Abstract
An extrusion blow molded container is provided having an integrally formed generally annular pouring lip including an upwardly facing convex surface beginning at a generally vertical inner wall of the container and curving through an arc of less than 180 degrees. The lip is undercut forming a sharp downwardly directed annular edge on the lip. The lip can be formed by cutting the lip with a downwardly curved cutting tool bearing against an upwardly curved anvil, the cutting tool forming the upwardly facing convex surface of the lip and the anvil forming the undercut lower surface of the lip.
