  Conventionally, various units and cartridges to be used in image forming apparatuses such as copying machines and printers are stored in a packing box made of cardboard and transported or stored. Has been done.

  In order to prevent the packaged items such as various units and cartridges from being stored in the packaging box, the packaged items are prevented from being damaged by the impact of the packaged items. When a container is accommodated in a packaging box, a corner cushioning material is attached to each corner portion of the packaged item to mitigate the impact applied to the packaged item.

  Here, as the corner cushioning material to be attached to the corner portion of the article to be packed, generally, as shown in FIG. 1, the corner cushioning material 1 in which the concave portion 1a into which the corner portion of the article to be packaged 2 is fitted is formed up and down. A pair is used.

  Then, when mounting such a pair of corner cushioning materials 1, 1 on each corner portion of the article 2, as shown in FIG. 2, the recesses 1 a, 1 a in the pair of corner cushioning materials 1, 1 are provided. The pair of corner cushioning materials 1 and 1 are arranged above and below the corner portion of the article to be packed 2 so that they face each other, and the article to be packed is placed in the recesses 1a and 1a in each corner cushioning material 1 and 1. The corner portions of the article to be packed 2 are sandwiched in the vertical direction by the pair of corner cushioning materials 1, 1.

  In addition, when the packaged material 2 is accommodated in the packaging box 3 by attaching the pair of corner cushioning materials 1 and 1 to the corners of the packaged product 2 as described above, As shown in FIG. 3 and FIG. 4, the flat portion 1 b of each corner cushioning material 1 so that the concave portion 1 a of each corner cushioning material 1 is positioned on the upper surface side at each corner of the bottom portion 3 a of the packaging box 3. And the side wall 1c is brought into contact with the packing box 3, and in this state, the corners of the above-described packaged objects 2 are fitted into the recesses 1a of the cushioning materials 1 for the corners, and the packages 2 are used for each corner.

Therefore, there is also a problem that it is not possible to sufficiently suppress the to-be-packaged item 2 from rattling in the vertical direction.

  Further, in recent years, ribs for partially holding the corner portions of the packing items are provided in the concave portions of the pair of corner buffer materials for mounting the corner portions of the objects to be packed, and the corner buffer materials that come into contact with the packing box are provided. Ribs have also been provided on the side wall portions of the slab, and the impact applied to the packing box due to the deformation of these ribs is absorbed to mitigate the impact applied to the object to be packed (for example, Patent Document 1). reference.).

However, even in the above-described corner cushioning material, the upper and lower surfaces of the corner portion of the packaged object are sandwiched between the pair of separated corner cushioning materials, so that the packaged object is accommodated in the packaging box. In this case, as in the case of the pair of corner cushioning materials 1 and 1, it is difficult to accurately set the article to be packed on each corner cushioning material. There is still a problem that the packaged item may be set in a tilted state without being set well on the material, and the backlash of the packaged item cannot be sufficiently suppressed.
