[ detailed description ] embodiments

Embodiments of the present invention will be described below with reference to the drawings. The following description relates to an example of the present invention, and the present invention is not limited to this.

Fig. 1 shows a package 1 according to an embodiment of the present invention. In the present embodiment, the package body 1 is a rectangular parallelepiped. The package body 1 is housed in the package case 7. The package assembly according to one embodiment of the present application includes a package body 1 and a package case 7 that houses the package body 1.

The packing box 7 is, for example, a corrugated box (ダンボール box). For example, it is preferable to dispose a reinforcing plate on the inner side surface (4 side surfaces, bottom surface, and top surface) of the packing case 7 and dispose a reinforcing plate between the packing case 7 and the package body 1. As the reinforcing plate, a wood plate, a paper compression plate, a foamed plastic plate, or the like can be used. When the packing case 7 in which the reinforcing plate is disposed between the packing case 7 and the packing body 1 is used, the packing body 1 can be protected from external force. In addition, a reinforcing plate may be joined between the package body 1 and a part or all of one or more inner side surfaces of the package case 7. Further, a cushioning material such as an elastic body or a bubble cushioning material may be provided between the package body 1 and a part or all of one or more inner side surfaces of the package box 7. In this case, the reinforcing plate may be omitted. With such a configuration, the package body 1 can be protected from external force.

When the packing box 7 is a corrugated cardboard box, the packing box 7 is composed of a liner (top ライナー), a liner (inner ライナー), and a corrugated core liner (center ライナー). The core liner is between the face liner and the liner, and is joined to the face liner and the liner. The height of the layer (section) of the packing box 7 (the distance between the surface liner and the back liner) is, for example, 0.5mm to 5mm, preferably 1.5mm to 5 mm. In addition, every 1m²The mass of the surface liner and the back liner is, for example, 100g to 300g, preferably 150g to 280 g. Every 1m²The mass of the core liner is, for example, 100g to 200g, preferably 120g to 180 g. In addition, from the viewpoint of improving the cushioning property, the compressive strength, and the breaking strength, a W-layer corrugated carton in which 2 layers having different layer heights are stacked may be used. In this case, it is preferable to use a W-layer corrugated paper in which a layer having a layer height of 3mm and a layer having a layer height of 5mm are combined.

As shown in fig. 2(a) and (b), the package body 1 includes: a plurality of (10 in the figure) layered bodies 5 in a standing state, and a packing container 2 for packing the layered bodies 5. In the present embodiment, the layered bodies 5 are arranged in two rows of 5 pieces per row, but the layered bodies 5 do not necessarily have to be arranged in two rows. For example, the layered body 5 may be arranged in one row, or may be arranged in three or more rows. Alternatively, the packaging container 2 may be configured such that only 1 of the layered bodies 5 is wrapped inside.

As shown in fig. 4, each laminate 5 includes 2 or more brittle thin sheet materials 50. The laminate 5 is held by a bag-shaped laminate holding member 6, for example. The laminate holding member 6 may be any article in a laminated state capable of holding the laminate 5 in a state in which 2 or more brittle thin sheet materials 50 are not separated. For example, the shape may be an envelope shape in which two sides of a rectangular shape are joined at three sides, or a folder (ファイル) shape in which two adjacent sides or two opposite sides are joined. The thickness of one surface is, for example, 0.03 to 1.5mm, preferably 0.04 to 1.0mm, and more preferably 0.04 to 0.5 mm. For example, in the case where the laminate holding material 6 is in the shape of an envelope, after the laminate 5 is inserted into the laminate holding material 6, one side and four corners of the opening side are folded back in a triangular shape so that the entire laminate holding material 6 is in close contact with the laminate 5, and are fixed with an adhesive tape. Thereby, the laminated body 5 is held and the laminated state of the brittle thin sheet material 50 is maintained. The laminate holding member 6 may be formed of a packaging film for holding the laminate 5. In this case, the inside of the packaging film as the laminate holding material 6 may be continuously decompressed and subjected to vacuum packaging or vacuum packaging. Further, in this case, a sugar pack (キャラメル pack), a shrink pack (シュリンク pack), a pack based on an OPP (biaxially oriented polypropylene) bag, or the like may be used.

The laminated body 5 can be formed by laminating only the brittle thin sheet material 50, but is not limited thereto. For example, as shown in fig. 5, a spacer 51 such as paper, sheet-like sponge, or polyethylene sheet may be disposed between the brittle thin sheets 50. In this case, the holding material may be formed in a booklet shape (formed by binding り) in which one side of 2 or more spacers 51 are joined to each other. Further, a cushion material may be attached to at least a part of the outer surface of the laminated body 5.

The laminate holding member 6 is not limited to the bag-shaped article. For example, as shown in fig. 6, the laminate holding member may be a single sheet 63 for wrapping the laminate 5. As shown in fig. 7, the laminate holding member may be a tape 61 surrounding 2 sets of side surfaces of the laminates 5 facing each other. Further, as shown in fig. 8, the laminated body holding material may be composed of 2 sheets 65A and 65C covering both surfaces of the laminated body 5 in the laminating direction, and a connecting portion 65B connecting the sheets 65A and 65C. In this case, one side of the spacer 51 disposed between the brittle thin plates 50 may be joined to the connecting portion 65B. Among them, the laminate holding member 6 is preferably configured to cover the entire laminate 5 in order to improve the protection of the laminate 5. Particularly, the laminate holding member 6 is preferably in the form of a bag covering the entire laminate 5.

The material of the bag-like layered body holding member 6 is not particularly limited, and a bag having a non-charging property is preferably used in terms of preventing adhesion of dust. Among them, it may be made of polyethylene or polypropylene. Here, the term "non-charging property" means that the surface resistivity is 10 under the conditions of 20 ℃ and 15% RH¹⁰Omega/□ or less, preferably 10⁹Omega/□ or less.

The number of the brittle thin sheet materials 50 constituting 1 laminate 5 is, for example, about 5 to 500, preferably about 10 to 200. Further, the brittle thin plate materials 50 may be directly laminated to each other inside the laminated body holding member 6, or the brittle thin plate materials 5 may be stored in separate bags for each sheet or for each 2 or more sheets. In the case where the brittle thin plate material 5 is a structure in which the front surface and the back surface are made of different materials as described later, the brittle thin plate materials 5 may be stacked while being alternately inverted so that the same surfaces face each other, or the brittle thin plate materials 5 may be stacked in the same orientation so that the different surfaces face each other.

The brittle sheet material 50 is a thin and brittle sheet material that may be broken, chipped (under け), or deformed during packaging or transportation, and a typical example thereof is a thin-sheet-like ceramic molded body. For example, as a thin plate-like ceramic molded body, there are the following molded bodies: a dense body used for an electronic circuit substrate, an electrolyte sheet or a separator plate of a Solid Oxide Fuel Cell (SOFC), or the like; porous materials used for electrodes of SOFC and the like; a structure body formed by combining more than 2 compact bodies; a structure body in which a dense body and a porous body are combined; a structure in which porous bodies are arranged on both sides of a dense body (for example, a cell of a fuel cell), a structure in which 2 or more porous bodies are combined, or the like.

As a material of the dense body used in the electronic circuit substrate, alumina, zirconia, aluminum nitride, mullite, cordierite, a mixture of alumina/borosilicate glass, a mixture of cordierite/borosilicate glass, or the like can be used.

As the material of the dense body used in the electrolyte sheet for the electrolyte-supported cell of the SOFC, there can be used: stabilized zirconia to which an oxide of a rare earth element, an alkaline earth element, or the like is added; LaGaO₃、LaSrGaMgO₃Isogallium acid lanthanide series perovskite type composite oxides; and cerium-based composite oxides such as gadolinium-doped cerium and samarium oxide-doped cerium.

Specific examples of stabilized zirconia are: zirconia stabilized by 3 to 15 mol% of yttrium trioxide; zirconia stabilized with 3 to 15 mol% scandia; zirconia stabilized with 3 to 15 mol% of ytterbium oxide; zirconia stabilized with 8-12 mol% scandia, 0.5-3 mol% ceria; zirconia stabilized with 3 to 15 mol% of yttria and scandia (wherein 0 mol% < yttria and scandia ≦ 15 mol%), and the like.

As a material of the dense body used for the separation plate of SOFC, LaCrO can be used₃、LaCaCrO₃、LaSrCrO₃And lanthanum chromite perovskite composite oxides.

As the material of the porous body used for the fuel electrode substrate for the fuel electrode-supporting cell of the SOFC, a mixture of nickel oxide/the stabilized zirconia, a mixture of nickel oxide/the ceria-based composite oxide, a mixture of nickel oxide/the stabilized zirconia/the ceria-based composite oxide, or the like can be used.

LaCoO can be used as a material of a porous body used for an air electrode substrate for an air electrode-supported cell of an SOFC₃、LaSrCoO₃、LaMnO₃、LaSrMnO₃、LaNiFeO₃A perovskite-type or other composite oxide, a mixture of the perovskite-type composite oxide and the stabilized zirconia, the perovskite-type composite oxide and the ceria-based composite oxide, and the perovskite-type composite oxideA mixture of the stabilized zirconia/the ceria-based composite oxide, and the like.

The above materials may be used alone, or 2 or more kinds may be appropriately combined as necessary.

The shape of the brittle thin sheet material 50 is not particularly limited, and may be any of a circular shape, an oval shape, a rectangular shape with rounded corners, and the like. Alternatively, the brittle thin plate material 50 may have a shape having a hole for gas flow, for example, a doughnut shape. Further, grooves for scribing (スクライブ) or wavy irregularities may be formed on the surface of the brittle sheet material 50.

The outer area (area defined by outline and not related to the presence or absence of the hole) of the brittle thin plate material 50 is, for example, 25cm²Above 1000cm²The following. The outer area of the brittle sheet material 50 is preferably 50cm²Above 900cm²Below, more preferably 80cm²Above 600cm²The following.

The thickness of the brittle thin sheet material 50 is, for example, 0.03mm to 0.5 mm. The thickness of the brittle thin sheet material 50 is preferably 0.1mm to 0.3mm, more preferably 0.12mm to 0.25 mm.

When the brittle sheet material 50 is an alumina-based material, the outer area of the brittle sheet material 50 is preferably 25cm²Above 250cm²Below, more preferably 30cm²Above 150cm²Less than, more preferably 50cm²Above 100cm²The following. The thickness of the brittle thin sheet material 50 is preferably 0.1mm to 0.5mm, more preferably 0.12mm to 0.45mm, and still more preferably 0.15mm to 0.4 mm.

When the brittle thin sheet material 50 is a zirconia-based material, the outer area of the brittle thin sheet material 50 is preferably 50cm²Above 1000cm²Below, more preferably 80cm²Above 900cm²Hereinafter, more preferably 100cm²Above 600cm²The following. The thickness of the brittle thin sheet material 50 is preferably 0.03mm to 0.45mm, more preferably 0.05mm to 0.4mm, and still more preferably 0.1mm to 0.35 mm.

The material of the packaging container 2 is not particularly limited, and at least a part of the packaging container 2 may be a foam. For example, polystyrene having a low cost can be used as a material constituting the foam. Among them, reinforced polypropylene may be used in view of the strength of the packaging container 2. As a material constituting the foam, polyurethane can be used. For example, in the packaging container 2, the concave portion 41 of the main body portion 4 and the lid portion 3 in contact with the layered body 5 or the layered body holding member 6 may be formed of a foamed material. The packaging container 2 may be formed of a corrugated cardboard box, a paper-made compressed sheet, or the like. Further, the packing container 2 may be provided with projections and recesses on the outer surface thereof.

When at least a part of the packaging container 2 is a foam, the foam has a foaming ratio of preferably 10 to 90 times, more preferably 20 to 80 times, and further preferably 30 to 70 times, from the viewpoint of cushioning properties with respect to the brittle thin sheet material. Also, the foams need not all be of the same expansion ratio. For example, the foaming magnification of the foam may be 40 to 90 times, preferably 50 to 80 times, in the recess 41 of the main body 4 and the lid 3 in contact with the laminate 5 or the laminate holding material 6, and the foaming magnification of the foam may be 10 to 60 times, preferably 20 to 50 times, in the other portions. Here, the expansion ratio is the reciprocal of the bulk density, and means the volume per unit mass, which is the unit of volume/mass. In this specification, the unit is not used and is denoted as "multiple".

The main body 4 has 2 or more recesses 41 (10 in fig. 3 (b)). The respective laminate 5 is fitted into the recess 41 together with the laminate holding member 6. For example, the respective laminated bodies 5 may be fitted into the recessed portion 41 together with the laminated body holding member 6 in a state where the surface of the laminated body 5 formed in the laminating direction faces the bottom surface of the recessed portion 41. In the present embodiment, the depth of the recess 41 is smaller than the length of one side of the brittle thin plate material 50, and the upper portion of the layered body 5 in the standing state protrudes from the main body 4.

The recess 41 has substantially the same shape as the lower portion of the vertically arranged laminated body 5. That is, the width of the recess 41 is slightly larger than the other side of the brittle thin plate material, and the depth of the recess 41 is slightly larger than the thickness of the laminated body 5. Therefore, when the layered body 5 is fitted into the recess 41 together with the package 6, it is held in this state. Here, a pair of surfaces of the layered body 5 facing each other with the center of the layered body 5 interposed therebetween is preferably fixed by the concave portion 41. In this case, it is preferable that a pair of surfaces of the laminated body 5 opposed to each other with the laminated body 5 interposed therebetween in the laminating direction be fixed by the concave portion 41. This reduces the possibility of breakage of the brittle thin sheet material due to vibration during transportation of the package body 1. The center of the laminate 5 is a midpoint of a line segment connecting the center of the surface of the brittle thin sheet material 50 disposed at one end of the laminate 5 and the center of the surface of the brittle thin sheet material 50 disposed at the other end of the laminate 5.

The distance D1 (see fig. 3(b)) between the adjacent recesses 41 in the stacking direction of the stacked body 5 may be determined as appropriate according to the size of the stacked body 5, and may be 20mm or less, but is preferably 10mm or less, more preferably 8mm or less, and still more preferably 6mm or less, from the viewpoint of downsizing of the packaging container 2. In view of protecting the laminate 5, the distance D between the recesses 41 is, for example, 1mm or more, preferably 2mm or more.

The package body 1 further includes a lid portion 3 covering the integrated body 5 above the recess 41. The lid 3 covers the integrated body 5 above the main body 4. In the present embodiment, the lid 3 is also provided with a recess 31 into which the laminated body 5 and the laminated body support member 6 are fitted. Here, it is preferable that a pair of surfaces of the laminated body 5 opposed to each other with the center of the laminated body 5 interposed therebetween in the laminating direction is fixed by the recess 41 and the lid 3. In other words, the end surfaces of the layered body 5 facing each other with the center of the layered body 5 interposed therebetween are preferably fixed by the recess 41 and the lid 3. This can prevent the layered body 5 from moving and colliding with the packaging container 2 during transportation or the like. Therefore, the possibility of breakage of the brittle thin sheet material 50 can be reduced. As shown in fig. 9, a relatively large recess 35 may be provided in the cover part 3 to surround the upper part of the entire layered body 5. In this case, the laminated body 5 is pressed into the recess 41 by the bottom surface of the recess 35. Alternatively, when the depth of the recess 41 of the main body 4 is slightly larger than the length of one side of the brittle thin plate material 50, the cover 3 may be flat. In this case, the gap between the laminated body 5 and the lid 3 is filled with a spacer or the like containing a cushion material, so that the laminated body 5 can be pressed into the recess 41 by the lid 3. The laminate holding material 6 may also serve as the spacer. Further, the upper surface of the packing box 7 may also have the lid 3. Further, the cover may have 2 or more covers covering one or 2 or more recesses 41.

As shown in fig. 10, the concave portion 41 may be formed obliquely. With this configuration, the height of the packaging container 2 can be suppressed.

As shown in fig. 11, the depth of the recess 41 provided in the main body 4 may be larger than the length of one side of the brittle thin plate material 50. In this case, the cover 3 may further have a convex portion 37 fitted into the concave portion 41. Thereby, the laminated body 50 can be pressed into the concave portion 41 by the convex portion 37 of the cover portion 3. Further, since the layered body 50 is held at a position away from the outside of the packing container 2, an impact from the outside can be reduced.

The relationship between the height of the main body 4 and the height of the lid 3 is not particularly limited. The height of the body portion 4 may be greater than the height of the cover portion 3, and the height of the cover portion 3 may also be greater than the height of the body portion 4. The height of the body portion 4 and the height of the lid portion 3 may be the same. In order to protect the integrated body 5 with a deeper recess, one of the height of the body portion 4 and the height of the lid portion 3 is preferably larger than the other.

As shown in fig. 3(a), a peripheral wall 32 having a rectangular tubular shape is formed at the periphery of the lower surface of the lid 3. On the other hand, as shown in fig. 3(b), a step portion 42 for fitting into the peripheral wall 32 is formed in the peripheral portion of the upper surface of the main body portion 4. A recess may be formed in the peripheral wall 32, and a projection may be formed in the step 42 to engage with the recess. Further, a concave portion may be formed in the step portion 42, and a convex portion that engages with the concave portion may be formed in the peripheral wall 32. By engaging the convex portion with the concave portion, the lid portion 3 is not easily separated from the main body portion 4.

As shown in fig. 12, the

projections

31A and 41A may be formed on the side surface of the recess 31 of the lid portion 3 or the side surface of the recess 41 of the body portion 4. The pair of end faces of the laminate 5 facing each other with the center of the laminate 5 therebetween can be fixed by the

convex portions

31A and 41A. The shape of the convex portion is not particularly limited, and may be a corrugated shape in which the convex portion makes point-like contact with the laminate 5 or the laminate holding member 6. The shape of the convex portion may be a shape in linear contact with the laminate 5 or the laminate holding member 6. Further, the shape of the convex portion may be such that the surfaces in contact with the laminate 5 or the laminate holding member 6 are arranged intermittently.

Next, a method of forming the package body 1 will be explained.

First, as shown in fig. 4, a laminate 5 including 2 or more brittle thin plate materials 50 is held by a laminate holding member 6. For example, the laminated body 5 is accommodated in a bag-shaped laminated body holding material 6. In this case, the laminate 5 is preferably sealed with the laminate holding member 6 as described above. Next, the surface of the layered body 5 formed in the stacking direction faces the bottom surface of the concave portion 41, and is fitted into 2 or more concave portions 41 of the main body portion 4 of the packaging container 2 together with the layered body holding member 6. Further, the lid 3 may be covered so as to cover the laminated body 5 above the recess 41. Thereby, the laminated body 5 is covered with the lid 3. In the present embodiment, this operation can be performed while inserting the layered body 5 into the recess 31 of the lid 3. Thereby forming the package body 1.

The formed package body 1 can be directly stacked on a transportation pallet (パレット), but is preferably stored in a package box 7 having a reinforcing plate joined to the inner surface as shown in fig. 1. This is because the deformation of the packing case 7 and the packing body 1 can be prevented even if the hook of the forklift hits the packing case 7 without any attention.

Fig. 13 shows a packing container 2 according to another embodiment of the present invention. The lid 3 is a box-shaped body having one open surface. On the other hand, the main body 4 includes a

base portion

45 and 2 or more spaced portions 47 arranged in a row on the base portion 4. Then, the side surfaces of the adjacent spacers 47 and the base portion 45 form a recess 49. The laminate 5 is fitted into the recess 49 together with the laminate holding member 6. In the main body 4, a step portion 45A is formed at the peripheral end of the base portion 45 so as to surround the base portion 45. The lid 3 is attached to the main body 4 so that the open end 39 of the lid 3 fits in the step 45A, and the integrated body 5 is covered above the main body 4. In this case, the bottom surface of the cover 3 presses the laminated body 50 against the base portion 45 forming a part of the recess 49. This allows the layered body 5 to be held in the packaging container 2.

In fig. 13, 2 or more spacers 47 may be arranged in 2 rows so as to form 2 rows of recesses 49, or may be arranged in one row, or may be arranged in 3 rows or more. In addition, 2 or more spacers 47 may be provided so as to form at least 1 recess 49. The range of the interval D2 between the concave portions 49 (the thickness of the spacer 47) is the same as the range of the interval D1 between the concave portions 41.

In the package 1 of the present embodiment described above, the brittle thin-film sheet 50 can be protected by the packaging container 2 and the laminate holding member 6, and thus the brittle thin-film sheet 50 can be prevented from being damaged.

In particular, when the brittle thin sheet material 50 is a zirconia-based material, the effect of significantly suppressing the occurrence of "chipping", "cracking (ヒビ)", and "indentation (へこみ)" on the end surface or the flat surface of the brittle thin sheet material 50, which is particularly likely to be broken, is obtained.

[ examples ] A method for producing a compound

Next, the technical means of the present application will be described in detail by examples. However, the following examples are merely examples of the present invention, and the present invention is not limited to the following examples.

(free fall test)

First, the evaluation methods of examples and comparative examples will be described. The package bodies or package aggregates of examples and comparative examples were allowed to freely fall from a position having a height of 60cm onto the floor so that the falling posture was a surface fall (surface fall) in accordance with JIS (japanese industrial standards) Z0202-1994. The structure of the floor was a structure in which a urethane coating was applied to the concrete surface. After the test, with respect to all the 8YSZ (zirconia stabilized with 8 mol% yttria) sheets contained in the package body or the package aggregate, breakage (breakage) of the sheets was visually confirmed. In addition, with respect to all of the 8YSZ sheets, "defects" and "cracks" on the surface were detected by the transmission type photoelectric sensor. The number of 8YSZ sheets in which breakage or defects were confirmed was divided by the total number of 8YSZ sheets tested, and the breakage rate and the defect occurrence rate were calculated.

(oblique impact test)

The package bodies or package assemblies of examples and comparative examples were placed on a carrier of a slide car on rails and inclined at an angle of 10 ° based on JIS Z0205-1998, and an oblique impact test was performed by hitting an impact plate from behind. After the test, the breakage (breakage) of the sheet was visually confirmed for all the 8YSZ sheets contained in the package or the package aggregate. In addition, with respect to all of the 8YSZ sheets, "defects" and "cracks" on the surface were detected by the transmission type photoelectric sensor. The number of 8YSZ sheets in which breakage or defects were confirmed was divided by the total number of 8YSZ sheets tested, and the breakage rate and the defect occurrence rate were calculated.

(example 1)

An 8YSZ sheet (manufactured by Nippon catalyst Co., Ltd.) having a square thickness of 120mm and a thickness of 120 μm was 125-ply-laminated, and the obtained laminate was packed in a commercially available non-chargeable polyethylene bag (thickness: 0.05mm, surface resistivity: 10) as a laminate holding material⁸Ω/□). The opening of the bag is sealed, and the periphery of the opening is folded back and bonded to the outer surface of the bag. In addition, four corners of the bag are folded into a triangular shape and bonded to the outer surface of the bag. Thereby holding the laminate in the laminate holding material. Next, 10 sets of the laminated bodies held in the laminated body holding material were stored in a polystyrene foam packing container having a foaming ratio of about 50 shown in fig. 1. Specifically, the stacked body is fitted into the concave portion of the packaging container body portion together with the stacked body holding member in a state where the stacking direction of the stacked body is horizontal, and the lid portion is covered from the upper surface. A pair of end portions (upper end and lower end) of the laminated body are fixed by the recess and the lid. Thus, a package of example 1 was produced.

Next, the package body described above was put into a packaging box shown in fig. 1, and a foamed styrene plate having a foaming magnification of about 30 times was inserted into the entire gap between the package body and the packaging box. The packing case is composed ofA W-layer corrugated carton formed by two layers of a layer of 5mm height and a layer of about 3mm height. In addition, every 1m²The corrugated liner board (ライナー) weighs about 180 grams. The package aggregate of example 1 was thus produced. As described above, the package and the package aggregate of example 1 were subjected to the free fall test and the oblique impact test. The results of the free fall test are shown in Table 1 and the results of the oblique impact test are shown in Table 2.

(example 2)

The 10 sets of laminates held by the laminate holding member prepared in the same manner as in example 1 were inserted into the recess of the main body of the polystyrene foam packaging container shown in fig. 1, and the lid portion was covered from the top. A pair of end portions of the laminated body are fixed by the recess and the cover. The packing container uses a foam having a main material expansion ratio of about 40. In addition, the packing container has the following structure: a foam sheet having a foaming magnification of 60 times is joined to the main material via an adhesive on the surface thereof that is in contact with the laminate holding material. Thus, a package of example 2 was produced.

The package described above was put into the packaging box shown in fig. 1, and a plywood (ベニヤ plywood) as a reinforcing plate was inserted into the entire gap between the package and the packaging box. In addition, the packing case has a layer height of about 3mm per 1m²The weight of the liner board is about 220g of corrugated carton. The package aggregate of example 2 was thus produced. Then, a free fall test and a tilt impact test were performed in the same manner as in example 1, and the total amount of the 8YSZ sheets stored therein was examined. The results of the free fall test are shown in Table 1 and the results of the oblique impact test are shown in Table 2.

Comparative example 1

The 8YSZ sheets were prepared into 10 sheet units, and held in a paper booklet-like storage material having a 120mm square planar shape as shown in fig. 8, to prepare a laminate of 250 8YSZ sheets. An end cushioning material was placed on the upper and lower surfaces of the laminate, and wound in a cross shape with a polypropylene tape (product name: P.P. tape 15mm wide, manufactured by waterlogging chemical Co., Ltd.) to be fastened and fixed, thereby obtaining a package. At this time, the surface pressure applied to the 8YSZ sheet was 200gf/cm². The end part buffer material is 151mm square,Thickness of 10mm and density of 0.086g/cm³The polyethylene foam (product name: SUNPELCA (サンベルカ) L1400, manufactured by Lysidi corporation (Hayashi Felt)) of (1) has a recess (recess shape: 122mm square, recess depth: 5mm) in the central portion thereof for accommodating both end portions of the laminate. Next, 4 packages were stored in commercially available non-chargeable bags. Further, the packages accommodated in the bags are respectively loaded into the disk-like cushioning and holding members so that the stacking direction of the stacked bodies is the longitudinal direction. Finally, it was housed in a transport container made of a load box (キャリングケース) made of duralumin (ジュラルミン). A gap between the transfer container and the package filled in the non-charging bag was filled with a polyethylene pad (クッション) (product name アスパックサラサラ manufactured by Asahi chemical Co., Ltd.). Thus, the package aggregate of comparative example 2 was produced. Next, the package aggregate was subjected to a free fall test and a tilt impact test in the same manner as in example 1, and the total amount of 1000 YS sheets contained therein was examined. The results of the free fall test are shown in Table 1 and the results of the oblique impact test are shown in Table 2.
