PROBLEM TO BE SOLVED: To provide a packing box which can protect a packed object without causing damage even when external force such as a micro-vibration is applied during transportation or the like. SOLUTION: The packing box 1 receives an object 5 to be packed and a cushioning mechanism 3 inside a box body 2. The cushioning mechanism 3 includes a spring member 13 whose lower end is fixed to a predetermined member 12 on a side of a base plate 2a in the box body 2, a mount plate 14 which is designed to allow the object 5 to be mounted and fixed to an upper end of the spring member 13 separately from a side plate 2b of the box body 2, and a fixing means 16 for fixing the object 5 to the mount plate 14. Thus external force such as a micro-vibration applied to the box body 2 during transportation for example is absorbed by the spring member 13, and as a result the object 5 can be protected without causing damage.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a packing box for packing an article such as a recording medium or an electronic component when the article is transported.

[0002]

2. Description of the Related Art For example, when an article such as a recording medium or an electronic device is transported, various cushioning materials are used to avoid damage to the article caused by the application of an external force such as an impact or vibration applied during the transport. You need to protect the goods. In this case, in the conventional packing method, for example, the article is stored in a box body in a state of being wrapped with an air mat (buffer), or a foamed resin cushioning material is interposed between the article and the box body. To protect the goods. On the other hand, if a gap is formed between the box body and the cushioning material or between the cushioning material and the article, the article may move in the box body and be damaged. Therefore, when packing the articles, the movement of the articles in the box body is restricted by storing the box body, the cushioning material, and the articles so that a gap is not formed between the articles as much as possible. The applied external force is absorbed by the air mat or the foamed resin. As a result, damage to articles caused by external force applied to the box main body during transshipment work during transportation or when a transport vehicle crosses a step is prevented.

[0003]

However, the conventional packing method has the following problems. That is, in the conventional packing method, in order to restrict the movement of the goods in the box body,
The articles are packed so that no gap is formed between the box body, the cushioning material and the articles. However, in this packing method, micro-vibrations such as engine noise and road noise of the transportation vehicle transmitted to the box body during transportation are transmitted to the article via the cushioning material. For this reason, the conventional packing method has a problem that the article may be damaged due to the minute vibration. In this case, in particular, the winding of a tape such as a tape cartridge is liable to cause a winding deviation due to the micro-vibration, and the data recording surface or the tape edge of the tape may be damaged due to the winding deviation. In such a case, there is a problem that a data recording error or a reading error of recorded data occurs.

On the other hand, Japanese Patent Application Laid-Open No. Hei 10-137022 discloses that a cushioning material having a spring and a resin foam sandwiched between a pair of plates is provided along a side plate of a bag (surfaces which become upper, lower, left and right when holding the bag). There is disclosed a technology for protecting electronic devices such as personal computers from shocks by disposing them in a bag. However, in this cushioning material, since the pair of plates are connected via the resin foam, the micro-vibration transmitted to the side plate of the bag is reduced by the outer plate,
It is transmitted to the electronic device via the resin foam and the inner plate. For this reason, the disclosed prior art includes:
There is a problem that the electronic device may be damaged due to the minute vibration. In addition, since the cushioning material is simply disposed along the side plate of the bag, external force applied to the bottom plate and the top plate of the bag is directly applied to the electronic device. There is also a problem that it cannot be sufficiently protected.

The present invention has been made in view of the above-mentioned problems, and has been made in consideration of the above-described problems. Therefore, even when an external force such as microvibration is applied during transportation or the like, a package capable of protecting a package object without causing damage is provided. Its main purpose is to provide boxes.

[0011]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a packaging box according to the present invention will be described below with reference to the accompanying drawings.

First, the configuration of the packing box 1 will be described with reference to the drawings.

The packing box 1 is used when transporting recording media such as a magnetic tape cartridge or electronic equipment such as a personal computer by courier service, pallet service, air service, or the like. It is configured so that it can be protected from external force such as impact. Specifically, as shown in FIG. 1, the packing box 1 includes a box main body 2 and a buffer mechanism 3. The box body 2 includes a bottom plate 2a, side plates 2b, 2b,... And lids 2c, 2c,.
Is configured to be able to be stored. The box body 2 is made of, for example, a double-faced cardboard made of PP (polypropylene).

As shown in FIGS. 1 and 2, the cushioning mechanism 3 is configured to be detachable from the box body 2, and includes a cushioning material 11, a base plate 1
2. Coil springs 13, 13,..., Mounting plate 14, cushioning material 15, fixing belts 16, 16,.
7, 17,... The cushioning material 11
It corresponds to a first cushioning material in the present invention, and is attached to the lower surface of the base plate 12. The base plate (predetermined member in the present invention) 12 is formed of, for example, an aluminum flat plate or a resin plate having substantially the same size as the bottom plate 2 a of the box main body 2. Is side plate 2
b, 2b,. Also, the base plate 12
Notches 12a are formed on the four sides at the center in the width direction. The coil spring 13 corresponds to the spring member of the present invention, and extends and contracts in the up-down direction.
It is fixed to. In this case, in the buffer mechanism 3, five coil springs 13, 13,... Are used as an example. Further, as shown in FIG. 3, each coil spring 13 is fixed to the vicinity of four corners of the base plate 12 and the center of the base plate 12. In this packing box 1, even when the coil spring 13 is compressed by the weight of the packing object 5, contact between the upper surface of the cushioning material 17 and the lower surface of the mounting plate 14 is avoided, and during the transportation, For example, the free length and the spring constant are set in advance so as not to be fully contracted even when vibration or impact (hereinafter, both are also collectively referred to as “vibration etc.”) occurs. in this way,
Each of the coil springs 13 is fixed to the base plate 12 and the base plate 12 is configured to be detachable from the box main body 2.
As a result, assembling at the time of manufacturing the packing box 1 becomes easier as compared with a configuration in which the packing box 1 is directly fixed, the manufacturing cost can be reduced. On the other hand, the mounting plate 14 is formed of, for example, an aluminum flat plate or a resin plate, and its four sides are formed in a flat plate shape shorter than the corresponding four sides of the bottom plate 2a in the box body 2, respectively. Mounted on top. Also, on the upper surface of the mounting plate 14,
As shown in FIG. 4, a cushioning material 15 corresponding to a second cushioning material in the present invention is attached.

The fixing belt 16 corresponds to a fixing means in the present invention, and as shown in FIG.
And a fastener 16a is provided at the other end. The other end of the fixing belt 16 has a belt through hole 14 a, 14 b formed in the mounting plate 14.
are drawn out to the upper surface side of the mounting plate 14 through a. The fixing belt 16 is configured such that the entire length thereof can be appropriately adjusted by a metal fitting 16b, and fixes the packing object 5 placed on the cushioning material 15 to the placing plate 14. Cushioning material 1
Reference numeral 7 corresponds to a third cushioning material in the present invention, and is attached to the upper surface of the base plate 12 as shown in FIG. In this case, in a state where the package 5 is placed on the cushioning material 15, a gap is formed between the upper surface of the cushioning material 17 and the lower surface of the placing plate 14, and a large external force is applied to the cushioning material 17. 13.13... Are set to such a height that the upper surface thereof abuts (contacts) the lower surface of the mounting plate 14 in a state of being largely compressed. In addition, cushioning materials 11, 15, 17, 17.
Is molded of urethane foam as an example.

Next, a method of using the packing box 1 will be described with reference to the drawings.

First, the buffer mechanism 3 is housed in the box body 2.
At this time, the lower surface of the cushioning material 11 is in surface contact with the bottom plate 2a, and the vicinity of the four corners of the base plate 12 is the side plates 2b, 2b,.
Contact each other. In this state, the buffer mechanism 3 is housed in the box main body 2 in a state where movement in the horizontal direction in the internal space S of the box main body 2 is restricted. The movement in the vertical direction is regulated by the weight of the buffer mechanism 3 and the weight of the package 5 fixed to the buffer mechanism 3. Further, since the four sides of the mounting plate 14 are formed to be shorter than the corresponding four sides of the bottom plate 2a of the box main body 2, respectively, the side plates 2b, 2b,. A gap is formed in the gap. Next, as shown in FIG.
After placing the object 5 to be packed on the cushioning material 15, it is fixed with fixing belts 16. At this time, the coil springs 13, 13,...
Is slightly compressed, but the cushioning material 17 and the mounting plate 14
Are maintained in a non-contact state. In addition, the fixing belt 1
After the packing object 5 is fixed to the buffer mechanism 3 in 6, the buffer mechanism 3 can be stored in the box body 2. By storing the packing object 5 by this storing method, the packing operation is facilitated. Next, the lids 2c, 2c,... Of the box body 2 are folded and sealed to complete the packing of the packing object 5. Thereafter, the packing box 1 is loaded on a truck bed and transported, for example.

In this case, the mounting plate 14 to which the packing object 5 is fixed is supported only by coil springs 13, 13,... Therefore, when vibration or the like is applied to the box body 2, the vibration or the like is absorbed by the coil springs 13, 13,. In particular, as an effect that the conventional packing box cannot achieve, even if minute vibrations such as engine noise and road noise are transmitted to the bottom plate 2a of the box body 2 during running of the truck, the coil springs 13, 13,. Absorbs minute vibrations. Therefore, transmission of vibrations and the like (hereinafter, also referred to as microvibrations) to the packing target body 5 is reliably avoided. In addition, in this packing box 1, the bottom plate 2a and the base plate 1
The vibration and the like transmitted to the bottom plate 2a are slightly attenuated and transmitted to the base plate 12 by the cushioning material 11 disposed between the bottom plate 2a and the base plate 12. If the coil springs 13, 13,.
Absorbs. For this reason, transmission of vibration and the like to the package target body 5 is sufficiently avoided. Further, the object 5 to be packed is stored in the internal space S in a state of not contacting the side plates 2b, 2b,... And the lids 2c, 2c,.
Therefore, the side plates 2b, 2b... And the lids 2c, 2c.
Even if vibrations or the like are transmitted, the transmission of vibrations or the like to the package target body 5 is reliably avoided.

On the other hand, when a large vibration or the like is applied to the box body 2 due to, for example, the dropping of the packing box 1 or the passage of a transportation vehicle, as shown in FIG. The base plate 12 slightly moves down toward the bottom plate 2a by its own weight. At this time, the bottom plate 2a and the base plate 1
2 (the air around the cushioning material 11)
Move above the base plate 12 through the notches 12a, 12a,... Of the base plate 12. Therefore, as a result of the base plate 12 moving down smoothly, the cushioning material 11 is also elastically deformed smoothly and absorbs vibration and the like. At the same time, the amount of vibration transmitted to the base plate 12 to the mounting plate 14 is suppressed by compressing the coil springs 13. At this time, when the coil springs 13, 13,.
By contacting (contacting) 7, 17,...
7, 17,... Are elastically deformed by pressing. Therefore, the amount of vibrations and the like that cannot be completely absorbed by the elastic deformation of the coil springs 13, 13,. Further, vibrations and the like transmitted to the base plate 12 are absorbed by the cushioning members 11 and 17 and the coil springs 13 and 13.
Is not completely absorbed, the vibration and the like transmitted to the mounting plate 14 are absorbed by the elastic deformation of the cushioning material 15. As a result, the vibration applied to the box body 2 is reduced by the cushioning members 11, 15, 17 and the coil springs 13, 13,.
, Which is almost certainly absorbed, whereby the packaging object 5 is sufficiently protected.

As described above, according to the packing box 1, the external force (including impact, large vibration and minute vibration) transmitted to the box body 2 is absorbed by the coil springs 13, 13,. It is possible to effectively prevent breakage of the package 5 due to the application of an external force. According to this packing box 1, the cushioning material 11 is attached to the lower surface of the base plate 12 and the cushioning material 1 is attached to the upper surface of the mounting plate 14.
By adhering the box body 5, the external force applied to the box body 2 can be sufficiently absorbed by the cushioning members 11, 15 and the coil spring 13, so that the damage to the packing object body 5 caused by the external force applied to the box body 2 can be reduced. It can be reliably prevented. Furthermore, according to this packing box 1, the base plate 1
Since the cushion members 17, 17,... Are arranged between the mounting plate 14 and the mounting plate 14, when the coil springs 13, 13,. As compared with the configuration in which only the springs 13, 13,... Are provided, the external force applied to the box body 2 can be reliably reduced. At the same time, in this packing box 1,
Since a gap is formed between the upper surface of the cushioning material 17 and the lower surface of the mounting plate 14 in a normal state where no external force is applied,
In particular, it is possible to prevent the transmission of the micro-vibration to the packing object 5 via the cushioning material 17.

Next, the difference in the influence of vibration or the like during the transportation of the packaging object 5 packed using the packaging box 1 and the packaging object 5 packed by the conventional packaging method,
In particular, the difference between the effects of the micro vibration will be specifically described with reference to FIG.

First, ten magnetic tape cartridges are stored in the packing box 1 as the packing object 5. Further, as a conventional packing method, 10 magnetic tape cartridges are packed in an air mat and stored in a cardboard box. In this case, a magnetic tape cartridge having a neat winding shape with no looseness of the tape and no step-down or the like is used. After simultaneously transporting the packing box 1 and the cardboard box in this state by courier using the same vehicle, the state of each magnetic tape cartridge is inspected. In addition,
As a method of inspecting the magnetic tape cartridge, the amount of looseness of the winding and the quality of the winding are inspected. In this case, the number of notches (the amount of rotation of the tape reel) of the hub gear from the start to the completion of rewinding is measured by rewinding the transported magnetic tape cartridge until there is no looseness. In addition, about winding figure,
The presence or absence of the drop is visually inspected.

As shown in FIG. 6, a magnetic tape cartridge packed by a conventional packing method has an average of 4
In contrast to the 8.2-notch winding looseness, the magnetic tape cartridge transported using the packing box 1
On average, only 4.4 notch loosening occurred.
Regarding the winding form, the conventional packing method has a step drop in more than half of the magnetic tape cartridges, while the packing box 1 uses the magnetic tape cartridge in all the magnetic tape cartridges. No drop has occurred. As described above, by using the packing box 1, it is possible to sufficiently avoid particularly the influence of the micro-vibration. As a result, the packing object 5 such as a magnetic tape cartridge can be transported while being appropriately protected.

It should be noted that the present invention is not limited to the above embodiment of the present invention, but can be appropriately modified. For example, in the packing box 1 according to the embodiment of the present invention, the cushioning materials 11, 15, 1
, But these cushioning members are not essential components, and the coil springs 13, 13,.
・ Packing object 5 caused by application of external force only by itself
Can be sufficiently prevented. In addition, packing box 1
Then, the coil springs 13, 13,.
However, it may be directly fixed to the bottom plate 2a of the box body 2. Further, it is of course possible to fix the packing object 5 to the mounting plate 14 in a state of being packed with an air mat.

[0025]

As described above, according to the packing box of the present invention, the lower end of the packing box can be placed on a predetermined member on the bottom plate side of the box body or a spring member fixed to the bottom plate, and the packing object can be placed thereon. And a mounting mechanism fixed to the upper end of the spring member in a state of being separated from the side plate of the box main body, and fixing means for fixing the object to be packed to the mounting plate, thereby forming a buffer mechanism. Because the mounting plate on which is fixed is held by the spring member, for example, external force such as micro-vibration applied to the box body during transportation is absorbed by the spring member,
The object to be packed can be protected without causing damage. Therefore, the packing object can be safely transported.

According to the packing box of the present invention, the base plate is provided above the bottom plate of the box body and the lower end of the spring member is fixed. As a result of easier assembling during the production of the packaging box as compared to a configuration in which the members are directly fixed,
The manufacturing cost can be reduced. In addition, since the object to be packed can be stored in the box body after the object to be packed is mounted on the mounting plate, the packing operation can be easily performed.

Further, according to the packing box of the third aspect,
By disposing the first cushioning material between the bottom plate and the base plate of the box body, the external force transmitted to the box body is absorbed by the first cushioning material, so that the object to be packed is reliably protected. be able to.

Further, according to the packing box of the fourth aspect, since the second cushioning member is disposed on the upper surface of the mounting plate, extremely slight vibration is transmitted to the mounting plate via the spring member. Even if it is done, the second cushioning material absorbs the micro-vibration, so that the packing object can be protected more reliably.

According to the packing box of the fifth aspect, since the third cushioning member is provided, even when an excessive external force is applied to the box body and the spring member is largely compressed, the third cushioning member is provided. Since the cushioning material is elastically deformed and absorbs external force, the object to be packed can be more reliably protected.
