Abstract
Description
- The present invention relates to a package including brittle thin-sheet materials and to a package assembly containing the package. The present invention also relates to a packaging method for forming the package.
- Conventionally, when brittle thin-sheet materials such as ceramic sheets are transported or stored, measures to protect the brittle thin-sheet materials are taken. For example,
Patent Literature 1 discloses that a plurality of brittle thin-sheet materials 10 are put into aportion bag 11 as shown inFIG. 14B , the packs thus formed are arranged in an upright position in apackaging box 13 as shown inFIG. 14A , andbuffer members 12 are disposed on both sides of the arranged packs. The height of theportion bag 11 is smaller than the height of the brittle thin-sheet materials 10, and the upper parts of the brittle thin-sheet materials 10 are exposed from theportion bag 11. It is also disclosed that thepackaging boxes 13 containing the packs of the brittle thin-sheet materials 10 are held in tray-like buffering holders (omitted in the figures) in a transport container (omitted in the figures) in such a manner that the stacking direction of the brittle thin-sheet materials 10 coincides with the vertical direction. - Patent Literature 1:
JP 2000-226087 A - With the configuration as shown in
FIG. 14A , however, there is a possibility that the brittle thin-sheet materials 10 collide with thepackaging box 13 directly or via theportion bag 11, for example, due to vibration or dropping during transportation, and thus are broken. - In view of these circumstances, the present invention aims to provide a package capable of preventing breakage of brittle thin-sheet materials and also to provide a package assembly containing the package and a packaging method for forming the package.
- In order to solve the above problem, the package of the present invention includes: stacks each including a plurality of brittle thin-sheet materials; stack holders holding the stacks; and a packaging container including at least a body portion having a plurality of recessed portions, the package being characterized in that the stacks, together with the stack holders, are fitted in the recessed portions in such a manner that a face of each stack faces a bottom face of the recessed portion, the face of the stack being formed along a stacking direction of the stack.
- The package assembly of the present invention containing the above package is characterized by including the package and a packaging box containing the package.
- The packaging method of the present invention is characterized by including the steps of: holding stacks each including a plurality of brittle thin-sheet materials by stack holders; and fitting the stacks together with the stack holders into a plurality of recessed portions provided in a body portion of a packaging container in such a manner that a face of each stack faces a bottom face of the recessed portion, the face of the stack being formed along a stacking direction of the stack.
- According to the present invention, in the body portion of the packaging container, the stack including the brittle thin-sheet materials is fitted in the recessed portion of the body portion together with the stack holder in such a manner that a face of the stack that is formed along the stacking direction of the stack faces a bottom face of the recessed portion. Thus, the possibility of the brittle thin-sheet materials being broken by vibration or dropping during transportation can be reduced.

The following description relates to illustrative examples of the present invention, and the present invention is not limited by these examples.
- A
package 1 according to an embodiment of the present invention is shown inFIG. 1 . In the present embodiment, thepackage 1 is in the shape of a rectangular parallelepiped. Thepackage 1 is to be contained in apackaging box 7. A package assembly according to an embodiment of the present invention includes thepackage 1 and thepackaging box 7 containing thepackage 1. - The
packaging box 7 is, for example, a corrugated fiberboard box. For example, it is preferable that reinforcing plates be disposed on the inner faces (the four side faces, bottom face, and ceiling face) of thepackaging box 7 and thus be disposed between thepackaging box 7 and thepackage 1. Wooden boards (wood plates), compressed boards made of paper, foamed plastic boards, or the like, can be used as the reinforcing plates. With the use of thepackaging box 7 having reinforcing plates disposed between thepackaging box 7 and thepackage 1, thepackage 1 can be protected from external forces. Alternatively, a reinforcing plate may be joined between thepackage 1 and a part or the whole of at least one inner face of thepackaging box 7. In addition, a buffer member such as an elastic body or a bubble buffer material may be provided between thepackage 1 and a part or the whole of at least one inner face of thepackaging box 7. In this case, the reinforcing plate may be omitted. Also with such a configuration, thepackage 1 can be protected from external forces. - When the
packaging box 7 is a corrugated fiberboard box, thepackaging box 7 is constituted by outer linerboards, inner linerboards, and corrugating media having a wavy shape. The corrugating medium is disposed between and joined to the outer linerboard and the inner linerboard. The height of the flute (the distance between the outer linerboard and the inner linerboard) of thepackaging box 7 is, for example, 0.5 mm to 5mm, and preferably 1.5 to 5 mm. The mass per 1 m2 of each of the outer linerboard and the inner linerboard is, for example, 100 to 300 g, and preferably 150 to 280 g. The mass per 1 m2 of the corrugating medium is, for example, 100 to 200 g, and preferably 120 to 180 g. From the standpoint of enhancing the buffering properties, compressive strength, and breaking strength, a corrugated fiberboard box constituted by W-flute corrugated fiberboards each formed by stacking two types of corrugated fiberboards having flutes of different heights may be used. In this case, it is preferable to use a W-flute corrugated fiberboard formed by combination of a corrugated fiberboard having a 3-mm high flute and a corrugated fiberboard having a 5-mm high flute. - As shown in
FIG. 2A and FIG. 2B , thepackage 1 includes a plurality of (in the figures, ten)stacks 5 placed in an upright position and apackaging container 2 enclosing thestacks 5. In the present embodiment, thestacks 5 are arranged in two rows each consisting of five of thestacks 5. However, it is not necessary that thestacks 5 be arranged in two rows. For example, thestacks 5 may be arranged in a single row or may be arranged in three or more rows. Alternatively, thepackaging container 2 may be configured to enclose only asingle stack 5. - As shown in
FIG. 4 , eachstack 5 includes a plurality of brittle thin-sheet materials 50. Thestack 5 is held by astack holder 6 that is, for example, in the form of a bag. Thestack holder 6 may be any member that can prevent the plurality of brittle thin-sheet materials 50 from separating from each other and can maintain the stacking state of thestack 5. For example, thestack holder 6 may have the form of a rectangular envelope having two faces joined together at their respective three sides or the form of a rectangular file having two faces joined together at their respective two adjacent or opposite sides. The thickness of each face is, for example, 0.03 to 1.5 mm, preferably 0.04 mm to 1.0 mm, and more preferably 0.04 to 0.5 mm. For example, in the case where thestack holder 6 is in the form of an envelope, thestack 5 is inserted into thestack holder 6, after which the opening side of thestack holder 6 is folded and fixed by a tape and the four corners of thestack holder 6 are folded into a triangular shape and fixed by tapes in such a manner that theentire stack holder 6 is in close contact with thestack 5. Thus, thestack 5 is held, and the stacking state of the brittle thin-sheet materials 50 is maintained. Alternatively, thestack holder 6 can be in the form of a packaging film for holding thestack 5. In this case, reduced-pressure packaging or vacuum packaging can be achieved by depressurizing the inside of the packaging film serving as thestack holder 6. Furthermore, in this case, overwrap packaging, shrink packaging, packaging by an OPP (biaxially-oriented polypropylene) bag, or the like, may be employed. - The
stack 5 may be configured by stacking the brittle thin-sheet materials 50 alone, but is not limited to such a configuration. For example, as shown inFIG. 5 ,spacers 51 such as pieces of paper, sheet-like sponges, or polyethylene sheets may be disposed between the brittle thin-sheet materials 50. In this case, the respective one sides of the plurality ofspacers 51 may be joined together to form a book-shaped holder. In addition, a buffer member may be attached to at least a part of an outer surface of thestack 5. - The
stack holder 6 is not limited to that which is in the form of a bag. For example, as shown inFIG. 6 , the stack holder may be asingle sheet 63 for wrapping thestack 5. Alternatively, as shown inFIG. 7 , the stack holder may bebands 61 each surrounding two pairs of opposite side faces of thestack 5. Furthermore, as shown inFIG. 8 , the stack holder may be constituted by: twosheets stack 5 that are opposite to each other in a stacking direction of thestack 5; and aconnection portion 65B connecting thesheets sheet materials 50 may be joined to theconnection portion 65B. From the standpoint of enhancing protection of thestack 5, however, it is preferable that thestack holder 6 be configured to cover the whole of thestack 5. In particular, it is preferable that thestack holder 6 be in the form of a bag that can cover the whole of thestack 5. - The material of the
stack holder 6 that is in the form of a bag is not particularly limited. From the standpoint of preventing adhesion of dust, it is preferable to use a bag having antistatic properties. However, thestack holder 6 may be made of polyethylene or polypropylene. As used herein, the term "antistatic properties" means the property of having a surface resistivity of 1010 Ω/sq. or less or preferably 109 Ω/sq. or less under conditions of 20°C and 15%RH. - The number of the brittle thin-
sheet materials 50 constituting onestack 5 is, for example, about 5 to 500, and preferably about 10 to 200. In thestack holder 6, the brittle thin-sheet materials 50 may be stacked directly on each other, or each of the brittle thin-sheet materials 5 or sets of several brittle thin-sheet materials may be contained individually in a separate bag. In the case where the brittle thin-sheet material 5 is a structure in which one face and its reverse face are formed with different materials as described later, the brittle thin-sheet materials 5 may be stacked in alternately-inverted orientations so that the faces made of the same material face each other, or the brittle thin-sheet materials 5 may be stacked in the same orientation so that the faces made of different materials face each other. - The brittle thin-
sheet material 50 is a thin, brittle sheet material that could be fractured, chipped, or deformed during packaging, during transportation, or the like. A typical example thereof is a ceramic compact in the form of a thin-sheet. Examples of the ceramic compact in the form of a thin sheet include: a dense ceramic body for use in an electric circuit board or in an electrolyte sheet or separator of a solid oxide fuel cell (SOFC); a porous ceramic body for use in an electrode of a SOFC; a structure formed by combination of a plurality of dense ceramic bodies; a structure formed by combination of a dense ceramic body and a porous ceramic body; a structure (e.g., a single cell of a fuel cell) in which porous ceramic bodies are disposed on both sides of a dense ceramic body; and a structure formed by combination of a plurality of porous ceramic bodies. - The following can be used as the material of the dense ceramic body for use in an electric circuit board: alumina; zirconia; aluminum nitride; mullite; cordierite; a mixture of alumina and borosilicate glass; and a mixture of cordierite and borosilicate glass.
- The following can be used as the material of the dense ceramic body for use in an electrolyte sheet for an electrolyte-supported cell of a SOFC: stabilized zirconia having added thereto an oxide of a rare-earth element, an alkaline-earth element, or the like; a lanthanum gallate-based perovskite-type composite oxide such as LaGaO3 or LaSrGaMgO3; and a ceria-based composite oxide such as gadolinium-doped ceria or samaria-doped ceria.

sheet material 50 is not particularly limited, and may be any of a circular shape, an ellipsoidal shape, a rectangular shape, and a rounded-corner rectangular shape. Alternatively, the brittle thin-sheet material 50 may be in a shape having a hole for gas passage and, for example, may be in a doughnut shape. Also, grooves for scribing, or depressions presenting a dimple pattern, may be formed in the surface of the brittle thin-sheet material 50. - The outline area of the brittle thin-sheet material 50 (the area defined by the contour regardless of the presence or absence of a hole) is, for example, 25 cm2 or more and 1000 cm2 or less. The outline area of the brittle thin-
sheet material 50 is preferably 50 cm2 or more and 900 cm2 or less, and more preferably 80 cm2 or more and 600 cm2 or less. - The thickness of the brittle thin-
sheet material 50 is, for example, 0.03 mm or more and 0.5 mm or less. The thickness of the brittle thin-sheet material 50 is preferably 0.1 mm or more and 0.3 mm or less, and more preferably 0.12 mm or more and 0.25 mm or less. - When the brittle thin-

packaging container 2 is not particularly limited. It is recommended that at least a part of thepackaging container 2 be a foam. For example, polystyrene, which is inexpensive, can be used as the constituent material of the foam. From the standpoint of the strength of thepackaging container 2, however, reinforced polypropylene may be used. Alternatively, polyurethane may be used as the constituent material of the foam. For example, it is recommended that in thepackaging container 2, recessedportions 41 of abody portion 4 and alid portion 3 that are to come into contact with thestacks 5 or thestack holders 6 be formed of a foam. Alternatively, thepackaging container 2 may be constituted by corrugated fiberboards, compression boards made of paper, or the like. Furthermore, projections and depressions may be provided in the outer surface of thepackaging container 2. - When at least a part of the
packaging container 2 is a foam, the foaming magnification of the foam is preferably 10-fold or more and 90-fold or less, more preferably 20-fold or more and 80-fold or less, and even more preferably 30-fold or more and 70-fold or less, from the standpoint of the property of cushioning for the brittle thin-sheet materials. The entire foam need not have the same uniform foaming magnification. For example, in the recessedportions 41 of thebody portion 4 and thelid portion 3 which are in contact with thestacks 5 or thestack holders 6, the foaming magnification of the foam may be 40-fold to 90-fold and preferably 50 to 80-fold, while in other portions, the foaming magnification of the foam may be 10-fold to 60-fold and preferably 20 to 50-fold. The term "foaming magnification" as used herein means the volume per unit mass which is an inverse of the bulk density, and the unit of foaming magnification is "volume/mass". In the present description, "fold" is used instead of the unit "volume/mass". - The
body portion 4 has a plurality of (inFIG. 3B , ten) recessedportions 41. Eachstack 5, together with thestack holder 6, is fitted into the recessedportion 41. Eachstack 5, together with thestack holder 6, is fitted in the recessedportion 41, for example, in such a manner that a face of thestack 5 that is formed along the stacking direction faces the bottom face of the recessedportion 41. In the present embodiment, the depth of the recessedportion 41 is smaller than the length of one side of the brittle thin-sheet material 50, and the upper part of thestack 5 placed in an upright position projects from thebody portion 4. - The recessed
portion 41 has approximately the same shape as the lower part of thestack 5 placed in an upright position. That is, one of the horizontal dimensions of the recessedportion 41 is slightly larger than the length of another side of the brittle thin-sheet material, and the other horizontal dimension of the recessedportion 41 is slightly larger than the thickness of thestack 5. Therefore, when thestack 5, together with the packingmaterial 6, is fitted in the recessedportion 41, thestack 5 is held with its position maintained. It is preferable that a pair of faces of thestack 5 that are opposed to each other across the center of thestack 5 be fixed by the recessedportion 41. In this case, it is preferable that a pair of faces of thestack 5 that are opposed to each other across the center of thestack 5 and that are formed along the stacking direction of thestack 5 be fixed by the recessedportion 41. With these features, the possibility of the brittle thin-sheet materials being broken by vibration during transportation of thepackage 1 can be reduced. The center of thestack 5 is a midpoint of a line segment connecting the center of the principal face of the brittle thin-sheet material 50 disposed on one end of thestack 5 and the center of the principal face of the brittle thin-sheet material 50 disposed on the other end of thestack 5. - A distance D1 (see
FIG. 3B ) between each two recessedportions 41 adjacent in the stacking direction of thestack 5 may be determined as appropriate depending on the size of thestack 5, and may be 20 mm or less. From the standpoint of reducing the size of thepackaging container 2, the distance D1 is preferably 10 mm or less, more preferably 8 mm or less, and even more preferably 6 mm or less. From the standpoint of protecting thestacks 5, the distance D between the recessedportions 41 is, for example, 1 mm or more, and preferably 2 mm or more. - The
package 1 further includes thelid portion 3 covering thestacks 5 over the recessedportions 41. Thelid portion 3 covers thestacks 5 over thebody portion 4. In the present embodiment, thelid portion 3 is also provided with recessedportions 31 in each of which thestack 5, together with thestack holder 6, is fitted. It is preferable that a pair of faces of thestack 5 that are opposed to each other across the center of thestack 5 and that are formed along the stacking direction of thestack 5 be fixed by the recessedportion 41 and thelid portion 3. In other words, it is preferable that edge faces of thestack 5 that are opposed to each other across the center of thestack 5 be fixed by the recessedportion 41 and thelid portion 3. With this feature, it is possible to prevent thestack 5 from moving and colliding with thepackaging container 2 during transportation or the like. Accordingly, the possibility of the brittle thin-sheet material 50 being broken can be reduced. As shown inFIG. 9 , thelid portion 3 may be provided with ahollow portion 35 that is relatively large and surrounds the upper parts of all thestacks 5. In this case, thestacks 5 are pressed against the recessedportions 41 by the bottom face of thehollow portion 35. Alternatively, in the case where the depth of the recessedportion 41 of thebody portion 4 is slightly larger than one side of the brittle thin-sheet material 50, thelid portion 3 may be in the form of a flat plate. In this case, the space between thestacks 5 and thelid portion 3 is filled with a spacer or the like including a buffer member, so that thestacks 5 are pressed against the recessedportions 41 by thelid portion 3. Thestack holder 6 may serve as the spacer. Alternatively, the top face of thepackaging box 7 may be configured to serve as thelid portion 3. Still alternatively, thepackage 1 may include a plurality of lid portions each covering one or more of the recessedportions 41. - As shown in
FIG. 10 , the recessedportions 41 may be formed in an inclined manner. With this configuration, the height of thepackaging container 2 can be reduced. - As shown in
FIG. 11 , the depth of the recessedportion 41 provided in thebody portion 4 may be larger than one side of the brittle thin-sheet material 50. In this case, thelid portion 3 may further haveprojections 37 that fit in the recessedportions 41. With this feature, thestacks 50 can be pressed against the recessedportions 41 by theprojections 37 of thelid portion 3. In addition, thestacks 50 can be held further away from the outer face of thepackaging container 2 and, therefore, impact from outside can be reduced. - The magnitude relation between the height of the
body portion 4 and the height of thelid portion 3 is not particularly limited. The height of thebody portion 4 may be larger than the height of thelid portion 3 or the height of thelid portion 3 may be larger than the height of thebody portion 4. The height of thebody portion 4 and the height of thelid portion 3 may be equal. However, in order to protect thestacks 5 by deeper recessed portions, it is preferable that either the height of thebody portion 4 or the height of thelid portion 3 be larger than the other. - As shown in
FIG. 3A , a surroundingwall 32 in the form of a rectangular frame is formed along the periphery of the lower face of thelid portion 3. In addition, a steppedportion 42 into which the surroundingwall 32 fits is formed, as shown inFIG. 3B , along the periphery of the upper face of thebody portion 4. A recessed portion may be formed in the surroundingwall 32, and a projection that engages with the recessed portion may be formed in the steppedportion 42. Alternatively, a recessed portion may be formed in the steppedportion 42, and a projection that engages with the recessed portion may be formed in the surroundingwall 32. With the projection engaging with the recessed portion, thelid portion 3 is less likely to be detached from thebody portion 4. - As shown in
FIG. 12 ,projections 31A and 41A may be respectively formed on the side faces of the recessedportion 31 of thelid portion 3 and the side faces of the recessedportion 41 of thebody portion 4. A pair of the edge faces of thestack 5 that are opposed to each other across the center of thestack 5 may be fixed by theprojections 31A and 41A. The shape of the projection is not particularly limited, and may be a dimple-like shape that allows point contact with thestack 5 or thestack holder 6. Alternatively, the shape of the projection may be a shape that allows line contact with thestack 5 or thestack holder 6. Still alternatively, the shape of the projection may be a shape in which faces to be in contact with thestack 5 or thestack holder 6 are arranged at intervals. - Next, a method for forming the
package 1 will be described. - First, as shown in
FIG. 4 , thestacks 5 each including a plurality of brittle thin-sheet materials 50 are held by thestack holders 6. For example, thestacks 5 are put into thestack holders 6 that are in the form of a bag. At this time, it is preferable to seal thestacks 5 with thestack holders 6 as described above. Subsequently, thestacks 5, together with thestack holders 6, are fitted into the plurality of recessedportions 41 of thebody portion 4 of thepackaging container 2 in such a manner that a face of eachstack 5 that is formed along the stacking direction faces the bottom face of the recessedportion 41. Thelid portion 3 may be mounted so as to cover thestacks 5 over the recessedportions 41. Thus, thestacks 5 are covered by thelid portion 3. In the present embodiment, this operation may be performed along with insertion of thestacks 5 into the recessedportions 31 of thelid portion 3. In this manner, thepackage 1 is formed. - The
package 1 formed may be placed directly on a carrying pallet, but is preferably contained in thepackaging box 7 shown inFIG. 1 that has reinforcing plates joined to its inner faces. This is because deformation of thepackaging box 7 and thepackage 1 can be prevented even when a fork of a forklift accidentally contacts thepackaging box 7. - The
packaging container 2 according to another embodiment of the present invention is shown inFIG. 13 . Thelid portion 3 is in the form of a box having one open face. Thebody portion 4 includes abase portion 45 and a plurality ofpartition portions 47 arranged in an array on thebase portion 45. Recessedportions 49 are each formed by thebase portion 45 and the respective side faces of twoadjacent partition portions 47. Thestacks 5, together with thestack holders 6, are fitted into the recessedportions 49. In thebody portion 4, a steppedportion 45A is formed along the periphery of thebase portion 45 so as to surround thebase portion 45. Thelid portion 3 covers thestacks 5 over thebody portion 4 by being mounted on thebody portion 4 in such a manner that anedge portion 39 of the opening of thelid portion 3 and the steppedportion 45A are fitted together. In this case, the bottom face of thelid portion 3 presses thestacks 50 against thebase portion 45 constituting a part of each recessedportion 49. Thus, thestacks 5 can be held in thepackaging container 2. - In
FIG. 13 , the plurality ofpartition portions 47 are arranged in two rows so as to form two rows of the recessedportions 49. Thepartition portions 47 may be arranged in a single row or may be arranged in three or more rows. It is sufficient that the plurality ofpartition portions 47 be provided so as to form one or more recessedportions 49. The range of a distance D2 between the recessed portions 49 (the thickness of the partition portion 47) is the same as the range of the distance D1 between the recessedportions 41. - In the
package 1 of the present embodiment described above, the brittlethin film sheets 50 can be doubly protected by thepackaging container 2 and thestack holders 6 and, therefore, the breakage of the brittle thin-sheet materials 50 can be prevented. - In particular, when the brittle thin-
sheet material 50 is a zirconia-based material, it is possible to obtain a marked effect of preventing "chipping", "cracking", and "denting" of edge faces or principal faces of the brittle thin-sheet materials 50 where breakage would be particularly likely to occur. - Next, the present invention will be described with reference to examples. However, the examples given below are illustrative examples of the present invention, and the present invention is not limited to the examples given below.
- First, methods of evaluation of Examples and Comparative Example will be described. In accordance with JIS (Japanese Industrial Standards) Z 0202-1994, each of the packages and the package assemblies according to Examples and Comparative Example was allowed to free-fall from a height of 60 cm to a floor in such a manner that the drop attitude met the requirements for face drops. The floor was in a form having a concrete surface subjected to urethane coating. After the test, all of the sheets of 8YSZ (zirconia stabilized with 8 mol% of yttria) contained in the package or the package assembly was visually inspected for the breakage (fracture) of the sheets. In addition, detection of surface "chipping" and "cracking" was carried out by a transmissive photoelectric sensor for all the 8YSZ sheets. The number of 8YSZ sheets for which breakage or defect was observed was divided by the total number of the tested 8YSZ sheets to calculate the breakage rate and the defect generation rate.
- In accordance with JIS Z 0205-1998, incline impact tests were performed in which each of the packages and the package assemblies according to Examples and Comparative Example was placed on a sliding carriage on rails, and was allowed to collide with an impact plate at an inclination angle of 10°. After the test, all of the 8YSZ sheets contained in the package or the package assembly were visually inspected for breakage (fracture) of the sheets. In addition, detection of surface "chipping" and "cracking" was carried out by a transmissive photoelectric sensor for all the 8YSZ sheets. The number of 8YSZ sheets for which breakage or defect was observed was divided by the total number of the tested 8YSZ sheets to calculate the breakage rate and the defect generation rate.
- A stack formed by stacking 125 pieces of 120-mm square, 120-µm thick 8YSZ sheets (manufactured by NIPPON SHOKUBAI CO., LTD.) was put into a commercially-available antistatic polyethylene bag (thickness: 0.05 mm, surface resistivity: 108 Ω/sq.) serving as a stack holder. The opening of the bag was closed, and the edge on the opening side was folded and adhered to the outer surface of the bag. In addition, the four corners of the bag were folded in a triangular shape and adhered to the outer surface of the bag. In this manner, the stack was held by the stack holder. Next, ten such stacks each held by the stack holder were placed in a packaging container as shown in
FIG. 1 that was made of a polystyrene foam having a foaming magnification of about 50-fold. Specifically, each stack, together with the stack holder, was fitted into a recessed portion of the body portion of the packaging container in such a manner that the stacking direction of the stack coincided with the horizontal direction (a face of the stack that was formed along the stacking direction faced the bottom face of the recessed portion of the body portion of the packaging container). Then, a lid portion was mounted over the stacks. A pair of end portions (upper end portion and lower end portion) of each stack were fixed by the recessed portion and the lid portion. In this manner, a package according to Example 1 was fabricated. - Next, the above package was put in a packaging box as shown in
FIG. 1 , and foamed styrol plates having a foaming magnification of about 30-fold were inserted over the entire space between the package and the packaging box. The packaging box was a corrugated fiberboard box constituted by W-flute corrugated fiberboards each composed of two corrugated fiberboards one of which had an about 5-mm high flute and the other of which had an about 3-mm high flute. The weight of the linerboards of the corrugated fiberboards per 1 m2 was about 180 g. In the manner thus described, a package assembly according to Example 1 was fabricated. Free-fall drop tests and incline impact tests were carried out as described above for the package and the package assembly according to Example 1. The results of the free-fall drop tests are shown in Table 1, and the results of the incline impact tests are shown in Table 2. - Ten stacks fabricated in the same manner as in Example 1 and each held by the stack holder were inserted into recessed portions of the body portion of a polystyrene foam packaging container as shown in
FIG. 1 , and a lid portion was mounted over the stacks. A pair of end portions of each stack were fixed by the recessed portion and the lid portion. As a main material of the packaging container, a foam having a foaming magnification of about 40-fold was used. The packaging container had a structure in which sheets of a foam having a foaming magnification of 60-fold were provided on faces to be in contact with the stack holders by being joined to the main material by an adhesive agent. In the manner thus described, a package according to Example 2 was fabricated. - The above package was put in a packaging box as shown in
FIG. 1 , and veneer boards serving as reinforcing plates were inserted over the entire space between the package and the packaging box. The packaging box was a corrugated fiberboard box in which the height of the flute was about 3 mm and the weight of the linerboard per 1 m2 was about 220 g. In the manner thus described, a package assembly according to Example 2 was fabricated. Next, as in Example 1, free-fall drop tests and incline impact tests were performed, and all of the 8YSZ sheets contained in the package or the package assembly were inspected. The results of the free-fall drop tests are shown in Table 1, and the results of the incline impact tests are shown in Table 2. - Sets of the above 8YSZ sheets each consisting of ten pieces of the sheets were separately held by a book-shaped holder as shown
FIG. 8 that was made of paper and had a 120-mm square flat shape. Thus, a stack of 250 pieces of the 8YSZ sheets was fabricated. End portion buffer members were disposed on the upper face and the lower face of the stack, and a tape made of polypropylene (trade name: P.P. band, manufactured by SEKISUI CHEMICAL CO., LTD. and having a width of 15 mm) was wound around the stack in a cross shape to firmly bind the stack. Thus, a packed body was obtained. At this time, the surface pressure applied to the 8YSZ sheets was 200 gf/cm2. The end portion buffer members were polyethylene foams (trade name SUNPELCA L1400 manufactured by Hayashi Felt Co., Ltd.) having a size of 151 mm square, a thickness of 10 mm, and a density of 0.086 g/cm3. The end portion buffer members had, at their centers, a recessed portion (the shape of the recessed portion: 122-mm square, the depth of the recessed portion: 5 mm) into which each of the end portions of the stack was fitted. Next, four such packed bodies were each put in a commercially-available antistatic bag. Furthermore, each packed body contained in the bag was put in a tray-like buffering holder in such a manner that the stacking direction of the stack coincided with the vertical direction (in such a manner that a face of the stack formed along the stacking direction faced a side face of the recessed portion). Finally, the buffering holders holding the packed bodies were placed in a transport container that was a carrying case made of duralumin. The space between the transport container and the packed bodies contained in the antistatic bags was filled with cushioning materials made of polyethylene (trade name: ASPAC SARASARA, manufactured by Asahi Kasei Corporation). In this manner, a package assembly according to Comparative Example 2 was fabricated. Next, as in Example 1, a free-fall drop test and an incline impact test were performed for the package assembly, and all of the 1000 pieces of the 8YSZ sheets contained in the package assembly were inspected. The result of the free-fall drop test is shown in Table 1, and the result of the incline impact test is shown in Table 2.[Table 1] Packaging form Breakage rate (%) Defect generation rate (%) Chipping Cracking Example 1 Package 0.1 0.5 0 Package assembly 0 0.5 0.1 Example 2 Package 0 0.2 0 Package assembly 0 0.4 0 Comparative Example 1 Carrying case 3.4 1.1 4.7 [Table 2] Packaging form Breakage rate (%) Defect generation rate (%) Chipping Cracking Example 1 Package 0 0.4 0 Package assembly 0 0.5 0.1 Example 2 Package 0 0.1 0.1 Package assembly 0 0.2 0 Comparative Example 1 Carrying case 1.8 2.3 1.1 - From the results of the tests, the effectiveness of using the packages and the package assemblies according to Example 1 and Example 2 was confirmed. The breakage rates in Example 1 and Example 2 were smaller than the breakage rate in Comparative Example 1. In addition, the defect generation rates for chipping and cracking in Example 1 and Example 2 were smaller than the defect generation rates for chipping and cracking in Comparative Example 1.
