Abstract
A pressure is accumulated in advance in a cylinder (35), which is used for conversion to air for the outside of a mouth, with an opening-closing valve (V3) of the cylinder (35) being closed, and when a pressurized liquid (L) is supplied into a preform (PF) through a blow nozzle (13) by actuating a plunger pump (31) and by opening a sealing body (15), the opening-closing valve (V3) of the cylinder (35) is opened to thereby apply the pressure accumulated in the cylinder (35) to the liquid (L) supplied into the preform (PF).
