Abstract
Abstract This disclosure relates to a tamper-indicating band which is utilized in conjunction with a closure for normally preventing the distortion of the closure as would be required to effect the removal of the closure. A tamper-indicating ring includes a continuous band which must be ruptured in order to remove the tamper-indicating ring. When the processing of the container assembly requires the introduction of heat, the tamper-indicating ring is heated and the band expands and then shrinks. Difficulties encountered with this first expansion and later shrinkage have been solved by forming the band in a plurality of sections connected together by expansion segments.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
79 words
A closure assembly comprising a closure member including a body having an end panel and a depending skirt and a sealing ring within said body for engaging a container sealing surface, and a tamper-indicating ring carried by said skirt and having a portion disposed radially inwardly of said skirt for normally preventing radial inward deflection of said skirt, said tamper-indicating ring being characterized in that it includes expansion means for accommodating expansion of said tamper-indicating ring during heating thereof.
Claim 2
Dependent Claim
79 words
A closure assembly comprising a closure member including a body having an end panel and a depending skirt and a sealing ring within said body for engaging a container sealing surface, and a tamper-indicating ring carried by said skirt and having a portion disposed radially inwardly of said skirt for normally preventing radial inward deflection of said skirt, said tamper-indicating ring being characterized in that it includes expansion means for accommodating expansion of said tamper-indicating ring during heating thereof.
Claim 3
Dependent Claim
44 words
The closure assembly of claim 1 wherein said tamper-indicating ring includes a continuous band having at least one line of weakening therein for effecting rupture of said band for freeing said tamper-indicating ring for removal, and said expansion means being formed in said band.
Claim 4
Dependent Claim
46 words
The closure assembly of claim 1 wherein said skirt terminates in a curl and said tamper indicating band has a socket receiving said curl for maintaining said closure assembly as a unit for application, and during expansion of said band, said curl acting as a track.
Claim 5
Dependent Claim
24 words
The closure assembly of claim 1 wherein said closure assembly is carried by a container having a sealing finish engaged by said sealing ring.
Claim 6
Dependent Claim
31 words
The closure assembly of claim 4 wherein there is a vacuum within said container with said vacuum acting at least in part as means for retaining said closure on said container.
Claim 7
Dependent Claim
22 words
The closure assembly of claim 1 wherein said tamper-indicating ring includes a band, said band including band portions joined by expansion portions.
Claim 8
Dependent Claim
14 words
The closure assembly of claim 6 wherein said expansion portions include reversely folded parts.
Claim 9
Dependent Claim
90 words
A tamper indicating ring for use with a closure having a depending skirt intended to be spaced from an adjacent container wall, said tamper-indicating ring including a continuous band having at least one line of weakening for effecting rupture of said band, said band having radially inwardly projecting lug means for positioning between a container and a closure skirt, and means for interlocking said ring to a closure skirt, said tamper-indicating ring being characterized in that it includes expansion means for accommodating expansion of said tamper-indicating ring during heating thereof.
Claim 10
Dependent Claim
90 words
A tamper indicating ring for use with a closure having a depending skirt intended to be spaced from an adjacent container wall, said tamper-indicating ring including a continuous band having at least one line of weakening for effecting rupture of said band, said band having radially inwardly projecting lug means for positioning between a container and a closure skirt, and means for interlocking said ring to a closure skirt, said tamper-indicating ring being characterized in that it includes expansion means for accommodating expansion of said tamper-indicating ring during heating thereof.
Claim 11
Dependent Claim
25 words
The tamper-indicating ring of claim 8 wherein said lug means are in the form of a plurality of radial lugs disposed in circumferentially spaced relation.
Claim 12
Dependent Claim
45 words
The tamper-indicating ring of claim 8 wherein said lug means are in the form of a plurality of radial lugs disposed in circumferentially spaced relation, and socket means formed between said lugs and said band for interlockingly receiving a free edge of a closure skirt.
Claim 13
Dependent Claim
16 words
The tamper-indicating ring of claim 8 wherein said band includes band portions joined by expansion portions.
Claim 14
Dependent Claim
14 words
The tamper-indicating ring of claim 11 wherein said expansion portions include reversely folded parts.
