It is a paper tray that becomes a tray shape by connecting side plates together, and the partition part is divided by notches and crease lines on the bottom plate, and the partition is assembled by raising the partition part, and the partition is It is characterized by a structure that does not move relative to the bottom plate.

  The paper tray of the present invention is a paper tray having the above-described configuration, in which a fixed piece is partitioned by a notch and a crease line on the side plate, and the raised partition portion is joined to the fixed piece bent inward. By doing, it can be set as the structure by which the partition is assembled.

  Further, the paper tray of the present invention is partitioned in the paper tray having the above-described configuration so that the two partition portions face each other and their crease lines have a certain distance. It can be set as the structure by which the partition was assembled by joining the partition parts.

  Further, the paper tray of the present invention is a paper tray having the above-described configuration, in which the partition portion is partitioned into a panel portion and a fixed portion whose both ends are longer, and the panel portion is folded in half to form a mountain shape. And it can be set as the structure by which the partition is assembled by joining the both ends of a fixing | fixed part to a baseplate.

  In the paper tray of the present invention, side plates are connected to each of the four sides of a rectangular bottom plate via a crease line, and each side plate is raised with respect to the bottom plate to connect adjacent side plates. A paper tray that is shaped like a partition, and the bottom plate is partitioned by notches and crease lines, and the partition is assembled by raising the partition, and the partition does not move relative to the bottom plate. Since the partition does not tilt or fall even if force is applied in the direction of pushing down, it can be stored stably without shifting in an aligned state, so it is sufficient for conventional plastic trays. Can replace it.
