What is claimed is: 1. A tobacco product package device, comprising: a polymeric container having a bottom wall, a generally cylindrical side wall that extends in an axial direction from the bottom wall toward a connection rim, and a top opening that is at least partially defined by the connection
What is claimed is: 1. A tobacco product package device, comprising: a polymeric container having a bottom wall, a generally cylindrical side wall that extends in an axial direction from the bottom wall toward a connection rim, and a top opening that is at least partially defined by the connection rim, the polymeric container defining an interior space that is in communication with the top opening; a moist snuff tobacco product arranged in the interior space of the polymeric container; a metallic lid that releasably engages the polymeric container to enclose the moist snuff tobacco product in the interior space, the metallic lid including a lid wall that is integral with a skirt, wherein the skirt provides a snap-fit engagement with the connection rim; and a resilient gasket affixed to an interior surface of the lid wall to provide a moisture barrier and a non-hermetic seal between the metallic lid and the polymeric container when the metallic lid is releasably engaged with the polymeric container. 2. The device of claim 1, wherein the moisture barrier inhibits egress of moisture from the moist snuff tobacco product and out of the container. 3. The device of claim 1, wherein the non-hermetic seal permits venting of byproduct gases from the polymeric container when the metallic lid is releasably engaged with the polymeric container. 4. The device of claim 1, wherein the resilient gasket abuts with the connection rim of the polymeric container when the metallic lid is releasably engaged with the polymeric container. 5. The device of claim 1, wherein the container includes one or more vent structures formed proximate the connection rim, the vent structures providing a path for gas exchange between ambient air and the interface between the gasket and the container. 6. The device of claim 5, wherein the skirt of the lid comprises a continuous bead that mates with a discontinuous bead on the connection rim of the container to provide the snap-fit engagement. 7. The device of claim 1, wherein the resilient gasket comprises a ring of polymer material deposited directly onto a perimeter channel of the interior surface of the lid wall. 8. The device of claim 7, wherein the resilient gasket comprises a plastisol composition that is cured on the interior surface of the lid wall. 9. The device of claim 1, wherein the resilient gasket comprises a liner structure that is engaged with the interior surface of the lid wall using at least one of an adhesive and a locking bead. 10. The device of claim 9, wherein the liner structure comprises a polyethylene sheet material having a shape selected from a disc and a ring. 11. The device of claim 9, wherein the liner structure comprises indicia that communicates information viewable when the lid is separated from the container. 12. The device of claim 1, wherein the moist snuff tobacco product comprises an organic material that undergoes biological or chemical changes while stored in the container to create byproduct gases in the container. 13. The device of claim 12, wherein the resilient gasket provides the non-hermetic seal such that a portion of the byproduct gases arising from the biological or chemical changes of the organic material stored in the container exit from the container along a path bordered by the resilient gasket. 14. The device of claim 13, wherein the skirt of the lid comprises a bead that mates with a bead of the connection rim of the container to provide the snap-fit engagement that urges the gasket into abutting contact with the connection rim of the container. 15. The device of claim 1, further comprising a side label attached to outer circumferential surfaces of the container and lid. 16. The device of claim 1, wherein the gasket includes a ring-shaped structure arranged on the interior surface of the lid wall so as to abut against the connection rim of the container. 17. A tobacco product package device, comprising: a container defining an interior space and having a bottom wall, a generally cylindrical side wall that extends from the bottom wall toward a connection rim; a tobacco product for oral consumption arranged in the interior space of the container; a lid that encloses the tobacco product in the interior space of the container, the lid including a lid wall that is integral with a skirt, wherein the skirt is releasably engaged with the connection rim; and a resilient gasket in engagement with an interior surface of the lid wall to provide a moisture barrier and a non-hermetic seal between the lid and the container when the lid is secured to the container, the resilient gasket abutting with the connection rim of the container when the lid is secured to the container, wherein the moisture barrier inhibits the migration of moisture to and from the container when the lid is secured to the container, and wherein the non-hermetic seal permits gas exchange between ambient air and the interior space when the lid is secured to the container. 18. The device of claim 17, wherein the container includes one or more vent structures formed proximate the connection rim, the vent structures providing a path for gas exchange between ambient air and the interface between the gasket and the container. 19. The device of claim 18, wherein the resilient gasket comprises a ring of polymer material deposited directly onto a perimeter channel of the interior surface of the lid wall. 20. The device of claim 19, wherein the skirt of the lid comprises a continuous bead that mates with a discontinuous bead on the connection rim of the container to provide at least one of a snap-fit engagement and a slide-lock engagement. 21. The device of claim 17, wherein the tobacco product arranged in the interior space of the container comprises an organic product selected from the group consisting of chewing tobacco, moist snuff tobacco, and dry snuff tobacco. 22. The device of claim 21, wherein the resilient gasket provides the non-hermetic seal such that a portion of gases arising from biological or chemical changes of the organic product stored in the container exit from the container along a path bordered by the resilient gasket. 23. The device of claim 17, further comprising a side label attached to outer circumferential surfaces of the container and lid. 24. The device of claim 17, wherein the container comprises a polymer body and the lid comprises a metallic body, and wherein the metallic lid is press-fit into engagement with the polymer container so that a bead defined by the lid mates with a bead defined by the container to urge the lid wall toward the container. 25. The device of claim 17, wherein the non-hermetic seal permits venting of byproduct gases from the container while the lid is releasably engaged with the container. 26. The device of claim 17, wherein the gasket includes a ring-shaped structure arranged on the interior surface of the lid wall so as to abut against the connection rim of the container.
