DEFINITION

Classification: 55/361

(under the class definition) Apparatus having a separating member comprised of nonrigid cohesive material of essentially globular, tubular, or cylindrical container configuration which encloses a space and has at least one opening for passing gas into or out of said member, said member comprised in part or entirely of gas permeable filter material.

(1) Note. In use position the bag is capable of being flexed by reason that the material is not rigidly nor inflexibly supported or sustained against such action as by being held sandwich style.
