[0010] (Embodiment 1) 1. Overview The lidded transport container 1 (hereinafter simply referred to as "container 1") of embodiment 1 shown in Fig. 1 comprises a box-shaped container body 2 having an opening 20 on its 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. A bottom surface 40 of the recess 4 slopes downward toward the outer periphery of the lid 3.
[0011] In the container 1 of the first embodiment having the above configuration, when water is received on the bottom surface 40 of the recess 4 of the lid 3 during rainfall or the like, the inclination of the bottom surface 40 allows the water to flow toward the outer periphery of the lid 3. Therefore, in the container 1 of the first embodiment, the inclination of the bottom surface 40 of the recess 4 can regulate the flow direction of the water received on the upper surface of the lid 3, making it easy to suppress the intrusion of water into the container 1.
[0012] 2.Details Next, the container 1 of this embodiment shown in Figures 1 to 8 will be described in more detail with reference to the drawings. In the container 1 of this 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.
[0013] 2-1. Container body 1, the container body 2 is box-shaped with an opening 20 on the top surface. The container body 2 is a substantially rectangular box. In the following, each configuration will be described with the longitudinal direction of the container body 2 in a plan view as the left-right direction, the lateral direction of the container body 2 in a plan view as the front-rear direction, and the direction perpendicular to the left-right direction and the front-rear direction as the up-down direction.
[0014] In this embodiment, the container body 2 is foldable as shown in Fig. 2. As shown in Figs. 1 and 2, the container body 2 includes a rectangular plate-shaped bottom wall 21, a rectangular mouth frame 22 located above the bottom wall 21, and four side walls 23 attached so as to be engageable 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.
[0015] 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 (i.e., 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 (i.e., the front and back ends).
[0016] Each of the pair of first side walls 24 is formed of a single plate material. Each of the pair of first side walls 24 is detachable from the front and rear ends of the bottom wall 21, and is also detachable from the mouth frame 22. One end (lower end) of each of the pair of first side walls 24 is provided with a fitting structure (more specifically, a recess) used for fitting with the bottom wall 21.
[0017] 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 in the form of one plate, 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 rear 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 rear ends of the bottom wall 21 in the assembled state. A fitting structure (more specifically, a recess) used for fitting with the bottom wall 21 is provided at the lower end of each of the pair of second side walls 25.
[0018] 3, the bottom wall 21 integrally comprises a rectangular plate-shaped bottom wall main body 210 constituting the main body, a rectangular frame-shaped lower frame 211 protruding upward from the outer periphery of the bottom wall main body 210, and a fitting structure (more specifically, a protruding portion 212) provided on the outer periphery (the inner portion of the lower frame 211) of the upper surface of the bottom wall main body 210. The protruding portions 212 are provided on the front and rear ends and the left and right ends of the upper surface of the bottom wall main body 210.
[0019] As shown in Figure 1, the mouth frame 22 integrally has a pair of short side frames 220 that are detachably connected to the upper ends of the pair of first side walls 24, and a pair of long side frames 221 that are detachably connected to the upper ends of the pair of second side walls 25.
[0020] 1 and 2, a connecting portion 222 to which the lids 3a, 3b are rotatably connected is provided on the upper surface of each of the pair of long-side frames 221. A protrusion 223 is provided on the upper surface of each of the pair of short-side frames 220. In this embodiment, two protrusions 223 are provided on the upper end portion of each of the pair of short-side frames 220.
[0021] As shown in FIG. 1, the container body 2 can be assembled into a box shape by erecting four side walls 23 (side walls 24, 25) on the outer periphery of the upper surface of the bottom wall body 210 of the bottom wall 21, engaging the bottom wall 21 with the four side walls 23, and fitting the mouth frame 22 into the upper ends of the four side walls 23.
[0022] 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.
[0023] In the folded state, the pair of second side walls 25 in the folded state are placed on the bottom wall main body 210 of the bottom wall 21 so as to be aligned in the front-rear direction. One of the pair of first side walls 24 is placed in parallel on the pair of second side walls 25. The other first side wall 24 is placed in an inclined state with one end (the end on the inner side in the left-right direction) placed on one of the first side walls 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. In this embodiment, the other (upper) first side wall 24 is located below the covers 3a and 3b that are in a position to close the opening 20 of the mouth frame 22.
[0024] 2-2. First and second lids 2, the first lid 3a and the second lid 3b have the same shape. The first lid 3a, which opens and closes the rear half of the opening 20 of the container body 2, will be described in detail below.
[0025] 4 and 5, the first lid 3a has a substantially rectangular plate-shaped lid body 30 and a connecting part 31 provided at one end (rear end) of the lid body 30. The connecting part 31 is rotatably connected to the connecting part 222 of the mouth frame 22.
[0026] The upper surface of the lid body 30 has a first recess 4a recessed downward. In this embodiment, two first recesses 4a are provided on the upper surface of the lid body 30 at an interval in the left-right direction (longitudinal direction of the lid body 30). The upper surface of the lid body 30 further has a first drainage groove portion 5a recessed downward, which connects a part of the outer periphery of the first lid 3a and the first recess 4a. In this embodiment, two first drainage groove portions 5a are provided on the upper surface of the lid body 30. The two first drainage groove portions 5a are located at the rear end portion of the lid body 30 (the end portion opposite to the second lid 3b).
[0027] The lid body 30 has fitting holes 32 at both left and right ends thereof into which the protrusions 223 (see FIG. 2) of the mouth frame 22 fit. The fitting holes 32 penetrate the lid body 30 in the up-down direction (thickness direction). The top surface of the lid body 30 further has a flat portion 33 located between the two first recesses 4a. The flat portion 33 is a surface perpendicular to the thickness direction of the lid body 30.
[0028] The entire remaining portion of the lid body 30, excluding the recesses such as the first recess 4a and the first drain groove portion 5a, and the fitting hole 32, has a constant wall thickness (length in the vertical direction).
[0029] Each of the two first recesses 4a is disposed at a position away from the front end of the lid body 30 (i.e., the edge adjacent to the second lid 3b) and at a position away from the rear end of the lid body 30 (i.e., the connecting portion 31). Also, each of the two first recesses 4a is disposed at a position away from the left and right fitting holes 32.
[0030] Each of the two first recesses 4a has a bottom surface 40a that is provided one step lower than the flat surface portion 33. The bottom surface 40a is inclined downward toward the rear side (the side opposite to the second lid 3b). Here, the downward inclination is not limited to an inclination at a constant angle over the entire length in the front-rear direction, but also includes a case where a flat surface portion with a constant height is included in a part of the front-rear direction.
[0031] In this embodiment, the bottom surface 40a includes a first inclined portion 400 and a second inclined portion 401, which are flat surfaces inclined downward in different directions. The first inclined portion 400 has a right-angled triangular shape in a plan view, and the second inclined portion 401 has a trapezoidal shape in a plan view. A straight portion 402 is formed at the boundary between the first inclined portion 400 and the second inclined portion 401.
[0032] The height of the front edge 403 of the first inclined portion 400 is constant over the entire length in the left-right direction, and as shown in FIG. 6, the first inclined portion 400 is inclined so that the rear portion is located lower. The height of the inner edge 404 of the second inclined portion 401 is constant over the entire length in the front-rear direction, and as shown in FIG. 7, the second inclined portion 401 is inclined so that the outer portion is located lower. The front edge 403 of the first inclined portion 400 and the inner edge 404 of the second inclined portion 401 have the same height (position in the up-down direction). Therefore, the first inclined portion 400 on the short side and the second inclined portion 401 on the long side are inclined from the straight portion (edges 403, 404) at the same height. The first inclined portion 400 has a steeper gradient than the second inclined portion 401.
[0033] As a result, on the bottom surface 40a, as shown in Figure 6, on a straight line (line BB) parallel to the front-to-rear direction, the portion corresponding to the first inclined portion 400 is inclined downward toward the rear, and the portion corresponding to the second inclined portion 401 has a constant height.
[0034] In this embodiment, the first drain groove portion 5a is disposed at the rear end portion (the end portion opposite the second cover 3b) between the outer peripheral edge of the first cover 3a in the left-right direction and the first recessed portion 4a. The first drain groove portion 5a extends in the longitudinal direction of the cover body 30.
[0035] The first drain groove portion 5a has a bottom surface 50a that is continuous with the bottom surface 40a of the first recessed portion 4a. In this 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.
[0036] The bottom surface 50a is inclined upward toward a part (the outer edge in the left-right direction) of the outer periphery of the lid body 30. This makes it possible to prevent the thickness of the lid body 30 from becoming thin at the part of the outer periphery of the lid body 30 where the first drain groove portion 5a is located, making it easier to ensure the rigidity of the outer periphery of the lid body 30.
[0037] 6 and 8, the first lid 3a has a first group of reinforcing ribs 6a extending along the end portion adjacent to the second lid 3b and protruding downward. In this embodiment, the first group of reinforcing ribs 6a is composed of three protruding ribs 60, 61, 62 protruding downward from the front end portion of the lid body 30 (more specifically, a position spaced apart from the front end). The lid body 30 has an overlapping portion 34 located outside (on the front side) of the ribs 60.
[0038] Each of the three ribs 60, 61, 62 extends in the left-right direction and is located over the entire left-right length of the first cover 3a except for the left and right ends. The three ribs 60, 61, 62 are parallel to each other and spaced apart.
[0039] The lid body 30 further has a group of reinforcing ribs 7a extending along the end opposite to the second lid 3b and protruding downward, and a group of reinforcing ribs 8a extending along the left and right ends of the lid body 30 and protruding downward. The group of reinforcing ribs 7a is composed of two protruding ribs 70, 71 extending in the left-right direction, and each of the left and right groups of reinforcing ribs 8a is composed of two protruding ribs 80, 81 extending in the front-rear direction.
[0040] 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. This suppresses the overall deformation of the lid body 30. 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 a distance from the outer periphery of the lid body 30. As a result, when 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.
[0041] The second lid 3b shown in Fig. 2 has the same structure as the first lid 3a rotated 180 degrees around a vertical axis passing through the center of the first lid 3a. In Fig. 2, the same reference numerals are used to designate components common to the first lid 3a.
[0042] The upper surface of the second lid 3b has a second recess 4b corresponding to the first recess 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.
[0043] The bottom surface 40b of the second recess 4b is inclined downward toward the opposite side to the first lid 3a. The bottom surface 40b includes a first inclined portion 400 and a second inclined portion 401. On a straight line parallel to the front-rear direction, the bottom surface 40b is inclined downward toward the front at a portion corresponding to the first inclined portion 400, and the height is constant at a portion corresponding to the second inclined portion 401.
[0044] The second drain groove 5b connects a part of the outer peripheral edge of the second cover 3b (more specifically, the outer edge in the left-right direction of the second cover 3b) and the second recess 4b. The second drain groove 5b is located at the end of the second cover 3b opposite to the first cover 3a (i.e., the front end).
[0045] 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 of the second lid 3b adjacent to the first lid 3a (i.e., the rear end) 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 on the outer side (rear side) of the second reinforcing rib group 6b.
[0046] 2-3.Other In the container 1 having the first lid 3a and the second lid 3b described above, as shown in Figures 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. As a result, 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 tilted downward toward the rear.
[0047] Furthermore, when multiple containers 1 of this embodiment are stacked vertically, the bottom surface (the lower surface of the bottom wall 21) of the upper container 1 rests on the protrusion 223 of the lower container 1, and a gap is generated between the lids 3a, 3b of the lower container 1 and the bottom surface of the upper container 1. When the containers 1 of this embodiment are stacked, the protrusions 223 of the lower container 1 are hooked onto the bottom surface of the upper container 1, thereby preventing the upper container 1 from shifting in position.
[0048] 3. 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, the water can be drained as follows.
[0049] That is, in the container 1 of this embodiment, 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 water on the second inclined portion 401 of the bottom surface 40b can flow outward in the left-right direction due to the inclination of the second inclined portion 401. As a result, in the first lid 3a, rainwater received on the bottom surface 40a can flow through the first drain groove portion 5a to the edge of the outer periphery of the first lid 3a that is on the outer left-right direction of the rear end portion of the first lid 3a.
[0050] Therefore, in the container 1 of this embodiment, the first recess 4a and the first drainage groove 5a of the first lid 3a allow water to be drained while avoiding the connecting portion 31, the fitting hole 32, and the overlapping portion 34 of the first lid 3a, thereby preventing rainwater from entering the container 1. Moreover, water received by the second lid 3b can also be drained in the same way as the first lid 3a, preventing rainwater from entering the container 1.
[0051] In the container 1 of this embodiment, the first lid 3a is slightly tilted by the second lid 3b when 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 large, making it easier to drain the water.
[0052] In addition, in the containers 1 of this embodiment, when multiple containers are stacked vertically, the flat surface 33 of the lids 3a, 3b of the lower container 1 and the bottom surface of the upper container 1 are located apart, and a gap is generated 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 drainage grooves 5a, 5b and the bottom surface of the upper container 1. Therefore, in the container 1 of this embodiment, rainwater received on the lids 3a, 3b of the lower container 1 can be drained in the same way as the upper container 1. In this case, the flat surface 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.
[0053] Furthermore, in the container 1 of this embodiment, the bottom surfaces 40a, 40b of the recesses 4a, 4b are flat and have no irregularities, so that water is less likely to remain on the bottom surfaces 40a, 40b and can be easily drained.
[0054] In addition, in the container 1 of this embodiment, the first lid 3a and the second lid 3b have the same shape, so that the lids 3a, 3b are not mistakenly attached to the front and rear connecting parts 222 of the container body 2, making assembly easy.
[0055] 4. Variations Next, a description will be given of modified examples of the container 1 of the above-mentioned embodiment 1. The modified examples described below can be appropriately combined.
[0056] The container body 2 may be a box-like one having an opening 20 on the upper surface, and is not limited to a foldable one as shown in Figs. 1 and 2, but may be an integrally molded product.
[0057] The lid 3 is not limited to including the first lid 3a and the second lid 3b, as long as it has 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 periphery of the lid 3. The lid 3 may be composed of one member, or may be composed of three or more members.
[0058] When the lid 3 is composed of a single member, the bottom surface 40 of the recess 4 may be inclined downward toward the outer periphery 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, inclined downward is not limited to a surface inclined at a predetermined angle over the entire length, but also includes a surface that includes a flat portion that is parallel to the horizontal plane.
[0059] The lid body 30 may have a constant overall thickness, including the recesses such as the first recess 4a and the first drainage groove 5a, and the fitting hole 32. The lid body 30 may be formed so that the thickness gradually decreases from the center of the lid body 30 toward the outside. The thickness of the portion of the lid body 30 where the first drainage groove 5a is located may be thinner than the thickness of the portion of the lid body 30 where the first recess 4a is located. The portion of the lid body 30 where the first drainage groove 5a is located and the portion of the lid body 30 where the first recess 4a are located may have the same thickness, and in this case, a recess may be provided in the portion of the upper surface of the mouth frame 22 that corresponds to the first drainage groove 5a.
[0060] Each of the bottom surface 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, 40b may be entirely inclined downward toward the outside in the front-rear direction, or may be inclined downward toward the outside in the left-right direction. In this case, the bottom surfaces 40a, 40b may also partially include a flat portion parallel to the horizontal plane.
[0061] The arrangement of the recesses 4a, 4b on the upper surfaces of the lids 3a, 3b is not limited to the arrangement shown in Fig. 2. For example, the recesses 4a, 4b may be located from the center to the outer edge in the left-right direction of the lids 3a, 3b, in which case the drain grooves 5a, 5b are omitted. In this case, it is preferable that the lids 3a, 3b have an annular dam on the bottom surfaces 40a, 40b of the recesses 4a, 4b, which protrude upward to surround the fitting hole 32.
[0062] The lids 3a and 3b may have a dam that protrudes upward around the connecting portion 31 on the outer edge in the front-rear direction of the lid body 30, or along the entire length of this edge in the left-right direction. In this case, the dam can prevent rainwater running down the upper surfaces of the lids 3a and 3b from entering the container body 2 through the gap around the connecting portion 31.
[0063] Furthermore, the covers 3a and 3b do not necessarily have to have the flat surface 33 between the two recesses 4a and 4b, and the two recesses 4a and 4b may be connected to each other.
[0064] The arrangement of the drain grooves 5a, 5b on the upper surfaces of the lids 3a, 3b need only be at the end of the first lid 3a opposite the second lid 3b and at the end of the second lid 3b opposite the first lid 3a, and is not limited to the arrangement shown in Fig. 2. The drain grooves 5a, 5b may be provided, for example, between the recesses 4a, 4b and the outer edges of the lids 3a, 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.
[0065] Furthermore, the lids 3a, 3b do not necessarily have to have the reinforcing rib groups 6a, 6b. Furthermore, the number of ribs constituting the reinforcing rib groups 6a, 6b is not limited to three, and may be two or four or more.
[0066] Furthermore, the bottom surfaces 40a, 40b of the recesses 4a, 4b of the lids 3a, 3b may be formed as textured surfaces.
[0067] Furthermore, each of the lids 3a, 3b may further have a protruding rib that protrudes upward from the tip of the overlapping portion 34 and extends in the left-right direction, and a protruding rib that protrudes downward from the tip of the overlapping portion 34 and extends in the left-right direction. In this case, the strength of the overlapping portion 34 can be improved, and the protruding rib can easily prevent water from entering the container 1 from the overlapping portion of the overlapping portions 34 of the lids 3a, 3b.
[0068] In addition, the first lid 3a and the second lid 3b are not limited to having 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 of the lids 3a and 3b may be different.
[0069] Furthermore, in the container 1, when the container body 2 is in a folded state and the opening 20 of the container body 2 is closed by the lids 3a, 3b, the reinforcing rib group 6a (or 6b) of the lid located on the lower side of the lids 3a, 3b may abut against the first side wall 24 on the short side. In this case, it is easy to maintain the horizontal state of the lids 3a, 3b, and it is easy to prevent the central parts of the lids 3a, 3b in the longitudinal direction (left-right direction) from deforming downward.
[0070] (Embodiment 2) Next, the container 1 of the second embodiment shown in Figures 9 and 10 will be described in detail with reference to the drawings. In the following, the configurations of the container 1 of the second embodiment that are common to the first embodiment will be denoted by the same reference numerals in the drawings and detailed description will be omitted, and the configurations that differ from the first embodiment will be described in detail.
[0071] The container 1 of the second embodiment includes, in addition to each configuration of the container 1 of the first embodiment, a tilting means 9 that tilts the first lid 3a and the second lid 3b in a state in which the opening 20 is closed. As shown in Fig. 10, the tilting means 9 is configured to tilt the first lid 3a and the second lid 3b such that the upper surface of the first lid 3a is tilted downward toward the opposite side to the second lid 3b, and the upper surface of the second lid 3b is tilted downward toward the opposite side to the first lid 3a.
[0072] In this embodiment, the tilting means 9 is at least one of a first reinforcing rib group 6a protruding downward from an end of the first lid 3a on the side adjacent to the second lid 3b and a second reinforcing rib group 6b protruding downward from an end of the second lid 3b on the side adjacent to the first lid 3a. At least one of the first reinforcing rib group 6a and the second reinforcing rib group 6b hits the side wall 23 of the container body 2 in the folded state, thereby tilting the first lid 3a and the second lid 3b.
[0073] More specifically, in this embodiment, of the first reinforcing rib group 6a (that is, the ribs 60, 61, 62), the rib 60 closest to the second cover 3b is provided longer than the other ribs 61, 62 in the vertical direction.
[0074] Furthermore, of the second reinforcing rib group 6b (that is, the ribs 60, 61, 62), the rib 60 closest to the first cover 3a is provided longer than the other ribs 61, 62 in the vertical direction.
[0075] 9, in this embodiment, the bottom surface 40a of the first recess 4a is parallel to the flat surface 33. In addition, the bottom surface 50a of the first drainage groove portion 5a is parallel to the flat surface 33 of the first lid 3a. Similarly, the bottom surface 40b of the second recess 4b and the bottom surface 50b of the second drainage groove portion 5b are parallel to the flat surface 33 of the second lid 3b.
[0076] In the container 1 of this embodiment, for example, as shown in Fig. 10, when the container body 2 is folded, the lids 3a and 3b are arranged so that the overlapping portion 34 of the first lid 3a rests on the overlapping portion 34 of the second lid 3b, thereby closing 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 abuts against the side wall 23 (specifically, the first side wall 24) of the container body 2 in the folded state, and the upper surface of the second lid 3b is inclined downward in the front with respect to the horizontal plane. With the overlapping portion 34 of the first lid 3a resting on the overlapping portion 34 of the second lid 3b, the upper surface of the first lid 3a is inclined downward in the rear with respect to the horizontal plane.
[0077] The overlapping portion 34 of the second lid 3b may be placed 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 abuts against the first side wall 24 of the container body 2 in the folded state, and the top surface of the first lid 3a is tilted downward toward the rear with respect to the horizontal plane. With respect to the second lid 3b, the overlapping portion 34 of the second lid 3b is placed on the overlapping portion 34 of the first lid 3a, and therefore the top surface of the second lid 3b is tilted downward toward the front with respect to the horizontal plane.
[0078] As a result, in the container 1 of this embodiment, rainwater received on the upper surfaces of the lids 3a, 3b can flow in a direction away from the overlapping portion 34 of the lids 3a, 3b. 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 drainage groove portions 5a, 5b while collecting at the outer ends of the bottom surfaces 40a, 40b in the front-to-rear direction. At this time, the wall surfaces of the outer ends of the recesses 4a, 4b in the front-to-rear direction prevent the rainwater from climbing over the recesses 4a, 4b and reaching the connecting portion 31. In addition, the wall surfaces of the outer ends of the recesses 4a, 4b in the left-to-right direction prevent the rainwater from climbing over the recesses 4a, 4b and reaching the fitting hole 32.
[0079] Therefore, in the container 1 of embodiment 2, drainage can be performed by avoiding the connecting portion 31, the fitting hole 32, and the overlapping portion 34 of the lids 3a and 3b, and rainwater can be prevented from entering the container 1.
[0080] The container 1 of the second embodiment described above can also employ appropriate modifications similar to those of the container 1 of the first embodiment.
[0081] In addition, 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).
[0082] Furthermore, the tilting means 9 does not have to be the reinforcing rib groups 6a, 6b, but may be, for example, constituted by a protrusion provided on the first side wall 24, or may be constituted by a dedicated member provided separately from the lids 3a, 3b and the first side wall 24.
[0083] Furthermore, the upper surfaces of the lids 3a, 3b do not need to have the recesses 4a, 4b and the drainage grooves 5a, 5b, and may be provided as a flat surface.
[0084] Similarly to the recesses 4a and 4b in the first embodiment, the bottom surfaces 40a and 40b of the recesses 4a and 4b may be surfaces that slope downward toward the outer periphery of the lids 3a and 3b.
[0085] (summary) As in the above-described first embodiment and its modified examples, the container 1 of the first aspect has the following configuration.
[0086] That is, the container 1 of the first embodiment comprises a box-shaped container body 2 having an opening 20 on its upper surface, and a lid 3 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. A bottom surface 40 of the recess 4 slopes downward toward the outer periphery of the lid 3.
[0087] In the container 1 of the first embodiment having the above configuration, when water is received on the bottom surface 40 of the recess 4 of the lid 3 during rainfall or the like, the inclination of the bottom surface 40 allows this water to flow toward the outer periphery of the lid 3. Therefore, in the container 1 of the first embodiment, the inclination of the bottom surface 40 of the recess 4 can regulate the flow direction of the water received on the upper surface of the lid 3, making it easy to suppress the intrusion of water into the container 1.
[0088] As in the above-mentioned first embodiment and its modified example, the container 1 of the second embodiment additionally comprises the following configuration in addition to the configuration of the container 1 of the first embodiment.
[0089] That is, in the container 1 of the second 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. The recess 4 includes a first recess 4a located on the upper surface of the first lid 3a and a second recess 4b located on the upper surface of the second lid 3b. The bottom surface 40a of the first recess 4a is inclined downward toward the opposite side to the second lid 3b. The bottom surface 40b of the second recess 4b is inclined downward toward the opposite side to the first lid 3a.
[0090] In the container 1 of the second embodiment having the above configuration, water received on the bottom surface 40a of the first recess 4a of the first lid 3a can flow in a direction away from the second lid 3b, and water received on the bottom surface 40b of the second recess 4b of the second lid 3b can flow in a direction away from the first lid 3a. This makes it easier to prevent water from entering the container 1 through the gap between the first lid 3a and the second lid 3b.
[0091] As in the above-mentioned first embodiment and its modified example, the container 1 of the third embodiment additionally comprises the following configuration in addition to the configuration of the container 1 of the second embodiment.
[0092] That is, in the container 1 of the third embodiment, the upper surface of the first lid 3a has a first drainage groove portion 5a that connects a part of the outer periphery of the first lid 3a to the first recess 4a. The upper surface of the second lid 3b has a second drainage groove portion 5b that connects a part of the outer periphery of the second lid 3b to the second recess 4b. The first drainage groove portion 5a is located at the end of the first lid 3a opposite to the second lid 3b. The second drainage groove portion 5b is located at the end of the second lid 3b opposite to the first lid 3a.
[0093] In the container 1 of the third embodiment having the above configuration, water that flows along the bottom surface 40a of the first recess 4a of the first lid 3a to the end opposite the second lid 3b can be drained to the outer periphery of the first lid 3a via the first drain groove portion 5a. In addition, in the container 1 of the third embodiment, water that flows along the bottom surface 40b of the second recess 4b of the second lid 3b to the end opposite the first lid 3a can be drained to the outer periphery of the second lid 3b via the second drain groove portion 5b. This makes it possible to prevent the water flowing along the bottom surfaces 40a, 40b of the recesses 4a, 4b of the lids 3a, 3b from overcoming the recesses 4a, 4b and being drained in an unintended direction.
[0094] As in the above-mentioned first embodiment and its modified examples, the container 1 of the fourth aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the second or third aspect.
[0095] That is, in the container 1 of the fourth embodiment, the first lid 3a has a first set of reinforcing ribs 6a that extend along the end portion adjacent to the second lid 3b and protrude downward. The second lid 3b has a second set of reinforcing ribs 6b that extend along the end portion adjacent to the first lid 3a and protrude downward.
[0096] With the above configuration, in the container 1 of the fourth embodiment, the reinforcing rib groups 6a, 6b can suppress bending of the lids 3a, 3b, respectively, and suppress a decrease in drainage caused by a change in the inclination of the bottom surfaces 40a, 40b of the recesses 4a, 4b of the lids 3a, 3b. Also, in the container 1 of the fourth embodiment, the reinforcing rib groups 6a, 6b protrude downward from the lids 3a, 3b, and are therefore less noticeable.
[0097] As in the above-mentioned second embodiment and its modified example, the container 1 of the fifth aspect has the following configuration.
[0098] That is, the container 1 of the fifth embodiment includes a box-shaped container body 2 having an opening 20 on its upper surface, a first lid 3a rotatably connected to the container body 2 so as to open and close a portion of the opening 20, and a second lid 3b rotatably connected to the container body 2 so as to open and close the remaining portion of the opening 20. The container 1 of the fifth embodiment further includes a tilting means 9 that tilts the first lid 3a and the second lid 3b in a state in which the opening 20 is closed. The tilting means 9 tilts the first lid 3a and the second lid 3b so that the upper surface of the first lid 3a is tilted downward toward the opposite side to the second lid 3b, and the upper surface of the second lid 3b is tilted downward toward the opposite side to the first lid 3a.
[0099] With the above configuration, in the container 1 of the fifth embodiment, the lids 3a, 3b can be tilted by the tilting means 9, which makes it easy to prevent water received on the upper surfaces of the lids 3a, 3b from entering the container 1 through the gap between the first lid 3a and the second lid 3b. In addition, in the container 1 of the fifth embodiment, the lids 3a, 3b can be tilted by the tilting means 9, so it is not necessary to manufacture the lids 3a, 3b so that their upper surfaces are inclined, which makes it easy to manufacture the lids 3a, 3b.
[0100] As in the above-mentioned second embodiment and its modified example, the container 1 of the sixth aspect additionally comprises the following configuration in addition to the configuration of the container 1 of the fifth aspect.
[0101] That is, in the container 1 of the sixth embodiment, the container body 2 has a foldable side wall 23. The first lid 3a has a first reinforcing rib group 6a that extends along the end portion 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 portion on the side adjacent to the first lid 3a and protrudes downward. The tilting 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 of the container body 2 in the folded state, thereby tilting the first lid 3a and the second lid 3b.
[0102] With the above configuration, in the container 1 of the sixth embodiment, it is not necessary to provide a member constituting the tilting means 9 separately from the lids 3a, 3b, and it is possible to suppress an increase in the number of parts of the container 1. Also, in the container 1 of the sixth embodiment, the reinforcing rib groups 6a, 6b can suppress bending of the lids 3a, 3b, respectively, and it is possible to suppress a decrease in drainage performance due to a change in the inclination of the upper surfaces of the lids 3a, 3b in the tilted state by the tilting means 9.
[0103] The present disclosure has been described above based on the embodiments shown in the attached drawings, but the present disclosure is not limited to the above embodiments, and appropriate design changes are possible within the intended scope of the present disclosure.
