A bendable movable piece is provided on the side of the inner plate, and a contact piece with a locking edge such as a protrusion or notch is provided on the upper side of the inner plate. The contact piece is attached to the side plate, and then the contact piece is bent and the back side is overlapped and attached to the inner plate, so that when each side plate is erected during use, the contact piece is locked by the locking edge. The movable piece is clamped and fixed between the contact piece and the inner plate, ensuring the uprightness of the three sides of the side plate, and the rest of the structure is necessary for a carry deco case.

The specific structure of this invention is, first, a front plate and a rear plate are provided on the front and rear sides of a rectangular bottom plate, each having a cover plate and protrusions at appropriate places on both sides, and a handle opening. Handle plates with cutouts forming the bottom plate are sequentially arranged in a bendable manner, and a left side plate and a right side plate are provided on both sides of the bottom plate so as to be bendable, and the left side plate,
A bendable piece with a tongue formed by a notch is provided on the upper side of the right side plate, and an insertion hole that fits the front protruding piece is bored in this tongue piece, and on both sides of the rear side plate. Each inner plate is provided with a bendable inner plate, and each inner plate is provided with a movable piece that can be bent freely on the side of the left side plate and right side plate, respectively, and a protrusion or notch is provided on the upper side of each inner plate. A bendable abutting piece having a locking edge such as the above is provided, each inner plate is attached to the rear side plate, and the abutting piece is further bent and a part of the back side is overlapped and attached on the inner plate. When the rear side plate, left side plate, and right side plate are erected, the abutment piece is locked by the locking edge and the movable piece is held between the abutment piece and the inside plate. .

(Function) When the rear side plate and the left and right side plates are erected, the movable pieces connected to the left and right side plates are held between the abutting piece partially attached to the inner side plate and the inner side plate. ,
