Claim 1
Independent Claim
176 words
A metal bottle adhesive for lap-bonding upper and lower members, each consisting of a cup-like formed article of a metal, on the peripheral ends thereof, said adhesive comprising at least one high-molecular-weight thermoplastic resin having a post crystallinity ΔWc, defined by the following formula, of less than 20%: ΔWc=Wc.sub.II =Wc.sub.I wherein Wc I stands for the crystallinity (%) of the adhesive which has been molten at a temperature higher by 30° C. than the softening point thereof and then naturally cooled at room temperature, determined according to the density method, and Wc II stands for the crystallinity of the adhesive which has then been immersed in water maintained at 70° C. for 10 hours and then naturally cooled and dried at room temperature, determined acoording to the density method, a shear creep compliance J(t) t=2 hrs of less than 10 -4 cm 2 /dyne at 90° C. and a time constant of 2 hours and a concentration of ##STR9## groups, contained in the main or side chain, of 10 to 1400 meq/100 g of the resin.
