 (depends on 12) The pouring spout of claim 12, further including a spout outlet opening for pouring the liquid, and a closure member for sealing said outlet opening when said spout is upwardly oriented, said closure member being rotatable to unblock said outlet opening when said spout is tipped to a pouring position.
