  • Patent number: 10525520
    Abstract: 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.

  • Patent number: 10518925
    Abstract: The objective of the present invention is to provide a molded paper body in which the outer peripheral portion of a blank primarily of paper is formed in a raised shape using draw processing, wherein the molded paper body eliminates the occurrence of wrinkles causing leaking or instability of adhesion when used as the bottom member of a paper cup or similar paper container and a forming method thereof. The method for manufacturing this molded paper body is to draw-process, with a punch and die, a single blank primarily of paper, and is characterized by use of a holding mechanism to press the outer peripheral portion of the blank between a wrinkle pressing member and the die upper surface, and setting the force applied by the wrinkle pressing member within an appropriate range.
