[0020] The following describes the container 10 corresponding to the "lidded container" in the claims with reference to Figures 1 to 8. As shown in Figures 1 and 2, the container 10 comprises a container body 11 with an open top (corresponding to the "container body" in the claims) and a lid 30 (corresponding to the "lid" and "lidded container" in the claims) which can be attached to the container body 11 and has a storage section 35 that can be closed by a door member 50 (corresponding to the "lid member" in the claims).

[0021] As shown in Figure 2, the container body 11 is box-shaped with side walls 13 rising from the outer edge of a rectangular bottom wall 12. An upper flange 15 protrudes outward from the upper end, and an intermediate flange 16 protrudes outward slightly below the upper flange 15. The amount of protrusion of the intermediate flange 16 is greater than the amount of protrusion of the upper flange 15. The intermediate flange 16 and the upper flange 15 are connected by a plurality of connecting ribs 15L. The outer end faces of these connecting ribs 15L are flush with the outer end face of the upper flange 15. That is, the lower ends of the connecting ribs 15L are located inward from the outer edge of the intermediate flange 16.

[0022] Furthermore, the container body 11 is provided with corner vertical ribs 17A hanging down from the four corners of the container body 11, and corner lateral vertical ribs 17B hanging down from both sides of the corners, on the lower surface of the intermediate flange 16. The lower end of the corner lateral vertical rib 17B is located above the lower end of the container body 11, and the lower end of the corner vertical rib 17A is located above the lower end of the corner lateral vertical rib 17B. The lower end of the corner vertical rib 17A, the lower end of the side of the corner lateral vertical rib 17B, and the lower end of the side wall 13 are connected by a corner connecting wall 18. The corner connecting wall 18 slopes downward little by little as it moves outward from the side wall 13. From the outer edge of this corner connecting wall 18, the corner outer wall 19 hangs down to the height of the lower end of the corner lateral vertical rib 17B.

[0023] Furthermore, the side walls 13 that rise from the long side of the bottom wall 12 have lower end flanges 20 that extend laterally, connecting the lower ends of the corner lateral vertical ribs 17B at both ends. When the container bodies 11 are stacked, the lower end flanges 20 and the lower ends of the corner lateral vertical ribs 17B of the upper container body 11 come into contact with the upper end flange 15 of the lower container body 11, and the lower end of the upper container body 11 (the part below the lower end flange 20) fits into the upper opening 11K of the lower container body 11, thereby restricting lateral displacement of the upper and lower container bodies 11.

[0024] As shown in Figures 2 and 3, the lid 30 has a structure in which an outer fitting wall 32 hangs down from the outer edge of the lid body portion 31 that closes the upper opening 11K of the container body 11, and is fitted to the outside of the upper end flange 15 and connecting rib 15L of the container body 11. The outer fitting wall 32 extends in a way that it widens as it goes downward, and its lower end abuts against or is close to the intermediate flange 16 of the container body 11.

[0025] A ridge portion 33 is formed along the outer edge of the lid body portion 31. The ridge portion 33 has a rectangular groove-like cross-section with an open bottom and overlaps the upper end flange 15 of the container body 11 from above. At the lower end of the ridge portion 33, there are inner edge protrusions 33N and outer edge protrusions 33M that protrude slightly to the sides. In addition, multiple reinforcing ribs 33L are formed inside the ridge portion 33 so as to cross the ridge portion 33 in the width direction. The lower end of these reinforcing ribs 33L is located slightly below the lower end of the ridge portion 33 and connects the upper ends of the outer fitting wall 32 and the inner fitting wall 38, which will be described later. When the lid body 30 is placed over the container body 11, the reinforcing ribs 33L come into contact with the upper end flange 15 of the container body 11.

[0026] As shown in Figure 4, when the container bodies 11 are stacked on top of the lid 30, the lower end flange 20 and the lower end of the corner lateral vertical rib 17B of the upper container body 11 come into contact with the upper surface (upper end flange 15) of the rim portion 33 of the lid 30, and the lower end of the container body 11 (the portion below the lower end flange 20) fits inside the rim portion 33 of the lid 30.

[0027] As shown in Figures 2 and 3, the lid body 31 has the aforementioned storage section 35 formed inside the embankment 33. The storage section 35 has a bottom wall 35A and a side wall 35B rising from its outer edge (corresponding to the "opening-forming wall" in the claims), and its planar shape is slightly smaller than the inner portion of the embankment 33. The opening of this storage section 35 corresponds to the "opening" in the claims. In addition, a flat section 36 is provided between one short side of the embankment 33 (hereinafter referred to as the "first short side section 33A") and the storage section 35 of the lid body 31, by extending the inner edge protrusion 33N of the embankment 33 inward. The upper end of the side wall 35B of the storage section 35 is located one plate thickness below the upper surface of this flat section 36. It is possible to create or print logos and other designs on this flat section 36.

[0028] An operating groove 40 is provided between the other short side of the embankment portion 33 (hereinafter referred to as the "second short side portion 33B") of the lid body portion 31 and the housing portion 35, extending in the short direction of the lid body 30. The operating groove 40 is composed of a groove side wall 40B hanging down from the end of the inner edge protrusion portion 33N of the second short side portion 33B, a side wall 35B of the housing portion 35, and a groove bottom wall 40A connecting the lower end of the groove side wall 40B and the middle part of the side wall 35B of the housing portion 35, and its depth is about half the depth of the housing portion 35. The operating groove 40 is also closed by a groove closing wall 40C hanging down from the inner edge protrusion portion 33N of the second short side portion 33B side end of the long side portion of the embankment portion 33.

[0029] The lid body portion 31 is provided with an inner edge rib 37 that hangs down from the portion of the inner edge protrusion portion 33N of the embankment portion 33 other than the portion where the groove side wall 40B and groove closing wall 40C are provided. The inner edge rib 37 extends flush with the groove closing wall 40C. The inner edge rib 37, the groove closing wall 40C and the groove side wall 40B form an inner fitting wall 38, which fits inside the side wall 13 of the container body 11.

[0030] Lid fitting grooves 41 are provided on both long sides and the short side on the side of the first short side 33A of the lid body 31 around the housing portion 35. The long side of the lid fitting groove 41 is composed of the side wall 35B of the housing portion 35, the inner edge rib 37, and a connecting wall (not shown) that connects the two. The short side of the lid fitting groove 41 on the side of the first short side 33A is composed of the side wall 35B of the housing portion 35 and a groove-forming wall 41H that extends laterally from a position near the upper end of the side wall 35B and then rises upright.

[0031] As shown in Figure 3, the lid body portion 31 has an extension wall 39 extending from the upper edge of the groove-forming wall 41H toward the flat portion 36, and a pair of hanging walls 39S, 36S hanging down from the opposing ends of the extension wall 39 and the flat portion 36. The space between the pair of hanging walls 39S, 36S is a slit-shaped door fixing portion 42.

[0032] As shown in Figures 1 and 2, the lid 30 is equipped with a door member 50 that can open and close the storage section 35. The door member 50 shown in Figures 5 and 6 comprises a rectangular door body 51 in plan view that covers the lid body 31 (see Figure 3) from the door fixing portion 42 to the end of the second short side portion 33B of the storage section 35, and a fixing piece 52 for fixing the door member 50 to the lid 30. A thin hinge portion 50H is formed between the fixing piece 52 and the door body 51.

[0033] As shown in Figures 3 and 6, the fixing piece 52 hangs downward from almost the entire side edge on the first short side portion 33A of the door body portion 51. The fixing piece 52 is also provided with three projections 52A that protrude downward from the lower edge in the extending direction. The lower end of each projection 52A is a locking claw 52B. When the fixing piece 52 is inserted into the door fixing portion 42, the projections 52A protrude from the lower ends of the pair of hanging walls 39S and 36S, and the locking claw 52B engages, thereby fixing the door member 50 to the lid 30 so that it can rotate.

[0034] The door body 51 is provided with a door fitting portion 51K (corresponding to the "outer edge projection wall" in the claims) that is received in the lid fitting groove 41 and fitted to the outside of the side wall 35B of the housing portion 35. The door fitting portion 51K hangs down from the portion of the outer edge of the door body 51 from the end on the second short side portion 33B side to the end on the first short side portion 33A side, and from the portion connecting these end-side positions. The inner edge rib 37, the groove closing wall 40C, the groove side wall 40B, and the hanging wall 36S constitute a "surrounding wall" that encloses the door member 50.

[0035] As shown in Figures 1 and 6, the door member 50 is provided with an operating projection 55 that extends from the center of the side edge on the second short side 33B side of the door body 51 toward the second short side 33B side of the door body 51. The operating projection 55 has a rectangular shape in plan view, and its tip 55S is close to the groove side wall 40B. A projection hanging wall 56 (corresponding to the "outer edge projection wall" in the claims) hangs down from the outer edge of the operating projection 55.

[0036] The amount of protrusion of the projection hanging wall 56 at the tip 55S of the operating projection 55 is smaller than the amount of protrusion of the door fitting portion 51K. Furthermore, the amount of protrusion of the projection hanging wall 56 at the side portion 55T of the operating projection 55 is the same as the amount of protrusion of the projection hanging wall 56 at the tip 55S of the operating projection 55 from the second short side 33B side to the part of the way toward the first short side 33A side (hereinafter referred to as the "finger grip portion 55Y" as appropriate), and from that part onward, it increases as it approaches the first short side 33A side. At the end of the projection hanging wall 56 on the second short side 33B side, its lower end is located below the lower end of the door fitting portion 51K and is located one to two plate thicknesses above the bottom surface of the operating groove 40 (see Figure 4).

[0037] As shown in Figures 4 and 7, a hanging connecting wall 57 (corresponding to the "connecting wall" in the claims) hangs down from the base end of the operating projection 55, connecting the ends of the projection hanging wall 56 on the first short side 33A and the ends of the door fitting portion 51K. The lower end of the hanging connecting wall 57 and the lower end of the projection hanging wall 56 are continuous.

[0038] Furthermore, an engaging recess 57K is formed in the lateral center of the lower end of the hanging connecting wall 57, recessed toward the second short side portion 33B. On the other hand, an engaging projection 35T is formed on the outer surface of the side wall 35B of the housing portion 35 of the door body portion 51 at a position corresponding to the engaging recess 57K of the door member 50. The engaging projection 35T has an upper surface which is a guide inclined surface 35T1 that slopes downward toward the second short side portion 33B, while its lower surface is a flat locking surface 35T2. Near the base end of the operating projection 55, a recess 55U is formed that is recessed to the upper wall of the engaging recess 57K, and the wall portion constituting this recess 55U is in contact with the wall portion constituting the engaging recess 57K, reinforcing the hanging wall 56 of the projection (see Figures 4 and 8).

[0039] As shown in Figures 1 and 8, when the door member 50 closes the housing section 35, the door fitting portion 51K is received in the lid fitting groove 41 and fitted to the outside of the side wall 35B of the housing section 35, and the engaging projection 35T of the side wall 35B of the housing section 35 engages with the engaging recess 57K of the operating projection 55. This stabilizes the state in which the door member 50 closes the housing section 35. At this time, the operating projection 55 of the door member 50 is received in the operating groove 40, and a first space K1 exists on both sides of the operating projection 55 (both sides in the short direction of the lid 30), and a second space K2 exists below the operating projection 55, communicating with the first space K1. The upper surface of the door member 50 and the upper surface of the flat portion 36 are located on the same plane.

[0040] To open the door member 50, insert your finger from the side of the operating projection 55 in the operating groove 40 (first space K1) to the back side of the operating projection 55 (second space K2), place your finger on the finger rest 55Y, and push upward. This will cause the operating projection 55 to flex, releasing the engagement between the engaging recess 57K and the engaging projection 35T. By rotating the operating projection 55 upward in this manner, the door member 50 will rotate, and the storage section 35 will open. The presence of the recess 55U makes the operating projection 55 more flexible.

[0041] When closing the door member 50, the door member 50 is rotated downward so that the door fitting portion 51K is received in the lid fitting groove 41. Then, the lower end wall of the engaging recess 57K of the operating projection 55 comes into contact with the guide inclined surface 35T1 of the engaging projection 35T, and the operating projection 55 is guided to bend. As the lower end wall of the engaging recess 57K passes the engaging projection 35T, the operating projection 55 elastically returns, and the lower end wall of the engaging recess 57K faces the locking surface 35T2 of the engaging projection 35T, and the engaging recess 57K and the engaging projection 35T engage.

[0042] The configuration of the container 10 in this embodiment is as described above. Next, the effects of the container 10 will be explained. In the container 10 of this embodiment, a storage section 35 is provided in the lid 30, so luggage can be stored separately from the inside of the container body 11. Moreover, since the storage section 35 can be closed by the door member 50, luggage inside the storage section 35 is prevented from falling out.

[0043] In conventional containers, a space is provided between the tip of the operating projection on the door member and the side wall of the receiving recess that receives the operating projection. The operating projection is operated by inserting a finger into this space. However, this configuration has the problem that when attempting to widen the storage section toward the operating projection, the space between the operating projection and the side wall of the receiving recess narrows, making it difficult to operate the operating projection.

[0044] In contrast, in this embodiment, the container 10 has an operating projection 55 that is operated not from between the projection and the groove side wall 40B, but from a first space K1 provided to the side of the operating projection 55. This makes it possible to expand the storage section 35 towards the second short side 33B while maintaining the operability of the operating projection 55. Furthermore, there is a second space K2 below the operating projection 55 that communicates with the first space K1, and it is possible to insert a finger behind the operating projection 55, making the operating projection 55 easier to operate.

[0045] Furthermore, when the door member 50 is closing the storage section 35, the engaging recess 57K of the door member 50 and the engaging projection 35T of the side wall 35B of the storage section 35 engage, preventing the door member 50 from opening due to impact or the like. Moreover, since the engaging recess 57K is located on the operating projection 55, the engagement can be released smoothly by operating the operating projection 55, improving operability. In addition, since the portion of the projection hanging wall 56 at the base end of the operating projection 55 extends to a position where it connects with the lower end of the hanging connecting wall 57, the hanging connecting wall 57 is reinforced, and damage to the engaging recess 57K is prevented.

[0046] Furthermore, by bringing the groove side wall 40B of the operating groove 40 into contact with or close to the side wall 13 of the container body 11 from the inside, and bringing the tip 55S of the operating projection 55 close to the groove side wall 40B, the storage section 35 can be made larger towards the second short side 33B.

[0047] Incidentally, if the operating projection 55 is left open without a surrounding wall, an operating space can be easily secured, and the storage section 35 (opening of the storage section 35) can be widened while ensuring operability. However, in the container 10 of this embodiment, the containers 10 can be stacked on top of each other, and the lid 30 is provided with a ridge portion 33 into which the upper container 10 fits. The storage section 35 is located inside the ridge portion 33. In this case, it is difficult to leave the outside of the operating projection 55 open, and the benefits of providing a space (first space K1) to the side of the operating projection 55 can be more fully enjoyed.

[0048] [Other embodiments] (1) The finger rest portion 55Y may protrude laterally rather than downward.

[0049] (2) The hanging wall 56 of the projection may extend to a position where it abuts against or is close to the bottom surface of the operating groove 40. In this case, damage to the operating projection 55 when it is subjected to a downward load is prevented. Note that the extension to a position where it abuts against or is close to the bottom surface of the operating groove 40 may be limited to the portion of the hanging wall 56 at the base end of the operating projection 55, or it may be the entire wall.

[0050] (3) There may be no space between the lower end of the operating projection 55 and the bottom surface of the operating groove 40, or the space may not be in communication with the first space K1.

[0051] (4) In the above embodiment, a space (first space K1) for operating the operating projection 55 was provided on both sides of the operating projection 55, but it may be provided on only one side. In this case, the operating projection 55 on the other side may be in close proximity to or in contact with the side wall of the operating groove 40.

[0052] (5) The lid 30 may be configured to have an opening that leads to the internal space of the container body 11, rather than to the storage section 35.

[0053] (6) The door member 50 may be configured to slide rather than rotate. Alternatively, the opening (the opening of the storage section 35) may be closed by a lid member that is removed from the lid body 30.

[0054] (7) In the above embodiment, the door member 50 was configured to close the storage portion 35 of the lid 30 of the container 10, but it may also be configured to close an opening provided on one side of the container itself (which may be the top or side).

[0055] While this specification and drawings disclose specific examples of the technology included in the claims, the technology described in the claims is not limited to these specific examples, but also includes various modifications and changes to these examples, as well as parts of the examples taken individually.
