Abstract
An elastomeric stopper for a fluid-containing bottle to hermetically seal the content therein and to provide access thereto by the insertion of an infusion device through the stopper, the stopper comprising an annular protuberance which forms a second seal with the shaft of the infusion device to prevent leakage, blow-out and introduction of particulate matter into the bottle.
