In the present invention, a blow nozzle (30), that guides blow air to a molding product (20) held in a blow cavity mold (10) by a flange part (22B) provided to a neck part (22), has the following: a nozzle main body (50); and an outer nozzle (80) integrally connected to the nozzle main body and disposed at the periphery of the neck part. The outer nozzle has the following: a first surface (84) that is in pressing force contact with the flange part and is continuous in the circumferential direction; and a second surface (86) that is disposed more to the radial outer-side than the first surface is and is in contact with the blow cavity mold. From when the nozzle main body moves and the first surface comes into contact with the flange part and until the second surface comes into contact with the blow cavity mold and the movement of the nozzle main body stops, the first surface of the outer nozzle is subjected to overdrive and the flange part is hermetically sealed by the first surface. |
