Description

[Technical Field]

[0001] The present invention relates to a container having a lid. [Background technology]

[0002] Conventionally, containers used as trash cans and the like have been known that include a box-shaped container body that opens upward, a pair of lid bodies that can open and close the opening of the container body, a pedal, and an interlocking member that links the pair of lid bodies to the operation of the pedal to open the opening of the container body (see, for example, Patent Document 1, etc.). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2019-85241 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, the container described in Patent Document 1 is configured such that when the opening of the container body is opened, the pair of lids are always displaced to the open position, opening the entire opening, regardless of the size, shape, etc. of the object (garbage) to be thrown into the container. In this regard, a structure that allows the lids to be opened and closed efficiently according to the size, etc. of the object to be thrown into the container is desired.

[0005] The present invention has been made to solve the problems exemplified above, and an object of the present invention is to provide a container that allows the lid to be opened and closed efficiently. [Means for solving the problem]

[0006] The following describes each means suitable for achieving the above objects, etc., by item. Note that, as necessary, the effects and advantages specific to the corresponding means will be added.

[0007] Means 1. A substantially box-shaped container body having an opening that opens upward, a first lid body that is rotatably displaceable relative to the container body between an open position that opens the opening and a closed position that closes the opening, and that is attached such that a first central axis that is the center of the rotational displacement extends along the periphery of the opening, The first lid body is a first lid body having a lid opening that exposes a portion of the opening when the first lid body is in the closed position; a second lid that is rotatably displaceable relative to the first lid body between an open position that opens the lid opening and a closed position that closes the lid opening, and that is attached such that a second central axis that is the center of rotational displacement extends in a direction parallel to the first central axis; When the second cover body is in the closed position and is set to the open position, a portion of the second cover body opposite to the second central axis is pivotally displaced upward, the second cover is configured to extend from the second central axis toward the first central axis when in the closed position, A container characterized in that the opening area of ​​the opening in a first open state in which the first lid body is in the open position is larger than the opening area of ​​the opening in a second open state in which the first lid body is in the closed position and the second lid body is in the open position.

[0008] According to the first method, the lid (the entire first lid including the second lid, or only the second lid) to be placed in the open position can be selected to ensure an opening shape (opening area) of the opening of the container body suitable for the insertion of the object (garbage) depending on the size, shape, etc. of the object (garbage) to be inserted into the container, and the selected lid can be placed in the open position. In particular, because the second lid is attached to the first lid, placing the first lid in the open position also displaces the second lid, opening the entire opening. In other words, whether the entire opening or a portion of the opening is to be opened, only one lid needs to be placed in the open position, thereby improving the workability and convenience of opening the opening. Furthermore, when only the second lid is opened or closed, the opening area of ​​the opening can be made smaller, and the time required to open and close the lid (and thus the time required to insert the object into the container) can be made relatively short compared to when the entire opening is opened and closed at the same time. Furthermore, it is possible to prevent adverse effects on objects stored in the container when the lid is opened or closed (for example, relatively light objects stored in the container being lifted up by wind generated when the lid is opened or closed).As a result, the lid can be selectively and efficiently opened or closed depending on the situation to achieve the desired usage, thereby improving convenience, etc.

[0009] Furthermore, by providing the second lid in the closed position so that it extends from the second central axis toward the first central axis, the rotation direction of the second lid for opening and closing can be opposite to the rotation direction of the first lid for opening and closing. That is, for example, when the first lid in the closed position is rotated approximately 90 degrees to the open position, the second lid rotates so that the second central axis side of the second lid is on the upper side in conjunction with the rotation of the first lid. This prevents a situation in which, for example, when the second lid in the closed position extends from the second central axis toward the opposite side from the first central axis, the second lid also rotates toward the open position relative to the first lid body and makes contact with the first lid body when returning to the closed position, thereby preventing abnormal noise. Furthermore, there is no need for a means for holding the second lid in the closed position (locking it to prevent relative displacement), which simplifies the configuration and improves operability when opening and closing the second lid.

[0010] Means 2. The second central axis is disposed in a central region among three regions obtained by dividing the first lid body into equal parts in a direction perpendicular to the extending direction of the first central axis, The container described in means 1 is characterized in that the edge portion of the second lid body opposite the second central axis side is positioned in the region on the side where the first central axis is located, among the three regions obtained by dividing the first lid body into three equal parts in a direction perpendicular to the extension direction of the first central axis.

[0011] According to the second aspect, when the container is in the second open state, the lid opening (opening) opens at a portion of the first lid closer to the first central axis. Therefore, when the container is primarily used in the second open state, the container can be placed with the first central axis facing the user, thereby further reducing the distance between the lid opening and the second lid and the user (allowing the user to insert an object into the container through the lid opening closer to the user). This facilitates opening and closing the second lid and also facilitates inserting an object into the container through the opening (lid opening) that opens when the container is in the second open state. Furthermore, while maintaining an appropriate opening area for the opening in the second open state, the height of the container when the second lid is rotated upward by approximately 90 degrees from the closed position is kept lower than the height of the container when the first lid is rotated upward by approximately 90 degrees from the open position, making it easier to install the container in places with height restrictions.

[0012] Means 3. A container described in means 1 or 2, characterized in that in the second open state, the second lid body is supported in contact with the first lid body in a position extending upward relative to the upper edge of the container body.

[0013] According to Means 3, for example, compared to a configuration in which the second lid body in the closed position is rotated and displaced by approximately 180 degrees, the operation for displacing the second lid body to the open position and the operation for displacing the second lid body in the open position to the closed position can be performed relatively easily. Also, in the second open state, the upper surface of the first lid body in the closed position can be used as a work table, and for example, a plurality of predetermined objects can be placed on the first lid body, and all or some of the objects can be stored one by one in order into the container (for example, storing the objects one by one in an organized manner, removing tags from the objects and storing the tags, etc.).

[0014] Means 4: The first cover body has a first operating part that is operated when opening and closing the first cover body, the second cover includes a second operating portion that is operated when opening and closing the second cover, the first operating portion is provided on a portion of the first cover body opposite to a side on which the first central axis is provided, The container described in means 1 or 2 is characterized in that the second operating part is arranged to be positioned in the part of the first lid body on the side where the first central axis is provided when the second lid body is in the closed position.

[0015] According to Means 4, by placing the container with the side opposite to the first central axis facing forward, the first cover can be opened and closed relatively easily by operating the first operating part. Also, by placing the container with the first central axis facing forward, the second cover can be opened and closed relatively easily by operating the second operating part.

[0016] Means 5. The container described in Means 4, characterized in that the first operating part is adjacent to a first side edge portion of the first lid body opposite the side edge portion on which the first central axis is provided, and is provided on one side of the first side edge portion and the second side edge portion at a position near the boundary between the first side edge portion and a second side edge portion extending in a direction intersecting the first side edge portion.

[0017] According to the fifth aspect, even when the container is placed with the first central axis side facing either the left or right side (with the second side edge facing forward), the first cover can be opened and closed relatively easily by operating the first operating part. Furthermore, compared to when the first operating parts are provided on both the first and second side edges of the first cover main body, the shape of the first cover main body can be simplified and the weight can be reduced.

[0019] An embodiment will be described below with reference to the drawings. As shown in Figures 1 to 3, etc., a container 1 includes a container body 2 having a substantially rectangular box shape, which includes a storage section 3 capable of storing objects (for example, garbage, etc.) and an opening 4 that opens upward, and a lid unit 5 that can close the opening 4 of the container body 2. As shown in Figures 2, 7, 13, etc., the lid unit 5 includes a lid mounting frame 6 that is attached to the container body 2 and has an insertion opening 7 through which an object can be inserted, and a first lid body 8 that is displaceable between an open position that opens the insertion opening 7 and, therefore, the opening 4 of the container body 2, and a closed position that closes the opening 4.

[0020] 6, the container body 2 includes a bottom wall 11 that is generally rectangular in plan view, a pair of opposing long sidewalls 12 extending upward from a pair of opposing long sides of the bottom wall 11, a pair of opposing short sidewalls 13 extending upward from a pair of opposing short sides of the bottom wall 11, a generally rectangular frame-shaped protrusion 14 that protrudes outward from the container body 2 from the entire upper edges of the long sidewalls 12 and the short sidewalls 13, and an edge wall 15 that protrudes upward from the entire outer edge of the protrusion 14. The long sidewalls 12 and the short sidewalls 13 of the container body 2 are configured in a tapered shape that is slightly inclined upward outward from the container body 2, and the opening 4 is rectangular in plan view of the container body 2.

[0021] Additionally, a roller mounting portion 17, to which a roller 16 is rotatably attached, is provided near one short side of the underside of the bottom wall portion 11. A relatively wide area of ​​the bottom wall portion 11, including its center, protrudes downward from the area where the roller mounting portion 17 is provided. As a result, when the container body 2 is placed on a mounting surface such as a floor, the downwardly protruding portion of the underside of the bottom wall portion 11 contacts the mounting surface while the roller 16 protrudes downward from the roller mounting portion 17, allowing the bottom wall portion 11 to extend substantially horizontally and preventing relative horizontal displacement of the container body 2. On the other hand, when moving the container 1, the container body 2 is held so that the short side of the container body 2 not provided with the roller 16 is slightly suspended in the air, allowing only the roller 16 to contact the mounting surface, thereby enabling relatively smooth horizontal movement of the container body 2. In this embodiment, the container body 2 and the roller 16 are integrally formed from polypropylene.

[0022] 7, 8, 11, etc., the lid mounting frame 6 includes a substantially rectangular frame body 21 that is located above the overhanging portion 14 of the container body 2 and in an area of ​​the container body 2 relative to the edge wall portion 15 when attached to the container body 2, frame support protrusions 22 that protrude outward from the upper edge of the frame body 21 and are supported by abutting against the upper edge of the edge wall portion 15 of the container body 2 when attached to the container body 2, and frame regulating protrusions 23 that protrude upward from the upper edge of the frame body 21. As shown in Fig. 7, the portions of the frame body 21 that correspond to the short sides form a stepped shape (crank-shaped cross section) with the lower side facing inward of the lid mounting frame 6 (inward of the container body 2) and the upper side facing outward of the lid mounting frame 6.

[0023] Furthermore, a first pivotal support portion 24 that supports the first lid body 8 so that it can be rotatably displaced is provided on one long side of the lid mounting frame 6. More specifically, notches are provided in the upper edge of the frame regulating protrusion 23 on the one long side of the lid mounting frame 6 in areas near both ends, and the first pivotal support portion 24 is configured by cylindrical protrusions that are connected to both ends and protrude above the notches.

[0024] 10 and other figures, this embodiment is configured to accommodate a bag stopper member 27 for holding the periphery of the opening of a bag (garbage bag) placed in the storage section 3 of the container body 2. The bag stopper member 27 has a rectangular frame shape and is arranged along the inner periphery of the frame body 21 of the lid mounting frame 6. The bag stopper member 27 is also provided with bag stopper support protrusions 28 that protrude outward from the upper portion of the outer surface of each short side of the bag stopper member 27 and are supported by abutting against stepped portions (upper surfaces) of each short side of the frame body 21 when the bag stopper member 27 is attached to the lid mounting frame 6. For example, a garbage bag is inserted into the bag stopper member 27, and the upper portion of the garbage bag is rotated upward and outward around the bag stopper member 27 so that it hangs downward. Then, the bag stopper member 27 is attached to the lid mounting frame 6 attached to the container body 2, whereby the garbage bag is fixed to the container body 2 in a manner that the garbage bag is sandwiched between the bag stopper member 27 and the lid mounting frame 6.

[0025] 4, 7, 8, 12, etc., the first lid body 8 includes a first lid body main body 31 having a lid body opening 32 that opens a portion of the input opening 7 (opening 4) when the first lid body 8 is in the closed position, and a second lid body 51 that is attached to the first lid body main body 31 so as to be rotatable between an open position where the lid body opening 32 is open and a closed position where the lid body opening 32 is closed. As shown in FIGS. 1, 7, etc., the outer peripheral shape of the first lid body main body 31 is rectangular in plan view, which roughly matches the outer peripheral shape of the lid mounting frame 6 when the first lid body 8 is in the closed position, and the entire opening 4 can be closed by placing the first lid body 8 in the closed position. 4, 7, 9, etc., when the first lid body main body 31 is viewed from above, the lid body opening 32 has a generally rectangular shape such that the longitudinal width direction of the first lid body 8 (first lid body main body 31) coincides with the longitudinal width direction of the lid body opening 32, and each side edge of the lid body opening 32 extends generally parallel to each side edge of the first lid body main body 31. The lid mounting frame 6, bag stopper member 27, first lid body main body 31, and second lid body 51 are each integrally formed from polypropylene.

[0026] As shown in FIGS. 7 and 8 , the first lid body main body 31 includes a substantially rectangular plate-shaped first base portion 33 in which a lid body opening 32 is formed, and a first lid outer peripheral rib 34 that protrudes downward from the outer peripheral edge of the underside of the first base portion 33. The first lid body main body 31 also includes a first shaft portion 35 that protrudes downward from a portion of the underside of the first base portion 33 near one of its long sides and is journaled by the first journal support portion 24. The first shaft portion 35 has a hole (or a recess) into which the first journal support portion 24 is inserted. By inserting the first journal support portion 24 into the hole or the like of the first shaft portion 35, the first lid body main body 31 is attached to the lid mounting frame 6 such that a first central axis 36 (see FIGS. 9 and 13 ), which serves as the center of rotational displacement of the first lid body 8 (first lid body main body 31), extends along the peripheral edge of the opening 4 (one of the long sides of the lid mounting frame 6). When the first lid body 8 is in the closed position, the lower surface of the first base 33 is supported by abutting against the upper edge of the frame restricting protrusion 23, the first lid outer periphery rib 34 is disposed in contact with or in close proximity to the outer surface of the frame restricting protrusion 23, and the upper surface of the first base 33 extends in a substantially horizontal direction (see FIG. 11 ). Furthermore, by rotating the first lid body 8 slightly more than 90 degrees (e.g., 91 degrees) from the closed position, the first lid outer periphery rib 34 (the portion corresponding to the long side of the first lid body main body 31 on which the first central axis 36 is provided) abuts against the outer surface of the frame restricting protrusion 23 (at a position before and after the cut position in FIG. 13 ). This restricts further displacement of the first lid body 8 toward the open position, and maintains the orientation of the first lid body 8 in the open position.

[0027] As shown in FIGS. 7 and 9 , the lid opening 32 extends from a position on the long side of the first base 33, where the first central axis 36 (first axis 35) is slightly further away from the center of the first base 33 in the short width direction, to a position near the first central axis 36, and extends from a position near one short side of the first base 33 to a position near the other short side of the first base 33 in the long width direction. However, as shown in FIGS. 7 and 8 , the first lid main body 31 includes a peripheral wall 37 that protrudes downward from the periphery of the lid opening 32 of the first base 33, and a lid support portion 38 that protrudes inward from the middle of the peripheral wall 37 in the vertical width direction toward the lid opening 32. Therefore, the substantial opening area of ​​the lid opening 32 is the range on the inner periphery of the lid support portion 38. The length of projection of the lid support portion 38 from the peripheral wall portion 37 is uniform for each side edge of the lid opening 32 .

[0028] 7, the first lid body main body 31 is provided with second pivotal support portions 39 that support the second lid body 51 in a rotatable manner, corresponding to the long side edge portions of the pair of long side edges of the lid body opening 32 that are on the opposite side to the first central axis 36 side (the side on which the first shaft portion 35 is provided). More specifically, the second pivotal support portions 39 are configured by making target portions of the peripheral wall portion 37 that correspond to the pair of short side edges of the lid body opening 32 protrude downward more than the other portions, and by providing holes (or recesses) in the pair of protruding portions, respectively. Furthermore, corresponding to the long side edge of the pair of long side edges of the lid opening 32 opposite the first central axis 36, a peripheral wall portion 37 and a lid support portion 38 are formed along the peripheral portion of the protruding portion for the second pivot support portion 39, and the peripheral wall portion 37 protrudes downward more than other portions of the peripheral wall portion 37, and the lid support portion 38 protrudes inward of the lid opening 32 more than other portions of the lid support portion 38 (the tip edge of the lid support portion 38 is located slightly closer to the first central axis 36 than the center of the first lid main body 31 in the short width direction).

[0029] 4, 7, etc., the first lid body 31 is provided with a restriction receiving portion 40 that is continuous with the lid support portion 38 by recessing the first base portion 33 to the same height as the lid support portion 38 in a range including the center of the long side portion on the first central axis 36 side. Furthermore, an operation receiving portion 41 is provided in correspondence with the restriction receiving portion 40, by recessing the long side portion of the first lid body 31 toward the inner periphery of the first lid body 31. Note that, as shown in FIG. 8, first reinforcing ribs 42 that protrude downward from the first base portion 33 and connect the first lid outer periphery rib 34 and the peripheral wall portion 37 are provided on the underside of the first lid body 31 corresponding to both sides of the restriction receiving portion 40.

[0030] 3, 7, 9, etc., the first lid body 31 is provided with a first operating part 43 that is operated when opening and closing the first lid body 8, at a portion of the first lid body 31 opposite to the side where the first central axis 36 (first axis portion 35) is provided. In this embodiment, the first operating part 43 is adjacent to a long side portion (first side edge portion) of the first lid body 31 opposite to the long side portion where the first central axis 36 is provided, and is provided in a position near the boundary with the first side edge portion on a short side portion (second side edge portion; in this example, the short side portion located counterclockwise with respect to the first side edge portion when the first lid body 31 is viewed in a plane) that extends in a direction intersecting the first side edge portion.

[0031] 7, 8, etc., the second cover 51 includes a second base 52 having a rectangular shape in a plan view, a restricting protrusion 53 having a rectangular shape in a plan view and protruding laterally from an area including the center of one of the long sides of the second base 52, and a second operating portion 54 protruding downward from a position near the tip edge of the restricting protrusion 53. A second cover outer peripheral rib 55 is provided on the underside of the second cover 51 (the second base 52 and the restricting protrusion 53) and protrudes downward from the outer peripheral edge thereof, and the second operating portion 54 is configured by making the second cover outer peripheral rib 55 protrude downward further than other portions. The second cover 51 also includes second shafts 56 pivotally supported by the second pivot support portions 39, corresponding to both ends of one of the pair of long sides of the second base 52 opposite the side on which the restricting protrusion 53 is provided. In this embodiment, the second shaft portion 56 is configured by making target portions of the second cover outer peripheral rib 55 corresponding to a pair of short sides of the second base portion 52 protrude downward more than the other portions, and by providing cylindrical protrusions that protrude from the pair of protruding portions toward the sides of the second cover body 51. By inserting the second shaft portion 56 into a hole or the like of the second pivot support portion 39, the second cover body 51 is attached to the first cover body main body 31 such that a second central axis 57, which is the center of rotational displacement of the second cover body 51, extends along the peripheral edge of the cover body opening portion 32 (the long side edge on the side farther from the first central axis 36) (see FIG. 9).

[0032] 11, when the container 1 is in a closed state with the first lid 8 (first lid main body 31) and the second lid 51 in the closed position, the lower edge of the second lid outer peripheral rib 55 of the second lid 51 abuts against and is supported by the lid support portion 38 of the first lid main body 31 and the upper surface of the restriction receiving portion 40. This restricts downward relative displacement of the second lid 51 in the closed position (maintaining the closed position in which it extends substantially parallel to the first lid main body 31). Furthermore, when the container 1 is in the closed state, the upper surface of the second lid 51 (second base portion 52 and restriction protrusion 53) and the upper surface of the first lid main body 31 (first base portion 33) are configured to be at substantially the same height (substantially flush).

[0033] 9, each side edge of the lid opening 32 extends parallel to each side edge of the first lid body 31, and the second central axis 57 of the second lid body 51 extends in a direction parallel to the first central axis 36 of the first lid body 31. In this embodiment, the second central axis 57 (second pivot support portion 39) is disposed in a central region (more specifically, approximately the center position in the short width direction of the first lid body 8) of each of three equal regions obtained by dividing the first lid body 8 in a direction perpendicular to the extension direction of the first central axis 36 (the short width direction of the first lid body 8).

[0034] Furthermore, the second central axis 57 extends along the long edge of the cover opening 32 that is farther from the first central axis 36, and the second cover 51 is configured to extend from the second central axis 57 toward the first central axis 36 when in the closed position. In addition, as shown in FIGS. 4, 5, and 12, when the second cover 51 is in the closed position and is changed to the open position, a portion of the second cover 51 opposite the second central axis 57 is configured to be pivoted upward. As shown in FIG. 11, in this embodiment, a second operating unit 54 is provided on the edge of the second cover 51 opposite the second central axis 57. The second operating unit 54 is disposed along the long side of the first cover main body 31 on the side where the first central axis 36 is provided when the second cover 51 is in the closed position, and is received by the operation receiving unit 41. A gap is formed between the lower edge of the second operating unit 54 and the cover mounting frame 6 so that a user can insert their fingertip. Therefore, when the second cover body 51, which is in the closed position, is to be moved to the open position, the second cover body 51 is displaced toward the open position by hooking a finger on the lower edge of the second operating part 54 and lifting it up.

[0035] 9 and other figures, the second cover 51, which can close the entire cover opening 32 located closer to the first central axis 36 in the short width direction of the first cover 8, has an edge portion of the second cover 51 opposite to the second central axis 57 (an edge portion of the restricting protrusion 53 and an edge portion of the second base 52 located on both sides of the restricting protrusion 53) that is disposed in the region on the first central axis 36 side of each of the regions obtained by dividing the first cover 8 into three equal parts in the direction perpendicular to the extension direction of the first central axis 36. In addition, as shown in FIG. 7, the second operating portion 54 is provided corresponding to the entire tip edge of the restricting protrusion 53.

[0036] 7, the second pivot support 39 (second central axis 57 of the second lid 51) provided on the first lid main body 31 is located below the lower surface of the first base 33, and as shown in FIG. 12, by rotating the second lid 51 from the closed position toward the open position by a little more than 90 degrees (for example, 97 degrees), the upper surface of the second base 52 comes into contact with (is supported by) the vicinity of the boundary between the peripheral wall 37 and the first base 33. This restricts further displacement of the second lid 51 toward the open position, and maintains the orientation of the second lid 51 in the open position (the orientation extending upward relative to the upper edge of the container main body 2).

[0037] As described above, the container 1 of this embodiment has two open state patterns for the first lid body 8 and the second lid body 51: a first open state (see FIGS. 2 and 13) in which the first lid body 8 is in the open position, and a second open state (see FIGS. 4 and 12) in which the first lid body 8 (first lid body main body 31) is in the closed position and the second lid body 51 is in the open position. That is, the second lid body 51 is configured to be displaced in conjunction with the displacement of the first lid body main body 31. When the first operating unit 43 is operated to displace the first lid body main body 31 toward the open position of the first lid body 8, the entire first lid body 8, including the second lid body 51, is displaced to the open position. Furthermore, the second lid body 51 is configured to be rotatable between the closed position and the open position by operating the second operating unit 54 without displacing the first lid body main body 31. 2, 12, etc., the lid opening 32 of the first lid 8 in the closed position is configured to be horizontally aligned over the entire area of ​​the opening 4 of the container body 2, and to have a smaller area than the opening 4. That is, in the second open state, the opening area of ​​the lid opening 32 is the same as the opening area of ​​the opening 4, and the opening area of ​​the opening 4 in the first open state is larger than the opening area of ​​the opening 4 in the second open state. For example, when using the container 1 as a trash can, the second open state is used when throwing objects such as empty bottles into the storage section 3, and the first open state is used when attaching or detaching trash bags, retrieving objects accidentally thrown into the storage section 3, or straightening out any unevenness of the stored objects.

[0038] As described above in detail, according to this embodiment, depending on the size, shape, etc. of the object (garbage) to be thrown into the container 1, a lid (the entire first lid 8 including the second lid 51, or only the second lid 51) to be placed in the open position can be selected to ensure an opening shape (opening area) of the opening 4 of the container body 2 that is suitable (minimum necessary) for throwing in the object, and the selected lid can be placed in the open position. In particular, because the second lid 51 is provided on the first lid 8, placing the first lid 8 (first lid body 31) in the open position also displaces the second lid 51, thereby opening the entire opening 4. In other words, whether the entire opening 4 or a portion of the opening 4 is to be opened, it is only necessary to place one lid in the open position, thereby improving the operability and convenience when opening the opening 4. Furthermore, when only the second lid 51 is opened and closed, the opening area of ​​the opening 4 can be made smaller and the time required to open and close the second lid 51 (and thus the time required to put an object into the container 1) can be made relatively short compared to when the entire opening 4 is opened and closed at once. Furthermore, it is possible to prevent adverse effects on objects contained in the container 1 when the lid is opened and closed (for example, relatively light objects contained in the container 1 being lifted up by wind generated when the lid is opened and closed). As a result, the lid can be opened and closed selectively and efficiently depending on the situation to achieve the desired usage, thereby improving convenience, etc.

[0039] Furthermore, by providing the second cover 51 in the closed position so as to extend from the second central axis 57 toward the first central axis 36, the rotation direction of the second cover 51 for opening and closing can be set opposite to the rotation direction of the first cover 8 for opening and closing. That is, for example, when the first cover 8 in the closed position is rotated approximately 90 degrees to the open position, the second cover 51 rotates so that the second central axis 57 side of the second cover 51 is on the upper side in conjunction with the rotation of the first cover 8. Therefore, for example, when the first cover 8 is rotated, such as when the second cover 51 in the closed position extends from the second central axis 57 toward the opposite side from the first central axis 36, the second cover 51 also rotates toward the open position relative to the first cover main body 31, and this can prevent a situation in which the second cover 51 comes into contact with the first cover main body 31 when returning to the closed position, causing abnormal noise. In addition, there is no need to provide a means for holding the second lid body 51 in the closed position (locking it to prevent relative displacement), which simplifies the configuration and improves operability when opening and closing the second lid body 51.

[0040] Furthermore, the second central axis 57 is disposed in a central region of each of the regions obtained by dividing the first lid body 8 into three equal parts in a direction perpendicular to the extension direction of the first central axis 36 (the short width direction of the first lid body 8). Furthermore, the edge of the second lid body 51 on the opposite side to the second central axis 57 is disposed in the region on the first central axis 36 side of each of the regions obtained by dividing the first lid body 8 into three equal parts in a direction perpendicular to the extension direction of the first central axis 36. Therefore, when the container 1 is in the second open state, the lid body opening 32 (opening 4) opens at a portion of the first lid body 8 on the first central axis 36 side. Therefore, when the container 1 is basically used in the second open state, by placing the container 1 with the first central axis 36 side of the container 1 facing forward, the distance between the lid body opening 32 and the second lid body 51 and the user can be further shortened (the operation of putting an object into the container 1 through the lid body opening 32 can be performed more closely). This makes it easier to open and close the second lid 51, and also makes it easier to put an object into the container 1 through the opening 4 (lid opening 32) that opens when the container is in the second open state. Furthermore, while ensuring an appropriate opening area of ​​the opening 4 in the second open state, the height of the container 1 when the second lid 51 is pivoted upward by about 90 degrees from the closed position is kept lower than the height of the container 1 when the first lid 8 is pivoted upward by about 90 degrees from the open position, making it easier to install the container in places with height restrictions.

[0041] Additionally, in the second open state, the second lid body 51 is configured to be supported by abutting against the first lid body 31 in a position extending upward relative to the upper edge of the container body 2. Therefore, for example, compared to a configuration in which the second lid body 51 in the closed position is rotated and displaced approximately 180 degrees, the operation for displacing the second lid body 51 to the open position and the operation for displacing the second lid body 51 in the open position to the closed position can be performed relatively easily. Also, in the second open state, the upper surface of the first lid body 31 in the closed position can be used as a workbench, and, for example, a plurality of predetermined objects can be placed on the first lid body 31, and all or some of the objects can be stored one by one in order into the container 1 (for example, storing the objects one by one in an organized manner, or removing tags from the objects and storing the tags, etc.).

[0042] Furthermore, the first operating unit 43 of the first lid body 8 is provided at a position on the opposite side of the first lid body main body 31 from the side on which the first central axis 36 is provided, and the second operating unit 54 of the second lid body 51 is provided so as to be disposed at a position on the side on which the first central axis 36 is provided of the first lid body main body 31 when the second lid body 51 is in the closed position. Therefore, by placing the container 1 so that the side of the container 1 opposite the first central axis 36 is facing forward, the first lid body 8 can be opened and closed relatively easily by operating the first operating unit 43. Furthermore, by placing the container 1 so that the side on which the first central axis 36 is facing forward, the second lid body 51 can be opened and closed relatively easily by operating the second operating unit 54.

[0043] In addition, the first operating unit 43 is provided on one side of the first and second side edges (in this example, the second side edge side) of the first lid body 31, adjacent to a first side edge opposite the side edge on which the first central axis 36 is provided, near the boundary between the first side edge and a second side edge extending in a direction intersecting the first side edge. Therefore, even when the container 1 is placed with the first central axis 36 side facing either the left or right side (with the second side edge facing forward), the first lid body 8 can be opened and closed relatively easily by operating the first operating unit 43. Furthermore, compared to a case in which the first operating unit 43 is provided on each of the first and second side edges of the first lid body 31, the shape and weight of the first lid body 31 can be simplified and the weight can be reduced.

[0044] The present invention is not limited to the above-described embodiment, and may be implemented as follows: Of course, other applications and modifications not exemplified below are also possible.

[0045] (a) In the above embodiment, the first lid body 8 is rotatably connected to one long side of the lid mounting frame 6, but the first lid body 8 may be rotatably connected to a short side of the lid mounting frame 6. In addition, the shape and arrangement of the second lid body 51 (lid body opening 32) are not particularly limited and can be changed as appropriate. For example, in the above embodiment, the lid body opening 32 is configured so that its entire periphery is surrounded by the first lid body main body 31, but it may also be configured so that a portion of it opens to the side. Note that with regard to the configuration in the above embodiment in which the extension directions of the first central axis 36 and the extension directions of the second central axis 57 extend parallel to each other, this is intended to include not only a configuration in which they are completely parallel, but also a configuration in which they are approximately parallel with only a slight angle shift, which provides similar effects.

[0046] Furthermore, the posture of the second lid body 51 in the open position is not particularly limited, but it is desirable that the second lid body 51 be able to stand on its own in the open position, and further, when the container 1 is placed with the first central axis 36 side facing forward, it is desirable that the angle be as close to vertical as possible so that the second operating part 54 of the second lid body 51 in the freestanding posture is as close to the vertical as possible in the short width direction of the first lid body 8 so as to not deviate as far as possible from the first central axis 36. Additionally, in the above embodiment, when the container 1 is in the closed state, the top surface of the first lid body 8 including the second lid body 51 is configured to extend in a substantially horizontal direction (by placing the container 1 on a horizontal installation surface), but it may also be configured to be supported at a slightly inclined angle relative to the horizontal direction, or the first base 33 of the first lid body main body 31 and the second base 52 of the second lid body 51 may be configured to be slightly curved (in whole or in part). Furthermore, the configuration for connecting the first lid body main body 31 to the lid mounting frame 6 in a manner that allows it to be rotated and displaced, and the configuration for connecting the second lid body 51 to the first lid body main body 31 in a manner that allows it to be rotated and displaced, are not particularly limited and can be changed as appropriate.

[0047] (b) In the above embodiment, the opening 4 of the container body 2 is closed by the first lid body main body 31 and the second lid body 51. However, the opening 4 may be closed by three or more lid bodies. For example, the number of lid bodies rotatably connected to the lid mounting frame 6 may be increased (the lid bodies may or may not have the same configuration as the first lid body main body 31 and the second lid body 51), the number of lid bodies rotatably connected to the first lid body main body 31 (similar to the second lid body 51 in the above embodiment, configured to open in the opposite direction to the first lid body 8, but the arrangement can be changed as appropriate, such as adjacent to the second lid body 51 in the longitudinal width direction of the first lid body 8 or in the lateral width direction of the first lid body 8, or spaced apart from the second lid body 51), or the number of lid bodies rotatably connected to the second lid body 51 (a second lid body opening is provided in the second lid body 51, and a lid body that opens and closes the second lid body opening) may be increased. Furthermore, when an opening other than the lid opening 32 is provided in the first lid body main body 31, or when a second lid opening is provided in the second lid body 51, the lid that opens and closes such an opening is not limited to a configuration in which it rotates and displaces so that the central axis direction is horizontal, but may also be configured, for example, to slide and displace horizontally relative to the first lid body main body 31 or the second lid body 51.

[0048] (c) In the above embodiment, the lid mounting frame 6 may be omitted, and the first lid 8 may be directly connected to the container body 2. The bag stopper member 27 may also be omitted. A structure (retaining means) for holding the first lid 8 or the second lid 51 in the closed position may be provided. However, it is desirable that the retaining means be configured to be able to maintain (without applying external force) both a restricting state that restricts displacement of the first lid 8 or the second lid 51 in the closed position and an allowing state that allows displacement. In this case, by setting the retaining means to the restricting state when the first lid 8 or the second lid 51 is never in the open position and to the allowing state otherwise, a usage mode can be achieved in which the second lid 51 can be opened and closed relatively easily, as in the above embodiment.

[0049] (d) In the above embodiment, the container body 2, the lid mounting frame 6, the first lid body 31, and the second lid 51 are made of polypropylene, but they may be made of other resin materials such as polyethylene, PET, polyamide, etc. Furthermore, the shape and use of the container 1 are not particularly limited, and it may be embodied as, for example, a storage box for storing multiple identical objects together.
