Lower edges of the partition walls are connected to the bottom plate, and an engagement piece formed on one of the partition walls is engaged with the other partition wall.

In the present invention, since the partition wall is self-supporting on the upper surface of the bottom plate, the side wall can be formed as a single wall. Thereby, since the width | variety of a blank sheet | seat can be made small, the paper removal with respect to a cardboard sheet | seat can be improved. As a result, resources can be used effectively.
Moreover, in this invention, since the operation | work which assembles a partition wall to an outer peripheral wall is lose | eliminated, the tray which has a partition wall can be assembled easily.

An inner wall that overlaps the inner surface of the end wall is connected to the upper edge of the end wall, and a support piece that is bent in the left-right direction is connected to the inner wall. It can be configured to be pushed in the direction.

  In this configuration, when the end wall is raised with respect to the bottom plate, if the overhanging portion is pushed in by the bottom plate and the end wall, the notch on the inner side of the middle folding line of the overhanging portion opens, and the overhanging portion is placed inside the tray. It is bent so as to protrude. As a result, the overhanging portion protrudes into the tray. Further, when the inner wall is overlapped with the inner surface of the end wall, the support piece on the inner wall comes into contact with the protruding portion, and the supporting piece is pushed out into the tray by the protruding portion. Thus, with the above-described configuration, the support piece can be automatically protruded into the tray. And the opening edge part of the package which consists of plastic tray containers can be hooked on the support piece which protruded inside the tray.

  In the tray described above, another support piece bent in the left-right direction is connected to the side portion of the inner wall, and the other support piece is configured to be pushed inward by the inner surface of the side wall. it can.

  In this configuration, when the inner wall is overlapped on the inner surface of the end wall, the other support piece of the inner wall abuts on the inner surface of the side wall, and the other support piece is pushed into the tray by the inner surface of the side wall. In this way, the other support piece can be automatically protruded to the corner of the tray.

In the present invention, since the width of the blank sheet can be reduced, paper removal with respect to the corrugated cardboard sheet can be improved. As a result, resources can be used effectively.
Moreover, in this invention, since the operation | work which assembles a partition wall to a baseplate or an outer peripheral wall is lose | eliminated, the tray which has a partition wall can be assembled easily.
Moreover, in this invention, the intensity | strength and stability of a partition wall are fully securable by connecting the front and back partition walls.

The engaging portion 65 is a rectangular recess formed in the central portion in the left-right direction of the tip edge portion of the rear connecting piece 61B. As shown in FIG. 7B, the engaging portion 65 is engaged with the engaging piece 64 of the front connecting piece 61A.

Next, a procedure for assembling the tray 1 of the present embodiment will be described.
From the state of the blank sheet S (see FIG. 2), the left and right side walls 40, 50 are raised with respect to the bottom plate 10 as shown in FIG. Further, the front and rear end walls 20 and 30 are raised with respect to the bottom plate 10.
At this time, as shown in FIG. 6A, the lower plate 91 and the upper plate 92 of the projecting portion 90 are pushed into the bent line L20 by the bottom plate 10 and the end walls 20 and 30. As a result, the cut on the inner surface side of the middle fold line L20 is opened, the mountain between the lower plate 91 and the upper plate 92 is folded, and the overhanging portion 90 protrudes inward.
In the tray 1 of this embodiment, the direction in which the overhanging portion 90 is bent is guided by forming a cut on the inner surface side of the middle folding line L20 of the overhanging portion 90.

  Subsequently, as shown in FIG. 4, the intermediate wall 70 and the inner wall 80 are bent with respect to the front end wall 20, and the inner wall 80 is overlapped on the inner surface of the front end wall 20. The inner wall 80 is overlapped on the inner surface of the rear end wall 30 by bending 80.

When the inner wall 80 is overlapped on the inner surfaces of the front and rear end walls 20, 30, the first support pieces 81, 81 of the inner wall 80 are pushed inward by the projecting portion 90. Further, the second support pieces 82 and 82 of the inner wall 80 are pushed inward by the inner surfaces of the side walls 40 and 50.
Thereby, the two first support pieces 81, 81 protrude from the central portions of the front and rear inner surfaces of the tray 1, and the second support pieces 82 protrude from the four corners inside the tray 1.

Subsequently, as shown in FIG. 7A, the fingers are hung on the finger hooks 61 and 61 of the front and rear partition walls 60A and 60B, and the front and rear partition walls 60A and 60B are pulled up. Accordingly, the front and rear partition walls 60 </ b> A and 60 </ b> B are separated from the bottom plate 10 and are raised on the upper surface of the bottom plate 10. An opening is formed in the bottom plate 10 at a site where both partition walls 60A and 60B are cut out.
Further, the connecting piece 61A is bent backward with respect to the front partition wall 60A, and the connecting piece 61B is bent forward with respect to the rear partition wall 60B.

  Further, as shown in FIG. 7B, the engaging piece 64 of the front connecting piece 61A is inserted from above into the engaging portion 65 of the rear connecting piece 61B, and the engaging piece 64 is inserted into the engaging portion. Fit to 65. As a result, the engagement piece 64 of the front connection piece 61A enters the lower side of the rear connection piece 61B, and the front edge of the rear connection piece 61B enters the lower side of the front connection piece 61A. In this way, the front and rear partition walls 60A and 60B are connected.

Since the front partition wall 60A is bent rearward with respect to the bottom plate 10, the front partition wall 60A is unlikely to fall backward. Further, since the rear partition wall 60B is bent forward with respect to the bottom plate 10, the rear partition wall 60B is unlikely to fall forward.
Therefore, by connecting the front and rear partition walls 60A and 60B in the front-rear direction, the front and rear partition walls 60A and 60B support each other, so that both the partition walls 60A and 60B are stably self-supporting on the upper surface of the bottom plate 10. Can be made.

And as shown in FIG. 4, the package P is put in the tray 1, the opening edge part of the package P is made into the upper edge part of partition wall 60A, 60B, and each support piece 81,82 (refer FIG. 1). The package P can be accommodated in a suspended state by being hooked on the upper edge.
In the present embodiment, the protrusions 63a and 63b of the partition walls 60A and 60B and the protrusions 81a and 82a of the support pieces 81 and 82 (see FIG. 1) enter the lower surface of the opening edge of the package P. The package P can be stabilized in the tray 1.

  In the tray 1 as described above, as shown in FIG. 1, the front and rear partition walls 60 </ b> A and 60 </ b> B are self-supporting on the upper surface of the bottom plate 10, so that the left and right side walls 40 and 50 can be formed as a single wall. . Thereby, as shown in FIG. 2, since the width | variety of the blank sheet S can be made small and the blank sheet S can be approximated to a rectangle, the paper removal with respect to a cardboard sheet can be improved. As a result, resources can be used effectively.

  Further, in the tray 1, as shown in FIG. 1, since there is no work for assembling the front and rear partition walls 60A and 60B to the outer peripheral wall, the tray 1 having the partition walls 60A and 60B can be easily assembled.

  In the tray 1, the front and rear partition walls 60A and 60B are connected to support the partition walls 60A and 60B. Therefore, the strength of the partition walls 60A and 60B is maintained while the partition walls 60A and 60B are independent. In addition, sufficient stability can be ensured.

  When the tray 1 is assembled, as shown in FIG. 5, when the end walls 20 and 30 are raised with respect to the bottom plate 10, the overhanging portion 90 is pushed inward. Further, as shown in FIG. 3, when the inner wall 80 is overlapped on the inner surfaces of the end walls 20, 30, the first support piece 81 of the inner wall 80 is pushed inward by the projecting portion 90, and the side walls 40, 50 are The second support piece 82 is pushed inward by the inner surface.
