PURPOSE:To facilitate the control of sealing performance by using a seal plug main body and a seal material as separated bodies and to perform the detachment of the seal plug main body from a bottle, by mounting the seal material to the port to be tightly stoppered of a container and shrinking the same under heating to temporarily seal the port to be tightly stoppered and subsequently seaming and screwing the seal plug main body and integrally bonding the seal material and the seal plug main body through a pressure-sensitive adhesive. CONSTITUTION:When the port of a bottle 12 is hermetically sealed by a seal plug, the port of the bottle 12 is gently covered with a seal material 11 and heated. The seal material 11 is shrunk by this heating and brought into close contact with the port of the bottle to temporarily seal said port. After temporary sealing is finished, a seal plug main body 10 is tightened into or screwed in the port of the bottle. Since the layer of a pressure-sensitive adhesive 14 is provided to the back surface of the seal plug main body 10 at this time, the surface of the seal material 11 presses the seal plug main body 10 as tightening and screwing advances, and the seal material 11 and the seal plug body 10 are bonded and integrated through the pressure-sensitive adhesive 14. When the tightly stoppered bottle 12 is opened, the seal plug main body 10 is detached from the port of the bottle and the seal material 11 can be also detached from the port of the bottle simultaneously in the state integrated with the seal plug main body 10. |
