[0024] Embodiments of the present invention will be described below with reference to the drawings. In this specification, "upward" refers to the direction that points upward in the vertical direction when the container body is placed on a horizontal surface with its opening facing upward, and "downward" refers to the direction that points downward in the vertical direction.

[0025] Figures 1 to 6 show the assembled container 900 of the present invention. Figure 1 is an exploded perspective view of the assembled container 900, Figure 2(a) is a plan view of the container body 100, Figure 2(b) is an AA end view, Figure 2(c) is a B-B end view, Figure 2(d) is an enlarged AA end view of the area around the upper end 121 of the side wall 120, Figure 3(a) is an enlarged perspective view of the area around the shaft portion 330 of the handle portion 300, and Figure 3(b) is an axial hole 13 of the container body 100. Figure 4(a) is a side view of the area around 0, Figure 4(b) is a perspective view of the top side of the lid 400, Figure 5(a) is a perspective view of the outside of the inner container 200, Figure 5(b) is a perspective view of the inside of the inner container 200, Figure 6(a) is a plan view of the inner container 200, Figure 6(b) is a side view of the inner container 200, and Figure 6(c) is a C-C end view.

[0026] As shown in Figure 1, the assembled container 900 comprises a container body 100, an inner container 200 housed in the container body 100, a handle portion 300 rotatably attached to the inner container 200, and a lid 400 that can close the opening of the container body 100 when the inner container 200 is housed inside the container body 100.

[0027] As shown in Figures 1 and 2, the container body 100 is a roughly rectangular parallelepiped made entirely of synthetic resin and comprises a bottom wall 110, side walls 120 rising from the bottom wall 110, an opening 103 with an opening at the upper end 121 of the side wall 120, and a storage space 101 enclosed by the bottom wall 110 and the side wall 120. The upper end 121 of the side wall 120 is provided with a flat flange portion 140 and a flat container body side mounting portion 150 on the lower inside of the flange portion 140, so that the inside of the upper end 121 of the side wall 120 is stepped due to the flange portion 140 and the container body side mounting portion 150. Furthermore, an outward-extending overhang portion 141 is provided on the outside of the flange portion 140, and an inclined portion 151 that slopes inward and downward is provided on the inside of the container body side mounting portion 150. Furthermore, the flange portion 140 and the container body side mounting portion 150 are provided continuously or intermittently in the circumferential direction of the container body 100.

[0028] Furthermore, as shown in Figure 2, a handle portion 111 that is recessed inward is provided at any point on the bottom wall 110 (for example, inside the outer rib of the bottom wall 110). By placing their fingers on the handle portion 111 from below, users can easily lift and tilt the container body 100, making it easier to discharge the contents stored in the storage space 101 of the container body 100 to the outside.

[0029] Furthermore, as shown in Figure 2, a protrusion 123 is provided on the inside of the side wall 120. As shown in Figure 2(a), this protrusion 123 is partially positioned in a plan view so as to be close to the center line passing through the center O of the container body 100 (which coincides with the B-B end face line). The protrusion 123 is provided on the side wall 120 where the center line passing through the center O of the container body 100 is located, and is not provided on the side wall 120 (the left and right side walls 120 in Figure 2(a)) that is far from the center line passing through the center O of the container body 100 (which coincides with the B-B end face line). Although the protrusion 123 extends in a long shape in a plan view as shown in Figure 2(a), it is not limited to this, and the protrusion 123 may be any shape, such as a short projection, as long as the stepped portion 229 of the inner container 200, which will be described later, can be placed on it, in order to secure a wide storage space 101. Furthermore, the protrusion 123 improves the strength of the side wall 120 of the container body 100, and in particular, improves the strength of the side wall 120 in the middle portion in the height direction of the container body 100. Also, the amount of protrusion of the protrusion 123 is greater than the amount of protrusion of the nesting step 124 when the container bodies 100 are stacked. In addition, as shown in Figure 2(a), the total length of the protrusion 123 in a plan view is less than half the length of the outer circumference of the container body 100. Moreover, the protrusion 123 is formed on the straight portion of the container body 100.

[0030] Furthermore, as shown in Figures 1 and 3, the handle portion 300 is made entirely of synthetic resin and has a roughly U-shape, comprising a grip portion 310 that the user holds with their hand, and connecting portions 320 on both sides of the grip portion 310. The connecting portion 320 is the part that connects to the container body 100 and has a shaft portion 330 at its tip. As shown in Figure 3(a), the shaft portion 330 comprises a shaft body 331 that protrudes from the inner surface 321 of the connecting portion 320, a head portion 332 at the tip of the shaft body 331, and a projection portion 333 that protrudes laterally from the head portion 332. In addition, a projection portion 339 is provided adjacent to the shaft portion 330, protruding from the inner surface 321 of the connecting portion 320.

[0031] On the other hand, as shown in Figures 1 and 3, the container body 100 is provided with an axial hole 130 in the overhanging portion 141 of the upper end 121 of the side wall 120. The axial hole 130 has a central hole 132 through which the head 332 of the shaft portion 330 can be inserted, and a side hole 133 extending laterally from the central hole 132 through which the protruding portion 333 of the shaft portion 330 can be inserted, and has a shape at least equivalent to that of the shaft portion 330 so that the shaft portion 330 can be inserted. Furthermore, as long as the axial hole 130 has a central hole 132 and a side hole 133, it can have any shape, such as by adding other holes.

[0032] When the handle portion 300 is laid horizontally (rotated 90 degrees from the state shown in Figure 3), the shaft portion 330 of the handle portion 300 and the shaft hole 130 of the container body 100 are in the same position. Therefore, the shaft portion 330 can be inserted into the shaft hole 130 and supported, and the handle portion 300 can be easily connected to the container body 100. Furthermore, since the outer overhang portion 141 is separated from the outer surface of the side wall 120, there is a space 142 on the back side of the outer overhang portion 141. As a result, the shaft portion 330, which is inserted into and supported in the shaft hole 130, can rotate freely within the space 142 on the back side of the shaft hole 130, and the protruding portion 333 of the shaft portion 330 abuts against the back surface of the outer overhang portion 141 around the shaft hole 130, so the shaft portion 330 does not come out of the shaft hole 130 unintentionally. Thus, since the shaft hole 130 has the same shape as the shaft portion 330, there is no need to forcibly fit and connect the shaft portion 330 and the shaft hole 130 when supporting the shaft portion 330 in the shaft hole 130, thereby preventing deformation and whitening of the shaft portion 330 and the shaft hole 130.

[0033] Furthermore, adjacent to the shaft hole 130, a restricting portion 139 is provided below the central hole 132, projecting outward from the outer overhang portion 141. Therefore, when the handle portion 300 is laid horizontally, the projection 339 of the handle portion 300 and the restricting portion 139 of the container body 100 come into contact, allowing the handle portion 300 to be fixed in a horizontal position. In addition, when the handle portion 300 is laid horizontally, other components such as brushes can be attached to a part of the handle portion 300 by locking them in place, and locking holes for attaching other components may also be provided in a part of the handle portion 300.

[0034] Furthermore, as shown in Figures 1 and 4, the lid 400 is made entirely of synthetic resin and comprises a top plate 410 large enough to cover the opening 103 of the container body 100, and side plates 420 extending downward from the top plate 410. In addition, the inner surface of the side plates 420 is provided with projections 421 that protrude inward. Therefore, as shown in Figure 1, even when the inner container 200 is placed inside the container body 100, the projections 421 of the lid 400 can be locked onto a part of the upper end 121 of the side wall 120 of the container body 100 (for example, the flange portion 140), resulting in a good fit for the lid 400.

[0035] Furthermore, as shown in Figures 5 and 6, the inner container 200 is made entirely of synthetic resin and has a roughly rectangular parallelepiped shape. When the inner container 200 is placed in the container body 100, the inner container 200 occupies approximately half the size of the opening 103 of the container body 100. The inner container 200 comprises a bottom wall 210, an outer side wall 226 rising from the bottom wall 210, an inner side wall 227, side walls 228 on both sides, an opening 203 with an open top end, and an internal storage space 201. In addition, the outer surfaces of the side walls 228 on both sides of the inner container 200 are provided with inwardly recessed stepped portions 229.

[0036] The upper end 221 of the side wall of the inner container 200 is provided with a flat flange portion 240 and an outward-extending portion 241 extending downward from the flange portion 240. Furthermore, the upper end 221 of the inner side wall 227 is provided with a locking portion 250 projecting laterally from the outward-extending portion 241 below the flange portion 240. The flange portion 240 and the locking portion 250 form a stepped structure at the upper end 221 of the inner side wall 227. The flange portion 240 and the locking portion 250 also form an inner container mounting portion that rests on a part of the side wall 120 of the container body 100 when the inner container 200 is placed on the inside or outside of the side wall 120 of the container body 100, as will be described later. The outward-extending portion 241 of the flange portion 240 of the outer side wall 226 may be extended further downward to form a locking portion that can be locked to the upper end of the container body 100, etc.

[0037] Next, Figures 7 and 8 illustrate the assembled container 900 in which the inner container 200 is housed within the main container body 100. Figure 7(a) is a perspective view of the assembled container 900, Figure 7(b) is a plan view of the assembled container 900, Figure 8(a) is a view from end D to D, and Figure 8(b) is a view from end E to E.

[0038] As shown in Figures 7 and 8, the inner container 200 is housed in the storage space 101 through the opening 103 of the container body 100 and placed on the side wall 120 from the inside. Specifically, the flange portion 240, which is the inner container side mounting portion of the inner container 200, abuts against a part of the side wall 120 of the container body 100 (for example, the upper end side of the side wall 120), so that the inner container 200 is placed on a part of the side wall 120 so that it does not fall into the storage space 101 of the container body 100. In particular, since the flange portion 240, which is the inner container side mounting portion of the inner container 200, is mounted so as to engage with the container body side mounting portion 150 provided on the upper end side of the side wall 120 of the container body 100, the state in which the inner container 200 is placed on a part of the side wall 120 becomes more stable.

[0039] The container body mounting portion 150 is located on the upper end of the side wall 120, but is not limited to this. It may be located at any location below the upper end of the side wall 120, for example, at about half the height of the side wall 120, or at a location below half the height of the side wall 120. The container body 100 is provided with the container body mounting portion 150, but is not limited to this. The container body 100 does not need to provide the container body mounting portion 150. In that case, the flange portion 240, which is the inner container mounting portion of the inner container 200, is placed so as to engage with the flange portion 140 of the container body 100, or the flange portion 240 is placed so as to abut against any location on the inside of the side wall 120, thereby resting the inner container 200 on a part of the side wall 120.

[0040] Furthermore, when the inner container 200 is placed on the inside of the side wall 120 of the container body 100, one side wall 226 of the inner container 200 is configured to abut or be close to the inside of the side wall 120 of the container body 100, thus ensuring that the position and orientation of the inner container 200 are stable. Therefore, the inner container 200 can be stably maintained in a state where it is placed on a part of the side wall 120. Note that at least above and below the stepped portion 229, the side wall 226 of the inner container 200 and the side wall 120 of the container body 100 are in contact or close to each other.

[0041] The stepped portion 229 of the inner container 200 is positioned on the central side of the container body 100 and is also formed on the end or short side of the inner container 200. The stepped portion 229 is also formed on both the left and right sides of the inner container 200. Ribs may also be provided on the stepped portion 229. As shown in Figure 8, the depth D1 (horizontal length) of the stepped portion 229 is greater than the width D2 of the flange portion 240 of the inner container 200 (D1 > D2), so the inner container 200 can be stably placed on the side wall 120 of the container body 100. Furthermore, the depth D1 (horizontal length) of the stepped portion 229 is greater than the length D3 of the container body side mounting portion 150 (D1 > D3), so the inner container 200 can be stably placed on the side wall 120 of the container body 100.

[0042] Furthermore, as shown in Figures 5 and 6, the stepped portion 229 is provided with surfaces 208 and 209 that are substantially vertical. In plan view, surfaces 208 and 209 are connected to each other at substantially right angles. As shown in Figure 7(b), when the stepped portion 229 of the inner container 200 is placed on the protrusion 123 of the container body 100, the clearance (gap) between the surface 209 of the stepped portion 229 of the inner container 200 and the protrusion 123 of the container body 100 is larger than the clearance (gap) between the surface 208 and the protrusion 123. Also, the clearance (gap) between the inner container 200 and the container body 100 is smaller below the stepped portion 299 than above it. Furthermore, as shown in Figure 6, the height H1 of the stepped portion 229 is set to be 1 / 5 or more, or 1 / 3 or more, of the height H2 of the inner container 200 (H1 ≥ 1 / 5 × H2, or H1 ≥ 1 / 3 × H2).

[0043] Furthermore, by curving a portion of the bottom wall 210 of the inner container 200, it is easier to insert the inner container 200 between the side wall 120 and the protrusion 123 of the container body 100. Also, the degree of curvature (radius of curvature) of the bottom wall 210 of the inner container 200 is greater on the side facing the side wall 120 of the container body 100 than on the side facing the center of the container body 100, so that when the inner container 200 is inserted at an angle, it is less likely to get caught on the side wall 120 of the container body 100.

[0044] Furthermore, when the inner container 200 is housed inside the container body 100, the stepped portion 229 of the inner container 200 rests on the protrusion 123 of the container body 100. Therefore, the inner container 200 is more stable when it rests on a part of the side wall 120, preventing it from falling into the storage space 101 of the container body 100.

[0045] Furthermore, when the inner container 200 is housed inside the container body 100, the stepped portion 229 of the inner container 200 is positioned on the side of the center O of the container body 100. When the inner container 200 is housed inside the container body 100, the outside of the inner container 200 (i.e., the side with the side wall 226 that is away from the center O of the container body 100) is stably placed along the inside of the side wall 120 of the container body 100. On the other hand, the inside of the inner container 200 (i.e., the side with the other side wall 227 that is positioned on the side of the center O of the container body 100) is floating away from the side wall 120 of the container body 100, so there is a risk that the inner container 200 may tilt towards the center O due to unintentional external forces or the weight of the contents of the inner container 200. Therefore, by positioning the stepped portion 229 of the inner container 200 towards the center O side of the container body 100, the inside of the inner container 200 is supported, and the state in which the inner container 200 is resting on a part of the side wall 120 is made more stable so that it does not tilt.

[0046] As shown in Figure 7(b), in a plan view, the inner container 200 is housed on the right half side of the opening 103 of the container body 100. However, it is not limited to this, and the inner container 200 can be housed in any location regardless of the orientation of the inner container 200, such as on the left half side, upper half side, or lower half side of the container body 100. Furthermore, when the inner container 200 is housed on the upper half side or lower half side, the protrusions 123 may also be placed inside the left and right side walls 120 in a plan view.

[0047] Next, Figures 9 and 10 describe the assembled container 900 in which the inner container 200 is attached to the outside of the main container body 100. Figure 9(a) is a perspective view of the assembled container 900, Figure 9(b) is a plan view of the assembled container 900, and Figure 10 is an F-F end view.

[0048] As shown in Figures 9 and 10, the inner container 200 is placed on the side wall 120 from the outside. Specifically, the locking portion 250, which is the inner container side mounting portion of the inner container 200, locks to a part of the side wall 120 of the container body 100 (for example, the upper end of the side wall 120), so that it is placed on a part of the side wall 120 on the outside of the container body 100. In this way, since the inner container side mounting portion of the inner container 200 is placed on a part of the side wall 120 from both the inside and outside of the container body 100, the inner container 200 can be housed inside the container body 100 or attached to the outside of the container body 100. Therefore, the entire storage space 101 of the container body 100 can be effectively utilized.

[0049] Furthermore, since the locking portion 250, which is the inner container side mounting portion of the inner container 200, is mounted so as to lock into the container body side mounting portion 150 provided on the upper end side of the side wall 120 of the container body 100, the state in which the inner container 200 is mounted on a part of the side wall 120 becomes more stable. In this way, the container body side mounting portion 150 of the container body 100 allows a part of the inner container 200 (for example, the flange portion 240 shown in Figure 8 or the locking portion 250 shown in Figure 10) to be mounted on the side wall 120 of the container body 100 from both the inside and the outside, the state in which the inner container 200 is mounted on a part of the side wall 120 from both the inside and the outside becomes more stable.

[0050] Furthermore, when the inner container 200 is placed on the outside of the side wall 120 of the container body 100, the other side wall 227 of the inner container 200 is configured to abut or be close to and follow the outside of the side wall 120 of the container body 100, thus stabilizing the position and orientation of the inner container 200. Therefore, the inner container 200 can be stably maintained in a state where it is placed on a part of the side wall 120.

[0051] As shown in Figure 9(b), in a plan view, the inner container 200 is positioned to the right of the main container body 100. However, it is not limited to this, and the inner container 200 can be positioned to the left, above, or below the main container body 100, or at any other location regardless of the orientation of the inner container 200. Furthermore, if the inner container 200 is positioned above or below, it is preferable to remove the handle portion 300 so that the inner container 200 does not interfere with the handle portion 300. In addition, the inner container 200 does not need to have an inner container side mounting portion.

[0052] Next, Figure 11 shows the assembled container 900 with the inner container 200 housed in the container body 100, with the lid 400 engaged with the container body 100 by the handle portion 300. Figure 11(a) is a perspective view of the assembled container 900, Figure 11(b) is a plan view of the assembled container 900, and Figure 11(c) is an end view along G-G.

[0053] As shown in Figure 11, the inner container 200 is housed inside the container body 100, and with the lid 400 standing vertically, the projection 421 of the lid 400 is locked to a part of the upper end 121 of the side wall 120 of the container body 100 (for example, the flange portion 140). When the handle portion 300 is rotated to lie horizontally, the grip portion 310 of the handle portion 300 is positioned to wrap around to the outside of the lid 400. As a result, the projection 421 of the lid 400 is locked to a part of the upper end 121 of the side wall 120 of the container body 100 (for example, the flange portion 140), and the state in which the lid 400 is engaged with the container body 100 is firmly maintained. In this way, the lid 400 can be temporarily fixed to the container body 100, preventing it from falling off and being damaged by wind or impact. Furthermore, since the gripping portion 310 of the handle portion 300 is in contact with the recess 422 of the side plate 420 of the lid 400, the handle portion 300 is less likely to come off the lid 400, and the state in which the lid 400 is engaged with the container body 100 is maintained more strongly.

[0054] When the inner container 200 is housed inside the container body 100, the flange portion 240, which is the inner container side mounting portion of the inner container 200, rests on the container body side mounting portion 150 of the container body 100. Furthermore, the projection 421 of the lid 400, which is fixed by the handle portion 300, is located above the flange portion 240 of the inner container 200, thus preventing the inner container 200 from unintentionally lifting up and detaching from the container body 100.

[0055] Furthermore, the container assembly of the present invention is not limited to the above-described embodiments, and various modifications and combinations are possible within the scope of the claims and embodiments, and these modifications and combinations are also included within the scope of the patent rights.
