Hollow flexible sealing member for environmental sealing

摘要

The hollow sealing member 1 having flexibility can be inflated through a hole 8 formed in the wall of the sealing member to seal the first article 3. The hollow sealing member 1 comprises a first sealing member 10 located on the inner facing surface of the wall 4, and a wall 4 immediately adjacent to the hole 8 while deforming the first sealing member 10. A separation holding means 18 for maintaining separation between the external facing surface of the first article 3 and the first article 3. The first sealing member 10 may be modified to block the hole 8 by the pressure in the hollow sealing member 1 when the hollow sealing member expands.
