The outer container 2 has a cutout portion 27 that is cut downward from the top 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 to a position spaced apart from the bottom surface. The lid 4 has a lid outer periphery 41 located above the protrusion 33, and a cover portion 43 that extends downward from the lid outer periphery 41 and covers the protrusion 33 from the outside.

[0011] In one embodiment of the transport container 1 having the above configuration, with the lid 4 removed, the inner container 3 can be removed by inserting a finger from the outside side 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. In addition, in one embodiment of the transport container 1, with the lid 4 attached, the protruding portion 33 can be covered from the outside by the covering portion 43 of the lid 4, making it possible to prevent the protruding portion 33 from being accidentally lifted when lifting the outer container 2.

[0012] 2.Details Next, the transport container 1 of this embodiment shown in Figures 1 to 10 will be described in more detail with reference to the drawings. As shown in Figures 1 and 2, the transport container 1 of this embodiment comprises an outer container 2 having an upwardly open storage space S1 therein, an inner container 3 placed in the storage space S1, and a lid 4 that covers the inner container 3 from above. In this embodiment, the transport container 1 is a box that is rectangular in plan view.

[0013] In the following, each configuration will be described, with the longitudinal direction of the transport container 1 in a planar view being the front-to-back direction or first direction D1, the short side direction of the transport container 1 in a planar view being the left-to-right direction or second direction D2, and the height direction of the transport container 1 being the up-to-down direction.

[0014] 2-1. Outer packaging As shown in Fig. 3, the outer container 2 has an internal storage space S1 that is open upward. 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] In this embodiment, the upper horizontal rib 240 is shorter in the first direction D1 than the horizontal rib 241 below it. The vertical ribs 250, 251 and the portion between two of the vertical ribs 252, 253, the horizontal ribs 240, 241, are shorter in the first direction D1 than the horizontal rib 241. As a result, a storage portion S4 is formed in the portion of the short side wall portion 21b above the horizontal rib 241, which is recessed inward to accommodate a peripheral wall portion 44 of the lid 4, which will be described later. A similar storage portion S4 is also formed on the outside of the upper end of the long side wall portion 21a.

[0039] 2-2.Inner packaging 2 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] 2-3. Lid The lid 4 shown in FIG. 1 is configured to cover the inner container 3 and the outer container 2 from above. The lid 4 is a resin molded product. The lid 4 has a lid main body 40 arranged above the internal storage space S3 of the inner container 3, and a lid outer peripheral portion 41 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 protruding downward from the outer peripheral portion of the lid main body 40. The lid 4 further has a covering portion 43 protruding downward from the lid outer peripheral portion 41 and covering the protruding portion 33 from the outside. In this embodiment, the lid 4 has a peripheral wall portion 44 extending downward from the outer peripheral edge of the lid outer peripheral portion 41. A part of the peripheral wall portion 44 is the covering portion 43.

[0050] As shown in Fig. 1, 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. It is also possible to place the lid outer peripheral portion 41 directly on the upper flange of the outer container 2 (i.e., the upper horizontal rib 24).

[0051] 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. As shown in FIG. 9B , each of the pair of short-side frame portions 41b is provided with a plurality of downwardly opening recesses 411. The plurality of recesses 411 are positioned side by side in the second direction D2. Similarly, each of the pair of long-side frame portions 41a is provided with a plurality of downwardly opening recesses 411. The plurality of recesses 411 are positioned side by side in the first direction D1.

[0052] The restricting portion 42 shown in Figures 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 is also provided to be slightly smaller than the outer side wall 21. The restricting portion 42 restricts the lid 4 from slipping off from the inner container 3. When the lid 4 is placed directly on the outer container 2, the restricting portion 42 restricts the lid 4 from slipping off from the outer container 2.

[0053] The peripheral wall portion 44 extends downward from the entire circumferential length of the outer peripheral edge of the lid outer periphery 41. As shown in FIG. 1 , the peripheral wall portion 44 includes a pair of long side wall portions 44a extending downward from the pair of long side frame portions 41a, and a pair of short side wall portions 44b extending downward from the pair of short side frame portions 41b. The pair of long side wall portions 44a and the pair of short side wall portions 44b are continuous to form a rectangular frame in plan view. The central portion of each of the pair of short side wall portions 44b in the second direction D2 (i.e., the portion located outside the cutout portion 27) forms the cover portion 43.

[0054] 1 and 2, each of the pair of short side walls 44b of the peripheral wall 44 of the lid 4 is provided with a length that covers from the outside a portion of the short side wall 21b of the outer container 2 that is above the horizontal rib 241. Each of the pair of long side walls 44a is provided with a length that covers from the outside a portion of the long side wall 21a of the outer container 2 that is above the second-from-the-top horizontal rib 24. The pair of short side walls 44b and the pair of long side walls 44a have the same vertical length.

[0055] 9A and 9B, when the lid outer peripheral portion 41 of the lid 4 is placed on the flange 32 of the inner container 3, a small gap is formed between the lower ends of the pair of short side wall portions 44b and the horizontal rib 24 below it (i.e., the horizontal rib 241). Similarly, a small gap is formed between the lower ends of the pair of long side wall portions 44a and the horizontal rib 24 below it (i.e., the second horizontal rib 24 from the top). The small gap here refers to a gap that is too small for a user's fingers to be inserted. Note that even when the lid 4 is placed directly on the flange at the upper end of the outer container 2, a small gap is formed between the lower ends of the walls 44a and 44b of the lid 4 and the horizontal rib 24 below them.

[0056] In this way, minute gaps are formed between the lower ends of the wall portions 44a, 44b of the lid 4 and the horizontal ribs 24 below them, so that when a downward load is applied to the lid 4, contact between the lower ends of the wall portions 44a, 44b of the lid 4 and the horizontal ribs 24 below them can be avoided. Therefore, in the transport container 1 of this embodiment, the wall portions 44a, 44b and the horizontal ribs 24 below them are less likely to be damaged by contact. In addition, because minute gaps are formed between the wall portions 44a, 44b of the lid 4 and the horizontal ribs 24 below them, it is easy to hook fingers on the lower ends of the wall portions 44a, 44b, making it easy to lift the lid 4.

[0057] In addition, the pair of long side wall portions 44a and the pair of short side wall portions 44b may be arranged so as to contact the horizontal rib 24 below the lid outer periphery 41 of the lid 4 when it is placed on the flange 32 of the inner container 3.

[0058] The short side wall portion 44b (that is, the cover portion 43) protrudes slightly inclined relative to the vertical direction so that the lower portion is positioned further outward from the outer peripheral edge of the lid outer peripheral portion 41.

[0059] When the lid outer peripheral portion 41 of the lid 4 is placed on the flange 32 of the inner container 3, the cover portion 43 is located outside the notch 27. When the lid 4 is placed on the outer container 2 and the inner container 3 so that the center of the lid 4 in a plan view is located directly above the center portions of the outer container 2 and the inner container 3 in a plan view, the outer edge of the lid 4 in the first direction D1, i.e., the outer edge of the short side wall portion 44b (in this embodiment, the lower end of the outer surface of the short side wall portion 44b), is located at the same level as or more inward than the tips of the horizontal ribs 241 in the first direction D1. In other words, in the above state, the outer edge of the lid 4 in the first direction D1 (i.e., the lower end of the outer surface of the short side wall portion 44b) is located directly above or more inward than the tips of the horizontal ribs 241. The protrusions 2410 of the handle are located inside the outer edge of the outer container 2 (the tips of the horizontal ribs 241 in FIG. 9A ).

[0060] Similarly, the longitudinal side wall portions 44a protrude slightly inclined relative to the vertical direction so that the lower portions are positioned further outward from the outer periphery of the lid outer periphery 41.

[0061] When the lid 4 is placed on the outer container 2 and the inner container 3 so that the center of the lid 4 in a plan view is located directly above the center of the outer container 2 and the inner container 3 in a plan view, the outer edge of the lid 4 in the second direction D2, i.e., the outer edge of the longitudinal side wall 44a (in this embodiment, the lower end of the outer surface of the longitudinal side wall 44a) is located at the same level as or more inward than the tip of the underlying horizontal rib 24 in the second direction D2. In other words, in the above state, the outer edge of the lid 4 in the second direction D2 (i.e., the lower end of the outer surface of the longitudinal side wall 44a) is located directly above or more inward than the tip of the underlying horizontal rib 24.

[0062] As described above, in the transport container 1 of this embodiment, the outer peripheral edge of the lid 4 (i.e., the lower end of the outer surface of the wall portions 44a, 44b) is located directly above or inside the outer peripheral edge of the outer container 2 (i.e., the tips of the horizontal ribs 24 below the wall portions 44a, 44b). Therefore, when two transport containers 1 are lined up in the first direction D1 or the second direction D2, it is possible to prevent the outer containers 2 from butting against each other and creating dead space between the outer containers 2, and also to prevent one transport container 1 from getting caught on the lid 4 of the other transport container 1 and being lifted up.

[0063] Furthermore, in the transport container 1 of this embodiment, the outer peripheral edge of the lid 4 does not easily protrude outward beyond the outer peripheral edge of the outer container 2, making it easy to hold the short side wall portion 44b of the lid 4 with the palm of the hand while hooking the fingers on the protrusion 2410 of the handle, making it easy to carry the transport container 1 with the lid 4. Here, if the outer peripheral edge of the lid 4 protrudes outward beyond the outer peripheral edge of the outer container 2, the palm of the hand is likely to hurt when lifting the transport container 1, starting from the part where the palm hits the outer peripheral edge of the lid 4. However, in the transport container 1 of this embodiment, the outer peripheral edge of the lid 4 does not protrude outward beyond the outer peripheral edge of the outer container 2, so the palm is less likely to hurt when lifting the transport container 1.

[0064] In this embodiment, with the lid outer peripheral portion 41 of the lid 4 placed on the flange 32 of the inner container 3 inside the outer container 2, the positional relationship in the first direction D1 between the outer container 2, the inner container 3, and the lid 4 preferably satisfies the following relationship:

[0065] 10, the distance in the first direction D1 between the short-side wall portion 21b of the outer container 2 and the short-side wall portion 31b of the inner container 3 is defined as distance L1, the distance in the first direction D1 between the short-side flange portion 32b of the inner container 3 and the short-side wall portion 44b of the lid 4 is defined as distance L2, the distance in the first direction D1 between the short-side wall portion 31b of the inner container 3 and the restricting portion 42 of the lid 4 is defined as distance L4, and the distance in the first direction D1 between the first side surfaces 60, 61 of the second protrusions 6c, 6d of the outer container 2 and the side surface of the rib 301b of the corresponding recess 7 of the inner container 3 is defined as distance L3. Furthermore, the relationship between the distances L2 to L4 may be L4 > L1 > L2 > L3. It is also preferable that the positional relationship in the second direction D2 between the outer container 2, the inner container 3, and the lid 4 is similar to that described above.

[0066] As shown in FIG. 10 , when the thickness (i.e., the vertical length) of the flange 240 of the outer container 2 is defined as thickness L5 (see FIG. 9B ), the vertical length of the short-side side wall 44b is defined as length L6, the vertical distance between the short-side side wall 44b and the horizontal rib 241 is defined as distance L7, and the vertical length of the handle protrusion 2410 is defined as length L8, it is preferable that length L8 > distance L7 ≥ thickness L5. It is also preferable that length L8 ≥ length L6 > thickness L5. It is also preferable that length L6 ≥ distance L7. When distance L7 ≥ thickness L5, it is easy to insert a finger between the short-side side wall 44b and the horizontal rib 241 and hook the finger on the lower end of the short-side side wall 44b to lift the lid 4. When length L8 ≥ length L6, the insertion space S2 inside the protrusion 2410 tends to be deep, making it easy for a finger to get caught on the protrusion 2410 when lifting the transport container 1. When length L6≧distance L7, the vertical length of the short side wall portion 44b of the lid 4 can be easily increased, so that even if the lid 4 bounces up when the transport container 1 is transported, the lid 4 is less likely to come off the outer container 2.

[0067] 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 and peripheral wall portion 44 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.

[0068] 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.

[0069] 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. 9A.

[0070] Therefore, a user can remove the lid 4 and insert their fingers from outside the container between the bottom surface of the notch 27 and the protruding portion 33 to lift the inner container 3 from the outer container 2. Note that the protruding portion 33 can be lifted not only by the user's hand but also by an automatic machine.

[0071] Furthermore, with the transport container 1 of this embodiment, when the lid 4 is attached, the protrusion 33 and the cutout 27 can be covered from the outside by the covering portion 43. Therefore, with the transport container 1 of this embodiment, when the lid 4 is attached, it is not possible to lift the container by inserting a finger from outside the container between the bottom surface of the cutout 27 and the protrusion 33, and this makes it possible to prevent the protrusion 33 from being accidentally lifted when lifting the outer container 2.

[0072] 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 complicated. Furthermore, it is easier to ensure the strength of the protruding portion 33 compared to when the protruding portion 33 is partially provided 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.

[0073] 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.

[0074] Furthermore, in the transport container 1 of this embodiment, a portion of the peripheral wall 44 of the lid 4 can be used as the cover 43, which prevents the structure of the lid 4 from becoming too complicated. Furthermore, in the transport container 1 of this embodiment, the strength of the cover 43 can be more easily ensured than when the cover 43 is provided partially to cover only the protrusion 33 from the outside, that is, only on a portion of the circumferential direction of the lid outer periphery 41.

[0075] Furthermore, in the transport container 1 of this embodiment, the peripheral wall portion 44 of the lid 4 can be accommodated in a recessed storage section S4 provided at the upper end of the outer side wall 21 of the outer container 2, thereby preventing the peripheral wall portion 44 from protruding outward more than the outer container 2.

[0076] Furthermore, in the transport container 1 of this embodiment, the lid 4 is provided with a restricting portion 42, which prevents the lid 4 from slipping off from above the flange 32 of the inner container 3, and makes it easier to maintain the covering portion 43 covering the protruding portion 33 from the outside.

[0077] Furthermore, in the transport container 1 of this embodiment, the outer side wall 21 of the outer container 2 has a cutout portion 27, which reduces the strength against loads from inside the outer container 2, but by covering it with a lid 4, deformation of the outer container 2 can be suppressed.

[0078] 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.

[0079] 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.

[0080] 11, 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.

[0081] 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 pairs of vertical ribs 250, 251 inclined toward the cutout 27 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.

[0082] 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.

[0083] 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 .

[0084] 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.

[0085] 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.

[0086] 1 and 9A and 9B. For example, the lid 4 may have a covering portion 43 protruding downward from a circumferential portion of the lid outer peripheral portion 41 (a portion located above the notch portion 27). The lid 4 may have a peripheral wall portion 44 that extends downward from the outer peripheral edge of the lid outer peripheral portion 41 and has a length that does not cover the notch portion 27, and the covering portion 43 may protrude downward from a circumferential portion of this peripheral wall portion 44.

[0087] In this case, the cover portion 43 does not have to be located outside the cutout portion 27. When the protrusion 33 is short, that is, when the tip of the protrusion 33 is located inside the cutout portion 27, the cover portion 43 may be located inside the cutout portion 27. Also, when the tip of the protrusion 33 is located inside the cutout portion 27, the cover portion 43 may be located inside the cutout portion 27.

[0088] 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 notch portion 27, but may also be located below and away from the notch portion 27.

[0089] Furthermore, the exterior bottom wall 20 and the interior bottom wall 30 do not necessarily need to be provided with projections and recesses (that is, positioning portions 5) that can engage with each other.

[0090] 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.

[0091] 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.

[0092] The plurality of longitudinal ribs 25 may further include at least one longitudinal rib provided below the notch 27.

[0093] 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.

[0094] 9A and 9B, the inner surface of the corner formed by the exterior bottom wall 20 of the outer container 2 and the main body 22 of the exterior side wall 21 is a curved surface curved in an arc shape, but it may also be provided as an obliquely inclined surface (i.e., C-face). 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.

[0095] Furthermore, the height of the horizontal rib 241 of the outer container 2 does not have to be constant over the entire length in the second direction D2. The portion of the horizontal rib 241 that is more inward in the second direction D2 than the two vertical ribs 252, 253 (i.e., the longitudinal center portion of the horizontal rib 241) may be positioned higher than the portion of the horizontal rib 241 that is more outward in the second direction D2 than the two vertical ribs 252, 253 (i.e., both longitudinal end portions of the horizontal rib 241). In this case, the short side wall portion 44b of the lid 4 may have a notch (not shown) cut out upward in a portion facing the longitudinal center portion of the horizontal rib 241. The notch is provided longer on both sides in the second direction D2 than the longitudinal center portion of the horizontal rib 241; that is, it is provided longer in the second direction D2 than the protrusion 2410 of the handle. Furthermore, the entire or at least a portion of the long side wall portion 44a in the longitudinal direction is longer downward than the short side wall portion 44b.

[0096] In this modified example, the configuration as described above allows the portion of the outer surface of the short side wall 21b below the protrusion 2410 of the horizontal rib 241 to be wider in the vertical direction, making it easier to ensure a wider area for attaching a label in the vertical direction. Furthermore, the short side wall 44b of the lid 4 has a notch, which makes it easier to avoid contact between the short side wall 44b of the lid 4 and the longitudinal center of the horizontal rib 241. It is also easy to hook a finger on the edge of the notch in the short side wall 44b of the lid 4, making it easy to lift up the lid 4 alone. Furthermore, because the long side wall 44a has a portion that is longer downward than the short side wall 44b, the lid 4 is less likely to come off the outer container 2 even if the lid 4 bounces up during transport of the transport container 1.

[0097] The lid 4 may be formed so that even when the central portion of the lid 4 in a plan view is offset from directly above the central portions of the outer container 2 and the inner container 3 in a plan view, the outer peripheral edge of the lid 4 is positioned directly above or inside the outer peripheral edge of the outer container 2.

[0098] (summary) As in the embodiment and its modified example described above, the transport container 1 of the first aspect has the following configuration.

[0099] 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, an inner container 3 that is placed in the storage space S1, and a lid 4 that covers the inner container 3 from above. 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 to a position spaced apart from the bottom. The lid 4 has a lid outer periphery 41 located above the protrusion 33, and a cover portion 43 that extends downward from the lid outer periphery 41 and covers the protrusion 33 from the outside.

[0100] In the transport container 1 of the first embodiment having the above configuration, with the lid 4 removed, 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. In addition, in the transport container 1 of the first embodiment, with the lid 4 attached, the protruding portion 33 can be covered from the outside by the covering portion 43 of the lid 4, making it possible to prevent the protruding portion 33 from being accidentally lifted when lifting the outer container 2.

[0101] 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.

[0102] That is, in the transport container 1 of the second embodiment, the cover portion 43 is located outside the notch portion 27 .

[0103] In the second embodiment of the transport container 1 having the above configuration, when the lid 4 is attached, the cover portion 43 of the lid 4 can cover the cutout portion 27 from the outside, thereby preventing fingers from entering the cutout portion 27.

[0104] As in the embodiment and its modification described above, the transport container 1 of the third aspect additionally comprises the following features in addition to the features of the first or second aspect.

[0105] That is, in the transport container 1 of the third embodiment, the lid 4 has a peripheral wall portion 44 extending downward from the outer peripheral edge of the lid outer peripheral portion 41. A part of the peripheral wall portion 44 is the cover portion 43.

[0106] In the transport container 1 of the third embodiment having the above-described configuration, a portion of the peripheral wall 44 of the lid 4 can be used as the cover 43, thereby preventing the structure of the lid 4 from becoming too complicated. Furthermore, in the transport container 1 of the third embodiment, it is easier to ensure the strength of the cover 43 compared to when the cover 43 is provided partially so as to cover only the protrusion 33 from the outside.

[0107] 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.

[0108] That is, in the transportation container 1 of the fourth 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.

[0109] In the transport container 1 of the fourth 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 fourth 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.

[0110] As in the modified example of the embodiment described above, the transport container 1 of the fifth aspect additionally comprises the following features in addition to the features of the first aspect.

[0111] That is, in the transportation container 1 of the fifth embodiment, the protruding portion 33 is provided so that the tip in the protruding direction is located inside the notch portion 27 .

[0112] In the transportation container 1 of the fifth aspect having the above-mentioned configuration, the inner container 3 can be removed by inserting a finger further inside than the notch 27 and lifting the protruding portion 33.

[0113] As in the above-described embodiment and its modified example, the transport container 1 of the sixth aspect has the following configuration.

[0114] That is, the transport container 1 of the sixth embodiment comprises an outer container 2 having an internal storage space S1 that is open upward, and a lid 4 that covers the storage space S1 from above. The lid 4 has a main body portion (lid main body portion 40 and lid outer peripheral portion 41) that covers the outer container 2 from above, and a peripheral wall portion 44 that covers the upper end of the outer container 2 from the side. The outer container 2 has ribs (horizontal rib 241, the second horizontal rib from the top, etc.) that protrude outward below the peripheral wall portion 44 and whose tips in the protruding direction form the outer peripheral edge of the outer container 2. The outer peripheral edge of the peripheral wall portion 44 is located directly above or inside the tips of the ribs.

[0115] In the transport container 1 of the sixth embodiment having the above configuration, when two transport containers 1 of the same shape are arranged side by side, the tips of the ribs of the two outer containers 2 can be arranged to butt against each other, thereby preventing dead space from occurring between the two outer containers 2. Furthermore, in the transport container 1 of the sixth embodiment, the outer peripheral edge of the peripheral wall portion 44 of the lid 4 of each of the two transport containers 1 is located directly above or inside the tips of the ribs of the outer container 2, preventing one transport container 1 from being caught on the lid 4 of the other transport container 1 when it is lifted. Therefore, the transport container 1 of the sixth embodiment makes it easy to reduce the arrangement space when multiple transport containers 1 with lids 4 are arranged side by side, and when lifting one of multiple transport containers 1 arranged side by side, the adjacent transport containers 1 are less likely to get in the way.

[0116] As in the embodiment and its modification described above, the transport container 1 of the seventh aspect additionally comprises the following features in addition to the features of the sixth aspect.

[0117] That is, in the transport container 1 of the seventh embodiment, the ribs include horizontal ribs (horizontal rib 241 and the second horizontal rib 24 from the top) extending horizontally along the outer surface of the outer container 2. The horizontal ribs are positioned downward and spaced apart from the peripheral wall portion 44 of the lid 4.

[0118] In the seventh embodiment of the transport container 1 having the above-described configuration, when a downward load is applied to the lid 4, the peripheral wall portion 44 of the lid 4 can be prevented from contacting the horizontal ribs below it, so that the peripheral wall portion 44 and the horizontal ribs 241, 24 below it are less likely to be damaged by contact.

[0119] As in the embodiment and its modification described above, the transport container 1 of the eighth aspect additionally includes the following configuration in addition to the configuration of the seventh aspect.

[0120] That is, in the transport container 1 of the eighth embodiment, the outer container 2 has a protrusion 2410 that extends downward from the tip of the horizontal rib and can be used to hook a finger.

[0121] In the eighth aspect of the transport container 1 having the above configuration, when hooking a finger on the protrusion 2410 to lift the outer container 2 and lid 4, it is easy to place the palm of the hand on the peripheral wall portion 44 of the lid 4, making it easy to carry the transport container 1 while holding down the lid 4.

[0122] As in the modified example of the embodiment described above, the transport container 1 of the ninth aspect additionally comprises the following configuration in addition to the configuration of the eighth aspect.

[0123] That is, in the transportation container 1 of the ninth embodiment, the protrusion 2410 is provided at the center portion in the longitudinal direction of the transverse rib, which is located above both end portions in the longitudinal direction of the transverse rib.

[0124] In the transport container 1 of the ninth aspect having the above configuration, it is easy to provide a long vertical length below the central portion of the horizontal rib on the outer surface of the outer container 2. Therefore, in the transport container 1 of the ninth aspect, the portion of the outer surface of the outer container 2 below the protrusion 2410 can be easily used as an attachment portion for a label that displays information about the items stored in the storage space S1.
