Summary of the Invention

Problems to be Solved by the Invention

[0005] For example, a plurality of buffer members independent of each other are stored in a case together with a package as a cushioning material. Each of the plurality of buffer members contacts the package and protects the package. Each of the plurality of buffer members protects different portions of the package. By arranging a plurality of buffer members in the storage case, even if the storage case falls or the like, the impact on the package can be buffered.

[0006] Here, when the storage case falls or the like, any one of the buffer members may be deformed. The buffer member buffers the impact on the package by being deformed. However, when any one of the buffer members is deformed, play occurs in the deformed buffer member. And the arrangement position of the deformed buffer member may deviate from the initial position.

[0007] If any of the cushioning materials become misaligned, the misaligned cushioning material will no longer be able to protect the area it is supposed to protect. If the storage case is subjected to impact in this state, the contents will not be adequately protected, which could result in damage to the contents.

[0008] The present invention was made to solve the above problems and aims to provide a packaging member that can suppress displacement of the cushioning member. [Means for solving the problem]

[0009] To achieve the above objective, a packaging member according to one aspect of the present invention comprises a storage case for storing a package, and a plurality of cushioning members arranged inside the storage case so as to surround the package, wherein each of the plurality of cushioning members has an engaging portion, and each of the plurality of cushioning members is connected to other cushioning members via the engaging portion. [Effects of the Invention]

[0010] The configuration of the present invention can suppress displacement of the cushioning member. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0012] The packaging member 100 of this embodiment will be described below with reference to Figures 1 to 21. In the following description, the X direction in the figures is defined as the left-right direction (corresponding to the "horizontal direction"), the Y direction is defined as the front-back direction, and the Z direction is defined as the up-down direction.

[0013] As shown in Figure 1, the packaging component 100 includes a storage case 200. The storage case 200 contains the packaged item 300. The packaged item 300 is, for example, a printer.

[0014] Furthermore, as shown in Figures 1 to 3, the packaging member 100 comprises a plurality of independent cushioning members 10. That is, each of the multiple cushioning members 10 is a separate component from the other cushioning members 10. Each of the multiple cushioning members 10 is made of paper. The multiple cushioning members 10 are arranged inside the storage case 200. The multiple cushioning members 10 protect the packaged goods 300 inside the storage case 200.

[0015] The storage case 200 is made of, for example, a corrugated cardboard sheet. The storage case 200 has an opening 200A on its upper side in the vertical direction. Multiple cushioning members 10 are inserted into and removed from the storage case 200 through the opening 200A. That is, the direction in which the cushioning members 10 are inserted into and removed from the storage case 200 is vertical. The packaged goods 300 are similarly inserted into and removed from the storage case 200 through the opening 200A.

[0016] Although not shown in the diagram, after the package 300 is placed inside, the opening 200A is closed by a flap integrally formed with the body of the storage case 200. After the package 300 is placed inside, the opening 200A may also be closed by a lid member separate from the body of the storage case 200. When placing or removing the package 300, the opening 200A is opened.

[0017] Furthermore, the number of cushioning members 10 is 7. The number of cushioning members 10 constituting the packaging member 100 is not particularly limited; it may be less than 7 or 8 or more. In the following description, multiple cushioning members 10 may be distinguished by assigning reference numerals 1 to 7 to each.

[0018] Multiple cushioning members 10 are arranged inside the storage case 200 so as to surround the packaged item 300. The multiple cushioning members 10 are positioned between the inner surface of the storage case 200 and the packaged item 300, and are in contact with the packaged item 300. The multiple cushioning members 10 support the packaged item 300 so that it does not move inside the storage case 200.

[0019] Two of the multiple cushioning members 10 are positioned on the lower side in the vertical direction inside the storage case 200. Hereinafter, the two cushioning members 10 positioned on the lower side inside the storage case 200 will be denoted as reference numerals 1 and 2, respectively, to distinguish them from the other cushioning members 10. A separate view of cushioning member 1 is shown in Figure 4, and a separate view of cushioning member 2 is shown in Figure 5.

[0020] One of the lower cushioning members 1 is positioned on the left side in the left-right direction, contacts the lower left corner of the package 300, and supports the lower left corner of the package 300. The other lower cushioning member 2 is positioned on the right side in the left-right direction, contacts the lower right corner of the package 300, and supports the lower right corner of the package 300.

[0021] Cushioning members 1 and 2 are hollow pulp molded products formed from pulp molded material using a mold by the pulp molding method. When the storage case 200 is dropped or otherwise, the pulp molded products deform to cushion (absorb) the impact on the packaged goods 300. Cushioning members 3 and 4, described later, are also pulp molded products.

[0022] Two of the multiple cushioning members 10 are positioned on the upper side in the vertical direction inside the storage case 200. Hereinafter, the two cushioning members 10 positioned on the upper side inside the storage case 200 will be denoted as reference numerals 3 and 4, respectively, to distinguish them from the other cushioning members 10. A separate view of cushioning member 3 is shown in Figure 6, and a separate view of cushioning member 4 is shown in Figure 7.

[0023] One of the upper cushioning members 3 is positioned on the left side in the left-right direction, contacts the upper left corner of the packaged item 300, and supports the upper left corner of the packaged item 300. The other upper cushioning member 4 is positioned on the right side in the left-right direction, contacts the upper right corner of the packaged item 300, and supports the upper right corner of the packaged item 300.

[0024] In the following description, three of the multiple cushioning members 10, separate from cushioning members 1 to 4, will be denoted by reference numerals 5 to 7. Individual views of cushioning member 5 are shown in Figures 8 and 9, individual views of cushioning member 6 are shown in Figure 10, and individual views of cushioning member 7 are shown in Figure 11.

[0025] The cushioning members 5 to 7 are, for example, members formed by folding a corrugated cardboard sheet. The cushioning members 5 to 7 have hollow portions (cylindrical portions) formed by folding a corrugated cardboard sheet.

[0026] The cushioning member 5 has a function to assist in loading and unloading the packaged goods 300 (hereinafter simply referred to as the auxiliary function). Details will be described later. Note that the cushioning member 5 does not necessarily have to have the auxiliary function.

[0027] The cushioning member 5 has a left side portion 510, a right side portion 520, and a lower side portion 530.

[0028] The left side 510 faces the left side of the package 300 in the left-right direction, and the right side 520 faces the right side of the package 300 in the left-right direction. In other words, the left side 510 and the right side 520 face each other in the left-right direction with the package 300 in between. The left side 510 has a side plate 501 that faces the left side of the package 300, and the right side 520 has a side plate 502 that faces the right side of the package 300. The pair of side plates 501 and 502 are parallel (including substantially parallel) to the YZ plane. The pair of side plates 501 and 502 face each other in the left-right direction with the package 300 in between.

[0029] The packaged item 300 is sandwiched between a pair of side plates 501 and 502 in the left-right direction. The pair of side plates 501 and 502 may be in contact with the packaged item 300. Alternatively, cushioning material (for example, a pulp molded product) may be separately provided on each of the pair of side plates 501 and 502. The cushioning material may then be in contact with the packaged item 300 (the cushioning material may also support the packaged item 300).

[0030] The left side 510 has a rectangular hollow section 511 on its front side in the front-to-back direction, and the right side 520 has a rectangular hollow section 521 on its front side in the front-to-back direction. The hollow section 511 is fixed to the front part of the side plate 501, and the hollow section 521 is fixed to the front part of the side plate 502. Inside the storage case 200, the hollow section 511 is located in the front left corner, and the hollow section 521 is located in the front right corner. The hollow section 511 supports the left side of the front of the packaged item 300, and the hollow section 521 supports the right side of the front of the packaged item 300.

[0031] The lower portion 530 is a hollow, rectangular tube. The lower portion 530 includes a front lower portion 531 and a rear lower portion 532. The front lower portion 531 is located on the front side in the front-rear direction inside the storage case 200, contacts the front portion of the packaged item 300, and supports the front portion of the packaged item 300. The rear lower portion 532 is located on the rear side in the front-rear direction inside the storage case 200, contacts the rear portion of the packaged item 300, and supports the rear portion of the packaged item 300.

[0032] The left side 510 and the right side 520 are connected to each other. In other words, the pair of side plates 501 and 502 are connected to each other. Specifically, the cushioning member 5 has a bottom plate 50 that faces the bottom surface of the packaged goods 300. The bottom plate 50 connects the pair of side plates 501 and 502 to each other below. The lower ends of the pair of side plates 501 and 502 are each connected to the bottom plate 50. Hereinafter, the connection points between the lower ends of the pair of side plates 501 and 502 and the bottom plate 50 will be denoted by the symbol CP.

[0033] For example, in the production of the cushioning member 5, a corrugated cardboard sheet is prepared that integrally has a left side portion 510, a right side portion 520, and a lower side portion 530. The left side portion 510 (side plate 501) is then folded perpendicularly to the portion that will become the bottom plate 50. The right side portion 520 (side plate 502) is also folded perpendicularly to the portion that will become the bottom plate 50 so that it faces the left side portion 510 (side plate 501). Figure 9 schematically shows a state in which the left side portion 510 is completely folded and the right side portion 520 is partially folded.

[0034] The cushioning member 6 is positioned on the front side in the front-to-back direction inside the storage case 200. The cushioning member 6 contacts the front portion of the packaged item 300. The cushioning member 6 supports the front portion of the packaged item 300.

[0035] The cushioning member 6 has hollow portions 61 and 62 that extend vertically in a rectangular tubular shape. Inside the storage case 200, the hollow portion 61 is located on the left side, and the hollow portion 62 is located on the right side. The positions of the cylindrical axes of the hollow portion 511 of the cushioning member 5 and the hollow portion 61 of the cushioning member 6 are approximately coincident. The positions of the cylindrical axes of the hollow portion 521 of the cushioning member 5 and the hollow portion 62 of the cushioning member 6 are approximately coincident.

[0036] The cushioning member 7 is positioned at the rear in the front-to-back direction inside the storage case. The cushioning member 7 contacts the rear portion of the packaged item 300. The cushioning member 7 supports the rear portion of the packaged item 300.

[0037] Here, of the multiple cushioning members 10, cushioning members 1 and 2 are placed first inside the storage case 200. After cushioning members 1 and 2 are placed, cushioning member 5 is placed inside the storage case 200. After cushioning member 5 is placed, cushioning members 6 and 7 are placed inside the storage case 200. Cushioning members 3 and 4 are placed inside the storage case 200 last.

[0038] Next, the positioning of the cushioning member 10 will be described.

[0039] Each of the multiple cushioning members 10 has an engaging portion E. The engaging portion E of each of the multiple cushioning members 10 engages with the engaging portion E of the adjacent cushioning member 10. In other words, each of the multiple cushioning members 10 is connected to the adjacent cushioning member 10 via the engaging portion E. This positions the multiple cushioning members 10 relative to the packaged item 300.

[0040] Each of the engaging parts E, one on each side, is an engaging projection and an engaging hole, respectively. That is, each engaging part E is composed of an engaging projection and an engaging hole. The engaging projection extends in the vertical direction. The engaging hole is a hole through which the engaging projection can be inserted and removed. A detailed explanation follows below.

[0041] The engaging portion E of cushioning member 1 and the engaging portion E of cushioning member 2 engage with the engaging portion E of cushioning member 5. The positioning structure of cushioning member 1 and cushioning member 5 is shown in Figure 12. In the following description, when it is necessary to distinguish the engaging portions E, the engaging portion E of cushioning member 1 that engages with cushioning member 5 is denoted by the numeral E1, and the engaging portion E of cushioning member 2 that engages with cushioning member 5 is denoted by the numeral E2. The engaging portion E of cushioning member 5 that engages with engaging portions E1 and E2 is denoted by the numeral E51.

[0042] The positioning of cushioning member 1 and cushioning member 5 is performed in the same manner as the positioning of cushioning member 2 and cushioning member 5. Therefore, the positioning structure diagram for cushioning member 2 and cushioning member 5 is omitted, as it is based on the positioning structure diagram for cushioning member 1 and cushioning member 5.

[0043] The engaging portions E1 and E2 are engaging projections. The engaging portions E1 and E2 are convex portions that protrude upward in the vertical direction. The cushioning member 1 has one engaging portion E1 on its front and one on its rear side. The cushioning member 2 has one engaging portion E2 on its front and one on its rear side.

[0044] The engaging portion E51 is an engaging hole. The engaging portion E51 is a hole into which the engaging projections, which are the engaging portions E1 and E2, can be inserted. The engaging portion E51 is not limited to a hole; it can be any part into which the engaging projections can be inserted. For example, the engaging portion E51 may be a concave portion.

[0045] The engaging portion E51 is formed in the plate-like portion that constitutes the lower surface (the surface facing downwards) of the lower portion 530. In other words, the engaging portion E51 is a hole that penetrates the plate-like portion that constitutes the lower surface of the lower portion 530 in the vertical direction. To put it another way, the engaging portion E51 is an opening formed in the lower surface (plate-like portion) of the lower portion 530.

[0046] One engaging portion E51 is formed on the left side of each of the front lower portion 531 and the rear lower portion 532. In other words, the engaging portion E51 is positioned in a location that overlaps vertically with the formation area of ​​the engaging portion E1.

[0047] As a result, after placing the cushioning member 1 at the bottom of the storage case 200, the cushioning member 5 is placed on top of the cushioning member 1 from above, thereby inserting the engaging portion E1 into the engaging portion E51. Consequently, the cushioning member 1 and the cushioning member 5 are connected.

[0048] Furthermore, one engaging portion E51 is formed on the right side of each of the front lower portion 531 and the rear lower portion 532. In other words, the engaging portion E51 is positioned in a location that overlaps vertically with the formation area of ​​the engaging portion E2.

[0049] As a result, the cushioning member 2 is first placed at the bottom of the storage case 200, and then the cushioning member 5 is placed on top of the cushioning member 2 from above, so that the engaging portion E2 is inserted into the engaging portion E51. Consequently, the cushioning member 2 and the cushioning member 5 are connected.

[0050] Furthermore, the cushioning member 5 is positioned adjacent to and above cushioning members 1 and 2. In other words, when considering cushioning members 1, 2, and 5, cushioning members 1 and 2 correspond to the "first cushioning member," and cushioning member 5 corresponds to the "second cushioning member."

[0051] By inserting the engaging portion E1 into the engaging portion E51, the cushioning members 1 and 5 are positioned relative to each other. Similarly, by inserting the engaging portion E2 into the engaging portion E51, the cushioning members 2 and 5 are positioned relative to each other. In other words, the cushioning members 1, 2, and 5 are held in place so as not to move in a direction parallel to the XY plane (horizontal direction perpendicular to the vertical direction).

[0052] The engaging portion E of the cushioning member 3 and the engaging portion E of the cushioning member 4 engage with the engaging portion E of the cushioning member 6. The positioning structure of the cushioning member 3 and the cushioning member 6 is shown in Figure 13, and the positioning structure of the cushioning member 4 and the cushioning member 6 is shown in Figure 14. In the following description, when it is necessary to distinguish the engaging portions E, the engaging portion E of the cushioning member 3 that engages with the cushioning member 6 is denoted by the reference numeral E31, and the engaging portion E of the cushioning member 4 that engages with the cushioning member 6 is denoted by the reference numeral E41. In addition, the engaging portion E of the cushioning member 6 that engages with the engaging portions E31 and E41 is denoted by the reference numeral E61.

[0053] The engaging portions E31 and E41 are engaging holes. The engaging portions E31 and E41 are holes that penetrate in the vertical direction. For example, holes are formed in the cushioning members 3 and 4 after the pulp molding process. The cushioning member 3 has one engaging portion E31 on its front side. The cushioning member 4 has one engaging portion E41 on its front side.

[0054] The engaging portion E61 is an engaging projection. The engaging portion E61 is a plate-shaped projection that protrudes upward. The engaging portion E61 can be inserted into the engaging holes that form the engaging portions E31 and E41. For example, the engaging portion E61 can be obtained by folding a part of the corrugated cardboard sheet that forms the cushioning member 6. The plate-shaped projection that serves as the engaging portion E61 may be added to the main body of the cushioning member 6 afterwards.

[0055] One engaging portion E61 is formed on the left and one on the right side of the buffer member 6. In other words, the left engaging portion E61 is positioned in a location that overlaps vertically with the formation area of ​​engaging portion E31, and the right engaging portion E61 is positioned in a location that overlaps vertically with the formation area of ​​engaging portion E41.

[0056] As a result, after placing the cushioning member 6 inside the storage case 200, the cushioning members 3 and 4 are placed on top of the cushioning member 6 from above, so that the engaging portion E61 is inserted into the engaging portions E31 and E41. Consequently, the cushioning member 6 and the cushioning members 3 and 4 are connected.

[0057] Furthermore, cushioning members 3 and 4 are positioned adjacent to and above cushioning member 6. In other words, when considering cushioning members 3, 4, and 6, cushioning member 6 corresponds to the "first cushioning member," and cushioning members 3 and 4 correspond to the "second cushioning members."

[0058] Furthermore, the engaging portion E of the cushioning member 3 and the engaging portion E of the cushioning member 4 engage with the engaging portion E of the cushioning member 7. The positioning structure of the cushioning member 3 and the cushioning member 7 is shown in Figure 15, and the positioning structure of the cushioning member 4 and the cushioning member 7 is shown in Figure 16. In the following description, when it is necessary to distinguish the engaging portions E, the engaging portion E of the cushioning member 3 that engages with the cushioning member 7 is denoted by the reference numeral E32, and the engaging portion E of the cushioning member 4 that engages with the cushioning member 7 is denoted by the reference numeral E42. In addition, the engaging portion E of the cushioning member 7 that engages with the engaging portions E32 and E42 is denoted by the reference numeral E71.

[0059] The engaging portion E32 is a notch formed at the left rear corner of the plate-like portion parallel to the XY plane (horizontal direction perpendicular to the vertical direction). The engaging portion E42 is a notch formed at the right rear corner of the plate-like portion parallel to the XY plane. The cushioning member 3 has one engaging portion E32 (plate-like portion with a notch) on its rear side. The cushioning member 4 has one engaging portion E42 (plate-like portion with a notch) on its rear side.

[0060] The engaging portion E71 is a notch formed at the upper front corner of a plate-like portion parallel to the YZ plane. The engaging portion E71 (plate-like portion with a notch) is obtained by folding a part of the corrugated cardboard sheet that will become the cushioning member 7. The plate-like portion with a notch, which serves as the engaging portion E71, may be added to the main body of the cushioning member 7 afterwards.

[0061] One engaging portion E71 is formed on the left and one on the right side of the buffer member 7. In other words, the left engaging portion E71 is positioned in a location that overlaps vertically with the formation area of ​​the engaging portion E32, and the right engaging portion E71 is positioned in a location that overlaps vertically with the formation area of ​​the engaging portion E42.

[0062] As a result, after placing the cushioning member 7 inside the storage case 200, the cushioning members 3 and 4 are placed on top of the cushioning member 7 from above, causing the engaging portions E32 and E42 to engage with the engaging portion E71, and connecting the cushioning member 7 with the cushioning members 3 and 4.

[0063] The configurations of the engaging portions E32, E421, and E71 are not particularly limited. The engaging portions E32 and E42 may be engaging projections, and the engaging portion E71 may be an engaging hole. Alternatively, the engaging portions E32 and E42 may be engaging holes, and the engaging portion E71 may be an engaging projection.

[0064] The cushioning members 3, 4, 6, and 7 are positioned relative to each other by the engagement of engagement portion E31 and E41 with engagement portion E61, and by the engagement of engagement portions E32 and E42 with engagement portion E71. As a result, the cushioning members 3, 4, 6, and 7 are held in place so as not to move in a direction parallel to the XY plane (horizontal direction perpendicular to the vertical direction).

[0065] Furthermore, the cushioning member 5 and the cushioning member 6 are connected (engaged). The positioning structure of the cushioning member 5 and the cushioning member 6 is shown in Figures 17 and 18. In the following description, when it is necessary to distinguish the engaging portion E, the engaging portion E of the cushioning member 5 that engages with the cushioning member 6 is denoted by the reference numeral E52. The engaging portion E of the cushioning member 6 that engages with the engaging portion E52 is denoted by the reference numeral E62.

[0066] The engaging portion E52 is an engaging hole. The engaging portion E62 is an engaging projection. There are two engaging portions E52, which are the upper portions (upper ends) in the vertical direction of the hollow portions 511 and 521, respectively. In other words, the engaging portion E52 is the hole (opening) at the upper end of the hollow portions 511 and 521, respectively. There are two engaging portions E62, which are the lower portions in the vertical direction of the hollow portions 61 and 62, respectively (see Figure 10).

[0067] As a result, after placing the cushioning member 5 inside the storage case 200, the cushioning member 6 is placed on top of the cushioning member 5 from above, so that the lower portions of the hollow portions 61 and 62 of the cushioning member 6 (i.e., the engaging protrusions) are inserted into the hollow portions 511 and 521 of the cushioning member 5 (i.e., the engaging holes). Consequently, the cushioning member 5 and the cushioning member 6 are connected.

[0068] Furthermore, the cushioning member 6 is positioned adjacent to and above the cushioning member 5. In other words, when considering cushioning members 5 and 6, cushioning member 5 corresponds to the "first cushioning member," and cushioning member 6 corresponds to the "second cushioning member."

[0069] Furthermore, the cushioning member 5 and the cushioning member 7 are connected (engaged). The positioning structure of the cushioning member 5 and the cushioning member 7 is shown in Figures 19 and 20. In the following description, when it is necessary to distinguish the engaging portion E, the engaging portion E of the cushioning member 5 that engages with the cushioning member 7 is denoted by the reference numeral E53. The engaging portion E of the cushioning member 7 that engages with the engaging portion E53 is denoted by the reference numeral E72.

[0070] There are two engaging parts E53. One of the engaging parts E53 is on the left side. Side panel This is a slit cut into 501 from above. The other engaging part E53 is on the right side Side panel This is a slit cut into 502 from above. Side panel 501 and 502 have an engaging portion E53 on the rear side.

[0071] The engaging portion E72 is, in a plan view from the top and bottom Side panelThis is a slit cut from below into a plate-like portion parallel to the XZ plane that intersects (including perpendicular to) 501 and 502. One engaging portion E72 is formed on the left and one on the right. In other words, the engaging portion E72 on the left side is Side panel The engaging portion E53 of 501 is positioned where it overlaps (intersects) in the vertical direction, and the engaging portion E72 on the right side is, Side panel It is positioned where the engaging portion E53 of 502 overlaps (intersects) in the vertical direction.

[0072] As a result, after placing the cushioning member 5 inside the storage case 200, the cushioning member 7 is placed on top of the cushioning member 5 from above, causing the engaging portion E53 and the engaging portion E72 to engage and connect the cushioning member 5 and the cushioning member 7.

[0073] The configurations of the engaging portions E53 and E72 are not particularly limited. The engaging portion E53 may be an engaging projection and the engaging portion E72 may be an engaging hole. Alternatively, the engaging portion E53 may be an engaging hole and the engaging portion E72 may be an engaging projection.

[0074] The engagement of engagement portion E52 and engagement portion E62, and the engagement of engagement portion E53 and engagement portion E72, position the cushioning members 5 to 7 relative to each other. This holds the cushioning members 5 to 7 in a direction parallel to the XY plane (horizontal direction perpendicular to the vertical direction).

[0075] In this embodiment, as described above, each of the multiple cushioning members 10 (1 to 7) has an engaging portion E. Each of the multiple cushioning members 10 is connected to other adjacent cushioning members 10 via the engaging portion E. In this configuration, even if one of the cushioning members 10 deforms and looseness occurs between the deformed cushioning member 10 and the packaged goods 300, the deformed cushioning member 10 is connected to the other cushioning members 10, so it is possible to suppress the position of the deformed cushioning member 10 from shifting from its initial position.

[0076] By suppressing the displacement of the deformed cushioning member 10, the inconvenience of the deformed cushioning member 10 failing to adequately protect the parts of the packaged goods 300 that it should protect can be prevented. Therefore, when the storage case 200 is subjected to impact again, damage to the packaged goods 300 can be prevented.

[0077] Furthermore, in this embodiment, as described above, by placing the cushioning member 10 to be placed inside the storage case 200 next (corresponding to the "second cushioning member") on top of the cushioning member 10 to be placed inside the storage case 200 next (corresponding to the "first cushioning member") from above, the engaging projection is inserted into the engaging hole, and the first cushioning member and the second cushioning member are connected. With this configuration, by simply placing multiple cushioning members 10 in order inside the storage case 200 through the opening 200A, the cushioning member 10 that has been placed first and the cushioning member 10 that will be placed next can be connected. As a result, there is no need to perform a separate operation to connect the cushioning members 10 to each other, thus improving work efficiency.

[0078] Next, we will describe the cushioning member 5 which has an auxiliary function.

[0079] In a configuration where the cushioning member 5 has an auxiliary function, the cushioning member 5 corresponds to the "third cushioning member". The cushioning member 5 is positioned vertically between cushioning members 1 and 2 and cushioning members 6 and 7. The cushioning member 5 is connected to cushioning members 1 and 2 below and to cushioning members 6 and 7 above via the engaging portion E. Cushioning members 6 and 7 are connected to cushioning members 3 and 4.

[0080] As a result, in a configuration where the cushioning member 5 has an auxiliary function, cushioning members 1 and 2 become members corresponding to the "first cushioning member." Also, cushioning members 6 and 7 become members corresponding to the "second cushioning member." Furthermore, cushioning members 3 and 4 are indirectly connected to cushioning member 5 via cushioning members 6 and 7. For this reason, cushioning members 3 and 4 also become members corresponding to the "second cushioning member."

[0081] As shown in Figure 9, the pair of side plates 501 and 502 of the cushioning member 5 are movable, respectively, in a direction toward and away from the side surface of the packaged item 300, with the connection point CP as the pivot point. In other words, the pair of side plates 501 and 502 move, respectively, with the connection point CP as the pivot point, by swinging the end opposite to the connection point CP.

[0082] In some cases, after placing cushioning members 1 and 2 inside the storage case 200, cushioning member 5 is attached to the packaged item 300, and then the cushioning member 5 is placed inside the storage case 200 together with the packaged item 300. At this time, if the left side 510 and the right side 520 move away from the packaged item 300, the packaging work becomes difficult.

[0083] Therefore, in this embodiment, as described above, the left side portion 510 has engaging portions E52 and E53 at the end opposite to the connecting portion CP. The engaging portion E52 is engaged with the engaging portion E62 of the buffer member 6, and the engaging portion E53 is engaged with the engaging portion E72 of the buffer member 7.

[0084] In this configuration, with the pair of side plates 501 and 502 sandwiching the packaged item 300 in the left-right direction (i.e., the horizontal direction perpendicular to the up-down direction), the engaging portions E52 and E53 of the cushioning member 5 engage with the engaging portion E62 of the cushioning member 6 and the engaging portion E72 of the cushioning member 7, respectively, thereby holding the pair of side plates 501 and 502 in a position facing each other in the left-right direction while sandwiching the packaged item 300. In other words, when the cushioning member 5 is placed in the storage case 200 together with the packaged item 300, engaging the cushioning members 6 and 7 with the cushioning member 5 prevents the pair of side plates 501 and 502 from moving away from the sides of the packaged item 300. As a result, the workability of the package is improved.

[0085] Furthermore, in this configuration, when unpacking the packaging material 100 and removing the packaged item 300 from the top of the storage case 200, after removing the cushioning materials 3 and 4, the pair of side plates 501 and 502 can be grasped and the packaged item 300 can be lifted up. This improves the work efficiency when removing the packaged item 300.

[0086] Furthermore, a handle portion 500 is formed at the top of each of the pair of side plates 501 and 502. Each handle portion 500 of the pair of side plates 501 and 502 is an opening that penetrates in the direction of the plate thickness.

[0087] At this point, after the package 300 is lifted, the engagement between the cushioning member 5 (i.e., the third cushioning member) and the cushioning members 6 and 7 (i.e., the second cushioning members) is released. As a result of the release of the engagement between the cushioning member 5 and the cushioning members 6 and 7, as shown in Figure 21, the pair of side plates 501 and 502 open in a direction away from the side of the package 300, with the connection point CP with the bottom plate 50 (see Figure 9) as the pivot point. Then, the handle portion 500 becomes grippable. As a result, the package 300 becomes easier to carry.

[0088] Furthermore, in the process of opening the package 300, the package 300 can be opened by simply removing the cushioning members 6 and 7 from the cushioning member 5. In other words, it is not necessary to perform any additional work such as cutting the cushioning member 5. As a result, the convenience for the worker is improved.

[0089] The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is indicated by the claims rather than by the description of the embodiments above, and furthermore, all modifications within the meaning and scope equivalent to the claims are included.
