The present invention may be used for insertion in and coupling with a neck of an open bottle that may have a fluid therein. A pour spout may have a conduit therethrough. A coupling portion of the pour spout may have a generally hollow cylindrical form that may form a portion of the conduit. An outer wall may have an intake flange at an intake end and an opening flange adjacent an annular lip member. The outer wall may have a flat portion and the intake flange may have a corresponding flat portion. A coupling sleeve may be disposed on the coupling portion. A discharge portion of the spout may have a generally half spherical member that may have a bore therethrough. The bore may form a portion of the conduit and the half spherical member may abut the annular lip member. The half spherical member and the opening flange may have a pressure equalization duct therethrough that may be parallel to and adjacent to said conduit. An exit opening of the pressure equalization duct may be positioned adjacent to the flat portion.
