In the conventional trays described above, the outer and inner walls are spaced apart, and the stability of the outer and inner walls is low, so when a load is applied to the outer and inner walls, such as when multiple trays are stacked, , the outer and inner walls may tilt.

An object of the present invention is to provide a tray that can solve the above-mentioned problems and improve the stability of the wall portion.

In order to solve the above problems, the present invention provides a tray including a bottom plate, front and rear end walls raised on the front and rear edges of the bottom plate, and left and right end walls raised on the left and right edges of the bottom plate. and a side wall. The end wall includes an outer wall connected to the edge of the bottom plate, an inner wall connected to the upper edge of the outer wall and folded back toward the inner surface of the outer wall, and an upper edge of the outer wall and the inner wall. and an intermediate plate formed between the upper edge of the holder and the upper edge of the holder. A flap overlapped with the inner surface of the outer wall is connected to the edge of the side wall in the front-rear direction. A support piece protruding toward the outer surface of the inner wall is connected to the left-right edge of the inner wall, and a tip edge of the support piece abuts the flap.

In the tray of the present invention, the supporting pieces connected to the inner wall come into contact with the flaps stacked on the inner surface of the outer wall, thereby regulating the inclination of the end wall in the front-rear direction. Furthermore, the flaps connected to the side wall are sandwiched between the support piece and the outer wall, thereby regulating the inclination of the side wall in the left-right direction. Thus, in the tray of the present invention, the stability of the end walls and side walls can be increased.

Further, in the tray of the present invention, the inner wall and the flap are arranged next to each other in the state of a blank sheet. A support piece is then placed between the inner wall of the blank sheet and the flap. As a result, the support piece does not protrude from the outer edge of the blank sheet, so even if the support piece is formed, the area of the blank sheet can be reduced.

In the tray described above, it is preferable that the support piece is formed in a band shape over the entire edge of the inner wall to improve the stability of the end wall.

In the tray described above, an upper support piece protruding toward the inner surface of the flap is connected to the upper edge of the flap, and the tip edge of the upper support piece is brought into contact with the inner wall so that the end wall May increase stability.
