Abstract:
1. A method for manufacturing a heat-resistant handle-equipped container, comprising 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, the method for manufacturing a heat-resistant handle-equipped container comprising the steps of: 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 such as to inhibit the formation of wrinkles and to inhibit the polyester handle from coming loose or detaching; wherein upon removal the heat-resistant handle-equipped container from said blow-molding mold, the heat-resistant handle-equipped container contracts while the separate polyester handle substantially does not contract such that an angle of inclination of the central axis of the body part below the handle-attaching convexity is corrected to an upright normal state.
