摘要： When a preform having been molded while released from a mold at an earlier timing in an injection stretch blow molding machine is stretched and blow molded, the bottom of the preform is prevented from rupturing and the bottom of a hollow molded article is prevented from being uneven in wall thickness to produce such a hollow molded article without defect bottom by the injection stretch blow molding machine. A method for producing a hollow molded article includes: an injection molding process of injection molding a preform; and a blow molding process of blow molding the preform to obtain a hollow molded article. The blow molding process allows a tip of a stretching rod cooled to a temperature between 50°C and 90°C to be brought into contact with the bottom of the preform in a softened state obtained in the injection molding process, and to press down the bottom of the preform while the bottom is cooled.

摘要： A blow molding machine 1 has a blow molding section (10,11) 10, an ejection section (100,20) 20, and a delivery unit (100,102,2.1) 100. In order to deliver a plurality of containers B to a device (200) 200 of a post-process subsequent to the blow molding machine, the delivery unit (100,102,2.1) includes a rail (102A,102,520) for holding, delivering and guiding the plurality of containers, and an elevation block (100,110,112) raised and lowered relative to the rail (102A,102,520). The elevation block (100,110,112) includes a plurality of blades (112), an endless member (114) to which the plurality of blades (112) are fixed at a blow molding pitch (P1,P2), and a drive portion for driving the endless member (114) to run.
