摘要： A metal vessel has a metal bottomed cup-shaped lower member and a metal cup-shaped upper member, the upper and lower members being bonded together by a circumferential side seam. The upper member has a pouring mouth having a small diameter in the central portion thereof. The metal vessel is formed by lap-bonding the circumferential open ends of both the upper and lower members. The side wall of the upper member is formed by subjecting a primer-coated tin-plated steel sheet to draw forming at a side wall plastic forming ratio R of from 1.1 to 1.8; the side wall plastic forming ratio R being defined by the following formula: ##EQU1## wherein W stands for the weight (g) of the blank of the upper member, t stands for the thickness (cm) of the blank of the upper member at the side wall, .rho. stands for the density (g/cm.sup.3) of the blank of the upper member, D.sub.0 stands for the inner diameter (cm) of pouring mouth of the upper member, and D.sub.1 stands for the average inner diameter (cm) of the side wall.In the circumferential bonded portion, the side wall of the lower member is bonded to the side wall of the upper member through an organic adhesive interposed between a primer coating applied to the side wall of the lower member and a primer coating applied to the side wall of the upper member. The bonding strength and resistance to leakage of the lap-bonded circumferential side seam are improved.
