Description

[Detailed Description of the Invention] This invention relates to a cushioning material interposed between a packaging box and an object to be packaged.

When packaging items such as the outdoor unit of a split type air conditioner, conventionally, as shown in Figures 1 to 3, a lower cushioning material made of styrofoam is placed on a base a, and this The packaged item C is placed on the lower cushioning material C, and the upper cushioning materials e and e made of styrofoam are placed on top of the packaged item C via a protective paper d, and the packaging box f is inserted from above. and finally fastened with band g9g.

Therefore, the upper and lower cushioning materials S and E can protect the packaged object C from the shocks applied during transportation, but since the cushioning materials S and E are made of styrofoam, they are thick and make the packaging box large. There is the inconvenience of doing so.

Furthermore, covering the entire upper part of the packaged object C would increase the material cost, so the upper cushioning material e is divided to form a space, but the material falls into the packaging box f facing this space. If a load is applied, there is a risk that the packaging box f may be deformed and damage the packaged object C, and there is also a problem in the processing of the foamed polystyrene cushioning material, and improvements are desired.

This idea was created by focusing on the above-mentioned circumstances, and its purpose was to create a product by cutting out a piece of cardboard, which not only protects the packaged items, but also provides them at a low cost. The aim is to provide a cushioning material that can

An embodiment of this invention will be described below with reference to the drawings.

Reference numeral 1 in FIGS. 4 to 6 is a corrugated paperboard for forming the cushioning material A, which is formed into a rectangular shape.

On both sides along the longitudinal direction of this corrugated paper 1, there are two
Score lines 2, 2 are provided in the book, and two parallel score lines 3.3 are provided on both longitudinal edges.

Therefore, the corrugated paperboard 1 has the above-mentioned score lines 2, 2.3,
3, it is divided into two parts: a protection frame 4 on the outer periphery and a protection plate 5 on the inside.

Furthermore, crease lines 5a and 6b are formed on the inner peripheral edge of the protective frame 4, respectively.
, 6c, 6d are provided with reinforcing pieces 7a, 7b, 7c, and 7d, and these reinforcing pieces 7a.

7b, 7c, and 7d are fold lines 6a and 6b, respectively.

It is valley-folded along lines 6c and 6d and adhered to the upper surface of the protective frame 4.

Therefore, a fitting hole 8 is formed in the protective frame 4 to fit an object to be packaged, which will be described later.

On the other hand, the protection plate 5 is divided into two by a crank-shaped cutting line 9 at its longitudinally intermediate portion, and the wide section matches the width of the protection frame 4.

Therefore, the two divided protection plates 5, 5 are integrally provided with holding pieces 5a, 5a each having a width narrower than the width of the protection frame 4.

These protection plates 5, 5 are bonded point-symmetrically to the upper surface of both longitudinal ends of the protection frame 4, and are integrally formed.

When packaging an object using the cushioning material A constructed in this way, the cushioning material 11 made of styrene foam is housed in the base 10, as shown in FIG.

Next, a packaged object 12 such as an outdoor unit of a split type air conditioner is placed on this buffer 11, and a buffer configured as described above is placed on top of this packaged object 12 with a protective paper 13 interposed therebetween. Attach material A.

That is, the fitting hole 8 of the cushioning material A is fitted into the upper part of the object to be packaged 12, and the protection plates 5, 5 are joined to the upper surface of the object to be packaged 12.

In this state, a packaging box 15 having an opening 14 on the lower surface is fitted from above, the lid 16 is closed, and the packaging is completed by fastening with bands 17 and 17 as shown in FIG.

In addition, in the above embodiment, the cushioning material A is used as the packaged object 1.
2, but it may also be placed at the bottom and protected by the same cushioning material above and below.

As explained above, in this invention, the protective frame and protective plate are formed by cutting out a piece of corrugated paper, so the material can be used effectively, and the fitting hole of the protective frame can be inserted into the packaged item. Since the protective plate is fitted to the top or bottom surface of the packaged item, it has the effect of restraining and protecting the packaged item, and since it is made of corrugated pole paper,
It is thinner than Styrofoam, and there is less space between the packaged item and the packaging box, which has the effect of preventing deformation and making the packaging box smaller.

Claims (1)

[Scope of utility model registration request] In a cushioning material interposed between a packaging box and an item to be packaged stored inside the box, a piece of corrugated paper is cut out along its periphery to fit into the item to be packaged. A rectangular protective frame having a mating hole is formed, and a rectangular protective plate having a long side wider than the mating hole is formed on the inside by dividing the rectangular shape into two in the longitudinal direction. The inner circumferential edge thereof is bent outward to provide a reinforcing piece that overlaps with the upper surface thereof, and the two protection plates are integrally constructed by straddling and superimposing each of the reinforcing pieces at both ends in the longitudinal direction of the protection frame. A cushioning material characterized by:
