  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the following embodiment is an example which actualized this invention, Comprising: It does not have the character which limits the technical scope of this invention.

[Waste toner unit 9]
First, the configuration of a waste toner unit 9 that is an example of a packaged product accommodated in the packaging container 1 according to the embodiment will be described with reference to FIGS. The waste toner unit 9 is a component attached to an electrophotographic color image forming apparatus.

  In addition, the waste toner unit 9 which is an example of the product to be packed and the packaging container 1 that accommodates the waste toner unit 9 form a packaging structure according to the embodiment.

  The color image forming apparatus is a tandem type image forming apparatus, and includes a plurality of image forming units for forming different color toner images. Each of the image forming units includes a rotating drum-shaped image carrier, an intermediate transfer belt, a developing unit, a primary cleaning unit, and a secondary cleaning unit.

  The image carrier is a photoreceptor on which an electrostatic latent image is formed. The developing unit develops the electrostatic latent image formed on the surface of the image carrier into a toner image. Each of the developing units includes a developing container that stores different colors of toner.

  The primary cleaning unit scrapes off the remaining waste toner from a portion of the surface of the image carrier after the toner image is transferred to the intermediate transfer belt.

  The secondary cleaning unit scrapes off the remaining waste toner from a portion of the intermediate transfer belt after the toner image is transferred to a sheet material such as paper.

  The waste toner unit 9 is a component that stores waste toner collected from the plurality of primary cleaning units, the plurality of developing units, and the secondary cleaning unit. The waste toner is recovered by suction of the waste toner scraped from the image carrier by the plurality of primary cleaning units and the toner floating in the developing container of the plurality of development units. And the waste toner scraped from the intermediate transfer belt by the secondary cleaning unit.

  The waste toner unit 9 includes a waste toner container 91, a gear mechanism 92, a stirring member 93, a first bearing 94, and a second bearing 95.

  The waste toner container 91 is a container for storing the waste toner collected from the image forming unit including a plurality of the developing units in the image forming apparatus. In the following description, the longitudinal direction of the waste toner unit 9 is referred to as a first longitudinal direction Dx1.

  Further, the first width direction Dx2 and the first height direction Dx3 mean the width direction and the height direction of the waste toner unit 9 when the packaging container 1 containing the waste toner unit 9 is handled. The first longitudinal direction Dx1, the first width direction Dx2, and the first height direction Dx3 are directions orthogonal to each other.

  When the waste toner unit 9 is mounted on the image forming apparatus, the first width direction Dx2 and the first height direction Dx3 are the height direction and the width direction of the waste toner unit 9, respectively. 1 to 3 show the waste toner unit 9 in a direction in which the first width direction Dx2 is a vertical direction, that is, a direction when the waste toner unit 9 is mounted on the image forming apparatus.

  In the following description, the directions of the lower surface 9b, the upper surface 9u, the first end surface 9f, the second end surface 9r, the first side surface 9v, and the second side surface 9w of the waste toner container 91 are also the waste toner contained in the packaging container 1. The orientation is based on the posture of the unit 9. The second side surface 9w is a surface of the waste toner container 91 opposite to the first side surface 9v.

  In a state where the waste toner container 91 is mounted on the image forming apparatus, the first side surface and the second side surface 9w of the waste toner container 91 are a lower surface and an upper surface, respectively.

  A plurality of first toner receiving ports 911 and a plurality of second toner receiving ports 912 are formed on the upper surface 9 u of the waste toner container 91.

  Each of the first toner receiving ports 911 is an opening that forms an entrance for the waste toner collected by each of the primary cleaning units. Each of the second toner receiving ports 912 is an opening that forms an entrance of the waste toner collected from each of the developing units.

  Further, a toner receiving duct 913 protrudes from the upper surface 9 u of the waste toner container 91. A third toner receiving port 914 is formed in the toner receiving duct 913. The third toner receiving port 914 is an opening that forms an entrance for the waste toner collected by the secondary cleaning unit.

  Further, an exhaust duct 915 projects from the first side surface 9v of the waste toner container 91. A ventilation fan provided in the image forming apparatus sucks air in the waste toner container 91 from the opening 916 of the exhaust duct 915.

  Therefore, the waste toner container 91 has a negative pressure. As a result, an air flow that flows from each of the developing portions to the exhaust duct 915 through each of the second toner receiving ports 912 is generated. The floating toner in each of the developing units is collected in the waste toner container 91 by the airflow.

  A dust absorption filter 917 is packed in the opening 916 of the exhaust duct 915. The dust suction filter 917 captures the waste toner that flows in the exhaust duct 915 in the air.

  The gear mechanism 92 is provided at the first end portion 9 x in the longitudinal direction of the waste toner container 91. The waste toner unit 9 is an example of a packaged product including a gear mechanism 92 at the first end 9x in the first longitudinal direction Dx1. In the waste toner unit 9, the end face of the first end 9x is the first end face 9f, and the end face of the second end 9y is the second end face 9r.

  As shown in FIG. 3, the stirring member 93 includes a rotating shaft 931 and a stirring blade 932. The rotation shaft 931 is connected to the gear mechanism 92 and is formed from the first end 9x of the waste toner container 91 to the second end 9y on the opposite side. The first longitudinal direction Dx1 is a direction along the rotation axis 931.

  The rotating shaft 931 is rotatably supported by a first bearing 94 and a second bearing 95 provided at the first end 9x and the second end 9y in the longitudinal direction of the waste toner container 91. The second end portion 9y of the waste toner unit 9 is not provided with a mechanism that is vulnerable to impact, such as a link mechanism and a gear mechanism.

  The first end portion 9x and the second end portion 9y of the waste toner container 91 are also both end portions of the waste toner unit 9 in the first longitudinal direction Dx1. Further, the lower surface 9b, the upper surface 9u, the first end surface 9f, the second end surface 9r, the first side surface 9v, and the second side surface 9w of the waste toner container 91 are the lower surface 9b, the upper surface 9u, and the first end surface 9f of the waste toner unit 9, respectively. It can also be said that they are the second end face 9r, the first side face 9v and the second side face 9w.

  The rotation shaft 931 rotates in conjunction with the driving of the gear mechanism 92. The stirring blade 932 is formed to project outward from the outer peripheral surface of the rotating shaft 931. The stirring blade 932 rotates around the rotation shaft 931 as the rotation shaft 931 rotates. The rotating stirring blade 932 stirs the waste toner in the waste toner container 91. As a result, the waste toner is dispersed and accumulated in the waste toner container 91.

[Outline of packing container 1]
The waste toner unit 9 circulates while being accommodated in the packaging container 1. The packaging container 1 is formed of a buffering plate material such as cardboard.

  As shown in FIG. 4, the packaging container 1 has a rectangular parallelepiped box portion 2. In FIG. 1, the packaging container 1 is indicated by a virtual line.

  Furthermore, the packaging container 1 includes a buffer unit interposed between the waste toner unit 9 that is a packaged product and the inner surface of the box unit 2. Details of the buffer section will be described later.

  The box part 2 and the buffer part of the packing container 1 are crushed according to the external force received by the packing container 1 due to dropping or the like, thereby reducing the impact transmitted to the waste toner unit 9.

  Incidentally, the packaged object may include a gear mechanism 92 and a rotating body driven by the gear mechanism 92 like the waste toner unit 9 in some cases. The stirring member 93 is an example of the rotating body.

  As described above, the gear mechanism 92 is provided at the first end portion 9x in the longitudinal direction of the waste toner unit 9, and one of the pair of bearings 94, 95 of the stirring member 93 is connected to the second end portion 9y of the waste toner unit 9. Provided. The gear mechanism 92 is relatively weak against impact, and the bearings 94, 95, etc. are relatively less affected by impact.

  On the other hand, the packaging container 1 is required to be able to reduce the amount of material used as much as possible while ensuring necessary buffering properties.

  If the packaging container 1 is employed, it is possible to reduce the amount of material used as much as possible while ensuring the buffering property necessary for accommodating the waste toner unit 9 including the gear mechanism 92 at one end. A typical example of the material of the packaging container 1 is cardboard.

[Details of configuration of packing container 1]
The packaging container 1 is assembled by bending a single cushioning plate shown in FIG. 7 and bonding a part thereof.

  In FIG. 7, the solid line represents the outer shape of the plate material and the slit formed in the plate material. Moreover, the hatched portion is an opening formed in the plate material. Further, in the plate material, the one-dot broken line in FIG. 7 is a line to be a valley fold, and the two-dot broken line is a line to be a mountain fold. In FIG. 7 and FIGS. 5 and 6, parts corresponding to each other are denoted by the same reference numerals.

  As shown in FIG. 5, the packaging container 1 includes a box part 2 and a first end lower surface support part 3. The box portion 2 is a rectangular parallelepiped portion that accommodates the waste toner unit 9. The box portion 2 includes a bottom plate portion 2b, a top plate portion 2u, a first side plate portion 2f, a second side plate portion 2v, a third side plate portion 2r, and a fourth side plate portion 2w.

  In the following description, the longitudinal direction of the box portion 2 is referred to as a second longitudinal direction Dy1. The second longitudinal direction Dy1 is a direction along the long sides of the bottom plate portion 2b and the top plate portion 2u. The second width direction Dy2 and the second height direction Dy3 mean the width direction and the height direction of the box part 2, respectively. The second longitudinal direction Dy1, the second width direction Dy2, and the second height direction Dy3 are directions orthogonal to each other.

  The first side plate portion 2f forms a first end in the second longitudinal direction Dy1 in the box portion 2, and the third side plate portion 2r forms a second end in the second longitudinal direction Dy1 in the box portion 2.

  Further, the second side plate portion 2v forms a first end in the second width direction Dy2 in the box portion 2, and the fourth side plate portion 2w forms a second end in the second width direction Dy2 in the box portion 2.

  In the present embodiment, the bottom plate portion 2b, the second side plate portion 2v, the top plate portion 2u, and the fourth side plate portion 2w are formed in a rectangular tube shape. In the plate shown in FIG. 7, the margin 7 connected to the second side plate portion 2 v and the fourth side plate portion 2 w are bonded. Thereby, a rectangular tube-shaped part is formed. And the 1st side board part 2f and the 3rd side board part 2r form the lid | cover which closes the opening of the both ends of a square cylindrical part.

  As shown in FIG. 5, the first end portion lower surface support portion 3 is a portion that supports the first end portion 9 x of the waste toner unit 9 from below. The first end lower surface support portion 3 is located between the bottom plate portion 2b and the lower surface of the first end portion 9x of the waste toner unit 9 at a position near the first side plate portion 2f of the box portion 2 in the second longitudinal direction Dy1. A buffer space 82 is formed. The position of the box part 2 near the first side plate part 2f is a position near the first end in the second longitudinal direction Dy1.

  A part of the bottom plate portion 2b of the box portion 2 forms a second end lower surface support portion 2b1. The second end lower surface support portion 2b1 is a portion near the second end in the second longitudinal direction Dy1 in the bottom plate portion 2b. The second end lower surface support 2b1 supports the second end 9y of the waste toner unit 9 from below.

  The first end lower surface support portion 3 and the second end lower surface support portion 2b1 are provided between the portion between the first end portion 9x and the second end portion 9y on the lower surface 9b of the waste toner unit 9 and the bottom plate portion 2b. The waste toner unit 9 is supported in a state in which the gap 81 is generated.

  Further, the first end lower surface support portion 3 and the second end lower surface support portion 2b1 support the waste toner unit 9 in a state where the first longitudinal direction Dx1 is inclined in the vertical direction with respect to the second longitudinal direction Dy1. . In other words, the buffer portion for supporting the first longitudinal direction Dx1 in the longitudinal direction in parallel with the second longitudinal direction Dy1 is omitted.

  Generally, the product to be packed is accommodated in the packing container in a state in which the longitudinal direction thereof is parallel to the longitudinal direction of the packing container. In this case, a buffer material interposed between the bottom plate portion 2b and the lower surface 9b of the waste toner unit 9 is required as the second end lower surface support portion 2b1.

  On the other hand, in the present embodiment, the waste toner unit 9 is accommodated in the packaging container 1 in a state where the first longitudinal direction Dx1 is inclined in the vertical direction with respect to the second longitudinal direction Dy1. This point is different from the conventional packaging structure.

  According to the present embodiment, it is possible to reduce the amount of use of the buffer material as much as possible while ensuring the buffer property necessary for housing the waste toner unit 9 including the gear mechanism 92 at one end. Moreover, the external dimension of the packaging container 1 can be made small and a storage space can be reduced.

  Further, a toner receiving duct 913 that protrudes from the other portion is formed on the upper surface 9 u of the waste toner unit 9 at a position near the second end portion 9 y. The toner receiving duct 913 is an example of a first protrusion.

  Even if the first end lower surface support portion 3 holds the first end portion 9x of the waste toner unit 9 at a position away from the bottom plate portion 2b, the height of the toner receiving duct 913 hardly changes. Therefore, even if the first end lower surface support portion 3 is provided, the outer shape of the packaging container 1 is hardly increased as compared with the case where the first end lower surface support portion 3 does not exist. This point also contributes to the suppression of the use amount of the buffer material.

  As shown in FIG. 5, the packaging container 1 further includes a first end surface buffer portion 4 and a second end surface buffer portion 5.

  The first end surface buffer portion 4 is a portion that forms a buffer space 83 between the first end surface 9f of the waste toner unit 9 and the first side plate portion 2f facing the first end surface 9f. Similarly, the second end surface buffer portion 5 is a portion that forms a buffer space 84 between the second end surface 9r of the waste toner unit 9 and the third side plate portion 2r facing the second end surface 9r.

  In this embodiment, the 1st end part lower surface support part 3 is formed of the part which connects the baseplate part 2b and the 1st end surface buffer part 4 in the said board | plate material of a shock absorbing property. Accordingly, it is possible to reduce the number of the plate members included in the assembly of the packaging container 1. In the present embodiment, the packaging container 1 is formed by the single plate material shown in FIG.

  As shown in FIG. 5, the first end lower surface support portion 3 includes a folded portion 31, an upright portion 33, and a connecting portion 35. The folded portion 31 is a portion that is continuous with the bottom plate portion 2b and folded along the bottom plate portion 2b.

  The standing portion 33 is a portion that stands up from the folded portion 31. The standing portion 33 is connected to the folded portion 31 and forms a first bent portion 32 at the boundary with the folded portion 31.

  The connecting portion 35 is a portion that continues to the upright portion 33 and the first end surface buffer portion 4. The connecting portion 35 forms a second bent portion 34 at the boundary with the upright portion 33.

  At least the second bent portion 34 of the second bent portion 34 and the connecting portion 35 supports the lower surface of the first end portion 9 x of the waste toner unit 9. In the present embodiment, a portion extending from the second bent portion 34 to the connecting portion 35 supports the lower surface 9 b of the waste toner unit 9. A space formed by a portion extending from the standing portion 33 to the connecting portion 35 is a buffer space 82.

  Further, the first end face buffering portion 4 includes a first facing portion 42 and a first spacer portion 44. The first facing portion 42 is a portion facing the first end surface 9 f of the waste toner unit 9. The first facing portion 42 is continuous with the connecting portion 35 and forms a third bent portion 41 at the boundary with the connecting portion 35.

  The first spacer portion 44 is a portion that is continuous with the first facing portion 42 and is sandwiched between the first facing portion 42 and the first side plate portion 2 f of the box portion 2. The first spacer portion 44 forms a fourth bent portion 43 at the boundary with the first facing portion 42. A space formed by the first spacer portion 44 between the first facing portion 42 and the first side plate portion 2 f is a buffer space 83 of the first end surface buffer portion 4.

  On the other hand, the second end surface buffer portion 5 includes a second spacer portion 51, a second facing portion 53, and a third spacer portion 55. The second spacer portion 51 is a portion that is folded back from the bottom plate portion 2 b of the box portion 2 along the bottom plate portion 2 b. That is, the second spacer portion 51 is continuous with the bottom plate portion 2b.

  The second facing portion 53 is a portion facing the second end surface 9 r of the waste toner unit 9. The second facing portion 53 is continuous with the second spacer portion 51, and forms a fifth bent portion 52 at the boundary with the second spacer portion 51.

  The third spacer portion 55 is a portion that is connected to the second facing portion 53 and is sandwiched between the second facing portion 53 and the third side plate portion 2 r of the box portion 2. The third spacer portion 55 forms a sixth bent portion 54 at the boundary with the second facing portion 53. A space formed between the second facing portion 53 and the third side plate portion 2r by the second spacer portion 51 and the third spacer portion 55 is a buffer space 84 of the second end surface buffer portion 5.

  Moreover, as FIG. 6 shows, the packaging container 1 is further provided with the 1st side surface buffer part 6. As shown in FIG. The first side buffer portion 6 is a portion interposed between the portion near the second end in the second longitudinal direction Dy1 in the second side plate portion 2v of the box portion 2 and the first side surface 9v of the waste toner unit 9. is there.

  In this embodiment, the 1st side surface buffer part 6 is the part folded along the 2nd side board part 2v from the 2nd side board part 2v of the box part 2. As shown in FIG. That is, the 1st side surface buffer part 6 is continued to the 2nd side board part 2v.

  The first side surface 9v of the waste toner unit 9 is a side surface on the second side plate portion 2v side of the box portion 2 among a pair of side surfaces forming both ends of the waste toner unit 9 in the first width direction Dx2.

  A joining portion 918 joined by welding is formed at an edge along the first longitudinal direction Dx1 of the first side surface 9v of the waste toner unit 9. The joint part 918 is a part joined by ultrasonic welding.

  When the joint portion 918 as described above receives an impact at the portion between the first end portion 9x and the second end portion 9y, the joint may be disconnected. Therefore, regarding the first side surface 9v of the waste toner unit 9, it is desirable that the packaging container 1 supports the first end portion 9x and the second end portion 9y that are relatively resistant to impact.

  An exhaust duct 915 that protrudes from other portions is formed at a position near the first end 9x on the second side surface 9w of the waste toner unit 9. The exhaust duct 915 is an example of a second protrusion. The first end 9x of the waste toner unit 9 is an example of a quasi first end. The second end 9y of the waste toner unit 9 is an example of a quasi second end.

  Here, the portion of the second side plate portion 2v that faces the first end portion 9x of the waste toner unit 9 is referred to as a first side surface contact portion 2v1.

  The first side buffer portion 6 and the first side contact portion 2v1 are provided between the portion between the first end portion 9x and the second end portion 9y on the first side surface 9v of the waste toner unit 9 and the second side plate portion 2v. The first side surface 9v of the waste toner unit 9 is supported in a state where the gap 85 is generated.

  Further, the first side buffer portion 6 and the first side contact portion 2v1 support the first side surface 9v of the waste toner unit 9 in a state where the first longitudinal direction Dx1 is inclined in the lateral direction with respect to the second longitudinal direction Dy1. . In other words, the buffer portion for making the first longitudinal direction Dx1 parallel to the second longitudinal direction Dy1 in the lateral direction is omitted. This contributes to a reduction in the amount of buffer material used.

  Furthermore, according to the present embodiment, a portion that is vulnerable to impact at the joint portion 918, that is, a portion between the first end portion 9x and the second end portion 9y in the joint portion 918 is in relation to the second side plate portion 2v. Do not touch directly. Therefore, the joint portion 918 is appropriately protected.

  Moreover, the 1st side surface buffer part 6 is provided in the opposite side with respect to the side in which the exhaust duct 915 is formed in 1st longitudinal direction Dx1. For this reason, even if the first side buffer 6 holds the second end 9y of the waste toner unit 9 at a position away from the second side plate 2v, the position of the exhaust duct 915 hardly changes. Therefore, even if the 1st side surface buffer part 6 is provided, the external shape of the packaging container 1 does not become large compared with the case where the 1st side surface buffer part 6 does not exist. This point also contributes to the suppression of the use amount of the buffer material. Moreover, the external dimension of the packaging container 1 can be made small and a storage space can be reduced.

  In addition, on the 2nd side surface 9w of the waste toner container 91, the case where the exhaust duct 915 is formed in the position close | similar to the 2nd edge part 9y in 2nd longitudinal direction Dy1 can be considered. In this case, the positional relationship in the first longitudinal direction Dx1 of the first side buffer portion 6 and the first side surface contact portion 2v1 is opposite to the positional relationship shown above.

  That is, when the exhaust duct 915 is formed at a position near the second end portion 9 y, the first side buffer portion 6 is formed at a position that supports the first end portion 9 x of the waste toner unit 9. Further, the first side surface contact portion 2v1 is a portion facing the second end portion 9y of the waste toner unit 9 in the second side plate portion 2v. In this case, the second end 9y of the waste toner unit 9 is an example of the quasi first end, and the first end 9x of the waste toner unit 9 is an example of the quasi second end. .

[Application example]
It is also conceivable that the structure of the packaging container 1 is applied to a packaging container that accommodates a packaged product other than the waste toner unit 9. For example, the packaged product may be a toner supply unit that stores the toner supplied to the developing unit in the image forming apparatus, or a developing unit that includes the image carrier, the developing unit, and the primary transfer unit. There is also a possibility. These units also include a gear mechanism at one end in the longitudinal direction and a bearing at the other end.

  The packaging container and the packaging structure according to the present invention can be freely combined with the above-described embodiments and application examples within the scope of the invention described in each claim, or the embodiments and application examples as appropriate. It is also possible to constitute by changing or omitting a part.
