The upper ends of the upper pieces that remain on both sides of the elongated opening are detachably or foldably attached to the rectangular upper frame, and the lower pieces that remain on both sides of the elongated opening are formed by cutting across the side plates. The lower end is foldably pivoted to the rectangular lower plate, the upper piece and the lower piece are foldably and pivotally connected inward, and the lid that closes the elongated opening is pivotally pivoted in and out. Therefore, by rotating the lid and retracting it, and then folding the upper and lower pieces in half, the container can be folded into a compact size while forming a long opening in the long side plate. By releasing the locking means of the lid that closes the elongated opening and opening and rotating the lid, an elongated opening can be formed on the elongated side plate side, and even when containers filled with contents are stacked, the elongated opening can be formed. The long opening allows the contents to be inspected, confirmed, taken out, and refilled as desired, and this purpose can be fully achieved.In addition, the lid is divided into upper and lower halves, and these halves can be folded freely. Even if the height of the elongated opening is increased and the height of the lid that closes this elongated opening is increased, the lid is divided into upper and lower parts, and the divided parts can be folded together. Therefore, even if the width of the short side of the folding container is small, folding the tall lid toward the inside of the container may impair the folding function of the folding container. The advantage is that there is no
