POLYGONAL CAN AND METHOD FOR FORMING THEREOF |
| 摘要 |
Provided is a polygonal in which a decoration effect equivalent to that of a cylindrical base-can is obtained without causing folding or deformation in a can body-part. Bottom-part outer-peripheral parts (A-2) of a cylindrical base-can that are expected to form linear parts (B-2) of a polygonal can (B) are moved inward in a radial direction, while bottom-part outer-peripheral parts (A-1) of the cylindrical base-can that are expected to form corner parts (B-1) of the polygonal can are moved outward in the radial direction. Thus, the polygonal can is molded such that the body-part cross-section peripheral length of the cylindrical base-can and the body-part cross-section peripheral length of the molded polygonal can have a substantially isometric relationship. |

1. A polygonal can formed from a cylindrical base-can having a body part and a bottom part, wherein
a bottom-part periphery and a body-part cross-sectional surface each have a substantially polygonal shape having linear parts and corner parts, and a body-part cross-section peripheral length of the cylindrical base-can and a body-part cross-section peripheral length of the formed polygonal can have a substantially isometric relationship. |
