However, in the former tray 11 having the structure shown in FIG. 5 of the prior art, separate vertical partitions 13 and horizontal partitions 14 are formed on the bottom plate 12. Since the partition is placed on the bottom plate 12 of the tray 11 and the partition is not provided continuously, the holding state of the articles stored in the storage space 15 partitioned by the vertical partition 13 and the horizontal partition 14 becomes unstable. At the same time, it is difficult to take out the articles stored in the storage space 15 from the packaging box B together with the bottom plate 12, and there is a problem that the taking out work becomes complicated.

On the other hand, in the latter Japanese Utility Model Publication No. Hei 5-13705, since a bottom plate (intermediate partition plate) as a tray is provided with a vertical partition and a horizontal partition, it is stored in a storage space. Although the product can be stably held, the bottom plate, the vertical partition and the horizontal partition are all connected to a single punching plate, so it is a storage space that can be made in the same flat area on the tray bottom plate. However, there is a problem that it is difficult to increase the number of sections and adjust the volume in the sections, and it is difficult to deal with the size and weight of the articles to be stored.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and can stably hold stored articles, and increase or decrease the number of partitions and the volume according to the size of the stored articles. The strength of the bottom plate can be adjusted according to the increase or decrease of the weight of the stored articles, and the stored articles can be taken out of the packaging box together with the tray, and the work of taking out is easy. It is intended to provide a partitioned tray.

[0007]

In order to achieve the above object, a tray with a partition according to the present invention is provided with an outer partition which is erected at both edges of a bottom plate via fold lines, and is provided between the outer partitions. A tray made of corrugated cardboard provided with a middle partition which is erected through the fold line on the bottom plate and overlapped with the bottom plate, and fitted into a notch groove provided on the outer edge of the tray and the upper edge of the middle partition. It comprises a plurality of vertical partitions provided in a direction intersecting the outer partition and the middle partition, and a cut or notch is provided at a rising corner of the outer partition and the middle partition of the tray,
A bar is inserted along the direction of the step from the step end of the step on the bottom plate of the tray exposed to the outside partition side when the outer partition and the middle partition are bent by forming the notch or notch. It is characterized by being penetrated.

According to a second aspect of the present invention, the rod-shaped body is made of paper so as to facilitate disposal of a partitioned tray as a packing material after unpacking. It is characterized by being.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION The cuts or cutouts at the rising corners of the outer partition and the inner partition of the corrugated cardboard tray are formed on the substantially fold line between the bottom plate and the outer partition and on the approximately fold line between the bottom plate and the middle partition. Each of the trays is formed in advance in the unfolded state, and generally, a U-shaped notch is provided on the fold line between the bottom plate and the outer partition, and a B-shaped notch is provided on the fold line between the bottom plate and the middle partition. Can be

[0010] The number of bars to be inserted to penetrate the bottom plate of the tray from the end of the step along the direction of the step to reinforce the bottom plate depends on the weight and volume of the articles stored in the tray storage space. The strength of the bottom plate as a tray is adjusted by changing the material of the rod-shaped material to paper, plastic, or metal.

The diameter of the rod-shaped body varies depending on the type of corrugated cardboard step (corrugation of the middle shin) applied to the tray, but the step A has a step height of 4.5 to 4.8 mm (JIS Z 151).
In the case of 6), a rod having a diameter of about 4.2 mm is used.
