  • Patent number: 10427828
    Abstract: A corrugated paperboard box is provided in which when flaps are bent, a perforated line along which the flaps can be separated from the box is less likely to break. Such a corrugated paperboard box includes a peripheral wall and top flaps, and is formed, at the boundary area between the peripheral wall and the top flaps, with a groove-shaped reverse scoreline recessed on the side of an outer linerboard, and a pair of groove-shaped recesses recessed on the side of an inner linerboard, and extending in parallel to each other so as to sandwich the area in which the reverse scoreline extends. The corrugated paperboard box is further formed, in one of the groove-shaped recesses, with a perforated line along which the top flaps can be separated from the peripheral wall. The top flaps can be bent along the perforated line toward the inner surface of the peripheral wall.

  • Patent number: 10370769
    Abstract: In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.
