SEALING DEVICE

PROBLEM TO BE SOLVED: To realize the automatic feeding of ink to a sealing device and its feeding by exact amount. SOLUTION: An impregnating roller 2, a first transfer roller 6, a second transfer roller 10 and a printing holder 14 are respectively mounted to upright rotating shafts 4, 8, 12 and 26 and rotated. Respective rollers 2, 6, 10 and 14 come into contact with one another successively and rotated so as to transfer the ink fed to the impregnating roller 2 to the first transfer roller 6 and the ink of the first transfer roller 6 is transferred to the second transfer roller 10. Further, the ink is fed to the protrusion face (the surface of a printing type 16) of the printing holder 14 so as to be sealed to a label before its pasting to a container. In addition, a discharge gun 38 for jetting the ink against the impregnating roller 2 is provided. The discharge gun 38 blasts the ink against the nearly same height as that of the protrusion face (the printing type) 16 of the printing holder 14 at a position B just before the contacting position A between the impregnating roller 2 and the first transfer roller 6 or the height a little higher than that of the protrusion face 16.
