PURPOSE:To improve a corrosion resistance and to shorten correcting time by heating at the specified temp. together with pressing a tape-shaped resin to the inner side of the weld zone of a can body, then by releasing the press after cooling with maintaining the press condition. CONSTITUTION:A mandrel 16 is arranged inside a can body 12 and a presser body 20 outside thereof, and a tape-shaped resin 10 is pressed to the inner part of a weld zone 14 by the elastic part 18 of the weld zone 14. A high frequency heating coil 26 is incorporated in the presser 20, which heats with induction the weld zone 14. The tape-shaped resin 10 and weld zone 14 are pressed by adequate pressure with the elastic bodies 18 and 20 of the mandrel 16 and the resin 10 is heated to the temp. of >=+20 deg.C with operating the heating coil 26. The resin 10 is then cooled by

PROBLEM TO BE SOLVED: To provide a packaging unit providing a suitable interaction between half-shell members and a packaging material. SOLUTION: The packaging unit includes chain conveyers each having a plurality of jaws and a plurality of counter jaws, and the jaws and the counter jaws cooperate with each other to seal a tube using heating members mounted to the jaws. The conveyers are provided with half shell members 38 for controlling the capacity of a package. The half-shell members 38 are individually mounted to the jaws and the counter jaws whose movement contacting with and separating from the tube is controlled by guide means. The guide means have respective cams 44 for the chain conveyers and cam followers 42 mounted to the half-shell members are engaged with the cams 44, so that operations of the half-shell members are controlled. The cams 44 have adjustment devices to adjust distances between the cams 44, thereby adjusting the capacity of the formed package. COPYRIGHT: (C)2010,JPO&INPIT
