FIG. 8 is a perspective view of the folding container according to the first embodiment of the present invention, and FIG. 9 is a cross-sectional view of the folding container according to the first embodiment of the present invention taken along line B-B in FIG.

  First, the usage method in the state which stood and assembled the folding container 100 is demonstrated.

  As shown in FIGS. 1 and 2, the foldable container 100 has a rectangular parallelepiped box shape as a whole, and can accommodate articles inside (the upper surface of the bottom portion 2). At this time, the pair of first cushioning members 6 is placed in the vicinity of the central portion of the upper surface of the bottom portion 2 while leaving a surplus portion (placed near the top surface end portion of the bottom portion 2). Since the second cushioning material 7 having the same shape as above is attached to the center of the upper surface of the bottom portion 2, the top surface of the bottom portion 2 is provided with a pair of the first cushioning material 6 and the second cushioning material 7. The cushioning material is laid on the entire surface. For this reason, even when an article is accommodated inside the foldable container 100 (the upper surface of the bottom portion 2), it can be appropriately protected from external impacts.

  Next, a method for folding the foldable container 100 will be described.

  As shown in FIGS. 4 and 5, first, the flip-up side wall 5A is rotated upward from the inner side of the foldable container 100 (the flip-up side wall 5A has an upper end on the other side of the upper frame 1). Such an operation is possible because it is pivotally supported by hinges 5a provided on a pair of opposing sides (short sides). In addition, the splash side wall 5A has a hole 5b provided at the lower end thereof fitted into a protruding piece 2a provided in the vicinity of the middle of the short side of the bottom part 2, but the splash side wall 5A has an inner side (from the outside of the folding container 100). If a force to the inward side is applied, the fitting state is eliminated, and the pair of raised side walls 5A can be quickly turned upward.

  As described above, when the flip-up side wall 5A is rotated upward, the first cushioning material 6A is pivotally supported by the hinge 6a provided on the lower end side of the flip-up side wall 5A. In accordance with (in conjunction with) the above operation, it is lifted upward and rotated downward about the hinge 6a.

  At this time, the other side of the first cushioning material 6A (the first cushioning material 6A in the case where the first cushioning material 6A is placed on the upper surface of the bottom portion 2 while the folding container 100 is erected and assembled). The bottom side of the bottom 2 is formed so as to be inclined from one end side of the bottom 2 toward the center of the bottom 2 so that the inclined surface faces downward in a cross-sectional view. The side of the cushioning material 7 on the side of the raised side wall 5A is formed so as to incline from one end side of the bottom 2 toward the center of the bottom 2 so that the inclined surface faces upward in a sectional view. Therefore, the first cushioning material 6A is lifted upward in accordance with (in conjunction with) the operation of the flip-up side wall 5A smoothly without being interfered with the second cushioning material 7 (FIG. 5). ).

  Then, in this state, the flip-up side wall 5B is rotated upward from the inner side of the foldable container 100 in the same procedure as described above (FIG. 6). The other side of the first cushioning material 6B (the bottom portion 2 of the first cushioning material 6B when the first cushioning material 6B is placed on the upper surface of the bottom portion 2 when the folding container 100 is erected and assembled). The one side of the center side is formed so as to be inclined from the other end side of the bottom 2 toward the center of the bottom 2 so that the inclined surface faces downward in a cross-sectional view, whereas the second buffer The side of the material 7 on the side of the raised side wall 5B is formed so as to incline from the other end side of the bottom 2 toward the center of the bottom 2 so that the inclined surface faces upward in a sectional view. The first cushioning material 6B is lifted upward without being interfered with the second cushioning material 7 in accordance with (synchronously with) the operation of the flip-up side wall 5B.

  At this time, it is necessary to rotate the pair of raised side walls 5 to a position horizontal to the bottom 2. That is, as described above, when the folding container 100 is erected and assembled, the pair of raised side walls 5 is folded between the pair of upper side walls 3 and the pair of lower side walls 4 inward of the folding container 100. In order to prevent this, another pair of oppositely facing upper frames 1 is left, leaving a margin (the thickness of the pair of upper side walls 3 and the pair of lower side walls 4) at both ends of the short sides of the upper frame 1 and the bottom 2. Since it is pivotally supported by each side (short side) (it is pivotally supported to interfere with the pair of upper side walls 3 and the pair of lower side walls 4), This is because, if it is rotated, the interference state between the pair of raised side walls 5, the pair of upper side walls 3 and the pair of lower side walls 4 is eliminated, and the foldable container 100 can be smoothly folded. The hinges 5a that pivotally support the pair of raised side walls 5 are provided at positions higher than the hinges 3a that pivotally support the pair of upper side walls 3 (the pair of hinges 3a of the upper frame 1 is provided). While the height of each side (long side) is approximately 4.2 cm, the height of each pair of sides (short sides) provided with the hinge 5a is approximately 2.2 cm), If the flip-up side walls 5 are rotated to a position that is horizontal with respect to the bottom portion 2, the pair of pop-up side walls 5 will not interfere with the movement of the pair of upper side walls 3 and the pair of lower side walls 4.

  Subsequently, while maintaining this state, the pair of upper side walls 3 and the pair of lower side walls 4 are folded inward of the foldable container 100 (FIG. 7). At this time, the pair of upper side walls 3 are pivotally supported by hinges 3 a provided on the pair of opposite sides (long sides) of the upper frame body 1 at the upper end, and the pair of lower side walls 4 One upper end is pivotally supported by a hinge 4a provided on one lower end of the pair of upper side walls 3, and one lower end is supported by a hinge 4b provided on the upper end of each of a pair of opposing sides (long sides) of the bottom 2. If the pair of raised side walls 5 are pivoted to a position that is horizontal with respect to the bottom 2 because they are pivotally supported (interference between the pair of raised side walls 5, the pair of upper side walls 3, and the pair of lower side walls 4). The state in which the state is eliminated), the pair of upper side walls 3 and the pair of lower side walls 4 are naturally folded into the inner side of the foldable container 100 (hinges provided on the lower ends of the pair of upper side walls 3) 4a as fulcrum The center bending state).

  And if a pair of upper side wall 3 and a pair of lower side wall 4 are folded inward of the folding container 100 as it is, a pair of upper side wall 3 and a pair of lower side wall 4 will become the shape which overlaps up and down, and a folding container 100 is in a fully folded state (FIG. 8). At this time, the thickness of the second cushioning material 7 attached to the center of the upper surface of the bottom portion 2 is formed lower than the height of the bottom portion 2 (the thickness of the second cushioning material 7 is approximately 1 cm, The height is approximately 2.5 cm), and the second cushioning material 7 does not become an obstacle when folding the folding container 100 (FIG. 9).

  Finally, a method for assembling the foldable container 100 will be described.

  The foldable container 100 can be assembled by following a procedure reverse to the procedure for folding the foldable container 100 described above.

  That is, first, the upper frame body 1 is lifted to erect the pair of upper side walls 3 and the pair of lower side walls 4. Then, the pair of raised side walls 5 are rotated downward from the inner side of the folding container 100, and a hole 5 b provided in the lower end portion of the pair of raised side walls 5 is provided near the middle of the short side of the bottom portion 2. The projection piece 2a is fitted. As a result, the pair of raised side walls 5 is maintained perpendicular to the bottom 2 and prevents the pair of upper side walls 3 and the pair of lower side walls 4 from being folded inward of the folding container 100. (Because the pair of raised side walls 5 interfere with the pair of upper side walls 3 and the pair of lower side walls 4).

  At this time, the pair of first cushioning members 6 pivotally supported by a hinge 6 a provided on one lower end side of the pair of raised side walls 5 is adapted to the operation of the pair of raised side walls 5 (in conjunction with the bottom portion 2). It is mounted near the upper surface end portion of (Fig. 2).

  Thus, in the present invention, since the second cushioning material 7 having the same shape as that of the margin portion is attached to the central portion of the upper surface of the bottom portion 2, when assembling the foldable container 100, With the first buffer material 6 and the second buffer material 7, the buffer material can be laid on the entire surface of the bottom 2 of the foldable container 100. Therefore, in the present invention, even when an article is accommodated on the entire surface of the bottom portion 2, it can be appropriately protected from an external impact.

  Further, according to the present invention, when the foldable container 100 is folded, the pair of first cushioning materials 6 are lifted upward in accordance with the upward rotation of the pair of flip-up side walls 5. While being attached to the upper surface of the bottom 2, the container can be folded easily and quickly and can be folded compactly.

  Further, according to the present invention, each side of the pair of first cushioning materials 6 on the center side of the bottom portion 2 and both sides of the second cushioning material 7 on the pair of raised side walls 5 do not interfere with each other. Thus, the folding container 100 can be folded smoothly.

  In this embodiment, the overall shape of the foldable container 100 and the members constituting the foldable container 100 (upper frame 1, bottom 2, pair of upper side walls 3, pair of lower side walls 4, pair of raised side walls. 5. The dimensions of the pair of the first cushioning material 6 and the second cushioning material 7) are as described above. However, depending on the type of articles accommodated in the foldable container 100, this may be a different shape or a different dimension. It can also be formed. For example, the overall shape of the foldable container 100 may be a square shape, or the dimensions of each member may be formed larger or smaller.

  In the present embodiment, the other side of the pair of first cushioning members 6 and the two sides of the second cushioning member 7 on the side of the pair of raised side walls 5 are inclined at approximately 70 degrees. However, the pair of first cushioning members 6 can smoothly (in conjunction with) the operation (rotation upward) of the pair of raised side walls 5 without being interfered with the second cushioning member 7. These tilt angles can be formed at other angles as long as they are lifted upward. For example, these inclination angles can be formed at 20 to 80 degrees. In addition, as described above, if it is not considered that the pair of first cushioning materials 6 are lifted smoothly upward, the other side of the pair of first cushioning materials 6 and the second cushioning material. It is also possible to form both sides on the side of the pair of raised side walls 5 perpendicular to the bottom 2 (that is, do not form an inclination).

  Furthermore, in this embodiment, each side of one of the pair of first cushioning members 6 is pivotally supported by a hinge 6a provided on one lower end of the pair of raised side walls 5, and the second cushioning member 7 is attached to the bottom portion 2. The pair of first cushioning material 6 and / or the second cushioning material 7 is detachably attached to the lower end side of the pair of raised side walls 5 and the center of the top surface of the bottom portion 2 respectively. You may comprise.
