[Prior Art]

 Among containers of the same type, as a container capable of stacking and nesting due to the structure of the container itself, for example, a carrying container disclosed in Japanese Utility Model Publication No. 63-40403 is known. This container has a bulging part (pocket part) that bulges outward from the opening edge of the container to the middle height part of the container on the side wall of the rectangular container, and asymmetrically forms the opposite side walls. At the position, nesting, and by rotating either the upper or lower container 180 degrees in the plane direction, the upper and lower containers are configured so that the bulges are staggered and stacking is possible (this stacking method is described below. Is called a 180 degree rotation method).

However, this container has the following problems because the upper container must always be rotated by 180 degrees and placed on the lower container as described above. That is, when a container such as a kanban or a card for displaying the contents is attached to the outside of one side wall of the container, the display device will be in the opposite direction between the upper and lower tiers, and thus, especially in the case of multi-tiered stacking. However, the contents could not be confirmed from one direction, which was inconvenient during storage in a warehouse. In addition, for example, when a container containing contents such as parts is poured into an assembly line, if the containers are stacked in different 180 ° directions for each stage as described above, the containers are placed in order from the top. If they were put down on the line, the orientation of the contents would be different for each container, resulting in poor workability and obstacles to automatic assembly by robots. For this reason, there was a problem that the stacked containers had to be turned and put down on the line, which was troublesome.

On the other hand, in order to solve the above-mentioned problems and improve the handleability thereof, in Japanese Utility Model Laid-Open No. 2-102343, containers are stacked at a normal position, and an upper container is placed on a lower container. A container that can be nested by rotating 180 degrees in a plane direction has been proposed (hereinafter, this stacking method is referred to as same-color stacking).

This container has a supporting leg portion (stacking support portion) protruding from the outer surface of the side wall and protruding from the outer surface of the side wall, and a part of the side wall inflated outward at a point symmetrical position of the side wall of the rectangular container. It is a container for transportation in which a pocket portion (nesting fitting portion) in which the supporting leg portion can be housed is formed.

In general, in a container capable of stacking only, a container having a large plane size (hereinafter referred to as a large box) and a container obtained by equally dividing the plane size of the large box into, for example, one half ( In order to make stacking of two half boxes possible together, the bottom of the big box must be raised and the big box can be stacked on the half box, or the stacking allowance of the big box should be fitted without interference. It is necessary to drop one or both sides of the opening edge (flange) of the half box.

On the other hand, in a container capable of stacking and nesting, stacking a large box and a half box with each other has not been performed regardless of the directionality. Also, between a large box and a half box of a container that enables stacking and nesting and a large box and a half box of the same plane size of a container that can only stack, the large box and the half box are mutually independent regardless of the structure. Stacking is also not implemented. However, it is desired that these containers can be stacked with each other in order to improve the handling efficiency and work efficiency of the containers.

[0008]

[Issues to be solved by the device]

 In order to be able to stack (up and down) each other in a large box and a half box of the same color stacking, it is necessary to install a stacking support part close to the corner of the container. This is because the corner support is most effective in compressive (stacking) strength, and the stacking support is evenly arranged to enable stable stacking.

In the two-half box, it is necessary to have a stacking support part having four or more points support so that the load is more evenly distributed when stacking on the large box. Also, when stacking a large box on a half box, the large box must have at least four points of support, each stack having at least one stacking support section adjacent to each corner.

3 In the case of a rectangular (planar) container, as shown in FIG. 1, the pattern (1) for stacking the half boxes on the big box and the pattern (2) for stacking the big boxes on the half box are as follows: As shown in FIG. 2, there are four types. This is because both the large box and the half box have the same color stacking structure, and the arrangement of the stacking support part and the nesting fitting part has directionality. A and B of the large box 21 and C and D of the half box 22 indicate the directionality, and the arrows indicate the cases where the half box is stacked on the big box and the big box is stacked on the half box, respectively. Therefore, in terms of work efficiency, it is most desirable to use a container that can be reliably stacked in a stable shape without directivity in any of the above patterns.

4 Since the large box and the half box both have the same color stacking structure, a nesting fitting portion for accommodating the stacking support portion is naturally required on the side surface of the container, and the stacking support portion is provided on the nesting fitting portion. The stacking mechanism cannot be fulfilled even when striking.

5 In addition, when a half box is placed on the big box or a big box is piled on the half box at a predetermined position, it is necessary that the piled boxes are stably stacked so as not to shift. I have a problem.

In the case of a large box and a half box that can only be stacked, if the stacking allowance of the large box is pushed in, it is possible to fix the longitudinal box of the large box or the lateral direction of the half box to each other. There is a problem that can not be done. Further, it is necessary that the stacking bin and the half bin that have the same planar size as the stacking bin of the same color and that can be stacked only and that the bin and the half bin can stack on each other between the bins of the same color stacking. The relationship between the stacking support edge and the opening edge becomes a problem.

An object of the present invention is a container for transporting a stacking structure of the same color in which a flat plane having an upward opening is a square, and a large box having a large plane size and a half box having a half plane size thereof are used for load support. On the other hand, it is possible to stack (up and down) each other in a stable manner, and it has excellent compressive strength when stacked in multiple stages, and provides a stackable transport container that can be stacked regardless of direction. It is a thing.

Further, the object of the present invention is a transporting container which can open only upward and has a square flat surface, and is capable of stacking only. The present invention is to provide a container for stacking between a box and a stacking container of the same color, in which a large box and a half box can stack each other in a stable state for load bearing regardless of the box structure and orientation. ..

[0016]

The arrow 23 indicates the arrangement shape (arrangement direction) of the S portion and the N portion by an arrow, and the arrow head is shown from S to N.

The large box and the half box have the above-mentioned features (i), (ii) and (iii), so that the half box can be stacked on the large box regardless of the direction.

(Iv) The opening edge of the long side wall having substantially the same length as the short side wall of the big box in the half box is formed into a shape in which the big boxes can be stacked on the half box and dropped downward by almost the stacking allowance. There is. As a result, when stacking the large boxes on the half boxes, the stacking margin is fitted inside the opposite short side walls of the upper half boxes, straddling the inner long side wall opening edges of the two half boxes arranged side by side. It is possible to stack them by stacking.

(V) Almost downward stacking on the opening edge on the S part of the large box and on the opening edge at the position corresponding to the S part of the half box in the arrangement when stacking the half boxes on the large box. Providing a recessed stacking recess (hereinafter referred to as S part recess or SR part for short), (vi) The opening edge on the S part of the short side wall of the half box is recessed downward by almost the stacking allowance. When stacking, the stacking allowance at the lower part of the upper container fits inside the upper part of the lower container, and the lower end of S part of the upper container becomes By fitting in the concave portion of S, the stacking does not shift or rattle, and more stable stacking is possible. In addition, stacking of large boxes and half boxes is possible without reducing the effective depth.

FIGS. 6 and 7 show examples in which a half box can be stably stacked on a large box regardless of the orientation. The figure is a plan view of the stacking pattern in the case of the large box and the half box having the arrangement shape of the S part and the N part shown in Fig. 3, and S and N of the large box in the figure are the S part and the N part. The placement position is shown, and SR shows the SR part (provided on the S part and at the opening edge other than the S part). In the half box, the opening edge, the N section, the SR section, etc. are omitted, and only the S section is shown by S, and (S) shows the S section of the stacking half box. In addition, the diagonal lines indicate where stacking is supported. According to the figure, the half box 22 can be stacked on the left half of the bin and on the right half without any direction, and the (S) position for supporting stacking is located near each of the four corners. It is understood that they are distributed and stacked in a stable state with good balance for load bearing.

FIGS. 8 and 9 show an example in which a large box can be stacked on a half box and stable stacking can be performed regardless of the directionality. The figure shows the stacking pattern in plan view using the large and half boxes with the arrangement of S and N parts shown in Fig. 3 as an example. The half boxes S, N, and SR in the figure are half boxes, respectively. The arrangement positions of the S portion, N portion, and SR portion of are shown. In the large box, the opening edge, the N portion, the SR portion, etc. are omitted, and only the S portion is indicated by S. (S) shows the S part of the large box that supports stacking. The diagonal lines show the stacking support. According to the figure, the bin 21 can be stacked on the two half-boxes 22 regardless of the direction, and the position (S) that supports the stacking is one point near each of the four corners of the bin. It is understood that they are placed in a well-balanced manner with respect to the load and they are stacked in a stable state.

The same-color stacking transport container according to the present invention, in both cases of stacking a half box on a large box or a large box on the half box, the upper container has each corner part (including the vicinity). ) Is supported by four or more S-sections consisting of at least one S-section, and eventually the load of the upper container is supported by the four corner sections, so stacking is performed in the most stable condition regarding load support. It Moreover, since the S portion is near the corner of the container, the corner portion is reinforced and the most effective corner support in compression (stacking) strength can be achieved. Also, when stacking, the S part of the upper container and the S part of the lower container overlap to support the load comfortably. Also, when stacking, the lower part of the upper container (the stacking fee including the container bottom) fits inside the upper part of the lower container, and the lower end of the S part of the upper container is the S part recess (SR part) of the lower container. ), The stacking becomes stable. Furthermore, by stacking large boxes and half boxes together, stable stacking is possible without reducing the effective depth.

The bins and half-boxes of the transporting container capable of stacking only have (a) substantially the same plane size as the bins and half-boxes of the same color stacking, and (b) the bins of the same-colored stacking on the bin. As in the case of the box, an S-section recess (SR) is provided at the corresponding opening edge, and (c) the opening edge of the long side wall of the half box, which has almost the same length as the short side wall of the large box, is placed below the stacking margin. For the stacking, which is formed into a dropped shape, and (d) near the bottom corners of the large box and the half box, at the position corresponding to the S part end of the large box and the half box of the same color, protruding outward from the side wall. The feature is that a convex portion (hereinafter, convex portion for S) is provided.

Due to the configurations of (a), (b) and (c), the large box and the half box are not only between the transport containers capable of stacking only, but also between the transport containers having the same color stacking. However, regardless of the structure, large boxes can be stacked with each other, half boxes can be stacked with each other, and large boxes and half boxes can be stacked with each other. Further, due to (d), it is possible to lock the long box in the longitudinal direction, or to lock the half box in the lateral direction, so that stacking becomes more stable.

That is, when stacking the half boxes on the big box, the convex portion for S of the half box fits into the concave portion of the S part of the big box to support riding stacking, and when stacking the big boxes on the half box, The center of the bottom of the large box rides on the long side wall opening edge of the half box and the S recess of the half box or the long side wall opening edge enables stable stacking.

Further, in the large box and the half box capable of stacking only, since the convex portion for S and the concave portion for S function correspondingly to the concave portion for S portion and the concave portion for S portion of the container of the same color, only stacking is possible. Even between a container and a container with the same color stacking, a large box and a half box can be stacked with each other, and stable stacking for load bearing is possible. In addition, multi-tiered stacking is possible.
