Description

  The present invention relates to a cushioning material for packing which is inserted into an outer box and regulates the movement of an article when packaging an article having a curved surface on the outer periphery, such as a circular lighting fixture.

For example, in the following Patent Document 1, as shown in FIG. 5, as a corrugated cardboard cushioning material used for packing a cylindrical rice cooker W, end plates 52 are continuously provided on each side of a rectangular bottom plate 51. When the plate 52 is erected and inserted into the bottom of the outer box 53, the end plate 52 is brought into contact with the outer periphery of the rice cooker W so that the movement of the rice cooker W is regulated.

  However, with the cushioning material as described above, the phenomenon that the article jumps due to an impact during transportation cannot be prevented. To prevent this jumping phenomenon, a cushioning material that holds the article from above is inserted into the outer box separately. There is a need to.

  Therefore, an object of the present invention is to provide a packing cushioning material that can easily prevent a jumping phenomenon of an article stored in an outer box and protect the article.

  In order to solve the above-described problems, in the present invention, two adjacent sides of a bottom plate on which an article is placed form an obtuse angle, and an end plate is connected to one side and a corner plate is connected to the other side. A connecting part that connects the base end of the plate is provided, and an oblique fold line inclined toward the corner plate is inserted at the boundary between the end plate and the connecting part starting from the corner of the bottom plate, and a valley fold line is provided on both sides of the end plate. When inserted into the outer box, the end plate bends inwardly along the oblique and valley fold lines, the article is held by the end plate, and the corner plate comes into contact with two adjacent side plates of the outer box The outer box was reinforced by being inclined to the outside and supported by the corner plate.

  In addition, a swing piece is formed in the corner plate by making two cut lines from the bottom plate side, and a fitting hole is formed on the tip side of the swing piece. Is pushed by the outer periphery of the article and swings, and when the outer periphery of the article fits into the fitting hole, the swing piece is restored, and the tip of the swing piece and the outer periphery of the article are engaged. However, the article may be held.

  As described above, in this cushioning material, when the article is inserted into the outer box, the outer peripheral portion of the article is pressed by the end plate inclined inward only by placing the article on the bottom plate, so that the jumping phenomenon of the article in the outer box is prevented. Further, since the corner plate functions as a support column that reinforces the side plate of the outer box, the pressure resistance is improved and the article is reliably protected.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  This cushioning material is used for packing circular lighting fixtures, and is formed from a cardboard blank as shown in FIG. In this blank, the bottom plate 1 is an irregular octagon, and among the sides forming the periphery thereof, the end plate 2 is connected to the short side every 90 °, and the long side forming an obtuse angle of 135 ° with respect to the short side The corner plate 3 is continuously provided.

  The base ends of the end plate 2 and the corner plate 3 are connected via a connecting portion 4, and the boundary between the end plate 2 and the connecting portion 4 is inclined toward the corner plate 3 with the corner of the bottom plate 1 as a starting point. The diagonal fold line 5 is inserted, and the both sides of the end plate 2 are provided with valley fold lines 6 reaching the leading edge. In addition, a diagonal line 7 extending from the corner of the bottom plate 1 to the cut at the side edge of the corner 3 is provided at the boundary between the corner plate 3 and the connecting portion 4.

  Further, the corner plate 3 is formed with a swing piece 8 between two cut lines inserted from the bottom plate 1 side, and a fitting hole 9 is formed along the boundary with the bottom plate 1 at the tip side thereof. A protrusion 10 is provided at the tip of the swing piece 8 toward the fitting hole 9. In addition, the boundary between the bottom plate 1 and the end plate 2 is notched on both sides of the central connecting portion.

  When packing a circular lighting fixture using the blank cushioning material as described above, the flap 13 extending from the upper edge of the side plate 12 is opened in the outer box 11 as shown in FIG. The surface is opened, and the cushioning material is placed on the flap 13 of the outer box 11. At this time, the direction of the end plate 2 of the buffer material and the direction of the side plate 12 of the outer box 11 are matched.

  Next, as shown in FIG. 3, when the luminaire S is placed on the bottom plate 1, the bottom plate 1 descends into the outer box 11 due to the weight of the luminaire S, and accordingly, the connecting portion along the oblique line 7. 4 stands up, the end plate 2 bends inward along the oblique fold line 5 and the valley fold line 6, and the corner plate 3 contacts the two side plates 12 adjacent to each other in the outer box 11. Stand up leaning toward.

  When the lighting fixture S is packed in this way, the outer peripheral portion of the lighting fixture S is pressed by the end plate 2 inclined inward, so that the jumping phenomenon of the lighting fixture S inside the outer box 11 is prevented, and the corner plate 3 Functions as a strut that reinforces the side plate 12 of the outer box 11, so that the pressure resistance is improved, and the lighting fixture S is reliably protected from external impact and load.

  In addition, when the packing is performed, as shown in FIG. 4, when the swing piece 8 is pushed by the outer peripheral portion of the lighting fixture S and the outer peripheral portion of the lighting fixture S fits into the fitting hole 9, Since the moving piece 8 is restored and the protrusion 10 at the tip of the swing piece 8 is engaged with the flange on the outer peripheral portion of the lighting fixture S, the lighting fixture S is integrally held by the cushioning material. S does not rub and move.

  When the article to be packed is weak against impact from below, the peripheral edge of the bottom plate 1 is cut and leg pieces are continuously provided on the corner plate 3. If the leg piece protrudes downward from 1, a buffer space can be provided between the bottom plate 1 of the buffer material and the bottom wall of the outer box 11.
