Detailed Description of the Invention

[0001]

FIELD OF THE INVENTION The present invention relates to a container for carrying articles.

[0002]

2. Description of the Related Art As containers for transporting articles, the containers can be stacked one upon the other when the articles are stored (hereinafter, this stacking method is referred to as "stacking"),
When the items are not stored, place each container on a horizontal surface 180
A structure in which the containers can be fitted together in a nested manner to prevent them from becoming bulky by turning them upside down (hereinafter, this stacking method is referred to as "nesting") is disclosed, for example, in Japanese Utility Model Publication No. 59-737. It is also known in Japanese Utility Model Publication No. 63-40453.

This kind of container is made of a synthetic resin material or the like, and is formed in an inverted truncated pyramid shape in which the bottom area is smaller than the opening area on the entire circumference, and two side walls or four side walls facing each other are formed. In addition, four stacking legs protruding outward from the side wall and four leg insertion recesses that allow each stacking leg to be individually fitted by recessing the inner surface of the side wall outward are provided. It has been done. The stacking leg and the recess for putting in the leg are matched with each other when the containers are vertically stacked in a predetermined direction (the same direction or the opposite direction), but when one container is inverted by 180 ° on the horizontal plane and stacked, all of them are not aligned. Since they are positioned so that they coincide with each other, the nesting and the stacking described above can be selectively used by changing the directionality of the container.

[0004]

Since the stacking legs are provided on the side wall, when stacking the containers containing heavy articles in multiple levels, the lower the container, the lower the load acting on the upper edge of the side wall. Grows larger. Therefore, the side wall of the lower container gradually distorts outward at the part that supports the stacking leg of the upper container, and eventually the stacking leg of the upper container falls into the lower container. Was becoming. As a result, the contents of the lower side container are crushed by the upper side container, and the above phenomenon naturally occurs in the lowermost container in the stacked state, and therefore, the stacked containers are Most of them were to be destroyed, and the damage and danger were so serious.

If the side wall itself is to have strength in order to prevent the above-mentioned problems, the thickness of the side wall must be increased, and the area of the upper edge of the side wall is prevented in order to prevent the side wall from falling. However, if this is done, the outer dimensions of the container will become larger or the internal volume will become smaller. Larger external dimensions will affect the size of containers such as cleaning devices for containers, transport devices, stacker and other operating devices, and storage devices.A smaller internal volume will reduce the amount of stored items. However, it meant that the standard of the contents was changed, and none of them resolved the matter.

The present invention has been made in view of the above circumstances, and even when stacking a large number of articles in a state where a heavy article is stored, the side wall is prevented from being deformed and deformed, and the storage is performed. It is an object of the present invention to provide a transportation container capable of preventing damage to products and collapse of stacked state.

[0007]

In order to achieve the above object, the present invention takes the following technical means. That is, the present invention is an inverted truncated pyramid-shaped transportation container in which the bottom area is smaller than the upper opening area all around, and one of the four corners formed by the crossing of the side walls is interposed. The two corners adjacent to each other are provided with stacking corner legs projecting outward along the outer surface thereof, and the inner surfaces of the two corner corners diagonally located are defined by the inner surfaces thereof. A corner leg receiver is provided that allows the corner leg to be fitted by being recessed outward, and the inner surfaces of the side walls adjacent to both sides of the corner leg are recessed outward. Is provided with a side leg support having a narrow opening in which the corner leg is not fitted, and a step which can be fitted to the side leg support is provided on the outer surface of each side wall adjacent to both sides of the corner leg support. It is characterized by protruding side legs for loading.

[0008]

According to the present invention, since the corner leg and the corner leg support are provided at the corners where the side walls intersect each other, the corner leg and the corner leg support are bent into a corner shape (planar L-shaped bend). Shape)
As a result, strong rigidity is obtained not only in the corner leg and the corner leg receiver but also in the corner portion itself. Moreover, since the load acting on the side wall during stacking is reduced, the load bearing capacity that can be supported can be increased. Since the side leg supports arranged on both sides of the corner leg have a narrow opening, the corner legs do not fall into the side leg supports during stacking or the like.

Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B show a transporting container 1 according to the present invention. FIG. 1A is a plan view, FIG. 1B is a front view, and FIG. 1C is a bottom view. 2 and 3 show a situation in which the containers 1 are stacked, and FIG. 4 shows the lower container 1 in a horizontal plane.
It is a situation where nesting is performed by reversing by 80 °. The side wall 2 on the short side and the side wall 3 on the long side are provided so as to be slightly inclined toward the inner side toward the lower end.
As a whole, it has an inverted truncated pyramid shape in which the bottom area is smaller on the entire circumference than the upper opening area.

Of the four corner portions 4a to 4d formed by intersecting the side walls 2 and 3, two corner portions 4c and 4c adjacent to each other via one side wall 2 on the short side (left side in FIG. 1) and 4d is provided with a corner leg 5 protruding outward so as to form a plane L shape along the outer surface side thereof. These corner legs 5 serve as stacking legs at the time of stacking, and the lower end portions thereof are
It is stopped at a portion slightly above the bottom peripheral portion of the container 1. Reference numeral 7 is a stepped portion that regulates the amount of fitting during nesting.

The corner legs 5 (the corner portion 4 where they are provided)
c, 4d) and the corner portion 4 having a diagonal positional relationship with each other.
The a and 4b are provided with a corner leg support 6 formed by denting the inner surface thereof toward the outside in a plane L shape. The corner leg 5 can be fitted into the corner leg receiver 6 to the position of the step portion 7 at the time of nesting. In order to form the corner leg receiver 6, bulging portions 8 are formed on the outer surfaces of the corner portions 4a and 4b, and the lower surfaces of these bulging portions 8 are at the same level as the step portion 7 described above. It is formed and, like the stepped portion 7, acts to regulate the amount of fitting during nesting.

Side walls 2 and 3 adjacent to both sides of the corner leg 5, respectively.
Is provided with a side leg support 10 formed by denting the inner surface of a portion as close as possible to the corner portions 4c and 4d toward the outside. Each side leg support 10 has a side wall 2,
The width dimension of the corner leg 5 is narrower than the width dimension of the corner leg 5 facing in the same direction. Therefore, the corner leg 5 does not fall into the side leg support 10 by mistake. In order to form the side leg support 10, the side wall 2,
Although the bulging portions 11 are formed on the outer surface of 3, the bulging portions 11 also have the same operation as the step portion 7 and the bulging portion 8 described above.

Side walls 2 adjacent to both sides of the corner leg support 6
A side leg 12 having a shape and a position capable of being fitted to the side leg receiver 10 is projectingly provided at 3. The lower end of the side leg 12 is formed at the same level as the corner leg 5 and serves as a stacking leg when stacking together with the corner leg 5. In order to easily distinguish between stacking and nesting, the side wall 3 on the long side is set as a boundary (see arrow BL) and colored on both sides thereof.
Reference numeral 15 is a reinforcing rib that also serves as a handle, and the widthwise dimension thereof is formed within a range not exceeding a predetermined wall thickness dimension of the side walls 2 and 3. Therefore, both the external dimensions and the internal volume of the container 1
It conforms to the standard value. The lowermost reinforcement rib 15 'of the side wall 2 on the short side is curved downward to facilitate holding the container 1, and a hole 15 "for draining water when cleaning the container 1 is appropriately provided. Has been.

In order to stack the containers 1 thus constructed, the containers 1 are stacked in the same direction as shown in FIG. As a result, the corner leg 5 of the upper container 1 is placed on the upper edges of the corners 4c, 4d of the lower container 1, and the side walls 2, 3 close to the corners 4a, 4b of the lower container 1 are mounted. The side leg 12 of the upper container 1 is placed on the edge portion, and the bottom peripheral portion of the upper container 1 slightly protruding downward from the corner leg 5 or the side leg 12 is fitted into the upper opening of the lower container 1. I will get stuck. As for stacking, as shown in FIG. 3, only the lower end of the short side wall 2 of the upper container 1 is fitted into the upper opening of the lower container 1 in order to speed up the work, and it is slid into a predetermined state. However, even if the corner leg 5 of the upper container 1 passes over the side leg support 10 of the lower container 1 at this time, the corner leg 5 is narrow because the side leg support 10 is narrow. It does not fall into the side leg support 10.

On the other hand, in order to nest the containers 1 with each other, as shown in FIG. 4, one of them (lower side in the drawing)
The container 1 of 1 is turned upside down by 180 ° on the horizontal plane and then stacked. As a result, the corner leg support 6 of the lower container 1
The corner leg 5 of the upper container 1 is fitted into the inside so that the lower surfaces of the stepped portion 7 and the bulging portion 11 are placed on the upper edge peripheral portion of the corner leg receiver 6, and the side leg receiver of the lower container 1 is also received. The side leg 12 of the upper container 1 is fitted in the container 10, and the lower surface of the bulging portion 8 comes to rest on the upper edges of the corners 4c and 4d of the lower container 1.

The corner legs 5 are provided on the adjacent corner portions 4c, 4d via one of the short side walls 2 and the adjacent corner portions 4a, 4a via one of the long side walls 3, respectively. 4d or 4c, 4
It can also be provided in d. In this case, the arrangement of the corner leg support 6, the side leg support 10, and the side leg 12 is naturally changed.

[0017]

According to the present invention, which has the above-described structure, the corner leg and the corner leg support are provided at the corners where the side walls intersect each other. Since the corners themselves also become highly rigid and the load that acts on the side wall during stacking is reduced, the side wall may be distorted outward even when stacking each container containing heavy articles in multiple stages. The stacking legs of the upper container do not fall into the lower container. Therefore, the contents of the lower container are not crushed by the upper container and the stacked state does not collapse.
