[Figure 5] This is an explanatory cutout perspective view showing the nesting state of this embodiment. [Modes for carrying out the invention]

[0015] An optimal embodiment of the present invention will be briefly described based on the drawings, illustrating the operation of the present invention.

[0016] The storage container of the present invention is composed of a box-shaped container A in which a side wall portion 2 is provided upright on the outer peripheral edge portion of a bottom portion 1, and a flange portion 3 protrudes outwardly at the upper portion of the side wall portion 2, and a card holder B that is attached to the outer surface of the side wall portion 2 of the box-shaped container A and detachably supports an information display card 4. Between the guide ridges 6 provided opposite to the outer surface of the side wall portion 2 of the box-shaped container A, when the card holder B is moved upward from below the box-shaped container A, each insertion portion 9 provided on both upper sides and both lower sides of the holder body 8 is inserted into the upper end portions of the respective opposed guide ridges 6 or two positions on the flange portion 3 where the upper end portions of the respective opposed guide ridges 6 face, and each insertion engagement portion 7 provided at the lower end portions of the respective opposed guide ridges 6 is inserted from below. At the same time, a locking portion 10 provided on at least one of the insertion portions 9 is locked against the insertion engagement portion 7 (the insertion state of the insertion portion 9 into the insertion engagement portion 7 is maintained), and the card holder B is held against removal from the guide ridges 6 and the flange portion 3 or is held against removal from the guide ridges 6 and attached to the outer surface of the side wall portion 2.

[0017] Therefore, troublesome attachment work such as welding the card holder B to the box-shaped container A is unnecessary, and the card holder B can be attached to the outer surface of the side wall portion 2 of the box-shaped container A by a simple operation of simply inserting the card holder B along the guide ridges 6 from below the box-shaped container A. Moreover, the attachment state is such that the respective insertion portions 9 on both upper sides and both lower sides of the holder body 8 are inserted and held (at least a four-point support state is maintained) in the respective insertion engagement portions 7 corresponding thereto. Therefore, even if the card holder B is pulled forward or bent, it will not come off from the side wall portion 2 of the box-shaped container A.

Embodiment

[0018] A specific embodiment of the present invention will be described based on the drawings.

[0019] This embodiment applies the present invention to a container of the same type as that described in Patent Document 1, and as shown in Figure 1, it consists of an upward-opening box-shaped container A made of synthetic resin (e.g., polypropylene) with a substantially rectangular plate-shaped bottom (bottom wall) 1, side walls 2 erected on the outer peripheral edge (four side edges), and flanges 3 that also function as handles protruding outward from the entire upper circumference of the side walls 2, and a card holder B made of synthetic resin (e.g., polypropylene) attached to the outer surface of the side walls 2 of the box-shaped container A, which detachably supports an information display card 4 on which information such as that of the items stored inside the box-shaped container A is displayed.

[0020] Furthermore, in this embodiment, the box-shaped container A has reinforcing vertical ribs 6 having vertical length and spacing in the horizontal direction, provided (integrally molded) on the outer surface of the side wall portion 2, and these opposing reinforcing ribs 6 are configured as guide protrusions 6, and the card holder B is arranged between these opposing guide protrusions 6 (see Figure 2). In other words, this embodiment is configured so that the card holder B is attached to the box-shaped container A using the reinforcing ribs 6 that are normally provided in this type of container (box-shaped container).

[0021] Furthermore, insertion engagement parts 7 for attaching the card holder B are provided at a total of four locations: two locations on the flange portion 3 where the upper ends of each of the opposing guide protrusions 6 are located, and at the lower ends of each of the opposing guide protrusions 6. Alternatively, the insertion engagement parts 7 may be provided on the upper part of each of the guide protrusions 6 instead of the flange portion 3.

[0022] Furthermore, the flange portion 3 comprises a top plate portion 13 extending substantially horizontally from the upper edge of each side wall portion 2 toward the outer circumference, and a hanging piece 14 that extends substantially vertically downward from the leading edge of the top plate portion 13, and the insertion engagement portion 7 is provided on the top plate portion 13 of the flange portion 3.

[0023] Specifically, upper insertion engagement parts 7A (square through holes 7A) are provided (integrally molded) in a vertically penetrating manner at two locations on the top plate portion 13 where the upper ends of the opposing guide protrusions 6 are located, and inner guide pieces 15 are provided (integrally molded) adjacent to the opposite inner side of each of these through holes 7A, so as to serve as guides for inserting the upper insertion parts 9A (described later) into each through hole 7A from below, hanging down from the top plate portion 13 and protruding from the outer surface of the side wall portion 2.

[0024] Furthermore, the lower ends of each of the opposing guide protrusions 6 are provided (integrally molded) with lower insertion engagement portions 7B, which serve as the insertion engagement portions 7. These lower insertion engagement portions 7B are formed by a hole shape that is open on the lower side of each guide protrusion 6, and also has a hook shape when viewed from the bottom, with a vertically elongated slit shape on the opposing inner side (a hole 7B in which the lower insertion portion 9B (hook-shaped protrusion 9B), described later, is inserted from below, thereby positioning the lower part of the holder body 8 so that it hardly moves in the front-to-back direction).

[0025] Furthermore, in this embodiment, while the outer surfaces of all side walls 2 of the box-shaped container A are provided with corresponding guide protrusions 6, the card holder B is not attached to all of these outer surfaces of the side walls 2, but is configured to be attached only to one of the opposing side walls 2A on the short side. That is, the insertion engagement portion 7 is provided only on the guide protrusion 6 on one side wall 2A and the flange portion 3 (top plate portion 13) adjacent to the guide protrusion 6, and the card holder B is configured to be attached only to the side wall 2A having this insertion engagement portion 7. It should be noted that the card holder B may be attached to both outer surfaces of the side walls 2A on the short side of the box-shaped container A, or to one or both outer surfaces of the side walls 2B on the long side, or to all of the outer surfaces of the side walls 2.

[0026] Furthermore, the box-shaped container A in this embodiment is configured to be stackable and nestable.

[0027] Specifically, the box-shaped container A has eight elongated legs 23 formed by continuous reinforcing ribs protruding outward (integrally molded) from both sides of the outer surface of each side wall 2A and both sides of the outer surface of each side wall 2B. By placing these multiple legs 23 on the top plate 13 of the flange 3 of another box-shaped container A, the box-shaped containers A can be stacked. In this embodiment, the guide protrusions 6 are shown as being composed of elongated reinforcing ribs 6 that form part of the legs 23.

[0028] Furthermore, on both sides of the inner surface of each side wall portion 2A and on both sides of the inner surface of each side wall portion 2B, there are a total of eight elongated leg insertion recesses 24 (integrally molded) that correspond to the position of the leg portions 23 and into which the leg portions 23 can be inserted from above. The box-shaped containers A can be nested by inserting the leg portions 23 of another box-shaped container A into each of these leg insertion recesses 24 from above. Moreover, when multiple box-shaped containers A are stacked with the positions of the side wall portions 2A to which the card holder B can be attached aligned, the positions of the leg portions 23 of the upper box-shaped container A and the positions of the leg insertion recesses 24 of the lower box-shaped container A do not align, and the leg portions 23 of the upper box-shaped container A When part 23 is placed on the flange portion 3 (top plate portion 13) of the lower box-shaped container A to create a stacking state, and when multiple box-shaped containers A are stacked with the positions of the side wall portions 2A to which the card holder B can be attached reversed by 180 degrees between the upper and lower layers (so that the side wall portions 2A to which the card holder B can be attached of the upper box-shaped container A and the side wall portions 2A to which the card holder B can be attached of the lower box-shaped container A are facing opposite directions), the positions of each leg portion 23 of the upper box-shaped container A and the positions of each leg recess 24 of the lower box-shaped container A coincide, and the legs 23 of the upper box-shaped container A are fitted into each leg recess 24 of the lower box-shaped container A to create a nesting state.

[0029] Furthermore, in this embodiment, the box-shaped container A has a receiving recess 12 (for accommodating the card holder B) that accommodates the card holder B attached to the side wall 2A of the upper box-shaped container A when nesting. This receiving recess 12 is provided (integrally molded) on the inner surface of the side wall 2A opposite to the side wall 2A to which the card holder B is attached. In other words, as shown in Figure 5, the box-shaped containers A can be nested without any problems even with the card holder B attached, as the card holder B can be accommodated in the receiving recess 12.

[0030] As shown in Figure 3, the card holder B of this embodiment has a rectangular plate-shaped holder body 8 that is positioned between the opposing guide protrusions 6 and can be mounted along the outer surface of the side wall portion 2A. A card support portion 5 is provided on the lower center of the holder body 8 to detachably support an information display card 4 on which information such as the contents of the items stored in the box-shaped container A is displayed. Furthermore, mounting portions 11 are provided on both sides of the holder body 8 to be mounted along the guide protrusions 6, and insertion portions 9 are provided at a total of four locations, on the upper and lower parts of each of these mounting portions 11, to be inserted into the insertion engagement portion 7 from below.

[0031] Specifically, a cut-out plate portion 17 is formed in the lower central part of the holder body 8, with a shape that appears to have been cut out through a U-shaped notch 16 that penetrates the holder body 8 in the front-to-back direction. This cut-out plate portion 17 is positioned slightly forward of the front part of the holder body 8 and stands upright. This cut-out plate portion 17 is configured as a clamping plate portion 17 that can sandwich and support the lower side of the information display card 4 between itself and the front part of the holder body 8. Furthermore, the upper part of this clamping plate portion 17 is formed in a shape that curves convexly toward the rear side of the holder body 8, and this upper curved portion 18 is configured as a card guide portion 18 for inserting the information display card 4 from above.

[0032] Furthermore, the clamping plate portion 17 has strip-shaped cut-out pieces 20 formed on the left and right sides below the guide portion 18, which appear to have been cut out through a U-shaped notch 19 that penetrates the clamping plate portion 17 in the front-to-back direction. These left and right cut-out pieces 20 are formed to be slightly displaced and erected towards the rear side of the holder body 8, and these cut-out pieces 20 are configured to clamp and support the lower left and right portions of the information display card 4 between themselves and the rear surface portion of the clamping plate portion 17.

[0033] The front portion of the holder body 8, the clamping plate portion 17, and the clamping piece 20 form the card support portion 5 that clamps and supports the information display card 4 (see Figure 2).

[0034] Furthermore, the left and right side edges of the holder body 8 are formed in a flat surface shape that can come into contact with the opposing inner surfaces of each guide projection 6, and these left and right side portions 11 constitute the mounting portions 11. When the holder body 8 (card holder B) is placed between opposing guide projections 6, the shape and size of the holder body 8 are set and configured such that the mounting portions 11 on both sides come into contact with or are in close proximity to the opposing inner surfaces of each guide projection 6.

[0035] Furthermore, the upper portions of both the left and right sides of the holder body 8, including the attached portion 11, are formed (integrally molded) as vertically elongated protrusions 21 having thickness in the front-to-back direction. These protrusions 21 are formed to protrude upward from other parts, and a short plate-shaped upper insertion portion 9A, which serves as the insertion portion 9, is formed (integrally molded) to protrude upward from the upper end of the protrusion 21. This upper insertion portion 9A is configured to be inserted into the upper insertion engagement portion (through hole) 7A. In other words, the upper insertion portion 9A is provided at the upper end of the protrusion 21, including the attached portion 11.

[0036] Furthermore, the left and right upper insertion portions 9A each have a locking claw 10 (locking portion 10) formed (integrally molded) on their opposing outer surfaces, which engages with the edge of the through hole 7A to prevent it from coming loose when the upper insertion portion 9A is inserted into the through hole 7A from below. The locking portion 10 may be provided on the lower insertion portion 9B, or on both the upper insertion portion 9A and the lower insertion portion 9B.

[0037] Reference numeral 22 in the figure indicates a card holder that is attached (integrally molded) to the opposing surfaces at the lower ends of the left and right protruding portions 21, and this card holder 22 However, the card support portion 5 supports the upper left and right portions of the information display card 4, which is supported at its lower end, so as to prevent deformation (forward tilting) of the information display card 4.

[0038] Furthermore, hook-shaped protruding pieces 9B are formed (integrally molded) on the lower part of each of the attached portions 11 on both sides, facing outward. These protruding pieces 9B on both sides constitute the lower insertion portion 9B of the insertion portion 9, and the lower insertion portion 9B is configured to be inserted into the lower insertion engagement portion 7B from below at the same time that the upper insertion portion 9A is inserted into the upper insertion engagement portion 7A from below.

[0039] Therefore, as shown in Figure 4, when the card holder B is inserted upward from below the box-shaped container A into the gaps between the guide protrusions 6 located on the outer surface of the side wall portion 2 of the box-shaped container A, the upper insertion portions 9A on both sides of the upper part of the holder body 8 are inserted into the upper insertion engagement portions 7A located at two locations on the flange portion 3, and the lower insertion portions 9B on both sides of the lower part of the holder body 8 are inserted from below into the respective lower insertion engagement portions 7B located at the lower ends of the guide protrusions 6, and furthermore, the locking claws 10 provided on each upper insertion portion 9A are inserted into the upper insertion engagement portions 7 ABy engaging with the edge of the hole, the lower insertion part 9B is prevented from coming out downwards, and the lower insertion engagement part 7B is also prevented from coming out downwards and forwards (outside the side wall part 2A). As a result, the holder body 8 (card holder B) is fixed in place by the insertion part 9 with four-point locking (four-point support), so that even if the card holder B is pulled forward or bent, it will not come off the box-shaped container A (outside the side wall part 2A) and will not wobble around, ensuring a secure attachment.

[0040] Furthermore, the present invention is not limited to this embodiment, and the specific configuration of each constituent element can be designed as appropriate. [Explanation of Symbols]
