  • Publication number: 20240327089
    Abstract: A package is provided which is formed by, with a commodity sandwiched between single-faced corrugated paperboards that are vertically disposed paper members, pressure-bonding together the paper members at the edges of the paper members along the peripheral sides thereof. The edges of the single-faced corrugated paperboards along at least two opposed sides thereof are subjected to waveform bonding by pressure bonding such that a wave shape is formed in the thickness direction of the single-faced corrugated paperboards. The dimensional difference between (i) the length L1 of the portion of each paper member deflected by sandwiching a commodity, and (ii) the flat-bonding length (imaginary linear distance) L2 of a respective one of the edges extending parallel to the direction of the length L1, and each imaginarily bonded flat is absorbed by the waveform bonding, so that, at these edges, the vertical gaps between the single-faced corrugated paperboards are eliminated.

  • 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.
