Abstract

Abstract A reclosable container having an annular ring with an inwardlyangled upwardly-extending substantially straight shoulder and a surmounting vertical throat whose interior surface frictionally sealingly engages the outer surface of a vertical to inwardlytapered friction wall on the container plug to provide a tight closure which minimizes leakage and plug dislodgment upon tipping. The diameter of the base of the friction wall is greater than the throat diameter, and the junction of the plug central panel and friction wall is disposed lower than the junction of the ring shoulder and throat.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 187 words
A container comprising: a metal can body; an annular ring joined to one end of said can body by a double seam, said ring having a substantially U-shaped channel, said channel being formed by a countersink wall, which merges directly into a substantially arcuate wall, which in turn merges into an inwardly-angled upwardly-extending substantially straight shoulder, said shoulder adjoining a vertical to inwardly-angled throat at an inner portion of said ring above said seam; and a metal plug, said plug having a recessed concavely-profiled flexible central panel and an annular, inwardly-angled friction wall adjoining said central panel, the outer diameter of the base of said plug friction wall being greater than the inner diameter of said throat, and the junction of said central panel and said friction wall having a reformed radius of greater rigidity than that of its original radius or that of the central panel or inwardly-angled friction wall, said plug junction being lower than the junction of said shoulder and said throat, such that the outer surface of said friction wall fits snugly in frictional sealing engagement with the interior surface of said throat.
Claim 2
Dependent Claim 187 words
A container comprising: a metal can body; an annular ring joined to one end of said can body by a double seam, said ring having a substantially U-shaped channel, said channel being formed by a countersink wall, which merges directly into a substantially arcuate wall, which in turn merges into an inwardly-angled upwardly-extending substantially straight shoulder, said shoulder adjoining a vertical to inwardly-angled throat at an inner portion of said ring above said seam; and a metal plug, said plug having a recessed concavely-profiled flexible central panel and an annular, inwardly-angled friction wall adjoining said central panel, the outer diameter of the base of said plug friction wall being greater than the inner diameter of said throat, and the junction of said central panel and said friction wall having a reformed radius of greater rigidity than that of its original radius or that of the central panel or inwardly-angled friction wall, said plug junction being lower than the junction of said shoulder and said throat, such that the outer surface of said friction wall fits snugly in frictional sealing engagement with the interior surface of said throat.
Claim 3
Dependent Claim 52 words
The container of claim 1 wherein said annular ring is joined to said can body by a conventional double seam, the terminal portion of said throat is curled and said plug has an annular, inverted, substantially U-shaped wall adjoining said friction wall and complementarily sitting in frictional engagement on said throat curl.
