Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to articles such as glass substrates mainly used for liquid crystal backlights, hard disks incorporated in personal computers, drive electronic equipment parts for inserting a CD-ROM, and other plate-like parts. When storing and packing in a packaging box,
The present invention relates to a support frame for packaging that also serves as a partition for supporting the members so as not to contact each other and protecting the members as a cushioning material.

[0002]

2. Description of the Related Art When transporting a glass substrate or the like used for a liquid crystal backlight of a display using a liquid crystal, these articles are individually packed with an antistatic wrapping material or a film material. After being packaged in
The packaged articles are supported so as not to come into contact with each other, and are housed and packaged in a packaging box such as a cardboard box.

Conventionally, when such a plate-like or panel-like article is packaged, it is integrally formed from a synthetic resin foamed sheet or a synthetic resin non-foamed sheet as seen in, for example, Japanese Utility Model Laid-Open No. 62-80892. Using a packaging support frame consisting of a bottom plate each having a partitioning convex portion and both side plates that can be bent and erected continuously on both side edges of the bottom plate so that packaged articles packaged with film materials, etc. do not come into contact with each other. , Which was housed in a packaging box such as a cardboard box and packaged.

The above-mentioned packaged articles are taken out in a clean room, but a packaging box such as a corrugated cardboard box is more likely to produce fine powder (paper dust or the like) than a box made of a synthetic resin material, and should be brought into a clean room. Therefore, it has been decided that the product should be taken out from the packaging box while being held by the packaging support frame and carried into a clean room.

However, the packaging support frame in which both side plates are continuously bent and erected with respect to the bottom plate is taken out of the packaging box while holding the packaged article, and is combined with the packaging support frame bent portion. Since the resin material has an elastic recovery force peculiar to the resin material, both side plates are likely to fall outward and be in a deployed state. Therefore, it is necessary to carry both side plates by pressing them with both hands so that they do not fall down, and it takes a lot of time to take them out, the work efficiency is poor, and the holding state of the packaged articles may become unstable.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 9-226867, there is provided a connecting member capable of inserting and locking both end portions with respect to both side plates in the upright state, and connecting both side plates in the upright state by the connecting member. Such a supporting frame for packaging was proposed. According to the method of using the packaging support frame, the connecting members can prevent the both side plates from falling outward, but in addition to the packaging support frame, a separate coupling member is required. It is troublesome to manage and the cost is disadvantageous in terms of cost, and it is necessary to lock both end portions of the connecting member to both side plates, which makes packaging work difficult.

The present invention has been made in view of the above, and uses a separate connecting member as a packaging support frame for supporting and packaging a packaged article such as a glass substrate for a display in a partitioned state. The present invention provides a supporting frame for packaging that can easily and surely hold both upright side plates in a predetermined upright state without doing so.

Thus, the both side plates at the time of standing can be easily and surely held in the connected state, and the phenomenon that the both side plates tend to fall outward can be prevented. Therefore, even when the packaged article is taken out from the packaging box together with the packaging support frame, it is not necessary to hold the both side plates so that they can be carried easily and safely.
When the side plates are connected to each other by the connecting piece, it is possible to hold the packaged article in a predetermined supporting state both when it is stored and when it is taken out.

Particularly in the case of the present invention, since the connecting piece is integrally connected to the side plate or the top plate, it is easier to manage in manufacturing and use as compared with the case where a separate connecting member is used. Yes, it is environmentally friendly and has an advantage in cost.
