Abstract
Abstract This relates to a neck structure on a domed container end for receiving a thermoplastic material closure. It particularly relates to containers having very thin walls on the order of 6-9 mils and wherein the container is formed of a metal having a grain which generally defines a fold line. In order to avoid undue deformation of the lower part of the usual ring which receives the closure body, the domed end immediately adjacent an encircling ring is provided with an upstanding bead which is shock absorbent and functions resiliently to reinforce the lower part of the ring and to restore it to its original configuration after the body of the closure has been pressed through the ring. Further, the closure is provided with a depending skirt which is circumferentially aligned with the bead and slightly axially spaced therefrom so that when an undue load is placed on the closure, that load may be primarily transmitted, after initial deflection of the neck ring, to the domed end through the closure skirt and the bead. This abstract forms no part of the specification of this application and is not to be construed as limiting the claims of the application.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
80 words
A neck and closure assembly for a container wherein said neck comprises: a tubular neck member integrally formed with a portion of a container and extending axially from the remainder of the container for receiving a closure, said neck member including a radially and axially inturned lip, a retainer ring carried by said lip extending axially of the container, said closure comprising a tubular element mounted within said ring and having means in fluid-tight engagement with said tubular neck member.
Claim 2
Dependent Claim
80 words
A neck and closure assembly for a container wherein said neck comprises: a tubular neck member integrally formed with a portion of a container and extending axially from the remainder of the container for receiving a closure, said neck member including a radially and axially inturned lip, a retainer ring carried by said lip extending axially of the container, said closure comprising a tubular element mounted within said ring and having means in fluid-tight engagement with said tubular neck member.
Claim 3
Dependent Claim
20 words
The invention according to claim 1 wherein said lip is generally frustoconical and tapers toward the interior of the container.
Claim 4
Dependent Claim
16 words
The invention according to claim 1 wherein said ring is generally axially coextensive with said lip.
Claim 5
Dependent Claim
51 words
The invention according to claim 1 wherein said closure is formed of plastic material and said ring and lip have inner ends joined by a rounded portion defining a dull non-cutting edge, and a shoulder on said tubular element of the closure being in a sealing engagement with said non-cutting edge.
Claim 6
Dependent Claim
38 words
The invention according to claim 1 wherein said ring has an axially outer end with a reinforcing curl providing a blunt surface, and another shoulder on said tubular element of said closure opposing said surface of said curl.
Claim 7
Dependent Claim
21 words
The invention according to claim 1 wherein said lip and said ring are in closely nested relation and both are frustoconical.
Claim 8
Dependent Claim
79 words
A container neck for receiving a closure assembly, said container neck comprising a container member terminating in a container neck and a closure seated in said container neck in sealed relation, said container neck including a ring and an upstanding bead radially surrounding said ring and directly connected to said ring in a blunt axially inner juncture to form shock absorbing and reinforcing means controlling expansion of said ring and said blunt juncture during the application of a closure.
Claim 9
Dependent Claim
79 words
A container neck for receiving a closure assembly, said container neck comprising a container member terminating in a container neck and a closure seated in said container neck in sealed relation, said container neck including a ring and an upstanding bead radially surrounding said ring and directly connected to said ring in a blunt axially inner juncture to form shock absorbing and reinforcing means controlling expansion of said ring and said blunt juncture during the application of a closure.
Claim 10
Dependent Claim
34 words
A container neck in accordance with claim 7 wherein said bead includes an outer generally upstanding tubular neck element joined to a radially and axially inwardly sloping lip by an axially outer convex juncture.
Claim 11
Dependent Claim
85 words
A container neck in accordance with claim 8 together with a closure seated in said container neck, said closure including a cylindrical body extending axially through said ring and having an axially upwardly facing shoulder engaging said blunt axially inner juncture, said closure also having an outer depending skirt radially surrounding an upper part of said ring and being in generally radially aligned and axially spaced relation to said axially outer convex juncture for applying compressive loadings directly to said container neck through said bead.
Claim 12
Dependent Claim
41 words
A container neck in accordance with claim 7 together with a closure seated in said container neck, said closure including a cylindrical body extending axially through said ring and having an axially upwardly facing shoulder engaging said blunt axially inner juncture.
Claim 13
Dependent Claim
39 words
A neck structure for a container comprising a tubular neck member having a radially and axially inturned lip terminating in an inner edge, and an integral closure-supporting retaining ring connected to said inner edge and extending axially outwardly therefrom.
Claim 14
Dependent Claim
39 words
A neck structure for a container comprising a tubular neck member having a radially and axially inturned lip terminating in an inner edge, and an integral closure-supporting retaining ring connected to said inner edge and extending axially outwardly therefrom.
Claim 15
Dependent Claim
38 words
The invention according to claim 11 wherein said element, lip and ring are disposed in nested relation and said ring has a blunt seating edge portion disposed axially outwardly of the juncture of said ring and said lip.
Claim 16
Dependent Claim
14 words
The invention according to claim 12 wherein said lip and ring are both frustoconical.
Claim 17
Dependent Claim
29 words
The invention according to claim 11 wherein said lip and said ring define a cantilevered shock-absorbing resilient structure adapted for impact application, without collapsing, of a closure element thereto.
Claim 18
Independent Claim
83 words
A method of assembling a closure of heat softenable plastic material having a sleeve portion with a neck structure of a thin wall metal container, said method comprising the steps of forming said neck structure with a plurality of interconnected nested elements in a load buffering assembly, heating said closure to soften the material of the closure, then forcibly axially impacting said sleeve portion into the innermost one of the nested elements in sealing engagement therewith, then cooling said closure to ambient temperature.
Claim 19
Independent Claim
83 words
A method of assembling a closure of heat softenable plastic material having a sleeve portion with a neck structure of a thin wall metal container, said method comprising the steps of forming said neck structure with a plurality of interconnected nested elements in a load buffering assembly, heating said closure to soften the material of the closure, then forcibly axially impacting said sleeve portion into the innermost one of the nested elements in sealing engagement therewith, then cooling said closure to ambient temperature.
