【特許請求の範囲】
【請求項１】別々に溶融された樹脂をクロスヘッドダイの樹脂用流路内で合流させて多層パリソンを成形し、クロスヘッドダイの下方に設けたブロー成形金型で表面に表皮材を有する多層状中空成形品をブロー成形する方法であって、別々に溶融された基体樹脂と接着性樹脂とを基体樹脂を内層に、接着性樹脂を外層に位置させてクロスヘッドダイの樹脂用流路内で合流して軟化した少なくとも２層状のパリソンで流下させ、該少なくとも２層状のパリソンを、前記クロスヘッドダイの下方に設けた型開状態の成形金型に配設した表皮材が最外層に位置するよう金型間に垂下させ、所定のパリソン長さになった後表皮材と共に型閉めし、成形金型内に閉じ込められた前記少なくとも２層状のパリソン内に加圧気体をその表皮材が金型内面に密着する状態に流入して、表皮材を前記少なくとも２層状パリソンの接着性樹脂と接着させることを特徴とする表皮一体の多層状中空成形品のブロー成形方法。
[Claims]
1. A multi-layer parison is formed by merging separately melted resins in a resin flow path of a crosshead die, and a blow molding mold provided below the crosshead die has a skin material on the surface. This is a method of blow molding a multi-layer hollow molded product, in which the separately melted base resin and adhesive resin are placed in the inner layer of the base resin and the adhesive resin in the outer layer, and the flow path for the resin of the cross head die. joins the inner flowed down in the parison of at least 2 layers ized soft, said at least a parison 2 layered skin material is disposed in the molding die of a mold opening state provided below the crosshead die outermost It hangs down between the molds so that it is located at, and after reaching a predetermined parison length, the mold is closed together with the skin material, and a pressurized gas is applied to the skin material in the at least two-layered parison confined in the molding mold. A method for blow molding a multi-layer hollow molded product with an integral skin, which comprises flowing into a state of being in close contact with the inner surface of the mold and adhering the skin material to the adhesive resin of the at least two-layer parison.

[Means for solving problems]
In the present invention, separately melted resins are merged in a resin flow path of a crosshead die to form a multi-layer parison, and a blow molding die provided below the crosshead die has a skin material on the surface. This is a method of blow molding a layered hollow molded product, in which a separately melted base resin and an adhesive resin are placed in the inner layer of the base resin and the adhesive resin is placed in the outer layer in the resin flow path of the crosshead die. in passed down at least two layered parison was merged turned into soft, it said at least a parison 2 layered skin material is disposed in the molding die of a mold opening state provided below the crosshead die in the outermost layer It hangs down between the molds so that it is located, and after reaching a predetermined parison length, the mold is closed together with the skin material, and the skin material puts a pressurized gas into the at least two-layered parison confined in the molding mold. This is a molding method capable of easily and surely adhering the skin material to the adhesive resin of at least two layers of parison by flowing into a state of being in close contact with the inner surface of the mold.
