摘要： In a plastic container manufactured by melting blow molding a heated and molten parison extruded from an extruder, a mouth 3 and/or a specified part of a body 2 has a thicker thickness than the body proper. One or more thick parts of the body 2 are continuously or discontinuously formed over part or all a peripheral, height or helical direction of the body of the container. The container enjoys enhanced rigidity, appearance and functionality even when the thickness of its body is considerably reduced.
