Method for manufacturing a heat-resistant handle-equipped container

摘要

The present invention provides a method for manufacturing a heat-resistant handle-equipped container. The method comprises the steps of insert-molding a separate polyester handle onto a top part of a body part of a hollow container when the container is formed by blow-molding a polyester preform and blow-molding with a blow-molding mold positioned so that a central axis of the body part below a handle-attaching convexity provided to a concavity on a top half of the body part is inclined 1°±0.5° toward the handle-attaching convexity; and heat-setting a wall surface that surrounds the handle-attaching convexity in the concavity.
