Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a package for stacking a plurality of articles to be packed one above the other and packing the articles, wherein a bendable cut portion serving as a cushioning material is sandwiched between the articles to be packed. More particularly, the present invention relates to a package for efficiently packing a solar cell module in storage or transportation.

[0002]

2. Description of the Related Art As a simple storage method for storing objects, a method of stacking a plurality of layers vertically is often used. this is,
By utilizing the shape, strength, and own weight of the laminate, it is a simple storage method when the load does not collapse with some force. However, in the case of safer storage or transportation, in order to more reliably prevent damage or collapse of the stack, provide appropriate cushioning between the stacks or use packing boxes. Need to be

[0003] When the object is in the form of a plate, the shape is suitable for lamination, the thickness direction being the smallest dimension side is defined as the height direction, and the plane on the larger dimension side is defined as a substantially horizontal lamination surface and a plurality of layers are vertically arranged. By stacking them, they can be stored easily. This means that, for example, there are some steps between the aluminum frame housing and the light-receiving surface side, such as a solar cell module, a bent portion for installation at the end, and a small protrusion such as a terminal box. The same is true for a generally plate-shaped object having a flaw. However, it is necessary to consider the steps, bends, and protrusions when laminating, and to devise cushioning materials and packing boxes.

[0004] For example, also in the case where a plurality of roughly plate-shaped solar cell modules are packed and used for storage, transportation, and the like, a method of stacking a plurality of solar cell modules vertically is often employed. In this case, a method of individually packing each solar cell module and then stacking the solar cell modules one above the other, or a method of stacking a plurality of solar cell modules vertically and using a cushioning material between the solar cell modules and packing a plurality of solar cell modules in a lump is used. The cushioning material is used for the purpose of preventing damage due to contact between the solar cell modules and preventing collapse of a load when stacked up and down depending on the form of the solar cell modules.

Conventionally, as this type of package, for example, a package having a configuration shown in FIGS. 9 and 10 is known. 9 and 10 are cross-sectional views of the packaged object in the width direction.

[0009] In the package shown in FIG. 9, a substantially plate-shaped aluminum frame type solar cell module having a substantially rectangular cross section in the width direction is the package 4, and the package 1 is made of a cardboard box 1. 4 are individually packaged one by one and then laminated.

[0007] In the package shown in FIG. 10, an approximately plate-shaped roof tile-type solar cell module having a substantially U-shaped cross section in the width direction is a packaged object 5, and a rectangular cushioning material 1 is provided.
The packing objects 5 are stacked one on top of the other using 01, and packed in a lump in a packing box 1 made of cardboard. If the rectangular cushioning material 101 is not provided, the packing object 5 having such a cross-sectional shape has a small contact area at the time of lamination, and thus is likely to collapse. In other words, the rectangular cushioning material 101 is also used to prevent the objects 5 to be packed from coming into contact with each other and to prevent the objects 5 to be packed from having a small contact area at the time of lamination, from collapsing.

[0008]

However, the conventional package has the following problems.

In the package shown in FIG. 9, the articles 4 to be packaged are individually packed one by one, and then stacked. This method is suitable when, for example, the final seller of the packaged article 4 individually sells to the end user one by one according to the purpose of use of the packaged article. However, when a plurality of packages are sold to the end user in a lump, for example, this method increases the amount of packaging material used, which increases the material cost and the disposal load.

[0010] In addition, since the packages are packed one by one, there is a problem that it takes time to pack and unpack. In FIG. 9, a roughly plate-shaped aluminum frame type solar cell module whose cross-sectional shape in the width direction is approximately square is taken as the packaged object 4. For example, the tile-bar type solar cell module shown in FIG. Depending on the shape of the item to be packed, there are projections such as output terminal boxes in some parts, and in order to protect that part, the shape of the packing box and the addition of cushioning material etc. Is needed.

The package shown in FIG.
The objects to be packaged 5 are stacked up and down while using a plurality of packages, and a plurality of the packages 5 are packed in a lump. Note that an auxiliary cushioning material 102 is attached for the purpose of protecting the protrusion of the uppermost packaged object. This kind of packaged object 5 is used for a roof, and a plurality of the objects to be used are used at one time at a place of use.
01 are stacked one above the other and packed in a lump. However, since the shape is substantially "U-shaped", a rectangular cushioning material 101 having a certain thickness is required, and the packaged object 5 is a solar cell module, and a precision component region called a photoelectric conversion element portion is required. Therefore, the material, size, shape, and the like of the rectangular cushioning material 101 require appropriate consideration and restriction conditions. In consideration of the material cost of the packaging material, the environmental load at the time of disposal, and the like, it is desired to use a packaging method that reduces the amount of the packaging material used and has a high degree of freedom in selecting a material with a small environmental load.

If the cushioning material is easily reduced in the package shown in FIG. 10, a different problem may occur. This will be specifically described with reference to FIG. In the package shown in FIG. 11, the rectangular cushioning material 101 of the package shown in FIG. 10 is omitted, and the small cushioning material 103 is sandwiched only in the vicinity of the portion where the objects to be packed come into contact with each other. Note that an auxiliary cushioning material 102 is attached for the purpose of protecting the protrusion of the uppermost packaged object.

A disadvantage of this method is that it is vulnerable to lateral displacement of the cushioning material 103 and the packaged object 5. If the cushioning material 103 is displaced sideways and comes off the pinched part,
It does not serve as a cushioning material that was the original purpose,
Since the shape of the packaged object 5 is generally "U-shaped", a problem such as collapse of the load occurs if the packaged object 5 is shifted sideways beyond the contact width. It is out of the question if the packaging materials are omitted and the functions such as safe storage and transportation, which are the original purposes of the packaging, are not satisfied.

In the case of this method, a member for preventing the lateral displacement of the cushioning material 103 is separately provided, and for preventing the lateral displacement of the article 5 to be packed, for example, the packing box 1 made of cardboard is changed to a material that is less flexible. New considerations and restrictions will be required.

Therefore, an object of the present invention is to reduce the amount of packaging material used while satisfying functions such as safe storage and transportation of the packaged objects, and to increase the degree of freedom in selecting the packaging material. Another object of the present invention is to provide a package which reduces necessary material costs and disposal load, is easy to collect when reused, and has good workability in packing and unpacking.

[0016]

In order to achieve the above object, according to the present invention, there is provided a package for packing a plurality of articles to be packed one above the other, which can be folded partially. It has an upright surface having a notch, and the bent notch has a function as a cushioning material by being sandwiched between objects to be packed.

According to another package according to the present invention,
A packing material for stacking a plurality of articles to be packed vertically and packing them, and having an upright surface having a partially bendable cut portion, wherein the upright surface and / or the bent notch portion are formed with respect to the to-be-packaged object. It is characterized by having a function as a fixing material for preventing displacement in the direction of the lamination surface.

In any one of the above-mentioned packages, it is preferable that the area of the cut portion is smaller than the area of the lamination surface of the article to be packed.

Further, it is preferable that the object to be packed has a substantially plate shape.

Further, at least a part of the upright surface having the cut portion may define the outermost surface of the package.

The upright surface having the cut portion is preferably formed of corrugated cardboard.

Alternatively, the upright surface having the cut portion is preferably formed of an elastic body.

It is preferable that the above-mentioned packaged object has a portion in the lamination surface where contact is to be avoided, and the bent cut portion contacts the portion where the contact is to be avoided.

Further, it is preferable that the packaged object has a portion having relatively low mechanical strength in the lamination surface, and the bent cut portion is in contact with the portion to avoid the portion having low mechanical strength.

Further, it is preferable that the packaged object has a projection in the lamination plane, and the bent cut portion is in contact with the projection, avoiding the projection.

It is suitable that any one of the above-mentioned objects to be packed is a solar cell module.

With the structure of the package according to the present invention, the folded cut portion is sandwiched between the objects to be packed, thereby exhibiting a function as a cushioning material. In addition, since the upright surface and / or the bent cut portion abuts so as to sandwich a part of the object to be packed, it functions as a fixing material for preventing the object to be packed from being displaced in the stacking surface direction.
Furthermore, since the cut portion only cuts the upright surface, manufacture is very easy, and the amount of use of the package can be reduced.

At the time of packing, it is only necessary to pack while bending the cut portion, and packing is very easy. Since the notch is only formed by bending and remains connected to the upright surface, it is possible to prevent displacement of the notch in the packed state. Further, when the package is collected, if the cut portion is bent back, the package can be easily returned to the flat body, and the package can be compactly collected.

[0029]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below, but the present invention is not limited to these embodiments.

The package according to the present invention is a general term for members used when packing an object to be packed such as a solar cell module, and is a package in which a plurality of objects to be packed are stacked vertically and packed.
The concept includes a packing box that is a box-shaped packing member, a sheet-like packing material having a partially bendable cut portion, and the like. In addition, an auxiliary cushioning material is used as necessary, for example, for the purpose of protecting the protruding portion of the packaged object.

(Packing Box) The packing box in the present invention is a box-shaped packing member constituting the packing body, and mainly partitions the outermost surface of the packing body.

In the packing box, a packing material having a cut portion which can be partially bent is fitted as an upright surface along the inner surface, but the upright surface of the packing box is inserted without loading the planar packing material. A bendable notch may be formed in itself.

For example, when the packing box has a hollow rectangular parallelepiped shape, a packing material having two notches is fitted along opposing inner surfaces of the packing box. The arrangement is not particularly limited as long as it can be reliably maintained in the state of being sandwiched between them.

As a material for the packing box, it is preferable to use a material having a cushioning property so that the article to be packed can be easily stored. However, in consideration of a disposal load and convenience, a cardboard card which is usually used is used. Is preferred.

(Packaging Material Having Cuts) The packing material having cuts in the present invention is a planar packing member constituting a package, and is mainly used by being fitted into a packing box.

This packing material is mainly fitted along the inner surface of the packing box to form an upright surface, and has a cutable portion in a part of the surface. However, the present invention is not limited to this arrangement. For example, when packing two vertical rows of objects to be packed in a packing box, they are arranged between two vertical rows of objects to be packed.

As described above, the packaging material having the cutout is fitted as an upright surface along the inner surface of the packaging box, but can be bent on the upstanding surface itself of the packaging box without loading the planar packaging material. A notch may be formed. In this case, the planar packing material having the cut portion is omitted. In this configuration, if the packaged material itself has a certain level of mechanical strength, the strength of the packaged material is also utilized to secure the strength of the entire packaged product, and the amount of packaging material used is further reduced. It is more preferable because it is possible.

For example, when the packing box has a hollow rectangular parallelepiped shape, a packing material having two notches is fitted along opposing inner surfaces of the packing box. There is no particular limitation as long as it is determined according to the shape and the state in which the bent cut portion is sandwiched between the objects to be packed can be reliably maintained. That is, the size and shape of the packaging material having the cutouts are determined according to the packaging box, and if the packaging material has a size and shape that can be securely stored in the packaging box while being addressed to the item to be packed. There is no particular limitation.

As the material constituting the packaging material having the cutout portion, it is preferable to use a material having a buffering property so that the packaged material can be easily stored. However, it is generally used in consideration of the disposal load and convenience. It is preferable to use corrugated cardboard. Also, when focusing on the function of the fixing member for preventing a position shift in the stacking surface direction by sandwiching a part of the article to be packed, it is preferable to use an elastic body such as a rubber material.

(Cut) The cut in the present invention is formed by cutting a sheet-like packing material or a packing box. By bending the cut portion inward and sandwiching it between the objects to be packed, it functions as a cushioning material and also functions as a fixing material.

In addition, the area of the cut portion can be enlarged, reduced, shortened vertically or horizontally, or lengthened in accordance with the shape of the article to be packed, as long as the function as the cushioning material is not impaired. The shape and size of the cut portion can be freely changed.

Further, by freely changing the shape and size of the cut portion, for example, the cut portion can be sandwiched so as to avoid a portion where contact with the packaged object is desired to be avoided. The portions that are desired to avoid contact with the packaged object include portions that are sensitive to dirt such as the light receiving surface of the solar cell module and do not want to be subjected to mechanical stress, and protrusions such as an output terminal box. And by making the shape of the cut portion a shape that does not come into contact with the light receiving surface, the protrusion, or the like, it is possible to prevent the attachment of minute dirt and the application of an extra load, and to reduce the entire packaging volume. .

(Packaged Article) The packaged article in the present invention is:
It is preferable that the cut portion has a substantially plate-like shape after maintaining the strength for sufficiently performing its function.
Although various examples such as those relating to buildings and those relating to mechanical devices can be given, a solar cell module is an example of a packaged object suitable for packaging according to the present invention.

More specifically, a plate-shaped aluminum frame type solar cell module having a rectangular cross section in the width direction and a plate-shaped roof tile rod having a cross section having a U-shape in the width direction. A solar cell module and a plate-shaped roofing type solar cell module having a plate-like roof having a cross-sectional shape of “S” in the width direction can be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings, but the present invention is not limited to these embodiments.

[Embodiment 1] FIG. 1 is an exploded perspective view showing a package of the first embodiment, and FIG. 2 is a cross-sectional view showing a packed state of the package of the first embodiment. As shown in the figure, the packing body of the present embodiment includes a packing box 1 made of cardboard and a packing material 2 made of cardboard having a cutout portion 3 which can be bent in part. A substantially plate-shaped aluminum frame type solar cell module 4 as an object to be packed is packed.

The packaging material 2 having bendable cut portions 3 is very easy to manufacture because it only cuts flat cardboard. In the packed state, the cut portion 3 is bent inward and is sandwiched by the aluminum frame type solar cell module 4 as an object to be packed, and functions as a cushioning material.

At the time of packing, first, two packing materials 2 each having a cutout portion 3 which can be partially bent are fitted along the opposing inner surfaces of the packing box 1. Then, when one aluminum frame type solar cell module 4 as an article to be packed is inserted, the cut portion 3 of a portion sandwiched between the next solar cell module 4 is bent, and the next solar cell module 4 is inserted. Since the main body of the packing material 2 is sandwiched between the packing box 1 and the solar cell module 4 and the cut portion 3 is sandwiched between the two solar cell modules 4, the packing material 2
Does not need to be fixed in the packing box 1 by another method beforehand.
It can be easily fixed only by considering the dimensions of the packing box 1, the packing material 2, and the cutout portion 3. By repeating such operations, a predetermined number of items to be packed 4 can be easily packed.

The cuts on one cut may be arranged vertically or may be shifted laterally, but the strength of the packing material 2 used after the cut is used. In consideration of the above, it is desirable that the distance between the cut portions is maintained at a certain value or more. In this embodiment, the packing material 2
Are made of corrugated cardboard, the size of the substantially plate-shaped aluminum frame type solar cell module 4 as a packaged object, the required area of the notch 3, etc. Is provided.

At the time of storage and transportation after packing, the cutout portion 3 functions as a cushioning material. Further, since the notch 3 is merely formed by bending and remains connected to the packing material 2, the notch 3 also has a function of preventing the notch 3 as a cushioning material from being displaced.

At the time of unpacking, it is only necessary to take out the solar cell modules 4 in order from the top, and the workability is very good.

At the time of disposal, both the packing box 1 and the packing material 2 are formed of corrugated cardboard, and the amount of use thereof is small, so that the burden on the environment is small. When collecting the packing box 1 and the packing material 2, the packing material 2 can be easily returned to a flat body by bending back the cut portion 3, and can be collected in a compact size.

The cut portion 3 can be reduced in area or devised in shape as long as the function of the cushioning material is not impaired. In the case of the present embodiment, the packaged object 5 is a substantially plate-shaped aluminum frame type solar cell module having a substantially “square” cross-section in the width direction. And a solar cell light receiving surface that is a power generation unit. The light receiving surface is desirably prevented from adhering dirt for the purpose of the power generation unit, and is often relatively weaker than the aluminum frame as the holding body. Therefore, the notch 3
By setting the shape so that it does not contact the light receiving surface, it is possible to easily prevent dirt from adhering to the light receiving surface and to apply extra pressure, which is more desirable.

[Embodiment 2] FIG. 3 is a sectional view showing a packing state of a packing body of Embodiment 2. As shown
The package of the present embodiment includes a cardboard packaging box 1 and a cardboard packaging material 2 having a partially bendable cut portion 3. The roof tile-type solar cell module 5 having a generally plate-like shape having a cross-sectional shape in the width direction substantially “U-shaped” is packed. That is, using a package similar to that of the first embodiment,
The roof tile-type solar cell module 5 having a generally plate-like shape having a cross-sectional shape in the width direction as a packaged object having a substantially “U-shape” is packed.

Roof tile type solar cell module 5 for roof
Has a solar cell light receiving surface on the lower surface in FIG. 3,
An output terminal box 6 is provided on the back surface, that is, on the upper surface in FIG.

As in the case of the first embodiment, in the packed state, the cut portion 3 is bent inward, and is sandwiched between the roof tile type solar cell modules 5 as the articles 5 to be packed.
It functions as a cushioning material.

At the time of packing, first, two packing boxes 2 each having a bendable cut portion 3 are fitted along the opposing inner surfaces of the packing box 1. Then, when one roof tile type solar cell module 5 as the article to be packed is inserted, the cut portion 3 of a portion sandwiched between the next solar cell module 5 is bent, and the next solar cell module 5 is inserted. . Since the main body of the packing material 2 is sandwiched between the packing box 1 and the solar cell module 5, and the cutout portion 3 is sandwiched between the two solar cell modules 5, the packing material 2 is previously packed by another method. Even if it is not fixed inside 1, it can be easily fixed only by considering the dimensions of the packing box 1, the packing material 2 and the cutout portion 3. By repeating such operations sequentially, a predetermined number of items to be packed 5 can be easily packed.

Here, the article to be packed is a roofing tile type solar cell module 5 having a generally plate-like shape whose cross section in the width direction has a substantially U-shape, and a projection called an output terminal box 6 is provided on the back surface. However, the notch 3 is smaller than the area of the lamination surface of the packaged object 5 and can have a shape that does not contact the output terminal box 6. Therefore, the stacking can be easily performed while saving the space corresponding to the height of the output terminal box 6, and the stacking can be performed very compactly in the height direction.

In this embodiment, in order to protect the output terminal box 6 of the uppermost solar cell module, another auxiliary cushioning material 7 is attached and packed at the end.

The notch 3 functions as a cushioning material during storage and transportation after packing. Further, since the notch 3 is merely formed by bending and remains connected to the packing material 2, the notch 3 also has a function of preventing the notch 3 as a cushioning material from being displaced. That is,
The object to be packed is a roofing tile type solar cell module 5 having a generally plate-shaped roof with a cross-section in the width direction of approximately "U-shaped". The contact area at the time of stacking is small, but the collapse of the load nevertheless. This can be prevented very efficiently.

The notch 3 is in contact only with the end, which is the mounting portion when the roof is installed, and the bent portion. Pressure can be easily prevented from being applied.

[Embodiment 3] FIG. 4 is a sectional view showing a packing state of a packing body of Embodiment 3. As shown
The packing body of the present embodiment is a packing box 1 made of corrugated cardboard and a packing material 2 made of rubber having a cutout portion 3 which can be bent partially.
By using the package, a roughly plate-shaped roofing tile type solar cell module 5 having a cross-sectional shape in the width direction as an object to be packed having an approximate “U-shape” is packed. I have. That is, a packing body similar to that of the second embodiment is used, and a rubber member is used as the packing material 2 having the cut portion 3 for packing.

The packing material 2 having the cutouts 3 is very easy to manufacture because only a flat rubber member is cut. As in the case of the second embodiment, in the packed state, the cut portion 3 is bent inward and is sandwiched between roof tile type solar cell modules 5 as an object to be packed, and functions as a cushioning material.

At the time of packing, first, two rubber packages 2 each having a cutout portion 3 which can be partially bent are fitted along opposing inner surfaces of the cardboard box 1. Then, when one roof tile type solar cell module 5 as the article to be packed is inserted, the cut portion 3 of a portion sandwiched between the next solar cell module 5 is bent, and the next solar cell module 5 is inserted. . Packing material 2 is packing box 1
Notch 3 between the solar cell module 5 and
Is sandwiched between the two photovoltaic modules 5, so that the dimensions of the packing box 1, the packing material 2 and the cutout 3 are taken into consideration without having to fix the packing material 2 in the packing box 1 by another method in advance. It can be easily fixed simply by keeping it. By repeating such operations sequentially, a predetermined number of items to be packed 5 can be easily packed.

Here, the packing material 2 is made of rubber, and the bent portion at the end of the roof tile type solar cell module 5 is formed on the rising surface of the packing material 2 because of the elasticity of the rubber member. And the notch 3, and is more strongly fixed in the direction of the lamination surface.

In this embodiment, in order to protect the output terminal box 6 of the uppermost solar cell module, another auxiliary cushioning material 7 is finally mounted for packing.

The cut portion 3 functions as a cushioning material during storage and transportation after packing. In addition, the upright surface of the packing material 2 and the cut portion 3 function as a fixing material for preventing displacement in the stacking surface direction. If transportation conditions are more stringent,
For example, in the case where transportation must be performed under the condition of severe lateral vibration, the configuration of this embodiment can reduce the force of the packaged object to shift in position (lateral shift). It is more effective as a countermeasure against damage.

At the time of unpacking, it is only necessary to take out the solar cell modules in order from the top, and the workability is very good.

At the time of disposal, both the packing box 1 and the packing material 2 use a small amount, and the load on the environment is small. When collecting the packing box 1 and the packing material 2, the packing material 2 can be easily returned to a flat body by bending back the cut portion 3, and can be collected in a compact size.

[Embodiment 4] FIG. 5 is a sectional view showing a packing state of a packing body of Embodiment 4. As shown
The package of the present embodiment includes a cardboard packaging box 1 and a cardboard packaging material 2 having a partially bendable cut portion 3. In this example, a substantially plate-like roofing type solar cell module 8 for a roof having a cross-sectional shape in the width direction that is substantially “S-shaped” is packed.

Horizontal roof type solar cell module 8 for roof
Has an approximately "S-shaped" cross-sectional shape that is bent in opposite directions at both ends in the width direction, and has a parallel surface that has been bent twice at 90 degrees. Since the horizontal roofing type solar cell module 8 for a roof is relatively narrow and long in the longitudinal direction, in this embodiment, the amount of the packaging material used is further reduced, and a single cardboard packaging is used. It is arranged in two vertical rows in the box 1 and packed. In addition, auxiliary cushioning members 7 were set at the lowermost and uppermost portions so that the load at the time of lamination was evenly applied to the parallel surface of the "S-shaped" portion, and the package was packed so that the parallel surface was horizontal.

As in the case of the first embodiment, in the packed state, the cut portion 3 is bent inward and is sandwiched by the roofing type solar cell module 8 as a packaged object and functions as a cushioning material.

At the time of packing, first, two packing materials 2 each having a notch 3 which can be partially bent along opposing inner surfaces of the packing box 1, and one packing material 2 in the center of these two packing materials,
Two auxiliary cushioning members 7 are fitted. Since the cut portions 3 of the packing material 2 at the center need to be bent to both sides, the cut portions 3 are arranged so as to be appropriately shifted laterally while increasing the number and considering the strength. The auxiliary cushioning member 7 is fixed using another method. Then, when two roofing type solar cell modules 8 for the roof as the article to be packed are inserted, the cutout portion 3 of the portion sandwiched between the next solar cell module 8 is bent,
The next solar cell module 8 is inserted.

The packing material 2 is sandwiched between the packing box 1 and the solar cell module 8 or between the two solar cell modules 8, and the cut portion 3 is sandwiched between the two solar cell modules 8. Material 2 is packed in a different way in advance.
Even if it is not fixed inside, it can be easily fixed only by considering the dimensions of the packing box 1, the packing material 2, and the cutout portion 3. By repeating such operations sequentially, a predetermined number of items to be packed 8 can be easily packed.

Here, the article to be packaged is a roofing type solar cell module 8 for a roof having a generally plate-like shape having a cross section in the width direction having an approximate “S” shape, and having two parallel surfaces in a bent portion. ing. Considering how the load is applied during lamination, it is desirable that the load be received not only at the end of the bent portion of the "S shape" but at the parallel plane of the bent portion. Even in such a case, according to the present invention, the cut portion 3 can be formed to have a shape smaller than the area of the stacking surface of the packaged article and to contact only the parallel surface. For this reason, it is possible to easily laminate the parallel surfaces in a horizontal plane. In other words, for example, the notch bending part 3
a and the cut-and-bent portion 3b are separated from each other, so that the solar cell modules 8a can be easily stacked in such a manner that the parallel surfaces at the ends are horizontal.

In this embodiment, for the purpose of fixing the upper part of the uppermost solar cell module, another auxiliary cushioning material 7 is finally attached and packed.

[Fifth Embodiment] FIG. 6 is an exploded perspective view showing a package of a fifth embodiment. As shown in the figure, the package of the present embodiment has a packaging box 1 and a cutout 3
And the packing material is packed using the packing body.

The packaging material 2 having a cut portion 3 which can be bent in a part thereof is very easy to manufacture because only a flat member is cut. In the packing state,
The cut portion 3 is bent inward and is sandwiched between the objects to be packed, and functions as a cushioning material.

At the time of packing, firstly, two packing materials 2 each having a cutout portion 3 which can be partially bent along the opposing inner side surfaces of the packing box 1 are fitted into each of the four packing materials. That is, in the present embodiment, the packing material 2 made of the cardboard in the first embodiment is used.
Corresponds to a mode in which the amount of the packaging material 2 used is further reduced by omitting the central portion of the package. Each of the packing materials 2 qualitatively has a tendency to easily cause a lateral displacement because the central portion of the packing material 2 of the first embodiment is omitted. Weight, packing box 1, packing material 2
If the dimensions and properties of the cutout 3 are sufficiently considered, the cutout 3 can be easily fixed.

When the objects to be packed are taken out from the upper part at the time of unpacking, since the central portion of the packing material 2 of the first embodiment is omitted, it is assumed that the members forming the packing box 1 are made of a material which is hardly bent. Also, there is a space for handling in that part, and the workability is further improved irrespective of the shape of the article to be packed.

At the time of disposal, both the packaging box 1 and the packaging material 2 use a small amount, and the burden on the environment is small.

[Embodiment 6] FIG. 7 is an exploded perspective view showing a package according to a sixth embodiment, and FIG. 8 is a sectional view showing a package state of the package according to the sixth embodiment. As shown in the figure, the package of the present embodiment is composed of a cardboard packaging box 9 having a cutout portion 3 that can be partially bent, and using the package, a general plate as an object to be packed. The aluminum frame type solar cell module 4 is packed in a shape.

The cardboard packaging box 9 having the bendable cutouts 3 in a part thereof is very easy to manufacture, since only a normal corrugated cardboard packaging box is cut. In the packed state, the cut portion 3 is bent and sandwiched by the aluminum frame type solar power module 4 as an object to be packed, and functions as a cushioning material.

At the time of packing, when one aluminum frame type solar cell module 4 as an object to be packed is put in the packing box 9, the cut portion 3 of the portion sandwiched between the next solar cell module 4 is bent, and Insert 4 solar cell modules. By repeating such operations sequentially, a predetermined number of items to be packed 4 can be easily packed.

The cut portions above one cut portion may be arranged vertically or may be shifted horizontally, but the strength of the material of the packing box 9 used after the cut process is performed. In consideration of the above, it is desirable that the distance between the cut portions is maintained at a certain value or more. In this embodiment, in consideration of the fact that the packing box 9 is made of corrugated cardboard, the size of the aluminum frame type solar cell module 4 to be packed, the required area of the notch 3, etc. A row notch 3 is provided.

Further, making a cut in the cardboard packaging box 9 qualitatively tends to reduce the strength of the packaging box 9, but in practice, the packaged object itself has some strength. The necessary strength can be ensured if the strength of the object to be packed is also utilized and the strength of the whole after packing is sufficiently considered.

The notch 3 functions as a cushioning material during storage and transportation after packing. Further, since the notch 3 is merely bent and remains connected to the packing box 9, the notch 3 also has a function of preventing the notch 3 as a cushioning material from being displaced.

At the time of unpacking, it is only necessary to take out the solar cell modules in order from the top, and the workability is very good. In addition, since the packing box itself has a cut portion and is bent and formed in the packed state, the packaged object 4 in the packing box can be easily formed.
You can check the number of stock.

At the time of disposal, the packing box 9 is made of corrugated cardboard, the amount of use is small, and the load on the environment is small. When collecting the packing box 9, the side surface of the packing box 9 can be easily returned to a flat body by bending back the notch 3, so that the packing box 9 can be made compact and collected.

As described above, according to the present invention,
A notch is provided in the packing material, and the notch is bent at the time of packing to function as a cushioning material between objects to be packed. Alternatively, it functions as a fixing material for the article to be packed.

As a result, while satisfying the functions such as safe storage and transportation of the packaged objects, the amount of packing materials used is reduced, and the degree of freedom in selecting the packing materials is increased. The cost and the load of disposal can be reduced, and when it is reused, it can be easily collected, and a package having good workability at the time of packing and unpacking can be provided.
