Claim:
1. A venting liner connectable in fluid communication between a closure and an interior of a device for venting gas from the interior of the device into an ambient atmosphere, the venting liner comprising: a first substantially liquid impermeable and gas permeable non-perforated outer layer connectable in fluid communication with an interior of a device for allowing a flow of gas but preventing a flow of liquid therethrough; a second non-perforated outer layer defining a plurality of fluid flow paths therethrough and substantially incompressible in response to application of a closure force applied by a closure thereto; and a compressible inner layer that is compressible in response to application of a closure force applied by a closure thereto, and defining a plurality of inner fluid flow paths in fluid communication between the first outer layer and the second outer layer for allowing venting of gas from the interior of a device, through the first outer layer, through the compressible inner layer and, in turn, through the second outer layer and into the ambient atmosphere.
