ABSTRACT:
A method of manufacturing a metallic can formed like a case container, comprising forming a four-fold seamed edge portion by folding and seaming by adhesive means edges of a sheet for building a can body. The four-fold seamed edge portion is included in a curled and seamed portion which is formed by curling and pressing the flanged edge portion of an end plate together with the marginal portion of the can body. All layers of the seamed sheet are tightly joined opposite each other in the curled and seamed portion, thus hermetically sealing a finished can.
