Blow molding apparatus

A blow molding apparatus for forming a resin container by blow-molding a preform, the blow molding apparatus comprising:

• a primary blow molding station including:
• an injection molding part configured to injection-mold a plurality of the preforms simultaneously;
• a primary blow molding part configured to blow-mold the preform to form a first blow-molded article;
• and
• a first transport device including a first transport path which connects the injection molding part and the primary blow molding part, and configured to intermittently circulate and transport a plurality of the preforms and the first blow-molded article along the first transport path at a predetermined interval;
• and
• a secondary blow molding station installed independently of the primary blow molding station, the second blow molding station including:
• a secondary blow molding part configured to blow-mold the first blow-molded article to form the resin container;
• and
• a second transport device configured to hold the first blow-molded article at a downstream side of the primary blow molding part in the first transport path and transport the first blow-molded article to the secondary blow molding part.
