Abstract
Abstract A tamper-indicating capped container includes an indicating member sealed across the container access port and the container cap is transparent and has capability for effecting visible change in the indicating member selectively in the course of container-opening sense movement of the cap. Tines may depend in cantilever manner from the cap interior to provide for tearing of the indicating member and the indicating member may be paper sheet material or a color change teltale.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
A container closure (10,100) for providing tamper .indication and of type having a closure member (18,118) for first sense movement relative to a container (12,112) into securement therewith and in circumscribing relation to an access opening of said container and for second different sense movement for release from such securement characterized as having at least one rupturing element (22,122) disposed interiorly of said closure member for travel with said closure member and supported for deflection relative to said closure member in said first sense movement of said closure member and for tearing a sealing member (24,124) disposed across said container access opening in the course of said second different sense movement of said closure member.
Claim 2
Dependent Claim
115 words
A container closure (10,100) for providing tamper .indication and of type having a closure member (18,118) for first sense movement relative to a container (12,112) into securement therewith and in circumscribing relation to an access opening of said container and for second different sense movement for release from such securement characterized as having at least one rupturing element (22,122) disposed interiorly of said closure member for travel with said closure member and supported for deflection relative to said closure member in said first sense movement of said closure member and for tearing a sealing member (24,124) disposed across said container access opening in the course of said second different sense movement of said closure member.
Claim 3
Dependent Claim
41 words
The closure member in claim 1 wherein said rupturing element is supported in said closure member for movement from first angular relation (26,126) thereto to succeeding lesser angular relation (28,128) thereto in the course of said first sense closure member movement.
Claim 4
Dependent Claim
33 words
The closure claimed in claim 2 wherein said closure member movements are rotative relative to said container and wherein said rupturing element is radially offset from the center of such closure member movements.
Claim 5
Dependent Claim
24 words
The closure claimed in claim 2 wherein said rupturing element is a cantilever-supported element depending from an interior surface (18a) of said closure member.
Claim 6
Dependent Claim
53 words
The container claimed in claim 4 wherein said closure member first and second sense movements are rotative relative to said container and wherein said cantilever-supported element is an elongate element secured to said closure member interior surface and orientated with its longitudinal axis substantially tangential to a radius of such closure member movements.
Claim 7
Dependent Claim
16 words
The closure claimed in claim 4 wherein said cantilever-supported element is integral with said closure member.
Claim 8
Dependent Claim
20 words
The closure claimed in claim 1 wherein plural such cantilever-supported elements (122) are equally mutually spaced in said closure member.
Claim 9
Dependent Claim
41 words
A tamper-indicating container including the closure of claim 1 fully moved in said first sense and circumscribing the access opening of said container and with said one rupturing element in engagement with a sealing member disposed across said container access opening.
Claim 10
Dependent Claim
17 words
9 . The container claimed in claim 8 wherein said sealing member (24) is a teltale seal.
Claim 11
Dependent Claim
20 words
The container claimed in claim 9 wherein said sealing member is a multilayer unit (124) including a teltale layer (124b).
