とを特徴とするものである。<Means for Solving the Problems> A method of compressing and storing an object to be compressed in a container according to the present invention is as follows: (a) after storing the object to be compressed in a container, a size slightly larger than the inner diameter of the container is placed thereon. A flexible first detent plate made of a thin metal plate is placed, and the object to be compressed in the container is moved by the compression plate which is interlocked with the compressor and has a size slightly smaller than the inner diameter of the container. Compressing together with the detent plate toward the bottom of the container, and then raising the compression plate, (b) the first detent plate of the internal space of the container obtained by the compression in the step (a) above. After accommodating a new object to be compressed, a second detent plate is placed thereon, and the new object is compressed by the compression plate together with the second detent plate into the container. Compressing in the bottom direction and then raising the compression plate, and (c) repeating the above step (b) as many times as necessary. And it is characterized in that consists extent.

Therefore, it bends while pressing the inner wall surface of the container, and in this state, it stays at the position where it is pushed down by the compressor. Therefore, the compressed object compressed below the detent plate is prevented from being restored in volume by the detent plate.

圧縮物の体積の復元を阻止する。In such a state, proceed to the next step (b), and a new object to be compressed is stored on the detent plate and the second object is placed thereon.
When compressed together with the detent plate of the second detent plate, the second detent plate stays in the depressed position in the same bent state as the first detent plate, and a new compressed object compressed under the second detent plate is retained. Prevent the restoration of the volume of things.
