In the packaging device of Patent Document 1, the pressing piece presses one side of the cushioning material that protects the product packed in the box, using the restoring force of the cut and raised pressing piece. In addition, the packing device is configured such that the opposite side of the cushioning material pressed by the pressing piece is pressed against the side surface of the exterior cardboard, so that the cushioning material is sandwiched between the holding piece and the side surface, The position of is held.

Japanese Utility Model Publication No. 55-56154

In the packaging device of Patent Document 1, when the cushioning material is sandwiched between the presser piece and the side surface and the position of the cushioning material is maintained, there is a gap between the presser piece and the cushioning material. Only the tip of the piece is in contact with the cushioning material. Therefore, the conventional packing device has a small frictional resistance between the presser piece and the cushioning material when the cushioning material moves in the direction in which the presser piece is holding the cushioning material in the state where the cushioning material is sandwiched. The material becomes easy to move. As a result, in the conventional packing device, there is a concern that the buffer material is displaced due to the movement of the buffer material, and the buffer material is detached from the presser piece.

This invention is for solving the above problems, and is to provide a packaging device that can hold the position of the cushioning material on the exterior corrugated cardboard located at the bottom and does not remove the cushioning material from the presser piece.

A packing device according to the present invention includes a bottom cardboard material including one or more bottom cushioning materials on which a bottom portion of a packaged body is placed and a flat bottom plate portion on which one or more bottom cushioning materials are placed.
