PURPOSE:To prevent contamination of a work place, save labor for recovering a cleaning liquid, prevent a resin residue from mixing in a product, and improve safety by removing the resin residue attached to a nozzle tip inner wall by a nozzle foot inner drum which is movable up and down on the inner face of the nozzle foot. CONSTITUTION:A nozzle foot outer drum 12 whose foot is expanded is equipped, at its one end, with an origin plate 9 having a size equivalent to a diameter of the outer drum 12. The origin plate 9 surrounds the outer drum 12 from the outside in a U-shape with its both ends and fixes a frame 6 for pulling down a nozzle foot inner drum. The frame 6 and the nozzle foot inner drum 3 are integrally connected by a nozzle foot inner drum fixing bar 10 at right and left parts of the frame 6 which is in contact with the outer drum 12. Nozzle foot drum pull-down operation areas H are formed by cutting at right and left parts of the outer drum 12 which are in contact with the frame 6 such that the nozzle foot inner drum 3 can be pulled down. When a resin residue is attached on a nozzle tip inner wall 2c, a hand hold handle 4 fixed to the frame 6 is pulled down by a width W so as to scrape by a head end 3a of the nozzle foot inner drum 3. |
