A two-part closure (1) which has a disc (2) and a skirt (3). In one example, the skirt wall is smooth between upper and lower rims so that the disc is moveable between the rim features. Typically in a metal skirt or ring, the upper rim feature is a curl (11) and the lower rim feature is a curled edge (12) with equi-spaced lugs (13) on the skirt wall.

1. A reclosable two-part closure configured to be removably fastened to a container having threads, the closure comprising: a metal disc and a metal skirt coupled to the metal disc, the metal disc having a seal and a surrounding rim and is held within the skirt moveably between an inwardly projecting rim at an upper end of the skirt and a lower skirt rim defined by either an annular inward projection on a wall of the skirt or lugs at a lower end of the skirt, wherein a sum of a first distance measured from the seal to a contact point of the disc rim and lower skirt rim along a first direction and an effective thickness of the annular inward projection or lugs measured along the first direction is greater than a second distance measured from the top of the threads on the container to a top of the container along the first direction, the first distance being greater than the effective thickness. 2. A closure according to claim 1, in which the upper end of the metal skirt is lower than a top of the metal disc. 3. A closure according to claim 1, in which the metal from which the metal disc is formed is a single piece of decorated metal. 4. A closure according to claim 1, in which the metal is steel having a thickness, which is less than that used for manufacturing vacuum twist closures of the same diameter. 5. A closure according to claim 1, in which the inwardly projecting rim on the top of the metal skirt includes a first inward curl and the lower end of the metal skirt includes a second inward curl. 6. A closure according to claim 5, in which the rim of the metal disc is curled inwardly. 7. A closure according to claim 5, in which the first and second inward curls have a radius of curvature of no less than 0.4 mm. 8. A closure according to claim 1, in which the inwardly projecting rim on the upper end of the metal skirt is discontinuous, so that inwardly projecting rim portions are only provided where there is no lug opposite. 9. A closure according to claim 1, in which the upper end of the metal skirt is higher than a top of the metal disc. 10. A closure according to claim 5, in which the rim of the metal disc is curled outwardly. 11. A closure according to claim 5, in which the rim of the metal disc includes sealing material. 12. A reclosable closure adapted for use with a container having a neck that defines both a top finish and a container projection with a top surface configured to contact the closure at a contact point such that a first axial distance measured along a first direction from the contact point to the top finish is defined, the closure comprising: a disc having an outer rim that defines a lower most point of the disc, and a seal disposed within the rim, the seal having a lower surface configured to compress against the top finish of the container, such that a second axial distance measured along the first direction from the lower most point of the disc to an upper most point of the lower surface of the seal is defined; anda skirt coupled to the disc, the skirt having: a wall with a top end and an opposing bottom end;a first inward projection at the top end of the wall; andat least two lugs or inward projections at the bottom end of the wall, the at least two lugs or inward projections each having a height that defines a third axial distance along the first direction;wherein the first axial distance is less than a sum of the second axial distance and the third axial distance. 13. The reclosable closure of claim 12, wherein, when the seal is compressed against the top finish of the container, the upper most point of the lower surface of the seal is defined, and the second axial distance is measured from the lower most point of the disc to the upper most point of the lower surface of the seal. 14. The reclosable closure of claim 12, wherein the disc is moveably held between the first inward projection at the top end of the wall and the at least two lugs or inward projections at the bottom end of the wall. 15. The reclosable closure of claim 12, wherein the at least two lugs or inward projections are annular projections. 16. The reclosable closure of claim 12, wherein the first inward projection includes a first inward curl and the at least two lugs or inward projections includes a second inward curl. 17. A container and closure combination comprising: a container that has a top finish and a container projection below the top finish and defining a top surface;a reclosable closure configured to contact the top surface of the container projection at a contact point, such that a first axial distance measured along a first direction from the contact point to the top finish is defined;a disc having an outer rim that defines a lower most point of the disc, and a seal disposed within the outer rim, the seal having a lower surface configured to compress against the top finish of the container, such that a second axial distance measured along the first direction from the lower most point of the disc to an upper most point of the lower surface of the seal after the seal has been compressed against the top finish; anda skirt coupled to the disc, the skirt having a wall with a top end and an opposing bottom end;a first inward projection at the top end of the wall; anda second inward projection at the bottom end of the wall, the second inward projection having a height that defines a third axial distance along the first direction;wherein the first axial distance is less than a sum of the second axial distance and the third axial distance and the second axial distance is greater than the third axial distance. 18. The container and closure combination of claim 17, wherein the disc is moveably held between the first inward projection at the top end of the wall and the second inward projection at the bottom end of the wall. 19.
