Abstract
A metallic container composed of a first and a second section each composed of a metallic cup-like fabricated article having a primer coating, the two sections being lap-bonded at their circumferential open end portions by means of a thermoplastic film-like adhesive. A process for producing said metallic container is also provided which comprises a fabricating step of producing the first and second sections, an adhering step of heat-adhering a film-like adhesive to the peripheral surface of the open end portion of the second section to be laid inwardly, and a bonding step of bonding the open end portions of the first and second sections. In the metallic container, the film-like adhesive, forming a circumferential overlapping portion, is adhered to the edge of the open end portion of the second section and its inner circumferential surface following the edge.
