However, in the case of the panel transport container shown in Patent Document 1 described above, since the panel holding portion has cushioning properties, the contact mark is in contact with the portion of the panel holding portion where the panel contacts (that is, the protruding end of the panel support portion). There was a problem that left.
Moreover, in patent document 2, after storing a panel, it is the structure which puts air in an airbag and closely_contact | adheres to a panel, but since the operation | work which puts air in an airbag after accommodating a panel in a container main body is needed. In addition, the structure of the container becomes complicated and the storing operation becomes complicated, so there is room for improvement in that respect.

  The present invention has been made in view of the above-described problems, and provides a panel transport container that does not leave a contact mark due to vibration during transport, and that can easily perform panel storage work with a simple structure. This is the issue.

A container for transporting a panel, wherein the peripheral wall of the container body is provided with a panel end surface holding part protruding inward of the storage part, and the container body is formed of a foam material The panel end face holding part is formed of a non-foamed resin.

  In this invention, a panel can be accommodated in the accommodating part of a container main body in the state in which the outer peripheral end surface of the panel was hold | maintained by the panel end surface holding part which protrudes from the surrounding wall of a container main body. In this case, since the panel end surface holding part is a non-foamed resin and is a material harder than the container body made of a foaming material having a cushioning property, when the panel vibrates during transportation, the panel end surface holding part passes through the panel end surface holding part. The container body can be elastically deformed to absorb the vibration. Therefore, even when the panel transport container is dropped during transport, the panel can be prevented from being damaged, and the container main body made of the foamed material itself can be prevented from being damaged.

  Further, in the case of the present invention, the panel end surface holding portion is a non-foamed resin and is a hard member, so that the panel contact mark does not remain on the portion of the panel end surface holding portion that directly contacts the outer peripheral end surface of the panel. . In addition, since the panel does not come into direct contact with the container body made of the foam material, the panel contact mark is not attached at the time of vibration of the panel transport container, and the panel and the foam material are not rubbed. There is no generation of dust due to rubbing in the storage unit, and quality deterioration due to conveyance can be prevented.

  Moreover, in the panel transport container according to the present invention, it is preferable that the panel end surface holding portion is detachably fitted by being inserted from above.

  In this case, since the panel end surface holding portion is provided separately from the container main body, the panel end surface holding portion and the container main body, which are respectively formed from separate members, can be manufactured in separate steps. In addition, in the present invention, the panel end surface holding portion can be attached to the container body by a simple operation of inserting the container body from above.

  Moreover, in the panel transport container according to the present invention, it is preferable that the container body is provided on an interposed member made of a foam material that is detachably fitted to the peripheral wall of the panel end surface holding portion.

  In the present invention, the panel end surface holding portion can be provided via an interposing member made of the same foam material as the container body, and the position of the panel end surface holding portion in the storage portion can be changed. By using the interposition member, the size of the storage portion can be changed according to the size of the panel to be stored. Accordingly, it is possible to accommodate a plurality of types of panels with different sizes in one container body.

  Moreover, in the panel transport container according to the present invention, the storage section is partitioned into a plurality of storage sections by a partition wall, and the panel end surface holding section is provided on the peripheral wall of the container body and the partition wall. Also good.

  In the present invention, a plurality of storage portions can be formed in one container body, and storage of a small-sized panel can be accommodated. Moreover, since a panel end surface holding portion can be provided for each partitioned storage portion, the panel end surface holding portion for holding the panel stored in each storage portion is a storage portion rather than the peripheral wall of the container body and the partition wall. Since the panel protrudes to the side, the panel does not directly contact the peripheral wall and partition wall, and as described above, not only the panel end surface holding part but also the peripheral wall and partition wall are left with no trace of contact. can do.

  According to the panel transport container of the present invention, there is no contact trace due to vibration during transport, and the panel storage operation can be easily performed with a simple structure.
