A closure for a container wherein the container has an open end and a closed end with a crimp or the like at an uppermost edge of said open end, the closure being configured to engage the open end of the container, wherein the closure comprises: a collar configured to engage the container; a lid connected to the collar by at least one hinge; wherein to facilitate engagement the collar is configured to extend over and surround the open end of the container such that an inner surface impinges on, or is immediately adjacent to, an outer surface of the open end of the container; a plurality of beads (6,7) extend outwardly from the inner surface of the collar to fixedly hold the collar in engagement with the container, wherein said beads are located substantially uniformly relative to each other and occupy less than 50% of the inner surface of the collar; and wherein the beads in the same plane are of the same shape, wherein a plurality of vertical or substantially vertical ribs are provided extending from the inner surface of the collar, and wherein the collar is provided with a rim at the uppermost part thereof which is spaced apart from the inner surface of the collar, characterised in that: the beads are located in two adjacent planes, wherein the beads in each plane are located uniformly to each other and are offset with the location of the beads in the adjacent plane; and wherein the beads are provided in one of two shapes to define primary beads and secondary beads; and wherein primary beads and secondary beads have a general shape defined by a lowermost part that is shallow and extends away from the inner surface of the collar in at least one of a curved, sloped, linearly or substantially linearly or a combination thereof before arriving at a lip (8,9), and wherein each of said lips (8,9) are in the same or substantially the same radial plane; and wherein the lips extend from the inner surface substantially perpendicular; and wherein the lips of the primary beads and secondary beads are in the same radial plane to collectively engage the crimp; and wherein said ribs support the rim, said ribs being sized to provide an abutment means to limit the travel of the container into the collar. a collar configured to engage the container; a lid connected to the collar by at least one hinge;
