[0008] [First embodiment] 1 to 14 show a container 10 according to a first embodiment. As shown in Fig. 1, the container 10 of this embodiment has a container body 11 that is open at the top, an inner lid 50 as a "fitting member," and a lid member 70. The inner lid 50 fits into the opening of the container body 11, and the lid member 70 fits into the container body 11 from the outside.

[0009] As shown in FIG. 2 , the container body 11 has a box shape with side walls 13, 14 rising from the four sides of a substantially square bottom wall 12, and an upper flange 15 extending outward from the upper end. A first intermediate flange 16 is disposed on the outer surface of the first side wall 13, which faces the first side wall 13 in the first horizontal direction H1, slightly below the upper flange 15 and extending horizontally across the entire area excluding both sides. A second intermediate flange 17 is disposed on the outer surface of the second side wall 14, which faces the second side wall 13 in the second horizontal direction H2, and extends horizontally to both sides of the first side wall 13. The second intermediate flange 17 is located between the upper flange 15 and the first intermediate flange 16 in the vertical direction. The amount of protrusion of the first and second intermediate flanges 16, 17 is greater than the amount of protrusion of the upper flange 15.

[0010] The lower edges of the side walls 13, 14 are provided with bottom flanges 18 that protrude outward from the container body 11 excluding the corner portions. The bottom flanges 18 are disposed at approximately the same height as the bottom wall 12. A notch 18K is formed in each bottom flange 18, and the notch 18K of the bottom flange 18 of the second side wall 14 is formed over a wider area than the notch 18K of the bottom flange 18 of the first side wall 13. The protrusion amount of the portion of the bottom flange 18 excluding the notch 18K is approximately the same as the protrusion amount of the first and second intermediate flanges 16, 17.

[0011] A plurality of vertical ribs 19, 20 are formed on the outer surfaces of the side walls 13, 14, connecting the upper end flange 15 and the lower end flange 18. More specifically, corner side vertical ribs 19 that sandwich the corners of the container body 11 are arranged on both sides of each side wall 13, 14, and intermediate vertical ribs 20 are arranged on the first side wall 13, inside the corner side vertical ribs 19 in the second horizontal direction H2. Note that, on the first side wall 13, a rib 16L protrudes downward from the outer edge of the first intermediate flange 16 between the intermediate vertical ribs 20, forming a handle portion 10K.

[0012] Corner connecting walls 22 are provided between the corner side vertical ribs 19 in the vertical center, and corner vertical ribs 21 are provided at the corners of the container body 11 to connect the corner connecting walls 22 with the upper end flanges 15. A hanging wall 23 hanging from the outer edge of the corner connecting wall 22 connects to the outer edge of the corner side vertical rib 19.

[0013] The end face of each vertical rib 19, 20, 21 below the first and second intermediate flanges 16, 17 is flush with the end faces of the first and second intermediate flanges 16, 17 and the lower-end flange 18, and the end face of the portion above the first and second intermediate flanges 16, 17 is flush with the end face of the upper-end flange 15. As a result, the outer shape of the portion of the container body 11 above the first and second intermediate flanges 16, 17 is smaller than the outer shape of the portion below the first and second intermediate flanges 16, 17, and step surfaces 16A, 17A are formed on the upper surfaces of the first and second intermediate flanges 16, 17.

[0014] 3, a lower surface protrusion 11A is formed on the lower surface (lower surface of bottom wall 12) of container body 11. Lower surface protrusion 11A has frame-shaped ribs 11B extending substantially along the extension lines of side walls 13 and 14, and lattice ribs 11C extending vertically and horizontally within frame-shaped ribs 11B. When container bodies 11 are stacked on top of each other, when the lower end flange 18 of the upper container body 11 abuts the upper end flange 15 of the lower container body 11, the lower surface protrusion 11A of the upper container body 11 fits into the opening of the lower container body 11, preventing the upper and lower container bodies 11 from shifting laterally.

[0015] 2, the container body 11 is formed with positioning recesses 15A recessed in the center of the upper flange 15 on each upper side, and positioning protrusions 18A protruding downward from the center of the lower flange 18 on each lower side. When the container bodies 11 are stacked on top of each other, the positioning protrusions 18A of the upper container body 11 fit into the positioning recesses 15A of the lower container body 11, thereby also preventing the upper and lower container bodies 11 from shifting sideways. The lower surfaces of the positioning protrusions 18A are substantially flush with the lower end surfaces of the lower protrusions 11A (see FIG. 3).

[0016] 2, in the container body 11 of this embodiment, a notch 25 is formed in the first side wall 13 by cutting out the upper end portion. More specifically, the notch 25 is formed in the first side wall 13 between the corner side vertical rib 19 and the intermediate vertical rib 20, and is adjacent to the second intermediate flange 17 from the inside in the second horizontal direction H2. The notch 25 cuts out a range of the first side wall 13 from the upper end flange 15 to the height of the second intermediate flange 17.

[0017] Furthermore, a step portion 26 is formed on the side walls 13, 14 of the container body 11 near the upper end, bending slightly outward to make the opening at the upper end larger than the opening at the lower end. The step portion 26 is disposed at the same height as the second intermediate flange 17 and extends around the entire circumference of the container body 11. As shown in FIG. 4 , a portion of the upper surface of the step portion 26 forms the bottom surface of the notch 25, and three reinforcing vertical ribs 27 connect the lower portion of the step portion 26 below the notch 25 to the first intermediate flange 16. The upper surface of the step portion 26 corresponds to the "placement portion" in the claims, and the portion of the step portion 26 that protrudes outward from the lower edge of the notch 25 corresponds to the "reinforcing rib" in the claims.

[0018] FIG. 5 shows the inner lid 50. The inner lid 50 includes a main plate portion 51 that is substantially square in plan view and corresponds to the upper opening of the container body 11. As shown in FIGS. 5 and 6, the main plate portion 51 includes a ceiling wall 51A, a hanging wall 51B that hangs down from the outer edge of the ceiling wall 51A, and a lattice rib 51C that protrudes from the underside of the ceiling wall 51A. The outer edge of the ceiling wall 51A of the main plate portion 51 is stepped higher than the inner portion. Corner bulges 51L that bulge upward with a groove-shaped cross section are formed at the four corners of the ceiling wall 51A of the main plate portion 51. The planar shape of the corner bulges 51L is L-shaped, extending along two sides that sandwich the corner of the ceiling wall 51A, and is located slightly inward from the outer edge of the ceiling wall 51A.

[0019] Inner lid 50 is provided with engaging protrusions 52 that protrude laterally from two positions on a pair of opposing sides of main plate portion 51. Engaging protrusions 52 are respectively disposed at positions corresponding to notches 25 of container body 11 and are elongated in second horizontal direction H2. Engaging protrusion 52 has a ceiling wall 52A that extends flush with ceiling wall 51A of main plate portion 51 and a hanging wall 52B that hangs down from the outer edge of ceiling wall 52A, and hanging wall 51B of main plate portion 51 and hanging wall 52B of engaging protrusion 52 are connected by a connecting rib 52C that extends in the short direction of engaging protrusion 52.

[0020] 7 and 8, the inner lid 50 can be fitted inside the top opening of the container body 11. In this state, the outer edge of the inner lid 50 (particularly the main plate portion 51) abuts against the step portion 26 of the container body 11, the engaging protrusion 52 is received in the notch portion 25 of the container body 11, and the engaging protrusion 52 or the boundary between the engaging protrusion 52 and the main plate portion 51 is supported by the bottom surface (step portion 26) of the notch portion 25, thereby positioning the inner lid 50 within the top opening of the container body 11. The inner lid 50 is supported all around by the step portion 26, including the bottom surface of the notch portion 25, so that the inner lid 50 is stably supported.

[0021] At this time, the engaging protrusion 52 of the inner lid 50 protrudes from the notch 25 of the container body 11 and is surrounded on three sides by the corner side vertical rib 19, the intermediate vertical rib 20, and the first intermediate flange 16, with the engaging protrusion 52 facing the first intermediate flange 16 with a gap between them. The outer end of the engaging protrusion 52 is positioned approximately flush with or slightly inward from the outer end surface of the corner side vertical rib 19 above the second intermediate flange 17 and the outer end surface of the intermediate vertical rib 20 above the first intermediate flange 16, but may protrude outward beyond the upper ends of the corner side vertical rib 19 and the intermediate vertical rib 20 depending on the rattle of the inner lid 50. Meanwhile, the engaging protrusion 52 does not protrude beyond the portion of the corner side vertical rib 19 below the second intermediate flange 17, the portion of the intermediate vertical rib 20 below the first intermediate flange 16, or the first intermediate flange 16, throughout the entire rattle range of the inner lid 50.

[0022] Fig. 9 shows a cover member 70. The cover member 70 has a substantially square main plate 71 and a fitting wall 75 that hangs down from the outer edge of the main plate 71. On the main plate 71 of the cover member 70, a bank portion 72 that extends along the outer edge and bulges upward to form a groove-shaped cross section is formed slightly inward from the outer edge. The bank portion 72 is discontinued at the center of each side of the cover member 70, thereby forming a positioning recess 73 at the center of each side of the cover member 70. As shown in Fig. 10, opposing groove side surfaces of the bank portion 72 are connected by a plurality of reinforcing ribs 72A.

[0023] 8 and 10 , an annular ridge 74 facing the fitting wall 75 is formed on the underside of the cover member 70, inside the bank portion 72. The lower end of the annular ridge 74 is located higher than the lower end of the fitting wall 75. In addition, three positioning ribs 76 are provided in the center of each side of the cover member 70, connecting the fitting wall 75 and the annular ridge 74. When the cover members 70 are stacked on top of each other, the bank portion 72 of the lower cover member 70 fits between the fitting wall 75 and the annular ridge 74 of the upper cover member 70, and the positioning rib 76 of the upper cover member 70 fits into the positioning recess 73 of the lower cover member 70, preventing the cover members 70 from shifting relative to each other.

[0024] As shown in Figures 8 and 11, when this lid member 70 is placed over the container body 11 with the inner lid 50 attached, the main plate 71 of the lid member 70 and the reinforcing rib 72A on the back of the bank portion 72 abut against the upper end flange 15 of the container body 11, and the fitting wall 75 of the lid member 70 fits from the outside into the upper end portions (parts above the first and second intermediate flanges 16, 17) of the side walls 13, 14 of the container body 11, and the positioning rib 76 of the lid member 70 (see Figure 10) fits into the positioning recess 15A of the container body 11 (see Figure 7).

[0025] 12, when containers 10 are stacked with lid members 70 attached, the underside protrusion 11A of the container body 11 of the upper container 10 fits into the bank portion 72 of the lid member 70 of the lower container 10, and the positioning protrusion 18A of the container body 11 of the upper container 10 fits into the positioning recess 73 of the lid member 70 of the lower container 10, thereby preventing misalignment between the containers 10. It is also possible to stack a mixture of containers 10 with lid members 70 attached and container bodies 11.

[0026] 8, in the container 10 with the inner lid 50 and lid member 70 attached, the annular ridge 74 of the lid member 70 faces the corner bulge 51L of the inner lid 50 from the outside, which also prevents the lid member 70 from shifting sideways. There are also gaps between the lower end of the annular ridge 74 of the lid member 70 and the upper surface of the inner lid 50, and between the corner bulge 51L of the inner lid 50 and the lower surface of the lid member 70, so that the inner lid 50 and the lid member 70 do not come into contact in the vertical direction when attached to the container body 11. This prevents the weight of the lid member 70 from being applied to the inner lid 50, making the inner lid 50 less likely to break.

[0027] Furthermore, the lower end of fitting wall 75 of lid member 70 is located midway between upper end flange 15 and second intermediate flange 17, and higher than the lower end of inner lid 50. As a result, even when lid member 70 is attached, the outer surface of engagement protrusion 52 of inner lid 50 (outer surface of hanging wall 52B) is exposed.

[0028] Also, as shown in Figures 13 and 14, when the lid member 70 is placed on top of the inner lid 50, the annular protrusion 74 of the lid member 70 abuts against the upper surface of the inner lid 50, and the corner bulge portion 51L of the inner lid 50 abuts against the lower surface of the lid member 70.

[0029] Next, the effects of the container 10 of this embodiment will be described. As described above, in the container 10 of this embodiment, the inner lid 50 is attached to the container 10 in addition to the lid member 70, so that even if the lid member 70 is accidentally removed, the intrusion of foreign matter is prevented. Furthermore, if it is desired to reduce the height of the container 10, it is possible to use only the inner lid 50.

[0030] Generally, an inner lid that fits inside the container body 11 cannot be removed without inserting a hand inside the container body 11. However, according to this embodiment, the engaging protrusion 52 of the inner lid 50 protrudes from the notch 25 of the container body 11. Therefore, the inner lid 50 can be removed by operating the engaging protrusion 52 from outside the container body 11. Specifically, there is a space between the engaging protrusion 52 and the first intermediate flange 16, exposing the underside of the engaging protrusion 52. Therefore, the inner lid 50 can be lifted by pushing up the engaging protrusion 52. Furthermore, if the gap between the outer edge of the inner lid 50 and the inner surface of the container body 11 is small and it is difficult to insert a finger or the like, removing the inner lid 50 can be difficult. However, according to this embodiment, the inner lid 50 can be easily removed by operating the engaging protrusion 52. The inner lid 50 can be lifted by a worker or a work robot.

[0031] The engaging protrusions 52 protruding from the cutouts 25 are surrounded on three sides by the corner side vertical ribs 19, the intermediate vertical ribs 20, and the first intermediate flange 16, preventing the inner lid 50 from being unintentionally lifted due to a worker or an object coming into contact with the engaging protrusions 52. Furthermore, the engaging protrusions 52 do not protrude beyond the first intermediate flange 16 over the entire rattle range of the inner lid 50, and are also unlikely to protrude beyond the portion of the corner side vertical ribs 19 above the second intermediate flange 17 and the portion of the intermediate vertical rib 20 above the first intermediate flange 16, making it difficult for workers or surrounding objects to get caught on the engaging protrusions 52.

[0032] Here, the inner lid 50 may be removed after removing the lid member 70. However, it is also possible to lift the inner lid 50 with the lid member 70 still attached and remove the lid member 70 and the inner lid 50 simultaneously. In the latter case, the time required to remove the lid member 70 and the inner lid 50 is reduced. Furthermore, when the inner lid 50 is lifted with the lid member 70 still attached and the lid member 70 overlaps the inner lid 50, the annular protrusion 74 of the lid member 70 abuts the upper surface of the inner lid 50 and the corner bulge 51L of the inner lid 50 abuts the lower surface of the lid member 70, thereby distributing the load on the inner lid 50. Furthermore, because the corner bulge 51L is fitted into the annular protrusion 74, the lid member 70 is prevented from slipping off when the lid member 70 and the inner lid 50 are lifted. Even if the annular protrusion 74 is not provided, the lower end of the fitting wall 75 of the lid member 70 faces the outer surface of the inner lid 50, and the two abut and prevent slipping off.

[0033] Furthermore, when the inner lid 50 and the lid member 70 are attached to the container body 11, the lower end of the mating wall 75 of the lid member 70 is positioned above and near the lower end of the inner lid 50, and the outer surface (outer surface of the hanging wall 52B) of the engaging protrusion 52 of the inner lid 50 is exposed, so that the engaging protrusion 52 can be seen from the outside, making removal easier.

[0034] [Other embodiments] In the above embodiment, two notches 25 are provided on each of the pair of first side walls 13, but one or three or more notches 25 may be provided on each of the pair of first side walls 13, or the number of notches 25 may differ between the pair of first side walls 13. Notches 25 may also be formed on the second side wall 14.

[0035] In the above embodiment, the number of engaging protrusions 52 is the same as the number of cutouts 25, but it may be less than the number of cutouts 25. For example, it is conceivable to provide cutouts 25 in positions on the second side wall 14 that overlap with the engaging protrusions 52 when the inner lid 50 is rotated 90°, thereby increasing the number of orientations in which the inner lid 50 can be attached.

[0036] The planar shape of the container 10 may be rectangular, another polygonal shape, or circular.

[0037] 15A, the bottom surface of the cutout 25 may be extended outward, for example, so that the lower surface of the engagement protrusion 52 is not exposed. In this case, it is preferable to provide a finger hook 52K such as a recess or protrusion on the side surface of the engagement protrusion 52. Even if a finger hook is not provided, the inner lid 50 can be lifted by pressing a finger against the side surface of the engagement protrusion 52 and rotating it upward, thereby creating a gap between the engagement protrusion 52 and the bottom surface of the cutout 25.

[0038] When attached to the container body 11, the inner lid 50 and the lid member 70 may be configured to abut against each other in the vertical direction.

[0039] In the above embodiment, the inner lid 50 was supported around its entire circumference by the step portion 26, including the bottom surface of the cutout portion 25. However, the bottom surface of the cutout portion 25 may be positioned below the step portion 26, and the step portion 26 may support only the outer edge of the inner lid 50 excluding the engaging protrusion 52, or the step portion 26 may not be formed, and the inner lid 50 may be supported only by the bottom surface of the cutout portion 25.

[0040] The configuration may be such that only the inner lid 50 is provided without the lid member 70 .

[0041] In the above embodiment, the "fitting member" was the inner lid 50 that closes the upper end opening of the container body 11, but it may also be, for example, a partition member that is arranged in the vertical middle position of the container body 11 and divides the inside of the container into upper and lower sections, or a partition member that divides the inside of the container horizontally by integrally molding vertical and horizontal partition plates or by integrally molding multiple storage sections that extend vertically. Also, it may be a partition plate that spans between opposing side walls and divides the inside of the container horizontally, or a bar member that extends horizontally.

[0042] Although not included in the scope of the claims, a connecting wall 40 (see FIG. 15B) may be provided that connects the outer ends of the corner side vertical ribs 19 and the intermediate vertical ribs 20 and covers the engaging protrusions 52 from the outside. That is, as shown in FIG. 15B, a groove 41 that can receive the engaging protrusions 52 may be provided on the inner surface of the first side wall 13. Even in this case, the lower surface of the engaging protrusions 52 is exposed, so that the lower surface of the engaging protrusions 52 is pushed up to create a gap between the first side wall 13 and the engaging protrusions 52, and the inner lid 50 can be removed by inserting a finger into the lower surface of the engaging protrusions 52 through the gap. This allows the inner lid 50, which fits inside the container body 11, to be smoothly removed.

[0043] <Additional Notes> The following describes the group of features extracted from the above embodiment, while indicating, as necessary, the effects, etc. Note that, for ease of understanding, the corresponding configurations in the above embodiment are indicated in parentheses as appropriate below, but these group of features are not limited to the specific configurations indicated in parentheses.

[0044] [Feature 1] A container body (11) with an open top, a fitting member (50) that fits inside the container body (11); a notch (25) formed in the side wall (13) of the container body (11) and cut out from the upper end to a midpoint in the vertical direction; an engaging protrusion (52) that protrudes laterally from the outer edge of the fitting member (50) and is received in the notch (25); A container (10) comprising:

[0045] According to the container of feature 1, the engaging protrusion of the fitting member is exposed through the cutout, so that the fitting member can be removed by operating the engaging protrusion from outside the container body.

[0046] [Feature 2] The container (10) according to Feature 1, wherein the engaging protrusion (52) protrudes from the notch (25) and has an exposed lower surface.

[0047] In the container of feature 2, the lower surface of the engaging protrusion is exposed, so that the fitting member can be removed by pushing up the engaging protrusion from below.

[0048] [Feature 3] The container (10) according to Feature 1, further comprising a mounting portion (26) formed on the inner surface of the container body (11) on which the outer edge of the fitting member (50) is placed.

[0049] [Feature 4] 4. The container (10) according to Feature 3, wherein the placement portion (26) and the bottom surface of the notch (25) are arranged in the same plane.

[0050] The fitting member may be supported by the bottom surface of the cutout, or may be supported by a mounting portion formed on the inner surface of the container body as in Feature 3. Furthermore, as in Feature 4, the mounting portion and the bottom surface of the cutout may be arranged in the same plane, and the fitting member may be supported by both the mounting portion and the bottom surface of the cutout. In this case, the fitting member is stably supported.

[0051] [Feature 5] The container (10) according to Feature 4, further comprising a reinforcing rib (26) that is continuous with the mounting portion (26) and protrudes outward from the lower edge portion of the notch (25) on the side wall of the container body (11).

[0052] According to the container of feature 5, the bottom surface of the notch is reinforced, making it less likely to break.

[0053] [Feature 6] The container body (11) is provided on its outer surface with a pair of vertical ribs (19, 20) that protrude from both side edges of the notch (25) and extend downward from the notch (25), and a horizontal rib (16) that connects the pair of vertical ribs (19, 20) and faces the lower surface of the engaging protrusion (52) with a space therebetween, The container (10) according to Feature 2, wherein the engaging protrusion (52) does not protrude beyond at least one of the pair of vertical ribs (19, 20) and the horizontal rib (16) in the inward and outward direction of the container.

[0054] According to the container of feature 6, the engaging protrusion and the space below it are surrounded by a pair of vertical and horizontal ribs, preventing the engaging protrusion from being hit by an operator's hand or an object and causing the engaging member to be unintentionally lifted.

[0055] [Feature 7] a lid member (70) for closing the upper end opening of the container body (11); The container (10) according to any one of Features 1 to 6, wherein the fitting member (50) and the lid member (70) are provided with restricting portions (74, 51L) that engage with each other to restrict lateral displacement when the fitting member (50) is lifted and abuts against the lid member (70).

[0056] [Feature 8] The restricting portion (74, 51L) includes a first protrusion (51L) protruding from an upper surface of the fitting member (50) and a second protrusion (74) protruding from a lower surface of the cover member (70), The container (10) according to Feature 7, wherein the first protrusion (51L) is capable of abutting the lower surface of the lid member (70) and the second protrusion (74) is capable of abutting the upper surface of the fitting member (50).

[0057] According to the container of Feature 7, when the fitting member is lifted, the restricting portion engages to prevent the lid member from slipping off. The restricting portion may be configured, for example, such that a hanging wall hanging from the outer edge of the lid member fits onto the outside of the fitting member, or as in Feature 8, such that protrusions protruding from the upper surface of the fitting member and the lower surface of the lid member engage with each other.

[0058] In addition, in the container of feature 8, the first protrusion abuts against the lower surface of the lid member and the second protrusion abuts against the upper surface of the fitting member, so that when the lid member overlaps the fitting member, the load received by the fitting member is distributed.

[0059] [Feature 9] a lid member (70) for closing the upper end opening of the container body (11); A container (10) according to any one of features 1 to 8, wherein when the fitting member (50) and the lid member (70) are installed on the container body (11), the fitting member (50) and the lid member (70) are spaced apart from each other.

[0060] [Feature 10] 10. The container (10) according to Feature 9, wherein the fitting member (50) and the lid member (70) have abutment portions (74, 51L) that abut against each other when the fitting member (50) is lifted.

[0061] According to the container of Feature 9, when the container is installed on the container body, the fitting member is not subjected to the load of the lid member, making the fitting member less likely to break. Also, according to the container of Feature 10, when the fitting member is lifted, the contact portions come into contact with each other, lifting the lid member as well, and both can be removed.

[0062] [Feature 11] a lid member (70) having a lid fitting wall (75) that fits onto the outside of the container body (11); A container (10) according to any one of features 1 to 10, wherein the lower end of the lid fitting wall (75) is located above the lower end of the engagement protrusion (52).

[0063] According to the container of feature 11, at least a part of the engaging protrusion is located below the lid fitting wall of the lid member, so that it is visible from the outside, facilitating the removal operation.

[0064] [Feature 12] A container comprising a container body (11) with an open top end and a fitting member (50) that fits inside the container body (11), an engaging protrusion (52) protruding laterally from the outer edge of the fitting member (50); a receiving portion (25) provided on the side wall of the container body (11) and capable of receiving the engaging protrusion (52), The container (10) has a through-portion (25) in which the receiving portion (25) penetrates a portion of the side wall (13) of the container body (11) and exposes a portion of the engaging protrusion (52).

[0065] Although the present specification and drawings disclose specific examples of the technology included in the scope of the claims, the technology described in the claims is not limited to these specific examples, but also includes various modifications and variations of the specific examples, and also includes parts of the specific examples taken out alone.
