[Technical Field] The present invention relates to a glass substrate for a glass substrate for liquid crystal display, a fluorescent display tube, a thermal head (a glass substrate for therma, and a color filter) Color filter), etc., or a glass substrate transfer case of a glass substrate made of a glass substrate manufactured using such a glass substrate. [Prior Art] In a glass manufacturing factory, a color filter manufacturing plant, and device manufacturing In order to transport the glass substrate (including the completed panel), a glass-based box formed of a resin foamed material disclosed in Patent Document 1 is used in the factory. A resin foamed material that is lightweight and has a high impact effect from the external impact. However, the shape of the box is a plane on the hexahedron side, so when the glass substrate is transported, the box is overturned, the side is In addition, in recent years, the glass substrate transportation container has a tendency to increase in size due to the increase in size of glass. When the plate transporting box is overturned, the impact η which is generated on the glass substrate is changed, and when the glass substrate transporting case is transported, a plurality of large boxes (corrugated boxes, etc.) are used for transportation, in this case, Absorbing the rush, providing space between the adjacent boxes, and performing the loading and unloading operation in this space. However, the space between the boxes is easily changed; ί and there is also a space that is not fully installed, then There will be a transport operation 312XP / invention manual (supplement) / 94-11 / 94123835 board, electric 1 head) Glass-based glass, etc., which are transported to each other as the following glass, because there is a glass base from the substrate 1» Become bigger.

1275541 Reduced. (Patent Document 1) Japanese Patent Laid-Open No. Hei 7 - 1 3 2 9 8 6 SUMMARY OF INVENTION [Problem to be Solved by the Invention] The object of the present invention is to provide a pair of glass substrate transport boxes. The impact of the glass substrate is too large, and when a plurality of glass substrates are transported in a large box for transportation, a uniform space cannot be provided between the adjacent boxes. Accordingly, it is an object of the present invention to provide a permeable substrate transporting case which can reduce the impact on the contained glass substrate even when the glass substrate is turned over. In addition, when a plurality of large boxes for transporting a glass substrate are transported, a glass substrate having a structure in which the space between the adjacent boxes can be set and the efficiency of the transport operation can be improved can be solved (the means for solving the problem). The glass substrate transporting case (b ο X ) of the present invention is a glass substrate transporting box used for a glass feeding substrate, and has an opening region in which a glass substrate can be received, and a main body container that can accommodate the glass, and a container therein The lid that opens and closes the opening region is provided on the outer wall surface of the main body container, and has a linear convex portion on the side of the main body that protrudes outward. Further, in another aspect of the invention, the main body container portion is provided to extend linearly from the bottom side through the opening region side. In another aspect of the invention, the main body container side convex portion faces the outer wall surface of the side wall of the glass substrate. Also 312XP / invention manual (supplement) / 94-11 /94123835 When tipping over, the delivery box is efficient. The delivery box is made of glass. It is stored in a uniform empty L-box. In order to accommodate the above-mentioned glass substrate member, it is extended into a side convex shape, and is set in the system, on the upper 6

In another aspect of the invention, the cover member side convex portion that protrudes outward in the outer wall surface of the cover member and extends in a line shape. In still another aspect of the invention, the main body container side convex portion and the cover member side convex portion are formed in a continuous shape. (Effect of the Invention) According to the glass substrate transporting case of the present invention, the main body container side convex portion extending in a line shape is provided outside the main body container. Therefore, when the glass base delivery box is overturned, first, the outer side is outwardly The protruding body container side protrusion φ is subjected to an impact when it is overturned, and the convex portion of the body container side can be sucked. As a result, it is possible to alleviate the impact imparted by the glass substrate than when the impact is fully absorbed from the side. In addition, since it is not necessary to increase the thickness of the glass substrate case, the glass substrate transfer case is not damaged in quality, and a plurality of glass substrate transfer cases are housed in the side of the adjacent case when the plurality of glass substrate transfer cases are accommodated for transportation. In the main body container portion of the adjacent box, the main container side convex portion abuts, so that a predetermined space can be surely formed between the adjacent glass substrate transporting cases. As a result, a space can be easily incorporated into the impact absorbing member, and the carrying operation can be improved. Further, since the cover member side convex portion that protrudes outward and protrudes outward is provided on the outer wall surface of the cover member, the same effect as that of the convex portion on the side of the device can be achieved. Further, when the main container side convex portion is linearly extended from the bottom side to the opening region, the main body container 312 ΧΡ / invention manual (supplement) / 94-11/94123835 is provided when the glass substrate transporting box is overturned. In the wall panel transporting portion, the glass of the enlarged box side of the glass transporting portion is convexly convex on the line body side.

The 1275541 part abuts to the ground plane in sequence, so it can effectively mitigate the impact. When the glass substrate transporting case is molded, the glass substrate transporting case and the device-side convex portion can be integrally molded by the same material by the material filling direction and the product discharging direction. Further, when it is housed in a large case for transportation, the space created between the adjacent glass substrate cases is a space in which the impact absorbing member is inserted, so that it can be easily incorporated into the impact absorbing member. Further, when the main container side convex portion is provided on the outer wall surface of the side wall of the planar phase of the glass substrate, the impact on the glass substrate can be moderated by the impact on the glass substrate, and the addition to the glass substrate can be effectively avoided. Further, when the main body container side convex portion and the cover member side convex portion are continuously provided, the same effects as those for providing the main body container side convex portion can be obtained. [Embodiment] Hereinafter, a substrate transport case in each embodiment of the present invention will be briefly described with reference to the drawings. (Embodiment 1) First, the structure of the glass substrate case 100 in the present embodiment will be described with reference to Figs. 1 and 2 . 1 is a perspective view showing the structure of the glass transport case in the present embodiment (the cover member is closed). FIG. 2 is a perspective view showing the structure of the glass substrate transfer case in the present embodiment (the cover member is opened). (State of the glass substrate transport case 100) The glass substrate transport case 100 has a storable glass substrate 312XP/invention manual (supplement)/94-11/94丨23835 The molded body transports the opposite direction to the weak impact. The glass is transported to the substrate.) The open area Π 1 A of the whole 101 8 1275541 has a bottom that can accommodate a plurality of glass substrates 1 0 1 . The main body container 1 10 0; and a cover member 1 2 0 that can open and close the opening area 1 1 1 A and close it. The main body container 110 has a square container shape having a bottom surface portion and a side wall 11 1 , 1 1 2, 1 1 3, and 1 1 4 surrounding the four sides. Further, the cover member 120 is formed in a square container shape having a top surface portion and side walls 1 2 1 , 1 2 2, 1 2 3, and 1 24 surrounded by four sides.

Both the main body container 110 and the lid member 1 20 are composed of a resin foam member having a foaming ratio of 3 times to 30 times. The thickness of each of the main body container 110 and the cover member 1 2 0 is about 15 m to 1.0 m in consideration of the strength. Further, the surface of the inner surface (or the inner surface and the outer surface) of the main body container 110 is preferably formed by a skin (s k i η ) structure which is denser than the inner wall portion. In this case, the density from the surface of the skin structure to the depth of 1 mm is greater than the internal density (about 0. 1 when the expansion ratio is 10 times). It is better to be 2 times or more. On the other hand, the surface of the lid member 110 which is produced by the resin foam member is preferably the same as the surface structure. When the surface is formed into a dense skin structure, there is an advantage in that dust resistance (d u s t i n g characteristics) can be prevented and strength can be improved. Although a foaming member of various resins can be used for the resin foaming member, it is preferable to use a polyolefin series foaming member. Examples of the polyolefin-based foam member include polyethylene (low-density polyethylene, high-density polyethylene, ethylene-vinyl acetate copolymer, ionomer (i ο η 〇mer), or the like, or blends thereof Foaming member, polypropylene series foaming member, and the like. Further, other preferred foamed members include polystyrene·polyethylene copolymers. The expansion ratio of the resin foam member is set to 3 times to 30 times, and to 4 9 312XP/invention specification (supplement) / 94-11/94123835

1275541 times ~ 2 5 times the range is better. When the expansion ratio is less than 3 times, the glass substrate is provided with a protective property (bufferability) for weight reduction. On the other hand, when the expansion ratio exceeds 30 times, the foaming ratio is insufficient and the elasticity is excessive. The resin foaming member may be suitably filled in a metal mold filled with a bead series (b e a d s ) or a primary foamed member thereof, and heated at a temperature to be produced. As the foaming agent, a volatile foaming agent, a foaming agent or the like can be used. Further, a combination of two or more kinds of foaming agents can be used. The foaming method is low-pressure foaming, and therefore, a low mold such as an aluminum mold can be used. Instead of such a bead foaming method, a pair of opposing faces on the inner surface of the main body container 110 may be simultaneously formed to simultaneously form a support groove 1 for supporting the glass substrate 110. The support groove M1 is provided on the other surface of the inner surface of the main body container 1 1 相对, but the support groove 1 is provided on the other pair of faces in order to accommodate other sizes of glass. Further, the support ^ is integrally formed on the inner surface of the main body container 110, or may be of a type, and may be fixed to the inner surface of the main body container 110. The support groove 1 has a depth and a width which can be inserted into the side of the glass substrate 110. It is set to have a certain margin when inserted into the glass substrate 1. The number of grooves can be arbitrarily set, and the number of storages of the glass substrate 110 or the weight that can be transported by accommodating the glass substrate 10, that is, the number of grooves on the inner surface of each of the sheets is preferable. The glass base 312XP/invention specification (supplement)/94-11/94123835 in which the TFT (thin film transistor) has been formed cannot be sufficiently filled and the heat is added to become the strength. The foaming agent is polymerized by a predetermined chemical decomposition. The foaming method of metal due to the cost of pearling. In the case of foaming, in Fig. 1, although the plate 101 is not formed, the Μ1 can be formed not only by its members. When the edge portion 0 1 is in the state of the glass, the panel is completed by a person of 15 to 50 strips or a liquid crystal single 10 1275541 (liquid crystal cell), at least the body container 1 1 0 is The volume specific resistance value is changed to 1 X 1 0 3 Ω · cm to 1 X 1 0 12 Ω by a method of foaming a resin containing a conductive polymer or a charge preventing substance of several % to 10%. The resin foaming member of cm is preferable. Thereby, the necessary charge prevention property can be obtained. (mounting structure of ribs)

In the present embodiment, the two main body container side ribs 1 1 5 arranged in parallel are provided on the outer wall surfaces of the side walls 1 1 2, 1 1 4 , respectively. As shown in FIG. 3, the main body container side ribs 1 15 are formed in a cross-sectional shape having a substantially trapezoidal shape, the length of the upper side (L1) is about 5 mm to 100 mm, and the length of the lower side (L2) is about 20 mm to 300 mm. (hi) is about 5 mm to 1 0 0 mm. Further, a portion of the lower end surface of the main body container side rib 1 15 is formed with a predetermined circular arc shape. Further, the mounting position of the side wall ribs 1 1 5 to the side walls 1 1 2, 1 1 4 is set to be more inside than the support groove 1 in order to effectively absorb the impact, or is arranged in the same row as the support groove 1 Preferably, the body rib 151 of the main body is formed in a line shape from the bottom side to the opening area side. Therefore, when the body container 110 is formed, the material 11 312 ΧΡ / invention specification can also be Supplement) /94-11 /94123 835

Further, in the present embodiment, when the cover member 120 is closed on the body 110, the body member side ribs 1 15 and the cover member ribs 1 25 are abutted, but the cover member is used. When the 1 0 0 is closed on the container 110, a certain degree of gap may also occur between the body container side rib 1 15 and the cover member side bar 1 2 5 . Further, the cross-sectional shape of the lid side ribs 1 2 5 is the same as that of the body side ribs 1 15 as shown in Fig. 3 . In the cover member side rib 1 2 5, when the cover member 1 is formed in a line shape from the opening region side to the top surface side, the material filling direction and the molded article are formed at the time of molding the cover member 1. The drawing direction is also formed, and the cover member side ribs 1 2 5 and the body container side ribs 1 1 5 can be integrally formed. (Effects and Effects) In the glass substrate transport case 100 of the present invention, the main container side ribs 1 1 5 extending in a line shape are provided on the outer wall surface of the main body 110, and the glass substrate transport case 1 0 0 When overturning, first of all, by the external protrusion 312XP / invention manual (supplement) / 94-11/94123835 to make 15 external strips of the side body ribs to accommodate 20 to accommodate 12

1275541 The body container side ribs 1 15 and the lid member side ribs 1 2 5 are subjected to a tipping impact, and the body container side ribs 1 15 and the lid member side ribs 1 absorb the impact. Moreover, when the main body container side ribs 1 15 and the cover member side ribs 1 2 5 are linearly extended from the bottom side to the top surface side, the main body container side ribs 11 5 and the cover member side ribs when the glass substrate transport case 1 0 0 is used 1 2 5 is sequentially applied to the ground plane, so it can effectively alleviate the impact.
