PROBLEM TO BE SOLVED: To provide a packaging/filling device which can realize excellent sealing with ultrasonic sealing.SOLUTION: A packaging/filling device which fills a band-like packaging material with a fluid food to form a packaging container storing the fluid food comprises a seal device including: an ultrasonic supply unit for supplying an ultrasonic wave; and an anvil being a reception jig, holding the band-like packaging material between the ultrasonic supply surface of the ultrasonic supply unit and the reception surface of the anvil, applying the ultrasonic wave to the held band-like packaging material and sealing the band-like packaging material. The reception surface of the anvil has a smooth shape with no sharp-cornered portion in a region adjacent to a contact part brought into contact with the band-like packaging material at the time of sealing.SELECTED DRAWING: Figure 4 |
