Abstract:
1. A bottle aerator having a venturi tube having a constricted section with a narrower cross-sectional section and a fluid inlet section having a wider cross-sectional section, and further including a liquid outlet section having a wider cross-section than the constricted section, such that the fluid pressure is lower in the constricted section compared to the pressure in the fluid inlet section, and the fluid speed is higher in the constricted section compared to the fluid speed in the fluid inlet section, the venturi tube constructed and arranged to be removably engaged to a bottle to form a liquid seal and for incorporating ambient air into a liquid stream as the liquid is poured from the bottle, the improvement comprising: the constricted section being constructed and arranged so that when the bottle aerator is inserted into the bottle, the constricted section is positioned inside the bottle, further including at least one air tube extension located alongside the venturi tube, the at least one air tube extension is in fluid communication with air outside the bottle, the air tube extension having an air outlet opening into the interior of the bottle, the venturi tube further including at least one air outlet which is provided at or below the constricted section, the lower pressure in the constricted section creating a partial vacuum which pulls air from outside the bottle to mix with the fluid before it passes through the constricted section, so that the fluid is aerated while still inside the bottle.
