Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
A container and closure combination comprising: a container wall having an opening therein with an upstanding flange encircling said opening and having a radially projecting lip around said opening, said wall, flange, and lip being an integral homogeneous unit of plastic; a closure base received on said flange; and an anchor ring having an inverted annular channel received on said closure base, said anchor ring affixing said closure base to said flange.
Claim 2
Dependent Claim
72 words
A container and closure combination comprising: a container wall having an opening therein with an upstanding flange encircling said opening and having a radially projecting lip around said opening, said wall, flange, and lip being an integral homogeneous unit of plastic; a closure base received on said flange; and an anchor ring having an inverted annular channel received on said closure base, said anchor ring affixing said closure base to said flange.
Claim 3
Dependent Claim
34 words
The combination of claim 1 wherein: said anchor ring channel has a first wall with a marginal portion projecting into interlocking relationship with said lip to prevent separation of said flange from said ring.
Claim 4
Dependent Claim
34 words
The combination of claim 2 wherein: said anchor ring channel has a second wall, said upstanding flange and a portion of said closure base being squeezed between said first and second ring channel walls.
Claim 5
Dependent Claim
28 words
The combination of claim 3 wherein: said lip is outwardly turned, and said projecting marginal portion is an inwardly turned bead engaging said upstanding flange around its circumference.
Claim 6
Dependent Claim
71 words
The combination of claim 2 wherein: said anchor ring is rigid and the said channel thereof has a second wall, said closure base has an inverted annular channel with an inner wall, an outer wall and a bridging wall, said bridging wall resting on top of said upstanding flange, and said inner and outer walls being squeezed in sandwich relationship between said first and second waLls of said anchor ring channel.
Claim 7
Dependent Claim
57 words
The combination of claim 5 wherein: a circular portion of said closure base outside a line between said bridging wall and the top of said upstanding flange is of greater cross sectional area than the cross sectional area of said closure base at said line immediately between said bridging wall and the top of said upstanding flange.
Claim 8
Dependent Claim
86 words
A container closure combination comprising: a container wall having an opening therein with a plastic flange framing said opening, said flange having a laterally projecting lip thereof; a closure base made of plastic and received on said flange; and an anchor ring received on said closure base and having a channel shaped cross section, with the distance across the channel mouth being less than the combined thickness of said closure and said flange at said lip, whereby said ring is locked on said flange and base.
Claim 9
Dependent Claim
86 words
A container closure combination comprising: a container wall having an opening therein with a plastic flange framing said opening, said flange having a laterally projecting lip thereof; a closure base made of plastic and received on said flange; and an anchor ring received on said closure base and having a channel shaped cross section, with the distance across the channel mouth being less than the combined thickness of said closure and said flange at said lip, whereby said ring is locked on said flange and base.
Claim 10
Dependent Claim
37 words
The combination of claim 7 wherein: said flange and closure base have cold flow characteristics, and said anchor ring is rigid enough to prevent cold flow of said flange and lip and closure base through said mouth.
Claim 11
Dependent Claim
47 words
The combination of claim 7 wherein: said closure base has cold flow characteristics and includes a portion squeezed between inner and outer walls of the channel of said anchor ring into a relationship to said lip interfering with movement of said closure base axially along said flange.
Claim 12
Dependent Claim
22 words
The combination of claim 9 wherein: said squeezed portion is a lower marginal portion of a skirt wall of said closure base.
