Description

[Technical field]

[0001] The present disclosure relates to a package for housing a printing device and a cushioning material made of molded pulp. [Background technology]

[0002] Conventionally, a package for housing a printing device is known (see Patent Document 1). This package uses a pulp molded cushioning material as a cushioning material for protecting the main body of the printing device when transporting the device, etc. Pulp molded cushioning material is made from recycled raw materials such as waste paper, and since it can be recycled naturally without adversely affecting the environment, it has better environmental performance than polystyrene foam cushioning material.

[0003] [Patent Document 1] JP 2005-022680 A Summary of the Invention [Problem to be solved by the invention]

[0004] When transporting a printing device, it may be desirable to package the device body and the consumables separately in order to prevent damage to the printing device body and the consumables attached to the printing device body and to prevent deterioration of the consumables during transport. However, when the device body and the consumables are packaged separately, there are problems in that the package becomes large and it is difficult to adequately protect the device body and the consumables. In addition, it is difficult to mold pulp-molded cushioning materials so that they are thicker only in specific areas where cushioning is desired, making it difficult to adequately protect the device body without increasing the size of the package.

[0005] Therefore, an object of the present disclosure is to adequately protect the device body and consumables without increasing the size of the packaging body provided with pulp molded cushioning material. Another object of the present disclosure is to adequately protect the device body with a cushioning material made of molded pulp. [Means for solving the problem]

[0006] In order to solve the above problems, the package according to the present disclosure contains a printer body and consumables that are detachable from the printer body. The package includes an outer box, a top pad made of pulp mold, a bottom pad made of pulp mold, and a center pad made of pulp mold. The top pad is disposed between an upper portion of the device body and the outer case. The bottom pad is disposed between a lower portion of the device body and the outer case. The center pad is disposed between the top pad and the bottom pad in contact with the top pad and the bottom pad. The center pad has a holding portion that forms a recessed shape for holding the consumable.

[0007] The packaging body includes a top pad arranged on the top of the device body, a bottom pad arranged on the bottom of the device body, and a center pad for holding consumables. The center pad is arranged in contact with the top pad and the bottom pad, so that the packaging body as a whole can ensure cushioning, especially in the vertical direction. This ensures cushioning compared to a configuration in which the center pad is separated from the top pad or the bottom pad, or a configuration without a center pad, so that the respective cushioning materials can be made smaller. This makes it possible to protect both the device body of the printing device and the consumables without increasing the size of the packaging body. In addition, by holding the consumables on the center pad, the consumables can be positioned near the center in the vertical direction, so that the consumables can be appropriately protected.

[0008] The center pad may have a contact portion that contacts the top pad, and the contact portion may be located between the holder and the inner surface of the outer box in a first direction perpendicular to the up-down direction and closer to the inner surface of the outer box than the center of the outer box.

[0009] Since the center pad has a contact portion that comes into contact with the top pad outside the holding portion, the contact portion can protect the consumable held by the holding portion from the outside.

[0010] The center pad may have a plurality of contact portions, and the contact portions may be disposed on both sides of the holding portion in the first direction.

[0011] The top pad may have a first protruding portion protruding downward, and the center pad may have a second protruding portion protruding upward, and the contact portion may be provided at a tip end of the second protruding portion and may contact a tip end of the first protruding portion.

[0012] The tip of the first protrusion may have a first uneven surface, and the contact portion may have a second uneven surface, and the first uneven surface and the second uneven surface may be engaged with each other.

[0013] The tip of the first protrusion of the top pad has a first uneven surface, which increases the rigidity of the tip. Also, the contact portion of the center pad has a second uneven surface, which increases the rigidity of the contact portion. This allows the consumables to be appropriately protected.

[0014] The first uneven surface may have a stepped shape that becomes lower the further away from the holding portion in the first direction, and the second uneven surface may have a stepped shape that becomes lower the further away from the holding portion in the first direction.

[0015] Since both the first uneven surface and the second uneven surface have a stepped shape, they can be easily brought into contact with each other.

[0016] The device body may have an operation panel at one end in a second direction perpendicular to the first direction, and the holding part may be located between the other end of the device body in the second direction and the inner surface of the outer box.

[0017] Since the consumables can be placed on the opposite side of the operation panel, the consumables can be placed in a location on the device body that does not have a complex shape, and the package can be made compact without increasing the size of the entire package.

[0018] The consumable may be a developing cartridge having a developing roller rotatable about a rotation axis and a toner containing portion that contains toner. The developing cartridge may be held by the holding portion with the rotation axis extending in the first direction.

[0019] Since the developing cartridge is held in the holding portion with the rotation axis of the developing roller extending in the first direction, even if the packaging body falls downward, the developing cartridge can be prevented from receiving an impact from the first direction.

[0020] The consumable item may be a drum unit having a photosensitive drum rotatable around a rotation shaft. The drum unit may be held by a holder with the rotation shaft extending in the first direction.

[0021] Since the drum unit is held in the holding portion with the rotation axis of the photosensitive drum extending in the first direction, even if the package falls downward, the drum unit can be prevented from receiving an impact from the first direction.

[0022] The drum unit may be equipped with a developer cartridge having a developer roller rotatable about a rotation axis and a toner storage section that stores toner. In addition to the drum unit, one more developer cartridge may be held between the center pad and the bottom pad.

[0023] The package may be a cardboard box having a pair of flaps closing the top surface, and the slits between the pair of flaps may extend in a second direction perpendicular to the first direction.

[0024] In order to solve the problem, the pulp molded cushioning material according to the present disclosure is disposed between the main body of the printing device and an outer box that houses the main body, and protects the main body. The pulp molded cushioning material includes a first pad and a second pad. The first pad has a first protruding portion protruding downward. The second pad has a second protruding portion protruding upward. The second pad is disposed below the first pad. A tip portion of the first protruding portion has a first uneven surface. A tip portion of the second protruding portion has a second uneven surface. The first uneven surface and the second uneven surface engage with each other.

[0025] The device body can be protected by the first and second pads that are arranged vertically. The part where the first and second pads engage has an uneven surface. This ensures the rigidity of the part where the first and second pads engage, allowing the cushioning effect to be fully exerted at the part where the two pads engage, and the device body can be adequately protected by the pulp mold cushioning material.

[0026] Moreover, both the first uneven surface and the second uneven surface may have a stepped shape.

[0027] Since both the first uneven surface and the second uneven surface have a stepped shape, they can be easily brought into contact with each other. Effect of the Invention

[0028] According to the present disclosure, the device body and consumables can be adequately protected without increasing the size of the packaging body provided with pulp molded cushioning material. According to the present disclosure, the device body can be adequately protected with a cushioning material made of molded pulp. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Next, an embodiment of the present disclosure will be described in detail with reference to the drawings as appropriate. In the following description, the direction along the rotation axis X1 of the photosensitive drum 2A shown in FIG. 3 is referred to as the "first direction." Additionally, the up-down direction and the direction perpendicular to the first direction are referred to as the "second direction." Additionally, the arrows indicating each direction in the drawings indicate "one side" in each direction. The direction opposite to the "one side" is referred to as the "other side." In the following description, one side of the first direction may be referred to as the "front," the other side of the first direction as the "rear," one side of the second direction as the "left," and the other side of the second direction as the "right."

[0031] As shown in FIG. 1, the package PA is for protecting the printing device 1 and the drum unit 2 from impact during transportation. The printing device 1 is a device that forms an image on a sheet with the drum unit 2 attached. The printing device 1 is, for example, a printer, a copier, or a multifunction device. The package PA houses the device body 1A of the printing device 1 and the drum unit 2. The drum unit 2 is an example of a consumable item that can be attached to and detached from the device body 1A. The package PA includes an outer box 5, a top pad TP as an example of a first pad, a bottom pad BP, and a center pad 90 as an example of a second pad. In the following description, the state in which the device body 1A to which the top pad TP, the bottom pad BP, and the center pad 90 are attached is housed in the outer box 5 is referred to as a "packaged state."

[0032] As shown in Fig. 2, the device main body 1A has a front cover 1B and an operation panel 1C. The front cover 1B can be moved between an open position and a closed position. When the front cover 1B is in the open position, the drum unit 2 is detachable from the device main body 1A. The operation panel 1C can be used to input operations for forming an image. The front cover 1B and the operation panel 1C are disposed at one end of the device main body 1A in the second direction, i.e., on the front side of the device main body 1A.

[0033] The drum unit 2 has a photosensitive drum 2A, a mounting portion 2B, a handle 2H, and a drum memory 2M. The photosensitive drum 2A is rotatable about a rotation axis X1 extending in a first direction. The developing cartridge 3 can be mounted in the mounting portion 2B. The mounting portion 2B is located between the photosensitive drum 2A and the handle 2H. The handle 2H is held by a user when attaching or detaching the drum unit 2. The drum memory 2M is a storage medium such as an IC chip, and stores information about the drum unit 2. The drum memory 2M is disposed on the outer wall of the drum unit 2 and is exposed to the outside.

[0034] The developing cartridge 3 includes a developing roller 3 A and a toner storage section 3 B. The developing roller 3 A supplies toner to the photosensitive drum 2 A. The toner storage section 3 B stores toner therein.

[0035] In this embodiment, the drum unit 2 is packaged in a package PA separately from the apparatus main body 1A. When the printing apparatus 1 is used, the drum unit is attached to the apparatus main body 1A.

[0036] 1, the outer box 5 is made of, for example, cardboard. The outer box 5 accommodates the device main body 1A and the drum unit 2 inside with the top pad TP, bottom pad BP, and center pad 90 attached to the device main body 1A. The outer box 5 is a hollow rectangular parallelepiped.

[0037] The bottom pad BP is disposed between the lower part of the device body 1A and the outer box 5. The bottom pad BP covers a part of the lower part of the device body 1A. The bottom pad BP prevents external impacts applied to the package PA during transportation from being transmitted to the lower part of the device body 1A. The bottom pad BP is a cushioning material made of pulp mold. Pulp mold is a molded product made from pulp, the raw material for paper, recycled paper, and other materials. Pulp mold is easy to reuse and has better environmental performance than polystyrene foam and the like.

[0038] As shown in FIG. 3, in this embodiment, the bottom pad BP includes a first bottom pad 10, a second bottom pad 20, a third bottom pad 30, and a fourth bottom pad 40.

[0039] 4(b), the first bottom pad 10 covers the left front corner of the device main body 1A from below. The first bottom pad 10 has a lower buffer section 11, a left buffer section 12, a front buffer section 13, a second left buffer section 14, and a main body receiving section 18.

[0040] The lower buffer section 11 is located below the device body 1A in the packaged state and is in contact with the device body 1A. The lower buffer section 11 prevents an impact from below from being transmitted to the left front part of the device body 1A.

[0041] The left-side buffer section 12 extends upward from the left end of the lower-side buffer section 11. The left-side buffer section 12 is located on the left of the device main body 1A in the packaged state, and is in contact with the device main body 1A. The left-side buffer section 12 prevents an impact from the left from being transmitted to the left front section of the device main body 1A.

[0042] The left-side buffer part 12 has a first inclined surface 12A and a first protrusion 12B. The first inclined surface 12A is provided at the front end of the left-side buffer part 12. The first inclined surface 12A is an inclined surface that slopes downward toward the front. The first protrusion 12B is a protrusion that protrudes upward from the first inclined surface 12A. The first protrusion 12B has the shape of a right-angled isosceles triangle.

[0043] The front buffer section 13 is located in front of the device body 1A in the packaged state and contacts the device body 1A. The front buffer section 13 prevents a shock from the front from being transmitted to the left front section of the device body 1A.

[0044] The second left-side buffer section 14 extends rearward from the left end of the front-side buffer section 13. The second left-side buffer section 14 is located on the left of the device main body 1A in the packaged state and contacts the device main body 1A.

[0046] Here, the first bottom pad 10 is folded from a first state shown in Fig. 4(a) to a second state shown in Fig. 4(b) and used as a part of the package PA. As shown in Fig. 4(a), the first bottom pad 10 has a first portion P1 including a lower buffer portion 11 and a left buffer portion 12, and a second portion P2 including a front buffer portion 13 and a second left buffer portion 14. The first portion P1 and the second portion P2 are integrally formed in a connected state. The second portion P2 can be folded relative to the first portion P1, with the connecting portion P3 as a fold line.

[0047] As shown in FIG. 4(b), when the first bottom pad 10 is bent from the first state to the second state, the first inclined surface 12A of the left buffer section 12 and the second inclined surface 14A of the second left buffer section 14 come into contact with each other, and the first protrusion 12B enters the engagement hole 14B. As the first protrusion 12B engages with the engagement hole 14B, the first bottom pad 10 maintains the second state without returning to the first state. As the first inclined surface 12A and the second inclined surface 14A come into contact with each other, the contacting portions become two-ply, which greatly suppresses the transmission of an impact from the left to the left front portion of the device main body 1A.

[0048] The main body receiving section 18 is a section that receives the left front corner of the device main body 1A. The main body receiving section 18 is a space surrounded by the lower buffer section 11, the left buffer section 12, the front buffer section 13, and the second left buffer section 14.

[0065] The main body receiving section 38 is a section that receives the left rear corner of the device main body 1A. The main body receiving section 38 is a space surrounded by the lower buffer section 31, the left buffer section 32, the first protrusion section 35, and the second protrusion section 36.

[0066] The preliminary receiving portion 39 is a portion that receives, for example, a part of a consumable such as the developing cartridge 3. The preliminary receiving portion 39 is a space surrounded by the rear buffer portion 33, the first protrusion portion 35, and the second protrusion portion .

[0067] Here, the third bottom pad 30 is folded from a first state shown in Fig. 6(a) to a second state shown in Fig. 6(b) and used as a part of the package PA.

More specifically, the second protrusion 94 is provided in two locations: between the holding portion 91 and the second holding portion 92, and between the holding portion 91 and the third holding portion 93. More specifically, one of the second protrusions 94 is formed by the left end of the holding portion 91 and the right end of the second holding portion 92, and the other is formed by the right end of the holding portion 91 and the left end of the third holding portion 93.

[0113] In the second direction, the dimension D1 of the second protruding portion 94 is larger than the dimension D2 of the first protruding portion 72 of the third top pad 70. In addition, in the second direction, the dimension D1 of the second protruding portion 94 is larger than the dimension D3 of the first protruding portion 82 of the fourth top pad 80.

[0114] In the packaged state, the tip of the second protrusion 94 has a contact portion 94A that contacts the first protrusions 72, 82 of the top pad TP. The two contact portions 94A are disposed on both sides of the holding portion 91 in the first direction. One contact portion 94A contacts the tip portion 72A of the first protrusion 72 of the third top pad 70. The other contact portion 94A contacts the tip portion 82A of the first protrusion 82 of the fourth top pad 80. The two contact portions 94A each overlap the holding portion 91 when viewed from the first direction.

[0115] The contact portion 94A is located in the first direction between the holding portion 91 and the inner surface of the outer box 5. The contact portion 94A is located at a position closer to the inner surface of the outer box 5 than the center C of the outer box 5 in the first direction.

[0116] 8(a) and (b), the contact portion 94A has a second uneven surface 94S. The second uneven surface 94S has a stepped shape that is positioned lower as it moves away from the holding portion 91 in the first direction. In the packaged state, the second uneven surface 94S and the first uneven surfaces 72S, 82S of the first protrusions 72, 82 engage with each other.

[0117] 11, the outer box 5 has a pair of inner flaps 5A and a pair of flaps 5B at the top. The top surface of the outer box 5 is closed by closing the pair of inner flaps 5A and then overlapping the pair of flaps 5B on the pair of inner flaps 5A. The slits BR of the pair of flaps 5B extend in the second direction.

[0118] As described above, the following effects can be obtained in this embodiment. If the printing device 1 is transported with the drum unit 2 attached to the device main body 1A, it is more susceptible to damage than if they are packed separately, so it is preferable to pack the device main body 1A and the drum unit 2 separately when transporting the printing device 1. For example, it is possible that the drum unit 2 may move inside the device main body 1A and be damaged, or that the drum memory 2M of the drum unit 2 may rub against the reading contact (not shown) of the device main body 1A and become worn. However, according to the packaging body PA of the present embodiment, the packaging body PA includes a top pad TP arranged on the upper part of the device main body 1A, a bottom pad BP arranged on the lower part of the device main body 1A, and a center pad 90 that holds the drum unit 2. The center pad 90 is arranged in contact with the top pad TP and the bottom pad BP, so that the entire packaging body PA can ensure cushioning, especially in the vertical direction. As a result, cushioning can be ensured compared to a configuration in which the center pad 90 is separated from the top pad TP or the bottom pad BP, or a configuration in which the center pad 90 is not provided, so that the top pad TP and the bottom pad BP can be made smaller. As a result, both the device main body 1A and the drum unit 2 of the printing device 1 can be protected without increasing the size of the packaging body PA. In addition, since the drum unit 2 is held by the center pad 90, the drum unit 2 can be positioned near the center in the vertical direction, so that the drum unit 2 can be appropriately protected. And, since the top pad TP, the bottom pad BP, and the center pad 90 are made of pulp molded cushioning material, environmental performance can be improved.

[0119] In addition, since the contact portion 94A of the center pad 90 where the top pad TP comes into contact is located outside the holding portion 91, the contact portion 94A can protect the drum unit 2 from the outside.

[0120] Furthermore, since the tip portions 72A, 82A of the first protrusions 72, 82 of the top pad TP have the first uneven surfaces 72S, 82S, the rigidity of the tip portions 72A, 82A can be increased. Furthermore, since the contact portion 94A of the center pad 90 has the second uneven surface 94S, the rigidity of the contact portion 94A can be increased. This makes it difficult for the tip portions 72A, 82A to be easily crushed, and the drum unit 2 can be appropriately protected.

[0121] In addition, the first uneven surfaces 72S, 82S of the first protrusions 72, 82 of the top pad TP and the second uneven surface 94S of the contact portion 94A of the center pad 90 both have a stepped shape, and therefore can easily be brought into contact with each other.

[0122] In addition, since the drum unit 2 can be disposed on the opposite side of the operation panel 1C, the drum unit 2 can be disposed in a location on the device body 1A where the shape is not complicated in the packaged state. This allows the package PA to be made compact without increasing its overall size.

[0123] In addition, since the drum unit 2 is held in the holding portion with the rotation axis X1 of the photosensitive drum 2A extending in the first direction, even if the package PA falls downward, the drum unit 2 can be prevented from receiving an impact from the direction in which the rotation axis X1 extends. 9, one side of the drum unit 2 in the first direction is protected by two protrusions, the first protrusion 72 of the third top pad 70 and the second protrusion 94 of the center pad 90, so that even if the outer box 5 receives an external force from the first direction, an impact is unlikely to be transmitted to the drum unit 2. Similarly, the other side of the drum unit 2 in the first direction is protected by two protrusions, the first protrusion 82 of the fourth top pad 80 and the second protrusion 94 of the center pad 90, so that even if the outer box 5 receives an external force from the first direction, an impact is unlikely to be transmitted to the drum unit 2.

[0124] The present disclosure is not limited to the above-described embodiment, but can be used in various forms as exemplified below.

[0125] In the embodiment described above, the package PA contains the main body 1A of the printing device 1 and the drum unit 2, but it may also contain other consumables.

[0126] 12(a) and (b), for example, the package PA holds one developer cartridge 3 in addition to the drum unit 2. This package PA holds the developer cartridge 3 between the center pad 90 and the bottom pad BP.

[0127] In the packaged state, the sixth protruding portion 91B of the center pad 90 is positioned above the developer cartridge 3, and prevents the developer cartridge 3 from receiving an impact from above. In the packaged state, the third convex portion 37 of the third bottom pad 30 and the third convex portion 47 of the fourth bottom pad 40 are located below the developing cartridge 3, preventing impact from being transmitted from below to the developing cartridge 3. In the packaged state, the first convex portion 35 of the third bottom pad 30 and the first convex portion 45 of the fourth bottom pad 40 are located in front of the developing cartridge 3, preventing an impact from being transmitted to the developing cartridge 3 from the front. In the packaged state, the boss 33A and the boss 44A of the third bottom pad 30 are located behind the developing cartridge 3, and prevent the developing cartridge 3 from receiving an impact from behind. In the packaged state, the second protrusion 36 of the third bottom pad 30 is located to the left of the developing cartridge 3, and prevents an impact from being transmitted to the developing cartridge 3 from the left. In the packaged state, the second convex portion 46 of the fourth bottom pad 40 is located to the right of the developer cartridge 3, and prevents an impact from being transmitted to the developer cartridge 3 from the right. In addition, since the developing cartridge 3 is held in the holding portion 92 with the rotational axis of the developing roller 3A extending in the first direction, even if the packaging body PA falls downward, the developing cartridge 3 can be prevented from receiving an impact from the direction in which the rotational axis of the developing roller 3A extends.

[0128] In the above embodiment, the drum unit 2 is illustrated as an example of a consumable item, but the consumable item may be a developing cartridge or a toner cartridge. Also, the consumable item may be a process unit in which the drum unit 2 and the developing cartridge are integrated.

[0129] In the above-described embodiment, for example, in a pad such as the first bottom pad 10 that is folded from a first state to a second state and used as part of the packaging body PA, the first and second inclined portions have flat shapes, but this is not limited to this form. For example, the first inclined surface 112A of the first bottom pad 110 shown in Figures 13(a) and (b) has an uneven surface. Also, the second inclined surface 114A of the first bottom pad 110 has an uneven surface. When the first bottom pad 110 is folded from the first state shown in Figure 13(a) to the second state shown in Figure 13(b), the uneven surface of the first inclined surface 112A and the uneven surface of the second inclined surface 114A come into contact with each other and engage with each other. In this embodiment, the first inclined surface 112A and the second inclined surface 114A have uneven surfaces, which increases the rigidity of the first inclined surface 112A and the second inclined surface 114A. Therefore, the first inclined surface 112A and the second inclined surface 114A are not easily crushed, and the apparatus body 1A can be appropriately protected.

[0130] In the above-described embodiment, the first uneven surface 72S and the second uneven surface 94S have a step shape that becomes lower as it moves away from the holding portion 91 in the first direction, but the present invention is not limited to this configuration. For example, as shown in FIG. 14(a), a first uneven surface 172S and a second uneven surface 194S may have a stepped shape that rises with increasing distance from the holding portion 91 in the first direction. For example, as shown in FIG. 14(b), a first uneven surface 272S may have a groove shape with a rectangular cross section, and a second uneven surface 294S may have a bead shape corresponding to the groove. For example, as shown in FIG. 14(c), a first uneven surface 372S may have a plurality of groove shapes with a V-shaped cross section, and a second uneven surface 394S may have a plurality of bead shapes corresponding to the first uneven surface 372S. According to the configurations of FIGS. 14(a), (b) and (c), the first uneven surface and the second uneven surface have a plurality of corners, so that the rigidity is increased and the surface is not easily crushed.

[0131] In the above-described embodiment, the top pad TP and the bottom pad BP are each composed of four pads, but may be composed of one to three pads, or may be composed of five or more pads.

[0132] In the above-described embodiment, the outer box 5 is made of cardboard, but the outer box may be a box made of a material other than cardboard, such as resin, wood, or metal.

[0133] In the above-described embodiment, the device body, consumables and cushioning materials are packed without being wrapped in a sheet or bag, but the device body, consumables and cushioning materials may also be packed wrapped in a vinyl sheet, vinyl bag, aluminum sheet, aluminum bag, etc.

[0134] The toner cartridge does not have to have a developing roller. For example, the toner cartridge may be a cartridge that is detachable from a developing cartridge that has a developing roller.

[0135] The elements described in the above-mentioned embodiment and modified examples may be implemented in any combination. [Explanation of symbols]
