摘要： The invention relates to a novel type of ring seal for flange connections of pipes in which the ring seal can also be made of the material of the flanges. Said novel type of expansion seal comprises a wedge-shaped indent around the external edge thereof. Said indent has legs that are Y-shaped from a cross-sectional view. When the Y-shaped legs are compressed, pressure is applied to the vertical internal walls of radial depressions of the flanges that are to be connected, said pressure allowing a practically absolute sealing effect also against helium and hydrogen. The invention further relates to a gas-tight and taste-neutral bottle closure that is based on the novel system and is used especially for wine and champagne bottles.
