PURPOSE:To provide method for manufacturing two-layered homogeneous hollow molded article having favorable external appearance in one process by general- purpose single layer blow molding machine. CONSTITUTION:The hol1ow molded article concerned is manufactured by blowing parison 5, which is extruded from a die head 2 and then to the surface of which powder 7a made of the desired material is adhered, under the condition that mold is closed. In the above-mentioned manufacturing method, powder under scattered state is fed in a nearly enclosed space 8, which is formed so as to surround the peripheral face of the parison 5, so as to evenly adhere the powder 7a onto the surface of the parison. |
