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 an outer 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 outer layer, and a plurality of relatively raised portions extending outwardly relative to the outer surface adjacent to respective fluid-flow apertures. A plurality of the relatively raised portions are engageable with the closure, define a substantially horizontal, tortuous fluid-flow path between the outer surface and the closure, and are in fluid communication with a plurality of fluid-flow apertures for venting gas flowing substantially vertically through the fluid-flow aperture(s) and, in turn, substantially horizontally between the outer surface and the closure. An inner layer defines a plurality of pores in fluid communication with a plurality of the fluid-flow apertures of the outer layer that substantially prevent the flow of liquid through the inner layer and allow the flow of gas from the interior of the device through the pores, into a plurality of the fluid-flow apertures and, in turn, through the substantially horizontal fluid-flow path and into the ambient atmosphere.
