  The present invention is the glass substrate storage device, wherein the holding groove of the presser plate extends over the entire upper edge of the glass substrate.

  The present invention provides a glass substrate storage device, wherein a first surface fastener material is provided in a recess of a lid, and a second surface fastener material that engages with the first surface fastener material is provided on a presser plate. It is.

  The present invention is a glass substrate storage device characterized in that the storage box and the lid are made of polypropylene or piocelan, and the presser plate is made of foamed polyethylene that is softer than the storage box and the cover.

  As described above, according to the present invention, when a glass substrate is stored in a glass substrate storage device and transported, the glass substrate is not damaged even if an impact is applied to the glass substrate storage device. For this reason, a glass substrate can be conveyed safely and reliably.

  Embodiments of the present invention will be described below with reference to the drawings.

  1 to 4 are views showing an embodiment of a glass substrate storage device according to the present invention.

  As shown in FIGS. 1 to 3, the glass substrate storage device 10 stores and transports a glass substrate 30 among a glass manufacturer, a color filter manufacturer, and a device manufacturer. A display panel, a plasma display panel, and these materials can be considered.

  The glass substrate 30 has a rectangular shape, the size of which is, for example, 1250 mm × 1100 mm, and the thickness of, for example, 0.6 mm.

  The glass substrate storage device 10 as described above has a bottom portion 13 and a side portion 12 that forms an opening 11a, a storage box 11 that stores a plurality of glass substrates 30 arranged in a vertical direction, A lid 20 having a frame body 21 that is attached to the opening 11a and engages with the upper end 12b of the side portion 12, and a presser that is provided on the back surface of the lid body 20 and holds the glass substrate 30 in the storage box 11 from above. And a plate 25.

  Among these, a plurality of support grooves 13 a that support the lower edge of the glass substrate 30 are provided in the bottom portion 13 of the storage box 11, and a plurality of support sides of the glass substrate 30 are supported in the side portion 12 of the storage box 11. The support groove 12a is provided.

  Further, the storage box 11 has an opening 11a formed by the side portion 12a, and the frame body 21 of the lid body 20 is engaged and fixed to the upper end 12b of the side portion 12a as described above. 11 openings 11a are covered.

  Incidentally, the frame body 21 of the lid body 20 is formed along the periphery of the lid body 20, and a recess 22 is formed inside the frame body 21. In this case, a region surrounded by the frame body 21 on the back surface of the lid body 20 is the recess 22.

  The holding plate 25 provided on the back surface of the lid body 20 holds the glass substrate 30 in the storage box 11 from above, and the glass substrate 30 enters the surface of the holding plate 25 on the glass substrate 30 side. In addition, a plurality of holding grooves 27 for holding the glass substrate 30 are provided. The presser plate 25 has substantially the same shape as the concave portion 22 of the lid body 20, so that the presser plate 25 can be fitted in the concave portion 22 of the lid body 20 in a close state. The holding plate 25 is preferably formed from a single plate, but may be formed from two plates or three plates separated from each other.

  Even when the presser plate 25 is formed from a plurality of plates, the presser plate 25 is fitted into the recess 22 of the lid 20 as a whole so as not to move in the recess 22.

  Further, the presser plate 25 fitted in the concave portion 22 of the lid 20 has a plurality of holding grooves 27, which are continuous over the entire length of the upper edge 30 a of the glass substrate 30. It extends. Therefore, the entire length of the upper edge 30a of the glass substrate 30 can be firmly held by the holding groove 27 of the pressing plate 25, and a portion that is not held by the holding groove 27 in the upper edge 30a of the glass substrate 30 does not occur.

  As described above, the presser plate 25 is fitted in the recess 22 of the lid 20, but the first surface fastener material 23 fixed to the inner surface of the recess 22 and the second surface fastener fixed to the upper surface of the presser plate 22. The presser plate 25 is fixedly held in the recess 22 of the lid 20 by the material 26. Therefore, when the lid 20 is removed from the storage box 11, the presser plate 25 can be pulled away from the storage box 11 together with the lid 20.

  Next, the material of each member will be described. The storage box 11 and the lid body 20 are made of, for example, polypropylene, and the presser plate 25 is made of a foamed resin that is soft with respect to both the storage box 11 and the lid body 20, for example, foamed polyethylene. In addition, you may form the storage box 11 and the cover body 20 from Piocelan.

  Next, the operation of the present embodiment having such a configuration will be described below.

  First, a plurality of glass substrates 30 are stored and held in the storage box 11 with the lid 20 and the presser plate 25 removed from the storage box 11. In this case, the glass substrate 30 is engaged with the holding groove 13 a of the bottom portion 13 and the holding groove 12 b of the side portion 12.

  Next, the pressing plate 25 is placed on the glass substrate 30 stored in the storage box 11, and the upper edge 30 a of the glass substrate 30 is inserted into the holding groove 27 of the pressing plate 25.

  Next, the lid body frame 21 is engaged with the upper end 12 b of the side portion 12 of the storage box 11, and the opening 11 a of the storage box 11 is covered with the lid body 20. In this case, the presser plate 25 is fitted into the recess 22 of the lid 20, and the presser plate 25 is fixed inside the lid 20 by the first surface fastener 23 and the second surface fastener 26.

  The glass substrate storage device 10 storing a plurality of glass substrates 30 is then transported. Even when an impact is applied to the glass substrate storage device 10 during transportation, the presser plate 25 does not move within the recess 22 of the lid 20. Therefore, the glass substrate 30 having the upper edge 30a held by the holding groove 25a of the presser plate 25 does not move or deform in the storage box 11, and the glass substrate 30 is safely damaged without damaging the glass substrate 30. Can be stored and transported.

  Here, a comparative example of the present application will be described with reference to FIG. As shown in the comparative example shown in FIG. 4, two presser plates 25 are arranged in the recess 22 surrounded by the frame body 21 of the lid 20, and these presser plates 25 are movable in the recess 22. In the case where the press plate 25 is fixed to the lid 20 with the surface fastener material, it is considered that the press plate 25 slides in the recess 22 when an impact is applied to the glass substrate storage device.

  When the presser plate 25 moves, the presser plate 25 is inclined in the recess 22, and the holding groove 27 of the presser plate 25 is also inclined with respect to the lid body 20. As a result, it is conceivable that an excessive force is applied from the holding groove 27 to the upper edge 30a of the glass substrate 30 to break the glass substrate 30.

  On the other hand, according to the present invention, since the presser plate 25 is fitted and fixed in the recess 22 of the lid 20, the presser plate 25 is not affected even if an impact is applied to the glass substrate storage device 10. It does not move within the recess 22 and the holding groove 27 of the presser plate 25 is not inclined with respect to the lid body 20.

  Furthermore, since the holding groove 27 of the holding plate 20 extends over the entire length of the upper edge 30a of the glass substrate 30, the entire length of the upper edge 30a of the glass substrate 30 can be firmly held by the holding groove 27.

  As described above, according to the present embodiment, when the glass substrate 30 is stored and transported in the glass substrate storage device 10, the glass substrate 30 is damaged even if an impact is applied to the glass substrate storage device 10. And can be transported safely.
