Abstract
Abstract A reclosable flexible container is provided as a pouch having front and back walls and a pouch opening at the upper edge thereof. The pouch has a cuff about the periphery of the pouch opening. A first fastener profile is affixed to either the cuff or the front wall of the pouch. A second fastener profile is affixed to the rear wall or to a cuff affixed to the rear wall. The fastener profiles may be selectively interlocked so as to seal the pouch with at least one wall of the pouch being interposed therebetween and engaged therein.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
165 words
A reclosable flexible container comprising: a pouch having front and back walls, and a pouch opening at the upper edge thereof, said pouch having a cuff extending downwardly from said pouch opening onto the exterior of said front and back walls and circumscribing said pouch opening, said cuff having an upper longitudinal edge attached to said front and rear walls, lateral edges sealed on the respective sides of said pouch, and a lower longitudinal edge substantially unattached to said front and rear walls; a first continuous fastener profile affixed to the interior of said cuff along said rear wall of said pouch and extending longitudinally thereon proximate said pouch opening and in alignment therewith; and a second continuous fastener profile affixed to the interior of said cuff along said front wall of said pouch in an alignment with said first continuous fastener profile, said continuous fastener profiles being constructed and arranged for selective interlocking with said front and rear walls of said pouch interposed therebetween.
Claim 2
Dependent Claim
165 words
A reclosable flexible container comprising: a pouch having front and back walls, and a pouch opening at the upper edge thereof, said pouch having a cuff extending downwardly from said pouch opening onto the exterior of said front and back walls and circumscribing said pouch opening, said cuff having an upper longitudinal edge attached to said front and rear walls, lateral edges sealed on the respective sides of said pouch, and a lower longitudinal edge substantially unattached to said front and rear walls; a first continuous fastener profile affixed to the interior of said cuff along said rear wall of said pouch and extending longitudinally thereon proximate said pouch opening and in alignment therewith; and a second continuous fastener profile affixed to the interior of said cuff along said front wall of said pouch in an alignment with said first continuous fastener profile, said continuous fastener profiles being constructed and arranged for selective interlocking with said front and rear walls of said pouch interposed therebetween.
Claim 3
Dependent Claim
39 words
The flexible reclosable container of claim 1 wherein said rear wall of said pouch extends above said front wall of said pouch so as to facilitate separation of said front wall from said rear wall when opening said pouch.
Claim 4
Dependent Claim
19 words
The reclosable flexible container of claim 1 wherein said pouch comprises a laminated film of at least two layers.
Claim 5
Dependent Claim
22 words
The flexible reclosable container of claim 1 wherein said cuff comprises a front lip affixed to said front wall of said pouch.
Claim 6
Dependent Claim
55 words
The flexible reclosable container of claim 1 wherein said cuff is constructed of a flexible polymeric material having a thickness substantially greater than the thickness of said front wall or said rear wall of said pouch so as to provide increased stiffness to said pouch opening, thereby facilitating digital manipulation and opening of said pouch.
Claim 7
Dependent Claim
25 words
The flexible reclosable container of claim 1 wherein said cuff is heat sealed to said pouch proximate said pouch opening and substantially in alignment therewith.
Claim 8
Dependent Claim
55 words
The flexible reclosable container of claim 1 wherein said cuff comprises a first thermoplastic material and said front and back walls of said pouch comprise a second thermoplastic material, said first thermoplastic material being stiffer than said second thermoplastic material so as to stiffen said pouch opening thereby facilitating opening and closing of said pouch.
Claim 9
Dependent Claim
36 words
The flexible reclosable container of claim 1 wherein said cuff is stiffer than said front and back walls of said pouch thereby stiffening said pouch opening so as to facilitate opening and closing of said pouch.
Claim 10
Dependent Claim
115 words
The reclosable flexible container of claim 1 wherein said first continuous fastener profile comprises a base portion and a groove portion, said base portion being affixed to the interior of said cuff across substantially its entire length and said groove portion being substantially unattached to said cuff; and said second continuous fastener profile comprises a base portion and a rib portion, said base portion being affixed to said cuff across substantially its entire length and said rib portion being substantially unattached to said cuff; said rib and groove being disposed in facing mating substantially parallel position so as to interlock when pressed together with said front and back wall of said pouch being interposed therebetween.
Claim 11
Dependent Claim
36 words
The flexible reclosable container of claim 1 wherein said cuff comprises a portion of said front wall folded over itself and a portion of said rear wall folded over itself, said cuff circumscribing said pouch opening.
Claim 12
Dependent Claim
49 words
The flexible reclosable container of claim 1 wherein said cuff comprises a first strip of plastic film sealed to said rear wall and a second strip of plastic film sealed to said front wall of said pouch, said first and second strips of plastic film circumscribing said pouch opening.
Claim 13
Dependent Claim
31 words
The flexible reclosable container of claim 11 wherein said cuff is fin sealed to said front wall and said back wall of said pouch about the periphery of said pouch opening.
Claim 14
Dependent Claim
31 words
The flexible reclosable container of claim 11 wherein said cuff is slit sealed to said front wall and said back wall of said pouch about the periphery of said pouch opening.
Claim 15
Dependent Claim
63 words
The flexible reclosable container of claim 1 wherein said cuff comprises a first prefabricated strip of plastic film and continuous fastener profile sealed to the exterior of said rear wall of said pouch, and a second prefabricated strip of plastic film and continuous fastener profile sealed to the exterior of said front wall of said pouch, said cuff facilitating manufacture of said container.
