METAL CONTAINERS

摘要

An improved metal container of three piece construction with a welded longitudinal body seam, having on its upper part an outward flaring flange to allow the double-seaming of the top end after filling the container. The bottom end is assembled from the inside over an inward turned body edge to form a labyrinth configuration with adjacent layers of material inside a rim. The rim has a substantially toroidal configuration with the lower edge of the can body forming convolutions that are alternate and adjacent with the edge and are not parallel with the base plane.
