Flexible, resilient anti-contamination baffle

摘要

A flexible, resilient anti-contamination baffle having a plurality of interleaved sheets of material. The sheets of material are secured at one end thereof to a surface adjacent an opening to be sealed and have the capability of not only substantially preventing the passage of gaseous contaminants through the opening when the regions adjacent the openings are of substantially the same pressures but also capable of allowing the rapid venting of gases from a region of higher pressure to a region of lower pressure. Additionally, the sheets of material are formed so as to provide a "breakaway capability" allowing the passing of an object through the opening without encompassing or entangling the object as it passes therethrough.
