[0030] The packaging 10 is used to package a product 12. The packaging 10 is a concept that includes the product 12 as a component. Specifically, as shown in FIG. 1, the packaging 10 includes the product 12 and cushioning material 13. Furthermore, as shown in FIG. 2, the packaging 10 includes a box 20 and cushioning material 15. Each part of the packaging 10 will be described below. Packaging refers to wrapping the product 12 to prepare it for transportation, storage, sale, etc.
[0031] <Product 12> The product 12 is an object to be packaged. The product 12 is an article made of a certain material. As shown in FIG. 1 , the product 12 has a top surface 12U, a bottom surface 12D, a front surface 12F, a rear surface 12B, a right surface 12R, and a left surface 12L. The top surface 12U, the bottom surface 12D, the front surface 12F, the rear surface 12B, the right surface 12R, and the left surface 12L are surfaces facing upward, downward, forward, backward, right, and left, respectively. The front surface 12F, the rear surface 12B, the right surface 12R, and the left surface 12L are examples of side surfaces. In this embodiment, the product 12 has a recess 14 in a portion of the left surface 12L.
[0032] The recess 14 is a portion recessed to the right from the left surface 12L. The recess 14 is recessed in the vertical middle of the product 12. A portion 16 below the recess 14 protrudes to the left beyond the innermost surface 14D of the recess 14. Because the portion 16 protrudes in this manner, the innermost surface 14D of the recess 14 cannot be supported by the bottom support 30D and left support 30L of the cushioning material 13, which will be described later.
[0033] The product 12 corresponds to, for example, a component part of an image forming apparatus that forms an image. Examples of the image forming apparatus include electrophotographic or inkjet printers. For example, in the case of an electrophotographic image forming apparatus, the component parts include units used in each process such as charging, exposure, development, transfer, and fixing.
[0034] 1, the product 12 is shown in a rectangular parallelepiped shape, but various shapes are possible. Each surface of the product 12 may have irregularities other than the recesses 14.
[0035] <Box 20> Fig. 2 is a front view showing a state in which the product 12 and cushioning materials 13, 15 are housed in the box 20 according to this embodiment. Fig. 3 is a front view showing a state in which the product 12 and cushioning materials 13, 15 are being housed in the box 20 according to this embodiment.
[0036] The box 20 is a container that houses the product 12. Specifically, the box 20 is a cardboard box. As shown in Figures 2 and 3, the box 20 has a bottom wall 20D, a right wall 20R, a left wall 20L, a rear wall 20B, a front wall (not shown), and a lid portion 22. The lid portion 22 has a right lid 22R and a left lid 22L.
[0037] The box 20 is opened at the top by opening the right lid 22R and the left lid 22L. In this state, the product 12 and the cushioning materials 13 and 15 are placed in the box 20 through the upper opening.
[0038] <Buffer material 13, 15> The buffer materials 13 and 15 are used to absorb shocks caused by drops, vibrations, collisions, etc. The buffer materials 13 and 15 may be made of foam materials such as polyethylene, polystyrene, and polypropylene.
[0039] As shown in FIG. 1, the cushioning material 13 is formed in the shape of a box with a bottom and an open top. The cushioning material 15 is formed in the shape of a box that is open at the bottom and closed at the top. The cushioning material 13 supports the lower part of the product 12, including the bottom surface 12D. The cushioning material 15 covers the upper part of the product 12, including the upper surface 12U. As shown in FIG. 2, the cushioning material 15 is stacked on top of the cushioning material 13. The outer peripheral surface and the upper surface of the cushioning material 15 are provided with protrusions 17 that protrude outward. The protrusions 17 come into contact with the inner surface of the box 20.
[0040] The specific configuration of the cushioning material 13 will be described below. FIG. 4 is a plan view of the cushioning material 13 when a movable part 40 (described later) is located at a first position. FIG. 5 is a front cross-sectional view (specifically, a cross-sectional view taken along line AA in FIG. 4) of the cushioning material 13 when a movable part 40 (described later) is located at a first position. FIG. 6 is a plan view of the cushioning material 13 when a movable part 40 (described later) is located at a second position. FIG. 7 is a front cross-sectional view (specifically, a cross-sectional view taken along line BB in FIG. 6) of the cushioning material 13 when a movable part 40 (described later) is located at a second position.
[0041] 1 and 4, the cushioning material 13 specifically includes a support member 30, a movable member 40, and a connecting member 50. The support member 30 is a component that supports the product 12 contained in the box 20. The support member 30 specifically includes a bottom support member 30D, a right support member 30R, a left support member 30L, a rear support member 30B, and a front support member 30F. The bottom support member 30D, the right support member 30R, the left support member 30L, the rear support member 30B, and the front support member 30F form the cushioning material 13 in a box shape.
[0042] The bottom support 30D contacts and supports the bottom surface 12D of the product 12. The bottom support 30D is formed in a plate shape with its thickness extending in the vertical direction. The top surface of the bottom support 30D may be formed with projections and depressions to match the shape of the bottom surface 12D.
[0043] The right support body 30R contacts and supports the right surface 12R of the product 12. The right support body 30R is formed in a plate shape with its thickness in the left-right direction. The left surface (i.e., the inner surface) of the right support body 30R may be formed with projections and depressions to match the shape of the right surface 12R.
[0044] The left support 30L is an example of a support portion. The left support 30L contacts and supports the left surface 12L of the product 12. The left support 30L is formed in a plate shape with its thickness in the left-right direction. The right surface (i.e., the inner surface) of the left support 30L may be formed with projections and depressions to match the shape of the left surface 12L.
[0045] The rear support 30B contacts and supports the rear surface 12B of the product 12. The rear support 30B is formed in a plate shape with its thickness in the front-to-rear direction. The front surface (i.e., the inner surface) of the rear support 30B may be formed with projections and depressions to match the shape of the rear surface 12B.
[0046] The front support 30F contacts and supports the front surface 12F of the product 12. The front support 30F is formed in a plate shape with its thickness in the front-to-rear direction. The rear surface (i.e., the inner surface) of the front support 30F may be formed with projections and depressions to match the shape of the front surface 12F.
[0047] The bottom support 30D, the right support 30R, the left support 30L, the rear support 30B, and the front support 30F each have a protrusion 33 that protrudes outward. The protrusion 33 comes into contact with the inner surface of the box 20.
[0048] The movable part 40 is provided on the left support body 30L. Specifically, the movable part 40 is disposed in a front portion of the left support body 30L. This movable part 40 is a component that can move into the recess 14 of the left surface 12L when the left support body 30L supports the left surface 12L. The movable part 40 is movable from a first position to a second position. In other words, the movable part 40 is movable in the left-right direction between the first position and the second position.
[0049] The first position is the position shown in Figures 4 and 5. In the first position, the movable part 40 is located outside the recess 14. Furthermore, in the first position, the movable part 40 protrudes outward beyond the outer surface 30X of the left support body 30L. In other words, in the first position, the outer surface 40X of the movable part 40 is disposed on the left side of the outer surface 30X. The outer surface 30X is the outermost (specifically, leftmost) surface of the left support body 30L. The outer surface 40X is the outermost (specifically, leftmost) surface of the movable part 40.
[0050] The second position is the position shown in Figures 6 and 7. In the second position, the movable part 40 enters the recess 14. In the second position, the movable part 40 does not protrude outward beyond the outer surface 30X of the left support body 30L. In other words, in the second position, the outer surface 40X of the movable part 40 is positioned along the outer surface 30X. Specifically, in the second position, the outer surface 40X of the movable part 40 and the outer surface 30X are positioned on the same plane.
[0051] The movable part 40 may be supported by the support 30 (e.g., bottom support 30D) at the second position. The movable part 40 may also be supported by the support 30 (e.g., bottom support 30D) at the first position. Furthermore, the movable part 40 may be positioned by contacting the support 30 (e.g., bottom support 30D) at the second position. That is, the movable part 40 may be limited in its movement to the right by contacting the support 30 (e.g., bottom support 30D) at the second position.
[0052] The movable part 40 is formed in a generally block shape (specifically, a generally rectangular parallelepiped shape). The movable part 40 has an entry part 41 and a contact surface 42. The entry part 41 is a part that enters the recessed part 14 of the product 12 when the movable part 40 is located in the second position. This entry part 41 comes into contact with the inner surface 14D of the recessed part 14 when the movable part 40 is located in the second position.
[0053] As shown in Fig. 3, the contact surface 42 comes into contact with the box 20 when the cushioning material 13 is placed in the box 20, and functions to move the movable part 40 from the first position to the second position. The contact surface 42 is formed on the diagonally lower left side of the movable part 40. The contact surface 42 is an inclined surface facing diagonally lower left. Specifically, the contact surface 42 comes into contact with the ridge portion 24 of the box 20, thereby moving the movable part 40 to the second position.
[0054] The connecting part 50 is a component that connects the left support body 30L and the movable part 40. The connecting part 50 deforms itself to allow the movable part 40 to move into the recess 14. Furthermore, the connecting part 50 also functions as an acting part that applies a force (hereinafter referred to as a moving force) that moves the movable part 40 out of the recess 14. The connecting part 50 is made of the same material as the cushioning material 13 and is formed integrally with the cushioning material 13.
[0055] The connecting portion 50 has a pair of arms 52. The pair of arms 52 connect the front end and rear end of the movable portion 40 to the left support body 30L, respectively. The front end and rear end are examples of one end and the other end in a direction intersecting the movement direction (specifically, the front-to-rear direction). The pair of arms 52 are formed in an arc shape in a plan view. The pair of arms 52 exert a movement force by their own elastic force. As a result, the movable portion 40 is positioned at the first position in an unloaded state where it is not subjected to an external force.
[0056] <Actions according to this embodiment> According to this embodiment, the movable part 40 is movable into the recess 14 of the left surface 12L while the left support body 30L supports the left surface 12L of the product 12. This eliminates the need to attach a separate member to the recess 14 before attaching the cushioning material 13 to the product 12.
[0057] According to this embodiment, the left support body 30L and the movable part 40 are connected by the connecting part 50, which deforms to allow the movable part 40 to move into the recess 14. Therefore, compared to when the cushioning material 13 includes only the left support body 30L and the movable part 40, separation of the movable part 40 from the left support body 30L is suppressed.
[0058] According to this embodiment, the connecting portion 50 has a pair of arms 52 that connect the front end and rear end of the movable portion 40 to the left support body 30L, respectively. Therefore, separation of the movable portion 40 from the left support body 30L is suppressed compared to when the movable portion 40 is connected to the left support body 30L at only one point.
[0059] According to this embodiment, the connecting portion 50 applies a moving force that moves the movable portion 40 out of the recess 14. Therefore, an operation to move the movable portion 40 out of the recess 14 is not required.
[0060] According to this embodiment, the pair of arms 52 exert a moving force by elastic force, which reduces the possibility of the movable part 40 moving out of the recess 14 compared to when the movable part 40 is connected to the left support body 30L at only one point.
[0061] According to this embodiment, the movable part 40 is movable from a first position where it protrudes outward from the outer surface 30X of the left support body 30L and is located outside the recess 14, to a second position where it enters the recess 14. Therefore, it is easier to apply an external force that moves the movable part 40 into the recess 14 than when the movable part 40 is always located at a position where it does not protrude outward from the outer surface 30X of the left support body 30L.
[0062] According to the present embodiment, the movable part 40 does not protrude outward beyond the outer surface 30X of the left support body 30L at the second position. Therefore, the movable part 40 is less likely to be an obstacle at the second position compared to when the movable part 40 protrudes outward beyond the outer surface 30X of the left support body 30L at the second position.
[0063] According to this embodiment, the movable part 40 is formed with a contact surface 42 that comes into contact with the box 20 when the cushioning material 13 is placed in the box 20, and moves the movable part 40 from the first position to the second position. Therefore, an operation to move the movable part 40 into the recess 14 is not required.
[0064] <Modification> In the present embodiment, the connecting part 50 has a pair of arms 52 that connect the front end and rear end of the movable part 40 to the left support body 30L, respectively, but is not limited to this. For example, the connecting part 50 may be configured to connect only one point of the movable part 40 to the left support body 30L.
[0065] In the present embodiment, the connecting portion 50 also functions as an acting portion that applies a moving force to move the movable portion 40 out of the recess 14, but this is not limited to this. Apart from the connecting portion 50, a spring (for example, a compression spring or a tension spring) may be provided in the buffer material 13 as an acting portion.
[0066] In the present embodiment, one movable part 40 is provided on the left support 30L, but multiple movable parts 40 may be provided on the left support 30L in accordance with the number of recesses 14 of the product 12. Furthermore, instead of or in addition to the left support 30L, one or multiple movable parts 40 may be provided on any of the right support 30R, rear support 30B, and front support 30F in accordance with the number and positions of the recesses 14 of the product 12. Specifically, for example, as shown in FIG. 8, in addition to the movable part 40 provided on the left support 30L, a movable part 40 may be provided on the right support 30R. In the configuration shown in FIG. 8, the movable part 40 is disposed on the rear side of the right support 30R.
[0067] The present invention is not limited to the above-described embodiment, and various modifications, changes, and improvements are possible without departing from the spirit of the present invention. For example, the above-described modified examples may be appropriately combined to form a configuration.
