Abstract

Abstract The disclosure relates to a closure system for a film wall package including profile strips (2,4) having a reclosable seal (6,8) of the interlocking type, flange elements (10,12) and, adjacent the reclosable seal, an adhered strip of peelable material (22,24). The peelable material (22,24) and the profile strip (2,4) may be co-extruded. With packaging film attached to the profile strips, typically to the flange elements, the resulting product may be used in a horizontal form, fill and seal operation, at which time the reclosable elements are mated and a peel seal is formed. The peel seal may be disposed on either side of the reclosable seal with respect to the interior of the package. The benefits of both peel seals and reclosable seals may be obtained by using optimum materials for those elements while, at the same time, allowing the use of a different material for the walls of the package.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 54 words
A method of producing a sealing system for a package comprising the steps of: forming first and second profile strips, each strip comprising longitudinally-extending reclosable seal means of the interlocking type; adhering a strip of peelable material to at lease one of the profile strips substantially parallel to and proximate the reclosable seal means.
Claim 2
Independent Claim 54 words
A method of producing a sealing system for a package comprising the steps of: forming first and second profile strips, each strip comprising longitudinally-extending reclosable seal means of the interlocking type; adhering a strip of peelable material to at lease one of the profile strips substantially parallel to and proximate the reclosable seal means.
Claim 3
Dependent Claim 26 words
The method of claim 1, wherein said forming and adhering steps comprise the step of co-extruding a profile strip and an adhered strip of peelable materi­al.
Claim 4
Dependent Claim 44 words
The method of claim 1, said forming step comprising the step of forming first and second profile strips each of which comprises a flange element, further comprising the step of adhering web­bing to the respective flange elements, thereby forming opposite sides of a package.
Claim 5
Dependent Claim 29 words
The method of claim 3, wherein said forming step and said adhering steps comprise the step of co­extruding a profile strip, an adhered strip of peelable material, and webbing.
Claim 6
Dependent Claim 53 words
A sealing system for a package, the sealing system comprising: first and second profile strips, each strip comprising longitudinally-extending reclosable seal means of the interlocking type; and a seal of peelable material disposed between the profile strips and taking the form of a strip extending longitudinally of and proximate the reclosable seal means.
Claim 7
Dependent Claim 53 words
A sealing system for a package, the sealing system comprising: first and second profile strips, each strip comprising longitudinally-extending reclosable seal means of the interlocking type; and a seal of peelable material disposed between the profile strips and taking the form of a strip extending longitudinally of and proximate the reclosable seal means.
Claim 8
Dependent Claim 42 words
The invention of claim 5 wherein: said first and second profile strips respec­tively comprising flange members, the invention further comprising a webbing adhered to the respective flange elements of said seal­ing system, the webbing comprising at least one wall of a package.
Claim 9
Dependent Claim 10 words
A resealable profile strip having a peelable material co-extruded thereon.
Claim 10
Dependent Claim 10 words
A resealable profile strip having a peelable material co-extruded thereon.
