[0014]
An object of the present invention is to solve the problems of the above-described conventional transport containers and to provide a transport container capable of smooth slide stacking.
[0015]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention has a wide pocket comprising a combination of a wide pocket and a narrow support leg, a combination of a wide support leg, a wide support leg and a narrow pocket on opposite side walls. Wide stacking legs and pockets are formed, and when stacking, the narrow support legs and wide support legs of the upper container are placed on the flange of the lower container, and When nesting, the narrow support leg of the container positioned above is inserted into the narrow pocket of the container positioned below, and the wide support leg of the container positioned above is positioned below. In the transport container capable of nesting and stacking configured to be inserted into a wide pocket of the container, first, the lower surface of the wide support leg and the wide support leg of the pocket portion and the wide support leg are formed. ~ side A corner formed an outer wall surface of the by the plate-shaped Asked blocks to form with the same width as the width of the lower surface of the wide support leg, and, the gathering block, to the back surface of the bottom from the lower surface of the wide support legs It is configured to extend , and secondly, an inclined surface is formed in front of the sliding block in the sliding direction.
[0016]
【Example】
Hereinafter, examples of the present invention will be described with reference to FIGS. 1 to 4, but the present invention is not limited to these examples as long as the gist of the present invention is not exceeded. In addition, since it is the same as that of the conventional conveyance container mentioned above about components other than the approaching ribs c1a and c2a, while using the same code | symbol about the same component, the description is abbreviate | omitted.
[0017]
In the present invention, the shape of the supporting rib c2a formed on the support leg c2 of the wide support leg / pocket portion S2 in the example shown in FIG. It is a thing.
[0018]
Instead of the above-mentioned conventional approaching rib c2a, the width of the lower surface c2 ′ of the support leg c2 (in the corner formed by the lower surface c2 ′ of the support leg c2 of the wide support leg / pocket portion S2 and the outer wall surface 2a of the long side wall 2) A plate-like approach block 6 having substantially the same width as the length w1 of the long side wall 2 along the outer wall surface 2a and extending from the lower surface c2 'of the support leg c2 to the back surface 1a of the bottom 1 is formed. Has been. Moreover, the inclined surface 6b is formed in the corner | angular part formed by the side wall located in the slide direction front of the approach block 6, and the front surface 6a. In addition, 6c is a recessed part formed in the approach block 6 for weight reduction of a container.
[0019]
Since the plate-like shift block 6 having substantially the same width w1 as the lower surface c2 ′ of the support leg c2 is formed on the support leg c2 as described above, it is positioned upward during the slide stacking slide shown in FIG. The support leg c2 of the wide support leg / pocket part S2 of the container Ba to be formed is formed on the long side wall 2 of the container Ba positioned above when passing through the pocket p2 of the wide support leg / pocket part S2 of the container Bb positioned below. The support block 6 of the support leg c2 of the wide support leg / pocket part S2 becomes difficult to enter the pocket p2 of the wide support leg / pocket part S2 of the container Bb positioned below, and therefore smooth slide stacking becomes possible. Further, since the inclined surface 6b is formed in front of the sliding direction, the shifting block 6 includes an inner side surface p2a positioned on the side of the support leg c2 of the pocket p2 of the container Bb positioned below, and an inner wall surface 2b of the long side wall 2; Even if it abuts on the corner portion 7 formed by the above-mentioned, the slide rib c2a abuts on the inner side surface p2a located on the side of the support leg c2 of the pocket p2 of the container Bb located below and slides like the conventional container. Stacking is not prevented, and the support leg c2 can be easily advanced along the inclined surface 6b, so that smoother slide stacking is possible.
[0020]
The narrow support leg c1 of the wide pocket / support leg part S1 can also be formed with a plate-like approach block 8 having substantially the same width w2 as the lower surface c1 'of the same support leg c1, and the sliding direction of the approach block 8 An inclined surface 8a can be formed forward. The vicinity of the end of the bottom 1 of the container Ba positioned on the upper side is placed on the short side wall 3 positioned on the wide support leg / pocket S2 side of the container Bb positioned on the lower side, and the wide pocket of the container Ba positioned on the upper side. -After placing the support leg c1 of the support leg S1 on the flange 4 positioned above the wide support leg c2 of the container Bb positioned below and the wide support leg c2 of the pocket S2, the container Ba positioned above is When the container Bb is slid in the direction of the short side wall 3 located on the side of the wide pocket / support leg part S1 (leftward in FIG. 4), the support leg of the wide pocket / support leg part S1 of the container Ba located above c1 passes through the pocket p2 of the wide support leg / pocket portion S2 of the container Bb positioned below, but the plate-like approach block 8 having substantially the same width w2 as the lower surface c1 ′ of the support leg c1 is provided on the support leg c1. Forming This makes it difficult for the shift block 8 of the support leg c1 of the wide pocket / support leg S1 formed in the long side wall 2 of the container Ba located above to enter the pocket p2 of the wide support leg / pocket part S2 of the container Bb positioned below. Therefore, smooth slide stacking becomes possible. In addition, since the inclined surface 8a is formed in front of the sliding direction, the shifting block 8 has a longer length than the wide side pocket p2 of the container Bb and the inner side surface p2a positioned on the side of the support leg c1 of the support leg S1. Even if it abuts against the corner portion 9 formed by the inner wall surface 2b of the side wall 2, the support leg c1 can easily advance along the inclined surface 8a, so that slide stacking is prevented as in the case of a conventional container. This makes it possible to perform smoother stack stacking.
[0021]
In the above-described embodiment, an example in which the wide pocket / support leg portion S1 and the wide support leg / pocket portion S2 are disposed on the opposed long side walls 2 is shown. A support leg S1 and a wide support leg / pocket part S2 may be provided. Also in this case, a support block having an inclined surface in the forward direction in the same sliding direction as described above can be formed on the support leg so that slide stacking along the short side wall 3 can be easily performed.
[0022]
【The invention's effect】
Since the present invention has the configuration as described above, the following effects are achieved.
[0023]
Since the shift block having substantially the same width as the lower surface is formed on the lower surface of the support leg, the slide stacking is not prevented as in the case of the conventional transport container, and smooth slide stacking is possible.
[0024]
Since the inclined surface is formed in front of the sliding block in the sliding direction, smoother stacking is possible.
