Definitions

  • the subject of the invention is a device for wedging an object made of honeycomb cardboard and corrugated cardboard and a packaging box receiving this wedging device.
  • the transport of an object requires the use of wedging devices in order to avoid deterioration of the transported object.
  • the wedging devices are made of polystyrene which has the advantage of being light, easy to mold and not very abrasive.
  • Certain molded cellulose wedging devices have thus been developed. This material, which is essentially made from recycled paper and water, nevertheless has the drawback of being heavy, difficult to mold into complex shapes, abrasive and generates dust.

  • Honeycomb cardboard wedging devices are also known.
  • the latter is formed of two parallel sheets of paper between which stand a plurality of sheets of paper substantially perpendicular to the two parallel sheets of paper.
  • the cellular board although relatively bulky, has good impact resistance in a direction perpendicular to the two parallel sheets but much lower impact resistance in a parallel direction.
  • a sheet of honeycomb cardboard can be stamped (crushed) perpendicular to the planes of the parallel sheets of paper in order to accommodate an object. This stamping makes the cellular board resilient, promoting shock absorption, but decreases the overall strength of the cellular board. It is also necessary to protect the objects to be wedged against abrasion, in particular when it is in contact with the edges of a recessed or stamped part of a cellular cardboard plate.
  • corrugated cardboard can also be used, but its impact resistance and shock absorption capacity are relatively limited.
