A package, comprising: a tobacco-containing material; a container, comprising: a body portion defining an internal space accessible via an opening and in which the tobacco-containing material is received, the body portion including a rib structure comprising a plurality of rib segments arranged in spaced relation around the periphery of a side wall of the body portion, each rib segment being separated from an adjacent rib segment by a vent channel; a cover configured to engage the body portion so as to cover the opening and substantially enclose the internal space; a valve assembly in fluid communication with the internal space and configured to relieve pressure from the atmosphere within the internal space of the container; a barrier film coupled to the container and covering the opening to the body portion, wherein the valve assembly is engaged with the barrier film; and a protective barrier that separates the tobacco-containing material from the valve assembly; wherein a secondary space is defined between the barrier film and the cover when the cover is engaged with the body portion, the valve assembly being configured to vent from the internal space into the secondary space; wherein the vent channels are configured to vent the secondary space to an external environment when the cover is engaged with the body portion; and wherein the valve assembly is configurable between a closed configuration and an open configuration, the valve assembly being configured to remain in the closed configuration until the pressure from the atmosphere within the internal space of the container is equal to an opening pressure at which point the valve assembly is configured to momentarily open to the open configuration to relieve the pressure and then return to the closed configuration. a tobacco-containing material;
