BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a cushioning material fixing structure in a packing box according to the present invention. FIG. The packing box in the present invention is made of cardboard paper. One embodiment of the cushioning material fixing structure in the packing box according to claim 1 or 2 is shown in FIGS. FIG.
FIG. 3 is a diagram showing the packing box 1 before assembling the bottom part upside down. The bottom of the packing box 1 is formed with an outer flap 1a and an inner flap 1b.
The two cuts 1c are made at predetermined intervals in the center of the tip side of the cushioning member fixing member 1 by the two cuts 1c.
d is formed. In this configuration, as shown in FIG. 2, after arranging a two-piece cushioning material 2 (shown by a dashed line) at the bottom in the packing box 1, the cushioning material fixing member 1d is folded at its base end (shown by a dashed line). Fold it up and stand upright. As a result, as shown in FIG.
The side end of d comes into pressure contact with the cushioning material 2 (contact so as not to move easily by mutual frictional force), and the cushioning material 2 is fixed so as not to move.

The cushioning member fixing member 1d has to press the cushioning member 2 appropriately when it is turned upright. In order to achieve this purpose, as shown in FIG. Notch 1c so that it is slightly wider
Is desirably formed in a tapered shape. FIG. 4 shows the cushioning material 2
Indicates the case of four pieces. Similarly, by folding back the cushioning member fixing member 1d, each cushioning member 2 'can be fixed. The cushioning member fixing member 1d of the embodiment is
Although a cut is formed in the inner flap 1b, another member can be attached to the bottom to form a similar cushioning member fixing member.

One embodiment of the cushioning material fixing structure according to the third or fourth aspect is shown in FIGS. FIG. 5 is a perspective view of the packing box 1 with the bottom part facing down as usual, and FIG. 6 is a side view of the packing box 1 with two pieces of cushioning material 2 (broken line part) arranged at the bottom part. . As shown in the drawing, the side plate 1e of the packing box 1 is provided with two buffer material fixing members 1g formed by cutting or embossing a predetermined position of the side plate 1e. The buffer material fixing member 1g is located below the upper surface of the buffer material 2. On the other hand, as shown in FIG. 7, a concave portion 2a is provided in a portion of the cushioning material 2 facing each cushioning material fixing member 1g. In this configuration, as shown in FIGS. 7 and 8, when the two-piece cushioning material 2 is disposed at the bottom in the packaging box 1, the cushioning material fixing member 1 g is folded in the direction of the arrow (inward of the packaging box 1). Then, it is pushed into the concave portion 2a of the cushioning material 2. As a result, both side edges of the cushioning member fixing member 1g are pressed against the inner surface of the concave portion 2a of the cushioning member 2, and the cushioning member 2 is fixed so as not to move by the frictional force. When the buffer material fixing member 1g is folded into the concave portion 2a of the buffer material 2, the distal end portion thereof becomes slightly wider as shown in FIG. 9 in order to press the buffer material 2 appropriately. , Cut 1f
Is desirably formed in a tapered shape. 10 and 11
