Effects In the transport container 1 of this embodiment described above, a pair of operating parts 58a, 58b that can be hooked with fingers from the outside of the oscillating side walls 5 are provided at the lower end of each of the pair of oscillating side walls 5. Therefore, in the transport container 1 of this embodiment, since fingers can be hooked on the pair of operating parts 58a, 58b from the outside of the transport container 1 and pulled, it is easy to move the pair of oscillating side walls 5 to an upright position and assemble the container.

[0056] In addition, in the transport container 1 of this embodiment, the inner ends P1 in the width direction D1 of each of the pair of operating parts 58 (first operating part 58a and second operating part 58b) are located inside the width direction D1 of the oscillating side wall 5 at a position closer to the center P2 in the width direction D1 than the midpoint P4 between the center P2 and the outer edge P3.

[0057] Furthermore, the distance L1 from the first engagement portion 520a to the first operating portion 58a in the width direction D1 is shorter than the distance L2 from the first operating portion 58a to the first outer edge P30. The distance L3 from the second engagement portion 520b to the second operating portion 58b in the width direction D1 is shorter than the distance L4 from the second operating portion 58b to the second outer edge P31.

[0058] The operating portion 58 (first operating portion 58a and second operating portion 58b) is disposed at the end of the mounting region A1 side in the region A2 beside the mounting region A1.

[0059] Therefore, in the transport container 1 of this embodiment, the pair of operating parts 58a, 58b can be arranged as close as possible to the pair of engaging parts 520a, 520b while not interfering with the label holding member 8. As a result, in the transport container 1 of this embodiment, the force for operating the pair of operating parts 58a, 58b is easily transmitted to the pair of engaging parts 520a, 520b, facilitating the operation of engaging the swingable side wall 5 with the bottom wall 2. From this perspective, the transport container 1 of this embodiment is easy to assemble.

[0060] Furthermore, in the transport container 1 of this embodiment, the pair of operating portions 58a, 58b are continuous with the pair of engaging portions 520a, 520b, which are part of the horizontal rib 56b, via the horizontal rib 56a and the vertical rib 56c. Therefore, in the transport container 1 of this embodiment, the swinging side wall 5 is rigid, and the force for operating the pair of operating portions 58a, 58b is easily transmitted to the pair of engaging portions 520a, 520b.

[0061] Furthermore, in the transport container 1 of this embodiment, the pair of operating parts 58a, 58b are integral with the horizontal rib 56a and are positioned adjacent to the pair of engaging parts 520a, 520b in the vertical direction, so that the force operating the pair of operating parts 58a, 58b is easily transmitted to the pair of engaging parts 520a, 520b.

[0062] Furthermore, in the transport container 1 of this embodiment, the pair of operating parts 58a, 58b have curved plate parts 580 that bulge outward beyond the horizontal rib 56a, thereby widening the insertion space S2 formed inside the curved plate parts 580. Therefore, in the transport container 1 of this embodiment, it is easy to hook the pair of operating parts 58a, 58b with your fingers and pull them.

[0063] Furthermore, in the transport container 1 of this embodiment, the curved plate portion 580, which bulges outward to protrude beyond the horizontal ribs 56a, is continuous with the horizontal ribs 56a via the closure plate portion 581, and therefore the curved plate portion 580 can be reinforced by the closure plate portion 581. Therefore, in the transport container 1 of this embodiment, when operating the curved plate portion 580 by hooking a finger on it, the curved plate portion 580 is less likely to deform, and the force used to operate the pair of operating portions 58a, 58b is easily transmitted to the pair of engaging portions 520a, 520b.

[0064] In addition, in the transport container 1 of this embodiment, the pair of operating parts 58a, 58b are positioned so as not to interfere with the label holding member 8, so the pair of operating parts 58a, 58b are less likely to interfere with the label holding member 8 holding the label.

[0065] Furthermore, in the transport container 1 of this embodiment, each of the pair of operating portions 58a, 58b is provided across the main body portion 55 and the protruding portion 54 of the main plate 50 of the oscillating side wall 5, so that the pair of operating portions 58a, 58b can be reinforced by the protruding portion 54.

[0066] Furthermore, in the transport container 1 of this embodiment, one end of the curved plate portion 580 of the pair of operating portions 58a, 58 is integrally formed with the protrusion 54, which makes it possible to reduce the circumferential length of the curved plate portion 580, thereby making it easier to ensure the strength of the curved plate portion 580.

[0067] 4. 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.

[0068] The swingable side wall 5 is not limited to the structure shown in FIGS.

[0069] The operating portion 58 may not have the closure plate portion 581, and may be located above and away from the horizontal rib 56a, and the insertion space S2 may be a space that is open both upward and downward.

[0070] As in Modification 1 shown in Fig. 5A, the protruding portion 54 may be constituted by at least one vertical rib 542 that protrudes outward from an end of the main plate 50 in the width direction D1 and extends in the up-down direction. In Modification 1, the protruding portion 54 is constituted by two vertical ribs 542 that are parallel to each other. The curved plate portion 580 of the operating part 58 is continuous with the vertical rib 542 and the main body portion 55 of the main plate 50. The length in the front-to-rear direction of the curved plate portion 580 is the same as the length in the front-to-rear direction of the upper horizontal rib 56a, and the positions of the outer ends in the front-to-rear direction (rear edges in the figure) of the curved plate portion 580 and the horizontal rib 56a are the same.

[0071] The curved plate portion 580 has a flat outer plate portion 582 extending parallel to the main body portion 55 of the main plate 50, and a flat connecting plate portion 583 protruding inward from the inner end of the outer plate portion 582 in the width direction D1 and continuing to the main body portion 55. In this modified example, the connecting plate portion 583 is an inclined plate that is inclined with respect to the outer plate portion 582. The operating portion 58 is composed only of the curved plate portion 580 and does not have a closing plate portion 581. The lower end of the curved plate portion 580 is integral with the horizontal rib 56a over the entire length of the curved plate portion 580.

[0072] 5B, the operating portion 58 may be integral only with the protruding portion 54 and the horizontal rib 56a, and may be discontinuous with the main body portion 55 of the main plate 50. In the second modification, the operating portion 58 is formed of a flat plate portion 584. The outer end (the left end in the drawing) of the flat plate portion 584 in the width direction D1 is integral with the vertical rib 542 that constitutes the protruding portion 54, and the lower end of the flat plate portion 584 is integral with the horizontal rib 56a. The flat plate portion 584 is parallel to the main body portion 55 of the main plate 50. The flat plate portion 584 is a flat plate having a right-angled triangular shape when viewed from the front. Note that the shape of the flat plate portion 584 when viewed from the front is not limited to a right-angled triangular shape.

[0073] 6A, the operating unit 58 may have a connecting plate portion 583 of the curved plate portion 580 that is continuous with the outer plate portion 582 at a right angle. The main body portion 55 of the main plate 50 may have an inner curved portion 550 that is curved in an arc shape that convex inward (toward the front in the figure) in a plan view at a portion facing the outer plate portion 582 and above the portion. The outer plate portion 582 is continuous with the central plate portion 540 of the protruding portion 54 so that their outer surfaces are flush with each other. The central plate portion 540 and the outer plate portion 582 are located inside the outer edges of the horizontal ribs 56a. An insertion space S2 into which a finger can be inserted is defined between the outer plate portion 582 and the inner curved portion 550. The outer plate portion 582 forms a finger hook 60 having an upper end that extends linearly in the width direction D1 of the swinging side wall 5. The inner curved portion 550 has an inwardly convex arc shape, which makes it easy to ensure that the insertion space S2 is wide in the front-rear direction.

[0074] Furthermore, the main body portion 55 of the main panel 50 may have an opening 551 at a portion facing the outer panel portion 582 and above the portion, as in Modification 4 shown in FIG. 6B. The opening 551 is longer upward than the outer panel portion 582. In this case, the space located inside the outer panel portion 582 is the insertion space S2. In Modification 4, there is no wall facing the inner side of the outer panel portion 582, making it easy for a user to insert their finger into the insertion space S2. Note that a portion of the protrusion 54 surrounding the insertion space S2 may be a vertical rib 542 (see FIG. 5A) that protrudes linearly outward (toward the rear in the figure). In other words, the curved panel portion 580 surrounding the insertion space S2 and a portion of the protrusion 54 (i.e., the vertical rib 542) may have a U-shaped cross section perpendicular to the up-down direction that opens inward (toward the front in the figure). In addition, the inclined plate portion 541 may be inclined so that the more inward (front in the figure) the portion is located, the more outward in the width direction D1 (left side in the figure), and the connecting plate portion 583 of the curved plate portion 580 may be inclined so that the more inward (front in the figure) the portion is located, the more inward in the width direction D1 (right side in the figure) (see FIG. 5A). In other words, the cross-sectional shape of the inclined plate portion 541 and the connecting plate portion 583 perpendicular to the up-down direction may be an inverted V shape in which the distance between the inclined plate portion 541 and the connecting plate portion 583 becomes wider as it approaches the inner side (front side in the figure).

[0075] 6C , the operating unit 58 may further include a connecting plate portion 583a in which the curved plate portion 580 extends inward from the outer end (the left end in the drawing) of the outer plate portion 582 in the width direction D1 and is continuous with the protruding portion 54. Each of the connecting plate portions 583, 583a is continuous with the outer plate portion 582 at a right angle. The outer plate portion 582 protrudes outward beyond the protruding portion 54, and the outer surface of the outer plate portion 582 and the outer surface of the horizontal rib 56a are aligned flush with each other. The space between the outer plate portion 582 and the main body portion 55 of the main panel 50 is the insertion space S2. In the fifth modification, the operating unit 58 is configured with the curved plate portion 580 that is bent so as to protrude outward beyond the protruding portion 54, making it easy to ensure that the insertion space S2 is wide in the front-to-rear direction.

[0076] 7A, a protrusion 5851 that protrudes inward in the thickness direction D2 of the swinging side wall 5 and that can be hooked by a finger may be provided at the upper end of the operating part 58. FIG. 7A shows a second operating part 58b.

[0077] In the sixth modification, the operating portion 58 is configured with a cantilever 585 that protrudes inward in the left-right direction from the protruding portion 54. The cantilever 585 is not continuous with the upper horizontal rib 56a (see FIG. 2) or the main body 55 of the main board 50. The cantilever 585 has a flat vertical piece 5850 that is parallel to the main body 55 of the main board 50, and a convex portion 5851 that protrudes inward from the upper end of the vertical piece 5850.

[0078] The convex portion 5851 may be provided on a portion of the upper end portion of the vertical piece 5850 in the left-right direction, or may be provided over the entire length of the upper end portion of the vertical piece 5850 in the left-right direction. The cantilever piece 585 is provided such that the outer end portion of the vertical piece 5850 in the left-right direction is integral with the outermost surface of the protrusion 54 (i.e., the outer surface of the central plate portion 540 or the outer surface of the vertical rib 542). Note that the cantilever piece 585 only needs to be integral with the protrusion 54, and may be provided integrally with not only the outermost surface but also an inner surface in the left-right direction (i.e., the inner surface in the left-right direction of the inclined plate portion 541 or the vertical rib 542). The space between the cantilever piece 585 and the main body 55 is the insertion space S2.

[0079] In the sixth modification, when a finger is placed on the cantilever piece 585 from above, the finger can be easily caught on the convex portion 5851, so that the finger is less likely to slip, and the operation unit 58 can be easily operated.

[0080] 7B, the cantilever 585 may have a vertical piece 5850 and an inclined piece 5852 extending diagonally upward and outward from the upper end of the vertical piece 5850. FIG. 7B shows a second operating portion 58b. In this case, the insertion space S2 is defined between the vertical piece 5850, the inclined piece 5852, and the main body 55 facing the inside of the vertical piece 5850 and the inclined piece 5852. The inclined piece 5852 forms a finger hook 60 having an upper end extending linearly in the width direction D1 of the swinging sidewall 5. In the seventh modification, the inclined piece 5852 is inclined so that the upper portion is positioned further outward, making it easier to ensure a wider insertion space S2 in the front-to-rear direction and to insert a finger.

[0081] Furthermore, as in variant 8 shown in Figure 7C and variant 9 shown in Figures 8A and 8B, the operating portion 58 is composed of a plate-shaped portion 59 protruding outward from the oscillating side wall 5, and a portion of the upper end surface of the plate-shaped portion 59 may protrude upward.

[0082] In Modification 8 shown in Fig. 7C, operating portion 58 is configured with plate-shaped horizontal piece 586 that protrudes outward from main body 55 of main plate 50 and has a thickness in the vertical direction. Fig. 7C shows second operating portion 58b. The upper surface of horizontal piece 586 is provided with multiple protrusions 5860 for hooking fingers. In Modification 8, horizontal piece 586 is plate-shaped portion 59 that protrudes outward from swinging sidewall 5, and multiple protrusions 5860 are portions that protrude upward from a part of the upper end surface of plate-shaped portion 59.

[0083] In this modified example, each of the multiple protrusions 5860 is a long, narrow rib extending in the left-right direction. The multiple protrusions 5860 are positioned at intervals in the front-rear direction. The horizontal piece 586 is not continuous with the horizontal rib 56a (see FIG. 2) and the protrusion 54. The horizontal piece 586 may be provided so as to be continuous with the protrusion 54. The swingable side wall 5 does not have an insertion space S2 located inside the operating portion 58.

[0084] In the eighth modification, the user can hook their fingers on multiple protrusions 5860 on the upper surface of side piece 586 and pull side piece 586 outward. At this time, since the fingers can easily hook on multiple protrusions 5860 on the upper surface of side piece 586, the operation of pulling side piece 586 can be easily performed. The user may also pinch side piece 586 from above and below with their fingers and pull it outward.

[0085] In Modification 9 shown in FIGS. 8A and 8B, the operating unit 58 is configured with a plurality of flat vertical pieces 587 that protrude outward from the main body 55 of the main board 50 and have a thickness in the left-right direction. The vertical pieces 587 are positioned at intervals in the left-right direction. In this modification, each of the vertical pieces 587 is trapezoidal in shape when viewed from the side. The vertical pieces 587 have the same shape. The upper surface 5870 of each vertical piece 587 is an inclined surface that is inclined so that the outer portions are positioned higher. The lower surface 5871 of each vertical piece 587 is an inclined surface that is inclined so that the outer portions are positioned lower.

[0086] In the ninth modification, the vertical pieces 587 are plate-like portions 59 that protrude outward from the swinging sidewall 5, and the outer end of the upper surface 5870 of each vertical piece 587 is a part of the upper end surface of the plate-like portion 59 that protrudes upward. Note that the swinging sidewall 5 does not have the insertion space S2 located inside the operating portion 58.

[0087] Each vertical piece 587 is not continuous with the horizontal rib 56a (see FIG. 2) and the protrusion 54. In the ninth modification, the user can hook a finger on the upper surface 5870 of each vertical piece 587 and pull it outward. At this time, the finger can fit into the gap S3 between the vertical pieces 587, making it easier to pull the vertical pieces 587 outward. In addition, at this time, the upper surface 5870 of each vertical piece 587 is an inclined surface that is positioned higher toward the outer side, making it easier for the finger to hook onto each vertical piece 587. The user may pinch each vertical piece 587 with their fingers from above and below and pull it outward. The shape of each vertical piece 587 in a side view is not limited to a trapezoidal shape.

[0088] 9A and 9B, the operating unit 58 may further include a plate-shaped reinforcing rib 588 that reinforces the curved plate portion 580. The outer plate portion 582 of the curved plate portion 580 is not flat, but is curved in an arc shape that convex outward. The reinforcing rib 588 includes a first reinforcing rib 588a that is disposed at the corner between the outer plate portion 582 and the protruding portion 54, and a second reinforcing rib 588b that is disposed at the corner between the outer plate portion 582 and the connecting plate portion 583. Each of the reinforcing ribs 588a and 588b is flat and has a thickness in the up-down direction, and is generally triangular in plan view.

[0089] The first reinforcing rib 588a is continuous with the inner surface of the outer plate portion 582 and the outer surface of the inclined plate portion 541 of the protruding portion 54. The second reinforcing rib 588b is continuous with the inner surface of the outer plate portion 582 and the outer surface in the left-right direction of the connecting plate portion 583. The curved plate portion 580 is located above the horizontal rib 56a and is not continuous with the horizontal rib 56a.

[0090] In the tenth modification, curved plate portion 580 of operation unit 58 can be reinforced by two reinforcing ribs 588a, 588b, so that when a finger is hooked on curved plate portion 580 and the operation is performed by pulling, curved plate portion 580 is less likely to deform and the force for operating operation unit 58 is easily transmitted to engagement portion 520. Note that reinforcing rib 588 may be provided so as to be continuous with main body portion 55 of main plate 50 and curved plate portion 580.

[0091] Furthermore, as in variant example 11 shown in Figure 10A, the operating part 58 is composed of a single plate-shaped horizontal piece 586 that protrudes outward from the oscillating side wall 5 and has a thickness in the vertical direction, and a protrusion 5861 may be provided on at least one of the upper and lower surfaces of the horizontal piece 586.

[0092] In this modification, the side piece 586 is flat, and a protrusion 5861 for hooking a finger is provided on the underside of the side piece 586. The protrusion 5861 is a single elongated rib extending in the left-right direction and is provided on the outer end (rear end in the figure) of the underside of the side piece 586. The protrusion 5861 is located over the entire length of the side piece 586 in the left-right direction. The protrusion 5861 protrudes from the underside of the side piece 586 not only at the outer end but also at a position closer to the center than the outer portion, as in modification 12 shown in FIG. 10B, as long as it is a position where a finger gripping the side piece 586 can be hooked. The protrusion 5861 is not limited to a single elongated rib extending in the left-right direction, but may also be a group of multiple ribs spaced apart in the left-right direction, or may be one or more ribs located in the center in the left-right direction.

[0093] Furthermore, a plurality of protrusions 5861 may be provided at intervals in the front-rear direction on the lower surface of side piece 586. Furthermore, one or more protrusions 5861 may be provided not only on the lower surface but also on the upper surface of side piece 586. Furthermore, one or more protrusions 5861 may be provided only on the upper surface of side piece 586 (see FIG. 7C).

[0094] In Modifications 11 and 12, the user can pinch side piece 586 between the top and bottom of the fingers and pull it outward. At this time, the fingers can easily catch on protrusion 5861 on the bottom surface of side piece 586, making it easy to pull side piece 586. The user may also hook their fingers only on the surface of the top or bottom surface of side piece 586 where protrusion 5861 is provided and pull it outward.

[0095] Furthermore, as shown in variants 13 to 16 in Figures 11A to 11D, the operating portion 58 is composed of a single plate-shaped vertical piece 587 that protrudes outward from the oscillating side wall 5 and has a thickness in the width direction D1 (left-right direction in the figure), and the vertical piece 587 may be provided with a protrusion 5872 that protrudes in at least one direction in the width direction D1.

[0096] 11A, the vertical piece 587 has a flat plate shape and a rectangular shape in a side view. Protrusions 5872 protrude from the leading end of the vertical piece 587 in the protruding direction (the rear end in the figure) on both sides in the width direction D1 (on both the left and right sides in the figure). The protrusions 5872 are positioned over the entire length of the vertical piece 587 in the up-down direction.

[0097] 11B, protrusions 5872 protrude on both sides in the width direction D1 (on both the left and right sides in the drawing) from the center in the protruding direction of the vertical piece 587 (more specifically, a portion slightly toward the tip end from the midpoint in the protruding direction). The protrusions 5872 are positioned over the entire length of the vertical piece 587 in the up-down direction.

[0098] In the fifteenth modification shown in FIG. 11C, protrusions 5872 protrude from the upper and lower ends of the tip of the vertical piece 587 in the protruding direction on both sides in the width direction D1 (on both the left and right sides in the drawing).

[0099] 11D, a protrusion 5872 protrudes to one side in the width direction D1 (the right side in the drawing) from the tip end in the protruding direction of a vertical piece 587. The protrusion 5872 is located over the entire length of the vertical piece 587 in the up-down direction.

[0100] The shape of vertical piece 587 in modifications 13 to 16 in a side view is not limited to a rectangle, and may be a trapezoid in which the distance between the upper surface and the lower surface increases toward the tip (see FIG. 8A), a trapezoid in which the distance between the upper surface and the lower surface decreases toward the tip, or a semicircular shape. Furthermore, protrusion 5872 only needs to be provided at the portion of vertical piece 587 where the finger rests, and may be provided only at the middle portion of vertical piece 587 or at other portions.

[0101] In Modifications 13 to 16, the user can pinch vertical piece 587 with his or her fingers from the left and right and pull it outward. At this time, the user can easily pull vertical piece 587 because the fingers can easily catch on protrusions 5872 on the side surfaces of vertical piece 587. The user may also hook his or her fingers only on the surface of the left or right side surface of vertical piece 587 on which protrusions 5872 are provided and pull it outward.

[0102] Furthermore, the transport container 1 is not limited to the structure shown in FIG.

[0103] The side walls 4 may be any wall that includes a swingable side wall 5 that is rotatably connected to the mouth frame 3 and engages with the bottom wall 2, and are not limited to a wall that includes a pair of swingable side walls 5 and a pair of folding side walls 6. For example, the side walls 4 may include only one swingable side wall 5. Furthermore, the side walls 4 may not include a pair of folding side walls 6, and may include a non-foldable side wall instead of the pair of folding side walls 6.

[0104] Moreover, the swingable side wall 5 may have only one operating portion 58. Moreover, the swingable side wall 5 may have only one engaging portion 520.

[0105] The transport container 1 may also be provided with a single lid 7 that opens and closes the entire inner opening 30 of the mouth frame 3. The transport container 1 does not necessarily have to be provided with a lid 7.

[0106] Furthermore, the transport container 1 does not necessarily have to include the label holding member 8. In this case, the label may be attached to the main body portion 55 of the main plate 50 of the swinging side wall 5.

[0107] Furthermore, the transport container 1 is not limited to a rectangular box shape, and may be a box of other shapes.

[0108] Furthermore, the engaging portion 520 is not limited to being provided only at the center in the width direction D1 of the lower end of the swinging side wall 5, and may also be provided at other portions. For example, another engaging portion may be provided at a portion of the lower horizontal rib 56b that is located below the operating portion 58 so as to fit within the width of the operating portion 58. Another engaging portion may also be provided at a portion of the lower horizontal rib 56b that is located outside the operating portion 58 in the width direction D1.

[0109] (summary) As in the embodiment and its modified example described above, the transport container 1 of the first aspect has the following configuration.

[0110] That is, the transport container 1 of the first embodiment includes a bottom wall 2, a mouth frame 3 that is frame-shaped in plan view and located above the bottom wall 2, and multiple side walls 4 attached between the mouth frame 3 and the bottom wall 2. The multiple side walls 4 include a swinging side wall 5 that is rotatably connected to the mouth frame 3 and engages with the bottom wall 2. The swinging side wall 5 is located apart from each other in a width direction D1 of the swinging side wall 5, which is a direction along the circumferential direction of the mouth frame 3, and has a pair of operating parts 58 that can be hooked with fingers from the outside of the swinging side wall 5 and pulled, and an engaging part 520 that is located inside the pair of operating parts 58 in the width direction D1 and engages with the bottom wall 2. An inner end P1 in the width direction D1 of each of the pair of operating parts 58 is located inside a midpoint P4 between a center P2 and an outer edge P3 of the swinging side wall 5 in the width direction D1.

[0111] In the transport container 1 of the first embodiment having the above-described configuration, the oscillating side wall 5 has a pair of operating parts 58 that can be hooked with fingers from the outside of the oscillating side wall 5 and pulled, and the pair of operating parts 58 are located near the center of the oscillating side wall 5 in the width direction D1, making it easy to arrange the pair of operating parts 58 near the engaging parts 520. Therefore, in the transport container 1 of the first embodiment, it is possible to hook fingers on the pair of operating parts 58 from the outside of the transport container 1 to move the oscillating side wall 5 to the engaging position with the bottom wall 2, and the force operating the pair of operating parts 58 is easily transmitted to the engaging parts 520, facilitating the task of engaging the engaging parts 520 with the bottom wall 2. Therefore, the transport container 1 of the first embodiment is easy to assemble.

[0112] As in the above-described embodiment and its modified example, the transport container 1 of the second aspect has the following configuration.

[0113] That is, the transport container 1 of the second embodiment includes a bottom wall 2, a mouth frame 3 that is frame-shaped in plan view and located above the bottom wall 2, and multiple side walls 4 attached between the mouth frame 3 and the bottom wall 2.
