Description
本発明は、カラーフィルタ等の膜面が形成された大型液晶表示用のガラス基板の梱包、運搬において安全、かつコンパクトに梱包する事が出来るとともに輸送中・保管中のパーティクル、水分、有機物の影響を防止する梱包、運搬方法に関し、特に、真空パックを用いたガラス基板の梱包方法及びその包装体に関する。 The present invention is capable of packing a glass substrate for a large-sized liquid crystal display having a film surface such as a color filter, which can be safely and compactly packed and transported, and is also affected by particles, moisture, and organic substances during transportation and storage. In particular, the present invention relates to a glass substrate packaging method using a vacuum pack and a package thereof.
従来は、液晶表示用等のガラス基板を梱包、運搬する場合には、ポリプロピレン製の発泡ケース、樹脂製ケース等が用途に応じて用いられている。この方式は主に第５世代といわれる長さ１ｍ強までのガラス基板の梱包、運搬に使用されており、運搬性に優れている反面ケース内のガラス基板の間隔が２０ｍｍ程度必要な為、ケース内に収納出きる枚数とトラック等で運搬できる枚数に限度があり、また空になったケースの返却では非効率な方法とされていた。 Conventionally, when packing and transporting a glass substrate for liquid crystal display or the like, a polypropylene foam case, a resin case, or the like is used depending on the application. This method is mainly used for packing and transporting glass substrates up to over 1m in length, which is said to be the fifth generation, and is excellent in transportability, but the distance between the glass substrates in the case is about 20mm. There is a limit to the number of items that can be stored inside and the number of items that can be transported by truck, etc., and returning empty cases has been an inefficient method.
上記現象を考慮してリブで区画された中空部を有する箱本体と蓋体をシール材で密閉梱包する方法が提案されている（例えば、特許文献１参照）。 In consideration of the above phenomenon, a method has been proposed in which a box body having a hollow portion partitioned by ribs and a lid are hermetically packaged with a sealing material (see, for example, Patent Document 1).
さらに、ガラス基板等の板材の１枚づつの表裏を２枚の保護フィルムで挟み密閉梱包する方法等も提案されている（例えば、特許文献２参照）。 Furthermore, a method of sealing and sealing a sheet material such as a glass substrate by sandwiching the front and back of each sheet between two protective films has been proposed (for example, see Patent Document 2).
上記特許文献１はリブで区画された複数の中空部を有する箱体にガラス板を立てて収納し、蓋体との隙間を弾性シール材で密閉し留め具で固定する梱包とされている。しかし、箱体が従来の発泡ケースと同じように基板間の間隔があるためコンパクトな梱包には不向きとされ、さらに箱体の内部を常に清浄な状態に保つことは困難とされてきた。 In Patent Document 1, a glass plate is stood and stored in a box having a plurality of hollow portions partitioned by ribs, and a gap between the lid and the lid is sealed with an elastic sealing material and fixed with a fastener. However, since the box has an interval between the substrates as in the conventional foam case, it is not suitable for compact packaging, and it has been difficult to keep the inside of the box always clean.
次に、特許文献２に記載の手段は、板材１枚１枚を保護フィルムで挟む為、保護フィルムの使用量が膨大なものとなり、また梱包形態のコンパクト化が困難であった。 Next, since the means described in Patent Document 2 sandwiches each plate material with a protective film, the amount of the protective film used is enormous, and it is difficult to make the packaging form compact.
以下に公知文献を示す。
