PURPOSE:To manually bond the cover of a pack with body by holding a joint piece at temperature difference of 5-50 deg.C in the pack joining in a super-store, applying a load to a film and thermally bonding for regulated bonding time. CONSTITUTION:Temperature control knobs 29, 30 are set so that upper and lower joining pieces 17, 7 are at temperature difference of 15-50 deg.C at the prescribed temperature in such a manner that the temperature of the piece 17 is 215-220 deg.C and the piece 7 is 170-175 deg.C, and controlled while detecting by sensors 16, 6. When a polystyrene vessel to be bonded is placed on the piece 7, a motor 23 is driven by the operation of a microswitch, the piece 17 is moved down to thermally bond. Thus, the pack of the cover can be manually effectively bonded thermally with the body in a super-store, and simply bonded by a bonding machine. |
