Description

[Technical Field]

[0001] The present disclosure relates to a shipping container. [Background technology]

[0002] Patent Document 1 describes a top plate member for covering the top opening of a container, which includes a strip-shaped flap and a hinge leg protruding from one end of the flap in the width direction. The hinge leg is provided with a shaft protrusion that is rotatably connected to the upper end of the side wall of the container.

[0003] In this container, the flap (i.e., the lid) can be rotated between an inward-leaning position (i.e., a covering position) in which it is substantially horizontal and covers the top opening of the container, and a hanging position (i.e., an open position) in which it is superimposed on the outer surface of the side wall of the container. By putting the flap in the hanging position, the amount of protrusion of the flap outside the container can be reduced. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 6411237 Summary of the Invention [Problem to be solved by the invention]

[0005] In the container described in Patent Document 1, the positions of the axial protrusion and the flap in the thickness direction of the flap are shifted so that the flap, which rotates around the axial protrusion, can rotate to a hanging position.

[0006] Therefore, when the flap is in a substantially horizontal, inwardly tilted position, the flap is positioned lower than the axial protrusion, which causes the storage space below the flap inside the container to become narrower in the vertical direction.

[0007] In view of the above circumstances, the present disclosure aims to provide a transport container that makes it easy to ensure a wide storage space in the vertical direction below the lid when in the covered position, and that makes it easy to reduce the amount of protrusion of the lid outside the container when in the open position. [Means for solving the problem]

[0008] A transport container according to one aspect of the present disclosure includes a box-shaped container body having an opening on its top surface, and a lid connected to the container body so as to move between a covering position that covers the opening and an opening position that opens the opening along the outer surface of the container body. The lid has a plate-shaped lid body that covers or opens the opening, and a connecting portion that protrudes from one end of the lid body and is rotatably connected to the upper end of the container body. The lid is rotatable around a central axis located at the connecting portion. The lid body includes a first portion located on the connecting portion side and a second portion located on the opposite side from the connecting portion. When the lid is in the covering position, the first portion is located below the central axis, and the lower surface of the second portion is located above the lower surface of the first portion. [Effects of the Invention]

[0009] In one embodiment of the transport container according to the present disclosure, it is easy to ensure a wide storage space in the vertical direction below the lid in the covered position, and it is also easy to reduce the amount of protrusion of the lid outside the container when in the open position.

[0011] (One embodiment) 1. Overview 1 and 2A , a transport container 1 according to one embodiment includes a box-shaped container body 2 having an opening 20 on its top surface, and a lid 3 connected to the container body 2 so as to move between a covering position where the opening 20 is covered and an open position where the opening 20 is opened along the outer surface of the container body 2. The lid 3 includes a plate-shaped lid body 30 that covers or opens the opening 20, and a connecting portion 31 that protrudes from one end of the lid body 30 and is rotatably connected to the upper end of the container body 2. The lid 3 is rotatable around a central axis L1 located at the connecting portion 31. The lid body 30 includes a first portion 30a located on the connecting portion 31 side and a second portion 30b located on the opposite side from the connecting portion 31. When the lid 3 is in the covering position, the first portion 30a is located below the central axis L1, and the lower surface of the second portion 30b is located above the lower surface of the first portion 30a.

[0012] In one embodiment of the transport container 1 having the above configuration, when the lid 3 is in the covering position covering the opening 20 of the container body 2, the underside of the second portion 30b of the lid body 30 is located higher than the underside of the first portion 30a. Therefore, in one embodiment of the transport container 1, the storage space formed below the lid body 30 can be made larger in the vertical direction compared to when the lid body 30 is entirely made up of the first portion 30a. Furthermore, in one embodiment of the transport container 1, when the lid 3 is rotated and positioned along the outer surface of the container body 2, the second portion 30b is located closer to the container body 2 than the first portion 30a, making it easier to reduce the amount of protrusion of the lid 3 outside the container when in the open position.

[0013] 2.Details Next, the transport container 1 of this embodiment shown in Figures 1 to 4 will be described in more detail with reference to the drawings. The transport container 1 includes a box-shaped container body 2 having an opening 20 on its top surface, and a lid 3 connected to the container body 2 so as to move between a covering position (see Figure 1) that covers the opening 20 and an opening position (see Figure 3) that opens the opening 20 along the outer surface of the container body 2.

[0014] 2-1. Container body As shown in Fig. 3, the container body 2 is box-shaped with an opening 20 on the top surface. The container body 2 is a roughly rectangular box-shaped. In the following, each configuration will be described with the longitudinal direction of the container body 2 in a plan view as the front-rear direction, the lateral direction of the container body 2 in a plan view as the left-right direction, and the direction perpendicular to the left-right direction and the front-rear direction as the up-down direction.

[0015] The container body 2 includes a bottom wall 21 that is rectangular in plan view, a pair of first side walls 22 rotatably connected to a pair of long side edges (i.e., left and right edges) of the bottom wall 21, and a pair of second side walls 23 rotatably connected to a pair of short side edges (i.e., front and rear edges) of the bottom wall 21. Each of the pair of first side walls 22 and the pair of second side walls 23 is plate-shaped.

[0016] The container body 2 can be changed between an assembled state in which a pair of first side walls 22 and a pair of second side walls 23 are in an upright position and stand up on the outer periphery of the bottom wall 21, and a folded state (not shown) in which a pair of second side walls 23 and a pair of first side walls 22 are in a laid-down position and stacked in this order on top of the bottom wall 21.

[0017] 2-1-1. Bottom wall The bottom wall 21 is composed of a bottom wall main body 210 that is rectangular in plan view, a pair of first connecting walls 211 that protrude upward from the left and right ends of the bottom wall main body 210, and a pair of second connecting walls 212 that protrude upward from the front and rear ends of the bottom wall main body 210.

[0018] As shown in FIG. 4A, bottom wall main body 210 is composed of top plate portion 2100 in the form of a rectangular flat plate in a plan view, and lattice-like ribs 2101 protruding from the lower surface of top plate portion 2100.

[0019] 3, the pair of first connecting walls 211 protrude upward more than the pair of second connecting walls 212. A connecting portion 2110 to which the first side wall 22 is rotatably connected is provided at the upper portion of each of the pair of first connecting walls 211. A connecting portion 2120 to which the second side wall 23 is rotatably connected is provided at the upper portion of each of the pair of second connecting walls 212. The connecting portion 2110 is located higher than the connecting portion 2120. In this embodiment, each of the connecting portions 2110, 2120 is a recessed portion that opens upward and toward the inside of the container body 2.

[0020] 2-1-2.First side wall Each of the pair of first side walls 22 has a connecting portion 220 at its lower end that is rotatably connected to the connecting portion 2110, and a lid connecting portion 221 at its upper end that is rotatably connected to the lid 3.

[0021] As shown in Fig. 1, the lid connecting portion 221 is composed of a plurality of rotating shafts 221a and a plurality of bearings 221b. The plurality of rotating shafts 221a and the plurality of bearings 221b are arranged at intervals in the front-rear direction so that the rotating shafts 221a and the bearings 221b are arranged alternately one by one. Each of the plurality of rotating shafts 221a is composed of a rod-shaped shaft body 2210 and a pair of block-shaped support portions 2211 that support both ends of the shaft body 2210 in the longitudinal direction. Each of the plurality of bearings 221b is block-shaped and open outward in the left-right direction.

[0022] Each of the pair of first side walls 22 has a side wall main body 222 that is rectangular and flat when viewed from the side, a lattice-shaped rib 223 protruding from the upper end of the outer surface (the surface facing outward in the left-right direction) of the side wall main body 222, and a plurality of ribs 224 protruding from the remaining part of the outer surface of the side wall main body 222.

[0023] The lattice-shaped rib 223 is made up of multiple horizontal ribs 223a extending in the front-to-rear direction and multiple vertical ribs 223b extending in the up-down direction. A pair of support portions 2211 and each bearing portion 221b of each rotation shaft 221a of the lid connecting portion 221 protrude upward from the uppermost horizontal rib 223a among the multiple horizontal ribs 223a.

[0024] Each of the plurality of ribs 224 is a vertical rib that extends linearly in the up-down direction. Each of the pair of first side walls 22 further has a recess 225 formed between two of the plurality of ribs 224 that are adjacent in the front-to-rear direction. Each of the pair of first side walls 22 has a plurality of recesses 225 that are lined up at intervals in the front-to-rear direction.

[0025] Each of the pair of first side walls 22 further has, at both ends in the front-rear direction, an engagement portion 226 for engaging with the second side wall 23 in the upright position.

[0026] 2-1-3.Second side wall As shown in FIG. 3, each of the pair of second side walls 23 is provided at its lower end with a connecting portion 230 that is rotatably connected to the connecting portion 2120.

[0027] An opening 231 for a handle is provided in the center in the left-right and up-down directions of each of the pair of second side walls 23. The opening 231 penetrates the second side wall 23 in the thickness direction (i.e., the front-rear direction).

[0028] Each of the pair of second side walls 23 is provided at both ends in the left-right direction with an engagement portion 232 for engagement with the engagement portion 226 of the first side wall 22 in the upright position.

[0029] A recess 233 is provided above the opening 231 of each of the pair of second side walls 23. The recess 233 has a locking member 4 disposed therein that locks the side walls 22, 23 in an engaged state. The recess 233 opens outward in the front-rear direction and does not penetrate the second side wall 23.

[0030] The upper end of each of the pair of second side walls 23 is further provided with a locking hole 234 into which a lid locking member 5 for locking the lid 3 to the second side wall 23 can be inserted, and a locking recess 235 for hooking the lid 3. The locking hole 234 opens at least on the inside in the front-to-rear direction. In this embodiment, the locking hole 234 penetrates the second side wall 23 in the thickness direction (i.e., the front-to-rear direction) and opens on both the inside and outside in the front-to-rear direction. The locking recess 235 opens on the inside in the front-to-rear direction and upward.

[0031] 2-1-4. Locking member The locking member 4 is a member for locking the state in which the engaging portions 226, 232 of the side walls 22, 23 are engaged with each other when the locking member 4 is in the upright position. The locking member 4 has a main body 40 that can be operated by the user, and a biasing portion 41 that biases the main body 40 upward. The biasing portion 41 is composed of two pairs of leaf springs 410 that protrude from the underside of the main body 40. Each pair of leaf springs 410 is arranged in a V-shape.

[0032] When not operated by the user (when no load is applied), the locking member 4 is biased upward by the biasing portion 41 and is located in the locking position above the recess 233. When in the locked position, the locking member 4 locks the engaging portions 226, 232 of the side walls 22, 23, which are in an engaged state. The user can release the locked state by the locking member 4 by lowering the main body 40. In this state, by rotating the second side wall 23, which is in the upright position, inward in the front-to-rear direction, the engaging portions 226, 232 of the side walls 22, 23 can be released from the engaged state, and the second side wall 23, which is in the upright position, can be moved to the laid-down position.

[0033] 2-2. Lid Each of the pair of lids 3 shown in Figures 1 and 3 is connected to the container body 2 so as to move between a covering position (see Figure 1) where it covers the opening 20 of the container body 2 and an opening position (see Figure 3) where it opens the opening 20 along the outer surface of the container body 2. The pair of lids 3, 3 have a common structure. Each configuration of the lid 3 will be described based on the state in which it is in the covering position shown in Figure 1.

[0034] The pair of lids 3 are rotatably connected to lid connecting portions 221 at the upper ends of the pair of first side walls 22. In this embodiment, the left-right length of the lids 3 is approximately one-third to one-fourth of the left-right length of the second side wall 23. When the pair of lids 3, 3 are arranged in the covering position, a gap is formed between the pair of lids 3, 3 that connects to the storage space inside the container body 2.

[0035] The lid 3 has a plate-shaped lid body 30 that covers or opens the opening 20 of the container body 2, and a connecting part 31 that protrudes from one end of the lid body 30 and is rotatably connected to the upper end of the container body 2. The lid 3 is rotatable around a central axis L1 (see FIG. 2A) located on the connecting part 31. In this embodiment, the lid 3 further includes a lid locking member 5 that is attached to the lid body 30. In FIGS. 6 to 8, the lid 3 is shown alone.

[0036] 2-2-1. Lid body 8, the lid body 30 has a top plate 300, a peripheral rib 301 that protrudes downward from the outer peripheral edge of the top plate 300, and a lattice-shaped inner rib 302 that protrudes downward from a portion more inward than the outer peripheral edge of the top plate 300. The lid body 30 further has a groove-forming rib 303 that protrudes downward from a portion more inward than the outer peripheral edge of the top plate 300 and opens upward.

[0037] The outer peripheral rib 301 and the inner rib 302 are each plate-shaped. The groove-forming rib 303 is semi-cylindrical, and is longer in the width direction perpendicular to the length direction than the outer peripheral rib 301 and the inner rib 302, and has a shorter protruding length (length in the vertical direction). Therefore, the lower surface of the groove-forming rib 303 is located higher than the lower surfaces of the outer peripheral rib 301 and the inner rib 302. The upper surface of the top plate 300 forms the upper surface of the lid main body 30, and the lower surfaces of the outer peripheral rib 301 and the inner rib 302 form the lower surface of the lid main body 30.

[0038] The inner rib 302 is composed of a plurality of first ribs 302a extending in the front-rear direction and spaced apart in the left-right direction, and a plurality of second ribs 302b extending in the left-right direction and spaced apart in the front-rear direction. The plurality of first ribs 302a are provided at the end of the tabletop 300 opposite the connecting portion 31. Each of the plurality of first ribs 302a is provided from the front end to the rear end of the tabletop 300, and the front and rear ends are integrally continuous with the outer peripheral rib 301. The protruding length of each of the plurality of first ribs 302a from the tabletop 300 is constant over the entire length in the front-rear direction. Each of the plurality of first ribs 302a is strip-shaped.

[0039] Each of the second ribs 302b is provided from the left end to the right end of the table top 300, and both the left end and the right end are continuous with the outer peripheral rib 301. Each of the second ribs 302b has an end on the connecting portion 31 side and an end on the opposite side from the connecting portion 31 that are located at different positions in the thickness direction of the table top 300 (the vertical direction in the drawing).

[0040] Each of the multiple second ribs 302b has a band-shaped portion 3020 located at the end on the connecting portion 31 side, and a band-shaped portion 3021 located at the end opposite the connecting portion 31 and higher than portion 3020. Each of the multiple second ribs 302b further includes a band-shaped portion 3022 located between portions 3020, 3021 and inclined relative to portions 3020, 3021. The lower surface of portion 3021 is flush with the lower surfaces of the multiple first ribs 302a.

[0041] The groove forming ribs 303 are positioned at intervals in the front-rear direction. The groove forming ribs 303 are positioned offset in the front-rear direction with respect to the second ribs 302b. The end of each of the groove forming ribs 303 opposite the connecting portion 31 is integrally continuous with the outer peripheral rib 301.

[0042] The groove forming rib 303 has a pair of side plate portions 304 positioned apart in the width direction (front-to-back direction in this embodiment) of the groove forming rib 303, and a bottom plate portion 305 connecting the lower ends of the pair of side plate portions 304.

[0043] As shown in Figure 6, the top plate 300 has a plurality of elongated holes 306 formed at positions corresponding to the plurality of groove-forming ribs 303. Each of the plurality of elongated holes 306 extends in the left-right direction and penetrates the top plate 300 in the thickness direction (i.e., the up-down direction). The plurality of elongated holes 306 are positioned at intervals in the front-rear direction. A pair of side plate portions 304 protrudes downward from both edges of each of the plurality of elongated holes 306 in the width direction.

[0044] The space surrounded by the pair of side plate portions 304 and bottom plate portion 305 (i.e., the internal space of groove-forming rib 303) and the long hole 306 communicating with the upper part thereof constitute groove 35. Groove 35 does not penetrate lid main body 30 in the thickness direction thereof.

[0045] A plurality of grooves 35 are formed in the lid body 30. Each of the grooves 35 extends in the left-right direction and is open upward and on both the left and right sides. The arrangement of the grooves 35 in the lid body 30 is the same as the arrangement of the ribs 224 provided on the outer surface of the first side wall 22.

[0046] The formation of the multiple grooves 35 in the lid body 30 makes the lid body 30 more easily deformable. Therefore, when the contents contained in the transport container 1 come into contact with the bottom surface of the lid body 30 of the lid 3 in the covering position, the load is less likely to be applied from the lid body 30 to the contents compared to when the multiple grooves 35 are not provided in the lid body 30.

[0047] As shown in FIG. 6, the lid body 30 includes a first portion 30a located on the connecting portion 31 side and a second portion 30b located on the opposite side to the connecting portion 31.

[0048] The first portion 30a is the end of the lid body 30 on the connecting portion 31 side, and is a portion that extends linearly in the left-right direction. The entire remaining portion of the lid body 30 excluding the first portion 30a is the second portion 30b.

[0049] The second portion 30b is continuous with the first portion 30a and includes an inclined portion 30c that is inclined upward as it moves away from the first portion 30a, and a main portion 30d that extends linearly in the left-right direction. The inclined portion 30c is the end of the second portion 30b that faces the first portion 30a, and the main portion 30d is the entire remaining portion excluding the inclined portion 30c. The center of the thickness direction of the main portion 30d and the central axis L1 of the connecting portion 31 are located at approximately the same height (in other words, they are located at approximately the same position in the thickness direction of the lid main body 30). The main portion 30d occupies more than half of the width of the lid main body 30.

[0050] The upper surface of the first portion 30a is made up of the upper surface of the top plate 300 in the first portion 30a, and the lower surface of the first portion 30a is made up of the lower surface of the outer circumferential rib 301 and the lower surfaces of the plurality of second ribs 302b in the first portion 30a. The upper surface of the second portion 30b is made up of the upper surface of the top plate 300 in the second portion 30b, and the lower surface of the second portion 30b is made up of the lower surface of the outer circumferential rib 301, the lower surfaces of the plurality of first ribs 302a, and the lower surfaces of the plurality of second ribs 302b in the second portion 30b.

[0051] As shown in Figure 6, the lid body 30 further has a locking protrusion 36 that hooks into the locking recess 235 of the second side wall 23 when the lid 3 is in the covering position, and a recess 37 that accommodates the lid lock member 5 that locks the lid 3 in the covering position to the second side wall 23.

[0052] The locking protrusions 36 protrude outward in the front-to-rear direction from each of the front and rear ends of the lid body 30. The locking protrusions 36 are provided on the end of the lid body 30 opposite the connecting portion 31. The locking protrusions 36 are shaped so that they can be hooked onto the locking recesses 235 of the second side wall 23. In this embodiment, the cross section of the locking protrusions 36 perpendicular to the front-to-rear direction is U-shaped.

[0053] Recesses 37 are provided at both the front and rear ends of the top panel 300. The recess 37 is entirely open upward and partially open downward. The lid locking member 5 is housed in the recess 37 so that it can slide in the front-rear direction. An insertion hole 3010 is provided in the portion of the outer circumferential rib 301 that is located outside the recess 37 in the front-rear direction, through which a part of the lid locking member 5 (the locking claw 51 described in detail later) is inserted. The insertion hole 3010 is a notched hole that penetrates the outer circumferential rib 301 in the front-rear direction and opens downward.

[0054] 2-2-2.Connection part The connecting portion 31 has a structure that allows it to be rotatably connected to the lid connecting portion 221 at the upper end of the first side wall 22. In this embodiment, the connecting portion 31 has a similar structure to the lid connecting portion 221.

[0055] The connecting portion 31 is composed of a plurality of rotating shafts 31a and a plurality of bearings 31b. The plurality of rotating shafts 31a and the plurality of bearings 31b are arranged at intervals in the front-rear direction so that the rotating shafts 31a and the bearings 31b are arranged alternately one by one. Each of the plurality of rotating shafts 31a is composed of a rod-shaped shaft body 310 and a pair of block-shaped support portions 311 that support both ends of the shaft body 310 in the longitudinal direction. Each of the plurality of bearings 31b is block-shaped and open upward.

[0056] The multiple rotation shafts 31a of the lid 3 are rotatably supported by the multiple bearings 221b of the first side wall 22, and the multiple rotation shafts 221a of the first side wall 22 are rotatably supported by the multiple bearings 31b of the lid 3. This allows the lid 3 to be rotatably connected to the first side wall 22. A single imaginary line passing through the centers of the shaft bodies 310 of the multiple rotation shafts 31a of the lid 3 is the central axis L1, which is the center of rotation of the lid 3.

[0057] The connecting portion 31 of the lid 3 and the lid connecting portion 221 of the first side wall 22 are configured so that there are small gaps between the support portion 311 of the lid 3 and the bearing 221b of the first side wall 22, and between the bearing 31b of the lid 3 and the support portion 2211 of the first side wall 22. The length of each gap in the front-to-rear direction is narrower than the length of each groove 35 in the front-to-rear direction (i.e., the width of each groove 35). This allows the rib 224 to be stored in each groove 35 even if the lid 3 shifts laterally (shifts in the front-to-rear direction).

[0058] 2-2-3. Lid locking member The lid locking member 5 is fitted into the recess 37 and has an operating part 50 that is operated by the user, and a locking claw 51 that protrudes outward in the front-to-rear direction from the operating part 50. The lid locking member 5 is slidable between a locked position where the locking claw 51 protrudes outward in the front-to-rear direction from the lid 3, and an unlocked position where the locking claw 51 does not protrude outward in the front-to-rear direction from the lid 3.

[0059] When the lid 3 is in the covering position, the operating part 50 of the lid locking member 5 is operated to move the lid locking member 5 from the unlocked position to the locked position, causing the locking claw 51 to protrude from the lid 3 and be inserted into the locking hole 234 of the second side wall 23. This locks the lid 3 in the covering position to the second side wall 23.

[0060] By operating each of the two lid locking members 5 of the lid 3 and inserting each of the two locking claws 51 into the locking holes 234 of the pair of second side walls 23, the lid 3 is locked in the covering position relative to each of the pair of second side walls 23.

[0061] 2-3.Other The transport container 1 of this embodiment is configured so that when multiple transport containers 1 with their lids 3 in the covering position are stacked one on top of the other, a gap is formed between the upper surface of the lid 3 of the lower transport container 1 and the rib 2101 of the bottom wall 21 of the upper transport container 1. This gap is narrower than the thickness of the top plate 300 of the lid 3.

[0062] In addition, if the lid 3 or bottom wall 21 is deformed by being pressed by the contents contained in each transport container 1, the upper surface of the lid 3 of the lower transport container 1 and the rib 2101 of the bottom wall 21 of the upper transport container 1 may abut.

[0063] 3.How to use In the transport container 1 of this embodiment described above, each of the pair of lids 3 can be rotated about the central axis L1 to move between the covering position shown in Figures 1, 2A, and 2B and the open position shown in Figures 3, 4A, and 4B. The pair of lids 3 are fixed in the covering position by being locked to each of the pair of second side walls 23 by two lid locking members 5.

[0064] When the pair of lids 3 are in the covering position, as shown in FIG. 2A, the first portion 30a of the lid body 30 is located below the central axis L1, and the lower surface of the second portion 30b of the lid body 30 is located above the lower surface of the first portion 30a. At this time, the lower surface of the main body portion 30d of the second portion 30b is located above the upper surface of the first portion 30a, and the upper end surface of the second portion 30b is located at approximately the same height as a part of the upper surface of the second side wall 23. At this time, the first portion 30a and the main body portion 30d of the second portion 30b are located parallel or approximately parallel to the bottom wall main body 210. At this time, as shown in FIG. 2B, the bottom surface 350 of the groove 35 (i.e., the upper surface of the bottom plate portion 305) is located below the central axis L1.

[0065] 4A and 4B, when the pair of lids 3 are in the open position, the first portion 30a of the lid body 30 abuts against the ribs 223 (horizontal ribs 223a or vertical ribs 223b) at the upper end of the first side wall 22 and extends in a substantially vertical direction outside the first side wall 22. At this time, the main body portion 30d of the second portion 30b of the lid body 30 is fitted into the multiple recesses 225 of the first side wall 22, and the multiple ribs 224 of the first side wall 22 are fitted one by one into the multiple grooves 35 of the second portion 30b, as shown in FIG. 5. The main body portion 30d extends in a substantially vertical direction within the recesses 225 and is fitted within the thickness of the first side wall 22.

[0066] 4A and 4B, when the lid 3 is in the open position, the entire main body portion 30d of the second portion 30b of the lid is contained within the recess 225 of the first side wall 22 and does not protrude outside the container. At this time, the main body portion 30d of the second portion 30b of the lid and the side wall main body 222 of the first side wall 22 are parallel or approximately parallel. At this time, the gap between the top plate 300 and the side wall main body 222 of the first side wall 22 in the main body portion 30d of the second portion 30b of the lid is larger than the gap between the bottom surface of the groove 35 of the lid 3 and the rib 224 of the first side wall 22.

[0067] 4. Effects In the transport container 1 of this embodiment described above, as shown in Figure 2A, when the lid 3 is in the covering position, the first portion 30a of the lid body 30 is located below the central axis L1, and the lower surface of the second portion 30b of the lid body 30 is located above the lower surface of the first portion 30a.

[0068] Therefore, in the transport container 1 of this embodiment, the storage space below the lid body 30 (particularly the storage space below the second part 30b) can be made wider in the vertical direction compared to when the entire lid body 30 is composed of only the first part 30a.

[0069] Furthermore, in the transport container 1 of this embodiment, as shown in FIG. 2A, the main body portion 30d of the second part 30b of the lid body 30 occupies more than half of the width of the lid body 30, making it easy to ensure that the storage space formed below the lid body 30 is wide in the vertical direction.

[0070] Furthermore, in the transport container 1 of this embodiment, the lid body 30 is composed of the top plate 300 and ribs 301, 302, and 303 (see FIG. 8), and when the lid 3 is in the covering position, recesses formed between the ribs 301, 302, and 303 open downward (see FIG. 2A). Therefore, in the transport container 1 of this embodiment, the gaps between the ribs 301, 302, and 303 (i.e., the internal space of the lid body 30) can also be used as storage space.

[0071] Furthermore, in the transport container 1 of this embodiment, the ribs 301, 302, and 303 that make up the lid body 30 are connected to one another, so that the lid body 30 can be made hollow while still ensuring strength.

[0072] Furthermore, in the transport container 1 of this embodiment, the second rib 302b of the lid body 30 is positioned from one end to the other end of the lid body 30 in the width direction, so that the lid body 30 can be curved midway in the width direction while still ensuring the strength of the lid body 30.

[0073] Furthermore, in the transport container 1 of this embodiment, by positioning the first portion 30a of the lid body 30 of the lid 3 so as to be offset in the thickness direction of the lid body 30 with respect to the central axis L1, it is easy to prevent interference between the rib 223 at the upper end of the first side wall 22 and the lid body 30 when in the open position, as shown in Fig. 4A. Therefore, in the transport container 1 of this embodiment, it is easy to position the lid 3 vertically when in the open position, and it is easy to reduce the amount of protrusion outside the container (i.e., outward in the left-right direction).

[0074] 4A, when the lid 3 is in the open position, the main body portion 30d of the second portion 30b of the lid body 30 of the lid 3 is positioned closer to the container body 2 (i.e., more inward in the left-right direction) than the first portion 30a. Therefore, in the transport container 1 of this embodiment, it is easier to reduce the amount of protrusion of the lid 3 outward from the container (i.e., outward in the left-right direction) when the lid 3 is in the open position, compared to when the lid body 30 is entirely composed of the first portion 30a.

[0075] 4B, when the lid 3 is placed in the open position, the plurality of ribs 224 of the first side wall 22 can be accommodated in the plurality of grooves 35 of the second portion 30b of the lid main body 30. Therefore, in the transport container 1 of this embodiment, the first side wall 22 is reinforced by the plurality of ribs 224, and it is easy to prevent interference between the second portion 30b of the lid main body 30 and the plurality of ribs 224 of the first side wall 22 when the container is in the open position. As a result, in the transport container 1 of this embodiment, it is easy to position the lid 3 vertically when the container is in the open position, and it is easy to reduce the amount of protrusion of the lid 3 outside the container (i.e., outward in the left-right direction).

[0076] Furthermore, in the transport container 1 of this embodiment, when the lid 3 is placed in the open position, the multiple ribs 224 of the first side wall 22 can be accommodated in the multiple grooves 35 of the lid body 30, which makes it easy to accommodate the main body portion 30d of the second portion 30b in the recess 225 of the first side wall 22, as shown in Fig. 4A. Therefore, in the transport container 1 of this embodiment, when the lid 3 is placed in the open position, the main body portion 30d of the second portion 30b of the lid 3 can be accommodated within the thickness of the first side wall 22, which makes it easy to reduce the amount of protrusion of the lid 3 outward from the outermost surface of the first side wall 22.

[0077] 5. Variations Next, a description will be given of modified examples of the transportation container 1 according to the above-described embodiment. The modified examples described below can be combined as appropriate.

[0078] The lid 3 of the transport container 1 may be configured so that when the lid 3 is in the covering position, the upper end surface of the second portion 30b (i.e., the upper surface of the main body portion 30d) is positioned at the same level as or below the central axis L1.

[0079] The outer surface of the container body 2 may not be provided with a recess 225 capable of accommodating the second portion 30b when the lid 3 is in the open position. Furthermore, the outer surface of the container body 2 may not be provided with a rib 224. That is, the first side wall 22 may be a solid, flat wall. In this case, the lid body 30 may not be provided with a groove 35 capable of accommodating the rib 224. Furthermore, when the lid 3 is in the open position, it may be along the outer surface of the container body 2 while being slightly tilted with respect to the vertical direction.

[0080] When the lid 3 is in the covering position, the transport container 1 may have the bottom surface 350 of the groove 35 of the lid body 30 positioned at the same height as the central axis L1 or positioned above the central axis L1.

[0081] In the lid 3, the main body portion 30d of the second portion 30b of the lid main body 30 does not have to be linear. As shown in a modified example in FIG. 9, the main body portion 30d may include two linearly extending portions 30e and 30f and an inclined portion 30g connecting the two portions 30e and 30f. The portion 30g is inclined so that the portion farther from the connecting portion 31 is positioned lower, and the portion 30f is positioned lower than the portion 30e. When the lid 3 is in the covering position, the upper surface of the portion 30f is positioned lower than the central axis L1. Furthermore, the lower surface of the portion 30f is positioned higher than the lower surface of the first portion 30a. Even in the modified lid 3, when the lid 3 is in the covering position, the lower surface of the second portion 30b of the lid main body 30 is positioned higher than the lower surface of the first portion 30a, thereby ensuring a wide storage space in the vertical direction below the lid main body 30 when in the covering position.

[0082] The transport container 1 is not limited to the structure shown in Figures 1 and 3. The container body 2 is not limited to a rectangular parallelepiped in plan view, and may be a box of other shapes.

[0083] The pair of lids 3 may be provided so that the ends of adjacent sides overlap in the vertical direction. In this case, it is preferable that one of the lids 3 has a structure like the modified example shown in FIG.

[0084] Furthermore, the container body 2 may be provided in a non-foldable manner.

[0085] Furthermore, the lid 3 does not have to be configured with the top plate 300 and the plurality of ribs 301, 302, 303, and may be formed in the shape of a solid plate.

[0086] Furthermore, in order to increase the strength of the side surfaces of the container body 2, the transport container 1 may be provided with horizontal ribs extending long in the front-to-rear direction at the portions of the first side wall 22 where the horizontal ribs 224 intersect. The horizontal ribs are provided shorter in the left-to-right direction than the ribs 224. In this case, a groove portion that is long in the front-to-rear direction and capable of accommodating the horizontal ribs is provided in the lid body 30. The groove portion is provided shallower than the groove 35. This makes it possible to increase the strength of the side surfaces of the container body 2 while suppressing a decrease in the strength of the lid 3.

[0087] (summary) As in the embodiment and its modified example described above, the transport container 1 of the first aspect has the following configuration.

[0088] That is, the transport container 1 of the first embodiment comprises a box-shaped container body 2 having an opening 20 on its upper surface, and a lid 3 connected to the container body 2 so as to move between a covering position where the opening 20 is covered and an open position where the opening 20 is opened along the outer surface of the container body 2. The lid 3 has a plate-shaped lid body 30 that covers or opens the opening 20, and a connecting portion 31 that protrudes from one end of the lid body 30 and is rotatably connected to the upper end of the container body 2. The lid 3 is rotatable around a central axis L1 located at the connecting portion 31. The lid body 30 includes a first portion 30a located on the connecting portion 31 side and a second portion 30b located on the opposite side from the connecting portion 31. When the lid 3 is in the covering position, the first portion 30a is located below the central axis L1, and the lower surface of the second portion 30b is located above the lower surface of the first portion 30a.

[0089] In the transport container 1 of the first embodiment having the above-described configuration, when the lid 3 is in the covering position covering the opening 20 of the container body 2, the underside of the second portion 30b of the lid body 30 is located higher than the underside of the first portion 30a. Therefore, in the transport container 1 of the first embodiment, a larger storage space can be secured in the vertical direction below the lid body 30 of the lid 3 in the covering position compared to when the lid body 30 is entirely composed of the first portion 30a. Furthermore, in the transport container 1 of the first embodiment, when the lid 3 is rotated and positioned so as to fit along the outer surface of the container body 2, the second portion 30b is located closer to the container body 2 than the first portion 30a, making it easier to reduce the amount of protrusion of the lid 3 outside the container when in the open position.

[0090] As in the embodiment and its modification described above, the transport container 1 of the second aspect additionally comprises the following configuration in addition to the configuration of the first aspect.

[0091] That is, in the transport container 1 of the second embodiment, when the lid 3 is in the covering position, the upper end surface of the second portion 30b is located above the central axis L1.

[0092] In the second embodiment of the transport container 1 having the above-described configuration, the second portion 30b is located at a high position such that the upper end surface of the second portion 30b is positioned above the central axis L1, making it easy to ensure a wide storage space below the second portion 30b in the vertical direction.

[0093] As in the embodiment and its modification described above, the transport container 1 of the third aspect additionally comprises the following configuration in addition to the configuration of the second aspect.

[0094] That is, in the transport container 1 of the third embodiment, the outer surface of the container body 2 is provided with a recess 225 capable of accommodating the second portion 30b when the lid 3 is in the open position.

[0095] In the transport container 1 of the third embodiment having the above configuration, when the lid 3 is in the open position, the second portion 30b of the lid 3, which is located closer to the container body 2 than the first portion 30a, can be accommodated in the recess 225 on the outer surface of the container body 2. Therefore, in the transport container 1 of the third embodiment, the lid 3 in the open position can be easily arranged along the outer surface of the container body 2.

[0096] As in the embodiment and its modification described above, the transport container 1 of the fourth aspect additionally comprises the following features in addition to the features of the second or third aspect.

[0097] That is, in the transport container 1 of the fourth embodiment, ribs 224 are provided on the outer surface of the container body 2. The lid body 30 is provided with grooves 35 that can accommodate the ribs 224 when the lid 3 is in the open position.

[0098] In the fourth embodiment of the transport container 1 having the above configuration, the ribs 224 can reinforce the outer surface of the container body 2, and it is easy to prevent the lid 3 from hitting the ribs 224 when in the open position, thereby increasing the amount of protrusion outside the container.

[0099] As in the embodiment and its modification described above, the transport container 1 of the fifth aspect additionally comprises the following features in addition to the features of the fourth aspect.

[0100] That is, in the transport container 1 of the fifth embodiment, when the lid 3 is in the covering position, the bottom surface 350 of the groove 35 of the lid body 30 is located below the central axis L1.

[0101] In the transport container 1 of the fifth embodiment having the above configuration, the groove 35 of the lid body 30 can be made deep, and therefore the rib 224 provided on the outer surface of the container body 2 can be made high. Therefore, in the transport container 1 of the fifth embodiment, the strength of the container body 2 against compressive loads can be increased, and the occurrence of bulging of the container body 2 can be suppressed.

[0102] The present disclosure has been described above based on the embodiments shown in the accompanying drawings, but the present disclosure is not limited to the above embodiments, and appropriate design changes are possible within the intended scope of the present disclosure.
