[0023] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0024] Fig. 1 shows a lid 100 of the present invention. Fig. 1(a) is an overall perspective view of the front side of the lid 100, and Fig. 1(b) is an overall perspective view of the back side of the lid 100.

[0025] As shown in FIG. 1, the lid 100 is a generally rectangular flat plate made of synthetic resin, and includes a flat top plate 110, side walls 120 rising upward from the outer periphery 111 of the top plate 110, and flange portions 130 extending outward from the side walls 120. The flange portions 130 on each side of the lid 100 are provided with recesses 140 recessed inward from the outer edge 101 of the lid 100. Furthermore, protrusions 150 protruding downward from the rear surface of the flange portions 130 are provided on both ends of the recesses 140. Note that there is a gate mark at a given location (for example, near the center) on the top plate 110, which was left when the lid 100 was injection molded (the gate mark is not shown in the drawing).

[0026] As will be described later, the protrusions 150 are portions that engage with a portion of the container body to which the lid body 100 is attached, and are fixing portions that fix the position and posture of the lid body 100 so that the lid body 100 does not slip off the container body. The protrusions 150 are provided on both ends of the recess 140, but are not limited to this and can be provided at any position on the lid body 100 as long as they can engage with a portion of the container body to which the lid body 100 is attached.

[0027] Furthermore, the recesses 140 are provided at positions corresponding to the recesses of the container body to which the lid body 100 is attached, and are configured so that when the lid body 100 is attached to the container body, the recesses 140 of the lid body 100 and the recesses of the container body are stacked vertically. Note that, although the recesses 140 are provided on each side of the lid body 100, this is not limitative, and any number of recesses may be provided at any positions as long as the lid body 100 is provided at positions corresponding to the recesses of the container body.

[0028] Next, a container body 200 of the present invention is shown in Fig. 2. Fig. 2(a) is an overall perspective view of the container body 200, and Fig. 2(b) is a plan view of the container body 200.

[0029] As shown in FIG. 2, the container body 200 is made of synthetic resin and has a generally rectangular parallelepiped shape. The container body 200 includes a flat bottom wall 210, side walls 220 rising upward from the outer periphery 211 of the bottom wall 210, and flange portions 230 extending outward from the upper ends 221 of the side walls 220. The flange portions 230 include a flat front flange surface 231 on the front side and a flat back flange surface 232 on the back side, with the front flange surface 231 and the back flange surface 232 being parallel to each other. The flange portions 230 on each side of the container body 200 are provided with recesses 240 recessed inward from the outer edge 201 of the container body 200. Note that a gate mark from injection molding the container body 200 is present at a given location (e.g., near the center) on the bottom wall 210 (the gate mark is not shown in the drawing).

[0030] The container body 200 has an opening 290 that opens upward, allowing contents to be placed inside. The flange portion 230 is provided so as to be continuous in the circumferential direction around the periphery of the opening 290. A recess 222 that is recessed inward is provided in a portion of the side wall 220. Furthermore, since the entire side wall 220 of the container body 200 is configured with an uneven shape due to the recess 222, and rigidity is improved, it is not necessary to provide vertical ribs on the side wall 220 to improve rigidity.

[0031] Next, Fig. 3 shows a state in which the lid body 100 is attached to the container body 200. Fig. 3(a) is a plan view of the container body 200 in a state in which the lid body 100 is attached, and Fig. 3(b) is a cross-sectional view taken along the line AA.

[0032] As shown in FIG. 3 , the lid 100 is attached to the container body 200 so as to cover the opening 290. The flange 130 of the lid 100 rests on the front flange surface 231 of the flange 230 of the container body 200, so the lid 100 is stably attached to the container body 200 in a horizontal position. Furthermore, the side wall 120 of the lid 100 is positioned inside the upper end 221 of the side wall 220 of the container body 200, so the lid 100 is less likely to slip off the container body 200. Furthermore, the protrusion 150 of the lid 100 engages with the recess 240 of the container body 200. Therefore, the position and orientation of the lid 100 are fixed so that the lid 100 does not slip off the container body 200. The protrusion 150 is positioned inside the outer circumferential edge of the flange 130 of the container body 200. The recess 140 of the lid 100 and the recess 240 of the container body 200 are vertically overlapped. The outer periphery of the flange 230 of the container body 200 and the outer periphery of the flange 130 of the lid 100 are aligned at the same vertical position.

[0033] Next, Figures 4 and 5 show a container body 300 of the present invention. The container body 300 has a smaller storage volume than the container body 200 shown in Figure 2, and has a lid 400 attached thereto so that it can be opened and closed. Note that Figure 4(a) is an overall perspective view of the container body 300 with the lid 400 closed, Figure 4(b) is an overall perspective view of the container body 300 with the lid 400 open, Figure 5(a) is a plan view of the container body 300 with the lid 400 closed, and Figure 5(b) is a cross-sectional view taken along line B-B.

[0034] 4, the container body 300 is made of synthetic resin and has a generally rectangular parallelepiped shape, and includes a flat bottom wall 310, side walls 320 rising upward from the outer periphery 311 of the bottom wall 310, and a flange portion 330 extending outward from the upper end 321 of the side wall 320. The flange portion 330 includes a flat front flange surface 331 on the front side and a flat back flange surface 332 on the back side, the front flange surface 331 and the back flange surface 332 being parallel to each other. The flange portion 330 on the front side of the container body 300 is provided with a recess 340 recessed inward from the outer edge 301 of the container body 300.

[0035] The container body 300 has an opening 390 that opens upward, allowing contents to be placed inside. The flange portion 330 is provided so as to continue circumferentially around the periphery of the opening 390. A recess 322 that is recessed inward is provided in a portion of the side wall 320. Furthermore, since the entire side wall 320 of the container body 300 is configured with an uneven shape due to the recess 322, which improves rigidity, it is not necessary to provide vertical ribs on the side wall 320 to improve rigidity.

[0036] The lid 400 is a generally rectangular flat plate made of synthetic resin, and includes a flat top plate 410, side walls 420 rising upward from the outer periphery 411 of the top plate 410, and a flange portion 430 extending outward from the side wall 420. The flange portion 430 on the front side of the lid 400 is provided with a recess 440 recessed inward from the outer edge 401 of the lid 400. The flange portion 430 on the rear side of the lid 400 is connected to the flange portion 330 of the container body 300 by a connecting portion 405 such as a hinge, and the lid 400 is attached to the container body 300 by the connecting portion 405 so as to be openable and closable.

[0037] Furthermore, a fixing member 380 is provided in the recess 340 on the front side of the container body 300 as a fixing portion for fixing the lid body 400. The fixing member 380 is flat and has axial holes 381 at both ends. By connecting the axial holes 381 of the fixing member 380 to the axial portions 348 provided at both ends of the recess 340, the fixing member 380 is axially supported so as to be rotatable about the axial portions 348. Note that the fixing member 380 is axially supported so as to be rotatable about the axial portions 348, but this is not limiting. For example, the fixing member 380 may be configured to slide up and down or left and right to fix and release the lid body 400. The fixing member 380 may have any configuration as long as it can fix and release the lid body 400.

[0038] As shown in FIG. 5(b), when the lid 400 is closed to cover the opening 390 of the container body 300, the flange portion 430 of the lid 400 rests on the front flange surface 331 of the flange portion 330 of the container body 300, so the lid 400 is stably closed in a horizontal position. In addition, the side wall 420 of the lid 400 is disposed inside the upper end 221 of the side wall 320 of the container body 300, so the lid 400 is less likely to slip off the container body 300. Furthermore, the convex locking portion 382 at the tip of the fixing member 380 engages with the recessed portion 435 of the flange portion 430. Therefore, the fixing member 380 fixes the lid 400 so that it does not open.

[0039] To open the lid 400, the fixing member 380 is rotated outward to disengage the locking portion 382 from the recess 435. This releases the fixing of the lid 400 by the fixing member 380, allowing the lid 400 to be opened. Furthermore, since the fixing member 380 is located in the recess 340, the fixing member 380 does not protrude outward from the outer edge 301 of the container body 300, ensuring a good fit. Furthermore, as will be described later, the fixing member 380 can be rotated even when the container body 300 is placed inside a storage container or in a narrow space such as near a wall. Furthermore, when the lid 400 is closed, the recess 440 of the lid 400 and the recess 340 of the container body 300 are vertically overlapped. Therefore, even when the lid 400 is fixed by the fixing member 380, the fixing member 380 is positioned in the recess 340 and the recess 440, and therefore the fixing member 380 does not protrude outward from the outer edge 301 of the container body 300 and the outer edge 401 of the lid 400, and fits snugly. The container body is not limited to the shape of the container body 200 shown in FIG. 2 or the shape of the container body 300 shown in FIG. 4. The container body may have any shape as long as it can be accommodated in the outer container described below and has a flange portion that can be placed on the placement portion of the outer container. The fixing portion is not limited to the shape of the protrusion 150 shown in FIG. 1 or the shape of the fixing member 380 shown in FIG. 4. The fixing portion may have any shape as long as it can fix the lid to the container body so as to prevent the position and posture of the lid from shifting.

[0040] Next, Fig. 6 and Fig. 7 show the outer container 500 of the present invention. Fig. 6(a) is an overall perspective view of the outer container 500, Fig. 6(b) is an overall perspective view of the outer container 500 with the handle 600 removed, Fig. 6(c) is an enlarged bottom view of the outer container 500, Fig. 6(d) is a vertical cross-sectional view of the hole 580 and the hole of the outer container 500, Fig. 7(a) is a side view of the periphery of the axial hole 560 of the outer container 500, and Fig. 7(b) is a side view of the axial portion 630 of the handle 600 as viewed from the inside.

[0041] 6(a), the outer container 500 is made of synthetic resin and has a generally rectangular parallelepiped shape, and includes a flat bottom wall 510, side walls 520 rising upward from the outer periphery 511 of the bottom wall 510, and a flat mounting portion 530 spreading outward from the upper end 521 of the side wall 520. The mounting portion 530 on each side of the outer container 500 is provided with a recess 540 recessed inward from the outer edge 501 of the outer container 500. Furthermore, a recess 540 is provided on the side to which a handle portion 600 (described later) is attached, so that the handle portion 600 does not interfere with the mounting portion 530, allowing the handle portion 600 to rotate smoothly.

[0042] 6(c), bottom wall 510 has a generally rectangular shape surrounded by long sides 512 and short sides 513, and legs 570 are provided at the four corners of bottom wall 510. Legs 570 protrude from the rear surface of bottom wall 510 and include a first leg 572 extending along long side 512 and a second leg 573 extending along short side 513. First leg 572 is formed in a sloped shape so that its height gradually decreases toward tip 574, and further has a shorter overall length than second leg 573. As will be described later, outer container 500 is placed on bottom wall 710 of storage container 700, and bottom wall 710 of storage container 700 has a sloped shape in which the area around outer periphery 711 bulges downward and gradually decreases in height. Since the legs 570 of the outer container 500 are placed near the outer periphery 711 of the bottom wall 710 of the storage container 700, by making the first legs 572 of the legs 570 shaped to correspond to the periphery of the outer periphery 711, which has a downwardly bulging shape, the outer container 500 can be placed stably on the bottom wall 710 of the storage container 700.

[0043] 6(d), a hole 580 is provided in the side wall 520 of the outer container 500. This hole 580 penetrates from the outer surface 525 to the inner surface 526 of the side wall 520, and the inner edge of the hole 580 includes an inwardly inclined portion 581 and a flat portion 582 that is continuous with the inclined portion 581 and extends horizontally. The inclined portion 581 of the hole 580 is textured (i.e., the surface of the inclined portion 581 is provided with a finely textured or wrinkled pattern), which improves the appearance of the area around the hole 580. The inclined portion 581 of the hole 580 is continuous with the outer surface 525 of the side wall 520, and the outer surface 525 of the side wall 520 is also textured. Therefore, the embossing is applied continuously from outer surface 525 of side wall 520 to inclined portion 581 of hole portion 580, which enhances the sense of unity in appearance from outer surface 525 of side wall 520 to hole portion 580. Note that the embossing may be applied across from outer surface 525 to inclined portion 581.

[0044] The outer container 500 has an opening 590 that opens upward, allowing the container body to be placed inside. This opening 590 can be closed with a lid 100, as shown in FIG. 6(b). The mounting portion 530 is provided so as to be continuous in the circumferential direction around the opening 590. A recess 522 that is recessed inward is provided in a portion of the side wall 520. Furthermore, since the entire side wall 520 of the outer container 500 is configured to have an uneven shape due to the recess 522, thereby improving rigidity, it is not necessary to provide vertical ribs on the side wall 520 for improving rigidity. The outer container 500 is not limited to the shape shown in FIG. 6 and may have any shape as long as it has the mounting portion 530 and can accommodate the container body.

[0045] As shown in FIG. 6 , the handle 600 is made of synthetic resin and is formed in a generally U-shape. The handle 610 includes a gripping portion 610 that a user grips when carrying the outer container 500, and connecting portions 620 at both ends of the handle 610 that connect the handle 600 to the outer container 500. A shaft 630 provided at the tip of the connecting portion 620 is connected to a shaft hole 560 provided in the side wall 520 of the outer container 500, thereby rotatably supporting the handle 600 in the shaft hole 560. The outside of the handle 610 has a recess 611. Therefore, as shown in FIG. 12( b ), which will be described later, when the outer container 500 is placed in the storage container 700, the recess 611 can be used to easily hook the handle 600 with one's fingers. The inside of the handle 610 has a protrusion 612, making it easy to grip, and the handle 610 is thick to improve its rigidity.

[0046] As shown in FIG. 7(b), the shaft 630 of the handle 600 includes a base 631 that protrudes from the inner surface of the tip of the connecting portion 620, and a head 632 at the tip of the base 631. The length L3 of the base 631 in the vertical direction (longitudinal direction) of the shaft 630 is longer than the width L4 of the base 631 in the horizontal direction (shortitudinal direction) of the shaft 630, so that the entire base 631 has a vertically elongated, generally rectangular shape. The head 632 is formed larger than the base 631 so as to protrude slightly laterally from the base 631. Therefore, when the shaft 630 is inserted into the shaft hole 560, the back surface of the head 632 engages with the outer edge of the shaft hole 560, preventing the shaft 630 from accidentally coming off the shaft hole 560. A protrusion 639 that protrudes from the inner surface of the tip of the connecting portion 620 is provided at a position adjacent to and below the shaft 630. Furthermore, a reinforcing rib 638 is connected to the upper part of the shaft portion 630 .

[0047] As shown in FIG. 7( a), the axial hole 560 of the outer container 500 includes a axial hole main body 561 that rotatably supports the base 631 of the axial portion 630 of the handle 600, and a axial stopper portion 562 above the axial hole main body 561. The width L2 of the axial stopper portion 562 is shorter than the width L1 of the axial hole main body 561, and the axial stopper portion 562 as a whole has a vertically elongated, approximately rectangular shape. As will be described later, the base 631 of the axial portion 630 can move from a state in which it is rotatably supported by the axial hole main body 561 to the axial stopper portion 562. Furthermore, a guide groove 563 having a substantially arc shape is provided around the periphery of the axial hole 560. Furthermore, an insertion groove 565 is provided between the guide grooves 563, with a step portion 564 sandwiched therebetween, and the insertion groove 565 communicates with the axial hole main body 561. A reinforcing rib 569 is connected to the outer periphery of the axial hole 560. As will be described later, when the handle portion 600 is rotated vertically to lift the outer container 500, the axial hole 560 connected to the handle portion 600 is reinforced so as to withstand external forces such as the weight of the outer container 500.

[0048] Next, Fig. 8 shows how to use the handle 600. Fig. 8(a) is a side view of the handle 600 in a lying position, Fig. 8(b) is a side view of the handle 600 in a vertically rotated position, and Fig. 8(c) is a side view of the handle 600 in a lifted position.

[0049] As shown in FIG. 8( a), the base 631 of the shaft 630 of the handle 600 is rotatably connected to the shaft hole main body 561 of the shaft hole 560 of the outer container 500, and the handle 600 is rotated to a horizontally laid position. By laying the handle 600 horizontally, it is possible to prevent the handle 600 from getting in the way when, for example, placing the outer container 500 in another storage container. Furthermore, when the shaft 630 is rotatably connected to the shaft hole 560, the protrusion 639 adjacent to the shaft 630 is positioned within the guide groove 563. Therefore, because the protrusion 639 is engaged with the guide groove 563, the base 631 of the shaft 630 does not come off the shaft hole main body 561 of the shaft hole 560, and the handle 600 can be rotated smoothly.

[0050] 8(b), the handle 600 is gripped and rotated vertically in order to lift or carry the outer container 500. At this time, as the shaft 630 rotates, the protrusion 639 moves downward within the guide groove 563. Then, the protrusion 639 moves from the guide groove 563 over the step 564 and into the insertion groove 565.

[0051] Next, as shown in FIG. 8( c), when the handle 600 is further lifted upward, the base 631 of the shaft 630 moves from the shaft hole main body 561 of the shaft hole 560 to the shaft stopper 562. At this time, the protrusion 639 can move from the insertion groove 565 toward the shaft hole main body 561, so it does not interfere with the movement of the base 631 to the shaft stopper 562. Then, when the base 631 of the shaft 630 moves from the shaft hole main body 561 of the shaft hole 560 to the shaft stopper 562, the vertically elongated base 631 fits into the vertically elongated shaft stopper 562, which has a shape corresponding to the base 631, so that the shaft 630 is fixed so as not to rotate within the shaft hole 560. In this way, the rotation of the handle 600 can be restricted, making it easier to lift and transport the outer container 500. If the guide groove 563 and the insertion groove 565 are not provided, a protrusion 639' may be provided extending from below the shaft portion 630 toward the tip of the connecting portion 620, as shown in FIG. 7(b). The protrusion 639' is connected to the shaft portion 630 to reinforce the shaft portion 630. Furthermore, as shown in FIG. 8(c), when the handle portion 600 is lifted vertically, the protrusion 639' enters the shaft hole main body 561 of the shaft hole 560 from the outside to the inside, and the lower end of the protrusion 639' can abut against the inner surface of the shaft hole main body 561 of the shaft hole 560. Therefore, the frictional force generated when the protrusion 639' abuts makes it difficult for the protrusion 639' to move relative to the shaft hole main body 561, and as a result, the handle portion 600 is maintained in a vertically standing state.

[0052] Next, a container assembly P1 including a container body 200 and an outer container 500 will be described with reference to Fig. 9. Fig. 9(a) is an overall perspective view of the container assembly P1, Fig. 9(b) is a plan view of the container assembly P1, and Fig. 9(c) is a cross-sectional view taken along the line CC.

[0053] 9 , in the assembled container P1, the container body 200 with the lid 100 attached is housed inside the outer container 500 so as to cover the opening 590 of the outer container 500. At this time, since the flange portion 230 of the container body 200 is placed on the mounting portion 530 of the outer container 500, the container body 200 is housed in a stable position. Furthermore, since the flange portion 230 of the container body 200 is placed on the mounting portion 530 of the outer container 500, the bottom wall 210 of the container body 200 is housed in a state where it is floating above the bottom wall 510 of the outer container 500. Therefore, with the container body 200 housed in the outer container 500, the space X1 created on the bottom wall 510 side of the outer container 500 can be used effectively, for example, to house items in the space X1.

[0054] Furthermore, even when the container body 200 is housed in the outer container 500, the protrusion 150 is exposed to the outside, making it easy to hook a finger on the protrusion 150 and remove the lid body 100. Furthermore, since the protrusion 150 is located in the recess 140 of the lid body 100, a user can easily hook a finger on the protrusion 150 using the recess 140, making it easy to remove the lid body 100. Note that when the container body 200 with the lid body 100 attached is housed in the outer container 500, the recess 140 of the lid body 100, the recess 240 of the container body 200, and the recess 540 of the outer container 500 are vertically overlapping, making it easy to hook a finger on the protrusion 150. Furthermore, in the container assembly P1, the lid body 100 can be attached optionally. Furthermore, as shown in FIG. 9(c), the flange portion 230 of the container body 200 is formed in a U-shaped cross section with flange surfaces on the top and bottom, making it easy to hook a finger. 9(c), the outer periphery of the lid 100, the outer periphery of the flange 230 of the container body 200, and the outer periphery of the outer container 500 are aligned vertically, but this is not limiting. The outer periphery of the lid 100 and the outer periphery of the flange 230 of the container body 200 may be made to protrude outward beyond the outer periphery of the outer container 500 to make it easier to hook fingers.

[0055] Next, Fig. 10 illustrates a container assembly P2 including a container body 300 and an outer container 500. Fig. 10(a) is an overall perspective view of the container assembly P2, Fig. 10(b) is a plan view of the container assembly P2, and Fig. 10(c) is a cross-sectional view taken along the line DD.

[0056] As shown in FIG. 10 , in the container assembly P2, the container body 300 is housed inside the outer container 500 so as to cover the opening 590 of the outer container 500. At this time, the flange portion 330 of the container body 300 is placed on the mounting portion 530 of the outer container 500, so the container body 300 is housed in a stable position. Furthermore, because the flange portion 330 of the container body 300 is placed on the mounting portion 530 of the outer container 500, the bottom wall 310 of the container body 300 is housed in a state where it is floating above the bottom wall 510 of the outer container 500. Therefore, with the container body 300 housed in the outer container 500, the space X2 formed on the bottom wall 510 side of the outer container 500 can be used effectively, for example, to house items in the space X2. Two container bodies 300 are housed in the outer container 500, and each container body 300 is arranged so that the fixing member 380 faces outward.

[0057] 10 , even when the container body 300 is housed in the outer container 500, the fixing member 380 can be operated, allowing the lid 400 to be fixed and released by the fixing member 380, thereby opening and closing the lid 400. Furthermore, because the fixing member 380 is disposed in the recess 340 of the container body 300, a user can easily place their finger on the fixing member 380 using the recess 340, making it easy to operate the fixing member 380. Furthermore, because the fixing member 380 is disposed on the flange portion 330, the fixing member 380 is not hidden by the outer container 500 even when the container body 300 is housed in the outer container 500, making it easy for the user to operate the fixing member 380. Furthermore, when the container body 300 is housed in the outer container 500, the recess 340 of the container body 300 and the recess 540 of the outer container 500 are vertically overlapping, making it easy to place their finger on the fixing member 380.

[0058] Next, a storage container 700 of the present invention is shown in Figure 11. Figure 11(a) is an overall perspective view of the storage container 700, and Figure 11(b) is a plan view of the storage container 700.

[0059] As shown in FIG. 11 , storage container 700 is made of synthetic resin and has a generally rectangular parallelepiped shape, and includes a flat bottom wall 710 and side walls 720 that rise upward from an outer periphery 711 of bottom wall 710. An opening 790 is formed at the top, and other containers can be placed inside storage container 700 through opening 790. Furthermore, a partition rib 725 is provided on the inside of side wall 720 for attaching a partition member that can be installed inside storage container 700. This partition rib 725 protrudes from the inner surface of side wall 720. Note that storage container 700 is not limited to the shape shown in FIG. 11 , and may have any shape as long as it can accommodate a set of containers.

[0060] 12 and 13 show the state in which the set of containers P1 and P2 are stored in the storage container 700. Note that Fig. 12(a) is an overall perspective view of the storage container 700, Fig. 12(b) is a plan view of the storage container 700, Fig. 13(a) is a cross-sectional view taken along line E-E in Fig. 12, and Fig. 13(b) is a cross-sectional view taken along line F-F in Fig. 12.

[0061] 12, the container set P1 and the container set P2 are accommodated inside the storage container 700 through an opening 790 of the storage container 700. The accommodated container set P1 and container set P2 are arranged side by side and placed on the bottom wall 710 of the storage container 700. In addition, recesses 522 are provided in the side walls 520 of the container set P1 and container set P2, so that the container set P1 and container set P2 can be securely accommodated without interfering with the partition rib 725 on the inner surface of the side wall 720. Note that, as will be described later, even when the container body 200 is directly accommodated in the storage container 700, the container set P1 and container set P2 can be securely accommodated without interfering with the partition rib 725 on the inner surface of the side wall 720, because the recesses 222 are provided in the side wall 220 of the container body 200.

[0062] 13(a), even when the set container P1 and the set container P2 are stored in the storage container 700, the recess 340 of the set container P2 does not get partially caught by the adjacent set container P1, and space for the recess 340 is secured, so that a user can easily use the recess 340 to hook their fingers on the fixing member 380 and easily operate the fixing member 380. Furthermore, as shown in FIG. 13(a), the recess 340 of the set container P2 and the recesses 140 and 240 of the set container P1 are arranged to face each other, so that a user can easily use the recess 140 and 240 of the set container P1 to hook their fingers on the fixing member 380 and easily operate the fixing member 380. Furthermore, as shown in FIG. 13(b), a small gap is provided between the recess 340 of the set container P2 and the side wall 720 of the opposing storage container 700, ensuring sufficient space for the recess 340, making it easy for the user to use the recess 340 to hook their fingers on the fixing member 380 and operate the fixing member 380.

[0063] 13(a), even when the container set P1 and the container set P2 are stored in the storage container 700, the recesses 140 and 240 of the container set P1 do not become partially filled with the adjacent container set P2, and the spaces between the recesses 140 and 240 are secured, so that a user can easily use the recesses 140 and 240 to hook their fingers on the protrusions 150 and remove the lid 100. Furthermore, as shown in FIG. 13(a), the recesses 340 of the container set P2 and the recesses 140 and 240 of the container set P1 are arranged to face each other, so that a user can easily use the recesses 340 of the container set P2 to hook their fingers on the protrusions 150 and remove the lid 100. Furthermore, as shown in Figure 13(a), there is a small gap between the recesses 140 and 240 of the set container P1 and the side wall 720 of the opposing storage container 700, so that the space for the recesses 140 and 240 is reliably secured, and the user can easily use the recesses 140 and 240 to hook their fingers on the protrusions 150, making it easy to remove the lid body 100.

[0064] 12 and 13, a set of containers P1 and a set of containers P2 are used as the containers to be accommodated in the storage container 700, but this is not limiting. For example, a container body 200 with a lid 100 attached may be used as the container to be accommodated in the storage container 700. In this case, a plurality of container bodies 200 with lids 100 attached can be stacked and accommodated inside the storage container 700 through the opening 790 of the storage container 700. Furthermore, the recesses 140 and 240 of one adjacent container body 200 do not become partially embedded in the recesses 140 and 240 of the other adjacent container body 200, ensuring sufficient space for the recesses 140 and 240. Furthermore, a small gap is provided between the recesses 140 and 240 of the container body 200 and the opposing sidewall 720 of the storage container 700, ensuring sufficient space for the recesses 140 and 240. Therefore, a user can easily place his / her fingers on the protrusions 150 using the recesses 140 and 240, and the protrusions 150 can fix and release the lid 100.

[0065] Furthermore, the container body 300 may be used as a container to be accommodated in the storage container 700. In this case, multiple container bodies 300 can be accommodated in a stacked state inside the storage container 700 through the opening 790 of the storage container 700. Furthermore, a portion of the container body 300 does not get into the recess 340 of one adjacent container body 300, ensuring sufficient space for the recess 340. Furthermore, a slight gap is provided between the recess 340 of the container body 300 and the opposing side wall 720 of the storage container 700, ensuring sufficient space for the recess 340. Therefore, a user can easily place their finger on the fixing member 380 using the recess 340, enabling the fixing member 380 to fix and release the lid 400.

[0066] Furthermore, the container body 200 with the lid body 100 and the container body 300 may be used as the containers to be housed in the storage container 700. In this case, in FIGS. 12 and 13 , with the outer container 500 removed, the container body 200 with the lid body 100 and the container body 300 are directly housed in the storage container 700. In this case, the arrangement of the container body 200 with the lid body 100 and the container body 300 is basically the same as in FIGS. 12 and 13 . Therefore, a user can easily place their fingers on the protrusions 150 using the recesses 140 and 240, thereby enabling the protrusions 150 to fix and release the lid body 100. Furthermore, a user can easily place their fingers on the fixing member 380 using the recesses 340, enabling the fixing member 380 to fix and release the lid body 400.
