US Patent 7299743 Aerating decanter with dispensing valve

This invention combines several processes into on easy to use product. The glass sphere dramatically enhances the aeration procedure by gently exposing air to thin waves of wine as wine passes over the surface of the sphere. The integrated filter provides a larger surface than normally found in wine filtration devices. The supporting structure secures the decanter in such a way that consumers can easily dispense wine without handling a wine bottle or conventional decanter.
