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 is a packaging cushion made of a hollow double-walled cushioning member that is formed into a substantially triangular pyramid shape and has an inner wall that covers the corners of the article to be packaged and comes into contact with each side thereof, and the top of the outer wall of the cushioning member is one end of the presser plate is integrally connected via a bendable hinge, a latch is formed on the open end side of the presser plate via the bendable hinge, and a latch receiving portion is formed at the hem of the buffer member; By locking the latch of the presser plate to the latch receiving portion of the buffer member, the presser plate is configured to be freely engageable and detachable from the buffer member.

Function Since the present invention is constructed as described above, by sandwiching the plate between the buffer member and the holding plate, the latch described above is inserted into the insertion hole of the plate and the tip of this latch is inserted into the buffer member. This prevents the buffer member from shifting by locking and fixing it to the
Furthermore, since the holding plate uses two hinges to pinch the plate, it is extremely stable.
It will not come off easily due to impact.

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.
The shape is such that it is placed over the corner of the article 2, such as a rectangular parallelepiped, and abuts the three surfaces 3, 4, and 5 of that part, that is, it is formed by integrally connecting three flat bodies. 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,
Of the respective hem portions 12, 13, and 14 of the buffer member 1, the hem portions 13 and 14 are formed in a shape that opens outward in an inclined manner. A retainer plate 1 is attached to one ridgeline portion of the buffer member 1.
5 are integrally connected via a bendable hinge 16. This holding plate 15 has substantially the same shape as one surface of the buffer member 1, and a latch 17 is integrally formed on the open end side of the holding plate 15 via a bendable hinge 18. It can be freely engaged and detached from a locking step 19 formed on one side of the hem 12. A locking protrusion 2 is provided on one side of the outer wall of the buffer member 1.
0 is formed. Reference numeral 21 denotes a plate such as a cardboard board, and the plate 21 has a fitting hole 22 for the locking protrusion 20 and an insertion hole 23 for the latch 17 at each of the four corners. The plate body 21 is a top plate or a bottom plate that comes into contact with the upper and lower surfaces of the packaged article 2 . 24 is an outer box, such as a cardboard box.

The cushioning member 1, the holding plate 15, the latch 17, and the hinge 18 are molded by thermoplastic blow molding, and the thermoplastic used is polyethylene, polyamide, vinyl chloride, or the like.

When storing the article 2 in the outer box 24 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, 5 of the article 2 to be packaged. Next, the plate body 21, which will become the top plate or the bottom plate, is placed along the top or bottom surface of the article 2. The locking protrusion 20 of the buffer member 1 is inserted into the fitting hole 22.
, and then fold the presser plate 15 toward the buffer member 1 side, insert the latch 17 into the insertion hole 23 and engage the locking step 19 of the buffer member 1, and then close the buffer member 1.
is attached to the plate body 21. Then, put the item 2 in the outer box 2.
4 and the outer box 24 is closed, the packaged article 2 is packaged with its corners immovably supported on the inner surface of the outer box 24 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 21, so that the buffer member 1 may become misaligned when the article 2 is stored in the outer box 24.
The work of storing and packaging the article 2 in the outer box 24 can be easily performed without falling off. Further, even after being packaged in the outer box 24, the buffer member 1 will not be displaced in the same way.

Furthermore, the presser plate 15 is attached to a hinge 16 on the buffer member side.
Since the plate 21 is pulled from both sides of the hinge 18 on the latch 17 side, the locked state of the plate 21 is extremely stable and will not easily come off due to impact.

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

Incidentally, in the above embodiment, the latch 17 and the locking step 19 were formed on the buffer member as a receiving part for the latch, but the present invention is not limited thereto. A wide range of means for locking the member 1 can be used, such as forming a hole as a latch receiving portion of the buffer member and fitting the buffer member into the hole.

Effects of the invention Since the present invention is constructed as described above, it can be easily fixed to the top plate and the bottom plate, the buffer member can be prevented from shifting, and the plate can be fixed to the top plate and the bottom plate with two hinges. Since the package is compressed, the fixation is extremely stable, and the product to be packaged can be reliably protected without being easily dislodged by impact.
