Method of forming a vessel pouring spout.

摘要

A method for forming a constant geometry and non-turbulent stream inducing pouring spout (10) in the rim portion (8) of a annular side-walled vessel (2). The method comprises the steps of: a) positioning the vessel within a clamping means (30) possessing a groove whose centerline forms a 90 DEG angle with the annular side wall of the vessel when the clamping means is in place; b) placing inside the vessel a center plug means (32) possessing a radially extending groove (42) whose centerline forms a 90 DEG angle with the annular side wall (6) when the center plug means is in place; c) aligning the centerlines of the grooves of the clamping means and the center plug means to form a straight line travel path; d) placing a pour spout forming means in the center plug portion's groove and causing the forming means (31) to travel along the travel path and into contact with the rim portion of the vessel; and, e) further causing the forming means to travel along the travel path to yieldably deform the rim portion of the annular wall into the desired shape pouring spout. The actual deformation of the rim (8) takes place in three stages. The first stage and third stages involve deforming the rim portion by the forming means in an outward and upward direction and an outward and downward direction, respectively, while the second stage involves deforming the rim portion in only an outward direction. <IMAGE>
