There is provided a double rib overcap with a plug for a container with a removable membrane. The skirt of the overcap includes two inside surfaces axially separated a rib. The container opening is encircled by a rim and the membrane covers the opening such that the membrane extends radially onto an outer surface of the rim. The two inside surfaces of the skirt are dimensionally sized to create an interference-fit with the rim when the overcap is connected to the container when the membrane is either attached or removed. The overcap also includes a circumferential ring radially inward of the skirt that is axially positioned to engage the top surface of the membrane when the membrane is attached to the container and is diametrically dimensioned to engage an inner wall of the container when the membrane is removed from the container.

An interference-fit overcap according to claim 1, wherein the radially outwardly protruding rim encircling the container defines an outer surface and the membrane extends radially outward onto the outer surface of the rim. 3. An interference-fit overcap according to claim 1, wherein the radially outwardly protruding rim encircling the container defines an outer surface and the membrane covers the container opening without extending radially outward onto the outer surface of the rim. 4. An interference-fit overcap according to claim 1, wherein the first rib and the second rib each defines an uninterrupted circumferential rib. 5. An interference-fit overcap according to claim 1, wherein the first rib and the second rib each defines a plurality of circumferentially spaced portions. 6. An interference-fit overcap according to claim 1, wherein the skirt extends substantially perpendicular to the top panel of the overcap. 7. An interference-fit overcap according to claim 1, wherein the first rib and the second rib of the overcap each define a rounded edge portion at a radially inward surface opposite the outside surface of the skirt. 8. An interference-fit overcap according to claim 7, wherein the rounded edge portion of the first rib defines an inside diameter relatively larger than an inside diameter of the rounded edge portion of the second rib. 9. An interference-fit overcap according to claim 1, wherein the overcap is a thermoplastic material. 10. A container, comprising: a container body formed by a wall, wherein the wall defines an opening encircled by a radially outwardly protruding rim;a removably attached membrane substantially covering the opening while the membrane is attached; andan interference-fit overcap, comprising: a top panel having a periphery;a skirt extending from the periphery of the top panel to a distal end such that the skirt defines a first inside surface axially spaced from the top panel proximate the distal end of the skirt and defines a second inside surface axially positioned between the first inside surface and the top panel, wherein the first inside surface is diametrically dimensioned to produce an interference-fit with the membrane and rim and the second inside surface is diametrically dimensioned to produce an interference-fit with the rim alone;a first rib projecting inwardly from the skirt and axially located between the first inside surface of the skirt and the distal end of the skirt;a second rib projecting inwardly from the skirt and axially located between the second inside surface and the first inside surface; anda circumferential ring extending from the top panel in a same direction as the skirt extends and radially inward of the skirt, wherein the circumferential ring defines an outside surface on a radially outermost portion of the circumferential ring;wherein the first rib engages beneath the rim of the container to resist detachment of the overcap when the membrane is attached and the second rib engages beneath the rim of the container to resist detachment of the overcap when the membrane is not attached;wherein the outside surface of the circumferential ring is diametrically dimensioned to produce an interference-fit with the inner wall of the container when the second rib engages beneath the rim of the container, and wherein the circumferential ring comprises a distal surface opposite the top panel and axially positioned to engage the membrane when the first rib engages beneath the rim of the container, such engagement of the circumferential ring with the membrane providing resistance to downward movement of the skirt that would cause the second rib to engage beneath the rim of the container. 11. A container according to claim 10, wherein the radially outwardly protruding rim encircling the container defines an outer surface and the membrane extends radially outward onto the outer surface of the rim. 12. A container according to claim 10, wherein the radially outwardly protruding rim encircling the container defines an outer surface and the membrane covers the container opening without extending radially outward onto the outer surface of the rim. 13. A container according to claim 10, wherein the outwardly protruding rim is an outwardly rolled bead. 14. A container according to claim 10, wherein the first rib and the second rib each defines an uninterrupted circumferential rib. 15. A container according to claim 10, wherein the first rib and the second rib each defines a plurality of circumferentially spaced portions. 16. A container according to claim 10, wherein the skirt extends substantially perpendicular to the top panel of the overcap. 17. A container according to claim 10, wherein the first rib and the second rib of the overcap each define a rounded edge portion at a radially inward surface opposite the outside surface of the skirt. 18. A container according to claim 17, wherein the rounded edge portion of the first rib defines an inside diameter relatively larger than an inside diameter of the rounded edge portion of the second rib. 19. A container according to claim 10, wherein the membrane defines a thickness and the inside diameter of the first inside surface is approximately equivalent to a combined distance of the inside diameter of the second inside surface and twice the thickness of the membrane. 20. A container according to claim 10, wherein the membrane is a metal foil. 21. A container according to claim 10, wherein the overcap is a thermoplastic material. 22. A sealable storage device, comprising: a container, comprising: a body formed by a wall,an opening defined by the wall, andan outwardly rolled bead encircling the opening of the container, wherein the bead protrudes generally outward from the wall and defines an outer surface;a membrane removably attached to the bead such that the membrane substantially covers the opening and extends radially outward onto the outer surface of the bead while the membrane is attached; andan interference-fit overcap, comprising: a top panel having a periphery;a skirt extending from the periphery of the top panel to a distal end such that the skirt defines a first inside surface axially spaced from the top panel proximate the distal end of the skirt and defines a second inside surface axially positioned between the first inside surface and the top panel, wherein the first inside surface is diametrically dimensioned to produce an interference-fit with the membrane and bead and the second inside surface is diametrically dimensioned to produce an interference-fit with the bead alone;a first rib projecting inwardly from the skirt and axially located between the first inside surface of the skirt and the distal end of the skirt;a second rib projecting inwardly from the skirt and axially located between the second inside surface and the first inside surface; anda circumferential ring extending from the top panel in a same direction as the skirt extends and radially inward of the skirt, wherein the circumferential ring defines an outside surface on a radially outermost portion of the circumferential ring;wherein the first rib engages beneath the bead of the container to resist detachment of the overcap when the membrane is attached and the second rib engages beneath the bead of the container to resist detachment of the overcap when the membrane is not attached;wherein the outside surface of the circumferential ring is diametrically dimensioned to produce an interference-fit with the inner wall of the container when the second rib engages beneath the rim of the container, and wherein the circumferential ring comprises a distal surface opposite the top panel and axially positioned to engage the membrane when the first rib engages beneath the rim of the container, such engagement of the circumferential ring with the membrane providing resistance to downward movement of the skirt that would cause the second rib to engage beneath the rim of the container.
