You may make it apply | coat the peeling material 43 to the surface.

When the cushioning material 10 is manufactured and then conveyed to the user, the corrugated cardboard and the cardboard formed in the developed shape shown in FIG. 4 are assembled to form the box body 17, and the box body 17 is rolled therein. The cushioning material 10 wound in a shape is stored.
By storing the cushioning material 10 in the box body 17 in this manner, it is possible to stack the cushioning material 10 easily.

When the cushioning material 10 is used, the inner top wall portion 21 is bent as shown in FIG. 1 to form the support shelf portion 32 which is continuous with the feeding port 36. In this state, as shown in FIG. 6, the cushioning material 10 is cut for each predetermined length, and the article is wrapped.

At that time, the worker stands up toward one of the left and right side walls. The box 17 is a front wall,
The rear wall and the left and right side walls are four side walls, and the side wall having the feeding port 36 is the front side of the box body 17,
Either side may be the front side in relation to the position of the operator.

As described above, in the container for storing and feeding the cushioning material according to the illustrated embodiment, when the cushioning material 10 wound in a roll in the box 17 is packed and transported, Since the inner top wall portion 21 overlaps the inner side of the outer top wall 15 and the feeding port 36 is not formed, dust and the like are prevented from entering inside during transportation. In particular, in the case of the cushioning material 10 made of a resin sheet, dust or the like tends to adhere due to the generation of static electricity, but since it is in a substantially sealed state during transportation, such adhesion of dust is prevented. It

On the other hand, when the cushioning material 10 is cut into predetermined lengths, the inner ceiling wall portion 21 folded inside during transportation is bent outward to form the feeding port 36 and the inner ceiling. With the support shelf 32 and the fastening portion 31 that form the wall portion 21, the support shelf 32 supported by the fastening portion 31 can be formed on the front wall 15 so as to protrude from the front wall 15 at the portion of the front wall 15.

Therefore, by using the support shelf portion 32 as a pedestal, the work of feeding out the cushioning material 10 by a desired length and cutting it can be performed extremely easily. Moreover, the tip of the cushioning material 10 does not return to the inside of the box after cutting, and the next cutting operation can be easily performed subsequently.

When the cutting operation is interrupted for a relatively long time, the inner ceiling wall portion 21 is returned to the inside of the ceiling wall 15 so that the feeding port 36 is closed and the cushioning material 10 is placed in the box body 17. It is in a sealed state, preventing dust from entering the inside.

Although the invention made by the inventor has been specifically described based on the embodiment, the invention is not limited to the embodiment and can be variously modified without departing from the gist of the invention. Needless to say,

For example, the bottom wall 16 of the box body 17 may have any shape or structure, and the adhesive portion 26 may be the front wall 1.
1, the back wall 12 or the right wall 14 may be integrally provided. Further, in the illustrated case, the inner wall portions 22 and 2 are formed on the rear wall 12 and the right wall 14, respectively.
However, the inner top wall portion 21 may be provided only on the front wall 11.
