    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.

    摘要： Disclosed is a hot-melt adhesive which comprises a copolyester of a dibasic acid component comprising 70 to 97 mole % of terephthalic acid and other dibasic acid with a polyhydric alcohol component comprising 70 to 97 mole % of 1,4-butane-diol, 3 to 30 mole % of diethylene glycol and up to 20 mole % of other polyhydric alcohol having 2 to 5 carbon atoms, said copolyester having a reduced viscosity of at least 0.6 dl/g as measured at a temperature of 30.degree. C. in a phenol/tetrachloroethane mixed solvent having a phenol/tetrachloroethane weight ratio of 60/40 at a polymer concentration of 0.25 g/100 ml, a glass transition temperature of at least 31.degree. C. and a crystallinity of 15 to 40 %.This hot-melt adhesive is excellent in the operation adaptability, and in the form of a film, the adhesive has an appropriate rigidity and a good dimension stability. Furthermore, when this hot-melt adhesive is formed into an adhesive layer between seams by hot bonding, the adhesive layer provides a high creep resistance and a good dimension stability. This hot-melt adhesive is valuably used for producing a metal vessel having a circumferential side seam by bonding cup-shaped lower and upper members along circumferential open ends of the two members.
