  As described above, the solid container Cu positioned above is rotated 180 degrees in a planar manner from the stacking state, and the solid container Cb positioned below and the solid container Cu positioned above are in different directions. In other words, the wide support leg / pocket part S2 of the upper solid container Cu is positioned above the wide pocket / support leg part S1 of the lower solid container Cb and the lower solid container Cb. If the wide pocket / support leg portion S1 of the solid container Cu positioned above is positioned above the wide support leg / pocket portion S2, the wide pocket / support leg portion S1 of the solid container Cb positioned below is widened. The wide support leg c2 of the solid container Cu positioned on the pocket p1 and the wide support leg c2 of the pocket section S2 on the upper side, and the narrow pocket p2 of the wide support leg and pocket section S2 of the solid container Cb positioned on the bottom are located in the pocket p1. The wide pocket of the solid container Cu positioned above and the narrow support leg c1 of the support leg S1 are respectively inserted into the pocket p3 of the short side wall 2c of the solid container Cb positioned below. The support c3 of the short side wall 2d of the solid container Cu positioned at the bottom, and further, the support leg c3 of the short side wall 2c of the solid container Cb positioned above the pocket p3 of the short side wall 2d of the solid container Cb positioned below, Accordingly, approximately half of the upper solid container Cu is fitted and nested in the lower solid container Cb.

  As shown in FIG. 5, in the nesting state, the wide support leg c2 of the solid container Cu positioned on the upper side and the wide support leg c2 of the pocket portion S2 are wide pockets and support legs of the solid container Cb positioned on the lower side. It is inserted into the wide pocket p1 of the part S1, and in this state, the wide support leg of the solid container Cu positioned above and the connecting rib 6 of the wide support leg c2 of the pocket part S2 are wide of the solid container Cb positioned below. It is placed on the bottom p1 ′ of the wide pocket p1 of the pocket / support leg S1. A space portion A existing between the lower solid container Cb and the upper solid container Cu nested in the solid container Cb is formed through the connecting rib 6 of the support leg c2. It communicates with the outside air through the hole 8.

  From such a nesting state, when the upper solid container Cu is pulled upward with respect to the lower solid container Cb, the lower solid container Cb is located between the lower solid container Cb and the upper solid container Cu. Even if the air in the existing space A momentarily becomes a negative pressure state, the outside air instantaneously flows into the space A through the through-holes 8 formed in the connecting rib 6 of the support leg c2, and is positioned below. The negative pressure state of the space A existing between the solid container Cb and the upper solid container Cu is eliminated, so that the upper solid container Cu is smoothly removed from the lower solid container Cb. It is possible to prevent a trouble that the solid container Cb does not come off or the lower solid container Cb is lifted together with the upper solid container Cu.

  As described above, when the outside air flows into the space portion A through the through holes 8 formed in the connection rib 6 of the support leg c2, the middle of the vertical ribs 5 and 5 of the support leg c2 is connected. In order to prevent the intermediate connecting rib 7 from obstructing the flow of the outside air, the intermediate connecting rib 7 is omitted or the length L from the outer wall of the long side wall 2b of the intermediate connecting rib 7 is shortened. You can also.

  Next, another embodiment of the present invention will be described with reference to FIGS.

  This embodiment is located between a pair of pockets p3 formed in the vicinity of the corner of the inner wall of one of the opposing short side walls 2c, 2d and having a depth approximately half that of the solid container C. The short side wall 2c to be expanded is bulged outwardly, and a concave portion 9 extending from the flange 3 of the solid container C to the bottom part p3 ′ or the step part p3 ″ of the pocket p3 is formed on the inner wall 2c ′ of the short side wall 2c. The inner wall 9a of the recess 9 and the inner wall 2c ′ of the short side wall 2c are formed substantially in parallel.

  In this way, when the short side wall 2c located between the pair of pockets p3 of one short side wall 2c is bulged outwardly and the solid container C in which the recess 9 is formed is nested, it is shown in FIG. As described above, the outer wall 2d ′ of the short side wall 2d in which the above-described concave portion of the solid container Cu is not formed and the short side wall 2c in which the concave portion 9 of the solid container Cb is formed below. A space A existing between the solid container Cb positioned below and the solid container Cu positioned above the solid container Cb communicates with the outside air between the inner wall 9a of the recess 9 and the solid container Cb. A gap 10 is formed. Accordingly, when the upper solid container Cu is pulled upward with respect to the lower solid container Cb from such a nesting state, the lower solid container Cb and the upper solid container Cu are separated. Even if the air in the space A existing between them becomes a negative pressure state for a moment, the outside air instantaneously becomes the outer wall 2d ′ of the short side wall 2d of the upper solid container Cu and the lower solid container located below. Cb flows into the space A through the gap 10 formed between the inner wall 9a of the recess 9 and the negative of the space A present between the lower solid container Cb and the upper solid container Cu. The pressure state is eliminated, and therefore, the solid container Cu located above does not come out smoothly, or the solid container Cb located below lifts together with the solid container Cu located above. Can be prevented .

  In the embodiment described above, an example is shown in which the short side wall 2c bulges outward and the recess 9 is formed in the inner wall 2c ′. However, the other short side wall 2d bulges outward and the inner wall A similar recess can be formed in 2d ′. Further, both of the opposing short side walls 2c and 2d may be bulged outward to form a similar recess on both the inner walls 2c'2d '.

  Next, still another embodiment of the present invention will be described with reference to FIGS.

  In this embodiment, the long side wall 2a located between the pocket p1 and the pocket p2 formed on one of the long side walls 2a and 2b facing each other is bulged outwardly to thereby extend the long side wall 2a. The inner wall 2a ′ is formed with a recess 11 extending from the flange 3 of the solid container C to the bottom p1 ′ or step p1 ″ of the pocket p1 and the bottom p2 ′ or step p2 ″ of the pocket p2. In order to form this recess 11 without reducing the width of the flange 3 extending in the outer horizontal direction from the upper end of the long side wall 2a, the inner corner of the solid container C formed by the flange 3 and the long side wall 2a. By inclining the inner wall 11b of the concave portion 11 extending from the portion 12 to the lower end 11a of the concave portion 11 more outward than the inner wall 2a ′ of the long side wall 2a, in other words, by inclining in a more vertical direction, the concave portion 11 is formed. Is formed.

  Conventionally, one short side wall 2c of the solid container Cu positioned above is lifted, or the bottom portion 1 near the short side wall 2d of the solid container Cu positioned above is short of the solid container Cb positioned below. In the state of being placed on the flange 3 on the side wall 2d side, the wide support leg c2 of the wide support leg / pocket portion S2 positioned on the short side wall 2d side of the solid container Cu positioned on the upper side is the length of the solid container Cb positioned below. A so-called slide which is placed on the flange 3 on the side walls 2a and 2b and stacks the upper solid container Cu by sliding the flange 3 on the flange 3 in the direction of the short side wall 2c of the lower solid container Cb. Stacking is taking place. In order to form the concave portion 11 during the slide stacking, if the flange 3 is formed with a narrow width like the concave portion 9 formed in the inner wall 2c ′ of the short side wall 2c described above, when the slide stacking is performed, Since the wide support leg c2 of the upper solid container Cu placed on the flange 3 of the lower solid container Cb and the wide support leg c2 of the pocket portion S2 may come off from the flange 3, the long side wall 2a As described above, the concave portion 11 to be formed needs to be formed without reducing the width of the flange 3.

  In this way, when the long side wall 2a located between the pair of pockets p1 and p2 of one long side wall 2a is bulged outwardly and the solid container C in which the concave portion 11 is formed is nested, it is shown in FIG. As described above, the outer wall 2b ′ of the long side wall 2b where the above-described concave portion of the solid container Cu is not formed and the long side wall 2a where the concave portion 11 of the solid container Cb is formed below. The space A between the inner wall 11b of the recess 11 and the solid container Cb positioned below and the solid container Cu positioned above the solid container Cb is connected to the outside air. A communicating gap 13 is formed. Accordingly, when the upper solid container Cu is pulled upward with respect to the lower solid container Cb from such a nesting state, the lower solid container Cb and the upper solid container Cu are separated. Even if the air in the space portion A existing between them becomes a negative pressure state for a moment, the outside air instantly becomes the outer wall 2b ′ of the long side wall 2b of the upper solid container Cu and the solid container located below. Cb flows into the space A through the gap 13 formed between the inner wall 11b of the recess 11 and the negative of the space A present between the lower solid container Cb and the upper solid container Cu. The pressure state is eliminated, and therefore, the solid container Cu located above does not come out smoothly, or the solid container Cb located below lifts together with the solid container Cu located above. Prevention of occurrence Kill.

  In the embodiment described above, an example is shown in which the long side wall 2a bulges outward and the concave portion 11 is formed in the inner wall 2a '. However, the other long side wall 2b bulges outward and the inner wall A similar recess can be formed in 2b ′. Further, it is also possible to form the same concave portion on both the inner walls 2a'2b 'by expanding both of the opposing long side walls 2a, 2b outward.

  In the present invention, when the upper solid container Cu is pulled upward with respect to the lower solid container Cb from the nesting state, the lower solid container Cb and the upper solid container Cu are Even if the air in the space A existing between them becomes a negative pressure state for a moment, the outside air instantaneously flows into the space A, and the solid container Cb located below and the solid container Cu located above Since it is configured to form a passage (through hole 8, recesses 9, 11) that communicates the space portion A and the outside air so that the negative pressure state of the space portion A existing between them is eliminated, The solid container Cu can be smoothly pulled out from the lower solid container Cb, and the lower solid container Cb is lifted together with the upper solid container Cu. Can be reliably prevented .

  Since the present invention has the configuration as described above, the following effects are achieved.

  The air in the space existing between the lower solid container and the upper solid container when the upper solid container is pulled upward from the lower solid container in the nesting state. However, even if a negative pressure state occurs for a moment, the outside air instantaneously flows into the space portion, and the negative pressure state in the space portion existing between the lower solid container and the upper solid container is eliminated. As described above, it is configured to form a passage that communicates the space and the outside air, so that the upper solid container can be smoothly removed from the lower solid container and the lower container is positioned below. Occurrence of a trouble that the solid container is lifted together with the solid container located above can be surely prevented.

  Since the passage that connects the space and the outside air that exists between the transport container located below and the transport container located above is formed on the support legs, it is necessary to provide the passage without major changes in the mold. Can do.

  Since the passage that communicates the space and the outside air that exists between the transport container located below and the transport container located above is configured as a recess formed in the short side wall, a large passage is formed. Therefore, the solid container located above can be more smoothly pulled out from the solid container located below. Further, since the recess is formed, a step is formed on the short side wall, so that the deformation of the short side wall can be prevented.
