  By the way, the container main body of the container with a lid of patent document 1 is intermittently provided with a plurality of cylindrical portions extending in the lateral width direction of the long side wall portion so as to protrude upward from the upper side portion of the long side wall portion. The lid member is intermittently provided with a plurality of cylindrical portions extending along the side portions of the lid member so as to protrude laterally from the side portions of the lid member. The lid member is attached to the container body so as to be openable and closable by passing the elongated mandrel through the hole of the cylindrical part and the hole of the cylindrical part. For this reason, when attaching a lid member to a container main body, a mandrel is made into a plurality of cylindrical parts, and a plurality There is a concern that it will be a relatively time-consuming operation.

  On the other hand, the lidded container of Patent Document 2 is rotatably connected to the main body side pivoting portion that is rotatably connected to the main body side pivot support portion of the container main body and the lid side pivot support portion of the lid member. The lid part is provided with a hinge part having a lid-side axis attachment portion, and the lid member is configured to be rotatable with respect to the container body at two central axes. For this reason, in a state where the opening of the container body is closed, the hinge part protrudes upward from the side wall part, and the lid member is laid from the upper part of the hinge part toward the upper part of the opening of the container body. While closing an opening part, a hinge part can be stored in the range of the thickness of a side wall part. On the other hand, in the state where the opening of the container main body is opened, the hinge part is tilted outward to project outward from the side wall, and the lid member is suspended from the part projecting outward of the hinge part, The lid member is configured to be juxtaposed along the outer surface of the side wall portion of the container body.

  In addition, the attachment of the lid member to the container body only requires that the main body side pivot part and the lid side pivot part of each hinge part are connected to the main body side pivot part and the lid side pivot part, respectively. For example, the mounting workability can be improved as compared with a configuration in which a plurality of cylindrical portions and a plurality of cylindrical portions are aligned and the mandrel is penetrated as in Patent Document 1 described above.

  However, since the lid member is configured to be rotatable and displaceable in two axes with respect to the container body, the opening / closing operation of the lid member is complicated and awkward, and there is a concern that the opening / closing operability may be reduced.

FIG.

  The main body side hinge block insertion portion 61 is provided with a bearing portion 64 that rotatably supports the shaft portion 42 provided on the hinge block 4 in the pair of receiving wall portions 62. The bearing part 64 of this embodiment is comprised by the long hole up and down (refer FIG. 11). Thus, the shaft portion 42 is supported by the bearing portion 64 so as to be rotatable and slidable in the vertical direction.

  In addition, the lower part of the bearing part 64 is formed in circular arc shape. On the other hand, a portion of the upper flange portion 14 located above the bearing portion 64 is cut away, and a hole formed in the receiving wall portion 62 as the bearing portion 64 opens upward. For this reason, the shaft portion 42 of this embodiment extends through the receiving wall portion 62 to a position below the upper flange portion 14. In addition, the lateral width of the bearing portion 64 of this embodiment is slightly larger than the diameter of the shaft portion 42, and the vertical width of the bearing portion 64 (the distance from the lower portion of the bearing portion 64 to the lower surface of the upper flange portion 14) is The diameter of the portion 42 is about twice.

Further, the main body side hinge block insertion portion 61 is provided with two rows of protrusions 65 protruding from the outer surface of the long side wall portion 12 and extending vertically (see FIG. 5), and the lid member 3 is in the closed position. In this case, the second flat surface portion 46 of the hinge block 4 and the protrusion 65 are configured to contact or approach each other. For this reason, even when a force (downward force) that allows the lid member 3 in the closed position to enter the opening of the container body 2 is applied, the protrusion 65 hits the hinge block 4. Since the displacement that causes the hinge block 4 to fall inward is restricted, the downward displacement / deformation of the lid member 3 is suppressed.

  In addition, when the container 1 with a lid | cover is in a closed state, the lower surface of the site | part located outside the axial part 42 among the lid members 3 contact | abuts the upper surface of the upper flange part 14, or the position of the lid member 3 The slip prevention rib 35 is substantially in contact with the inner surface of the long side wall portion 12. For this reason, when displacing the lid member 3 in the closed position to the open position side, there is a concern that the lid member 3 does not lift or is difficult to lift. In this respect, in the present embodiment, since the shaft portion 42 is supported so as to be vertically displaceable with respect to the bearing portion 64, the lid member 3 can be operated only by opening the lid member 3. After sliding up to the position to be avoided, it is smoothly rotated and displaced toward the open position.

  Further, as shown in FIG. 5 and the like, each main body side hinge block insertion portion 61 is adjacent to the outer edge of the lower wall portion 63 on the upper surface of the lower wall portion 63 and has a lateral width of the lower wall portion 63. An assist protrusion 66 is provided as assist means that protrudes upward from a position including the central portion in the direction. As shown in FIG. 12, in the present embodiment, when the lid member 3 is in the closed position, the lower portion of the hinge block 4 and the lower wall portion 63 of the main body side hinge block insertion portion 61 are substantially in contact with each other. With the displacement of the lid member 3 in the closed position to the open position side, as shown in FIGS. 13 and 14, when the hinge block 4 is pivoted and displaced so as to fall outward (open outward), A side surface of the hinge block 4 (a third plane portion 47 which is a plane opposite to the second plane portion 46) is configured to contact the assist protrusion 66.

  Furthermore, in the present embodiment, since the bearing portion 64 is configured by a vertically long hole, even after the third flat portion 47 of the hinge block 4 and the assist protrusion 66 come into contact with each other, FIG. As shown, the hinge block 4 and the lid member 3 can be rotationally displaced outward with the contact portion as the center. At this time, the shaft part 42 rises, and the end part of the lid member 3 connected to the connecting part 43 and thus the connecting part 43 is lowered. 17 and 18, when the shaft portion 42 contacts the upper edge portion of the bearing portion 64 (the lower surface of the upper flange portion 14), further rotational displacement of the hinge block 4 is restricted. Is done. Further, when the rotational displacement of the hinge block 4 is restricted, the hinge block 4 is inclined downward and the lid member 3 extends obliquely upward and outward. It has come to be. For this reason, even if the hand is released from the lid member 3, the lid member 3 is held in its posture (open position).

  Further, in the present embodiment, as shown in FIGS. 15 and 16, the center of gravity of the lid member 3 is positioned outside the container body 2 from the center of the shaft portion 42 in a state where the lid member 3 is in a vertically extending posture. Is configured to do. Further, the hinge block 4 comes into contact with the assist protrusion 66 only at a portion closer to the shaft portion 42 than the central portion in the longitudinal direction. In addition, the positioning and fixing portion 54 is configured to abut on or be close to the first flat surface portion 45 of the hinge block 4 and a portion of the second flat surface portion 46 on the connecting portion 43 side. As a result, the first flat portion 45 of the hinge block 4 and the portion of the second flat portion 46 on the connecting portion 43 side are configured to be covered. That is, as shown in FIG. 12, when the lid member 3 is in the closed position, the upper portions of the first flat portion 45 that is the upper surface of the hinge block 4 and the second flat portion 46 that is the inner surface are covered. As shown in FIG. 18, when the lid member 3 is in the open position, the outer portions of the first plane portion 45 that is the outer surface of the hinge block 4 and the second plane portion 46 that is the upper surface are covered. It has become.

  Also, as shown in FIGS. 1 and 2, a card is affixed to the outer surface of each long side wall portion 12 and each short side wall portion 13 or is directly printed / engraved. For example, an information display area 17 is provided for displaying information related to articles to be stored. The formation range of the information display area 17 provided in the long side wall portion 12 is such that the long side wall portion 12 has a region from the lower position of the left main body side hinge block insertion portion 61 in the width direction of the long side wall portion 12. The position extends to a position slightly to the right of the center portion, and extends from the lower wall portion 63 to the lower flange portion 15 of the main body side hinge block insertion portion 61 in the height direction of the long side wall portion 12.

  In addition, the hinge block 4 of this embodiment is configured to be detachable from the container body 2 and the lid member 3. Then, by removing the hinge block 4 from the container main body 2, there are no portions protruding above the upper side portions of the side wall portions 12 and 13 of the container main body 2 and the upper flange portion 14. Thereby, only the container main body 2 can be suitably stacked now by container main bodies 2 mutually. In the stacked state of the container body 2, the lower flange portion 15 of the upper container body 2 is supported by the upper flange portion 14 and the upper sides of the side wall portions 12 and 13 of the lower container body 2, and The support rib 22 of the container body 2 is inserted into the inner peripheral side of the side wall portions 12 and 13 of the lower container body 2.

  As described above in detail, according to the present embodiment, the shaft portion 42 provided on the hinge block 4 attached so as not to be relatively displaceable with respect to the lid member 3 is replaced with the main body side hinge provided on the container main body 2. By connecting to the bearing part 64 of the block insertion part 61, the cover member 3 can be attached to the container main body 2 so that rotation is possible. For this reason, for example, a cylindrical portion extending in the lateral width direction of the long side wall portion so as to protrude upward from the upper side portion of the long side wall portion of the container main body, and a lateral side portion from the side portion of the lid member. By aligning the cylindrical portion extending along the side portion of the lid member so as to protrude, and passing the elongated mandrel through the cylindrical portion and the cylindrical portion, the lid member is attached to the container body. Compared with a configuration in which the lid member 3 can be freely opened and closed, the workability of attaching the lid member 3 can be improved.

  The hinge block 4 is provided so as not to be relatively displaceable with respect to the lid member 3, and is connected to the main body side hinge block insertion portion 61 provided on the long side wall portion 12 via the shaft portion 42 and the bearing portion 64. And are pivotally connected. For this reason, for example, compared with the case where the hinge block 4 is connected to the lid member 3 so as to be rotatable (when the lid member 3 can be rotationally displaced in two axes with respect to the container body 2). The opening and closing operation of the member 3 can be made simple and smooth. Therefore, the opening / closing operability of the lid member 3 can be improved.

  Further, the hinge block 4 is configured as a separate part from the container body 2 and the lid member 3 and is configured to be detachable from the container body 2 and the lid member 3. For this reason, compared with the case where the hinge block 4 is formed integrally with the container main body 2 or the lid member 3, for example, complication of the configuration (molding mold) of the container main body 2 or the lid member 3 is suppressed. be able to. Further, by removing the hinge block 4 from the container body 2 and the lid member 3, the container bodies 2 can be stacked only by the container body 2, or only the lid member 3 can be stored together (the lid members 3 are stepped together). Can be stacked). In this case, for example, the storage efficiency is improved (in a stacked state) as compared with a case where the hinge block 4 protrudes from the container body 2 or the hinge block 4 protrudes from the lid member 3 and is stored together. (Suppressing the height of a certain container body 2), stabilizing the stacked state of the container bodies 2, and preventing deformation and damage of the hinge block 4 can be achieved.

  Further, the lid member 3 provided with the hinge block 4 so as not to be relatively displaceable is also provided with a lid-side hinge block insertion portion 51 into which a portion of the hinge block 4 on the connecting portion 43 side is inserted. The attachment state of the hinge block 4 to the member 3 can be stabilized.

  In addition, as a structure for attaching the hinge block 4 to the lid member 3, a connected portion 53 connected to the connecting portion 43 of the hinge block 4 and a positioning fixing portion 54 that prevents relative displacement of the hinge block 4 are provided. Yes. Therefore, the connected portion 53 can be configured to prevent the hinge block 4 from falling off, the structure of the connecting portion 43 and the connected portion 53 can be simplified, and the lid member 3 can be connected to the hinge block. The workability when mounting 4 can be improved. Furthermore, for example, compared to the configuration in which the relative displacement between the lid member 3 and the hinge block 4 is prevented only by the connection between the connecting portion 43 and the connected portion 53, the connecting portion 43 and the connected portion 53. It is possible to improve the durability. Further, in order to make the relative displacement of the lid member 3 and the hinge block 4 impossible, the lid member 3 is attached as compared with a case where the lid member 3 and the hinge block 4 are bonded to each other or fixed by connecting means such as screws. The workability can be improved.

  Further, according to the present embodiment, as shown in FIGS. 1 and 18, when the lid member 3 is in the open position, the lid member 3 is held in a posture that extends obliquely upward and outward. For this reason, even when the information display area 17 is provided on the outer surface of the long side wall portion 12 to which the lid member 3 is attached, the information display area 17 is covered by the lid member 3 in the open position. It is possible to avoid a situation in which the user cannot be visually recognized. Therefore, even if the lid member 3 is not closed, the information display area 17 can be surely confirmed, and the convenience can be improved.

  Further, even when the height of the container body 2 is lower than the width of the lid member 3 in the centrifugal direction from the rotation axis, the lid member 3 is prevented from contacting the floor surface when the lid member 3 is in the open position. can do. For this reason, the lid member 3 comes into contact with the floor surface and is deformed / damaged. As a result, the lid member 3 is deformed and the like. In addition, the lid member 3 can be attached to the container body 2 having a low height without causing problems such as destabilization when the closed lidded containers 1 are stacked. Therefore, if the shape and size of the opening of the container body 2 are the same, the same lid member 3 can be attached to the container body 2 having different heights, and the versatility of the lid member 3 is improved. Costs can be reduced.

  Furthermore, since the lid member 3 in the open position extends obliquely upward and outward, for example, the article with the lid 1 in the open state compared to a configuration in which the lid member 3 extends upward and vertically in the open position. The working space above the container body 2 when taking out and in can be expanded, and the approach to the opening of the container body 2 can be made relatively easy. Therefore, improvement in workability at the time of loading / unloading articles into / from the container body 2, simplification of operation control of the robot when a robot is used for the loading / unloading work, articles, workers, or robot arms during the loading / unloading work Can come into contact with the lid member 3 to reduce the risk of damage to the article, the lid member 3 and the like.

  Further, when the lid member 3 is set to the open position, the positioning fixing portion 54 is configured to cover at least a part of the outer surface (first flat portion 45) and the upper surface (second flat portion 46) of the hinge block 4. Has been. For this reason, when performing the operation | work which accommodates articles | goods in the container 1 with a lid | cover, the situation where an article, another container, etc. contact the hinge block 4 etc. will damage the hinge block 4 grade | etc., Is suppressed. be able to. Further, even in the state where the lid member 3 is in the closed position, the positioning fixing portion 54 covers the inner surface and a part of the upper surface of the hinge block 4, and other containers and the like come into contact with the hinge block 4 and the hinge. A situation in which the block 4 or the like is damaged can be suppressed.

  Further, the lid member 3 in the closed position overlaps the side walls 12 and 13 in the vertical direction, and the hinge block 4 cannot be relatively displaced to the lid member 3 so as to protrude downward from the lower surface of the lid member 3 in the closed position. Is provided. For this reason, when the cover member 3 is set to the open position, the hinge block 4 protrudes outward from the long side wall portion 12 so as to fall down. Thereby, the whole lid member 3 in the open position can be positioned outward from the long side wall portion 12, and the work space above the container body 2 when the article is taken in and out of the container body 2 is widened. be able to. Therefore, the approach to the opening of the container body 2 can be made easier, and the workability of putting in and out the article can be improved.

  Further, for example, when the hinge block 4 is provided so as not to be detachable from the container body 2, a portion protruding upward from the container body 2 is formed. If you try to use or stack the container bodies 2 together, the hinge block 4 is easily damaged, or the container bodies 2 cannot be stacked together. It is possible to avoid a situation in which the height of the plurality of container bodies 2 in the state of being increased. Therefore, it is possible to improve convenience when the container body 2 is used alone or the container body 2 is stored alone.

  (A) In the above embodiment, the shaft portion 42 is provided in the hinge block 4 and the bearing portion 64 is provided in the main body side hinge block insertion portion 61. For example, as shown in FIGS. The block 71 may be provided with a bearing portion 72 (an oblong concave portion), and the main body side hinge block insertion portion 73 may be provided with a shaft portion 74. Further, when the configuration is adopted, as shown in FIG. 20, when the lid member 75 is in the closed position, the shaft portion 74 is positioned relative to the upper portion of the bearing portion 72, as shown in FIGS. In addition, when the cover member 75 is displaced to the open position side, the shaft portion 74 is positioned relative to the lower portion of the bearing portion 72, that is, the bearing block 72 side of the hinge block 71 is raised. desirable. In this case, the end portion of the lid member 75 that is in the open position can be positioned as high as possible.

  (B) In the above embodiment, the hinge block 4 is connected to the lid member 3 so as not to be relatively displaceable, and is connected to the container body 2 so as to be rotatable (and slidable). The lid member 3 may be coupled to be rotatable (and slidable) and may be coupled to the container body 2 so as not to be relatively displaced. That is, for example, as shown in FIGS. 24 to 28, a long-hole-shaped bearing portion 83 that is long in the vertical direction with respect to the lid-side hinge block insertion portion 82 of the lid member 81 is provided, and the body-side hinge block insertion portion of the container main body 84 is provided. 85 is provided with a circular hole-like connected portion 86 and a positioning fixing portion 87 that abuts against the flat portion of the hinge block 4 to restrict relative displacement of the hinge block 4, and the hinge block 4 is the same as that of the above embodiment.

It may be configured.

  In addition, the hinge block 4 can be used for a plurality of types of containers 1 with lids, and depending on the attachment target, the member to which the hinge block 4 is attached so as not to be relatively displaceable, or the mounting direction (posture) of the hinge block 4 is different. Alternatively, a configuration may be provided in which an object to which the hinge block 4 is attached so as not to be relatively displaceable and a mark capable of grasping the attachment direction are provided.

  Further, the hinge block 4 may be formed integrally with the lid member 3 or the container body 2, but in that case, the configuration of the lid member 3 or the container body 2 is complicated, the risk of damage to the hinge block 4 is increased, and storage is performed. Since there is a concern that the efficiency may be lowered, it is desirable to configure as a separate body.

  (C) Further, in the above-described embodiment, when the lid member 3 is in the closed position, the lid member 3 is placed on the side walls 12 and 13 so that the hinge block 4 is positioned below the lid member 3. For example, when the lid member 3 is in the closed position, the lid member 3 is shaped so as to project from the inner surfaces of the side wall portions 12 and 13, and the hinge block 4 is configured as the lid member 3. You may comprise so that it may protrude to the side from the side surface. However, in view of the stability of the lid member 3 in the closed position and the expansion of the work space above the opening of the container body 2 when the lid member 3 is in the open position, as in the above embodiment, It is desirable to adopt a configuration in which the hinge block 4 protrudes downward from the lower surface of the lid member 3.

  When the hinge block 4 is connected to the long side wall portion 12 so as not to be relatively displaceable, the hinge block 4 obstructs the internal space of the container body 2 or reduces the storage efficiency of the lidded container 1. It is desirable that the hinge block 4 protrudes from the upper surface rather than protrudes from the inner surface or outer surface of the long side wall portion 12 in order to avoid the risk of damage or increase the risk of damage to the hinge block 4.

  (D) The position (extension angle) of the lid member 3 in the open position in the above embodiment is not particularly limited and can be set as appropriate. However, when the information display area 17 is provided on the outer surface of the long side wall portion 12 to which the lid member 3 is attached, the lid member 3 in the open position faces upward from the long side wall portion 12. It is desirable to be configured to be held in a posture that extends in the vertical direction or the cover member 3 extends obliquely upward and outward. Furthermore, it is desirable that the lid member 3 in the open position extends upward and outward in order to ensure the space above the opening of the container body 2 as wide as possible during the operation of loading and unloading articles into and from the container body 2. .

  (E) In the above embodiment, the bearing portion 64 is configured in an oval shape, but the bearing portion 64 may be any hole or recess that is larger than the shaft portion 42. For example, the shape of the bearing portion 64 may be a circular shape, a polygonal shape, or an oval shape that is long in the horizontal direction. However, in order to stabilize the holding state of the lid member 3 in the open position, it is desirable that the bearing portion 64 has a substantially oval shape with the shaft portion 42 as a roller fulcrum, and further, the lid member 3 is opened. It is desirable to be configured to extend in the vertical direction so that the lowest point of the lid member 3 can be displaced upward by setting the position.
