Further, the pulp mold member 3 having the fitting portion 31 fitted into the through hole 27 of the overlapping portion 25 holds the base member 2 in a three-dimensional shape. The pulp mold member 3 comes into contact with the packaged product 9 in the packaging box 8.

In the following description, the surface of the base member 2 facing the packaged product 9 is referred to as an inner surface 2a, and the surface of the base member 2 facing the inner surface of the packaging box 8 is referred to as an outer surface 2b.

The fourth plate portion 24 overlaps a part of the inner surface 2a of the third plate portion 23. In other words, a part of the third plate portion 23 overlaps the outer surface 2b of the fourth plate portion 24.

The edge of the opening 26 in the first plate portion 21, the second plate portion 22, the single portion 250 of the third plate portion 23, and the fourth plate portion 24 has a cut-up piece 260.

In the single portion 250 of the first plate portion 21, the second plate portion 22, and the third plate portion 23, the fitting portion 31 of the pulp mold member 3 is inserted into the opening 26 from the outer surface 2b side toward the inner surface 2a side. Similarly, in the overlapping portion 25, the fitting portion 31 of the pulp mold member 3 is inserted into the opening 26 from the outer surface 2b side toward the inner surface 2a side.

The cut-up piece 260 of the single portion 250 of the first plate portion 21, the second plate portion 22, and the third plate portion 23 comes into contact with the fitting portion 31 inserted into the opening 26 from the outer surface 2b side toward the inner surface 2a side. As a result, it is cut up toward the inner surface 2a side and comes into contact with the side surface of the fitting portion 31.

Similarly, the cut-up piece 260 of the fourth plate portion 24 is also cut up to the inner surface 2a side by abutting the fitting portion 31 inserted into the through hole 27 from the outer surface 2b side toward the inner surface 2a side. It touches the side surface of 31.

The cut-up piece 260 of the fourth plate portion 24 is an edge portion of the through hole 27 in the portion forming the inner surface 2a of the overlapping portion 25. The inner surface 2a of the superimposing portion 25 is an example of the first surface of the superimposing portion 25, and the outer surface 2b of the superimposing portion 25 is an example of the second surface of the superimposing portion 25 on the opposite side to the first surface.

By contacting the cut-up piece 260 with the side surface of the fitting portion 31, the fitting portion 31 is prevented from coming out from the opening 26 or the through hole 27 to the outer surface 2b side. Further, the flange portion 32 prevents the fitting portion 31 from coming out from the opening 26 or the through hole 27 to the inner surface 2a side.

Further, the recess 310 in the fitting portion 31 fitted in the through hole 27 of the overlapping portion 25 of the lower cushioning body 1A also serves as a handle used when the packing body 9 is taken out from the packing box 8 together with the lower cushioning body 1A.

The cushioning body 1 is made of a paper material including corrugated cardboard 100. As a result, the packing box 8 and the cushioning body 1 can be recycled together.

Further, in the shock absorber 1, the pulp mold member 3 fitted in the overlapping portion 25 of the base member 2 and the through hole 27 of the overlapping portion 25 forms a connecting portion for maintaining the base member 2 in a three-dimensional shape. There is.

The pulp mold member 3 can be configured as a member having higher strength than the corrugated cardboard 100. Therefore, the overlapping portion 25 of the base member 2 and the pulp mold member 3 can connect the third plate portion 23 and the fourth plate portion 24 of the base member 2 with high connection strength. Moreover, the buffer body 1 can be assembled by a simple operation of fitting the fitting portion 31 of the pulp mold member 3 into the through hole 27 of the overlapping portion 25.

It is also conceivable that in the buffer body 1, the plate portions that are overlapped in three or more layers form the overlapping portion 25. In this case, the fitting portion 31 of the pulp mold member 3 is fitted into the through hole 27 formed in the overlapping portion 25 that overlaps three or more.
