A heat-resistant container molding apparatus and method which are compact and inexpensive and can reliably increase the crystallinity, reduce the residual stress in a container filled with a hot content such as thermally sterilized fruit juice, and prevent a thermal deformation with improved container stability at a raised temperature. The apparatus has a receiving and removing unit for receiving primary moldings obtained by blow-molding preforms and for removing final products, a heat treatment section for heating the primary moldings by bringing the primary moldings into contact with the inner wall of a heat treatment mold while pressurizing the interior of the primary moldings within the heat treatment mold, a final molding section for blow molding intermittent moldings into final products within a final blow mold, and a rotary plate, neck support fixing plate and neck support member for conveying the moldings through the receiving and removing unit, heat treatment section and final molding section.

1. A method of molding a heat-resistant container, comprising:a providing step for providing a primary blow mold, a heat treatment mold and a final blow mold, each of which has split molds to be champed by a mold clamping mechanism, wherein said primary blow, heat treatment and final blow molds are rectilinearly disposed; a primary molding step for blow-molding injection molded preforms into primary moldings in said primary blow mold; a heat treating step for heat treating the primary moldings to obtain intermediate heat treated moldings by bringing the primary moldings into contact with an inner wall of said heat treatment mold while pressurizing an interior of each of the primary moldings within said heat treatment mold; and a final molding step for blow-molding the intermediate heat treated moldings into final products in said final blow mold.
