Description

Packaging material, packaging body, module assembly and packaging method of module

Technical Field

The invention relates to a packaging material, a packaging body, a module assembly and a packaging method of a module.

Background

Conventionally, when a blood purification method such as hemodialysis and plasmapheresis is performed, a membrane module having a treatment membrane such as a hollow fiber membrane built therein and an adsorption module having an adsorbent such as beads built therein (hereinafter, these may be collectively referred to as a "module") have been used. Conventionally, various packaging materials have been proposed for preventing modules from directly contacting each other or preventing the ends of the modules from directly contacting the inner wall of a box in the interior of the box, thereby suppressing breakage of the modules due to vibration and impact during transportation (for example, refer to patent documents 1 and 2).

Problems to be solved by the invention

Further, the module is usually used for transportation in a state of being packed by the packing bag, but when the conventional packing material as described in patent document 1 and patent document 2 is used, the module is strongly contacted with the packing material or wrinkles are easily generated in the packing bag, and thus there is a problem that the packing bag is easily broken. In addition, when the module includes a top cover portion having a complicated shape (for example, having a plurality of irregularities on a side surface thereof), strength against impacts and the like during conveyance tends to be lowered, and therefore, development of an improved packaging material is desired.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a packaging material capable of suppressing breakage of a top cover portion of a module and breakage of a packaging bag for packaging the module.

Solution for solving the problem

In order to achieve the above object, the present invention provides a packaging material for packaging a module having a tubular main body and top cover sections attached to both ends of the main body in a longitudinal direction, the packaging material comprising: a main body support surface that at least partially supports a lower surface of a main body of the module in a recumbent state; a main body portion supporting wall that supports both side surfaces of a main body portion of a module in a recumbent state so as to sandwich the side surfaces; and a top surface supporting wall for supporting the top surfaces of the top cover parts on both sides of the module in a recumbent state, wherein the packaging material is not contacted with the side surfaces of the top cover parts when the module is supported by the main body supporting surface, the main body supporting wall and the top surface supporting wall.

In this configuration, the lower surface of the body of the module in the horizontal state can be supported at least partially by the body support surface, and the two side surfaces of the body of the module can be supported by the body support wall so as to sandwich the two side surfaces, so that the movement of the module in the left-right direction (direction perpendicular to the longitudinal direction of the module) can be suppressed. Further, the top surfaces of the top cover portions on both sides of the module in the recumbent state can be supported by the top surface support wall, so that the movement of the module in the longitudinal direction can be suppressed. In addition, since the packaging material does not contact the side surface of the top cover portion of the module when the module is supported by the main body portion support surface, the main body portion support wall, and the top surface support wall, the side surface of the top cover portion of the module can be prevented from being broken or the packaging bag covering the side surface of the top cover portion can be prevented from being broken.

The packaging material of the present invention may include leg portions that protrude downward from the main body support surface. In this case, the leg portion can be disposed below the main body portion of the module.

In this case, the leg portion is provided so as to protrude downward from the main body support surface and is disposed below the main body of the module, so that the packaging material can be disposed in a stable state while suppressing deformation (strain) of the packaging material when the packaging material is disposed in the interior of the case or on the shelf.

In the packaging material of the present invention, the leg portion can be disposed at a substantially central portion in the width direction of the module supported by the main body portion support surface.

In this configuration, the leg portions are disposed at the substantially central portion in the width direction of the module supported by the main body portion support surface, so that the weight of the module can be supported immediately below the module (at the substantially central portion in the width direction). Thus, deformation (strain) of the packaging material can be suppressed.

In the packaging material of the present invention, a plurality of leg portions may be provided along the longitudinal direction of the module supported by the main body support surface. In this case, the plurality of legs can be arranged substantially symmetrically about a substantially central portion in the longitudinal direction of the module.

In this case, the plurality of leg portions are provided along the longitudinal direction of the module supported by the main body support surface, and the plurality of leg portions are arranged substantially symmetrically about the substantially central portion of the module in the longitudinal direction, so that the weight of the module can be dispersed and the module can be supported by the entire packaging material. Thus, the force is not biased toward a part of the packaging material, and deformation (strain) of the packaging material can be suppressed.

In the packaging material of the present invention, the plurality of main body support surfaces can be provided separately so as to support a plurality of portions along the longitudinal direction of the lower surface of the main body of the module. In this case, the main body support wall and the leg portion can be disposed between adjacent main body support surfaces and connected by a continuous surface.

In this configuration, the plurality of main body support surfaces are provided separately, so that the lower surface of the main body of the module can be supported at a plurality of positions along the longitudinal direction. Further, since the body support wall and the leg portion disposed between the adjacent body support surfaces are connected by the continuous surface, the rigidity and strength of the package can be improved.

In the packaging material of the present invention, the body portion support surface, the body portion support wall, the top surface support wall, and the leg portion can be integrally formed.

When this structure is adopted, the respective structures (the main body portion support surface, the main body portion support wall, the top surface support wall, and the leg portions) of the packaging material are integrally formed, and therefore, the packaging material can be easily manufactured as compared with a case where separate members are connected. In addition, since the respective structures of the packaging material are integrated, the packaging material is easy to carry, and packaging work and disassembly work are easy to perform.

In the packaging material of the present invention, when the second packaging material is stacked on the module supported by the first packaging material, the leg portions of the second packaging material can be arranged so that the leg portions at least partially support the upper surface of the main body portion of the module.

When this structure is adopted, the lower surface of the main body of the module can be supported by the main body support surface of the first packaging material, while the upper surface of the main body of the module can be supported by the leg portions of the second packaging material, so that the module can be sandwiched from above and below. Thus, the movement of the module in the up-down direction can be suppressed.

In the packaging material of the present invention, when the second packaging material is stacked on the module supported by the first packaging material and the leg portions of the second packaging material at least partially support the upper surface of the main body portion of the module, the second packaging material may not contact the side surfaces of the top cover portion of the module.

When this structure is adopted, since the second packaging material is stacked on the module supported by the first packaging material and the leg portions of the second packaging material at least partially support the upper surface of the main body portion of the module, the second packaging material does not contact the side surface of the top cover portion of the module, and therefore it is possible to prevent the packaging bag covering the side surface of the top cover portion of the module from being pinched between the side surface and the second packaging material and becoming wrinkled or broken. In addition, the following can be prevented: when a large impact is applied in the vertical direction when the module is mounted on the second packaging material, the side surface of the top cover portion of the module disposed on the first packaging material and the side surface of the top cover portion of the module disposed on the second packaging material are contacted with each other via the second packaging material and are subjected to the impact, and the side surfaces are broken.

In the packaging material of the present invention, when the module has the protruding pin protruding from the side surface of the top cover portion, a region for receiving the protruding pin can be formed between the first packaging material and the second packaging material.

When this structure is adopted, the following can be prevented: the protruding pin is pressed by the packaging material and is impacted, so that the protruding pin is broken or the packaging bag around the protruding pin is broken.

In the packaging material of the present invention, at least a part of the main body support surface may be a flat surface, and the main body support wall may be disposed substantially perpendicularly to the flat surface.

In this configuration, since the main body support wall is disposed substantially perpendicularly to the flat surface constituting at least a part of the main body support surface, the module can be supported as if the main body of the module is housed in a box having a bottom surface (flat surface of the main body support surface) and two side surfaces (main body support walls) connected substantially perpendicularly to the bottom surface.

In the packaging material of the present invention, in the case where the top surface of the top cover portion of the module has a flat surface portion substantially orthogonal to the longitudinal direction of the module and a shaft portion protruding from the flat surface portion along the longitudinal direction of the module, the top surface support wall can support at least a portion of the top surface below the shaft portion.

When this structure is adopted, at least a portion (one portion) of the flat surface portion of the top surface of the top cover portion of the module, which is located below the shaft portion, can be supported by the top surface support wall. Therefore, the flat surface portion of the top surface can be supported in a larger range than in the case where the portion (two portions) on the side of the shaft portion is supported in the flat surface portion of the top surface as in the conventional art. In addition, in the case of covering the top cover portion of the module with the packaging bag, the top surface of the top cover portion can be supported in a relatively flat state (a state in which wrinkles are less likely to occur), and therefore breakage of the packaging bag can be prevented.

The packaging material of the present invention may include a module support portion having a main body portion support surface, a main body portion support wall, and a top surface support wall, the module support portion supporting a single module. In this case, the plurality of module support portions may be provided so as to support the plurality of modules in a state of being arranged parallel to each other. In this case, when the modules are supported by the module support portions, the side surfaces of the top cover portions of the adjacent modules may not contact each other.

In the case of using this configuration, when the modules are supported by the plurality of module supports, the side surfaces of the top cover portions of the adjacent modules do not contact each other, and therefore, it is possible to prevent the package bag covering the side surfaces of the top cover portions of the modules from being damaged by the contact between the side surfaces of the top cover portions. In addition, the following can be prevented: when a large impact is applied in the lateral direction when the module is mounted on the packaging material, the side surface of the top cover portion of the module contacts with the side surface of the top cover portion of the module disposed adjacent thereto and is subjected to the impact, which causes breakage of the side surfaces.

In the packaging material of the present invention, when the modules are supported by the respective module support portions, the side surfaces of the top cover portions of the adjacent modules may be provided without a partition wall therebetween.

In the case of using this structure, when the modules are supported by the plurality of module supports, the side surfaces of the top cover portions of the adjacent modules are not separated from each other by the partition wall, and therefore, the package bag covering the side surfaces of the top cover portions of the modules can be prevented from being damaged by the partition wall. In addition, the size of the packaging material in the transverse direction can be reduced by the absence of the partition wall, and the module can be compactly stored.

The package of the present invention is provided with the above-described packaging material and a case for housing the packaging material. The package may include a spacer member that seals a gap formed between an upper surface of the main body of the module supported by the packaging material and an inner surface of the case facing the upper surface of the main body.

With this structure, the gap formed between the upper surface of the main body portion of the module supported by the packaging material and the inner surface of the box opposing the upper surface can be blocked by the spacer member, so that the module can be restrained from moving in the up-down direction. In addition, when stacking a plurality of layers of modules supported by a packaging material, it is also possible to suppress movement in the up-down direction of the whole of them.

The present invention also provides a module assembly including a module having a tubular main body and a top cover attached to both longitudinal ends of the main body, and the packaging material described above.

In addition, the present invention provides a method for packaging a module, in which a module having a tubular main body and top cover portions attached to both longitudinal ends of the main body is packaged in a box using the packaging material described above, wherein the lower surface of the main body of the module in a lying state is at least partially supported by the main body support surface of the packaging material, both side surfaces of the main body of the module in a lying state are supported by the main body support wall of the packaging material so as to sandwich both side surfaces of the main body of the module, the top surfaces of the top cover portions on both sides of the module in a lying state are supported by the top surface support wall of the packaging material, and the packaging material is not in contact with the side surfaces of the top cover portions of the module when the module is supported by the main body support surface, the main body support wall, and the top surface support wall of the packaging material.

Detailed Description

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

First, the structure of a packaging material 1 according to an embodiment of the present invention will be described with reference to fig. 1 to 8. The packaging material 1 of the present embodiment is used for packaging a membrane module (module) M used for performing a blood purification method such as hemodialysis therapy or plasmapheresis therapy, a virus removal of a biological medicine or a blood preparation, a water purification treatment, or the like, in a case B (see fig. 9), for example. The packaging material of the present invention can be used not only for the packaging film module M but also for an adsorption module having an adsorbent such as beads incorporated therein.

As shown in fig. 2, the module M wrapped with the wrapping material 1 of the present embodiment includes a tubular main body M1, cap portions M2 attached to both ends of the main body M1 in the longitudinal direction L, and protruding pins M3 protruding from side surfaces M21 of the cap portions M2. The top surface M22 of the top cover portion M2 of the module M has a flat surface portion M221 that is substantially orthogonal to the longitudinal direction L of the module M, and a shaft portion M222 that protrudes from the flat surface portion M221 along the longitudinal direction L of the module M. A module assembly is formed by the packaging material 1 and the module M.

As shown in fig. 4 to 8, the packaging material 1 is configured to be stackable in the up-down direction H. In the following description, when two packaging materials 1 stacked in the up-down direction H are distinguished from each other, the packaging material 1 disposed below is referred to as "first packaging material 1A", and "a" is added to the end of the reference numeral of each structure of the first packaging material 1A, while the packaging material 1 disposed above is referred to as "second packaging material 1B", and "B" is added to the end of the reference numeral of each structure of the second packaging material 1B.

As shown in fig. 1 and the like, the packaging material 1 includes a plurality of module support portions 2 for supporting individual modules M, and the plurality of module support portions 2 are arranged along a lateral direction (a direction orthogonal to a longitudinal direction L of the modules M) W so as to support the plurality of modules M in a state of being arranged parallel to each other. In the present embodiment, as shown in fig. 2, an example is shown in which the packaging material 1 having 4 module supporting portions 2 is used, but the number of module supporting portions 2 is not limited to this.

When the modules M are supported by the respective module support portions 2, as shown in fig. 2 and 5, there is no partition wall between the side surfaces M21 of the top cover portions M2 of the adjacent modules M, and the side surfaces M21 of the top cover portions M2 of the adjacent modules M are not in contact with each other.

Each module support portion 2 of the packaging material 1 has a main body portion support surface 10, a main body portion support wall 20, a top surface support wall 30, and leg portions 40.

The main body support surface 10 functions to at least partially support the lower surface M11 of the main body M1 of the module M in the recumbent state. As shown in fig. 6 and the like, the main body support surface 10 is provided in plurality so as to support a plurality of portions along the longitudinal direction L of the lower surface M11 of the main body M1 of the module M, and 1 of the main body support surfaces 10 (surfaces that support substantially the central portion in the longitudinal direction L of the lower surface M11 of the main body M1 of the module M) is a flat surface 11. When the module M is incorporated into the packaging bag, the module M is in contact with the flat surface 11 at 1 point, and therefore, a space is created around the module M, and wrinkles are not likely to occur in the packaging bag. In the present embodiment, as shown in fig. 6 and the like, 3 main body support surfaces 10 are provided, and 1 of the main body support surfaces 10 (a surface located at a substantially central portion in the longitudinal direction L) is set as the flat surface 11, but the number of the main body support surfaces 10 and the flat surfaces 11, and the positions of the flat surfaces 11 are not limited thereto. The ratio of the total length of the body portion support surfaces 10 in the longitudinal direction L to the distance between the top surface support walls 30 in the longitudinal direction L of the packaging material 1 is preferably 30% or more.

The main body portion support wall 20 functions as follows: the two side surfaces M12 of the main body M1 of the module M in the horizontal state are supported so as to sandwich the two side surfaces M12. As shown in fig. 1 and the like, the main body support wall 20 is arranged substantially perpendicular to the flat surface 11 of the main body support surface 10. In the present embodiment, as shown in fig. 1 and the like, the main body portion support wall 20 is provided in two separate portions along the longitudinal direction L so as to support two portions along the longitudinal direction L of the both side surfaces M12 of the main body portion M1. As described above, in the present embodiment, since the main body portion support wall 20 is not provided at the substantially central portion in the longitudinal direction L, the module M is easily placed on the packaging material 1 during the packaging operation.

In the present embodiment, the two main body support walls 20 along the longitudinal direction L are arranged substantially symmetrically about the substantially central portion in the longitudinal direction L, and the recesses 21 for improving the strength are provided in each of the two main body support walls 20 along the longitudinal direction L. The number and shape of the main body support walls 20 are not limited to this, but in order to suppress movement of the module M in the width direction W, the height of the main body support walls 20 (the dimension indicated by the reference symbol T in fig. 4, that is, the dimension from the lowermost portion of the main body support surface 10 to the uppermost portion of the main body support walls 20 in the up-down direction H) is preferably set to 50% or more of the diameter of the main body M1 of the module M. The height of the main body support 20 can be set to 50% or more of the distance between the adjacent main body support walls 20, regardless of the diameter of the main body M1 of the module M. The height of the main body portion support wall 20 is more preferably set to 55% or more, and even more preferably set to 60% or more of the diameter of the main body portion M1 of the module M (and/or the distance between adjacent main body portion support walls 20). In addition, when considering the ease of taking out the module M and the ease of manufacturing the packaging material 1, the height of the main body portion support wall 20 is preferably set to 150% or less, more preferably 100% or less, and even more preferably 75% or less of the diameter of the main body portion M1 of the module M (and/or the distance between adjacent main body portion support walls 20). The total length of the main body support walls 20 along the longitudinal direction L is not particularly limited, but may be appropriately set in consideration of ease of placement of the module M during packaging operation, formation of an air discharge passage in the packaging bag when the module M is incorporated into the packaging bag, strength of the main body support walls 20, and the like.

The top support wall 30 functions to support the top surfaces M22 of the top cover portions M2 on both sides of the module M in the horizontal state. As shown in fig. 6 and the like, the top surface support wall 30 in the present embodiment is configured to support a relatively large portion (one portion) of the flat surface portion M221 of the top surface M22 of the top cover portion M2 of the module M, which is located below the shaft portion M222. Therefore, the flat surface portion M221 of the top surface M22 can be supported in a larger range than in the case where the relatively narrow portions (two portions) on the side of the shaft portion M222 in the flat surface portion M221 of the top surface M22 are supported. In addition, in the case of using the top cover M2 of the package cover module M, the top surface M22 of the top cover M2 can be supported in a relatively flat state (a state in which wrinkles are less likely to occur) of the package, and therefore breakage of the package can be prevented.

In the present embodiment, when the main body portion M1 of the module M is supported by the main body portion support surface 10, the main body portion support wall 20, and the top surface support wall 30, as shown in fig. 5 and 6, the packaging material 1 does not contact the side surface M21 of the top cover portion M2 of the module M (i.e., a gap is formed between the side surface M21 of the top cover portion M2 of the module M and the packaging material 1).

The leg portion 40 protrudes downward from the main body support surface 10, and functions to support the module M via the main body support surface 10 and the like. As shown in fig. 6 and the like, a plurality of (4) leg portions 40 are provided along the longitudinal direction of the module M supported by the main body support surface 10, and these 4 leg portions 40 are arranged substantially symmetrically about a substantially central portion in the longitudinal direction L of the module M. The leg 40 is disposed below the main body M1 of the module M supported by the main body support surface 10, and is disposed at a substantially central portion in the width direction (lateral direction W) of the module M.

In the present embodiment, as shown in fig. 4 and 6, when the second packaging material 1B is stacked on the module M supported by the first packaging material 1A, the leg portions 40B are arranged so that the leg portions 40B of the second packaging material 1B at least partially support the upper surface M13 of the main body portion M1 of the module M (the leg portions 40B at least partially come into contact with the upper surface M13 of the module M). In the present embodiment, since 4 legs 40 are provided, the upper surface M13 of the module M is supported at 4 places (the upper surface M13 of the module M is abutted at 4 places).

The number and shape of the leg portions 40 are not limited to this, and the length and the installation area along the longitudinal direction L of the installation surface of the leg portions 40 can be set within a range that can support the weight of the module M when an impact is applied. When two or more layers are stacked, it is preferable to set the length and area of the leg 40B so that the package bag can be placed between the leg 40B and the leg 40B of the upper package material 1B when the package bag is filled with the module M and air is present in the package bag, and the leg 40B of the upper layer can be provided in the body M1 without floating.

In the present embodiment, as shown in fig. 5 and 6, when the second packaging material 1B is stacked on the module M supported by the first packaging material 1A and the leg 40B of the second packaging material 1B at least partially supports the upper surface M13 of the main body M1 of the module M (when the leg 40B at least partially abuts the upper surface M13 of the module M), the second packaging material 1B is not in contact with the side surface M21 of the top cover M2 of the module M, and at this time, as shown in fig. 4 and 5, a region a for receiving the protruding plug M3 of the module M is formed between the first packaging material 1A and the second packaging material 1B. When the protruding pins M3 of the module M disposed at a position close to the outer peripheral edge of the packaging material 1 are horizontal, the outer peripheral edge of the packaging material 1 is preferably located outside the tip end portion of the protruding pins M3 of the module M. In this way, breakage or the like of the protruding pin M3 due to the protruding pin M3 of the module M protruding outward from the outer peripheral edge of the packaging material 1 can be prevented.

As shown in fig. 3, the packaging material 1 of the present embodiment is configured to be laterally symmetrical in the longitudinal direction L of the module M (i.e., configured to be line symmetrical across the center line in the longitudinal direction L) and also configured to be laterally symmetrical in the transverse direction W (i.e., configured to be line symmetrical across the center line in the width direction W) in a plan view. By forming the packaging material 1 in such a symmetrical shape, there is an advantage that the packaging work of the module M is easy to perform and the stacking work of the packaging materials 1 to each other is easy to perform.

As shown in fig. 1 to 3, a recess 50 is provided in the outer peripheral edge of the packaging material 1 of the present embodiment at a substantially central portion in the longitudinal direction L of the module M in a plan view. By providing such a recess 50 on the outer periphery of the packaging material 1, the operator can easily hold the packaging material 1 by hand, and can easily put in and take out the packaging material 1 from the box B. With this, there is an advantage that the packaging work of the module M and the removal work of the module M from the box B can be easily performed.

The main body support surface 10, the main body support wall 20, the top support wall 30, and the leg portions 40 of each module support portion 2 are integrally formed by a usual pulp molding method, injection molding method, or the like. As shown in fig. 3 and the like, the main body support wall 20 and the leg 40 of each module support 2 are disposed between adjacent main body support surfaces 10 (main body support surfaces 10 adjacent to each other in the longitudinal direction L of the module support 2) and are connected by continuous surfaces. By connecting the main body portion support wall 20 and the leg portion 40 of each module support portion 2 with continuous surfaces, the strength of the module support portion 2 and the packaging material 1 can be improved. In the present embodiment in which the plurality of module support portions 2 are provided so that the plurality of modules M are arranged parallel to each other, the main body support walls 20 and the leg portions 40 are alternately arranged in the lateral direction W across the adjacent module support portions 2, and the main body support walls 20 and the leg portions 40 are connected by continuous surfaces. This can improve the strength of the packaging material 1 having the plurality of module support portions 2. Each module support portion 2 (packaging material 1) may be made of paper such as newspaper waste paper and corrugated paper, synthetic resin such as polystyrene, polypropylene and polyethylene terephthalate, foamable synthetic resin such as polyurethane and polystyrene, or the like. In the present embodiment, the module support portions 2 (the main body support surface 10, the main body support wall 20, the top support wall 30, and the leg portions 40) are integrally molded, but a plurality of members may be combined to form the module support portions.

Next, the structure of the package 100 according to the embodiment of the present invention will be described with reference to fig. 9.

As shown in fig. 9, the package 100 of the present embodiment includes a packaging material 1 and a box B accommodating the packaging material 1. As already described above for the packaging material 1. As the case B, for example, a case having a substantially rectangular parallelepiped shape formed of corrugated paper or the like can be used. In the package 100, a gap G is formed between the upper surface M13 of the main body M1 of the uppermost module M supported by the packaging material 1 and the inner surface B1 of the box B facing the upper surface M13 of the main body M1, but a spacer member S that partially closes the gap G may be provided. By providing such a spacer member S, movement of the module M in the up-down direction can be suppressed, and movement of the entire stacked multi-layer module M in the up-down direction can be suppressed.

The shape of the spacer member S is not particularly limited as long as it can at least partially close the gap G formed between the upper surface M13 of the main body M1 of the uppermost module M and the inner surface B1 of the tank B. The material of the spacer member S is not particularly limited as long as it can suppress movement of the module M in the up-down direction. For example, a plurality of sheets of corrugated paper having a predetermined thickness can be overlapped as the spacing member S. In addition, a plate-like (thin rectangular parallelepiped) spacer member S having a predetermined thickness made of paper or foamable synthetic resin may be used. In addition to the spacer member S, a sheet member (pad) having a substantially rectangular shape in plan view, for example, made of corrugated paper or the like, may be provided between the uppermost module M and the inner surface (upper surface) B1 in the box B, and the sheet member (pad) and the spacer member S may be integrated.

In the packaging material 1 of the above-described embodiment, the lower surface M11 of the main body M1 of the module M in the recumbent state can be at least partially supported by the main body support surface 10, and the two side surfaces M12 of the main body M1 of the module M can be supported by the main body support wall 20 so as to sandwich the two side surfaces M12, so that the movement of the module M in the left-right direction (the width direction W perpendicular to the longitudinal direction L of the module M) can be suppressed. Further, the top surface support wall 30 can support the top surfaces M22 of the top cover portions M2 on both sides of the module M in the horizontal state, so that the movement of the module M in the longitudinal direction L can be suppressed. In addition, since the packaging material 1 is not in contact with the side surface M21 of the top cover M2 of the module M when the module M is supported by the main body support surface 10, the main body support wall 20, and the top support wall 30, breakage of the side surface M21 of the top cover M2 of the module M itself or breakage of the packaging bag covering the side surface M21 of the top cover M2 can be prevented.

Further, since the packaging material 1 of the above-described embodiment includes the leg portion 40 protruding downward from the main body portion support surface 10 and disposed below the main body portion M1 of the module M, when the packaging material 1 is disposed in the interior of the box B or on the shelf, the packaging material 1 can be disposed in a state in which the packaging material 1 is stabilized while suppressing deformation (strain) of the packaging material 1. The leg 40 can absorb the shock received from below, and can alleviate the shock acting on the module M.

In the packaging material 1 according to the above-described embodiment, the leg 40 is disposed at the substantially central portion in the width direction (the lateral direction W) of the module M supported by the main body support surface 10, so that the weight of the module M can be supported immediately below (the substantially central portion in the width direction) the module M. Thus, deformation (strain) of the packaging material 1 can be suppressed.

In the packaging material 1 according to the above-described embodiment, the plurality of leg portions 40 are provided along the longitudinal direction L of the module M supported by the main body support surface 10, and the plurality of leg portions 40 are arranged substantially symmetrically about the substantially central portion of the module M in the longitudinal direction L, so that the weight of the module M can be dispersed and the module M can be supported by the entire packaging material 1. Thus, the force is not biased toward a part of the packaging material 1, and deformation (strain) of the packaging material 1 can be suppressed.

In the packaging material 1 according to the above-described embodiment, the plurality of main body support surfaces 10 are provided separately, so that the lower surface M11 of the main body M1 of the module M can be supported at a plurality of positions along the longitudinal direction. Further, since the body support wall 20 and the leg portion 40 disposed between the adjacent body support surfaces 10 are connected by continuous surfaces, the rigidity and strength of the packaging material 1 can be improved.

In addition, in the packaging material 1 of the above-described embodiment, since the respective structures (the main body portion support surface 10, the main body portion support wall 20, the top surface support wall 30, and the leg portion 40) are integrally formed, it is easier to manufacture than when separate members are connected. Further, since the respective structures of the packaging material 1 are integrated, the packaging material is easy to carry, and packaging work and disassembly work are easy to perform.

In the packaging material 1 of the above-described embodiment, the lower surface M1 of the main body M1 of the module M can be supported by the main body support surface 10A of the first packaging material 1A, while the upper surface M13 of the main body M1 of the module M can be supported by the leg 40B of the second packaging material 1B, so that the module M can be sandwiched from above and below. Thus, the movement of the module M in the up-down direction can be suppressed.

In the packaging material 1 of the above-described embodiment, when the second packaging material 1B is stacked on the module M supported by the first packaging material 1A and the leg 40B of the second packaging material 1B at least partially supports the upper surface M13 of the main body M1 of the module M, the second packaging material 1B is not in contact with the side surface M21 of the top cover M2 of the module M, and therefore, the packaging bag covering the side surface M21 of the top cover M2 of the module M can be prevented from being pinched between the side surface M21 and the second packaging material 1B and being folded or broken. In addition, the following can be prevented: when a large impact is applied in the vertical direction when the module M is mounted on the second packaging material 1B, the side surface M21 of the top cover portion M2 of the module M disposed on the first packaging material 1A and the side surface M21 of the top cover portion M2 of the module M disposed on the second packaging material 1B are contacted with each other via the second packaging material 1B and are subjected to the impact, and thus they are broken.

In the packaging material 1 of the above-described embodiment, the region a of the protruding plug M3 of the storage module M protruding from the side surface M21 of the top cover M2 is formed between the first packaging material 1A and the second packaging material 1B, and therefore, the following can be prevented: the protruding pin M3 is pressed by the packaging material 1 and is impacted, so that the protruding pin M3 is broken or the packaging bag around the protruding pin M3 is broken.

In the packaging material 1 of the above-described embodiment, since the main body support wall 20 is disposed substantially perpendicularly to the flat surface 11 constituting at least a part of the main body support surface 10, the lower surface M11 and the side surfaces M12 of the main body M1 of the module M can be supported just as if the main body M1 of the module M is housed in a case having a bottom surface (the flat surface 11 of the main body support surface 10) and two side surfaces (the main body support wall 20) connected substantially perpendicularly to the bottom surface.

In the packaging material 1 of the above-described embodiment, at least a relatively large portion (one portion) of the flat surface portion M221 of the top surface M22 of the top cover portion M2 of the module M, which is located below the shaft portion M222, can be supported by the top surface support wall 30. Accordingly, the flat surface portion M221 of the top surface M22 can be supported over a wider range than in the case where the relatively narrow portions (two portions) on the side of the shaft portion M222 are supported in the flat surface portion M221 of the top surface M22 as in the conventional art. In addition, in the case of using the top cover M2 of the package cover module M, the top surface M22 of the top cover M2 can be supported in a relatively flat state (a state in which wrinkles are less likely to occur) of the package, and therefore breakage of the package can be prevented.

In the packaging material 1 of the above-described embodiment, when the modules M are supported by the plurality of module support portions 2, the side surfaces M21 of the top cover portions M2 of the adjacent modules M do not contact each other, and therefore, it is possible to prevent the package bag covering the side surfaces M21 of the top cover portions M2 of the modules M from being damaged by the contact between the side surfaces M21 of the top cover portions M2. In addition, the following can be prevented: when a large impact is applied in the left-right direction when the module M is mounted on the packaging material 1, the side surface M21 of the top cover M2 of the module M contacts and is impacted by the side surface M21 of the top cover M2 of the module M disposed adjacent thereto on the packaging material 1, and the side surfaces are broken.

In the packaging material 1 according to the above-described embodiment, when the modules M are supported by the plurality of module support portions 2, there is no partition wall between the side surfaces M21 of the top cover portions M2 of the adjacent modules M, and therefore, it is possible to prevent the package bag covering the side surfaces M21 of the top cover portions M21 of the modules M from being damaged by the partition wall. In addition, the dimension of the packaging material 1 in the lateral direction can be shortened by the absence of the partition wall, and the module M can be compactly housed.

In the package 100 according to the above-described embodiment, the gap G formed between the upper surface M13 of the main body M1 of the module M supported by the packaging material 1 and the inner surface B1 of the box B facing the upper surface M13 can be closed by the spacer member S, so that the module M can be prevented from moving in the vertical direction. In addition, when stacking a plurality of layers of modules M supported by the packaging material 1, it is also possible to suppress movement of the whole thereof in the up-down direction.
