Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 166 words
In a sealing-hinging arrangement for a carton, the combination of: (a) a body member including a rim presenting a sealing surface; (b) a separate lid member including a rim presenting a sealing surface; (c) a relatively thin, flexible, membrane formed of a sealable material and folded upon itself to present two sections separated from each other by a fold line; (d) one of said sections being of sufficient size and shape to cover the entire sealing surface of the rim of one of said members, and the other of said sections being of sufficient size and shape to cover at least a portion of the sealing surface of the rim of the other member at one side of said other member; (e) said sections being sealed to the rim sealing surfaces of the respective members to effect a hermetic seal therebetween; (f) said members being free from direct connection to each other, with said membrane functioning as the sole connection and hinge means between said members.
Claim 2
Dependent Claim 166 words
In a sealing-hinging arrangement for a carton, the combination of: (a) a body member including a rim presenting a sealing surface; (b) a separate lid member including a rim presenting a sealing surface; (c) a relatively thin, flexible, membrane formed of a sealable material and folded upon itself to present two sections separated from each other by a fold line; (d) one of said sections being of sufficient size and shape to cover the entire sealing surface of the rim of one of said members, and the other of said sections being of sufficient size and shape to cover at least a portion of the sealing surface of the rim of the other member at one side of said other member; (e) said sections being sealed to the rim sealing surfaces of the respective members to effect a hermetic seal therebetween; (f) said members being free from direct connection to each other, with said membrane functioning as the sole connection and hinge means between said members.
Claim 3
Dependent Claim 22 words
An arrangement according to claim 1, wherein said sealing surfaces are flat and raised from the surrounding portions of the respective members.
Claim 4
Dependent Claim 21 words
An arrangement according to claim 1, wherein said membrane is formed of a metallic material that is adapted for induction sealing.
Claim 5
Dependent Claim 16 words
An arrangement according to claim 1, wherein said membrane is peelably sealed to said sealing surfaces.
Claim 6
Dependent Claim 24 words
An arrangement according to claim 1, wherein said membrane sections are each large enough to cover the entire sealing surfaces of their respective members.
Claim 7
Dependent Claim 43 words
An arrangement according to claim 1, wherein one of said membrane sections can be peeled off of all but a portion of its related sealing surface so that the membrane can still function as a hinge after the carton has been initially opened.
Claim 8
Dependent Claim 21 words
An arrangement according to claim 1, wherein the membrane is sealed in a folded position with the closure on the container.
Claim 9
Dependent Claim 21 words
An arrangement according to claim 1, wherein the membrane is sealed in an unfolded position with the closure alongside the container.
