Abstract
Abstract A metal container having a vacuum sealed closure adapted for convenient and safe removal and which is reclosable. A container shell is formed at its open end with an intrusive shoulder and an annular rim formed by folding back the raw metal shell edge. The rim defines an outwardly and downwardly inclined ledge to cooperate with an annular gasket on the closure member for effecting a hermetical seal under the force of atmospheric pressure acting against a vacuum within the container. An annular bead on the rim functions to retain the closure member in place during the capping and sterilizing operations. One preferred embodiment provides a flat gasket on the inside surface of the closure member to cooperate in sealing relationship with the upper edge of the shell rim and in another preferred embodiment the annular gasket is used without the flat gasket.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A container for a comestible product comprising an open-ended metal shell for holding the product, the shell including an annular rim at said open end, the rim including an outer margin defined by an outwardly and reversely folded shell edge, the rim outer margin including an annular locking bead projecting outwardly from said rim and an annular ledge disposed below said bead, said ledge including means forming a downwardly and outwardly inclined annular sealing surface, a closurE member to close the shell open end including a lid having at its outer periphery an annular, downwardly projecting bead, and gasket means carried by the lid, the gasket means including an annular member of an elastomeric material disposed below the peripheral margin of said lid, the annular member being formed with an inwardly projecting portion disposed in sealing relationship with said sealing surface to provide an hermetical seal therewith under the influence of a vacuum within the shell.
Claim 2
Dependent Claim
156 words
A container for a comestible product comprising an open-ended metal shell for holding the product, the shell including an annular rim at said open end, the rim including an outer margin defined by an outwardly and reversely folded shell edge, the rim outer margin including an annular locking bead projecting outwardly from said rim and an annular ledge disposed below said bead, said ledge including means forming a downwardly and outwardly inclined annular sealing surface, a closurE member to close the shell open end including a lid having at its outer periphery an annular, downwardly projecting bead, and gasket means carried by the lid, the gasket means including an annular member of an elastomeric material disposed below the peripheral margin of said lid, the annular member being formed with an inwardly projecting portion disposed in sealing relationship with said sealing surface to provide an hermetical seal therewith under the influence of a vacuum within the shell.
Claim 3
Dependent Claim
42 words
A container as in claim 1 wherein said annular member is mounted adjacent the inside margin of the lid bead and said inwardly projecting portion comprises an inner peripheral edge of said annular member, said edge being seated against said sealing surface.
Claim 4
Dependent Claim
56 words
A container as in claim 2 wherein said annular member is adapted to flex over the rim locking bead for retaining the closure member during a container capping operation, and said edge of the annular member is adapted to be urged against said inclined sealing surface responsive to atmospheric presence closing force on the closure member.
Claim 5
Dependent Claim
43 words
