PROBLEM TO BE SOLVED: To provide an inert gas replacing device which has an inert gas blowout face that can be easily removed for cleaning when the blowout face gets dirty or the mesh thereof clogs and prevents a soiled material from entering a nozzle chamber as well to simplify sanitation work for the device and improve the operating rate of a line. SOLUTION: According to the inert gas replacing device, a nozzle structure 1 having the box-like nozzle chamber 2 is arranged along a container transfer line. The nozzle chamber 2 has the inert gas blowout face that is covered with a nozzle plate 4 having a number of inert gas blowout holes. The nozzle plate 4 is fitted slidably into the opening end of the body of the nozzle chamber 2 in a detachable manner. The nozzle plate 4, therefore, can be removed easily from the nozzle chamber 2 to be cleaned when the contents are scattered onto the nozzle plate 4 to soil it. The nozzle plate 4 attached to the chamber 2 prevents the scattered contents from entering the chamber 2, thus keeping the chamber 2 clean. COPYRIGHT: (C)2006,JPO&NCIPI
