Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package used as a cushioning member for a packaging box used to prevent damage to the device during transportation or the like.

[0002]

2. Description of the Related Art As a cushioning member for packaging, foamed styrene resin material is widely used because of its excellent shock absorption, its shape can be freely formed, and its lightweight and low cost. Has been done.

[0003]

However, although the styrofoam has excellent characteristics as a cushioning member as described above, it requires a high-priced mold according to the shape of the packaged product, which is expensive. In addition, in the case of disposal, styrofoam does not spontaneously disappear, and a large disposal volume is required semipermanently, which poses a serious environmental problem. Also, when incinerated, it will damage the incinerator due to high temperatures and generate harmful gas. There are also environmental problems such as.

For this reason, an air-filled elastic bag body has attracted attention as a cushioning member replacing styrofoam, and in this regard, JP-A-1-45277 and Japanese Utility Model Application Laid-Open No. 57-21573.
Although the proposals in each of the gazettes have been made, there are practical problems such as breakage and handling that are both because they are bags that come into direct contact with the object to be packaged, and the gazette of Japanese Utility Model Publication No. 63-144485. However, since the foam itself has a structure in which the foam itself is filled with air, it is directly accompanied by the cost obstacles and environmental problems of the polystyrene foam.

As a result of solving these problems and improving the present invention, as a result, it has a shock absorbing capacity comparable to that of Styrofoam, has good handleability, has a stable mounting position, and can be easily disposed of without problems. The purpose of the present invention is to provide a package made of a cushioning member.

[0006]

The above object is to provide a cushioning member which is interposed between a device and a packaging container accommodating the device and is used for protecting the device, and which is a flexible member having air filled therein. An air cushion composed of a bag body, and a package comprising a cushioning material made of a combination of a corrugated cardboard material or a cardboard containing the air cushion, and an intervening device between the device and a packaging container accommodating the device. The shock-absorbing member used to protect the device from shocks is composed of a combination of an air cushion formed of a flexible bag body filled with air and a triangular corrugated cardboard material or cardboard containing the air cushion. And a side wall of the corrugated board is formed on the outer wall of the device, and a side edge is formed on the inner wall of the packaging container by a cushioning member. .

[0007]

[Examples] Examples of the material of the cushioning member that can replace styrofoam include corrugated cardboard material, pulp mold material, and air cushion material in view of the environment, the function of absorbing shock, and the cost.

As a result of conducting a buffer test and a practical test on each of these materials, the pulp mold is suitable as a buffer material for small and lightweight objects such as cameras, but electric products such as copying machines, televisions, air conditioners, etc. It was found to be unsuitable as a cushioning member for large heavy objects such as.

On the other hand, the corrugated board material is effective against static load, and the air cushion is excellent in absorbing dynamic load, that is, shock. We have come to propose a cushioning member that combines a cushion.

The structure and characteristics of the cushioning member according to the present invention will be described below.

The air cushion used for the cushioning member is a Tricon TC as shown in FIGS. 1 (a) and 1 (b).
A triangular-pyramidal cushion called (product name) and Fig. 1
There is a flat type air mat AM as shown in (c), both of which are new type cushioning materials made of PET resin, which has the characteristic that the volume can be made extremely small when the filled air is removed, and it can also be incinerated. Therefore, no harmful gas is generated during incineration.

The above-mentioned tricon TC is the tricon TC1 in an individually independent form as shown in FIG.
As shown in (b), Tricon TC2 in a chain-linked form
And either M or S type is used depending on the purpose of use.

Further, in the case of using a plurality of tricon TC1s and the case of using TC2s, there is an advantage that the buffering function is not largely lost even if one air escapes because an independent air chamber is formed. , Meanwhile, air mat AM
Has a merit that it can receive items to be packaged over a wide area because it is a flat plate.

In order to compare the cushioning performance of each of the above air cushions with the conventionally used corrugated board material and styrofoam material, an inclined drop test was conducted assuming that the packaging device is 70 cm × 57 cm × 40 cm in size and 100 kg in weight. Carried out. The tilt drop test was performed based on JIS Z0205.

As a result, as shown in FIG. 2, each of the air cushions has a high shock absorbing capacity, and especially, the Tricon TC2.
It was confirmed that (M) (those in which a plurality of Tricon TC1 (M) are continuously arranged) and the air mat AM maintain stable cushioning performance comparable to that of the polystyrene foam material even when repeatedly dropped.

Further, the present inventor conducted various tests described below to confirm the practical performance of the air cushion.

First, in order to understand how much load each air cushion can withstand by itself, the burst load was examined by a compression tester.

FIG. 3 is a load-strain diagram thereof, in which the vertices of each graph are rupture points, and the tricon TC1 (M), TC1 (S)
Was found to be larger than the air matte AM and superior in compression resistance.

The present inventors picked up Tricon TC1 as a cushioning member that can be used as a styrofoam material, and confirmed the presence or absence of air leakage and elongation of the material under pressure for a long period of time.

The test is a Tricon TC1 arranged on a flat plate.
A weight of 150 kg was placed on (S) for 6 months, and the amount of strain generated during that period was measured.

As shown in FIG. 4, the change in the strain amount occurs especially in the period of about one month in the initial stage (5%), and the change thereafter is only about 1% in 6 months, and about 6% as a whole. It was confirmed that the Tricon TC1 was extremely small and stable, and the creep property was excellent.

As described above, it has been proved that the Tricon TC has extremely excellent characteristics as a cushioning member used in the packaging container of the apparatus, but since the Tricon TC itself is a flexible body, it is attached to the specified portion. It is difficult to fix, and it may be damaged if you touch the edge of the device directly.
Furthermore, it is difficult to design the volume in terms of form, and there were a number of difficulties when used alone.

Therefore, the inventor of the present invention considers the combined use with other cushioning members in order to make up for such drawbacks of the Tricon TC, and by combining it with a corrugated board material or a cardboard that can clear the environment, the cushioning result is high and the practicality is excellent. It was possible to realize a cushioning member.

The corrugated board or cardboard used here is J
Corrugated board materials such as JIS Z1516 and 1537 made from materials typified by IS P3902 and P3904 and JIS P0001.
Materials such as kraft pulp of No. 3006 and 4001 paperboard of No. 3006, which are defined in terms of paper and pulp, were used as cardboard.

Also, a product obtained by laminating the above materials can be applied as the corrugated cardboard material of the present invention.

FIG. 5 shows a structural example of a unit of a cushioning member made of a combination of a Tricon TC and a corrugated board material. FIGS. 5 (a) and 5 (b) show a triangle or a tricon TC2 connected in a chain. A corrugated cardboard 1A or 1B folded in a quadrangle is included in the corrugated cardboard 1A and 1B.
B and the respective flat corrugated cardboards 2 in contact with both sides thereof are joined with a tape 3 so as to integrally fix the above-mentioned tricon TC2 in the corrugated cardboards 1A and 1B.

Further, FIGS. 5 (c) and 5 (d) show that the above-mentioned tricon TC2 is integrally fixed by being enclosed in a corrugated cardboard 1C or 1D wound in a triangle or a quadrangle.

The pressure-resistant strength of the corrugated board can be utilized by making the direction of the core liner of the corrugated board perpendicular to the folding line (fold) of the corrugated board.

As the tricon TC to be encapsulated, instead of the chain-connected tricon TC2 shown in the examples, the individually independent tricon TC1 described above is encapsulated in the range of one or more depending on the size of the unit. Alternatively, the type M or S is selected in accordance with the required impact absorbing power when using either the tricon TC2 or tricon TC1.

In order to confirm the cushioning ability of the cushioning member made of corrugated board material containing Tricon TC, the inclined drop test previously carried out together with the corrugated board material and the polystyrene foam material was carried out again.

The test was carried out using a combination of the Tricon TC2 and the double-faced corrugated board S-2 member defined by JIS Z1516 in the structure shown in FIG. 5D, and the result is shown in FIG. As shown in FIG. 5, it was confirmed that it has a shock absorbing capacity exceeding that of the styrofoam material in several repeated drops.

5 (a) to 5 (c), or the same buffering effect was confirmed in a case where a plurality of tricon alone were inserted in the corrugated board.

A compression test was carried out on a corrugated cardboard 1D shown in FIG. 5 (d) containing six independent tricon TC1 (s), and the result was a load of 5000 kgf as shown in FIG. It was proved that the strain could be put to practical use with sufficient withstand voltage in the practical use load range of 500 to 600 kgf within the diagonal line.

FIG. 8 shows the construction of the packaging body of the copying machine A using the cushioning member composed of the air cushion and the corrugated board material.

A plurality of protrusion rows 13A are formed inside the bottom surface by cutting and bending, and the cushioning member 11 is housed between the protrusion rows 13A to fix their positions.

On the other hand, the cushioning members 12A to 12D are fixed between the respective corners in the bottom box 13 and the apparatus A, fixed in position, and kept in an upright posture.

Reference numeral 14 is an upper board made of corrugated board which covers the upper surface of the apparatus A, and encloses an air cushion in a pair of cushioning members 14A integrally formed by cutting and bending.

Each of the above-mentioned cushioning members arranged around the device A is a cardboard packaging box whose lower part is opened together with the device A.
Covered by 15 and pedestal 10 by packing belt 20
By being integrated with the above, it is brought into close contact with the outer wall of the device A, and its buffering and absorbing effect is exhibited.

Of the above-mentioned cushioning members, particularly the cushioning member
9A to 12D and 14A are attached to the respective corners and the upper surface of the apparatus A in a balanced manner so that FIG.
As shown in FIG. 2, they are connected to each other through a pair of corrugated board materials, which simplifies the work of attachment and detachment. By hitting the portion, it is easily and surely interposed at a predetermined position and is prevented from moving due to vibration or the like. Further, even if the bending length is set to an arbitrary design length in accordance with the abutting portion of the product, it is possible to easily deal with the manufacturing.

As the air cushion contained in each of the cushioning members, the Tricon TC2 or the air mat AM is excellent because of its shape and can be easily attached and detached.

Further, when it is necessary to interpose a cushioning member at the corners of the bottom surface or the top surface of the device A, two block-shaped corrugated cardboard materials 20A containing Tricon TC1 as shown in FIG. 20B can be integrated, preferably by adhesion or the like, to be used as the corner cushioning member 20 shown in FIG. 10 (b).
