In FIG. 9, reference numeral 01 denotes a glass substrate carrying box, which comprises a bottomed main body 02 and a lid (not shown). Inside the main body 02, a glass substrate supporting groove 04a is provided. A pair of the interior plates 04 are inserted. The glass substrates 03 are engaged and supported one by one in the grooves 04a of the interior plate 04 facing each other, and the lid is placed on the main body 02 so as to press the upper side of the glass substrate 03 from above and used for conveyance. . Since the main body 02, the lid, and the interior plate 04 are made of resin foam, they have cushioning properties and can absorb shock even when shock or vibration is applied.

[0004]

However, in the conventional glass substrate carrying box, there is no fear of damage to the glass substrate 03 when an external force that is contained within the cushioning property of the resin foam acts. When a slightly strong impact is applied to the box main body 02, the entire body is made of the same resin foam and the glass substrate 03 is supported in the four vertical and horizontal directions. It was often transmitted and damaged.

The present invention has been made by paying attention to such a problem, and even if a large external force is applied to the carrying box, the glass substrate contained inside is not easily damaged. An object is to provide a glass substrate transport box.

[0006]

In order to solve the above problems, a glass substrate carrying box of the present invention is a glass substrate carrying box comprising a box body having a bottom and a lid body, wherein the lid body The glass substrate contacting part is made of a flexible material, the bottom plate of the bottomed box body is made of a harder material than the glass substrate contacting part, and the glass substrates are held in parallel so as not to contact each other. It is characterized in that it has a glass substrate supporting portion in which a plurality of possible grooves are formed, and holds the glass substrate by sandwiching it between the glass substrate supporting portion and the glass substrate contacting portion.

In the glass substrate carrying box of the present invention, it is preferable that the glass substrate contact portion is made of polyethylene foam and the glass substrate supporting portion is made of polypropylene foam. By doing so, the glass substrate can be reliably and safely transported by utilizing the lightness strength, the resistance to friction and cracks, and the cushioning property of the foam.

In the glass substrate carrying box of the present invention, it is preferable that the glass substrate abutting portion is constituted by an air bag. By doing so, it is possible to provide a lid body whose flexibility is freely adjusted by adjusting the air pressure.

In the glass substrate carrying box of the present invention, it is preferable that both ends of the glass substrate are guided by a plurality of parallel grooves formed in a pair of side plates. With this configuration, the left and right parallel grooves function as guides when the glass substrate is carried in and out of the box, which facilitates the work.

In the glass substrate carrying box of the present invention, it is preferable that the box body with a bottom is frame-reinforced by a frame body made of a hard material such as aluminum. In this way, the box is reinforced with a frame made of a hard material, so a robust box can be provided, and the box will not be deformed even when it comes into contact with other articles or is stored for a long time. There is no.

In the glass substrate carrying box of the present invention, it is preferable that the box body with a bottom is constructed by combining the bottom plate and four side plates. In this way, the bottomed box body can be made by assembling the plate body, so it does not take time and effort to manufacture, and the bottom plate corresponds to the lid body and can freely select the material independent of the side plate. it can.

The glass substrate contacting pad 58 made of a body is sandwiched so as to be pressed, and the left and right sides are free. Therefore, even when a strong impact is applied from the outside, the soft material absorbs energy, and the glass substrate Since the force is not directly transmitted to G, the glass substrate G can be prevented from being damaged.

Further, since the upper and lower sides of the glass substrate G are supported by the foam, the glass substrate G can be safely used by utilizing the lightness strength, the resistance to friction and cracks, and the cushioning property of the foam. Therefore, reliable transport can be performed.

Further, when each of the glass substrates G is carried in and out of the box body 2, the left and right parallel grooves 46 of both side surface pads 48 attached to the inner surfaces of the pair of side plates 8a and 8b function as guides. Therefore, the work of taking in and out the glass substrate G becomes easy.

In addition, the bottomed box body 2 includes pad-shaped reinforcing corner plates 18 at four corners for reinforcing the bottom plate 4, strip-shaped reinforcing plates 14a, 14b, 16a, 16b, and the bottom frame 10.

Since it is reinforced with a frame consisting of a and 24b,
A robust box body 2 can be provided, and the box body 2 is not deformed even when it comes into contact with other articles or is stored for a long time.

In the above embodiment, instead of the glass substrate contacting pad 58 made of polyethylene foam which is juxtaposed and attached to the back surface of the top plate 32 of the lid 3, the glass substrate G is contacted. It is also possible to configure the part to be filled with an air bag (not shown). By doing so, it is possible to freely adjust the degree of flexibility and appropriately maintain the pressing force against the glass substrate G by adjusting the air pressure.

Although the embodiments of the present invention have been described above with reference to the drawings, the specific configuration is not limited to these embodiments. For example, the number of the glass substrate supporting pads 44 and the glass substrate contacting pads 58 is not limited. It is appropriately determined in consideration of the weight of the glass to be stored, the material of the pad, and the like, and the example in which each pad is attached as a separate body from the bottom plate and the side plate is shown, but it is formed integrally. The present invention may include modifications and additions within the scope of the present invention.
