Description

[Detailed Description of the Invention] Industrial Application Field The present invention mainly relates to a packaging cushion used for packaging articles having a cube, a rectangular parallelepiped, or a similar shape.

2. Description of the Related Art Generally, when an article is packaged in an outer box such as a cardboard box, a buffer is interposed between the article to be packaged and the outer box to protect the article from external impact. In particular, when packaging a cube, rectangular parallelepiped, or similar-shaped item in an outer box, a cushioning material is inserted between the four corners of the outer box and the corner of the packaged item, so that the product and the outer box are packaged. A void is maintained on the inner surface of the packaging material, and the entire packaged item is protected by the cushioning material alone.

Problems to be Solved by the Invention However, the conventional cushioning bodies are placed at the four corners of the outer box, or simply applied or fitted to each corner of the packaged article. When storing items in the outer box or when carrying or transporting them after packaging, the cushioning material may shift or easily come off from the item, causing considerable problems in storing and protecting the item. is the actual situation.

Means for solving the problems Therefore, the present invention was constructed as follows. In other words, it is a packaging cushion made of a cushioning member having a substantially triangular pyramid shape and a hollow double-wall structure that is placed over the corner of the packaged article and comes into contact with each side of the corner of the packaged article. A locking protrusion with a T-shaped vertical cross section is integrally formed on the outer wall by a parallel, planar plate and a plate connected to the parallel plate and perpendicular to the outer wall surface.

Function Since the present invention is constructed as described above, the cushioning member placed over the corner of the article can be fixed to the locking protrusion by forming a hole in a plate such as a cardboard plate that is placed against the upper and lower surfaces of the article to be packaged. Since it can be easily inserted and fixed, it is possible to prevent it from shifting or falling off, and to reliably protect the packaged goods. It has the feature that it can be reused because it can be easily removed by bending the part of the plate that is perpendicular to the outer wall surface.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

In the drawings, reference numeral 1 denotes a buffer member made of a hollow double-walled plastic structure.
is formed into a shape that is placed over a corner of an article 2 such as a rectangular parallelepiped and abuts three surfaces 3, 4, and 5 of the corner, that is, a substantially triangular pyramid shape. Concave grooves 10 are formed in the inner wall of the buffer member 1 at locations corresponding to the apex 6 of the packaged article 2 and its respective ridgelines 7, 8, and 9. Further, the outer wall top portion 11 of the buffer member 1 is formed to be rounded, and each of the skirt portions 12, 13, and 14 of the buffer member 1 is formed in a shape that opens outward in an inclined shape. A locking protrusion 15 is integrally formed on one surface of the outer wall of the buffer member 1.
Reference numeral 5 has a T-shaped longitudinal section formed by a planar plate 15a parallel to the outer wall surface and a plate 15b connected thereto and perpendicular to the outer wall surface. The locking protrusions 15 fit into holes 17 made at the four corners of a plate 16 such as a cardboard board, and the plate 16 is fitted into the cushioning member 1.
This is for locking 6. The plate body 16 is a top plate or a bottom plate that comes into contact with the upper and lower surfaces of the packaged article 2 . 18 is an outer box, such as a cardboard box.

The buffer member 1 is molded by a thermoplastic blow molding method, and the thermoplastic may be made of polyethylene, polyamide, vinyl chloride, or the like.

When storing the article 2 in the outer box 18 and packaging it, first, a cushioning member 1 is attached to each corner of the article 2 to be packaged.
The inner wall surface is brought into close contact with the three corner surfaces 3, 4, and 5 of the article 2 to be packaged. Next, the plate 16 that will become the top plate or the bottom plate is placed along the top or bottom surface of the article 2. By bending the plate 16b perpendicular to the outer wall surface of the locking protrusion 15 of the buffer member 1 into each hole 17, 17..., the planar plate 16a parallel to the outer wall surface is inserted and fixed. Then, the article to be packaged 2 is placed in the outer box 18.
If the outer box 18 is closed, the packaged article 2
is packaged with its corners immovably supported on the inner surface of the outer box 18 via the buffer member 1.

Cushioning member 1 placed over each corner of article 2 as described above
are secured to the upper and lower surfaces of the article 2 by the plate members 16, so that the buffer member 1 may be misaligned when the article 2 is stored in the outer box 18.
The work of storing and packaging the article 2 in the outer box 18 can be easily performed without falling off. Further, even after being packaged in the outer box 18, the buffer member 1 will not be displaced in the same way.

Note that the buffer member 1 has grooves 10 formed on its inner wall at locations corresponding to the apexes 6 and ridge lines 7, 8, and 9 of each corner of the article to be packaged 2, so that each of the articles to be packaged 2 is Corner apex 6 and twill lines 7, 8, 9
Since the cushioning member 1 does not come into contact with these parts, there is no risk that these parts will be damaged by being rubbed by the cushioning member 1, and the packaged article 2 is reliably protected.

Effects of the invention Since the present invention is constructed as described above, the cushioning member placed on the corner of the article can be locked by forming holes in a plate such as a cardboard plate that is placed against the upper and lower surfaces of the article to be packaged. It has the effect of being able to fit the protrusion and fix it easily, thereby preventing it from shifting or falling off, and reliably protecting the packaged goods, as well as being able to detach from the board such as a cardboard board. This can be easily removed by bending the portion of the plate perpendicular to the outer wall surface of the locking protrusion, which has the effect of allowing reuse.
