Abstract:
PROBLEM TO BE SOLVED: To prevent contents from spouting out of a metallic bottle can whose inside cannot be seen.SOLUTION: A bottle can has a shoulder part 6 which decreases in diameter from a body part 5 of a can body 1 having a can axis C in the center toward an upper end side, a neck part 7 extending from the shoulder part 6 toward the upper end side, and a cap fitting part 8 having an opening part 4 on an upper-end side of the neck part 7. The shoulder part 6 has, in a cross section along the can axis C, a convex curve part 6a which draws a convex curve swelling to an outer peripheral side of the can body 1, and a concave curve part 6c which draws a concave curve recessed from a lower end of the neck part 7 to an inner peripheral side and connected to the convex curve part 6a directly or through a straight line part 6b. When an extension M crossing the neck part 7 in contact with an inner peripheral edge of the opening part 4 is rotated toward the lower end side in contact with the inner peripheral edge of the opening part 4, an inner peripheral surface of the shoulder part 6 crosses the extension M always at one point, or the straight line part 6b is formed in an overlapping state.SELECTED DRAWING: Figure 5
