Abstract

Abstract A container closure providing tamper indication includes tines therein in engagement with a tamper-indicating assembly which is nested in the closure and retained therein by the tines up to the point of telltale activation on container opening. The closure includes a member adapted to engage the tamper-indicating assembly subsequent to telltale activation both to remove the assembly from secured relation to a container and to retain the assembly with the closure in the course of its removal from the container and reapplication thereto.

Claim 3
Dependent Claim 27 words
The closure claimed in claim 1 wherein said first means comprises at least one retaining-rupturing member extending from said closure member into engagement with said indicating element.
Claim 4
Dependent Claim 45 words
The closure claimed in claim 2 wherein said closure member includes a top panel and a threaded skirt depending therefrom, said retaining-rupturing member extending downwardly from said top panel, said second means being situated upwardly of such skirt threads and downwardly of said retaining-rupturing member.
Claim 5
Dependent Claim 21 words
The closure claimed in claim 1 wherein both said first means and said second means are integral with said closure member.
Claim 6
Dependent Claim 220 words
A tamper-indicating container comprising: (a) a vessel for article containment and having an access opening; (b) a see-through closure member for first sense movement relative to said vessel into securement therewith and in circumscribing relation to said access opening and for second opposite sense movement for release from such securement; (c) first and second means disposed interiorly of said closure member for travel with said closure member; and (d) indicating means in captive relation to said first means for movement therewith during said closure member first sense movement into securement with said vessel across said access opening, said first means tearing said indicating means in the course of said closure member second sense movement to provide such tamper indication, said second means engaging said indicting means following such tearing thereof and releasing said indicating means from said securement thereof with said vessel, said tamper-indicating element comprising a rupturable and tearable layer, said first means being secured in said rupturable and tearable layer, a stiffening layer juxtaposed with said rupturable and tearable layer, and a telltale layer juxtaposed with said stiffening layer and exposed therethrough upon tearing of said rupturable and tearable layer by said first means, and a container sealing layer juxtaposed with said telltale layer, said second means being disposed in spaced confronting relation to said container sealing layer.
Claim 7
Dependent Claim 220 words
A tamper-indicating container comprising: (a) a vessel for article containment and having an access opening; (b) a see-through closure member for first sense movement relative to said vessel into securement therewith and in circumscribing relation to said access opening and for second opposite sense movement for release from such securement; (c) first and second means disposed interiorly of said closure member for travel with said closure member; and (d) indicating means in captive relation to said first means for movement therewith during said closure member first sense movement into securement with said vessel across said access opening, said first means tearing said indicating means in the course of said closure member second sense movement to provide such tamper indication, said second means engaging said indicting means following such tearing thereof and releasing said indicating means from said securement thereof with said vessel, said tamper-indicating element comprising a rupturable and tearable layer, said first means being secured in said rupturable and tearable layer, a stiffening layer juxtaposed with said rupturable and tearable layer, and a telltale layer juxtaposed with said stiffening layer and exposed therethrough upon tearing of said rupturable and tearable layer by said first means, and a container sealing layer juxtaposed with said telltale layer, said second means being disposed in spaced confronting relation to said container sealing layer.
Claim 8
Dependent Claim 27 words

Claim 9
Dependent Claim 45 words
The closure claimed in claim 6 wherein said closure member includes a top panel and a threaded skirt depending therefrom, said retaining-rupturing member extending downwardly from said top panel, said second means being situated upwardly of such skirt threads and downwardly of said retaining-rupturing member.
Claim 10
Dependent Claim 21 words
The closure claimed in claim 5 wherein both said first means and said second means are integral with said closure member.
Claim 11
Dependent Claim 182 words
A tamper-indicating container comprising: (a) a vessel for article containment and having an access opening; (b) a see-through closure for first sense movement relative to said vessel into securement therewith and in circumscribing relation to said access opening and for second opposite sense movement for release from such securement; (c) a tamper-indicating element in said closure; (d) first means movable with said closure for both retaining said tamper-indicating element with said closure and for selectively tearing said tamper-indicating element; and (e) second means in said closure for engaging said tamper-indicating element selectively following such tearing thereof for retaining said tamper-indicating element with said closure, said tamper-indicating element comprising a rupturable and tearable layer, said first means being secured in said rupturable and tearable layer, a stiffening layer juxtaposed with said rupturable and tearable layer, and a telltale layer juxtaposed with said stiffening layer and exposed therethrough upon tearing of said rupturable and tearable layered by said first means, and a container sealing layer juxtaposed with said telltale layer, said second means being disposed in spaced confronting relation to said container sealing layer.
