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.

  1. 1. A vessel comprising:a) a vessel bottom having a vertical center-line;b) an annular side wall extending upward from the vessel bottom and terminating into a rim portion and having an inside diameter of at least 4.5 inches;c) at least one pouring spout formed in the side wall and extending peripherally about the side wall for about a 90.degree. arc with respect to the vertical center-line of the bottom, the at least one spout being peripherally centered about a bisect-line of the arc;d) the at least one pouring spout being defined by the rim portion making a transition into opposing convex tipper pouring spout surfaces which possess a radius of curvature, indicated as R1, determined by the equation R1=1.44D-4.96 and which converge upon and intersect with a concave lower throat surface having a lower most portion and a radius of curvature, indicated as R2, determined by the equation R2=0.52D-2.11 the lower most portion of the concave lower throat surface being positioned a predetermined distance below the rim portion of the side wall, the predetermined distance, indicated as H, is determined by the equation H=0.005D +0.516 wherein D is the inside diameter of the vessel; ande) the at least one pouring spout having a lip extending outwardly away from the side wall, the lip having a predetermined curve profile with vertical and horizontal components, the horizontal component of the curve profile of the lip in the vicinity of the bisect-line of the arc occupied by the spout includes a radius of curvature, indicated as R3, determined by the equation R3=0.5D-1.97 and a predetermined length that varies as a function of peripheral distance from the bisect-line of the arc occupied by the at least one pouring spout in such manner to provide the lip with a maximum length at the bisect-line of the arc and a minimum length where the concave upper pouring spout surfaces respectively transition into the rim portion.
