As shown in FIG. 1, the storage tray 1 includes a tray main body 11, a flange portion 12, and a cushioning portion 13. The storage tray 1 stores a single or a plurality of panel-shaped articles in the tray main body 11, and is transported by being stored alone in the outer box or together with another storage tray 1. For example, the storage tray 1 is a tray that can be stacked with other trays, and as a specific example, a straight stacking tray or a 180-degree inverted stacking tray.

Further, the storage tray 1 is formed by molding a sheet material made of a thermoplastic resin material into a mold. As a specific example, the storage tray 1 is formed by vacuum forming a resin sheet such as polypropylene, which is relatively soft and has an elastic force capable of elastically deforming with a predetermined force.

The elastic force that elastically deforms with a predetermined force is such that the panel-shaped article can be supported and the shape of the tray body 11 can be maintained, and the panel-shaped article is formed when an external force is applied to the panel-shaped article. The article may be elastically deformed so as not to be damaged, and the details thereof will be omitted.

Further, the panel-shaped article is a thin plate-shaped article such as a semiconductor wafer or a liquid crystal panel, and may be damaged when an external force such as an impact during transportation is applied. Furthermore, for example, a panel-shaped article is constructed so that the strength in one direction is weaker than the strength in the other direction.

The tray body 11 is formed in a rectangular tray shape having an upper wall portion 21 and a side wall portion 22. The tray body 11 has a single or a plurality of accommodating portions 21a on the upper wall portion 21. The upper wall portion 21 is formed in a rectangular shape, and a side wall portion 22 is integrally provided on the peripheral edge portion.

The accommodating portion 21a is a recess for accommodating a panel-shaped article. The accommodating portion 21a is configured to be able to hold the accommodating panel-shaped article, for example, by having the opening end configured in an undercut shape. A plurality of accommodating portions 21a are provided on the upper surface of the tray main body 11 or a single accommodating portion 21a based on the shape of the panel-shaped article to be accommodating and the tray main body 11. For example, when a plurality of accommodating portions 21a are provided on the upper surface of the tray main body 11, the plurality of accommodating portions 21a are provided on the upper surface of the tray main body 11 so that the directions in which the strength of the panel-shaped article to be accommodated is weak are along the same direction. The accommodating portion 21a may be arranged in the housing portion 21a. The side wall portion 22 is integrally provided on the peripheral edge portion of the upper wall portion 21, in other words, on the edge portion forming the four sides of the side wall portion 22. The side wall portion 22 extends downward from the peripheral edge of the upper wall portion 21.

The flange portion 12 extends along the main surface direction of the upper wall portion 21 of the tray body 11. The flange portion 12 is provided at the lower end of at least one side wall portion 22 of the tray body 11. As a specific example, the flange portion 12 is provided at least at the lower end of the side wall portion 22 of the tray body 11 arranged in a direction in which the strength of the panel-shaped article accommodated in the accommodating portion 21a is weak. The flange portion 12 may be provided at the lower ends of all the side wall portions 22.

The buffer portion 13 is provided integrally with the flange portion 12, respectively. The cushioning portion 13 is provided along the longitudinal direction of the flange portion 12, and is continuous with a protrusion 31 that protrudes upward from the main surface of the flange portion 12 in a mountain shape, and a part of the protrusion 31 and the side wall portion 22. Ribs 32 to be provided. The protrusion 31 is formed by forming a part of the flange portion 12 into a mountain shape from the lower side to the upper side along the longitudinal direction of the side wall portion 22 provided with the flange portion 12.

The rib 32 is provided at one or a plurality of positions in the longitudinal direction of the protrusion 31. In the present embodiment, the ribs 32 are provided at two positions in the longitudinal direction of the protrusion 31. The rib 32 is integrally provided between the protrusion 31 and the side wall portion 22, and is a reinforcing portion that regulates deformation of the protrusion portion 31 with respect to the side wall portion 22 and the flange portion 12.

According to the storage tray 1 configured in this way, an impact is applied to the outer box in which the storage tray 1 is housed by integrally providing the flange portion 12 with a mountain-shaped protrusion 31 extending along the side wall portion 22. When the protrusion 31 is deformed, the impact transmitted when the flange portion 12 and the inner surface of the outer box are buffered can be absorbed. Therefore, it is possible to prevent the panel-shaped article accommodated in the accommodating portion 21a from being damaged due to an impact applied to the tray main body 11.

In particular, since the flange portion 12 and the cushioning portion 13 are provided on the side wall portion 22 in the direction in which the strength against the impact of the panel-shaped article housed in the tray body 11 is weak, at least in the direction in which the strength of the panel-shaped article is weak. , It is possible to prevent the impact from being applied to the panel-shaped article.

Further, by providing the rib 32, the movement of the protrusion 31 in the direction away from the side wall 22 can be restricted. As a result, for example, when an operator who accommodates the storage tray 1 in the outer box holds the flange portion 12 in a state where the panel-shaped article is accommodated in the storage portion 21a during the storage operation, the tray body 11 is moved from the protrusion 31. It is possible to prevent deformation that moves downward at a distance. As a result, when the flange portion 12 is held at one location, the tray body 11 can be prevented from rotating downward and the contained panel-shaped article from falling. The number and arrangement of the ribs 32 can be appropriately set according to the strength between the protrusion 31 and the tray body 11 and the cushioning performance of the cushioning portion 13 to absorb the impact.

Since such a storage tray 1 is provided with a cushioning portion 13 provided on the flange portion 12, the protrusion 31 is deformed to absorb an impact, and the panel-shaped article housed in the storage portion 21a is damaged. Can be prevented. As a result, the storage tray 1 can be stored in the outer box without using a cushioning material or the like, so that the transportation cost can be reduced. Further, since it is not necessary to store the cushioning material or the like in the outer box, by using the storage tray 1, the work of storing and packing the storage tray 1 in the outer box becomes easy, and the work process and the work cost can be reduced. ..

As described above, according to the storage tray 1 according to the embodiment of the present invention, the flange portion 12 provided on the tray main body 11 is provided with the shock absorbing portion 13 that absorbs the impact due to deformation to absorb the impact during transportation. be able to.
