Seal for filtered vent in a sterilization container
First Claim
1. An arrangement for providing a sealed filtered vent for a sterilization container having a vent area formed by a plurality of holes passing through at least one of:
- a wall or a lid of the sterilization container, the vent area surrounded by a convex ridge on an outside surface of the wall or lid and a concave recess on an opposing inside surface, the arrangement comprising;
a filter, sized and adapted to cover the vent area and overlie the concave recess;
a filter cover plate, being of a generally planar nature with a vent area formed by a plurality of holes passing through the filter cover plate the vent area surrounded by a convex ridge, the convex ridge sized and adapted to correspond to the concave recess of the sterilization container;
a gasket, secured to the filter cover plate along at least the convex ridge, the gasket having an outwardly-facing surface with at least two ridges that extend radially outwardly therefrom; and
a means for mounting and securing the filter cover plate over the vent area on the wall or lid of the sterilization container, with the filter interposed and secured between the filter cover plate and the vent area on the inside surface of the wall or lid.

Abstract
A container (10) used for sterilizing medical instruments and the like has a sealed filtered vent. A wall or a lid of the container has a vent area formed by a plurality of holes (12) that pass therethrough. The vent area is surrounded by a convex ridge (16) on an outside surface of the container, with a corresponding concave recess (26) on an opposing inside surface. A web of filter material (36) is sized and adapted to cover the vent area and overlie the concave recess. A cover plate (37) is generally planar, with a vent area formed by a plurality of holes (38) that pass through the cover plate. This vent area is surrounded by a convex ridge (43) that is sized and adapted to correspond to the concave recess of the sterilization container. An elastomeric gasket (127) with outwardly-projecting ridges is secured to at least the convex ridge of the cover plate. A means for mounting the cover plate over the vent area of the container secures the filter material between the container vent area and the cover plate.
