PURPOSE: To easily correct a deformed plastic bottle by a method wherein a plastic bottle is sealed with a nozzle device, by which air is jetted in the interior of the plastic bottle for air-washing said bottle, and pressurized by air jetted from the nozzle device.
CONSTITUTION: A plastic bottle 2, which is fed from a bottle feeding device to a bottle washing device, is stationed with a bottle holding-down device 24 and at the same time the nozzle 36 of a nozzle device 35 is inserted through the opening part 40 of the plastic bottle 2 in the bottle. Next, the plastic bottle 2 is sealed with the projecting member 39 of the nozzle 36 so as to pressurize the interior of the bottle by means of jetted air blasted from the nozzle 36 in order to correct the shape of the plastic bottle 2. After that, the nozzle device 35 is lifted a little in order to wash the plastic bottle 2 by the air. Next, the nozzle device is further lifted so as to be drawn out of the plastic bottle 2. Thus, the deformed bottle can be corrected easily.
