Capped bottle-shaped can and manufacturing device thereof

The utility model provides a bottle-shaped can which is excellent in sealing performance and uncovering performance. The top part (8a) is provided with a top end (8b) serving as the upper end of the neck part (4), an outer diameter maximum part (8c) which is located below the top end (8b) and has the maximum outer diameter, a rolling-in part (8d) which is continuous from the outer diameter maximumpart (8c) to the lower side and has the outer diameter gradually decreased, and an outer peripheral wall part (8e) connected with the rolling-in part. The tip (8b), the maximum outer diameter section(8c), and the winding section (8d) form a smooth curved surface. The curvature in a cross-section of an outer peripheral wall section (8e), which includes a planar cross-section of the central axis (Lc) of the neck section (4), is set to "0" or "negative" when the curvature of the rolled-in section (8d) is set to "positive". An inflection section (8f) is formed between the winding section (8d) and the outer peripheral wal
