Abstract
A method for manufacturing shaped articles by injection-blow molding. A thermoplastic material is first formed into a bottomed parison by injection-molding said material onto the surface of an injection molding core. The bottomed parison formed on the surface of the core is cooled to a temperature at which it is easily removed from the core, and is removed therefrom. The parison is heated again to a predetermined temperature and the reheated parison is transferred to a blow molding mold, wherein the parison is blow-molded.
