A closure ( ) for mounting onto a container ( ), the closure ( ) including a top portion ( ) and a skirt portion ( ) depending from the top portion ( ). An annular sealing rib ( ) projects downwardly from an underside of the top portion ( ). The rib ( ) includes a first portion ( ) which is contiguous with the top portion ( ) and has an inner surface ( ) which lies radially inwardly of the skirt portion ( ) and at least a second, frusto-conical, portion ( ) contiguous with the first portion ( ) and separated from the top portion ( ) by the inner surface ( ) of the first portion ( ). The second portion ( ) has an upper side and an underside and extends radially inwardly to a circular edge. The inner surface ( ) of the first portion ( ) has an internal diameter relative to the external diameter of the end portion ( ) of the container ( ) to which the closure is to be attached such that during attachment of the closure with the end portion of the container, the sealing rib ( ) is engaged by the end portion of the container so folding the second portion ( ) at least towards the inner surface ( ) of the first portion ( ) of the rib to form a seal between at least an outer surface of the end portion of the container and the closure. The closure further has an annular protrusion ( ) formed on the underside of the second portion ( ) which extends outwardly therefrom. The protrusion ( ), on attachment of the closure with the end portion, engages the outer surface of the end portion ( ) so causing the sealing rib ( ) to be disposed over a greater area of the outer surface of the end portion of the container.
