Title: VACUUM-SEALING DEVICE AND METHOD FOR OPERATING VACUUM-SEALING DEVICE
Abstract:
A vacuum-sealing device, provided with: an outer cylinder part (501B) having a distal end surface brought into contact in an airtight matter with the outer surface of a container so as to cover an exhaust hole of the container to be vacuum sealed; and a main body part (501A) provided in the outer cylinder part (501B) so as to be capable of advancing/retracting in the direction in which the axial center of the outer cylinder part (501B) extends. The vacuum-sealing device is also provided with: a driver (503) for causing the outer cylinder part (501B) and the main body part (501A) to advance/retract in the direction in which the axial center of the outer cylinder part (501B) extends; and a heater (504) for heating the distal end (51) of the main body part (501A). An exhaust space (58) in communication with the distal end surface of the outer cylinder part (501B) is formed between the external peripheral surface of the distal end (51) of the main body part (501A) and the internal peripheral surface of the outer cylinder part (501B).
