Easily molding resin A such as polyethylene terephthalate (PET) and hard-molding resin B such as PVC, styrol, ABS, acryl or acrylonitrile are injection-molded to form double layer parison with base. Molding product with internal spce is obtained from the axially dilated parison by air-blowing, of which resin A and B are simultaneously dilated under the thermal deformation temperature for resin A. The following figures are cross section of the parison with base and that of final product, respectively.
