Japanese Utility Model Publication No. 58-31668 Japanese Utility Model Publication No. 58-49945

  By the way, in the container with a lid of Patent Document 1, the lid member is rotated and displaced by about 270 degrees from the state where the opening of the container body is closed, and the lid member is aligned along the outer surface of the side wall portion of the container body. It is configured to be configurable. When the structure is employed, the outer surface of the side wall portion to which the lid member is coupled is covered with the lid member in a state where the opening of the container body is opened. For this reason, when the information display area which displays the information regarding the articles etc. which are accommodated is provided in the outer surface of the side wall part, the visible range is limited in the information display area. It will be impossible. Therefore, there is a concern that in the state where the opening of the container body is opened, troubles such as troublesome time for confirmation of information in the information display area may be caused.

  Also, for example, when the height of the side wall portion of the container main body is low, when the lid member is opened, the installation surface of the container main body is in a stage before the lid member is juxtaposed on the outer surface of the side wall portion of the container main body. There is concern about contact with the floor. In this case, there is a concern that the possibility of the tip portion of the lid member etc. being deformed / damaged is greatly increased, and in the case of deformation or the like, the container with the lid in a state where the container body is closed is sealed. There is a risk of lowering the property.

  On the other hand, the container with a lid of patent document 2 is comprised so that a lid | cover member can be hold | maintained in the attitude | position extended substantially perpendicularly with respect to the side wall part of a container main body. By adopting this configuration, the information display area can be visually recognized even when the opening of the container main body is opened, and even when the lid member is attached to the container main body having a low side wall portion height. When the lid member is opened, a situation in which the lid member contacts the floor surface can be avoided.

  However, when the article is stored in or taken out from the container body, the work space above the container body is greatly limited by the presence of the lid member extending substantially vertically from the upper side of the side wall part, There is concern that workability will be reduced. In particular, when storing articles using a robot, etc., the robot arm is forced to perform more severe operation control such as adjusting the orientation and suppressing vibration so that it does not touch the lid member. There is a concern that it may lead to a decrease in performance and an increase in costs related to equipment such as robots.

  The present invention has been made to solve the above-described problems and the like, and its purpose is to ensure the visibility of the information display area in a state in which the opening of the container body is opened and to accommodate articles. An object of the present invention is to provide a lidded container capable of improving workability.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A substantially rectangular plate-shaped bottom wall constituent part, and a side wall part extending upward from each side part of the bottom wall constituent part, and a substantially box-shaped container body opening upward,
A lid member that is pivotally attached to the upper side of the side wall and is displaceable between a closed position that closes the opening of the container body and an open position that opens the opening of the container body; In a lidded container comprising:
In one of the side wall part or the lid member, a shaft part for rotationally displacing the lid member with respect to the container body is provided,
In the other of the side wall part or the lid member, a bearing part that rotatably supports the shaft part is provided,
The lid member in the open position is held in a posture extending obliquely upward and outward with respect to the side wall portion,
The bearing portion is configured to allow rotational displacement of the shaft portion and sliding displacement of the shaft portion in a direction orthogonal to the rotation axis direction of the shaft portion;
The lid member is configured such that the relative position between the center of the shaft portion and the bearing portion is different between when the lid member is in the open position and when the lid member is in the closed position. container.

  According to the means 1, when the lid member is in the open position, the lid member is held in a posture that extends obliquely upward and outward. For this reason, even if an information display area for displaying information about articles to be accommodated is provided on the outer surface of the side wall portion to which the lid member is attached, the information is displayed by the lid member in the open position. It is possible to avoid a situation where the region is covered and cannot be visually recognized. Therefore, the information display area can be reliably confirmed without closing the lid member, and the convenience can be improved.

  Further, even when the height of the container body is lower than the width in the centrifugal direction from the rotation axis of the lid member, the lid member can be prevented from contacting the floor surface when the lid member is in the open position. . For this reason, the lid member comes into contact with the floor surface and is deformed / damaged. As a result, the lid member is deformed or the like. The lid member can be attached to the container body having a low height without causing problems such as destabilization or the like when the containers with lids are stacked up and down (stacked). Therefore, if the shape and size of the opening of the container body are the same, the same lid member can be attached to the container body of different heights, improving the versatility of the lid member, reducing costs, etc. Can be achieved.

  Furthermore, since the lid member in the open position is inclined so as to open outward, for example, the lidded container is opened as compared to a configuration in which the lid member is held in a vertically extending position in the open position. The working space above the container main body when taking in and out articles can be expanded, and the approach to the opening of the container main body can be made relatively easy. Therefore, improvement in workability at the time of loading / unloading articles into / from the container body, simplification of operation control of the robot when a robot is used for the loading / unloading work, the article, operator, or robot arm It is possible to reduce the risk of contact with the lid member and damage of the article, the lid member, and the like.

  Moreover, according to this means 1, not only the shaft part can rotate (relatively) with respect to the bearing part, but also can slide (relatively) in a direction orthogonal to the rotation axis direction of the shaft part. The center of the shaft portion and the relative position of the bearing portion are different between when the lid member is in the open position and when it is in the closed position. For this reason, for example, compared with the case where a shaft part rotates in the same position (it is set as a pin fulcrum), the part to which load is applied in a bearing part can be distributed. Therefore, deformation or damage of the bearing portion can be suppressed, and durability of the bearing portion can be improved.

  Furthermore, the shaft part is configured to be rotatable and slidable with respect to the bearing part, so that the relative position between the center of the shaft part and the bearing part is as follows. When the container body is in a relative position where the opening of the container body can be reliably closed (without a gap), and the lid member is in the middle of rotational displacement, the container body and the lid member do not interfere with each other (the lidded container The position can be a relative position. Accordingly, the configuration of the shaft portion and the peripheral portion of the bearing portion can be designed relatively freely, and the lid member is sealed when the lid member is in the closed position while ensuring the smooth opening and closing operability of the lid member. Performance can be improved, and space saving can be achieved in the configuration of the periphery of the shaft portion and the bearing portion.

  Mean 2. The means 1 according to claim 1, wherein the center of gravity of the lid member is positioned on the outer side of the container body with respect to the center of the shaft portion in a state where the lid member extends vertically. Container with lid.

  According to the means 2, if the lid member in the closed position is opened until it extends vertically (about 90 degrees), the lid member is displaced to the open position by its own weight. The workability at the open position can be improved. In addition, it is possible to more reliably prevent the lid member in the open position from being inadvertently displaced to the closed position due to vibration or the like.

Means 3. The end part which is the lowest part of the lid member in the open position is
It is assumed that even if the lid member in the closed position is displaced to the open position side, the relative position between the center of the shaft portion and the bearing portion does not change when the lid member is in the closed position. In addition, the lid member is positioned above the end portion which is the lowermost part of the lid member at the virtual position where the lid member is rotationally displaced until the same angle as the lid member at the open position is reached. The lidded container according to the means 1 or 2 characterized.

  According to the means 3, the center of the shaft portion and the bearing portion are affected by the action of changing the relative position between the center of the shaft portion and the bearing portion when the lid member is in the closed position and when the lid member is in the open position. Compared with the case where the relative position of the lid member is rotated and displaced without changing the relative position, the lower end of the lid member in the open position (the boundary between the side surface and the upper surface of the lid member) is positioned upward (downward). Can be suppressed). For this reason, when the lid member is in the open position, the portion hidden by the lid member can be reduced among the outer surface of the side wall portion to which the lid member is attached, and the information display area is provided on the outer surface of the side wall portion. A wider area (up to the upper side) can be secured.

  Means 4. In the process in which the lid member in the closed position is displaced to the open position side, an assist means is provided for assisting the upward displacement of the shaft portion or the bearing portion in conjunction with the lid member. The lidded container according to any one of means 1 to 3, wherein the container is a lid.

  According to the means 4, the assisting means can displace the shaft part or the bearing part, which is linked to the lid member, upward, and as a result, the lid that is in the open position as in the means 3 described above. The end part which is the lowest part of the member can be positioned as high as possible. Therefore, when the lid member is in the open position, the portion hidden by the lid member on the outer surface of the side wall portion to which the lid member is attached can be reduced, and a wider information display area can be secured. The effects such as the above are more reliably exhibited. Moreover, the effect that the displacement to the upper direction of the cover member made into an open position can be performed more smoothly is also show | played.

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.

  As shown in FIGS. 11 and 12, when the lid member 3 is in the closed position (when the lidded container 1 is in the closed state), the lid member 3 includes the side wall portions 12 and 13 and the upper flange portion. 14 so that the longitudinal direction of the hinge block 4 extends vertically (the connecting portion 43 and the shaft portion 42 are aligned vertically), and the shaft portion 42 is positioned below the bearing portion 64. It has become. 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.

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, as shown in FIGS. 1 and 18, when the lid member 3 is in the open position, the lid member 3 extends obliquely upward and outward. Retained. For this reason, the information display area 17 provided on the outer surface of the long side wall portion 12 to which the lid member 3 is attached is covered with the lid member in the open position and cannot be visually recognized. It can be avoided. 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.

  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 is inclined so as to open to the outside, the lid-equipped container 1 can be compared with, for example, a configuration in which the lid member 3 is held in a posture extending vertically in the open position. The working space above the container main body 2 when an article is put in and out in the open state can be widened, and the approach to the opening of the container main 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, according to the present embodiment, the shaft portion 42 is supported not only to be rotatable with respect to the bearing portion 64 but also to be slidable in a direction (vertical direction) perpendicular to the rotation axis direction of the shaft portion 42. Thus, the relative position between the center of the shaft portion 42 and the bearing portion 64 is different between when the lid member 3 is in the open position and when it is in the closed position. For this reason, for example, compared with the case where the shaft portion 42 rotates at the same position (is used as a pin fulcrum), it is possible to disperse the portion of the bearing portion 64 where a load is applied. Therefore, deformation or damage of the bearing portion 64 can be suppressed, and durability of the bearing portion 64 can be improved.

  Further, since the shaft portion 42 is configured to be rotatable and slidable with respect to the bearing portion 64, the relative position between the center of the shaft portion 42 and the bearing portion 64 is set, and the lid member 3 is set to the closed position. In some cases, the container body 2 and the lid member 2 are placed in a relative position where the opening of the container body 2 can be reliably closed (without a gap), and the lid member 3 is in the middle of rotational displacement. 3 can be set to a relative position where they do not interfere with each other (unlike when the lidded container 1 is closed). Accordingly, the configuration of the peripheral portion of the shaft portion 42 and the bearing portion 64 can be designed relatively freely, and the lid when the lid member 3 is in the closed position while ensuring the smooth opening / closing operability of the lid member 3. It is possible to improve the hermeticity of the attached container 1 and to save the space of the configuration of the peripheral portion of the shaft portion 42 and the bearing portion 64.

  In the present embodiment, the lid member 3 is configured such that the center of gravity of the lid member 3 is positioned outside the container body 2 with respect to the center of the shaft portion 42 in a state where the lid member 3 is in a vertically extending posture. For this reason, if the lid member 3 in the closed position is opened until it extends vertically (about 90 degrees), the lid member 3 is displaced to the open position by its own weight. The workability at the open position can be improved. Furthermore, it is possible to more reliably prevent the lid member 3 in the open position from being inadvertently displaced to the closed position due to vibration or light contact. In particular, in the present embodiment, the hinge block 4 that protrudes from the lower surface of the lid member 3 and is attached to the lid member 3 so as not to be relatively displaceable is moved outward when the lid member 3 is in the open position. Since it inclines and protrudes outward rather than the upper flange part 14, this effect will be show | played more notably.

  In the present embodiment, when the lid member 3 in the closed position is displaced to the open position, the third flat surface portion 47 of the hinge block 4 abuts on the assist protrusion 66 and the hinge block 4 is centered on the abutting portion. Is configured to be rotationally displaced. As a result, the shaft portion 42 is slid upward, and the hinge block 4 as a whole is pulled up toward the upper edge of the bearing portion 64 as the shaft portion 42 is displaced upward. The amount of downward displacement on the 43 side is suppressed.

  Therefore, for example, the lower end of the lid member 3 in the open position is closed even if the lid member 3 in the closed position as shown in FIG. 11 is displaced to the open position side. It is assumed that the relative position between the center of the shaft portion 42 and the bearing portion 64 does not change (when the shaft portion 42 rotates at the same position), and the lid member 3 is in the open position. The lid member 3 is in a virtual position where it is rotationally displaced until the same angle as that of the member 3 (actually, the assist protrusion 66 is omitted and the lower wall portion 63 is not turned unless the lower wall portion 63 is shaved). It will be located above the end which is the lowest part. Thereby, when the lid member 3 is set to the open position, the portion hidden by the lid member 3 in the outer surface of the long side wall portion 12 to which the lid member 3 is attached can be reduced, and the long side The information display area 17 can be secured wider (up to the upper side) on the outer surface of the side wall portion 12.

  In addition, the body-side hinge block insertion portion 61 is provided with an assist protrusion 66 that assists in the upward displacement of the shaft portion 42 in the process in which the lid member 3 in the closed position is displaced toward the open position. Therefore, for example, compared to a configuration in which the assist protrusion 66 is omitted (when the hinge block 4 rotates around a portion in contact with the edge of the lower wall portion 63), the rotation center of the hinge block 4 is set upward. And it can be located in the axial part 42 side. Therefore, the hinge block 4 can be rotated more smoothly and the hinge block 4 can be held at a higher position. Further, the assist protrusion 66 can increase the rigidity of the distal end portion of the lower wall portion 63 that supports the hinge block 4 and the lid member 3 together with the bearing portion 64. Therefore, damage and deformation of the lower wall portion 63 can be suppressed, and the lid member 3 in the open position can be held more stably.

  In addition, it is not limited to the description content of the said embodiment, For example, you may implement as follows. Of course, other application examples and modification examples not illustrated below are also possible.

  (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.

  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) There is no particular limitation on the posture (extension angle) of the lid member 3 in the open position in the above embodiment, and the lid member 3 is obliquely extended upward and outward. What is necessary is just to be comprised so that it may be hold | maintained.

  (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.

Moreover, in the said embodiment, although the hinge block 4 (the 1st plane part 45 and the 2nd plane part 46) and the positioning fixing | fixed part 54 are comprised in the structure which can contact | abut in planes, especially in such a structure. The hinge block 4 may be configured so as not to be relatively displaceable with respect to the lid member 3, including the configuration of connection between the connecting portion 43 and the connected portion 53. For example, the connecting part 43 and the connected part 53 may have a cross-sectional angular shape, and the connecting part 43 and the connected part 53 may be connected non-rotatably, or may be fixed with screws, bolts, etc. Instead of contacting each other, a plurality of protrusions and a flat surface may be contacted. However, as in the above-described embodiment, by providing the positioning fixing portion 54 that can abut on the hinge block 4 on two surfaces separately from the connecting portion 43 and the connected portion 53, the connecting portion 43 and the connected portion 53 are provided. The structure can be simplified, the durability of the connecting portion 43 and the connected portion 53 can be improved, the mounting workability can be improved, the mounting state can be stabilized, and the effect of protecting the hinge block 4 can be improved. The shape or the like of the assist protrusion 66 is not particularly limited. For example, the assist protrusion 66 may be formed in a rib shape that connects the pair of receiving wall portions 62. Further, the assist protrusion 66 can be omitted.

  (F) In the above-described embodiment, the container body 2 cannot be folded. However, the container body 2 can be applied to a container with a lid that can be folded. For example, the container body includes a substantially rectangular plate-shaped bottom wall constituent part, a side wall part extending upward from each side part of the bottom wall constituent part, and a square frame provided along the upper side part of the side wall part A side wall, the lower side is pivotally connected to the side of the bottom wall component, and the upper side is pivotable with respect to the upper frame. A pair of opposed first side walls including a top wall connected to the lower side of the lower wall so as to be rotatable with respect to the upper side of the lower wall, and the upper side to the upper frame A pair of opposed second side walls connected in a rotatable manner, and the second side wall is rotated and displaced inward from the assembled state assembled in a box shape, and the outer surface and the upper wall of the lower wall The first side wall and the second side wall are folded above the bottom wall component by folding the first side wall inward so as to match the outer surface of the part. Folding can be a state for facing the pair of side portions of the upper frame, as in the above embodiment, through a hinge block 4, it may be configured to connect the lid member 3.

  In the above embodiment, the pair of lid members 3 are opened and closed at the same time, but may be configured to be opened and closed one by one (the order in which one of the pair of lid members 3 overlaps the other is opened). Or a configuration that can be opened from either side). However, as in the above embodiment, the pair of lid members 3 are overlapped so as to cross each other, so that they can support each other on the distal end side of the lid member 3 and suppress drooping, rattling (raising), etc. When the lid member 3 is relatively heavier than the container main body 2, the lidded container 1 becomes unstable as in the case where only one lid member 3 is displaced to the open position. Such a situation can be avoided.

  Further, the shape, number, and mounting position of the lid member 3 are not limited. For example, in the above embodiment, the lid member 3 is attached to the long side wall portion 12, but may be attached to the short side wall portion 13. In addition, for example, a single cover member 3 that can close the entire opening of the container body 2 may be provided, or the opening of the container body 2 may be closed by three or more cover members 3. May be.

  In addition, in the said embodiment, although it has comprised so that the containers 1 with a lid can be stacked by making the cover member 3 into a closed position, the container 1 with a lid which cannot be stacked is also possible. It is also possible to embody.

  (G) In the above embodiment, the information display area 17 is configured such that a sticker on which information is printed is attached. However, the information display method in the information display area 17 is not particularly limited. However, it is possible to appropriately change such as attaching a card, directly printing and engraving, and attaching an IC tag. Further, for example, a card holder that allows the card to be detachably attached to the information display area 17 may be configured to be attachable. The position and size of the information display area 17 are not particularly limited, but are desirably provided on the outer surfaces of the side walls 12 and 13 in order to improve convenience. It is desirable that it is provided in a wide range as much as possible in order to improve easiness.

  (H) In the above embodiment, the container body 2, the lid member 3, and the hinge block 4 are made of polypropylene, but may be made of other resin materials such as polyethylene, PET, and polyamide.
