Description

  The present invention relates to a transport container used for transport and storage of glass substrates for liquid crystal display and plasma display and other various glass substrates in addition to the base glass.

  Conventionally, a container body and a lid made of a synthetic resin foam having a buffering property as a transport container for storing and transporting a plurality of relatively large glass substrates for liquid crystal display or plasma display in parallel A supporting groove made of a vertical groove is formed at equal intervals on the inner surface of one opposite side wall of the container body, and the side edges of the glass substrate are inserted into the supporting groove. A device that is supported and stored so as not to contact is known.

  Further, in addition to providing a bottom pad having a support groove for protecting the lower end portion of the glass substrate on the bottom plate in the container body, a support groove for protecting the upper end portion of the glass substrate protruding above the container body. It has also been proposed to provide a ceiling pad having a surface (for example, Patent Documents 1 and 2). Since the top pad needs to fit the upper end of the glass substrate into the support groove during the deposition operation, it covers the upper end of the glass substrate separately from the lid, and then the lid is deposited. I am doing so.

  By the way, in recent years, the glass substrate has been made thinner, and as a result, even when a transport container provided with a bottom pad, a top pad or the like is used, damage during transportation has increased. This is because the glass substrate becomes thinner due to vibration during transportation, and the container itself is deformed due to external factors such as vibration during transportation and impact due to contact with other objects. The internal glass substrate is greatly bent, and the left and right side walls holding the glass substrate and the groove from the support groove of the top pad are generated, and as a result, the glass substrates interfere with each other and come into contact with each other. Conceivable.

  This point will be described. As shown in FIGS. 11 and 12, in the transport container including the bottom pad 104 and the top pad 105, the lid 102 is externally fitted to the upper end of each side wall 112 (112 a, 112 b) of the container body 101. Generally, it is in the form of being attached, but due to play of this fitting part, it is easily affected by vibrations during transportation and impact due to contact with other objects, and the side wall of the container body 101 In particular, the side wall 112a facing the glass substrate B tends to be bent and deformed inward with respect to the lid 102.

  That is, outward deformation of the side walls 112 of the container body 101 with respect to the lid 102 is restricted by the lid 102, and inward deformation of the left and right side walls 112b having the support grooves 113 is caused by the glass substrate B itself. However, the side wall 112a facing the plate surface of the glass substrate B does not have a part that restricts deformation inward, so that it may be bent inward due to vibration or external impact. There is.

  If the deformation occurs such that the side wall 112a is displaced inward relative to the lid body 102 or the lid body 102 is displaced outward relative to the side wall 112a, the lid body 102 is deformed as shown in FIG. There is a shift between the position of the support groove 152 of the top pad 105 mounted on the lower surface of the top plate 121 and the position of the support groove 113 on the inner surface of the side wall of the container body 101. As a result, the support grooves 113 and 152 The glass substrate B that is fitted and held in parallel at a constant interval is greatly bent, and the glass substrate B is likely to be damaged due to a groove detachment or interference.

Among these, it is preferable to use a composite resin containing polystyrene and polyethylene. The foaming ratio of the foam is preferably 3 to 50 times.

  The inner lid 3 can also be made of the same foamed resin molded body as described above, but is basically a foam having the same shape retention and elasticity as the lid 2, or a slightly more flexible holding body. A foam having shape and elasticity is used. For example, when the lid 2 and the inner lid 3 are made of the same material, the inner lid 3 is a foam having the same expansion ratio as the lid 2 or a foam having a higher expansion ratio and higher elasticity than the lid. Used.

  Further, the bottom pad 4 and the top pad 5 are the same synthetic resin bead-molded foams as the inner lid 3 and have the same shape retention and elasticity as the container body 1 and the lid 2. Synthetic resin foams having a certain property or synthetic resin foams having slightly flexible shape retention and elasticity are used. More preferably, a foam having elasticity that is slightly more flexible than the container body 1 and the lid 2 is preferably used.

  When the synthetic resin foam having elasticity that is slightly more flexible than the container body 1 and the lid body 2 is used as the inner lid 3, the top pad 5 can be foam-molded integrally with the inner lid 3.

  1 to 9, the grooved bottom pad 4 (each pad piece 41) is provided on the upper surface of the bottom 11 of the container body 1 and the grooved top pad 5 ( Each pad piece 51) is arranged and installed on the lower surface of the top plate 31 of the inner lid 3 respectively. Then, both side ends of the glass substrate B to be accommodated are inserted into the support grooves 13 on the left and right side walls 12b and 12b of the container body 1, and the lower ends are fitted into the support grooves 42 of the bottom pad 4 and supported.

In the interior, the opposite side walls 32a, 32a of the inner lid 3 intersect with the side walls 12b, 12b having the supporting grooves 13 of the container body 1, that is, the plate of the glass substrate B accommodated therein. The side walls 12a and 12a facing the surface are internally fitted to the upper end portions. Therefore, the displacement due to the outward bending deformation of the side walls 12 of the container body 1 with respect to the lid body 2 is restricted by the lid body 2, and the left and right side walls 12b and 12b having the supporting grooves 13 are inwardly bent and deformed. The displacement due to is regulated by the glass substrate B in which it is accommodated. In addition, on the side of the side wall 12a, 12a facing the plate surface of the glass substrate B, the inward deformation displacement of the side wall 12a can be regulated by the inner lid 3. If the side walls 12 a and 12 a of the container main body 1 are displaced inward relative to the lid 2, the inner lid 3 is also displaced following the container main body 1. For this reason, a deviation may occur between the position of the support groove 52 of the top pad 5 mounted on the lower surface of the top plate 21 of the inner lid 2 and the position of the support groove 13 on the inner surface of the side wall of the container body 1. Absent. Therefore, the glass substrate B that is fitted in the supporting grooves 13 and 52 and held in parallel at a constant interval does not generate large deflection or slippage, and damage caused by the large deflection interference of the glass substrate B is prevented. As a result, the glass substrate B can be made thinner.

  The transport container of the present invention can be suitably used for transporting and storing various types of plate-like bodies that are vulnerable to impacts, such as raw glass, a relatively large glass substrate such as a glass substrate for liquid crystal display or plasma display.
