The present invention may be used for insertion in and coupling with a neck of an open bottle (62) that may have a fluid (64) therein. A pour spout (10) may have a conduit (12) therethrough. A coupling portion (20) of the pour spout (10) may have a generally hollow cylindrical form that may form a portion of the conduit (12). An outer wall (22) may have an intake flange (24) at an intake end (26) and an opening flange (28) adjacent an annular lip member (14). The outer wall (22) may have a flat portion (30) and the intake flange (24) may have a corresponding flat portion (32). A coupling sleeve (34) may be disposed on the coupling portion (20). A discharge portion (40) of the spout (10) may have a generally half spherical member (42) that may have a bore (44) therethrough. The bore (44) may form a portion of the conduit (12) and the half spherical member (42) may abut the annular lip member (14). The half spherical member (42) and the opening flange (28) may have a pressure equalization duct (50) therethrough that may be parallel to and adjacent to the conduit (12). An exit opening (52) of the pressure equalization duct (50) may be positioned adjacent to the flat portion (30).
