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 transporting or transporting them after packaging, the cushioning material tends to shift or come off from the item, causing considerable problems in storing and protecting the item. This is the actual situation.

Means for Solving the Problems In order to solve the above problems, the present invention was constructed as follows. In other words, it consists of a hollow double-walled cushioning member that is shaped to fit over the corner of the packaged article and come into contact with each surface thereof, and a locking piece is attached to the cushioning member via a bendable hinge. One surface of the outer wall of the buffer member that is integrally connected and has this hinge forms a locking protrusion, and
The locking piece is formed with a through hole for engaging with the locking protrusion, so that the locking piece can be freely engaged and detached from an entire surface of the outer wall of the buffer member having a hinge.

Function Since the present invention is configured as described above, the locking piece is inserted into the hole formed in the top plate and the bottom plate, and the locking piece is folded back, and the locking protrusion is locked and fixed in the locking hole. By fixing the buffer member to the top plate and the bottom plate, the buffer member can be prevented from shifting or falling off, and the packaged articles can be reliably protected.

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 top portion 11 of the outer wall of the buffer member 1 is formed to be rounded, and the hem portions 13 and 14 of the hem portions 12, 13, and 14 of the buffer member 1 are formed in a shape that opens outward at an angle. has been done. A locking piece 15 is integrally connected to one side hem 12 of the buffer member 1 via a bendable hinge 16. This locking piece 15 has substantially the same shape as one surface of the buffer member 1. A locking projection 17 is formed on one surface of the outer wall of the buffer member 1, and an engagement hole 18 for the locking projection 17 is formed in the locking piece 15.
The locking piece 15 can be freely connected to and removed from the entire outer wall of the buffer member 1. Reference numeral 19 is a plate such as a cardboard board, and the four corners of this plate 19 have holes 20 through which the locking pieces 15 are inserted and holes 2 through which the locking protrusions 17 are inserted.
2 is open. The plate body 19 is a top plate or a bottom plate that comes into contact with the upper and lower surfaces of the packaged article 2 . 21 is an outer box, such as a cardboard box.

In addition, the buffer member 1, the locking piece 15, and the hinge 1
6 is molded by a thermoplastic blow molding method, and polyethylene, polyamide, vinyl chloride, etc. are used as the thermoplastic plastic.

When storing the article 2 in the outer box 21 and packaging it, first, each corner of the article 2 to be packaged is covered with a cushioning member 1, and the inner wall surface of the cushioning member 1 is placed on each corner of the article 2 to be packaged. 4 and 5, and then place the plate 19 that will become the top or bottom plate along the top or bottom surface of the article 2, and insert the locking pieces 15 into each hole 20 so that the hinge 16 locks into the hole 20. make it match. Then, the locking piece 15 is brought down over the outer wall of the buffer member 1, and its engagement hole 18 is engaged with the locking protrusion 17 inserted into the hole 22, thereby locking the buffer member 1 and the plate 19, and then 2 is stored in the outer box 21 and the outer box 21 is closed, the packaged article 2 is packaged with its corner portion immovably supported on the inner surface of the outer box 21 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 plates 19, so that the buffer member 1 may become misaligned when the article 2 is stored in the outer box 21.
The work of storing and packaging the article 2 in the outer box 21 can be easily performed without falling off. Furthermore, even after being packaged in the outer box 21, 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, by forming holes in the plates serving as the top plate and the bottom plate, the buffer member can be easily and securely fixed to the plates. As a result, it is possible to prevent the package from shifting or falling off, and it is also possible to reliably protect the packaged article.
