Vessel with pouring spout inducing constant geometry, non-turbulent stream and vented closure for same

U.S. Patent Number: 5388732

Abstract: A vessel having a bottom with a vertical center-line and an annular side wall extending upward from the bottom of the vessel terminating into a rim portion. The vessel is further provided with at least one pouring spout formed in the side wall and extends peripherally about the side wall for at least a 75 degree arc with respect to the vertical centerline of the bottom. The pouring spout consists of two opposing concave upper pouring spout surfaces which converge upon and join a concave lower throat surface. The pouring spout thus provides a cross-sectional flow pattern initially in the shape of a convex-sided V that reforms into a round non-turbulent stream regardless of the flow rate of the liquid being poured. A complementary closure having at least one array of openings, for venting steam and/or straining liquids being prepared in the vessel is also disclosed.
