<P>PROBLEM TO BE SOLVED: To facilitate replacement with a new cartridge by making it easy to detach a cartridge used up as a result of having pushed up filler, when replacing the used-up cartridge with the new one, and to prevent an amount of filler pushed out from the cartridge from becoming uneven regardless of repeated cartridge replacement. <P>SOLUTION: While a cartridge body 5 and a body 3 are helically engaged, they are rotated with respect to each other, thereby the body 3 is moved forward with respect to the cartridge body 5. Thus, a presser 6 in the cartridge body 5 is slid forward via a pressing rod 14 and hence filler W is pushed out from the push-out opening 5a in the cartridge body 5. When the filler W is used up as a result of its having been pushed out, the cartridge body 5 and the body 3 are helically disengaged from each other, thereby pulling the cartridge body 5 from an opening in the rear end of the body 3. <P>COPYRIGHT: (C)2011,JPO&INPIT |
