PROBLEM TO BE SOLVED: To provide a cup vessel sealing device which can prevent degradation of a product caused by oil leakage without providing any equipment for oil leakage prevention, and can be continuously disposed close to each other, or installed within an aseptic filling line without any limitation to the space or the cost in installing the device. SOLUTION: In the cup vessel sealing devices 10 and 11, a film for a lid placed on an opening flange of a vessel is pressed from above by a heating unit with a heater built therein against the cup vessels which are continuously carried after the vessels are filled with the content, and the film is heat-bonded to the opening flange part. The rotation of an electric motor 40 to be electrically controlled is transmitted to a screw shaft 51 of a ball screw mechanism 50 via rotation transmitting means 41, 42 and 43, and a base panels 20 and 30 to support heating units 21 and 31 are integrally fixed to a nut 52 of the ball screw mechanism 50 which is vertically reciprocated by the rotation of the screw shaft 51. |
