C. at least when the sealant is first applied, the step (B) of applying the sealant at a viscosity of 50-200 centipoises at 50.degree. C. at least when the sealant is first applied, the step (C) of after the sealant is applied, blowing cold air at a temperature of up to 10.degree. C. to the band seal to cool the band seal below 10.degree. C., the step (D) of reducing the joint distance between the body and the cap shorter than the standard capsule length, and the step (E) of applying the sealant to only an edge adjacent portion of the cap surface when the sealant is first applied.
