  • Patent number: 10940225
    Abstract: Sterilization packaging systems with features for sealing a volume against an ingress of contaminants are provided. Such features include a sealing assembly including a gasket and a sheet of filter material. The sealing assembly seals a lid to a seal rim of a base. The gasket has an upper surface, outer edge, and inner edge. The upper surface of the gasket comprises a first row of alternating protrusions and indentations and a second row of alternating protrusions and indentations that define a channel therebetween. The sheet of filter material extends from an inner edge of the gasket. The gasket completely surrounds the sheet of filter material, wherein the indentations and channel facilitate delivery of a sterilization agent through the filter material. A sterilization assembly including a lid having a plurality of protrusions in its upper surface in conjunction with a gasket having a smooth upper surface is also provided.
