Mode for Carrying Out the Invention

[0009] (Embodiment 1) 1. Outline The transport container 1 with a lid according to Embodiment 1 shown in Figure 1 (hereinafter simply referred to as "container 1") includes a box-shaped container body 2 having an opening 20 on the upper surface, and a lid 3 rotatably connected to the container body 2 so as to open and close the opening 20. The upper surface of the lid 3 has a recess 4. The bottom surface 40 of the recess 4 slopes downward toward the outer peripheral edge of the lid 3.

[0010] In the container 1 of Embodiment 1 having the above configuration, when it rains or the like, if water is received on the bottom surface 40 of the recess 4 of the lid 3, this water can be flowed to the outer peripheral edge of the lid 3 by the inclination of the bottom surface 40. Therefore, in the container 1 of Embodiment 1, the inclination of the bottom surface 40 of the recess 4 can regulate the flowing direction of the water received on the upper surface of the lid 3, so that it is easy to suppress the intrusion of water into the container 1.

[0011] 2. Details Subsequently, with reference to the drawings, the container 1 of the present embodiment shown in Figures 1 to 8 will be described in more detail. In the container 1 of the present embodiment, the lid 3 includes a first lid 3a rotatably connected to the container body 2 so as to open and close a part of the opening 20, and a second lid 3b rotatably connected to the container body 2 so as to open and close the remaining part of the opening 20.

[0012] 2-1. Container Body As shown in FIG. 1, the container body 2 is box-shaped with an opening 20 on its upper surface. The container body 2 is in the shape of a substantially rectangular parallelepiped box. Hereinafter, the longitudinal direction of the container body 2 in plan view will be referred to as the left-right direction, the short-side direction of the container body 2 in plan view will be referred to as the front-back direction, and the direction orthogonal to the left-right direction and the front-back direction will be referred to as the up-down direction, and each component will be described.

[0013] In the present embodiment, as shown in FIG. 2, the container body 2 is foldable. As shown in FIGS. 1 and 2, the container body 2 includes a rectangular plate-shaped bottom wall 21, a rectangular frame-shaped mouth frame 22 located above the bottom wall 21, and four side walls 23 detachably attached between the bottom wall 21 and the mouth frame 22. Each of the bottom wall 21, the mouth frame 22, and the four side walls 23 is made of synthetic resin.

[0014] The four side walls 23 are composed of a pair of first side walls 24 erected at the ends along the two short sides of the bottom wall 21 (that is, the left and right ends), and a pair of second side walls 25 erected at the ends along the two long sides of the bottom wall 21 (that is, the front and back ends).

[0015] Each of the pair of first side walls 24 is composed of a single plate material. Each of the pair of first side walls 24 is detachable from the front and back ends of the bottom wall 21 and is also detachable from the mouth frame 22. A fitting structure (specifically, a recess) for fitting with the bottom wall 21 is provided at one end (lower end) of each of the pair of first side walls 24.

[0016] Each of the pair of second side walls 25 is composed of two plate materials rotatably connected to each other. Each of the pair of second side walls 25 can be switched between an assembled state in which the two plate materials are arranged side by side in a single plate shape and a folded state in which the two plate materials are stacked in the thickness direction. Each of the pair of second side walls 25 is detachable from the front and back ends of the bottom wall 21 and is also detachable from the mouth frame 22. Each of the pair of second side walls 25 is erected at the front and back ends of the bottom wall 21 in the assembled state. A fitting structure (specifically, a recess) for fitting with the bottom wall 21 is provided at the lower end of each of the pair of second side walls 25.

[0017] As shown in FIG. 3, the bottom wall 21 integrally includes a rectangular plate-shaped bottom wall main body 210 that constitutes the main body, a rectangular frame-shaped lower frame 211 that protrudes upward from the outer peripheral edge of the bottom wall main body 210, and a fitting structure (specifically, a convex portion 212) provided on the outer peripheral portion of the upper surface of the bottom wall main body 210 (the portion inside the lower frame 211). The convex portions 212 are respectively provided at the front and rear end portions and the left and right end portions of the upper surface of the bottom wall main body 210.

[0018] As shown in FIG. 1, the mouth frame 22 integrally includes a pair of short side frames 220 detachably connected to the upper end portions of a pair of first side walls 24, and a pair of long side frames 221 detachably connected to the upper end portions of a pair of second side walls 25.

[0019] As shown in FIGS. 1 and 2, on the upper surfaces of the respective pair of long side frames 221, connecting portions 222 to which the lids 3a and 3b are rotatably connected are provided. On the upper surfaces of the respective pair of short side frames 220, protrusions 223 are provided. In the present embodiment, two protrusions 223 are provided at the upper end portions of the respective pair of short side frames 220.

[0020] As shown in FIG. 1, the container body 2 can be assembled into a box shape by standing four side walls 23 (side walls 24 and 25) on the outer peripheral portion of the upper surface of the bottom wall main body 210 of the bottom wall 21, fitting the bottom wall 21 and the four side walls 23 together, and fitting the mouth frame 22 into the upper end portions of the four side walls 23.

[0021] Further, as shown in FIGS. 2 and 3, the container body 2 can be assembled in a folded state by folding the four side walls 23 and storing them in the space surrounded by the lower frame 211 of the bottom wall 21 and the mouth frame 22.

[0022] In the folded state, on the bottom wall body 210 of the bottom wall 21, a pair of second side walls 25 in the folded state are placed side by side in the front-rear direction. And on the pair of second side walls 25, one of the pair of first side walls 24 is placed in parallel. And the other first side wall 24 has one end (the end on the inner side in the left-right direction) placed on the one first side wall 24 and the other end (the end on the outer side in the left-right direction) placed on the pair of second side walls 25, and is arranged in an inclined state. In the present embodiment, the other (upper) first side wall 24 is located below the lids 3a and 3b at the position where the opening 20 of the mouth frame 22 is closed.

[0023] 2-2. The first lid and the second lid As shown in FIG. 2, the first lid 3a and the second lid 3b have the same shape. Hereinafter, the first lid 3a for opening and closing the rear half of the opening 20 of the container body 2 will be described in detail.

[0024] As shown in FIGS. 4 and 5, the first lid 3a has a substantially rectangular plate-shaped lid body 30 and a connecting portion 31 provided at one end (the rear end) of the lid body 30. The connecting portion 31 is rotatably connected to the connecting portion 222 of the mouth frame 22.

[0025] The upper surface of the lid body 30 has a first concave portion 4a recessed downward. In the present embodiment, two first concave portions 4a are provided on the upper surface of the lid body 30 at intervals in the left-right direction (the longitudinal direction of the lid body 30). The upper surface of the lid body 30 further has a first drain groove portion 5a recessed downward that connects a part of the outer peripheral edge of the first lid 3a and the first concave portion 4a. In the present embodiment, two first drain groove portions 5a are provided on the upper surface of the lid body 30. The two first drain groove portions 5a are located at the rear end of the lid body 30 (the end opposite to the second lid 3b).

[0026] At each of the left and right ends of the lid body 30, fitting holes 32 into which the protrusions 223 (see FIG. 2) of the mouth frame 22 are fitted are provided. The fitting holes 32 penetrate the lid body 30 in the vertical direction (the thickness direction). The upper surface of the lid body 30 further has a flat portion 33 located between the two first concave portions 4a. The flat portion 33 is a surface orthogonal to the thickness direction of the lid body 30.

[0027] Of the lid body 30, the entire remaining portion excluding the recesses such as the first recess 4a and the first drain groove portion 5a and the fitting holes 32 has a constant wall thickness (length in the vertical direction).

[0028] Each of the two first recesses 4a is disposed at a position away from the front end of the lid body 30 (that is, the edge on the side adjacent to the second lid 3b) and at a position away from the rear end of the lid body 30 (that is, the connecting portion 31). Further, each of the two first recesses 4a is disposed at a position away from the left and right fitting holes 32.

[0029] Each of the two first recesses 4a has a bottom surface 40a provided one step lower than the flat surface portion 33. The bottom surface 40a slopes downward toward the rear side (the side opposite to the second lid 3b). Here, the downward slope is not limited to inclining at a constant angle over the entire length in the front-rear direction, and also includes a case where a flat surface portion with a constant height is included in a part of the front-rear direction.

[0030] In the present embodiment, the bottom surface 40a includes a first inclined portion 400 and a second inclined portion 401 formed by flat surfaces sloping downward in different directions. The first inclined portion 400 has a right-angled triangular shape in plan view, and the second inclined portion 401 has a trapezoidal shape in plan view. A straight line portion 402 is formed at the boundary between the first inclined portion 400 and the second inclined portion 401.

[0031] The first inclined portion 400 has a constant height of the front end side edge 403 over the entire length in the left-right direction, and is inclined so that the rear side portion is located lower as shown in FIG. 6. The second inclined portion 401 has a constant height of the inner side edge 404 in the left-right direction over the entire length in the front-rear direction, and is inclined so that the outer side portion in the left-right direction is located lower as shown in FIG. 7. The front end side edge 403 of the first inclined portion 400 and the inner side edge 404 in the left-right direction of the second inclined portion 401 have the same height (position in the vertical direction). Therefore, the short-side first inclined portion 400 and the long-side second inclined portion 401 are inclined from straight line portions (side edges 403, 404) having the same height. The first inclined portion 400 has a steeper gradient than the second inclined portion 401.

[0032] As a result, on the bottom surface 40a, as shown in FIG. 6, on a straight line (line B-B) parallel to the front-rear direction, the portion corresponding to the first inclined portion 400 is inclined downward to the rear, and the height is constant in the portion corresponding to the second inclined portion 401.

[0033] In the present embodiment, the first drain groove portion 5a is disposed at the rear end portion (the end portion on the side opposite to the second lid 3b) among the outer peripheral edges on the left and right sides of the first lid 3a and the first recess 4a. The first drain groove portion 5a extends in the longitudinal direction of the lid body 30.

[0034] The first drain groove portion 5a has a bottom surface 50a that is continuous with the bottom surface 40a of the first recess 4a. In the present embodiment, the bottom surface 50a is continuous with the second inclined portion 401 of the bottom surface 40a. As shown in FIG. 7, the bottom surface 50a is not inclined downward at the same angle as the second inclined portion 401 and is not located on the same plane as the second inclined portion 401.

[0035] The bottom surface 50a is inclined upward toward a part of the outer peripheral edge of the lid body 30 (the edge on the outer side in the left-right direction). Thereby, in the portion of the outer peripheral edge of the lid body 30 where the first drain groove portion 5a is provided, it is possible to suppress a decrease in the thickness of the lid body 30, and it is easy to ensure the rigidity of the outer peripheral edge of the lid body 30.

[0036] As shown in FIGS. 6 and 8, the first lid 3a extends along the end portion on the side adjacent to the second lid 3b and has a first reinforcing rib group 6a that protrudes downward. In the present embodiment, the first reinforcing rib group 6a is composed of three ribs 60, 61, and 62 that are ridges protruding downward from the front end portion of the lid body 30 (specifically, a position at a distance from the front end). The lid body 30 has an overlapping portion 34 located outside (front side) of the rib 60.

[0037] Each of the three ribs 60, 61, and 62 extends in the left-right direction and is located over the entire length in the left-right direction in the remaining portion of the first lid 3a except for the left and right end portions. The three ribs 60, 61, and 62 are parallel to each other and are spaced apart.

[0038] The lid main body 30 further has a reinforcing rib group 7a extending along the end portion on the side opposite to the second lid 3b and protruding downward, and a reinforcing rib group 8a extending along the left and right end portions of the lid main body 30 and protruding downward. The reinforcing rib group 7a is composed of two ribs 70 and 71 which are ridges extending in the left-right direction, and each of the left and right reinforcing rib groups 8a is composed of two ribs 80 and 81 which are ridges extending in the front-rear direction.

[0039] The first reinforcing rib group 6a, the reinforcing rib group 7a, and the pair of left and right reinforcing rib groups 8a are connected in a rectangular frame shape. Thereby, the overall deformation of the lid main body 30 is suppressed. The first reinforcing rib group 6a, the reinforcing rib group 7a, and the pair of left and right reinforcing rib groups 8a are arranged at positions spaced apart from the outer peripheral edge of the lid main body 30. Thereby, in a state where the opening 20 is closed by the first lid 3a, the first reinforcing rib group 6a, the reinforcing rib group 7a, and the pair of left and right reinforcing rib groups 8a are arranged inside the mouth frame 22, that is, they do not rest on the mouth frame 22.

[0040] The second lid 3b shown in FIG. 2 has the same structure as that obtained by rotating the first lid 3a by 180 degrees around the vertical axis passing through the center of the first lid 3a. In FIG. 2, the same reference numerals are given to the components common to the configuration of the first lid 3a.

[0041] The upper surface of the second lid 3b has a second concave portion 4b corresponding to the first concave portion 4a of the first lid 3a and a second drain groove portion 5b corresponding to the first drain groove portion 5a of the first lid 3a.

[0042] The bottom surface 40b of the second concave portion 4b slopes downward toward the side opposite to the first lid 3a. The bottom surface 40b includes a first inclined portion 400 and a second inclined portion 401. On the bottom surface 40b, on a straight line parallel to the front-rear direction, in the portion corresponding to the first inclined portion 400, it slopes downward, and in the portion corresponding to the second inclined portion 401, the height is constant.

[0043] The second drain groove portion 5b connects a part of the outer peripheral edge of the second lid 3b (specifically, the edges on the left and right outer sides of the second lid 3b) and the second recess 4b. The second drain groove portion 5b is located at the end portion (i.e., the front end portion) of the second lid 3b on the side opposite to the first lid 3a.

[0044] As shown in FIG. 3, the second lid 3b has a second reinforcing rib group 6b corresponding to the first reinforcing rib group 6a of the first lid 3a. The second reinforcing rib group 6b extends along the end portion (i.e., the rear end portion) of the second lid 3b on the side adjacent to the first lid 3a and protrudes downward. The second reinforcing rib group 6b is composed of three ribs 60, 61, and 62. The second lid 3b has an overlapping portion 34 outside (rear side) of the second reinforcing rib group 6b.

[0045] 2-3. Others In the container 1 having the first lid 3a and the second lid 3b described above, as shown in FIGS. 2 and 3, the first lid 3a and the second lid 3b close the entire opening 20 of the container body 2. At this time, for example, the overlapping portion 34 of the first lid 3a is placed on the overlapping portion 34 of the second lid 3b. Thereby, the upper surface (flat portion 33) of the second lid 3b becomes parallel to the horizontal plane, and the upper surface (flat portion 33) of the first lid 3a is slightly inclined downward at the rear.

[0046] Also, when a plurality of containers 1 of the present embodiment are stacked vertically, the bottom surface (the lower surface of the bottom wall 21) of the upper container 1 is placed on the protrusion 223 of the lower container 1, and a gap is generated between the lids 3a and 3b of the lower container 1 and the bottom surface of the upper container 1. In the container 1 of the present embodiment, during stacking, the protrusion 223 of the lower container 1 can be hooked on the bottom surface of the upper container 1 to suppress the displacement of the upper container 1.

[0047] 3. Operational Effects In the container 1 of the present embodiment described above, when rainwater is received on the upper surface of the lid 3 during rain or the like, drainage can be performed as follows.

[0048] That is, in the container 1 of the present embodiment, the water on the first inclined portion 400 of the bottom surface 40a of the first recess 4a of the first lid 3a can flow rearward due to the inclination of the first inclined portion 400. And the water on the second inclined portion 401 of the bottom surface 40b can flow outward in the lateral direction due to the inclination of the second inclined portion 401. Thereby, in the first lid 3a, the rainwater received on the bottom surface 40a can be made to flow through the first drain groove portion 5a to the edges on the outer sides in the lateral direction of the rear end portion of the first lid 3a among the outer peripheral edges of the first lid 3a.

[0049] Therefore, in the container 1 of the present embodiment, the first recess 4a and the first drain groove portion 5a of the first lid 3a enable drainage while avoiding the connection portion 31, the fitting hole 32, and the overlapping portion 34 of the first lid 3a, and can suppress rainwater from entering the container 1. Also, the water received by the second lid 3b can be drained in the same manner as the first lid 3a, and rainwater can be suppressed from entering the container 1.

[0050] Further, in the container 1 of the present embodiment, when the first lid 3a is slightly tilted by the second lid 3b in a state where the opening 20 of the container body 2 is closed by the first lid 3a and the second lid 3b. Therefore, in the first lid 3a, the inclination of the bottom surface 40a of the first recess 4a becomes larger, making it easier to drain water.

[0051] Also, in the container 1 of the present embodiment, when a plurality of containers 1 are stacked vertically, the flat portions 33 of the lids 3a, 3b of the lower container 1 and the bottom surface of the upper container 1 are separated from each other, and gaps are formed between the bottom surfaces 40a, 40b of the recesses 4a, 4b of the lids 3a, 3b of the lower container 1 and the bottom surfaces 50a, 50b of the drain groove portions 5a, 5b and the bottom surface of the upper container 1. Therefore, in the container 1 of the present embodiment, the rainwater received on the lids 3a, 3b of the lower container 1 can also be drained in the same manner as the upper container 1. At this time, the flat portions 33 of the lids 3a, 3b of the lower container 1 and the bottom surface of the upper container 1 may be in contact with each other.

[0052] Also, in the container 1 of the present embodiment, since the bottom surfaces 40a, 40b of the recesses 4a, 4b are flat and have no irregularities, water hardly stays on the bottom surfaces 40a, 40b, and it is easy to drain water.

[0053] Also, in the container 1 of the present embodiment, since the first lid 3a and the second lid 3b have the same shape, there is no mistake in attaching the lids 3a and 3b to the front and rear connecting portions 222 of the container body 2, and it is easy to assemble.

[0054] 4. Modification Subsequently, a modification of the container 1 of the above-described Embodiment 1 will be described. Each of the modifications described below can be appropriately combined.

[0055] The container body 2 only needs to be a box-shaped one having an opening 20 on the upper surface, and is not limited to the foldable one as shown in FIGS. 1 and 2, and may be an integrally molded product.

[0056] The lid 3 only needs to have a recess 4 on the upper surface of the lid 3, and the bottom surface 40 of the recess 4 is inclined downward toward the outer peripheral edge of the lid 3, and is not limited to the one including the first lid 3a and the second lid 3b. The lid 3 may be composed of one member or three or more members.

[0057] When the lid 3 is composed of one member, the bottom surface 40 of the recess 4 only needs to be inclined downward toward the outer peripheral edge of the lid 3. In this case, the bottom surface 40 may have at least one of a surface inclined downward toward the front edge of the lid 3, a surface inclined downward toward the rear edge of the lid 3, a surface inclined downward toward the right edge of the lid 3, and a surface inclined downward toward the left edge of the lid 3. Here, the downward inclination is not limited to the case where it is inclined at a predetermined angle over the entire length, and also includes the case where a flat surface portion parallel to the horizontal plane is included in part.

[0058] The lid body 30 may have a constant overall wall thickness including the recesses such as the first recess 4a and the first drain groove portion 5a, and the portion where the fitting hole 32 is located. Further, the lid body 30 may be formed such that the wall thickness gradually decreases from the center of the lid body 30 toward the outside. Also, the wall thickness of the portion of the lid body 30 where the first drain groove portion 5a is located may be thinner than the wall thickness of the portion of the lid body 30 where the first recess 4a is located. Further, the portion of the lid body 30 where the first drain groove portion 5a is located and the portion where the first recess 4a is located may have the same wall thickness. In this case, a recess may be provided in the portion of the upper surface of the mouth frame 22 corresponding to the first drain groove portion 5a.

[0059] Each of the bottom surfaces 40a of the first recess 4a and the bottom surface 40b of the second recess 4b does not have to include both the first inclined portion 400 and the second inclined portion 401. For example, the bottom surfaces 40a and 40b may be downwardly inclined as a whole toward the outside in the front-rear direction, or may be downwardly inclined toward the outside in the left-right direction. Also in this case, the bottom surfaces 40a and 40b may include a flat portion parallel to the horizontal plane in part.

[0060] Also, the arrangement of the recesses 4a and 4b on the upper surfaces of the lids 3a and 3b is not limited to the arrangement shown in FIG. 2. For example, the recesses 4a and 4b may be located from the central portion in the left-right direction of the lids 3a and 3b to the edges on the outside in the left-right direction. In this case, the drain groove portions 5a and 5b are omitted. Also in this case, it is preferable that the lids 3a and 3b are provided with an annular weir protruding upward so as to surround the fitting hole 32 on the bottom surfaces 40a and 40b of the recesses 4a and 4b.

[0061] Also, the lids 3a and 3b may have a weir protruding upward around the connecting portion 31 or over the entire length in the left-right direction of the edges on the outside in the front-rear direction of the lid body 30. In these cases, it is possible to suppress rainwater passing over the upper surfaces of the lids 3a and 3b from entering the container body 2 through the gap around the connecting portion 31 by means of the weir.

[0062] Also, the lids 3a and 3b do not have to have a flat portion 33 between the two recesses 4a and 4b, and the two recesses 4a and 4b may be connected.

[0063] Also, the arrangement of the drain grooves 5a and 5b on the upper surfaces of the lids 3a and 3b may be located at the end of the first lid 3a on the side opposite to the second lid 3b and at the end of the second lid 3b on the side opposite to the first lid 3a, and is not limited to the arrangement shown in FIG. 2. The drain grooves 5a and 5b may be provided, for example, between the recesses 4a and 4b and the outer edges of the lids 3a and 3b in the front-rear direction (outside the left-right direction of the connecting portion 31) so as to extend in the front-rear direction.

[0064] Also, the lids 3a and 3b may not have the reinforcing rib groups 6a and 6b. Also, the number of ribs constituting the reinforcing rib groups 6a and 6b is not limited to three, and may be two or four or more.

[0065] Also, the bottom surfaces 40a and 40b of the recesses 4a and 4b of the lids 3a and 3b may be formed as corrugated surfaces.

[0066] Also, each of the lids 3a and 3b may further have a rib with a protrusion extending upward from the tip of the overlapping portion 34 and extending in the left-right direction, and a rib with a protrusion extending downward from the tip of the overlapping portion 34 and extending in the left-right direction. In this case, not only can the strength of the overlapping portion 34 be improved, but it is also easy to suppress water from entering the container 1 from the portion where the overlapping portions 34 of the lids 3a and 3b are overlapped by the ribs with protrusions.

[0067] Also, the first lid 3a and the second lid 3b are not limited to the same shape. The first lid 3a and the second lid 3b only need to have at least the recesses 4a and 4b, and the arrangement, shape, size, or number of the recesses 4a and 4b in each lid 3a and 3b may be different.

[0068] Also, in the state where the opening 20 of the container body 2 is closed by the lids 3a and 3b with respect to the container body 2 in the folded state, the reinforcing rib group 6a (or 6b) of the lid located on the lower side among the lids 3a and 3b may contact the first side wall 24 on the short side. In this case, it is easy to maintain the horizontal state of the lids 3a and 3b, and it is easy to prevent the central portion of the lids 3a and 3b in the longitudinal direction (left-right direction) from deforming downward.

[0069] (Embodiment 2) Next, the container 1 of Embodiment 2 shown in FIGS. 9 and 10 will be described in detail with reference to the drawings. Hereinafter, among the components of the container 1 of Embodiment 2, for the components common to Embodiment 1, the same reference numerals are given in the drawings and the detailed description thereof is omitted, and for the components different from Embodiment 1, they will be described in detail.

[0070] In addition to each component of the container 1 of Embodiment 1, the container 1 of Embodiment 2 includes an inclination means 9 for inclining the first lid 3a and the second lid 3b in a state where the opening 20 is closed. As shown in FIG. 10, the inclination means 9 is configured to incline the first lid 3a and the second lid 3b such that the upper surface of the first lid 3a slopes downward toward the side opposite to the second lid 3b, and the upper surface of the second lid 3b slopes downward toward the side opposite to the first lid 3a.

[0071] In the present embodiment, the inclination means 9 is at least one of a first reinforcing rib group 6a protruding downward from an end portion of the first lid 3a adjacent to the second lid 3b and a second reinforcing rib group 6b protruding downward from an end portion of the second lid 3b adjacent to the first lid 3a. When at least one of the first reinforcing rib group 6a and the second reinforcing rib group 6b hits the side wall 23 in the folded state of the container body 2, the first lid 3a and the second lid 3b are inclined.

[0072] More specifically, in the present embodiment, among the first reinforcing rib group 6a (that is, ribs 60, 61, 62), the rib 60 closest to the second lid 3b is provided longer in the vertical direction than the other ribs 61, 62.

[0073] Also, among the second reinforcing rib group 6b (that is, ribs 60, 61, 62), the rib 60 closest to the first lid 3a is provided longer in the vertical direction than the other ribs 61, 62.

[0074] In the present embodiment, as shown in FIG. 9, the bottom surface 40a of the first recess 4a is parallel to the flat surface portion 33. Also, the bottom surface 50a of the first drain groove portion 5a is parallel to the flat surface portion 33 of the first lid 3a. Similarly, the bottom surface 40b of the second recess 4b and the bottom surface 50b of the second drain groove portion 5b are parallel to the flat surface portion 33 of the second lid 3b.

[0075] In the container 1 of the present embodiment, for example, as shown in FIG. 10, when the container body 2 is in a folded state, the lid 3a, 3b are arranged such that the overlapping portion 34 of the first lid 3a lies on the overlapping portion 34 of the second lid 3b to close the opening 20 of the container body 2. At this time, the rib 60 of the second reinforcing rib group 6b of the second lid 3b hits the side wall 23 (specifically, the first side wall 24) in the folded state of the container body 2, and the upper surface of the second lid 3b inclines forward and downward with respect to the horizontal plane. The first lid 3a inclines backward and downward with respect to the horizontal plane because the overlapping portion 34 of the first lid 3a lies on the overlapping portion 34 of the second lid 3b.

[0076] Alternatively, the overlapping portion 34 of the second lid 3b may be arranged to lie on the overlapping portion 34 of the first lid 3a. In this case, the rib 60 of the first reinforcing rib group 6a of the first lid 3a hits the first side wall 24 in the folded state of the container body 2, and the upper surface of the first lid 3a inclines backward and downward with respect to the horizontal plane. The second lid 3b inclines forward and downward with respect to the horizontal plane because the overlapping portion 34 of the second lid 3b lies on the overlapping portion 34 of the first lid 3a.

[0077] As a result, in the container 1 of the present embodiment, the rainwater received on the upper surfaces of the lids 3a, 3b can be made to flow in a direction away from the overlapping portion 34 of the lids 3a, 3b. The rainwater flowing on the bottom surfaces 40a, 40b of the recesses 4a, 4b can be drained to the outside of the lids 3a, 3b through the drain groove portions 5a, 5b while accumulating at the outer ends in the front-rear direction of the bottom surfaces 40a, 40b. At this time, the wall surfaces at the outer ends in the front-rear direction of the recesses 4a, 4b prevent the rainwater from crossing the recesses 4a, 4b and reaching the connecting portion 31. Also, the wall surfaces at the outer ends in the left-right direction of the recesses 4a, 4b prevent the rainwater from crossing the recesses 4a, 4b and reaching the fitting holes 32.

[0078] Therefore, also in the container 1 of the second embodiment, drainage can be performed while avoiding the connecting portion 31, the fitting holes 32, and the overlapping portion 34 of the lids 3a, 3b, and it is possible to suppress the intrusion of rainwater into the container 1.

[0079] The container 1 of the second embodiment described above can also appropriately adopt the same modification examples as the container 1 of the first embodiment.

[0080] Also, in the container 1 of the second embodiment, the reinforcing rib groups 6a and 6b are not limited to those in which the rib 60 is provided longer than the other ribs 61 and 62 as shown in FIG. 10. For example, in the reinforcing rib groups 6a and 6b, the rib 62 or the rib 61 may be provided longer than the other ribs, or all of the ribs 60, 61, and 62 may be provided longer in the vertical direction than the reinforcing rib groups 7a and 8a (see FIG. 8).

[0081] Also, the tilting means 9 does not have to be the reinforcing rib groups 6a and 6b. For example, it may be constituted by protrusions provided on the first side wall 24, or may be constituted by a dedicated member provided separately from the lids 3a and 3b and the first side wall 24.

[0082] Also, the upper surfaces of the lids 3a and 3b do not have to have the recesses 4a and 4b and the drain groove portions 5a and 5b, and may be provided as a flat surface.

[0083] Also, the bottom surfaces 40a and 40b of the recesses 4a and 4b may be surfaces that slope downward toward the outer peripheral edge of the lids 3a and 3b, similar to the recesses 4a and 4b of the first embodiment.

[0084] (Summary) As in the first embodiment and its modification examples described above, the container 1 of the first aspect has the following configuration.

[0085] That is, the container 1 of the first aspect includes a box-shaped container body 2 having an opening 20 on the upper surface, and a lid 3 rotatably connected to the container body 2 so as to open and close the opening 20. The upper surface of the lid 3 has a recess 4. The bottom surface 40 of the recess 4 slopes downward toward the outer peripheral edge of the lid 3.

[0086] In the container 1 of the first aspect having the above configuration, when it rains or the like, when water is received on the bottom surface 40 of the concave portion 4 of the lid 3, this water can be made to flow toward the outer peripheral edge of the lid 3 by the inclination of the bottom surface 40. Therefore, in the container 1 of the first aspect, the inclination of the bottom surface 40 of the concave portion 4 can regulate the flowing direction of the water received on the upper surface of the lid 3, so that it is easy to suppress the intrusion of water into the container 1.

[0087] Also, like the above-described Embodiment 1 and its modification, the container 1 of the second aspect additionally includes the following configuration in addition to the configuration of the container 1 of the first aspect.

[0088] That is, in the container 1 of the second aspect, the lid 3 includes a first lid 3a rotatably connected to the container body 2 so as to open and close a part of the opening 20, and a second lid 3b rotatably connected to the container body 2 so as to open and close the remaining part of the opening 20. The concave portion 4 includes a first concave portion 4a located on the upper surface of the first lid 3a and a second concave portion 4b located on the upper surface of the second lid 3b. The bottom surface 40a of the first concave portion 4a slopes downward toward the side opposite to the second lid 3b. The bottom surface 40b of the second concave portion 4b slopes downward toward the side opposite to the first lid 3a.

[0089] In the container 1 of the second aspect having the above configuration, the water received on the bottom surface 40a of the first concave portion 4a of the first lid 3a can be made to flow in a direction away from the second lid 3b, and the water received on the bottom surface 40b of the second concave portion 4b of the second lid 3b can be made to flow in a direction away from the first lid 3a. Thereby, in the container 1 of the second aspect, it is easy to suppress water from entering the container 1 through the gap between the first lid 3a and the second lid 3b.

[0090] Also, like the above-described Embodiment 1 and its modification, the container 1 of the third aspect additionally includes the following configuration in addition to the configuration of the container 1 of the second aspect.

[0091] That is, in the container 1 of the third aspect, the upper surface of the first lid 3a has a first drain groove portion 5a that connects a part of the outer peripheral edge of the first lid 3a and the first recess 4a. The upper surface of the second lid 3b has a second drain groove portion 5b that connects a part of the outer peripheral edge of the second lid 3b and the second recess 4b. The first drain groove portion 5a is located at an end of the first lid 3a on the side opposite to the second lid 3b. The second drain groove portion 5b is located at an end of the second lid 3b on the side opposite to the first lid 3a.

[0092] In the container 1 of the third aspect having the above configuration, the water that has flowed along the bottom surface 40a of the first recess 4a of the first lid 3a to the end on the side opposite to the second lid 3b can be drained to the outer peripheral edge of the first lid 3a through the first drain groove portion 5a. Further, in the container 1 of the third aspect, the water that has flowed along the bottom surface 40b of the second recess 4b of the second lid 3b to the end on the side opposite to the first lid 3a can be drained to the outer peripheral edge of the second lid 3b through the second drain groove portion 5b. Thereby, in the container 1 of the third aspect, it is possible to suppress the water flowing along the bottom surfaces 40a and 40b of the recesses 4a and 4b of the lids 3a and 3b from overflowing the recesses 4a and 4b and being drained in an unintended direction.

[0093] Also, like the above-described Embodiment 1 and its modified examples, the container 1 of the fourth aspect additionally includes the following configuration in addition to the configuration of the container 1 of the second or third aspect.

[0094] That is, in the container 1 of the fourth aspect, the first lid 3a has a first reinforcing rib group 6a that extends along the end on the side adjacent to the second lid 3b and protrudes downward. The second lid 3b has a second reinforcing rib group 6b that extends along the end on the side adjacent to the first lid 3a and protrudes downward.

[0095] By having the above configuration, in the container 1 of the fourth aspect, the deflection of each of the lids 3a and 3b can be suppressed by the reinforcing rib groups 6a and 6b, and it is possible to suppress the change in the inclination of the bottom surfaces 40a and 40b of the recesses 4a and 4b of the lids 3a and 3b and the decrease in drainage performance. Further, in the container 1 of the fourth aspect, since the reinforcing rib groups 6a and 6b protrude downward from the lids 3a and 3b, they are not conspicuous.

[0096] Also, like the above-described Embodiment 2 and its modified examples, the container 1 of the fifth aspect has the following configuration.

[0097] That is, in the container 1 of the fifth aspect, a box-shaped container body 2 having an opening 20 on the upper surface, a first lid 3a rotatably connected to the container body 2 so as to open and close a part of the opening 20, and the remaining part of the opening 20 And a second lid 3b rotatably connected to the container body 2 so as to open and close the container 1. The container 1 of the fifth aspect further includes an inclination means 9 for inclining the first lid 3a and the second lid 3b in a state where the opening 20 is closed. The inclination means 9 inclines the first lid 3a and the second lid 3b such that the upper surface of the first lid 3a slopes downward toward the side opposite to the second lid 3b, and the upper surface of the second lid 3b slopes downward toward the side opposite to the first lid 3a.

[0098] By having the above configuration, in the container 1 of the fifth aspect, since the lids 3a and 3b can be inclined by the inclination means 9, it is easy to suppress water received on the upper surfaces of the lids 3a and 3b from entering the container 1 through the gap between the first lid 3a and the second lid 3b. Further, in the container 1 of the fifth aspect, since the lids 3a and 3b can be inclined by the inclination means 9, it is not necessary to manufacture the lids 3a and 3b so as to have an inclination on the upper surface, and the lids 3a and 3b are easy to manufacture.

[0099] Also, like the above-described Embodiment 2 and its modified examples, the container 1 of the sixth aspect additionally has the following configuration in addition to the configuration of the container 1 of the fifth aspect.

[0100] That is, in the container 1 of the sixth aspect, the container body 2 has a foldable side wall 23. The first lid 3a has a first reinforcing rib group 6a extending along an end portion on the side adjacent to the second lid 3b and protruding downward. The second lid 3b has a second reinforcing rib group 6b extending along an end portion on the side adjacent to the first lid 3a and protruding downward. The inclination means 9 is at least one of the first reinforcing rib group 6a and the second reinforcing rib group 6b. At least one of the first reinforcing rib group 6a and the second reinforcing rib group 6b hits the side wall 23 in the folded state of the container body 2, so that the first lid 3a and the second lid 3b are inclined.

[0101] By having the above configuration, in the container 1 of the sixth aspect, it is not necessary to provide the members constituting the tilting means 9 separately from the lids 3a and 3b, and an increase in the number of parts of the container 1 can be suppressed. Further, in the container 1 of the sixth aspect, the respective flexures of the lids 3a and 3b can be suppressed by the reinforcing rib groups 6a and 6b, and it is possible to suppress a change in the inclination of the upper surfaces of the lids 3a and 3b in the tilted state by the tilting means 9, thereby suppressing a decrease in drainage performance.

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