[Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-43764 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure aims to suppress a decrease in the posture-maintaining function of the packaged object and a decrease in the shock-absorbing function of the cushioning material even if the cushioning side wall separates from the cushioning bottom of the cushioning material, compared to when there is only surface contact between the exterior side wall of the outer box and the cushioning side wall of the cushioning material. [Means for solving the problem]

[0005] The packaging body of a first embodiment comprises an outer box having an outer bottom and an outer side wall rising from an edge of the outer bottom, a cushioning material having a buffer bottom positioned on top of the outer bottom and supporting the underside of an object to be packaged, and a buffer side wall rising from an edge of the buffer bottom and supporting the side of the object to be packaged, and a holding portion that holds the relative position of the buffer side wall with respect to the outer side wall.

[0006] In the packaging body of the second aspect, in the first aspect, at least a part of the holding portion is disposed at a position equal to or higher than the boundary height between the upper surface of the buffer bottom and the inner surface of the buffer side wall.

[0007] In a packaging body of a third aspect, in the second aspect, a first portion of the exterior side wall including the holding portion protrudes upward from a second portion where the holding portion is not provided.

[0008] In a fourth aspect of the packaging body, in any of the first to third aspects, the retaining portion has an exterior side fitting portion provided on the exterior side wall and a buffer side fitting portion provided on the buffer side wall corresponding to the exterior side fitting portion.

[0009] In the packaging body of the fifth aspect, in the fourth aspect, the exterior side fitting portion is a hole portion formed in the exterior side wall, and the buffer side fitting portion is a protrusion portion formed in the buffer side wall corresponding to the hole portion.

[0010] In the packaging body of the sixth embodiment, in the fifth embodiment, the width measured along the vertical direction of the hole is greater than the width measured along the vertical direction of the protrusion, and before the buffer bottom supports the bottom surface of the packaged item, there is a gap between the lower edge of the hole and the lower edge of the protrusion.

[0011] In a packaging body of a seventh aspect, in addition to the fifth or sixth aspect, the exterior side wall has a solid portion above the hole as a suppression portion that suppresses the protrusion from coming off.

[0012] A method for transporting a packaged body of an eighth embodiment comprises: an outer box having an outer bottom and an outer side wall rising from an edge of the outer bottom; a cushioning material having a buffer bottom placed on the outer bottom and a buffer side wall rising from an edge of the buffer bottom; and a holding part for holding the relative position of the buffer side wall with respect to the outer side wall, and the packaged body has an object stored inside, and the packaged body is transported in a state in which the underside of the object is supported by the buffer bottom and the side surfaces of the object are supported by the buffer side walls. Effect of the Invention

[0013] According to the configuration of the first aspect, compared to a case where the exterior side wall of the exterior box and the buffer side wall of the buffer material are only in surface contact, even if the buffer side wall separates from the buffer bottom of the buffer material, it is possible to suppress the deterioration of the posture-maintaining function of the packaged object and the deterioration of the shock-absorbing function of the buffer material.

[0014] According to the configuration of the second aspect, even if separation occurs at the boundary, it is possible to suppress a decrease in the movement suppression function of the separated buffer side wall, compared to a case in which the retaining portion is provided at the height of the bottom portion.

[0015] According to the configuration of the third aspect, the amount of flesh of the exterior side wall used can be reduced compared to when the height of the second portion of the exterior side wall where no retaining portion is provided is aligned with the height of the first portion including the retaining portion.

[0016] According to the configuration of the fourth aspect, the holding portion can be configured more simply than when the holding portion is configured with an adhesive.

[0017] According to the configuration of the fifth aspect, it is possible to suppress the cost of parts and reduce the number of work steps, compared to a case in which the holding portion is configured using separate parts other than the exterior box and the cushioning material.

[0018] According to the configuration of the sixth aspect, damage to the protrusion or the exterior side wall can be suppressed, compared to a case in which the lower edge of the hole and the lower edge of the protrusion are in contact with each other.

[0019] According to the configuration of the seventh aspect, it is possible to prevent the protrusion from slipping out upward, compared to when the hole is a notch that opens to the upper part of the exterior side wall.

[0020] According to the configuration of the eighth aspect, even if the buffer side wall is separated from the buffer bottom of the buffer material, it is possible to suppress the deterioration of the posture-maintaining function of the packaged object and the deterioration of the shock-absorbing function of the buffer material, compared to a case where the exterior side wall of the outer box and the buffer side wall of the buffer material are simply in surface contact.

FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] Hereinafter, an example of an embodiment according to the present disclosure will be described with reference to the drawings. <<Embodiment>> <Packaging> First, an example of a packaging body 10 according to the present embodiment will be described with reference to Fig. 1 to Fig. 5. As shown in Fig. 1, the packaging body 10 according to the present embodiment is a packaging device or member that packages an object 20 to be packaged.

[0023] (Items to be packaged) The packaged object 20 in this embodiment is, for example, an image forming device, but may be changed as desired in the present disclosure. In the packaged object 20, among the members located on the outer surface of the image forming device when packaged, the strength of the part where a space is formed inside, the strength of the part where there is little support from other members, the strength of the part where the wall thickness is relatively thin, or the strength of the part where a combination of these is configured is relatively low. Therefore, it is easily broken by impact. As a result, the cushioning material 14 is arranged in contact with the packaged object 20 so that the contact area of ​​the cushioning material 14 with the easily breakable part of the packaged object 20 is large.

[0024] (Packaging) As shown in Fig. 1, the package 10 includes an outer box 12, a cushioning material 14, and a holder 16 (see Fig. 3). Fig. 1 also illustrates a pallet 22 on which the package 10 is placed.

[0025] (Outer box) 2, the exterior box 12 has a plate-shaped exterior bottom 12A and a plate-shaped exterior side wall 12B rising from an edge of the exterior bottom 12A. As shown in Fig. 3, in the exterior side wall 12B, a first portion 12B1 including the holding portion 16 protrudes upward from a second portion 12B2 in which the holding portion 16 is not provided.

[0026] The outer box 12 of the present embodiment can be made of, for example, cardboard, which is a paper material, but is not limited to this in the present disclosure. The material of the outer box of the present disclosure can be selected arbitrarily, for example, a resin material, etc.

[0027] (buffer material) As shown in Fig. 4, the cushioning material 14 has a plate-shaped cushioning bottom 14A that is placed on the exterior bottom 12A and supports the underside 20A of the packaged item 20, and a plate-shaped cushioning side wall 14B that rises from the edge of the cushioning bottom 14A and supports the side surface 20B of the packaged item 20. Fig. 4 illustrates a state in which a broken portion 14D is formed in the cushioning material 14 due to separation at a boundary portion 14C caused by, for example, an impact when dropped.

[0028] The cushioning material 14 of the present embodiment can be made of, for example, Expanded Polystyrene (EPS) material, but is not limited to this in the present disclosure. The material of the cushioning material of the present disclosure can be selected arbitrarily, for example, rubber.

[0029] In this specification, the buffer bottom corresponds to the portion on which the packaged items are loaded, and the buffer side wall corresponds to the portion located outside the buffer bottom. In other words, the outer surface of the buffer side wall corresponds to the entire outer surface of the buffer material.

[0030] (holding part) 4, the retaining portion 16 retains the relative position of the buffer side wall 14B with respect to the exterior side wall 12B. In this embodiment, the retaining portion 16 is disposed at a position equal to or higher than the boundary height HB between the upper surface of the buffer bottom portion 14A and the inner surface of the buffer side wall 14B. Note that the present disclosure is not limited to this, and it is sufficient that at least a part of the retaining portion 16 is disposed at a position equal to or higher than the boundary height HB between the upper surface of the buffer bottom portion 14A and the inner surface of the buffer side wall 14B.

[0031] The holding portion 16 has an exterior side fitting portion provided on the exterior side wall 12B and a buffer side fitting portion provided on the buffer side wall 14B corresponding to the exterior side fitting portion. Specifically, in this embodiment, the exterior side fitting portion is a hole portion 16A formed in the exterior side wall 12B, and the buffer side fitting portion is a protrusion portion 16B formed on the buffer side wall 14B corresponding to the hole portion 16A. The fitting may be configured to be detachable, or the fitted state may be fixed by, for example, an adhesive or the like.

[0032] In addition, in the present disclosure, for example, the protrusion 16B may be formed on the exterior side wall 12B, and the hole 16A corresponding to the protrusion 16B may be formed on the buffer side wall 14B. In addition, in the present embodiment, the shape of the protrusion 16B is a quadrangular prism, but in the present disclosure, the shape is not limited to this and may be any geometric shape, such as a cylindrical shape, a triangular prism shape, or a pyramidal truncated shape. In addition, in the present embodiment, the shape of the hole 16A is a through hole, but in the present disclosure, the shape is not limited to this and may be other shapes, such as a notch. Note that the larger the area of ​​the fitting portion between the protrusion and the hole, i.e., the area of ​​the contact portion of the protrusion on the inner surface of the hole, the more preferable it is in that the protrusion is less likely to come out of the hole.

[0033] As shown in Figs. 3 and 4, the exterior side wall 12B has a thick portion above the hole 16A as a suppression portion 18 that suppresses the projection 16B from coming off.

[0034] <How to transport the package> Next, a method for transporting a package using the package 10 according to this embodiment will be described. A transporter of the package first stores the packaged object 20 inside the package 10 of this embodiment. Next, the transporter makes the cushioning material 14 support the packaged object 20 in the package 10 with the packaged object 20 stored inside. Specifically, the cushioning bottom 14A supports the bottom surface 20A of the packaged object 20, and the cushioning side wall 14B supports the side surface 20B of the packaged object 20.

[0035] Then, the transporter transports the package 10 with the packaged object 20 supported by the cushioning material 14. The above series of steps constitutes the method for transporting a package according to this embodiment.

[0036] 5 illustrates a contact surface 14B1 formed on the inner surface of the buffer side wall 14B of this embodiment at a position equal to or higher than the boundary height of the boundary portion 14C. The contact surface 14B1 of the buffer side wall 14B of the buffer material 14 comes into contact with the packaged object 20. The larger the contact area with the packaged object 20, the more likely the buffer material 14 is to crack at the boundary portion 14C due to, for example, an impact when dropped during transportation, i.e., separation is more likely to occur.

[0037] Furthermore, the thinner the buffer side wall 14B, the easier it is for the buffer material 14 to separate. Furthermore, the higher the height of the buffer side wall 14B, the easier it is for the buffer material 14 to separate. For example, when the thickness and height of the buffer side wall 14B are approximately the same, the larger the contact area of ​​the contact surface 14B1 that comes into contact with the packaged item 20, the easier it is for the buffer material 14 to separate. In this embodiment, even if the buffer material 14 separates, the retaining portion 16 retains the relative position of the buffer side wall 14B with respect to the exterior side wall 12B.

[0038] (Action of this embodiment) In the packaging body 10 according to the present embodiment, the retaining portion 16 retains the relative position of the buffer side wall 14B with respect to the exterior side wall 12B, so that even if the buffer side wall 14B of the buffer material 14 is separated from the buffer bottom portion 14A, the retaining portion 16 suppresses the movement of the side wall of the buffer material 14. Therefore, the position where the buffer material 14 was arranged in the exterior box 12 before separation is easily maintained even after separation. Therefore, compared to the case where the exterior side wall 12B of the exterior box 12 and the buffer side wall 14B of the buffer material 14 are only in surface contact, even if the buffer side wall 14B is separated from the buffer bottom portion 14A of the buffer material 14, it is possible to suppress the deterioration of the posture-retaining function of the packaged object 20 and the deterioration of the shock-absorbing function of the buffer material 14.

[0039] In addition, in this embodiment, the holding portion 16 can prevent an increase in the thickness of the cushioning material 14 intended to prevent breakage, making it easier to reduce the thickness of the cushioning material 14 and the amount of material used.

[0040] In this embodiment, the entire retaining portion 16 is disposed at a position equal to or higher than the boundary height HB between the upper surface of the buffer bottom portion 14A and the inner surface of the buffer side wall 14B. The boundary between the upper surface of the buffer bottom portion 14A and the inner surface of the buffer side wall 14B is a position where separation is likely to start. Therefore, even if separation occurs at the boundary portion 14C, the deterioration of the movement suppression function of the separated buffer side wall 14B can be suppressed compared to when the retaining portion 16 is disposed at the height of the bottom portion.

[0041] In the present embodiment, in the exterior side wall 12B, the first portion 12B1 including the retaining portion 16 protrudes upward from the second portion 12B2 not provided with the retaining portion 16. Therefore, the amount of the flesh of the exterior side wall 12B used can be reduced compared to a case in which the height of the second portion 12B2 not provided with the retaining portion 16 in the exterior side wall 12B is aligned with the height of the first portion 12B1 including the retaining portion 16.

[0042] Moreover, the holding portion 16 of this embodiment has a hole portion 16A as an exterior side fitting portion, and a protrusion portion 16B as a buffer side fitting portion provided corresponding to the exterior side fitting portion.

[0043] Here, for example, when the holding portion 16 is formed by adhesive, a process of applying the adhesive and a process of drying the adhesive are required. Also, when the exterior box 12 and the cushioning material 14 are integrated with tape, a process of attaching the tape during the packing work and a process of removing the tape during the unpacking work are required. Since a fitting structure is used in this embodiment, the holding portion 16 can be configured more simply than when the holding portion 16 is formed by adhesive or when the exterior box 12 and the cushioning material 14 are integrated with tape.

[0044] In this embodiment, the exterior fitting portion is a hole 16A formed in the exterior side wall 12B, and the buffer fitting portion is a protrusion 16B formed in the buffer side wall 14B corresponding to the hole 16A. That is, the holding portion 16 can be formed only by the exterior box 12 and the buffer material 14. Therefore, it is possible to suppress the cost of parts and reduce the number of work steps compared to a case where the holding portion 16 is formed using a separate part other than the exterior box 12 and the buffer material 14. Note that the present disclosure does not exclude the holding portion 16 being formed using a separate part other than the exterior box 12 and the buffer material 14.

[0045] In this embodiment, the exterior side wall 12B has a thick portion serving as a suppression portion 18 that suppresses the protrusion 16B from slipping out above the hole 16A. Therefore, the thick portion serving as the suppression portion 18 can suppress the protrusion 16B from slipping out upward, compared to when the hole 16A is a notch that opens to the upper part of the exterior side wall 12B.

[0046] Furthermore, in the method for transporting the package 10 according to this embodiment, even if the buffer side wall 14B of the buffer material 14 is separated from the buffer bottom 14A, the retaining portion 16 prevents the side wall of the buffer material 14 from moving. Therefore, the position of the buffer material 14 in the exterior box 12 before separation can be easily maintained even after separation. Therefore, even if the buffer side wall 14B is separated from the buffer bottom 14A of the buffer material 14, it is possible to prevent a decrease in the posture-maintaining function of the packaged object 20 and a decrease in the shock-absorbing function of the buffer material 14, compared to a case in which the exterior side wall 12B of the exterior box 12 and the buffer side wall 14B of the buffer material 14 are only in surface contact with each other.

[0047] First Modified Example Next, the configuration of the packaging body 10A according to the first modified example will be described with reference to FIG. 6. As shown in FIG. 6, the packaging body 10A according to the first modified example differs from the packaging body 10 according to the present embodiment in that a gap G is formed below the lower edge 16B1 of the protruding portion 16B. Other configurations in the first modified example are common to the corresponding configurations in the present embodiment, and therefore redundant description will be omitted. Also, parts in the first modified example that are configured in the same way as in the present embodiment may be given the same reference numerals and description thereof will be omitted.

[0048] 6, the width of hole 16A measured in the vertical direction is longer than the width of protrusion 16B measured in the vertical direction. Before buffer bottom 14A supports bottom surface 20A of article 20, gap G is formed between lower edge 16A1 of hole 16A and lower edge 16B1 of protrusion 16B.

[0049] (Function of the First Modified Example) In the first modified example as in the present embodiment, even if the buffer side wall 14B is separated from the buffer bottom 14A of the buffer material 14, it is possible to suppress the deterioration of the posture-maintaining function of the packaged item 20 and the deterioration of the shock-absorbing function of the buffer material 14, compared to the case where the exterior side wall of the outer box and the buffer side wall 14B of the buffer material 14 are simply in surface contact with each other.

[0050] In addition, in the first modification, when the package 10 is subjected to an impact such as a drop, the protrusion 16B is distorted downward, i.e., the relative position between the protrusion 16B and the hole 16A changes in the vertical direction. Therefore, if the gap G is not formed, a load is generated on the portion of the exterior side wall 12B around the hole 16A and the protrusion 16B, and as a result, there is a concern that the protrusion 16B or the exterior side wall 12B may be damaged. In the first modification, the gap G absorbs the downward displacement of the protrusion 16B, so that damage to the protrusion 16B or the exterior side wall 12B can be suppressed compared to when the lower edge 16A1 of the hole 16A and the lower edge 16B1 of the protrusion 16B are in contact with each other.

[0051] Second Modified Example Next, the configuration of the packaging body according to the second modified example will be described with reference to FIG. 7. As shown in FIG. 7, the packaging body 10B according to the second modified example differs from this embodiment in that the holding portion 16 has a return portion 16B2 provided at the lower portion on the outer side (right side in FIG. 7) of the protruding portion 16B. Other configurations in the second modified example are common to the corresponding configurations in this embodiment, so duplicated explanations will be omitted. Also, parts in the second modified example that are configured in the same way as in this embodiment may be given the same reference numerals and explanations will be omitted.

[0052] As shown in Fig. 7, the turned portion 16B2 extends downward from the protruding portion 16B toward the exterior bottom portion 12A. The lower end of the turned portion 16B2 in Fig. 7 overlaps with the upper portion of the exterior side wall 12B in the inner / outer direction (the left / right direction in Fig. 7). The vertical width of the hole 16A is wide enough to allow the turned portion 16B2 to be inserted therethrough.

[0053] (Function of the second modified example) In the second modified example as in the present embodiment, even if the buffer side wall 14B is separated from the buffer bottom 14A of the buffer material 14, it is possible to suppress the deterioration of the posture-maintaining function of the packaged object and the deterioration of the shock-absorbing function of the buffer material 14, compared to the case where the exterior side wall of the exterior box 12 and the buffer side wall 14B of the buffer material 14 are simply in surface contact.

[0054] In the second modified example, the return portion 16B2 improves the unity between the exterior box 12 and the cushioning material 14. The more the protruding portion 16B is distorted downward due to an impact such as a drop, the longer the overlap length measured in the up-down direction between the return portion 16B2 and the exterior side wall 12B becomes. Therefore, the unity between the exterior box 12 and the cushioning material 14 can be further improved when the protruding portion 16B is distorted downward.

[0055] Third Modification Next, the configuration of the packaging body according to the third modified example will be described with reference to Fig. 8. As shown in Fig. 8, the packaging body 10C according to the third modified example differs from this embodiment in that a plug member 16D, which is a separate part other than the outer box 12 and the cushioning material 14, is used as a member constituting the holding part 16. The other configurations in the third modified example are common to the corresponding configurations in this embodiment, so duplicated explanations will be omitted. Also, the same reference numerals may be used to designate parts in the third modified example that are configured in the same way as in this embodiment, and explanations may be omitted.

[0056] As shown in FIG. 8, the holding portion 16 is composed of a hole 16A formed in the exterior side wall 12B, a hole 16C formed in the buffer side wall 14B, and a plug member 16D. For example, the hole 16A is circular. The hole 16C is a bottomed depression having a circular opening edge the same shape as the hole 16A. The plug member 16D is cylindrical with a height equal to or greater than the sum of the thickness of the exterior side wall 12B at the position of the hole 16A and the depth of the hole 16C. In the present disclosure, when the holding portion is composed of a hole formed in the exterior side wall, a hole formed in the buffer side wall, and a plug member, the shapes of each of the hole and the plug member can be changed arbitrarily.

[0057] (Function of the Third Modified Example) In the third modified example as well, as in the present embodiment, even if the buffer side wall 14B is separated from the buffer bottom 14A of the buffer material 14, it is possible to suppress the deterioration of the posture-maintaining function of the packaged object and the deterioration of the shock-absorbing function of the buffer material 14, compared to the case where the exterior side wall of the exterior box 12 and the buffer side wall 14B of the buffer material 14 are only in surface contact. Furthermore, as in the third modified example, in the present disclosure, the configuration of the holding portion 16 can be diversified. As a result, for example, the configuration of the return portion 16B2 of the second modified example can be easily produced.
