PURPOSE: To make it possible to sufficiently wash the side wall surface region of a bottle over the entire surface by diagonally disposing the hole of a nozzle body for sealing the aperture of an injection pipe with a plane perpendicular to an axis of rotation. CONSTITUTION: The nozzle body 12 for sealing the aperture 4 of the injection pipe 1 is provided with the hole 16 and the nozzle body 12 is made rotatable around the axis A of rotation in synchronization with the transfer of the bottle 7. The hole 16 is disposed diagonally at the angleαwith the plane perpendicular to the axis A of rotation. The angleαis preferably about 70 to 85 deg.. Consequently, the side wall surface region of the bottle may be sufficiently washed over the entire surface.
