[0002]

2. Description of the Related Art For example, in transportation and storage of eggs packed for business use, a method of loading eggs on a fixed rack is employed. However, since the size of the rack does not conform to the size of the pack, there is a possibility that the pack may be damaged or the egg may break due to a swing deviation during transportation, resulting in instability in transportation. In addition, the height of the rack is low, the height of the transport vehicle cannot be used effectively, the transport efficiency is low, and it is not possible to fold it when collecting empty racks. ing.

[0003]

In view of the above situation, the inventor has found that in order to eliminate the instability during transportation and to improve the transportation efficiency, the container should be a tall container that is efficient during transportation and storage. And, when not in use, I investigated the structure that can be folded, and the frame on the wife side of the container can be folded,
Moreover, the present invention has been completed based on the idea of having a structure in which it can be pulled out in two steps.

[Operation] Next, the case of using it for packed eggs will be described. The container is folded as described above, the gable frames 3 and 3 are erected, and the egg packs are loaded on the bottom plate. Eggs are packed in upper and lower packs of a plastic egg receiver in which, for example, six eggs are arranged in one row and six rows are arranged alternately, and the upper egg pack is inserted into the space formed between the lower egg receivers. , Stacking, for example, 6 steps. A vertical partition plate is placed between the stacked packs on the left and right to prevent the packs from swinging. Next, an empty pack is placed with the edge plane facing up to form a horizontal plane on which the edge planes of the pack are laid, and a horizontal plate having the inner size of the container is placed on the horizontal plane. Pack the egg pack on this plate as described above. The pack load from above is received by the horizontal plate supported by the vertical partition plate to support the load and prevent the load from being concentrated locally. After loading, attach the front and rear upper and lower frames for transportation and storage. After loading and unloading the container, release the latch fittings, remove the upper and lower frames on the front and rear, retract the drawer gable frame, remove the fixing pin of the folding gable frame from the fitting groove of the base material, and use the guide pin as a fulcrum. It can be easily folded into a small volume by folding it inside and stacking the upper and lower side frames, vertical partition plates, and horizontal plates. Although the case of the egg pack has been described above, it can be similarly used for transportation and storage although it is relatively lightweight and bulky and easily damaged.
