When the divided molds 14 and 14 are closed and the pressurized fluid is introduced through the blowing means provided in the middle frame 18, the sheet-like parison 13 is heated by the heating surfaces 19 and 19 provided in the middle frame 18. , 13 is maintained in a molten state, so that the foam 9 is welded to the inner wall surface of the front wall 5 and the back wall 6 of the resin panel 7.

ここで、予め成形した発泡体９はコンテナの中空部内に内装されるものであり、コンテナの断熱性、剛性などの機能を付与するためのもので、ポリエチレン、ポリプロピレン、ポリスチレンなどからなり、表壁５、裏壁６を構成する熱可塑性樹脂と同材質であることが望ましい。また、発泡体９には適宜、ガラス繊維、カーボンファイバー、炭酸カルシウム、タルク、マイカなどの充填材を添加することができる。また、ここでブロー成形とは、筒状のパリソンまたは複数の樹脂シートを溶融押し出し若しくは予備成形した樹脂シートを過熱溶融させるとともに、分割金型間に配置して型締めを行うことにより所望の形状に成形するいわゆるダイレクトブロー成形またはシートブロー成形などをいい、エアの吹込みを伴うか否かについては問わないものである。 Here, the foam 9 molded Me pre is intended to be furnished in the hollow portion of the container, thermal insulation of the container, intended to impart functions such as stiffness, becomes a polyethylene, polypropylene, a polystyrene, Table The wall 5 and the back wall 6 are preferably made of the same material as the thermoplastic resin. Moreover, fillers, such as glass fiber, carbon fiber, calcium carbonate, talc, and mica, can be appropriately added to the foam 9 . Also, here, blow molding refers to a desired shape that is obtained by overheating and melting a cylindrical parison or a resin sheet obtained by extruding or pre-molding a plurality of resin sheets, and placing the mold between molds. The so-called direct blow molding or sheet blow molding, which is formed into a thin film, is used regardless of whether air is blown or not.

本発明によれば、分割金型間に溶融状態のパリソン若しくは樹脂シートを配置し、予め成形した発泡体の内部に無線タグを固定させた後、当該発泡体を分割金型間に配置させて型締めを行い、溶融状態のパリソン若しくは樹脂シートの内面と発泡体の外面を溶着させるので、無線タグは発泡体の内部で成形時の熱が発泡体により遮断され、成形時の熱により変形、破損等無線タグの劣化を防止することができる。 According to the present invention, a parison or a resin sheet in a molten state is disposed between the divided molds, and after fixing the wireless tag inside the preformed foam, the foam is disposed between the divided molds. Because the mold is clamped and the inner surface of the molten parison or resin sheet and the outer surface of the foam are welded , the heat generated during molding of the wireless tag is blocked by the foam inside the foam, and is deformed by the heat during molding. Deterioration of the wireless tag such as breakage can be prevented.
