A closure and container assembly biological sterility indicator having a container, a closure, test spores, growth and indicator media, and a frangible barrier for separating the growth medium from the test spores is shown. The closure is moveable in the container between open and closed positions.

A closure and container assembly biological sterility indicator having a container, a closure, test spores, growth and indicator media, and a frangible barrier for separating the growth medium from the test spores is shown. The closure is moveable in the container between open and closed positions. When in the open position, sterilant may flow into and out of the container via a tortuous pathway defined by the interior surface of the container or the exterior surface of the closure. The tortuous pathway may also include one or more openings in the wall of the closure. When the closure is in the closed position, the container is sealed. The sterility indicator may be assembled with the test spores impregnated on a spore strip which is placed in close proximity to the closure.

A closure and container assembly comprising a closure having a top and a depending sidewall, and a container having an interior surface and an opening for receiving the closure, wherein the closure is movable between two positions within the container such that when in the first position the container is sealed and when in the second position fluid communication exists between an environment outside of the container and the interior of the container via a tortuous pathway defined by at least one recess along the interior surface of the container or the exterior surface of the sidewall of the closure which tortuous pathway is constructed and arranged to cause at least two deflections of a fluid entering the container and to require that said fluid entering the container flow in a direction which forms an angle of 90°or less with an axis running through the center of said container, from said opening to the bottom of said container, to displace fluid in the container and is sized and shaped to accommodate a rapid rate of flow therethrough so that when tested to determine the flow resistance thereof, in a test wherein a hole is drilled in said bottom of said container and the hole is connected to a source of air, upon forcing air from the source of air through the container across the tortuous pathway, when the closure is in its second position and the assembly is placed in a tank of water at the bottom of a 20 cm column of water extending above the surface of the water in the tank, the air flowing across the tortuous pathway and into the column of water under 10 mm Hg pressure will displace a 90 ml, 14 cm column of water in a maximum time of 10 seconds.
