PROBLEM TO BE SOLVED: To obtain a duct which can be repetitively used, take out contents from an arbitrary position without splashing and seal remaining contents in a container for preservation by attaching a blade in one of cylinder ports, providing a suction part to the container around the cylinder port and providing an intake chamber and a valve in the middle of a tube. SOLUTION: A blade is attached in one of cylinder ports of a duct, while a suction-disk-like suction part 2 is provided around the cylinder port and an intake chamber 3 and a valve 4 are provided in the middle of a tube. Parts except the blade 1 are formed of an elastic material. While air in the intake chamber 3 is discharged, an outer periphery of the suction part 2 is brought into contact with an arbitrary position of a film container, and then pressure to the intake chamber 3 is released to fix the duct to the film. Further sucking the film into the tube brings the film into contact with the blade 1 to have it broken, and contents flow into the duct. With the valve 4 opened, the contents flow outside, and when the valve 4 is returned to a closed state again, the container is sealed. |
