Description

  The present invention relates to a folding container used, for example, for storing articles or for sorting.

A folding container has been conventionally used as a container used for transporting articles.
In other words, the folding container can store the article in the assembled state and transport it to the destination by a transportation means such as a truck, and when the article is taken out and emptied at the destination, it is folded into a compact size. Therefore, when recovering an empty container, if it is transported by a transportation means such as a truck in a folded state, there is an advantage that transportation efficiency is increased.

In addition, as this folding container, a folding container in which an opening is formed on one side of the container and a door or a side plate for opening and closing the opening is attached to one side has been proposed (see Patent Documents 1 and 2).
That is, in the case of the folding container as described above, the container is assembled and the article is accommodated, and the door is opened or the side plate is removed and the opening is opened to store the stacked article. Since the container can be taken out from the opening, there is an advantage that it is not necessary to work down the stacked containers one by one. There is also an advantage that such folding containers can be stacked in a store and used as a display shelf.

  However, since not only single items are stored in the container, but also multiple types of items with different shapes and colors may be stored in a stacked state, so it can be used as a display shelf as described above. In this case, when trying to take out the lower product, it is necessary to take out the upper product once, which is very troublesome.

The shelf board 7 is provided with two notches 71 through which the shelf board supporting protrusions 8 can pass at the same interval as the two shelf board supporting protrusions 8 arranged in the horizontal direction at both ends in the longitudinal direction. Can be accommodated in the housing portion 31, the longitudinal dimension is slightly shorter than the inner surface distance of the pair of short side plates 4 facing each other, and the short dimension is one notch 71 than the inner surface distance of the pair of opposing long side plates 5. (See FIG. 8).
In addition, two finger insertion holes 72 are provided in the central portion of the shelf board 7 and are large enough to allow an adult's thumb to pass smoothly.

  Next, the usage method of the folding container 1 comprised in this way is demonstrated.

  First, in the assembled state of the container 1 shown in FIG. 1, after the side plate 6 is placed on the surface of the accommodating portion 31 of the bottom plate 3 (in the one-dot chain line state in FIG. 1), the outer surface side lower portions of the pair of opposing short side plates 4. Is pushed inward, and each short side plate 4 is flipped up with respect to the upper frame 2. At this time, since the lower end surface of the short side plate 4 is located slightly above the surface of the side plate 6 placed on the surface of the accommodating portion 31 of the bottom plate 3, the short side plate 4 is not interfered with the side plate 6. It can be rotated.

  After the short side plate 4 is flipped inward, if the connecting portion of the upper long side plate 51 and the lower long side plate 52 constituting the long side plate 5 is pushed inward, between the upper frame 2 and the bottom plate 3 The upper long side plate 51 and the lower long side plate 52 of each long side plate 5 are bent in a square shape and folded in half. That is, the upper long side plate 51 rotates inward with respect to the long side frame member 22 of the upper frame 2, and the lower long side plate 52 rotates inward with respect to the long side side peripheral portion of the bottom plate 3. The upper long side plate 51 and the lower long side plate 52 which are folded in two on the side plate 6 placed on the receiving portion 31 of the bottom plate 3 are stacked and stored, and further, the upper frame body 2 is mounted on the peripheral portion 32 of the bottom plate 3. Can be folded into a small volume as shown in FIG. At this time, the short side plates 4 are stacked on the long side plate 5 folded in half on the inner side defined by the upper frame body 2.

  On the other hand, when the folding container 1 is used, if the upper frame 2 is grasped and lifted upward from the folded state shown in FIG. 5, the upper long side plate 51 of the long side plate 5 connected to the upper frame 2 is Followed up. The lower long side plate 52 connected to the upper long side plate 51 also extends so as to gradually increase the rotation angle with respect to the upper long side plate 51, and is pulled up following. At this time, since the long side plate 5 supporting the short side plate 4 extends, the short side plate 4 rotates downward under its own weight. Thereafter, when the lower inner surface side of each short side plate 4 is pressed outward, its lower end surface rides on the short side peripheral portion of the bottom plate 3, and the outer surface lower end portion comes into contact with the rising piece 321. Therefore, the inner surface can be erected so as to form a vertical surface. Then, by turning the short side plate 4, the left and right side end surfaces support the inner surface of the long side plate 5 and restrict the bending of the long side plate 5. The fitting ribs 4c of the short side plate 4 are fitted to the fitting ribs 5b formed on the left and right edges of the end edge and the lower long side plate 52, respectively, and the bottom plate 3 In addition to frictional resistance due to the fitting of the lower end surface of the short side plate 4 to the peripheral edge of the short side, the frictional resistance due to the fitting of the fitting rib 4c of the short side plate 4 to the fitting rib 5b of the long side plate 5 is prevented. it can.

  When the container 1 is assembled, if the side plate 6 is inserted along the inner surface of one long side plate 5, its left and right end edges and lower end edge are the engagement projections 4x of the short side plate 4 and the engagement projections 3x of the bottom plate 3. Therefore, the side plate 6 is held in an upright state with the falling of the side plate 6 regulated. Therefore, the opening 5 a of one long side plate 5 can be closed by the side plate 6.

  Therefore, articles can be accommodated inside through the upper opening of the container 1, and the containers 1 containing articles can be stacked and stored or transported (see FIG. 6). At this time, the left and right end surfaces of the side plate 6 are in contact with the inner surface of the short side plate 4, so that the short side plate 4 can be prevented from jumping up. Breakage can be reliably prevented.

  Further, as shown in FIG. 8B, the finger is passed through the finger insertion hole 72 of the shelf 7 in the accommodating portion 31 of the bottom plate 3, and the notch 71 is made to coincide with the shelf support protrusion 8 so that the shelf 7 As shown in FIG. 8 (c), the notch 71 is moved to the shelf after the shelf plate 7 is pulled up above the shelf support projection 8 at the intermediate position. The shelf 7 is slid to one long side plate 5 side so as to be shifted from the plate support projection 8, and the end of the shelf plate 7 is supported from below by the shelf support projection 8. It can arrange | position and can be made to partition the inside of the container 1 in two steps by the shelf board 7. FIG.

  That is, if the inside of the container 1 is divided into two upper and lower stages by the shelf plate 7 as described above, for example, two different types of articles can be transported in a state of being sorted in one container 1.

  On the other hand, if the side plate 6 is pulled up after the article is transported to the destination, the opening 5a of the one long side plate 5 can be opened, and then the opened opening in the state where the containers 1 are stacked. The article can be taken out through 5a (see FIG. 7). In this case, the side plate 6 pulled up along the one long side plate 5 is inserted in the same manner along the inner surface of the other long side plate 5, thereby engaging the engagement projection 3 x of the bottom plate 3 and the engagement projection 4 x of the short side plate 4. Therefore, it is possible to prevent the side plate 6 from being lost. In addition, since the left and right end surfaces of the side plate 6 abut against the inner surface of the short side plate 4 and the short side plate 4 can be prevented from jumping up, it is ensured that the stacked containers 1 collapse due to unintentional jumping of the short side plate 4. Can be prevented.

  When the container 1 is collected after the article has been taken out, a finger is put into the finger insertion hole 72 and the shelf board 7 is lifted up slightly, and the shelf board 7 supported by the shelf board supporting projection 8 is cut out. After sliding 71 so that it comes to the position of the shelf supporting protrusion 8, after passing the shelf supporting protrusion 8 through the notch 71 and dropping into the accommodating portion 31 of the bottom plate 3, as described above, the side plate 6 Is placed on the surface of the accommodating portion 31 of the bottom plate 3, and then the lower portions of the pair of short side plates 4 are pushed inwardly to flip each short side plate 4 up against the upper frame 2, respectively. If the connecting portion of the upper long side plate 51 and the lower long side plate 52 constituting the long side plate 5 is pushed inward, the upper long side plate 51 and the lower side plate 51 of each long side plate 5 are placed between the upper frame 2 and the bottom plate 3. Each side plate 52 is folded into a square shape, folded in half, and stacked on the side plate 6. With the Nera, the upper short side plates 4 are stacked, respectively, and further, can be folded the upper frame 2 are stacked on the peripheral portion 32 of the bottom plate 3 (see FIG. 5).

  Therefore, when recovering the empty container 1, the volume can be reduced and transported, and transport efficiency can be improved.

The folding container concerning this invention is not limited to said embodiment. For example, the side plate 6 may be used also as a shelf plate.
In the embodiment described above, the notches 71 are provided at both ends in the longitudinal direction of the shelf board 7, but one end may be provided.

  In the above embodiment, the shelf supporting protrusions 8 are provided at two places in the height direction of the container 1, but may be one place at an intermediate position or three or more places. In addition, a recess (small projection) is provided on the surface of the shelf support projection that receives the shelf plate, and the recess (small projection) fits into the portion of the shelf plate that can be received by the shelf support projection. And a structure for preventing the shelf board from moving in the horizontal direction may be provided.
