[0009] 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 component 30 comprises a substantially rectangular bottom surface 31, a pair of first base portions 310 extending upward from each side edge of the bottom surface 31 and to which a pair of first side walls 10 are attached, and a pair of second base portions 320 to which a pair of second side walls 20 are attached.

[0012] 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 shapes correspond to each other, when assembled as described below, the first side walls 10 and the first base portions 310 form a substantially integrated side wall. Also, the second side walls 20 and the second base portions 320 form a substantially integrated side wall.

[0013] 2, the bottom wall constituent part 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 part 310 and the second base part 320, respectively. The long bearing recesses 33A are provided near each corner of the bottom wall constituent part 30.

[0014] In other words, it can be said that long bearing recesses 33A are provided at both end portions of the pair of second base portions 320. Furthermore, bearing recesses 33 are provided between both end portions of second base portion 320. When arranging long bearing recesses 33A and bearing recesses 33 as described above, both end portions of second base portion 320 are designed to be higher in the up-down direction than the space between both end portions of second base portion 320.

[0015] In other words, the vertical height between both ends of the second base portion 320 is lower than that of both ends of the second base portion 320. The placement locations and numbers of the bearing recesses 33 and the long bearing recesses 33A may be set appropriately depending on the size of the container 1 and the respective lengths of the first base portion 310 and the second base portion 320, etc. The second base portion 320 may be higher in the vertical direction than the first base portion 310. The long bearing recesses 33A are designed to be longer in the vertical direction than the bearing recesses 33.

[0016] 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] It is not essential that the vertical height of the second base portion 320 provided with the extension wall 34 be one step lower than the vertical height of the second base portion 320 not provided with the extension wall 34. In other words, the vertical height may be designed to be the same as the vertical height of the second base portion 320 not provided with the extension wall 34.

[0021] 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.

[0022] The bottom wall forming portion 30 has stacking recesses 35 at each corner portion on the upper side of the bottom wall forming portion 30. The bottom wall forming portion 30 also has stacking protrusions 36 that extend downward from below 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.

[0023] The stacking recess 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 both the first base portion 310 and the second base portion 320.

[0024] 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.

[0025] 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, which will be described later). 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.

[0026] (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.

[0027] 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.

[0028] (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).

[0029] (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.

[0030] It should be noted that the horizontal wall 211 only needs to be provided below the second side wall 20 in the up-down direction, and in this case, the pair of vertical walls 212 may not be provided.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] The information displayed on the information display unit 21 is not limited to information that is locked by the locking member 40 described below, but may also be information that is displayed by, for example, directly attaching a sticker or the like to the information display area, or by directly engraving, printing, printing, etc.

[0037] 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.

[0038] 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.

[0039] (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.

[0040] 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 Figure 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] The fixing portion 22 for fixing the locking member 40 that locks the information displayed in the information display area may be provided on the upper horizontal wall 211 of the pair of horizontal walls 211. Also, 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.

[0045] (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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] The arrangement location and number of the shaft portions 23 may be determined 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. Note that the long shaft portion 23B is not an essential component of the shaft portion 23 provided on the first side wall 10. In other words, the shaft portion 23 provided on the first side wall 10 may be the short shaft portion 23A only.

[0050] Furthermore, the long shaft portion 23B is not an essential component of the second side wall 20 either. That is, the shaft portion 23 provided on the second side wall 20 may be only the short shaft portion 23A.

[0051] 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.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] (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 portion 30 via the shaft portion 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. 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).

[0056] 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.

[0057] 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.

[0058] 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.

[0059] 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.

[0060] In this case, in the assembled state, the lower sides of the pair of second side walls 20 rest on the second base portion 320, so it is necessary to move the lower-positioned lateral wall 211 upward by the amount corresponding to the increase in the vertical height of the bearing recess 33. If the lower-positioned lateral wall 211 is moved upward, the vertical length of the information display unit 21 will be shortened (it is necessary to cut out the lower end of the information display unit 21 by the amount corresponding to the increase in the vertical height of the bearing recess 33, and to install the lower-positioned lateral wall 211 at a position corresponding to the height of the second base portion 320).

[0061] In other words, the vertical height of the bearing recess 33 can be made lower than when the short shaft portion 23A is not separated from the bearing recess 33, so the vertical (particularly downward) length of the information display portion 21 can be increased, and the information display area can be made wider.

[0062] Furthermore, by having the short shaft portion 23A disengaged from the bearing recess 33, it is possible to prevent the vertical height of the container 1 in the folded state (the height of the second base portion 320) from increasing even when the second side wall 20 is folded after the first side wall 10 is folded. This makes it possible to widen the information display area of ​​the information display portion 21 in the vertical direction (particularly downward) when the second side wall 20 is in the upright state.

[0063] When the second side wall 20 is folded as described above, the short shaft portion 23A is detached from the bearing recess 33, and as shown in Figure 5, the lower end of the detached short shaft portion 23A is positioned opposite the extension wall 34 in the front-to-rear direction.

[0064] In this way, the lower end of the short shaft portion 23A is positioned opposite the extension wall 34, so that the short shaft portion 23A can be protected even when the short shaft portion 23A is detached from the bearing recess 33. This prevents damage due to external contact, etc. Furthermore, it is possible to restrict outward movement of the second side wall 20. In other words, it is possible to prevent the second side wall 20 from falling off outward.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] When the container 1 transitions to the folded state, it first folds the pair of first side walls 10 and then folds the pair of second side walls 20. When the pair of first side walls 10 are in the folded state and the pair of second side walls 20 are in the upright state (see FIG. 7), the lower ends of the shaft portions 23 of the pair of second side walls are positioned below the outer surface T of the first side walls 10.

[0078] Therefore, when folding the pair of second side walls 20 that are folded later, they are folded while coming into contact with the pair of first side walls 10 that were folded earlier. Therefore, guide portions with inclined surfaces may be provided on the pair of first side walls 10 at the portions where the pair of second side walls 20 that are folded later come into contact so that the pair of second side walls 20 can be folded smoothly.

[0079] The guide portions are provided at positions horizontally facing the shaft portions 23 of the pair of second side walls 20 in the standing state when the pair of first side walls 10 are folded. The "portions with which the pair of second side walls 20 come into contact when folded later" refers to, for example, outer edge portions in the width direction of the pair of first side walls 10 (left and right ends in the front-rear direction shown in FIG. 7). More specifically, it refers to portions of the outer edge portions in the width direction of the pair of first side walls 10 after folding that correspond to positions that overlap with the rotation ranges of the shaft portions 23 provided on the pair of second side walls 20.

[0080] The inclined surfaces provided on the guide portions are inclined so as to move away from the outer edges in the width direction of the pair of first side walls 10 after being folded as they move outward.

[0081] By providing the guide portion, when folding the pair of second side walls 20 that are folded later, the shaft portion 23 of the second side walls 20 slides against the guide portion, and the second side walls 20 (shaft portion 23) can be guided upward and in the folding direction, so that the second side walls 20 can be folded relatively smoothly.

[0082] The guide portion is formed so as to cut out the outer surface T of the first side wall 10. More specifically, the guide portion has an inclined shape so as to cut out the outer surface T of the first side wall 10 and the surface in the thickness direction (vertical direction). However, the guide portion is not limited to the shape and position described above. Furthermore, the guide portion may be provided on the shaft portion 23 of the second side wall 20 instead of or in addition to the first side wall 10. In this case, for example, the guide portion may be formed so as to recess the shaft portion 23 of the second side wall 20 in a dogleg shape. In other words, it is sufficient that something is formed to guide the second side wall 20, which is later folded onto the container 1, upward in the folding direction.

[0083] (Action and effect) As described above, according to this embodiment, the following advantageous effects can be obtained.

[0084] A container 1 according to a first aspect of the present disclosure is a container 1 including 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 has an information display portion 21 that can be used as an information display area, and a shaft portion 23 (short shaft portion 23A, long shaft portion 23B) configured to be rotatable with respect to the bottom wall component 30, and extends downward from the underside of the second side wall 20. and an axis portion 23 arranged at a position where an imaginary line Y perpendicular to a rotation axis direction X of at least one of the axis portions 23 overlaps with the information display portion 21 in the vertical direction, and the container 1 is capable of changing its state 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 axis portion 23 is located below the outer surface T of the first side wall 10.

[0085] According to the above configuration, the container 1 includes at least one shaft portion 23 disposed at a position where an imaginary line Y 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 surface T of the first side wall 10.

[0086] 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.

[0087] 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.

[0088] The container 1 according to aspect 2 of the present disclosure may be configured in the above-mentioned aspect 1 such that 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.

[0089] 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.

[0090] The container 1 according to aspect 3 of the present disclosure may be configured such that, in the above-mentioned aspect 1, the second side wall 20 has a horizontal wall 211 on the lower side of the second side wall 20 in the vertical direction, and the horizontal wall 211 has a fixing portion 22 for fixing a locking member 40 that locks the information displayed in the information display area.

[0091] According to the above configuration, the side wall 211 includes the fixing portion 22 for fixing the locking member 40 that locks the information displayed in the information display area. This allows the information to be displayed on the container 1 to be fixed to the information display portion 21.

[0092] 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]
