A closure that includes a top panel and a skirt extending downwardly from a peripheral edge of the top panel is provided. The skirt terminates in a plurality of spaced thread engagement flanges for engaging the thread of the neck of a container. The closure includes a polymer-filled channel which connects the top panel to the skirt. When engaged with the threaded neck of a container, the neck is forced into the channel and engaged by the polymer so that the channel and polymer provide lateral rigidity to the neck. This rigidity prevents the neck from deflecting from the forces resulting between the threads and thread engagement lugs when the forces therebetween are increased to the level required to adequately seal the closure to the container.

1. A metal closure comprising: a circular, closure panel having an internal surface extending to a periphery;a concentric channel extending from the periphery along an angled wall into a parallel wall generally parallel to the closure panel, the parallel wall extending into a first rounded wall having a center of radius within the closure, wherein the parallel wall is offset from the closure panel by a first distance;a concentric flange extending from the first rounded wall into a second rounded wall having a center of radius external to the closure into a transition wall which extends into a third rounded wall having a center of radius within the closure, wherein the first rounded wall transitions into the second rounded wall at a second distance from the periphery, the second distance being at least 2 times as large as the first distance;a cylindrical skirt extending from the concentric flange;at least 4 equally spaced rolled flanges extending from the cylindrical skirt;at least one thread engagement flange located between each pair of rolled flanges; anda resilient polymeric material which fills the concentric channel. 2. The closure of claim 1, wherein the radii of the first and second rounded walls are smaller than the radius of the third rounded wall. 3. The closure of claim 2, wherein an angle between the angled wall and the parallel wall is between 20 and 75 degrees. 4. The closure of claim 3, including 5 rolled flanges and 5 thread engagement flanges. 5. The closure of claim 4, wherein the closure panel has a centrally located vacuum indicating panel which includes a circular center portion, a first annular portion, and a second annular portion configured to permit the circular center portion to move relative to the closure panel in response to pressure variations within an associated container. 6. The closure of claim 5, wherein a radius of each of the rolled flanges is smaller than the radius of the third rounded wall. 7. The closure of claim 6, wherein the transition wall is generally parallel to the closure panel and the parallel wall, and a plane passing through the transition wall is displaced further from the parallel wall than the closure panel. 8. The closure of claim 7, wherein the engagement flanges include a tapered, rolled tip which facilitates sliding of the engagement flanges relative to a thread on a respective container neck. 9. The closure of claim 8, wherein the polymeric material is a plastisol liner. 10. A metal closure comprising: a circular, closure panel having an internal surface extending to a periphery, wherein a vacuum indicating panel is located at the center of the internal surface;a concentric channel extending from the periphery along an angled wall into a parallel wall generally parallel to the closure panel, the parallel wall extending into a first rounded wall having a center of radius within the closure, wherein the parallel wall is offset from the closure panel by a first distance;a concentric flange extending from the first rounded wall into a second rounded wall having a center of radius external to the closure into a transition wall which extends into a third rounded wall having a center of radius within the closure, wherein the first rounded wall transitions into the second rounded wall at a second distance from the periphery, the second distance being at least 2 times as large as the first distance, the radii of the first and second rounded walls are smaller than the radius of the third rounded wall, an angle between the angled wall and the parallel wall is between 20 and 75 degrees, the transition wall is generally parallel to the closure panel and the parallel wall, and a plane passing through the transition wall is displaced further from the parallel wall than the closure panel;a cylindrical skirt extending from the concentric flange;at least 4 equally spaced rolled flanges extending from the cylindrical skirt;at least one thread engagement flange located between each pair of rolled flanges wherein the engagement flanges include a tapered, rolled tip which facilitates sliding of the engagement flanges relative to a thread on a respective container neck; anda resilient polymeric material which fills the concentric channel. 11. The closure of claim 10, including 5 rolled flanges and 5 thread engagement flanges. 12. The closure of claim 10, wherein the vacuum indicating panel includes a circular center portion, a first annular portion, and a second annular portion configured to permit the circular center portion to move relative to the closure panel in response to pressure variations within an associated container. 13. The closure of claim 10, wherein a radius of each of the rolled flanges is smaller than the radius of the third rounded wall. 14. The closure of claim 10, wherein the polymeric material is a plastisol liner. 15. The closure of claim 10, wherein when the closure is fabricated, the resilient polymeric material is in liquid form. 16. A sealed container comprising: a plastic container including a threaded neck which provides an opening to the container, the neck including generally parallel internal and external walls terminating at a sealing edge; anda metal closure including;a circular, closure panel having an internal surface extending to a periphery, wherein a vacuum indicating panel is located at the center of the internal surface,a concentric channel extending from the periphery along an angled wall into a parallel wall generally parallel to the closure panel, the parallel wall extending into a first rounded wall having a center of radius within the closure, wherein the parallel wall is offset from the closure panel by a first distance,a concentric flange extending from the first rounded wall into a second rounded wall having a center of radius external to the closure into a transition wall which extends into a third rounded wall having a center of radius within the closure, wherein the first rounded wall transitions into the second rounded wall at a second distance from the periphery, the second distance being at least 2 times as large as the first distance, the radii of the first and second rounded walls are smaller than the radius of the third rounded wall, the transition wall is generally parallel to the closure panel and the parallel wall, and a plane passing through the transition wall is displaced further from the parallel wall than the closure panel,a cylindrical skirt extending from the concentric flange,at least 4 equally spaced rolled flanges extending from the cylindrical skirt,at least one thread engagement flange located between each pair of rolled flanges wherein the engagement flanges include a tapered, rolled tip which facilitates sliding of the engagement flanges relative to a thread on the threaded neck, anda resilient polymeric material which fills the concentric channel;wherein the tapered, rolled tips are engaged with the threaded neck so that the sealing edge is forced into the polymeric material so that the polymeric material engages the sealing edge to resist deformation of the threaded neck when forces between the tips and threaded neck are sufficient to seal the closure to the threaded neck. 17. The container of claim 16, wherein the polymeric material is deformed to move between the external wall and the first rounded wall. 18. The container of claim 16, wherein an angle between the angled wall and the parallel wall is between 20 and 75 degrees. 19. The container of claim 17, wherein the polymeric material is deformed to move between the internal wall and the angled wall. 20. The container of claim 19, wherein the closure includes 5 rolled flanges and 5 thread engagement flanges. 21. The closure of claim 1, wherein the closure has an exterior, wherein at least a portion of the exterior thereof is coated with a soft-touch coating.
