ABSTRACT:
A process for producing a blow molded article, in which a parison is disposed between an outer face-forming mold section having an air bleeding hole and a bottom face-forming mold section and adjacent said bottom face-forming mold section. A resin film is disposed between the parison and the outer face-forming mold section. Then the outer face-forming mold section and bottom face-forming mold section are closed. Then air is blown into the parison to inflate the parison to form the end product and simultaneously to mold the resin film and the end product in an integral relationship with each other.
