DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packaging cushion which is housed in a packaging box and protects commodities from impact, which is assembled from cardboard or other cardboard.

[0002]

2. Description of the Related Art Conventionally, foamed styrofoam cushions have been widely used as a buffer to be accommodated in a packaging box. Recently, however, there has been a problem of disposal after use or storage when not in use. Due to space issues, cardboard or other blanks made of cardboard are bent and assembled into the mainstream.

A conventional cardboard or other packaging cushion made of cardboard requires a lot of time to assemble a plurality of blanks, or a single blank. A buffer space was not formed on any of the upper, lower, left, right, and end walls of the packaging box, and the buffer effect was insufficient.

Therefore, the present invention is composed of a single blank, is easy to assemble, and when housed in a packaging box, can be attached to any one of the upper, lower, left and right walls and the end wall of the packaging box. A predetermined buffer space is also formed between them, and it is intended to obtain a packaging buffer having an excellent buffer effect.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a packaging cushion assembled from cardboard or other cardboard is constructed as follows.

That is, a pair of opposed side plates which are bent to one side of the end plate via folds are respectively connected to a pair of opposed sides of the end plate, and the other pair of opposed sides of the end plate are provided. Each of the outer leg plates is bent to the other side of the end face plate via a fold, and has a length longer than that between the opposing wall plates. An outer end plate that is bent in a row is provided continuously, and an inner leg plate that is bent inward is connected to the leading edge of the outer end plate.The end plate and the opposing wall plate that intersect the inner leg plate are connected to each other. ,
The slit into which the inner leg piece plate is inserted has a configuration in which a slit that fits with the slit is formed at the tip of the inner leg piece plate.

[0007]

As described above, the packaging cushion of the present invention is composed of one blank.

[0008] Then, in a square frame formed by the space between the opposing wall plates and the inner leg plate intersecting with the opposing wall plate, the end face of the product is brought into contact with the inner surface of the end face plate. When the product is fitted and the product is accommodated in the packaging box together with the packaging cushion, the length between the inner wall surface of the packaging box and the product is longer than the interval between the opposing wall plates on both sides of the opposing wall plate. The outer leg piece plate has a space that protrudes on both sides between the opposing wall plates, the outer space of the inner leg piece plate has the space of the width of the outer end face plate, and the outer leg piece plate has the space of the outer leg piece plate outside the end face plate. The space corresponding to the width is formed as a buffer space.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The packaging cushion of the present invention is assembled from a cardboard blank such as a cardboard shown in FIG.

The blank is configured as follows.

First, a pair of upper and lower opposing side edges of a rectangular end plate 1 whose left and right lengths are substantially equal to the left and right lengths of the end walls of the packaging box are respectively provided via folds. The opposed wall plates 2 are bent at right angles to the end face plate 1 so as to face each other.

On both left and right sides of the end face plate 1, the length in the vertical direction is longer than the length in the vertical direction of the end face plate 1. An outer leg piece plate 3 having a length longer than the interval between the wall plates 2 is continuously provided via a fold. The outer leg plate 3 is bent at a right angle to the end face plate 1 on the side opposite to the facing wall plate 2.

An outer end face plate 4 is connected to the left and right end edges of the outer leg piece plate 3 via a fold line. The outer end plate 4 is bent inward at a right angle to the outer leg plate 3 and parallel to the end plate 1.

The left and right end edges of the outer end face plate 4 have inner legs of which the length in the left and right direction is substantially the same as the combined length of the opposing wall plate 2 and the outer leg plate 3. The one plate 5 is continuously provided via a fold. The inner leg plate 5 is bent inward in a direction orthogonal to the outer end plate 4, and the inner leg plate 5 and the opposing wall plate 2, which intersect the inner leg plate 5, are provided with the inner leg plate 5. Is inserted into the opposite wall plate 2
The inner leg piece plate 5 is provided with a slit 7 at the distal end thereof, which fits the distal end portion of the opposing wall plate 2 from the middle. The light end portion of the inner leg piece plate 5 sandwiched between the slits 7 is formed to be slightly shorter than both ends. 6 is easy to insert.

A notch 8 is formed at the leading edge of the opposing wall plate 2 located on an extension of the slit 6 formed in the end face plate 1 and the opposing wall plate 2, and is engaged with the notch 8. A mating piece 9 is formed at the tip of the slit 7 of the inner leg piece plate 5.

The blank of FIG. 1 constructed as described above is assembled and used as follows.

First, the opposing wall plate 2 is bent at right angles to the end face plate 1. Next, the outer end plate 4 and the inner leg plate 5 are bent inward while the outer leg plate 3 is bent at right angles to the end plate 1 on the opposite side to the opposing wall plate 2, and the inner leg plate 7 is bent. The tip is inserted into the slit 6 of the end face plate 1 and the facing wall plate 2, and the outer end face plate 4 is bent at right angles to the outer leg plate 3, and the inner leg plate 5 is bent at right angles to the outer end plate 4. . Thereafter, when the locking piece 9 at the tip of the inner leg piece plate 5 is engaged with the notch 8 at the tip edge of the opposing wall plate 2, as shown in FIG. 3, the assembly of the packaging cushion of the present invention is completed. Complete.

[0018] The cushioning body for packaging is formed by the opposing wall plate 2.
The end face of the product is fitted into a square frame formed by the space and the inner leg piece plate 5 intersecting with the facing wall plate 2 so as to abut the inner surface of the end face plate 1. As shown in FIG. 4, the container is used in a packaging box A together with the product.

[0019]

As described above, the packaging cushion of the present invention is composed of a single blank, is easy to assemble, and when housed in the packaging box, the upper, lower, left, and right sides of the packaging box are provided. Since a predetermined buffer space can be formed between any one of the wall surface and the end wall and the product, there is an effect that the buffer effect is excellent.
