[0009] [Embodiment 1] Hereinafter, an embodiment of the present disclosure will be described in detail. In the following description, for convenience of explanation, the vertical direction, the horizontal direction, and the front-rear direction are defined as shown by the arrows in each figure. Also, the horizontal direction and the front-rear direction may be referred to as the "horizontal direction". Further, the direction from the inside to the outside of the container 1 is defined as "outward", and the direction from the outside to the inside of the container 1 is defined as "inward". Furthermore, "outward" and "inward" may be referred to as the "inside-outside direction". Also, furthermore, the front-rear direction may be referred to as the "inside-outside direction". In the following description, the "rectangular shape" does not necessarily refer to a strict rectangular shape, and includes, for example, a shape that can be visually recognized as a rectangular shape as a whole even if the corners are curved. Also, parts having the same function may be denoted by the same reference numerals and the description thereof may be omitted.

[0010] (Overview of the container) As shown in FIGS. 1 and 2, the container 1 includes a bottom wall component 30 having a substantially 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, for example.

[0011] (Bottom wall component) The bottom wall component 30 includes a substantially rectangular bottom surface 31, a pair of first base portions 310 that extend upward from each side of the bottom surface 31 and 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.

[0012] (Base portion) The shape of the upper side of the pair of first base portions 310 corresponds to the shape of the lower side of the pair of first side walls 10, and the shape of the upper side of the pair of second base portions 320 corresponds to the shape of the lower side of the pair of second side walls 20. By the corresponding shapes, when in the assembled state described later, the first side wall 10 and the first base portion 310 constitute a substantially integral side wall. Also, the second side wall 20 and the second base portion 320 constitute a substantially integral side wall.

[0013] (Bearing recess) As shown in Figure 2, the bottom wall component 30 has a plurality of bearing recesses 33 provided at predetermined intervals. More specifically, the plurality of bearing recesses 33 are provided at predetermined intervals in the first base portion 310 and the second base portion 320, respectively.

[0014] The bearing recesses 33 may be positioned and numbered 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 is designed to be taller in the vertical direction than the first base portion 310. The height of the second base portion 320 may be the same as that of the first base portion 310, or it may be designed to be shorter than that of the first base portion 310.

[0015] 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 shaft portion 23 of the second side wall 20, which will be described later.

[0016] Although the shaft portions 23 provided on the first side wall 10 and the second side wall 20 are designed to be the same length, the length of the shaft portions 23 may be changed as appropriate depending on the size, shape, etc., of the first base portion 310 and the second base portion 320. For example, the length of the shaft portion 23 provided on the first side wall 10 and the shaft portion 23 provided on the second side wall 20 may be different.

[0017] (First receptive area) The bottom wall component 30 includes a first receiving section 330 formed to be able to receive information to be displayed in the information display section 21, which will be described later. Specifically, a part of the bottom wall component 30 constitutes the first receiving section 330. The first receiving section 330 will now be described with reference to Figure 7. As shown in Figure 7, the first receiving section 330 includes a lower receiving wall 331, an inner receiving wall 332 extending upward from the rear end of the lower receiving wall 331, and an outer receiving wall 333 extending upward from the front end of the lower receiving wall 331.

[0018] As described above, the first receiving portion 330 is divided into a lower receiving wall 331, an inner receiving wall 332, and an outer receiving wall 333, and is open at the top, forming a U-shaped groove in cross-section.

[0019] More specifically, the second base portion 320 on which the first receiving portion 330 is formed includes, as shown in Figures 2 and 7, a base outer wall 321, a base inner wall 334 that faces the base outer wall 321 inward in the inward direction and is connected to the bottom surface 31, and a base upper wall 335 that connects the upper part of the base outer wall 321 and the base inner wall 334.

[0020] Furthermore, the outer side of the base upper wall 335 is recessed in a crank shape to form the inner receiving wall 332 and the lower receiving wall 331. A first protective wall 322 (outer receiving wall 333), described later, is provided on the outer side of the lower receiving wall 331, and the first receiving portion 330 is formed by the area surrounded by the inner receiving wall 332, the outer receiving wall 333 (first protective wall 322), and the lower receiving wall 331.

[0021] Furthermore, the inner receiving wall 332 (including the base upper wall 335), the side wall 211 (side wall end 2110), and a portion of the convex portion 24 (inclined portion 240) face the first protective wall 322 (base outer wall 321) in the front-rear direction.

[0022] Furthermore, the second base portion 320, in which the bearing recess 33 is formed, has a base outer wall 321 and a base inner wall 334 that faces the base outer wall 321 inward in the inward direction and is connected to the bottom surface 31, as shown in Figure 2 (see also Figure 6). The upper end of the base inner wall 334 is connected to the bottom surface of the bearing recess 33.

[0023] Furthermore, the bottom surface of the bearing recess 33 is connected to a position approximately midway in the vertical direction of the base outer wall 321. The term "approximately midway position" does not mean a position limited to the exact midway point, but rather includes positions shifted upward or downward from the midway point in the vertical direction of the base outer wall 321. .

[0024] Furthermore, the lower part of the shaft portion 23, from the lower shaft portion wall 2310 described later, faces the foundation outer wall 321 in the front-rear direction, while the second receiving portion 231, the inner shaft portion wall 2311, the side wall 211 (side wall end 2110), and a part of the side wall 211 (inclined portion 240) face the first protective wall 322 (foundation outer wall 321) in the front-rear direction.

[0025] The first receiving portion 330 extends in the left-right direction, as shown in Figure 2. At least one first receiving portion 330 is required to be provided in the bottom wall component 30. In this embodiment, two first receiving portions 330 are provided in each of the bottom wall component 30 (a pair of second base portions 320) at positions corresponding to below the information display portion 21, which will be described later.

[0026] More specifically, the first receiving portion 330 is positioned between multiple bearing recesses 33, which are arranged below the information display unit 21 in a similar manner to the first receiving portion 330. In other words, the multiple bearing recesses 33 arranged below the information display unit 21 are positioned with the first receiving portion 330 in between. The upper part of the first receiving portion 330 and the upper part of the bearing recesses 33 are in horizontal communication. More specifically, the opening formed above the first receiving portion 330 and the opening formed above the bearing recesses 33 are in horizontal communication.

[0027] Furthermore, the arrangement of the bearing recess 33 is not limited to the arrangement described above. For example, if the bearing recess 33 is not located below the information display unit 21, the first receiving portion 330 may be formed to have the same length as the left-right length of the information display unit 21. Alternatively, it may be formed by dividing it into multiple sections within the range of the left-right length of the information display unit 21.

[0028] (Foundation exterior wall) Returning to Figures 1 and 2, the bottom wall component 30 includes a base outer wall 321 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 base outer wall 321 constitutes the outer surface of the second base portion 320. In this embodiment, the base outer wall 321 is provided along the entire length of the second base portion 320 in the left-right direction. However, it is not limited to this, and the base outer wall 321 only needs to be provided in the second base portion 320 within the range where the first receiving portion 330 is provided.

[0029] (1st protection wall) The base outer wall 321 is provided with a first protective wall 322 (see Figures 6 and 7) on its upper side. The first protective wall 322 plays a role in protecting the first receiving section 330 from the outside, for example, when the containers 1 are transported side by side and collide with each other.

[0030] The first protective wall 322 is molded integrally with the base outer wall 321. Furthermore, a portion of the first protective wall 322 constitutes the outer receiving wall 333. In other words, the base outer wall 321 and the first protective wall 322 (outer receiving wall 333) constitute a part of the second base section 320, and the second base section 320, the base outer wall 321, and the first protective wall 322 (outer receiving wall 333) are molded integrally. The first receiving section 330, the base outer wall 321, and the first protective wall 322 are provided on the second base section 320, but they may also be provided on the first base section 310, or on both the first base section 310 and the second base section 320. Details of the arrangement of the second base section 320, the first protective wall 322, and the first receiving section 330 will be described later.

[0031] (Stacking recess) The bottom wall component 30 is provided with stacking recesses 35 at each corner portion on the upper side of the bottom wall component 30. Furthermore, the bottom wall component 30 extends downward from below the bottom surface 31, and stacking The container is equipped with stacking protrusions 36 that are received in the recess 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 recess 35.

[0032] The stacking recess 35 may be provided only in the first base portion 310, or only in the second base portion 320, or it may be provided so as to span both the first base portion 310 and the second base portion 320.

[0033] The stacking protrusions 36 are received by the stacking recesses 35, thereby restricting the horizontal movement of the stacked containers 1. Note that the containers 1 stacked on top of each other can be stacked regardless of whether the containers 1 are in a folded or assembled state, as described later. Furthermore, the shapes of the stacking recesses 35 and stacking protrusions 36 may be molded into any shape that allows for stacking.

[0034] Furthermore, when the pair of first side walls 10 and the pair of second side walls 20 are in an upright position, each corner portion of the container 1 is also provided with stacking recesses 12 (see Figure 1). Similar to the stacking recesses 35 described above, the stacking protrusions 36 of the upper container are received in the stacking recesses 12 when the containers 1 are stacked vertically (the lower container 1 is in an assembled state, which will be described later). The stacking recesses 12 may be provided only on the first side walls 10, or only on the second side walls 20, or they may be provided to span both the first side walls 10 and the second side walls 20.

[0035] (First side wall) As shown in Figure 1, the first side wall 10 is equipped 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 switching 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 can be composed of any known structure, and its arrangement on the first side wall 10 is not limited, so a detailed explanation is omitted.

[0036] The first side wall 10 integrally includes a shaft portion 23 (see Figure 5) configured to be rotatable relative to the bottom wall component 30 (first base portion 310). The shaft portion 23 has the same shape and structure as the shaft portion 23 of the second side wall 20, and details will be described later. The first side wall 10 is rotatably attached to the bearing recess 33 of the bottom wall component 30 (first base portion 310) via the shaft portion 23.

[0037] (Second side wall) As shown in Figures 3 and 4, the second side wall 20 includes an information display section 21, a fixing section 22, and a shaft section 23.

[0038] (Information display section) The information display unit 21 is an information display area, and the information displayed on the information display unit 21 is 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 and container 1. This information is displayed or stored on, for example, paper, plastic or other resin plates, Kanban, cards, wireless tags (sometimes called electronic tags, RFID tags, IC tags, contactless tags, smart cards, etc.), and is locked to the information display unit 21 by being sandwiched between the locking member 40 and the base unit 210, as described later. Various types of information may also be locked (held) by the locking member 40 alone.

[0039] The information displayed on the information display unit 21 is not limited to information that is locked by the locking member 40 described later. It may also be information that is directly attached to the information display area, such as a sticker, or that is directly displayed by engraving, printing, or other means.

[0040] The information display unit 21 only needs to 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 of the container 1, and not on the second side wall 20 attached to the rear of the container 1.

[0041] 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 in accordance with the information displayed on the information display unit 21. Also, the position of the information display area of ​​the information display unit 21 is not particularly limited. It may be located in a corner (corner of the container 1) in the horizontal (left-right) direction, or there may be multiple such areas arranged horizontally (left-right).

[0042] The information display unit 21 includes a base unit 210 that can be used as an information display area. The base unit 210 is composed of flat surfaces extending vertically and horizontally from the second side wall 20. The information display unit 21 is divided 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 base unit 210.

[0043] Each pair of horizontal walls 211 extends in the left-right direction and has a width extending outward from the side surface (base portion 210) of the second side wall 20. Each pair of vertical walls 212 extends in the up-down direction and has a width extending outward from the side surface (base portion 210) of the second side wall 20.

[0044] More specifically, of the pair of side walls 211, the lower side wall 211 extends outward from the lower end of the base portion 210, and the upper side wall 211 extends outward from the upper end of the base portion 210.

[0045] Furthermore, the pair of vertical walls 212 extend outward from the left and right ends (positions near the edges) of the base portion 210. The information display unit 21 is configured so that the area enclosed by the pair of horizontal walls 211, the pair of vertical walls 212, and the base portion 210 can be used as an information display area. In other words, the information display area is formed by the pair of horizontal walls 211, the pair of vertical walls 212, and the base portion 210.

[0046] Of the pair of horizontal walls 211, the lower horizontal wall 211 extends less in the front-to-back direction than the upper horizontal wall 211, and is formed as if a portion is cut out along its entire length in the left-to-right direction between the pair of vertical walls 212. The horizontal wall 211 formed in this way has a horizontal wall end 2110 at its outer end. Note that the horizontal walls 211 and vertical walls 212 may also be provided in areas other than the information display area (other locations).

[0047] The side wall 211 only needs to be provided on the lower side in the vertical direction of the second side wall 20, and in this case, the pair of vertical walls 212 do not need to be provided. The structure of the second side wall 20 described above may be provided on the first side wall 10, or on both the first side wall 10 and the second side wall 20.

[0048] As described above, the inclusion of the side wall 211 improves the rigidity of the base portion 210 in the inward and outward directions. Furthermore, since the side wall end portion 2110, which is the outer end of the side wall 211, is formed to be located inward from the base outer wall 321, the side wall end portion 2110 can also serve as a guide to direct cards or other items displaying information to be inserted into the information display portion 21 to the first receiving portion 330.

[0049] (Convex part) The base portion 210 is provided with a convex portion 24 that protrudes outward in the inward and outward directions from a flat surface. More specifically, the convex portion 24 is formed to protrude outward from the base portion 210 in a cross-sectional view of the base portion 210 cut lengthwise (see Figure 6). As shown in Figure 4, the convex portion 24 is formed in a roughly triangular shape in a side view from the left and right directions. The convex portion 24 is an example of a guide portion.

[0050] The convex portion 24 is positioned below the base portion 210, and its lower end is connected to the lower side wall 211. In other words, the convex portion 24 also functions as a rib connecting the side wall 211 and the base portion 210, playing a role in increasing the rigidity of the information display area.

[0051] Furthermore, the convex portion 24 is equipped with an inclined portion 240 that is molded such that the amount of outward protrusion increases as it extends downward in the vertical direction. The inclined portion 240 is molded integrally with the convex portion 24 and is the end face of the convex portion 24 that is exposed on the outward side. The inclined portion 240 is an example of a guide portion.

[0052] The shape of the convex portion 24 is not limited to the shape described above. For example, when viewed from the left or right, it may be formed into a roughly rectangular shape, a polygonal shape, or a shape with an R-shaped curved surface. The inclined portion 240 may be designed as appropriate to match the shape of the convex portion 24. In other words, the inclined portion 240 is not an essential component. The number of convex portions 24 may also be adjusted as appropriate. At least one convex portion 24 is provided on the base portion 210.

[0053] (Fixed part) As shown in Figures 3 and 4, the pair of vertical walls 212 constituting the information display unit 21 are equipped with fixing parts 22 for fixing a locking member 40 that locks the information displayed in the information display area. The locking member 40 and the fixing part 22 only need to have corresponding locking and fixing structures, and the shapes of the locking and fixing structures can be molded into any shape.

[0054] In the example shown in Figures 3 and 4, plate-shaped fixed portions 41, molded to match the shape of the fixing portion 22, are provided at both ends of the locking member 40 in the left-right direction. By pushing the locking member 40 in the direction of the arrow in Figure 4 (from front to back), the fixed portions 41 are fixed to the fixing portion 22. Examples of locking members 40 include card holders and wireless tag holders.

[0055] The shape and size of the locking member 40 may be appropriately designed based on the shape of the second side wall 20, the shape of the information display section 21, etc. In this embodiment, the locking member 40 has a flat plate-shaped base 42 on which the fixed portion 41 is provided sandwiched between it, and on the upper side a locking wall 43 that is shaped to incline toward the base portion 210, and on the lower side a second protective wall 44 that extends downward from the base 42.

[0056] (Second protection wall) As shown in Figure 4, the locking member 40 is equipped with a second protective wall 44. The second protective wall 44 is provided on the underside of the flat base of the locking member 40. The second protective wall 44 plays a role in protecting the convex portion 24, the inclined portion 240, and the first receiving portion 330 from the outside, for example, when transporting containers 1 lined up next to each other and the containers 1 collide with each other.

[0057] The second protective wall 44 is molded integrally with the locking member 40. In other words, the second protective wall 44 constitutes a part of the locking member 40. Furthermore, the second protective wall 44, which is a part of the locking member 40, may also constitute a part of the first receiving portion 330.

[0058] As shown in Figures 6 and 7, the outer surface of the second protective wall 44 is located inward from the outer surface of the base outer wall 321 (first protective wall 322, outer receiving wall 333). For example, when transporting containers 1 lined up next to each other, even if the containers 1 collide with each other, it is possible to prevent the adjacent containers 1 from coming apart by hitting or getting caught on the second protective wall 44.

[0059] The outer surface of the second protective wall 44 (locking member 40) may be located on the same plane (flush surface) as the outer surface of the base outer wall 321 (first protective wall 322, outer receiving wall 333), or it may be located outward from the outer surface of the base outer wall 321 (first protective wall 322, outer receiving wall 333). The second protective wall 44 is not an essential component, and the locking member 40 does not need to be equipped with the second protective wall 44.

[0060] (Shaft section) The second side wall 20 integrally includes a shaft portion 23 that is rotatably configured relative to the bottom wall component 30 (second base portion 320). As shown in Figure 3, the shaft portion 23 extends downward from the lower side of the second side wall 20 and is provided in multiples at predetermined intervals in the left-right direction. The shaft portion 23 of the first side wall 10 has the same structure as the shaft portion 23 provided on the second side wall 20, extending downward from the lower side of the first side wall 10 and provided at predetermined intervals in the left-right direction.

[0061] The shaft portion 23 is provided with a curved shaft portion inclined surface 230 formed with a predetermined curvature. The shaft portion inclined surface 230 plays a role in smoothing the sliding between the shaft portion inclined surface 230 and the surface facing it in the bearing recess 33. Note that the shaft portion inclined surface 230 is not limited to a curved inclined surface; the inclined surface may be formed in a polygonal shape so as to be substantially curved.

[0062] The placement and number of shaft portions 23 may be determined as appropriate based on the length and size of the second side wall 20 in the left-right direction. The second side wall 20 is rotatably attached to the bearing recess 33 of the bottom wall component 30 (second base portion 320) via the shaft portions 23. The shaft portions 23 are similarly provided on the first side wall 10.

[0063] Of the multiple shaft portions 23 provided on the second side wall 20, at least one shaft portion 23 is positioned below the information display unit 21 and overlapping with the information display unit 21 in the vertical direction. In this embodiment, there are three shaft portions 23 positioned below the information display unit 21 and overlapping with the information display unit 21 in the vertical direction.

[0064] Furthermore, the number of shafts 23 positioned below the information display unit 21 and overlapping with the information display unit 21 in the vertical direction is not limited to three; it may be one, four, or any other number, and can be set appropriately depending on the length and size of the second side wall 20 in the left-right direction.

[0065] Furthermore, the shaft portion 23, which is positioned below the information display unit 21 and overlapping with it in the vertical direction, is not an essential component. If the shaft portion 23 is not provided, it is sufficient to have a shaft portion 23 attached to the second base portion 320 on the lower side in the left-right direction of the second side wall 20, with the information display unit 21 in between.

[0066] (Second receptive area) In the vertical direction, the shaft portion 23, which is positioned below the information display unit 21 and overlapping with the information display unit 21, is equipped with a second receiving portion 231 that is formed to receive information displayed on the information display unit 21.

[0067] The second receiving portion 231 includes a lower shaft wall 2310 so as to be substantially flush with the lower receiving wall 331 of the first receiving portion 330 when the shaft portion 23 is received in the bearing recess 33. It also includes an inner shaft wall 2311 so as to be substantially flush with the inner receiving wall 332 of the first receiving portion 330. In other words, the second receiving portion 231 is composed of the lower shaft wall 2310 and the inner shaft wall 2311, and is formed to be able to receive information displayed on the information display portion 21 so as to be continuous with the first receiving portion 330 when the shaft portion 23 is received in the bearing recess 33. The inner shaft wall 2311 may be a flat surface or a rib.

[0068] By forming the second receiving portion 231 in this manner, the first receiving portions 330, which are separated by the bearing recess 33 as shown in Figure 2, can be connected by the second receiving portion 231. More specifically, the lower receiving walls 331, which are the lower surfaces of the first receiving portions 330, can be connected by the lower shaft wall 2310 of the second receiving portion 231. This allows the information (cards, etc.) displayed on the information display unit 21 to be stabilized.

[0069] Furthermore, the lower wall 2310 of the shaft portion is not limited to being approximately flush with the lower receiving wall 331; it may be molded to be lower in height than the lower receiving wall 331, or it may be molded to be higher in height than the lower receiving wall 331.

[0070] Furthermore, the inner wall 2311 of the shaft portion is not limited to being substantially flush with the inner receiving wall 332, but may be molded to be located inside the inner receiving wall 332 in the front-rear direction, or it may be molded to be located outside the inner receiving wall 332.

[0071] (Arrangement of foundation exterior wall, first receiving section, and base section) Here, the arrangement of the base outer wall 321, the first receiving portion 330, and the base portion 210 of the container 1 will be explained with reference to Figures 6 and 7.

[0072] As shown in Figures 6 and 7, the first receiving portion 330 and the base portion 210 are positioned inward from the outer surface of the base outer wall 321. More specifically, the base outer wall 321, the first receiving portion 330, and the base portion 210 of the container 1 are arranged in the following order from the outside of the container 1 (the front side in Figures 6 and 7): the base outer wall 321, the first receiving portion 330, and the base portion 210.

[0073] In this embodiment, a foundation outer wall 321 is provided on the outer side, with a first receiving portion 330 and a second receiving portion 231 in between, and a base portion 210 is provided on the inner side. More specifically, a first protective wall 322 (outer receiving wall 333) with the foundation outer wall 321 is provided on the outer side, and a side wall 211 (side wall end portion 2110) with the base portion 210 is provided on the inner side.

[0074] In other words, the first receiving portion 330 may be formed by a part of the second base portion 320 (base outer wall 321) and a part of the second side wall 20.

[0075] In Figures 6 and 7, the height of the upper end of the first protective wall 322 (outer receiving wall 333) is set higher than the vertical height of the side wall end 2110. The height of the upper end of the first protective wall 322 may be the same as or lower than the vertical height of the side wall end 2110.

[0076] The first protective wall 322 should be provided such that its upper end (outer receiving wall 333) is positioned higher than the lower receiving wall 331. By designing the first protective wall 322 (outer receiving wall 333) so that its upper end is positioned in this way, the outward movement of information (cards, etc.) displayed on the information display unit 21 can be restricted by the first protective wall 322 (outer receiving wall 333), and the information can be protected from external impacts, etc.

[0077] Furthermore, if the vertical height of the first protective wall 322 is reduced, the downward extension of the second protective wall 44 provided by the locking member 40 may be increased. For example, the height of the upper end of the first protective wall 322 may be the same as the height of the lower receiving wall 331 (the first protective wall 322 does not protrude upward from the lower receiving wall 331). In this case, the second protective wall 44 may be the outer receiving wall 333.

[0078] Furthermore, the first protective wall 322 and the second protective wall 44 may work together to protect the first receiving portion 330 and the second receiving portion 231. Also, if the second protective wall 44 is not provided on the locking member 40, the upward extension of the first protective wall 322 may be increased.

[0079] Furthermore, as shown in Figures 6 and 7, the side wall end portion 2110 is provided such that its position is substantially flush with the shaft inner wall 2311 and the inner receiving wall 332 in the vertical direction, and with respect to the front end portion in the front-rear direction. However, it is not limited to this position. For example, the side wall end portion 2110 may extend forward (outward) from the position shown in Figures 6 and 7.

[0080] In other words, the side wall end portion 2110 only needs to be located inward from the inner surface of the first protective wall 322 (outer receiving wall 333), and a gap should be formed from above the first receiving portion 330 and the second receiving portion 231 into which information to be displayed on the information display portion 21 can be inserted.

[0081] As described above, the container 1 is arranged with a base outer wall 321 (first protective wall 322, outer receiving wall 333), a first receiving portion 330, and a base portion 210 (side wall end portion 2110). This creates a vertically communicating hole (communication hole) between the side wall end portion 2110 and the base outer wall 321 (first protective wall 322, outer receiving wall 333).

[0082] In other words, in the assembled state described later, a removable hole (communication hole) for inserting and removing cards or the like, which are connected to the first receiving portion 330 and the second receiving portion 231, is formed between the second side wall 20 and the second base portion 320.

[0083] Since the hole (communication hole) is continuous in the vertical direction with the first receiving portion 330 and the second receiving portion 231, the side wall end portion 2110 may constitute a part of the first receiving portion 330 and the second receiving portion 231, and may also play the role of the first receiving portion 330 and the second receiving portion 231.

[0084] Then, through the hole (communication hole), a card or the like on which information is displayed is inserted up to the lower receiving wall 331 of the first receiving section 330 and the lower wall 2310 of the shaft portion of the second receiving section 231. As a result, the usable area for displaying information is expanded compared to conventional designs, allowing for more efficient use of the information display section 21, which is located in a limited space.

[0085] (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 component 30 via the shaft portion 23. As a result, the container 1 can change its state from an assembled state in which the pair of first side walls 10 and the pair of second side walls 20 are upright, as shown in Figure 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 Figure 5.

[0086] 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, 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 a 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 later.

[0087] During the process in which the pair of first side walls 10 and the pair of second side walls 20 are folded inward, the inclined surface 230 of the shaft slides along the inner surface of the bearing recess 33, thereby enabling the pair of first side walls 10 and the pair of second side walls 20 to fold smoothly.

[0088] The order in which the first side wall 10 and the second side wall 20 are folded is not limited to the order described above; 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.

[0089] (modified version) The following modifications can be applied to this embodiment as appropriate. Furthermore, these modifications may be combined with each other to the extent that they are not technically contradictory.

[0090] (Variation 1) In the embodiments described above, the second base portion 320 (base outer wall 321) is provided with a first protective wall 322, and the locking member 40 is provided with a second protective wall 44, but the configuration is not limited to this. For example, the second side wall 50 shown in Figures 8 and 9 is provided with a third protective wall 213.

[0091] The third protective wall 213 extends horizontally from the lower end of the information display section 21 so as to connect the pair of vertical walls 212. The third protective wall 213 has a roughly L-shaped cross-section and is positioned opposite the horizontal wall end 2110.

[0092] More specifically, the third protective wall 213 is positioned at a predetermined distance in front of (outward of) the side wall end 2110, such that a vertically communicating hole (communication hole) is formed between the third protective wall 213 and the side wall end 2110. The "predetermined distance" is sufficient if a gap is formed into which information to be displayed on the information display unit 21 can be inserted. In other words, it can be designed appropriately to suit the information to be inserted.

[0093] With the above configuration, when the second side wall 50 is assembled, a removable hole (communication hole) for inserting and removing cards or the like that display information connected to the first receiving portion 330 and the second receiving portion 231 is formed between the second side wall 50 and the second base portion 320.

[0094] Since the hole (communication hole) is continuous in the vertical direction with the first receiving portion 330 and the second receiving portion 231, the side wall end portion 2110 and the third protective wall 213 may constitute a part of the first receiving portion 330 and the second receiving portion 231, and may also play the role of the first receiving portion 330 and the second receiving portion 231.

[0095] Furthermore, the third protective wall 213 can also be described as being constructed by providing the hole (communication hole) at approximately the midpoint in the inward-outward direction of the lateral wall 211, which is formed with a width extending outward from the side surface (base portion 210) of the second side wall 20. The term "approximately midpoint" does not mean a strictly midpoint, but rather includes a position shifted inward or outward from the midpoint in the inward-outward direction of the lateral wall 211.

[0096] In detail, the third protective wall 213 has a roughly L-shaped cross-section, formed by an outer portion of the side wall 211 located on the outer side of the hole (communication hole) and a rib extending upward from the side of the hole (communication hole) within the outer portion of the side wall. The inner surface of the rib is inclined outward as it goes upward. As a result, the card or other object displaying the inserted information is guided along the inclination of the rib to the first receiving portion 330 and the second receiving portion 231. In other words, it is easy to insert the card or other object displaying the information into the first receiving portion 330 and the second receiving portion 231.

[0097] Furthermore, the third protective wall 213 is not limited to having a roughly L-shaped cross-section, but can also be vertically oriented. It may be a wall that extends straight ahead, or it may be a wall that extends in the front-to-back direction (horizontally).

[0098] Furthermore, the first receiving portion 330 may be a through hole 500 without a lower receiving wall 331, as shown in Figure 9. In this case, the information displayed on the information display unit 21 is supported by the lower wall 2310 of the shaft. In other words, the first receiving portion 330 may be designed as a bottomless through hole 500, while the second receiving portion 231 may be designed with a bottom (lower wall 2310 of the shaft).

[0099] Furthermore, the first receiving portion 330 may be designed with a bottom (lower receiving wall 331), while the second receiving portion 231 may be designed without a bottom, i.e., without the lower wall 2310 of the shaft portion. In this case, the information displayed on the information display portion 21 is supported by the lower receiving wall 331.

[0100] Furthermore, both the first receiving section 330 and the second receiving section 231 may be designed to be bottomless. In this case, the information displayed on the information display section 21 may be designed to be supported by the installation surface (ground) on which the container 1 is placed, or by the bottom surface 31 of the container 1.

[0101] (Modification 2) In the embodiment described above, the fixing portion 22 for fixing the locking member 40 is provided on a pair of vertical walls 212, but it is not limited to this configuration. For example, the fixing portion 22 may be provided on a horizontal wall 211 located above the second side wall 20. Alternatively, the fixing portion 22 may be provided below the second side wall 20. When the fixing portion 22 is provided below the second side wall 20, it may be designed to be provided on the third protective wall 213 as described in the modified example 1 above. Furthermore, the fixing portion 22 may be provided on either one of the pair of vertical walls 212. In other words, it is sufficient for the container 1 to have a fixing portion 22.

[0102] (Variation 3) In the embodiments described above, the container 1 is configured to include a second side wall 20 and a second base portion 320, but it is not limited to this configuration. For example, as shown in Figures 10 to 13, the container 100 may include a second side wall 60 and a second base portion 320-1.

[0103] Specifically, as shown in Figure 10, the second side wall 60 includes a shaft portion 23-1 and an inner shaft portion wall 2311-1, which are designed to be longer in the vertical direction than the shaft portion 23 of the second side wall 20. The second base portion 320-1 also includes an inner receiving wall 332-1, which is designed to be longer in the vertical direction than the inner receiving wall 332 of the second base portion 320. Furthermore, the second base portion 320-1 also includes an outer receiving wall 333-1, which is designed to be longer in the vertical direction than the outer receiving wall 333. This allows for an increase in the vertical length of the first receiving portion 330 and the second receiving portion 231.

[0104] Here, as described above, designing the shaft portion 23-1 increases the vertical height of the bearing recess 33. In this case, when the container 100 is assembled, the lower part of the pair of second side walls 60 rests on the second base portion 320-1. Therefore, increasing the vertical height of the bearing recess 33 may necessitate changing the position of the lower side wall 211 upwards.

[0105] However, the container 100 is equipped with an inner wall 2311-1 for the shaft, an inner receiving wall 332-1, and an outer receiving wall 333-1, and is designed so that the vertical length of the first receiving portion 330 and the second receiving portion 231 is increased. Therefore, the information displayed on the information display portion 21 can be received downwards by the vertical length of the first receiving portion 330 and the second receiving portion 231. In other words, the usable range as an information display area can be made wider and more efficient than in the conventional design.

[0106] As described above, this disclosure describes a method in which the height of the second side wall 60 is designed to be short in the vertical direction. This invention is particularly effective when there are limitations on the size of the container 100. This is because, when there are limitations on the size of the container 100, the space available for the information display area of ​​the information display unit 21 is limited.

[0107] As described above, when the container 100 is moved to the folded state, as shown in Figure 11, the first side wall 10 is folded inward first. In Figure 11, for the sake of explanation, the front second side wall 60 is omitted. Also, the left first side wall 10 is in the upright assembled state. After folding the pair of first side walls 10 inward, the pair of second side walls 60 are folded.

[0108] Furthermore, when the pair of first side walls 10 are folded and the pair of second side walls 60 are upright, as shown in Figure 12, the lower ends of the shaft portions 23-1 of the pair of second side walls 60 are located below the outer surface T of the first side wall 10.

[0109] More specifically, the container 100 is configured such that, when the pair of first side walls 10 are folded and the pair of second side walls 60 are upright, the lower ends of the shaft portions 23-1 provided by the pair of second side walls 60 are located below the outer surface T of the first side walls 10.

[0110] Furthermore, the container 100 is configured such that, when the pair of first side walls 10 are folded and the pair of second side walls 60 are upright, the lower end of the bearing recess 33 corresponding to the shaft portion 23-1 is located below the outer surface T of the first side wall 10.

[0111] Furthermore, as shown in Figure 11, 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. Note that the length of the pair of first side walls 10 is not limited to the above.

[0112] For example, the pair of first side walls 10 may be designed so that their length in the left-right direction reaches the center of the bottom surface 31 when folded, or they may be designed so that the pair of first side walls 10 overlap in the vertical direction. In other words, the length of the pair of first side walls 10 may be set appropriately depending on the size and design of the container 1.

[0113] When the container 100 folds the pair of second side walls 60 that are folded later, they come into contact with the pair of first side walls 10 that were folded earlier. Therefore, guide portions 110, as shown in Figures 11 and 13, are provided on the pair of first side walls 10 at the points where the pair of second side walls 60 that are folded later come into contact, so that the pair of second side walls 60 can be folded smoothly.

[0114] The guide portion 110 is positioned horizontally opposite the shaft portion 23-1 of the pair of second side walls 60 when the pair of first side walls 10 are folded and the pair of second side walls 60 are in an upright position. The "portion that the pair of second side walls 60 that are folded later come into contact with" refers, for example, to the outer edges in the width direction of the pair of first side walls 10 (the left and right ends in the front-rear direction shown in Figure 11). More specifically, it is the portion of the outer edges in the width direction of the pair of first side walls 10 after they have been folded that coincides with the rotation range of the shaft portion 23-1 provided on the pair of second side walls 60.

[0115] The guide section 110 is provided with an inclined surface. The inclined surface is sloped away from the outer edges in the width direction of the pair of first side walls 10 after they have been folded, as it extends outward from the outer edges.

[0116] By providing the guide portion 110, when folding the pair of second side walls 60 that are folded later, the shaft portion 23-1 of the second side walls 60 slides against the guide portion 110, guiding the second side walls 60 (or their shaft portion 23-1) upward and in the folding direction, so that the second side walls 60 can be folded relatively smoothly.

[0117] The guide portion 110 is shaped to be inclined by cutting out the outer surface T and the surface in the thickness direction (vertical direction) of the first side wall 10. However, the guide portion 110 is not limited to the above shape and formation position. Furthermore, the guide portion 110 may be provided on the shaft portion 23-1 of the second side wall 60 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 23-1 of the second side wall 60 in a V-shape. In other words, it is sufficient to form something that guides the second side wall 60, which is folded into the container 100 later, upward and in the folding direction.

[0118] (Modification 4) In the embodiments described above, the container 1 is configured to include a second side wall 20, but it is not limited to this configuration. For example, as shown in Figures 14 and 15, the container 200 may also include a second side wall 220.

[0119] Specifically, as shown in Figures 14 and 15, the second side wall 220 is provided with a convex wall portion 221 instead of a convex portion 24. The convex wall portion 221 is an example of a guide portion. Note that the configuration is not limited to having a convex wall portion 221 instead of a convex portion 24; for example, the convex wall portion 221 and the convex portion 24 may each be provided on the second side wall 220.

[0120] As shown in Figures 14 and 15, the convex wall portion 221 comprises a pair of convex horizontal walls 2210 and a convex connecting wall 2211 that connects the outer edges of the pair of convex horizontal walls 2210. The convex wall portion 221 is formed by the pair of convex horizontal walls 2210 and the convex connecting wall 2211, and in a horizontal cross-sectional view when cut horizontally, it is formed in a substantially U-shape. However, the convex wall portion 221 is not limited to a substantially U-shape, and the pair of convex horizontal walls 2210 may be formed in a substantially trapezoidal shape with an inclined surface.

[0121] The convex wall portion 221 extends along the entire vertical length of the information display unit 21. However, the convex wall portion 221 is not limited to extending along the entire vertical length of the information display unit 21; for example, it may be designed to extend to the upper half or the lower half in the vertical direction, in accordance with the shape and size of the second side wall 220.

[0122] Furthermore, multiple convex wall portions 221 are arranged at predetermined intervals in the left-right direction of the information display portion 21. However, the convex wall portions 221 are not limited to being arranged at predetermined intervals; for example, there may be only one convex wall portion 221.

[0123] In this case, as shown in Figure 14, the convex wall portion 221 may be provided so that the base portion 210 is visible, or the convex wall portion 221 may be provided so as to cover the entire surface of the base portion 210 (the entire surface of the information display portion 21). If the convex wall portion 221 is provided so as to cover the entire surface of the base portion 210 (the entire surface of the information display portion 21), the outer surface of the convex connecting wall 2211 may also serve as the information display portion 21. In other words, the convex wall portion 221 may also serve as the base portion 210.

[0124] As shown in Figure 15, the convex side wall 2210 is constructed to be approximately the same length as the side wall 211 in the front-rear direction. However, the convex side wall 2210 may be formed to be shorter or longer than the side wall 211 in the front-rear direction. Furthermore, the convex side wall 2210 only needs to be formed to be located inward from the base outer wall 321, and in the vertical direction, a portion of the convex side wall 2210 may be positioned to overlap with the first receiving portion 330.

[0125] Thus, by having a convex wall portion 221, the second side wall 220 can, for example, when the information displayed in the information display unit 21 is information to be inserted, such as a card, be inserted into the information display unit 21 while guiding it along the convex wall portion 221.

[0126] By inserting a card or the like along the convex wall portion 221, the card or the like with the displayed information can be smoothly guided to the first receiving portion 330 in the insertion direction (up and down direction). Furthermore, the presence of the convex wall portion 221 prevents the card or the like from getting caught on the inner receiving wall 332. Therefore, it is easier to insert cards and the like, and the usable area for displaying information can be widened compared to conventional designs.

[0127] It can also be said that the lower surface of the convex wall portion 221 is composed of the lateral wall 211. The lateral wall end portion 2110 (convex connecting wall 2211) of the lateral wall 211 may be located behind the inner receiving wall 332 of the first receiving portion 330 in the front-rear direction, or it may be located in front of the inner receiving wall 332 of the first receiving portion 330, or it may be on the same plane (flush surface) as the inner receiving wall 332 of the first receiving portion 330.

[0128] (Effects and Benefits) A container (1, 100, 200) according to Embodiment 1 of the present disclosure comprises a bottom wall component 30 having a substantially rectangular bottom surface 31 and base portions (first base portion 310, second base portion 320, 320-1) extending upward from each side of the bottom surface 31, and a pair of first side walls 10 and a pair of second side walls (20, 50, 60, 220) rotatably attached to the bottom wall component 30, wherein the pair of first side walls 10 and the pair of second side walls (20, 50, 60, 220) are assembled in an upright position, and the pair of first side walls 10 and the pair of second side walls (20, 50, 60, 220) are separated, A container (1, 100, 200) that can be displaced into a folded state by folding inward, wherein at least one of the pair of second side walls (20, 50, 60, 220) is provided with an information display section 21 having a base section 210 that can be used as an information display area, a part of the bottom wall component 30 constitutes a first receiving section 330 formed to be able to receive information displayed in the information display section 21, and the first receiving section 330 and the base section 210 are arranged inward from the outer surface of the base outer wall 321, which is the outer wall of the base section (second base section 320, 320-1).

[0129] According to the above configuration, the container (1, 100, 200) is equipped with a first receiving portion 330. The first receiving portion 330 and the base portion 210 are positioned inside the outer surface of the base outer wall 321. In other words, the base outer wall 321, the first receiving portion 330, and the base portion 210 are positioned in that order from the outside of the container (1, 100, 200). The information displayed on the base portion 210 is, for example, information displayed on a card. Therefore, when the second side walls (20, 50, 60, 220) are assembled and the information to be displayed on the information display unit 21 is inserted from the base portion 210 into the first receiving portion 330, the first receiving portion 330 is not covered by the second side walls (20, 50, 60, 220, and the base portion 210), that is, the opening formed above the first receiving portion 330 is not completely blocked, and the information can be inserted up to the first receiving portion 330. In other words, since cards or other items displaying information can be received by the first receiving unit 330, it is possible to realize a container (1, 100, 200) with a wider usable area for information display than conventional containers.

[0130] The container (1, 100, 200) according to Embodiment 2 of the present disclosure may be configured such that, in Embodiment 1 above, the base portion 210 is equipped with guide portions (convex portion 24, inclined portion 240, convex wall portion 221) configured to guide the information displayed on the information display portion 21 along the vertical direction.

[0131] According to the above configuration, the container (1, 100, 200) is equipped with a guide section (convex section 24, inclined section 240, convex wall section 221) on the base section 210. This allows, for example, if the information displayed on the information display section 21 is information to be inserted such as a card, the card to be inserted into the information display section 21 can be inserted while guiding it along the guide section. By inserting the card in this way, the insertion path distance can be increased compared to inserting the card straight in the insertion direction (up and down). Therefore, the usable area for information display can be widened compared to conventional methods.

[0132] The container (1, 100, 200) according to Embodiment 3 of the present disclosure may be configured such that, in Embodiment 1 above, the second side wall (20, 50, 60, 220) comprises a plurality of shaft portions (23, 23-1) configured to be attachable to the bottom wall component 30, the shaft portions (23, 23-1) comprises a second receiving portion 231 formed to be able to receive information displayed on the information display unit 21, and at least one of the plurality of shaft portions (23, 23-1) is located below the information display unit 21.

[0133] According to the above configuration, the second side wall (20, 50, 60, 220) is provided with a plurality of shaft portions (23, 23-1) and a second receiving portion 231. Furthermore, at least one of the plurality of shaft portions (23, 23-1) is positioned below the information display portion 21. By providing the shaft portions (23, 23-1) and the second receiving portion 231 on the second side wall (20, 50, 60, 220), the connection between the second side wall (20, 50, 60, 220) and the second base portion 320 is improved, and the rotational ability is also improved, while providing the second receiving portion 231.

[0134] In the container (1, 100, 200) according to Embodiment 4 of the present disclosure, in Embodiment 1 above, the second side wall (20, 50, 60, 220) is provided with a fixing portion 22 for fixing a locking member 40 that locks information displayed in the information display area, and a part of the locking member 40 may constitute the first receiving portion 330.

[0135] According to the above configuration, the second side walls (20, 50, 60, 220) are provided with fixing parts 22 for fixing the locking members 40 that lock the information displayed in the information display area. Furthermore, a part of the locking member 40 constitutes the first receiving part 330. This makes it possible to fix the information to be displayed on the container (1, 100, 200) to the information display unit 21 while the locking member 40 constitutes a part of the first receiving part 330. In other words, by having the locking member 40 and the first receiving part 330 work together, the information displayed on the information display unit 21 can be protected from the outside.

[0136] The container (1, 100, 200) according to aspect 5 of the present disclosure may be configured such that, in aspect 1 above, the base portion 210 has a convex portion 24 that protrudes outward from the base portion 210 in a cross-sectional view of the vertical section obtained by cutting the base portion 210 vertically.

[0137] According to the above configuration, the container (1, 100, 200) is provided with a convex portion 24 (an example of a guide portion) that protrudes outward from the base portion 210 in a cross-sectional view of the vertical section obtained by cutting the base portion 210 vertically. This allows, for example, when the information displayed in the information display portion 21 is information to be inserted such as a card, the card can be inserted into the information display portion 21 while being bent. By bending the card, the insertion path distance of the card can be increased in the insertion direction (up and down direction) compared to when the card is inserted straight. Therefore, the usable area as an information display area can be widened compared to conventional designs.

[0138] The container (1, 100, 200) according to embodiment 6 of the present disclosure may be configured such that, in embodiment 2 above, the convex portion 24 is provided with an inclined portion 240 in which the amount of outward protrusion increases as it is directed downward in the vertical direction.

[0139] According to the above configuration, the container (1, 100, 200) is equipped with an inclined section 240 (an example of a guide section). As a result, the inserted card or the like, on which the information is displayed, is guided along the inclined section 240 to the first receiving section 330 and the second receiving section 231. In other words, by providing the inclined section 240 This makes it easier to insert cards or other items displaying information into the first receiving section 330 and the second receiving section 231.

[0140] In the container (1, 100, 200) according to Embodiment 7 of the present disclosure, in any one embodiment of Embodiments 1 to 7 above, a part of the base portion (first base portion 310, second base portion 320, 320-1) and a part of the second side wall (20, 50, 60, 220) may constitute the first receiving portion 330.

[0141] According to the above configuration, the container (1, 100, 200) can form a first receiving section 330 with a part of the base section (first base section 310, second base section 320, 320-1) and a part of the second side wall (20, 50, 60, 220). In other words, the first receiving section 330 can be configured to be continuous from the second side wall (20, 50, 60, 220) attached to the base section (first base section 310, second base section 320, 320-1) to the base section (first base section 310, second base section 320, 320-1). This makes it possible to secure an area for inserting cards or the like with information displayed up to the first receiving section 330 formed on the base section (first base section 310, second base section 320, 320-1). Therefore, the usable area for information display can be made wider than in the conventional method.

[0142] [Embodiment 2] Other embodiments of this disclosure are described below. For the sake of convenience, components having the same function as those described in the above embodiments and each of the above modifications are denoted by the same reference numerals, and their descriptions are not repeated.

[0143] (Differences from Embodiment 1) As shown in Figure 16, the second side wall 300 in this embodiment includes a second base portion 320-2. Specifically, the second base portion 320-2 is not provided with the first protective wall 322. In addition, a locking member 40-1 is fixed to the fixing portion 22 of the second side wall 300. The locking member 40-1 is designed such that the downward extension length of the second protective wall 44 is longer than that of the locking member 40.

[0144] (Third receptive area) As described above, the second base portion 320-2 does not have the first protective wall 322, and therefore does not have the outer receiving wall 333 that the first receiving portion 330 has. The second base portion 320-2 has a third receiving portion 330-1. The third receiving portion 330-1 is an example of a "receiving portion" in the present invention.

[0145] As shown in Figure 17, the third receiving section 330-1 is partitioned by a lower receiving wall 331, an inner receiving wall 332, and a second protective wall 44, and is formed to be able to receive information to be displayed on the information display section. That is, the second protective wall 44 may also play the role of the first protective wall 322 (outer receiving wall 333). The third receiving section 330-1 may also include a side wall 211 (side wall end 2110).

[0146] As described above, the third receiving portion 330-1 is composed of a part of the second base portion 320-2 (331, 332, 335), a part of the second side wall 300 (211, 2110), and a part of the locking member 40-1 (second protective wall 44).

[0147] (Arrangement of base, second side wall, and locking member) As shown in Figure 17, in the assembled state, the second side wall 300 is positioned such that the side wall 211 abuts against or is close to the upper part of the second base portion 320-1. More specifically, the side wall 211 is positioned such that it abuts against or is close to the upper base wall 335.

[0148] Furthermore, at least a portion of the third receiving portion 330-1 is positioned on the outer surface of the side wall 211, that is, at a location further outward than the side wall end 2110. For example, in Figure 17, the inner receiving wall 332 constituting the third receiving portion 330-1 is positioned approximately the same as (slightly further back than) the side wall end 2110 in the front-rear direction, but a portion of the lower receiving wall 331 and the second protective wall 44 are positioned further outward than the side wall end 2110.

[0149] Furthermore, it is sufficient that at least a portion of the third receiving portion 330-1 is positioned at a location away from the outside. Therefore, the vertical position of the second protective wall 44, which constitutes a part of the third receiving portion 330-1, is not limited and may be designed appropriately depending on the size, shape, etc., of the second side wall 300. In other words, in Figure 16, the lower end of the second protective wall 44 (base portion 42) may be located above the side wall end portion 2110 (side wall 211).

[0150] For example, in this embodiment, the lower end of the second protective wall 44 extends to the vicinity of the upper end of the foundation outer wall 321, but it is not limited to this. The lower end of the second protective wall 44 may be designed to be at the same height as the foundation upper wall 335 shown in Figure 17, or at the same height as the side wall 211, or the lower end of the second protective wall 44 may be positioned even higher than the side wall 211.

[0151] (Effects and Benefits) According to the above configuration, a portion of the second base portion 320-2 constitutes the third receiving portion 330-1. The container is also capable of transitioning between a folded state and an assembled state. In the assembled state, the side wall 211 abuts against or is close to the upper part of the second base portion 320-2. Furthermore, at least a portion of the third receiving portion 330-1 is positioned at a location further outward than the outer surface (side wall end portion 2110) of the side wall 211.

[0152] In other words, at least a portion of the third receiving section 330-1 is positioned below the side wall 211. This allows information to be inserted into the third receiving section 330-1, which is located below the upper surface of the second base section 320-2, even in a foldable container equipped with a second base section 320-2. Thus, a container with a wider usable area for information display can be realized compared to conventional designs.

[0153] [Embodiment 3] Other embodiments of this disclosure are described below. For the sake of convenience, components having the same function as those described in the above embodiments and each of the above modifications are denoted by the same reference numerals, and their descriptions are not repeated.

[0154] (Differences from Embodiment 1) As shown in Figure 18, the locking member 40-2 is provided with a locking side wall 45 extending inward from the lower end of the locking member 40-2. The locking side wall 45 is provided with locking connecting walls 451 at both ends in the left-right direction of the locking member 40-2. The locking member 40-2 has an insertion hole 452 formed between the rear locking side wall 45 and the front locking side wall 45.

[0155] The insertion hole 452 is a slit-shaped hole partitioned by the locking side wall 45 and the locking connecting wall 451, and communicates with the first receiving section 330 and the second receiving section 231 when the locking member 40-2 is fixed to the fixing section 22. In other words, the information (cards, etc.) displayed on the information display section 21 is inserted into the first receiving section 330 and the second receiving section 231 through the insertion hole 452.

[0156] In other words, as shown in Figures 18 and 19, the locking side wall 45 may constitute part of the first receiving portion 330 and the second receiving portion 231. The rear locking side wall 45 plays the role of the side wall 211. It may also bear the responsibility of dividing the load. In this case, for example, the configuration may include a locking side wall 45 instead of the side wall 211.

[0157] Furthermore, as shown in Figures 18 and 19, the locking member 40-2 may be designed so that the locking side wall 45 is placed above the side wall 211. In addition, the front locking side wall 45 may also serve as the first protective wall 322 (outer receiving wall 333).

[0158] As shown in Figures 18 and 19, the lower end of the locking side wall 45 is positioned in contact with or close to the upper end of the first protective wall 322 (outer receiving wall 333), but it is not limited to this, and may be positioned at a location above the upper end of the first protective wall 322 (outer receiving wall 333).

[0159] (modified version) The locking member 40-2, equipped with a locking side wall 45, can also be applied when the first protective wall 322 is not provided, as in the second side wall 300 described in Embodiment 2. In this case, as in the locking member 40-3 shown in Figure 20, in addition to the locking side wall 45, a fourth protective wall 453 extending downward from the lower end of the locking side wall 45 may be provided.

[0160] As shown in Figure 20, the second base portion 320-2 does not have the first protective wall 322, and therefore does not have the outer receiving wall 333 that the first receiving portion 330 has. The second base portion 320-2 has a third receiving portion 330-1. The third receiving portion 330-1 is an example of a "receiving portion" in the present invention.

[0161] As shown in Figure 20, the third receiving section 330-1 is partitioned by a lower receiving wall 331, an inner receiving wall 332, and a fourth protective wall 453, and is formed to be able to receive information to be displayed on the information display section. That is, the fourth protective wall 453 may also play the role of the first protective wall 322 (outer receiving wall 333). The third receiving section 330-1 may also include a side wall 211 (side wall end 2110).

[0162] The locking side wall 45 may constitute part of the third receiving portion 330-1. The rear locking side wall 45 may also serve the role of the side wall 211. In this case, for example, the configuration may include the locking side wall 45 instead of the side wall 211. Furthermore, as shown in Figure 20, the locking member 40-3 may be designed so that the locking side wall 45 is placed above the side wall 211.

[0163] (Effects and Benefits) According to the above configuration, at least a portion of the locking member 40-2 can function as a protective wall (corresponding to the first protective wall 322). Furthermore, the locking member 40-3 is equipped with a fourth protective wall 453. This allows, for example, when transporting containers lined up adjacent to each other, even if the containers collide with each other, the receiving portion and the card or other object inserted into the receiving portion can be protected from the outside by the locking member 40-2 or the locking member 40-3.

[0164] [Embodiment 4] Other embodiments of this disclosure are described below. For the sake of convenience, components having the same function as those described in the above embodiments and each of the above modifications are denoted by the same reference numerals, and their descriptions are not repeated.

[0165] The embodiments described above are containers (1, 100, 200) comprising a first base portion 310 and a second base portion (320, 320-1, 320-2), with a first side wall 10 and a second side wall (20, 50, 60, 220, 300) rotatably attached to the bottom wall component 30, but are not limited to these.

[0166] For example, the first side wall 10 and the second side walls (20, 50, 60, 220, 300) may not be rotatable and may be fixed to the bottom wall component 30. Alternatively, the first side wall 10 and the second side walls (20, 50, 60, 220, 300) and the bottom wall component 30 may be integrally formed and the container may not rotate. In other words, the container may not be able to change state from an assembled state to a folded state.

[0167] In this case as well, the information display unit 21 equipped with the base unit 210 only needs to be provided on at least one side wall, and the side wall only needs to include a horizontal wall 211 and a fixing unit 22 for fixing locking members (40, 40-1, 40-2, 40-3) that lock the information displayed in the information display area.

[0168] In this embodiment, when the locking members (40, 40-1, 40-2, 40-3) are fixed to the fixing part 22, at least a portion of the inner surfaces of the locking members (40, 40-1, 40-2, 40-3) is positioned on the outer surface of the side wall 211, that is, either in contact with the side wall end 2110 or at a position further outward than the side wall end 2110.

[0169] Furthermore, in this embodiment, the container is provided with a receiving portion between the side wall and the locking members (40, 40-1, 40-2, 40-3) in the inward and outward directions, which is formed to receive information displayed on the information display unit 21, and at least a portion of the receiving portion is positioned on the inward side of at least a portion of the locking members (40, 40-1, 40-2, 40-3).

[0170] Therefore, for example, the vertical position (length) of the second protective wall 44 or the fourth protective wall 453 provided by the locking members (40, 40-1, 40-2, 40-3) is not limited and may be designed appropriately depending on the size and shape of the side wall.

[0171] The locking members (40, 40-1, 40-2, 40-3) are molded from a material that allows for elastic deformation. For example, the locking members (40, 40-1, 40-2, 40-3) are made of a resin such as polypropylene.

[0172] The statement that at least a portion of the inner surface of the locking member (40, 40-1, 40-2, 40-3) is positioned in contact with the side wall end 2110 means, for example, that the locking wall 43 is in contact with the base portion 210, as shown in Figure 16, etc.

[0173] Furthermore, the case is not limited to the case where the locking wall 43 is in contact with the base portion 210, but may also include, for example, the case where the inner surface of the locking side wall 45, the inner surface of the second protective wall 44, or the inner surface of the base portion 42 is in contact with or close to the side wall end portion 2110.

[0174] Even in this case, the inserted information (card, etc.) causes the locking members (40, 40-1, 40-2, 40-3) to elastically deform, or the card, etc., is inserted into the first receiving portion 330 and the third receiving portion 330-1 through a small gap.

[0175] (Effects and Benefits) According to the above configuration, at least a portion of the inner surfaces of the locking members (40, 40-1, 40-2, 40-3) is positioned in contact with the outer surface of the side wall 211 (side wall end 2110), or at a position further outward than the outer surface of the side wall 211 (side wall end 2110).

[0176] Furthermore, according to the above configuration, the container has side walls (first side wall 10 and second side wall) in the inward and outward directions. A receiving portion is provided between one or both of the wall 20 and the locking members (40, 40-1, 40-2, 40-3). Furthermore, at least a portion of the receiving portion is positioned inward from at least a portion of the locking members (40, 40-1, 40-2, 40-3).

[0177] As a result, when the locking member (40, 40-1, 40-2, 40-3) is positioned further outward than the outer surface (side wall end 2110) of the side wall 211, a space is formed between the side wall 211 and the locking member (40, 40-1, 40-2, 40-3) into which information to be displayed in the information display section 21 (for example, a card with information displayed on it) can be inserted. Therefore, by inserting information into this space, information can be inserted vertically to below the side wall 211. Consequently, a container with a wider usable area for information display than conventional containers can be realized.

[0178] Furthermore, if at least a portion of the inner surface of the locking members (40, 40-1, 40-2, 40-3) is positioned in contact with the outer surface (side wall end 2110) of the side wall 211, then information displayed between the side wall 211 and the locking members (40, 40-1, 40-2, 40-3) (for example, a card with information displayed on it) can be sandwiched between the outer surface (side wall end 2110) of the side wall 211 and the inner surfaces of the locking members (40, 40-1, 40-2, 40-3). Thus, a container with a wider usable area for information display than conventional containers can be realized, and information locked to the information display section 21 can be prevented from shifting or coming loose.

[0179] Furthermore, the information (cards, etc.) displayed on the information display unit 21 can pass between the side wall and the locking members (40, 40-1, 40-2, 40-3), and can be inserted into the receiving portion located further inward from the locking members (40, 40-1, 40-2, 40-3). Therefore, at least a portion of the locking members (40, 40-1, 40-2, 40-3) can function as a protective wall (corresponding to the first protective wall 322). For example, when transporting containers lined up next to each other, even if the containers collide with each other, the locking members (40, 40-1, 40-2, 40-3) can protect the receiving portion and the cards, etc. inserted into the receiving portion from the outside.

[0180] This disclosure is not limited to the embodiments described above, 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 invention. [Explanation of symbols]
