Provided is a blow molding mold (1) adapted to be mounted to a blow molding device (10) and having a cavity surface (2). The blow molding device (10) has a pressurized liquid supply function of supplying a pressurized liquid (L) to stretch the preform (4) toward the cavity surface (2) and also has a head space defining function of defining head space (Hs) in the container (3) by drawing back a part of the liquid (L) filled into the container (3) through a blow nozzle (12) or by withdrawing a stretching rod (14) from the container (3) filled with the liquid (L). The cavity surface (2) includes a bottom forming surface (2a), a trunk forming surface (2b), a shoulder forming surface (2c), and a mouth forming surface (2d), and the trunk forming surface (2b) includes a flattened portion (2b5) that, in the transverse section, has a flattened shape. |
