Abstract
Abstract A primary closure is permanently locked to the neck of a container in sealing relationship by means of the interlock between a continuous flange or bead on the neck of the container being engaged by ears on the collar or skirt of the primary closure. The primary closure body is sealed to the container by engagement between a resiliently mounted bead on the closure body engaging in axially loaded condition against the lip on the end of the neck of the container.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
155 words
A safety attachment for a primary closure to a container having a neck portion with an axially facing planar lip, said neck portion having a flange spaced axially from said lip, said primary closure having a top wall portion and a depending skirt portion, said wall portion having a resilient web formed by a recess in one of the surfaces around the peripheral portion thereof, a depending bead formed on said web and projecting axially into the open area within the confines of said skirt portion and adapted to be aligned with said lip on said container, means on the inside surface of said skirt portion whereby said closure is permanently affixed to said container by forcing said means past said flange on said neck of the container so that said means lock below the flange and the web is deformed as it urges said bead into sealing relation with said lip on said container.
Claim 2
Dependent Claim
155 words
A safety attachment for a primary closure to a container having a neck portion with an axially facing planar lip, said neck portion having a flange spaced axially from said lip, said primary closure having a top wall portion and a depending skirt portion, said wall portion having a resilient web formed by a recess in one of the surfaces around the peripheral portion thereof, a depending bead formed on said web and projecting axially into the open area within the confines of said skirt portion and adapted to be aligned with said lip on said container, means on the inside surface of said skirt portion whereby said closure is permanently affixed to said container by forcing said means past said flange on said neck of the container so that said means lock below the flange and the web is deformed as it urges said bead into sealing relation with said lip on said container.
Claim 3
Dependent Claim
60 words
A safety attachment for a primary closure as claimed in claim 1 wherein said lug means on the inside surface of the skirt portion includes at least two circumferentially spaced apart portions with said skirt portion having reduced thickness between said spaced apart portions which reduced thickness portions temporarily deform during the forcing of the lug means past the flange.
Claim 4
Dependent Claim
99 words
A safety attachment as claimed in claim 1 wherein said flange has a tapered upper surface for camming said means past said flange and said flange has a flat planar lower surface for positively locking said means on said closure axially beyond said flange, and the spacing between said lip and the axially remote surface of said flange on said container is slightly greater than the spacing between the bead on said web and axially facing surfaces on said means so that the means and bead are compressed axially against the flange and the lip, respectively, of said container.
Claim 5
Dependent Claim
169 words
A safety attachment for a primary closure to a container havIng a neck portion with an axially facing planar lip, said neck portion having a continuous flange therearound and spaced axially from said lip, said primary closure having a wall portion and a depending skirt portion, said wall portion having a resilient web formed by a pair of mating annular recesses in the upper and lower surfaces thereof around the outer peripheral portion thereof, a depending bead formed on said web and projecting axially into the open area within the confines of said skirt portion and adapted to be aligned with said lip on said container, lug means radially projecting from the inside surface of said skirt portion, whereby said closure is permanently affixed to said container by forcing said lug means past said flange on said neck of the container so that the lug means lock below the flange and the web is deformed as it urges said bead into sealing relation with said lip on said container.
Claim 6
Dependent Claim
169 words
A safety attachment for a primary closure to a container havIng a neck portion with an axially facing planar lip, said neck portion having a continuous flange therearound and spaced axially from said lip, said primary closure having a wall portion and a depending skirt portion, said wall portion having a resilient web formed by a pair of mating annular recesses in the upper and lower surfaces thereof around the outer peripheral portion thereof, a depending bead formed on said web and projecting axially into the open area within the confines of said skirt portion and adapted to be aligned with said lip on said container, lug means radially projecting from the inside surface of said skirt portion, whereby said closure is permanently affixed to said container by forcing said lug means past said flange on said neck of the container so that the lug means lock below the flange and the web is deformed as it urges said bead into sealing relation with said lip on said container.
Claim 7
Dependent Claim
102 words
A safety attachment as claimed in claim 4 wherein said flange has a tapered upper surface for camming said lug means past said flange and said flange has a flat planar lower surface for positively locking said lug means axially beyond said flange, and the spacing between said lip and the axially remote surface of said flange on said container is slightly greater than the spacing between the bead on said web and the axially inward facing surfaces on said lug means so that the lug means and bead are compressed axially against the flange and the lip, respectively, of said container.
