A method for ejecting a vessel (12), carried by a transporting device (10), the vessel (12) being provided with a neck (16) including a mouth (18), the transporting device (10) including: a mobile support (28); a gripping mandrel (30) that grips by vertical engagement with the neck (16); an ejection face (64) mounted on the mobile support (28), the gripping mandrel (30) being mounted vertically slidable relative to the ejection face (64) to allow the gripping mandrel (30) to be extracted from the neck (16) when it slides via contact between the ejection face (64) and a bearing face (24) of the neck (16); characterized in that the bearing face (24) of the neck (16) is formed by a shoulder face that protrudes radially towards the outside relative to the mouth (18) and is arranged under the mouth (18) in the vertical direction.

A method for molding a hollow molded article, which can suppress deformation of a preform and shorten a molding cycle of the hollow molded article, and a stretching rod and an injection stretch blow molding machine used in the method are provided. The method for molding a hollow molded article, includes: an injection molding process of injection molding a preform; and a blow molding process of obtaining a hollow molded article by stretch blow molding the preform in a blow molding section. The blow molding process includes a preform supporting step of inserting a distal end portion of a stretching rod into the preform and bringing the distal end portion into contact with the preform to support the preform, and a preform separation step of supplying blow air into the preform to release the contact between the preform and the distal end portion.
