Abstract
A sterilization container for sterilizing medical instruments that includes a body defining an interior volume and a lid connected to the body and configured to seal the interior volume between the lid and the body. The lid includes an exterior filter structure including a first plurality of ridges and a first plurality of troughs formed between the first ridges. The container includes a filter assembly connected to the lid and including an interior filter structure including a second plurality of ridges and a second plurality of troughs formed between the second ridges. The first plurality of ridges of the exterior filter structure are interposed between the second plurality of ridges of the interior filter structure. The exterior and interior filter structures are configured to form longitudinal channels positioned between the lid and filter assembly to define a rectangular tortuous filter path that inhibits ingress and egress from the interior volume.
