[0009] [Embodiment 1] A container 1 according to a first embodiment of the present disclosure will be described in detail below with reference to FIGS. 1 to 6. 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 figure. 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 rectangular 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 that is generally rectangular 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 components] The bottom wall constituent part 30 includes a substantially rectangular bottom surface 31, a pair of first base parts 310 extending upward from each side edge of the bottom surface 31, and a pair of first side walls 10 attached thereto, and a pair of second base parts 320 attached thereto. The pair of first base parts 310 and the pair of second base parts 320 are collectively referred to as base parts 32 extending upward from each side edge of the bottom surface 31 of the bottom wall constituent part 30.

[0012] As shown in Fig. 2, the bottom wall component 30 has a plurality of bearing recesses 33 provided at predetermined intervals in each first base portion 310. Each bearing recess 33 extends in the vertical direction from a position at the same height as the bottom surface 31 to the upper end surface of the first base portion 310. The placement locations and number of bearing recesses 33 may be set appropriately depending on the size of the container 1, the length of the first base portion 310, etc. The bearing recesses 33 receive the shaft portion 10A of the first side wall 10 (see Fig. 1).

[0013] Each second base portion 320 of the bottom wall component 30 is formed with a U-shaped cross section that opens downward (see FIG. 6), and the upper end surface of the second base portion 320 is formed as a substantially horizontal surface, with a pair of wide bearing recesses 33A provided at both longitudinal ends of each second base portion 320. The wide bearing recesses 33A extend a predetermined height upward from a position at the same height as the upper end surface of the second base portion 320 in the vertical direction.

[0014] Furthermore, the upper end surface of the second base portion 320 is slightly higher in the vertical direction than the upper end surface of the first base portion 310 (bearing recess 33 thereof). The upper end surface of the second base portion 320 may be the same height as the upper end surface of the first base portion 310 (bearing recess 33 thereof). The upper end surface of the wide bearing recess 33A is higher in the vertical direction than the upper end surface of the first base portion 310 (bearing recess 33 thereof).

[0015] The height from the upper end surface of the second base portion 320 to the upper end of the wide bearing recess 33A is preferably approximately the same as the width dimension in the front-to-rear direction of the upper end surface of the second base portion 320. The wide bearing recess 33A is designed to be longer in the left-to-right direction than the bearing recess 33. The wide bearing recess 33A receives the shaft portion 23 (see FIG. 3) of the second side wall 20, which will be described later.

[0016] Additionally, a plurality of locking holes 34 are provided at predetermined intervals on the upper end surface of each second base portion 320, penetrating vertically between the wide bearing recesses 33A provided at both ends. Each locking hole 34 is formed in a rectangular shape in plan view that is elongated in the left-right direction. Each locking hole 34 is provided with a first locking stopper 34A that is rectangular in plan view and protrudes a predetermined height upward from the center of the outer side edge of the locking hole 34 to the outer edge of the second base portion 320. Each locking hole 34 is provided with a second locking stopper 34B that is square in plan view and protrudes a predetermined height upward from the center of the inner side edge of the locking hole 34 to the inner edge of the second base portion 320. The location and number of locking holes 34 may be determined appropriately depending on the size of the container 1, the length of the second base portion 320, etc. When the container 1 is in an assembled state, a locking projection 25 (see FIG. 3) of the second side wall 20, which will be described later, fits into the locking hole .

[0017] [First side wall] As shown in Fig. 1, 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 detailed description thereof will be omitted.

[0018] The first side wall 10 is integrally provided with a shaft 10A configured to be rotatable relative to the bottom wall constituent part 30. The shaft 10A has a similar structure to the shaft 23 provided on the second side wall 20 but is narrower in the left-right direction, so a detailed description will be omitted. The first side wall 10 is rotatably attached to each bearing recess 33 of the bottom wall constituent part 30 via the shaft 10A.

[0019] [Second side wall] 3, the second side wall 20 is integrally provided with a pair of shafts 23 configured to be rotatable relative to the bottom wall forming portion 30. The second side wall 20 also has an information display portion 21.

[0020] [Information display section] The information display unit 21 is configured to be usable as an information display area. More specifically, the information display unit 21 is partitioned by 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 area surrounded by the pair of horizontal walls 211, the pair of vertical walls 212, and the flat plate portion 210 is configured to be usable as an information display area.

[0021] The pair of horizontal walls 211 each extend in the left-right direction, and have a width extending outward from the upper and lower edges (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 both vertically aligned edges of the flat plate portion 210. The left-right length of the pair of horizontal walls 211 is formed to be approximately equal to the distance between a pair of wide bearing recesses 33A provided at both ends of the upper end surface of the second base portion 320.

[0022] Of the pair of side walls 211, the lower one is provided on its underside with a pair of locking projections 25 that protrude downward. The pair of locking projections 25 are provided at positions facing the respective locking holes 34 formed in the upper end surface of the second base portion 320 when the pair of second side walls 20 are attached to the bottom wall constituent portion 30 and the pair of second side walls 20 are in an upright state, and are fitted into the respective locking holes 34. This prevents the second side walls 20 from tilting inward when the container 1 is in an assembled state.

[0023] 1 and 3, a pair of recesses 26, which are generally rectangular in front view and recessed to a predetermined depth toward the front, are provided on the lower edge of the rear side surface of the flat plate portion 210 at positions facing the pair of locking protrusions 25. The depth of each recess 26 is set to a depth dimension greater than the protruding height of each second stopper 34B formed on the upper end surface of the second base portion 320.

[0024] 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, contactless tag, smart card, etc.), etc., and is locked to the information display unit 21 by being sandwiched between a locking member 61 described later in [Variation 1] and the flat plate portion 210. The various information may be locked (held) by the locking member 61 alone.

[0025] The information displayed on the information display unit 21 is not limited to information that is locked by the locking member 61 described in [Variant 1] 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.

[0026] 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.

[0027] [Shaft] 3, the second side wall 20 has a pair of shafts 23 configured to be rotatable relative to the bottom wall constituent part 30, which extend downward from the lower side of the second side wall 20 in the horizontal direction (left-right direction) with the information display part 21 (flat plate part 210) sandwiched therebetween. The shafts 23 are rotatably connected to the wide bearing recess 33A of the second base part 320.

[0028] The shaft portion 23 has a pair of engagement protrusions 23A that protrude in the left-right direction from both left-right side surfaces of the lower end portion. The pair of engagement protrusions 23A of each shaft portion 23 is inserted from above into the wide bearing recess 33A of the second base portion 320 and is held rotatably around an axis along the longitudinal direction of the second base portion 320. Therefore, the shaft portion 23 is rotatably connected to the wide bearing recess 33A via the pair of engagement protrusions 23A.

[0029] [Assembly and folding of the container] As described above, the first side wall 10 and the second side wall 20 are rotatably attached to the bottom wall forming part 30 via the respective shafts 10A, 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.

[0030] In embodiment 1, 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 enter the folded state.

[0031] When the pair of second side walls 20 are folded as shown in Fig. 4, the lower edge of the information display unit 21 is positioned outward from the second base portion 320, i.e., the inner edge 320A of the base portion 32, when the container 1 is viewed from above in the folded state as shown in Fig. 5. Specifically, the horizontal wall 211 constituting the lower edge of the information display unit 21 faces the outer edge of the second base portion 320 along the longitudinal direction in the vertical direction. In addition, each second stop 34B protruding upward from the upper end surface of each second base portion 320 is received in each recess 26 of the second side wall 20.

[0032] In addition, in embodiment 1, as shown in Figure 4, when the pair of second side walls 20 are folded, when the container 1 in the folded state is viewed in a plane, the boundary with the horizontal wall 211 and a part of the flat portion 210 face the second base portion 320 in the vertical direction and are located outward from the inner edge 320A of the base portion 32 (see Figure 2).

[0033] 6, the container 1 is assembled by first raising the pair of second side walls 20 in the folded state and then raising the pair of first side walls 10. In this case, the lower lateral wall 211 constituting the information display portion of each second side wall 20 faces the upper end surface of the second base portion 320, and a pair of locking projections 25 (see FIG. 3) protruding downward from the lower surface of the lateral wall 211 are fitted into a pair of locking holes 34 (see FIG. 2) formed in the upper end surface of the second base portion 320.

[0034] [Action and effect] Therefore, the vertical length of information display unit 21 that can be used as an information display area can be increased by the length of the lower edge of information display unit 21 that protrudes outward from second base 320, i.e., from inner edge 320A of base 32. This makes it possible to realize a container with a wider area that can be used as an information display area than conventional containers.

[0035] [Embodiment 2] Next, a container 41 according to a second embodiment will be described with reference to Figures 7 to 9. For ease of explanation, members having the same functions as those described in the container 1 according to the first embodiment will be denoted by the same reference numerals, and the description thereof will not be repeated.

[0036] The container 41 according to the second embodiment has substantially the same configuration as the container 1 according to the first embodiment. However, as shown in Fig. 7, the container 41 has a bottom wall forming part 42 instead of the bottom wall forming part 30. Furthermore, the container 41 has a pair of second side walls 50 instead of the pair of second side walls 20.

[0037] [Extended wall] The configuration of the bottom wall constituent part 42 will be described with reference to Fig. 8. As shown in Fig. 8, the bottom wall constituent part 42 has substantially the same configuration as the bottom wall constituent part 30, except that the pair of second base parts 320 of the bottom wall constituent part 42 do not have the locking hole 34, first retainer 34A, and second retainer 34B on their upper end surfaces. Each second base part 320 also has an extension wall 45 that extends upward across the entire longitudinal width from the outer edge of the upper end surface sandwiched between the pair of wide bearing recesses 33A.

[0038] The height of the extension wall 45 from the upper end surface of the second base portion 320 is set to be slightly lower than the height of the wide bearing recess 33A from the upper end surface of the second base portion 320. The outer surface of each extension wall 45 is formed to be flush with the outer surface of each second base portion 320. Further, at both longitudinal ends of the upper end surface of the second base portion 320 sandwiched between the pair of wide bearing recesses 33A, through holes 46 that are elongated and rectangular in plan view are formed along the inner base end portions of the extension wall 45.

[0039] [Information display section] The configuration of the second side wall 50 will be described with reference to Figures 7 and 9. As shown in Figures 7 and 9, the second side wall 50 has substantially the same configuration as the second side wall 20. However, the second side wall 50 is provided with an information display section 51 that can be used as an information display area, instead of the information display section 21. The information display section 51 has a side wall 511 that protrudes downward and has a U-shaped cross section, instead of the elongated plate-shaped side wall 211 below the information display section 21.

[0040] Therefore, the information display unit 51 is defined by an upper horizontal wall 211 that is long in the left-right direction and has a flat plate shape, a lower horizontal wall 511 that protrudes downward and has a U-shaped cross section, and a pair of vertical walls 212 that extend in the up-down direction and connect both ends of each horizontal wall 211, 511. The inner surfaces of each of the horizontal walls 211, 511 and the pair of vertical walls 212 are connected to the flat plate unit 210.

[0041] Furthermore, a slit 511A is formed at the lower end of the lower lateral wall 511, which protrudes downward with a U-shaped cross section, over almost the entire length in the longitudinal direction. The width of the slit 511A is formed so that, for example, a resin plate such as paper or plastic can be inserted therethrough.

[0042] [Action and effect] The assembled state of the container 41 configured as described above will be described with reference to FIG. 7. As shown in FIG. 7, when the second side wall 50 is in the assembled state, the outer upper edge of the lower lateral wall 511 of the information display unit 51, which can be used as an information display area, is disposed in contact with or in close proximity to the inner upper end surface of the extension wall 45 extending upward from the outer end edge of the second base 320. A gap of a predetermined height is formed between the lower end of the lateral wall 511, which is provided at the lower end edge of the information display unit 51 and protrudes downward in a U-shaped cross section, and the upper end surface of the second base 320. A slit 511A is formed at the lower end along the entire length of the lateral wall 511, which is provided at the lower end edge of the information display unit 51 and protrudes downward in a U-shaped cross section.

[0043] As a result, it becomes possible to insert and arrange a piece of cardboard or a resin plate such as plastic on which information is displayed into the downwardly protruding U-shaped cross-sectional gap formed by the lower lateral wall 511 of the information display unit 51 and the extension wall 45. Furthermore, it becomes possible to insert a piece of cardboard or a resin plate such as plastic on which information is displayed into the slit 511A provided at the lower end of the lower lateral wall 511 of the information display unit 51, thereby preventing the information displayed on the information display unit 51 from being lost during transport of the container 41, for example.

[0044] Furthermore, even if the containers 41 collide with each other when they are transported while arranged adjacent to each other, the lower lateral wall 511 of the second side wall 50 is protected by the extension wall 45. Therefore, it is possible to prevent the information held in the information display unit 51 from falling off or being damaged.

[0045] [Variations] A modification of the above embodiment will be described. In the following description, for the sake of convenience, the same reference numerals will be used to designate components having the same functions as those described in the above embodiment, and the description thereof will not be repeated.

[0046] [Variation 1] 10, of a pair of side walls 211 constituting the information display section 21 of the second side wall 20, the lower side wall 211 may include a fixing portion 211A that fixes a locking member 61 that locks information displayed in the information display area. The locking member 61 and the fixing portion 211A may have corresponding locking structures and fixing structures, respectively, and the locking structures and fixing structures may be formed in any shape.

[0047] 10, protrusions are provided on both ends of the lower side of the locking member 61, and the protrusions are fixed to the fixing portion 211A. In addition, information (paper, a resin plate such as plastic, a sign, a card, etc.) is sandwiched between the locking member 61 and the flat plate portion 210. This allows the information displayed in the information display area to be locked by the locking member 61, and makes it possible to prevent the information displayed on the information display portion 21 from being lost during transportation of the container 1, etc.

[0048] The fixing portion 211A for fixing the locking member 61 may be provided on the horizontal wall 211 located on the upper side. Alternatively, it may be provided on either or both of the pair of vertical walls 212. Examples of the locking member 61 include a card holder and a wireless tag holder. Furthermore, when the extension wall 45 is provided on the second base portion 320 as in [Embodiment 2], the fixing portion 211A may be provided so as to face the extension wall 45 in the front-rear direction when the container is assembled. The extension wall 45 can protect the fixing portion 211A for fixing the locking member 61. Therefore, damage to the fixing portion 211A due to external contact or the like can be prevented. Preferably, the height of the upper end of the extension wall 45 is equal to or greater than the height of the upper end of the fixing portion 211A.

[0049] [Variation 2] A second shaft extending downward from the underside of the second side wall 20 may be provided at a position including the information display area (information display unit 21) in the horizontal direction, and a second bearing recess may be provided in the base 320 corresponding to the second shaft. Furthermore, when the second shaft and second bearing recess are provided, the second shaft may be configured to be disengaged from the second bearing recess (positioned above the second bearing recess) when the pair of second side walls 20 are folded, for example.

[0050] In this case, when the extension wall 45 is provided as in [Embodiment 2], the lower end of the second shaft portion in the detached state is positioned opposite the extension wall 45 in the front-rear direction. Therefore, even when the second shaft portion is detached from the second bearing recess of the second bearing, the second shaft portion can be protected. Therefore, damage to the second shaft portion due to external contact, etc. can be prevented.

[0051] [Additional Notes] 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]
