    摘要： Disclosed is a metal vessel comprising upper and lower members, each of which consists of a seamless molded metal cup having a protecting resin cover layer, the open end portions of the upper and lower members being lap-bonded to each other through an adhesive to form a circumferential side seam, said metal vessel being characterized in that the open end portion defining the inner side of the circumferential side seam has a layer of a thermoplastic resin adhesive tape heat-bonded along the entire circumference of said end portion while wrapping the end edge and adjoining inner and outer side faces therein, a layer located on the outer side face of the adhesive tape is extended along the lap-bonded portion, and the adhesive layer present in the lap-bonded portion satisfies the following requirement: wherein S 1 stands for the sectional area (mm 2 ) of the adhesive layer present in the lap-bonded portion, eo stands for the width (mm) of the lap-bonded portion, and to stands for the thickness (mm) of the adhesive tape present on the inner side of the inner open end portion.
