Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a carrying container, and more particularly, to a carrying container in which the contents are easily visible from the outside when the contents are stored inside and stacked in multiple stages. Regarding

[0002]

2. Description of the Related Art A synthetic resin carrying container (container), which is widely used for storing or carrying products such as foods, stores the contents inside and stacks them in multiple stages. , There is a thing that stacks in a tall state (hereinafter referred to as stacking) and, when the inside becomes empty, a stack in a short state (hereinafter referred to as nesting).

This type of transport container is generally called an SN container and has the advantage that it does not contain any contents inside and is not bulky when not in use. By the way, many items such as bread that have been brought into retail stores using containers for transportation are transferred to showcases for display and sale after being brought in. It is widely practiced to set the container for use as it is on a display shelf or the like, and to omit this transfer work to rationalize it.

In the case of a transport container used for such a purpose, when the containers are stacked in multiple stages, the articles (contents) contained therein can be easily visually observed from the outside, and the containers can be accommodated inside the container. It is desired to be able to easily take out the above-mentioned article from the outside and to occupy less empty space when not in use.

Therefore, for example, as shown in FIG. 6, a pair of end wall portions 3 and 4 and a pair of side wall portions 5 and 6 are provided around the bottom plate portion 2.
To form a substantially rectangular container body 1 having an upward opening, and the height of the side wall portions 5 and 6 from the bottom plate portion 2 is determined from the bottom plate portion 2 of the end wall portions 3 and 4. As the height is about half of the height, the inside of the container main body can be visually recognized through the upper side of the short side wall parts 5 and 6 and the container main body located above can be seen when it is empty and not in use. By rotating the container body located 90 ° below with respect to the container body located below, the bottom of the container body located above this can be nested while being inserted into the upper surfaces of the side walls 5 and 6 of the container body located below. A so-called cross type is known (for example, Jitsuko Sho 5
7-57009, etc.).

[0006]

However, as in the above-mentioned conventional example, when one container main body is rotated 90 ° with respect to the other container main body when not in use and stacked on a cross to be in a nesting state, the height direction is increased. Although the space occupied by the container can be reduced, both end portions of the container body located above project from the side wall of the container body located below and the planar occupied space expands rather, and the length of the side wall is particularly long. For a container body that is longer than the length of the part,
There is a problem in that the space occupied by the plane becomes quite large and the effect of increasing the storage efficiency cannot be achieved sufficiently.

In the SN container which is rotated 180 degrees from the stacking state to be in the nesting state, the SN container has a nesting function, so that it is reinforced in a region below about 1/2 of the height of the container body. It is not possible to provide ribs. (If a rib for reinforcement is provided here, this rib interferes and the lower part of the upper container body cannot fit into the upper opening of the upper container body. Therefore, it is the current situation that it is not possible to provide a large opening in the lower part of the container body due to a problem in strength.

In view of the above, it is an object of the present invention to provide a device which has sufficient storage efficiency during nesting and which can improve the internal visibility and the workability of taking out during stacking. And

[0009]

In order to achieve the above object, a carrying container according to the present invention is provided with a pair of end wall portions and a pair of side wall portions which stand upright around a bottom plate portion and which are open upward. A rectangular container body is formed, and a supporting leg portion is provided at a lower portion of an outer surface of each end wall portion, a pocket portion is provided at a position symmetrical to the supporting leg portion at an upper portion of an inner surface, and the side wall portion is provided on an upper portion of each side wall portion. And a side wall reinforcing rib extending downward along the shape of the cut portion is provided on the outer peripheral surface, and the cut portion has a depth that is about half the height of the cut portion and extends over almost the entire width. The flange portion is connected to the upper edges of the wall portion and the side wall portion, and the supporting legs of the upper container body are located on the flange portion of the lower container body when the container bodies are superposed in the same direction,
When stacking in different orientations, the support legs of the upper container body should be immersed in the pockets of the lower container body, and the side wall reinforcing ribs of the upper container body should be immersed in the cutouts of the lower container body. This is a feature, and an opening window may be provided above the side wall reinforcing ribs of the side wall portion.

[0010]

According to the present invention constructed as described above, when stacked in the same direction, the supporting leg portion of the upper container body is positioned on the flange portion of the lower container body to be in a stacking state, and further, the container body. By reinforcing the side wall portion of the container with the side wall reinforcing rib, a deep cut portion can be provided here, and through this cut portion, the product (contained item) stored inside the container body can be visually recognized from the outside and taken out to the outside. it can. Then, when the upper container bodies are overlapped in different directions, that is, the upper container bodies are rotated by 180 °, the supporting leg portion of the upper container body is in the pocket portion of the lower container body and the side wall reinforcing ribs of the upper container body are Nesting is performed by immersing each in the cutout part of the lower container body, which prevents the end of the upper container body from protruding from the side wall part of the lower container body during this nesting, resulting in poor storage efficiency. It can be prevented.

Further, by providing an opening window above the side wall reinforcing rib of the side wall portion, that is, in the lower region of the container body,
The visibility here can be secured.
