摘要：
To ensure sealing ability of a resealable can container formed of a welded can body between a curled portion of container mouth and a resin sealing liner, without degrading productivity and easiness to open the closure.
The can body 2 is prepared by rolling a steel sheet and welding overlapped longitudinal edges of the steel sheet. In order to achieve the above-mentioned objective, a level difference of a welded portion 2a on the surface of a curled portion 21a is reduced smaller than that on the trunk portion 22, specifically, kept within the range of 15 to 100 µm, and a durometer hardness of the resin sealing liner is kept within the range of HDA 30 to 70 according to ISO 868 (or JIS-K7215).
