[0009] [Embodiment 1] An embodiment of the present disclosure will be described in detail below. For ease of explanation, the following description defines the up-down direction, left-right direction, and front-rear direction as indicated by the arrows in each drawing. The left-right direction and front-rear direction may also be referred to as the "horizontal direction." The direction from the inside to the outside of the container 1 is defined as the "outward direction," and the direction from the outside to the inside of the container 1 is defined as the "inward direction." In the following description, the term "rectangular" is not limited to a strict rectangular shape, but includes shapes that can be visually recognized as a rectangle overall, even if the corners are curved. Parts having the same function may be designated by the same reference numerals, and their description may be omitted.

[0010] (Container overview) 1 and 2, the container 1 includes a bottom wall component 30 having a generally rectangular shape in plan view, a pair of first side walls 10, and a pair of second side walls 20. The container 1 is made of a resin such as polypropylene.

[0011] (Bottom wall component) The bottom wall forming portion 30 includes a substantially rectangular bottom surface 31, a pair of first base portions 310 extending upward from each side edge of the bottom surface 31, to which the pair of first side walls 10 are attached, and a pair of second base portions 320 to which the pair of second side walls 20 are attached. The shape of the upper sides of the pair of first base portions 310 corresponds to the shape of the lower sides of the pair of first side walls 10, and the shape of the upper sides of the pair of second base portions 320 corresponds to the shape of the lower sides of the pair of second side walls 20. Because the respective shapes correspond to each other, the first side walls 10 and the first base portions 310 form a substantially integrated side wall when assembled as described below. Furthermore, the second side walls 20 and the second base portions 320 form a substantially integrated side wall.

[0012] As shown in FIG. 2 , the bottom wall constituent portion 30 has a plurality of bearing recesses 33 and a plurality of long bearing recesses 33A provided at predetermined intervals. More specifically, the plurality of bearing recesses 33 and the plurality of long bearing recesses 33A are provided at predetermined intervals in the first base portion 310 and the second base portion 320, respectively. The long bearing recesses 33A are provided near each corner of the bottom wall constituent portion 30. In other words, it can be said that the long bearing recesses 33A are provided at both ends of the pair of second base portions 320. Furthermore, the bearing recess 33 is provided between both ends of the second base portion 320. When arranging the long bearing recesses 33A and the bearing recesses 33 as described above, both ends of the second base portion 320 are designed to be higher in the vertical direction than the distance between both ends of the second base portion 320. In other words, the vertical height between both ends of the second base portion 320 is lower than that between both ends of the second base portion 320. The locations and numbers of the bearing recesses 33 and the long bearing recesses 33A may be determined appropriately depending on the size of the container 1, the lengths of the first base portion 310 and the second base portion 320, etc. The second base portion 320 may be taller in the vertical direction than the first base portion 310. The long bearing recess 33A is designed to be longer in the vertical direction than the bearing recess 33. The bearing recess 33 provided in the first base portion 310 receives the shaft portion 23 of the first side wall 10, which will be described later. The bearing recess 33 provided in the second base portion 320 receives the short shaft portion 23A of the second side wall 20, which will be described later. The long bearing recess 33A receives the long shaft portion 23B, which will be described later.

[0013] The bottom wall forming portion 30 includes an extension wall 34 that extends upward from the outer edge of the side of the second base portion 320 to which the second side wall 20 is attached. The extension wall 34 forms a part of the second base portion 320.

[0014] More specifically, the extension wall 34 is provided in the range where the bearing recess 33 is provided in the second base portion 320. In other words, the extension wall 34 is not provided in the range where the long bearing recess 33A is provided. The range where the bearing recess 33 is provided in the second base portion 320 is the range that overlaps in the vertical direction with the information display unit 21 (see FIGS. 3 and 4) described below.

[0015] Therefore, when the second base portion 320 is viewed from the front or rear, the vertical height of the second base portion 320 with the extension wall 34 provided is designed to be one step lower than the vertical height of the second base portion 320 without the extension wall 34 provided.

[0016] It is not essential to make the vertical height of the second base portion 320 provided with the extension wall 34 one step lower than the vertical height of the second base portion 320 without the extension wall 34, and the vertical height may be designed to be the same as the vertical height of the second base portion 320 without the extension wall 34.

[0017] As in this embodiment, by lowering the vertical height of the second base portion 320 on which the extension wall 34 is provided by one step, the visible range of the information display area in the information display unit 21 described below can be expanded.

[0018] The bottom wall constituent portion 30 is provided with stacking recesses 35 at each corner portion on the upper side of the bottom wall constituent portion 30. The bottom wall constituent portion 30 also has stacking protrusions 36 that extend downward from the lower side of the bottom surface 31 and are received in the stacking recesses 35. When the containers 1 are stacked vertically (the lower container 1 is in a folded state, which will be described later), the stacking protrusions 36 of the upper container are received in the stacking recesses 35. The stacking recesses 35 may be provided only in the first base portion 310, or only in the second base portion 320, or may be provided so as to straddle the first base portion 310 and the second base portion 320.

[0019] The stacking protrusions 36 are received in the stacking recesses 35, thereby restricting horizontal movement of the stacked containers 1. Note that the containers 1 stacked on top of one another can be stacked in either a folded state or an assembled state of the containers 1, which will be described later. The stacking recesses 35 and the stacking protrusions 36 may be formed into any shape that allows stacking.

[0020] When the pair of first side walls 10 and the pair of second side walls 20 are in an upright state, each corner of the container 1 is also provided with a stacking recess 12 (see FIG. 1). Similar to the stacking recess 35 described above, the stacking recess 12 receives the stacking protrusion 36 of the upper container when the containers 1 are stacked vertically (the lower container 1 is in an assembled state, as described below). The stacking recess 12 may be provided only on the first side wall 10, or only on the second side wall 20, or may be provided so as to straddle both the first side wall 10 and the second side wall 20.

[0021] (First side wall) The first side wall 10 is provided with a locking mechanism 11. By operating the locking mechanism 11, it is possible to switch between a locked state and an unlocked state. When the locking mechanism 11 is switched from the locked state to the unlocked state, the engagement between the first side wall 10 and the second side wall 20 is released. Note that the locking mechanism 11 may be configured with a known structure, and its arrangement on the first side wall 10 is not limited, so a detailed description thereof will be omitted.

[0022] The first side wall 10 is integrally provided with a shaft portion 23 (see FIG. 4) configured to be rotatable relative to the bottom wall constituent portion 30 (first base portion 310). The shaft portion 23 has the same shape and structure as the short shaft portion 23A provided on the second side wall 20, and will be described in detail below. The first side wall 10 is attached to the bearing recess 33 of the bottom wall constituent portion 30 (first base portion 310) via the shaft portion 23 so as to be rotatable relative to the bearing recess 33.

[0023] (Second side wall) As shown in FIG. 3, the second side wall 20 includes an information display portion 21, a fixing portion 22, and a shaft portion 23 (a short shaft portion 23A and a long shaft portion 23B).

[0024] (Information display section) The information display unit 21 is configured so as to be usable as an information display area. More specifically, the information display unit 21 is partitioned into a pair of horizontal walls 211 and a pair of vertical walls 212, and the inner surfaces of the pair of horizontal walls 211 and the pair of vertical walls 212 are connected to the flat plate portion 210. The information display unit 21 is configured so that the area surrounded by the pair of horizontal walls 211, the pair of vertical walls 212, and the flat plate portion 210 can be used as the information display area. Note that the horizontal walls 211 only need to be provided on the lower side of the second side wall 20 in the up-down direction, and in this case, the pair of vertical walls 212 may not be provided.

[0025] The pair of horizontal walls 211 each extend in the left-right direction and have a width extending outward from the side surface (flat plate portion 210) of the second side wall 20. The pair of vertical walls 212 each extend in the up-down direction and have a width extending outward from the side surface (flat plate portion 210) of the second side wall 20.

[0026] Here, the positional relationship between the lower horizontal wall 211 of the pair of horizontal walls 211 and the extension wall 34 will be described with reference to Fig. 6. In Fig. 6, the bottom wall constituent part 30 (second base part 320) including the extension wall 34 is shown in a see-through state.

[0027] As shown in Figure 6, of the pair of side walls 211, the side wall 211 located below the second side wall 20 in the vertical direction is positioned in a position hidden by the extension wall 34 when the pair of second side walls 20 are attached to the bottom wall component 30 and the pair of second side walls 20 are in an upright state.

[0028] The position hidden by the extension wall 34 is a position that is not visible due to the extension wall 34 when the second side wall 20 is viewed from the front, that is, when viewed from the front or rear in the front-to-rear direction. In other words, of the pair of side walls 211, the lower side wall 211 is disposed at a position lower than the height of the upper end of the extension wall 34 in the up-down direction when the second side wall 20 is viewed from the front.

[0029] The information displayed on the information display unit 21 is, for example, various information such as the items stored in the container 1, the number of items, the destination of the container 1, and the location of the items / container 1. This information is displayed or stored on, for example, paper, a resin plate such as plastic, a sign, a card, a wireless tag (sometimes called an electronic tag, RFID tag, IC tag, non-contact tag, smart card, etc.), etc., and is locked to the information display unit 21 by being sandwiched between a locking member 40 (described later) and the flat plate portion 210. Various information may be locked (held) by the locking member 40 alone.

[0030] The information display unit 21 may be provided on at least one of the pair of second side walls 20. For example, the information display unit 21 may be provided only on the second side wall 20 attached to the front side of the container 1, and the information display unit 21 may not be provided on the second side wall 20 attached to the rear side of the container 1.

[0031] Furthermore, the horizontal (left-right) width of the information display area of ​​the information display unit 21 is not particularly limited. It can be changed as appropriate depending on the information displayed on the information display unit 21. Furthermore, the position of the information display area of ​​the information display unit 21 is not particularly limited. It may be located at a corner in the horizontal (left-right) direction (a corner of the container 1), or there may be multiple areas in the horizontal (left-right) direction.

[0032] (Fixed part) Returning to Fig. 3, the fixing portion 22 will be described. As shown in Fig. 3, of the pair of side walls 211 that make up the information display unit 21, the lower side wall 211 is provided with a fixing portion 22 that fixes a locking member 40 that locks information displayed in the information display area. Examples of the locking member 40 include a card holder and a wireless tag holder.

[0033] The locking member 40 and the fixing portion 22 may have any shape as long as they have corresponding locking structures and fixing structures. In the example shown in Fig. 3, protrusions are provided on both ends of the lower side of the locking member 40, and the protrusions are fixed to the fixing portion 22. The fixing portion 22 and the locking member 40 will be described in detail later.

[0034] As described above, of the pair of lateral walls 211, the lateral wall 211 located on the lower side is disposed at a position lower than the height of the upper end of the extension wall 34 in the up-down direction when the second side wall 20 is viewed from the front. In addition, the fixing portion 22 is also disposed at a position lower than the height of the upper end of the extension wall 34 in the up-down direction when the second side wall 20 is viewed from the front. In other words, the fixing portion 22 is disposed at a position hidden by the extension wall 34.

[0035] As a result, the fixing portion 22 is protected by the extension wall 34, and therefore, for example, when the containers 1 are transported while lined up adjacent to each other, even if the containers 1 collide with each other, the fixing portion 22 is protected by the extension wall 34. Therefore, it is possible to prevent the locking member 40 fixed to the fixing portion 22 from peeling off or being damaged. Furthermore, information (paper, resin plate such as plastic, sign, card, wireless tag, etc.) that is sandwiched between the locking member 40 and the flat plate portion 210 and displayed on the information display unit 21 is prevented from falling off.

[0036] The extension wall 34 is not an essential component, and the second base portion 320 does not necessarily have to include the extension wall 34.

[0037] (shaft) The second side wall 20 is integrally provided with a short shaft portion 23A and a long shaft portion 23B that are configured to be rotatable relative to the bottom wall constituent portion 30 (second base portion 320). The short shaft portion 23A and the long shaft portion 23B are examples of the "shaft portion" in this disclosure. In the following description, when the term "shaft portion 23" is used, it is intended to include both the short shaft portion 23A and the long shaft portion 23B.

[0038] 3, the shafts 23 extend downward from the underside of the second side wall 20 and are spaced apart at predetermined intervals in the left-right direction. The shafts 23 of the first side wall 10 have the same structure as the shafts 23 of the second side wall 20, and extend downward from the underside of the first side wall 10 and are spaced apart at predetermined intervals in the left-right direction.

[0039] Short shaft portion 23A is designed to have a shorter shaft length extending downward than long shaft portion 23B in order to increase the vertical (particularly downward) length of information display portion 21. Short shaft portion 23A has shaft portion inclined surface 23Aa, which is a curved surface formed with a predetermined curvature. Long shaft portion 23B has shaft portion inclined surface 23Ba, which is a curved surface formed with a predetermined curvature.

[0040] The shaft inclined surface 23Aa serves to smooth the sliding movement between the shaft inclined surface 23Aa and the opposing surface in the bearing recess 33. The shaft inclined surface 23Ba serves to smooth the sliding movement between the shaft inclined surface 23Ba and the opposing surface in the long bearing recess 33A. Note that the shaft inclined surface 23Aa and the shaft inclined surface 23Ba are not limited to curved inclined surfaces, and the inclined surfaces may be formed in a polygonal shape so as to have a substantially curved shape.

[0041] The arrangement location and number of the shaft portions 23 may be set appropriately depending on the left-right length, size, etc. of the second side wall 20. The second side wall 20 is rotatably attached to the bearing recess 33 and the long bearing recess 33A of the bottom wall constituent part 30 (second base part 320) via the short shaft portion 23A and the long shaft portion 23B (shaft portion 23). The shaft portion 23 is similarly provided on the first side wall 10.

[0042] It should be noted that the long shaft portion 23B is not an essential component of the shaft portion 23 provided on the first side wall 10. That is, the shaft portion 23 provided on the first side wall 10 may be only the short shaft portion 23A. Similarly, the long shaft portion 23B is not an essential component of the second side wall 20. That is, the shaft portion 23 provided on the second side wall 20 may be only the short shaft portion 23A.

[0043] As shown in Figure 6, at least one of the shaft portions 23 provided on the second side wall 20 is positioned at a position where a virtual line Y perpendicular to the rotation axis direction X of the shaft portion 23 overlaps with the information display unit 21 in the vertical direction.

[0044] In this embodiment, the shafts 23 arranged at positions where an imaginary line Y perpendicular to the rotation axis direction X of the shafts 23 overlaps in the up-down direction with the information display unit 21 are three short shafts 23A. Note that the number of short shafts 23A is not limited to three, but may be one or four, and the number of short shafts 23A may be set appropriately depending on the length and size of the second side wall 20 in the left-right direction, etc.

[0045] By using short shaft portion 23A as shaft portion 23, which is disposed at a position where virtual line Y perpendicular to rotation axis direction X of shaft portion 23 overlaps with information display unit 21 in the vertical direction, it is possible to increase the vertical length of information display unit 21. In other words, it is possible to widen the information display area of ​​information display unit 21.

[0046] In order to widen the information display area of ​​the information display unit 21, it is preferable that the long shaft portion 23B is arranged with the information display unit 21 sandwiched therebetween, and it is preferable that the short shaft portion 23A is arranged between the long shaft portion 23B on the right end and the long shaft portion 23B on the left end, as shown in Figure 3.

[0047] (Assembly and folding of the container) As described above, the first side wall 10 and the second side wall 20 are rotatably attached to the bottom wall forming part 30 via the shaft part 23. This allows the container 1 to change state from an assembled state in which the pair of first side walls 10 and the pair of second side walls 20 are erected as shown in Fig. 1 to a folded state in which the pair of first side walls 10 and the pair of second side walls 20 are folded inward as shown in Fig. 4.

[0048] In the assembled state, the lower sides of the pair of second side walls 20 rest on the second base portion 320, and the short shaft portion 23A is received in the bearing recess 33 provided in the second base portion 320 (see FIG. 8).

[0049] In this embodiment, the locking mechanism 11 provided on the first side wall 10 is operated to switch from a locked state to an unlocked state, and then the pair of first side walls 10 are folded inward, and then the pair of second side walls 20 are folded inward to achieve the folded state. In other words, the pair of first side walls 10 are the side walls that are folded first, and the pair of second side walls 20 are the side walls that are folded last.

[0050] When folding the pair of second side walls 20 inward, the long shaft portion 23B is guided along the vertical direction of the long bearing recess 33A, and the pair of second side walls 20 are folded while sliding in the vertical direction by the vertical length of the long bearing recess 33A.

[0051] In the process of folding the pair of sliding second side walls 20 inward, the shaft inclined surfaces 23Aa and 23Ba slide on the inner surfaces of the bearing recess 33 and the long bearing recess 33A, thereby smoothly folding the pair of second side walls 20. In other words, the information display unit 21 can smoothly transition to the folded state while ensuring a large space for the information display area.

[0052] When the pair of second side walls 20 are folded as shown in Fig. 4, the short shaft portion 23A provided on the second side wall 20 is disengaged from the bearing recess 33 (is positioned above the bearing recess 33) as shown in Fig. 5. If the short shaft portion 23A is not disengaged from the bearing recess 33 when the pair of second side walls 20 are folded, the vertical height of the bearing recess 33 needs to be designed to be large.

[0053] In this case, since the lower sides of the pair of second side walls 20 rest on the second base portion 320 in the assembled state, the lower lateral wall 211 must be moved to an upper position by the amount corresponding to the increase in the vertical height of the bearing recess 33. If the lower lateral wall 211 is moved to an upper position, the vertical length of the information display unit 21 will be shortened (the lower end of the information display unit 21 must be cut out by the amount corresponding to the increase in the vertical height of the bearing recess 33, and the lower lateral wall 211 must be installed at a position corresponding to the height of the second base portion 320). In other words, compared to when the short shaft portion 23A is not separated from the bearing recess 33, the vertical height of the bearing recess 33 can be reduced, and the vertical length (particularly the downward direction) of the information display unit 21 can be increased, thereby widening the information display area.

[0054] Furthermore, since the short shaft portion 23A is detached from the bearing recess 33, even if the second side wall 20 is folded after the first side wall 10 is folded, the vertical height of the container 1 in the folded state (the height of the second base portion 320) can be prevented from increasing, and therefore, when the second side wall 20 is in an upright state, the information display area of ​​the information display portion 21 can be made wider in the vertical direction (especially downward).

[0055] When the second side wall 20 is folded as described above, the short shaft portion 23A is disengaged from the bearing recess 33. However, as shown in FIG. 5, the lower end of the short shaft portion 23A in the disengaged state faces the extended wall 34 in the front-to-rear direction. Because the lower end of the short shaft portion 23A faces the extended wall 34, the short shaft portion 23A can be protected even when disengaged from the bearing recess 33. This prevents damage due to external contact, etc. Furthermore, the outward movement of the second side wall 20 can be restricted. In other words, the second side wall 20 can be prevented from falling outward.

[0056] The second side wall 20 may have a convex protrusion in place of the long shaft portion 23B at a position corresponding to the long shaft portion 23B, and the second base portion 320 may have a concave recess in place of the long bearing recess 33A at a position corresponding to the long bearing recess 33A. In this case, the second side wall 20 may be rotatably attached to the second base portion 320 via the short shaft portion 23A. Furthermore, when the second side wall is assembled, the convex protrusion and the concave recess may be configured to fit together.

[0057] The order in which the first side walls 10 and the second side walls 20 are folded is not limited to the above order, and the pair of second side walls 20 may be folded inward first, and then the pair of first side walls 10 may be folded inward.

[0058] As described above, the container 1 is configured to be movable between a folded state and an assembled state, and has the following features: In other words, the container 1 is configured such that, when the pair of first side walls 10 is in a folded state and the pair of second side walls 20 is in an upright state, the lower ends of the shafts 23 of the pair of second side walls 20 are positioned below the outer surface T of the first side walls 10.

[0059] Furthermore, when the pair of first side walls 10 are in a folded state and the pair of second side walls 20 are in an upright state, the lower ends of the bearing recess 33 and the long bearing recess 33A corresponding to the short shaft portion 23A are configured to be positioned below the outer surface T of the first side wall 10.

[0060] 3, the lower ends of short shaft portion 23A and long shaft portion 23B are aligned at the same height in the vertical direction. It is not essential that the lower ends of short shaft portion 23A and long shaft portion 23B be aligned at the same height in the vertical direction, and this may be set appropriately depending on the design of shaft portion 23, etc.

[0061] The above features will be explained using Figures 7 and 8. Figure 7 shows the container 1 in which the pair of first side walls 10 is folded and the pair of second side walls 20 is standing. As shown in Figure 7, the pair of first side walls 10 is folded with the outer surface T facing upward.

[0062] 7, the pair of first side walls 10 are designed so that, when folded, their length in the left-right direction does not reach the center of the container 1 (the center of the bottom surface 31). In other words, when the pair of first side walls 10 are folded, the bottom surface 31 of the container 1 is visible.

[0063] The present disclosure is an invention that is particularly effective when there is a limit to the size of the container 1, such as when the first side wall 10 has a short vertical height and the second side wall 20 is designed to have a short vertical height to match the vertical height of the first side wall 10. This is because when there is a limit to the size of the container 1, the space that can be used as the information display area of ​​the information display unit 21 is limited.

[0064] However, since the purpose of the present disclosure is to realize a container 1 that has a wider area that can be used as an information display area than conventional containers, the length of the pair of first side walls 10 is not limited to the above.

[0065] For example, the pair of first side walls 10 may be designed so that the length in the left-right direction reaches the center of the bottom surface 31 when folded, or so that the pair of first side walls 10 overlap in the up-down direction. In other words, the length of the pair of first side walls 10 may be set appropriately depending on the size, design, etc. of the container 1.

[0066] 8, the container 1 is configured such that, when the pair of first side walls 10 is in a folded state and the pair of second side walls 20 is in an upright state, the lower ends of the shaft portions 23 provided on the pair of second side walls 20 are positioned below the outer surface T of the first side walls 10. More specifically, the container 1 is configured such that the lower ends of all of the long shaft portions 23B and the short shaft portions 23A are positioned below the outer surface T of the first side walls 10.

[0067] It is not essential that the lower ends of all of the long shaft portion 23B and the short shaft portion 23A are configured to be located below the outer surface T of the first side wall 10. For example, it is sufficient that at least one of the long shaft portion 23B and the short shaft portion 23A is configured to be located below the outer surface T of the first side wall 10.

[0068] (Details of the fixing part) The fixing portions 22 will now be described in detail with reference to Fig. 9. As shown in Fig. 9, of the pair of lateral walls 211 included in the second side wall 20, the lateral wall 211 provided on the lower side includes a pair of fixing portions 22.

[0069] (First Restriction Wall) The fixing portion 22 includes a first restricting wall 221 extending in the lateral direction (left-right direction) along the lateral wall 211 and upward from the lateral wall 211. The first restricting wall 221 is a wall that restricts movement of the locking member 40 rearward in the front-rear direction when the locking member 40 is inserted into the fixing portion 22.

[0070] (Second regulatory wall) The fixing portion 22 also includes a second restricting wall 222 extending outward (forward in the front-rear direction) from one of both ends of the first restricting wall 221 in the left-right direction, in a direction perpendicular to the extending direction of the first restricting wall 221. The second restricting wall 222 is a wall that restricts movement of the locking member 40 in the left-right direction when the locking member 40 is inserted into the fixing portion 22.

[0071] Note that "one of both ends" in the left-right direction of the first restricting wall 221 refers to the left end in the case of the left-side fixing portion 22 of the pair of fixing portions 22 provided on the horizontal wall 211, and refers to the right end in the case of the right-side fixing portion 22. Therefore, the inner surfaces of the second restricting walls 222 are arranged in positions facing each other.

[0072] The positions at which the second restriction walls 222 are provided are not limited to the right and left ends described above, and they may be provided in the center, or the right and left ends may be reversed. Also, the second restriction wall 222 may not be provided, and the fixing portion 22 may be configured by the first restriction wall 221 and the third restriction wall 223.

[0073] In this case, movement of the locking member 40 in the left-right direction is restricted by the opposing end faces of the pair of third restriction walls 223. In other words, the left-right side faces of the locking member 40 inserted into the fixing portion 22 come into contact with or come close to the third restriction walls 223, so that movement of the locking member 40 in the left-right direction can be restricted.

[0074] (Third regulatory wall) Furthermore, the fixing portion 22 includes a third restriction wall 223 that connects the upper sides of the first restriction wall 221 and the second restriction wall 222. The third restriction wall 223 is a wall that restricts the upward movement of the locking member 40 in the up-down direction when the locking member 40 is inserted into the fixing portion 22.

[0075] In addition, in FIG. 9, the third restriction wall 223 is formed so that its length in the left-right direction and the front-rear direction is the same as that of the first restriction wall 221 and the second restriction wall 222, but this is not limited to this.

[0076] For example, the length of the third restriction wall 223 in the left-right direction may be longer or shorter than the overall length of the first restriction wall 221. Furthermore, the length of the third restriction wall 223 in the front-rear direction may be shorter than the overall length of the second restriction wall 222 in the front-rear direction.

[0077] In other words, the size and shape of the third restricting wall 223 may be set appropriately as long as it can restrict upward movement of the locking member 40 in the up-down direction when the locking member 40 is inserted into the fixing portion 22.

[0078] The fixing portion 22 configured as described above is disposed so as to be located outside (forward) the information display portion 21 at a predetermined distance. Specifically, as shown in FIG. 11 , a space (gap) is formed between the side surface of the information display portion 21 and the first restriction wall 221. More specifically, the first restriction wall 221, the second restriction wall 222, and the third restriction wall 223 are provided outside (forward) the information display portion 21 at a predetermined distance. More specifically, the base bottom 411 (see FIG. 10 ), the insertion portion 412, and the lower end side of the base portion 41 are disposed outside (forward) the information display portion 21 at a predetermined distance. In other words, a space (gap) is formed between the side surface of the information display portion 21 and the fixing portion 22, the base bottom 411, and the lower end side of the base portion 41.

[0079] For example, consider the case where a card bearing the name of an item to be stored in container 1 is inserted from above. In this case, a space (gap) is formed between the side surface of information display unit 21 and first restriction wall 221, so that the bottom end of the inserted card can be inserted up to the top surface of side wall 211 without being obstructed by fixing unit 22.

[0080] More specifically, a space (gap) is formed between the side of the constant information section 21 and the first restricting wall 221, the second restricting wall 222, the third restricting wall 223, the base bottom 411, the insertion section 412, and the lower end side of the base section 41, so that the lower end of the inserted card can be inserted up to the upper surface of the side wall 211 without being obstructed by the above-mentioned parts of the locking member 40. Therefore, the information to be displayed on the information display section 21 can be kept locked by the locking member 40, and the display area for the information to be displayed on the information display section 21 can be used to the maximum extent possible.

[0081] The fixing portion 22 may be provided on the upper horizontal wall 211 of the pair of horizontal walls 211. Alternatively, the fixing portion 22 may be provided on either one of the pair of vertical walls 212 or on both of the pair of vertical walls 212. In this case, the display area for information displayed on the information display unit 21 can be effectively utilized upward or to the left and right. Alternatively, for example, the fixing portion 22 may be provided on the horizontal wall 211 and the vertical wall 212, and the locking member 40 may be fixed by these multiple fixing portions 22.

[0082] (Lock recess) 9, of the pair of lateral walls 211 provided on the second side wall 20, the lateral wall 211 provided on the lower side has a pair of locking recesses 213. The locking recesses 213 are configured to be able to lock locking protrusions 414 described below. The positions, sizes, and number of the locking recesses 213 may be set appropriately in accordance with the positions, sizes, and number of the locking protrusions 414.

[0083] (Details of the locking member) 10 is a diagram showing locking member 40, with the upper side of Fig. 10 being a diagram of locking member 40 viewed from the front, and the lower side of Fig. 10 being a diagram of locking member 40 viewed from the rear. As shown in Fig. 10, locking member 40 includes a base portion 41, a base bottom portion 411, an insertion portion 412, a guide portion 413, and a locking protrusion 414.

[0084] The locking member 40 is made of a resin such as polypropylene. The base portion 41 is made of a thin plate that is generally rectangular in plan view. The size and area of ​​the base portion 41 may be set appropriately according to the size and area of ​​the information display unit 21. In this embodiment, the base portion 41 is molded into a rectangle.

[0085] When the locking member 40 is fixed to the fixed portion 22, the base portion 41 serves to press and hold a card or the like, on which information or the like is written, inserted between the base portion 41 and the information display portion 21, toward the information display portion 21. Therefore, it is sufficient that the locking member 40 is fixed to the fixed portion 22 so that at least a portion of the base portion 41 abuts against the information display portion 21.

[0086] The base portion 41 has a base bottom portion 411 extending forward from the lower edge of the base portion 41. The base bottom portion 411 is the portion that abuts against the lateral wall 211 when the locking member 40 is inserted into the fixing portion 22, and is designed to be wider in the front-to-rear direction by approximately the same length as the length in the front-to-rear direction of the second restricting wall 222. With this design, the base bottom portion 411 functions as an installation surface to be installed on the lateral wall 211.

[0087] The base bottom 411 has a pair of insertion portions 412 extending rightward from the right end of the base bottom 411 and leftward from the left end of the base bottom 411. The insertion portions 412 are portions that are inserted into the fixed portion 22, and the locking member 40 is fixed to the fixed portion 22 by inserting the insertion portions 412 into the fixed portion 22.

[0088] After the insertion portion 412 is inserted into the fixing portion 22, the insertion portion 412 may be fixed with an adhesive such as an adhesive so as not to come off the fixing portion 22. In this embodiment, the locking member 40 is configured to be detachable from the fixing portion 22. Furthermore, the insertion portion 412 is an example of a portion to be fixed, and since the fixing portion 22 can be formed into various shapes as described above, the insertion portion 412 may be formed to match the shape of the fixing portion 22.

[0089] The base portion 41 includes a guide portion 413 that extends upward from the upper edge of the base portion 41 and is inclined outward (forward) with respect to the front surface of the base portion 41. By providing the guide portion 413, when the locking member 40 is inserted into and fixed to the fixing portion 22, a gap equal to the inclination angle of the guide portion 413 is formed between the information display unit 21 and the upper side of the locking member 40.

[0090] By forming such a gap, for example, when inserting a card bearing the name of an item to be stored in container 1 from above, it becomes easier to insert the card between locking member 40 and information display unit 21 while being guided by guide portion 413.

[0091] Furthermore, because guide portion 413 is inclined outward with respect to the front surface of base portion 41, it also functions as a handle when attaching or detaching locking member 40 to or from fixed portion 22. In other words, the user can insert his or her finger into the gap to attach or detach locking member 40.

[0092] 10, the base bottom 411 has a pair of locking protrusions 414 extending downward from the lower surface of the base bottom 411. The locking protrusions 414 are designed to have a shape that allows them to be inserted into the locking recesses 213. In this embodiment, the side cross section along the front-to-rear direction is shaped into a substantially triangular shape that tapers toward the rear.

[0093] That is, the lower surface of the locking protrusion 414 (the surface facing the side wall 211) is inclined from the front to the rear so as to gradually approach the base bottom 411. By shaping the locking protrusion 414 in this manner, the locking protrusion 414 also functions as a guide surface when the locking member 40 is inserted into the fixing part 22.

[0094] Furthermore, when the locking protrusion 414 is locked in the locking recess 213, the front surface of the locking protrusion 414 catches in the locking recess 213, making it difficult for the locking member 40 to come off the fixed part 22. The relationship between the locking protrusion 414 and the locking recess 213 may be reversed. That is, the locking protrusion 414 may be a recess, and the locking recess 213 may be a convex part. The locking recess 213 is not limited to a depression with a bottom, but may also be a through-hole that runs through without a bottom. In this embodiment, the amount of protrusion of the locking protrusion 414 from the lower surface of the base bottom 411 is molded to be within the thickness of the lower side wall 211 when the locking member 40 is fixed to the fixed part 22. As a result, even if the locking recess 213 is configured as a through-hole, the locking protrusion 414 fits within the thickness of the side wall 211 and does not protrude below the lower surface of the lower side wall 211.

[0095] (Action and effect) As described above, according to this embodiment, the following advantageous effects can be obtained.

[0096] The container 1 according to aspect 1 of the present disclosure is a container 1 comprising a bottom wall component 30 having a substantially rectangular bottom surface 31 and base portions (first base portion 310, second base portion 320) extending upward from each side edge of the bottom surface 31, and a pair of first side walls 10 and a pair of second side walls 20 rotatably attached to the bottom wall component 30, wherein at least one of the pair of second side walls 20 comprises an information display portion 21 that can be used as an information display area, and a horizontal wall 211 below the second side wall 20 in the vertical direction, and the horizontal wall 211 comprises a fixing portion 22 that fixes a locking member 40 that locks information displayed in the information display area, and the fixing portion 22 is arranged outside the information display portion 21 at a predetermined distance.

[0097] According to the above configuration, the fixed portion 22 is disposed so as to be positioned outward from the information display portion 21 at a predetermined distance. This leaves a space (gap) between the side surface of the information display portion 21 and the fixed portion 22. When an information display area is provided, as in the container 1 of the present disclosure, a card or the like bearing, for example, the names and number of items stored in the container 1 is generally inserted and displayed in the information display area. When a space (gap) is formed between the side surface of the information display portion 21 and the fixed portion 22, as in the container 1 of the present disclosure, the bottom end of a card inserted into the information display area 21 can be inserted all the way to the bottom of the information display portion 21 without being obstructed by the fixed portion 22. Therefore, a container can be realized that allows for more effective use of the display area for information displayed on the information display portion 21 than conventional containers.

[0098] A container 1 according to aspect 2 of the present disclosure may be configured such that, in the above-mentioned aspect 1, the fixing portion 22 includes a first restricting wall 221 extending upward from the side wall 211, the locking member 40 includes a fixed portion (insertion portion 412) fixed to the fixing portion 22, and when the fixed portion (insertion portion 412) is fixed to the fixing portion and the locking member is attached to the container, the fixed portion (insertion portion 412) is located outward of the first restricting wall 221 and faces the first restricting wall 221 horizontally.

[0099] According to the above configuration, the fixing portion 22 is provided with a first restricting wall 221 extending upward from the side wall 211, so that stable fixing is possible even if a base portion (second base portion 320) is located directly below the side wall 211.

[0100] In the container 1 according to the third aspect of the present disclosure, in the first aspect, the second side wall 20 provided with the information display unit 21 is configured with shafts 23 (short shafts 23A and long shafts 23B) that are rotatable relative to the bottom wall component 30, and the shafts 23 extend downward from the underside of the second side wall 20, and are arranged at a position where a virtual line Y perpendicular to a rotation axis direction X of at least one of the shafts 23 overlaps with the information display unit 21 in the up-down direction. 3, and the container 1 can be changed from an assembled state in which the pair of first side walls 10 and the pair of second side walls 20 are erected to a folded state in which the pair of first side walls 10 and the pair of second side walls 20 are folded inward, and when the pair of first side walls 10 are in the folded state and the pair of second side walls 20 are in the erected state, the lower end of the shaft portion 23 may be located below the outer surface of the first side wall 10.

[0101] According to the above configuration, the container 1 includes at least one shaft portion 23 that is arranged at a position where an imaginary line Y that is perpendicular to the rotation axis direction X of the shaft portion 23 overlaps in the vertical direction with the information display unit 21. Furthermore, when the pair of first side walls 10 are in a folded state and the pair of second side walls 20 are in an upright state, the lower ends of the shaft portions 23 included in the pair of second side walls 20 are positioned below the outer surfaces of the first side walls 10.

[0102] Generally, in the case of a container 1 having a structure in which a pair of first side walls 10 and a pair of second side walls 20 are folded as in the present disclosure, the lower end of the shaft portion 23 is designed to be positioned above the outer surface T of the first side wall 10. This is because if the lower end of the shaft portion 23 is positioned below the outer surface T of the first side wall 10, there is a problem in that the shaft portion 23 gets in the way when folding.

[0103] However, the container 1 of the present disclosure solves the above-mentioned problem while being configured such that the lower end of the stem 23 is positioned below the outer surface T of the first side wall 10. This allows the position of the stem 23 in the up-down direction to be lower than in the past, thereby realizing a container 1 with a wider area available as an information display area than in the past.

[0104] The container 1 according to aspect 4 of the present disclosure may be configured such that, in the above-mentioned aspects 1 or 2, the bottom wall component 30 further includes an extension wall 34 extending upward from the outer edge of the side of the bottom wall component 30 to which the pair of second side walls 20 are attached.

[0105] According to the above configuration, the extension wall 34 extends upward from the outer edge of the side to which the pair of second side walls 20 are attached. As a result, when the pair of second side walls 20 are folded, the shaft 23, which is positioned so that an imaginary line Y perpendicular to the rotation axis direction X of at least one of the shafts 23 overlaps with the information display unit 21 in the up-down direction, can be restricted to move inward in the inward-outward direction.

[0106] [Embodiment 2] A container 1-1 according to a second embodiment of the present disclosure will be described in detail below with reference to FIGS. 12 to 17. For ease of explanation, the vertical, horizontal, and front-to-rear directions are defined as indicated by the arrows in the drawings. The horizontal and front-to-rear directions may also be referred to as the "horizontal direction." The direction from the inside to the outside of the container 1-1 is defined as the "outward direction," and the direction from the outside to the inside of the container 1-1 is defined as the "inward direction." In the following description, the term "rectangular" is not limited to a strict rectangular shape, but includes shapes that can be visually recognized as a rectangle overall, even if the corners are curved. Parts having the same function may be designated by the same reference numerals, and their description may be omitted.

[0107] (Container overview) 12 and 13, the container 1-1 includes a bottom wall component 30-1 having a generally rectangular shape in plan view, a pair of first side walls 10-1, and a pair of second side walls 20-1. The container 1 is made of resin such as polypropylene.

[0108] (Bottom wall component) The bottom wall constituent part 30-1 includes a substantially rectangular bottom surface 31-1, a pair of first base parts 310-1 extending upward from each side edge of the bottom surface 31-1 and to which the pair of first side walls 10-1 are attached, and a pair of second base parts 320-1 to which the pair of second side walls 20-1 are attached. The pair of first base parts 310-1 and the pair of second base parts 320-1 are collectively referred to as base parts 32-1 extending upward from each side edge of the bottom surface 31-1 of the bottom wall constituent part 30-1.

[0109] As shown in Fig. 13, the bottom wall component 30-1 has a plurality of bearing recesses 33-1 provided at predetermined intervals in each first base portion 310-1. Each bearing recess 33-1 extends in the vertical direction from a position flush with the bottom surface 31-1 to the upper end surface of the first base portion 310-1. The placement locations and number of bearing recesses 33-1 may be determined appropriately depending on the size of the container 1-1, the length of the first base portion 310-1, etc. The bearing recesses 33-1 receive the shaft portion 10A-1 (see Fig. 12) of the first side wall 10-1.

[0110] Each second base portion 320-1 of the bottom wall component 30-1 is formed with a U-shaped cross section that opens downward (see FIG. 17), the upper end surface of the second base portion 320-1 is formed as a substantially horizontal surface, and a pair of wide bearing recesses 33A-1 is provided at both longitudinal ends of each second base portion 320-1. The wide bearing recesses 33A-1 are provided so as to extend a predetermined height upward in the vertical direction from a position at the same height as the upper end surface of the second base portion 320-1.

[0111] Furthermore, the upper end surface of the second base portion 320-1 is slightly higher in the vertical direction than the upper end surface of the first base portion 310-1 (bearing recess 33-1 thereof). The upper end surface of the second base portion 320-1 may be at the same height as the upper end surface of the first base portion 310-1 (bearing recess 33-1 thereof). The upper end surface of the wide bearing recess 33A-1 is higher in the vertical direction than the upper end surface of the first base portion 310-1 (bearing recess 33-1 thereof).

[0112] The height from the upper end surface of the second base portion 320-1 to the upper end of the wide bearing recess 33A-1 is preferably approximately the same as the width dimension in the front-to-rear direction of the upper end surface of the second base portion 320-1. The wide bearing recess 33A-1 is designed to be longer in the left-to-right direction than the bearing recess 33-1. The wide bearing recess 33A-1 receives the shaft portion 23-1 (see FIG. 14) of the second side wall 20-1, which will be described later.

[0113] Additionally, the upper end surface of each second base portion 320-1 is provided with a plurality of locking holes 34-1 penetrating vertically at predetermined intervals between the wide bearing recesses 33A-1 provided at both ends. Each locking hole 34-1 is formed in a rectangular shape in a plan view that is elongated in the left-right direction. Each locking hole 34-1 is provided with a first locking stopper 34A-1 that is rectangular in a plan view and protrudes a predetermined height from the center of the outer side edge of the locking hole 34-1 to the outer edge of the second base portion 320-1. Each locking hole 34-1 is provided with a second locking stopper 34B-1 that is square in a plan view and protrudes a predetermined height from the center of the inner side edge of the locking hole 34-1 to the inner edge of the second base portion 320-1. The location and number of the locking holes 34-1 may be determined appropriately depending on the size of the container 1-1, the length of the second base portion 320-1, etc. When the container 1-1 is in an assembled state, a locking projection 25-1 (see FIG. 14) of the second side wall 20-1, which will be described later, fits into the locking hole 34-1.

[0114] (First side wall) As shown in Figure 12, the first side wall 10-1 is provided with a locking mechanism 11-1. By operating the locking mechanism 11-1, it is possible to switch between a locked state and an unlocked state. When switched from the locked state to the unlocked state, the engagement between the first side wall 10-1 and the second side wall 20-1 is released. Note that the locking mechanism 11-1 may be configured with a known structure, and detailed description thereof will be omitted.

[0115] The first side wall 10-1 is integrally provided with a shaft 10A-1 that is rotatable relative to the bottom wall component 30-1. The shaft 10A-1 has a similar structure to the shaft 23-1 provided on the second side wall 20-1 but is narrower in the left-right direction, so a detailed description will be omitted. The first side wall 10-1 is rotatably attached to each bearing recess 33-1 of the bottom wall component 30-1 via the shaft 10A-1.

[0116] (Second side wall) 14, the second side wall 20-1 is integrally provided with a pair of shafts 23 configured to be rotatable relative to the bottom wall constituent part 30. The second side wall 20-1 also has an information display part 21.

[0117] (Information display section) The information display unit 21-1 is configured to be usable as an information display area. More specifically, the information display unit 21-1 is partitioned by a pair of horizontal walls 211-1 and a pair of vertical walls 212-1, and the inner surfaces of the pair of horizontal walls 211-1 and the pair of vertical walls 212-1 are connected to the flat plate portion 210-1. The area surrounded by the pair of horizontal walls 211-1, the pair of vertical walls 212-1, and the flat plate portion 210-1 is configured to be usable as an information display area.

[0118] The pair of horizontal walls 211-1 each extend in the left-right direction and have a width extending outward from the upper and lower edges (flat plate portion 210-1) of the second side wall 20-1. The pair of vertical walls 212-1 each extend in the up-down direction and have a width extending outward from both vertically aligned edges of the flat plate portion 210-1. The left-right length of the pair of horizontal walls 211-1 is formed to be approximately equal to the distance between a pair of wide bearing recesses 33A-1 provided at both ends of the upper end surface of the second base portion 320-1.

[0119] Of the pair of side walls 211-1, the lower one has a pair of locking projections 25-1 protruding downward on its underside. The pair of locking projections 25-1 are provided at positions facing the respective locking holes 34-1 formed in the upper end surface of the second base portion 320-1 when the pair of second side walls 20-1 are attached to the bottom wall constituent portion 30-1 and the pair of second side walls 20-1 are in an upright state, and are fitted into the respective locking holes 34-1. This prevents the second side walls 20-1 from tilting inward when the container 1-1 is in an assembled state.

[0120] 12 and 14, a pair of recesses 26-1, which are generally rectangular in front view and recessed to a predetermined depth toward the front, are provided on the lower edge of the rear side surface of the flat plate portion 210-1 at positions facing the pair of locking protrusions 25-1. The depth of each recess 26-1 is greater than the protruding height of each second stopper 34B-1 formed on the upper end surface of the second base portion 320-1.

[0121] The information displayed on the information display unit 21-1 is, for example, various information such as the name of the item stored in the container 1-1, the number of items, the destination of the container 1-1, and the location of the item / container 1-1. This information is displayed or stored on, for example, paper, a resin plate such as plastic, a sign, a card, a wireless tag (sometimes called an electronic tag, RFID tag, IC tag, contactless tag, smart card, etc.), etc., and is locked to the information display unit 21-1 by being sandwiched between the locking member 40 (including the locking member 61-1) and the flat plate portion 210-1. Various information may be locked (held) by the locking member 40 alone.

[0122] The information display unit 21-1 may be provided on at least one of the pair of second side walls 20-1. For example, the information display unit 21-1 may be provided only on the second side wall 20-1 attached to the front side of the container 1-1, and the information display unit 21-1 may not be provided on the second side wall 20-1 attached to the rear side of the container 1-1.

[0123] (shaft) 14, the second side wall 20-1 has a pair of shafts 23-1 that are rotatable relative to the bottom wall component 30-1 and extend downward from the lower side of the second side wall 20-1 in the horizontal direction (left-right direction), sandwiching the information display unit 21-1 (flat plate portion 210-1) therebetween. The shafts 23-1 are rotatably connected to the wide bearing recess 33A-1 of the second base portion 320-1.

[0124] The shaft portion 23-1 has a pair of engagement protrusions 23A-1 that protrude in the left-right direction from both left-right side surfaces of the lower end portion. The pair of engagement protrusions 23A-1 of each shaft portion 23-1 is inserted from above into the wide bearing recess 33A-1 of the second base portion 320-1 and is held rotatably around an axis along the longitudinal direction of the second base portion 320-1. Therefore, the shaft portion 23-1 is rotatably connected to the wide bearing recess 33A-1 via the pair of engagement protrusions 23A-1.

[0125] (Assembly and folding of the container) As described above, the first side wall 10-1 and the second side wall 20-1 are rotatably attached to the bottom wall constituent part 30-1 via the shafts 10A-1 and 23-1, respectively. This allows the container 1-1 to change state from an assembled state in which the pair of first side walls 10-1 and the pair of second side walls 20-1 are erected as shown in Fig. 12 to a folded state in which the pair of first side walls 10-1 and the pair of second side walls 20-1 are folded inward as shown in Fig. 15.

[0126] In embodiment 2, the locking mechanism 11-1 provided on the first side wall 10-1 is operated to switch from a locked state to an unlocked state, and then the pair of first side walls 10-1 are folded inward, and then the pair of second side walls 20-1 are folded inward to enter the folded state.

[0127] When the pair of second side walls 20-1 are folded as shown in Fig. 15, the lower edge of the information display unit 21-1 is positioned outward of the second base portion 320-1, i.e., the inner edge 320A-1 of the base portion 32-1, when viewed from above as shown in Fig. 16. Specifically, the horizontal wall 211-1 constituting the lower edge of the information display unit 21-1 faces the outer edge of the second base portion 320-1 along the longitudinal direction in the vertical direction. Furthermore, each second stopper 34B-1 protruding upward from the upper end surface of each second base portion 320-1 is received in each recess 26-1 of the second side wall 20-1.

[0128] In addition, in embodiment 2, as shown in Figure 16, when the pair of second side walls 20-1 are folded, when the container 1-1 in the folded state is viewed in a plane, the boundary with the horizontal wall 211-1 and a part of the flat portion 210-1 face the second base portion 320-1 in the vertical direction and are located outward of the inner edge 320A-1 of the base portion 32-1.

[0129] 17, the container 1-1 is assembled by first raising the pair of second side walls 20-1 in the folded state and then raising the pair of first side walls 10-1. In this case, the lower lateral wall 211-1 constituting the information display unit 21-1 of each second side wall 20-1 faces the upper end surface of the second base portion 320-1, and a pair of locking projections 25-1 (see FIG. 14) protruding downward from the lower surface of the lateral wall 211-1 are fitted into a pair of locking holes 34-1 (see FIG. 13) formed in the upper end surface of the second base portion 320-1.

[0130] (Action and effect) A container 1 according to aspect 5 of the present disclosure is any of aspects 1 to 4 above, wherein the second side wall 20-1 provided with the information display unit includes shaft portions (10A-1, 23-1) extending downward from the underside of the second side wall 20-1 with the information display unit 21-1 sandwiched therebetween, and the container 1-1 is configured such that, when the pair of first side walls 10-1 and the pair of second side walls 20-1 are in an upright assembled state, the pair of first side walls 10-1 and the pair of second side walls 20-1 are in an upright state and the pair of first side walls 10-1 and the pair of second side walls 20-1 are in an upright state, the pair of first side walls 10-1 and the pair of second side walls 20-1 are in an upright state ... first side walls 10-1 and the pair of second side walls 20-1 are in an upright state and the pair of second side walls 20-1 are in an upright state and the pair of first side walls 10-1 and the pair of second side walls 20-1 are in an upright state and the pair of first side walls 10-1 and the pair of second side walls The container 1-1 may be configured so that it can be displaced into a folded state in which the wall 20-1 is folded inward, and when viewed from above in the folded state, the lower edge of the information display unit 21-1 is positioned outward of the inner edge 320A-1 of the base portion (second base portion 320-1) that extends upward from the side edge of the bottom wall component 30-1 to which the second side wall 20-1 having the information display unit 21-1 is attached.

[0131] According to the above configuration, the vertical length of information display unit 21-1 that can be used as an information display area can be increased by the length of the bottom edge of information display unit 21-1 that protrudes outward from second base 320-1, i.e., from inner edge 320A-1 of base 32-1. This allows for a container with a wider area available as an information display area than conventional containers.

[0132] (Variation) A description will be given of a modified example of embodiment 2. In the following description, for the sake of convenience, members having the same functions as those described in embodiment 2 will be denoted by the same reference numerals, and the description thereof will not be repeated.

[0133] For example, as shown in FIG. 21 , of the pair of side walls 211-1 constituting the information display unit 21-1 of the second side wall 20-1, the lower side wall 211-1 may include a fixing portion 211A-1 for fixing a locking member 61-1 that locks information displayed in the information display area. The locking member 61-1 and the fixing portion 211A-1 may have corresponding locking and fixing structures, respectively, and the locking and fixing structures may be formed in any shape. In the example shown in FIG. 21 , protrusions are provided on both ends of the lower side of the locking member 61-1, and the protrusions are fixed to the fixing portion 211A-1. Information (such as paper, a resin plate such as plastic, a sign, or a card) is sandwiched between the locking member 61-1 and the flat plate portion 210-1. This allows the information displayed in the information display area to be locked by the locking member 61-1, thereby preventing the information displayed on the information display unit 21-1 from being lost during transportation of the container 1-1.

[0134] The fixing portion 211A-1 for fixing the locking member 61-1 may be provided on the horizontal wall 211-1 located on the upper side. Alternatively, it may be provided on either or both of the pair of vertical walls 212-1. Examples of the locking member 61-1 include a card holder and a wireless tag holder. Furthermore, when the extension wall 45-1 is provided as in the second embodiment, the fixing portion 211A-1 may be provided so as to face the extension wall 45-1 in the front-rear direction when the container is assembled. This can protect the fixing portion 211A-1 for fixing the locking member 61-1. Therefore, damage due to external contact, etc. can be prevented. Preferably, the height of the upper end of the extension wall 45-1 is equal to or greater than the height of the upper end of the fixing portion 211A-1.

[0135] (Embodiment 3) Next, a container 41-1 according to embodiment 3 will be described with reference to Figures 18 to 20. For ease of explanation, members having the same functions as those described in the container 1-1 according to embodiment 2 above will be denoted by the same reference numerals, and their description will not be repeated.

[0136] A container 41-1 according to embodiment 3 has substantially the same configuration as the container 1-1 according to embodiment 2. However, as shown in Fig. 18, the container 41-1 has a bottom wall forming portion 42-1 instead of the bottom wall forming portion 30-1. Also, the container 41-1 has a pair of second side walls 50-1 instead of the pair of second side walls 20-1.

[0137] (Extended wall) The configuration of the bottom wall constituent portion 42-1 will be described with reference to Fig. 19. As shown in Fig. 19, the bottom wall constituent portion 42-1 has substantially the same configuration as the bottom wall constituent portion 30-1, except that the pair of second base portions 320-1 of the bottom wall constituent portion 42-1 do not have the locking hole 34-1, first retainer 34A-1, or second retainer 34B-1 on their upper end surfaces. Each second base portion 320-1 also has an extension wall 45-1 that extends upward across the entire longitudinal width from the outer edge of the upper end surface sandwiched between the pair of wide bearing recesses 33A-1.

[0138] The height of the extension wall 45-1 from the upper end surface of the second base portion 320-1 is set to be slightly lower than the height of the wide bearing recess 33A-1 from the upper end surface of the second base portion 320-1. The outer surface of each extension wall 45-1 is formed to be flush with the outer surface of each second base portion 320-1. Further, at both longitudinal ends of the upper end surface of the second base portion 320-1 sandwiched between the pair of wide bearing recesses 33A-1, through holes 46-1 that are elongated and rectangular in plan view are formed along the inner base end of the extension wall 45-1.

[0139] (Information display section) The configuration of the second side wall 50-1 will be described with reference to Figures 18 and 20. As shown in Figures 18 and 20, the second side wall 50-1 has substantially the same configuration as the second side wall 20-1. However, the second side wall 50-1 is provided with an information display section 51-1 that can be used as an information display area, instead of the information display section 21-1. The information display section 51-1 has a side wall 511-1 that protrudes downward and has a U-shaped cross section, instead of the elongated plate-shaped side wall 211-1 below the information display section 21-1.

[0140] Therefore, the information display unit 51-1 is partitioned by an upper horizontal wall 211-1 that is long in the left-right direction and has a flat plate shape, a lower horizontal wall 511-1 that protrudes downward with a U-shaped cross section, and a pair of vertical walls 212-1 that extend in the up-down direction and connect both ends of each horizontal wall 211-1 and horizontal wall 511-1. The inner surfaces of each horizontal wall 211-1, horizontal wall 511-1 and the pair of vertical walls 212-1 are connected to the flat plate unit 210-1.

[0141] The lower lateral wall 511-1, which protrudes downward and has a U-shaped cross section, has a slit 511A-1 formed at the lower end thereof over almost the entire length in the longitudinal direction. The width of the slit 511A-1 is determined so that, for example, a resin plate such as paper or plastic can be inserted therethrough.

[0142] Note that a pair of fixing portions (having the same structure as the fixing portions 22, 211A-1 described above, and therefore detailed description thereof will be omitted) may be provided at both ends of the horizontal wall 511-1 to fix fixing members (having the same structure as the fixing members 40, 61-1 described above, and therefore detailed description thereof will be omitted) that fix information displayed in the information display area. In this case, the pair of fixing portions may be provided longitudinally with the slit 511A-1 sandwiched therebetween. Furthermore, the pair of fixing portions may, for example, divide the information display area in the left-right direction, with the left or right area being an area where information is displayed by the fixing portions, and the left or right area where no fixing portions are provided being an area where information is inserted by the slit 511A-1. In other words, information may be displayed in the information display area using both the fixing portions and the slit 511A-1.

[0143] When displaying information on the fixed portion, the information may be sandwiched between the locking member and the flat plate portion 210-1 and thereby locked to the information display portion 51-1. Various information may be locked (held) by the locking member alone.

[0144] (Action and effect) The assembled state of the container 41-1 configured as described above will be described with reference to FIG. 18. As shown in FIG. 18, when the second side wall 50-1 is assembled, the outer upper edge of the lower horizontal wall 511-1 of the information display unit 51-1, which can be used as an information display area, is disposed in contact with or in close proximity to the inner upper end surface of the extension wall 45-1 extending upward from the outer edge of the second base 320-1. A gap of a predetermined height is formed between the lower end of the horizontal wall 511-1, which protrudes downward and has a U-shaped cross section and is provided at the lower edge of the information display unit 51-1, and the upper end surface of the second base 320-1. A slit 511A-1 is formed along the entire length of the lower end of the horizontal wall 511-1, which protrudes downward and has a U-shaped cross section and is provided at the lower edge of the information display unit 51-1.

[0145] As a result, it becomes possible to insert and arrange cardboard or a resin plate such as plastic on which information is displayed into the downwardly protruding U-shaped cross-sectional gap formed by the lower lateral wall 511-1 of the information display unit 51-1 and the extension wall 45-1. Furthermore, it becomes possible to insert cardboard or a resin plate such as plastic on which information is displayed into the slit 511A-1 provided at the lower end of the lower lateral wall 511-1 of the information display unit 51-1, thereby preventing the loss of information displayed on the information display unit 51-1 during transport of the container 41-1, for example.

[0146] Furthermore, even if the containers 41-1 collide with each other when they are transported while arranged adjacent to each other, the lower lateral wall 511-1 of the second side wall 50-1 is protected by the extension wall 45-1. Therefore, the information held on the information display unit 51-1 can be prevented from falling off or being damaged.

[0147] The present disclosure is not limited to the above-described embodiments, and various modifications are possible within the scope of the claims. Embodiments obtained by appropriately combining the technical means disclosed in different embodiments are also included in the technical scope of the present disclosure. [Explanation of symbols]
