摘要： In a method of molding a heat resistant container whose bottom has an inwardly raised part, firstly a preform is primary blow molded to form a primary blow molded article which is greater at least in length than the container to be obtained as a final product. Then the primary blow molded article is heat shrunk. This heat shrinking is restricted in such a manner that the length of the heat shrunk primary blow molded article from its top to its bottom center is greater than the length of the final product from its top to a peak of the raised part. Then at least the central region of the bottom of the heat shrunk primary blow molded article is inwardly pushed within a secondary blow cavity mold having a bottom mold by vertically moving the bottom mold. Finally in the secondary blow cavity mold, the resulting product is secondary blow molded so that the heel of a heat resistant container, as the final product, has a desired thickness.
