Abstract

Abstract An improved seal between a wide mouth and its closure is obtained by providing a continuous resilient exterior skirtlike flange depending from the lip of the container and a corresponding flange on the closure. The closure flange has an annular rib which sealingly engages and forces the continued container flange resiliently inwardly. A score line above the rib and a tear tab integral with the portion of the closure below the score line combine to permit the lower portion of the closure flange to be removed to facilitate removal of the remaining portions of the closure from the container.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 156 words
A wide-mouth container and closure assembly, comprising a container having side portions extending upwardly and terminating in a lip which defines the mouth of said container, and a continuous, skirtlike, exterior flange depending downwardly from said lip and diverging from said side portions; and a closure having a top portion spanning and closing the mouth of the container and overlying said container lip, and a downwardly depending continuous flange extending circumjacent said container flange and having a continuous, inwardly formed annular rib disposed entirely above the lowermost extremity of the container flange and sealingly engaging and forcing said container flange resiliently inwardly, said closure member flange portion having a peripheral score line spaced above said rib, and a tear tab integral with the portion of said closure below said score line, whereby the lower portion of said closure flange may be removed to permit subsequent removal of the remaining portions of the closure from said container.
Claim 2
Dependent Claim 156 words
A wide-mouth container and closure assembly, comprising a container having side portions extending upwardly and terminating in a lip which defines the mouth of said container, and a continuous, skirtlike, exterior flange depending downwardly from said lip and diverging from said side portions; and a closure having a top portion spanning and closing the mouth of the container and overlying said container lip, and a downwardly depending continuous flange extending circumjacent said container flange and having a continuous, inwardly formed annular rib disposed entirely above the lowermost extremity of the container flange and sealingly engaging and forcing said container flange resiliently inwardly, said closure member flange portion having a peripheral score line spaced above said rib, and a tear tab integral with the portion of said closure below said score line, whereby the lower portion of said closure flange may be removed to permit subsequent removal of the remaining portions of the closure from said container.
Claim 3
Dependent Claim 37 words
The structure of claim 1 wherein said closure top portion includes a recessed central panel and an upwardly extending flange portion in snugly fitting relationship with the interior surface of said container side portions adjacent said lip.
Claim 4
Dependent Claim 25 words
The structure of claim 1 wherein said container is formed of a resilient, flexible plastic material and said closure is formed of thin sheet metal.
Claim 5
Dependent Claim 152 words
A wide-mouth container and closure assembly, comprising a container having side portions extending upwardly and terminating in a lip which defines the mouth of said container, and a continuous, skirtlike, exterior flange depending downwardly from said lip and diverging from said side portions; and a closure having a top portion spanning and closing the mouth of the container and overlying said container lip, and a downwardly depending continuous flange extending circumjacent said container flange and having a plurality of continuous, inwardly-formed annular ribs, at least one of said ribs sealingly engaging and forcing said container flange resiliently inwardly, said closure member flange portion having a peripheral score line spaced above said rib, and a tear tab integral with the portion of said closure below said score line, whereby the lower portion of said closure flange may be removed to permit subsequent removal of the remaining portions of the closure from said container.
Claim 6
Dependent Claim 152 words
A wide-mouth container and closure assembly, comprising a container having side portions extending upwardly and terminating in a lip which defines the mouth of said container, and a continuous, skirtlike, exterior flange depending downwardly from said lip and diverging from said side portions; and a closure having a top portion spanning and closing the mouth of the container and overlying said container lip, and a downwardly depending continuous flange extending circumjacent said container flange and having a plurality of continuous, inwardly-formed annular ribs, at least one of said ribs sealingly engaging and forcing said container flange resiliently inwardly, said closure member flange portion having a peripheral score line spaced above said rib, and a tear tab integral with the portion of said closure below said score line, whereby the lower portion of said closure flange may be removed to permit subsequent removal of the remaining portions of the closure from said container.
Claim 7
Dependent Claim 41 words
The structure of claim 4 wherein at least one of said ribs sealingly engages and forces said container flange resiliently inwardly, and at least another one of said ribs sealingly engages the side portions of said container below said container flange.
Claim 8
Dependent Claim 182 words
A wide-mouth container and closure assembly, said container being formed of a resilient, flExible material having side portions which extend upwardly to a wide-mouth lip, and having a continuous skirtlike exterior flange depending downwardly and diverging outwardly from said side portions from said lip, said closure including a top portion having a recessed central panel, an upwardly extending flange and an outwardly extending lip-bridging portion, and a downwardly depending flange portion disposed in circumjacent juxtaposed relationship with respect to said container flange and having at lease one continuous inwardly formed annular rib sealingly engaging and forcing said container flange inwardly, said closure flange having a peripheral score line spaced above said rib and having an end portion which traverses said sealing rib, and a tear tab integral with the bottom portion of said closure below said score line, said tear tab being disposed below said rib and having a side which connects with said score line end portion, whereby the lower portion of said closure flange may be removed to permit removal of the remaining portions of the closure from said container.
Claim 9
Dependent Claim 182 words
A wide-mouth container and closure assembly, said container being formed of a resilient, flExible material having side portions which extend upwardly to a wide-mouth lip, and having a continuous skirtlike exterior flange depending downwardly and diverging outwardly from said side portions from said lip, said closure including a top portion having a recessed central panel, an upwardly extending flange and an outwardly extending lip-bridging portion, and a downwardly depending flange portion disposed in circumjacent juxtaposed relationship with respect to said container flange and having at lease one continuous inwardly formed annular rib sealingly engaging and forcing said container flange inwardly, said closure flange having a peripheral score line spaced above said rib and having an end portion which traverses said sealing rib, and a tear tab integral with the bottom portion of said closure below said score line, said tear tab being disposed below said rib and having a side which connects with said score line end portion, whereby the lower portion of said closure flange may be removed to permit removal of the remaining portions of the closure from said container.
Claim 10
Dependent Claim 23 words
The structure of claim 6 wherein the lower extremities of said closure flange portion are formed inwardly and lock under said container flange.
