A film sealing mechanism which, for a tube-shaped film in which holds content and has been disposed so as to be sent from a film port downward by way of a sending means, is provided with a heater and a heater-receiving part which are disposed facing each other in an orientation orthogonal to the position of the sending means and which are disposed so as to be capable of sandwiching the outer surface of the film, said film sealing mechanism being provided with a fixed bracket and a moving bracket which are disposed so as to face each other, wherein: the fixed bracket comprises the heater and two film parallel guides which sandwich the heater from above and below; and the moving bracket comprises the heater-receiving part and either a film guide which is formed on the front surface of the heater-receiving part itself or parallel film guides which are disposed so as to sandwich the heater-receiving part from above and below. The film guide of the fixed bracket comprises a first wing-shaped part having a shape in which an outer edge, which obliquely abuts both side-surfaces of the tube-shaped film which are substantially on the left and right as seen from a plan view thereof, is expanded toward the moving bracket-side; and the film guide of the moving bracket comprises a second wing-shaped part having a shape in which an outer edge, which obliquely abuts both side-surfaces of the tube-shaped film which are substantially on the left and right as seen from a plan view plane thereof, is expanded toward the fixed bracket-side. |
