To do. The gap formed between the inner peripheral surface of the lower part of the vertical through hole a3 of the article A and the outer peripheral face of the article lower support member 3 is preferably as narrow as possible. Thus, even if the gap formed between the inner peripheral surface of the through hole lower portion of the vertical through hole a3 of the article A and the outer peripheral surface of the article lower support member 3 is narrowed, the articles A are individually one by one. In addition, since the operator is fitted to the article lower support member 3, the work of fitting the article lower support member 3 to the lower through hole of the vertical through hole a <b> 3 of the article A is troublesome, There is no such thing as long working hours. In this way, the article A is fitted to all the article lower support members 3 protruding from the bottom 1a of the article lower storage recess 1 of Dungege.

As described above, the gap formed between the inner peripheral surface of the lower portion of the vertical through-hole a3 of the article A and the outer peripheral surface of the article lower support member 3 is narrowed to fit the article lower support member 3. The looseness of the combined article A can be suppressed as much as possible. Therefore, as described later, when another dunnage is stacked on the article A stored in the dunnage, the stacked dunnage is stacked. The wobble can be reduced, and the dunnage in which the articles A are stored can be stacked in a stable state.

Next, the article A stored in the dunnage in a state where the article A is fitted to all the article lower support members 3 protruding from the bottom 1a of the article lower storage recess 1 (hereinafter referred to as a full state) An empty dungage in which the item A is not stored or a full dunnage will be placed. At this time, all the items A supported by the lower dungage item supporting member 3 of the dunnage are placed. The vertical ribs 4a of all the upper article supporting members 4 of Dunedge located above are fitted into the upper part of the vertical through hole a3 at once.

Some of the cylindrical connecting portions 4b extend further downward, and a cylindrical fitting member 11 is formed by the portion extending downward. In the present embodiment, the cylindrical connecting portion 4b corresponding to the article lower storage recess 1A located at the center of the rectangular region R1 of the plate-like substrate 2 and the article lower storage recess 1B disposed on both sides of the recess 10 described above. An example is shown in which the fitting member 11 is formed in the cylindrical connecting portion 4b corresponding to the article lower storage recess 1E.

When empty dunes that do not store articles are stacked, as shown in FIG. 8, in the hole 3c1 of the annular top 3c of the article lower support member 3 of the lower dunnage, as shown in FIG. The upper dunnage fitting member 11 is configured to be fitted, and when empty dunnages are stacked, horizontal movement with respect to the dunnage located below the upper dunnage is restricted. Therefore, a large number of empty dunnages can be stacked in a stable state.

In the above-described embodiment, an article A composed of a disk-like lower flange portion a1 and a cylindrical portion a2 standing from the center portion of the lower flange portion a1 is shown as an example. However, it is not limited to such an article A. For example, the through hole lower part and the through hole upper part of the vertical through hole a3 formed in the article A described above can have different inner diameters. In this case, the outer diameter of the cylindrical peripheral wall 3a constituting the article lower support member 3 fitted to the lower part of the vertical hole a3 of the article A and the upper part of the vertical hole a3 of the article A The diameter of the imaginary circle formed by the outer end surface 4a2 of the vertical rib 4a of the article upper support member 4 fitted to the upper part of the article is different according to the through hole lower part and the through hole upper part of the vertical through hole a3. Become.

As described above, the inner diameters of the lower and upper holes of the vertical through hole a3 formed in the article A are different, and the lower and upper holes of the vertical hole a3 formed in the article A are the same. In the case where the diameter of the virtual circle formed by the outer end surface 4a2 of the vertical rib 4a of the article upper support member 4 is different from the inner diameter of the article upper support member 4, for the reason described above, it is stored in the dunnage located below.
