A container closure includes a closure member defining container closing expanse, a tamper-indicating element in the closure interiorly of the closure member and tines movable with the closure member for both retaining the tamper-indicating element with the closure and for selectively tearing the tamper-indicating element. The movable tines are inaccessible through the closing expanse of the closure member and the closure affords visibility therethrough of the condition of the tamper-indicating element. The tamper indicating element includes a compressible foam layer and the movable tines reside essentially in the foam layer.

A container closure having a closure member defining container closing expanse, means in said closure interiorly of said closure member for providing tamper indication and means dependent from said closure member and movable with said closure member for both retaining said tamper indication means with said closure and for selectively rupturing said tamper indication means, such movable means being inaccessible through said closing expanse of said closure member and said closure affording visibility exteriorly thereof of said tamper indication means, such tamper indication means including a compressible layer, said movable means having a first extent adjacent said closure member and a second extent distal from said closure member, said second closure member extent being enlarged with respect to said first closure member extent and being in retentive residence within said compressible layer. A method of providing a tamper-indicating closure of type including a closure member for first sense movement relative to a container into securement therewith and in circumscribing relation to a container access opening and for second sense movement for release from such securement, said method comprising the steps of: (a) disposing a retaining member interiorly of said closure member and restraining said retaining member for travel with said closure member; (b) forming a secured assembly of a tamper-indicating element and a compressible layer; and (c) applying a backing member to said assembly and forcing said assembly into such closure member interior and onto said retaining member, said backing member being selected such that, in the resulting closure, the retaining member is deformed and thereby retentively captured by said compressible layer.
