Description

[Brief explanation of the drawing]

Fig. 1 is a developed view showing one embodiment of the cushioning material for packaging ventilation fans according to this invention, Fig. 2 is a perspective view of the assembled state, Fig. 3 is a cross-sectional view showing the same packaging form, and Figs. 4 and 5. The figures are a developed view and a perspective view of the assembled state of ventilation fan packaging cushioning materials of other embodiments, respectively.
FIG. 6 and FIG. 7 are a developed view and an assembled perspective view, respectively, showing a cushioning material for packaging a ventilation fan according to still another embodiment. In the figure, 1 is a paperboard material, 2 is a slit (parallel slit), 3 is a first inside fold line, 4 is a second inside fold line, 5 is a first outside fold line, 6 is a second outside fold line, 7 is a bottom plate, and 8 is a Outer plate, 9 is inner plate, 10
11 is a top plate, 11 is a reinforced buffer portion, 12 is a discontinuous slit, 13 is a flap, 14 is a broken line, 15 is a side plate portion, and 16 is a slit. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Scope of Claim for Utility Model Registration] (1) Two slits are formed on each side of the paperboard material at a constant interval on both sides of the center line, and two slits are formed on each side of the paper board with the center line as a boundary. A first inner fold line is provided between each other parallel to the center line and on the side of the center line, and a second inner fold line is provided outside of the first inner fold line parallel to the first inner fold line, and the center line of the slit is A first outer fold line is formed parallel to the center line from the side edge to the periphery, and a second outer fold line is formed parallel to the first outer fold line from the outer side of each of the slits to the periphery. By bending the plate material at right angles on the first outer fold line and the first inner fold line to form a bottom plate, outer plate, and inner plate, and bending the plate material at right angles to the outside on the second outer fold line and the second inner fold line. In the cushioning material for ventilation fan packaging forming the upper plate, the reinforcing cushioning part including a flap that at least partially overlaps with the upper plate and closes the opening created by the slit between the inner plate and the outer plate is provided as above. A cushioning material for packaging a ventilation fan, characterized in that it is integrally formed on both edges on the center line of a paperboard material or on both edges in a direction perpendicular to the center line. (2) Two parallel slits are formed on each side of the paper board at a constant interval, and the ends on the center line side of each of these two parallel slits are formed with slits parallel to the center line. A first inner fold line is provided between each of the two parallel slits connected to each other with the center line as a boundary, parallel to the center line, and on the center line side, and the first inner fold line is provided on the outer side of the first inner fold line. A second inner fold line is provided in parallel with each of the first outer fold lines, and a first outer fold line is formed parallel to the center line from the end of the parallel slit on the center line side to the periphery, and each of the first outer fold lines is parallel to the first outer fold line. A second outer fold line is formed from the outer side of the slit to the periphery, the paper board is divided along the center line, and the paper board is bent at right angles along the first outer fold line and the first inner fold line to form a bottom plate and an outer plate. and forming an inner plate;
In the cushioning material for ventilation fan packaging of a paired configuration, which forms an upper plate by bending at right angles on the second outer fold line and the second inner fold line, the cushioning material overlaps the upper plate and is formed between the inner plate and the outer plate. A cushioning material for packaging a ventilation fan, characterized in that reinforcing cushioning parts including flaps that close openings formed by the parallel slits are integrally formed on both edges of the paper board in a direction perpendicular to the center line.
