Abstract: A liner for use with a closure package and an associated container includes a pull tab that is crimped so that the tab remains in place during assembly of the closure package. The closure package includes a cap having a top wall portion and a depending skirt portion. The cap has an engaging element formed therein, that is engageable with an engaging portion of the container. The liner is formed of a laminate having a resilient material and an adhesive layer. The liner includes a central portion configured for placement in the cap abutting the top wall portion and a tab extending from the central portion. The tab is folded over so as to rest, at least in part, on the central portion. The tab and central portion define a hinge region which defines a hinge line at a juncture of the tab and the central portion. The hinge region has a deformation area formed therein, in at least two directions relative to the hinge line, to lock the tab in position resting, at least in part, on the central portion.
