The outer container 2 has an outer bottom wall 20 that forms the bottom of the outer container 2, and outer side walls 21 that rise from the outer periphery of the outer bottom wall 20. The space surrounded by the outer bottom wall 20 and the outer side walls 21 is the storage space S1 that is open upward. The outer container 2 is a resin molded product in which the outer bottom wall 20 and the outer side walls 21 are integrally molded.

[0015] 2-1-1. Bottom wall of exterior The exterior bottom wall 20 has a rectangular shape in a plan view. The exterior bottom wall 20 has a flat bottom wall main body 200 that forms the upper surface of the exterior bottom wall 20, and lattice-like ribs 201 that protrude from the lower surface of the bottom wall main body 200 (see FIGS. 9A and 9B). The ribs 201 are provided on the entire lower surface of the bottom wall main body 200 except for the outer periphery.

[0016] 3 , the exterior bottom wall 20 has a rectangular shape in a plan view and has a first end side 202 and a second end side 203 that are perpendicular to each other. The first end side 202 is the end side that extends in the longitudinal direction among the four end sides of the bottom wall main body portion 200, and the second end side 203 is the end side that extends in the lateral direction among the four end sides of the bottom wall main body portion 200. A first direction D1 along the first end side 202 is the longitudinal direction of the exterior bottom wall 20, and a second direction D2 along the second end side 203 is the lateral direction of the exterior bottom wall 20.

[0017] 3, 4A and 4B, and 5A and 5B, positioning portions 5 that can engage with each other are provided on the exterior bottom wall 20 and the interior bottom wall 30 that forms the bottom of the inner container 3. In this embodiment, the positioning portions 5 are uneven.

[0018] The positioning portion 5 is provided on one of the exterior bottom wall 20 and the interior bottom wall 30 and is composed of a protrusion 6 that protrudes toward the other of the exterior bottom wall 20 and the interior bottom wall 30, and a recess 7 that is provided on the other of the exterior bottom wall 20 and the interior bottom wall 30 and into which the protrusion 6 can be inserted. The protrusion 6 has a pair of inclined side surfaces that are spaced apart so that the distance between them becomes narrower toward the tip end in the protruding direction.

[0019] 4A and 4B, a protrusion 6 is provided on the exterior bottom wall 20. A part of the protrusion 6 is provided on the upper surface of the bottom wall main body 200 of the exterior bottom wall 20 above the rib 201, as shown in FIG.

[0020] As shown in FIG. 4A, the exterior bottom wall 20 is provided with a plurality of (four in this embodiment) protrusions 6. The plurality of protrusions 6 include two first protrusions 6a and 6b spaced apart in a first direction D1 and two second protrusions 6c and 6d spaced apart in a second direction D2. The protrusions 6a, 6b, 6c, and 6d have the same shape. In this embodiment, as shown in FIG. 4B, each of the protrusions 6a, 6b, 6c, and 6d has a quadrangular pyramid shape. Each of the protrusions 6a, 6b, 6c, and 6d has a rectangular shape in a plan view. The protrusions 6a, 6b, 6c, and 6d are arranged in a cross shape in a plan view.

[0021] Each protrusion 6 has a pair of first side surfaces 60, 61 facing one of the first direction D1 and the second direction D2, a pair of second side surfaces 62, 63 facing the other, and a top surface 64. The top surface 64 is rectangular in plan view. In the two first protrusions 6a, 6b, the pair of first side surfaces 60, 61 face the second direction D2, and the pair of second side surfaces 62, 63 face the first direction D1. In the two second protrusions 6c, 6d, the pair of first side surfaces 60, 61 face the first direction D1, and the pair of second side surfaces 62, 63 face the second direction D2.

[0022] The pair of first side surfaces 60, 61 and the pair of second side surfaces 62, 63 are inclined so that the distance between them becomes narrower toward the tip end (i.e., the upper portion) in the protruding direction. At the same height, the distance between the pair of first side surfaces 60, 61 is shorter than the distance between the pair of second side surfaces 62, 63. As shown in FIG. 5B, the length between the lower ends of the pair of first side surfaces 60, 61 of each protrusion 6 is slightly shorter than the length of the recess 7 in the direction in which the pair of first side surfaces 60, 61 are aligned. As shown in FIG. 5A, the length between the lower ends of the pair of second side surfaces 62, 63 of each protrusion 6 is shorter than the length of the recess 7 in the direction in which the pair of second side surfaces 62, 63 are aligned.

[0023] 2-1-2.Exterior side wall 3, the exterior side walls 21 extend along the four edges of the exterior bottom wall 20. The exterior side walls 21 have a pair of long side wall portions 21a extending along the long edge (i.e., the first edge 202) of the exterior bottom wall 20, and a pair of short side wall portions 21b extending along the short edge (i.e., the second edge 203) of the exterior bottom wall 20. The pair of long side wall portions 21a and the pair of short side wall portions 21b are continuous to form a rectangular frame in a plan view.

[0024] Each of the pair of long side wall portions 21a and the pair of short side wall portions 21b has a rectangular, flat body portion 22 and a rib 23 that protrudes outward in the thickness direction from the body portion 22. The body portion 22 protrudes upward from a portion of the bottom wall body portion 200 that is slightly inside the outer periphery. The rib 23 is provided so that its tip in the protruding direction (i.e., outer end) is located on the outer periphery of the bottom wall body portion 200.

[0025] The ribs 23 include a plurality of horizontal ribs 24 extending in the horizontal direction and a plurality of vertical ribs 25 extending in the vertical direction and intersecting the horizontal ribs 24. Each of the horizontal ribs 24 is plate-shaped with a thickness in the up-down direction, and each of the vertical ribs 25 is plate-shaped with a thickness in the horizontal direction. In the long side wall portion 21a, the vertical ribs 25 have a thickness in the front-to-back direction, and in the short side wall portion 21b, the vertical ribs 25 have a thickness in the left-to-right direction. The lower ends of some of the vertical ribs 25 are connected to the outer periphery of the bottom wall main body portion 200 of the exterior bottom wall 20.

[0026] The exterior side wall 21 further has vertical ribs 26 that protrude outward from the corners formed by the long side wall portions 21a and the short side wall portions 21b. The exterior side wall 21 has four vertical ribs 26. The upper end of each vertical rib 26 is connected to the upper horizontal rib 24, and the lower end of each vertical rib 26 is connected to the outer periphery of the bottom wall main body portion 200 of the exterior bottom wall 20.

[0027] Next, the short side wall portion 21b will be described in more detail.

[0028] The multiple transverse ribs 24 are composed of two rows of transverse ribs 240, 241 provided at the upper end of the main body portion 22. The transverse rib 240 is provided at the upper end of the main body portion 22, and the transverse rib 241 is provided slightly below the upper end of the main body portion 22. The transverse rib 241 is positioned downward and spaced apart from the upper transverse rib 240 and is parallel to the upper transverse rib 240.

[0029] The multiple vertical ribs 25 are located toward the center of the main body 22 in the second direction D2 and include two vertical ribs 250, 251 that span across the two horizontal ribs 240, 241, and two vertical ribs 252, 253 that span across the upper horizontal rib 240 and the outer periphery of the bottom wall main body 200, outside the two vertical ribs 250, 251 in the second direction D2. The vertical ribs 252, 253 intersect with the horizontal ribs 241.

[0030] The short side wall portion 21b has a notch portion 27 that is cut downward from the upper end surface of the short side wall portion 21b and opens outward. In this embodiment, the notch portion 27 penetrates the short side wall portion 21b in the thickness direction and opens upward both to the outside and inside.

[0031] The cutout 27 is located at the center of the short side wall 21b in the second direction D2 (i.e., the left-right direction). In this embodiment, the vertical length of the cutout 27 is about one-sixth of the vertical length of the short side wall 21b.

[0032] A rectangular opening 220, as viewed in the first direction D1, is provided in the center of the upper end of the main body 22 in the second direction D2. Two vertical ribs 250, 251 protrude outward from both side edges of the opening 220 of the main body 22, and a horizontal rib 241 protrudes outward from the lower edge of the opening 220 of the main body 22. Although the portion of the main body 22 where the opening 220 is provided would normally have reduced strength against a load from inside the outer container 2, the strength is ensured because the ribs 250, 251, 241 protrude from the periphery of the opening 220 and reinforce it.

[0033] The space surrounded by the two vertical ribs 250, 251 and the one horizontal rib 241 and the opening 220 constitutes the cutout portion 27. The bottom surface of the cutout portion 27 is formed by the lower edge surface of the opening 220 of the main body portion 22 and the upper surface of the horizontal rib 241.

[0034] A protrusion 2410 that protrudes downward is provided on the underside of the horizontal rib 241, and the horizontal rib 241 and the protrusion 2410 form a handle.

[0035] The protrusion 2410 is plate-shaped and protrudes downward from the outer end of the horizontal rib 241. The protrusion 2410 is longer in the left-right direction than the notch 27. The protrusion 2410 is provided so as to span the two vertical ribs 252, 253.

[0036] The protrusion 2410 is located along the main body 22 and spaced apart from the main body 22. Two reinforcing ribs 28 are provided on the inside of the protrusion 2410, and the protrusion 2410 is connected to the main body 22 via the two reinforcing ribs 28.

[0037] The two reinforcing ribs 28 are positioned more inward in the second direction D2 than the two vertical ribs 250, 251. The space between the two reinforcing ribs 28 forms an insertion space S2 into which a user's fingers can be inserted.

[0038] 2-2.Inner packaging 1 has a container body 34 (an interior bottom wall 30 and an interior side wall 31, which will be described later) that is placed in the storage space S1 of the outer container 2, and a flange 32 that protrudes outward from the upper end of the container body 34. The inner container 3 has an internal storage space S3 that is open upward. The inner container 3 is a resin-molded product in which the interior bottom wall 30 and the interior side wall 31 are integrally molded.

[0039] 6, the inner container 3 has an inner bottom wall 30 that forms the bottom of the inner container 3, an inner side wall 31 that rises from the outer periphery of the inner bottom wall 30, and a flange 32 that protrudes outward from the upper peripheral edge of the inner side wall 31. The space surrounded by the inner bottom wall 30 and the inner side wall 31 is an inner storage space S3 that is open upward.

[0040] The interior bottom wall 30 has a rectangular shape in a plan view. As shown in Figures 6 and 7, the interior bottom wall 30 has a flat bottom wall main body 300 that forms the upper surface of the interior bottom wall 30, and lattice-like ribs 301 that protrude from the lower surface of the bottom wall main body 300. The ribs 301 are provided over the entire lower surface of the bottom wall main body 300.

[0041] The lattice-shaped ribs 301 are made up of a plurality of ribs 301a extending linearly in the first direction D1 and a plurality of ribs 301b extending linearly in the second direction D2 and intersecting with the plurality of ribs 301a. Each of the plurality of ribs 301a extends from one end to the other end of the interior bottom wall 30 in the first direction D1. Each of the plurality of ribs 301b extends from one end to the other end of the interior bottom wall 30 in the second direction D2. The lattice-shaped ribs 301 form a large number of recesses 302 that open downward.

[0042] In this embodiment, the lower surface of the interior bottom wall 30 is provided with multiple (four in this embodiment) recesses 7 into which multiple protrusions 6 provided on the upper surface of the exterior bottom wall 20 are inserted. Each recess 7 is formed by providing some of the multiple ribs 301a, 301b, among the multiple ribs 301a, 301b, discontinuously in a portion of their longitudinal direction. Each recess 7 is surrounded by two ribs 301a aligned in the first direction D1 and two ribs 301b aligned in the second direction D2, forming a rectangular recess when viewed from below. As shown in FIGS. 5A and 5B, the two ribs 301a are shorter in the second direction D2 toward their distal ends, and the two ribs 301b are shorter in the first direction D1 toward their distal ends. As shown in FIG. 7, each recess 7 is longer in both the first direction D1 and the second direction D2 than each of the multiple recesses 302 surrounding it.

[0043] As shown in Fig. 6, the interior side walls 31 extend along the four edges of the interior bottom wall 30, which is rectangular in plan view. The interior side walls 31 have a pair of long side wall portions 31a extending along the long edges of the interior bottom wall 30, and a pair of short side wall portions 31b extending along the short edges of the interior bottom wall 30. The pair of long side wall portions 31a and the pair of short side wall portions 31b are continuous in the shape of a rectangular frame in plan view. Each of the pair of long side wall portions 31a and the pair of short side wall portions 31b is flat.

[0044] In this embodiment, the flange 32 protrudes outward from the upper peripheral edge of the interior side wall 31 along the entire periphery and has a rectangular frame shape in plan view. The flange 32 has a pair of long-side flange portions 32a protruding outward in the second direction D2 (i.e., outward in the left-right direction) from the upper ends of the pair of long-side wall portions 31a, and a pair of short-side flange portions 32b protruding outward in the first direction D1 (i.e., outward in the front-rear direction) from the upper ends of the pair of short-side wall portions 31b. The pair of long-side flange portions 32a and the pair of short-side flange portions 32b are continuous to form a rectangular frame shape in plan view.

[0045] The pair of longitudinal flange portions 32a and the pair of lateral flange portions 32b are each plate-shaped with the thickness direction extending in the up-down direction. The pair of longitudinal flange portions 32a and the pair of lateral flange portions 32b are provided so as to rest on the upper end surface of the exterior side wall 21 (i.e., the upper surface of the upper end horizontal rib 240) over their entire circumferential length.

[0046] As shown in Fig. 7, a finger hook 320 is provided on the underside of the pair of short-side flanges 32b in a central portion in the second direction D2 located above the notch 27, protruding downward as a handle. In this embodiment, the finger hook 320 is provided at the tip end (i.e., the outer end) of the short-side flanges 32b in the protruding direction, and includes a rib 321 extending linearly in the second direction D2 and two ribs 322 extending linearly in the first direction D1 to connect both ends of the rib 321 in the second direction D2 to the short-side wall 31b. The distance between the two ribs 322 is slightly shorter than the length of the notch 27 in the second direction D2. When the inner container 3 is placed in the storage space S1 of the outer container 2, the two ribs 322 are positioned adjacent to the two vertical ribs 250, 251. The distance between the two ribs 322 may be longer than the length of the cutout portion 27 in the second direction D2.

[0047] In this way, the portion of the pair of short-side flanges 32b located above the notch 27 is reinforced by being thicker than the surrounding portion by providing the ribs 321, 322. Note that the portion of the pair of short-side flanges 32b located above the notch 27 may not be provided with the ribs 321, 322, and the entire portion may be thicker than the surrounding portion.

[0048] 2-3. Lid The lid 4 shown in Fig. 2 is configured to cover the inner container 3 from above. The lid 4 is a resin molded product. The lid 4 has a lid main body 40 that is arranged above the internal storage space S3 of the inner container 3, and a lid outer periphery 41 that is arranged above the protruding portion 33 of the inner container 3. As shown in Figs. 9A and 9B, the lid 4 further has a restricting portion 42 that protrudes downward from the outer periphery of the lid main body 40.

[0049] As shown in Fig. 2, the lid main body 40 has a rectangular flat plate shape in a plan view. The lid outer peripheral portion 41 extends outward from the outer peripheral edge of the lid main body 40 and has a rectangular frame shape in a plan view. In this embodiment, the lid outer peripheral portion 41 protrudes upward beyond the lid main body 40. The lid outer peripheral portion 41 is placed on the flange 32 of the inner container 3.

[0050] The lid outer peripheral portion 41 includes a pair of long-side frame portions 41a along the long-side edges of the lid main body portion 40 and a pair of short-side frame portions 41b along the short-side edges of the lid main body portion 40. In this embodiment, the lid outer peripheral portion 41 has a hollow structure. Each of the pair of long-side frame portions 41a is provided with a plurality of recesses 410 that open outward in the second direction D2. The plurality of recesses 410 are positioned side by side in the first direction D1. As shown in FIG. 9B , each of the pair of short-side frame portions 41b is provided with a plurality of recesses 411 that open downward. The plurality of recesses 411 are positioned side by side in the second direction D2.

[0051] 9A and 9B is provided around the entire outer periphery of the lid main body 40. The restricting portion 42 has a rectangular frame shape when viewed from below. The restricting portion 42 is provided to be slightly smaller than the inner side wall 31. The restricting portion 42 restricts the lid 4 from slipping off the inner container 3.

[0052] In this embodiment, the inner container 3, outer container 2, and lid 4 are configured such that the thicknesses of the plate-shaped main portions constituting each component decrease in the order of inner container 3, outer container 2, and lid 4. Specifically, the bottom wall main body portion 300, inner side wall 31, and flange 32 of the inner container 3 are thicker than the bottom wall main body portion 200 of the outer container 2 and the main body portion 22 of the outer side wall 21. The bottom wall main body portion 200 of the outer container 2 and the main body portion 22 of the outer side wall 21 are thicker than the lid main body portion 40 of the lid 4. Therefore, the inner container 3 has sufficient strength to be used alone. Furthermore, the outer container 2 is thinner than the inner container 3 but thicker than the lid 4, which facilitates weight reduction while maintaining sufficient strength to support a load. When the outer container 2 is used together with the inner container 3, the weight can be reduced.

[0053] The inner container 3, outer container 2, and lid 4 may be provided such that the thickness of the plate-like main portion constituting each part decreases in the order of outer container 2, inner container 3, and lid 4.

[0054] 3. Effects In the transportation container 1 of this embodiment described above, when the inner container 3 is placed inside the outer container 2, the protruding portion 33 (more specifically, the flange 32) of the inner container 3 is located above the bottom surface of the cutout portion 27, as shown in FIG. 6A.

[0055] Therefore, a user can remove the inner container 3 from the outer container 2 by inserting a finger from the outside of the container between the bottom surface of the notch 27 and the protruding portion 33 and lifting it up. Note that the protruding portion 33 can be lifted not only by the user's hand but also by an automatic machine.

[0056] Furthermore, in the transportation container 1 of this embodiment, part of the flange 32 at the upper end of the inner container 3 constitutes the protruding portion 33, which prevents the structure of the inner container 3 from becoming too complicated. Furthermore, it is easier to ensure the strength of the protruding portion 33 compared to when the protruding portion 33 is provided partially so as to be positioned within the cutout portion 27. Furthermore, the space between the protruding portion 33 and the bottom surface of the cutout portion 27 is longer in the vertical direction, making it easier to insert a finger into this space.

[0057] Furthermore, in the transport container 1 of this embodiment, the horizontal rib 241 that forms the bottom surface of the cutout portion 27 and the protrusion 2410 that protrudes from its underside form the handle, so that the outer container 2 can be lifted by holding the handle with the fingers in the same manner as when lifting the protrusion 33.

[0058] Therefore, with the transport container 1 of this embodiment, the operation of removing the inner container 3 from the outer container 2 and the operation of lifting the outer container 2 can be performed by substantially the same action.

[0059] Furthermore, in the transport container 1 of this embodiment, finger hook 320 is provided at the portion of flange 32 where fingers are hooked, making it easy to hook fingers and lift, and also improving strength.

[0060] Furthermore, in the transport container 1 of this embodiment, the horizontal ribs 241 and the protrusions 2410 are integrated with the main body 22 of the exterior side wall 21 via the reinforcing ribs 28, which improves the strength of the handle.

[0061] Furthermore, in the transport container 1 of this embodiment, when the inner container 3 is placed inside the outer container 2, the four protrusions 6 protruding upward from the outer bottom wall 20 can be inserted into the four recesses 7 on the underside of the inner bottom wall 30. At this time, the pair of first side surfaces 60, 61 and the pair of second side surfaces 62, 63 of each of the four protrusions 6 act as guides, making it easy to place the inner container 3 in an appropriate location inside the outer container 2.

[0062] Furthermore, in the transport container 1 of this embodiment, when the interior bottom wall 30 is shifted in the first direction D1 or the second direction D2 from a state in which the four convex portions 6 of the exterior bottom wall 20 are inserted into the four concave portions 7 of the interior bottom wall 30, the convex portions 6 engage with the concave portions 7, making it easy to prevent horizontal positional shifting of the inner container 3. This makes it easy to hold the inner container 3 in an appropriate position within the exterior container 2 and to position the protrusion 33 (flange 32) above the bottom surface of the cutout portion 27.

[0063] 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.

[0064] The inner container 3 is not limited to the structure shown in Fig. 6. The protruding portion 33 need only protrude upward from the bottom surface of the cutout portion 27 to a position spaced apart, and does not have to be constituted by a part of the flange 32. The protruding portion 33 may protrude into the cutout portion 27 from a portion below the upper end of the container body portion 34. In this case, the inner container 3 does not need to have a flange 32.

[0065] 10, the protruding portion 33 may be provided so that its tip in the protruding direction is located more inward than the notch 27. In this modification, the protruding portion 33 protrudes from a portion below the upper end of the container main body 34 (more specifically, the short side wall portion 31b of the interior side wall 31) toward the notch 27. The protruding portion 33 protrudes from a portion of the short side wall portion 31b in the second direction D2. Even in this modification, the inner container 3 can be removed by inserting a finger from the outside of the side of the notch 27 and lifting the protruding portion 33.

[0066] Furthermore, the cutout 27 may be provided so as to open only to the outside and not to open to the inside. In other words, the cutout 27 does not have to penetrate the short side wall 21b in the thickness direction, and may open only to the outside.

[0067] Furthermore, the short side wall portion 21b of the exterior side wall 21 may not have the rib 23, and may be a flat plate formed only by the main body portion 22. In this case, the opening 220 provided in the main body portion 22 forms the notch portion 27.

[0068] Furthermore, the flange 32 does not necessarily have to include the pair of long-side flange portions 32a, and may be configured with only the pair of short-side flange portions 32b.

[0069] Furthermore, the inner container 3 is not limited to a rectangular box shape, and may be other shapes such as a bowl shape. The inner container 3 may also be provided in the shape of a tray, and may be shorter in the vertical direction than the outer container 2. In this case, the inner bottom wall 30 does not need to be provided with a positioning portion 5 (i.e., a recess 7).

[0070] Furthermore, the vertical ribs 250, 251 of the outer container 2 may be inclined so that the lower portions thereof are positioned more inward in the second direction D2 (i.e., closer to the cutout 27). At least one of the outer surfaces of the short side wall portions 31b and the underside of the short side flange portions 32b of the inner container 3 may be provided around the finger hook portion 320 with ribs that come into contact with the vertical ribs 250, 251 when the inner container 3 is inserted into the outer container 2 with a misalignment in the second direction D2. In this case, when the inner container 3 is inserted into the outer container 2, the ribs come into contact with the vertical ribs 250, 251, thereby guiding the inner container 3 to an appropriate position within the outer container 2. Note that the outer container 2 may be provided with a pair of inclined vertical ribs 250, 251 in four directions (i.e., on both the pair of long side wall portions 21a and the pair of short side wall portions 21b), and similarly, the inner container 3 may be provided with ribs that are guided by the vertical ribs 250, 251 in four directions. In this case, when inserting the inner container 3 into the outer container 2, even if the inner container 3 shifts in either the first direction D1 or the second direction D2, the inner container 3 can be guided to an appropriate position within the outer container 2.

[0071] Furthermore, the notch portions 27 are not limited to being provided only in the pair of short side wall portions 21b, but may be provided only in the pair of long side wall portions 21a, or may be provided in both the pair of short side wall portions 21b and the pair of long side wall portions 21a.

[0072] Furthermore, the inner container 3 may have reinforcing ribs on the outer surface of the inner side wall 31 and at the corners formed by the inner side wall 31 and the flange 32 .

[0073] Furthermore, the outer container 2 does not necessarily have to have the horizontal rib 241 and the protrusion 2410 that form the handle. For example, in the main body 22 of the short side wall 21b of the outer container 2, a rib may be provided at the lower edge of the notch 27 that protrudes outward shorter than the rib 23 and extends longer in the second direction D2.

[0074] The outer container 2 may also be provided with a handle formed of an opening penetrating the short side wall portion 21b in the thickness direction. The horizontal rib 241 is not limited to being located immediately below and adjacent to the cutout portion 27, but may be located away from the cutout portion 27 and below, or may be located at a position offset in the second direction D2 from the cutout portion 27.

[0075] Furthermore, the transport container 1 does not need to be provided with the lid 4 and may be composed of only the outer container 2 and the inner container 3.

[0076] Furthermore, the exterior bottom wall 20 and the interior bottom wall 30 do not necessarily have to be provided with recesses and projections (i.e., positioning portions 5) that can engage with each other. Furthermore, the positioning portions 5 provided on the exterior bottom wall 20 and the interior bottom wall 30 are not limited to the structure shown in Figures 5A and 5B. For example, a recess 7 may be provided on the upper surface of the exterior bottom wall 20, and a protrusion 6 may be provided on the lower surface of the interior bottom wall 30.

[0077] The shape of the protrusion 6 is not limited to the truncated quadrangular pyramid shape shown in Fig. 4B, and may be other shapes. For example, the protrusion 6 may be provided with a recess that divides the protrusion 6 into two parts in the first direction D1 or the second direction D2. Furthermore, the protrusion 6 may be provided with a notch that opens upward and on one side in the first direction D1 or one side in the second direction D2 so as to form a U-shape in plan view.

[0078] Moreover, the interior bottom wall 30 does not necessarily have to be provided with the rib 301, and the recess 7 may be provided by recessing a part of the lower surface of the bottom wall main body 300.

[0079] Furthermore, the protrusions 2410 protruding from the lower surfaces of the horizontal ribs 241 are not limited to being plate-shaped, and may be short in the vertical direction.

[0080] Furthermore, the outer container 2 is not limited to a resin molded product in which the outer bottom wall 20 and the outer side wall 21 are integrally molded, but may also be an assembled container formed by assembling the outer bottom wall 20 and the outer side wall 21, or may be a foldable container.

[0081] The two vertical ribs 250, 251 may be provided so as to bridge the upper horizontal rib 240 and the outer periphery of the bottom wall main body portion 200. In this case, the strength of the outer container 2 against a load from above can be improved.

[0082] The plurality of longitudinal ribs 25 may further include at least one longitudinal rib provided below the notch 27.

[0083] Furthermore, the inner container 3 may be provided with a reinforcing rib on at least one of the outer surface of the inner side wall 31, the lower surface of the flange 32, and the corner portion formed by the outer surface of the inner side wall 31 and the lower surface of the flange 32.

[0084] 9A and 9B, in this embodiment, the inner surface of the corner formed by the exterior bottom wall 20 of the exterior container 2 and the main body 22 of the exterior side wall 21 is a curved surface that is curved in an arc shape, but it may also be provided as an obliquely inclined surface (i.e., a C-surface). In this case, the lattice-like ribs 301 provided on the interior bottom wall 30 of the inner container 3 may be provided such that the ribs 301a, 301b located at the outermost periphery are shorter in the vertical direction than the ribs 301a, 301b located further inward.

[0085] (summary) As in the embodiment and its modified example described above, the transport container 1 of the first aspect has the following configuration.

[0086] That is, the transport container 1 of the first embodiment comprises an outer container 2 having an internal storage space S1 that is open upward, and an inner container 3 that is placed in the storage space S1. The outer container 2 has a cutout portion 27 that is cut downward from the upper end surface of the outer container 2 and opens outward. The inner container 3 has a protrusion 33 that protrudes upward from the bottom surface of the cutout portion 27 at a distance.

[0087] In the transport container 1 of the first embodiment having the above configuration, the inner container 3 can be removed by inserting a finger from the outside between the bottom surface of the cutout portion 27 and the protruding portion 33 of the inner container 3 and lifting the protruding portion 33, making it easy to remove the inner container 3 from the outer container 2.

[0088] 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.

[0089] That is, in the transportation container 1 of the second embodiment, the inner container 3 has a container body 34 placed in the storage space S1 and a flange 32 protruding outward from the upper end of the container body 34. A part of the flange 32 forms a protruding portion 33.

[0090] In the transport container 1 of the second embodiment having the above configuration, part of the flange 32 that the inner container 3 has at the upper end can be used as the protruding portion 33, thereby preventing the structure of the inner container 3 from becoming too complicated. Furthermore, in the transport container 1 of the second embodiment, it is easier to ensure the strength of the protruding portion 33 compared to when the protruding portion 33 is provided partially so as to be located only within the cutout portion 27.

[0091] As in the modified example of the embodiment described above, the transport container 1 of the third aspect additionally comprises the following features in addition to the features of the first aspect.

[0092] That is, in the transport container 1 of the third embodiment, the protruding portion 33 is provided so that the tip in the protruding direction is located inside the notch portion 27 .

[0093] In the transportation container 1 of the third embodiment having the above-described configuration, the inner container 3 can be removed by inserting a finger further inside than the notch 27 and lifting the protruding portion 33.

[0094] Furthermore, like the embodiment and its modified example described above, the transport container 1 of the fourth aspect additionally has the following configuration in addition to the configuration of any one of the first to third aspects.

[0095] That is, in the transport container 1 of the fourth embodiment, the outer container 2 has a plate-like horizontal rib 241 that protrudes outward below the cutout 27 and has a thickness in the vertical direction. The upper surface of the horizontal rib 241 forms the bottom surface of the cutout 27, and a protrusion 2410 that protrudes downward is provided on the lower surface of the horizontal rib 241. The horizontal rib 241 and the protrusion 2410 form a handle.

[0096] In the transport container 1 of the fourth embodiment having the above configuration, a handle (horizontal rib 241 and protrusion 2410) is located adjacent to and directly below the cutout 27. Therefore, in the transport container 1 of the fourth embodiment, the action of removing the inner container 3 from the outer container 2 and the action of lifting the outer container 2 can be performed in substantially the same action. Furthermore, in the transport container 1 of the fourth embodiment, the protrusion 2410 protrudes downward from the underside of the horizontal rib 241, making it easy to hook a finger on the protrusion 2410 and to lift the outer container 2.

[0097] Furthermore, like the embodiment and its modified example described above, the transport container 1 of the fifth aspect additionally has the following configuration in addition to the configuration of any one of the first to fourth aspects.

[0098] That is, the transportation container 1 of the fifth embodiment further comprises a lid 4 that covers the inner container 3 from above. The lid 4 has a lid outer periphery 41 located above the protrusion 33.

[0099] In the fifth aspect of the transport container 1 having the above configuration, when lifting the protruding portion 33 to remove the inner container 3 from the outer container 2, the outer lid peripheral portion 41 of the lid 4 can be easily grasped, making it easy to remove the inner container 3 and the lid 4 from the outer container 2.

[0100] Furthermore, like the embodiment and its modified example described above, the transport container 1 of the sixth aspect additionally has the following configuration in addition to the configuration of any one of the first to fifth aspects.

[0101] That is, in the transport container 1 of the sixth embodiment, the outer container 2 has an outer bottom wall 20 that forms the bottom of the outer container 2. The inner container 3 has an inner bottom wall 30 that forms the bottom of the inner container 3. The outer bottom wall 20 and the inner bottom wall 30 are provided with projections and recesses that can engage with each other.

[0102] In the transport container 1 of the sixth aspect having the above configuration, when placing the inner container 3 inside the outer container 2, the unevenness acts as a guide, making it easy to place the inner container 3 in an appropriate position inside the outer container 2. Furthermore, in the transport container 1 of the sixth aspect, when the inner container 3 tries to shift position after being placed inside the outer container 2, the unevenness engages with each other, making it easy to prevent the inner container 3 from shifting position. Therefore, in the transport container 1 of the sixth aspect, it is easy to position the protrusion 33 of the inner container 3 above the bottom surface of the cutout portion 27 of the outer container 2, making it easy to remove the inner container 3 from the outer container 2.

[0103] 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.
