Abstract:
A method for producing a screw-top bottle-can and a screw-top bottle-can are provided so that a screw-thread can be formed without damaging an inner coating and a resealing operation can be improved. A shoulder part is formed by reducing a diameter of an opening part of a closed-end cylindrical body, a cylindrical part having an intermediate diameter between a major thread diameter and a minor thread diameter and a tapered part which is tapered from an upper end of the cylindrical part toward an opening-end part are formed above the shoulder part, and forming a screw-thread from the tapered part to the cylindrical part so as to form a starting part of the screw-thread at a middle part of the tapered part.
