Bottom seam for a pail

Abstract From the Canadian patent

A pail body having a longitudinal axis and an open end has an end wall fitted in the open end said fitting, involving outward bending of a flange at the open end of the pail body and interengagement of this body flange with a flange on the end wall introduced into the open end of the pail body. A region of the pail body adjacent the body flange is formed so that it is outwardly inclined with respect to the axis of the pail body at a small angle (e.g. from 4° to 12°), said angle corresponding to the angle of taper on a tapering rim part on the end wall introduced into the open end of said pail body thus promoting close contact between said body region with said tapering rim part.
