Abstract
A cleaner for cleaning the nozzle portion of a powder filling apparatus for filling a container with powder by equally evacuating the inside and the outside of the container, and dropping powder through the nozzle portion into the container simultaneously with raising the pressure outside the container is provided. The cleaner includes a cleaning head having a cleaning chamber therein for enclosing the nozzle portion airtightly when the cleaning head is fitted to the nozzle portion; a gas passage disposed in the cleaner head for allowing compressed air to flow therethrough so as to spurt the compressed air to the nozzle portion; and an exhaust passage for allowing powder flowing down in the cleaning chamber together with the compressed air spurted to the nozzle portion to be discharged together with the compressed air.
