A venting liner is connectable in fluid communication between a closure and an interior of a device for venting gas from the interior into the ambient atmosphere. The venting liner has a first fluid impervious and gas permeable outer layer, a second relatively rigid and substantially incompressible outer layer defining an open cell structure, and an inner foam layer defining an inner surface and an outer surface, a plurality of fluid-flow apertures spaced relative to each other, extending between the inner and outer surfaces, and forming substantially vertical fluid-flow paths through the inner layer. The first outer layer is in fluid communication with the interior of the device for venting gas through the interior of the first outer layer, substantially vertically through the apertures and, in turn, through the interior open cell structure of the second outer layer and into the ambient atmosphere.
