  By the way, in the lid member of the lidded container disclosed in Patent Literature 1, the side portion of the lid member in the closed position is exposed to the outer peripheral side of the container body, and the worker is positioned with respect to the side portion of the lid member. There is a concern that the cover member may be caught unintentionally and the cover member may be damaged, or the cover member may be displaced toward the open position.

  The present invention has been made to solve the above-described problems and the like, and has as its object to prevent inadvertent lifting of a lid member in a closed position and to protect side edges of the lid member. An object of the present invention is to provide a container with a lid which can be designed.

  Hereinafter, each means suitable for solving the above-mentioned objects and the like will be described separately. In addition, a function and effect specific to the corresponding means will be added as necessary.

Means 1. A bottom wall component having a substantially rectangular plate shape, and a side wall component extending upward from each side of the bottom wall component, a substantially box-shaped container body that opens upward,
A lid member that is rotatably attached to an upper side of the side wall component and is displaceable between an open position that opens an opening of the container body and a closed position that closes an opening of the container body. In a container with a lid comprising:
The side wall component includes a pair of opposing first side wall components and a pair of opposing second side wall components,
The lid member is attached to each of the first side wall components,
A lower surface side of the lid member in the closed position is supported by an upper side portion of the second side wall component,
The upper side portion of each of the second side wall constituting portions is a protection that is in contact with or near at least a portion of the side portion of the lid member that is in the closed position, including a portion on the leading edge side of the lid member. Department is provided ,
The container body includes a side wall portion extending upward from each side portion of the bottom wall constituting portion, and a rectangular frame-shaped upper frame provided along an upper side portion of the side wall portion,
Each of the first side wall constituting portions and each of the second side wall constituting portions are constituted by the respective side wall portions and a portion of the upper frame located above the side wall portions,
The side wall portion is a lower wall portion whose lower side portion is rotatably connected to a side portion of the bottom wall forming portion, and an upper side portion is rotatably connected to the upper frame, A pair of opposing bent side walls having an upper wall whose lower side is rotatably connected to an upper side of the lower wall, and the upper side is rotatable with respect to the upper frame. A pair of opposing flip-up side walls to be connected,
Of the upper frame, the second frame component corresponding to the second side wall component is provided with a finger hook on which a worker can put a finger,
The container with a lid , wherein the protection part is provided so as to protrude upward from an upper side of the second frame constituent part at a position above the finger hook part .

  According to the means 1, an operator or another member is unintentionally caught on the side of the lid member, and the lid member is damaged or the lid member is displaced to the open position side. Such a situation can be suppressed. In particular, among the side edges of the lid member, the lid member is relatively easy to lift up when hooked, and is further protected corresponding to the edge on the leading edge side of the lid member, which is also a portion that is relatively easily deformed and damaged. Since the portion is provided, the above-described operation and effect can be more reliably and effectively achieved.

  Further, the provision of the protection portion can suppress a situation in which a gap is formed between the lid member in the closed position and the container body, and can suppress intrusion of dust and the like.

When the lid member 3 is set to the closed position, the finger-hanging convex portion 65 of the lid member 3 is inserted into the exposure concave portion 64 of the upper frame 7. That is, the finger hook convex portion 65 is configured to be exposed to the outer peripheral side of the upper frame 7 via the exposure recess 64, and in this embodiment, the finger hook convex portion inserted into the exposure recess 64 is provided. The front end of the short side 65 and the outer surface of the short side protection portion 31 are substantially flush. In particular, the finger-hanging convex portion 65 of the upper lid member 3 of the pair of lid members 3 at the closed position is separated upward from the lower edge of the concave portion 64 for exposure. For this reason, when displacing the upper lid member 3 among the lid members 3 in the closed position to the open position side, the fingertip can be hung on the finger hook 65 of the upper lid member 3 and lifted. The workability of displacing the upper lid member 3 toward the open position is improved.

  As shown in FIGS. 1, 3, and the like, a finger insertion recess 63 provided on the outer surface side of each short side frame forming portion 12 is provided with a pair of finger recesses 63 provided on the upper surface side of each short side frame forming portion 12. Are provided corresponding to the portions between the short-side positioning protrusions 57. That is, in the short side frame forming section 12, in the longitudinal direction of the short side frame forming section 12, it corresponds to the portion where both the handle cutout section 62 and the finger insertion concave section 63 are provided. On the upper surface side of the short side frame forming section 12, a short side protection section 31 (without the exposure recess 64) is provided.

  As described above in detail, according to the present embodiment, the short-side housing portion 27 is provided with the short-side protection portion 31 that is in contact with or close to the side portion of the lid member 3 that is in the closed position. The outer peripheral side of the upper frame 7 is covered by the short-side protection portion 31 at least at a portion including the end portion on the front edge side of the lid member 3 among the side portions of the lid member 3 in the closed position. It has become. For this reason, an operator or another member is inadvertently caught on the side of the lid member 3 in the closed position, and the lid member 3 is damaged or the lid member 3 is displaced to the open position side. Can be suppressed. In particular, among the side portions of the lid member 3, the lid member 3 is relatively easy to lift up when hooked, and furthermore, the end on the distal edge side of the lid member 3 which is a portion that is relatively easily deformed or damaged is short. Since the side-side protection part 31 is covered, the above-described operation and effect can be achieved more reliably and effectively.

  Further, the provision of the short side protection portion 31 can suppress a situation in which a gap is formed between the lid member 3 in the closed position and the container main body 2, and prevent intrusion of dust and the like. Can be suppressed. Further, the short side protection portion 31 can prevent the lid member 3 from being displaced in the lateral width direction (the rotation axis direction). In addition, since the pair of lid members 3 that are placed in the closed position so as to overlap each other are covered from the outer peripheral side of the lidded container 1 by the short-side protection portion 31, the design can be improved.

  Further, the container body 2 of the present embodiment is a foldable type, and the lid member 3 is rotatably attached to the long-side frame forming portion 11 of the upper frame 7. Further, in the short side frame forming portion 12 provided with the short side housing portion 27, a notch portion 62 for a handle is provided at a lower side portion of the short side frame forming portion 12 including a center portion in the width direction. A finger insertion recess 63 is provided on the outer surface side. In other words, the central portion in the horizontal width direction of the short side frame forming portion 12 is a portion where relatively high strength is required for the short upper and lower widths. In addition, as for the short side frame forming section 12, the improvement of the strength cannot be expected by attaching the lid member 3 (the shaft forming section 22 and the shaft section 23) like the long side frame forming section 11. .

  In this regard, in the present embodiment, the short-side protective portion 31 protruding upward from the short-side housing portion 27 with respect to at least the area in which the finger insertion concave portion 63 is provided in the width direction of the short-side frame forming portion 12. Is provided. For this reason, the strength of the portion above the finger insertion recess 63 in the short side frame forming portion 12 can be effectively improved. Therefore, when the lid-mounted container 1 is lifted by placing a finger on the finger insertion recess 63 or the notch 62 for the handle, deformation of the short-side frame forming section 12 can be prevented, and carrying and stacking can be performed. Storage can be performed stably.

  Further, according to the present embodiment, the opening of the container body 2 can be reliably closed regardless of which of the pair of lid members 3 in the open position is displaced to the closed position. Therefore, workability when closing the opening of the container body 2 can be improved as compared with a configuration in which the container body 2 cannot be closed unless both the lid members 3 are simultaneously displaced to the closed position. it can.

  Further, according to the present embodiment, only the upper lid member 3 of the pair of lid members 3 in the closed position can be displaced to the open position, and the lower lid member 3 can be kept in the closed position. . Therefore, when the opening of the container body 2 only needs to be partially opened, it is not necessary to displace both the lid members 3 to the open position, and the convenience can be improved.

  Further, in a state where the pair of lid members 3 are in the closed position, the top edge portions of the pair of lid members 3 are vertically overlapped, but each side of the pair of lid members 3 in the closed position. The portion is accommodated in each short side accommodation portion 27, and basically, the entire longitudinal direction of each side portion of the pair of lid members 3 is covered by the short side protection portion 31 from the outer peripheral side of the lidded container 1. It has become. For this reason, it is possible to avoid a situation in which the upper lid member 3 projects upward from the container body 2. Therefore, since the upper lid member 3 projects upward from the container main body 2, the risk of the lid member 3 being damaged by contact with other members or the like increases, and the lidded containers 1 can be stacked. Problems such as disappearance can be eliminated.

  In addition, by extending the lower lid member 3 of the pair of lid members 3 so as to be inclined downward, the upper lid member 3 can be extended in a substantially horizontal direction. Thereby, the lid member 3 in the closed position largely protrudes upward from the container main body 2 without extremely reducing the thickness of the vertically overlapping portion of the pair of lid members 3 in the closed position. Or the protruding length of the short side protection portion 31 (depth of the short side storage portion 27) increases, and the strength of the short side storage portion 27 (short side protection portion 31) decreases. While avoiding the situation, the tip end sides of the pair of lid members 3 can be vertically overlapped, and each side portion of the pair of lid members 3 can be accommodated in the short side accommodation portion 27. Therefore, the degree of freedom of the shape of the cover member 3 is improved, and the thickness of the portion on the front edge side of the cover member 3 is secured (the front rib 42, the horizontal rib 45, the vertical rib 46, and the side rib 41 are provided. And a shape that can secure the strength of the portion on the leading edge side), and the portion on the leading edge side of the lid member 3 is likely to be deformed or damaged due to the thin configuration on the leading edge side. Can be prevented.

  Furthermore, as compared with a configuration in which the upper lid member 3 is inclined upward toward the leading edge, a situation in which the upper lid member 3 is inadvertently displaced to the open position due to vibration or the like is suppressed. be able to. In addition, the side portion of the lid member 3 in the closed position and the short side protection portion 31 can be opposed to each other in a wide range as much as possible, so that other members are caught on the inner surface of the short side protection portion 31. In addition to the suppression, when another member comes into contact with the outer surface of the short side protection portion 31, the cover member 3 can suppress the inward deformation of the short side protection portion 31.

  Further, when the pair of lid members 3 are set to the closed position, the configuration in which the tip end sides of the pair of lid members 3 vertically overlap with each other prevents formation of a gap between the lid members 3, The members 3 can be engaged with each other, or the lower cover member 3 can support the front edge of the upper cover member 3. Further, the lower surface of the lower lid member 3 of the pair of lid members 3 in the closed position is supported by the short-side housing portion 27, so that the lid member 3 in the closed position further includes the container body. 2 can be prevented from being displaced (downward) so as to enter the inside of 2. In addition, for example, the short side housing portion 27 that supports the lower surface side of the lid member 3 in the closed position is not provided (for example, the lid member 3 in the closed position is supported only around the shaft portion 23). As compared with the configuration, it is possible to stabilize the lid member 3 in the closed position, to improve the durability of the configuration for pivotally supporting the lid member 3, and the like.

  In addition, the short side housing portion 27 is provided with an inclined portion 28 that supports the lower surface of the lower lid member 3 of the pair of lid members 3. Therefore, the lower lid member 3 can be more stably supported, and the upper lid member 3 supported by the lower lid member 3 can be more stably supported. Further, it is possible to suppress a situation in which the lower lid member 3 is pressed downward by the upper lid member 3 and bends. In particular, the inclined portion 28 of the present embodiment is configured such that the shorter side housing portion 27 is closer to the long side frame forming portion 11 (the bearing portion 26 side) than the range in which the pair of lid members 3 set to the closed position overlap each other. Therefore, when the lower lid member 3 is pressed downward by the upper lid member 3, the shaft component 22 and the bearing 26 can be protected. In addition, the provision of the inclined portion 28 in the short side housing portion 27 can increase the rigidity of the peripheral portion.

  In addition, since both sides of the lid member 3 in the closed position are accommodated in the short side housing portions 27, both sides of the lower surface of the lower lid member 3 are supported by the short side housing portions 27, respectively. be able to. Further, the upper cover member 3 is supported at both sides of the lower cover member 3 at both ends of the lower cover member 3 that are stably supported by the short-side housing portion 27. Becomes Therefore, the pair of lid members 3 at the closed position can be more stably supported, and the inclination, deformation, and the like of the lid member 3 at the closed position can be more reliably suppressed. In addition, since the deformation of the lid member 3 at the closed position is prevented, formation of a gap between the lid members 3 and between the lid member 3 and the container body 2 can be suppressed. In addition, in the present embodiment, when the tip edges of the lid member 3 extend linearly and the pair of lid members 3 are set to the closed position, the distal rib 42 comes into contact with the upper surface of the lower lid member 3. Therefore, the gap between the lid members 3 can be minimized.

  In addition, the short side housing portion 27 is provided with a flat portion 29 that substantially abuts on the distal end edge of the lower cover member 3 of the pair of cover members 3 set to the closed position. It extends in the horizontal direction at least in a range including a range where the pair of lid members 3 at the closed position overlap each other. Therefore, regardless of which of the pair of lid members 3 whose leading edge sides overlap each other when the pair is placed in the closed position (even if the lower lid member 3 is replaced), the pair of lid members 3 is placed in the closed position first. The lid member 3 located on the lower side can be accommodated in an oblique posture, and the opening of the container body 2 can be similarly closed (the inclined portion 28 for supporting one lid member 3 This can avoid such a situation that the other lid member 3 is prevented from being accommodated in an oblique posture).

  Further, the flat portion 29 is provided with a fall prevention rib 34, and when the cover member 3 is in the closed position, the flat corresponding portion 44 of the side rib 41 of the cover member 3 is moved to the upper frame 7 of the fall prevention rib 34. , So as to be in contact with or close to the surface on the outer peripheral side. For this reason, the fall prevention rib 34 and the flat corresponding portion 44 can prevent the side portion of the lid member 3 in the closed position from being displaced toward the inner peripheral side of the container body 2 and can be in the closed position. It is possible to prevent a situation in which the side portion of the lid member 3 is displaced so as to fall into the opening of the container body 2. Therefore, the downward displacement and deformation of the lid member 3 at the closed position can be prevented. In particular, since the flat portion 29 corresponds to a portion on the distal end side of the lid member 3 in the closed position, the positioning of the lid member 3 is more effectively performed on the distal end side of the lid member 3 that is relatively easily displaced. It can be performed.

  The fall prevention rib 34 is configured to be within the range of the height of the short side housing portion 27 (so as not to protrude above the extension of the adjacent inclined portion 28). There). For this reason, it is possible to prevent the drop prevention rib 34 from protruding above the upper surface of the lid member 3 (the upper edge of the short side protection portion 31 that is the upper edge of the short side housing portion 27), Even if the strength of the fall prevention rib 34 is not increased more than necessary, the damage of the fall prevention rib 34 can be suppressed, and when stacking the lidded containers 1, the fall prevention rib 34 has the upper lid. It is possible to prevent the container 1 from being in the way.

  It should be noted that the present invention is not limited to the content described in the above embodiment, and may be implemented as follows, for example. Of course, other application examples and modifications not illustrated below are naturally possible.

  (A) In the above embodiment, the lower lid member 3 of the pair of lid members 3 in the closed position is supported in a posture in which the lower lid member 3 extends obliquely. The inclined portion 28 is provided in a range where the paired lid members 3 do not overlap with each other. For example, instead of the inclined portion 28, a rib or a projection for supporting the lid member 3 may be provided.

  In addition, the inclined portion 28 is omitted, and the lower lid member 3 of the pair of lid members 3 set in the closed position is in contact with and supported by the short side housing portion 27 only at the front edge side of the lid member 3. May be configured. However, a portion of the lid member 3 that is closer to the shaft portion 23 than a portion that overlaps with the other lid member 3 when the lid member 3 is set to the closed position is also supported by the short-side housing portion 27 (contacts or With such a configuration that the cover member 3 abuts by slightly bending or the like, deformation of the lid member 3 and the like can be suppressed, and the durability of the shaft component portion 22 and the bearing portion 26 can be improved.

  (B) Further, for example, a portion of the short side housing portion 27 corresponding to the flat portion 29 of the above-described embodiment extends on an extension line of the pair of inclined portions 28, and a lower surface side of the tip end side of the lid member 3. Is provided, and is supported between each inclined portion 28 (base end supporting portion) and each distal end supporting portion by each inclined portion 28 and each distal end supporting portion. Providing a recess (central recess) that allows the other cover member 3 to be accommodated in an oblique position when the opening of the container body 2 is closed with the other cover member 3 different from the cover member 3 as the lower side. It may be. It should be noted that the distal end side support portion may not be constituted by a surface but may be constituted by a rib, a projection or the like.

  In the above embodiment, the lid member 3 is configured such that the thickness (the length of the protrusion of the various ribs from the lid main body 21) gradually decreases from the shaft portion 23 side toward the distal end edge side. The present invention is not limited to this. For example, the thickness may be made substantially constant. In this case, only the leading edge of the lid member 3 comes into contact with the flat portion 29 on the distal end side of the lid member 3.

  Further, the flat portion 29 is configured such that the flat corresponding portion 44, the tip rib 42, and the lateral rib 45 of the lower lid member 3 at the closed position are in contact with and supported by the flat portion 29. Of these, only a part may be configured to abut, or if the lid member 3 is supported by the inclined portion 28, the lower lid member 3 may abut when it is slightly bent. It may be configured or configured not to abut at all.

  In addition, the fall prevention rib 34 of the above embodiment is provided so as to correspond to the flat portion 29 and is configured so as not to protrude above an extension of the adjacent inclined portion 28. It is not limited to such a configuration. For example, it is also possible to provide them corresponding to the inclined portions 28. However, in order to avoid a situation in which the drop prevention rib 34 protrudes upward from the upper surface of the lid member 3 and the drop prevention rib 34 is easily damaged, the drop prevention rib 34 has a short side. It is desirable to configure so as to fall within the range of the height of the accommodation portion 27. Note that the drop prevention rib 34 can be omitted.

  (C) In the above embodiment, the width of the lid main body 21 in the centrifugal direction may not be constant. For example, as shown in FIGS. An arc-shaped notch 71 may be provided. In this case, it becomes easy to put a fingertip on the tip edge of the lid member 3 through the cutout portion 71 of the upper lid member 3 in the closed position, and when displacing the upper lid member 3 in the closed position to the open position side. Workability can be improved. Further, also with respect to the lid member 3 in FIG. 17, both side portions of the distal end edge are respectively accommodated in the short side accommodating portions 27 and are reliably supported by the short side accommodating portions 27 in the side ribs 41 and the distal end ribs 42 and the like. Therefore, when a downward force is applied to the lid member 3 in the closed position, it is possible to prevent a problem such as the lid member 3 being inclined.

  In addition, you may comprise the front-end edge of the cover member 3 in another uneven shape. For example, it may be formed in a wave shape, or provided with a semicircular shape in plan view or a trapezoidal shape in plan view at an intermediate position in the width direction of the lid member 3 at the distal end edge of the lid member 3. The central part may be configured to protrude in the centrifugal direction of the lid member 3 from the two side parts. However, the lid member 3 in the closed position extends from the short side housing section 27 of one short side frame forming section 12 to the short side housing section 27 of the other short side frame forming section 12, It is desirable that both sides of the lower surface of the member 3 be configured to be supported by the short side housing portion 27. Furthermore, the distance from the rotation axis of the lid member 3 to the leading edge is the largest at both ends of the lid member 3 that is to be accommodated in the short side accommodation portion 27 when the lid member 3 is in the closed position. It is desirable that the structure be large. In this case, in a state where the pair of lid members 3 are in the closed position, both sides of the lower surface of the lower lid member 3 are supported by the short side housing portions 27, respectively. Are supported on both sides of the lower lid member 3 that are stably supported by the short-side housing portion 27, so that a pair of upper and lower lid members 3 in the closed position is provided. Can be stably supported.

  The lid member 3 of the lidded container 1 shown in FIGS. 17 to 19 is configured such that the first engaging portions 51 are provided adjacent to both side portions of the cutout portion 71. In this case, for example, when a force is applied to the upper lid member 3 in the closed position from above, the first engagement portion 51 of the upper lid member 3 The relative displacement is performed in a direction in which the engagement with the one engaged portion 52 is strengthened. Therefore, when the lidded containers 1 are stacked, the engagement between the lid members 3 can be made stronger, and the deformation and the like of the lid members 3 can be more reliably prevented.

  (D) In the above embodiment, it is also possible to omit the finger hook 65 and the exposure recess 64. In this case, the short side protection portion 31 can cover the entire area of the side portion of the cover member 3, preventing the cover member 3 in the closed position from being inadvertently lifted, and protecting the side portion of the cover member 3. The operation and effect of achieving the above are more reliably achieved. In this case, the notch 71 shown in FIG. 17C (see FIGS. 17 to 19) may be provided, or a knob on the upper surface side of the lid member 3 that can be picked up with a fingertip to lift the lid member 3. By providing the cover member, it is possible to solve a problem that it is difficult to displace the upper lid member 3 at the closed position toward the open position.

  Further, in the above embodiment, the short side protection portion 31 is basically provided in the entire area of the short side frame forming portion 12, but at least the distal end of the lid member 3 among the side portions of the lid member 3. What is necessary is just to be comprised so that the site | part containing the edge part on the edge side may be covered. However, by providing the short side protection portion 31 as wide as possible, it is possible to prevent inadvertent contact with the side portion of the lid member 3 and to prevent the pair of lid members 3 (particularly, A situation in which a gap is formed between the upper lid member 3) and the upper frame 7 can be suppressed, and effects such as prevention of intrusion of dust and the like can be obtained.

  For example, as in the above-described embodiment, when a pair of the lid members 3 in the closed position is configured such that the leading edge sides in the centrifugal direction from the rotation axis of each of the lid members 3 overlap vertically. Of the side portions of the lid member 3 in the closed position, at least a pair of the lid members 3 opposes or abuts or approaches a portion including a range where the lid members 3 overlap each other (including an end portion on the leading edge side of the lid member 3). Thus, the short side protection portion 31 may be provided.

  In this case, it is possible to suppress a situation in which the upper lid member 3 that is relatively easy to open than the lower lid member 3 of the pair of lid members 3 in the closed position is displaced toward the open position. Can be. In particular, among the side portions of the lid member 3, the lid member 3 located on the upper side when it is hooked is relatively easily lifted, and further, the lid member 3 located on the upper side which is also a part that is relatively easily deformed or damaged. Since the short side protection portion 31 is provided corresponding to the portion on the front edge side of the above, another member is hardly caught by the lid member 3 and the lifting of the lid member 3 and the damage on the front edge side are suppressed. Such an effect is more reliably and effectively achieved.

  (E) In the above embodiment, the container main body 2 is configured to be foldable. For example, the container main body 2 includes a bottom wall configuration portion, and a side wall portion extending upward from each side of the bottom wall configuration portion. It is also possible to employ a non-foldable container body 2 in which these are integrally formed. When this configuration is employed, the side wall portion (the long side wall portion and the short side side wall portion) forms a side wall forming portion (first side wall forming portion and second side wall forming portion). Furthermore, in the above-described embodiment, the lidded containers 1 are configured to be stacked one on another. However, the present invention can be applied to a lidded container 1 that cannot be stacked.

  Further, in the above embodiment, the lid member 3 is attached to the long side frame forming section 11, but it may be configured to be attached to the short side frame forming section 12. Further, in the above-described embodiment, the lid member 3 is attached to the upper side of the long side frame forming section 11, but is larger than the upper side of the long side frame forming section 11 (first side wall forming section). The cover member 3 may be configured to be attached corresponding to the lower position. In addition, in the above-described embodiment, the pair of lid members 3 have the same shape. However, different shapes may be combined. For example, a lid including the pair of lid members 3 having different widths in the centrifugal direction. It is also possible to apply to a container with a container.

  Further, a main body-side pivoted portion rotatably connected to the upper frame 7 (the main body-side pivot provided in the upper frame 7) and a pivot relative to the lid member 3 (the lid-side pivotal support provided in the upper frame 7). The lid member 3 is connected to the container main body 2 via a hinge part having a lid side shaft attachment portion that is connected to the container main body 2 so that the lid member 3 can rotate about two center axes with respect to the container main body 2 respectively. It is also possible to apply to a configured container with a lid.

  (F) In the above embodiment, the lower lid member 3 of the pair of lid members 3 in the closed position is inclined downward toward the leading edge, but the pair of lids in the closed position is used. If both sides of the member 3 are configured to be housed in the short side housing portions 27 respectively (they do not protrude above the upper frame 7 (the short side protection portion 31 and the like)), the lower lid member 3 may be configured to extend in a substantially horizontal direction. However, since the lower lid member 3 is inclined downward toward the front edge, the upward projection amount of the upper lid member 3 can be suppressed, and the side of the upper lid member 3 is shortened. It is possible to avoid a situation in which the protruding length of the short-side protection portion 31 is lengthened so that the short-side protection portion 31 is accommodated in the side-side accommodation portion 27 (further, the distal end side of the short-side protection portion 31 is easily deformed or damaged). . Further, it is desirable that the upper lid member 3 extends in a substantially horizontal direction. For example, the volume of the lidded container 1 in the closed state is smaller than a configuration in which the upper lid member 3 is inclined downward toward the front edge. Can be avoided. Furthermore, compared to a configuration in which the upper lid member 3 is inclined upward toward the distal end edge, while suppressing an increase in the protruding length of the short side protection portion 31 and flapping of the upper lid member 3 in the closed position, The side portion of the lid member 3 at the closed position and the short side protection portion 31 are opposed to each other as widely as possible, and a portion of the short side protection portion 31 protruding above the lid member 3 at the closed position. Can be reduced, and the short side protection portion 31 can be protected by the lid member 3 at the closed position.

  Further, in the above-described embodiment, the portions on the distal end side of the pair of lid members 3 in the closed position are configured to overlap vertically, but the pair of lid members 3 do not overlap vertically (for example, the closed position and the closed position). It is also possible to apply to the container 1 with a lid (a pair of the provided lid members extend substantially horizontally at the same height position).

  (G) The container body 2 and the lid member 3 are made of polypropylene, but may be made of other resin materials such as polyethylene, PET, polyamide and the like.
