JP7660875B2 - Lid and container with lid - Google Patents

Description

This disclosure relates to a lid that can be placed over an open-top container and a container with a lid.

Conventionally, this type of lid is known to have a container-side locking hole on the container and a lid-side locking hole into which a locking member is inserted so as to be prevented from coming loose (see, for example, Patent Document 1).

Publication No. 3005198 (Fig. 1, etc.)

In this type of lid and lidded container, if the opposing walls on which the lid locking hole and the container locking hole are provided are separated from each other, there is a concern that the locking member may be easily displaced from the container locking hole when the locking member is inserted into the container locking hole, making the insertion of the locking member difficult. Therefore, there is a need to make it easier to insert the locking member even when the opposing walls on which the lid locking hole and the container locking hole are provided are separated from each other.

A first aspect of the invention made to solve the above-mentioned problems is a lid body that is placed over a container with an open top and has a lid-side locking hole into which a locking member is inserted together with the container-side locking hole of the container to prevent it from coming out, the lid body comprising: a lid-side abutment portion that abuts against the container and keeps the lid-side opposing wall portion in which the lid-side locking hole is formed away from the container-side opposing wall portion in which the container-side locking hole is formed, and an insertion guide portion that protrudes from the opening edge of the lid-side locking hole towards the container-side opposing wall portion and guides the locking member into the container-side locking hole.

A second aspect of the invention is the lid body described in the first aspect, wherein the container-side opposing wall portion protrudes outward from the top opening of the container, the lid-side locking hole and the container-side locking hole are aligned in the vertical direction, and the insertion guide portion extends from the top opening side portion of the opening edge of the lid-side locking hole and is provided with a guide inclined portion that inclines away from the top opening as it extends downward.

A third aspect of the invention is a lidded container having the lid body described in the first or second aspect and the container, wherein the container is a foldable container having, between a bottom wall and an upper frame, a first side wall hingedly connected to the upper frame and the bottom wall so as to be foldable in two, and a second side wall hingedly connected to the upper frame so as to be flipped up and foldable, the locking member has an insertion portion that passes through the lid-side locking hole and the container-side locking hole, and an opposing portion that is disposed at a tip of the insertion portion and passes through the container-side locking hole to face the opening edge of the container-side locking hole from the opposite side to the lid-side locking hole, the container-side locking hole is formed in the upper frame, and the lidded container has a lock accommodating portion between the upper frame and the first side wall or the second side wall located below the lid-side locking hole, in which the insertion portion separated from the locking member is accommodated.

A fourth aspect of the invention is a lidded container as described in the third aspect, in which the lock accommodating portion opens downwardly to eject the insertion portion when the first side wall or the second side wall is rotated so as to be folded against the upper frame.

A fifth aspect of the invention is a lidded container as described in the fourth aspect, in which the lid side locking hole and the container side locking hole are aligned in the vertical direction, the first side wall or the second side wall forms a lower wall of the lock accommodating portion and is provided with an ejection guide wall that slopes downwardly outward, and the inner end of the ejection guide wall is arranged in the same plane as the lower end of the insertion guide portion or further inward of the container than the lower end of the insertion guide portion.

A sixth aspect of the present invention is the container with lid according to the fifth aspect , wherein the discharge guide wall has an upright portion extending vertically upward from an inner end portion.

In the first aspect , an insertion guide portion protrudes from the opening edge of the lid side locking hole in the lid side opposing wall portion, which is held away from the container side opposing wall portion by the lid side abutment portion, toward the container side opposing wall portion, and the locking member inserted into the lid side locking hole is guided by the insertion guide portion to the container side locking hole, making it easy to insert the locking member.

According to the second aspect , the locking member is inserted away from the top opening of the container, i.e., toward the outside of the container, so that the contents of the container are prevented from being damaged.

According to the third aspect , the insertion portion that is detached from the locking member when the lid is removed is accommodated in the lock accommodating portion provided between the upper frame and the first side wall or the second side wall, thereby preventing it from becoming mixed up with the contents of the container.

According to the fourth aspect of the invention, the insertion part is ejected when the container is folded, so that the insertion part can be easily removed.

According to the fifth aspect of the invention, the inner end of the discharge guide wall is arranged in the same plane as the lower end of the insertion guide portion or further inside the container than the lower end of the insertion guide portion, so that the insertion portion that is detached from the locking member is received by the discharge guide wall and prevented from falling inside the container.

According to the sixth aspect , since the discharge guide wall is provided with an upright portion extending vertically upward from the inner end portion, the insertion portion separated from the locking member is further prevented from falling inside the container.

The container with lid 10 of the present disclosure will be described below with reference to Figs. 1 to 21. As shown in Fig. 1, the container with lid 10 is capable of closing the top opening 10B (see Fig. 2) of a folding container 10A (corresponding to the "container" in the claims) with a lid body 30. Both the folding container 10A and the lid body 30 are made of synthetic resin.

As shown in FIG. 2, the folding container 10A of this embodiment has a rectangular shape in plan view and a rectangular parallelepiped shape with an open top. The folding container 10A is configured by assembling a pair of first side walls 13 facing each other in the short side direction and a pair of second side walls 14 facing each other in the long side direction between an upper frame 20 provided at the upper and lower ends and a bottom wall 11, and can be transformed into an assembled state shown in FIG. 2 and a folded state shown in FIG. 3.

As shown in Figures 2 and 4, the bottom wall 11 has an outer edge protruding wall 11A that stands up from the entire outer edge. A pair of locking protrusions 11B that stand up are provided near the outer edge of the short side of the bottom wall 11. Between these locking protrusions 11B and the outer edge protruding wall 11A is an engagement recess 11C that receives the lower end of the second side wall 14. In addition, multiple hinge receiving recesses 11D are formed on the long side of the bottom wall 11.

As shown in Figures 5 and 6, the upper frame 20 has a frame-shaped upper wall 21 (corresponding to the "container-side facing wall" in the claims) and an outer wall 22 that hangs down from almost the entire outer edge of the upper wall 21, and the inside of this upper frame 20 forms the top opening 10B of the folding container 10A. The long side of the upper frame 20 forms a square groove shape with a long side inner wall 23A that hangs down from the inner edge of the upper wall 21. The lower end of the long side inner wall 23A is located slightly above the lower end of the outer wall 22. The outer wall 22 and the long side inner wall 23A are connected by a number of ribs 20L.

The short side of the upper frame 20 has a short side inner wall 23B that protrudes from the inner edge of the upper wall 21. The amount that the short side inner wall 23B protrudes from the upper wall 21 is about 1/4 to 1/6 of the amount that the long side inner wall 23A protrudes from the upper wall 21. The four corners of the upper wall 21 form sunken stacking recesses 21U that engage with stacking protrusions (not shown) formed on the underside of the bottom wall 11 when the folding containers 10A are stacked together.

At both ends of the short side of the upper frame 20, a pivot support portion 25 is formed by bulging the outer wall 22 of the long side of the upper frame 20 inward. The pivot support portion 25 has a first through hole 25A extending in the long side direction for connecting the first side wall 13, and a second through hole 25B extending in the short side direction for connecting the second side wall 14. In addition, a plurality of ribs 20L are provided on the short side of the upper frame 20, which hang down from the upper wall 21, and the hinge receiving portion 20J for connecting the second side wall 14 is also formed on each of the ribs 20L. In addition, a chamfered portion 20M is formed by chamfering the outer corner at the center of the short side of the upper frame 20, which prevents the corner from hitting the hand when the folding container 10A is lifted by gripping the upper frame 20 without the lid 30 attached.

2 and 4, the first side wall 13 is divided into two parts, an upper first side wall 13A and a lower first side wall 13B, at approximately the center in the vertical direction. The upper first side wall 13A and the lower first side wall 13B are rotatably connected to each other via an intermediate hinge portion 13C. In addition, in the first side wall 13, a hinge portion (not shown) provided at the upper end of the upper first side wall 13A is rotatably connected to the first through hole 25A of the upper frame 20, while the hinge portion 13H of the lower first side wall 13B is rotatably connected to the hinge receiving recess 11D of the bottom wall 11. This allows the first side wall 13 to be folded in half starting from approximately the center in the vertical direction.

2 and 3, the second side wall 14 is hinged to the upper frame 20 so as to be rotatable, and can be folded up inward. In detail, as shown in FIG. 7, the second side wall 14 has a main plate 14A, an upper end rib 14B protruding outward from the upper end of the main plate 14A, and an upper protrusion 15 protruding upward from the upper end rib 14B. The upper protrusion 15 is divided into a central upper protrusion 15A arranged in the center of the short side direction, end upper protrusions 15B arranged at both ends, and an intermediate upper protrusion 15C arranged between the central upper protrusion 15A and the end upper protrusion 15B, and a hinge shaft 15J that connects to the second through hole 25B of the upper frame 20 or the hinge receiving portion 20J is provided on the side end surface of each of the upper protrusions 15A to 15C.

In addition, the end upper protrusions 15B and the middle upper protrusions 15C of the upper protrusions 15 have inner walls 15M that extend flush from the main plate 14A of the second side wall 14 (see Figure 8), and the central upper protrusion 15A has an outer wall 15N that stands up from the outer end of the upper end rib 14B (see Figure 7).

When the folding container 10A is in an assembled state, the lower end of the second side wall 14 is received in the engagement recess 11C of the bottom wall 11, and its rotation is restricted by the locking protrusion 11B that abuts it from the inside (see FIG. 2). The second side wall 14 is also sandwiched between the pair of first side walls 13, restricting the first side walls 13 from folding inward.

The folding container 10A can be folded as follows. First, the pair of second side walls 14 are pushed inward strongly to release the engagement between the locking protrusions 11B and the second side walls 14, and the pair of second side walls 14 are then flipped up and folded into the upper frame 20. Next, the pair of first side walls 13 are folded inward in half (see Figure 4). Then, the upper frame 20 overlaps the outer edge protrusion wall 11A of the bottom wall 11, and the folding container 10A enters a folded state (see Figure 3).

To assemble the folding container 10A, the upper frame 20 is lifted upward relative to the bottom wall 11. This causes the upper first side wall 13A and the lower first side wall 13B of the pair of first side walls 13 to open, and the second side wall 14 rotates downward under its own weight and fits between the pair of first side walls 13. When the second side wall 14 is then pressed from the inside to rotate it downward, the locking protrusion 11B of the bottom wall 11 engages with the second side wall 14 to hold the second side wall 14 in an upright position, and the second side wall 14 fits between the first side walls 13 to hold them in an upright position, and the folding container 10A is assembled.

As shown in Figures 9 to 11, the lid body 30 has a top plate 31 and a bank portion 32 that surrounds the top plate 31. The bank portion 32 has an inner wall 32A that stands up from the outer edge of the top plate 31 by about 3 to 4 plate thicknesses, an outer wall 32B that is located at the outer edge of the lid body 30, and an upper wall 33 that connects the inner wall 32A and the outer wall 32B. The upper end of the outer wall 32B is located about 3 to 4 plate thicknesses above the upper end of the inner wall 32A, and the lower end of the outer wall 32B is located about one plate thickness above the lower end of the inner wall 32A.

The upper wall 33 is stepped to connect the outer wall 32B and the inner wall 32A, which are different in height. In detail, the upper wall 33 has an upper upper wall 33A (corresponding to the "lid-side facing wall" in the claims) that protrudes inward from the upper end of the outer wall 32B excluding the four corners of the bank portion 32 to a position closer to the inner wall 32A, a lower upper wall 33B that protrudes outward from the upper end of the inner wall 32A, and a step portion 33C that connects the upper upper wall 33A and the lower upper wall 33B. As shown in FIG. 10, the bank portion 32 is provided with a plurality of bank ribs 32L that connect between the step portion 33C and the outer wall 32B, and the lower end surface of the bank rib 32L is flush with the lower surface of the lower upper wall 33B. The lower upper wall 33B and the bank rib 32L correspond to the "lid-side abutment portion" in the claims. At the four corners of the bank portion 32, the lower upper wall 33B is connected to a position near the upper end of the outer wall 32B (see Figure 9).

As shown in FIG. 11, when the lid body 30 is placed over the folding container 10A, the inner portion of the bank portion 32 of the lid body 30 from the inner wall 32A fits into the top opening 10B of the folding container 10A, and the upper frame 20 of the folding container 10A fits into the portion of the bank portion 32 of the lid body 30 below the lower upper wall 33B. In addition, the lower upper wall 33B and the bank rib 32L abut the upper surface of the upper frame 20, and the upper upper wall 33A is held away from the upper wall 21 of the upper frame 20.

In the lidded container 10 of this embodiment, the locking member 50 allows the lid body 30 to be fixed to the folding container 10A. As shown in FIG. 12, the locking member 50 has a disk-shaped flange portion 51 and an insertion portion 52 that hangs down from the center of the flange portion 51. The insertion portion 52 has a rectangular cross section and an arrow-shaped tip with a return portion 52A (corresponding to the "opposing portion" in the claims) that extends diagonally upward in both directions in the cross section. The upper end surface of the return portion 52A extends horizontally, and the length between both ends is larger than the diameter of the flange portion 51. In addition, a lateral protrusion 52B that protrudes in the cross section longitudinal direction is provided at a position near the flange portion 51 in the insertion portion 52. The upper surface of the lateral protrusion 52B extends horizontally, and the lower surface is inclined so as to approach the insertion portion 52 as it approaches downward. The length between both ends of the lateral protrusion 52B is smaller than the diameter of the flange portion 51.

As shown in Figures 5 and 9, the upper frame 20 and the lid body 30 of the folding container 10A are formed with a container side locking hole 26 (corresponding to the "container side locking hole" in the claims) and a lid side locking hole 36 for inserting the locking member 50 at the center of the short side. The container side locking hole 26 is circular in plan view, and the lid side locking hole 36 is rectangular in plan view. As shown in Figure 13, the longitudinal length of the lid side locking hole 36 is just large enough to receive the insertion portion 52 including the lateral protrusion 52B. In addition, the container side locking hole 26 and the lid side locking hole 36 are smaller than the return portion 52A and the flange portion 51.

The locking member 50 is inserted from above with the lid 30 covering the folding container 10A and the container-side locking hole 26 and the lid-side locking hole 36 aligned vertically. In detail, the longitudinal direction of the lid-side locking hole 36 is aligned with the longitudinal direction of the cross section of the insertion portion 52 of the locking member 50 (the direction in which the return portion 52A protrudes) and the tip of the locking member 50 is placed against the lid-side locking hole 36. When the locking member 50 is pushed in, the return portion 52A elastically deforms as the locking member 50 passes through the container-side locking hole 26 and the lid-side locking hole 36. When the return portion 52A passes through the container side lock hole 26, the return portion 52A elastically returns to its original position, and the upper end surface of the return portion 52A faces the opening edge of the container side lock hole 26, and the flange portion 51 faces (abuts) the opening edge of the lid side lock hole 36, preventing the locking member 50 from coming off and fixing the lid body 30 to the folding container 10A (see Figures 13 and 14). At this time, the flange portion 51 protrudes slightly inward from the upper upper wall 33A. In addition, the side protrusion 52B abuts against the inner surface of the lid side lock hole 36, preventing the locking member 50 from rotating.

To remove the lid body 30, as shown in FIG. 15, the locking member 50 is lifted upward, and the insertion portion 52 between the flange portion 51 and the lateral protrusion portion 52B is cut with a cutter or the like, so that the lid body 30 can be removed from the folding container 10A.

Here, in the lidded container 10 of this embodiment, as shown in FIG. 16, an insertion guide portion 40 is formed near the lid-side locking hole 36 of the lid body 30. The insertion guide portion 40 is disposed next to the top plate 31 side of the lid-side locking hole 36 in the upper wall 33A of the upper stage of the lid body 30. The insertion guide portion 40 includes a guide wall 41 (corresponding to the "guide inclined portion" in the claims) that extends downward from the long side portion of the opening edge of the lid-side locking hole 36 on the top plate 31 side, and a pair of side walls 42 that hang down from the top plate 31 side portion of the short side portion of the opening edge of the lid-side locking hole 36, and the side walls 42 form a block shape that connects the guide wall 41 and the step portion 33C.

As shown in Figures 11 and 16, the guide wall 41 is inclined so that it progresses outward as it extends downward, and its lower end is located near the inner end of the container-side locking hole 26. The lower end surface of the guide wall 41 is located in approximately the same plane as the upper surface of the upper wall 21 of the upper frame 20. In addition, the distance in the inward/outward direction between the outer long side of the opening edge of the lid-side locking hole 36 and the lower end of the guide wall 41 is approximately equal to the width in the short direction of the cross section of the insertion portion 52 of the locking member 50.

As shown in Figures 16 and 17, the outer edge of the side wall 42 extends slightly inward as it extends downward, and the amount of the side wall 42 that protrudes outward from the guide wall 41 increases as it extends upward. Also, as shown in Figures 16 and 18, in the connecting portion between the step portion 33C and the lower upper wall 33B, the portion sandwiched between the pair of side walls 42 is more rounded than the other portions.

As shown in FIG. 11, the folding container 10A has a lock accommodating section 11K formed by bulging the outer surface of the central upper protrusion 15A of the second side wall 14 inward. Specifically, as shown in FIG. 7, the central portion of the central upper protrusion 15A has a discharge guide wall 16 that is inclined so as to approach the inside as it moves upward from the middle of the height direction of the outer wall 15N, and a standing portion 17 that stands upward from the inner end of the discharge guide wall 16. The outer surface of the standing portion 17 is arranged on approximately the same plane as the inner end of the opening edge of the container side lock hole 26, and is arranged inside the lower end of the guide wall 41. The area surrounded by the discharge guide wall 16, the standing portion 17, the outer wall 22, the upper wall 21, and the short side inner wall 23B of the upper frame 20, constitutes the lock accommodating section 11K. The gap between the upper end of the standing portion 17 and the lower end of the short side inner wall 23B of the upper frame 20 is about one plate thickness.

As shown in FIG. 11, when the locking member 50 is inserted into the container side locking hole 26 and the lid side locking hole 36, the lower end of the locking member 50 (the lower end of the insertion portion 52) is positioned about one plate thickness above the upper end of the discharge guide wall 16. Then, when the insertion portion 52 is separated from the locking member 50, the separated insertion portion 52 is guided by the discharge guide wall 16, and the lower end of the insertion portion 52 slides outward, and as shown in FIG. 19, the lower end is located at the corner between the discharge guide wall 16 and the outer wall 22 of the upper frame 20, and the upper end is accommodated in the lock accommodation portion 11K in a state where it is inclined so as to abut against the short side inner wall 23B of the upper frame 20. The insertion portion 52 may be accommodated in the lock accommodation portion 11K in a state where it lies on the outer wall 22 side.

When the second side wall 14 rotates inward in this state, the gap between the ejection guide wall 16 and the outer wall 22 of the upper frame 20 gradually widens, and as shown in FIG. 20, the lock accommodation portion 11K opens downward, and the insertion portion 52 is ejected from the lock accommodation portion 11K (see FIG. 21).

The above is the configuration of the lidded container 10 of this embodiment. Next, the effects of the lidded container 10 will be described. As described above, in the lidded container 10 of this embodiment, the locking member 50 is inserted into the container side locking hole 26 and the lid side locking hole 36, so that the locking member 50 is prevented from coming off and the lid body 30 is fixed to the folding container 10A. Then, the locking member 50 is lifted upward and the insertion portion 52 between the flange portion 51 and the lateral protrusion 52B is cut, so that the lid body 30 can be removed from the folding container 10A.

As described above, in the container with lid 10, the lid body 30 is provided with a bank portion 32 having a bank rib 32L, and the bank rib 32L is configured to abut against the upper surface of the upper frame 20. This reinforces and strengthens the lid body 30, but the upper upper wall 33A including the lid side locking hole 36 is separated from the upper wall 21 of the upper frame 20 including the container side locking hole 26. This raises the concern that when inserting the locking member 50, the tip of the locking member 50 may deviate from the container side locking hole 26, making it difficult to insert the locking member.

In contrast, the lid body 30 of this embodiment is equipped with an insertion guide portion 40 having a guide wall 41 that extends from the opening edge of the lid side locking hole 36 toward the container side locking hole 26, so that by inserting the locking member 50 along this guide wall 41, the locking member 50 is guided into the container side locking hole 26, making it easier to insert the locking member 50. Furthermore, the insertion guide portion 40 also has side walls 42 that sandwich the guide wall 41, which prevents the locking member 50 from shifting laterally.

In addition, the guide wall 41 of the insertion guide section 40 extends outward as it extends downward (i.e., away from the top opening 10B), so that the locking member is inserted toward the outside of the folding container 10A, preventing damage to the contents inside the folding container 10A.

In addition, when lifting the locking member 50 to cut the insertion portion 52, the flange portion 51 of the locking member 50 protrudes slightly inward from the upper wall 33A, making it easier to lift the locking member 50 by hooking the protruding portion on a finger.

When the insertion part 52 is cut off, the insertion part 52 is accommodated in the lock accommodation part 11K, so that the insertion part 52 is prevented from being mixed with the contents in the folding container 10A. Furthermore, since the inner end of the discharge guide wall 16 of the second side wall 14 forming the lower wall of the lock accommodation part 11K is arranged inside the folding container 10A (closer to the top opening 10B) than the lower end of the insertion guide part 40, the insertion part 52 cut off from the lock member 50 is easily received by the discharge guide wall 16, and is prevented from falling into the folding container 10A. Moreover, since the upright part 17 extending vertically upward from the inner end of the discharge guide wall 16 is provided, the insertion part 52 cut off from the lock member 50 is further prevented from falling into the folding container 10A.

In addition, the container side locking hole 26 is small compared to the insertion part 52 that is tilted between the outer wall 22 and the short side inner wall 23B of the upper frame 20 or that lies on the outer wall 22 side, making it difficult to remove the insertion part 52 from the locking accommodation part 11K through the container side locking hole 26. As a result, if, for example, a third party mischievously separates the insertion part 52 from the locking member 50 to open the lid body 30, closes the lid body 30 again, and attaches a different locking member 50, two insertion parts 52 will be ejected from one locking accommodation part 11K, and it will be clear that a third party has opened the lid body 30.

In addition, when the second side wall 14 is rotated inwardly so as to flip up during the process of folding the folding container 10A, the lock accommodating portion 11K opens downward and the insertion portion 52 is ejected from the lock accommodating portion 11K, making it easy to remove the insertion portion 52. Moreover, since the ejection guide wall 16 is inclined downwardly toward the outside, when the second side wall 14 is rotated inward, the lock accommodating portion 11K opens widely and the insertion portion can be easily ejected.

[Other embodiments]
(1) In the above embodiment, the lid-side locking hole 36 and the container-side locking hole 26 are aligned in the vertical direction, but they may be provided in, for example, the outer wall 32B of the lid body 30 and the outer wall 22 of the upper frame 20 and aligned in the inward-outward direction. In this case, the locking member 50 is inserted from the outside.

(2) In the above embodiment, the insertion guide portion 40 is disposed on the inside of the lid-side lock hole 36 in the inward/outward direction of the folding container 10A, but it may be disposed on the outside of the inward/outward direction.

(3) In the above embodiment, the insertion guide portion 40 is block-shaped, but it may be composed of only the guide wall 41.

(4) In the above embodiment, the lid body 30 is placed over the foldable container 10A, but it may be placed over a non-foldable container. The lid body 30 may also be hinged to the container.

(5) In the above embodiment, the locking member 50 was a disposable type that was used by cutting off the insertion portion 52, but it may be a reusable type, such as a padlock.

(6) In the above embodiment, a lock accommodating portion 11K is provided to accommodate the insertion portion 52 that has been separated from the locking member 50. However, the lock accommodating portion 11K may not be provided, and the insertion portion 52 that has been separated from the locking member 50 may fall into or outside the folding container 10A.

(7) In the above embodiment, the lock accommodation portion 11K is configured to open downward when the second side wall 14 is rotated, but it may be configured so that it does not open downward and the insertion portion 52 accumulates.

(8) In the above embodiment, the insertion portion 52 is difficult to remove from the container side locking hole 26. However, the container side locking hole 26 may be enlarged to make it easier to remove the insertion portion 52 from the container side locking hole 26. For example, the container side locking hole 26 may be rectangular or long, small in the short side direction of the container side locking hole 26 and large in the inward and outward directions. The locking member 50, which is prevented from rotating by the opening edge of the lid side locking hole 36, cannot be removed, but when the lid body 30 is removed, the insertion portion 52 can be rotated and removed. Also, the upper end of the separated insertion portion 52 may be configured to protrude from the container side locking hole 26.

(9) The lid-side locking hole 36 and the container-side locking hole 26 may be located on the long side of the lid body 30 and the folding container 10A, i.e., above the first side wall 13.

(10) The inner end of the ejection guide wall 16 may be disposed in the same plane as the lower end of the guide wall 41 of the insertion guide portion 40.

(11) The insertion guide portion 40 (particularly the guide wall 41 and the side wall 42) may be configured so that the lower end is positioned above the upper wall 21 of the upper frame 20.

(12) In the above embodiment, the "container-side facing wall" that is held apart from the "lid-side facing wall" and in which the "container-side locking hole" is formed is the upper wall 21 of the upper frame 20, but it may be some other part. For example, if the container is configured to include a locking part, lever part, handle part, etc., it may be a part of those parts.

(13) An auxiliary member having a through hole smaller than the return portion 52A of the locking member 50 may be disposed below the upper wall 21 of the upper frame 20, and the locking member 50 may be inserted up to the auxiliary member. In this case, the lid side locking hole 36 and the container side locking hole 26 may be larger than the return portion 52A (in this case, the auxiliary member corresponds to the "container side facing wall portion" and the through hole of the auxiliary member corresponds to the "container side locking hole").

(14) The return portion 52A of the inserted locking member 50 may be configured to protrude outward from the folding container 10A, and the flange portion 51 and the return portion 52A may be separated so that only the remaining insertion portion 52 is accommodated in the lock accommodating portion 11K.
