  • 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: 9669932
    Abstract: A display for viewing by a passenger from a seat on a vehicle when the display is mounted to structure in front of the passenger when the passenger is seated in the seat. The structure has a recess and a portion surrounding the recess. The display includes an electronic visual display panel for receiving a display signal and displaying information in correspondence therewith to the passenger on the electronic visual display panel. The display further includes a housing in which the electronic visual display panel is mounted or inserted, with the housing including a periphery. At least one fastener is provided including a structural fuse. The structural fuse deforms and/or fractures under force generated by a passenger's head striking the visual display panel in an accident. Due to crumple of the fuse, movement of the housing is permitted, with the display panel inserted therein, relative to the recess.
