Described herein are methods for texturizing metal, closed-end, cylindrical workpieces or capsules. A texturizing apparatus that includes a texturizing sector and a texturizing spindle tip is disclosed. The metal, closed-end, cylindrical workpieces or capsules are placed onto the texturizing spindle tip that includes a texture. A pressure is applied to the texturizing sector and the metal, closed-end, cylindrical workpiece or capsule, and the texturizing spindle tip is rotated against the texturizing sector to impart an image of the texturizing spindle tip texture to the metal, closed-end, cylindrical workpiece or capsule. The texturizing sector may include a smooth surface and a resilient material, and the texturizing spindle tip may include a textured surface and a non-resilient material. The texture of the metal, closed-end, cylindrical workpiece or capsule includes the imparted image of the texturizing spindle tip texture.

An apparatus and tool set forming a three-dimensionally shaped portion on a shoulder of a can including an inner roll having a receiver for receiving the shoulder from inside; an outer roll for pressing the shoulder from outside; and a rotating unit for rotating the inner roll and the outer roll relative to the can. The shoulder is formed on a side of an upper end of a cylindrical body of the can in a can axis direction to be reduced in a diameter toward a side of a mouth of the can and to have a thickness of 0.1 to 0.3 mm. The receptor of the inner roll has at least one of a concave portion and a convex portion, and has a diameter reduced portion corresponding to a shape of the shoulder. Further, the inner roll and the outer roll are rotated by the rotating unit.

A can is provided. The can may include a shoulder, which is formed on a side of an upper end of a cylindrical body of the can in a can axis direction to be reduced in a diameter toward a side of a mouth of the can and to have a thickness of 0.1 to 0.3 mm, and has at least one of a concave portion and a convex portion. An inside diameter of the mouth may be 25 to 60 mm, a maximum outside diameter of the shoulder may be 50 to 70 mm, and a ratio of the maximum outside diameter of the shoulder to the inside diameter of the mouth may be 1.05 to 1.58.

A can 1 is provided with a mouth part (4), a shoulder part (3), and a body part (2). The shoulder part (3) of the can (1) is decorated, without damaging the shoulder part (3), by forming at least one of a recess and a protrusion by a rotating process in which the shoulder part (3) is held between a receiver (11a), having a concave-convex shape, of an inner roll (11) and an outer roll (12) having a convex-concave shape corresponding to the concave-convex shape of the receiver (11a) of the inner roll (11).
