<Means for Solving Problems> The problem solving means according to the present invention is such that a trapezoidal hole 12 is formed on the bottom surface of the packaging box 4 as shown in FIGS. The missing packaging box material 13 is folded back inward at the short side portion 12a, and the projecting body 2b fitted into the hole 12 and the packaging box material 13 are fitted on the bottom surface of the cushioning material 2 for packing the article 1 to be packaged. A recess 2c to be engaged is formed, and a large number of small anti-slip projections 3 are integrally formed on the exposed surface 2a of the projecting body 2b from the hole 12.

<Operation> In the above problem solving means, when the object to be packaged 1 is packed,
The protrusion 2b of the cushioning material 2 is fitted into the trapezoidal hole 12 of the packaging box 4 and exposed to the outside, and the small protrusion 3 formed on the outer exposed surface 2a of the cushioning material 2 projects from the bottom surface of the packaging box 4.

Therefore, when the packaging boxes 4 are stacked high, the small protrusions 3 exposed from the packaging boxes 4 are compressed by the weight of the objects to be packaged 1 and the friction becomes large, and the slippage between the packaging boxes is prevented.

Further, the concave portion 2c of the cushioning material 2 and the notched packaging box material 13 of the packaging box 4 are engaged with each other, and the cushioning material 2 is not displaced due to the presence of two opposed trapezoidal engaging portions. In particular, when the side surface of the cushioning material 2 is exposed to the outside of the packaging box 4, the cushioning material 2 is not displaced even if a direct impact is applied, which is effective in preventing the packaged object from falling off.
