However, what was molded was used to partition the objects, such as machines, products, fruits, vegetables, and other articles to be packed, while matching the shapes. As described above, the conventional partitioning member 1 is formed by molding a synthetic resin such as cardboard or styrofoam resin in advance for each object to be packaged according to its shape using a mold.

[0003]

By the way, the following problems have been pointed out in such a conventional example. First of all, as the objects to be packed in the packing box, various shapes such as machines, products, fruits, vegetables, and other articles can be considered. There is a problem that it is inconvenient because it is necessary to mold and process each of various shapes in advance. That is, the conventional partition material 1
Has been pointed out that it is inconvenient due to its lack of versatility because it is used exclusively for each packaged object. Secondly, and for the same reason, it is necessary to prepare various molds for molding each partition 1, and it takes time and time to mold the partition 1 using such a mold. Moreover, it has been pointed out that there are problems in terms of cost and time, such that it may be time-consuming to use.

Thirdly, with respect to the partition material 1 in which cardboard is used as the material, when the impact load is applied from the outside, the strength is insufficient and the pressure resistance is poor, and the cushioning is insufficient because the impact load is not sufficiently absorbed and absorbed. There was a problem in the protection of the items to be packed, such as insufficient capacity. Fourthly, on the other hand, the partitioning material 1 made of a synthetic resin such as styrene resin has poor air permeability and hermetically seals objects to be packaged. Therefore, the objects to be packaged such as fruits and vegetables are easily damaged. there were.

In view of the above situation, the present invention has been made to solve the problems of the above-described conventional example, in which a substantially strip-shaped honeycomb core is partially curved, inverted, and abutted.

The state is held by the shape holding means, and the outer cell end surface is directed to the object to be packed and is sandwiched between the objects to be packed along the shape.

[0007]

Since the present invention comprises such means, it operates as follows. The partition member is used while the substantially core-shaped honeycomb core is partially curved, inverted, and brought into contact with the partition member while being held by the shape holding unit. Then, with respect to the plurality of packing objects housed in the packing box, the cell end faces on the outside are directed to the packing objects, and the packing objects are sandwiched and set so as to partition the packing objects.
